Fang Rui wasn't worried that if he wanted to break the barrier, it would cause too much damage to this barrier, after all, it was a relic left by a top-level Immortal Monarch, and it would definitely not be something that he, a small fifth-grade cultivator, could break, all he had to do was just open a passage.

However, Fang Rui quickly discovered that it was not so simple - if it was to shoot with his divine sense, such a long passage would not be so light that it could be opened, after Fang Rui's divine sense blasted open a path, he turned his head and saw that the barrier behind him had been filled - this barrier also had a strong self-healing function!

However, Fang Rui was not discouraged by this, but was even more happy - this was naturally very good, and it could heal itself, so that if Fang Rui really opened a passage, the spiritual energy in the Clear Void Cave Heaven would continue to leak out, but it would make the Clear Void Cave Heaven become depleted......

Obviously, this is also in the consideration of the Almighty Immortal Monarch.

Fang Rui withdrew his divine sense and looked at the barrier in front of him.

He couldn't enter this barrier, but what if he bombarded it with mana? Can he break this barrier at a certain point, allowing some of the aura inside to leak out? and then bombard again after the barrier heals itself...... Until the aura that leaks out makes you satisfied.

Thinking of this, Fang Rui raised his hand and laid down a prohibition—a monk of a grade can lay down such a prohibition to isolate something, just like when the fourth-grade demon cultivator assassinated Tian Rufeng and them, although it was in a place like Jixia Academy, where Crouching Tiger, Hidden Dragon was, it would not be discovered by others.

Fang Rui's deployment was a defensive prohibition, which was to prevent him from hitting other places when he was bombarded with spells.

After placing the ban, Fang Rui thought for a moment, stretched out his right index finger, and a sharp golden qi appeared on his finger, shooting at the entrance of the Clear Void Cave Heaven!

Ruijin's qi is sharp and incomparable, and it is naturally Fang Rui's first choice.

However, after this sharp gold qi came into contact with the entrance, it passed directly through with a "whoosh", and then crossed the entrance and directly hit the prohibition under Fang Rui's cloth.

This entrance is actually powerless!

Fang Rui's face remained unchanged, he naturally knew that it was not so easy, the next moment, he concentrated the huge Yuan Force that the entire Unified Seal had absorbed, all of which was compressed into a hair-thin sharp gold power, and stabbed towards the entrance again!

The result was the same, different forces, the same result, this huge sharp gold power directly passed through the entrance, and slammed into the prohibition arranged by Fang Rui......

If it weren't for the fact that the two Yuan Qi came from Fang Rui's body at the same time, this blow alone would shatter the prohibition that Fang Rui had laid out!

"I can't help it...... Completely unbeatable...... No, it's just not fast enough. ”

Fang Rui thought so, and then he raised his hand and struck out a wind blade.

The attack speed of the Wind Blade was the fastest among the nine systems, cutting into space with speed, this was Fang Rui's idea.

However, the Wind Blade also slid through the barrier, striking directly into the prohibition.

Turbulent water, scorching fireballs, heavy earth shields...... Fang Rui tested the nine series of spells one by one, but he couldn't attack the main body of the barrier, it seemed to be standing there, but it didn't seem to belong to this space at all, no matter how he attacked, it couldn't make it shake in the slightest.

Obviously, this is not something that can be done with a simple spell bombardment.

Fang Rui fell into deep thought again, he believed that there would be a way—in the midst of such a strong thought, an idea popped up in his mind.

Since this space is the same as himself, there are no nine veins, and the all-powerful all-powerful Immortal Monarch of the nine lines is left behind, so could it be the same as when he got the inheritance before, and he needs to show this characteristic of himself in order to be able to master the key to open this door?

If you are the inheritor, then you should completely own the Clear Void Cave Heaven, rather than just passively accepting the gift of the Clear Void Cave Heaven.

If you want to do this, you have to show your strength!

Letting the nine spells unify, this is not something that can be done lightly, and it can even be said that this is simply a way to subvert the cultivation system of the Flying Immortal Continent, but since he is a strange person who can use nine kinds of spells, why not try to do such a thing?

Integrating spells with similar attributes, this is what Fang Rui has been doing, just when he was a cultivator in the innate stage, he was able to infuse the power of thunder and lightning into the power of Ruijin, increase the lethality of the spells, and combine the earth spells with the wood spells to enhance the defensive ability, but that was just to let the spells with similar attributes cooperate, and let the spells with similar attributes to fight each other together, such a thing, Fang Rui had never done such a thing.

It's just that Hongfeng can combine the two series of spells of water and fire, which proves that even if it is a spell that clashes against each other, it can also be fused together, after all, no matter how the spells clash with each other, the origin also comes from itself, providing the foundation for doing so.

Chaos Gas.

Fang Rui once again thought of the Heaven and Earth Yuan Qi in his body that could return to its origin, but he had used Chaos Qi before, just to hide the aura, and freely transform it to cause additional lethality when attacking, now what he had to explore was probably to make the Chaos Qi be able to show the characteristics of nine spells in an instant!

"Wind, thunder, metal, water!"

