I Can Extract Murderous Energy

On the second day after traveling back in time, Lin Pingzhi was bound to the strongest murderous aura system. No matter how powerful the enemy is, don't panic. I will extract the murderous aura from him first, exchange it for training resources, and enhance my own strength before fighting again! It doesn't matter if you can't win. You no longer have the murderous aura in you, so there's nothing you can do to me.
