If You Don't Upgrade for Seven Days, You Will Die.

Mu Yun is a time traveler, but his system betrayed him. It caused him to plummet at the peak of his life. As a result, the whole world noticed that he was an alien, and everything he was familiar with was turned against him. Therefore, Mu Yun died like this. But forget it if you die, and then be tried by a bullshit court and sentenced to what, a Gugornian confinement? Fortunately, the court confirmed Mu Yun's innocence by searching his memory. Instead, he was thrown into the next world. Mu Yun originally thought that he could breathe a sigh of relief and enjoy life. But tell me, what does it mean that your level limit is only level 10, but if you don't level up one day before level 50, you will die? Um? No, if you want him to die, do you need so many twists and turns?
