Chapter 258: Is the young master alright?

When Gu Ling returned to the capital city and stayed in the Marquis Chang Xin Mansion for the second night, the person who had been ordered to keep an eye on him finally noticed something.

It wasn't that Gu Ling did something, but someone came to find him.

"Gu Ling!"

From the voice, the visitor was a young man who stood outside and called for Gu Ling without approaching the door of his room.

The watcher immediately held his breath, focused, and listened carefully.

It was late at night, and Gu Ling had not yet rested. There was still a light in his room, and he was repairing the medical book that had been torn in half at Su Family Village.
