In fact......

For a strong person like Qing Yu in the Tribulation Period, whether there is a higher level of cultivation after the Tribulation Period, Qing Yu and the others still know.

God-level ......

The powerful level of the power of the owner to create the world and destroy the world is just that on the earth, there is far from such a rich spiritual power to allow the strong who have reached the tribulation period to break through that bottleneck.

According to what that person said, the former human beings actually gave up the path of cultivating the truth because they found that the spiritual power on the earth was not enough for anyone living on this planet to break through to the legendary miracle, and instead turned to devote themselves to another path called mechanical technology.

For these more complex cases, that one also classifies them in detail.

As for the scientific and technological path taken by the previous human beings, the one who called it mechanical technology, and the various magical and powerful items made by all human beings, that one is also explained after a long time of exploration and research.

A series of tools and weapons made by pre-humans were assembled using a variety of small and large mechanical parts.

It's not uncommon for these things to be assembled from mechanical parts.

For example, the current battle golem is a very obvious product of mechanical technology.

It's just that the previous human beings studied mechanical technology in an extremely in-depth manner, but the current immortal cultivators only know a little bit about mechanical technology.

According to ancient records, as well as various field trips.

That one also discovered that in order to better study their mechanical technology construction, the previous humans actually formulated a set of laws and formulas to assist them in better manufacturing various tools.

As for the path that the immortal cultivators are walking now, that one is planning it to be biotechnology.

To put it simply, for mechanical technology, it is just to create a variety of products that are spliced together from scattered mechanical parts.

As for biotechnology, it is to strengthen its own strength through various methods to achieve the effect of continuous evolution.

It seems that pre-humans have also studied biotechnology, such as the medicines brought back by Mu Chen and others, which are the embodiment of pre-human research on biotechnology.

However, these elixirs do not seem to have the same effect as those of the various panaceas of the present.

Generally speaking, it means that the research of biotechnology by the former human beings and the current immortal cultivators are not in the same direction.

Whether it was discovered that the spiritual power on the earth was not enough to make people break through to the god level, or whether they had not found the right development path of biotechnology at all, which led to the previous human beings choosing to study mechanical technology, that one did not dare to make a rash decision.

It's just that people who lived on this planet in two periods chose different directions of development.

If you look at this planet alone, it is actually an extremely sensible way to choose to develop biotechnology, because it seems that the development of mechanical technology will produce something called 'chemical reaction'.

The various wastes released by these 'chemical reactions' can greatly harm the ecological environment on the earth, which is also the previous human beings who made the previous earth full of trauma, so that they finally embarked on the road of abandoning this planet and flying to the universe to find a new home.

Of course, this does not mean that these technologies are useless.

For imagining the development of space, for the vacuum area in space, it is difficult for people who choose to develop biotechnology to carry out various activities in space before they break through to the god level.

It can even be said that if an immortal cultivator who has not broken through to the divine technique, if he is exposed to the space environment, then he may not survive for a second, and he will die directly.

For the former human beings who chose the path of mechanical technology, even if the physique of all human beings was completely inferior to the immortal cultivators who chose the path of biotechnology development, they were able to create all kinds of tools to make themselves constantly fight against the natural environment.

For example, the previous human beings only developed on the earth for nearly 10,000 years, and they were able to rush out of the earth and travel in space to find their new home.

However, the current immortal cultivators, since no one has ever been able to break through to the god level, even if they have been developing and evolving on this planet for tens of thousands of years, no one can go to space for long-term activities.

And now, for the invasion of extraterrestrial civilizations in the near future, that one is calling on the immortal cultivators on this planet to speed up the development of mechanical technology research and breakthroughs.

Otherwise, everyone has no ability to fly into space at all, so for the invasion of extraterrestrial civilizations, if they want to meet them, they can only fight against them when they enter the atmosphere on the earth.

However, if those extraterrestrial civilizations are really allowed to enter the atmosphere at that time, then it is not certain who will still have the initiative.

