The fourth layer of the underworld, the land of the Void.

When Gu Chen came here this time, he immediately found that the Absolute Yin Land had changed differently from before.

"What about the resentful spirits, isn't it nothing, I still want to see what the resentful spirits look like!" Long Ranxi stared at a pair of big eyes that were spinning around, but he didn't see the resentful spirit that Gu Chen said, so he couldn't help but ask Gu Chen.

"Sect Master, is this really the Land of Absolute Yin? Didn't you say that the Yin Qi of the Land of Absolute Yin here is extremely heavy? How do I feel that it is even worse than the Land of Absolute Yin that I discovered in the eastern part of Yuezhou last time! That Land of Absolute Yin must have only existed for hundreds of years! The Land of Absolute Yin here is tens of thousands of years old, how can it be that the Yin Qi is so weak?" Gu Shisan also looked at Gu Chen with a puzzled expression and said.

"This seat is also deeply strange! The last time I arrived, there were obviously countless resentful spirits, how come this time not only are the resentful spirits gone, but even the yin qi seems to have weakened!" Gu Chen also looked puzzled.

"It should have been purified!Didn't Sect Leader Gu say that the people from the Donkey Kong Temple and the Bodhi Sect also came, and the Buddhism Sect still has a lot of experience in purifying evil things!" Li Xuan suddenly interjected.

Gu Chen thought for a moment and felt that it should be like this, although Ji Ruofeng couldn't purify the resentful spirits here last time, Ji Ming, Xuanchi, Xuanyi, and Xuanjing were all top masters of Buddhism, and the four of them were naturally more than a hundred times stronger than Ji Ruofeng's Buddha light.

Hei Wu suddenly frowned and said: "I think it's a little strange, purifying the resentful spirit purifies the resentful spirit, I have never heard that the Buddhism can also purify the yin qi! The yin qi is affected by the place of the absolute yin, and it is logically difficult to be changed by external forces!"

Gu Chen was thoughtful when he heard this, and then he suddenly realized.

Gu Chen touched his chin and said: "It should be the 'Absolute Yin Pearl' of the Absolute Yin Land that has been taken away, the Absolute Yin Pearl, it is a heavy treasure transformed by the essence of the Absolute Yin Land, if it leaves the Absolute Yin Land, the Yin Qi here will naturally be greatly weakened!"

"The Absolute Yin Pearl! This place has actually given birth to the Absolute Yin Pearl?" everyone's eyes lit up when they heard this, obviously knowing the role of the Absolute Yin Pearl.

Li Chengfeng couldn't help but ask Gu Chen curiously, "Sect Master Gu, then why didn't you take the Absolute Yin Bead away last time?"

Everyone also looked at Gu Chen with a puzzled expression.

Gu Chen couldn't help but show a wry smile, he didn't want to take away the Absolute Yin Bead last time, but Rong Qingya's girl resolutely resisted this matter, saying that the Absolute Yin Bead was the most evil thing, even if she saw it, she would destroy it, let alone take it away! Later, when Gu Chen returned, he was in a hurry to leave, so he didn't pay attention to the matter of the Absolute Yin Bead, but he didn't expect that when he came down again, the Absolute Yin Bead had already fallen into the hands of others.

"There is another secret in this matter, but it is useless to talk about it now!" Gu Chen spread his hands and said to everyone.

Seeing that Gu Chen was reluctant to elaborate, everyone was not reluctant.

"Then let's help Sister Feng'er find the 'Heart of the Heavenly Phoenix' first!" Long Ranxi said suddenly.

Gu Chen couldn't help but look at everyone when he heard this.

Everyone nodded at this, although it was Feng Rinwu's private matter to find the heart of Tianfeng, but Feng Rinwu's trip helped a lot, if it weren't for her, everyone would have already returned to the Nine Heavens, so everyone had no objection to this.

Seeing that everyone had no opinions, Gu Chen waved his hand and said, "Everyone come with me!"

Afterwards, Gu Chen led everyone towards the cave that was suspected to have the heart of the Heavenly Phoenix.

