A professor's rebirth: I entered Tsinghua University in 1977.

"teacher……"

Director Song was very excited to see Tan Dexi again. He personally stepped forward to open the car door for Tan Dexi, saluted him with his hand, and tears in his eyes.

During the two years that Tan Dexi worked at Yanggou Farm, although Director Song did not visit him personally, he entrusted someone from the factory to visit him twice and brought him some gifts.

Director Song had no choice but to do this.

As the Party Secretary and Director of Factory 576, he had to be particular about many things.

Given Tan Dexi's current status, it wouldn't be a problem for ordinary factory workers to visit him and bring him some gifts. Even if someone were to hold a grudge, Song Anhua could find a way to protect him.

If others target Song Anhua directly, who will protect him?

Song Anhua was naturally very surprised when Tan Dexi suddenly came back.

Holding Song Anhua's hand, Tan Dexi was also very excited. He looked at his student and sighed, "Anhua, you have white hair too."

Song Anhua raised his hand to wipe his eyes and said with a smile: "Teacher, do you think I'm still young? I'm almost fifty years old..."

He is actually forty-three or forty-four years old, about ten years younger than Tan Dexi.

"Okay, we can talk about family matters later, let's talk about work first."

"These are comrades from the research institute. Go to the office first and call so-and-so, so-and-so, and so-and-so to come together for a meeting!"

The people Tan Dexi mentioned were all technical backbones and production managers in the factory.

Song Anhua agreed repeatedly and gave the order immediately.

Soon, a work meeting was held in the small conference room in the factory.

Besides the colleagues from the research institute and the few people Tan Dexi mentioned, Wang Zhigao and another deputy director who was on good terms with him also came over.

Tan Dexi didn't give them any face at all and said with a stern face: "What are you doing here?"

"This is a technical meeting, what do you know?"

In addition to contempt, there is also vigilance.

The 35mm automatic grenade launcher is a relatively new weapon worldwide. Apart from the United States, Russia, and a few major Western powers, no other country has even seen it.

Confidentiality is very high.

Tan Dexi didn't trust either of them at all.

They are all uneducated and unskillful guys who only want to create chaos in the world.

All they do is cause destruction and mess things up recklessly.

Wang Zhigao sneered, stiffened his neck, and said, "What a joke! I am the number one deputy director of Factory 576. Why can't I attend factory meetings? What right do you, Tan Dexi, have to lecture me?"

"Nonsense!"

Without waiting for Tan Dexi to speak, Song Anhua started yelling angrily.

"Wang Zhigao, don't talk nonsense."

"Who is talking nonsense?"

"Tan Dexi is no longer a member of Factory 576!"

Song Anhua shouted, "Teacher Tan has been assigned to our factory by higher authorities to oversee the trial production of new weapons. He's a senior engineer. Director Duan called him personally, so don't mess around!"

Wang Zhigao paused for a moment, then said, "Then let me ask you, I am the deputy director of the factory, why can't I attend factory meetings?"

He insisted on this point, and Song Anhua was unable to refute him for a while.

Indeed, even for a classified mission, unless there are explicit orders from superiors, it is impossible to avoid him, the factory's deputy director and second-in-command.

"Okay, Anwar, let them participate."

Tan Dexi didn't want to waste time on this matter. He couldn't really kick Wang Zhigao and the others out anyway. Otherwise, if they started making trouble, it would definitely affect the subsequent trial production tasks.

"However, Wang Zhigao and Jiang Guoyong, let me tell you, today's trial production of this new weapon is a classified mission. No one is allowed to leak it! Whoever leaks it is a bad element and will bear all the responsibility!"

"When the higher-ups come to investigate, no one will be able to protect you."

Tan Dexi's stern face and his intimidating words made Wang Zhigao and Jiang Guoyong quite nervous.

Ultimately, they were just two ordinary workers whose experience and knowledge couldn't compare to that of real factory leaders.

However, he still stubbornly refuted Tan Dexi a few times, then sat down aside and said nothing more.

"Liu Hongyi, let's put on the slides and you will be in charge of explaining them."

This is Tan Dexi's style. There is not even a word of nonsense. He skips the opening remarks and goes straight to the technical level.

"Okay, teacher!"

Before coming, they had already rushed to produce the slides at the research institute, and some necessary preparatory work had also been completed in advance.

The technicians in our own factory are responsible for debugging the slide projector.

The curtains in the small conference room were drawn and the lights were turned off.

Liu Hongyi inserted the slides into the machine and started playing. Then, holding a long pointer, he explained the design principles of the 35mm grenade launcher to everyone.

Tan Dexi had his considerations when letting Liu Hongyi, a sixteen-year-old high school student, be in charge of the explanation.

On the one hand, this was Liu Hongyi's design, and his thinking was clearer than anyone else's. On the other hand, it was also a further training exercise for him. Tan Dexi was prepared, ready to provide supplementary support if Liu Hongyi got stuck.

Unexpectedly, this situation never occurred.

As soon as he put on the slides and picked up the pointer, he stood in front of the whiteboard, and his aura of a second-level professor was immediately on full display.

He spoke standard Mandarin from beginning to end, fluently and without a single stutter.

It's as if he was born to be a teacher.

The more Tan Dexi listened, the more he liked it.

Liu Hongyi's explanation is much more detailed than the reference material. Many details are not in the reference material, and are supplemented by his oral explanation.

Yuan Gang, Jin Yunfeng, Zhang Chenghai and others were even more stunned.

They had already experienced Liu Hongyi's prowess and knew he was very skilled, but they had never imagined his skill would be this high. It seemed he was not much behind Teacher Tan.

Although the 35mm automatic grenade launcher was almost a completely new field for them, they understood it without much difficulty under Liu Hongyi's explanation and with the help of slides, and had basically no questions.

It is impossible for ordinary teachers to have this level of teaching.

Even during the heyday of their institute, when those top researchers were still there, the technical level was indeed very high, but no one could compare to Liu Hongyi in terms of teaching level.

It is possible to explain complex technical designs in such a clear and understandable way.

Looking at the technical backbones and production managers of Factory 576, they were all listening attentively, with no doubts or confusion at all. During the whole process, few people asked questions.

It can be seen that they have completely understood it.

"Comrades, the 35mm automatic grenade launcher is a new type of weapon. Our factory is manufacturing the prototype, which is an honorable task. I hope everyone will do their best to complete this glorious task with high quality and quantity!"

"Do you have confidence?"

The last person to make the summary was naturally Tan Dexi.

"Have!"

The answers from everyone in the conference room were resounding and powerful.
