Rebirth in the end times: I reached the top by opening boxes

Jiang Xiaoyong was betrayed and killed by a green tea girl in the apocalypse, but was accidentally resurrected a year ago and obtained the blind box system. He was always one step ahead of others, collecting supplies and spending a fortune to build a safe house before the apocalypse. He became stronger through the system and avenged his enemies in his previous life. From then on, he embarked on the road to the king's counterattack.
