At the same time, the deepest part of the Shura Palace.

This is a dark and deep hall, and the hall is pitch black and has no light source.

Suddenly, a sound of chain knocking came out, and Dingling clanged, crisp and loud.

Then in the middle of the palace, two red balls of light appeared, looking like some kind of ghost opened its eyes.

"Kill... Kill... Kill all the invaders..." A hoarse voice came from where the light group was.

The sound is blurry and there is a little low noise, unlike ordinary people talking.

And as this sound rang out, countless red light balls lit up in the palace.

Then black shadows rushed out and rushed around the palace.

Judging from the outline of the body, these black shadows are obviously not humans, but monsters.

...

At the same time.

"Ten Thousand Demon Pill?"

After Lei Yi heard this name, he knew that this pill was not a good thing.

"Yes, Wanmo Pill, this is the unique secret pill of Shura Palace. Only the commander Yin Bubai can refine it. It is a pill that can greatly improve its cultivation!"

Yuan Ruomeng said, looking at the dark pill in the air, and said lightly: "It's a pity that the side effects of this pill are also very great. If the cultivator swallows it, he will probably not be able to withstand the surging medicinal power and eventually die!"

"It's so exaggerated, then don't there be many people who can swallow this pill?" Lei Yi also looked at the pill, somewhat doubting the effectiveness of this pill.

"You are right. Even in the heyday of our sect, there are not many people who can swallow the Ten Thousand Demon Pills. In addition to the violent medicinal power, this pill has other side effects. The most fearful thing is the risk of enchanting the demons brought by this pill!"

As he said that, Yuan Ruomeng sighed and recalled: "As the name suggests, the spiritual materials used for refining are all taken from monsters, and are supplemented by the blood of the cultivator's heart. Therefore, when this pill is refined, all the spiritual materials injected contain powerful resentment and murderous intent. The moment when the ten thousand demon pills are formed is also the moment when resentment is concentrated, and this resentment will not dissipate with time, but will continue to accumulate in the pill. Once someone swallows this pill, this resentment will also explode in the body of the swallower."

Speaking of this, she pointed to the blood clouds in the sky.

"Look, the blood cloud gathers but does not disperse, condenses as the essence. From the scale, it should have a quantity of more than ten thousand people. This means that when the Ten Thousand Demon Pill was sacrificed and refined, at least ten thousand cultivators' blood was used."

"No wonder, I just said why the smell of blood here is so heavy. It turns out that it is all because of this pill!"

Lei Yi looked at the blood clouds condensed around the pills in the air, his eyebrows were a little solemn.

He can never think of such a thing as refining with human blood or having a heart.

At this moment, the blood clouds in the sky also changed.

The undispersed cloud began to gather towards the elixir in the center, leaving thin blood-colored textures on its surface.

"This Ten Thousand Demon Pill has been successfully refined, but why can it be successful?" Yuan Ruomeng felt even more strange as the pill gradually took shape.

Although she specializes in formations, she also has a lot of knowledge about alchemy techniques, so she knows some information about the Ten Thousand Demon Pills.

The time period for refining this pill is indeed not short, but it is impossible for one to remain in the state of refining from that year until now.

Therefore, this pill was obviously refined later, and the person who refined the pills could only be Yin Bubai.

Unfortunately, Yuan Ruomeng and Yin Bubai are not familiar with each other, and even Lei Wanhong and others have never dealt with each other much.

Wusheng Hall and Shura Hall are two other alternatives among the eight halls, and they have little relationship with the other six halls.

"Anyway, let's be careful. This alchemy person should still be in the Shura Palace. The other party may be Yin Bubai, but if not, the problem will be big!"

Yuan Ruomeng said, and quickly pinched his hands and hit the alchemy in the middle one by one.

Above it, the Ten Thousand Demon Pill completely absorbed the blood cloud, and the pill finally took shape.

The surface of this pill is filled with thin blood patterns, which looks like blood vessels in the human body, dense and complex, making the entire pill full of blood.

Not only that, after becoming a pill, the Ten Thousand Demon Pill seemed to be alive, and it was still "beating" and making a "plop" sound.

It looks like a heart.

With Yuan Ruomeng's magic tricks being used, a gentle force wrapped around the Ten Thousand Demon Pill, took it off and fell into the hands of the woman.

"We don't need this pill, keep it for you!"

Without saying a word, the other party stuffed the pill into Lei Yi's hand.

