Defend the Tang Dynasty

Chapter 79 Technical Barriers

On the other side of Congling is Ba Tie from the previous life. He was clever and handy. In the previous life, he was able to create a military industry in the village, and now the handicraft industry is also very developed.

Black powder is not only less powerful, it is difficult to kill people, and it is too simple.

Once people know that they can imitate it in minutes, even better than you.

The same is true for matchlock guns and flintlock guns. You don't even have to think about it, and you can't get it even if you kill it.

If you want to do it, you should do high-end ones, and realize the technical barriers in one step, so that people can't learn it even standing here.

After unremitting efforts, a tower of pottery vats stacked with pottery vats and propped up by wood was erected in this valley about nine miles away from the future coking workshop six days ago.

After six days of trial operation, although the much-needed two acids were successfully refined in batches using the indigenous method, the equipment was too crude and various problems occurred.

Part of it has been solved, and some still need to be solved slowly, but refining cannot stop.

Each of the large pottery vats is made into "male and female" respectively, and the upper and lower hooks are buckled.

Holes are drilled on the cylinder, and copper pipes or pottery pipes specially fired by Sogdian merchants are used to connect them, and the joints are all sealed with mud.

Two old soldiers put the carefully selected sulfur into the huge brass box in front of the tower, and carefully ignited it, and the two Yele men who were no longer slaves hurriedly pulled the bellows.

In front of the pagoda, there is also a pottery vat containing fire nitrate. Below the vat is a fire pit. Two slaves add charcoal to the fire pit. The smoke produced by boiling nitrate in the other vat is the same as the smoke from burning sulfur. Entering the majestic refining towers layer upon layer, I don't know which tank the smoke and smoke have entered at this moment.

"Smoke is running here, stop it!"

"Old man Chen, who told you to take off the mask. The smoke is poisonous, do you want to die!"

"Fake Daoist, don't be inferior."

"Isn't it just green alum? It's not like I haven't seen it before."

The false Taoist muttered something, and hurried to the windward place.

Han Ping'an checked around the tower group, asked the craftsmen to plug up a few joints that were not sealed enough, and returned to the windward place with a lot of emotion.

With so many resources and theoretical basis, in a relatively peaceful environment, and on the premise of knowing the feats of the predecessors in the previous life, it still took more than a month to realize the batch refining of sulfuric acid and nitric acid.

It is really admirable that those seniors in the previous life groped for such a "clay pot method" when they had nothing during the war, when their safety could not be guaranteed.

The false priest didn't know what he was thinking, so he asked puzzledly: "Sanlang, what are you doing for refining so much green vitriol? Haven't you already refined several vats?"

"It's very useful, and there are many uses. It's not enough to practice it."

"How much do you plan to practice?"

"As much as you can refine, this refining tower can only be improved, and it must not stop."

"How to improve?"

"I don't know. When these students graduate, I will select a group of smart ones who are dedicated to Taoism. I will teach them well and let them concentrate on studying. In time, they will definitely come up with better refining methods."

After coming out for more than a month, I didn't see the Taoist magic weapon that can wipe out the invading enemy. A little impatient, Mr. Chen walked over and asked, "Sanlang, I know that green vitriol is poisonous, so don't you plan to throw it on fire like oil?" , stand on the top of the city and defend the enemy with green vitriol."

"Of course not, let's go, I'll take you to have a look."

……

Han Pingan led the two of them on horseback for more than twenty miles, and came to a small stream deep in the valley.

Li Chengye personally garrisoned here, the fake Taoist priest and Yichang Chen have never been here, only know that the green vitriol and nitrate produced by the refinery are sent here.

Qian Chonghou also sent a lot of oil, noodles, cotton, paper, stone mills, pottery pots and other messy things here one after another.

Looking from a distance, a dozen old soldiers with their mouths and noses tightly covered were lined up, sitting in front of clay pots, moving cautiously.

There are also many old soldiers busy in the shacks farther away, and they don't know what they are doing.

"Sanlang... Yichang Chen and the false Taoist priest are also here."

Li Chengye came up to him with a smile on his face.

Han Pingan got off his horse and asked, "Uncle Six, have you done anything?"

"I made three more as you said, and tried one in the morning, and it worked!"

In the past four days, three people died and sixteen people were injured, but Li Chengye was still very excited.

Han Pingan could understand his feelings, but he was more worried about his safety, so he stopped him and asked, "Uncle Six, you tried to cast it yourself."

Li Chengye grinned: "That treasure is too expensive, and I don't want to let others let it go."

"It's too dangerous."

"It's okay, I know now, you have to handle the Perak water with care, and the thunder silver with care, and you have to be careful when baking the pili cotton and pili powder, be careful when grinding it, and even more careful when putting it away. Hide as far as you can."

"General Li, what kind of treasure is it?" Yichang Chen asked curiously.

Everything in the valley would be frightening if it was spread out. Li Chengye was very clear about what he had in hand, so he didn't answer his question, and subconsciously looked at his son-in-law.

"Sixth Uncle, put one in to open Yichang Chen's horizons."

"Okay, I'll get it, so don't go in."

