The third emperor of the Sui Dynasty

Chapter 841 Fail once, ten times, ten times, not a hundred times
"Your Majesty, Emperor of the Sui Dynasty, I don't know what a cement board is, but these boxes seem to be made of volcanic ash..." Ji Shi Changdan saw that Yang Tong cared about the box, and said quickly.

"Volcanic ash?" Yang Tong now understands the origin of this box. The substances melted by the heat of active volcanoes are natural cementitious materials. The volcanic ash and volcanic stones formed by them are ground into fine powder and mixed with lime and water, which can not only harden in the air , and can harden in water, this is natural cement.On the other hand, the four islands of Wonu are volcanoes and earthquake-prone areas, and it is normal for the Ainu people to occasionally discover the characteristics of volcanic ash.

The Central Plains is a country with many volcanoes. Although most of them have become extinct volcanoes and dormant volcanoes in later generations, there were many active volcanoes in the territory during the Sui Dynasty. Even if artificial cement is not available now, volcanic rocks can be used instead. .

"Exactly." Ji Shichangdan nodded.

"My lord!" Jiang Xingben bowed his hands and said disdainfully, "This volcanic ash box seems to be magical, but it is actually insignificant."

"How did you know that?" Yang Tong was surprised again, hearing Jiang Xingben's words, it seemed that he also knew the properties of volcanic ash.

"This volcanic clay box, if it is made thin, will not withstand falling. If it is made thick, it will be very heavy and heavy, and it cannot be carried by one person. How can there be a wooden box that is light?" Jiang Xingben said: "The key is that this thing is easy to regain moisture. , the paper is rotten, it's not worth mentioning."

"So, you did it?" Yang Tong asked with a dark face.

"Exactly." Jiang Xingben said proudly.

"..." Yang Tong gritted his teeth angrily, and suddenly felt that he really deserved to be beaten.
NN bears.

Besides cement, how many technologies have these bastards from the Ministry of Industry neglected? ?

"Your Majesty the Emperor of the Sui Dynasty!" the neglected Jishi Changdan cried: "We Ainu people fought fiercely against the tyranny of the Japanese slaves in the first year of Shengwu, but we were too weak and were defeated by Suwo. Ma Zi brutally suppressed us, and we were punished by the old lady of the Emperor Tuigu. Animal skins, grain, iron ore, etc. could only get one-third of the previous prices. My people froze to death and starved to death every day. Fortunately, the Chinese Navy has been here for more than a year. Come on, cut off the waterway of the Japanese slaves going north to Ezo Island, so that we Ezo people have a breathing space, so we come to ask you, I hope you can help us!"

At the end, Ji Shichangdan almost burst into tears.

"I estimate and believe that you are related to Xu Fu."

It's normal for Xu Fu's group and their descendants to engage in male-female relationships with the aborigines.But this is not the key, the key is that they can be cannon fodder.

"Thank you, Emperor Sui, for your approval." Ji Shi Changdan felt that the relationship was getting closer.

Yang Tong asked, "How many people do you have?"

Ji Shichangdan looked at Yang Tong expectantly: "Around 20."

Yang Tong was a little surprised by this amount, as the Sui cannon fodder was enough, he said with a smile: "I helped you."

With a "plop", Ji Shi Changdan was so excited that he knelt on the ground again, crying, "You are really the most benevolent Son of Heaven in the world!"

"Hehe..." Hearing this, Yang Tong laughed.

You guys are also worthy of talking about kindness?It's an insult to the word...

Yang Tong didn't have even the slightest liking for the inferior ethnic groups living on the four islands of Japanese slaves.These people have always respected, feared, envied, and envied the Central Plains. When the Central Plains was strong, they behaved like bunnies, with a harmless look on their faces; Insatiable!
"How about this, I will subsidize you with [-] sets of weapons and equipment, and let the navy send your soldiers south to Honshu Island."

"This... Seriously?" Chief Jishi Dan suddenly raised his head, his eyes widened, and he really couldn't believe his ears.

Yang Tong said gently: "Da Sui loves people, not only patriots, but also all peace-loving people! Helping the weak live a better life has always been Da Sui's unswerving national policy!"

