Deep Abyss Knight was a xenogeneic. He had an armored knight upper body and the lower body of an octopus. Many black, metal tentacles wriggled around his lower body. It was like he had a weird shadow. Even the space around him was twisted.
Han Sen had watched the Deep Abyss Knight fight before. He knew that the Deep Abyss Knight was a dark element xenogeneic. He could release very strong and corrosive dark powers. His defensive attributes were very high. If a xenogeneic of the same level attacked his armor, one would be able to break it.
Regarding his metallic tentacles, even if they were cut off, replacements grew almost instantly. So, attacking the tentacles was pointless. One had to break the armor or body to succeed.
Han Sen was holding the Return Empty Scabbard. It counted as half a god personality armament. Although it was man-made, it was not as powerful as a real god personality armament. Still, it was a treasure that was close to true god class.
