Zhu Mang found the answer to this question when he dug out a book resembling a diary or memoir from somewhere within the Flower Room.
Perhaps Imu had lived too long and feared forgetting something.
Or perhaps it was merely a personal hobby.
Imu had written down quite a lot in the book.
And through it, Zhu Mang learned the truth about this world.
What shocked him was that Imu was not from this world!
No, more precisely, Imu was not a native of this planet!
Around two thousand years ago, the planet of Imu and several Celestial Dragon families suffered a catastrophic disaster. Left with no choice, they could only flee together aboard spaceships.
After a long journey through space, their ships malfunctioned nearby and made emergency landings on one of the pirate planet's moons.
After recovering for some time, they discovered that the nearby planet was actually habitable. They decided to conquer it and make it their second homeland.
However, the pirate planet had already given birth to nations such as Alabasta, Dressrosa, and Fish-Man Island.
Yet the true ruler of the planet was the Great Kingdom, founded by the Giants.
Although many of the Primordial Celestial Dragons' ships had been damaged during their journey through space, they still retained a great deal of advanced technology.
They had thought that even a tiny remnant of their "spacefaring civilization" technology would be more than enough to crush these natives.
Reality, however, dealt them a heavy blow.
The Great Kingdom's technology was not actually inferior. It was simply specialized in different areas.
They possessed several unique "secret treasures."
The Treasure Tree Adam, incomparably resilient and able to withstand even the ravages of war without falling.
The Sunlight Tree Eve, capable of transmitting sunlight directly to the seafloor through its roots
