Sitting in his own cave world, Zhang Qing thought cross-legged.

He was carefully studying the various exercises in the world of cultivating immortals, trying to extract something from them.

Don't look at the power of the Supreme Immortal Court is so powerful, but the things in the Immortal Cultivation World are not completely useless.

Just to say one thing, the Mahayana period in the human realm of the immortal cultivation world has a lifespan of more than 10,000 years.

This is equivalent to the advanced professions of the Supreme Immortal Court, and the lifespan of these advanced professions of the Supreme Immortal Court is only a few hundred years at most.

And when it comes to the immortal realm of the world of cultivating immortals, it is said that an ordinary immortal has a lifespan of 100,000 memories!

And Zhang Qing has reached the current tribulation realm, and his strength is comparable to that of some immortals of the Supreme Immortal Court, and he can't even reach ten thousand years old.

There is so much difference between the two, it can be seen that the foundation of health preservation and life continuation in the world of cultivating immortals is really extraordinary.

If the lifespan of the Immortal Cultivation World can be added to the exercises of the Supreme Immortal Court, then how much change can it bring?

Zhang Qing was really curious.

So after studying carefully for a long time, he reluctantly chose to give up.

Because he is not the material to do this at all, although the names between the two are quite similar, they are completely different systems after all, and they are extremely conflicting with each other.

"If it really doesn't work, why don't you just take out the exercises of the immortal cultivation world and give them to your parents to cultivate?"

Zhang Qing thought about it, after all, although he gave them gods on the earth, where can they be immortals at ease, and it is naturally excellent to be able to live for a while longer.

But before he could make a decision, he suddenly felt a feeling in his heart.

That was the warning given to him by the Heavenly Dao of the Supreme Immortal Court, not allowing the exercises of this immortal cultivation world to be disseminated.

Zhang Qing immediately understood, this was because these exercises were profound in the essence of the world of cultivating immortals, and cultivating these exercises was tantamount to deviating from the Heavenly Dao of the Supreme Immortal Court.

At this moment, it was the time for the Supreme Immortal Court to digest the world of cultivating immortals, and it was even more strictly forbidden to spread it.

In the future, the Immortal Cultivation World has become a member of the Supreme Immortal Court system, and after these exercises are transformed, they will probably be able to appear in front of people in a grand manner.

After understanding this, Zhang Qing let out a long sigh, and could only completely lock these exercises in his memory.

However, he was a little curious, he had indeed brought back the talent of manipulating steel from the Iron Universe before, how could he not be warned when using it?

Or is it okay to use it yourself, but not to spread it?

Does this give the prospector a special kind of power?

Zhang Qing suddenly laughed, if that's the case, it's still a very good thing.

Some regrets that he couldn't pass on the immortal cultivation method to others, and Zhang Qing could only walk out of the cave world.

Although he has now entered the tribulation situation, he is not in a hurry to overcome the tribulation.

Just after entering the realm of calamity, everything in the world will gradually generate corresponding calamities according to itself.

Then these calamities will appear in the corresponding time, so it is impossible to do things like crossing the tribulation in advance.

Zhang Qing's catastrophe still has a long time to come, and when it is about to come, he will have a sense, and when the time comes, the sky will be confused, that is, to find a suitable place to break the catastrophe.

For example, run to another world and go to the catastrophe.

Of course, this is a good thing to do, but to be clear, calamity does not change depending on the circumstances.

Running to a world of the lowest level, the upper limit strength is only 10 physical attributes, but the catastrophe encountered may encounter the terrifying monsters that survive in the void, and some world-devouring existences are directly swallowed together with the world, and it will be too late to regret it.

Therefore, it is also important to pick the right things, and it is better not to involve external conditions, and it is better to just be the intensity of the current world.

These are the lessons of blood and tears of many ancestors of Huoyun Palace, and since Zhang Qing has seen these, he naturally will not make so many bad mistakes.

"The beginning of the three tribulations, generally speaking, begins with the human tribulation."

Zhang Qing thought of this and didn't care too much.

The difficulty of the human robbery is not in other places, but in its own strength.

The human calamity is only aimed at itself, and some enemies may be lured into attacking themselves in the human calamity.

Kill them, and you'll basically survive the catastrophe.

Then there is the Earth Tribulation, which is the most difficult level among the three Tribulations.

But don't worry too much about this for the time being, Zhang Qing still has a long way to go before he even robs people.

As for the final tribulation, it is the easiest to get through, as long as you have enough merit, you can use the merit to protect yourself and lie down directly through this level.

Zhang Qing doesn't have much else, but he grabs a lot of merits, and he can be said to be the most stress-free one for the Heavenly Tribulation.

Leaving all the affairs of Chongtian Peak to the elders, Zhang Qing turned around and returned to Earth.

He has been back for so long, and he has not visited the earth properly, and after so many years, he still has some expectations for what the development of the earth has become.

Because before leaving, he had ordered Yu Shanqiu to let her supervise the research and development of science and technology on the earth.

But after all, the times are different, although there are still many scientists, but more of them are studying martial arts and how to further strengthen themselves.

Therefore, in the past two hundred years, the development of science and technology on the earth has not developed as rapidly as Zhang Qing thought.

But for Zhang Qing, what he saw should be so-so.

The moon has been developed by humans, and a number of lunar cities have been established on it, and after undergoing technological transformation, the moon has fully adapted to human life.

Moonman has gradually become a proper noun.

Another colony of the Earth is Mars.

The development of Mars is difficult and has only been carried out in recent decades.

There are hundreds of bases on it, and a huge ecological circulation system has been built, isolating tens of millions of square meters of land from the outside world, and slowly transforming the atmosphere.

But if you want to completely change Mars, it will take at least a hundred years to do so.

Since even Mars can be logged in in batches, the technology tree of interstellar aviation is naturally very good.

Although it is not yet possible to move away from the solar system, there is still no problem with the deployment of space near the Earth.

However, the development of life technology for people on the earth is somewhat unsatisfactory, and compared with the previous two hundred years, it has not improved much.

At least it didn't reach the level where Zhang Qing was stunned by those scientific and technological products after he came back.

In addition to the development of science and technology, the most commendable thing on the earth is probably that someone has finally surpassed 5000 combat power.

It has reached the level of the pinnacle of martial arts that people once imagined - Martial Saint!

Nowadays, there are not many powerhouses who have entered the Martial Saint level, only nine of them.

These people are also known as the Nine Saints, and their strength is earth-shattering, and in some nether realms, one person can destroy a realm, which is called the walking doomsday disaster.
