"Are these two children twins?"

Su Xiaofan looked at the pair of children in his arms, and with a thought, a burst of energy entered the bodies of the two children.

The child lying in Su Xiaofan's arms felt warm and comfortable, and fell asleep after a few breaths.

"They are twins, they are five and a half years old this year."

Su Mu saw the child sleeping and asked, "Dad, what did you do?"

These two children shopped like crazy every day, and they were so energetic that they never slept.

"Let them take care of themselves and they'll be fine."

Su Xiaofan waved his hand, looking at the daughter in front of him who had grown up and became a mother, he felt very emotional in his heart.

One of his apprentices and a pair of children practice his own planetary skills, and the foundation was laid by Su Xiaofan himself.

Now Zheng Hao's cultivation level is almost equivalent to that of a Nascent Soul cultivator. He is still far away from breaking through to planetary level life. His daughter's body only has a cultivation level equivalent to the Golden Core stage.

Of course, Su Xiaofan's Nascent Soul and Golden Elixir here correspond to earth cultivators. The energy level within the seal is too low. Their current cultivation level is just an illusion in Su Xiaofan's view.

"This is still not suitable for cultivation."

Su Xiaofan shook his head. After integrating with this inexplicable world, although the energy level on the earth has improved slightly, it is still far inferior to that of a normal planet.

The seal cast by Da Neng is extremely powerful. If Su Xiaofan hadn't practiced ancient cultivation techniques, he might have been suppressed by the seal after entering the earth.

The higher your cultivation level, the more you can feel the terror of the earth's seal. For example, the cultivators on the earth now think that the boss of heaven is the second best, but they don't know that they are just frogs in the well.

"Okay, let's talk about what happened in the past few years, and where have your grandparents and others gone..."

When Su Xiaofan came back this time, he felt like the world had changed a lot. The earth had changed so much that he almost didn't recognize it at all.

"Dad, in the second year after you left, the earth merged with another world..."

Su Mu sighed and told what happened on earth in the past twenty years.

The speed at which the earth merges with another world far exceeds the estimates of relevant departments and Su Xiaofan.

So much so that in the initial stage of integration, all countries on Earth were not prepared, and after creatures from another world entered the Earth, they caused great damage.

On the earth at that time, although the spiritual energy was revived and there were more and more cultivators, their strength was much weaker than that of the creatures in the fused world.

If modern weapons were not still usable, I am afraid that the sudden fusion would have caused even greater casualties to humans on Earth.

Not all the fused worlds are filled with creatures that are malicious to humans.

The human beings that Su Xiaofan saw in his mind, wrapped in animal skins and looked like savages, actually shared the same hatred as the people on earth and jointly resisted the invasion of wild beasts.

Coupled with the continuous support of high-level cultivators from all over the country, China gradually stabilized the momentum. However, in the first three years, many high-level cultivators were killed or injured.

Among the people Su Xiaofan knew, Senior Brother Kong and Fang Yijun of the Jianzong died in the battle, Uncle Liu'an of the relevant department died in the battle, Han Zhongli of the Eight Immortals Sect died in the battle, and Tieguai Xian lost a leg. He was really inseparable from Tieguai.

But it was the three years of hard work that allowed humans to recover and drive the wild beasts that emerged after the fusion back into the mountains and rivers.

"Uncle Liu'an died in the battle?"

Hearing the news, Su Xiaofan felt a pain in his heart. The old man who had always loved and cared for him could not help but appear in front of his eyes. He never thought of saying goodbye and never seeing him again.

Moreover, Han Zhongli's heroic appearance also appeared in Su Xiaofan's memory. When he was in the Glacier Restricted Area, that man was also very protective of himself.

"Yes, Master Liu'an died in the mouth of a two-winged tiger in order to help humans evacuate."

Su Mu knew that his father had a deep relationship with Lu'an, so he told the story of Lu'an's death in the battle.

"Go on, how was this giant city built?"

Su Xiaofan waved his hand, suppressed his thoughts about Lu'an, and signaled his daughter to continue.

Su Xiaofan was very curious about this giant city. There are thousands of such giant cities on the entire earth, and there are more than thirty in total in China.

Although the earth's technology at that time was not bad, Su Xiaofan felt that it was not enough to build such a giant city, and judging from the traces on the city wall, the giant city must have existed for more than twenty years.

"Dad, most of this city wall has already been built, and we have been maintaining it for the past twenty years."

Su Mu's words were somewhat beyond Su Xiaofan's expectation. This huge city wall was actually the fusion of that world.

Under his daughter's explanation, Su Xiaofan gradually understood what had happened on the earth in the past twenty years.

Because the world merged too suddenly, at the beginning of the integration, the entire earth's terrain changed drastically.

Many people who originally lived in the countryside found themselves in the wilderness when they woke up, surrounded by trees hundreds of meters high, and the surrounding environment was extremely harsh.

Although the relevant departments responded in a timely manner and immediately sent out troops and cultivators to help those people come out, the deep mountains and rivers were the home of wild and ferocious beasts.

In order to rescue the trapped people, the army suffered the most serious casualties. With the cooperation of the cultivators, only less than one-fifth of the population was evacuated.

