When Li Chengqian returned to Zhang Feng's house, the building was already empty. When he asked, he knew that Chumo and his family were in the same situation as him. They went later and were immediately kicked out of the house by their father.

The meaning is clear.

These boys must have gone home with smuggled goods like him.

When Li Chengqian came to Chang'an University, Zhang Feng just scolded Chumo and others.

Originally, a set of experimental instruments, large and small, were complete. Now it's good. Now it's half less!

Anyway, the experiment at this time has not been affected yet. Otherwise, it will really be dead. After all, tomorrow is the time for autumn seed sacrifice.

Seeing Li Chengqian's arrival, Zhang Feng pointed to Li Chengqian's nose and asked, "I ask you, can you steal my test equipment from home like them?"

How can Li Chengqian admit this?

Chumo was scolded. He had heard it when he was at the door, but how could he avoid Zhang Feng's eyes.

Angry Zhang Feng pointed to several humanitarians: "what is this? It's public property. You know the harm of the experiment. If you take it back, it will harm your family. What do you want? Tell me, why steal it?"

Several people's eyebrows jumped.

Together, the other day you asked us to steal the cicada yarn at home. Have you forgotten?

If we don't bring something back, can we stand here intact now?

But they dare not say!

Zhang Feng is angry now. If they say this, it's strange that they won't die, and they have a major mission. If they can't get the glass back, they'll be finished.

Zhang Feng felt bored after venting his dissatisfaction for a while.

There's something wrong with these goods today.

When can they stop yelling back?

But this is no longer the time to say this. After all, Zhang Feng knows that tomorrow will be the sacrificial ceremony. After the sacrificial ceremony, it will be the real autumn planting. The most important thing is that once this thing misses the autumn planting, it will have some trouble. Although spring planting can be used, Zhang Feng has other plans.

That's pesticides.

It would be great if we could get rid of locust eggs in the fields by using insecticides in spring, but if we missed it, it would really be GG.

And most importantly.

At this time, Dr. Sun Simiao and Dr. Sun are already preparing insecticides on the mountain, but they don't wait.

In case, the longer the time is delayed, the three-year locust plague in Zhenguan in history will break out. At that time, it will really float corpses thousands of miles.

As soon as he thought about it, Zhang Feng couldn't help feeling a faint sense of crisis.

This sense of crisis does not mean that he can be alone with pesticides.

"Stop pestling and start the test quickly! I won't participate in it this time. I have prepared an hourglass for you. As long as the sand in the hourglass runs out, turn off the oil lamp under the test tube immediately!"

While Zhang Feng was talking, he pointed to a thin glass tube in the middle of the test bench behind him, which was like suddenly tightening a jar with a rope.

In the glass, at this time, Zhang Feng has put the sand side at the bottom of him upward.

With the movement of Zhang sand, in the stunned eyes of the people, the sand is flowing in another container down a little bit.

When several people saw this, they were about to come forward, but they were afraid of the poisoning before. At this time, they looked at me and you. They couldn't help prevaricating with each other.

Zhang Feng patted his forehead and said, "you're all dizzy. Come on, put this thing on my mouth!"

Zhang Feng took out a large handful of pure cotton cloth from his mind and handed it to the people with two rings.

Most of all, he threw these things into a jar of Baijiu and soaked them, and then handed them to a few people. Some of them were suspicious, but still kept this on their lips according to Zhang Feng's practice.

In an instant, the smell of wine made several people suck their noses.

"Feng Zi, what is this? Didn't you say you can't smoke and drink? And if you take this with you, you won't be poisoned?"

Li Chengqian asked hurriedly.

Zhang Feng nodded and said, "this thing is called a mask. Once it is stained with alcohol, it will isolate most of the harmful substances in the air, alcohol, and when I operated on Xiaohu before, do you remember?"

Several people nodded suspiciously.

Zhang Feng continued: "alcohol is anti-virus, but now we don't have it, we can only replace it with wine. Once this thing is worn, basically the phosphorus poison won't be in it, but if you dare to steal the wine on the mask, it's another matter."

"This thing absorbs all the toxins brought in when you breathe. Once you dare not drink it, the immortal can't save you!"

Zhang Feng severely threatened several people.

I can't help but make several people who are secretly squeezing wine with their lips look sluggish.

I didn't dare to steal it.

When Zhang Feng saw this, he waved his hand and said, "let's start! While encouraging me to succeed today, you must hand in ten kilograms of phosphate powder to me, otherwise it will be regarded as a failure! Don't say what you want and what you haven't said in the future, and you won't get it if you say it!"
