Time Merchant: I Sell My Lifespan at the End of the World

Civilization collapses. I awakened a special ability - trading "lifespan". While others struggled to survive in the ruins, I exchanged my days for fortresses, weapons, and even the loyalty of others. Until I rescued the coordinator Chu Feng in the research institute, and then became involved in a battle about the "origin of time". As all the forces bared their fangs, I discovered that every second of life I dealt with was linked to a huge conspiracy that could restart or destroy the world. In this ultimate bet where time is the bargaining chip, I have to do more than just buy and sell. I want to rewrite the rules for this hopeless wasteland.
