The underground palace was astonishingly deep as it was. After walking in the strong turbid air for a long time, the passage was still as narrow as it was at the beginning. Yun Che remained in a state of hidden shadow and thunder, and followed carefully behind the three of them, unable to get around. Although he became more and more uneasy, he was not impatient.

"Why isn't it going to the end yet? How deep is it here?"

"The turbid air is getting heavier and heavier... The passage is getting flat and should be about to reach the exit."

"Wait...what does this taste?"

"It's very poisonous! Go back quickly!!"

The sound coming from the front suddenly changed drastically, and the breath of the three kings of the realm suddenly approached the direction where Yun Che was. Yun Che was shocked and stopped, but did not retreat at a loss, but instead stood firm in place and held his breath... Fortunately, the breath of the three kings of the realm also stopped immediately, and then stopped there, and did not discover his existence because of the sudden closer distance.

Very poisonous? Yun Che slowly stepped back and his eyebrows moved.

In front of the three kings of the realms, there was a thick layer of dark green in the thick gray air. These dark greens filled the passages ahead, floating slowly like smoke, but it seemed to be locked in that area and did not escape outward.

Mu Baimei, Emperor Nan Lie, and Han Kuan stood in front of the poisonous fog, and their expressions were very bad. They quickly got lucky to drive away the poison. After a while, their faces finally became more normal.

"What a powerful poison! If the reaction is slower, I'm afraid I'll explain it here." Han Kuan said with lingering fear.

"After all, it is something left over from ancient times." Emperor Nan Lie took a step back a little. Countless years have passed since the Age of the Gods, and the poisonous fog here should have naturally dissipated and diluted countless times, but it is still not something that ordinary people can easily bear.

"The turbid air here suppresses the mysterious power, and it is a bit difficult to deal with when encountering such poison again." Mu Bai's eyebrows frowned.

"Do you want to try and break through directly?" Han Kuan said suddenly.

"If Master Han thinks his life is long, you can try it." Emperor Nan Lie said in a faint voice: "I don't know where this poisonous fog spreads. If it lasts for several miles, I'm afraid I'll have the chance to go in and come out."

Yun Che listened silently to their voices and understood what they had encountered... At the end of the passage, there was a poisonous fog area. Moreover, the terrifying poisonous fog made these three kings deeply afraid and could not continue to move forward.

boom!!

A burst of explosion came from the front, and the underground palace passage trembled slightly, followed by the disappointed voice of Emperor Nan Lie: "No, it cannot be shaken away at all."

"If you want to pass through such a powerful poison safely, at least you have to be able to do it. Could it be that we can only hand over the Immortal Grass to the people in the middle astral realm?"

"Do you want to try to find other entrances?"

"Even if there are really other entrances, it's too late. The news has been spreading for so long, and within six hours at most, people from the middle or even the upper astral realm will arrive. It took us a whole day to break the seal of this entrance. It would be better to give up someone to find other entrances!"

"Then what if I try to break through? Maybe this poisonous fog is not as vast as we thought."

"Very good. Then please Master Han first. Although the Imperial Grass is good, if you want to bet on your life, I will definitely not do it."

The three kings of the realm, the figure who covered the sky with one hand in the three realms, were blocked by a poisonous fog. They all felt that the Immortal Grass was close at hand, but they could no longer move forward. The power of the unparalleled God King was useless in front of this poisonous fog.

But they were never willing to turn around and leave. Putting aside the huge temptation of the Immortal Grass, they had paid a huge price to blow open the entrance of the underground palace. How could they be willing to fail?

Yun Che's mind changed rapidly, and several possibilities emerged in his mind. After half a quarter of an hour of repeated weighing, he retreated silently and retreated far away. He suddenly released his hidden state and moved forward slowly with a very careful pace.

Relieving the hidden shadow, even if there is the suppression of the turbid air, Yun Che's aura was instantly discovered by the three kings of the realms, and a powerful voice came from the depths: "Who is it!"

"Soul Realm? It's amazing... either die or get out!"

Three powerful pressure forces firmly locked Yun Che. Yun Che took a breath, accelerated his pace, passed through layers of turbid air, and quickly came to the front of the three kings of the realm.

When they saw Yun Che, the three of them were stunned: "It's you?"

"How did you come in? Isn't there anyone guarding the entrance?" Han Kuan said in a deep voice. The elders of the three major star realms guarding the entrance. Of course, they would not believe that Yun Che, who is in the mysterious power of the soul realm, will have the ability to force himself into.

Yun Che looked full of panic and said quickly: "I was looking for opportunities in the ancient realm, but I was accidentally involved in a space mysterious formation, and then I arrived here. I didn't expect it to be the underground palace where three kings of the realm entered. It was definitely not... I was interested in breaking in."

"Space Profound Array?" The three kings of the realms were still full of suspicion, but they were not completely unbelievable, because it was impossible for them to break in from the entrance. Emperor Nan Lie sneered: "I remember, you are called... Lingyun, right? The space Profound Array is accidentally entered? Haha, is it?"

