Chapter 58 Science in the Mortal World
Sun Zecheng stood silently for a long time, his eyes on his toes. Now he didn't dare to look at Nie Ying, for fear that he would change his mind after just one look at her.

Nie Ying didn't say anything, just smiled at Sun Zecheng.

“Actually, I’m a rotten person.”

Sun Zecheng finally left this sentence and left
Nie Ying was left standing there confused, why did Senior Brother Sun suddenly say that he was a bad person?
……

Sun Zecheng walked into the Huangfeng Valley Market, first went to the weapon refining shop to get back the piece of black iron, and then ran to Wanbao Tower to buy a top-level magic weapon that could hold water and wine.

The deacon disciple took out wine gourds, each of which could hold three thousand kilograms of water. There were two in stock in total, and Sun Zecheng took them all. Relying on his old relationship, he continued to sell them at the internal price, with the retail price being 200 yuan each, a total of 400 yuan, and the internal price being 360 lower-level spirit stones.

Well, there is nothing to buy here in Huangfeng Valley Market.

After leaving the market, go to the Spirit Eye Spring to fill up the wine gourd first. Then, the next stop is Yuanwu Country, the Tianxing Sect secret shop.

Sun Zecheng walked into the secret shop with ease.

"Boss, give me some directional teleportation talismans." Directional teleportation talismans are good things, and Sun Zecheng plans to buy a few more.

"Sir, our elder wants to see you. Please follow me."

Damn, I just want to buy some things, do I have to meet your elders?
However, the shop owner did not seem to ask for Sun Zecheng's opinion. He turned around and went in through the small door behind the counter.

Go through the small door and into the inner room.

Sun Zecheng touched the Taoism talisman on his wrist and another one hanging around his neck. He also walked through the counter and entered through the small door behind it.

Go through the small door and into the inner room.

A thin man in black was already sitting in front of a simple square table, and the shop owner was standing beside him respectfully.

The man in black did not hide his cultivation level. Sun Zecheng could clearly sense that he was at the Jindan stage. Damn, I wonder how much damage the Tao Talisman can block to the Jindan stage.

Like the shop owner, the men in black had no expression on their faces. Sun Zecheng suspected that they were actually wearing human skin masks.

Seeing Sun Zecheng come in, the man in black gestured to Sun Zecheng to sit opposite him.

Sun Zecheng sat down as he wished.

"This is the second time you've come to buy a directional teleportation talisman. The last time was only about half a year." The man in black spoke. His tone was flat and his accent was special, just like the shop owner.

"We buy it to use it. If I buy more, you will earn more, right?" Sun Zecheng was a little surprised.

"I think we are probably the same kind of people." The man in black said in a flat tone.

What do you mean? Sun Zecheng looked at the man in black without saying anything.

"Are you interested in joining us?" the man in black invited.

"I don't know, and I'm not considering it for now." Sun Zecheng said succinctly. "In fact, our good things are not for sale. You can only earn points by completing tasks and exchange them with points." The man in black was very calm, as if Sun Zecheng's answer was already expected by him.

Sun Zecheng said nothing and just listened quietly.

"For example, the directional teleportation talisman. The original intention of selling it is to find and identify people of the same kind. It is difficult for ordinary people to use two, and you bought five in such a short time. So we think you are the same as us, and you are born to do secret things."

"Directional Teleportation Talisman, we can sell you two at the end. From now on, you can only exchange them by completing quests."

"Okay." Sun Zecheng did not mention any other requests. Buying things is one thing, joining is another. Since he did not plan to join, Sun Zecheng did not intend to expose his intention to explore the ruins maze in front of the secret store Jindan.

Pay twelve intermediate pieces and get two directional teleportation talismans, a total of four. These are all the teleportation talismans if you don't plan to join the secret shop.

Sun Zecheng collected the teleportation talisman and left the secret shop.

After Sun Zecheng left the secret shop, Hei Yi Jin Dan asked the owner, "What do you think?"

The shopkeeper replied respectfully, "Elder, the things this person bought were all used for his dark business, and he clearly had no intention of joining us. He obviously has another way to make money, most likely he discovered some ruins and treasure."

