He Must Be Very Loyal

Even though his brothers were still inside, he had to ensure his own safety first so he could keep them safe later on. If he was in danger, they would definitely risk their lives to protect him.

Just as Nangong Nuannuan had said, the tile looked no different from the other tiles. However, when he stepped on a stool and used his hand to push up, the tile came loose. 

Xu Feiyang put in his Bluetooth headset and put his phone in his pocket. With a leap and a pull of his hands, he easily leaped up into the vent on the roof.

After entering the vent, Xu Feiyang covered the hole again with its original tile.

"To the left. Climb faster! There are fewer people here.

"To the right, continue!"

Even though he was a vent, Xu Feiyang still knew the general direction to get out of the building. If he went to the right, he was walking into a dead end.
