I Got Lucky

Guo Jun's life IOU started with a top-secret national document. [I borrowed today: military yellow cake, one ton. Borrower: Guo Jun. Purpose: Cultivation of immortality and breakthrough. Return promise: return it a hundred times. When countries around the world wanted him for missing nuclear materials, Guo Jun was on the back side of the moon, measuring the depth of the crater with his fist. Later, an alien fleet invaded the solar system, causing global panic. The Chinese Space Force lined up to face the enemy, and a new electronic IOU slowly unfolded on the flagship porthole: [I borrowed today: an alien battleship, a complete one. Commitment: After technical analysis, it will feed back to human civilization ten thousand times. From an electrician on earth to an interstellar creditor, Guo Jun moved the entire universe with a single IOU. ——"It is said that cultivating immortals is going against nature, but I am just used to writing IOUs to the country."
