MTL - Hello, Mr. Major General - Chapter 12 What evidence

At eighteen years old, Lin Qingyu was married as part of a Chong Xi into the Nan’an Hou Mansion, becoming the ill Lu Wancheng’s male wife.

On the eve of their wedding, Young Master Hou lay lazily on the bed and said, “Beauty, to be honest, I really don’t want to engage in domestic struggles. I just want to drift along, eat and wait to die. I want to be a salted fish.”

A year later, Young Master Hou became gravely ill. He took Lin Qingyu’s hand and sighed, “Wife, I’m going to die, but I think I can continue to transmigrate. In order for you to properly recognize me in the future, let us set a secret code.”

After the death of Young Master Hou, Lin Qingyu was prepared to stay a widow all his life. Unexpectedly, after only half a year, the great general who had rendered outstanding military service, actually came to propose marriage.

Lin Qingyu would rather die. But the general said but one statement, “If odd, change; if even, remain the same?”

Lin Qingyu: “…I will marry you.”

After two years, the general died in battle. Before Lin Qingyu even had time to grieve, he was recruited into the palace by the Emperor.

The emperor complained aggrievedly, “Baobei, this time I have became the Emperor. My salted fish dreams have been completely shattered…”

Lin Qingyu knew that although his husband was a bag of lazybones, no one was his equal when it came to conspiracy and schemes.

He rubbed the Emperor’s head. “Don’t think about it. Get started on those reports. Behave yourself.”

This legend tells the tale of the protagonist, Kuroki summoned to protect the demon king from the hero.

Kuroki, unbeknownst to him, suddenly came to another world. He was summoned by the demon king, Modes. The territory which the demon king overrules was in the midst of being destroyed because of the hero. He had no choice but to bow before Kuroki.

“Please save us, Savior Dono!”

Kuroki nodded, deciding to save the demon king due to an unexpected turn of event.

Xiao Yu, who was a student from modern Earth, accidentally transports to another world and becomes the lord of a territory. Facing an unfavorable situation, he vows to take back his family business, build his new territory, kill all of those who covet his wealth, and dominate the world!
