Inside the secret room.

A flash of light.

Xu Yi's soul returned to the physical body.

Opening his eyes, he regained control of his physical body.

"Once the soul leaves the body, the body will be completely incapacitated, and this state is not very good!"

Although his physical body is very powerful, ordinary missiles may not be able to hurt him, and even due to the fact that the physical body is broken and the true yuan is broken, his body has an almost immortal activity.

Theoretically, it is impossible to be like Tie Guan Li, the Yuan Shen goes out for a walk, and when he comes back, his body is gone.

But in this defenseless and slaughtered state, no one knows what kind of accidents will occur.

Xu Yike didn't want to lose his body for no reason.

Although with his current soul body, even if he lost his physical body, he could turn into pure soul cultivation, he still felt that it was better to cultivate both life and life.

"If only I could put away my body in the soul state!"

"Of course, the best state is that I can achieve the perfect integration of spirit and spirit, and I can realize that even in the physical state, I can perfectly borrow the power of the soul!"

In these two ways, the former may involve the use of spatial capabilities, and the latter may involve the integration of higher realms.

"Space Power ······"

Xu Yi looked at the void in front of him, thinking in his heart.

Perhaps, he can try to comprehend the power of space in this world.

Under normal circumstances, with his current realm, he would not be able to reach the level of comprehension spatial ability, but who made this world so easy for people to 'shatter the void'?

"It is difficult to comprehend the power of space in a short period of broken void, and we must find a way to 'slightly' extend the time of shattering the void."

"However, this practice also has drawbacks, if you are not careful, it is likely that it will really make me directly shatter the void!"

Although Xu Yi was still only in the second realm of martial arts, his strength had already exceeded the upper limit of this world, and if it weren't for the mysterious beads that had been suppressing him, he would have been forced to shatter the void and go.

Now, if he takes the initiative to break the void and doesn't stabilize it, it's really hard to say what the outcome will be.

"I have to find a way to slowly test out the 'degree' of this, and while maintaining the power that allows me to comprehend space, it will not let me really shatter the void and leave."

Xu Yi's eyes flickered, and he was quite interested in this matter.

This may be the easiest time for him to comprehend the power of space!

In other worlds, he may not be able to have such a good environment.

"But for now, let's put this matter aside for now, and upgrade the memory palace first!"

Xu Yi calmed his thoughts and let himself be as empty as possible to achieve a better state.

Although it doesn't matter if he does it or not, once he turns on the state of earnestness, he will go straight into the state of perfection.

But doing and not doing are two completely different concepts.

In fact, Xu Yi has been trying to automatically enter various special states without the help of mysterious beads.

At that time, he himself is his own plug-in!

And with various special states as a reference, he has not done nothing in the past hundred years.

If one sets his primitive state as one, his earnest state as twelve, and the middle state as ordinary.

So now, he can stably open four times the normal state, or even six times the normal state, and he can occasionally turn it on.

This is the ordinary state he has entered without borrowing the mysterious beads!

"One day, even if it is a state of seriousness or even a state of epiphany, I will be able to open it stably with my own strength!"

Xu Yi firmly believed this in his heart.

That is, of course, someday in the future.

Now······

"Get serious!"

"Build a Level 10 Memory Palace!"

Xu Yi borrowed the power of the mysterious bead and opened the state of earnestness again.

At this moment, he turned on his serious state again, and the effect he could achieve was far beyond the imagination of ordinary people.

If the cultivation state of ordinary people is one, then Xu Yi's cultivation state at the moment is at least a thousand, or even thousands!

Thousands of times the cultivation ability of ordinary people, how terrifying this is, there is no need to describe it too much at all.

The tenth-level memory palace, which was originally extremely difficult to build, also began to become rapid under such conditions.

Starting from the martial arts tree, I saw only the top leaves, and they began to become 'real' at a speed that was visible to the naked eye.

Level 10 memory palace, this is already involved in the construction of cells and molecules, and normal people can't see anything wrong with it if they don't go through microscopes and other instruments.

