The roars of the two ninth-level beasts seemed to pierce through the immortal cave abode, and each of their collisions was terrifying, as if intending to destroy everything in existence.
Jiang Chengxuan had no doubt that if this battle were to occur outside the immortal cave abode, in the worlds beyond the realm of immortals, it would cause devastating destruction.
Under such power, the foundation of a world could be likened to a thin wall, which could be obliterated with just a few encounters.
The increasingly terrifying noise from the battlefield made Jiang Chengxuan involuntarily hold his breath.
He condensed his perception to its limit, focusing only on the path he had used to arrive. He believed that such noise could likely be detected by most in the immortal cave abode, and it wouldn't be impossible for others or something else to come and observe.
