It was called the Demon Realm in ancient times, and now it is commonly known as the World of Parallel Worlds, and it is currently quite dangerous.

It's not that the level of civilization development in the parallel world is particularly high, the main thing is that that world is now full of radiation, and if you forcibly integrate that world, you have to integrate all that radiation into the current world.

The end of the world first occurred because of the strong radiation.

It has caused an existential crisis for mankind.

Isn't that a danger?

Less than two hundred years after the end of the Immortal and Demon War more than 10,000 years ago, a great war broke off within them in the parallel world, and the specific reason is no longer known.

Anyway, a devastating war was fought.

After the end of the war, the original high-level civilization of the Demon Realm was basically destroyed, and the civilization directly entered a reset state.

It is that after the destruction of the previous civilization, the remnants of human beings have entered a kind of apocalyptic survival due to the great regression of scientific and technological civilization, and the overall civilization level is still regressing, and finally regressing to a relatively primitive level.

The state of the approximate tribal era is called Civilization Reset.

It is equivalent to the young hero in the game, please start again.

One of the cores of the development of civilization lies in the population, without a sufficient population, it will not be able to give birth to a complete and complete scientific and technological system, and there is no way to support the existence of a complete scientific and technological system, and without a complete scientific and technological system, it is difficult to continuously improve the overall scientific and technological level and civilization level.

It can even go backwards.

After the Battle of Yashan at the end of the Song Dynasty, tens of thousands of remnants of the Southern Song Dynasty fled to the desert island to survive, but in just a hundred years, they degraded from the highest level of civilization in the world to a level that was only no better than some local natives.

The first is that the technology they carry is incomplete, and the second is that the small population cannot support the entire scientific and technological system.

High-precision technology is not achieved overnight, each high-precision technology has already transformed all the mid-end technology and basic industries into intelligent operations, after the end of the war, this series of systems basically collapsed, many proficient in high-precision technology, in the absence of the corresponding basic system of reliance and equipment, in fact, there is no use.

Then there was a technological disconnect.

It is normal for the level of civilization to continue to degenerate.

What's more amazing is that that parallel world has preserved the cultivation techniques that were snatched from them quite well, and later, when their descendants gradually adapted to radiation, they derived a weird radiation cultivation system that absorbs all kinds of radiation energy to cultivate.

But either way, that parallel world is tricky.

A world full of radiation.

Definitely a horror poison.

The life in that parallel world, after so many years, may have already adapted to the radiation environment, and even derived the corresponding cultivation system, and now the civilization has re-evolved to the feudal society, but the world where Ding Yun is now is not adapted to radiation.

The two worlds need to really come together.

I'm afraid that a group of people will have to die first.

A group of dead people in the number of billions.

So the best choice is actually to ignore it, anyway, as long as you don't care about it, it will take thousands or even tens of thousands of years for these two worlds to completely merge.

What does this have to do with her then?

She didn't know where else she was going.

To put it mildly, it is probably a problem that these individuals, these countries and civilizations in this world will not be there after thousands of years.

Maybe they're all extinct.

So there's really no need to worry too much.

After thinking about this, Ding Yun gave up killing two birds with one stone, and by the way, he planned to engrave that parallel world with his own brand, but out of consideration that the original body was still thinking about her fiancé, so Ding Yun decided that before leaving, he had to help them fulfill their wishes and reunite the two of them.

And the main difficulty of this matter is:

In the end

Pick up Heo Jun from the parallel world.

Or send the soul of the original body over.

If Xu Jun wants to come back, send the original soul over, although they are reunited, but it is undoubtedly not a perfect reunion, and the original body has to be separated from her parents, if he doesn't want to come back, take him back, in case he tries to go back and so on.

No, it's also a hassle.

Therefore, Ding Yun could only reluctantly act as a transit point, and with the authority of the world, he jointly contacted the original body in the Shattered Secret Realm Relic, and Xu Jun, who had begun to adapt to radiation in the parallel world.

Pretending to be the headquarters of the Public Security Department.

Tell them where they are now, and ask them what they think, saying that there is only one chance, think about it, and have no regrets to take.

The original body didn't want to leave his parents, and at the same time, he also hoped that Xu Jun could choose to come back, after all, the country and the people were safe, and his parents were there, so it was better than the parallel world that had just developed into a feudal society and was full of radiation.

But if Xu Jun doesn't want to.

She can also think about it again.

Xu Jun was also busy and directly said that he wanted to come back, and asked if he could bring back a junior brother who was still surviving, not long after they entered the parallel world, the mentor died because of radiation, and the remaining senior brothers, sisters, and brothers, some of them couldn't stand the mutation of radiation and committed suicide, some died due to radiation, and some magically adapted to radiation, but did not adapt to feudal society.

Eventually, he died from various causes.

Only he and his junior brother Niu Xiao were relatively poor, and he specially dug a deep pit to hide in the same place, and relied on the materials brought back by his senior brothers and sisters, and rarely went out of the hole.

That's what I've been doing until now.

Although some of them were malnourished, at least they were not wanted, they were robbed and killed, and they often hid in caves, so they were exposed to relatively little radiation.

They barely survived in good health.

There is no conflict between the ideas of the two sides, which is also a good thing for Ding Yun, and it saves her from doing ideological work, but just when Ding Yun is about to take Xu Jun back.

He made another request, saying if he could bring back the bodies of his mentor and his brothers and sisters.

so that they may return to their homeland and settle in peace.

Anyway, one is a belt, and two are also belts, plus even if Xu Jun's mentor and senior brother and sister die, they also have the imprint of not belonging to that parallel world.

It's not that hard to find.

So Ding Yun didn't refuse, and simply used his world authority directly to find and bring them back together, and at the same time put them back in place.

That is, the no-man's-land of Qu County where they disappeared.

After doing this, Ding Yun contacted the Public Security Bureau again, told them about the situation, and reminded them to quickly send someone to deal with the radiation on Xu Jun's body, and then she withdrew her soul from it.

While dragging the soul of the original body out of that small secret realm, stuffing it back into her body, she chose to return.
