Chapter 1442

Li Shimin seriously doubted Niu Weili and dared to sell that piece of land without thinking.

If you really sell that piece of land, you'll have a lot of fun.

While Li Shimin was thinking, Zhang Feng put on his iconic white robe and came slowly with his hands on his back, but the roar of the mountain and tsunami was waiting for him.

Seeing this, Li Shimin waved his hand and said, "send a message to Li Xiaogong quickly and ask him to suspend the sale of land. Other things will be discussed when I return to the palace!"

As Li Shimin's voice fell, Zhang Feng also slowly stepped onto the platform.

At this time, on the high platform, Ouyang Xun and seven old scholar Sun Simiao, Li Gang and others sat in the front with the best line of sight, followed by Li Shimin, Wei Zheng and others. Although such a ranking would not appear on weekdays, why is Li Shimin's identity so at this time.

Zhang Feng first said hello to the people, looked at the little noble son, and a look of surprise flashed in his eyes. Finally, he didn't take it seriously. He waved his hand and pressed down all the students' voices. Then he said, "a few days ago, you all knew about some things, your classmates and Qian Wanli?"

"It is because of this phosphate fertilizer that Qian Wanli was poisoned by evil people. Therefore, the president today decided to take practical actions to uphold justice for Qian Wanli!"

"Someone is not spreading rumors. Is our phosphate fertilizer poisonous?"

"Isn't someone saying there's a problem with our phosphate fertilizer?"

"Today, without this mask, I'll do an experiment for you. You can learn these things in the future!"

"But one thing, you should remember clearly, that is, all learning is the foundation of the country. It is necessary to know how to feed back like that bird. Do you remember?"

Hearing the speech, more than three thousand students bowed down and said, "please obey the order of the Dean!"

When Zhang Feng heard the speech, he pressed his hands falsely, so that the people turned quietly and rushed to Yu Shinan and said, "your teachers, the boy started?"

Yu Shinan nodded and looked at Li Shimin. Seeing Li Shimin nodding without trace, he said, "let's start, but are you sure this thing is not toxic now?"

Sitting here are not only more than 3000 students from Chang'an University and white deer academy, but also craftsmen from the real Academy. The most important thing is that the emperor is here again.

If something goes wrong, it's no joke.

Zhang Feng said with an indifferent smile: "phosphorite basically won't cause people poisoning in the open and ventilated place. Moreover, such a small amount of measurement won't. as for the old cattle, they are poisoned because they have lived in the phosphorite mine all night and pulled dozens of carts of ore along the way. It's strange that they can't be poisoned."

"The last time Li Qian was poisoned, it was an accident. Because of improper experiments, the smell of phosphate fertilizer under high pressure leaked%..."

Wen Yan.

People suddenly.

Li Shimin pulled off his mask and said with a smile, "in that case, why do I wear this? Although it's exquisite, it's still a little suffocating."

While talking, Li Shimin was ready to light a cigarette.

But.

Before he could light a cigarette, Zhang Feng hurried to stop,.

Although the smoke won't cause any consequences, what if?

"Lao Li, at this time, we're still fine. This thing is not a joke. I don't know if this fire will cause any other problems. So, after the experiment, I'll invite you to smoke. How about it?"

"All right, don't say it, just watch it!"

While talking, Zhang Feng personally stepped down from the podium.

Seeing this, Li Chengqian and others hurriedly took out some of the prepared phosphate rock, put it on the roller and grind it slowly.

After Zhang Feng arrived in the field, the whole Academy was silent in an instant.

Everyone stared at Zhang Feng's every move.

With a small shovel, Zhang Feng made some powder on the grinding table, put it in a strange big belly bottle, and then lit an oil lamp under the bottle.

Then put a glass jar on the mouth of the bottle.

In a moment, a milky white smoke slowly flowed down the jar into another big bottle. The big bottle contained about half of the water, and the smoke magically went down the pipe into the bottom of the bottle. According to reason, the smoke can float.

But the magic thing is.

Instead of floating, the smoke sank to the bottom of the water!

Spinning under the water, some white powder slowly appeared at the bottom of the bottle.

Although the test bench is small.

But those who are not far away from the test-bed see it clearly. Only those students who are far away have long necks waiting for the test-bed.

Where have Li Shimin and others seen such a magical thing?

It can make the smoke precipitate in the water.

It's amazing enough.

One round of operation.

Zhang Feng pointed to the silent powder at the bottom of the water and said, "gentlemen, this is phosphorus, that is, what makes phosphate fertilizer!"