Fang Rui let out a low snort, and a cloud of chaotic qi appeared in his palm, wind and thunder intersected, and the source of gold and water perfectly appeared in this chaotic qi at the same time.

However, Fang Rui did not relax there, these four Yuan Qi could originally be fused with each other, and what was really difficult was to let other Yuan Qi also merge into it......

"Wood, earth, yin!"

Another cloud of chaotic qi also appeared in his palm, and the three systems of spells were entangled, clearly distinguishing and merging with each other.

"Yang!

The third group of chaotic qi appeared in front of him, which was also the most difficult to fuse into the other two groups of chaotic qi, yin and yang repelled each other, and fire was even more difficult to fuse with the two systems of water and earth, and the two systems of water and soil were the key to the first two groups of chaotic qi being able to fuse together.

When these three chaotic qi came into contact with each other, there was immediately a chain reaction-like explosion, and Fang Rui didn't check for a while, and he was blown up......

Wiping his face, Fang Rui found that he was a little underestimated, if he wanted the nine systems to be one, he definitely didn't just mix these nine kinds of vitality together.

Only by allowing the nine kinds of vitality to merge with each other, but with a clear distinction, although the inside is very unstable, the outside is as stable as Mount Tai, so that you can burst out of huge pressure at the same time when you come into contact with the enemy - if you can do this, then not only can you break the barrier, but also when you are facing the enemy, it will also be of great help!

The blow that he had defeated Red Maple before was to concentrate nine different spells, and when he approached the other party, he forcibly fused them together to form a strong explosion, and this blow seriously injured a five-rank peak monk like Red Maple, which was also a train of thought.

Thinking of this, Fang Rui's fingers stretched out and drew a small spirit gathering array in the air.

Then he began to inject spells into the Spirit Gathering Array one by one, carefully so that they did not come into contact with each other as he did so......

This was a very sophisticated approach, Fang Rui did not let his Yuan Ying help, but controlled these spells with the power of one person, allowing them to wander around in a small area, but did not touch each other......

Of course, this is a very difficult thing, after the spell is attacked, the monk can only control the direction in which it is going, but cannot let it stay in place, Fang Rui can only make the chaotic qi cause such an effect, if he wants to cause the maximum lethality in the smallest range, he has to do this.

It's like making firecrackers.

It is a very difficult thing to think about the nine different spells that constantly rotate forward and swim in a small space, but do not collide with each other, and the slightest collision of the two spells will cause a chain reaction explosion.

However, this kind of control is very helpful for the monk's control of the force, and this kind of control is very likely to have a greater effect on the enemy.

Fortunately, Fang Rui is very experienced in this kind of subtle control - when he was stagnant in the congenital period for more than two years, Fang Rui has been striving for excellence on the road of "art" and laying a good foundation, although it has been making rapid progress for more than a year, but the foundation is still there, after a day of continuous failure, Fang Rui finally reached a perfect control!

For a monk, as long as there is a perfect control, then his body and mind will be firmly remembered!

In the small space, nine different spells flew back and forth in a loop, but there was no touch, the instability in the inside, and the stability in the appearance.

At this moment, Fang Rui knew that his combat power had improved again, once such a nine-series spell started, the power was not only comparable to a single-system spell!

Now Fang Rui can only control such a small range, but when he becomes more and more proficient, if it is nine spells that he attacks with all his strength and then attacks them like this, let alone a sixth-grade monk, even if it is a seventh-grade monk, I am afraid it will not be beneficial!

And this kind of spell will have greater power with the improvement of one's mana, and what kind of monk can challenge oneself who can leapfrog the challenge, after having such a powerful spell?

Now, you can take the barrier left by the Almighty Immortal Monarch and test the power of this spell!

Fang Rui took a deep breath, the small ball floated in front of him, and then as Fang Rui's mind turned sharply, the small ball rushed towards the barrier of the Clear Void Cave Heaven at lightning speed!

"Boom!"

With Fang Rui's shout, the small ball flew to the barrier like a meteor, and the moment it touched the barrier, Fang Rui let go of the control of the spell, and the nine series of spells were instantly entangled together, and then there was a violent explosion!

Fang Rui knew the situation inside the small ball, and when the explosion occurred, he withdrew the small Spirit Gathering Array, allowing all the power to burst out without hindrance!

Then Fang Rui saw that at the entrance of the Clear Void Cave Heaven, there was a ripple like a water wave, and a small black hole appeared at the entrance, and then, an unfathomable huge aura poured out towards the outside!

"Success!" Fang Rui clenched his fists and couldn't help but wave it violently - although it was only to break the barrier, for Fang Rui, this was undoubtedly a huge victory!

A large amount of spiritual energy swept out from the Qingxu Cave Heaven, after all, compared to the original situation of this room without any spiritual energy, the spiritual energy in the Qingxu Cave was so thick that it was like a substance, under the impact of such a massive amount of spiritual energy, the house cast by the black stone was unable to block the leakage of spiritual energy for a while, and a strong spiritual energy rushed straight to the sky from the roof, until it was stopped by the Spirit Gathering Array above the Fang family's station, and then it dissipated......

And just this momentary leak has attracted the attention of some people.
