Let's turn the time back to December 05, 2638 in the Douluo calendar.

"Xiaoyou, do you really want to use this money like this?"

On the way, Tang San had a difficult look on his face, and asked Gu You, who was holding a sugar gourd beside him, with a nonchalant expression.

"What's wrong, it's going to be used anyway."

"Ah, here it is."

Tang San raised his head and was silent as he looked at the three-story building in front of him, which was full of all kinds of colorful life soul guides.

You must know that the Martial Spirit Hall of Notting City is only three floors, and the City Lord's Mansion is only three floors. Just a shop selling soul guides dared to build three floors, how valuable this thing was, Tang San couldn't even think about it.

"It's my first time here, and I don't know what it's going to sell."

Because he has no money, even if Gu You knows that there is this place, he has never been here. Looking at the billboard on it, which is no different from modern society, it is printed with five big characters of "Soul Guide Store", and even shines a spotlight on the word.

For a moment, Gu You felt as if he had returned to modern society, and was about to enter a certain supermarket to make a big purchase.

Retracting his mind, Gu You beckoned Tang San to go in together.

The entrance to the door was very smooth, and there was no story of any aristocratic evil young man jumping out to block the road, and then Gu You slapped his face. In this regard, Gu You expressed great regret.

He didn't want to think about how many times the city lord's son was still Xiao Wu's younger brother in the academy, and how many times he had been in and out of the Martial Spirit Hall with this face, how could anyone dare to block the way.

As soon as he entered the door, Tang San was stunned by the prosperity inside, as if ancient people had traveled to modern times, all kinds of strange objects were placed on the counter, but Tang San couldn't see the principle of use at all.

Gu You was much calmer, and only showed a hint of nostalgia in his eyes. He traveled through the previous world, and he had never seen anything magical.

Just the various soul guides that can be seen now, such as the soul guide lamp that resembles an electric lamp, the soul guide pot that resembles a hot water kettle, and the soul guide fan that resembles an electric fan、.........

There are all kinds of things that can be found in the previous world, and they are better and more elaborate, and they don't even need to use supernatural powers.

In the past, human beings in the world did not have extraordinary powers, and they were able to fly into the sky, break through the atmosphere to reach space, and even go to other planets to explore. It took only 5,000 years at most from the beginning of the establishment of civilization.

The human beings in this world have extraordinary strength, even if they don't consider how long the history of the human race was before Tang San crossed over, only considering the time of 10,000 years after Tang San crossed over, none of the humans on the Douluo Continent broke through the atmosphere.

For 10,000 years, no human being has wanted to use his extraordinary power to explore the world and find the truth, all of which is used to fall in love or fight and kill.

Guyou does not deny the power of battles and wars to human technology. After all, objectively speaking, it is true that a large number of science and technology were successfully developed for the war at the earliest, and only after the war was over, but they were used in the field of people's livelihood.

The most famous is nuclear power, a nuclear power plant built in a peaceful society that was used as a nuclear bomb in war.

But after so many years of fighting and killing in Douluo Continent, there has been no leap forward in technology, which is what Gu You can't imagine.

There is also Qiandaoliu, which is the strongest in the sky, and you said that you are the strongest in the sky, don't you wonder what is above the sky, and don't you challenge yourself to how high you can fly?

Or is there a scorching void in the atmosphere here, which will hit everyone who wants to rush out of the planet and into the universe?

Well?

It seems impossible to think about it.

There is no Lie Empty Sitting in the Douluo Continent, but there are gods, and gods are not used to do this.

Thinking of the future god realm falling into a black hole, and the scientific and technological level of human beings rushing into space by leaps and bounds, Gu You always felt that he had discovered something Huadian.

I wouldn't have been found dead by being shot eight times in the back early the next morning.

"Xiaoyou, what's that?"

Gu You came back to his senses and saw Tang San pointing at a strange soul guide, his eyes shining.

"That's water...... Soul guide pump, a kind of soul guide used to transport water. ”

Hearing Gu You's answer, Tang San asked in surprise, "Isn't it a water pipe that is used to transport water?" ”

Gu You almost blurted out "how to deliver water through the water pipe", but in retrospect, with Tang San's lifestyle, he really shouldn't know what the water was transporting.

In the Holy Soul Village, there is no such thing as a soul guide at all. First, the soul guide is very expensive, and the cheapest soul guide lamp requires two gold soul coins, and the people in the village can't afford it at all.

Second, the operation of the soul guide requires soul power, and at that time, no one else in the village had soul power except Tang Hao, so it was impossible to let Tang Hao help fill the soul power.

When we got to Notting City, there was a faucet in the academy, and then the water pipe was pumping from the back of the academy. But Tang San wouldn't specifically follow the water pipe to see where the water came from, and it was normal to not know what a water pump was.

