"This ......" Ren Jian didn't seem to expect Lu Wu to reply like this. Although there was a small accident today, he didn't expect that it was not an accident, but an inevitability. "You're badly injured?"

"Nothing, skin trauma. The doctor said that he would just remove the stitches in a week. ”

"The doctor told you to avoid eating?" Ren Jian was a little puzzled. After all, in his opinion, Lu Wu doesn't have anything big at hand now, why don't he participate in the class reunion? Let's put it this way, Lu Wu's state at the moment can be described as a spring breeze (anyone who has a girlfriend like Amber probably can't be described in the second word), and the party is just right to show off. "It's hard for me to say this, and I didn't organize it. ”

This is very reasonable, before today, Ren Jian Ke was worried, and his spirit can be said to be extremely depressed. In this case, how can he still have the energy to organize a class reunion, organizing a memorial service is almost the same!" Someone should contact you at that time, you just have to talk to him yourself. ”

"Okay. Lu Wu replied.

He hung up. There was a nail on the wall next to the window, and after Lu Wu moved over, he hung a mirror on this nail. He came to the mirror. Perhaps because there are no lights on in the room (only the computer monitor is on), the eyes and hair in the mirror are as dark as night. In the depths of his eyes, there is a smile that comes from confidence.

This time he came back not simply to return to his hometown, in fact, the matter between him and Wa Ge has not been resolved...... It can be said that this time he and Amber are on an important mission.

Lu Wu didn't think anything about it before, but now that he settles down and thinks about it carefully, he will find that he has a golden finger that others can't even imagine.

A system of technology that is more developed, more mysterious, and more incredible than the earth. Or as it is now popular, it is called the tech tree.

First of all, Lu Wu knew that the technology trees of the two worlds were not exactly the same. According to the normal understanding (i.e., the understanding of technology by masters and warlocks), there will be great differences between civilizations, even if the technology level is similar. Generally speaking, there are very few things that are "ready to use", and they can only be encountered by chance. Between the technology trees of different worlds, the biggest use is to touch the bypass, and the so-called stones from other mountains can attack jade. It is necessary to know that there are actually two kinds of scientific and technological progress, one can be vividly compared to a "journey of a thousand miles", and the emergence of new technology is to point out a lot of pre-technology that looks ordinary but is actually indispensable step by step, or it is countless attempts, after a long period of experience accumulation, in order to finally get the result through trial and error, so as to light up the science and technology tree. The other can be vividly compared to "piercing the window paper", in fact, it is not impossible, but it is unthinkable. As long as someone's brain flashes, everything will fall into place.

For warlocks, the main purpose of obtaining technology from another world is to provide inspiration and new research directions for scientific research. Of course, in the "retreat" disciplines of philosophy and mathematics, the possibility of taking it is much greater.

However, Earth and Wago are the rare exceptions.

There are some places where the two worlds are incompatible, for example, there is an artifact such as the Resonance Stone in Wage, which is unheard of on Earth. Of course, this may be because Lu Wu didn't understand it in detail, if he had done a comprehensive understanding and analysis, he would probably find that there might be more than a resonance stone for incompatible.

So the two worlds can't really be said to be exactly the same.

However, even with these incompatibilities aside, there are too many things in the tech tree from another world that resemble Earth. In fact, the two tech trees were so close that Lu Wu could think that there were too many things to take and use.

Let's say, materials science.

As mentioned earlier, Lu Wu can be sure that the metallurgical technology of Wago is far above the earth. Among other things, the sword that Colonel Doyle gave him is the best example. The sword, according to the master's introduction, was made of a special metal produced under strong interaction, and it was extremely hard and almost indestructible, and the nano-coating on the blade, driven by enough force, would produce a very terrifying destructive power, compared to those melee weapons that had to carry their own energy.

Lu Wu once tried to use his sword to cut the exoskeleton armor (the main battle type, the one with heavy armor) in two, and there was no wear or chipping on the blade. He also tried to attack the sword with an electromagnetic cannon, and the end result was that although the sword was sent flying a long distance, it was intact and had no hole at all.

There's no such thing on Earth. What armor can hold off an electromagnetic gun?

The same is true for energy storage technology. It's hard to say exactly how people do it, but exotic cars can be driven for months without refueling (although they need to be maintained), rifles with their own energy can last a lifetime for soldiers, and of course other things. However, in this regard, Lu Wu felt that people might be involved in some elements that did not exist on earth. The last time he returned to Earth, he brought the Universal Rifle with him, only to find that it was immediately ineffective - he had to be thrown away as garbage. From this point of view, the energy storage technology of another world cannot be directly used.

