Under the soil, deep in the ground before the coffin.

With rat ears and rat tails, a demon who looks like an innocent child, an old child.

Silently standing in the place surrounded by the soil.

The old boy's green eyes were shining.

Now.

It gritted its teeth and spoke.

He said to himself, "You dare to kill my yin rat!" Bad self! …… It's really hateful!! ”

Its voice matches its appearance.

It was the voice of a six- or seven-year-old child.

But.

Such a bitter and angry child's voice echoed in front of the coffin deep underground at this time.

The voice was sharp and full of anger.

But it looks extremely eerie and terrifying!

After venting his resentful words, the old boy gradually suppressed the anger in his heart.

Anger won't solve anything!

You need to find a way to relieve the anger in your heart.

So, it slowly closed its eyes.

It seems to be sensing something.

That's right!

The old boy is sensing the enemy who killed the yin rat.

It wants to see.

That guy who can exterminate the yin rat that is hiding about fifty zhang deep underground, what kind of sacredness is it!

Since the yang rat was able to fall into death in time and avoid the disaster, it means that it had sensed something before it died.

It also shows that before the yang rat fakes his death, there must be enough time and arrangements.

At this moment, the old boy is the clue left before the yang rat was buried in the coffin!

Not close to or far from here, there is a deep mountain and old forest.

At this time.

At the entrance of a cave in the old forest of this deep mountain.

In a corner under the cover of weeds.

A stuffed thing, sneaking around.

It's a mouse!

Thieves, sneaky, sneaky rats.

It was the rat evil that Niu Yuanping didn't kill before!

Then.

In order not to startle the snake, so that the rat demon hidden in the depths of the earth will not perceive the danger and flee vigilantly.

Niu Yuanping did not immediately kill this rat demon.

Instead, the priority is to kill the rats deep underground.

However.

After dealing with the rats, Niu Yuanping found that the rat evil that had hidden under the pillow of his bed had disappeared!

I searched for a long time, but I couldn't find it.

In the end, I had to give up.

At that time, I was immersed in the joy of killing the demon of the rat.

Niu Yuanping no longer put a little mouse that ran away in his eyes.

I want to come in Niu Yuanping.

A rat demon without a backer, forgiving it won't be a big deal.

In the future, it will definitely be planted in the hands of some demon slayer.

Other than that.

Niu Yuanping found that after Shuo Rat died, Ma Quan, who pretended to be Qian Jiutong, died violently.

So it was determined that the Shuo Rat Demon Evil was the mastermind behind the group of Rat Evil and Ma Quan.

Since the operators behind the scenes are all dead, the rat evil that escaped must not live long.

It is likely that like Ma Quan, the final outcome is to hide in a cold and damp corner and kill himself!

Thereupon.

Niu Yuanping didn't completely forget about the existence of the rat evil.

But.

He would never have thought of it at the moment!

Not only did the horses not really die......

The mastermind behind the scenes is not a rat demon!

It's an old child!

In addition, he didn't expect that the rat evil that was released by himself had not died out.

Not only did it not die out.

At this moment, it has also become a tool used by the old children to lock and track themselves, and they are quietly chasing it!

After the death of the rat, he sensed that something bad was going to happen to the yang rat, and immediately asked the rat evil to remove the evil power from the body.

Only the ordinary vitality force is left, and the breath is completely hidden.

And gave it the only order.

Track Niu Yuanping!

Without the power of demons, the rat evil only retains the power of vitality.

It's not much different from ordinary rats.

So you won't be easily noticed!

Niu Yuanping naturally didn't notice that he was being followed.

Now.

The rat demon quietly pursued the cave deep in the forest.

It poked its head out and slipped into the cave.

In the depths of the cave.

On the top of a cobblestone, a figure sat cross-legged.

The rat demon slipped into a crevice in the stone not far from the cross-kneeled man, and quietly poked his head out, staring at the green rat's eyes, and secretly observed.

That's right.

In the cave, the cross-legged man on the top of the cobblestone is Niu Yuanping!

After absorbing all the energy in the body of the Squat Demon Demon, he was refining that energy into his own cultivation power at this time.

The energy is converging in the meridians of Niu Yuanping's soul and wandering!

In the process of wandering, the bioelectric energy of the Shuo Rat Demon began to transform into his soul power, and finally gathered in the soul dantian.

There, there was a purple soul core the size of a walnut, slowly rotating in the soul dantian filled with thunder.

When Niu Yuanping injected the refined energy into it, a magical scene happened.

The soul core, which was originally the size of a walnut, began to grow larger at a speed visible to the naked eye.

It didn't take long for it to become the size of an adult's fist.

There is a lightning light on its top, and the surface is full of brilliance!

Thunder Soul Pill!

This indicates that Niu Yuanping's demon slaying cultivation strength has successfully advanced from the fourth order to the fifth order.

Soul power, to the next level!

From now on, ordinary demons and ghosts will be unable to withstand the power of Niu Yuanping's sword.

With the improvement of his soul power, the thunder power hidden in his soul body will also be more terrifying and powerful.

The fifth-order Thunder Soul Demon Slayer was quietly born in this gray cave.

Of course.

These are all changes in Niu Yuanping's soul and body.

The rat evil who was secretly watching didn't know that Niu Yuanping was cultivating to an advanced level at this time, and he didn't know that his strength had already entered the realm of the fifth-order soul pill!

It has only one mission.

That is to keep an eye on Niu Yuanping, lock his location, and pass the news to the old boy.

Now.

Before Ma Quan's coffin.

The old boy reopened his eyes.

On its childlike face, the color of resentment was even stronger.

The old boy finally knows what the person who has made him lose so much is really like!

"Damn it!! ……”

Beneath the dirt, the cursing voices of old children reverberate.

After the curse, it begins to calm down and fall into deep thought.

Through the information transmitted by the rat evil just now, as well as the clues he had before, the old boy could judge that the human who killed the yin rat was a demon slayer with strong cultivation power.

However, the twelve demon slayers in Yunzhou City are all well known!

This person has never been seen before.

Moreover, this human with the ability to slay demons has no signs of cooperating with other demon slayers.

Dress up like a ranger......

The whereabouts are also quite mysterious......

Either hide in the common people, or stay in the deep mountains and old forests!

It's really hard for the old boy to figure it out.

It has a great interest in Niu Yuanping's bottom line!

Thereupon.

Decided to get to know this human in earnest!

Let's see what he's coming from!