Gu You originally wanted to talk to Tang San about the working principle of the soul guide pump, but he thought that he didn't really know whether the soul guide pump was the same as the water pump in his previous life, so he still kept his mouth shut, saying less and making fewer mistakes.

It's all used soul power, and the ghost knows if it's pumped up under pressure or the soul power is scooped up little by little inside.

The most basic principle of an electric kettle is that an electric current generates heat through a resistor, and the water is boiled with heat, which is called electric heating. The principle of electric lamp is that the current passes through the tungsten wire, and the energy of the tungsten wire increases after heating, and the heat lost after the energy naturally decreases is converted into light, that is, electricity generates heat and light.

But this is a fantasy world, and maybe some scientific principles can be copied into it, but even if the phenomena are the same, the operating logic of most of the principles is essentially different.

Gu You can be regarded as a science student at most, and he is not a big man, let alone a big man in scientific research. It was hard for him to explain why his soul power could turn into heat or glow through the soul guide.

"Little San, are you interested?"

"Of course."

Two words can express Tang San's current mood, that is, curiosity.

Tang San dared to steal the inner door exercises and secret weapon Baijie as an outer disciple, and successfully created the hidden weapon Buddha Fu Tang Lian that no one could reproduce again, which proved that Tang San had extraordinary curiosity and extraordinary hands-on ability.

As a science student, Gu You can give theoretical guidance. Naturally, an engineering student is needed to turn theory into practice.

During the Douyi period, who is the most suitable engineering student?

There was no one else except Tang San.

Tang San, who had already come to the end of the hidden weapon, urgently needed a new path to carry forward his engineering ability, that is, the soul guide.

Gu You, who has the knowledge and logical thinking ability that surpasses everyone, plus Tang San, who has the strongest hammer in the contemporary era, is definitely the most suitable soul guide research combination.

Using Tang San's experience to disassemble the soul guide, and then using Gu You's logical thinking to judge the role of the internal structure of the magic circle, and then combining the various magic arrays, you can create the strongest secret weapon after evolution.

Well, just use this reason to let Tang San work overtime. Gu You thought silently.

Soul guide, Gu You believes that this is the power that truly belongs to all human beings, and the only way to let human beings move towards the future.

Gu You, who comes from modern society, never thought that martial spirits could make human beings progress. Maybe some people can do things that soul guides can't do with powerful martial souls.

However, it is only the strength of the individual, and it is meaningless to the entire human society. Not to mention that if you become a god, then there is really nothing left for mankind.

The original Shrek Seven Monsters all became gods, but will future humans receive the favor from God and live a happier life?

No, not only not, but for most ordinary civilians, they have even lost their ascent channel, and they have no chance to change their fate (awaken the martial spirit).

Even Shrek Academy has changed from an academy that recruits civilian geniuses to a pure aristocratic academy that requires a letter of recommendation from nobles.

After all, Shrek Academy may not have been a civilian academy in the first place.

The original Shrek Seven Monsters,

Dai Mubai, the prince of the Star Luo Empire.

Oscar, civilian.

Tang San, a descendant of Haotian Sect.

Ma Hongjun, civilian.

Xiao Wu, a soul beast adult.

Ning Rongrong, the heir of the Seven Treasure Liuli Sect.

Zhu Zhuqing, a member of the Zhu family of the Star Luo Empire.

Two-sevenths of them are civilians, and perhaps it was at this moment that made Shrek Academy taste bad, and it also made the original Lanba Academy taste bad.

Martial soul and innate soul power look at the bloodline, and the soul guide research does not look at the bloodline. The action of turning on the lights will not be turned on just because you are a nobleman with soul power, and civilians will not be able to turn on the lights without soul power.

From the soul guide lamp in the academy, Gu You knew that the current soul guide has a milk bottle installed, but it is not a sealed milk bottle.

In the future, Xuan Ziwen of Dou Er can make a sealed milk bottle, there is no reason why I can't do it.

In addition, I have Admiral Tang San, who can play and output when he enters, and can be a wet nurse when he retires. Gu You didn't believe that he couldn't reproduce the soul guide civilization in the Douluo Continent.

Some people may say: Why don't you use electricity, electricity is not better than soul power.

Yes, electricity is indeed easier to use than soul power, and it is more versatile.

But this is the Douluo Continent, and the ground under his feet is still made of the corpse of the Mountain Dragon King. Gu You didn't think that this thing could also produce the most important coal and oil in the industry.

Maybe in the future, when the soul guide civilization is really successful, Gu You will start to think about wind power or hydropower, so let's pull it down now.

Gu You beckoned Tang San to leave quickly, "Little San, let's go, our goal today is to spend all this money." ”

"Didn't we come here to buy some soul guides to put at home?" Tang San was shocked, it was enough to spend money to buy a small house with a garden in the city, but it was only a drop in the bucket for 100,000 gold soul coins.

