Guide to Traveling through the Northern Song Dynasty.

Chapter 1196 Epilogue : This Love Can Be Turned into Cement
Another month and a half passed, Luoyang Imperial College was on summer vacation, but Xie Yan was still doing cement preparation experiments.

The overall idea remains unchanged, and it is necessary to constantly adjust the structure of the cement kiln, constantly adjust the spatial proportion of each layer of the fired material, and constantly change the combination of raw materials, mineralizers and retarders.

A lot of things are added, including gypsum, fluorite, slag, sandstone, coal gangue, iron ore and so on.

These things do not need to be thrown in completely, but are determined by the local limestone and clay composition of the cement plant. Xie Yan cannot test the specific composition, so he can only use the stupid method - trial and error.

Even if he doesn't apply for a patent, Xie Yan is not afraid that his cement will be surpassed by others. Because the raw material composition in different places is different, the auxiliary materials that need to be added must also change accordingly. The quality of his cement will always be the best!

Of course, it doesn’t have to be so complicated. Just adding two or three basic auxiliary materials will be enough, and the quality will definitely be better than the existing cement in Daming Dynasty.

When authorizing patents to others, Xie Yan can also do this and only provide basic processes and formulas.

If you want the advanced version, you have to pay extra. Invite Mr. Xie to go to the relevant factory to do experiments in person, and then increase the auxiliary material formula according to the local raw material ingredients.

"Mr. Li, please give it a try." Xie Yan said with a smile.

For a poor noble like Li Minqiu, it would be enough to call him "Mr. Li", but Xie Yan always called him "Mr. Li". This made Li Minqiu happy and often felt that the young scholar Xie was reasonable.

The original meaning of "Yuanwai" was to add an additional official. During the Tang and Song dynasties, all idle officials who were bought with money could be called "Yuanwai + a certain position". Gradually, the wealthy gentry who had money but no power were uniformly called "Yuanwai" when they needed a respectful title.

"Xianggong" is almost the same. It was originally a respectful title for the prime minister, but now anyone can call him Xianggong.

The essence is the same as Mr. Zhang, Mr. Li, Mr. Wang, and Master Sun.

Li Minqiu personally picked up a hammer and walked towards two brick walls that had been left for many days. One was built with Li's cement, and the other was built with Xie Yan's new cement.

"Bang bang bang!"

Li Minqiu picked up the hammer and started smashing.

The brick wall was not thick. After only three hammer blows, obvious cracks appeared between the joints of the wall built with Li's cement.

He hammered at the new cement wall again, bang ...

Li Minqiu praised: "Good cement!"

Xie Yan said: "Please try the condensed stone over there again."

"Ningshi" is the name given to concrete by the Ming people, and iron bars and various hard stones have been added to it. But they only added wrought iron bars, not the luxury of adding steel bars.

Li Minqiu's arms were sore from swinging the hammer a few times, so he asked two farmers to come over and smash the two thin concrete pillars with hammers.

After a lot of hammering, the two concrete columns were completely broken, leaving only the iron bars inside still connected.

But one of the columns had a lot of holes on its surface, especially in the place where it was subjected to repeated stress, and was even smashed by the farmer's hammer.

The other concrete column, after being forcibly broken, had a much shallower and smaller pit at the stress point. It took several more hits to break.

"It's amazing!"

Li Minqiu squatted there and observed carefully, marveling at the sight.

After a long while, he turned around and walked in front of Xie Yan, bowed and said: "Mr. Xie is a scholar of heaven and earth, I admire you very much!"

Xie Yan smiled and said, "Thank you Mr. Li for lending me the land and craftsmen, and for helping me buy a lot of test materials. Once I get the patent for cement, I will authorize the Li family to use the patent for free for ten years."

Li Minqiu subconsciously wanted to pretend to refuse, but was afraid of making things worse, so he bowed again and said, "Please don't pay me rent, Master Xie. I can stay here as long as I want. Of course, this little rent is not enough to repay Master Xie's kindness. From now on, if Master Xie sends me any orders, the Li family of Luoyang will never frown!"

"No problem." Xie Yan bowed.

The next day, Xie Yan took the patent application materials to the patent office of Luoyang Prefecture Gongcao.

When he heard that it was Mr. Xie who had come, Gong Caoyuan came to receive him personally and said to the patent examiner, "Examine and pass it as soon as possible, and don't delay Mr. Xie's time."

After saying that, Gongcaoyuan took Xie Yan to have tea.

Before I finished my tea, the patent examiner came running over and whispered, "Yuanshi, Xie Xueshi has improved the cement, and he claims that its quality is far superior to the past. If you add steel bars and gravel, it can even be used to build flood control dams."

The reason why the existing cement in the Ming Dynasty was difficult to use to build dams was that, in addition to its insufficient strength, it also lacked water resistance and corrosion resistance.

"puff!"

The clerk spat out a mouthful of tea and quickly snatched the patent application materials.

The Gongcaoyuan of Luoyang Prefecture is equivalent to the director of the Industrial and Commercial Bureau of the capital Luoyang. It has now become an unspoken rule that Gongcaoyuan is basically held by Jinshi of science.

Xie Yan hid key information such as the details of the vertical kiln and the ratio of raw materials in the patent application materials. After reading the materials, Gong Caoyuan asked, "Is this true?"

Xie Yan replied: "If you don't believe me, you can go to the cement factory of Li Yuanwai in the southern suburbs. There you can see brick walls made of new cement and cast concrete stones."

The Gongcaoyuan immediately said, "Please ask Mr. Xie to lead the way."

