Reentering the Shadow World was extremely dangerous, and Li Xiuchang knew that all too well.
The last time, the Confucian Sage's shadow had nearly kept him there. Now, that shadow had advanced into the "Heart Questioning Dao Ancestor's shadow," making it even stronger than before.
If he went to the Shadow World again without Dao Ancestor cultivation, he would basically be walking to his death.
That was why the Heart Questioning Dao Ancestor urged Li Xiuchang to achieve the Dao Ancestor realm as soon as possible. Only then would he have the strength to retrieve the Buddha Ancestor's reincarnated body.
Li Xiuchang asked in confusion, "How could the Buddha Ancestor's reincarnated body be in danger? Even if he couldn't return, he shouldn't be in danger, right?"
After the Buddha Ancestor's nirvana, it was equivalent to opening his fourth life. Although he did not need to start cultivating from scratch like an ordinary reincarnation, his strength would inevitably be greatly reduced.
Take Gui Wuyan, for example. Before nirvana, he had been a Daluo Golden Immortal, but after nirvana, his strength had temporarily become stuck at the Void Refinement Stage.
Although he would recover quickly once he awakened, he still needed time to recover.
The same principle applied to the Buddha Ancestor. After nirvana, he certainly could not restore his peak combat strength in a short time. He might possess only the strength of an ordinary Daluo Golden Immortal, or even merely the combat strength of a Primordial Unity Golden Immortal.
With such combat strength, the Shadow World was indeed not very safe.
But one had to know that, like the Confucian Sage, the Buddha Ancestor could restore his identity and strength from his first life at any time!
In other words, he could abandon the strength of his fourth life and
