Chapter 602: Innate Soul Ability: Thief’s Mark

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.
