The third wave of thunder tribulation hadn't yet descended, and the momentum of Shuaiguo was rising crazily. Mo Wuji knew that Shuaiguo was about to advance. Based on Shuaiguo's trend in enduring the tribulation, this thunder tribulation shouldn't pose much of a threat.

Sure enough, as Shuaiguo's momentum increased, the third and fourth waves of thunder arcs only managed to singe some of Shuaiguo's feathers.

Before the fifth wave of thunder tribulation even fell, Mo Wuji knew that the subsequent thunder arcs wouldn't have much impact on Shuaiguo.

Just when Mo Wuji thought Shuaiguo's tribulation would end just like that, he suddenly sensed some changes in the surrounding space. However, in this place, his spiritual will simply couldn't scan what those changes were.

Mo Wuji saw Shuaiguo open its mouth again. Without thinking, he directly condensed his Spiritual Eye.

Under the Spiritual Eye, gray, dim auras that even spiritual will couldn't detect were being sucked away by Shuaiguo like a whale inhaling water. The surrounding space seemed to have undergone some changes; at least, Mo Wuji felt much more comfortable, without the oppressive feeling he had before.

After a few more waves of thunder arcs fell, Shuaiguo directly advanced to a Fourth Grade Immortal Beast. The subsequent waves of thunder tribulation indeed had no effect on it whatsoever. But whether during the tribulation or after, Shuaiguo was constantly opening its mouth, frantically devouring the surrounding aura.

Under Mo Wuji's Spiritual Eye, that gray aura carried a chilling suppression, even a feeling of nibilating the Dao foundation. It was completely an aura of death.

A thought suddenly struck Mo Wuji. He took a step and appeared beside Shuaiguo.

Shuaiguo quickly stopped absorbing the gray aura, saying sheepishly, "Grandpa, I'm a Fourth Grade Immortal Beast now."

It was worried that Mo Wuji would scold it for being an idiot, daring to devour thunder tribulation arcs.

Mo Wuji waved his hand, "Continue to devour that gray aura from before."

"Okay, this aura tastes pretty good, you know. After I eat it, I feel my strength increasing quickly," Shuaiguo said proudly, hearing that Mo Wuji wasn't scolding him.

After saying that, it seemed to sense that Grandpa was in a bad mood, so it didn't dare to talk nonsense. It opened its mouth again and inhaled.

This time, Mo Wuji sensed it even more clearly. Shuaiguo could indeed devour the oppressive gray aura here. As Shuaiguo continued to devour this aura, Mo Wuji felt the surrounding space becoming clearer and clearer. Before, his spiritual will was somewhat blurry, but after Shuaiguo devoured this aura, the effects on his spiritual will rapidly decreased. Mo Wuji even suspected that once Shuaiguo devoured all of the cold, gray aura here, the spatial restriction would disappear.

Shuaiguo didn't know how it was doing it, but it could actually absorb the surrounding gray, cold aura. Even though Mo Wuji's strength was much greater than Shuaiguo's, he could only sense it; he couldn't touch it at all.

Mo Wuji's spiritual will tentatively landed on the gray aura that Shuaiguo had absorbed, and immediately, he was shocked. In just a moment, he felt some stagnation in his meridians.

"I understand," Mo Wuji murmured to himself.

He understood why there were so few Immortal Emperors here, and he understood why some people disappeared quickly after entering the Gobi Desert of the Outer Heaven Corridor.

In this Gobi Desert, there was a powerful aura of death that nibilated cultivation, the same gray, cold aura that Shuaiguo was eating. When this aura was devoured by Shuaiguo, the surrounding space became much more comfortable for cultivators.

If ordinary cultivators didn't have an Undying World, they wouldn't be able to last long in this place, even if they didn't cultivate. Because their cultivation would be constantly eroded away, and their Dao foundation would be nibilated.

The reason why the Outer Heaven Market could exist was because there was no such gray aura in that area, or it was extremely rare.

Mo Wuji tried to continue absorbing this aura to cultivate. He wanted to know how powerful this gray aura was at nibilating his spiritual roots and meridians.

Soon, Mo Wuji was pleasantly surprised to discover that although this aura caused some stagnation immediately after being absorbed, after passing through his poison transformation meridian, all of this aura was transformed into immortal spiritual energy, and only a very small portion of the shadowy aura that nibilated the Dao foundation was directly discarded. In other words, even if he didn't have an Undying World, this place couldn't do anything to him.

Mo Wuji, who had been considering a place to cultivate, was now completely at ease. His Undying World was incomplete and couldn't sense the laws of heaven and earth. Since this place had no effect on his cultivation, he would naturally cultivate here.

An hour later, Mo Wuji took Shuaiguo into the depths of the underground. Deep beneath the Outer Heaven Corridor, he set up a cave dwelling. Shuaiguo didn't enter the Undying World either. It was frantically absorbing the gray aura of this place under a pile of azure crystals, immortal crystals, and various immortal pills. Its strength was also increasing rapidly.

The first thing Mo Wuji did wasn't to cultivate. He opened Ou Zhaohe's storage ring. Although a million azure crystals weren't much compared to him, it was definitely considered wealthy. Besides the million azure crystals, Mo Wuji also found dozens of top-grade forging materials in Ou Zhaohe's ring, and even a Ninth Grade flying immortal artifact, the Shadowless Shuttle.

The Profound Yang Seal was an immortal artifact that exceeded Ninth Grade. Mo Wuji hadn't refined it yet, but he knew that it wouldn't be weaker than his Half-Moon Heavy Halberd.