Even for the vast majority of Grandmaster-level martial artists, it was impossible for them to see how these leaves were different from the real ones - both were the same in molecular structure, so why did you say that these leaves were fake?

This is also one of the difficulties of the tenth-level memory palace.

First of all, the first requirement is that you need to have the means to be able to observe the molecular level.

This is not a means that you can do with all kinds of scientific instruments, but a means that you can have!

Can a scientific instrument help you observe the cellular and molecular structure of the leaves in the outside world, but can it help you observe the cellular and molecular structure of the sea of your soul?

Because of this, it is destined that the tenth-level memory palace is not something that ordinary people can build at all.

Even ordinary grandmaster-level martial artists may not be able to build it—like the grandmaster-level martial artists of the previous world, they can't do this.

Although they can borrow the power of True Yuan to greatly strengthen their eyesight and allow them to see the microscopic world, they are not yet able to reach the cellular molecular level.

The grandmaster-level martial artists of this world, if they hadn't cultivated their souls and strengthened their spiritual power, they would also not be able to observe the cellular and molecular level.

And that's just the first step, observation.

The later build is even more difficult!

That's at the cellular and molecular level!

How many molecules are there on a leaf alone? Hundreds of thousands, even millions!

What about a branch? What about a tree?

That's all in the hundreds of millions!

If you expand this range to the entire small courtyard, it is a number in trillions.

And you need to build them all one by one, without a single mistake, and you have to make them completely solid.

This kind of project is tantamount to allowing ancient civilizations to directly consider the issue of ascending to the sky.

This is also Xu Yi, which can open a special state and greatly strengthen his own ability.

Anyone else, even a god-man in the Immortal Realm, may not be able to do such a thing. Or even if it could be done, it would take tens of millions of years.

Knowing the sea.

With the blessing of his serious state, Xu Yi quickly upgraded his memory palace.

One leaf, two leaves, three leaves······

The leaves, which are constructed from the cellular and molecular level, become more 'real' existences, and then use the 'real' to store illusory memories.

Just like a small USB flash drive, which can store tens or hundreds of gigabytes of information, after these blades become 'real', the storage capacity has skyrocketed!

According to conservative estimates, this storage volume has skyrocketed by at least 100 times compared to before!

It is hard to imagine how many memories and information he will be able to store once Xu Yi completes the upgrade of the entire memory palace.

When he was in the ninth-level memory palace, he had stored almost an entire knowledge of modern civilization, which had not yet been filled.

If you increase it by a hundredfold on this basis······

Don't dare to think! Don't dare to think!

······

A day later.

"It's too slow!"

Xu Yi couldn't help frowning as he looked at the small piece of branch on the top of the tree that had turned into a 'real' tree.

Building such a small area in one day is already very fast compared to his previous time.

At this rate, it would probably only take him three or four months to turn the entire martial arts tree into a 'real' existence.

If you're lucky, you should be able to complete the upgrade of the entire Memory Palace within ten years, upgrading it from a Level 9 Memory Palace to a Level 10 Memory Palace.

Ten years, in exchange for a tenth-level memory palace, this transaction is completely worth doing!

If it was Xu Yi before, he might have some ideas about this time, but he would probably still be willing to do so.

It's just that today's Xu Yi is a little dissatisfied with this efficiency.

"I can't stay in this world for long, according to the original plan, there are probably only about ninety years left."

"In this time, if I still want to comprehend the power of space, then I must reduce the time in other aspects as much as possible!"

The power of space is not an ability to comprehend.

Even if this world is relatively special, if Xu Yi wants to comprehend it, he will inevitably need to spend a lot of time to invest in it.

And the time he spent in this world was limited after all, if he spent ten years on the memory palace, then there was even less time left for him to comprehend the power of space!

"Let's try it first, in the state of epiphany, can we greatly shorten this time!"

Xu Yi extracted some 'immature' spiritual seeds.

"Turn on the state of epiphany!"

"Build a Level 10 Memory Palace!"

