Why Is a Little Dead Soldier Fighting in the Central Plains?

Liu Su traveled through time and became a pawn who died in battle. On the day the city was broken, the northern captives massacred the city for three days. He opened his eyes among the corpses. In his previous life, he was a special forces soldier who spent thirty years crawling among the dead. Now it is an unknown corpse under the wall of the border city. The "irregular system" was activated while cursing... The triggering conditions are unknown... The reward is unknown... From a low-level pawn to a evil star that makes Beidi people frightened. From following the idiot brother to find someone who stutters, to sitting on the chair competing in the world. At first he just wanted to survive tonight. Later, when he stood at the highest point and looked down, he discovered—— This world is already rotten. Someone has to clean it up.