"Hmm" the man in black snorted and took out a small copper bell magic weapon and handed it to the store owner: "Give this to the Black and White Impermanence, and let their brothers follow him and catch him when they get a chance!" After the store owner took the order and went out, the black-clothed golden elixir soon disappeared from its original place.

……

Sun Zecheng left the secret shop, thought for a while, changed his clothes in a deserted place outside the market town, and re-entered the market town, heading straight for the Stardust Pavilion of the Tianxing Sect.

"My dear senior, the first to third floors are for Qi Refining disciples. I'm afraid there's nothing suitable for someone like you. The fourth to sixth floors are for Foundation Building seniors like you. Please go upstairs." Seeing Sun Zecheng, who was at Foundation Building stage, strolling around on the first floor, a clerk came over to greet him.

We can’t use low-level stuff to build our foundation? Low-level stuff is useless to high-level cultivators? What a prejudice! Flexible use of low-level stuff is actually a science! But Sun Zecheng was too lazy to explain this to the clerk.

"We'll go up to the fourth floor later. What are those cheap, simple and fast formations on the first three floors? Pick them out for me! I must choose the ones that are simple and fast to use!"

I met a poor guy who was already building his foundation, but he still bought the cheapest things for the Qi Refining Stage! The clerk secretly despised Sun Zecheng in his heart, but Sun Zecheng's transaction on the first floor was considered his sales performance and was good for him, so the clerk despised him in his heart while quickly taking out three sets of formation tools and placing them in front of Sun Zecheng to introduce him.

The clerk took out a set of five small flags covered in thin white mist and introduced: "This is the simplest enchanting formation. It is also simple to set up. Just insert the flags and you're done. You don't even need a formation plate. You can just pinch the spell to control it. Each flag is driven by a low-level spirit stone. It can last for half a year, but it can only confuse and stop mortals or ordinary beasts. Immortal cultivators will break it with one strike, just like paper."

The clerk picked up a set of five small flags covered in thick mist and introduced: "This is the Water Moon Illusion Formation, which has the Water Moon Illusion Technique. The formation can be set up by inserting the formation flags. There is no need for a formation plate. It can be controlled directly by pinching the magic formula. Each formation flag is driven by a low-level spirit stone. It can last for four months. Generally, Qi Refining disciples can be trapped in it for a while. The specific situation varies from person to person. Of course, after the confused cultivator wakes up, he will be as fragile as paper and will be broken in a few hits."

The clerk picked up a set of ten small flags covered in earthy yellow mist, a formation plate, and a jade slip and introduced them, "This is the Yellow Sand Illusion Formation. The formation plate is needed to set up and control the formation. The specific formation setting and control methods are in this jade slip. Each formation flag is driven by a low-level spirit stone and can last for three months. Even a disciple in the late stage of Qi Refining with a top-level magic weapon can resist for more than an hour."

"The Maze Formation is a low-level formation of twenty-five pieces, the Water and Moon Formation is a low-level formation of thirty-five pieces, and the Yellow Sand Formation is a low-level formation of two hundred pieces."

Consuming five lower-level spirit stones can resist the attack of a late-stage Qi Refining disciple with a top-level magic weapon for more than an hour! The cost-effectiveness of this formation is unreasonably high! This was Sun Zecheng's first reaction after hearing the introduction.

Sun Zecheng immediately thought of the original novel in which Han Li, after building his foundation, took the semi-finished Reversed Five Elements Formation made by Qi Yunxiao and Xin Ruyin. With one tenth of the power of the finished product, a few mid-level spirit stones were able to withstand the bombardment of dozens of foundation-building puppets of the Qianzhu Sect for half a day. This was totally unreasonable, and it did not conform to the law of conservation of energy, and it was completely inconsistent with the science of the real world.

However, now that people have traveled to this mortal world, what they need to do is not to investigate whether it conforms to the science of the real world, but to look for and discover the irrationality of this world and use this irrationality, such as BUGs, to obtain the maximum cost-effectiveness.

This is science in the mortal world!