Jishi Changdan was so moved that he kowtowed: "The Ainu people will always remember your deep friendship! Jishi Changdan hereby promises that as long as there is one Ainu person alive, he will take Tai Sui as the main one. As long as the emperor of the Sui Dynasty gives an order, the Ainu people will go through fire and water and die!"

"I have three conditions."

"Please tell me." Jishi Changdan was very excited. He thought that Yang Tong would at most recognize the Ainu people so that they could pretend to be arrogant, but unexpectedly he got so many good things!However, although he didn't know the phrase 'nothing to be courteous is nothing but steal', it didn't mean he didn't understand the truth.So when Yang Tong said that there were conditions, he believed it even more.

"First, the Tai Sui Navy will choose a place on your land to build a military port in the future. It will be controlled by our Tai Sui with a radius of [-] miles. Forget it; third, if there are mines in these places in the future, they will all belong to my Tai Sui; fourth, if my Tai Sui people walk in other places and have conflicts with your people, they can only be judged by our Tai Sui. You must not interfere."

Giving the Ainu people [-] sets of obsolete weapons and equipment is to give them the courage to fight the Japanese slaves. When they are dying, the Great Sui army will come down like heavenly soldiers to save the Ainu people from the fire and the genocide. One step further, the Ainu people would just cry and beg Tai Sui to be their protector!It's just that it's easier to invite the gods than to send them away. Once the Great Sui army set foot on that land, it's not the Ainu people who have the final say.

Yang Tong's asking for these three conditions was nothing more than taking off the other party's guard.

"It's all right." Ji Shi Changdan slapped his chest loudly. If the Sui Navy hadn't isolated them from the Japanese slaves, the Ainu people would probably still be bullied by the Japanese slaves. How could they have the right to challenge the Japanese slaves?And with their small population, even if they got [-] sets of weapons and equipment, it was obviously difficult to fight the Japanese slaves for a long time. Even if Yang Tong didn't have the condition to garrison troops, he still had to plead.

Mine and so on, that was also after the Ainu people established the country and occupied Honshu Island, and it has nothing to do with the present.

Ji Shi Changdan's goal was fulfilled, and seeing that Yang Tong had nothing to say, he resigned with gratitude.

He felt that this mission went very smoothly. Not only did he gain the friendship of the Sui Dynasty, but he also gave the tribe the power to fight against the devil, so that the tribe could hope to regain the legendary beautiful, rich, warm and warm Kanto Plain.He didn't know that at the same time, he brought another demon to his nation, but this demon looked very kind and benevolent.

"The Holy One really wants to support the Ainu people?" Yang Gongren asked after Jishi Changdan left. Sui Yiyi; he was afraid that Yang Tong would be stimulated by Xu Fu's descendants and go to the boundless and risky sea to find immortals who did not exist.

"I just support the war between the Ainu people and the Japanese slaves, and wait for them to lose both, and then take away the four islands in the sea."

"The island is really so good?"

"Xu Jingzong was at the Gold and Silver Pagoda in Ziwei City last time, have you forgotten? Let me tell you, that is only one ten-thousandth. Once the islands of the Wa Kingdom are brought into the hands of the Great Sui, then my Great Sui will surely enrich the national treasury."

When they heard the Jinyin Pagoda, everyone fell silent.Even now, the shock in everyone's hearts has not disappeared.

Yang Tong said again: "I don't have any good feelings for the Ainu people and Japanese slaves. It doesn't matter if they are extinct. I am not interested in those islands, as long as the islands are gold, silver and copper..."

"..." Everyone said in their hearts: Are you not interested in thinking about other people's gold, silver and copper?

"Don't talk about this." Yang Tong waved his hand and said to Jiang Xingben: "You know the effect of volcanic ash, why didn't you tell me earlier?"

"Your Majesty, I just said that this thing is useless?" Jiang Xingben said blankly.

"You are useless." Yang Tong scolded with a smile, "Since you know the characteristics of volcanic ash, do you know that volcanic ash mud can be mixed with clean gravel, sand, and lime powder to solidify into a board?"

Jiang Xingben nodded: "I know!"

Yang Tong was even more speechless, and could only give hints bit by bit: "It's not easy to build bridges since ancient times. What's the reason? It's because the river is too wide and there are not so long timbers flying across the river. Of course, you can also build more wooden bridges in the river." The pier, however, is covered with wooden boards, but the wooden pier is not only easy to rot, it is also easy to be knocked down by the wood flowing from the upstream; if the flood floods, when the upstream tree trunks and other sundries get stuck on the pier, the entire bridge will be washed away. Is it this way?"

