Bai Lotian sat on a chair and drank a few sips of black tea, and about ten minutes later, there was a clicking sound in the corridor outside the door,

"Who's looking for me? Could it be that Xiaobai is here?" The person was still in the hallway, and the voice floated over.

Bai Lotian hurriedly stood up and walked in the direction of the glass door.

As soon as the door opened, a tall figure floated in, she was wearing a white dress embroidered with light purple azaleas, a pair of beige high heels on her feet, laces were the color of lavender, black hair floated behind her, her eyebrows were willow-shaped, she wore a pair of gold-rimmed glasses, her eyes were like two shining gems, her nose was high, her white cheeks were melon-seeded, and she spoke quickly, like beans sprinkled in a copper basin.

She is the famous meteorologist Hu Chengfang, a well-known expert on cold current snowfall in China, who proposed the multi-scale mechanism of Bohai Sea effect blizzard, and established a systematic conceptual model and forecast technical index system of cold current snowfall, inland blizzard and precipitation phase. In addition, she has in-depth research on the relationship between climate change and the evolution of the Earth's phases.

As soon as Director Hu entered the door, he looked at Bai Letian and walked straight over, "Oh, it's really Xiaobai, it was that gust of wind that blew the young leaders in the meteorological world, it's really brilliant!" Her exaggerated voice attracted everyone else to look over, and Bai Letian's cheeks suddenly turned red.

"Director Hu's praise made me drunk, haha. Bai Lotian laughed.

After shaking hands, the two sat down at the table.

"Director Hu, I would like to ask you an academic question. Bai Lotian said.

"Yes, I'm afraid I can't explain it comprehensively, but we can discuss it together. As soon as he talked about academic issues, Director Hu immediately came to his senses, and his eyes shone brightly.

Bai Lotian picked up the handbag on the table, took out the red wooden box inside, and laid it flat on the table.

When Director Hu saw the red wooden box, he didn't understand what he wanted to do, and he couldn't help but be stunned, with a puzzled look on his face.

"This is a relic of Professor Whisper of the Wind. ”

"Oh, I've heard about Professor Feng, I really didn't expect it, it's really a pity. Hu Taichang clasped his hands together, his face was solemn, and he looked at Bai Letian.

Bai Lotian opened the box, took out the things, and placed them in front of her. Then, he took out a pair of white gloves and handed them to Director Hu.

Chief Hu put on his gloves, grabbed the five-pointed star of Hetian jade, carefully placed it in front of his eyes, observed it for a few minutes, shook his head, and said that he couldn't understand it.

She put the five-pointed star back in its place, reached for the yellowed parchment, unfolded it on the table, and lowered her head, her eyes almost resting on the parchment.

"This doesn't seem to be compatible with the weather, huh?" Chief Hu looked at Bai Letian.

Bai Lotian handed the magnifying glass to Director Hu, "You are an authority, take a look." ”

Chief Hu took off his gold-wire glasses, held a magnifying glass in his hand, pursed his lips, and looked down at the contents of the parchment.

"As far as I can tell, the picture depicts an ancient Chinese glacier, probably at the southern foot of the Himalayas, on the border between China and Nepal," she said. ”

She sighed and continued, "It is valuable that it vividly depicts the gradual process of ancient glaciers, which is a dynamic evolution, not a static one. ”

Bai Lotian remained motionless and listened attentively.

"Combined with the leaf-like drawings next to it, if you analyze it at a deeper level, it is the dialectical relationship between climate change and glacier dissolution. ”

"Makes sense. Is it just a record of the meteorological observations of the ancients?" Bai Lotian said to himself, and he secretly wondered if this was Professor Feng's unintentional collection.

"It's possible. Hu Taichang replied, her fingers gently rubbing the "leaves" on the paper.

"Could it be that this is an ordinary five-pointed star?" Bai Lotian picked up the jade artifact and muttered to himself.

"Maybe. Chief Hu whispered.

"Could it have a special meaning?"

Hu Taichang crossed his hands on the table, did not answer Bai Letian's question, and fell into deep thought.

"Five-pointed star!" said Hu Taichang softly.

"Pentagram?"

"Yes, they're the same shape. Director Hu continued, "But what about .......", she stopped again, with a look of wanting to say something.

Bai Lotian looked at Director Hu, his eyes full of expectation.

After a pause for a few seconds, Director Hu continued:

"The pentagram was also known as the pentagram in ancient times, and in astrology, the five angles of the pentagram represent the five planets of gold, wood, water, fire, and earth, of which Venus represents the upper position, because the trajectory of Venus in the sky every four years is a regular pentagonal. There are eight ways to draw the pentagram, representing the use of the four elements of water, fire, wind, and earth to 'summon' and 'expel 'the earth'. ”

"It's so complicated, I didn't expect it. Bai Lotian exclaimed.

"Hmm. This is one of the earliest symbols in the world, and was used as a talisman to ward off demons and keep people safe, and began to be used before 4,000 BC. Some religions also believe that the pentagram has magical powers, can seal demons and prevent evil spirits, and they consider the pentagram to be a sacred object. ”

"Got it. Bai Lotian gave a thumbs up.

"The pentagram, which is considered sacred and magical in many cultures, conforms to the golden ratio of the line segments in the pentagram, which makes it the prime representation of the golden section. It is for this reason that the pentagram is always seen as a symbol of beauty and perfection. ”

"It's amazing. Bai Lotian said.

"Of course, what I'm saying is all speculation," said Hu Tai, "maybe it's just an ordinary five-pointed star, and who knows, maybe only Professor Feng can tell, but he has passed away." She sighed.

"But what does this central hollow ----- heart-shaped part represent?"

"I don't know. Perhaps, just to improve artistry. Director Hu said.

"There are still doubts, and they will always be figured out. Bai Lotian said softly.
