Chapter 198: Mysterious Underground Mausoleum

"Brother, I know all about the young master's situation, do we know who did it?" Long Yun asked.

"It was Black Stone Gang's Hei Yao who did it," Dong Xiaotian said with a cold expression.

"Hei Yao? Our Dragon Tiger Corporation has no grudges with the Black Stone Gang, and we have long since withdrawn from the Tianhai underworld power struggles. What does he mean by this?" Long Yun expressed his confusion.

"He did it for this."

As Dong Xiaotian spoke, he opened a box in front of him. Inside lay a green disc, identical to the one displayed at the Mo Group exhibition.

Seeing the green stone disc, a flash of surprise crossed Long Yun's eyes. "He did it for the green stone disc?"

"That's right, I didn't expect that the Black Stone Gang would also be interested in this green stone disc," Dong Xiaotian said indifferently, his gaze fixed on the disc, reflecting a complex emotion.
