A special military doctor traveled back in time to ancient times. Right after arriving, she married the great hero of history, Mo Jiuye, in a wedding ceremony.

According to historical records, the Mo family was filled with loyal heroes, yet they were feared by the Emperor for their great achievements, and the day after the wedding, the entire Mo family was exiled.

Knowing this history, He Zhiran decisively used her space abilities to move all the Mo family’s belongings away before the imperial troops arrived to confiscate them.

Before being exiled, she also saved the lives of the entire Mo family.

Worried they might starve to death on the exile journey? That’s impossible, He Zhiran not only had enough supplies in her space, she also possessed countless money-making skills.

Along the way, her eight sisters-in-law regarded her as an idol and followed her every instruction.

Her mother-in-law and aunt secretly supported her – if anyone dared say anything bad about He Zhiran, they would tear that person’s mouth apart.

Finally settling down, their days became better and better.

Mo Jiuye said: “Wife, we’ve been married so long but still haven’t consummated our marriage!”

He Zhiran replied: “If you want to consummate, you’ll have to prove yourself first.”

Mo Jiuye swore: “I vow to the heavens, you’re the only woman in my heart in this lifetime, no, in the next lifetime and the one after too!”

He Zhiran said: “You have to keep your word…”

Such bullshit!

Elves in addition to beast race, dwarfs and demon race. Even though I wanted to make a harem in the different world I saved! My dream will not come true on earth, where there is no magic at all. Thus, the hero returns on his own. Without the blunder of being extradited to earth this time, he will build a harem of his own in a different world.

“She was originally a demon. How could she be led evil after meeting a human like me? Those critics always say some ridiculous things.”

In 1798, during an interview with a reporter, Cardinal Ranchi was asked about his past with the exiled princess of the last descendant of the Demon Clan and the recent signs of the Demon Clan’s recovery. He said:

“I have made too many efforts to safeguard world peace. I am convinced that under her leadership, there will be no chance of the demons returning to the country.”

…

In the winter of 1802, the demons successfully restored their country.
