Delivering express on a rainy night, Director Chen accidentally got involved in a bloody treasure hunt. A USB flash drive turned out to be the core key of "Base Zero" that he had sealed three years ago! I wanted to live an ordinary life anonymously, but I was targeted by Blue Whale Capital because of this key. Ma Bao's young boss Lin Zhihao arrogantly grabbed the goods, but was knocked down by him; the cool female president Lin Wanqing hid another key and plotted to restart the "Ancestor Project". What's even more frightening is that the international criminal group "Ghost Organization" has surfaced, with modified human warriors, genetic experiments, underground arsenals... The peaceful life is completely shattered! Director Chen had to put on his uniform again and use the multiple vests of courier, logistics consultant, and "cyber security expert" to deal with various forces. This time, he not only has to protect the base, but also uncover the shocking truth that he was chosen to be the "successor"!
