I Started as a Soldier and Sent My Wife to the Army, and I Activated the Beheading System.

Traveling back in time to ancient times, other people ran away because they were soldiers and lost their wives. I activated the system and picked a potential stock first. Others worked hard to practice martial arts and kill enemies to gain military merit and wanted to be a general. I killed enemies and became stronger and could summon thousands of troops. Isn't it the pinnacle of my life to dominate the world?
