Lin Chen dreams of an eight-year apocalypse brought on by extreme heat. After waking up, his younger brother, Lin Hao, uses 10 million to trick him into handing over the jade pendant left behind by their father, believing it can be exchanged for supplies. But Lin Hao doesn't know that the pendant recognizes neither money nor gold. It responds only to sincere acts of kindness. Lin Chen settles in an abandoned industrial complex, builds an iron fortress, and stockpiles supplies. Meanwhile, Lin Hao pockets donations from his followers and spends recklessly. Eventually, his supplies run out, the pendant remains unresponsive, and he has nowhere else to turn but to his brother. Together, the brothers rescue disaster victims and work with the authorities to eliminate the violent gang known as the Anshen Society. Lin Hao transforms from a selfish, vain man into someone who learns responsibility, and the pendant finally lights up. Eight years later, when the extreme heat ends, the brothers reconcile and each begins a new chapter.
