If the Great Tang Emperor had known who had built the Zhen Yun Ding, that would have truly been a surprise.
Cheng Guang had simply asked in passing, and it didn't matter that the Great Tang Emperor hadn't been able to answer.
Cheng Guang then asked again, "Did you ever have contact with this Zhen Yun Ding in those years?"
When Cheng Guang asked this question, his gaze was tightly fixed on the Great Tang Emperor.
Such a demeanor indicated that this question was very important to him.
The Great Tang Emperor, feeling the intensity of Cheng Guang's gaze, inexplicably felt a great deal of pressure. After swallowing dryly, he said with a somewhat hoarse voice, "Actually..."
"At the beginning of the Great Tang, we did have this Zhen Yun Ding."
"At the founding of the Great Tang, someone presented nine Zhen Yun Ding as a tribute."
"Then, my father, the previous emperor, used these Zhen Yun Ding to suppress the nation's fortune."
