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

Li Shimin and the ministers also stared at Fang Yiai, waiting for him to give an explanation.

Cheng Chumo and Changsun Chong are the same, they unconditionally trust Fang Yiai, and they went to report the news without asking in detail, but now that they talk about it, they are very curious about the reason.

Fang Yiai was a little big for a while, he just reminded him out of kindness, but he didn't expect to be asked to the bottom of it.

How did he answer that? Tell them about bacteria, activity, temperature, etc...... Don't be funny! I'm afraid that it will be regarded as crazy words, and the more you explain, the more you can't explain it, and you will be convicted of bullying.

"You are so guilty of such a big crime, you are so scared that the kid doesn't dare to say it."

"Who doesn't know, you kid is fat! Will you be scared by the old man's words? Stop talking nonsense, why are you doing this? Fang Yiai wanted to divert the topic, but was ruthlessly debunked by Wei Zheng.

"You are always a dignified man, how can a boy not be afraid......"

Fang Yi loved to talk about him left and right, Wei Zheng didn't talk at all, just looked at him, waiting for him to give an explanation.

"You know that drinking raw water makes you sick, right?" Fang Yiai asked rhetorically.

"Not bad."

Wei Zheng nodded in acknowledgement, and 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 when you drink it, and the ice hidden in the palace is chiseled from the river, and the kid This ice is made of boiling water, and all the insects are killed, so it can be eaten." ”

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

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

The presence was worthy of being the bigwigs of the DPRK and China, and they immediately seized the loopholes, and several people mouthed like machine guns, and the problem was thrown back.

"This insect can't freeze to death, like snakes, it hibernates in winter, and once the ice melts, it will come back to life." For these questions, he was mentally prepared and answered them one by one.

"As for how the kid sees...... Since the human eye cannot argue, of course with the help of tools. ”

"What kind of tool?"

"There is no such thing in this world."

"Boy, don't be a fool! Nothing, you think you can convince everyone with just one mouth? ”

A few civil officials, you ask me word by word......

Li Tai was very excited when he heard this, and was completely impressed by science, no matter how many people were noisy, he asked, "Master, this is also science?" …… Can that tool do it? ”

Fang Yiai gave him a lesson, "Of course, this belongs to science. When manpower is poor, it is necessary to use tools, which is a scientific principle. ”

"That kind of tool is called 'microscope', the principle of which you will learn later, it will take a little effort to do, and I will have the opportunity to make one for you in the future."

"Okay, thank you, Master."

Cheng Yanjin trusts Fang Yiai more, and his focus is different from those people, and asks: "Boy, can you make ice in the summer?" ”

"What's so hard about making ice! Uncle Cheng, rest assured, the ice in Cheng's Mansion is provided by the kid to ensure that you will not eat badly. ”

"Hahaha, okay, I'll leave it to you from now on."

Seeing that Fang Yi's love was wrong, everyone was sure to be a little bluffed.

As soon as the journey bit the gold, the topic also turned to ice-making, in the hot summer, being able to make ice is really amazing, and everyone stared at him again.

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

"Yes."

"How do you make ice in the summer?"

"The minister will hand over the method of making ice to His Majesty later."

"It's so mysterious, I'm afraid I won't be able to learn your secret recipe later?" When Cheng Yanjin and the others saw this, they were immediately unhappy.

"A few uncles and uncles have misunderstood, so we don't have to do it, from now on, the ice will be used in the house, and it will be given free by the kid, what do you think?"

"Okay, you kid has a little conscience."

While talking, the group of them had already arrived at the compound......

"Your Majesty, please."

Fang Wenquan led everyone to the courtyard where the cement was burned. As soon as I arrived at the door, I saw the concrete wall, on which there were several obvious hammer marks.

Several generals rushed over first, pinching the hammer mark and turning it into crumbs, and said with a surprised expression: "It's really like a stubborn stone." ”

"If the city wall is built with this cement, it is not inferior to the current city wall, and the construction method is extremely simple, it does not require many people, and it will get twice the result with half the effort."

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

They are all veterans in the army, and this has begun to be discussed, the military use of cement.

"I'll see how sturdy this guy is."

Wei Chigong said, carrying a hammer and stepping forward, and everyone got out of the way. "Phew! Ah......h

As a result, like Cheng Chumo, he was shocked and retreated, and then in order to save face, his muscles burst out, and he had to smash this wall with a crazy output.

"Your Majesty, this cement is of great use to the imperial court, and it needs to produce cement in large quantities."

Li Jing also bowed and said, "I implore Your Majesty to change all the official roads in the world to this kind of cement road, and the speed of grain and grass supply will be increased several times." ”

"Aiqing, don't worry, I will seriously consider it."

As the lord of a country, Li Shimin is different from Li Jing, Li Jing is just a pure soldier, he has to take charge of the overall situation and consider the gains and losses in all aspects.

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 looking over, Fang Yiai was very familiar with current affairs, "The minister sent the method of firing cement to the palace." ”

He understands the importance of cement in engineering construction, and knows that he cannot be completely controlled by himself, so he has been mentally prepared for it, and there is nothing to worry about.

"Cement is of great use to the imperial court, and the widow of the house has a lot to do with you."

Seeing that Fang Yiai was so knowledgeable, Li Shimin was quite pleased, and then said: "The man of Xinfeng County has repeatedly dedicated himself to the country, and he has made great contributions to the country, so he is hereby named the son of Xinfeng County, and you are fully responsible for the cement firing after that." ”

"Thank you, Your Majesty."

Hearing that Li Shimin was burdening himself again, Fang Yiai agreed with a bitter face, he also understood Lao Li's temper, and he would not agree to resign, so there was no need to do more.

The emperor doesn't want to lose face?

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

"Congratulations on Fang Er."

Waiting for Li Shimin and the others to walk back, the eldest grandson Chong and Cheng Chumo came up to congratulate him, but Fang Yiai was sullen, and everyone was used to it.

"Look at your cowardice, you're not happy when you get promoted, others don't know, and they think you're drowning."

A few people played around and exchanged a few words, and he recovered.

……

Soon, the strange event of Fang Yiai's ice making in summer spread in Chang'an City, and the people were amazed by it.

Behind this, a wave of malice is pouring towards him.
