My Wife is a Demon Queen

Xiang Ye was a fairly ordinary young man; after happening upon a ring he finds himself summoned to another world by members of the Demon Tribe, including their queen, Isabella Osa. In an attempt to save their lives from the human armies, Xiang Ye claims that the, now greatly weakened, Isabella is his wife, Yei Bi. Now both must try to get stronger to survive in The Capital of the Human Tribe territory.
