After hesitating for a moment, Qin Xuan decided to continue digging deeper and completely eradicate the source of the Yin energy.

Because as long as the source exists, the yin energy here will be produced continuously.

After a period of time, it is also possible that there will be a sudden explosion due to excessive accumulation.

By that time, there will be excess yin energy and it will be difficult to eliminate the source.

So instead of letting it explode on its own, it is better to eliminate it directly before it accumulates!

Just do it.

Qin Xuan picked up the digging tools left behind by the workers and began to dig down bit by bit.

However, although it was purely manual excavation, with Qin Xuan's current ability, the excavation was no slower than those large machines.

Before long, the ground beneath his feet was three or four meters deep.

"The yin energy is getting heavier. It seems that I am looking in the right direction!"

"Wait, what's going on?"

After digging about five meters, Qin Xuan found that the ground under his feet suddenly became hard.

He dug down twice with great force and discovered that what he had dug out was not rock, but a huge man-made stone slab.

hack!

Click!

As Qin Xuan dug hard, the rock slab broke.

Qin Xuan pushed the stone slab over with all his strength, and a huge space suddenly appeared under his feet!

The moment the space was exposed to the outside, a yin energy that was almost turned into liquid suddenly rushed up into the sky from the hole!

A large dark cloud formed in the sky, covering the area.

"It's the Gathering Yin Formation!"

"God is helping me!"

Unexpectedly, an extremely excited old voice sounded from Qin Xuan's arms.

He took out everything in his arms, and sure enough, he saw an illusory figure of an old man appear on the gray stone ring.

"Who are you?"

"It was you who made that sound just now at Lin Mu's house?"

Looking at the old man in front of him, Qin Xuan was very cautious.

Just before rescuing Lin Qiaoqiao, he vaguely heard the word "Xuanyin Body".

He thought that there were too many voices around him and he was hallucinating.

Now it seems that the voice at that time was made by the old man in front of him.

"Haha, you're right."

"That voice at that time was also mine."

Now that he had spoken out in public, the old man had no intention of hiding it any longer.

The gray stone ring floated up gently, and his figure gradually enlarged and became life-size.

"I am Chen Xuan, the True Martial Dao Master. I died in a battle with someone and my remaining soul is here."

"The purpose is to find a talented person and train him one day."

"Fortunately, after you have mastered your training, you can help me kill my enemies!"

"It is obvious that you are the one I chose. The body-refining technique you are practicing now and the magical weapon in your hand are all created by me."

The old man stroked his white beard, his eyes shining.

Qin Xuan was skeptical and did not intend to believe the other party's one-sided words.

After all, I am not the protagonist of the so-called immortal cultivation novel, and it is even more impossible for me to just get a ring and get a golden finger.

So even though the other party looked friendly, he still didn't take it lightly.

"Haha, little guy, you don't have to be so vigilant."

"Now I am only a remnant of my soul. I don't have enough soul power to nourish myself, so I can't interfere with the things around you at all."

"If it weren't for the appearance of the Xuanyin Body and the Gathering Yin Formation, I would never have wasted my soul power to show up."

While Qin Xuan was looking at Chen Xuan, Chen Xuan was also looking Qin Xuan up and down.

He was right. He was already extremely weak now.

If it weren't for the fact that this Yin Gathering Array had gathered enough soul power to allow him to replenish himself, he would not have wasted his limited soul power to show up.

So what he wanted to do most now was to throw himself into the Yin Gathering Array and absorb all the soul power in it.

But it was obvious that Qin Xuan would not let him do so.

"I don't know how much of what you just said is true and how much is false."

"But if you don't want to be annihilated, please stay away from that formation!"

Looking at the old man gradually floating towards the formation, Qin Xuan's hands suddenly emitted a hint of white light.

This was the thunder magic taught to him by Ke Wudi. Not only was its attack swift, as fast as light, but it was also extremely strong and masculine, and was specifically designed to defeat all evil spirits.

Feeling the Taoist magic in Qin Xuan's hands, the old man's expression changed.

In his current state, let alone the thunder magic, even if he is hit by the simplest attack magic, his soul will be destroyed!

"Don't panic little guy!"

"I will listen to you."

Floating back angrily, Chen Xuan continued, "Little guy, my soul power is almost gone now."

"If you don't let me absorb the Yin energy in the formation, I might only be able to hold on for a few more minutes before I become silent again."

"Since your goal is to get rid of the source of the Yin energy here, why not do a good deed and let me absorb it!"

"Don't worry, what I said is true."

"As long as I absorb this Yin energy and recover some strength, I can accept you as my disciple and guide you to become the most powerful being in the Cangming world!"

"You have already practiced this physical training chapter, so you should be able to feel my ability!"

"Don't you want to advance quickly and continue practicing the techniques after the Body Refining Chapter?!"

Chen Xuan's words really touched Qin Xuan's heart.

Of course he felt the power of the Body Refining Chapter.

After just a few days of practice, one can become as strong as a martial arts master.

After practicing for more than a month, he even reached the level of Grand Master.

Now, he has only practiced the fourth move.

In terms of physique alone, he is comparable to the long-established grandmasters.

Not to mention that his third master, who was renowned for his magic, had only reached the same level of cultivation as him.

"Okay, it's not impossible to let you absorb the Yin energy."

"But you must prove that you will not act recklessly after absorbing the Yin energy."

After pondering for a moment, Qin Xuan still agreed that Chen Xuan could rely on Yin Qi to nourish his soul.

Firstly, Qin Xuan was very curious about the other party's origin and story.

Secondly, it is naturally out of the desire for martial arts.

After all, who doesn't want to become stronger if possible?

Seeing that Qin Xuan's seal on his mouth had loosened, Chen Xuan was also very happy.

Without hesitation, he stretched out his right hand and drew a strange symbol in the air.

Then the sky changed drastically, and rumbling thunder suddenly appeared in the air and lingered for a long time.

"Don't worry, I will swear a great oath to heaven and earth right now. If I break this oath, you don't need to do anything, the will of the great way of this world will directly wipe me out!"

"Then you don't have to worry anymore, right?"

"That's best."

Feeling the vague pressure from heaven and earth, and seeing with one's own eyes the oath that the other party swore to heaven and earth.

Qin Xuan reluctantly believed what the other party said.

He put away the Taoist magic in his hand and stood with his hands behind his back, waiting for Chen Xuan to go into the formation and absorb the negative energy from it.

But just as Chen Xuan was about to reach the center of the formation on the stone ring, the yin energy that had just gathered in the sky suddenly fluctuated.

As the wind dissipated, a figure fell from the sky.

"What a bastard! Who dares to touch the formation of the Hundred Ghost Emperor?!"