This is only in China. Among other countries, some small countries were even directly wiped out. The number of people on the entire earth suddenly dropped from the initial six billion to only more than one billion.

However, very few of the people who can stay are old, weak, sick or disabled. They are either scientific researchers or cultivators who are strictly protected by the state. Most of these people have gathered in the giant city.

As for this giant city, it appeared in various places after the world merged, but when it was in that world, the giant city seemed to have been attacked by many, and the city walls were in dilapidated condition.

In the past twenty years, humans have not stopped repairing the city wall, and it has reached its current scale, which can withstand the invasion of the ferocious beasts of the ancient times.

As for technological development, it has almost completely stagnated in the past two decades.

For unknown reasons, the earth can no longer connect to satellites in outer space orbit, and mobile phones are no longer usable.

Therefore, the current method of contact on earth has changed to the kind of telephone with a pull-string that was used decades ago.

However, due to the dangerous environment outside the giant city, it is impossible to pull telephone lines between the two giant cities, so even this kind of phone can only be used within the giant city.

However, the electricity on earth can still be used, but modern firearms are not powerful enough against the ferocious beasts outside the city. On the contrary, cold weapons are extremely powerful.

For example, giant crossbows made with high technology are even more powerful than anti-aircraft guns. They will show powerful lethality every time a beast wave occurs.

As for the beast tide, it is the king of beasts in the deep mountains and rivers, driving vicious beasts to attack the city, which happens almost every five or six years.

As for airplanes, they can no longer be used. First of all, the terrain of the earth has changed drastically, making it impossible to extract oil as before.

Secondly, there are many flying ferocious birds, and the sky is no longer the territory of humans. Once the aircraft takes off, it will be chased and attacked by those ferocious birds.

Also because of the fuel, the spacecraft was unable to take off. After Su Xiaofan left, the earth has not sent a satellite into outer space.

Fortunately, more than twenty years have passed, and humans have gradually stabilized their position, and many weapons against ferocious beasts have been developed.

Moreover, humans have not given up on scientific research, and more and more technological products are produced using electricity and spiritual stones as driving energy.

For example, the cars running in the giant city now are basically trams, and most of the spirit stones are used in some technological weapons.

Today's spiritual stones are no longer as barren as the earth was before.

After the integration of this world, people discovered many spiritual stone mines. In order to compete for the spiritual stone mines, countless battles broke out between humans and ferocious beasts.

Basically, the spirit stone mines close to the giant city are occupied by humans, while those deep in the mountains and rivers are the territory of ferocious beasts, and humans cannot get involved.

Generally speaking, the integration of the earth and another world will basically bring disasters.

The enemies are ferocious beasts in the wild rivers. They are countless in number and vary in strength from strong to weak.

The stronger ferocious beasts are comparable to human Nascent Soul cultivators, but their combat power far exceeds that of humans.

Basically, within a thousand miles, there will be a beast king comparable to the Nascent Soul, commanding all the beasts on its territory.

Weak ferocious beasts are basically not comparable to ordinary people. As long as they can be called ferocious beasts, at worst they are similar to human Qi-training practitioners.

The most important thing is that there are too many ferocious beasts, and the wilderness has given them the opportunity to thrive. After killing one batch, another batch pops up, almost inexhaustible.

However, the energy contained in the bodies of these ferocious beasts is several times stronger than the extraordinary restricted areas on earth. Eating them will be of great benefit to cultivators.

Therefore, killing ferocious beasts and eating meat over the years has also given rise to a large number of cultivators.

Almost everyone on earth today is a cultivator.

The merger of the two worlds, regardless of the technology, is an indisputable fact that the earth has become a cultivator civilization.

Legend has it that in the depths of the wild river, there are even more terrifying beasts that can command the beast king.

However, no one has ever seen such a ferocious beast. Occasionally, the roar of ferocious beasts can be heard from the depths of the wilderness, which makes Nascent Soul cultivators feel a little frightened when they hear it.

In the world that was merged, there were also human beings, the barbarians that Su Xiaofan saw in his mind.

The number of barbarians is not very large. It was extremely difficult for them to survive in the past, and their living space was almost occupied by ferocious beasts.

After the fusion, there were only over 30 million barbarian tribes on the entire earth.

But the strength of these barbarians is very strong.

Even ordinary barbarians are born with the strength of Qi-training practitioners, and when they reach adulthood, they are extremely powerful and can tear apart tigers and leopards.

These barbarians do not know how to practice qi, but they can directly use the spiritual energy of heaven and earth to temper their bodies. The strongest barbarians among them can fight against the beast king alone without falling behind.

After merging with the earth, due to language barriers and different habits, the barbarians initially fought with humans.

But soon both sides realized that if they continued to fight, they would be even more unable to deal with the increasingly powerful beasts.

As a result, humans quickly reconciled with the barbarians, and the two sides strengthened exchanges and cooperation.

In order to ward off the ferocious beasts, humans even passed on their cultivation techniques to the barbarians.

But those adult barbarians cannot practice human skills. Only newborn barbarian babies can practice the skills.

These babies showed great strength when they were young, and now many barbarians who have practiced the skills have become strong men in the barbarian community.
