Eternal Thief

Ace wanted to use the intermediate item upgrade token on the thousand-face mask first, but he saved it when he thought about the Thievish Soul Cord would reach the grade-8 if he used it on it.

But he still hesitated, so he decided to use it on the base of his situation.

Now that he was in this unknown secret realm, he needed a strong weapon, and the black blade swords were no longer summoned at this moment.

So, the thievish soul cored was the beast choice that could restrain enemies, and with it upgrading to grade-8, he would be virtually unstoppable!

The system instantly complied after receiving Ace's order.

======

New information about the abilities started to enter Ace's mind, and not only that, but another part of Thievish Soul Cord Control-Final appeared with all those memories.

Ace was astonished since he didn't think grade-8 would bring such a massive change in the Thievish Soul Cord.

Although the last two abilities were restrained by the system but just the newly opened ability was enough to make Ace's heartbeat race. He was really glad he decided to upgrade the Thievish Soul Cord.

He looked at his wrist, and a translucent bracelet materialized with a beautiful ethereal black pattern on it.

He no longer needed to hide it with anything because now it had an innate concealment function that couldn't be detected unless a grade-9 scanning formation was used!

Ace then made it disappear again, but now he could feel a connection with it and control it even more swiftly.

After he was done with the upgrade, he looked at the wall, which had a passage behind it.

Suddenly, the Martial Thief Sword Core in his martial space trembled slightly before dark swords in the same shape as his long sword started to materialize behind him. It was the Hundred Shadow Mirage of Dual Sword Mirage Art.

However, those swords were no longer mere mirages but real, and they were filled with martial shadow sword intent!

This was the realm of Sword in Mind, where he could control the sword with thought, and he no longer needed to hold any hold to make use of sword intent in this realm.

When Ace comprehended the sword intent, he discovered that law intent could be used with both martial and soul Qi.

With the Qi you used them with, they would become either soul law intent or martial law intent, and the Sky Sword Manual was also built around this concept that any cultivator with either martial or soul sword intent could cultivate it.

It was like a unique cultivation method, and Ace guessed that it was probably a cultivation technique from higher heaven.

Whichever the case was, this inspired him to create both sword cores for the soul and martial path since he could use both types of intents.

Lastly, Ace also saw the endless path for his sword cores when he comprehended the full sword intent and created the sword cores. He even imbued his Dual Sword Mirage Art and Dark Life Plexus Sword Art into it.

As for the Sky Sword, it would also be going to become the foundation and part of his thievish sword path.

So, he called this new technique which would be based on his Martial Thief Sword Crore and Soul Thief Sword Core…

'Eternal Thief's Swords; Martial Sword Wave!'

The next moment, a hundred swords behind him flashed in dark streaks and diced the entire left wall.

Then the thievish soul cord suddenly shot from his sleeve, and like a whip, it lashed onto the diced wall and blasted open a dark tunnel before returning to Ace's sleeve.

Ace then waited and looked at the map, and when no one appeared, he finally moved and closed the fate map to preserve his soul Qi. His thief sense should be sufficient in the red fate map location.

He can always activate it again when his thief sense picks up something.

But before Ace left, he looked at the teleportation room, and his eyes suddenly turned pitch black!

Suddenly, a tiny thief symbol appeared within the formation's symbols before it vanished without a trace.

Afterward, Ace's eyes turn back to normal. He just used the Thief's Mark innate soul ability he awakened after forming the red soul core!

=====

[Thief's Mark]

[Description: Brand anything with a special Thief's Mark, which could be detected from anywhere as long as the Thief's Mark exists!]

[Limitation (1): Thief Mark can only be used on Living Beings with weaker souls than Host, and it will vanish after the victim's death or if the victim's soul strength surpasses Host's!]

[Limitation (2): Thief Mark can be used on any non-living being but can be destroyed with the non-living being.]

[Limitation (3): Martial Sense, Soul Sense of 7th Realm, and Rune Symbols of Grade-7 can detect the presence of Thief's Mark!]

[Current Thief's Mark Limit: 50]

=====

This ability was quite useful for treasure or person tracking as long as no one discovered it.

Ace used a thief's mark in this room just in case he might discover the material to use the formation, and then he even used a concealment formation to hide it just like before. Although he didn't know it should be hidden for a reason.

Afterward, Ace used lightning steps and moved toward the only passage around here, which hopefully led to the exit.

Because even above three miles or below, he couldn't feel anything, and this was the only way open!
