Guan Feng nodded cryptically and reminded him, "Captain Chen, the testing must be thorough. The three suspects brutally murdered Chen Santai and are determined to put up a last-ditch effort. This is currently the only evidence we can secure."

Chen Xuewen pushed up his glasses and said seriously, "I will definitely test carefully and thoroughly, and not overlook any oversights."

Upon hearing this, Professor Zhang instinctively asked, "How long will that take?"

Chen Xuewen said, "It's hard to say! There are so many cultural relics, and each one needs to be tested. The key is that the brothers have been working all night. There are only two of us now, including me, so it will probably take some time."

Professor Zhang sighed and said, "These cultural relics are extremely precious, especially that ding (a type of ancient Chinese cooking vessel). Will you be able to test it without damaging it?"

Chen Xuewen said, "Please rest assured, we will not use any chemical reagents."

Professor Zhang said, "That's good."

Director Bai then asked, "Is this cauldron very precious?"

Professor Zhang said, "It's extremely precious! At the very least, it's an artifact from two thousand years ago, and it might even be one of the original Nine Tripods."

Director Bai was surprised.

He didn't know much about cultural relics, but he did know that Yu the Great cast nine tripods to suppress the nine provinces during his flood control efforts, and that these nine cultural relics were passed down through the Xia, Shang, and Zhou dynasties.

Director Bai said, "If it really is these nine cauldrons, then the history of our Hongcheng will have to be rewritten."

Professor Zhang said, "That's right! Even if there's only a slight possibility, it's enough to warrant attention. I've already reported it to the institute, and Secretary Chen has also reported it to the bureau. This matter will soon attract the attention of both the city and district levels. Speaking of which, I have to thank you for recovering this cauldron. Otherwise, if it had been lost, it would have been another lost cultural relic!"

Director Bai also sighed, "Yes, it took many years to bring back the twelve zodiac animal heads, and even then, several pieces are still missing."

They also realized that bringing these things back to the bureau was a lucky accident.

This case is more important than I imagined!
