Chapter 437 Hidden Underground Floor 10, the Mysterious 'Prison Gate'

This stone gate is about a hundred feet high and dozens of feet wide.

The two huge black stones that were tightly closed glowed with a strange light, and there were five very eye-catching huge grooves on them.

The grooves are closely arranged, and they are all carved with simple lines, revealing an indescribable weirdness.

Yang Che released his spiritual consciousness and found that it could not penetrate this door at all.

After pondering for a moment, he jumped directly onto the wide back of the Caiyi Bird and ordered the Caiyi Bird to fly towards the huge and weird stone door.

Come closer and look carefully.

When he discovered that there was a small groove in each of the five huge grooves, Yang Che's heart suddenly moved, and his eyes were extremely surprised.

Because these five small grooves are actually heart-shaped grooves the size of a fist.

"Heart-shaped, fist-sized..."

Yang Che almost immediately thought of the five-planet soul crystal he had obtained.

Taking out the 'Zhenxing' and 'Yinghuo', Yang Che carefully compared the heart-shaped grooves and immediately confirmed that if the five-planet soul crystal was put in, it would be neither too big nor too small, just right.

Yang Che put the five-planet soul crystals away again and did not put them into the heart-shaped groove rashly.

After all, there are obviously five grooves on this stone door, which are used to place five five-planet soul crystals.

If only two pieces were put in rashly, something unexpected would happen and the two five-planet soul crystals would be wasted, which would be very bad.

Yang Che stood on the back of the huge colorful bird, thought for a moment, and suddenly fired his spiritual power on the huge stone door.

However, the stone door remained motionless, nothing unusual.

Yang Che tried to attack again and again, but found that the stone door was extremely hard, not an extraordinary object, and it was really difficult to shake.

"It seems that we must obtain all the five-planet soul crystals before we can open this door."

He murmured to himself, suddenly remembering his master's instructions, and couldn't help but guess in his heart that master Zhang Sheng should have known about the existence of this sect a long time ago, so he must obtain the five-planet soul crystal.

Master once said that these five planet soul crystals are related to his future cultivation path. Could it be that this door leads to the upper world?

Then he thought about the black jade slip he got from Taoist Ziye's cave, which guided him to the Netherworld Gate and entered the Nine Nether Purgatory.

I'm afraid that the so-called 'secret of entering the upper world' refers to the stone gate in front of you.

When he thought of this, Yang Che was so excited that he couldn't keep calm, so he directly entered the phantom magic stone space and asked the hell phoenix for advice.

"What? Did you really discover this door?"

After listening to Yang Che's description, Feng Jinyun transformed into a beautiful middle-aged woman, and a look of disbelief suddenly appeared in her illusive phoenix eyes.

Yang Che simply didn't want to talk nonsense. With a thought, he and Feng Jinyun both appeared in front of the huge stone door.

"Senior Youfeng, do you know this sect?"

Seeing the look of surprise and excitement on Hell Youfeng's face, Yang Che immediately asked.

Feng Jinyun nodded slightly and said: "Although I have not seen this gate with my own eyes, it is the same as what is recorded in the clan's secret book. This gate should be the legendary 'Prison Gate'."

"Through the prison gate?" Yang Che's eyes showed confusion.

"Yes. The Hell Gate is the gateway from the Nine Nether Purgatory to the spiritual world, the Nine Nether Realm and the Infinite Hell. Although the Infinite Hell is a special prison in the Nine Nether Realm where lawless monks are imprisoned, when you reach the Infinite Hell, It’s like entering the spiritual world, the real upper world.”

Yang Che's heart trembled when he heard this. It seemed that the Golden Dragon King Ruitian was right. He said that the world behind the Netherworld Gate leads to a very terrifying prison.

He asked with worry in his eyes: "Senior Youfeng, if you enter the Eternal Hell through this door, wouldn't it mean that you are also imprisoned in it, which is very dangerous?"

Feng Jinyun said: "The Infinite Hell does have a bad reputation. But if you enter the Infinite Hell through this door in the future, don't worry. It is said that among the guards here are strong men from the Youfeng clan of Hell."

With that said, Hell Phoenix flew to the stone door, looked at it carefully and said:

"Opening this door requires five-planet soul crystals and a large number of high-grade spiritual stones. If you want to open this door, you must obtain five five-planet soul crystals and prepare at least three thousand high-grade spiritual stones."

When Yang Che heard this, he first felt a little headache because he needed so many high-grade spiritual stones, and then he suddenly had questions about his master.

Master is not a person from the upper world. How on earth did he know such a secret thing?

Thinking of what Master once said, when all five planetary soul crystals are collected, one will naturally understand the usefulness of these star soul crystals. It seems that if all five planetary soul crystals are obtained, there may be some hints.

Also, the five planet soul crystals are kept by the domain lords’ mansions of the five major realms of cultivating immortals in the human world. Do these ‘domain lords’ know that these star soul crystals are related to the ‘Prison Gate’?

Many questions made Yang Che fall into deep thought.

The hell ghost phoenix was still looking around carefully and walked in along the dim light passage.

After a while, Yang Che suddenly heard the voice of the hell phoenix coming from the dim light channel:

"Yang Che, come here quickly."

Yang Che quickly walked through the passage and came to the space barrier.

"The cracks in this space are very dense. How did you get through them?"

Feng Jinyun's eyes were full of doubts.

Yang Che thought, and the colorful bird appeared.

"I see."

Feng Jinyun understood it as soon as he saw Caiyi Bird.

Afterwards, both of them were wrapped in the colorful light of the Caiyi Bird, passed through the space barrier, and came to the circular cylindrical stone chamber.

The restriction was broken, and Yang Che and Feng Jinyun also successfully left the stone palace and returned to the mist-shrouded place.

After careful sensing, Feng Jinyun's illusory face showed an even more surprised look, and then slowly said:

"Yang Che, this should be the tenth underground level of Purgatory."

"The tenth underground floor? Isn't there only nine underground floors in purgatory?"

Yang Che asked out of confusion.

Feng Jinyun said: "The tenth underground floor should always be hidden under the ninth floor. There seems to be no entrance to this place on the ninth underground floor."

After saying that, she withdrew her consciousness, and Xuan Huan's face suddenly became extremely solemn.

And Yang Che suddenly thought of something, and immediately realized that it must be the use of the 'teleportation array' in the Phantom Cave on the ninth floor, which coincidentally teleported him to the tenth floor underground.

"Let's go back quickly. There is a very powerful being on the tenth floor underground. In the Yinluo Tower before, my soul power was consumed a lot. Now I am trying to protect my remaining soul, so I am afraid I am no match for her."

After Feng Jinyun finished speaking, Yang Che also knew that she must be talking about the woman with wings on her back, so without any hesitation, the two of them re-entered the stone hall, and walked through the stone hall wrapped in the colorful light of the Caiyi Bird. The space barrier returned to the dim light channel.

At this time, Feng Jinyun suddenly stopped, stared at Yang Che and said:

"I remember that your Nine Spirit Sword seems to be missing a demon spirit?"

As soon as these words came out, Cai Yiniao on the side suddenly couldn't help but shudder.

Yang Che didn't notice Cai Yiniao. After nodding, his eyes suddenly lit up: "Senior Youfeng, are you saying that the woman outside is..."

"Yes. This woman is an extremely powerful demon spirit, and her body is the extremely rare 'Netherworld Red Butterfly'."
