Seeing the endless sword aura coming, the Myriad Flames Corpse King ran quickly.

It scurried underground like a gopher.

There was an ancient coffin placed in the underground space.

Without hesitation, it quickly lay down in the coffin and closed the lid.

"Phew! I'm finally safe. This is an Emperor-grade defensive artifact. It's definitely impossible to break!"

"But when did such a powerful character come to the Fire Spirit Islands?"

Hiding inside, it calmed down a little.

This coffin was extremely hard, and it was confident in it.

Three Starlight-level experts had once attacked together for a few hours.

In the end, they were all exhausted and could not break open this coffin.

This was also why the Myriad Flames Corpse King could survive for so many years.

In ten seconds, a deep pit dozens of meters wide had been blasted into the ground.

Zhou Han also saw this coffin and activated Appraisal to check its attributes.

[Soul Returning Coffin]

[Grade: Emperor]

[Durability: 1,000,000]

[Effect: Damage taken is reduced by 50%, durability recovered by 3% per second.]

[Description: Refined from extraterrestrial meteorite iron. It can provide a powerful defense.]

"It's actually Emperor-grade. I didn't expect you to have such a thing!"

After reading it, Zhou Han was a little surprised. He did not expect the other party to have an Emperor-grade artifact.

However, on second thought, it was a Boss after all. All creatures on the Godfiend Continent had their own consciousness.

This way, they could also develop on their own and kill monsters to level up.

It was not surprising that it had an Emperor-grade artifact.

"Hahaha! I advise you not to waste your effort! Leave as soon as possible! It's good for both of us!"

At this moment, when the Myriad Flames Corpse King heard Zhou Han's voice, it started to show off again.

With a total of a million durability and a 50% damage reduction, it could still recover 3% durability per second.

In other words, he had to deal more than 60,000 damage per second to destroy the [Soul Returning Coffin].

The Corpse King naturally did not think that Zhou Han could do it. Even three Starlight-level experts could not do it. How could a young man do it?

Therefore, it was naturally confident when it said this.

"For nothing? It seems you know nothing about true power!"

Zhou Han's eyes turned sharp. With a thought, all the sword aura attacked the [Soul Returning Coffin].

If it was said that the previous version of [Myriad Swords Return] might be a little difficult, then there were no additional enemies to kill, so he could not increase all his attributes.

However, the upgraded [Extreme Mastery—Myriad Swords Return] was different. As long as he activated the skill, his attributes would increase by six times.

Coupled with the multiplier of the skill's damage, it was easy to deal millions of damage.

Sizzle! Sizzle!

After the violent sword aura hit, sparks flew.

"Give up as soon as possible! How can you easily shake an Emperor-grade artifact?"

The Corpse King, who was in the Soul Returning Coffin, could only be passively beaten up and could not move.

Seeing that there seemed to be no sign of breaking, its words were filled with sarcasm.

"Hehe, you… what?"

"Damn it!"

There was a loud crack and a huge crack appeared.

Then, it continued to spread like spider silk, and the Soul Returning Coffin was filled with cracks.

The Corpse King's expression changed, and its smile gradually condensed. Its pale face was about to become transparent.

"Stop! Stop it, you bastard!"

Many lights appeared in the originally dark coffin.

The Corpse King knew that this was a sign that it was about to shatter and immediately shouted angrily.

"Please, stop! Stop now!"

It naturally knew the consequences of shattering.

The roar failed and immediately turned into a plea for mercy.

Zhou Han smiled coldly and was unmoved.

The sword aura was even richer. A large hole had already been torn open in the Soul Returning Coffin.

"Just wait. The Corpse Race won't let you off…"

The vicious voice became weaker and was quickly buried by the sword lights that filled the sky.

Hearing the system's kill notification, Zhou Han knew that the other party had been completely annihilated.

"Let's see if anything good dropped!"

Zhou Han waved his hand, and the violent wind blew away the dust.

Covering his nose, he walked over.

Three things dropped.

First was a skill book, [Corpse Refinement Technique], which was used to refine corpses.

Although it was Diamond-grade, Zhou Han still felt that it was evil and smelly.

'I'm sorry, I really can't do it.'

There was no need to learn such a skill.

He opened the Swordsman badge and directly exchanged it for 200 contribution points.

The second was a Diamond-grade ring, the Ice Moon Ring. It was ice-type and did not match Zhou Han.

Zhou Han already had the [Lightness Ring], so he did not consider this and directly sold it.

The third sword was a [Wolf Soul Bow]. Zhou Han had no use for it.

"This luck isn't good! None of them are useful!"

Shaking his head, Zhou Han began to collect the mission materials, [Top-grade Fire Crystal].

A huge pit had already been created just now, causing many crystal mines to be exposed.

It saved digging time.

[Top-grade Fire Crystal discovered. Do you want to collect it?]

When Zhou Han's hand reached out and touched a large area of purple-red stones,

the system gave a collect prompt, and the relevant description appeared.

[Top-grade Fire Crystal]

[Grade: Diamond]

[Effect: Main materials for upgrading fire skills, weapon enchantment, and attribute cultivation.]
