Ao Tian didn't spend much time rushing through the River of Time with Su Chengyu, as even with Ao Tian's current strength, he couldn't maintain it for long.
Moreover, Ao Tian knew Su Chengyu was in an even worse condition than himself, and after landing, it was up to him to ensure Su Chengyu's safety.
In a secluded cave, Ao Tian revealed his true form, placed Su Chengyu on the ground, then shrank down to the appearance he had when Su Chengyu first met him.
This scene made Su Chengyu somewhat nostalgic, and he couldn't help but tease: "You haven't overexerted yourself in this battle and fallen back to a Big Monster level, have you?"
"Get lost, I'm just a bit exhausted, even if I'm weak now, I'm still much better off than you."
"Really?"
Su Chengyu looked down at his body and blinked, "I think I'm fine."
Compared to the last time he used the Immortal Decapitating Sword in the Capital City, his condition now seemed much better.
