Patching the Earth

Stuck a thousand meters deep in the ocean during a fatal mission? And there is only five minutes of self-rescue time? Just crossed over and faced the beginning of hell? But when the abandoned modern city on the seabed came into view, Ou Heng realized that he had entered a completely different world. As a time traveler with a golden finger, he originally thought he could shine in another world, but his identity was exposed on the spot: "You are not the original Ou Heng. You are actually a time traveler, right?" ......... This world. The mantle was disordered, the glaciers melted, and the earth completely turned into an ocean world. Human civilization still sticks to this home that is no longer suitable. Space-time locking theory, world line collapse theory, parallel universe convergence effect, anchoring events, civilization zeroing, the mystery hidden in the time gap, interstellar immigration and the overall plan to patch up the earth... When time travel is no longer a fantasy in literary works, but a profession set up to change the future, where will fate push Ou Heng, the time traveler, to go? They said that the mission of the Purge is to travel through four, five, and six dimensions of time and space to patch up the world line that has deviated from the direction. They said that the mortality rate of the Purge was as high as 80%, and they would fall into confusion at any time. But Ou Heng had no choice, and he became more and more determined. Because he understands that if civilization must return to zero, then he can only change it with his own hands. If the future is in tatters, someone will have to mend it.
