In 2079, global temperatures suddenly increased, causing desertification around the world. Natural disaster strikes. The virus studied by country M was leaked due to man-made reasons, and the virus quickly spread around the world. The terrible virus crisis comes with natural disasters. Only 1/10 of humanity survived after that natural and man-made disaster. For this reason, the remaining humans built human bases, but they did not find peace. The advent of natural disasters kept the temperature at 60°C and above every day, and the viruses outside caused animals to mutate.

The good times didn't last long, but someone discovered the secret of the Fountain of Eternal Life... Legend has it that drinking the water from the Fountain of Eternal Life can lead to eternal life. Some humans began to break away from the human headquarters base and went outside to establish their own organizations. One of the largest and most vicious organizations is the most famous. This organization is called Zhenba, and the people in the organization are all heinous desperadoes. It is rumored that the founder of this organization wanted to obtain the spring water of eternal life.

Known as punishers, each team has 6 people, and their levels are divided into S-level, A-level, B-level, C-level and D-level. From d on up, the higher the level, the stronger the team. S-level teams usually do some missions with a high risk factor, and CD-level teams usually do some missions to find supplies and eliminate mutant animals outside the base... The fountain of eternal life tears apart the surface of human nature, revealing the rotten heart...
