Their strength did not only lie in their use of the rules of the great Dao between heaven and earth.
Their immortal bodies and immortal senses had already evolved and were able to heal themselves in an extremely short time, healing their injuries.
"What?"
The Tian clan's quasi-Immortal King frowned slightly. He lowered his head and his eyes. His quasi-Immortal King Power couldn't fully heal him. He could only keep his injuries from worsening, but he couldn't fully recover.
Immediately, he understood.
At this moment, the lines of the heaven and earth killing formation carved in the space had once been personally made by an extremely powerful creature, which contained the power of that cultivator. Now, that power was raging in his body, as if it was destroying his internal organs, making him unable to heal himself.
