The key was that Lu Xiaotian still had no idea how to deal with Rahu. Even Shixing and the eminent monks he had summoned had failed to destroy Rahu, and Lu Xiaotian knew he lacked the ability to accomplish such a feat. On the surface of Rahu's body, where all vitality had faded, Lu Xiaotian was confident he could protect himself. But no one knew what might happen if he ventured inside. Since he couldn't kill Rahu, why stay and make a futile effort?
"I'll take my leave!" Lu Xiaotian rose to his feet and didn't linger. He had originally come to this realm only to confirm whether Luo Qing was truly still alive. He hadn't expected to learn, by chance, the secret that had been hidden in this realm for countless years. He had also unexpectedly obtained the inheritance of the eminent monk Shixingkong, enough to sustain his cultivation after entering the Immortal Realm. It was an unexpected boon.
The one thing that wasn't quite so satisfying was that he had, in a way, made an enemy of Rahu. Even if Rahu kept his promise this time and restrained that surging demonic qi when he left this realm, if they met again in the future, Rahu surely wouldn't hesitate to send him to his grave with a single move.
Lu Xiaotian shook his head, pushing these useless thoughts aside. He had already made a small but significant enemy of Rahu, and there was nothing he could do to change that. As for what came later, he would let it be. The places he was headed had little overlap with the Devil Race, and a formidable Demonic Beast like Rahu would be a great figure even in the Devil Realm, someone whose every step could make the Immortal Realm tremble.
