Mistaking My Sister-In-Law for My Wife After Getting Drunk! - Chapter 297 - It Really Has Nothing to Do with Me

A young Japanese man inherits his parents' grape farm after they impulsively bought it during retirement but couldn't handle its physical demands. Though initially reluctant, he finds success farming for three years until market oversaturation causes prices to plummet. While playing a new video game called “Immortal Order: Origin” about historical secrets, he is mysteriously transported to 16th century North America, where he encounters starving English colonists from the lost Roanoke Colony. His grape farm has been transported with him, complete with modern equipment and a secret gift called 'Immortal'.

Because of his master’s wine, he had somehow become the husband of a cold CEO — I’m still a virgin, please be gentle. He was from an ancient sect and had both Buddhism and Dao cultivation methods. The youth Qin Wu stepped out of the great mountain once again, stirring up the winds and clouds in the city.

Sequel of Allison, taking place about 17 years after the original series.

To save the hopeless Dark Fantasy World, I held back my tears and destroyed the world, then killed the Demon King and returned.

Now, I’m trying to save the world using the ‘System’ I gained as the ‘Regressor’s Privilege’… but the Main Heroines have also awakened their memories of the previous timeline.

God damnit.
