Honkai Impact, Are You Free to Come and Save the World Together?

In a certain world bubble, disasters came to the world in turn in the form of Herrschers, three in each round, totaling twelve waves of attacks. Humanity barely survived the first five waves, but its defenses were shattered by the sixth wave. At the critical moment, Bishop Otto made a desperate move and broke through the barrier of the world. However, what was beyond the breach was not the familiar universe of the Sea of ​​Trees. A strange force of unknown origin took advantage of it and instantly suppressed all the Herrschers. Before the brief ecstasy cooled down, the power turned into a cruel "game". It devours the peers and humans in this world bubble, thereby grabbing the power of the Sea of ​​Trees. The first round of selection was aimed at the pinnacle of all intelligences - Otto, Walter, Einstein, Tesla, and heads of state, all were spared and fell into the game. Fortunately, the owner of that power is eager to continue to harvest, and still leaves a glimmer of hope for the participants: those who pass the level can return to reality, but the probability of being pulled in again after returning will increase significantly; the currency obtained in the game can also be exchanged for weapons and equipment, which can be used as a means of struggle. Minors are temporarily granted asylum. What's even weirder is that the reproductive cycle in this world has been forcibly shortened - pregnancy only takes three months to give birth, but fortunately, the growth rate of children remains as normal. "What the hell kind of shithole world is this?" - Said Luo Xingchen, who had just traveled through time.
