After Ye Feng felt the magic of the cosmic boundary wall, he began to return.

After all, his position at this time was as deep as 10,000 kilometers, and all the power of the rules here was of the tenth order.

Although it can withstand it, there is no need to break through in such a dangerous place.

Just a few seconds later, Ye Feng used spatial teleportation to return to a distance of 1,000 kilometers from the cosmic boundary wall.

The power of the rules here is only eight levels, and Ye Feng's current root defense power is not much different from tickling when resisted.

He spread out the roots of the tree, emptying all the power of the rules within a 50-kilometer radius nearby, then took a deep breath and said with some anticipation, "Then let's start!" ”

He clicked open the system panel and lightly clicked the breakthrough button.

In the next moment, the aura on his body began to rise continuously, and for others, the bottleneck that needed to be repeatedly impacted had already broken through in just a few breaths of Ye Feng's place.

But at this time, Ye Feng's spirit was highly concentrated, because with breaking through the bottleneck and successfully entering the ninth order, when the life level was transforming, the realm was also evolving violently.

At this time, Ye Feng's realm naturally spread out, and he was also frantically absorbing the surrounding energy.

When it breaks through, it will be in a very mysterious state, and the energy within a radius of thousands of kilometers will continue to gather towards Ye Feng.

Basically, Ye Feng's realm, how much energy can be absorbed, how much energy can be gathered.

And as the realm absorbed more and more energy, it was also constantly roaring and trembling, as if it was about to evolve from the illusory to the real.

With the passage of time little by little, mountains and rivers gradually appeared in Ye Feng's domain, and these mountains and rivers were all formed by energy.

The appearance of these mountains and rivers has given the whole field a thick atmosphere.

As more and more energy is injected into the realm, these mountains and rivers begin to turn from illusion to reality.

These mountains and rivers first emerged from the middle of the field and spread in all directions.

This is the process of the evolution of the inner heaven and earth.

The larger the Inner Heaven and Earth, the stronger the strength that can burst out after breaking through to the ninth order.

As for how big the inner heaven and earth can be, it depends on the size of the eighth-order realm and the quality of the realm.

Generally speaking, if it is the most ordinary eighth-order powerhouse, this is just a way to comprehend a kind of higher-level rule and evolve the inner heaven and earth.

Then, after his realm is transformed into the inner heaven and earth, the area is only 10% of the original at most.

But if the other party has more than one upper rule, they also feel the rest of the basic rules, median rules, and even upper rules.

Then, depending on the quality, the conversion ratio will be increased to 20% or even 30%.

But in general, there is a limit to this.

Theoretically speaking, an old eighth-order powerhouse has been polished for hundreds of thousands of years, and when he reaches the limit of the eighth-order, he has integrated the three upper-level rules into the realm.

Then, when the realm is transformed into the inner heaven and earth, it is difficult to exceed 50% of the inherited proportion.

Only by special circumstances, or the use of some very special natural treasures, it is possible to break this limit, but it is impossible to go beyond the limit too much.

At this time, the speed of Ye Feng's transformation was extremely fast, and in just 2 hours, the area of the inner heaven and earth reached 50% of the domain.

Obviously, this has exceeded the limit of what an ordinary eighth-order powerhouse can do.

There is no other reason, it's just that the quality of Ye Feng's domain is too high.

The supreme rule is so unreasonable.

However, Ye Feng could also feel that after the scope of the Inner Heaven and Earth reached 50% of the realm, a special force descended, as if to restrict the expansion of the Inner Heaven and Earth.

Although Ye Feng didn't know what kind of energy this was, he had a vague feeling that this was the will of the universe.

This should be the reason why the evolution of the inner heaven and earth to 50% of the original realm will become a limit.

But at this time, Ye Feng could feel the rules of life, and began to fluctuate violently, and began to resist this force.

The constraints on the inner heaven and earth began to weaken and continued to expand outward.

Although the speed of expansion has slowed down, it is a miracle that it can continue to expand despite the restrictions of the will of the universe.

Time is ticking by.

3 hours, 4 hours, 5 hours, 6 hours.

The extent of the expansion of the heaven and earth within the leaf maple is almost stable at an area of 10% per hour.

Therefore, when the time came to the 6th hour, the area of Ye Feng's inner heaven and earth had already reached 90% of the original realm.

But at this time, Ye Feng felt an even more terrifying suppression from the will of the universe.

Vaguely, Ye Feng had a kind of enlightenment, when the area of the inner heaven and earth transformation reached 100% of the realm, then the inner heaven and earth that was born was perfect.

