Together with the Three Spirits, Caracer explores the Iron Dragon Cave and discovers the greatest secret: all above-ground facilities, from construction to maintenance, are inseparable from the Brown Blood Pool, which is buried deep underground.

And at first glance, it seems that the energy supply of the facilities comes from outside the Sky Cloud Condensation Zone, but in fact, even if the energy sources of the first two zones are all cut off, they can operate independently. This disguise deceived Xi Mutong, but it did not deceive the new four spirits who came here to explore the way.

If you want to clamp Nangong Xiang, if you hit his throat with one move, you have to cut off all his ways of life. Outside the Tianyun Condensation Area, Xi Mutong led the Vast Eagle Beacon Camp to break the formation everywhere, and the four of them remained silent, secretly taking on the responsibility of cracking the Iron Dragon Cave.

After figuring out the basic situation, the four of them made a division of labor, and Sanling was responsible for the part under the brown blood pool, ensuring that the pool could be dried up before the army attacked.

On the Brown Blood Pool, the Iron Dragon Nest and the Tianyi Pavilion are the most important, and the caracal clone lacks skills, and he thinks that the Iron Dragon is facing the Yunxiao battlefield, and the dragon is far away on Fuyu Island in the South China Sea, and it is better to leave it to the Condor team participating in the Yunxiao decisive battle, and he himself is in the Tianyi Pavilion to study the world-destroying instrument to see what can be done, so as to block Nangong Xiang at a critical moment and give the divine soldiers enough time to capture the thief.

When the three spirits entered the Void Cold Valley with him, there were only three days left before the night of the Snow Wolf Weeping Moon. It was not easy to accomplish such a heavy task in three days.

As the ethereal monk said, he and Lancang Niangniang and Yunjian sneaked under the brown blood pool, and saw that the pool water covered the entire bottom of the Void Cold Valley, and the magnificent spectacle entered a strange place similar to the "lotus pond".

There were no lotus flowers to be seen in that place, only large patches of round gray-green plants like lotus leaves growing at the bottom of the water. At first, they thought it was algae, and the ethereal monk planned to pick a piece and take it ashore to study, but as soon as it floated over, it was sucked onto the disc and fainted.

Lancang Niangniang and Sword Immortal were shocked when they saw this, and hurried over to rescue each other, but they also encountered the same attack, and they both lost consciousness.

It was this experience that allowed them to meet Han Xuzi, who was brutally killed by Nangong Xiang. After the evil god died, his soul precipitated at the bottom of the brown blood pool, and these green algae plants were born and used by Nangong Xiang to heal his wounds. Because a stranger broke in, Han Xuzi's soul was disturbed, and he counterattacked through green algae, creating an opportunity for the four of them to meet.

After that, how the four spirits told the sleeping ghost about Nangong Xiang's evil deeds, and persuaded him to jointly exterminate this evil thief, there is no need to elaborate. It is only said that Han Xuzi is a quirk by nature, and he didn't like to associate with anyone before his death, and at this time, in order to avenge his death, he can no longer refuse the three spirits thousands of miles away. And after being lonely for so many years after his death, once he was awakened, he was afraid of loneliness, afraid that he would continue to sleep in his dantian like this, and there would be no time to see the light of day again.

So Sanling made a promise that as long as he could cut off the water source of the Brown Blood Pool and give Nangong Lai a salary, he would promise to come back to him and take him to find the path of rebirth.

The three spirits' actions under the pond were successful, and the caracal was happy to hear it, but he didn't know about the deal between them and Han Xuzi.

In the Tianyi Pavilion, he didn't dare to touch the various mechanisms of the Tianyi in vain, for fear that he would start the heaven-destroying procedure instead, so he could only put his mind on the water fetching system. Unexpectedly, cutting off the groundwater upward, the celestial sphere really changed, breaking away from the pedestal and rising above the heads of the four brass dragons.

He quietly studied whether the celestial sphere was good or bad, and finally came to the conclusion that after the ball left the pedestal, it would lose its stability, and it was originally controlled by the four small dragons, but now without the support of the water system, it was in a semi-uncontrollable state.