Gu You plans to spend the rest of the money here, is he going to empty this place?

"Just kidding," Gu You sneered, and he also decided that it was unlikely.

"In addition to buying some necessary soul guides, such as soul guide lights (electric lights), soul guide pots (hot water kettles), soul guide cabinets (refrigerators), and soul guide pumps (water pumps), you also have to choose some soul guides that you are interested in, and I will buy a few copies to go back."

"How many copies to buy?" Tang San was puzzled, it was understandable to choose some that interested him, but why should he buy a few copies.

"Little San, aren't you curious why it glows?" Gu You pointed to the soul guide lamp that emitted a soft light next to him, and gently leaned into Tang San's ear and said.

"Why does it glow when it enters soul power? Why is it left for a while, even if you don't use the soul power in it, it will dissipate? Why is it that no matter what color the soul power is infused into, the color of the light emitted is the same? ”

"You're not curious about these questions at all?"

Just as a viper tempted Eve in the Garden of Eden to eat the fruit of wisdom, just as the devil tempted Faust to pursue happiness.

Gu You always thought that it was much better to use a hammer for forging than to smash people. I have never figured out why the hammer appeared on Tang Wutong, who had never forged, instead of Tang Wulin, who obviously needed and was more suitable for the hammer.

Even Haotian Sect, a sect whose martial soul is a hammer and has produced several generations of divine craftsmen, did not appear in Dousanli.

Gu You's words also quietly aroused Tang San's long-dormant desire to explore.

"But there's no need to buy a few copies to go back, just buy one." Tang San spoke with difficulty, reason suppressing curiosity.

This is the money that Gu You used to buy a house and live together is already a favor, and the soul guide installed at home can barely be said to be used by Gu You himself.

But in order to satisfy his curiosity, let Guyou spend money? Tang San thought that he couldn't do this kind of thing, so he should wait until he worked in the blacksmith shop and made money before coming over to buy it.

"Can you hold back?" Gu You didn't expect Tang San to be able to suppress his curiosity, after all, in the original world line, he was a strongman who hollowed out other people's medicine gardens.

It seems that the inculcation of values is still useful! Gu You was complacent. It's just that Gu You doesn't need Tang San to have such a high moral standard, and the kindness of the "big brother" still has to be accepted well, so he decided to add another fire.

"You don't want to make a stronger secret weapon? After mastering the principle of the soul guide, it is possible to use it on the hidden weapon to make the hidden weapon more powerful. ”

“！！！” This sentence completely crushed Tang San's mental defense.

Gu You only felt that with Tang San's curiosity and ...... to the Tang Sect In other words, the feelings of the secret weapon can allow Tang San to study the soul guide.

But he didn't expect another possibility at all, that is, Tang San originally had the idea of surpassing the Tang Sect's secret weapon.

Tang San was only 30 years old when he completed the highest masterpiece of the Tang Sect's machine bracket hidden weapon, which happened to be the period when he was young and middle-aged and most energetic.

The secret weapon that no one can reproduce, Tang San can complete it at the age of 30, and it is not even discovered, Tang San still has the possibility of further improvement. But Tang San could only choose to commit suicide by jumping off the cliff, making all this empty talk.

And now, Tang San had a chance, a chance to surpass the Tang Sect's secret weapon and push the secret weapon to a new apex.

The soul guide can do many things that are impossible in Tang San's opinion through soul power (which is also internal force for Tang San). Glowing, boiling water, freezing、...... These are all things that ordinary soul power can't do.

"As long as I learn the principle of the soul guide and use it in the manufacture of hidden weapons, I will be able to make a soul guide hidden weapon that only belongs to me Tang San!"

Tang San's heart was surging, and he wanted to go home to study it now with the soul guide, but the only remaining reason told him that he couldn't do this.

At this moment, Gu You added: "I also happen to want to study the soul guide, but I can't be busy alone, Xiao San, can you help?" ”

Do you still need to think about this? That's it.

Tang San only replied with one word: "Okay." ”

PS: The little theater that came to mind when I wrote this chapter

Tang San in this book: There is a limit to the power of hidden weapons, and the more you pursue pure hidden weapons, the more hidden weapons will be limited because of the existence of the Tang Sect.

Poseidon Tang San: What are you talking about?

Tang San in this book: I want to surpass the Tang Gate now!

Take out the new Soul Guide

Seagod Tang San: Brand new secret weapon, why do you have this!

God of War Dai Mubai: Quickly defeat him.

Tang San in this book: Poseidon! Just use your blood!!

I found that I was too easily influenced by comments, but I couldn't help but want to click on the comments, which made my mood go from good to bad. Ask for a recommended ticket and ask for a monthly pass~~
