On March 25th, at nine o'clock in the morning, the sun was covered with a veil, and from a distance, it was hazy and mysterious.

When Bai Lotian pushed open the glass revolving door and walked into the lobby on the first floor of the hotel, he saw Alyssa sitting on the sofa on the left side of the hall reading a magazine, she was wearing a duck blue casual dress and a blue-gray backpack resting next to her.

"Hey Alyssa, how was your rest yesterday?"

"I'm fine, thank you, Dr. White. Alyssa stood up, clutching her backpack in her hand, "Are you going to the Atmosphere Now?"

"Yes, let's go to Professor Wind's office first. ”

After only ten minutes' drive, the car turned into a tree-lined courtyard, facing a quaint three-story building with red tiles and white walls and high eaves corners.

Bai Lotian got down from the cab, opened the car door for Elisara, and along a path paved with blue bricks, the two walked into the first floor of the office building.

In the foyer on the first floor, near the right, there is a rectangular table, painted dark yellow, and a red-faced security guard in a black uniform sits on a chair in the back, his large-brimmed hat tilted to the side, the corners of his mouth drooping, drowsy.

In the middle of the table rests an open notebook filled with visitor information. Bai Lotian picked up the signature pen next to him and registered Alyssa's information on it, at this time, the security guard was startled, his eyes smashed a few times, and he woke up.

Walking up the brown-red wooden staircase, the two walked straight up to the third floor, where they came to the easternmost room on the third floor, where the words "Office of the Whisper of the Wind" were written.

A woman with explosive hair passed by them, with a look of surprise on her face and an inexplicable smile.

Bai Lotian took out the key, inserted it into the lock, turned around a few times, pushed the door open, walked to the window, and opened the curtains.

There was silence in the office, a deathly silence, which made people feel unusually dull.

Topographic maps and weather maps are pasted on the walls, cups on the coffee table are neatly arranged, and dark gray top hats are hung on hangers in the corners.

"Look, this is Professor Wind's office. Bai Lotian said infinitely sadly.

Alyssa didn't speak, silently walked to the desk, looked at it carefully, and felt the pen in the pen holder, as if to put it all in her brain.

Alyssa's expression was solemn, and her movements were very slow, as if she was afraid of waking someone else. She walked over to the weather map and stroked it with her fingers. She pulled open the bookcase against the east wall, which was lined with various books, all carefully collected by Professor Feng.

"Dr. Bai, my mom said, let me bring back some of my father's private books, is it okay?" asked Alyssa back.

"Since it's Professor Feng's personal belongings, you're his daughter, of course you can. ”

"Thanks, you can rest first, I may have to spend some time. Alyssa said, pointing to the couch.

"Okay, please. Bai Lotian said, walked to the sofa, and sat inside.

Alyssa stood in front of the bookcase, very attentive, carefully flipping through each book, even the thin notebook. She opened all the drawers, and looked at the contents again and again, as if she was afraid that she would miss something.

About an hour later, Alyssa picked up a few papers from her bookcase, put them in her backpack and walked behind her desk, opened the drawer and looked at it, which contained nothing but a few packets of coffee.

Bai Lotian followed Liu Qing's explanation and secretly wrote down the items that Alyssa turned over and took away.

"Dr. Bai, is that all my father's information?" said Alyssa, a hint of disappointment on her face.

"Seems like that's all. Well, he doesn't have another office. Bai Lotian replied.

"Dr. Bai, do you know that my dad received a letter from the United States a month ago with a technical research report. Alyssa said, with an unnatural expression on her face.

"I heard Professor Feng talk about it, it seems to be Professor Thomson's research results. He liked it and watched it many times. ”

"Do you know where the letter is?" Alyssa's eyes sparkled.

"I'm sorry, I don't know. ”

"Well, okay then. Alyssa couldn't hide the disappointment on her face.

"Is it important? I'll find it later, and I'll send it to you." ”

"It's not too important, forget it. Alyssa said, avoiding Bai Lotian's gaze and surveying the room.

Suddenly, as if she had discovered a new world, she walked behind her desk.

Moved away from a very tall green plant, there is a light gray safe behind it, and if you don't look closely, you can't find it at all.

"Dr. Bai, do you have the key, can you open it?"

"I don't have the key, I guess the police can open it, and I can help you get in touch. ”

Hearing the word "police", Alyssa's eyes flashed with a hint of horror, and she disappeared in the blink of an eye, and hurriedly said, "Then forget it." ”

Walking out of the office building, the sun was shining, shining on the golden zipper of Alyssa's backpack.

"Dr. Bai, is my father's house far from here?"

"Not too far, let's go. Bai Lotian said, walking towards the parked car, and Alyssa walked behind him, silent, as if full of thoughts.
