Chapter 1167
After the three-day basic training is over.
When the sun just rose on the fourth day, Zhang Feng was dragged out of the sedan chair dazed by the subordinates, and was thrown at the gate of Cháng’ān University. The long distance away.
Zhang Feng squatted at the door for a long time before he was relieved, rubbing his fascinated cheeks, and then walked into Cháng’ān University.
The security of Cháng’ān University today is particularly strict.
In addition to Jia Daoren at the door personally pacing the Double Edged Saber at the door, he also directly mobilized more than 30 five-big and three-thin men from the White Deer Academy of Classical Learning.
These guys all carry a weird diamond-shaped thing like a bamboo sliver in their hands.
Anyone who knows will definitely know his terrifying name.
Mitsubishi Army thorn.
Those who didn’t know thought it was just playing.
In the courtyard where Zhang Feng needs to do experiments today, there is no one else except Zhang Feng, and Li Chengqian and the others.
In the middle of the yard, Li Chengqian and the others built an open-air laboratory perfectly for Zhang Feng according to the scale of the laboratory directly in the room.
The table is covered with a white flowery orchestrated list, which is full of things needed for this experiment.
The few remaining Ethyl Alcohol have been divided into countless Ethyl Alcohol lamps, which are now burning.
There are even a few that are not enough, so we can only use tung oil lamps instead.
On the experimental table, there is not only phosphate rock, but also some nitrate, charcoal, etc., which Zhang Feng collected by himself, which only appear in the kind of water where no one moves for a long time. Some rust, red, green and green set a large table.
Seeing Zhang Feng’s arrival, several people stood straight in a hurry.
“Hello Dean!”
Zhang Feng waved his hand to let all the people sit down, and then said, “I won’t talk about the rules. Today’s experiment is very Important, important enough to change the history of Great Tang and change the existing farming methods, are you all ready?”
“Ready!”
Can they Are you ready?
When is this all?
And since Zhang Feng said that the period of prosperity is beautiful, their Laozi pointed their noses directly when they learned about it. If they can’t learn it, they will be expelled from the house!
Who the hell can stand this?
Others are okay, what about Li Chengqian?
He is Crown Prince!
Although expelled from the house is impossible, his reputation and impression in Father Emperor’s heart will obviously be minimized!
This is the most unbearable for him.
This is tantamount to obliterating one’s own way of Crown Prince!
After waiting for a few people to take care of the protection, Zhang Feng picked up the experimental equipment on the test bench and said: “Although the extraction of phosphorus is simple, there are some troubles. The most important thing we do is Analyze the composition of phosphorus.”
“Do you understand the composition of phosphorus?”
This is something they have been memorizing by rote these days. If you can’t remember, Zhang Feng will really go crazy.
After seeing a few people are nodded, Zhang Feng pointed to a pot-bellied glass container as big as a washbasin and said: “In fact, the experiment of extracting phosphate fertilizer is very simple. It is to grind the components of the phosphate rock and separate it. Come out, and then distill it into phosphorus element vapor through this container, and then guide the vapor through this conduit to this glass container, let him encounter water, and naturally dissolve and precipitate…”
Zhang Feng experimented with phosphorus步骤都讲述了一遍，然后让Li Chengqian 上来，带上特质的Rubber 手套，然后把磷矿研磨成分，这个步揍很简单。
On the other hand, Zhang Feng filled the container with water, placed it on the tung oil lamp, adjusted the flame of the oil lamp to the highest level, and poured the phosphor into the water.
At this moment, something incredible happened to Li Chengqian and the others.
As the oil lamp burned, the glass container actually began to boil violently, and then the mist in the glass container gradually sank.
After that, no one can see the scene, but you can see that in a curved glass tube at the top of the container, a trace of mist is slowly moved towards the tube. The other end flows away.
The other end of the pipe is placed at the bottom of another container.
Slowly.
More and more mist entered another container, and the mist gradually became heavy.
Zhang Feng also pointed to the container to explain the steam dynamics to everyone.
But at this moment, Zhang Feng didn’t pay attention. What everyone didn’t notice was that the water in the container burned by the oil lamp slowly dried up, but because of the fog, everyone Did not notice.
Only a loud bang was heard.
In an instant, all the glass containers on the entire test bench burst open, and even the glass shards exploded far away, on the back of Zhang Feng and the faces of Li Chengqian and the others. , It was sprayed with a large amount of vapor atomized dust containing phosphorus in an instant.
“Um–!”
Everyone was stunned.
Although the temperature of the draft tube was reduced, and the steam was not hot, no one was injured, but Zhang Feng was the first reaction to come.
I drank it in a hurry: “Everyone immediately cover their mouths and noses and give Dang immediately! Drink a jar of vinegar!”
? ? ?
Everyone is confused.
What is this operation?
Isn’t this just a firecracker?
Do you still drink vinegar?
But everyone still followed Zhang Feng’s instructions and rushed to Cháng’ān University weakly.
Find vinegar to drink…
