Jiang Li and Bai Hongtu both had a good relationship with Old Buddha Xumi, who had shared his theories with them when he was bored.
Regrettably, Xumi Old Buddha's theory was just a hypothesis derived from his contemplation of Buddhist law, with no evidence to back it up.
Old Buddha once inquired Immortal Elder Changcun about this theory, with Jiang Li and Bai Hongtu standing by; the elder's answer was disappointing.
He stated that even the Immortal Realm had no research on this, and he had no information about whether a parallel world really existed.
If even the Immortal Realm didn't have this knowledge, it was simply impossible for just Old Buddha Xumi to figure anything out. So, in the end, the Old Buddha only muttered a Buddhist chant and never broached the subject again.
"If the Old Buddha were still alive, seeing you would surely make him happy," Jiang Li suddenly said to the Real Man of Void, leaving him puzzled.
