Li Shimin seriously doubted whether this Niu Weili would dare to sell that piece of land without using his brain.
If he really did sell that piece of land, then there would be a lot of trouble.
Just as Li Shimin was letting his imagination run wild, Zhang Feng changed into his iconic white robe and slowly walked over with his hands clasped behind his back. What awaited him was the sound of a tsunami.
Seeing this, Li Shimin waved his hand and said, "Quickly send a message to Li Xiaogong and tell him to stop selling the land. As for other matters, wait until I return to the palace to discuss them!"
As Li Shimin's voice fell, Zhang Feng also slowly walked up to the high platform.
At this moment, on the high platform, Ouyang Xun, Old Elementary Scholar Sun Simiao, Li Gang, and the others sat at the front with the best view. Behind them were Li Shimin, Wei Zheng, and the others. Although this kind of arrangement usually didn't happen, it was because of Li Shimin's identity that this was the case.
Zhang Feng first greeted everyone and glanced at Little Guizi. A trace of surprise flashed through his eyes, but in the end, he didn't take it seriously. After waving his hand to silence the students, he said, "A few days ago, because of some matters, you all know about your classmate Qian Wanli's matter, right?"
"It was because of this phosphate fertilizer that Qian Wanli fell into the hands of evil people. Because of this, I have decided today to use practical actions to uphold justice for Qian Wanli!"
"Didn't some people spread rumors that our phosphate fertilizer was poisonous?"
"Didn't some people say that there was a problem with our phosphate fertilizer?"
"Then today, I won't wear this mask and will do an experiment for everyone. You will be able to learn these things in the future!"
"But there is one point that you must remember clearly, and that is that everything you learn is the foundation of the country. You must be like those birds and know how to reciprocate. Do you all remember?"
When the three thousand plus students heard this, they all bowed and said, "We obey the dean's orders!"
Hearing this, Zhang Feng gestured with his hands to silence the crowd. He turned to Yu Shinan and the others and said, "Respected teachers, is that kid going to start now?"
Yu Shinan nodded and glanced at Li Shimin. Seeing Li Shimin nod without a trace, he said, "Then let's start. But are you sure that this thing is no longer poisonous?"
Apart from the more than three thousand students from Chang 'an University and White Deer Academy, there were also craftsmen from the various academies present. Most importantly, the Emperor was also present.
If something went wrong, it would be no laughing matter.
Zhang Feng smiled indifferently and said, "The phosphate stone will not poison people in an open and ventilated place. Moreover, with such a small amount, it won't poison people. As for Old Niu and the others, it was because they stayed on the phosphate mine mountain for a night and pulled dozens of wagons of ore along the way. It would be strange if they were not poisoned."
"And the poisoning of Li Gan and the others was an accident. Because of the improper experiment, the high-pressure phosphate fertilizer leaked out …"
Hearing this.
Everyone was enlightened.
Li Shimin pulled off the mask on his mouth and said with a smile, "If that's the case, why should I wear this? Although it's exquisite, it's still a little suffocating. "
As he spoke, Li Shimin was about to light a cigarette.
But.
Before he could light the cigarette, Zhang Feng hurriedly stopped him.
Although the cigarette would not cause any harm, but what if it did?
"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 is over, I'll treat you to a cigarette. How about that?"
"Okay, let's not talk about it. Just watch!"
As he spoke, Zhang Feng personally walked down from the podium.
When Li Chengqian and the others saw this, they hurriedly took out some phosphate ores that they had prepared in advance and put them on the grinder to grind them slowly.
When Zhang Feng arrived on the stage, the entire Academy was silent.
Everyone stared at Zhang Feng's every move with their eyes wide open.
They saw Zhang Feng use a small shovel to grind some powder on the grinder and put it in a strange bottle with a big belly. Then, he lit an oil lamp under the bottle.
Then, he put a glass jar over the mouth of the bottle.
Not long after, a milky white smoke flowed along the canister and slowly flowed into another large bottle. The large bottle was about half filled with water, and the smoke miraculously flowed along the canister into the bottom of the bottle. Logically speaking, the smoke should be able to float.
But the amazing thing was.
The smoke not only did not float, but also sank to the bottom of the water!
It swirled at the bottom of the water, and some white powder slowly appeared at the bottom of the bottle.
Although the test bench was not big.
But the people who were not far from the test bench saw it clearly. Only the students who were far away stretched their necks and waited for the test bench.
And Li Shimin and the others had never seen such a magical thing.
It could actually make the smoke settle in the water.
This was amazing enough.
After a round of operation.
Zhang Feng pointed to the powder at the bottom of the water and said, "Everyone, this is the phosphorus element, which is the material used to make phosphorus fertilizer!"
"…"