And the perfection of the inner heaven and earth, theoretically speaking, is more difficult to achieve than the perfect realm, and it is also not allowed by the will of the universe.

So for a while, Ye Feng's inner heaven and earth stopped expanding after being suppressed.

Even the rules of life were difficult to break through this suppression, but Ye Feng mastered more than one supreme rule, and at this time, the rules of space also moved.

Before, it was the rules of life that resisted, but now the rules of space have also joined this resistance, and suddenly the inner heaven and earth continued to expand.

Although the speed is slower, the speed of expansion is unusually resolute.

91%、92%、93%…… 99%。

Just when the inner heaven and earth were about to evolve perfectly, the world that Ye Feng was in had changed again.

Countless thunderbolts diffused from all corners of the cosmic boundary wall, gradually converging on the sky above Ye Feng's head.

"Is this a catastrophe?" Ye Feng was a little surprised.

It stands to reason that before becoming a god, unless you have violated some taboos, you will not trigger the heavenly tribulation.

Just like the last time, when Ye Feng triggered the Heavenly Tribulation, he still resurrected the human deity.

This kind of resurrection of dead creatures is something that the will of the universe will never allow, and the Heavenly Tribulation will be born.

But now Ye Feng is just condensing the inner heaven and earth, and he has actually triggered the heavenly tribulation, which can't help but make Ye Feng look forward to it.

Because this proves that the perfect inner heaven and earth are absolutely not ordinary.

As for the danger in the face of the Heavenly Tribulation, Ye Feng didn't care too much.

The so-called will of the universe is actually some kind of operating rule, even if it is the rest of the living beings, the terrifying heavenly tribulation, there will inevitably be a glimmer of life.

For example, his current cultivation has only just broken through to the ninth order, so theoretically, no matter how terrifying the Heavenly Tribulation is, it will only reach the early stage of the tenth order at most.

The Heavenly Thunder Attack at this level may be a catastrophe for the rest of the ninth-order powerhouses, but it is also like that for Ye Feng.

Even when Ye Feng found out that he was about to condense the Heavenly Tribulation, his first reaction was not how to deal with it, but to immediately let the human deity teleport over.

Because the human deity cultivates the Thunder Divine Body, in addition to using the rules of the Thunder System to continuously strengthen the physical body, there is also a way to quickly improve the Thunder Divine Body, that is, the Heavenly Thunder Quenching Body.

Even the Heavenly Thunder that is powerful enough can still cultivate the next stage of the Thunder Divine Body in advance before Ye Feng's realm breaks through.

For example, the Heavenly Thunder, whose power has reached the eighth order, can allow Ye Feng to cultivate in advance, the eighth stage of the Thunder Divine Body.

Now born, according to Ye Feng's estimate, it is a tenth-level heavenly thunder, theoretically speaking, Ye Feng can cultivate the thunder divine body to a perfect realm in one go.

With these thoughts in Ye Feng's mind, in less than 10 seconds, the human deity located at the top of the regular mountain had already penetrated thousands of kilometers into the universe boundary wall and merged with the World Tree itself.

Of course, the human deity is only a seventh-order, and if he is not good at defense, he will definitely not be able to withstand the tenth-order heavenly thunder.

Therefore, Ye Feng came directly to the World Tree itself, located on the trunk in the middle, to avoid facing the Heavenly Tribulation.

At this time, after more than ten seconds of brewing, the power had almost gathered, and suddenly a heavenly thunder more than ten meters thick slashed towards Ye Feng's World Tree.

To be precise, it is towards the inner heaven and earth around the World Tree, which has not yet been fully condensed, and falls down.

Seeing this scene, Ye Feng naturally couldn't sit still, and immediately more than a dozen tree roots rose into the sky, directly meeting this heavenly thunder.

In fact, after reaching the ninth order, the diameter of any of Ye Feng's roots had already exceeded these heavenly thunders.

So at this time, it looked more like Ye Feng was attacking the Thunder Tribulation.

Rumble!

After the thunder and the roots of the tree collided together, they suddenly produced violent energy fluctuations, and thunder and lightning raged on the roots of the tree.

But at best, the bark on the surface is a little scorched, and it does not pose any real threat at all.

"It was easier than I thought." Ye Feng couldn't help but mutter.

Because this Heavenly Thunder is only at the early level of the Ninth Order.

But obviously, there can't be only one thunderbolt, and then one thunderbolt after another falls.

After the initial temptation, Ye Feng only used one root to deal with every thunderbolt.

