Gu Ze, the mercenary king of the 21st century, was forced by the organization to perform a mission in Bermuda. After completion, he would be free. However, he was assassinated and killed by his teammates. Once he traveled back in time to the 1980s, he became the adopted son of a city buyer who was a punching bag. When his biological son came to visit him, he immediately turned against him and took advantage of his upbringing to force him to transfer his job. The adoptive father's eyes were cold, "We have raised you for twenty years. You have replaced our biological son and lived a good life in the city. It's time to give everything back to my son, including the job assigned by the school."