As Xu Yi's current best auxiliary cultivation state, the increase in the epiphany state for him was obvious.

Knowing the sea.

The martial arts tree in the middle of the memory palace is moving into 'reality' at an extremely exaggerated speed.

After a simple test and calculation.

Xu Yi came to the conclusion that if he could be provided with sufficient psychic power, then he was sure that he would be able to complete the construction of a level 10 memory palace within a year!

And this sufficient spiritual power, after quantification, is about equivalent to 5 to 70,000 years.

"Seventy thousand years?"

Xu Yi frowned.

Now he can only obtain more than 10,000 years of psychic power in a year.

Seventy thousand years of spiritual power, it would take him almost five years to assemble.

In fact, five years is already a very fast time, but thinking that this time can be increased to one year at the earliest, Xu Yi felt that he needed to make a choice.

"Let's optimize the Dao Heart Demon Cultivation Dafa first!"

This was what he had set before.

It's just that at that time, he felt that compared to optimizing the Dao Heart Demon Cultivation Dafa, it was a higher priority to upgrade the memory palace, so he went to upgrade the memory palace first.

I didn't expect to go around and around, but now that I'm back to optimizing the "Dao Heart Demon Cultivation Dafa", I'm back to it.

"After the previous few optimizations, on the Dao Heart Demon Cultivation Dafa, I have basically optimized everything that can be optimized, and then I want to carry out in-depth optimization, and even greatly improve the efficiency of obtaining spiritual power, but it is not so easy."

This is also one of the reasons why Xu Yi chose to upgrade the memory palace first.

After the first few optimizations, he could almost be said to have exhausted the martial arts knowledge he had accumulated.

If he wanted to make significant optimizations and improvements, he would have to accumulate a lot of martial arts knowledge again.

Now that he has not acquired a lot of new martial arts knowledge, it is theoretically difficult to continue to optimize the Dao Heart Demon Cultivation Dafa.

Even if it is an optimization, it is only a small optimization and does not play a big role.

"But maybe."

Xu Yi thought of his soul and soul limit.

The possibility of the Dao Heart Demon Cultivation Dafa and the power of the soul is greatly related to the power of his own soul and the power of the soul.

"My short test before didn't test all the changes after the soul limit and the soul limit were broken, what if there happened to be a change in this that could greatly enhance the demon seed?"

This kind of thinking has the meaning of luck, but at this time, Xu Yi can only rely on 'luck'.

Fortunately, his luck was not bad.

It really made him discover a method that could greatly increase the power of the soul - after the soul limit and the soul limit were broken, Xu Yi's own soul power and soul power were only about doubled.

But I don't know if it's because of the sublimation of the essence, so that Xu Yi has a large capacity to withstand the number of split demon seeds.

Xu Yi only improved the method slightly, and the number of demon seeds increased by nearly ten times!

This promotion also turned Xu Yi's harvest of more than 10,000 spiritual powers per year into nearly 100,000 years of spiritual power in one fell swoop.

At this moment, it not only solved the problem of the memory palace that had been plaguing Xu Yi, but also greatly improved the harvest of his spiritual power.

"It's a big step away from me being able to use the power of the mind at will!"

Xu Yi was extremely satisfied.

That's an annual income of 100,000 years of spiritual power!

Haruka remembers that in the last world, all the spiritual power he gained was added up, and it was less than a thousand years, right?

At this moment, his annual income is more than 100 times the income of the previous life!

All I can say is ······ Soul Break and Soul Break YYDS!

Spiritual gas, every breaking limit is a transformation of Xu Yi's essence, and many changes will not even be discovered by himself if he does not experiment himself.

"If you have time in the future, you still have to study these four limits more!"

Xu Yi thought in his heart.

But for now, the most important thing for him is to solve the matter of the memory palace first, and other things can be put aside first.

With the blessing of sufficient psychic power, the problem of upgrading the memory palace is naturally no longer a problem.

A year later.

"Level 10 Memory Palace, build complete!"
