After calling out for a long time, the fat guy realized there was no response. Well, he actually hadn't expected any. He wasn't Nobita, and broadcasting wasn't Doraemon. It wasn't like shouting "broadcast" would make a bamboo-copter fly over to help out in a situation.
However, this Formation was really giving the fat guy a headache!
The Formation in front of him was very simple, very basic, but every stroke, every line, even every detail was perfectly natural. The fat guy even found himself unable to spot a single flaw.
Solving a Formation was actually a contest between the understanding and skills in Formation of the one who laid it out and the one trying to break it— it was like a battle of wits between a tomb builder and a tomb raider.
