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.

A civil engineer reincarnated into a magical land and tragically became a Wood, Earth, and Water Sorcerer.While still questioning where his [Earth Bear Bloodline] originated, the Chosen One next door summoned a 'player'...Watching others lead extraordinary lives, Hill just wanted to hide away.

[Space + Farming + Escape from Famine] The apocalyptic boss Bai Wutong took Space World to ancient times, and before he was happy, he found himself in a troubled era of escape!

Murder and robbery, making money and killing people, the price of sitting on the ground can be found everywhere.

Come up, she will kill two people.

She was kind enough to save someone, but she was deceived, stalked, and insisted on following her.

If that’s the case, don’t blame her for being jealous.

After finally settling down, he was assigned to the frontier to open up wasteland.

The sky is high, the emperor is far away, the fast piston is immortal, and Bai Wutong can’t ask for it.

Several years passed.

Bai Wutong accidentally led the richest man of the previous dynasty, the prime minister, the commander of the dark guard camp, the contemporary great Confucianism, the female saint, the magical doctor… and turned the barren land into a rich and noble town that everyone is craving.

The emperor came here with his ministers admiringly, looked at it, and was dumbfounded.

Isn’t the man who poured tea and water beside Bai Wutong the eldest son who has been dead for several years?