But Mu Baimei raised her hand: "It is indeed very likely. There are countless secrets in the ancient realm, just like the sealing mysterious formation at the entrance of the underground palace. We didn't discover it until yesterday. Ling Yun, since you have entered it by mistake, then you should go up and return to the entrance. When you go out, you will report the name of my king, and no one will make things difficult for you."

"Then get out of here." Emperor Nan Lie stopped looking at him.

Yun Che did not turn around and leave as they thought, and raised his head and said, "Three Lords of Realm Kings, when I came here just now, I accidentally heard that you seemed to be blocked by poisonous fog and could not go deep into the underground palace. Is this dark green poisonous fog?"

Mu Baimei glanced at him: "No, but it has nothing to do with you, leave quickly."

"If it were just this poisonous fog, I would have a way to dispel them." Yun Che said.

His words undoubtedly made the Three Realms King look at each other at the same time. Emperor Nan Lie laughed: "It's up to you? Hahahaha!"

Mu Baimei shook her head and said seriously: "Little brother, if you can say this, maybe you have some achievements in poison art. But this is definitely not an ordinary poison, otherwise it would not stump the three of us."

"How about the younger generation bet with the three realm kings?"

"Oh?" Mu Baimei's eyebrows moved, showing a smile but rather interested expression.

Yun Che raised his hand and pointed to the faint green poisonous fog that was slowly floating like a wandering soul in front of him: "If I can dispel this poisonous fog and allow the three kings of the Realm to enter the underground palace, then please allow me to follow you into the underground palace and search for the imperial fairy grass together, how about it?"

He had the Heavenly Poison Beads on his body, and it was easy to pass through this poisonous fog area or dispel them.

With no detour, the three kings of the realm are blocked by poisonous fog, which is undoubtedly an opportunity for Yun Che. However, although he is not afraid of poisonous fog, he wants to break in from the three kings of the realm, which is undoubtedly a search for death. He thought of showing up in the same way, relaxing their vigilance, and then finding a reason such as sacrificing himself to test the depth of the poisonous fog for them, and then entering the underground palace alone... But doing so easily leads to suspicion and wariness. As long as his breath is about to escape from their spiritual sense in the poisonous fog, anyone who takes action will surely die.

After all, these three people are the kings of the world and are definitely not fools.

In the end, he chose this kind of "common benefits", which would arouse their vigilance and suspicion, but would not arouse their murderous intentions.

"Hahahaha!" Emperor Nan Lie glanced at him, laughing with disdain on his face, and mocking and contempt in his eyes: "A mere junior in the Soul Realm actually dreams of getting involved in the imperial fairy grass with us? Old Man Mu, your life-saving benefactor is not only ignorant and arrogant, but also an ambitious toad, hahaha."

Han Kuan also snorted coldly, his face full of disbelief and disdain.

"Old thief Nan Lie, don't say too early." Mu Baimei snorted lightly, but when facing Yun Che, his face was solemn and had no intention of ridicule: "Lingyun, this poisonous fog is extremely powerful, and it is not easy to disperse it. If you can really do it, it will be a big help to us. Of course, you are qualified to enter the underground palace together. I have no objection, and they will not have any objections."

"Hmph, what if he can't do it?" Emperor Nan Lie sneered.

"So what if you can't do it?" Mu Baimei said sarcastically: "If you can do it, it's God's help. If you can't do it, you won't lose any hair. You are really getting back to life."

Emperor Nan Lie sank his eyebrows and said with a smile: "Old man Mu is Old man Mu, tsk tsk tsk."

This sentence is meaningful, but he didn't say it any more.

Yun Che showed gratitude and said, "Thank you for your three kings to fulfill your wishes. I will not let you down if I have confidence. However, if I succeed, enter the underground palace together, and then find the Imperial Grass first..."

"Haha, that's yours." Out of Yun Che's expectations, before he finished speaking, Mu Baimei agreed with a smile: "Before entering the underground palace, the three of us had an agreement. Whoever finds the imperial fairy grass first will belong to it, and we must not force it. If you can really dispel the poisonous fog and allow us to enter the underground palace, of course, that's the same. After all, I don't want to be the traitor, and these two people probably don't want to be the shameless villain."

"It seems that Old Man Mu really believes that this kid can dispel the poisonous fog, and that king will be very eye-opener." Emperor Nan Lie smiled slightly and didn't laugh. He didn't believe Yun Che's words from beginning to end.

"Okay... Of course I don't dare to doubt the three kings of the realm." Yun Che nodded, then stopped talking, walked through the three of them, stood in front of the poisonous fog, slowly raised his left hand, and grabbed a mysterious stone with green light in his hand.

The Xuanshi was half the size of a fist, sparkling green, releasing a rather pure but not strong aura. Emperor Nan Lie sneered: "Just this? Hehehe, it's a huge smile..."

The contemptuous voice suddenly came to an abrupt end.