Although there were no earth-shattering treasures, the harvest from this ring had already made Mo Wuji very satisfied.

After sorting everything out, Mo Wuji took out the six pages of River Luo. He knew that Murong Xiangyu needed these pages the most urgently, but Mo Wuji didn't plan to hand them over to her. If it was Cen Shuyin or Han Qingru who needed the River Luo, Mo Wuji would have taken out these six pages without hesitation. As for Murong Xiangyu, she could forget about it.

Mo Wuji's spiritual will was extremely strong, and he also had the Spirit Storage Meridian. Refining the River Luo in the Immortal Reverent Realm was many times faster than before.

Layer after layer of innate restrictions were opened by Mo Wuji, and Mo Wuji was completely immersed in the process of refining the River Luo.

……

The Universe Corner Immortal Rest Building in Universe Corner was considered a first-class Immortal Rest Building.

No one knew the background of this Immortal Rest Building, but its reputation in Universe Corner had always been very good. Any grudges would cease once you entered this Immortal Rest Building, and no one would bother you. Moreover, the soundproofing restrictions in the Outer Heaven Universe was second to none. No matter what you discussed here, it wouldn't be leaked.

At this moment, in a medium-sized private room in the Universe Corner Immortal Rest Building, two middle-aged men were sitting inside. Neither of them spoke, seemingly waiting for someone.

Sure enough, in less than half an incense stick of time, the restriction at the entrance of the private room moved, and then an old man came in.

As soon as the old man entered the private room, he casually placed a restriction on the room, and at the same time, he bowed and said, "Fei Cheng greets the two young masters."

"Uncle Cheng, please sit down quickly." The two middle-aged men who were sitting stood up with smiles on their faces.

These two middle-aged men were none other than Jin Yu and Jin Yiren of the Jin family. In a place like Universe Corner, many people wore masks when they came here, so they naturally wore masks as well.

The old man was the Jin family's steward, Jin Fei Cheng. Knowing that the two young masters had something to ask of him, he also wore a mask.

"Yes, please instruct me, two young masters." Jin Fei Cheng didn't mind and sat down. Jin Yu and Jin Yiren had both grown up under his watchful eyes, and he considered them family.

"Uncle Cheng, take a look at this duel image first." After Jin Yu finished speaking, he took out a crystal ball, casually cast a few hand seals, and a slightly blurred duel image appeared in the air.

This was clearly the duel image of Mo Wuji and the three Immortal Emperors of the Mi Fei Merchant Association. Although the faces of the people weren't very clear, the process of the duel was extremely clear.

"Is this the previous Dan Master Mo Wuji? Rumor has it that he killed the three Immortal Emperors of the Mi Fei Merchant Association…" Jin Fei Cheng said in surprise after seeing the duel image.

Jin Yu nodded. "Yes, Uncle Cheng, you are in the late stage of the Immortal Emperor Realm, and your strength should be about the same as that Ou Zhaohe. What do you think of this Mo Wuji's strength?"

"The two young masters want to deal with this person?" Jin Fei Cheng immediately understood what they were getting at when he heard this.

Jin Yiren snorted and said, "This person snatched my Jin family's treasure from me. It's hard to calm my anger if I don't kill him."

Jin Yu said calmly, "There's nothing that can't be said in front of Uncle Cheng. This person snatched at least ten Chaos Fire Mother Crystals from Yiren, and he also has a great secret of cultivation on him. Besides that, he swept away seven or eight million azure crystals, as well as various top-grade immortal spiritual herbs and ores, in the Outer Heaven Market this time."

Jin Fei Cheng gasped when he heard this. Seven or eight million azure crystals were considered top-tier wealthy even in Universe Corner.

After knowing what the two young masters were thinking, Jin Fei Cheng said in a deep voice, "According to the duel image, he should still be in the Outer Heaven Corridor. The void of the Outer Heaven Corridor can't be torn apart. He escaped from the crack, and he won't be able to return to the Human Corridor or the Demon Corridor in the short term. His range should be in the Western Wastelands of the corridor.

The Five Elements Chaos Mother Crystal has the effect of suppressing the nibilating Dao foundation aura of death in the Outer Heaven Corridor, so this person's cultivation and life won't be affected in the short term. Also, since he has offended the Mi Fei Merchant Association, he won't go to the Demon Corridor or the Human Corridor in the short term, and he won't come to Universe Corner. If we want to deal with this person, we just need to go to the Western Wastelands."

Jin Yu nodded. Jin Fei Cheng's analysis was the same as what he thought.

"According to this person's duel process, this person relied on the self-destruction of a killing array to kill Ou Zhaohe and Ling Rong. This shows that this person is a master of immortal arrays, and he's also a body tempering expert. I estimate that this person should be a body tempering expert in the late stage of the Divine Body Realm. If we want to deal with this person, we can't be in his killing array." Jin Fei Cheng's tone became serious.

Jin Yu said, "That's right, but this person's strength shouldn't be very high. I suspect that he hasn't even entered the Emperor Realm."

Jin Fei Cheng shook his head. "It doesn't matter whether he has entered the Emperor Realm or not. What matters is his strength. His strength should be around the middle stage of the Immortal Emperor Realm. If he doesn't rely on the self-destruction of the array, he's not Young Master Yu's opponent."

"I know he's not my opponent, but this person is extremely slippery. I called Uncle Cheng here to figure out how to trap him so that he can't escape," Jin Yu said in a deep voice.

"This matter is easy. You just need to borrow something first. The most difficult thing now is to find this person first," Jin Fei Cheng smiled faintly.

Jin Yu's eyes lit up. He understood what Uncle Cheng meant.
