Lu Wu, the evil god who used to be able to frighten the three realms with his tiger roar, is now worried about the three-digit balance on the ATM machine. The mythical beast egg in his arms that was about to hatch would require him to drink half a month's salary of "imported spiritual liquid" every day. In order to earn money for milk powder, he disguised himself as a retired soldier and joined a top consortium as a security guard, but unexpectedly became the personal bodyguard of CEO Gu Yanzhou. This ruthless boss with an emotional disorder launched a "captive" campaign against him that he could not refuse. While Lu Wu was scrambling to hide the shocking origins of himself and Dan, and learn the human parenting guide, he also had to deal with the boss's increasingly dangerous approach. Until the pursuers arrived, he was forced to reveal his shattered true body, protecting Gu Yanzhou behind him, with a hoarse voice: "Did you scare me? It's too late to run now." But Gu Yanzhou wiped the blood on the corner of his mouth, with paranoid and burning eyes: "Run? I want you and the little trouble in your arms." - The most vicious god in the three realms, why does he always study "Encyclopedia of Parenting" late at night? Why is the ruthless boss obsessed with hoarding exorbitantly priced milk powder for unknown creatures? It all starts with an egg.
