Comments of chapter undefined of Simulation Towards Immortality In A Group Chat

I've always had a question Does this predecessor transmigrator (head of the demon sect) keep his memory since after they both met the first time since all simulation are like parallel universes and shii only Wang ping is meant to keep memory but I don't know if this demon sect guy has a way to remember or send back memory to the original timeline from the simulated one cause I know he was once able to appear from the simulated to the real when he schemed against MC using all rewards
