Su Chengyu's sword struck with formidable power, but it was impossible for him to kill the Ninth Grade Martial King, Lei Donghai, with a single blow.
When the smoke and dust dissipated, Lei Donghai's figure emerged, his clothes ragged and drenched in blood. He looked like a bloodied man, appearing to have suffered severe injuries.
However, in reality, Lei Donghai had only sustained superficial injuries. The physical defensiveness of a Martial King Realm was extremely high, impervious to blades and weapons. Moreover, Lei Donghai had managed to break free from the Ruyi Golden Ring's constraint and activated his internal energy to block the Sword Qi, resulting in only minor external injuries.
Despite this, Lei Donghai felt a shudder of fright. Had the Ruyi Golden Ring ensnared him for a moment longer, even though he would not have been killed by the sword, he would have suffered severe injuries.
