But Roland had just watched the fun.

If you go to the real world, you can understand the principle at a glance.

After walking for another half an hour, Roland turned to the second floor. It was much quieter and in a long corridor, there would be a black door every five meters.

Roland took Andonara over and found a room with 1002 written on it, and put the blue wooden sign on the lock.

The door is open.

"When did you break the secret of this wooden sign?"

Andonara was a little surprised.

She never doubted Roland's intelligence, and knew that he would definitely be able to unlock it.

But along the way, Roland seemed to be watching the fun and didn't even look at the sign.

"When you get it, you will know it's roughly." Roland pointed to the blue sign and explained: "These dots are different in size. There are six, which you see as hexadecimal numbers. Then these lines are actually simple to use the map of the channel, with numbers and maps. Just compare them on the road and you will know where our room is."

Andonara's eyes widened: "What is hexadecimal?"

Well... Roland scratched his head and explained what hexadecimal is to a semi-illiterate person. It seemed to be a bit difficult.

At this time, the door next to them opened.

From there, a female magician came out.

Blonde hair and blue eyes, tall and tall.

The hair is a little short, just the level of the shawl.

She glanced at Roland, was stunned for a moment, then bent down and saluted slightly.

Because she could feel that Roland was better than her.

After the salute, the female magician was about to leave, but she took two steps and suddenly turned back.

Looking at Andonara: "I've seen you!"