"Leaving now?" the patent examiner asked hurriedly.

The Gong Caoyuan rebuked: "Of course the sooner the better. Do you know how useful this cement is? Since it can be used to build flood control dams, it can also be used to build castles on the border!"

The subtext is that although we didn't invent this shit, it is definitely a great achievement that we were able to get our hands on it and report it quickly.

Why are you just standing there if you don't want to take advantage of the merit? Gongcaoyuan immediately took the patent examiner and several of his subordinates and ran towards the southern suburbs in a hurry.

After witnessing the performance of the new cement with their own eyes, the engineering team rushed back and immediately issued a patent certificate to Xie Yan, and then quickly reported it to the prefect of Luoyang.

The prefect of Luoyang reported the matter to the imperial court.

……

Princess No.

Zhu Tangxi is painting in front of a pond full of lotus flowers, which have been in full bloom in recent days.

"Your Highness, Your Highness, Xie Liulang is here!" a maid ran over to report.

Zhu Tangxi said happily: "Please come in quickly."

Xie Yan became more and more familiar with the layout of the princess's house. Not only did he not need a guide to come in from the outer courtyard, even the inner courtyard and gardens were just like home.

He heard that the princess was by the lotus pond, so he walked a long way over there.

Zhu Tangxi pretended to continue painting the lotus. He seemed to be concentrating, but in fact his attention was completely distracted, and the only thing in his mind was the sound of footsteps getting closer and closer.

"How come you are free today?" Zhu Tangxi asked with a hint of resentment in his tone.

This little rascal is so heartless. Ever since he gave me a necklace last time, he hasn't come to my house on his own initiative in the past forty days.

Zhu Tangxi was so angry that she stopped contacting him, waiting for Xie Yan to come over to apologize and coax her. But after waiting for so long, Zhu Tangxi couldn't stand it anymore and took a carriage to visit the Longmen Grottoes.

She insisted that she was going to the Longmen Grottoes and stopped by to see the progress of Xie Yan's experiment.

Every time Zhu Tangxi went to the southern suburbs, she was coaxed into a good time by a bunch of earthy love talks, and happily went home to wait for the next time. She waited and waited but Xie Yan didn't come, so she was so angry that she had to take the initiative to leave the city again.

After going there four times in a row, she became familiar with all the Buddhas in Longmen Grottoes.

Xie Yan knew he was in the wrong, so he quickly sat down beside the princess, took her hand and said, "Sister, your lotus painting is so beautiful, so lifelike."

Zhu Tangxi wanted to lose his temper, but he failed to pull his hand back after pulling it twice, so he said angrily: "The first time you came, you wanted to cooperate with me to set up a cement factory. The second time you came, you asked me to write a recommendation letter to the Ministry of Industry to check information. The third time you came, you asked me to help borrow a microscope. The fourth time, we went to the city together to look for fluorite. You are a person who does things without benefits, what do you want this time?"

Xie Yan was stunned when he heard this.

It seemed that it was just as the princess said, that every time he visited her, he had a purpose. Scumbag!
This kind of thing definitely cannot be admitted. Xie Yan said with a smile: "Sister, you remember it very clearly. Did you recall every time we met in detail?"

"I don't have the time for that," Zhu Tangxi asked in a disdainful tone, "Tell me, what do you want this time?"

Xie Yan looked aggrieved: "Sister, do you really think I'm such a utilitarian person?"

Zhu Tangxi asked back: "Aren't you?"

Xie Yan took out the cement patent certificate and asked, "Sister, look what this is?"

Zhu Tangxi glanced at the cover and asked in surprise, "Is the cement made?" Then he complained, "I helped you run around, but I found out later than the officials in the Ministry of Works."

"Isn't this a surprise for you?" Xie Yan moved closer and closer, his mouth almost touching the princess's ear, "Look, what is this cement called?"

Zhu Tangxi's ears were itchy from the heat, and his resentment had subsided by a third. He looked at the name of the invention patent and instantly smiled: "You still have some conscience."

Xie Yan named this cement "Qin Cement."

This naturally originated from Zhu Tangxi's title: the Grand Princess of Qin.

"In the future, the entire Ming Dynasty, and even the entire world, will use Qin cement. Everyone who lives in a house built with Qin cement will know that this is a gift from me to my sister," Xie Yan asked, "Do you like this gift, sister?"

"Yeah." Zhu Tangxi responded softly, his tone became particularly gentle, staring at the patent certificate again and again.

Qingluan was standing nearby, and was also deeply moved when she heard Xie Yan's words. This love and this feeling, spread all over the world, truly known to the whole world. Alas, I wish I were a princess, why don't men treat me like this?

Zhu Tangxi put down the patent certificate and asked all the maids to leave.

Then he said affectionately: "I have learned how to make a kind of pastry. Can I make it for you today?"

"Okay." Xie Yan held the princess's hand and took the opportunity to kiss the back of her hand.

Zhu Tangxi did not resist, but peeked in the direction where the maids left. Seeing that there was no one around, she lowered her head and kissed Xie Yan's cheek.

She originally wanted to just kiss her and stop there, but she ended up making the man so excited that Xie Yan simply hugged her in his arms.

Zhu Tangxi just felt her whole body getting hot and her body softened a little, so she just closed her eyes and let him hold her.

But the little rascal was still not satisfied and actually found her lips and kissed her.

The princess suddenly opened her eyes, resisted twice, and quickly closed her eyes again.

Qingluan and several maids hid behind the rockery and peeked, whispering: "Kissing, kissing, how embarrassing in broad daylight!"
