Gu Ji, a cadet at the SWAT Academy, downloads a game called Crisis Management. After he clicks it, he has been thrown into the game's world. After he beats an instance, the same event would happen in the real world.“Your Choice：Stamina Boost (Small)】or【Combat Specialization (Small)】”

Variable Name: An Wujiu
Attributes: Male, 20 years old
Game Rounds: 5
Win Rate: 100/100
Danger Rank: SSS

No wonder they were afraid.

It was until he saw the man had a sudden personality change. He recklessly gambled regardless of the cost, casually estranged people, grew further excited on the verge of death, and even calculated against himself to win. Only then did Shen Ti realize that it was his own cognitive bias.

Fortunately, he wasn’t a normal person either.
