Xia Zhining gently placed a bunch of white jasmine and elegant daisies in front of Ji Yanqing's tombstone.

Ji Yanqing had a handsome face that was very similar to Ji Shuyun, with an unquestionable righteousness between his brows.

Even in a frozen photo, his calm and resolute temperament is still clearly visible.

She stared at the photo of her biological parents in silence for a long time, and finally asked softly, "Brother, how did Dad sacrifice himself?"

Ji Shuyun stared into the distance calmly, his voice muffled as he said, "Dad was a criminal police officer when he was alive. He handled many major cases."

"Later, due to the sequelae of serious injuries, he was transferred off the front line."

"But he didn't die in the line of duty."

Ji Shuyun paused. "According to the official report, he was on his way home from get off work. While trying to save a little boy who ran into traffic, he was hit by a dump truck that couldn't brake in time... and died on the spot."

“…was the child saved?”

Xia Zhining asked softly.

"He was saved and only suffered minor injuries. But Dad didn't wake up."

Ji Shuyun paused, as if suppressing his emotions, "Because he was not on duty when the incident occurred, so... he was ultimately not recognized as a martyr."

Xia Zhining's heart also sank, as if something was gently gripping it, with a sour and painful feeling.

Ji Shuyun raised his hand, and gently rubbed the top of her head with his warm palm. His voice was low and gentle: "Dad has always felt guilty."

He paused, as if he needed some strength to continue with that heavy memory: "When Mom gave birth to you, Dad was on a critical mission in another city and couldn't get away."

"It just so happened that I was seriously ill at that time, and the house was in complete chaos... You and Xia Qingqing were accidentally taken away by mistake in that chaos."

"This mistake lasted for more than ten years."

Ji Shuyun's voice was filled with a heavy feeling that was hard to let go. "Now I know that your Xia family has suffered so much injustice. I'm sorry, Ningning..."

Xia Zhining immediately shook her head vigorously, her eyes slightly red but she tried to smile: "Brother, don't say that. You were still a child back then, only four years older than me."

She leaned closer and said, "Besides, look, aren't we together now?"

"Captain Yang also said that everyone in the police station now recognizes us as the 'twin stars of the police force'!"

Ji Shuyun looked into his sister's bright eyes, and the softness in his heart was touched. Finally, he raised the corners of his mouth slightly and nodded solemnly: "Yes!"

After visiting her relatives, Xia Zhining felt a faint melancholy in her heart.

Seeing her depressed, Ji Shuyun gently suggested, "Mom left some manuscripts in a bank safe. Let's go take a look. Maybe it's time to give them to you."

They went to the bank together.

In the solemn safe, the elder brother took out a well-preserved wooden box, in which were neatly placed the manuscripts left by his mother Xia Tang.

Xia Zhining put on white gloves and carefully took the slightly yellowed pages.

After turning a few pages, her breathing became slightly stagnant.

The manuscript contains some hand-drawn pictures, including animal skeletons and cell diagrams.

The characters in the manuscript are arranged in a strange way, interspersed with many unfamiliar symbols.

Xia Zhining quickly recognized that this was a rare script called Limbu, which originated from a small ethnic group in the foothills of the Himalayas.

A few years ago, when she was working with an international animal rescue organization on the Nepal border, she had occasionally seen this kind of writing in local ancient religious ceremonies.

What shocked Xia Zhining even more was that this was not the first time she had seen the shape and brushstrokes of this manuscript.

When she was in the wealthy Xia family, her adoptive father Xia Cheng once took out a few fragments of pages with a similar style and asked her to try to translate them.