However, she later reminded: "With your current strength, don't swallow this pill rashly, otherwise there will be a risk of being possessed by the devil or even exploding the body. When the number of your divine orifices reaches 72, using the overwhelming medicinal power of this pill, you may be able to hit the bottleneck in the later stage. Of course, the resentment of this pill should not be underestimated. After you go out, you must not only practice, but also find a remote and hidden place to ensure that there is no danger before you can swallow it!"

Seeing that Yuan Ruomeng was so serious, Lei Yi naturally carefully packed the pills, packed them in a jade box, and even put them on several talismans to seal them.

As the Wanmo Pill was taken down, the partial hall had no value anymore, so Lei Yi and others naturally continued to move forward.

Just after they left the side hall, a gap suddenly opened on a stone wall in the hall, and then a black shadow rushed out.

The black shadow rests on all fours and has a slender body, but it is not human-shaped.

When he walked to the center of the medicine cauldron, he found that he was one step late and the Wanmo Pill inside had been taken away.

"No..." Seeing this, the black shadow let out a roar full of resentment, mixed with a hint of human voice.

...

Shura Hall, main hall.

Walking all the way from the side hall where the alchemy is refined, there is no danger.

Soon, Lei Yi and the other two arrived at the main hall.

This is also the place that Lei Yi is most looking forward to, because there is the secret boxing technique of Shura Palace here.

According to Yuan Ruomeng, this boxing technique was not created by Potian Xuanzong, but was studied hard by the leaders of the Shura Palace imitating the attack methods of monsters, and combined with the foundation of Potian Xuanzong.

This boxing technique has no name, and there is no systematic learning method, because this boxing technique was still unfinished back then.

Unfortunately, because something happened back then, this boxing technique would never be completed.

But when they arrived at the main hall, all their passion was extinguished.

"Who is so unkind!" Lei Yi looked at the palace wall and cursed.

Because the wall of the palace that records boxing skills was actually scratched, with countless claw marks on it.

Not to mention a single word, even if there is a pattern, no one can see it.

Lei Yi wanted to scold people.

But when I thought that the person who destroyed the palace wall must not be a human being, I extinguished the plan to swear.

The palace wall is destroyed, so the secret boxing technique is not unavailable for him?

"You don't have to be so excited. It is not the palace wall that records the fist. It is only the secret technique of the blood path of the Shura Palace!" But Yuan Ruomeng signaled Lei Yi to calm down.

She walked to the middle of the main hall, her eyes stayed on the ground under her feet for a moment, and then she knew it.

Yuan Ruomeng took a few steps forward, then raised her foot and tapped the ground several times, making a "click-click" sound.

After some operation, several areas in the middle of the main hall suddenly sank downward, as if some mechanism was activated.

Then amid a harsh friction sound, nearly ten statues slowly rose from the underground of the hall.

"These are..." Looking at the rising statues, Lei Yi was confused.

"These stone statues are the characteristics of my Potian Xuan Sect. You can tell if you press your hand on it." Yuan Ruomeng smiled softly and signaled.

Lei Yi didn't doubt anything. Anyway, they were all big stone statues, so what could they do?

He walked to one of the wolf-shaped stone statues with wings and pressed his hand against the foot of the statue.

At this moment, a strange energy suddenly came out from the stone statue, spreading throughout Lei Yi's body.

This feeling was like an electric shock to his body, giving him a hint of paralysis.

But then, the scene in front of Lei Yi suddenly changed, and his whole mind was pulled in by this force.

Endless desert area.

In the desolation, countless monsters were raging, eating various corpses and fighting each other.

Huge monsters attack weak monsters, wanting monsters of the same size to fight together, the scene is bloody and cruel.

Aww—

Suddenly, a wolf howl sounded.

On the earth, all the monsters seemed to hear the death knell and all took action.

But unfortunately, they were just ready to take action, but they were already one step late.

At some point, countless black shadows appeared in the sky. They were dense packs of wolves, but they had their wings on their backs, and each one could soar in the sky.

The wolves in the sky formed a dense square formation and launched an attack on all the monsters below.

Next, what appeared before Lei Yi was a one-sided massacre.

He saw countless monsters being killed, the bravery and good at fighting, and... the top strategy.

The wolf pack killed one monster after another, and even monsters hundreds of times larger than the wolf, fell under the encirclement of the wolf pack.

"What a flexible wolf pack, like a commander of a hundred battles, knows how to use tactics... No, this is not tactics, but experience against the enemy and on-the-spot response. This is a change based on the enemy's actions..."

Soon, Lei Yi understood.
To be continued...
