Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory?

Spend life energy to infuse martial arts, and you can perform unlimited deductions.

Shen Yi’s mortal body only has a lifespan of less than a hundred years. Fortunately, he can gain his remaining lifespan by killing demons.

In the troubled times where evil spirits are everywhere, the long sword is revealed, causing the liver and gallbladder of these creatures who have lived for thousands of years to burst!

From [Eagle Claw Technique] to [Eight Desolations Splitting Heavenly Hands], from [Demon Subduing Fist] to [Golden Body Prison Suppressing Dharma Appearance]!

Shen Yi occasionally ponders, how come this lifespan is getting longer with more use?

He put the sword into its sheath, raised his eyes to the sky, and heard that there was a Jade Palace above the clouds. It was filled with thousands of saints, each of whom had experienced endless years.

This time I came to heaven just to borrow a million years from the immortals to prove my path to immortality.

[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?
