For example, people from Lin Zhenhua's era got married very early, and now even their grandchildren are married, including the granddaughter of a female welder named Shen Jiale.

Over an hour later.

Two business cars arrived outside a massive industrial park.

Passing through the routine security checkpoint, the two cars continued straight ahead, eventually stopping around a group of research-oriented buildings.

"Dr. Xu."

After getting out of the car.

Zhao Haiyang pointed at the surrounding buildings and introduced them to him:

"This is our Han Hua Heavy Industry's R&D center. A bit further back is the group's office area. Director Lin should be... uh, Director Lin?"

As Zhao Haiyang spoke, he suddenly froze.

His gaze was fixed on a particular direction, and the rest of his words got stuck in his throat.

Xu Yun blinked, then suddenly realized something.

He turned his head to look in that direction.

And at that moment.

A few dozen meters away, an elderly man was slowly approaching with several assistants.

The elder appeared to be in his seventies, with gray hair but a full face, sharp eyes, and a vigorous spirit.

His skin exposed to the open air was darker than that of ordinary people, clearly showing he was an old hand at fishing.

Xu Yun had once seen a photo of this man in Tian Liangwei's phone album. This straight-backed little old man was none other than...

Lin Zhenhua!

Coming to his senses.

Xu Yun quickly signaled to the others and briskly walked up to meet the elder.

Standing before Lin Zhenhua.

Xu Yun stopped and respectfully bowed to him:

"Hello, Elder Lin!"

Lin Zhenhua patted his shoulder, then looked Xu Yun up and down:

"Young man, are you Old Tian's student?"

Xu Yun smiled and nodded:

"I am Xu Yun. My teacher was kind enough to take me under his wing, and I'm about to graduate soon."

"By the way, Elder Lin, why did you come out personally? Weren't we supposed to meet in your office?"

Lin Zhenhua casually waved his hand, suddenly exuding a bit of sharpness:

"I heard from Old Tian on the phone that your company is now facing attacks from both the little devils and the foreign devils, a pretty big situation."

"For those who dare to fight the devils with bayonets, even these old bones of mine must come out to greet them."

He then glanced at Old Su and others behind Xu Yun, asking:

"Xiaoxu, do you want to rest at the guest house first?"

Xu Yun was slightly taken aback but quickly understood Lin Zhenhua's intention and immediately said:

"No need, Elder Lin. Time is tight now. If it's convenient, let's head to the lab now."

Lin Zhenhua laughed heartily, patted Xu Yun's shoulder again, and signaled to the staff next to him to take the luggage.

Then he turned and pointed in a direction, saying:

"Alright, let's go to the lab first!"

Then, led by Zhao Haiyang,

the group walked straight for a few hundred meters, crossed several buildings, and finally arrived outside a single-story building.

"Everyone, this is our comprehensive research center."

Zhao Haiyang pointed to the entrance of the building, straightened his body a bit, and proudly introduced: 𝗳𝚛𝗲𝕖𝚠𝚎𝚋𝗻𝗼𝕧𝗲𝐥.𝚌𝚘𝐦

"This is also our group's Number One Research Center. The development of the five-leaf electric fan that laid the foundation for Han Hua Group took place here."

"Though decades have passed, the equipment of the research center has been updated iteratively, and people have changed time and again, the spirit of our predecessors has been continuously inherited."

"The country's first set of two million-ton ethylene equipment, the first million-ton hydraulic press, their practical design drawings were all produced here."

Xu Yun and others, upon hearing this, immediately showed a hint of admiration.

This practice of retaining a laboratory's 'designation' is quite common in the country.

For example, the renowned Sinopec.

The laboratory where their first oil pump was developed has also been preserved and still maintains high output.

And there's the Zhongjing Medical Laboratory in the Central District of Ke Da.

It was the first medical lab established after the Southern Relocation of the Science and Technology University, and it still exudes astonishing vitality to this day, with a Lancet paper published just last year.

Then Zhao Haiyang opened the electronic door and led everyone inside.

The Number One Research Center, although only one story, covered an area of ten thousand square meters, roughly a 100x100 specification.

After putting on the lab coats.

Lin Zhenhua replaced Zhao Haiyang's role and guided everyone into a deeper lab.

At this moment, there were seven or eight researchers busy in the lab. Seeing Lin Zhenhua and his group appear, one of the men turned to instruct the others.

Next, he quickly walked over to them and greeted Lin Zhenhua:

"Hello, President Lin."

Lin Zhenhua nodded and turned to introduce to Xu Yun:

"Xiaoxu, let me introduce. This is Yu Yuanyong, the chief engineer currently responsible for our chemical project at the plant."

"The Sharpless Asymmetric Epoxidation technology Old Tian saw on the Sui Ren Website was a breakthrough accomplished by Xiao Yu's team during the research."

Xu Yun immediately extended his hand upon hearing this:

"Hello, Researcher Yu. I'm Xu Yun. Please take care of me."

Yu Yuanyong's complexion was somewhat dark, but he was quite outgoing, cheerfully shaking Xu Yun's hand:

"Dr. Xu, I've heard a lot about you."

Xu Yun awkwardly shook his hand, a trace of confusion flashing in his eyes, not sure if he was being polite or sincere.

Although Yu Yuanyong was a science student, he had quite extensive experience and immediately noticed Xu Yun's confusion, quickly adding:
