The reason why he did this was because Cao Fan had an extremely bold idea in his heart.

He wants to refine the Thunder Mist Ancient Palace!

This Thunder Mist Ancient Hall is quite large, and the level is very high, so it can't even be regarded as a thing in the cultivation realm. With Cao Fan's Taoism, refining it would have been a fool's dream.

But when he was trapped in the cyan giant monument, with his experience in controlling the Taishang Nine Realms, he keenly felt that this giant monument was the control center of the entire Thunder Mist Ancient Palace.

If it is directly refined from the periphery of the Thunder Mist Ancient Palace, it is an earth immortal powerhouse, and I am afraid that it will not be able to refine it with the strength of a lifetime.

But from the time of controlling the refining of the center, the situation was completely different, and the scope was much smaller than the entire Thunder Mist Ancient Palace.

In addition, there were two most important reasons why Cao Fan chose to refine the Thunder Mist Ancient Palace.

On the one hand, after the control center was blasted open by Cao Fan with the power of faith, it was no longer monolithic, and it was much less difficult to refine.

On the other hand, when Cao Fan used a large amount of faith power to bombard the inner wall of the giant monument before, almost all of the faith power of the first six attacks was absorbed by the giant monument space.

The defense mechanism of the monument space is to absorb and fuse most of the attack energy to resolve the damage it receives.

The power of faith and the power of the general true element are completely two concepts, and as soon as the giant monument space is fused with the power of faith, it is branded with Cao Fan, which is equivalent to Cao Fan using so much power of faith to refine the cyan giant monument, or rather, to refine the Thunder Mist Ancient Palace.

Cao Fan felt the changes in the power of these beliefs, and this was the reason why he moved his mind to refine the entire Thunder Mist Ancient Palace.

He estimated that after these powers of faith were absorbed by the giant monument space, it was equivalent to that he had refined about 45% of the Thunder Mist Ancient Palace. And as long as he was able to refine to 50% of the progress, he would be able to barely accept the Thunder Mist Ancient Hall into his Taishang Nine Realms.

At this point, Cao Fan had absolutely no reason to give up the upcoming Thunder Mist Ancient Palace.

Cao Fan was not afraid that he would be attacked by the eight immortal chains again. He had refined the control center to more than forty percent, and it was impossible for these chains to continue to attack him again.

Sure enough, when Cao Fan entered the interior of the giant monument space again, all the eight locks honestly didn't bother to come to him again.

He could even communicate these immortal chains for his own use.

It wasn't until he tried to refine the cyan giant monument that Cao Fan knew how naïve his idea of refining the Thunder Mist Ancient Hall was.

With his cultivation, even if he spent the last half a year, I am afraid that he would not be able to refine one percent of the progress.

It's a pity that the power of faith in the Taishang Nine Realms has almost been completely exhausted, otherwise it would have been much easier for Cao Fan to refine the control center of the Thunder Mist Ancient Hall with the help of the power of faith.

Despite this, Cao Fan was still refining the cyan giant monument with all his might. Until the last minute, he didn't want to give up this huge opportunity.

Once this Thunder Mist Ancient Hall is successfully refined, it can definitely become a top-level magic weapon and another sharp killer weapon for Cao Fan.

Seven or eight days later, Long Yin and the others came out of the Taishang Nine Realms and cultivated directly on the flat ground at the bottom of the giant monument.

The immortal aura here is so good, if they practice here for one more day, they will make a lot of money.

The dry bones Cao Fan hanging in the giant monument were all collected into the Taishang Nine Realms, and let them settle in the ground.

Zhuo Yao was very lucky, Cao Fan rescued him casually and sent him into his true spirit world. Otherwise, he would have been sucked dry by the red light, and eventually turned into a dry bone.

However, after Zhuo Yao disappeared, the red light that had originally absorbed his flesh and blood suddenly reversed direction and rushed towards Cao Fan.

Obviously, the things in this red light did not belong to the cyan giant monument, or rather, they did not belong to the Thunder Mist Ancient Palace. Otherwise, he would never attack Cao Fan at this time.

This thing is fast, cruel, and powerful, if it is in normal times, Cao Fan really has no way to dodge its crazy attack except to escape into the Taishang Nine Realms.

But now, Cao Fan is not worth it at all.

As soon as his mind moved, the eight immortal chains waved again.

Only this time, the target they dealt with was no longer Cao Fan, but that weird red light.

This chain can be thick or thin, and as soon as the red light falls under the heavy interception of the eight immortal weapons, it is locked layer by layer, where can it still move?

It was only then that Cao Fan finally saw clearly what was inside the red light.

It turned out to be a strange insect with a red body.

The strange insect resembles a centipede in appearance, but its body is much longer than a centipede, about a foot long, and there are many pairs of wings on its back.

It was this thing that killed the dozens of Tianjiao monks who "ascended to the sky in one step".

The eight immortal chains contracted rapidly under Cao Fan's control, and the strange insect finally let out a series of piercing angry screams, and struggled violently in desperation.

Cao Fan was seven or eight zhang away from the strange insect, and he could feel that the huge force set off by the other party was extremely amazing, far exceeding that of ordinary Mahayana monks.

If it was just two or three immortal chains trapping each other, it would really let the strange worm break free.

Unfortunately, it was faced with eight chains, and no matter how much it struggled, it could not get out of it except to shake the chains violently.

The chains shrank tighter and tighter, and the screams of the strange insects became more and more desperate.

The two sides stalemate for seven days, and finally the chains contracted to the extreme, twisting the strange insect into countless pieces.

Blood light sprayed out, permeating the space of the giant monument, and Cao Fan's brows couldn't help but wrinkle.

When refining the cyan giant monument before, Cao Fan had already discovered that there were still traces of being refined by other people here.

Fortunately, the other party's progress is only about 10%, and the gap with him is quite large, so Cao Fan didn't pay attention to it.

But when the blood on the strange insect spilled into the giant monument space, Cao Fan was surprised to find that the progress of that refining trace had actually increased rapidly.

By the time those blood were completely absorbed by the giant monument space, the refining effect of that refining trace had actually increased to 39%.

Cao Fan finally understood.

This should be the power of a certain upper realm that can't refine the Thunder Mist Ancient Palace, so he came up with such a move. Place the Thunder Mist Ancient Hall in the cultivation realm where the rules of heaven and earth are relatively low, and use this strange insect to refine the Thunder Mist Ancient Palace.

The other party should adopt the method of blood sacrifice, so that this strange insect can absorb the essence blood of the top genius and continue to grow itself. When the monster insect grows to a large enough extent, it should explode its body and sacrifice the cyan monument with blood.

This strange insect must have been marked with a special ban and its own brand by that power. The Monster Worm Blood Sacrifice Monument has the same refining effect as the one obtained by refining the power.

Cao Fan is just guessing at this point, and he doesn't know what the real situation is.

......

Celestial.

In the Tianyang Immortal Gate, in an immortal palace in the Ethereal Immortal Peak, a young man wearing a green dragon crown and a purple and gold robe stood up from his seat, his expression full of anger.
