"A cultivator can actually cultivate the yin energy of the underworld. If you don't meet the deity, you can be called the yin energy in this immortal cultivation world. Even if other transcendents are in the lower world, you can't do anything to you. Unfortunately, I am the only creature in the world who is not afraid of the yin energy of the underworld. When I meet me, I will blame you for being too lucky." The old turtle's soul expanded and transformed into three feet. His momentum was vigorous, and it was several times stronger than just now.

Ye Yunxiao's momentum also increased, not weaker than the old turtle at all. A large piece of black mist suddenly radiated from his body, covering a three-meter-long space, occupying a small half of the altar.

Although the old turtle is in a state of soul, it can still mobilize the spiritual power of the physical body. His soul expands and relies on the spiritual power of the physical body to achieve it. If it is too far away from the physical body, even if he is a transcendent, he can only use soul attacks, and cannot use magic or physical attacks.

Half of the altar was shrouded in black fog, and Ye Yunxiao could no longer be seen. This black fog was the yin energy of the underworld and had the ability to isolate the spiritual consciousness. Ye Fei could not see the father's situation clearly with his naked eyes on the dark river, so he could only spread his perception and pay attention to the father's situation.

The old turtle's soul continued to expand and enlarge. In just a moment, his soul doubled again, and his aura also doubled, completely suppressing Ye Yunxiao's aura.

"Fellow Daoist, I'll lend you your body." The old turtle pounced on Ye Yunxiao, covered in black fog. His soul was more than twice as big as the black fog, and he wrapped all the black fog from outside to inside.

Ye Fei closely monitored his father's condition. He had taken out the Seven-Star Soul Refining Cauldron and held it in his hand, ready to throw out the Big Cauldron and sneak attack the old turtle at any time.

"Ah!" A shrill scream echoed throughout the underground space, and the old turtle's soul continued to twist and began to grow smaller quickly.

"That's just that!" Ye Yunxiao's voice was extremely cold, and a bone-thrusting chill could be heard from the sound alone.

"What did you do?" Old Turtle screamed in horror. He struggled to escape, but he seemed to be sucked by a powerful magnet. No matter how hard he struggled, it didn't work at all.

"The Yin Qi in the Underworld is ineffective against you, so what about the Spirit-Swallowing Technique?" The black mist around Ye Yunxiao slowly dissipated. His right hand was still pressed on the turtle shell, and his left hand was slightly raised, pressing against the head of the old turtle's soul.

The continuous source of soul energy was swallowed and absorbed by Ye Yunxiao. The spirit-swalking technique was originally the soul nemesis. As a transcendent, the old turtle had the spiritual consciousness of the Kaitian Realm, but his physical vitality was swallowed up by Ye Yunxiao from the beginning. At this moment, there was no contact with the physical spiritual power, and he could no longer get rid of Ye Yunxiao's palm.

"Give me your life, fellow Taoist, please spare me, I, oh, no, the old turtle is willing to surrender, willing to surrender." In less than ten breaths, the old turtle's soul disappeared by one third, which made him extremely frightened. He never thought that he would die, never thought.

Those who transcend have long been transcended by life and death, but they just say that they can have a long life without any accidents, but they don’t mean that they will not die.

If the sea of ​​consciousness is damaged and the soul cannot stay, strictly speaking, even if it dies, it can still be led to the underworld after death and continue to exist in the world.

But if the soul is destroyed, even if it is completely dead, this is also the reason why the old turtle is frightened and begged for mercy. He has only realized that the strong sense of crisis he felt from Ye Yunxiao before was simply from the spirit-swallowing technique, not the yin energy of the underworld.

"You have given the opportunity, now begging for mercy? It's too late!" Ye Yunxiao's eyes were still blood-red, but it was much better than just now, and it no longer seemed so terrifying.

"No, no, you can't kill me. If you kill me, no one will guard the passage of the underworld, it will bring great disasters to the entire immortal world. You can't kill me." The old turtle's soul gradually shrank, swallowing up most of the old turtle's soul energy, and Ye Yunxiao's eyes gradually became clear.

Ye Yunxiao ignored the old turtle. He had already swallowed the old turtle's vitality just now. Even if he let the old turtle go, he could not continue to survive in the world. He could only choose to go to the underworld to become a true spirit. However, the old turtle was still unaware of this and kept begging for mercy.

Half the incense stick in the front and back, the old turtle's soul was completely swallowed by Ye Yunxiao. He had sucked the vitality of the old turtle's body before, which was also the reason why he entered a devilish state.

He devoured the old turtle's soul, and made his physical strength and soul strength temporarily balance, and then pulled him back from his devilish state.

This is because with Ye Fei beside him, his willpower became particularly powerful, forcibly suppressing the restless energy in his body.

A transcendent person was completely swallowed by him, even his vitality and soul, making it difficult for him to suppress him, and he was about to enter the realm of the Immortal Calamity.

Breaking through the Immortal Tribulation is nothing to him. His body and soul have long been merged into one, and he has touched the space that only those who transcend can understand.

As long as there is enough Yin Qi in the Underworld, his realm can be broken through all the time. It is not difficult to become a transcendent directly. With enough Yin Qi in the Underworld, he will no longer be in danger of becoming a demon.

Ye Fei's perception has been paying attention to his father. Seeing that his father's breath changes, he stepped onto the altar and quickly walked to Ye Yunxiao and asked with concern: "Dad, how are you?"

"It's okay, it's just about to break through. Son, you go and get some top-quality spirit stones and go back first. I'm going to retreat here and go back at most half a year." Ye Yunxiao did not speak to Ye Fei, but used spiritual communication, and his voice rang out directly in Ye Fei's sea of ​​consciousness.

Without seeing any movements from him, he had already been cross-legged in the black fog vortex without warning, his body appeared and disappeared, and golden and yellow lights continued to flow alternately on his body.

"Dad, there is a Juetian Formation here. If Dad breaks through to the Tribulation Immortal, can he still go out?" Ye Fei asked with some concern.

Ye Yunxiao did not answer his words. He had no time anymore. After saying something to Ye Fei, he immediately entered the underworld channel and began to break through. In this moment, he had already entered the stage of forgetting both things and me.

Ye Fei did not get the answer, and he protected him for another day before he began to explore the underground space.

The old turtle said that half of the spirit stones in the entire immortal world gathered here, but these spirit stones are just raw stones and need to be excavated. If he wants to mine alone, he will not gain much if he is exhausted.

He was not paying attention to ordinary spirit stones, mainly because he wanted to find the best spirit stones and spirit veins.

Perception cannot detect spirit stones without life breath, so they can only use their spiritual sense to explore. His spiritual sense is in the vast ocean realm, and the exploration distance is far greater than perception. Even if they go deep into the cliff, the exploration depth can reach 200 meters.

If he didn't know if he didn't check it, he was startled. After his spiritual exploration, he found that even if it was a cliff and underground two hundred meters deep, it was all composed of spirit stones. There were several places where the energy was particularly powerful, and that should be the best spirit stones.

As for the spirit vein elves, they did not find it. However, even the top-grade spirit stones are mostly below 100 meters. If you want to get them, you have to dig them all the time. Ye Fei had no intention of becoming a miner and had to give up those top-grade spirit stones for the time being.
