Where will it be placed? With Su Yu's personality, if he really had something to give to himself three hundred years later, what would he think? Shu Han searched in Su Yu's room for a long time, but found nothing, couldn't help but be a little discouraged, sat on the bed with only wooden planks left, and couldn't help but bow his head and ponder.

"First of all, this place should not be easy to be discovered, and secondly, this place should not be easy to forget for yourself, otherwise if it is too easy to find, then it may be snatched away by people who have strayed into it, and if it is a place that you don't even know, it is impossible to find it at all.

He once told Su Yu that the end of the world is very dangerous, and he should know that he can't come out for a particularly long time, so he will definitely put it in a place where he has a deep memory, to ensure that he can find things at the fastest speed, where is such a place? Shu Han couldn't help but think of a place, he walked out of Su Yu's room, went straight to the room that once belonged to him, opened the door, the dust inside was blown out by the wind, Shu Han blocked his mouth and nose with his hand and immediately walked into his former room, directly into the toilet.

After looking around, he walked to the toilet, opened the lid on it, and looked at the contents inside, Shu Han couldn't help but show a special smile, only to see a closed box being placed in the toilet to store water, sure enough, Su Yu was similar to his own brain circuit, Shu Han took out this box from the toilet that had no water, and there were many cockroaches in it, obviously the survivor of Dati's release of insect repellent before, looking at the closed box in front of him, Shu Han couldn't help but sigh Su Yu's intimacy.

Three hundred years, the oxidation of the air is enough to make many things impossible to save to the time when they can see, so this box is made of a completely confined space, and it may not have been fully in contact with oxygen for three hundred years, holding the box in his hand, Shu Han only felt that the box was unexpectedly heavy, put him on the table next to him, and saw a four-digit password on it, Shu Han casually entered his birthday, and opened the box without accident.

I saw that there was a book made of steel inside, obviously, in order to let these materials be passed on to future generations, Su Yu did not hesitate to use a lot of money to engrave these materials on the steel, under the protection of the airtight box, these materials were only seen by Shu Han, in addition, there is also a desert eagle, I don't know how Su Yu got this gun, it is estimated that after the end of the world, it was obtained from some places.

Su Yu opened the book, and the glimmer of the torch was lit, and he couldn't wait to see that judging from the contents of the box, the content of this book was obviously left behind after Su Yu entered the apocalypse, so there must be many records about the apocalypse, so for Shu Han, this is undoubtedly crucial, maybe it can solve the biggest confusion in his heart.

"Shuhan, if you can read this book, I'm afraid it will be three hundred years later, and now at this moment, the collapse of human civilization, as you said, is happening, it was just a global electrical signal not working properly, but then everything returned to normal, just when we thought it was just an ordinary solar storm, the earth is changing rapidly in ways that humans don't know.

In just a few months, news of animal attacks on humans began to frequently make headlines, plants began to grow wildly, and some people with special abilities began to create their own religions, preaching that the earth was about to be destroyed, and only by believing in them could we obtain eternal life.

Later, terrible diseases enveloped the entire earth, and by the time I write this letter, more than 7 out of 10 people in the world have died from the disease, and there is no doubt that human civilization has entered a dangerous situation, and just a month ago, according to news reports, in the Mediterranean region, an unprecedented volcano erupted, and now, our sky is also shrouded in volcanic ash, according to scientists, I am afraid that in the next twenty years, human beings will not be able to see the sun, and plants will die in a large area.

We were forced to move underground, and now I am about to leave for the underground with my family, accompanied by Tan Yongming's family and your family, as for you, I'm sorry, I didn't know where you were at the time of writing this letter? After you told me to leave a letter to you in the future, you disappeared into our news network, maybe you found something and are going to do something.

I hope this letter is helpful to you, that book made of steel, it is you three hundred years ago, explain your affairs, please read it carefully, I believe that it is very important to you, as for that gun, I don't know if this gun can be used three hundred years later, I hope he can help you.

In addition to this, in the basement of the villa, I have stored a large number of drawings on architecture, biology, chemistry, physics, and military technology, which I think will help you to increase your prestige, my old friend, I may have died by the time you receive this letter, but please do not forget that I will always stand with you wherever you are.

Su Yu.

November 7, 2022"

After reading this letter, Shu Han's eyes were already full of tears, Su Yu, his brother in this life, actually didn't have any sensational words in the letter, but it still made Shu Han unable to help himself, but Shu Han also knew that he couldn't reveal too much in the private relationship between men and women at this moment, he had to restrain himself and deal with these things as soon as possible.

Living in such an environment as the end of the world for a long time, Shu Han's control of emotions is no longer comparable to that of the high school student he once had, he quickly cleaned up his mood, and then carefully put Su Yu's letter in his personal position, and then turned out the steel book, compared with the steel letter left by Su Yu, this book is lighter, and there are fewer words on it, the reason why it is called a book is completely because he uses too much steel, so this book is very heavy.

There are few words on it, but the content is very important, Shu Han looked very seriously, only to see that it was written: "Another me, I haven't seen you for a long time, I don't know how you will live in three hundred years, I have been thinking, now I am you now, so will my memory be synchronized to your brain?"

Before the end of the world, I often wonder what is the relationship between us, one soul and two bodies? Or are two different souls softened in one memory? It's boring, but I do like, if that's the case, then I'm afraid I don't need to write this letter to you, obviously maybe we're the former.

