Yu Sihui's death made Chu Tianyu blame himself very much, but what is the use of blaming himself when people are dead? Chu Tianyu still has to continue to walk with the people who follow him, and live well in this world, the only thing Chu Tianyu can do for Yu Sihui now is to hope for the existence of heaven, where she will always be happy and happy, where she can reunite with her parents and brother, and live happily forever in that paradise without pain and without killing.

The relocation work of Ci'an City lasted for almost a month, but there were too many people and corresponding equipment and materials that needed to be relocated in Ci'an City, and the population alone reached more than 600,000 people, not including the people with extraordinary abilities, and the relocation work was even more cumbersome with the materials and technologies accumulated by UM Company for decades.

But fortunately, Chu Tianyu has Bi Qingming, a business wizard, otherwise just busy carrying these things can make Chu Tianyu crazy, in the past, Bi Qingming had the opportunity to live a life of eating and waiting for death in the base, there was no way that the base was too small, it was not enough for Bi Qingming to display his talent, and now Chu Tianyu suddenly asked him to be responsible for transporting hundreds of thousands of people, as well as a large number of materials and equipment, and instantly resurrected Bi Qingming, and became the business wizard who strategized again, with the help of Jiang Sichen and others, Bi Qingming arranged the relocation work in an orderly manner.

But even if Bi Qingming was in the relocation work, it took almost a month, it was really Chu Tianyu's base was too small, and it would definitely not be able to accommodate so many people, materials and equipment to be placed suddenly, so the base had to be expanded, but fortunately, Chu Tianyu's base was not short of food and electricity, and now there were more than 600,000 people, so many laborers were there, and the expansion of the base was progressing rapidly.

Chu Tianyu didn't want to build his base like Ci'an City, and make a towering wall of life, it didn't make sense at all, the so-called wall of life was as brittle as paper when encountering a powerful opponent, so Chu Tianyu just asked Bi Qingming to expand the residential area in the base, as well as the area where materials were stored, it was not difficult to build these, it was originally a small base under the work of hundreds of thousands of people, and it didn't take long to become a large survivor base, but the entrance to the base was too simple, but it didn't matter, as long as Chu Tianyu was given some time, sooner or later this base would have the appearance of a large survivor base。

It is worth mentioning that Chu Tianyu has made a fortune this time, not only has he gained more than 600,000 people, but also obtained all the technologies and corresponding materials accumulated by UM over the years, and there are corresponding scientific research personnel. The scientific researchers are here, and Chu Tianyu's base is not short of electricity, so Chu Tianyu can continue to climb science and technology, but at present, the main climbing technology is weapons, after all, Chu Tianyu's strength is still weak, even if Duo Lin, the princess of the giant clan with a battle value of more than six million, is here, but there are still extremely powerful gods and dragons in this world, and there may be an existence among the zombies that far exceeds Su Yin's strength, and finally those monsters with huge bodies.

For these guys, just having one Doreen is not enough, and the strength of the human ability is too weak, just relying on the human ability and Chu Tianyu and the viper army under his control, there is no way to resist these existences.

Therefore, Chu Tianyu hopes to use the powerful technology of UM Company to see if he can develop more powerful weapons, once these weapons are there, Chu Tianyu can not worry about the safety of his base, and he can rest assured to find the holy elf to heal Lei's injury.

Therefore, the next development goal of the base is weapons, but Chu Tianyu will also divide some scientific researchers to continue to develop some problems in medicine, after all, Chu Tianyu can't always stay in the last days, he still needs to return to his own world, and in that world Chu Tianyu needs these medical technologies.

Now that there are so many scientific researchers, and many of them are engaged in medical research, the progress of Chu Tianyu's work to explain Edward's detoxification of cancer cells has been greatly accelerated, and Chu Tianyu does not want to eat a fat man in one go, and immediately wants to crack the secret of cancer cells, so that human beings can completely get rid of the threat of cancer, and even find a way to live forever, he just hopes that Professor Edward and others can find a way to make the special enzyme in cancer cells ensure stability for ten years.

In fact, before the end of the world, the pharmaceutical department of UM Company was doing this scientific research, and now Chu Tianyu asked them to continue this project, and provided enough manpower and material resources, so as to speed up the research and development progress of this topic, and in a while the scientific research team can find a way to make the enzyme in cancer cells stable for ten years.

With this medical team with strong scientific research capabilities, Chu Tianyu will let them continue to develop various medical technologies in the future, and then bring them to the world where he is located to build Chu Tianyu's own medical empire, but this is all for later.

