One Piece: God of Space - Chapter 398 New Navy

Xiao Yijing returned to the real world from a narrow escape from the infinite world, and got the reward from the system – a group of unfinished buildings!

Although the unfinished building is in dilapidated condition and a lot of waste is waiting to be done, Xiao Yijing resolutely chooses to put it in ruins. Whoever likes to get a job will get a job, anyway, I won’t get a job!

When I have time to grow vegetables, raise chickens, herd cattle, and feed pigs, my small life is very nourishing.

Eh? Let me expand the scale of farming? ——No, it’s too troublesome!

What? Want to live here? ——Yes, you can settle the house by yourself.

ha? Do you want to help with work? ——Okay, you can handle it yourself!

By the time Xiao Yijing came back to her senses, the people who worked at their own expense had already gone to the sky, and the unfinished building was unknowingly revived!

(There is a male protagonist, but there are very few emotional scenes)

In chaotic times, one seeks survival; in prosperous times, one seeks fame.Despite being weathered by the vicissitudes of life, the Great Yu Dynasty still found itself in an era of prosperity.In the northwest, a youth trekked nine thousand miles on foot, slaying the Great Demon alone to compete for a lifetime of glory.In Long Lake, an unmatched Grandmaster hurried to the mortal realm to establish a sect, leaving his name to be revered for a hundred generations.In the imperial capital, a saintly figure spread his teachings far and wide, with followers throughout Qingzhou, his legacy lasting forever.Yet within Qingzhou City, in the compound of a family with a long military heritage,there was a child who never engaged in serious pursuits, instead spending his days playing chess, painting, fishing, and playing the zither.Years later—……When the sword rose, dragon smoke stretched for three thousand miles, and a single strike wiped out the cities of nine provinces!Among all the laws of the world, only I, have entered the path.