The earth has changed completely, animals are becoming more and more powerful, while human beings have to retreat underground under the pressure of nature, and a large number of people have died in disasters, and the earth seems to have chosen to abandon his most beloved child in an instant, which is undoubtedly a tragedy for mankind.

But thankfully, in this tragedy, your family, and mine, survived, because I, you, have awakened to become Skywalker, and our family has been given the protection they deserve, and that's why you can't return now, Skywalker is in some way different from normal humans, their muscle makeup, and even their genetic sequences have changed significantly.

I think that's why you can't go back to the modern age, our bodies are different, so even if the soul fits, it can't be reintegrated into the body, if you want to go back to the modern age, awaken your talent, and become a Skywalker, maybe the only way, of course, there may be other ways, but I don't know right now.

Okay, that's all for the private conversation, now I'm going to say something very important, three hundred years later, you, human civilization is gradually reviving, and at this time, we, human beings are begging God for forgiveness, but all this, there is no clue, we only see the surface now, but how specifically, no one can know, why the earth's environment has changed suddenly, so far scientists have not given a definite answer.

And why I crossed over, there is no one to answer, Shu Han, I need you to bring a response to the present me from the future, that may be the key to solving the puzzle, try to become a Skywalker, only in this way, we can find the answer to the puzzle. ”

Xia Shuhan's letter ended here, from beginning to end, his words and titles were very strange, calling Shuhan you at once, calling us at once, as if he was struggling with whether he was himself or not? This made Shu Han feel a little weird atmosphere, but at the same time, Shu Han's request made him feel extremely shocked, becoming a Skywalker? Is this the only way to be able to return to modern times?

Is it that easy to be a Skywalker? He couldn't help but continue to flip back, only to see that after Shu Han's letter, it was the possible reason for becoming a Skywalker, the first kind of change in his own temperature caused a mutation in his body, and awakened in the process, this is a guess that Shu Han once made, and now it seems that it should have been confirmed in Shu Han's era.

The second is that a strong body can awaken the ability, of course, the premise is that the body itself must have the talent gene of the ability, from now on, this path is obviously more suitable for himself, this body looks skinny, but since the previous life can awaken the ability, and the two bodies are connected by a soul, then at least the two bodies should be similar to a certain extent.

The third point is the violent mood swings, many Skywalkers are greatly stimulated by emotions, and finally mutate and become Skywalkers, in addition, there is also a way, which is to use animals in nature as a guide, so as to make themselves break through.

According to Shu Han's description, the animals in nature today seem to be a little bit of ancient times, the legendary giant beasts are general, with extraordinary energy, and some of these particularly fierce giant beasts will form a core inside the body, so as to make themselves have a stronger ability, Shu Han understands it as an inner pill, similar to the golden pill in the cultivation of immortals, as long as humans swallow it, it can promote the transformation of body functions, so as to have the ability of a part of the giant beast.

It's just that this kind of murderer's inner pill has a very brutal factor, so after most people swallow this kind of inner pill, they will be affected by these violent factors, so they will gradually lose their minds and begin to move towards madness, so Shu Han reminded Shu Han in the letter that if it is not a last resort, do not try to use the last method, which will force people into a desperate situation, and even become a killing machine completely, a humanoid beast. “

This kind of thinking Shu Han really hasn't experienced, he also feels that this world is becoming more and more mysterious, what fierce beasts, and Skywalker, really makes Shu Han have an unheard of feeling, but at least after reading this past self to the current self, after writing the guidelines, Shu Han's heart is finally no longer as confused and scared as before, he knows how to return to the modern era, and also knows how to become a Skywalker, which will be the biggest gain of this trip for him.

He put the steel book back into the sealed box, and then solemnly put him back into the reservoir of the toilet, the book is too heavy, if you bring it back, I am afraid it will attract the attention of others, it is better to put it here, since I have been here once, then I want to come again in the future, it is more familiar.

And Shu Han estimated that the next time he came back, he would probably already be a Skywalker, and at that time, it would be relatively convenient to get to this place, as for Su Yu's letter and the desert eagle, Shu Han naturally took it away, and took the king of this pistol in his hand, just feeling completely different from those ordinary pistols, his revolver was in front of him, like an old man who was in the middle of his life, and Shu Han also knew something about this gun.

The Desert Eagle, compared to an ordinary pistol, weighs two kilograms alone, compared to its peers, it is undoubtedly the best, in addition, the recoil is amazing, only eighty kilograms can control him to avoid being overwhelmed, like Shu Han's physique, I am afraid that if I shoot a shot, I don't know if the enemy is dead or not, I am afraid that I will have to be recoiled by this gun, and I will turn a person on his back.

But this is what excites Shu Han, such a gun, in modern times, may not be nothing, in the era of cannons, airplanes, tanks, such a gun is just a good thing in the eyes of collectors, but in this era, this gun can definitely bring a lot of help to Shu Han.

Its initial speed can reach 400 meters per second, and the initial speed of his revolver is only about 200 meters per second, and the decline in speed is very fast, and the accuracy is also very poor, the desert eagle can accurately shoot at the enemy two hundred meters away, in this era, it is comparable to a sniper rifle, and more importantly, this gun is really very handsome, the all-black design, plus the expansion of nine bullets, makes this gun like a work of art, and I don't know when Su Yu bought this gun, How much money was spent.

When human civilization dies
