Where Are We?

The old man agreed to Seiji and Tanaka's wish , so the old man let them stay in a room. "Man, this such a stress" said Tanaka, "I know right we are having fun then, suddenly we were struck by lighting, and here we are" followed by Seiji. The next day the old man sent the boys to their destination. "Where are we" Seiji ask "I don't know" said Tanaka. Then the old man used telepathy and said this the world, Thrae a vast world full magic, mythical creatures, dungeons, and more. As they explore the world, they realize they are in a cave, luckily slimes don't need to eat, so food is out of the way for the two of them. Seiji said to Tanaka "Tanaka let's train and find a way to get out" Tanaka followed and said "Yes, I'll train with my unique skill then you use your unique skill when I knocked the enemy." Seiji was happy with Tanaka's idea. As they explore the cave they met their first enemy which is a Tarrasque which is a vicious creature which have a lion for its body, a snake for its tail, and a creature of some kind for the head. "Wind Assault" exclaimed by Tanaka then fainting the Tarrasque then, "Chimera Absorption!" Seiji said angrily then suddenly, Seiji heard a voice from the Great Sage Skills for Tarrasque, Transform: Tarrasque, Epicenter, Earthform, and Camouflage.
