Capítulo 3787: Background of the Jin Clan

There was a wall in front of Ling Han, and there was nothing else.

He stretched out a hand, and began knocking on the brick.

Tong, tong, tong, the sound was muffled.

Ling Han switched to another brick, and knocked again. It was still the same, and he moved again.

After switching to a dozen over bricks, the sound suddenly changed, becoming very crisp and clear.

He revealed a smile. This was hollow.

"Tang Yan, Lady Jin," he called out.

Tang Yan walked over, a dazed expression on his face. However, Jin Yexue wore a smile of admiration as she said, "Sure enough, I wasn't able to fool you."

Ling Han merely smiled faintly.

"Yi, what kind of secret signal are you guys playing? Why don't I understand?" Tang Yan's expression was filled with confusion.

"If you don't understand, that's right." Ling Han pointed at that brick, "Come, smash it open."

Yet Jin Yexue shook her head, "Don't worry. There is no danger here."
