Magic Box

Shen Yifu, Fatty and Erwa, high school classmates who became friends through games in the past, drifted apart after being admitted to different universities. After work, while participating in the development of the strong artificial intelligence project - "Jianmu Project", Shen Yifu reunited with Fatty as competitors, and learned from Fatty that his second baby died unexpectedly. Erwa left himself a mysterious relic - the magic box through his will. Shen Yifu discovered that the second baby had left a puzzle that showed that the second baby's death was closely related to the fat man. Fatty also continued to help Shen Yifu solve the mystery and inquired about Shen Yifu's company's bidding status for the "Building Plan". Is this a reminiscence of past friendship? Or a ruthless business war? Or is it a punishment from God?
