It was a polished wooden box, as big as a shoe box, with exquisite hinges. The wood was dark purple, with a dull light and a texture with thick lines. It was red sandalwood, and a flower was inlaid on the lid.

Beautiful cloud pattern.

Section Chief Liu opened the drawer, took out two pairs of gloves, and handed them to Bai Letian and Liu Qing. After putting on the gloves, they stood by the operating table and looked at Section Chief Liu.

Chief Liu opened the things wrapped in silk cloth layer by layer. As the silk cloth became thinner, Bai Letian's mood was like the waves in the sea, and the waves were tighter and the waves were so excited that he couldn't help himself.

When the last layer is opened, two items appear before your eyes.

Bai Letian took a deep breath, walked over, poked his head out like a duck, and looked closer and closer.

A yellowed parchment with a painting drawn with a brush on it. Due to the long time, the picture is blurred.

Another one is a yellowed five-pointed star with a diameter of about ten centimeters. It should have a good texture. The center is hollowed out and an irregular oval. The periphery of the five-pointed star is ground into a smooth pebbles.

Section Chief Liu said that this is the relics of Professor Feng Zhiyu.

"This five-pointed star should not be special," said Section Chief Liu. "As for this picture, I have carefully looked at it, it seems to have something to do with the weather."

"Is it an ancient map?" Liu Qing scratched his head.

"There is this possibility. Because the times are long, it is impossible to see that this is the marked area." Section Chief Liu replied.

"Can it be a landscape painting?" Bai Letian stared at the parchment and said to himself.

"That's also an extraordinary landscape painting!" Liu Qing said, "Otherwise, how could he be regarded as a treasure by Professor Feng?"

"It should be unusual, right?" Section Chief Liu asked back.

"What does sheepskin painting mean?" Bai Letian asked.

Section Chief Liu and Liu Qing both shook their heads, saying that they were incomprehensible.

"Maybe we don't know it now, but it will never be an ordinary item." Bai Letian continued.

"If you can figure out these things, you might be able to provide clues to solving the case." Liu Qing said regretfully.

"Is it related to meteorology? Why? Professor Feng is a well-known meteorologist." Chief Liu rubbed his hands and said, "So, Dr. Bai needs to use his professional skills."

"Maybe it will disappoint you, haha." Bai Letian said, "I have a request, don't know if it's appropriate?"

"What?" Section Chief Liu asked.

"Can you bring the stuff home?"

"In special circumstances, it's OK. You can go through the procedures later--------------------------------------------------------------------------------------------------------------

"You can complete the procedures and wait for the leaders to approve them and I will send them to you home, okay?" Liu Qing said.
