He Tiancai found that these chemicals are all finished products, but how can the finished products have a strange taste, there is only one reason, that is, Lu Hongjie relied on his chemistry teacher's experience to move on these finished products, and he has been out for so long, there is an obvious alibi, and everyone will think that it is caused by himself.

These test samples are put together, and they have begun to boil slightly, He Tiancai knows that this is the prelude to the explosion, but he didn't expect Lu Hongjie to be so vicious, as long as the laboratory explodes, the laboratory is only one of himself, then he will have to resist all the responsibilities.

After thinking about the key clearly, He Tiancai touched his smooth chin, looked at the chemical agents in front of him, and the super black hole brain began to display the ingredients and effects of these chemical agents in He Tiancai's mind.

"There is still help!" He Tiancai calculated the time, these chemicals will explode violently in about five minutes, and if it is light, it will blow up everything around the laboratory, and if it is serious, I am afraid that I will not be able to protect myself.

"I didn't expect you to be so vicious!" He Tiancai licked his lips and said with a smile: "Then I will return my own body in the way of others." ”

He Tiancai quickly analyzed the materials and properties of these chemical agents, and he wanted to extend the explosion time by fifteen minutes.

He Tianyan thought that after five minutes, Lu Hongjie would definitely wait and see if there was no explosion in the laboratory, and then go inside to see what was going on, so it should be just right for him to delay the explosion time to fifteen minutes.

He Tiancai only had five minutes to go, and he quickly picked up the container configuration, and his technique was extremely fast, just like a veteran who often did chemical experiments, mainly due to his brain completely listing all the steps.

There were still four minutes left after everything was arranged, and He Tiancai waited inside for five minutes.

And these five minutes are quite difficult for Lu Hongjie, he hid in a corner and kept waiting for the chemical laboratory to make a shocking explosion, every minute and every second has a feeling of living like a year, and he even has a kind of pleasure: "He Tiancai, let you and me rob women, this time Lao Tzu will make you suffer a dumb loss!"

Lu Hongjie looked at his watch from time to time, and as the time passed, his brows slowly tightened: "Why hasn't it exploded yet? This is not scientific, six minutes have passed!"

At this time, Lu Hongjie saw He Tiancai swaggering out of the chemistry laboratory and walking towards the classroom.

"What's going on?" Lu Hongjie frowned, he had demonstrated this plan many times in his mind, and this chemical principle was also known to very few people, simple but remote knowledge, it was impossible for him to misconfigure!

"I have to go and see!" Lu Hongjie walked quickly towards the chemistry laboratory.

And He Tiancai stopped when he turned the corner, and watched Lu Hongjie walk into the chemistry laboratory, with a smile on his face that had succeeded in his conspiracy, and he muttered: "The time seems to be bad, there are still three minutes!"

As soon as Lu Hongjie walked into the laboratory, he smelled a pungent smell, which was the smell of the chemicals he had configured, he frowned, and said, "Why is it only reacting now?"

However, at this time, He Tiancai had already left, and it was useless to ask for this chemical.

Lu Hongjie sighed and said, "It seems that I can only find a chance to clean up this stinky boy in the future." ”

It was imperative that their chemistry be terminated and that they could not be allowed to explode again.

Lu Hongjie took out a few chemical agents, poured them into a glass bottle, and neutralized them with the chemical experiments processed by He Tiancai.

Unexpectedly, at this moment, the chemical agent suddenly boiled, thick smoke rolled out, and the entire laboratory exploded with a "bang".

Fortunately, Lu Hongjie found that something was wrong at that time, as a chemistry teacher, he had a very strong ability to sense danger, and when he found out that something was wrong just now, he immediately rushed outside, although he rushed quickly, but the aftermath of the explosion still shook him away, and a strong pain hit him behind him.

Watching Lu Hongjie enter the laboratory from a distance, and watching the laboratory explode, He Tiancai showed a smile, and after raising his middle finger towards the laboratory, he walked towards the classroom with peace of mind.

The explosion in the chemistry lab was definitely something that shocked the whole school, and it was so loud that anyone who was not far from the chemistry lab was taken aback.

"Oh no, the chemistry lab has exploded!" a female teacher shouted outside in a panic.

Then some students shouted along, holding fire extinguishers in their hands and spraying the flames indiscriminately, which stabilized, but at this time the chemistry laboratory was already a mess.

"How so....... How could this be!" Lu Hongjie sat on the ground in a daze, regardless of the fact that his back had been injured, he didn't think at all why the chemical experiment he had prepared couldn't explode within the specified time, and if it couldn't explode within the specified time, it would suddenly explode when he neutralized the experiment.

And all this is of course He Tiancai's masterpiece, he knows that if Lu Hongjie finds something wrong after he comes in, and sees himself leaving, he will definitely terminate the chemical reaction.

He Tiancai already knew which chemicals Lu Hongjie would use to terminate the reaction of the chemical experiments in the glass bottle, so he would calculate and add some other chemicals, if Lu Hongjie used these chemicals to terminate the chemical reaction in the glass bottle, it would only be counterproductive.

Lu Hongjie sat on the ground and was silent for a long time, and the principal also rushed over in person, and when he saw that the chemistry laboratory was in a mess, the corners of his eyes couldn't help twitching.

"Lu Hongjie, what the hell is going on!" the principal asked sharply. Fortunately, there were no casualties, otherwise he would probably not be able to escape the blame!

"What's going on?" Lu Hongjie shook his head, his eyes were blank, and said, "I don't know...... I don't know!"

"The surveillance footage in the lab is broken!" said a teacher who went to investigate the surveillance footage.

In fact, the surveillance video was also deliberately destroyed by Lu Hongjie, so that he could carry out his plan with peace of mind.

"Who's in the lab at the end? Who is in the lab?"

"There are only two people in the laboratory: He Tiancai and Teacher Lu Hongjie. A classmate took the initiative to say: "Just now, Mr. Lu Hongjie asked He Tiancai to go and fight." ”

Everyone's eyes fell on Lu Hongjie.

Lu Hongjie suddenly had a stirring spirit and shouted: "It's He Tiancai, it must be He Tiancai's ghost!"
