This sea voyage did not take much time, probably because Wei Xu's ship was modified to have an electric engine and was much faster, so it reached the northern continent in just five years.

When he came to the Northern Continent, Wei Shu only felt that the Northern Continent was unfamiliar, and the wooden houses, fences, and fields he had built at the beginning had all disappeared.

I planted the tree man seed, but now I don't see the tree man.

Perhaps the Treants were completely wiped out in the catastrophe, or perhaps they were resurrected, but they migrated elsewhere, and nothing is known.

The weather is indeed warmer, the snow is gone, the plants are growing vigorously, the animals are more, and from time to time there will be some rare-level creatures, this rare-level creatures usually occupy the mountain as the king and dominate the party, but they are unlucky to meet Wei Shu.

Because Wei Shu needs to collect magic stones.

After Wei Shu got off the ship, he went all the way north, the closer he got to home, the better his mood became, but because the northern continent had been changed beyond recognition, in fact, he didn't know which was where, so in the process of going north, he was also looking for some places that were famous before stopping.

For example: Mount Emei!

Wei was looking for fifteen years before he finally found Mount Emei, the mountain is still the same mountain, but he can no longer see the word Emei.

First of all, there were the crowds of tourists, for more than two hundred years, they still stood still like statues, the years did not leave a trace on them, they were protected by golden light, nothing could hurt them, not even let them move for half a minute.

Wei Shu found the Inheritance Cave, he didn't go in, but left a mark at the entrance of the cave.

He'll come back, but only after he finds his hometown.

With Mount Emei as a reference, it took Wei Yu three years to find the original toll station.

There were no monkeys left in the toll booth, and after that terrifying strong cooling, the entire northern continent was cleaned, and the monkeys who had the opportunity to develop their own civilization were also cleaned.

Seeing all this, Wei Shu didn't know whether he should be happy or sad, at least, the monkey group that might pose a threat to the humans who had stopped recovering from time had disappeared.

With this toll booth as a signpost, Wei Wei began to move in the direction of his hometown, the highway had disappeared, and countless vehicles were trapped in the jungle.

But these vehicles are like road signs, they clearly indicate the location of the original high-speed kilometer and the direction of the road, Wei Shu followed this "high-speed kilometer", only three days to find his hometown.

Looking at his hometown, looking at this city surrounded by jungles, Wei Shu was full of emotion, he came to the community where he lived, and found the community building where he once lived, but unfortunately, he couldn't get in.

The door of the residential building was protected by golden light, no matter how much strength Wei Shu used, he could not break it, and the windows were blocked by the anti-theft window guardrail, and Wei Wei could not enter at all.

But Wei Xu only needs to wait for more than 60 years, and he has waited for more than 200 years, does he still care about these more than 60 years?

Wei Shu began to use his ingenuity to build a shelter, Wei Shu did not have a ready-made blueprint for the shelter, but he had blueprints such as generators and water purifiers, and the camp where Lu Qiqi was located gave him inspiration, and he could build a shelter after that camp.

Moreover, Wei Shu can do research, he can first use the blueprint to build a generator, and then dismantle it, study its internal structure, study and study, even if he doesn't use the blueprint, he can build it himself.

Wei Shu's practice and exercise continued, but on this basis, Wei Shu began to study science and technology again.

Compared with other creatures in nature, human beings are most powerful in their minds and wisdom, and today, Wei Shu is going to show his wisdom that belongs to human beings!

Moments later...

"Why is this generator so complicated?"

Like most people, Wei Shu dismantled the generator and couldn't install it.

Wei Shu immediately comforted himself: "It's okay, I'm not that kind of machine genius, as long as I study for another three months." ”

Three months later...

"Why is this generator so complicated?"

After three months of research, Wei Shu still couldn't install the generator, and he could buy materials and learning materials through the mall, these materials were not too expensive, but it was a little difficult to teach himself, but Wei Shu couldn't reinstall a dismantled generator after studying for three months.

Wei Shu: "..."

It seems that I don't have that kind of talent.

The knowledge in books is very boring, not something that ordinary people can learn, and it is only a theory, just like we can't make atomic bombs and TNT explosives after studying high school physics and high school chemistry, people who don't have this talent and interest really can't study the manufacture of electrical appliances only through textbooks.

But as long as you learn, understand, and build a knowledge system and framework in your head, then making and inventing will become a simple thing, and even as long as there are enough materials, it is not difficult to build a spaceship.

This is the most precious thing left to mankind, after all, the current human intelligence is really overwhelming other creatures.

If you get out the star-destroying ships, neutron battle stars, black hole builders and the like in the market, then don't say anything epic, even if it is a legend, a mythical level is estimated to be able to fight against it.

With Wei Shu's current strength, he can completely survive without pressure, but with his level of knowledge, he can only make toys such as paper airplanes and paper windmills, but he still has more than sixty years to go, and he is really not in a hurry at all.

More than sixty years have been able to do a lot of things, Wei Xu began to build a shelter, this shelter is based on the city, after all, the time is over, the buildings protected by the golden light can still be used, he only needs to make some electric motors, solar engines, cables, wires and so on.

Other than that, it's research, after all, there are so few blueprints in the infrastructure that you have to build scanners to scan for lost technologies or other people's made ones.

Of course, you can also do your own research, research these technologies by yourself, and re-light the human science and technology tree.

Now Wei Shu is doing this thing, he thinks that he can generate electricity as a basis, and then manufactures all kinds of electrical equipment, first uses blueprints to build, and then dismantles them for research, and after studying clearly, he understands the principle of electrical appliances, as for parts and materials, they can be purchased from the mall, or dismantled in the blueprint electrical appliances that have been manufactured.

This is how Wei Shu intends to study and practice at the same time, but in doing so, the time of the day is obviously not enough, 24 hours a day is too short!

Wei Shu felt that he had to change his thinking, his current life expectancy was more than ten times that of before, and as long as he replenished his food and water source once, he could go months without eating or drinking, and he could also go without sleeping for months, so why did he still use it day by day like before?
