Possessed by my father, I was reborn and became the supreme ruler.

Look at you, your lifespan is almost over, and you've even turned on your own son. Just because your flesh and blood are connected to you, he's become your sacrifice! Even tigers don't eat their cubs, you're worse than an animal!

Fortunately, Situ Jiuxiao had one problem that he had always been concerned about, because another essential condition for possession was also very important: the soul of the person being possessed must be under the control of the spellcaster.

Therefore, after practicing a cultivation technique, it is very important to be able to maintain the strength of one's soul!

Unaware of Ye Yunjian's thoughts, Situ Jiuxiao closed his eyes and continued, "This Nine Netherworld Profound Fire is said to have been transformed from the Netherworld Hell. It is the supreme Netherworld Fire in the Three Realms, the life fire born from the dead. Wherever its flames reach, it can cure all injuries and poisons."

Once the Nine Netherworld Fire is ignited, the earth fire in the endless abyss dissipates, transforming into nourishment for its growth.

Now concentrate on what I am about to teach you. I have a mantra to pass on, and you must remember it well: "Mysterious Qi generates fire, the mind follows the Qi, fire generates spirit, when Yang is at its peak, Yin diminishes..."

Ye Yunjian memorized the entire mental cultivation method from beginning to end, as taught by Situ Jiuxiao, and practiced it. Sure enough, it was almost identical to what he had practiced in his previous life.

However, this time Ye Yunjian was more cautious after making a note of it.

Before passing on the cultivation technique to him in his previous life, Situ Jiuxiao mentioned in a casual conversation that the technique was originally engraved on a black jade slip. However, after practicing the technique, heavenly thunder and earthly fire descended, and the jade slip was burned to only a fragment.

It is said that although it was just a fragment, neither his master nor he paid much attention to it at the time. However, later, during his final seclusion to break through to the Xuanhuang realm, Ye Yunjian realized that this original fragment actually contained supreme mysteries, and if he could unravel its secrets, he would benefit immensely.

He thought for a moment and then asked, "Master, you mentioned before that the original jade slip inscribed with this cultivation technique only has a fragment left?"

Situ Jiuxiao was already somewhat tired, and nodded, saying, "That's right, let's wait a moment."

He gently raised his right hand, revealing the black ring on his ring finger.

With a flick of his finger, light shot out from the Xuan Ring, and then a broken fragment of a black jade slip appeared in Situ Jiuxiao's hand.

Yao Situ Jiuxiao tapped his finger on the broken black fragment and let out a soft sigh.

Ye Yunjian immediately knelt down: "This disciple has a request that I cannot make."

"Jian'er, tell me." Situ Jiuxiao originally just wanted to take it out and show it to Ye Yunjian, but now he suddenly felt a little regretful.

"Disciple wishes to request Master to bestow this jade piece upon disciple!" Ye Yunjian said neither humbly nor arrogantly.

Situ Jiuxiao initially wanted to decline, but then he thought that he had had this jade piece for quite some time. After the jade slip was destroyed, he originally wanted to find some secret in it, but after exhausting all methods, he found that it was just an ordinary jade piece.

Since the cultivation technique has been passed on to Ye Yunjian, there's no point in keeping this jade piece with me. I might as well do him a favor and give it to him.

After hesitating for a moment, Situ Jiuxiao laughed and flicked his fingers, causing the black jade piece to fly up and fall into Ye Yunjian's palm.

"Fine, I'll leave it to you as a souvenir! Hahaha!"

After speaking, Situ Jiuxiao moved his sleeves slightly, and the originally closed door opened. Ye Yunjian put away the jade piece, bowed respectfully again, and backed out of "Junzixuan".

As the gate slowly closed again, Ye Yunjian glanced at the carved wooden windows outside the cave and the plaque with the three characters "Junzixuan" on the gate, then turned and strode towards his Spirit Fire Cave.

As he was leaving, he heard Situ Jiuxiao's voice transmission in his ear:

Jian'er, you are currently in the stage of opening your Xuan Meridians after restarting your cultivation. If you want to restore your Xuan Core, you will need more time and cultivation!

I will still arrange for the maid to deliver your medicine every day. Remember to take your medicine on time!

I'm waiting for your good news!

It was already dusk when they returned to the Spirit Fire Cave. They hadn't expected that this cultivation trip would take a whole day.

Ye Yunjian didn't say much and went straight to his usual meditation spot, where he practiced his earth fire meditation.

With a slight twitch of his fingers, he put the jade slip fragment into his pocket and then activated the mechanism for the Earth Fire Meditation.

The ground fire suddenly enveloped the meditation area, forming a small, enclosed cultivation space.

This underground fire is said to be closely related to the Nine Netherworlds and can help him cultivate.

Once inside this space, he was completely isolated from the world. Ye Yunjian then slowly closed his eyes and began to formally begin his cultivation.

As Ye Yunjian entered a state of renewed cultivation, the surrounding earth fire energy fluctuated slightly, transforming into wisps of slender spiritual energy that gathered into layers of dark fire patterns that slowly enveloped him.

Then, a spiritual cocoon formed by the dark spiritual energy merged into Ye Yunjian's body.

Speaking of which, this Nine Nether Profound Fire Technique is indeed far superior to the techniques he had practiced before. Ye Yunjian's originally shattered dantian gradually began to gather spiritual energy again, and it seemed to be slowly starting to reconnect.

As the dark spiritual energy continuously poured into Ye Yunjian's body, it flowed rapidly along his meridians. As the meridians continued to undulate, the dark spiritual energy was gradually absorbed by the meridians throughout his body, while the energy released during the absorption process was expelled from his body.

After the spiritual energy has circulated along the complex meridians for one cycle, it has become increasingly pure.

The earth fire beneath Ye Yun's sword became a furnace, and soon streams of spiritual energy began to condense and shrink beneath his original dantian.

After another three incense sticks' worth of time, the spiritual energy began to dissipate, turning into drops of dark liquid that formed small, constantly rotating vortexes.

Outside the cave, the sky turned from dusk to darkness.

Ye Yunjian's cultivation had almost reached a state of selflessness, and the earth fire became increasingly fierce.

Suddenly, he felt something in his chest being pulled by some force, and then it flew out.

The earth seemed to tremble, and in an instant, the subterranean fire seemed to suddenly go out, but it reformed into a spiritual cocoon three feet away from him, as if something unusual had happened underground.

"What's going on?" Ye Yunjian opened his eyes, only to find himself surrounded by darkness.

Next, flames slowly rose from the ground where the meditation was taking place, and then, as if breathing, the flames began to flicker on and off.

"Hahaha, I never thought I'd see the light of day again!"

Just as Ye Yunjian was filled with doubt and surprise, an old man's voice of wild joy suddenly came from underground.

With a change in expression, Ye Yunjian stood up and stood to the side of the earth fire.

The subterranean fire dimmed briefly, then erupted from even deeper within, burning fiercely once more…

"Haha, I scared you, I'm right here."

Just when Ye Yunjian thought he was hallucinating, the loud laughter appeared around him again.

Ye Yunjian narrowed his eyes and focused his gaze on the fragment of the black jade slip in front of him.

"Who are you?" Despite his extensive experience, Ye Yunjian remained on high alert, his voice trembling with nervousness.
