In the same place where Xin just take Tree of Knowledge, he uses Earth Magic to make a huge wall it was half the size of Tree of Knowledge.
After that, he uses Hardening Magic and Diamond magic to make the most durable wall in history.
Then he takes out his leftover paint and giant brush from last time, and he starts to make a large painting.
What Xin going to do?
Simple Xin want to leave a mark of the phantom theft on this Island as a simple of his glorious job.
Xin want the marine to think that he rob the huge Tree of Knowledge and the book inside of it, as for the archeology and scholar he just going to leave a message that he takes all of them to become slaves in a faraway kingdom.
Robin snap out and see that Xin doing something again, she was curious so she walked inside of the Illusion Magic to see what he doing this time.
Inside of the Illusion Magic she see Xin making a big painting out of huge Earth Wall, she knows that he needs lots of time to finish his work so he Robin just walk side and watch Xin doing.
Then Xin draw a huge shield in the middle with gold paint then a bright color red paint to draw a giant bird with wings spread in the sky and about to fly, a.silver colored ribbon to its claw with runes engraved on it.
He added some fern leaves on its beak orange color cloud for the background.
Xin make a huge bronze sword and silver Halberd on the back of the shield and in the bottom of it there a rectangular box where Xin writes the name of his family.
He engraved his family name into a Chinese character so they can't find him easily.
Robin suddenly asks," What kind of ancient letter is that Xin?"
Xin said," That is not an ancient letter that is my family name,Fei it means to fly ~.
"Isn't it cool ~!?"
Robin doesn't know that there's meaning on his surname, but she thought it was cool," Yes it's cool"
Xin then use Nullification Magic, Reflector Magic, Adamantine Barrier, and Hexagon Barrier Magic on it so that it will become indestructible.
He left a Meteor Eating Beast Core inside of the wall that he made to use as a power source,so even though he's gone the magic is still going to activate on its own.
After that Xin use grand magic, Element Change Magic for the whole island.
He combines Earth Magic, Adamantine Magic, Hardening Magic, and Metal Magic to make all the things on the island as taught as his painting.
Even though the whole island looks normal in the eyes of everyone but in reality this island already become an indestructible island that even a war commences inside of it nothing will change.
After finishing all the things he needs to do, the only thing that he needs to do is to wait for Robin's mother to arrive on this island before they leave.
Xin walk back in the ship to try if the system is working, Robin and him walk in the control room to try to fly this airship.
Robin asked," Are you sure that this thing can fly?"
Xin walk into the captain chair and sit, he said," Of course ~ just you wait and see how cool this ship are"
Xin then on the power source for the Floating System, Glide System, and Stealth System.
The indicator light turns to green means that all system is ready, then Xin activates the Floating System of the ship to levitate it away from the ground.
*Beep
*Shake
The whole ship starts to shake but not too much, just a little, everyone inside of it know that the ship is starting to move.
Xin then activates the surveillance System that he just install just now to see what happen outside.
Then he on the 12 monitors in front of him so that they both can see what is happening outside.
When the monitor turn on, both see that the ship is starting to float into the air.
Robin amaze in what she sees," So this ship really can fly"
"Of course this thing can fly, I designed to fly into the air," Xin said.
The airship start to float into the air higher and higher, the archaeology and scholar run to the windows to see wah happening.
They all see the vast see outside of the window while the Ohara island below them.
Clover emotional said," So this really can help us escape"
"That's right Profesor! Who thought that Kid is genius shipbuilder"
"And not only that this ship can mark as one of the successful flying ship in history that mankind made"
"What a good kid"
...…
While the archeology and scholar talking to each other, Xin and Robin try the other system's ability of the ship.
Xin activates the Stealth System to make it invisible to others,he doesn't want to attract attention because of this.
He turned on the Stealth System and the lite on the system controller turn blue it means it was already activated.
Outside the ship starts to transparent not that instant invisible but slowly.
It takes a few minutes to make the whole ship invisible, but it was not a problem for Xin he can upgrade all the systems later after he goes back to Sorami Island.
After that Xin activates the standby mode and let the ship float above Ohara Town and while waiting for Robin's Mother.
While waiting XIn start to finish the work that he left.
Like painting the rooms and other facilities.
He even forgot to build the water system of the ship and electric system for lighting and the mess hall if they want to eat.
Overall he need to do lots more things before he can say that the ship is already done.
