Outside the Alchemy Society, the royal guards had surrounded the entire building. There was also an endless stream of royal guards coming to support them.
One of the royal guards seemed to have noticed a black dot in the sky.
He rubbed his eyes and looked up into the sky. He whispered to his companion, "Hey, look, what's that?"
The other companion rubbed his eyes and said in surprise, "Are they bats?"
They didn't see clearly where the bat came from, but they vaguely saw the bat slowly fly into the sky and then disappear into the dark night.
"Did it fly into the building?"
"It can't be. You must be mistaken."
"No, I'm sure I'm not mistaken. I'll go find the Captain."
Fang Heng flew in through the window on the eighth floor of the building of the Alchemy Society. He returned to the storage room immediately after he returned to his human form.
