That Time I got Reincarnated As A True Dragon

The castle is light

“ so how do you want to win this “ asked Rimuru as they reached the location that was supposed to be their base camp.
“…..My class is Castle Lord (Guardian) so   I’m good at  <Ibis>………” said Misha
The members of each teams  were divided into different classes to differentiate the the percentage of magic power one would receive after casting the spell. These classes were chosen by the students after conducting a test to see their capabilities and attributes . The classes are,
Demon King (King)
Castle Lord (Guardian)
Sorcerer (Mage)
Therapist (Healer)
Summoner (Summoner)
Demon Swordsman (Cavalier)
Shaman (Shaman)
Each class hold a very important roles in the formation. But all of them receive the passive magic power from the spell which the king  supplies.
“ hmm I’m a sorcerer and a demonic swordsman.” Answered Rimuru.
“ Hmm” Anos thought for a while and then he smiled evilly and said “ I have just the perfect strategy “
Looking at his smiling face Rimuru thought ‘ sigh his bad habit are beginning to  reappear again, well at least this would be fun anyways ‘

“Sasha-sama. Three castles have been built on the enemies side.” Said one of members that was  in charge of information gathering.
Looking at the huge castles that were identically created she deduced, “hmm , Two are probably traps. The Demon King (King) will be hidden in the remaining one.”
“Do we destroy the castles one by one?” asked One of her other teammates.
“No. In such a short time Misha cannot create three complete Demon King castles. She will be buying time to complete and strengthen the real one. I’ll swat them ….” She trailed off when a huge magic circle appeared in the sky engulfing both camps.
“ Give me report about that circle now “ shouted Sasha while cold sweat gathered on her forehead.
“ Sasha Sama it is area wide spell , although our Shaman and Sorcerer’s were unable to identify its real use , they deduced that it is a spell created change the environment. “ replied one hurriedly.
“ Tsk this is not good , I don’t like having this unknown magic circle here , all units gather near the castle I will go and destroy this spell. “  as Sasha was about to leave she interrupted again.
“ Sasha sama the enemy king Anos Voldigod has suddenly appeared in front of the castle! “ exclaimed one as he suddenly shouted.
“What!? How’d he do that…?” Sasha asked baffled.
“I don’t know. The Shamans were  watching very carefully for approaching magic power but he just suddenly appeared!! It’s some type of magic we don’t know!” said one of people who were in charge of data analysis.
Sasha took a deep breath to calm her mind. She then started to think of various possibilities, as a her background is special she knew some spells that were generally not available to be public.
“ No , it’s not a unknown spell, if my guess is correct it’s the lost spell <Gatom>. 
And I hope it really is “ she mumbled the last part quietly hiding her fears to clash with two unknown spells.
“Wow you really have good leadership skills “ said a unknown but familiar voice that made everyone shocked.
“What the…….. Why can I hear that guys voice!?,And how is he listening on to our conversations. ” shouted Sasha.
“I don’t know. The magic formation has no problems. He shouldn’t be able to tamper with our spells. ” said one of her officers  clearly flustered.
“Well, he can!! Find the cause, quickly!! There’s a chance that he was hearing all our conversations ”
“ Yare yare. You guys are too noisy. “ Anos said in a bored voice.
“ then don’t listen in on others conversations “ Sasha couldn’t help but retort.
“ well the way your team constructed the spell is way too amateurish. It’s like they are basically begging me to eavesdrop  on you guys. “ He said,
“ You bastard, that spell was constructed with a 90% chance of absolute concealment, even national secrets are only discussed in a 92% chance of  absolute concealment. “ said one of the members who helped in constructing the spell. That was their masterpiece damn it . He thought while almost crying tears of blood.
“…. Are the national secrets safe with that kind of low quality constructed spell “ Anos couldn’t help but ask.
At this moment everyone in Sasha’s group had one thought in mind and that is ‘ I want to strangle this bastard ‘
At this moment one of the people who were outside of the control room came running. Before he could speak Sasha stopped him with a raised hand . Then signaled him to come and speak to her directly.
After listening to the massage Sasha couldn’t help but shout in anger ,
“ Bastard do you look down us so much that you came to our base alone.
Men deploy every available personal to initiate a attack, don’t bother about the enemy king’s interference in our communication spells , make him pay for underestimating  Us . “
“ Yes Sasha sama “ shouted everyone in unison.
“ wow you guys sure put some effort into building this castle “ said Anos as in one of screen showed that he is already near the castle.
“ of course it is , This castle was constructed by 7 (Guardians). You won’t be able to breach even the first layer.” Said Sasha proudly.
“ oh 7 (Guardians) made this? I guess it will be pretty sturdy. There must be  a good  number of traps, dungeons, reinforcements for the (King) and plenty of protection.
However,  It’s a very light castle you know ” Anos said touching the castle directly without even batting a eye on the countless Anti-magic spells that covered the whole castle like a barrier .
“ You what are you doing” asked Sasha feeling a bad feeling.
Ignoring her Anos grasp the walls so tight that his fingers sank into them,
“If you are only cautious of magic then you don’t know what a real battle is So Remember this. In the future make your castle heavier.” Saying so he lifted the entire castle up from the ground.
“ impossible how is he doing this, as a king he doesn’t get any boosts from the spell. “
“Certainly, when using the power <Gyze> depends on the class, however, there’s a big difference between our base strengths.” Saying so he started to rotate the whole castle in one finger like a pro basketball player.
“ Kyaaaaaaaaaaaaaaaaa” shouted the people who holding to their dear life in the castle.
“Hey, take care when falling otherwise you’ll die.” Saying so he threw the now spinning castle in to someplace in the forest.
The castle landed on the ground and then ,
* boom *
