Extreme. Boundary

How can we live without death? Listen to me blowing for you. Billions of vast worlds, each with its own differences, slowly living forever, taking different paths to reach the same destination. Those who are not yet immortal are searching for immortality, but they cannot find the method or the secret. Those who have become immortal remain motionless in the long river of time. What is their daily life like? Is it seeking the ultimate in martial arts or the ultimate in numbers? It is also the mystery of heaven and earth, the mystery of the true nature...
