During this time, Tang Yi has been working hard to comprehend his own Yuanshen, but it is too difficult to find such a thing as Yuanshen from his body. Pen ~ Fun ~ Pavilion www.biquge.info Moreover, Tang Yi's body is extremely strong, and the situation in the dantian is very different from that of ordinary cultivators. It is more difficult to comprehend the original spirit.

Now, he happens to have a large amount of experience points left, and since it is difficult to improve by relying on his own cultivation, he might as well try the self-service upgrade system to upgrade it.

Take the best spiritual weapon flying sword back into the dantian, and cultivate it with your own mind.

In this way, you can reach the level of integration of man and machine as soon as possible, so as to exert more powerful attack power.

After taking care of the weapon, Tang Yi put all his thoughts on cultivation.

Open the self-service upgrade system.

"Tang Yi: Realm: Out of the Mortal Period, can be upgraded, the next level to open a cave sky, you need experience points of 30,000!"

After the de-mortal period, the self-service upgrade system gives the next level of realm, which is not Jindan, nor is it comprehended Yuanshen.

Instead, open a hole in the sky!

"Dongtian?"

"What is this?"

He summed up the cultivation methods of the various major sects, and he had never heard of such a realm.

Between heaven and earth, the cultivation method of Qingyunmen is the most comprehensive.

Tai Chi Xuanqing Dao is in Tang Yi's hands, and it has even been upgraded to the Three-Rank Purple Lotus Exercise. However, Dongtian, this realm, made him look dazed.

"Why don't you try it, see what kind of realm this Cave Heaven realm is?"

"The self-service upgrade system, so far, there has been no error, and the information judged has always been accurate."

"System, upgrade my realm for me!"

After Tang Yi's mind gave the order, the self-service upgrade system automatically began to upgrade.

In Tang Yi's dantian, earth-shaking changes suddenly took place. The twelve regiments of true elements seemed to be boiling. One of them turned into a whirlpool, and a crystal was produced in it, which seemed to be the precursor to the condensation of Jindan. In the center of the whirlpool, lightning flashed, and there was a loud sound.

Suddenly!

Boom, it exploded!

At this moment, Tang Yi's whole body shook violently, and his consciousness descended into his body and entered that whirlpool.

With this explosion, Tang Yi saw a shocking scene.

In the viscous immortal yuan, the crystals that had just gathered exploded in an instant, and light appeared in the dark world. Divide yin and yang, set the world, in which the clear floats, the turbid sinks, here, it has become a small space, space appears, the concept of time exists, time and space appear, from then on, self-contained.

Click~

Tang Yi, who was in a state of surprise, was attracted by the huge momentum and looked up.

Only 100 meters high in the sky, there is a big hole, the sky, broken!

"How did it appear?"

What smashed this small space out of a big hole was the singularity in Tang Yi's dantian, and after the singularity came to this world, it bloomed with countless dense gases, making this small space gradually full of life force.

The air is getting stronger and stronger!

It seems, it has reached another extreme!

The singularity shook, and a purple light rushed out of the singularity, and as soon as this purple light came out, the small space suddenly did not move, and all the restless chaos was suppressed!

"Hongmeng Immortal Aura!"

This light, Tang Yi is very familiar with, at the beginning, it was with the appearance of this light that he was able to condense the singularity, support the cultivation all the way, and even integrate the singularity and the exercises, and cultivate into half of the insight into the starry sky.

After this strange divine light appeared, it rose to the sky in this small space, like a supreme spiritual bridge, reaching the sky and the earth.

After walking around, the space was completely stabilized. Hongmeng Immortal Aura returned to Tang Yi's singularity again, and when it returned, the singularity also underwent some changes, and it was slightly larger.

Everything has settled, the singularity has disappeared, and he has returned to Tang Yi's dantian.

Tang Yi walked around in this small space, the ground was very thin, only three meters thick, and the sky was not enough, but it was only a hundred meters.

However, it is indeed a separate time and space.

Here, it's a world that belongs to him alone!

Here he is God!

As soon as the mind moved, the singularity reappeared.

Tang Yi released the power of the Immortal Yuan from the singularity and nourished this space.

He could feel that the moment this space was formed, his strength had skyrocketed by at least thirty times!

This is the Cave Heaven Realm!

This small space is his cave! The stronger the cave sky, the stronger his skills will be!

After the immortal yuan power is released, after meditating for a while, it can be recovered. So Tang Yi didn't care very much, he didn't want to release it like money, this space was also changing a little bit under the infinite immortal power.

The ground is getting thicker, the sky is getting higher.

The space is getting bigger!

A quarter of an hour later, Tang Yi was out of breath, his consciousness withdrew from space, and returned to his body.

At this moment, his immortal yuan power had all been consumed. That small space also had a great change in transmission power, and Tang Yi could feel that he had made great progress.

Even, meat. Since then, his strength has increased dramatically. Now, tightly by virtue of the meat. Body strength, under one punch, is enough for millions of catties!

"Is this the Cave Heaven Realm?"

"It's really powerful, and the current strength is enough to easily kill the previous self."

"I have twelve regiments of immortal yuan, which have not yet condensed into a golden pill, and all of them have become the Cave Heaven Realm, how powerful should it be, don't you want to fly?"

"666, now I'm going to upgrade, self-service upgrade system, upgrade me, upgrade!"

After checking the experience points, there were more than 500,000 more, and Tang Yi chose to upgrade without hesitation.

Ding dong~

"Realm: One Cave Heaven, which can be upgraded, and the next level of two Cave Heavens requires 30,000 experience points!"

The self-service upgrade system gives the upgrade information.

Tang Yi was overjoyed and upgraded the second Cave Heaven, which turned out to be the same as the experience value of the first Cave Heaven, instead of doubling it. This means that he can completely open the cave again, and the experience points are completely sufficient.

"Give me an upgrade, I'm going to open the cave again!"

"Upgrading once, it's upgrading, and ten times is the same upgrade!"

"If I have experience points, if I don't improve my strength, I'll be stupid!"

Before, he hadn't used the self-service upgrade system, all because his cultivation speed had always been fast, and he wanted to lay a solid foundation when he was in the innate realm.

But during this time, his skills have been improving, but his realm has not improved for a long time.

The foundation is solid, but it is difficult to break through.

Now, the opportunity for a breakthrough is just around the corner.

He is constantly upgrading, and Tang Yi's momentum is getting stronger and stronger!

The second hole is open!

Three Caves Heaven Opens!

Four Caves Heaven Opens!

……

The Twelve Caves are open!

By the time the sixth cave was opened, the momentum was already extremely terrifying, and the earth-shattering sound actually pierced out of Tang Yi's body.

As soon as the ninth cave sky opened, black clouds appeared in the sky above the entire Incense Valley.

But Tang Yi upgraded extremely fast, and in a blink of an eye, he opened all the twelve cave heavens.