In fact, for the research of mechanical technology, as early as thousands of years ago, the predecessors of the human race discovered the power of mechanical technology, but because the development of mechanical technology will greatly pollute the ecological environment on the earth, so the development of mechanical technology research of the human race is progressing very slowly.

However, even so, for mechanical technology products such as puppets, they are still the first to be manufactured and used by the Terrans.

I have to admit that mechanical technology is powerful, because ......

For the human race, which had a bad relationship with the demon race, the beast race and the demon race before, in the face of the oppression of these three races, in addition to the stubborn resistance of the strong people of the human race, he still has a lot of combat exploits.

That is, after the Terrans took the lead in using puppet battles, the other three races discovered and realized the power of mechanical technology products, and they also chose the development path of biotechnology as the mainstay, supplemented by mechanical technology, rather than pursuing the development of biotechnology as a single one like before.

In this way, the development path of biotechnology development and mechanical technology development has also continued until now.

And now for the research of mechanical technology, in fact, everyone is not very thorough, except for the puppet first invented by the human race, which can now be regarded as entering the period of the Great Perfection, the research of other mechanical science and technology products is still on the surface, and there is not much progress.

In recent hundreds of years, the only major breakthrough in mechanical science and technology products.

That's the jetpack that the Terran one invented.

This jetpack is not ordinary, this tool that uses charcoal as a raw material can convert the heat energy emitted by charcoal into kinetic energy for downward eruption.

And it is because of this downward eruption kinetic energy that people who have recently been able to equip this fountain-colored backpack can also fly into the sky without using spiritual power.

It is this jet backpack that is equivalent to replacing the flying or mount of the sword in disguise, and it is because of the emergence of these mechanical technology products that the current immortal cultivators realize the power of the previous humans.

Moreover, for the former humans, they were looking for the current immortal cultivators to appear and survive on this planet for millions of years.

If the pre-human race had not become extinct, then the extent to which the mechanical technology of all mankind had developed may not be known to everyone.

It's impossible to know.

But......

After these millions of years of development, it is tens of thousands of times stronger than the current immortal cultivators.

And now the powerhouses of the four races are worried about the extraterrestrial civilization that is constantly approaching the earth and has obvious signs of invasion, and everyone can clearly find that that civilization is also taking the path of developing mechanical technology.

And according to the observations of the past few years, that extraterrestrial civilization can easily destroy the asteroids that stand in their way.

This shows that the technology of that extraterrestrial civilization has surpassed the level of technological development when the previous humans left the earth.

But......

The current powerhouses are also not sure, if the current immortal cultivators are fighting against the mechanical technology products of the former human beings when they just left the earth, who can be better?

And now, the extraterrestrial civilization that wants to invade this earth has developed to the point where mechanical technology far exceeds that of the pre-human beings when they left the earth in front of them.

Moreover, what the powerhouses on the earth can observe now is only the product of the development of their mechanical technology, and the current powerhouses don't know anything about the extent to which the biotechnology of that extraterrestrial civilization has developed.

If that extraterrestrial civilization was not only so advanced in mechanical technology, but also comparable in biotechnology to them, then if the immortal cultivators on the earth wanted to win, it could almost be said that there was no possibility of winning at all.

Therefore, if you want to protect this planet, if you directly fight with it, for immortal cultivators who do not have god-level powerhouses, it is undoubtedly to touch stones with eggs.

But......

Can we just watch the earth being invaded by the alien invasion of extraterrestrial civilizations?

The answer is definitely no.

Then what kind of methods do the immortal cultivators on the earth have to resist that extraterrestrial civilization?

In addition to speeding up the development of mechanical technology, the powerhouses have also opened a mysterious passage to the earth's core.

Our only purpose for opening such a passage is to find an opportunity to directly detonate the earth's core when the earth is really completely defeated by extraterrestrial civilizations, and we will not hand over our homeland for generations to an alien invading nation!

And now, for the appearance of this Void Lord bloodline Mu Chen, who has the creator of the world, it is undoubtedly an extremely powerful hope for everyone!

So, in fact, after that four-clan competition, the powerhouses of the four clans signed an agreement-

Cultivate Muchen to the god level at all costs!
