Immortality, but people in primitive society

Chapter 417 My name is Zhang Hui

"Why does this thing go in and out during the day, and then it releases water?"

"This is called a piston, something that can do reciprocating motion..."

"Great, great. Piston, this thing is good, good..."

In the Jicheng Mechanical Institute, Bai Tian was slowly shaking the wooden piston he had just made, surrounded by a group of people watching.

Except for Nuying who had a face full of questions, everyone else's eyes were shining.

It has been more than half a month since Bai Tian came to the Mechanical Institute, and it took him almost three days to make this piston.

It's actually just a very simple piston mold, made of wood. I hadn't figured out how to apply it in practice during the day.

In fact, during the day, we have discovered that it is very difficult to truly realize industrialized machinery.

Jiuzhou has never developed much industry, and most people's minds are on cultivation. The technology tree is really too difficult to deal with.

Industrial development requires energy, and we cannot always rely on cutting down trees for energy.

Either coal mines or oil.

But I don’t understand these two things during the day.

During this period of time, I have been thinking about whether it is possible to use spirit stones as energy.

But every time he mentioned the Spirit Stone to Lao Tong and the others, they became very serious and told him not to mention it again. As for the reason, they were unwilling to say.

This made Bai Tian very puzzled. Why couldn’t the spirit stones be withdrawn?

According to my impression during the day, there should be spirit stones in Jiuzhou, but the number may not be large.

The spirit stones also grew with the spiritual energy of this world, starting from white ore, slowly becoming sky stones, and then becoming stable spirit stones. However, after the cultivation gradually stabilized, the number of spirit stones actually decreased.

Remember during the day, spirit stones usually appear in space channels, and dragons love to collect spirit stones the most.

As his strength grew over the years, he hadn't paid much attention to spirit stones. But he had learned from the Dao Sect that both Dao Sect and Yancheng were researching spirit stones. Why was it that they couldn't be mentioned in Jicheng?

Looking at the lively Lao Tong and others, Bai Tian couldn't help but ask softly: "Lao Tong, I still want to know why we can't use spirit stones?"

The smiles on Lao Tong and others suddenly disappeared, and their expressions became complicated.

"Alas," Old Tong sighed and explained in a low voice, "The city lord won't allow it. We in Jicheng once had a war over spirit stones, and many people died."

It was even weirder during the day: "Isn't this normal?"

Spirit stones are a kind of resource for those who practice cultivation, so conflicts are inevitable, which is reasonable.

As early as the Donghuang period, Bai Tian heard Donghuang say that some people fought for spirit stones.

"It's not normal." Taifu took over the conversation in a low voice, "Because of the fight for the spirit stone, three thousand people died in Jicheng. I lost my leg in that fight."

"And the person who started the war was a bit special... He was Shaohao's son."

Bai Tian was stunned. Shaohao should be Ji Qingyang. According to the timeline, Ji Qingyang's son should be of the same generation as Zhuanxu. Zhuanxu was not young, so the other party should also be old. Why would they do this?

Bai Tian frowned and said, "Even if it's related to Shaohao, you wouldn't forbid us from mentioning it, right?"

"You don't understand." Lao Tong sighed, "Actually, that man was once the best person in Jicheng. It can be said that he contributed to the success of Jicheng today."

"But he's always been resistant to Zhuanxu's leadership and has even battled the Heavenly Army before. I heard, but that's just hearsay. They say he discovered other uses for the spirit stones and wanted to use them to create another Heavenly Army to fight Zhuanxu. This sparked the worst conflict in Jicheng's history. It wasn't just three thousand people who died; it was three thousand future generations who perished!"

"So from then on, Jicheng is no longer allowed to study spirit stones?" Bai Tian frowned.

Lao Tong shook his head: "Not entirely, it's just that the spirit stones must be under control, and must be used for research on alchemy and refining, nothing else is allowed."

Bai Tian was even more puzzled: "That wouldn't mean you all look so grim..."

"Our Mechanical Institute was built by that person."

amount……

Now Bai Tian understood. No wonder the Mechanical Institute was so deserted and all the research was limited to wood!

Then again, he really didn't know this story during the day, and no one told him about it.

But no matter what, this doesn't mean we shouldn't study spirit stones. Spirit stones are the energy source of the cultivation world, and their use shouldn't be limited to alchemy and weapon refining.

It seems that I need to go to the City Lord's Mansion to find out more about the situation...

In the middle of the night, a man appeared silently in the city lord's mansion during the day.

During the time he had been in Jicheng, he rarely went out during the day and hadn't even been to the City Lord's Mansion. However, he could sense that Jicheng was actually quite depressing...

He landed in a yard and saw a room with light in it. He walked to the door and knocked gently.

"Who?"

"I'm going to find the city lord and want to find out some information from him..." Before Bai Tian could finish his words, the door opened and a cold murderous intent burst out.

Yeah, this guy is pretty awesome!

During the day, he stood still with a smile on his face. There was a brazier in the room, and next to it was a table. A middle-aged man was sitting at the table, looking very majestic.

The middle-aged man looked a little thin. He felt that he had seen him during the day, but he didn't have any impression of him.

After taking a quick glance, Bai Tian walked in with a smile on his face: "You should be the city lord, right? I want to find out something from you..."

"You...you are Haotian?!" The middle-aged man stood up suddenly, looking incredulous.

Then, he hurried forward and knelt on one knee: "Haotian lives forever!"

I felt a little helpless during the day. These four words really don’t sound very nice!

I should have changed it earlier. I didn't want to inherit these four words. They are too difficult to pronounce. Long live Haotian, Haotian is invincible, Haotian is really strong, all of them are fine...

After Bai Tian sat down, he said softly, "Sit down. By the way, what's your name?"

"My name is Zhang Hui, and my grandfather is Ji Xuanyuan."

Bai Tian was stunned: "Then why don't you have the last name Ji?"

Zhang Ban explained with a hint of embarrassment, "Well, I helped my grandfather defeat Chi You in the battle of physical strength and technique. So, he told me to change my name to Zhang Hui, saying that he wanted people with the surname Zhang to have more children, so that they would outnumber those with the surname Ji in the future."

What kind of idea is this? He wants his grandson to change his surname even though he has a job?

However, Bai Tian also knew that even now, people don’t really care much about names. Although most of the time sons take their father’s surname, there are also many cases where they take their mother’s surname, or even get randomly named.

Shaking off his thoughts, Bai Tian said, "I came to you mainly to learn about the spirit stone..."

Suddenly, Bai Tian thought of something and his cheek twitched. "The person we had an argument with before was your brother?"

"Yes, my second brother, his name is Ji Qiong..."

Jiqiong, Qiongqi, why do they sound so similar?