However, the metallurgical side of the technology should be directly usable. Well, of course, metallurgy is just the beginning, and if you think about it carefully, there should be a lot of technology that can be used directly. Others may also copy the theory first.

If we can slowly introduce the technology of another world into this world, it should inspire a technological revolution. Of course, from the perspective of a Chinese, the biggest beneficiary of this technological change must be China. Lu Wu didn't want to spread those technologies for free, and as a result, foreigners would take advantage of it or something.

But after Lu Wu heard that Ren Jian had spent a lot of money to buy a steel factory that couldn't make money at all, he almost subconsciously thought of this.

If you have a steel mill, you should be fine. Starting from the metallurgical industry, an inconspicuous small and medium-sized factory, it has slowly led to the scientific and technological development of the entire human world......

Just thinking about it makes me feel emotional.

Of course, there is still the question of funding. After all, it is a very dilapidated steel mill, and it can even be said that it is completely out of step with the times. However, Lu Wu doesn't think this problem is too big.

Although the rules of the two worlds are different, they are mostly the same, and it can even be said that "most of them" are the same. Lu Wu himself is the best proof of this. The human body is made up of many elements, and it is clear that the absence of any one element can lead to immediate life-threatening conditions. Therefore, since Lu Wu can safely travel between the two worlds, it is obvious that all the substances that make up the human body can exist in both worlds at the same time. As long as the emblem is charged, Lu Wu can travel between two worlds at a time, and at the same time, he can carry the maximum weight of material that a single person can bear. The limit of a normal person is about fifty kilograms, and considering the effect of the magic ring, Lu Wu can carry at least five times more weight.

Of course, there are some things that you can't carry. For example, it's dangerous to bring the Resonance Stone directly. Because according to the master, there is a certain difference between the rules of the two worlds after all, and the earth should not allow such a thing as a resonance stone to exist at all. Therefore, once it is brought over, it may be directly annihilated, quietly and completely disappear - this is still a relatively good result - and it is even worse that it may directly become an explosion, or even an antimatter explosion, which is more dangerous than an atomic bomb. It would be difficult for even the most powerful warlock to survive with such power, let alone ordinary people.

However, if you are carrying precious metals, you should be perfectly fine.

Most countries strictly control the import and export of precious metals, and the sea, land and air are completely blocked and strictly guarded. However, it is never possible to monitor everything within your own country.

If nothing else, Lu Wu knew that there was a gold shop on the street (if nothing else, there was one near his residence) and a pawnshop that had a business of recycling gold. If a store collects dozens or hundreds of grams of gold a day, that is, 350,000 yuan of funds, it will not attract anyone's attention at all. In fact, according to Lu Wu's estimate, for a city like W City, with a population of nearly 10 million, not to mention tens or hundreds of kilograms of gold, even a few tons, it can be quietly digested. At least a few tens of millions are not a problem.

Of course, gold is not actually the most expensive of the precious metals. Precious metals are not only ornaments and preserved assets, but also indispensable industrial raw materials. Precious metal catalysts (e.g. platinum) are indispensable in many industrial processes. Not to mention many special alloys, which themselves need rare metals as raw materials. For the metallurgical industry, it is not uncommon to buy a batch of raw materials with tens of billions of dollars in stock.

He came to the window again, and suddenly he felt as if he fit perfectly into the word "ambitious." It is estimated that even people of Ren Jian's type do not plan to change the whole world by their own strength.

And most importantly, there are no dangerous moonmen here. So he can achieve his goals slowly, in the safest and most appropriate way. Lu Wu didn't believe that there was such a First Legalist of the Dark Moon Fang who came to Earth so coincidentally.

The night in the distance became thicker, and a neon light flickered, rendering a pillar of hope in the night sky.

The game hall is brightly lit. At this time, the lights were on, it was still early, and it was full of people. However, the game consoles such as racing cars, motorcycles and dance machines are not patronized, and on the contrary, most of the game consoles such as fishing, zombie fighting, birds and animals, and forest dance parties are full. This is enough to show the inclination of the guests here.

A large circle of people around a fishing machine – a common occurrence in such establishments, usually means that a special lucky person has appeared. Although there were many people, they were all standing and watching. There was the crackling of keys in the crowd and, of course, the occasional gasp of people.

This time, sitting in front of the fishing machine was a young woman.

"Damn, that's okay?" someone shouted. The reason for this cry was that the woman had caught a big fish. This fish directly won back all the money she had paid before, and there was a slight surplus.

This woman has such a fast hand!

However, the woman seemed to get tired of it, and she eventually pulled up the magnetic card and left the position. Instead, he sat down on the other side of the "Forest Dance".

"Who is this woman? she looks pretty good!" someone whispered.

"It should be Liu Fatzi's junior!" someone also replied quietly.
