In the Chaos World, Immortal Venerables are akin to Dao Masters, the same level as Luo Dejie.
However, some Dao Masters in the Chaos World have a huge advantage. If they can fuse with the Chaos World, they gain an Undying Immortal Body, close to possessing undying abilities.
Jing Yan, though not at the realm of a Dao Master, by a stroke of luck, also obtained an Undying Immortal Body. As long as he remains in the Chaos World, even Immortal Emperors from the Immortal Domain would find it troublesome to annihilate him.
Immortal Venerables of the Immortal Domain do not have the Chaos World fused with them, so even the most powerful Immortal Venerables can be killed in the Immortal Domain. Immortal Venerables seeking to leave the Immortal Domain to find and fuse with a Chaos World is not entirely impossible, but the conditions are extremely harsh, perhaps even more challenging than ascending to an Immortal Emperor.
