Guarding the Border and Dying Tens of Thousands of Times, I Am Invincible

Once reborn, Su Cheng became a soldier on the battlefield of all races. An accidental death awakened the "death and rebirth system". Each different death will result in different rewards. If you die by self-destruction, you will be rewarded with the remaining copy of the heaven-level skill. Being killed by a strong person in the Golden Core stage will reward you with cultivation in the Golden Core stage. After countless deaths and the battle of all races ended, Su Cheng suddenly found that he was invincible now!
