System Crisis Record

The killer went on a mission and died accidentally. But it relieved a grudge in her heart - her real name was not Shen (3) Lu (6). After getting rid of this name, would she be qualified to get close to that person? But she died. But a strange guy came out and said, "I'll send you back, and you can do some research for me." Shen Lu rolled his eyes. He didn't want the opportunity to see his sweetheart again in vain: "Okay." But I didn't expect that this research would last for nearly a thousand years, and eventually lead to a murder case separated by time and space.
