RE Restarts the World

On this day, Ian, the world's top professional e-sports player, was completing the most difficult copy of a certain game for the first time. A line of small words suddenly appeared in the upper right corner of everyone's sight in the world: "The first phase of the truth of the world has been discovered, which took 6782.066 Years. Countdown to world restart: 24:00:00" People began to panic, fear, fear, and finally despair... But Ian, who had become indifferent to life, was still fighting the final BOSS in the game... For him, there was nothing worth missing in this world. 24 Hours later, the world restarts. I don't know how many years later, the sixteen-year-old boy Ian finally woke up. In a world intertwined with darkness and unknown chaos, he met Leah, a cat girl with white cat ears and tail... How did he discover the truth of the world, and could he change his ending? It's all here: RE restarts the world.
