When Ji Xun woke up, he found himself in an endless "Pagoda" with all his memory lost. Every seven days, a cruel "trial" will eliminate everyone, and then everything restarts, and the cycle begins again.
Ji Xun's special ability is that he can sense the "echo" of emotions remaining in reincarnation. Relying on it, he avoided the fatal trap and changed the outcome of the group's destruction. But this is not the script of The Chosen One, but a conspiracy that has been carefully planned countless times. A companion who seems to be the most reliable is leading them to the next abyss with a smile; but the "echo" he trusts most is actually the only way to survive paved with despair.
