Behind Me is the Entire History of Mankind!

Similar to the fourth natural disaster, the future world is on the verge of destruction, and at the final moment it is discovered that ether particles can travel through the timeline. It has been discovered in countless timelines that development that relies on traveling through time and space will tend to be destroyed. Then start again, start over, conceal time travel, and inspire human beings to fight.

After obtaining a time machine, how to rebuild civilization in a future where human civilization has been destroyed, and how to deal with the enemies that destroy human civilization? Hiding the future as a game, turning humans in the past into the fourth natural disaster, and helping them rebuild civilization in the future? This is a way, but it is not enough. Just being a "player" is not enough for this civilization to form quickly. A time machine can not only travel through time and space... Einstein, Planck, Mendeleev... Leonardo da Vinci, all the scientists who have left a mark in human history. If they appeared in a group in an era and gathered the wisdom of the entire human civilization, what kind of power would they have? ... A player: "How come this person named Leonardo da Vinci can draw paintings that look so similar to the real Leonardo da Vinci? Is AI so advanced now?" "There is also this man named Einstein, who actually created cold nuclear fusion with Fermi! Their theories are actually feasible!"

It's interesting up front. I like to see the interaction between the protagonist and Einstein, especially some of the dialogue before picking up Einstein. When I saw it on the shelves, there was nothing particularly attractive to me so I clicked on it. It doesn't have the feeling of the Fourth Scourge, and it doesn't have the fun of the game.

The mastermind behind the Fourth Disaster disguises the future as a game and allows players to help save the future. What is special is that the NPCs are basically invited familiar scientists, such as Einstein.
