Chapter 640: Chapter 640 Old Hatred_1

The Green-faced Demon was indeed formidable. Even Su Chengyu, who was in the seventh stage of the Foundation Establishment Realm and wielding the Dragon Slayer Sword, a weapon known for its effectiveness against beasts, found it hard to subdue him. If an ordinary officer from the Demon Slayer Department were to take his place, even a seventh or eighth-level Martial Monarch may not be a worthy opponent against this demon.

"Kid, are you a member of the Demon Slayer Department? Damn unlucky! I didn't expect to encounter a skilled fighter from the Demon Slayer Department!"

Although the Green-faced Demon hadn't been defeated, he was not finding it easy to fight against Su Chengyu. He had to be constantly on guard against the Dragon Slayer Sword whose Sword Qi also had a suppressive effect on him. Otherwise, if it weren't for his current strength, he would fear nobody unless the Martial King himself stepped in.