————————————————————————————————————————————————————————————————

In the blazing cavern, everyone curiously gathered around a cave that led to the ground.

The bottom was full of crimson liquid, and bubbles were tumbling from time to time, like hot lava.

"Feng'er, how do you feel, is there a Heavenly Phoenix Heart down here?" Gu Chen asked at Feng Rinwu, who was frowning beside him.

Feng Rin Wu said with some hesitation: "I'm not sure, I just feel that there seems to be something down here that has some connection with me, but this feeling is very faint, and it comes and goes! I don't even know its exact location!"

"Then what are your plans?" Gu Chen asked Feng Rin Wu again.

Feng Rinwu thought for a while and said, "I want to ...... Go down and have a look!"

"Let's go down and have a look?" everyone was stunned when they heard this.

Long Ranxi said to Feng Rin Wu with an anxious expression: "How can this be done? This is not a waterhole! Those liquids are extremely hot even if they are not magma, and the danger is unknown here, how can you take such a risk?"

Feng Rin Wu shook his head and said: "The phoenix is reborn from the fire, the general flame is not a threat to our Feng clan, even if it is magma, it is no different from Qing Qing to me!"

"Wait, don't worry!" Gu Chen grabbed Feng Rinwu's small hand and whispered to it.

Afterwards, Gu Chen asked Shen Yan, "Old Shen, can your eyes see through this?"

Shen Yan nodded, then shook his head again.

Seeing this, Long Ranxi couldn't help but say to Shen Yan with an irritated face: "If you can, if you can't, you can't, what do you mean by nodding and shaking your head?"

"Ran Xi, don't interrupt, Lao Shen will naturally explain!" Gu Chen waved his hand at Long Ranxi and said, then glanced at Shen Xi.

Shen Yan said to Gu Chen: "Sect Master, my subordinates have already used the Wisdom Eye to observe this place just now, and the reason why I nodded is because the Wisdom Eye can see through this layer of liquid, and I shook my head because there is a strange energy under the liquid, and the Wisdom Eye has been greatly affected, and I can't see the real situation clearly!"

"Then tell me first, what's so abnormal about these liquids, how deep is they?" Gu Chen asked Shen Yan.

Shen Yan replied: "Judging from the experience of his subordinates, these liquids should be blood! And they are a mixture of countless kinds of blood, and here is a pool of blood! The blood pool is about nearly 100 meters deep! The magical power under these blood seems to be repelling these bloods, forming a vacuum space. Anything further down and I won't be able to see it!"

When everyone heard this, their scalps were numb, and these liquids that looked like magma turned out to be blood? Countless kinds of blood were mixed into a pool of blood nearly 100 meters deep? How many people had to die, and how much blood had to be released?

Gu Shisan looked at Shen Yan with a puzzled expression and said, "Right Envoy Shen, you can't be mistaken, right? You said it's blood, then why didn't we smell blood?"

"Yes, I didn't smell anything! If it was blood, it wouldn't be able to escape my nose!" Long Ranxi said and twitched his nose, revealing a strange expression.

"I think, what Lao Shen said should be good!" Hei Wu suddenly interjected.

Hearing this, everyone couldn't help but cast their eyes on Hei Wu, waiting for his next step.

Hei Wu first glanced at the people of the Pantheistic Sect and said, "You should know the origin of the red abyss, right?"

Gu Chen, Tang Qingwu, Shen Yan, and Gu Shisan were all thoughtful, and the others were confused.

Gu Chen explained the confusion for everyone: "Chi Yuan is one of the overlords of the ancient period, living in one of the ancient forbidden places, in the 'Boundless Blood Sea', his strongest talent is to control the power of blood against the enemy, Hei Wu inherited the law of Chi Yuan, and his sensitivity to blood is naturally unparalleled in the world!"

"So, the left envoy has already determined, these are really blood?" Tang Qingwu asked at Hei Wu.

