Number 18, named Zheng Qihe, was an executive at a local construction company. Despite his excellent academic performance from a young age, his personality had always been extreme because his mother had abandoned him and his father when he was three years old.
During college, he encountered the concept of "purity" and became increasingly obsessed with it. Two years after graduation, he joined the Digital Group as Number 18.
That was over twenty years ago.
Since then, the Digital Group had been lying in wait. All its members believed Zero's words that "purity" required the right moment. Although they took no action, all members of the Digital Group were secretly preparing.
For example, a few years ago, after his company undertook the research institute's construction project, Number 18 used his authority to clandestinely build an underground space there, hiding one of the Digital Group's labs inside it.