Now what Chu Tianyu has to do is to integrate and create his own base.

Now Chu Tianyu finally has his own troops, he has subdued all the surviper troops, among which there are even masters like No. 88, but it is a pity that when Chu Tianyu infiltrated the fortress, he used the Sky Splitting Sword to make No. 1 lose his mind, this guy almost slaughtered the top 100 people in the battle value of the Viper Force, so that the strength of the Viper Force left for Chu Tianyu was greatly reduced, and there was only one No. 88 left with a combat value of more than one million, and the others were all more than 600,000 abilities.

There are more than 1,200 surviper troops surviving, which seems to be a small number, and there is only one No. 88 with a combat value of more than one million, which is definitely not enough to see the existence of Shangsu Yin, but if it is an attack on other survivor bases, there is almost no base in the world that can resist the attack of this force.

There is no way that human beings will become very weak in the last days, even if the strongest person in the human race now has a combat value of only more than 600,000, which is similar to the guard of an ordinary viper force, and in the face of an army attack with a minimum combat value of more than 600,000, the survivor base created by the human race can resist it? It is estimated that there is no, but it is also possible that the base will have such strength, but there is no such base around the location of Chu Tianyu's base at present.

Chu Tianyu didn't like the name of the Viper Force, and after the reorganization was completed, he directly changed the name of this unit to Dawn, which means the dawn of mankind, this unit was handed over to No. 88 to lead, but it was Ren Xuelei, these soldiers could not improve their strength by devouring other races, they could only improve their strength through combat like other abilities, which made the combat effectiveness of this unit not improve rapidly.

But this is not a problem for Chu Tianyu, don't forget that Chu Tianyu has an ability similar to Ren Xuelei, it can't be said to be ability, it should be said to be a skill, collect skills, as long as Chu Tianyu leads this unit to kill more demon beasts and collect the essence of the demon beast's body, it can make this unit quickly improve its strength, but if you do this, it will make too much noise, so that the strength of more than a thousand people will increase rapidly, how many demon beasts will have to be killed?

Once this method is known to Su Yin and the others, it is estimated that they will not be able to sit still, and they will definitely find ways to kill Chu Tianyu, it is really Chu Tianyu's existence that affects their safety.

Now that the base is still under construction, Chu Tianyu naturally doesn't want to find this trouble, so he has no idea of improving the strength of the troops for the time being, but he asked Andri, Jiang Sichen, Wu Yuanwei, corpse, Gege, Qilia and others to form a team to go out to hunt demon beasts, Chu Tianyu has to let their combat value increase as soon as possible, and let them be the backbone of the base.

The result is that the demon beasts within a radius of 100 miles with the base as the center are unlucky, except for those extremely powerful demon beasts Chu Tianyu did not make a move, some other demon beasts with similar strength to Andre were constantly slaughtered, and then Chu Tianyu used the collection skills to help them collect the essence of the demon beasts' bodies, so that they could improve their strength as soon as possible.

When Andre and his people's combat value reached more than 600,000, Chu Tianyu was afraid that his actions against the surrounding demon beasts would attract the attention of Su Yin and others, so he directly returned to country A with Andre and others, and continued to slaughter demon beasts far away from Su Yin and these guys to help Andre and others improve their strength.

Three full months later, when the combat value of Andri's people increased to more than one million, Chu Tianyu finally stopped this journey of fighting monsters and leveling, first of all, there were no suitable demon beasts around for them to kill, and secondly, there was news from the base that the medical research team had developed a drug that could stabilize the enzyme in cancer cells for ten years according to Chu Tianyu's requirements.

With this medicine, Chu Tianyu has to return to the time and space where he is, he can't always stay in the last days, and the old man Cai Jianhong's illness can't be dragged down, and the old man will have to swallow his breath if he drags it down.

After Chu Tianyu led Andre and the others back to the base, he returned to his world with the drugs and corresponding equipment developed by the medical R&D team.

Chu Tianyu's departure was actually more than four months away, but this was in the last days, and almost half a month had just passed in the time and space where he was, but even after half a month, Cai Jianhong's had already reached the point where the oil ran out, and if Chu Tianyu was delayed for a few days, the old man would definitely die.

When Zuo Chunrong heard Chu Tianyu say that he had cracked a certain genetic sequence of cancer cells and developed a method that could make the strange enzyme in cancer cells stable in the human body for ten years, Zuo Chunrong was like a cat that had been stepped on by its tail, and he jumped three feet high, seeing Chu Tianyu stunned, the old man in front of him was a handful of age, and it was really rare for him to jump so high at such an age.
