The righteous spirit, like a pillar of heaven, radiates dazzling light.

Almost everyone present was seeing such a powerful and righteous aura for the first time, and they immediately let out a series of exclamations.

"Is this what they call righteousness?"

"It's indeed pure enough! This is the feeling, the righteous energy of heaven and earth! Excellent!"

Some of the bolder martial artists even went so far as to approach inside and try to touch it.

Ju Mang Zhong, who was in the center, was somewhat unable to move. Although he had no evil aura and would not be suppressed by the righteous energy, the weight still made it impossible for him to stand up straight.

"Ah! Such powerful righteous energy—" Jumang Zhong roared, about to unleash the power within his body to resist.

Seeing this, Lin Che simply stopped in time, without suppressing all of the righteous energy.

With a whoosh, the righteous energy was withdrawn, and immediately, a dissipated righteous energy drifted between heaven and earth.

Countless martial artists watched, and another cheer erupted.

Big Elbow watched from behind, filled with admiration: "So our boss is this amazing. I must train hard!"

A strange expression appeared on Danqiu's beautiful face. In her eyes, Lin Che radiated light and was full of mystery. At such a young age, facing the Medicine King, the three Jumang brothers, and millions of martial artists, Lin Che showed no fear whatsoever.

In front of these world-renowned figures, Lin Che chatted and laughed with ease; no other young man was as spirited and confident as him.

"There are still such men in this world!"

Amidst the cheers of the crowd, Lin Che had already become familiar with the sect leaders of the Eight Gates of the Divine Palace.

Jumangbo extended an invitation: "Hero Lin Che, you are indeed incredibly capable. You are qualified to join our Divine Palace Eight Gates and become a sect leader."

Becoming the sect leader is out of the question.

Lin Che knew very well that his purpose in coming here wasn't really to make a name for himself. He wanted to go back. Moreover, he had already cultivated eight different techniques, and whether becoming the first sect leader would cause any reaction was unknown.

Lin Che stated bluntly, "I have no ambition to lead the heroes of the world. The position of sect leader is more suitable for the Medicine King, and it is also the popular choice. I prefer to invent useful things that can benefit our human race."

Jumangbo tried to persuade him further: "It's alright, the Divine Palace has eight gates, each with a gate master, and both of you can join..."

"Why don't you all take a look at my invention first?"

Lin Che didn't care whether they agreed or not; this was a rare opportunity.

He took out the wall clock that he had prepared beforehand, and gently lifted it up to hang it on the floor.

"Gentlemen, this is the clock I invented. It is used to calculate time precisely, more accurate than any sundial or water clock. What unites us humans? It is our way of life, our bloodline, and our shared values."

"Uh, Lin Che, what is a set of values?"

"That's not important!"

Lin Che then took out a second item, which he had refined in his spare time over the past few days.

"Gentlemen, apart from the clock, what I have in my hand is called glass. These are called mirrors—catch them, these mirrors can reflect your image."

Lin Che tossed a bunch of small mirrors into the crowd and then hung up one of the large mirrors.

This naturally caused another uproar.

However, aside from the novelty that these things fascinated the martial artists, they didn't seem to care much about them, since they weren't particularly useful to them.

Jumangbo also shook his head slightly: "Now that the demons have invaded our human territory, we should focus on cultivation. Once we defeat the demons, you can then tinker with these inventions in peace."

Lin Che was also prepared: "In order to deal with the demon race, I also invented cement specifically for building cities!"

Jumangbo pondered for a moment, then said, "The Myriad Demon Clan? Hmm, that's right. They can indeed be called the Myriad Demon Clan. What is this cement you're talking about?"

Lin Che led them to a high wall nearby: "Now, let me show you the amazing properties of this cement."

The high wall in front was the work he had Big Elbow do. It looks a bit ugly from the outside, but the stone, sand and cement were poured together, so you can imagine how hard it is.

More importantly, it can achieve a perfect fit.

"This is my latest invention, which will allow us to build taller buildings and taller city walls."

Jumang Zhong couldn't resist and stepped forward, stomping on the high wall with a loud bang.

But the comical scene didn't elicit laughter from the crowd; instead, it piqued the interest of many. Even Yao Chengxuan immediately squatted down, picked up a large chunk of cement, and examined it closely.

"This stuff is really good. It's comparable to stone. If we could use it on a large scale, we could indeed build a huge castle."

Jumangbo also picked up a piece: "I've always had an idea. Our human race has never had its own defensive line against the demons... that is, against the myriad demon races. Our human race needs to set up camps and build defensive arrays, which requires a long castle. This kind of cement is absolutely suitable for use! Lin Che, how much cement do you have?"

Lin Che immediately knew his opportunity had arrived: "You can have as many as you want, but I need to produce these things and I need capital."

"Capital? Hmm, sure. When we build a city, anyone who wants to live there should contribute. It's only right that they contribute some gold and silver."

With Jumang Bo's words, the verdict was practically finalized.

Lin Che knew very well that his grand plan to make a fortune was about to begin.

Once he earns money, he will gain skill points. After killing another batch of demons, he will be able to cultivate the power of cause and effect.

Three days later.

Lin Che's various great inventions began to emerge.

He couldn't possibly take action himself, but he happened to have people he trusted, so he entrusted them to Lai Jian and Dan Qiu to handle.

Various types of cement, glass, mirrors, coal briquettes, clocks, and so on began to circulate.

Mirrors were the most popular items among the women, followed by various briquettes, but the largest productions were cement and clocks.

Lin Che also employed various methods involving contractors, distributors, and franchisees, resulting in a daily influx of gold and silver. Perhaps people at that time didn't have much of a concept of gold and silver, and they were very generous with their spending.

[Congratulations, host, you have gained 20 skill points.]

[Congratulations, host, you have gained 130 skill points...]

The notification sound goes off dozens, even hundreds of times a day.

Finally, after just one month, Lin Che's skill points exceeded 100,000.

"Now, all that's left is the killing intent value!"
