Special Blueprint Requirements

"So, this is the Communication Room!" Elias' commented as he entered the lone building on Growing Isle. It wasn't anything special, the walls, the table, and the chair were all smooth white. 

He walked and sat on the office chair—surprisingly it was soft, it wasn't made of complete white stone. Seating down allowed the formed door to seal itself as if the door had never appeared.

Elias stared at the wall that the chair was facing. Now, he was facing—it was extremely smooth and reflective. 

[Would you like to Turn On the Communication room!]

The Pentagon flashed him the Notification.

"Yes!"

The wall he was now facing outlined a delicate shape of 100cm long and 200cm wide rectangular bright carving. 

Then it glowed slightly, and its light shone on the small office white stone table before Elias. Being lit, the table showed a design of Grade 4 Local Blueprint Island he just merged with.