Li Chengye valued everything in the valley above his life, and he didn't want the false Taoist priest and Chen Yi to advance, so he asked his subordinates to stare first, and ran in to bring a stone pot with a long cotton thread on the spout.

"Sanlang, that's it?" Yichang Chen asked dumbfounded.

"This is just a sample mine. The mine powder inside is not stable enough, so we need to keep exploring. When a better and more stable one is trial-produced, then we can cast a lighter grenade, and throw it out to wipe out the invading enemy."

"Really?"

"Whether it's true or not, you'll know later."

Li Chengye was bold and felt that he was the only one qualified to cast this treasure.

He brought the three of them to a small hill full of gravel, and asked Han Pingan and the others to hide behind a boulder, and walked over alone to gently put Shi Lei into the pile of rubble.

Immediately, he untied the hemp rope around his waist, carefully tied the cotton thread on the stone mine, and stepped back while putting the rope until he was behind the boulder.

"Sanlang, I let you go?"

"Let it go."

Han Ping'an subconsciously moved inside, plugging his ears with his fingers.

Yichang Chen and the fake Taoist priest hurriedly covered their ears under his signal, but they wanted to see clearly, so they couldn't help poking their heads out.

It was far enough away from the explosion point, and Han Ping'an was thinking that they would not be accidentally injured, when he heard a loud bang, like a thunderbolt from the blue sky, deafening, and rocks flying.

When the air wave hit, Yichang Chen was caught off guard and sat down on the ground.

The false priest's ears were buzzing, he saw Li Chengye's mouth moving, but he couldn't hear what he was saying to Han Sanlang.

Although he was mentally prepared and believed in his heart that Han Sanlang could do it, he was still stunned by the sudden thunder.

Yichang Chen couldn't hear it either, so he put his hands on the ground and watched Han Sanlang and Li Chengye foolishly watching the explosion effect together.

"This one is made with pili oil, yesterday's one only had pili powder."

"How much did you add?"

"You asked me to add four drops, so I asked them to add four drops. I dare not add more."

"The power is greater than without it."

"It's not just bigger, it's bigger than nothing. Look, all the rocks that exploded flew over there."

Add nitrated starch, nitrated cotton, and some nitroglycerin, and detonate it with the thunder silver detonator invented by the predecessors in the previous life. The power seems to be okay.

Han Ping'an didn't know if it belonged to Shuangji or not. He only knew that at this stage, he could only improve slowly on this basis, and that there might be room for further improvement when the coking workshop was built.

"With this baby, do we need to be afraid of Tubo? Do we need to be afraid of Dashi? When I gradually try to make a better one, I will definitely go to the west of Congling like my ancestors did, and take back the Persian Protectorate!"

Li Chengye felt that this was already against the sky. He leaned over to pick up a piece of gravel, greedily smelled the smell of the explosion, and clenched his fists passionately.

Han Pingan looked around and said, "There must be a chance to regain the river, but we are too small to regain it."

Li Chengye was afraid that he would not have the chance to lead his troops across Congling and gallop across the river in his lifetime, so he said in an almost pleading tone: "Hurry up, sixth uncle will be 43 this year, God knows if he will live to the age of Lin Shijun."

"Relax, up to 15 years."

"15 years is too long, how about ten years?"

"Sixth Uncle, as long as you don't always take the lead, you will surely live to the age of Mr. Lin, and I will definitely let you lead the army to march west."

"I want to be the coach!"

"You are the marching commander of my Yele Metropolitan Governor's Mansion. If you are not allowed to be the commander-in-chief, who will be the commander-in-chief? The unrivaled achievement of regaining the Persian Metropolitan Protectorate is none other than you. No one else can take it away even if they want to."

"Don't let An Fuyan know what's going on here."

"It's natural, let him know how we can regain the Persian Capital Protectorate."

The false Taoist priest is still immersed in the shock brought by the great supernatural power of Taoism. He obviously doesn't believe in those Taoist treasures, but only believes in the three ways of mathematics, physics and chemistry, and he still can't help reciting mantras.

Yichang Chen got up, stumbled over, looked at the crater left by the explosion, and was incoherent with excitement.

"Thunder on the flat ground, Taoist supernatural powers are really unfathomable, Sanlang, avenge me, avenge my five hundred sons..."

Han Pingan could understand his mood at this moment, supported him and asked, "Why don't you take the Maza Tata first and charge some interest first?"

20 years ago, the Tubo army committed Yele, and the Maza tribe was the striker.

Chen Yichang had hated the Mazha tribe for a long time, and said excitedly: "Okay, let's go to the front of the house first."

The Mazha tribe is as isolated as Yele Town. If Mazha Tata wanted to visit their Zanpu, they had to go around from the west of Congling Mountain or from the right side of Longlong, because directly to the south is the uninhabited land of thousands of miles of high cold.

In fact, from the moment Wutumu went to Baisha City to threaten, Han Pingan made up his mind to clean up the Mazha department. After all, eating persimmons is of course picky.

Exploding stones is not as interesting as exploding Tubo. Besides, when such a powerful thunderbolt comes out, it must be sacrificed to heaven.

Li Chengye felt that he could sacrifice the Mazhabu to heaven first, so he couldn't help asking, "When will we do it?"
