Chapter 270 Chu Bei: Do you feel like you lost?
While Bai Shengli was still staring at a pile of instruments and frantically looking for the equipment needed for the experiment, Zheng Yun had already started his first experiment.
The slender fingers of his left hand held a small measuring cup, his white fingertips exerted a little force, and his pair of brown eyes stared intently at the flame of the alcohol lamp on the table.
There was a piece of metal being roasted over the alcohol flame. Zheng Yun didn't even look at the watch on his wrist, but silently counted the roasting time.
The total time is 15 seconds. One second more or less will seriously affect the accuracy of the experimental results.
He was very serious about everything he did. Even when he went to the countryside to farm, he was always an advanced individual among the educated youth team every year.
When doing the experiment, he put aside the grudges between him and Bai Shengli and devoted himself to the experiment.
On weekdays, because he runs a business and has to support his family, he often appears to be a bit worldly-wise and smooth.
He was a completely different person in the laboratory. He was full of confidence, and his slightly raised eyebrows revealed a bit of arrogance.
He was thin, fair and clean, and only at this moment did he show the appearance of a student.
That rare feeling of youthfulness adds a touch of scenery to the boring laboratory.
This is the true Zheng Yun who doesn’t like to talk.
He liked to listen to the sound of chemicals colliding. The ping-pong sound soothed his restless heart and was extremely pleasant to the ear.
While observing the changes in the new experimental objects, I also observed the steps that had been completed and wrote down the experimental data carefully.
Time passed quickly second by second, and soon, Zheng Yun had completed the first experiment.
After all the experimental data were calculated and recorded, he finished his work perfectly and went out to work on other experimental houses.
However, Zheng Yun did not do as Chu Bei asked, but turned his attention to another pile of experimental supplies.
He had no desire to stand out or win a grand slam, but when he saw the experimental equipment, he really liked it.
I just really want to give it a try.
Do it in various positions.
Do it until you feel good.
Chu Bei, who was standing at the door, was almost going crazy with anxiety. He saw that students from other schools were constantly changing laboratories and cooperating with each other to complete experiments.
There was no change on Yan's side except that the laboratory in the car was changed from a Class B laboratory to a Class C laboratory.
"It's over. I don't think I can stay as the principal for long."
At this time, Bai Shengli barely completed an A-level experiment, and he had one more experiment left to do:
Experiment on reduction of copper oxide by charcoal.
The experiment is very simple. It is to use charcoal powder to reduce copper oxide powder, and then pass the generated gas into clear lime water, and the black copper oxide will turn into shiny metal.
This is a high school chemistry experiment. It is very simple to do, but Bai Shengli is completely unable to concentrate on doing it.
There were ten experiments in total, and he had already spent two hours in three hours to complete one experiment.
Seeing that there was little time left, Bai Shengli sank to the bottom.
Originally, he had only learned three experiments by cramming, but now in the A-level questions that Yan drew, there were two that he knew.
He knew very well that if the game ended and Yan lost because he had not completed these experiments with the lowest difficulty, then Chu Bei would find a reason to re-examine his college entrance examination results.
By then, the school that his father went to jail for and his uncle jumped off a building to get him to would be the last thing on his life.
With less than forty minutes left, Zheng Yun finally walked out of the experiment reluctantly.
Chu Bei looked at Zheng Yun from a distance, thinking in his heart, no matter what, Zheng Yun at least completed a D-level experiment.
He could comfort himself in the thought that he had not lost too badly.
At this moment, there are still two C-level experiments that have not been completed, and eight A-level experiments that have not been completed. Chu Bei feels that Yan has no hope.
