Longyang loves Qin

Lao Ai was finally promoted to Marquis Che, and got the fief of Sanyang.But the Queen Mother Zhao did not convey Yingzheng's words to Lai Ai completely, so Lai Ai didn't know that this might be his only fiefdom.Although he was not satisfied with the result, as soon as he saw Lu Buwei's appearance, he felt complacent.

After becoming the Marquis of Che, Lai Ai would not live in the palace for a long time, he moved into his own Marquis's mansion, and imitated Lu Buwei's way to attract followers.However, compared to Lu Buwei's talented literati who can give advice and solve problems, most of his subordinates are flatterers, cock-calling and dog-thieves, or just foolish people, so even though the faction currently looking at him is Hao Gathered in a mighty way, but in fact it can't make a big difference.

Although Lao Ai, who has a title but no power, is greedy and ambitious now, she has not become so arrogant that she will call herself Yingzheng's "false father" in the future, so he is not here to provoke Ye Yu, a real power. Senior officials.

However, even if he wanted to provoke him, it would be difficult to find someone, because Ye Yu was taking advantage of the recent infrequent fighting, and plunged into his backyard.

Of course, there are no beautiful and intoxicating concubines in his backyard, only the messy concrete forest.

It's just that outsiders don't know. They saw so many craftsmen coming in and out of the General's Mansion, and Ye Yu seemed to stay behind closed doors. They couldn't help thinking about it, and rumors spread that "the General built a house to hide the beauty". .

Zhao Cheng immediately told Ye Rumor Body Yu about this.

Ye Yu rubbed his temples, thought for a moment and replied, "Don't worry about it."

It's just gossip, and it doesn't hurt or itch, and it will disappear after a while. If you explain something for this trivial matter, it will be counterproductive if you don't keep it clean.Besides, he's a big man, so it's good to spread some gossip, if everyone in the future knows that he is a virgin, it would be too embarrassing!

After thinking about it, he has already made up the records of later generations.

"Ye Yu is also from Wei Daliang. Ye's name is Yu, and his character is long...not feminine..."

In view of the experience of almost becoming "Longyang Jun", the words "not close to women" are not good for him.

Thinking of this, he was even more relieved, and continued to plunge into his own research.

The cement products made recently look almost the same as the ones he saw in his previous life, but they have not been tested. After confirming that they are available, they will test the effect of concrete mixed with aggregates. After all, cement is only a cementitious material. If you want to build a city wall, it is useless to use only brick walls, but to look at concrete.

A few days later, Zhao Cheng said to Ye Yu who was observing the cement test block: "The king is here."

Ye Yu looked at the dusty clothes on his body, and while thinking about the reason for Ying Zheng's visit, he went back to the room and changed into clean clothes.

Ying Zheng had no expression on his face, but Ye Yu felt that he seemed not in a happy mood.

"I'm late." Ye Yu saluted him.

Ying Zheng looked at him and asked with interest, "I heard that Aiqing is pregnant..." He seemed to combine the reason for Ye Yu's late arrival with the rumor.

Ye Yu smiled and said: "Where is there any beauty? It's rumored outside, why, it's all spread to the palace?" He didn't go to meet friends these few days, and he thought that the rumors had almost died down, but he didn't expect it to intensify. To the point where even Ying Zheng in the palace knew about it.

Ying Zheng withdrew his appreciative gaze, and replied, "You've been in the mansion all this time, I'm afraid Qing Gan and the others will believe it."

Ye Yu calculated in his heart, except for Shangchao and on-duty, it seemed that he hadn't gone out for several days, and even Shangxiachao was in a hurry because of the recent breakthrough.

"The minister is just studying something." He said truthfully.

The cement has almost been developed, even if the concrete can't be produced for a while, the usefulness of the cement is not small, so Ye Yu also has some confidence to talk to Ying Zheng.

"Research?" Ying Zheng looked at Ye Yu suspiciously, "It's... what's wrong with the art of war?"

"It's cement." Ye Yu explained the efficacy of cement.

Ying Zheng didn't react much at first, but when he heard it, he sat up straight involuntarily.

After talking about the efficacy of cement, Ye Yu suddenly remembered his dark history, and hurriedly added: "The cement minister has already developed it, and the concrete is being made."

Hearing that he was talking eloquently just now, Ying Zheng suddenly became a little eager, thinking of the incident back then, he couldn't help but smile.

The object of black history was right in front of him, and he still remembered that even though Ye Yu had become calmer and calmer, he still felt his face was a little hot at this moment, not to mention that Ying Zheng's mouth was slightly raised, and he pursed his lips and chuckled lightly, with a sense of humor.

He immediately coughed lightly to hide his unease, "I will take you to see the finished cement product."

Ying Zheng didn't tease him, and followed him to the backyard with a straight expression.

Seeing the forest of stones, Ying Zheng was slightly shocked, "Is this cement?"

Ye Yu nodded, and led Ying Zheng inside, "Most of these are previous failures."

After walking for a while, he pointed to an orderly row of stone cubes on the ground and said, "These are the latest batch, and the effect is also the best."

Ying Zheng knelt down and touched it, then picked up one and looked at it carefully for a while, completely ignoring his dust.

