Can't a man maintain his dignity while preparing for the end of the world? Is that too much to ask?

The Tower was all I knew... all any of us knew, and just like that, it was gone. Monsters the likes of which I'd never seen ravaged the land of my ancestors. They burst through the outer walls and stormed the city. No one could have been ready for that. But now... Now I have a second chance.

After the collapse of the known world, I woke up to find myself on the First Floor of the Tower. I was young and healthy, 18 again, and sitting in the same classroom that marked the worst days of my life. Confused and excited, I accepted this gift, deciding to use my vast knowledge of the future to climb the Tower in preparation for the end of the world.

Maybe I'll help some folks along the way? Who knows. Survival comes first.

The clock is ticking, and I'm left with only a century to build a Deck powerful enough to survive the end. Things to do... What's first? I need Essence, and I need power. I'll have to climb the Tower to acquire both of these. Some of the zealots will try to stop me, need to look out for those. What if-

Of course, he can maintain a sense of decorum while he faces these trials, right?

Everyone says he is an iceberg, but only Maya Spencer knows he is a volcano, and moreover, a volcano that is passionately unlimited for her, an indulgently pampering volcano.

A piece of divorce paper sent Xia Xinghe into a state of destitution. However, a car accident later, she transformed into a professional hacker with more money than she could ever spend. All those that have belittled, bullied and laughed at me, please line up, I’ll show you what the meaning of face-slapping is! Wait, wait, wait. That guy over there, the ex-husband that I no longer have any relations with, don’t cut in line. What, you want to help me face-slap these people? “Not only that I will help you face-slap myself!” The wickedly handsome man with billions of dollar in estate raised his own palm to slap his own face without reservation!
