Naruto: The Outsider's Resolve - Chapter 2.6 (037):

Song Xuanhe transmigrated into a book called “The President’s Seven Boyfriends”. He became the President’s cannon fodder ex-boyfriend, Song Xuanhe.

The Song Xuanhe in the book: 180 cm tall, so attractive he would trump over even the hottest celebrities, three generations of family in business–a very appropriate rich third generation.

It wasn’t a loss to transmigrate into this kind of person. It was just that this was a rebirth story.

The Song Xuanhe in the book abused the male lead 800 times and had even indirectly caused the male lead’s death. Faced with the reborn blackened male lead, his fate was obvious–not only did he reach rock bottom, he even died without an intact corpse.

Right now, he had become the cannon fodder ex-boyfriend that was foreordained to die without an intact corpse.

——

System: Don’t you think that the male lead has been a bit strange recently? It’s like he’s plotting something in the dark.

Song Xuanhe: Plotting how to kill me?

System: No, plotting how to eat you.

——

Song Xuanhe, who was lying on the bed with an aching waist, pained back and legs suffering from cramps, cursed the System 800 times–what happened to the male lead being a shou?!

Emphasis: Xiao Yuanmu is the gong! Xiao Yuanmu is the gong! Xiao Yuanmu is the gong! Moreover, the tycoon has always been a gong! Spoilers only up to here!

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.