"If this thing and that concrete are as Aiqing said, our Great Qin City Wall must be unbreakable!" His eyes seemed to be shining brightly.

Ye Yu nodded, "It's just that you have to think carefully. You have to be able to withstand the wind, the water, the cold, and the heat. I'm still testing this subject."

Ying Zheng got up, looked forward and found a room with locked doors and windows, he asked, "What is that for? Is it also related to this cement?"

Ye Yu stepped forward quickly and asked Ying Zheng to wait for a while. He took out the key and opened the door, and suddenly a puff of smoke came out from inside.

After a while, Ye Yu signaled Ying Zheng to come forward, "This is the state of the cement when I test the severe heat."

Ying Zheng saw several braziers at the door, and felt even more stuffy when he walked in. He wiped off the sweat that hadn't come out of his forehead, and felt a little choked. He covered his mouth and nose and looked at the cement not far from the braziers. , found that it was no different from the outside before walking out satisfied.

Before turning around, he suddenly noticed a shelf not far away, with a few pieces of pork hanging on it.

When Ying Zheng walked out of the room, he asked about it.

Ye Yu's eyes drifted away, and he said a little embarrassedly, "I see the smoke is big...just try to use smoked meat by the way."

There was no bacon in the pre-Qin period, but Ying Zheng could guess that it was this kind of delicacy, and shook his head helplessly, but didn't say anything to him.

Ye Yu was a little embarrassed, so he quickly changed the topic back to the right way: "We have tested the great heat and water, and the strong wind and cold can't be detected for a while. We have to wait until winter or... ice?"

Ye Yu suddenly thought of something, he hadn't seen how to make cement in time travel novels, but he talked about how to make ice!

Saltpeter to make ice!

It's just such a simple four words, he doesn't even need to elaborate, he still remembers this bit of chemistry knowledge.

He was about to tell Ying Zheng about this, but he stopped suddenly.

He has never seen what a native saltpeter mine looks like, and there is no gunpowder in this era. There should not be many people who know saltpeter. How should he find it?

"Ai Qing?" Ying Zheng noticed that Ye Yu seemed to have thought of something just now, his face was surprised at first, but then he frowned in thought.

Ye Yu didn't have time to reply to him, because he felt that he was a little familiar with Nitrate, and it didn't come from the memory of his previous life.

Nitrate, nitrate, nitrate... where the hell is it...

He didn't dare to interrupt his train of thought, trying hard to remember.

——If the eyes are blurred, melt the Northern Emperor Xuanzhu and add red pill...

He remembered!

When the imperial physician was teaching him, he once mentioned a medicine called Beidi Xuanzhu. He was curious about the name and asked a lot, and later found out that it was nitrate.

"Northern Emperor Xuanzhu!" He looked at Ying Zheng and said, "Northern Emperor Xuanzhu can make ice."

Ying Zheng was surprised, "Is what you said true?"

"I have to try it out." Ye Yu said cautiously.

Yingzheng immediately sent someone to find Beidi Xuanzhu, and he also had a new set of clothes, because his clothes were now stained with a smoky smell, so it's okay to go to Ye Yu's mansion, but it's really not good to go back like this elegant.

While waiting for the servant to return, Ye Yu and Ying Zheng returned to the lobby.

At this moment, Ye Yu suddenly thought that Ying Zheng didn't seem to have said the purpose of coming to him, so he couldn't just come to see what he was doing, right?

"The king comes to the minister's house..."

Ying Zheng excused, "How does Ai Qing feel about Cheng Xu?"

The young master becomes a beetle?

Ye Yu showed doubts on his face, wondering if Ying Chengxu had jumped up again.

Thinking about it, it's not impossible, because Lai Ai became a Marquis not long ago, maybe Ying Chengxun felt unfair again, and couldn't bear to do something.

Thinking about Ying Chengxue's actions last time, Ye Yu thought about his words and replied: "Young Master Chengxun is a little irritable, but he is still young."

"I'm fourteen years old, so I can't be considered young." Ying Zheng, who succeeded to the throne at the age of 13, said indifferently, "As for being irritable... well, it's time to grind it out."

It sounded like Ying Zheng had made a decision, so Ye Yu didn't say much after seeing this.

Not long after, a servant brought a piece of saltpeter from the medical hall.

Ye Yu put the saltpeter into the bronze basin filled with water, and put a clay pot filled with water in the basin. After a while, the water in the pot turned to ice.

Finally, there was a one-time success. Ye Yu was slightly excited, and immediately dedicated this method to Ying Zheng, and then made some ice and sent it to test the cement.

And at the court meeting in a few days, Ye Yu also understood how Ying Zheng planned to grind Ying Chengyu's temperament.

"Ling - the envoy of Lord Chang'an to Han..."

Even though Ye Yu didn't know about this period of history, he immediately understood what Ying Zheng was thinking. He turned to look at Ying Chengyu, seeing that he didn't notice at all, and was even a little bit happy, and sighed slightly in his heart.

Sure enough, it was still a little tender.

The author has something to say: ①The imperial doctor’s formula comes from "Compendium of Materia Medica", but I think this method is very similar to that of an alchemist (adding nitrate and lead), so I just used it, please don’t worry about it.By the way, the name Beidi Xuanzhu is really cool w (so I chose this among so many aliases)
