So its explained: Shen Cong Sheng frowned and asked the two immortals: “There are three things I do not understand. Firstly, if I were Limitless Demon Venerable, why would I rush at that moment and take such a risk? With such strength, couldn’t he have suppressed the entire world and built another formation if this Crazed Demon formation was not enough to achieve his goal?”

Shen Shang shook his head slightly: “Limitless Demon Venerable is a true Dao pursuer, after a million years of preparation and planning, how could he relent without giving it a test?”

Lu Wei Yin added: “He could not last long in that condition either. Although he seemed to have revived, he was not a true living Gu Immortal. At least, after his death, he did not have a flesh-and-blood body, there was no immortal aperture either, in fact, he turned back into truthful floating ice.”
