My disciple's cultivation returns ten thousand times, so I have to be invincible.

The young man in black stared wide-eyed.

"This is……"

With his keen eyesight, he recognized what was in front of him.

This is a drop of blood.

A drop of pure divine and demonic blood!

Through this drop of blood, he had already determined the identity of the person standing before him.

A primordial god-demon who has existed since countless years ago, even more ancient than the immortal path!

"It was formed just a few years ago."

The figure in black flames said calmly.

"The bento box was used as a deposit for delivering the letter."

"I have lived for countless years, and my collection is beyond count... well, not as much as before."

"But once you deliver the letter, you will be richly rewarded."

The young man in black accepted the blood of the god and demon, nodding repeatedly.

"Don't worry, I'll take care of this."

The black-flamed figure retracted the chains.

"With your abilities, you should have a way to leave here. I won't see you off."

"Don't get any funny ideas."

"I can guarantee that no matter how skillful you are, you cannot erase this mark. If the letter does not arrive 20,000 years from now, no one can save you."

Feeling the faint but palpable pressure emanating from the other party, the young man in black felt his heart pound with fear.

He then used that escape technique to get out of the deadly ruins. He then headed towards the Immortal Alliance while continuing his "small business" using the drop of divine and demonic blood.

The significance of this drop of blood to him lies more in what he can do with it than in its physical form.

Unfortunately, Old Ma made a mistake. After passing through several fairy districts, he arrived at the Ancient Shepherd Fairy District. Just as he was doing business, a "customer" who had previously passed through the fairy districts happened to deliver the news to him.

As expected, the young man in black met his end and was chased and killed by the "customers" who had come from this place and the previous Immortal District after hearing the news.

Normally, it wouldn't have been difficult for him to escape using his escape methods, but among the customers of the Ancient Shepherd Immortal District, there was a powerful figure from an ancient lineage whose sect possessed an ancient immortal artifact, the Round Light Mirror.

After the young man in black was accidentally illuminated, he was marked. From then on, no matter where he was, the other party could see his whereabouts through the round mirror and lock onto his spatial fluctuations, preventing him from escaping using long-distance teleportation techniques.

Of all the methods the young man in black used, only the random teleportation technique could be broken, but he had already used this method to enter and exit the ruins twice before, and the damage was not light, so he could not use it again for a short period of time.

Therefore, he had no choice but to use some tricks to interfere with the circular light mirror's tracking while changing his aura and appearance, so that it could not pinpoint his exact location, but could only roughly lock onto the range, and hide on this central star.

To prevent him from escaping using the star gates, the other party even left mirror light divided from round mirrors next to each star gate hall. As long as he gets close to the star gate, even if he hides his identity and aura, he will be exposed by the mirror light.

It can truly be described as an inescapable trap.

If this giant star weren't such a crucial central star in the ancient Muxian region, the other side probably would have blown it up along with the entire star.

The young man in black could only accept his bad luck and decided to hide his identity on the star for a few years until his injuries healed, then use the random teleportation technique to escape.

I never expected that after hiding for only two years, I would sense the arrival of the Ancient Dust Immortal here today.

After listening, Jiang Ling'er couldn't help but marvel.

I think this young man in black is indeed an extraordinary person.

Not only his character and methods, but also his luck is quite peculiar.

Gu Chenxian wasn't particularly surprised.

Over the past 30,000 years, he had dealt with the person in front of him more than once, and he knew very well what kind of person he was.

"So, what you want me to erase isn't actually the mark of the round mirror, is it?"

Gu Chenxian's gaze fell on the black-clad youth's wrist.

The young man in black chuckled.

"You still understand me."

Gu Chenxian could figure it out even with his bare hands.

This guy was definitely unwilling to be forced to deliver the message, but he couldn't get rid of the mark left by the innate gods and demons no matter what he tried.
