He pulled out another evidence bag, this one containing a crumpled shopping receipt.

The shopping receipt shows that the item Professor Li purchased was a pair of knee pads for dancing.

On the back of the shopping receipt, it was written crookedly:

"Yan, I'm sorry, don't blame grandpa."

The inspection officer explained: "This shopping receipt is wrapped around the pen."

"Professor Li must have been locked up alone when the tomb robbers weren't paying attention and stuffed the pen into the gap between the boards."

"Maybe he hopes that one day the police will discover that he was kidnapped on this ship, or maybe..."

The police officer from the medical examination department stopped talking here.

It was also Professor Li’s last words to his grandson Li Yan.

After seeing these two pieces of evidence, everyone present fell into silence.

Xia Zhining looked at Captain Yang and said solemnly, "Captain Yang, can Li Yan come out of the interrogation room now?"

"He has an important recording task tomorrow, bringing his grandfather's archaeological findings to the world."

"You must rest well tonight and stay in good condition."

Captain Yang nodded and said, "Let's sort out the tasks. We'll go back to the police station now. Three officers will stay behind to guard the scene."

The group returned to the Jiangcheng General Administration in a mighty procession.

In the Jiangcheng General Administration Bureau, the pale light in the interrogation room shone on Li Yan's haggard face.

He clenched his fists tightly, his knuckles turning white. "I tore that bracelet off in a fit of rage when my grandfather and I were arguing."

"My aunt bought the insurance for my grandfather. The reason for the change was that three months ago, my aunt said she didn't plan to return to China and wanted to settle in Country M. My grandfather changed the policy in a fit of anger."

Xia Zheng just looked at him indifferently: "Keep making it up."

"I know very well what kind of character people like you have."

"Your grandfather worked so hard to raise you, but you're such an ungrateful person that you don't know how to repay your debt and even try to anger him."

Li Yan suddenly looked up, tears glistening in his red eyes: "You don't understand at all!"

His voice cracked. "Tomorrow is the taping of the World Qi Dance Competition. Our choreography can bring Grandpa's archaeological discoveries to the world!"

"Bring it to the world?" Xia Zheng interrupted with a sneer, "Just you?"

He leaned forward, his shadow casting a shadow over Li Yan: "You're lying with your eyes open!"

"Little Ji, you're so crooked, there's no hope for you."

"I did get the question wrong!" Li Yan suddenly snapped, "But I didn't get the wrong person!"

“Everyone is good at different things!”

Li Yan trembled all over. "My grandfather's archaeological discovery, I re-interpreted it with street dance... This is what he was most proud of in his life..."

Xia Zheng shook his head: "You are not your grandfather's pride."

At this moment, the door of the interrogation room was opened with a bang!

Xia Zhining and Ji Shuyun stood at the door.

Xia Zheng narrowed his eyes and looked at the two of them: "Interrupting the interrogation is a serious violation of discipline! You—"

As soon as he finished speaking, Xia Zhining took a step forward.

"Expert Xia, the real culprit has been apprehended."

Xia Zhining threw the evidence collected at the scene in Xia Zheng's face: "Article 1018 of the Criminal Procedure Law states that if new evidence is discovered, the interrogation must be terminated immediately."

A sneer curled up the corners of her lips. "Or is it that Expert Xia can't even remember the basic laws?"

Ji Shuyun stepped forward and showed the documents signed by Captain Yang: "Ji Shuyun, head of the special task force, is now taking over this case in accordance with the law."

"Expert Xia, you're out of this case."
