The youngest, silly fourteenth son of the Yan Emperor had reached the age where he should be given a separated territory now. He rejected the wealthy land, neighbouring the capital city, and instead chose the wildest land in the western region— Liangcheng. Everyone shook their heads and sighed. A fool is indeed a fool. If you go to Liangcheng, you will be killed by barbarians in less than three to five years.

One year later, the watermelon presented to the Emperor as the tribute from Liangcheng in the west was sweet and crispy. There was no one in the palace who did not love it.

Two years later, Liangcheng presented corn as a tribute to the Emperor. The yield was high, and the taste was good. No one in the country could resist liking it.

Three years later, Liangcheng defeated the barbarians and presented their prisoners in front of the imperial court. The people of Yan were excited and their morale was greatly boosted.

Four years later… Everyone said that the fourteenth prince Mingyu was a fool, while the little fatty Yu, who transmigrated with the golden finger, chuckled. Let’s see how you guys look at this fool build his own territory, then.

Eluard Kai found himself transmigrated to a magical world.

A steward came over and declared that he was now the academy master of the school in front of him before disappearing to nothingness.

“That damn steward said I am now the owner of this place then left me all alone! What the hell am I supposed to teach them anyway?!”

He feared that some prodigious arrogant young master would come over and enroll when he himself didn’t know what he was supposed to do.

“But this is a deserted academy, right? No one should come over here, right?”

Unfortunately, his nightmare came about.

“Academy Master, I am here to enroll in the Heavenly Magic Academy. Please allow my request in behalf of my lackluster talent.”

Eluard Kai almost blacked out until he heard a prompt in his head.

[ A student requests to enter the Heavenly Magic Academy. ]

[ Accept the request? ]

“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.

[Based on the above materials, please identify who is the main war criminal who led to the return of the demons, and explain why it is Lan Qi. (10 points)】
