Chapter 638 Passing the Book_3

"Uncle Gu."

Gu Changhuai didn't respond.

After a while, Mo Hua sent another message, "Uncle Gu…"

Gu Changhuai still didn't respond.

"Is the Letter Token broken?"

"Didn't you receive it?"

Mo Hua muttered to himself and thought about it before continuing to send messages:

"Uncle Gu?"

"Uncle Gu?"

"Are you there?"

Perhaps unable to bear the annoyance any longer, the person on the other end finally replied:

"Not here."

Mo Hua: "If you're not here, who is replying to me?"

Gu Changhuai seemed to be quite irritated, and after a while, he calmed down and asked,

"What is it?"

Mo Hua: "That black residue, have you found anything?"

"Not yet, not so fast…"

"What about Flower Gentleman's Letter Token? Is there any information on it?"

"No…"

Gu Changhuai was halfway through sending his reply when he suddenly hesitated, "How did you know it was a Letter Token?"

Mo Hua: "I could tell at a glance!"
