Generally speaking, people like Han Jiangli, who have a foul temper and an even fouler mouth, often die the quickest in Jianghu.
But he hasn't died yet, and has even been promoted to the Sun God Realm, which shows he does have some strength. Otherwise, he would probably have become a skeleton in a tomb by now and wouldn't be here spouting such bold words.
Previously, Han Jiangli's Star-Picking Hand had absorbed more than half of the Sword Qi in that Sword Domain. The intense suction force was truly terrifying, as if he really wanted to pluck the stars straight out of the sky.
Moreover, the strike he made that seemed to shatter stars was incredibly fierce. Clenching his fist like a hammer, it fell with a boom, nearly tearing Su Xin's Sword Domain aura in an instant!
Han Jiangli let out a sigh of relief; he, too, was battle-hardened. His strength had been honed from the Divinity Transformation Realm all the way to his current level through relentless fighting.
