Xu Liang was originally a cultivator who accidentally returned to his boyhood after failing to overcome the tribulation. However, he was surprised to find that the world he was in now was completely different from the world in his previous life. He didn't even have much family ties with his parents. He was originally a civil engineering major, but now he has become an intern in the security team at a security university. Fortunately, the skills he remembered in his previous life and the spiritual consciousness he cultivated have been preserved. After a month of internship, at Xu Liang's repeated request, Xia Min, the captain of the Second Public Security Team, agreed to his participation in a driver's collision case. However, after Xu Liang's careful observation and some attempts in his previous life, he concluded that the driver who surrendered was to help his son take the blame, and used some tricks to make his son confess in public and admit responsibility for his negligence. Through the case of the driver who caused the accident, team leader Song Guo saw Xu Liang's potential and took him to solve another murder case. Using the powerful search function of his spiritual consciousness, coupled with the professional characteristics of the deceased, and making bold assumptions, Xu Liang quickly deduced that the murderer was the deceased's wife. At the celebration banquet, a woman who claimed that her younger brother was wrongly accused suddenly appeared. Under the other party's various tricks, Xu Liang was invited by Zhang Yang, the leader of another group, to go and have a look. When Xu Liang learned what happened, he soon discovered that the victim was indeed not unjust. Using a clever trick, he immediately broke through one of the suspects' psychological defenses and confessed. The capture of fugitive Cheng Long leads to an old case.
