A Guess

In the square hall, a skinny old man was sitting in front of a wall.

He stared at the alchemy formula drawn on the wall and fell into deep thought. The alchemy brush in his hand was placed in a corner, but he couldn't find a place to write.

Suddenly, the magic array on the ceiling of the hall flashed with a blinding light.

The old man frowned and put down the alchemy brush in his hand. He stood up and looked up at the center of the hall.

Then, Fang Heng and the others emerged from the alchemy magic array on the ceiling in the center of the hall and fell from the sky one after another.

Fang Heng realized that the teleportation had ended and quickly adjusted himself. 

As soon as he landed on the ground, Fang Heng quickly moved a few steps to the right before he could check his surroundings carefully.

"Bang! Bang Bang Bang!"
