A month later, the python's house was built, all made of wood, and Wang Tian took some of his people to make several steam engines during this month.

If there is not enough manpower, he can only replace it with machinery, this time Wang Tian does not plan to keep it anymore, and hand over all the things he knows to the clansmen to develop industry.

To create more powerful weapons, if it weren't for Wang Tian's ignorance of making nuclear weapons, Wang Tiandu planned to make some nuclear weapons at this time, and with nuclear weapons, he would definitely be able to destroy the Tyrant Empire.

"Master, you should leave." Wang Tian was just about to rest, when a voice came from his head, and then the sealed memory was also unsealed.

"Did something happen?" Wang Tian asked suspiciously.

"The will of this universe is about to take shape, and when the time comes, your existence will definitely be discovered, and outsiders will definitely be killed." Xiao Ling explained.

"Will the universe be destroyed? Then why didn't our cosmic will kill the demons when they invaded our universe before? After listening to Xiao Ling's answer, Wang Tian was even more puzzled.

"The demon invasion is not one or two, this is also a test for the creatures of this universe, plus the will of the universe where they are located, this universe has no time to take care of it.

The nascent cosmic origin has not been destroyed or consumed much, and the will of other universes is stronger than that of other universes, and it is difficult to invade on a large scale. Xiao Ling explained again.

"In other words, there are not many powerhouses in this universe now, and the battle between the human race and the fierce beast has not yet yielded results, right?" Wang Tian asked again.

"The top powerhouse has already divided the winner and loser, and now this universe is ruled by fierce beasts, and most of the resource-rich places are occupied by fierce beasts, just like the master's current place is just a barren land, and there is no genius treasure."

"Maybe I should do something before I leave." Wang Tian plans to leave behind some exercises, as well as the techniques of alchemy refiners...

"Master, the laws of each universe are different, the exercises cultivated in the universe where we are located are not suitable here, the formation of the will of this universe will descend to the supreme exercises, so master, you don't need to leave the exercises.

But technology is not in the list, you can leave information about technology, but it must be recorded in the text of this world, and the words you taught before can't, they will be erased. ”

Xiao Ling's words made Wang Tian break off this thought, and then Wang Tian immediately went to the old people in the tribe and the women who had traded before, and asked them to use the written records of this universe to explain to them day and night.

It took a month to record the scientific knowledge on the earth, and I originally wanted to record the technology of the world where Doraemon was located, but there was not enough time.

"Patriarch, are you leaving?" Wang Shu saw that Wang Tian had not rested for a month, and guessed that he should be leaving, but in fact, not only Wang Shu, but even other clansmen also saw it. Just let Wang Shu be the representative to ask Wang Tian.

"I don't want to leave, but I don't belong here. You can use this knowledge to help you become stronger. Wang Tian patted Wang Shu's shoulder and said.

"Patriarch, we ...... without your leadership"

"You can do the same without me, many people in the clan are better than me, if it is possible, I will come back, I hope that the Wang tribe will still exist by then, and I can still meet a few familiar people." Wang Tian didn't let Wang Shu continue.

"Rest assured, Patriarch, we will not let you down."

As soon as Wang Shu's words were finished, Wang Tian disappeared...

……………………………………………………………………………

Returning to the earth again, after hundreds of years of development, the earth has changed greatly, the aura has begun to recover, and the countries on the earth have formed an alliance, mainly in China.

Although there are many martial artists and cultivators, they are not as chaotic as the cultivation realm, and the alliance countries control most of the resources, and there are many strong people cultivated.

The development of science and technology has changed dramatically compared to when it left, the semi-intelligent optical brain has been studied, and the aerial spacecraft has achieved space jumping, flying out of the earth to find a new planet of life.

There were still very few humans on that new planet of life, and it belonged to the era of beast hegemony, and the Federation sent millions of troops to occupy it, and from there it was constantly transporting resources back.

The land has also expanded several times, this is some seaweed plants brought back by Lu Ma from the Xiuzhen Realm, which grow wildly on the surface of the sea, can bear millions of tons, and is harder than the land.

"You're doing a good job, it's time for the moon to be developed, let Doraemon send a few star cores over, install them on the moon, and plant some plants."

The moon just lacks a star core, with which people can live on it, which can generate gravity and rejuvenate life.

"Yes, shopkeeper." Dover and Luma said at the same time.

"Go ahead..."

Wang Tian arranged for them to enter the store after leaving, and found that the goods in the store had increased a lot, and the number of customers in the store had also increased, but many goods were out of stock.

"Xiao Ling, recruit another batch of alchemists and refiners, let them refine in their own plane, and then give a certain amount of compensation..."

"Master, the development of the Unicom plane is good now, but it is not necessarily a good thing to continue like this. As there are more and more powerhouses in those planes, even ordinary people can cultivate even if they have the right exercises, the population is also growing exponentially, many planes are unified, and there are few wars. But there are only so many resources, and as the population grows, so do the resources needed.

In addition, we have plundered some of it, and in the long run, the resources of those planes will be depleted, and even if the cultivation realm has the river water of the immortal realm to nourish those elixirs, it will take a certain amount of time to grow, and it will not be able to keep up with the consumption. ”

Wang Tian listened to Xiao Ling's words and fell into deep thought, in the past, there were still most people in the cultivation realm who could not cultivate, or their cultivation qualifications were poor, and the competition for resources was already very fierce.

A large number of cultivators died every moment, and now that the mortality rate has been greatly reduced after unification, those customers who have their backs to the store are powerful and terrifying, and Wang Tian has made them follow the laws of the earth, and the possibility of rebellion has been greatly reduced.

The war is because of the lack of resources and ambitions, and now it has not broken out, but the resources have not yet been lacking to a certain extent, and once it breaks out, it is absolutely unprecedented.

"So what do we do now? We can't let them go back to what they used to be! Wang Tian asked Xiao Ling.

"Actually, it's not like there's no way to solve ......"