"Yes." Jiang Xingben nodded again
"It's good to understand." Yang Tong changed the subject: "If you build a dam on the river during the dry season and divert the river water to other places, you can clear the dry area out of the rock bottom. Put iron piles into them, and then pour volcanic mud layer by layer like building a city wall. After it solidifies, isn’t this bridge pier, which is completely integrated with the stone bottom, the same as the mainstay? If the bridge piers are made of volcanic mud, then a wide bridge deck can be erected on them. When the time comes, the natural moat will become open, and pedestrians and carriages can cross the Yangtze River and the Yellow River as if walking on flat ground.”

Yang Tong's words seemed to be full of magic power, which made the blood of the civil and military ministers present excited.

The past dynasties have conquered almost all rivers, except for the Yangtze River and the Yellow River. These two rivers are like an insurmountable moat, hindering the communication between the north and the south, and troubled people from generation to generation. Together, the Sui Dynasty really has the possibility of conquering the Yangtze River and the Yellow River.

"This volcanic ash can not only be used as a water bridge, but also when the track passes through the valley. Using this method to build a track bridge will definitely achieve twice the result with half the effort. In addition, it can also build cities, houses, and embankments..." Speaking of this, Yang Tong hated iron for being weak and said to Jiang Xingben: "You clearly discovered the magic of this thing, but you said it was useless, and you didn't study it carefully. If I hadn't seen this box, such a magical thing would be like this Passed by Da Sui. I said you are useless, are you convinced?"

"I am convinced, please give me the sin." Jiang Xingben was surprised and happy, but more ashamed.

Jiang Xingben, who has a deep understanding of the characteristics of volcanic ash, realized it.

With Yang Tong's suggestion, everything suddenly became clear.

I even thought of building the bridge pier in the shape of an arrow pointing upstream, so that not only can the power of the torrent be greatly reduced, but also the things floating on the upper stream can slide through. At the same time, a dam should be built above the pier , lest the ship be wrecked...

"That's all." Yang Tong shook his head. There was no shortage of skilled craftsmen in the Sui Dynasty, but there was a lack of flexible minds and changing consciousness. This is a common social behavior. Jiang Xingben, Li Chun, He Chou, Yuwen Rutong, Yuwen Wen, etc. The master is a pretty good character.

"There is no shortage of fetishes in daily life, but a pair of eyes to discover them. In the future, we should pay more attention to everything, discover more, study more, and ask why?"

"Here."

"By the way, is there any volcanic ash and volcanic rocks in Daxing City?" Yang Tong asked.

"There is in the imperial city!" Jiang Xingben explained: "The track uses the technology of flicking soil from craftsmen in the Western Regions, and there is volcanic ash in it. In order to further improve the Qihe soil, we took a lot of volcanic ash from the Ministry of Industry to the official residence for testing. "

Fushi is Rome, and it is also an ancient country with a long history. They are different from the Central Plains, which is mainly made of wood, in terms of architecture. They are used to repairing the walls of houses and walls with stones, so their use and understanding of soil is far superior to that of the Central Plains.

The most advanced concrete in Rome is heptadite, which is a mixture of seven types of soil, and it is very strong.It is several grades stronger than the rammed earth and composite soil used in the Central Plains.The recipe for the ratio of Qihe soil was also spread to the Sui Dynasty with the arrival of craftsmen from the Western Regions.

"Go and try the volcanic mud effect." Yang Tong walked out of the hall first.

Everyone was curious when they heard Yang Tong speak so miraculously about the volcanic ash. Seeing Yang Tong make a move, they followed him in a mighty manner and rushed towards the mansion of the Ministry of Industry.

In the mansion, Li Chun, the minister of the Ministry of Industry, was staring at a model of a cable bridge with three intersecting semicircles on each side. This model was Yang Tong’s idea for building a bridge across the Yellow River. He thought it was very feasible, but how to stabilize the three intersecting bridges? The arch bridge really stumped him, and when he heard about the efficacy of the volcanic ash, he followed him excitedly to the backyard.

