Teacher Liu pursed his lips, and his face also looked down on Ye Bai a little, learning can be bad, but you must be honest.

If you miss an English subject, you can still score 600 points?

Isn't that bragging?

If there really were such people in the school, why didn't they come to their chemistry department?

As soon as Teacher Liu said this, all the students nodded, something that the teacher had never heard of, nine times out of ten this kid was bragging.

Shen Chengguo sneered, as if he had exposed Ye Bai's true face, raised his head and chest, the superiority of the scholar seemed to be written on his face, found an empty seat and sat down, ready to go to class.

After sitting down, Mr. Liu and Shen Chengguo glanced at each other, and instantly understood each other's thoughts.

Mr. Liu said lightly, "Our chemistry department is the best major in the school, and the laboratory course is also the most popular course, so students from other majors are welcome to audit." Since there are new students here to watch, let's start the experiment today. ”

"Shen Chengguo, come up and demonstrate. ”

Shen Chengguo showed a faint smile on his face, got up and walked onto the test bench, a dazzling array of various medicines and equipment, if a layman would have been stunned.

However, he Shen Chengguo is the top student in the college entrance examination and a genius in chemistry, so he naturally knows the experiment well.

took out all kinds of test tubes, all kinds of medicines, and had an almost full score operation on the laboratory table, which dazzled the students.

Suddenly, Shen Chengguo picked up a small beaker, which contained a pale yellow liquid.

Walking in front of Ye Bai step by step, Shen Chengguo put the beaker in front of him with a playful smile on his face, and said lightly.

"The 'master' of Feng Shui, do you know what this is?"

"Hehe, looking at your expression, I shouldn't know, this, it's called nitroglycerin!"

After finishing speaking, Shen Chengguo took out a lot of medicines and showed them one by one in front of Ye Bai and all his classmates.

"Ethanol, plus sodium nitrate, sulfuric acid, nitroglycerin, ammonium nitrate, plus a little graphite ......"

Shen Chengguo held the big beaker in his hand in front of Ye Bai and said with a playful face.

"Do you know the equation? It's a graphite bomb, and if I shake it slightly, it will—"

"Bang!"

Shin Sung-kook also deliberately made a noise, as if he wanted to scare someone.

"It's going to bang and blow you away, how about it, do you want to experience it?"

Shen Chengguo's remarks just now seemed to be very humorous in the eyes of the chemistry students, causing the whole class to laugh.

In their eyes, it is the most interesting thing to scare the layman with this homemade graphite bomb.

Of course, it is naturally impossible for Shen Chengguo to shake this thing violently, isn't that self-defeating?

He showed this method just to let Ye Bai know that the chemistry department was awesome and that he was very knowledgeable!

Teacher Liu was smiling all over his face, and seemed to be very satisfied with Shen Chengguo's method.

"See, this is the power of chemistry, presumably the master of the feng shui system has been shocked, right?"

One old and one young, singing and harmonizing, looked at Ye Bai with a playful look, as if waiting to see his jokes.

However, to their disappointment, Ye Bai's face did not change at all, looking at the stunned looks of Shen Chengguo and Teacher Liu, Ye Bai shook his head speechlessly.

"This little bit of pediatric stuff has become a bragging capital in your eyes?"

What the?!

didn't wait for Shen Chengguo to speak, and Mr. Liu was the first to be unhappy.

"Boy, it's best to consider your identity before you speak, saying that we are pediatrics? Do you know, that thing in Shen Chengguo's hand just now can kill you at any time!"

Shen Chengguo sneered, pointed to the test bench and said, "You think we are really pediatrics, so you come up and point out?" If not, get out of here as soon as possible!"

Mo Xiaojin stood up and pointed at Shen Chengguo, "Go up, go up! What are you arrogant about! Stinky Ye Bai, go up!"

Ye Bai rolled his eyes, this Mo Xiaojin always likes to be in the limelight, but he doesn't have the ability to do it yet.

In desperation, Ye Bai had no choice but to walk to the test bench under the gaze of everyone.

At the bottom of the test bench, I took out a piece of granite of dozens of catties, this granite was originally used for experiments on weekdays, and at most a small piece was used each time.

Grinding, calcination, refining.

Ye Bai used the most standard, professional, skilled and rapid method to refine a large piece of granite into a metal particle that is almost invisible to the naked eye.

Black-gray, extremely fine, was carefully placed in tweezers by Ye Bai.

Seeing this scene, Teacher Liu frowned, and his face was a little solemn.

Ye Bai's quenching method just now was very professional, and he didn't dare to say that he didn't understand chemistry at this time, but what did he refine with such a large piece of granite?

There was an extremely terrible thought that flickered in Mr. Liu's mind, but he didn't dare to be sure.

When Ye Bai took out several extremely dangerous chemicals and mixed them together, Teacher Liu's face finally changed!

"Uranium! It's metallic uranium! You're crazy!"

Uranium!

Hundreds of students from the entire chemistry department stood up in shock!

What is uranium metal, those who study chemistry should know that that rare metal contains extremely powerful power, and it is also one of the most important metals for the configuration of atomic bombs!

This Ye Bai, is he going to configure an atomic bomb in the classroom!

It's pure madness!

Although I don't know why this guy has such knowledge, the small piece of metal pinched in Ye Bai's tweezers is definitely uranium.

Even if it is 108,000 miles away from the real atomic bomb, as long as the metal uranium comes into contact with those liquids, it is enough to blow up the entire school building!

Ye Bai smiled with a harmless smile, holding a beaker in his left hand and tweezers in his right hand, walked up to Shen Chengguo step by step, and said lightly.

"Would you like to try this?"

As a top student in the chemistry department, Shen Chengguo certainly knows what this thing is.

"Get out of here! Get out of here!"

Shen Chengguo was frightened and his soul did not possess his body, he sat on the ground and staggered back, at this time Ye Bai was like a devil in his eyes, how could this guy know how to refine uranium metal?

Teacher Liu pointed at Ye Bai, his face full of horror!

"Stop! Stop! I order you to stop as the head of the chemistry department!"

Ye Bai walked towards Teacher Liu again, and under the terrifying gaze of all the students, the tweezers were gently loosened.

Boom!

The metal fell into the liquid.

"Ahhh

There was a screaming sound from the whole classroom, and even Teacher Liu sat on the ground in fright, screaming heartbreakingly.

However, the imaginary explosion did not come, and a few seconds later, Teacher Liu reacted, raised his head and looked at the thing in Ye Bai's hand in disbelief.

"What's going on, this can't be!"

Ye Bai walked up to Teacher Liu and put the medicine and tweezers in his hand.

"The purpose of learning knowledge is to serve the motherland, not to show off. ”

"This small piece, not uranium metal, but uranium dioxide, naturally does not explode. ”

"You know, the process of making an atomic bomb is a vacuum, and when the metallic uranium is oxidized to uranium dioxide, it is ineffective. ”

As he spoke, Ye Bai patted Teacher Liu's shoulder and said earnestly.

"It's common sense that metals are oxidized in the air, and you're a professor, don't you even know this? ”

After finishing speaking, Ye Bai turned around and left the classroom.

Only the word hehe was left, echoing in the classroom.
