Chapter 136 Sixth Level·Invisibility

After Xu Mu finished speaking, the surroundings were quiet, with no movement except the waves and sea breeze.

"well!"

Xu Mu sighed, squeezed the magic formula with his hand, and a green wind blade condensed in front of his eyes and shot towards the sea.

Buzz!

The originally calm sea surface immediately flickered with light, blocking the wind blade.

Several figures also appeared.

"I didn't expect you to be able to discover us, you are quite capable!"

There were five people in total, all of whom were in the late stage of Qi training. After realizing that they had been exposed, they immediately surrounded Xu Mu.

The speaker was a woman, wearing black clothes and looking haughty.

"How can you come out and hang out if you don't have the ability!" Xu Mu laughed.

Seeing that Xu Mu was not afraid at all and did not make any move to escape, the woman in black frowned slightly.

However, in the current situation, there is no possibility of stopping.

"Are you from that gang? Why do you want to come to our Iron Corpse Gang?" the woman asked coldly.

"Do you think I can tell?"

Xu Mu was still smiling, which made the woman very annoyed.

"I won't tell you, but I want to see how tough your mouth is! Do it!"

The woman in black snorted coldly, slapped the storage bag on her waist, and several black lights flew out, shooting towards Xu Mu at high speed.

"The third-level flying needle weapon is quite interesting!"

Xu Mu reached out and grabbed it, and black light fell into his palm, turning into several black flying needles as long as his index finger.

"How can it be?!!"

The way Xu Mu raised his hand to grab the magic weapon made the pupils of the five people tremble.

"escape!"

There was almost no need to hesitate. The five people had a flash of inspiration and were about to break the road.

When you see something bad, run away immediately!

This is the law of survival in the open sea.

"I finally led you so far away, how can I let you run away?"

Xu Mu flicked his wrist, and lightning suddenly appeared. The black flying needle in his hand shot out at lightning speed.

Puff puff!

The flying needle instantly penetrated the protective spiritual light and passed through the heads of several people.

"Um?"

What surprised Xu Mu was that the woman in black had a layer of blood on her body and blocked it.

You know, with his current physical training skills, he can even kill people in the late stage of foundation building.

Although it was just a casual attack, it was not something that a late Qi practitioner could withstand.

"Looks like I caught a big fish!"

Xu Mu raised the corners of his mouth slightly.

The woman in black who was interrupted from casting the spell quickly patted the storage bag in shock, and a black aura flew out from it, turning into a refined corpse with blood-red eyes and hook-like fingers.

The corpse refining roared and rushed towards Xu Mu without hesitation.

At the same time, the woman took out a high-level flying escape talisman and was about to run away again.

"We even have corpses in the foundation-building stage, so we can't let you go!"

Xu Mu was surrounded by thunder and lightning, and he slapped the Foundation Establishment Stage Refined Corpse that came towards him and flew it away.

It would be a pity to destroy the corpse refining in the foundation building stage.

Then he dodged and caught up with the escaping woman in black. Lightning surged, and half of her body was broken into pieces with one punch.

Roar!

The refining corpse was about to pounce on him, but Xu Mu grabbed his head and used the corpse control technique to completely refine it in just a few breaths, wielding it like an arm.

Next, he naturally used Blue Bird to extract the souls of several people and read their memories.

I didn't expect it to be a surprise.

This woman in black is actually the granddaughter and youngest son of the Iron Corpse Gang elder...

This old guy is really nothing!

Xu Mu couldn't help but curse.

But in the territory of the devil, this kind of thing is very common.

In order to keep their bloodline pure enough and cultivate outstanding descendants, some families even refuse to marry outsiders at all.

What to do with those deformed children? Naturally, they were killed to make materials.

Magical weapons made from the same bloodline are more powerful.

He got a lot of useful information from this woman.

The Iron Corpse Gang is indeed arresting a large number of low-level monks in order to refine blood essence, but the purpose is not to use the Iron Corpse Master to break through the golden elixir.

But for the purpose of refining the corpse!

Master Iron Corpse found a corpse of excellent quality from somewhere, and he has been immersed in making the corpse recently.

"Just making a refined corpse in the late stage of foundation building shouldn't require so much blood essence!"

"This corpse looks very unusual, let's go and take a look!"

After collecting all the valuables from these people, Xu Mu changed his appearance and returned to the Floating Corpse Island.

Relying on the memory he read, Xu Mu easily sneaked into the Iron Corpse Gang's location.

Although his hidden methods cannot deceive people in the Golden Core Stage, they can still be used to deceive people in the Foundation Establishment Stage.

So it didn't take much effort to find Master Iron Corpse's corpse refining place.

But it's not that easy to get into it.

In a retreat place for practitioners, even those who are close to it will be on guard.

Xu Mu was not reckless and slowly waited for the opportunity.

After squatting for three or four days, I finally found an opportunity.

Because of the need for a constant supply of essence and blood, a group of elite disciples from the Iron Corpse Gang would enter at a fixed time every day.

But it's not that easy to blend into the team.

The inspections when entering and exiting were very strict, even if Xu Mu could control his breath and change his appearance, it would be useless.

However, Xu Mu has no intention of joining the team. With his system, he has many ways to enter.

He opened the system and started searching, and soon found the right skill.

[Level 6·Introduction to Invisibility; 41/3200]!

Over the years, Xu Mu has never stopped learning high-level spells, but he only has a superficial taste.

One is that it’s unnecessary, and the other is that it’s too difficult!

For sixth-level spells, it will take at least several years, or even more than ten years, to reach a high level with normal practice.

Xu Mu didn't have enough time to improve his cultivation, so he had time to practice.

It is even more impossible to rely on luck value improvement!

He has too many skills that need to be improved. These spells, which are not considered powerful and have relatively low return on investment, are not ranked at all.

What I am learning is entirely to cope with the current situation.

Xu Mu did not improve much. He only raised the invisibility technique to a perfect level and integrated the first-level invisibility technique at the same time.

Compared with the first-level invisibility technique, the sixth-level invisibility technique can not only hide the body shape, but also conceal the perception of spiritual thoughts.

The perfect sixth-level invisibility technique can just deceive the perception of spiritual thoughts in the later stages of foundation building.

Xu Mu then waited for an opportunity, followed the team delivering blood essence, and easily sneaked into Master Iron Corpse's retreat.

The essence and blood continued to be transferred, and Xu Mu followed closely until finally reaching an underground palace.

"Gang leader! Today's blood essence has been delivered!"

A disciple of the Iron Corpse Gang knelt at the door of the underground palace, respectfully placed several jade bottles containing blood essence at the door, reported the situation and retreated, closing the formation at the same time.

Xu Mu was stuck here.

The invisibility spell has a limited time and may be exposed at any time.

However, there was not much panic on Xu Mu's face. He squatted in the corner and waited patiently.

After a while, with a creak, the heavy stone door slowly opened, and a thin figure covered in black robes walked out. He skillfully picked up the jade bottle on the ground and prepared to return.

Xu Mu's eyes flashed, knowing that this might be the only chance. The Thunder Sword suddenly appeared in his hand, and his whole body suddenly rose up, turning into a golden thunder, and slashed it with one sword.

Poof!

The black robe had no time to react before he was struck by the sword light and cut into two pieces, revealing the shriveled body inside.

"who!!!"

A roar sounded from behind the stone door.
