Chapter 967: Gradually Increasing Materials

Du You did not hide anything but his expression was somewhat strange, "It's the Dark Swamp ability, I never expected it to be this skill. I thought I would have to find a special swamp."

Du You was truly surprised, this ability of his had been created using the swamp and even during upgrades, he utilized the swamp. He had never imagined this upgrade would turn out to rely on a giant mouth. No matter how he considered it, Du You could not figure out how this giant mouth was related to his swamp ability.

But since it was useful, then he would use it. Such a troublesome and dangerous Giant Beast would definitely not have materials of low grade. Anyway, Du You had always used the Dark Swamp ability to restrain his enemies and clear out minions.

Even if it were a little weaker, it didn't matter, Du You never expected to use the ability to contend with experts.
