How Can a Poor Boy Become a Great Leader in the Last Days?

My name is Liu Yu, I have a master's degree in astronomy. I have just been resigned. On my way to find a job, I encountered the biggest crisis in my life... "Is my happy life coming? Am I so handsome? Is my sister going to kiss me? Hee hee hee, come on, I accept, come on, eh? What is that? WC, such a big mouth? You want to eat people, help me, don't bite me"...... Intention: Doomsday in mind
