Nie Chen is the master of the cave heaven and the absolute control of the cave heaven world. She asked for resources, and no monk dared to disobey it in the slightest. Although his heart was full of unwillingness, the cultivators still took out everything they had one by one.

This is indeed all, and no monk dares to hide it. They knew Nie Chen's ability, and they knew even more about Nie Chen's control over the Cave Heaven World. lest I hide my own selfishness and bring death to myself.

Nie Chen accepted them one by one, and after thanking the cultivators, he also recorded the materials they took out one by one into the jade slips.

Nie Chen made it clear that these things were borrowed temporarily. As soon as he gets out of trouble, he will return the materials.

Of course, there is a premise for this, that is, Nie Chen can survive this crisis safely. If it falls in the midst of a crisis, then all the previous promises can only become a flash in the pan.

After getting enough materials, Gu Feng immediately began to get busy. Nie Chen is not good at formations, but he is not ignorant. Under Gu Feng's command, he can also make formations. It's just that the technique is not familiar, and the speed is a little slower.

In order to speed up, Nie Chen even found some monks who were good at formation from among the cultivators in the Cave Heaven. There were many monks in the cave, and dozens of people were found after a little screening.

Their cultivation was insufficient, and the speed of making this high-level formation was a few points slower than Nie Chen's. However, the victory is in the large number of people, and when added up, it is faster than Nie Chen and Gu Feng.

For a period of time that followed, everyone had been busy making formations. This process lasted ten days before the materials were exhausted.

After completing their tasks, the cultivators took their own leave and left. Only a mountain-like formation was left, piled up in front of the two.

"It's not bad, I got a total of 110,000 formations, more than 10,000 more than I expected. Now, you control the Cave Heaven Illusion Clone, and I incorporate these formations into it. ”

Nie Chen nodded, and began to prepare according to his words, but he was slightly worried in his heart. That Tu Tian is absolutely extraordinary, once the slightest abnormality is discovered by him, the plan of the two will definitely fail.

Worry is worry, but Nie Chen didn't say it directly. Gu Feng must have thought of this a long time ago, and he would definitely make arrangements.

On top of that, they really don't have any other choice. Even if this plan is a bit risky, it can only be tried.

Otherwise, they would only have to fight with Tu Tian, or hand over Dongtian to beg for mercy. Neither of these two paths will be chosen. They knew in their hearts that it was a dead end.

Where is Nie Chen, he quickly got ready. A hazy ball of light appeared in Nie Chen's hand, carrying the aura unique to the Cave Heaven.

Gu Feng glanced at it, and then cast a spell, and on this ball of light, hundreds of marks were laid one after another. These imprints are used to cover the aura of this ball of light, making it impossible for people to easily detect it, making it more real.

After doing this, Gu Feng waved his hand to put away the formation on one side and hit the ball of light one by one. A small ball of light, but at this time, it seems to have become a bottomless pit. Hundreds of thousands of formations were put in, and there was no hindrance in the slightest.

"Alright, you can go out with it. Remember, keep this ball of light as close to Tu Tian as possible to exert its maximum power. But if it was detected by Tu Tian, it would immediately detonate its internal formation. Otherwise, Tu Tian would make a move, and it would be likely to knock the ball of light away in an instant. That would be a wasted effort. ”

"I know!" Nie Chen agreed, and left the Cave Heaven World.

As for Gu Feng, he didn't follow out. In the past ten days, his cultivation has still been falling, and he is already under the demigod at this time. With such a cultivation, even Tu Tian's coercion could not withstand it, let alone help Nie Chen.

Outside the cave sky, Tu Tian sat cross-legged, floating in the void. Around him, there were countless veins flickering at this time, but it was a large formation.

"What do you mean by that?" Nie Chen glanced at it, his face sinking slightly.

"It's simple, just take precautions. Ten days after you left, I have to suspect that you have other thoughts. In case someone sneaks away, I naturally have to be prepared.

This formation is a trapped formation, and its greatest effect is to lock the void. With the existence of this formation, even if there are some demon spirits with talent space, don't want to escape quietly. Tu Tian sneered, meaning something.

Obviously, he knew that there was a blue butterfly by Nie Chen's side. This formation that locked the void was to prevent Nie Chen from escaping secretly.

He didn't know that Nie Chen didn't have this plan at all. Although the blue butterfly can accommodate the void, there are many restrictions in this Nine Secluded Land. If you really do that, I'm afraid that before you leave this soul source space, you will be detected and intercepted by Tu Tian.

"You're thinking too much, how could I sneak away. Don't forget, there are commitments between us. Nie Chen snorted in response.

"Since you have spoken of promises, you can give me the Purple Cloud Cave Heaven now, right?" Tu Tian asked.

Nie Chen sighed: "Okay, I'll give it to you." But you have to promise that after you get the treasure, you will let us go safely!"

"Naturally, there is no problem with this. Tu Tian agreed, but a trace of coldness flashed in his eyes.

Nie Chen's existence has become a big threat to him. If he is given a chance, he will naturally cut the grass and eradicate the roots. As for the promise, it was just a word for him. Even if he breaks his promise, who can help himself.

Nie Chen didn't say much, waved his hand and took out the ball of light. He glanced at it reluctantly and threw it gently towards Tu Tian.

At the same time, Nie Chen's cultivation realm began to be unstable, and there were faint signs of falling. This was deliberately exposed by Nie Chen, in order to echo the separation of the Purple Cloud Cave Heaven.

"This can't be fake, right?" Tu Tian glanced at the balls, and a sneer appeared on the corner of his mouth.
