Terror Resurrection Unlimited Upgrades

Terror has descended and hundreds of ghosts are rampant. At this time, only by binding a powerful system can we survive. And it would be even better if he could keep upgrading. He is half ghost and half god, like a ghost and a god. When mortals are still struggling for survival, he is already strong enough to protect the safety of a party... Only when you are strong can you be truly powerful! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
