Reincarnation Of The Businesswoman At School (WN) - Chapter 99: The First to Hand Paper in the Monthly Test

In the Solarian Empire, people were divided by their blood. The nobles enjoyed their life in wealth, with fine wine and amazing food. They reigned supreme over the commoners. The only reason they were able to do this was that they had knowledge of the most powerful force in the world - magic. The nobles controlled their knowledge from easily going to commoners, making it harder for them to learn magic.

Leo, a young orphan in Solaria, had an incredibly powerful affinity for magic. He didn't even know about it because he could never learn magic- he was too poor to try and learn from any magic academies. He was just trying to survive the streets of Solhaven until he found the lost tome of the Arcane Emperor.

"I can beat a 7th Circle Mage."

"Wow! You must have trained for many decades. How old are you?"

"17."

The world was going to be turned upside down.

Once through the pirates, Lu En became the son of Monkey d Dragon, a grandfather named Monkey d Karp, and an unreliable and neurotic younger brother named Luffy.

Fortunately, the ghost back system is activated!

The completion of the ghost back is 10%, and the training effect is increased by 100 times!

One day, Lu En, a ghost-backed master, appeared in front of Luffy who was shouting to go to sea, and made Luffy cry on the spot.

Luffy: “The pirates in the sea are all monsters like my brother? I don’t want to go out to sea!”

Garp: “For a long time, the two boys, Long and Luffy, with small arms and calves, I really doubt that they are not my sons and grandsons. Like Lu En, they are the grandsons of the old man!”

Warring States: “The strongest creature in the sea, land and air is Kaido? No, it’s Lu En!”

You thought being reincarnated as an extra-side character was bad? Imagine being thrown into the body of a villain who is disowned by his own family and discarded by the author.

Long Fei, a cross-timer and doujin, is an otaku who traveled to another world. In the original world, he was an otaku fan of Gundam and military science fiction.

He died in an accident and was reincarnated into another world. The Gundam works he had read before his death and the techniques in various military novels could be brought to another world.

How would he use the Gundam that Long Fei created? What waves can be caused in this different world?
