after that the device and prime search for the key of the safe around the palace, while the three brothers search for the key around the library.
for hours they searched for the key, but still did not produce results...
finally they took a break and discussed the matter about the undiscovered key
"no matter what, if we do not quickly find the key we will not know the weakness sei.." said prime.
"there must be something." said the device while thinking.
soon enough, the device realized that he had found a clue to find the key...
"oh yeah, I remember now..."
"prime, you remember yesterday king Leon said what to us before we went here." said the device.
"yes.." said prime curiously
"king Leon said I'd tell you a temporary plan for you, find 3087." said prime.
"well maybe the number 3087 is the code to find the key." said the device.
"do you know where???" kia
"just a strong feeling about this." said the device.
"then we have to start from where." said prime.
after that the device takes the writing equipment to start writing something...
the device immediately went around the kingdom and looked for interesting things from there...
in the evening, prime and the three brothers fall asleep in the library room, while the device is still busy to decode it.
while reading a history book entitled king of the kingdom of rexus, the device finds interesting things in the biography of king leon...
king Leon was born on the 30th of 8th of 387.
device realized that the code referred to King Leon's date of birth...
the next day, Prime asked if the device had found any clues...
"how, any leads?" ask prime
"that's it, but this is still not entirely true or not..."
"but I seem to know how to unlock the contents of the clue..."
"we need to know what the date is, the month and the year." said the device.
"why do you need to know that." said Lia.
"and also I wonder, why in the book there is a year name, but here I do not find any calendar." said the device.
suddenly I realized something that he had entered a room full of strange numbers...
"oh yes I remember, yesterday when I wanted to find the key to open the safe I found a room containing strange writings and strange numbers..."
"where is that???" ask device
after that we immediately show the room in question...
the room was underground so it made the others except Lia feel unfamiliar with this path...
after a long walk, they finally found the room in question...
but the room had a big door with a strange pattern and the order to enter the code...
"hmmm there is a code, how to enter the code is also unique, there are 4 numbers and must be arranged accordingly." said the device.
"ah, maybe the code is 3087." said prime.
"maybe, I tried to enter.." said the device.
after that the device entered the code and managed to open the door...
after that they entered the room, and how shocked the device and prime because they saw a digital calendar in the room, not only that they also found a constellation...
"what is this!!!" say device with surprise
"why is something wrong, why is there a hologram there plus there is a constellation..."
"we have discussed it later. Now the hologram calendar points to the 28th of the month 8 of the year 411..."
"BEhold, THERE'S A KEY IN THE HOLOGRAM TRANSMITTER." said prime.
"maybe, you're smart, too..."
"all right, I take it..."
after the device retrieves the hologram transmitter, the calendar turns on now dead...
"just to explain first what a hologram is, and a constellation???" ask three brothers
"later I'll explain but we have to open the safe right now." said the device.
they run to the library and want to open the safe to find out the secret about the truth
SERIATE.
