This Is Actually the End of the World

A broken sword, two worlds. One is a world of cultivation with exhausted spiritual energy - the immortal gate is closed and one cannot become an immortal. One is an ordinary world where aura breaks out - everything changes and the doomsday is catastrophic. When Han Buyue gained the ability to travel freely between these two worlds. On the one hand, he needs to acquire knowledge in the world of practice, secret books of exercises, alchemy techniques, production of magical instruments, and find the way to become an immortal in ancient documents. We must also save refugees in the doomsday world, absorb spiritual energy, purify the environment, collect fairy materials, and create an immortal civilization after the end of the world. When the survivors in the apocalypse welcome their savior. Originally they called the terrible thing "poison gas". But in the words of ancestor Han Buyue, it is the "spiritual energy" that can make people reborn and become extraordinary. This book also has a super long title: "The Story of How I Became a God in the Cultivation World and an Ancestor in the Doomsday World"