There are many craftsmen here. Under the command of Yang Tong, everyone first made a rectangular mold, like pouring upside down, and laid a layer of thumb-sized iron bars in the middle of the mold.

After the mold was made, the mixture, slaked lime, sand, and volcanic ash began to be stirred.

Craftsmen have long been familiar with the simple task of mixing mortar.

Of course, it is the first time to use volcanic ash as the main ingredient. Before that, it was mixed with slaked lime, glutinous rice slurry, clay and other sundries.

This kind of glutinous rice mud is one of the oldest crafts. The Qin Great Wall can survive for a thousand years because of this craft.

The stirring of volcanic mud is no different from that of glutinous rice mud.

After mixing evenly, the craftsman poured it into the mold and flattened it with a smooth wooden board.Then according to Yang Tong's instructions, spread the remaining volcanic mud on a flat bluestone slab, like a brick wall, and build a small wall from the ground.

When they had completed these two tasks, they found that the volcanic ash, a mixture of lime and water, began to harden very quickly.

No one has ever seen this hardening speed.

Everyone was dumbfounded.

Jiang Xingben was shocked and said: "It only took about a moment, and the mud dries up a lot, which is unbelievably fast." He also pushed the stone wall hard, and the countless bluestone walls mixed with mud did not move at all. .

"It's just that the surface is dry, and it will take several hours for the mud mixed between the bluestones to harden. When it is completely hardened, it will become one with the bluestone, and the clay tablet with iron as its bone and mud as its muscle will be even more powerful." , as solid as a rock, hard to be wounded by a sword, harder than a solid boulder."

Jiang Xingben has already seen how powerful this thing is, and it can't be pushed even before it's completely hardened. No matter how dry it is, water will seep in. If it is used to repair bridge piers, wouldn’t the seeped water be washed away?”

"You still haven't found the correct way to use it." Yang Tong shook his head: "Because it requires a lot of water to blend, so when you repair bridge piers, you only need to pour dry slurry, and the infiltrated water will Not only can it not be washed away, but it will become its tonic. When the water volume exceeds its absorption capacity, it has hardened, and by then, the weak seepage water can no longer wash it away.”

"Yes!" Jiang Xingben's eyes lit up, and he said excitedly: "As the Holy Majesty said before, as long as we isolate the water of the Yellow River, clear the rock bottom, drill holes, and nail iron bars in this waterless area, Then pour the unwatered mortar into it, and the iron bar will be firmly fixed to the bottom of the river. Afterwards, on the base, use wooden planks to form a bridge pier, pour in the dry mortar, and then water the place above the water level. Pulp."

"That's right." Yang Tong pointed to the drying cement slab and said, "The bridge pier is completed, and if this kind of cement slab is laid, it will be a smooth bridge deck."

"With this fetish in hand, the Yellow River Bridge can be expected." Li Chun beside him said happily.

"Although there is cement that can harden in water, we can't lay down bridge piers all over the river because of the convenience of water, otherwise, there will be countless "mainstays" in the Yellow River, which will make the Yellow River lose its ability to transport water, and the loss is worse than that without crossing. River bridges are infinitely larger, so before building a bridge, the distance between the piers, the height of the bridge deck, and the size and height of the boats must be considered, and compared to plane bridges, I think cable-stayed bridges may be more suitable."

Yang Tong pondered for a while, and said to Li Chun: "In order to verify the feasibility of the cable-stayed bridge, Li Shilang, please take a group of bridge craftsmen to Luoshui to try to build one, so as to accumulate experience for the future Yellow River Bridge, and also for our great Sui Dynasty. Cultivate bridge talents."

Li Chun took a deep breath, suppressing the excitement in his heart, "I will never fail my sage to build a cable bridge."

"Just do it according to your own design plan, don't be afraid of failure, if you fail once, you can make ten times, if you fail ten times, you can make it a hundred times." Yang Tong encouraged.

"Thank you for your trust."

Li Chun was surprised, delighted and moved!

Yang Tong gave him this opportunity, this credit is too great, once he succeeds, then his name Li Chun will be immortalized forever.

What he didn't know was that the completed Anji Stone Arch Bridge was enough to make him famous in history.However, if the Yellow River Bridge was completed in his hands, the achievements of Anji Bridge would be almost negligible.