Moreover, the power of these heavenly thunders, Ye Feng will not completely erase them, and every heavenly thunder will have a part of the thunder and lightning, which will continue to spread down the roots of the tree.

Ye Feng's human deity was waiting below, directly meeting these thunderbolts.

Although these thunderbolts only contained a small part of the power of the heavenly thunder, they were enough to reach the eighth-order level.

After Ye Feng carried it hard, the hairs on his body stood up, and the muscles of his body began to spasm slightly.

But this was exactly what Ye Feng wanted, and he began to use the Thunder Divine Body with all his strength to absorb the power of these heavenly thunders.

The effect of the Heavenly Thunder Quenching Body is much faster than the effect of Ye Feng directly using the Thunder System Rules to quench the body.

Moreover, Ye Feng could perceive that these heavenly thunders seemed to contain the supreme mystery of thunder and lightning, and when his body was absorbing them, Ye Feng's perception of the rules of thunderstorms was also rapidly improving.

This suddenly made Ye Feng's eyes brighten, and he absorbed it more energetically.

In this process, Ye Feng will also constantly adjust the roots of the tree, and the degree of weakening of the heavenly thunder will be as much as possible so that the physical endurance of the human deity has always been on the verge of the limit.

The first wave of thunderstorms had a total of 99 thunderstorms, and it lasted for 5 minutes before it ended.

Looking at the second wave of thunder brewing above his head, Ye Feng slowly exhaled a sigh.

At this time, his human deity was scorched black, and almost every inch of skin on his body was scorched by electricity, but the rising breath on his body did not fall but rose.

A root was placed on Ye Feng's shoulder, and with the injection of life force, the injuries on his body were healing at a terrifying speed.

The charred charcoal lumps on his body also fell off piece by piece, revealing ruddy skin.

"I really didn't expect the harvest to be so big." Ye Feng couldn't help but sigh with emotion.

In just 5 minutes, the eighth stage of the Thunder Divine Body had already completed 50% of its cultivation.

What's more, even his thunderstorm rules have directly broken through to the realm realm, and he has reached the realm double.

In this case, Ye Feng could only sigh with emotion, danger and opportunity coexist, and even for him, there is no danger, only opportunity.

The second wave of the Heavenly Tribulation, after brewing for more than ten seconds, fell with a bang.

It was also 99 Heavenly Thunder, but the power of this wave of thunder robbery directly skyrocketed to the peak of the Ninth Order.

Of course, for the World Tree, there is still no difficulty in resisting it.

And as long as there is no problem on the side of the World Tree itself, there will naturally be no problem with the human deity.

One after another, the heavenly thunder has been "filtered" by the roots of the tree and sent to the human deity, and the power is just right.

After another 5 minutes, the second wave of the Tribulation ended.

Ye Feng's eighth stage Thunder Divine Body had already cultivated to 99%, but he frowned and found that he could not continue to improve.

The reason is also very simple, his thunderstorm rules are only median rules, and the rule perception can't support him for the time being, cultivating the ninth stage of the thunder god body.

This must be realized by him, and the superior rules related to the thunder system can be done.

However, the realm of the Thunderstorm Rules has been greatly improved, and it has been directly upgraded from the second level of the domain realm to the fifth level of the domain realm.

This increase is even more exaggerated than the previous one.

The reason why this is so is naturally because the second thunder tribulation is more powerful, and there are more supreme mysteries contained in it, which makes Ye Feng have more understanding.

At this time, Ye Feng quickly absorbed the life force, recovered the injuries on his body, and looked up at the sky at the same time.

The third wave of thunder tribulation is brewing there, and according to the induction in the dark, this is also the last wave of thunder tribulation.

It's just that might, it is estimated that any ninth-order powerhouse standing here will have a great crisis of life and death.

Even Ye Feng couldn't help but raise his eyebrows slightly, because this power was much greater than he initially expected.

According to his estimates, it should have reached the middle of the tenth order.

You must know that the higher the realm, the greater the gap between each level, and at the level of the tenth order, even if there is only a small difference in rank, the strength will be three or four times different.

However, in the past two months, Ye Feng has been cultivating the Wanmu Divine Body, and although he has not yet reached the realm of Dacheng, he has already integrated more than 600 kinds of strange flowers and fruits into the cell level.

This also made his defense almost double compared to before, although he had not yet reached the middle of the tenth order, but it was not much different.

Coupled with the supernatural powers of the heavens and the earth, it is more than enough to resist such a catastrophe.
