After Wei Zheng finished his question, he waited for Fang Yiai's answer.

Li Shimin and a group of ministers also stared at Fang Yiai and waited for him to give an explanation.

The same is true for Cheng Chumo and Changsun Chong. They trust Fang Yiai unconditionally. They went to report the news without asking in detail before. Now they talk about it, and they are very curious about the reasons.

Fang Yiai was a little overwhelmed for a moment. He just reminded him out of kindness, but he didn't expect to be questioned.

How did he answer this? Tell them about the popularization of knowledge such as bacteria, activity, and temperature... Don't be funny! I'm afraid I will be treated as crazy words. The more I explain, the more I can't explain it, and I will be punished for deceiving the emperor.

"You always get such a serious crime, so scared that the boy dares not say anything."

"Who doesn't know, you are so brave! Will you be scared by me for a few words? Stop talking nonsense, why do you do this?" Fang Yiai wanted to change the topic, but was exposed by Wei Zheng ruthlessly.

"You are a great husband, how can you not be afraid..."

Fang Yi Ai talked about him, and Wei Zheng was no longer talking to him. He just looked at him and waited for him to give an explanation.

"Drinking raw water makes you sick easily, you should know?" Fang Yiai asked back.

"good."

Wei Zheng nodded and admitted, Fang Yiai continued, "That's because the raw water is full of small insects that are invisible to the naked eye, so it is easy to get sick after drinking it. The ice in the palace was chiseled from the river. The ice is made of boiling water, and all the insects are killed, so that they can only be eaten."

"The ice is so cold, and some insects have long been killed."

"Also, you didn't say that the bug is hard to tell with the naked eye, how did you know?"

He is worthy of being a big boss in the court. He immediately seized the loophole. Several people's mouths were like machine guns, and the problem was thrown back.

"This kind of insect cannot die of freezing. Like snakes, it will hibernate in winter. Once the ice melts, it will be resurrected." He was mentally prepared for these questions and answered one by one.

"As for how the boy sees it... since the human eye cannot tell, of course he has used the tools."

"What tool is it?"

“Not in this world.”

"Boy, don't be foolish! There's nothing, do you think you can convince everyone with just one mouth?"

Several civil servants asked each other...

Li Tai was very excited when he heard this and was completely impressed by science. No matter how many people were talking, he asked: "Master, is this science too?... Can that tool be made?"

Fang Yiai taught him, "This is of course science. When manpower is in poverty, we have to use tools, which is the principle of science."

"That tool is called 'microscopy'. It's a principle you will learn in the future. It will take a little effort to do it. If you have the chance in the future, I will make one for you."

"Okay, thank you Master."

Cheng Yaojin trusted Fang Yiai more. His focus was different from those people. He asked: "Boy, can you make ice in summer?"

"What's the difficulty of making ice? Uncle Cheng, don't worry, Cheng's ice is provided by the boy, so you can't eat it."

"Hahaha, OK, I'll leave it to you in the future."

Seeing Fang Yiai was serious, everyone was sure to be a little scared.

After Cheng Yaojin interrupted, the topic turned to ice making. In the hot summer, it was really amazing to be able to make ice, and everyone stared at him again.

Li Shimin couldn't help but be curious and asked, "Is the ice really made?"

"yes."

“How can I make ice in summer?”

"I will hand over the ice making method to Your Majesty later."

"So mysterious, I'm afraid I won't be able to learn your secret recipe?" Cheng Yaojin and others immediately became unhappy when they saw this.

"The uncles and uncles misunderstood, so everyone can't do anything. From now on, the house will be free to use ice. What do you think?"

"Okay, you guys have a little conscience."

While talking, they had already arrived at the slum...

"Please, Your Majesty."

Fang Wenquan led everyone to the yard where the cement was boiling. As soon as he arrived at the door, he saw the cement wall with several hammer marks on it.

Several generals rushed over first, pinched the hammer mark and turned into debris, and said in surprise: "It's really like a stubborn stone."

"If the city wall was cast with this cement, it would not be inferior to the current city wall, and the construction method was extremely simple, so it would not take many people to achieve twice the result with half the effort."

"The road built with this object is like paving a stone slab. It will not be affected by rainy days, and the speed of transporting grain and grass will be greatly improved."

He is worthy of being a veteran in the army, and this has begun to discuss the military uses of cement.

"I'll try it, how strong this guy is."

Yuchi Gong said, carrying the hammer and walked forward, and everyone made way. "Bao, bah! Ah..." On the side of the wall, Yuchi Gong spitted into the palm of his hand and waved the hammer and smashed it on.

As a result, like Cheng Chumo, he was shocked and retreated repeatedly. In order to regain his face, his veins swelled up and made a crazy output, and he had to smash the wall.

"Your Majesty, this cement is of great use to the court and requires large-scale production of cement."

Li Jing also bowed and said, "I beg your Majesty to change the official roads of the world into such cement roads, and the speed of food and grass supply will be increased several times."

"Don't worry, I will think about it seriously."

As the lord of a country, Li Shimin was different from Li Jing. Li Jing was just a pure soldier. He had to take overall charge and consider all aspects of gains and losses.

However, Li Shimin was quite happy to get such a strange thing and looked at Fang Yiai on the side, "This kid can always surprise me."

Seeing Li Shimin coming, Fang Yiai knew the current affairs very well, "I will send the method of firing cement to the palace."

He understood the importance of cement in engineering construction, and knew that he could not be completely controlled by himself, and had been mentally prepared and had nothing to worry about.

"Cement is of great use to the court, and Fang Yiai You make an indelible contribution."

Li Shimin was quite pleased to see Fang Yiai so tactful, and then said: "The man in Xinfeng County has repeatedly made great contributions to the country. He is hereby granted it to Xinfeng County. From then on, you will be fully responsible for the cement firing."

"Thank you, Your Majesty."

After hearing Li Shimin put a burden on himself again, Fang Yiai agreed with a bitter face. He also understood Lao Li's temper and would not agree to resign. There was no need to do this in one go.

The emperor doesn't want to be faced?

Afterwards, Li Shimin took the cement formula and took a group of ministers and left happily.

"Congratulations to Fang Er."

When Li Shimin and others walked back, Changsun Chong and Cheng Chumo came up to congratulate him, but Fang Yiai was depressed and everyone got used to it.

"Seeing you're a coward, you're not happy after being promoted. Others don't know about it, and they think you're drowning."

After a few people had a good time, they started to recover.

...

Soon, the strange thing that Fang Yiai made ice in summer spread in Chang'an City, and the people were amazed at it.

Behind this, a huge wave of malice was pouring towards him.
