The Man In Green

Two weeks had passed since Han Cai arrived at Ravenfall city, and every night the man who had opened window would come, bringing tea and food. But he would not sit with Han Cai. He would keep the tea and food on the doorstep, knock three times, and then leave.

One day when the man brought the food and tea, He did not leave after knocking on the door.

Han Cai opened the door and saw the man standing with a tray in his hand. Han Cai nodded and went inside and sat on a chair. The man followed. He kept the tray on the table and sat down on the opposite chair. He made tea for Han Cai and himself and started sipping.

While sipping tea, he spoke. 

"The area where Liu Jie is being kept is located deep within a mansion, in the upper levels reserved for the Yang family. The mansion is heavily guarded by cultivators and equipped with advanced security measures to detect any intruders.
