My Number One Killer, I Forcefully Kissed the Underworld's Daughter at the Beginning

[Time Travel + Family + Single Female Protagonist + Relaxed and Funny + Daily Life] The world's top killer Jiang Cheng was stabbed to death by his brother in the back during a mission, and passed through the body of a person with the same name as him in his previous life. Good news: all the skills I had during my lifetime are still there Bad news: This predecessor confessed his love to the daughter of a gang boss at the beginning, and was beaten up by the other party. Can Jiangcheng who traveled through time endure this? In order to regain face, he directly kissed the other party forcefully. The reason was that after my predecessor's drunken Truth or Dare failed, I was asked to confess to a girl in the class. By coincidence, I confessed to Su Qi. I thought that the usually aloof Su Qi would refuse directly, but I didn't expect that the other girl accepted it happily. Jiang Cheng: Classmate Su Qi, I have liked you for a long time. Can you accept my confession? Su Qi: Okay, let's go out and talk tonight Jiangcheng: Talk? How to talk? Su Qi: Hehe, of course we can talk with fists and feet Su Qi's family: What, you dare to confess to my Qiqi and let him see what the underworld is! So the story of a young man and a group of gangsters began. I thought it was a crushing battle without any suspense. As a result, the strength Jiang Cheng showed shocked them time and time again! Su family bodyguard: Damn it, this guy is a humanoid tank, he is no match for the ten of us. The number one killer of the Su family: I have never seen such a powerful person! Equipment expert: The skills I have trained for decades are actually regarded as childish by him! Everyone in the Su family who learned about Jiangcheng's strength: What is this guy's background? Check it out for me quickly! Su Qi: I thought I hid myself deeply enough, but I didn't expect Jiang Cheng to hide it deeper than me!
