When Chu Longfei kicked the wall, he realized he had reached the side of the window. Fumbling, he reached out his hand, going through a fierce internal struggle. He was afraid to touch that sticky substance again, and also feared feeling the poisonous snake that could bite.
As soon as he touched something icy, he quickly withdrew his hand. It took a while for his brain to react before he reached out again because he was certain he had touched glass. So, he traced his hand down the glass until he finally found the window latch. Gently twisting it and lifting, the latch opened.
Excited, he pushed hard against the glass.
