Chapter 1443

Zhang Feng's words.

In an instant, all the students were in an uproar.

Even with Yu Shinan on the stage, he hurried to Zhang Feng with Sun Simiao wearing a mask. Li Shimin wanted to come, but he was pressed on the stool by Niu JINDA. He couldn't remember, and the sky was red.

Li Shimin was so anxious that he stared at Niu JINDA and said, "what do you mean?"

"Second master, you'd better bear it first. I know the power of this thing. I can't smell it. Feng Zi is young. He can resist..."

"So you mean, I'm in poor health?"

In an instant, Li Shimin's words shocked the ox into the tiger's body.

Hurriedly explained: "no, no, no, I mean... Yes..."

After hesitating for a long time, Li Shimin became impatient and said, "I came here today just for this thing. If even I shrink back, wouldn't it be a smile to spread it?"

Wei Zheng and others were also frightened by what Niu JINDA and the emperor had done. However, Wei Zheng hurried forward to persuade Li Shimin because of this.

"Second master, just look at it. Don't come forward!"

"Yes, yes, second master, if you come forward, what a sin would we have?"

Li Shimin understood.

These people have already discussed it.

Just afraid of what he's going to do.

I'm afraid something will happen to him, but if he doesn't go today, he's really sorry for his conscience if he doesn't witness it with his own eyes!

"Shut up!"

Li Shimin's slightly warm and angry low voice made several people close their mouths in an instant.

Although Yu Shinan and others heard it, it's hard to say. After all, it's a matter in the court. What can they say?

And they all saw it for the first time, and it was strange and tight.

After all, some things are really helpless.

Under Li Shimin's scolding, although Fang Xuanling and others were still reluctant, after all, this was a mountain, and they didn't dare to say anything, so they had to give way to Li Shimin.

Li Shimin thought about it and put on his mask.

In fact, he really doesn't want to wear this thing. He always doubts whether this thing is unlucky.

But if you don't wear it, it will make people wordy, so Li Shimin chose to wear it.

When several people came to the stage, the first round of refining was already over. Zhang Feng was sorting out the residue in the appliance and a handful of phosphate fertilizer.

In fact, the extraction of phosphorus fertilizer is very simple. It is to add some sodium nitrate, that is, lime powder, into the water, and then introduce the phosphorus gas distilled at high temperature into the water. After chemical reaction, the precipitated phosphorus fertilizer is phosphorus fertilizer, also known as phosphorus nitrate.

This is also the simplest thing Zhang Feng can make according to the things of the current era.

It is also the most acceptable thing for everyone.

Zhang Feng is actually very difficult.

In fact, there is no need to do these things, but on the one hand, he can't see it anymore. He really doesn't know about the locust disaster next year. After all, only through planting and irrigation this year, wrapping the medicinal powder in the water, can we achieve a series of obstacles, and some things next year, can we kill locusts.

But

Zhang Feng doesn't have the ability to kill locusts as a whole. At least, he has to wait until the hot-air balloon can be accepted by everyone, and then use the hot-air balloon to spray pesticides on a large scale, so as to stop the locusts.

It's just within the Tang Dynasty. As for overseas affairs, Zhang Feng can't take care of so much, but even so, whether he can stop locusts at that time is two different things. Therefore, on the premise of ensuring that the people of his college and Lao Li and others are not hungry next year, Lao Niu found it inadvertently, This made Zhang Feng think of this method.

Otherwise, Zhang Feng really doesn't want to do this painstaking thing.

And he was stabbed out by people. It doesn't matter whether it will be spread after the harvest next spring.

But did you fucking let the old man surnamed Kong come to the mountain and quietly spread the phosphate fertilizer?

That's what happens next.

Therefore, Zhang Feng is indeed in a bad mood today.

This feeling of being put aside by others makes him feel very depressed. Therefore, since you are guessing, I will directly show you a showdown. I am not afraid if you can hide your tricks,

This is Zhang Feng's confidence.

Believe me, can support a belly round, don't believe me, ha ha.

Go for your own good.

Li Shimin and others fooled around the experimental platform, while Li Chengqian acted as a guide and loudly introduced the concept of the experiment.

And some things on the experimental platform, professional terms.

Such as sodium nitrate and so on.

Not to mention that Yu Shinan and others have been thinking about Zhang Feng's physics teaching book all day, even the more than 3000 students are not calm at this time.

Is this really what we learn on weekdays?

See Zhang Feng do not speak.

A student hurried forward and asked loudly, "dare you ask the Dean, this thing called experiment is really so magical. Such a track, that thing like snow, is the phosphate fertilizer that can increase the output of grain?"
