I Got Lucky as Hell

Guo Jun's IOU-fueled life began with a top-secret government document.

[Received on loan: one metric ton of military yellowcake uranium. Borrower: Guo Jun. Purpose: Cultivate immortality and break through a cultivation bottleneck. Promise to repay: one hundred times the amount borrowed.]

While nations around the world hunted him for the missing nuclear material, Guo Jun was on the far side of the moon, measuring the depth of a crater with his fist.

Later, an alien fleet arrived at the solar system's doorstep, throwing the world into a panic.

China's Space Force lined up to meet the enemy. On the flagship's window, a new digital IOU slowly appeared:

[Received on loan: one alien capital ship. Promise: After analyzing its technology, repay humanity a thousandfold.]

From an electrician on Earth to an interstellar creditor, Guo Jun used a single IOU to shake the entire universe.

"They say cultivating immortality means defying heaven. Me, I'm just used to writing the country an IOU."
