Reborn in 1976, teach him how to be an official

With only a few large computers in the country, research institutes had to submit applications in advance if they wanted to use even one hour of computing power. And even if they did, they still had to wait in line.

At that time, Liu Hongyi and his colleagues visited a large computer and their eyes became bloodshot with envy.

Most of the design data for my country's first hydrogen bomb was calculated using an abacus.

Although Liu Hongyi's proficiency in using the abacus is not as good as Tan Dexi's, after this period of restorative practice, he will definitely have no problem using it to assist in calculations.

It saves time, effort, and draft paper.

Liu Hongyi immediately took Tan Dexi's old abacus and set it up in the laboratory.

Jin Yunfeng and others gathered around, ostensibly to watch the fun, but in fact to "supervise" and would never allow Tan Dexi to give Liu Hongyi any instructions.

Good boy, I want to see what you have the ability to solve the problem that all the researchers from our three institutes spent several months to figure out in just one night!

Liu Hongyi began to solve the problem confidently.

Watching him skillfully using the abacus and writing out a dizzying long list of formulas and mathematical symbols on the draft paper, Jin Yunfeng had a vague feeling that "something was not going well."

Look at this posture, this guy really knows...

Gaudi and the other person also began to feel uneasy.

Only Zhang Chenghai came over and watched Liu Hongyi solve the problem very attentively, and would interrupt from time to time to ask a question. Liu Hongyi explained it to him casually, but his hands did not stop at all, and the beads clattered without a trace of disorder.

This skill is quite amazing!

As time went by, Jin Yunfeng and others began to yawn and hurriedly covered their mouths with their hands.

Only Tan Dexi's eyes became brighter and brighter, with infinite surprise in his eyes.

Even he didn't expect that Liu Hongyi was such a genius.

With this speed, I'm afraid even if he goes into battle himself, he won't be able to achieve this speed.

No, maybe even his speed is not as fast as Liu Hongyi's.

After all, Liu Hongyi's current biological age is sixteen, so how fast can his brain work? This advantage of youth is too great.

Liu Hongyi naturally knew that Old Tan was shocked, and couldn't help feeling secretly ashamed.

Teacher, please call the police! Someone is "cheating" here, and the situation is getting out of control...

As it turned out, Liu Hongyi was too modest.

He just said that it might be possible to try to solve an equation in one night, and then, the "hack" solved the first big equation in just over two hours, a little after twelve o'clock.

Just now, Tan Dexi did nothing but watched Liu Hongyi solve the problem intently.

Only a purely academic expert like him can be so focused.

The same goes for Zhang Chenghai.

Jin Yunfeng, Gao Di and the other two were already yawning and regretting their actions deeply.

This is pure self-inflicted trouble.

Are you going to sleep tonight?

Of course, the most important thing is that they can't understand it, so it's boring.

Zhang Chenghai studied hard and didn't feel sleepy at all.

"It's done... Come on, Gaudi, take out the answer and compare it to see if his solution is correct..."

Jin Yunfeng forced himself to cheer up and urged Gaudi.

"no need!"

Tan Dexi snorted coldly.

“That’s absolutely right.”

Jin Yunfeng smiled awkwardly, but still urged Gaudi to bring out the "standard answer".

He simply didn't trust Old Tan and was afraid that the old man would favor his "apprentice".

Gaudi hurriedly took out the correct answer from his schoolbag, glanced at it, his face changed slightly, and he whispered to Jin Yunfeng: "Yunfeng, the answer is correct..."

"show me!"

Tan Dexi snatched the answer, then picked up Liu Hongyi's answer sheet and compared them carefully.

Then he discovered that Liu Hongyi's problem-solving process was simpler than the "standard answer", saving at least several steps. It can be said that Liu Hongyi gave the best way.
