He found out that he is in a world similar to our own with a timeline akin to early twentieth century.

Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout.

Reincarnated into his college days. Zhou Yuwen knew the importance of a persona. In this life, Zhou Yuwen’s labels were aloof, mature, and exceptionally talented! “I’m quite traditional, I believe that if you’re in a relationship, you need to be responsible, so one must be extremely cautious about dating.” “Zhou Yuwen, let’s get remarried!” “Damn it! Are you poisoned or something? I haven’t even been married before!” “Stop talking nonsense! We were married in our last life!” “That was in the past life!” “Remarry!” “Go away! I have a girlfriend!” He fled, she chased! He couldn’t escape, even if he had wings!

When the pure lotus provoked her, she slapped her instantly, “It's just a pair of worn-out shoes. If you want them so desperately, take them and wear them.”President Jones intruded with a cheeky face, “Wife, even if they're worn-out shoes, I'd only let you wear them.”“Scram!”...【One man, one woman】Four years ago, she left in fury with the bun in her oven. Four years later—“Uncle, I noticed that your face has a gloomy look, it looks like you have excessive liver heat. It's obvious you lack a wife. Do you want to get to know my mommy?”The president who remained aloof from women looking at his mini-me, his eyes deepened.