Hei Wu nodded and said: "Yes, but because of the time, I can't see what the specific blood is, these blood should have been specially treated, so there is no smell of blood, and it will not be evaporated by heat." ”

"Then who is going to build a blood pool here? Could it be that the Demon Gate Blood Dao Cultivator wants to use blood to improve his cultivation?" Li Xuan suddenly interjected.

"Elder Li Xuan is really well-informed, and this envoy also thinks so! This technique is very similar to the secret method of blood cultivation! First, place a treasure at the bottom of the blood pool, and then pour the blood into the blood pool step by step, use the treasure to purify the evil qi in the blood, and use the blood to absorb the energy in the treasure, and when the energy fills the entire blood pool, the evil qi in the blood is also completely purified, and then you can absorb the essence of the blood pool without any scruples to improve yourself!"

Gu Chen's heart jumped when he heard this, and he felt that there must be a shocking conspiracy in it!

Gu Chen looked at Hei Wu and asked, "Old Hei, can you tell how long this blood pool has existed?"

Hei Wu hesitated for a while when he heard this, and then said to Gu Chen, "Sect Master, wait a minute!"

Then, Hei Wu waved at the blood pool, and a series of blood beads flew into Hei Wu's palm.

Black Sycamore held the blood bead in his hand, his eyes closed.

After a few moments, Black Sycamore opened his eyes and sprinkled the blood beads into the pool of blood again.

Hei Wu said slowly to Gu Chen: "When the blood pool was built, the subordinates have no way of knowing, but they know that the energy in the blood pool was absorbed by someone one or two hundred years ago!"

"One or two hundred years ......" Gu Chen suddenly fell into thought.

"Could it be the last time the Xutian Secret Realm was opened?" Gu Chen said with his eyes suddenly widening.

"Is the sect leader suspicious, the last time the Secret Realm of the Ruins Heaven was opened, someone took this opportunity to hunt down the monks who came in to hunt for treasures and use their blood to practice?" asked Hei Wu at Gu Chen.

Gu Chen said with a solemn face: "It's very possible! According to the Sword Immortal, the mortality rate of the Xutian Secret Realm last time was more than half! But judging from the situation this time, the Xutian Secret Realm is not so dangerous! Therefore, they are likely to be calculated by someone with a heart!"

"This ...... But as far as the old man knows, among the people who came out alive from the Ruin Heaven Secret Realm last time, there were no Demon Sect monks!" Li Xuan suddenly interjected at this time.

"It's not surprising, maybe his plot was discovered and he was killed before he went out!" Gu Shisan said disapprerovingly.

"It's also possible that he didn't go out at all!" Long Ranxi suddenly interjected.

Gu Chen's heart suddenly flashed, and then his heart was shocked, Ran Xi was reasonable! If that person really didn't go out...... Yan Xiu: Could it be that all this was done by Yan Xiu?

This would explain why he was able to break through to the Holy Realm in the Secret Realm of the Ruined Heaven, where the aura was scarce!

The monks who could enter the Secret Realm of the Ruined Heaven were all the leaders of the various forces in the Tian Yuan Continent, their cultivation was profound, and their blood naturally contained great energy, and their blood cultivation was more than a hundred times faster than normal methods!

Immediately, Gu Chen thought of something even more amazing!

Gu Chen's expression and demeanor were very strange, when he saw Rong Qingya and Gu Chen before, it was like seeing strangers, and he didn't know anything about the current situation in the Tian Yuan Continent.

Originally, Gu Chen suspected that he had been taken away, but the method of taking away was the secret method of the Demon Gate, and it had been lost for a long time, and Yan Xiu was a master of Buddhism, so it stands to reason that he should not master this method, so Gu Chen denied the matter.

But at this time, knowing that this blood pool, and the energy that had been absorbed by someone when the Xutian Secret Realm was opened last time, Gu Chen couldn't help but doubt it again.

Although Yan Xiu is a member of the Buddhist Sect, it is not surprising that he has lived in the Xutian Secret Realm for so long, and he has obtained the Demon Gate Secret Method from the Demon Gate monks who came here!
