"Boy, have you met my request?" The old turtle's lazy voice came into the ears of the two.

"If you haven't achieved it, then you dare to alarm senior." Ye Fei threw out a stone that had been prepared long ago, and the sword wisely ran. A spiritual power hit the stone accurately. With a pop, the stone turned into powder and drifted in the air.

"The spiritual power is so pure. How did you do it?" Lao Guiyu asked in surprise.

"The skills I practiced before are quite special. They can compress spiritual power and improve the purity of spiritual power." Ye Fei replied half-truely.

"You humans can really create miracles with such magical skills." Lao Gui paused and continued, "Since you have met the requirements, then go to the third level to get the subsequent skills. But remember, if you practice the ninth level behind the Badao Jue, even if you are the successor of Badao Sect, you have to carry the burden of rebuilding Badao Sect."

"Senior Turtle, I also want to rebuild the Badao Gate, but this place is not suitable for the mountain gate of the Badao Gate now. Can I rebuild the mountain gate outside?" Ye Fei was waiting for the old turtle to say this and asked with the flow.

"Change the place to re-establish the mountain gate?" Lao Gui said and then became silent.

Ye Fei stood up quietly and waited. He didn't know what Lao Gui was thinking. He had his own mind. Since he wanted to re-establish the Badao Sect, he would definitely take away all the resources here, and the spiritual veins would be obtained naturally.

"There is a spiritual medicine treasure critic in the third row of the bookshelf by the south wall, number 147. You went over to activate the spiritual power of the Badao Gate to push the book inward with one finger." The old turtle's voice sounded again.

Ye Fei didn't ask much, walked to the south wall, followed the number to find the spiritual medicine treasure appraisal, and did what the old turtle said.

The south wall separates from both sides, and a two-meter-wide lower entrance appears in front of you.

"Come in." The old turtle's voice was no longer ethereal and came from below.

Ye Fei and Ye Ling entered the entrance one after another without hesitation.

Pearls are inlaid on both sides of the passage, and the light flows, emitting a faint purple light.

The passage stairs are about a hundred steps, and the passage is a huge underground river. The cliff walls on both sides of the river are shining with crystal light.

The spiritual power here is several times stronger than the one above, and Ye Fei and Ye Ling stood by the river with their eyes straightened.

Everything in front of me was really shocking. Those crystal light spots were not pearls, but spirit stones. Even though Ye Fei was mentally prepared and knew that there was a huge spiritual vein here, he was still shocked when he saw it.

"Come here, walk all the way to the head." The old turtle's voice came again.

Moving forward along the sound, Ye Fei and Ye Ling gradually felt a yin and cold air coming towards him. The further forward, the more intense the yin and cold air, the more dense the light spots on the cliffs on both sides.

After walking for about a hundred feet, I finally reached the end. A huge altar appeared in front of me. There was a whirlpool formed by black mist in the middle, which kept rotating, looking a bit like a portal.

The altar is connected to sixteen purple-gold chains, and eight at the ends of the chain are connected to both sides of the cliff.

"Senior Turtle, where are you?" Ye Fei's eyes turned around, and he didn't see the old turtle's body, so he asked.

The altar suddenly moved, sixteen purple-gold chains were suddenly straightened, and a huge head floated out of the underworld.

When he completely surfaced, Ye Fei saw clearly that this was a huge turtle, with an altar built on his back and sixteen purple-gold chains worn on his shell. This scene was completely different from what Ye Fei imagined.

He originally wanted to fool the old turtle, but in this situation, how can he fool him?

At the same time, he was alert in his heart. Seeing this, the old turtle was clearly imprisoned here. Since he was imprisoned, it was impossible to be a sect-protecting beast.

The black fog vortex on his back is the source of the yin and cold energy. When it approaches here, the yin and cold energy can even penetrate the bone marrow, making people extremely uncomfortable.

"Senior, this is this?" Ye Fei asked tentatively, and at the same time he was ready to escape at any time.

"Do you know what is on my back?" Lao Gui's tone was as lazy as before, without any hostility.

"I don't know." Although Ye Fei had a guess in his heart, he didn't say it, waiting for the old turtle to reveal it himself.

"This is the legendary channel connecting the underworld." Old Turtle's tone was normal, but Ye Fei and Ye Ling changed color at the same time. Although Ye Fei had guessed it in his heart, Old Turtle still surprised him by saying it himself.

"I wonder why this passage is on the back of my senior?" Ye Fei asked with a surprise in his heart.

"On the entire world of immortal cultivation, only my defense can withstand the erosion of the cold and cold energy of the underworld. No one except me can suppress this passage." The old turtle looked serene. He had been trapped here for more than 13,000 years. Although most of the time, he spent his sleep, he always spent his loneliness and loneliness whenever he woke up.

"Why should I suppress it? There is not only one channel between the Immortal Cultivation World and the Underworld. According to my younger generation, there are as many as dozens of channels connected to the Underworld." Ye Fei asked with confusion on his face.

"It's different. Other channels are connected in one direction, and only pure soul bodies can enter the underworld from the channel." The old turtle's tone was low. It might be very hard to float like this, and he slowly sank into the dark river again.

Although he sank into the dark river, his voice still clearly reached the ears of the two people: "Ten thousand thousand years ago, the underworld suddenly began to invade the Immortal Cultivation World for some reason. The spatial nodes here and the Underworld are the weakest. The Holy King uses the Yin Qi of the Underworld to continuously erode the Immortal Cultivation World. You can see the black fog above, which is the result of being eroded by the Yin Qi of the Underworld."

"The Black Mist Forest seems not suitable for the survival of the soul body. Once the soul form enters, it will gradually dissipate. The true spirit of the underworld is also a soul body. If it is the yin energy of the underworld, shouldn't it be suitable for the survival of the soul body?" Ye Fei took a few steps back. He became suspicious of the old turtle, and his heart was even more vigilant.

"That was to eliminate the army of true spirits in the underworld who ran to the cultivation world. The Heavenly Palace sprinkled soul-breaking smoke in the black fog, which led to the gradually dissipation of the soul body. The effective height of the soul-breaking smoke was only three meters. They set up a forbidden air array, which completely eliminated the army of the underworld who ran to the cultivation world." The old turtle explained.

"So that's it. Senior should belong to the fairy world." Ye Fei asked tentatively.

"Yes, I do come from the fairy world. Back then, the black fog continued to erode the fairy world, attracting the attention of the fairy world and the Heavenly Palace. After investigation, it was found that a large number of true spirits in the underworld appeared here. The underworld tried to use yin energy to cover the entire fairy world and turn the fairy world into a place suitable for the survival of true spirits in the underworld." Lao Turtle narrated in a plain tone.

Ye Fei did not interrupt, just listened quietly.

The old turtle continued: "Later, the Immortal World and the Heavenly Palace joined forces to set up the Great Array of the Sky here and blocked this passage. They were afraid that the passage would be broken again, so they found me, who had the strongest defense in the Immortal World, blocked the space passage on my back, and then concentrated half of the spiritual veins of the Immortal Cultivation World here to form a super-large spiritual vein, which was used as the source of my spiritual power."
