"Ahh My research, gone, gone, gone......"

When the black fog dissipated, I saw a little man covered in black in the corner, and when he saw that his research results had turned into powder like this, he suddenly grabbed his hair, his eyes were full of 'tragedy', and he sat on the ground and wailed.

Bai Xu looked at this sudden change, and he couldn't react a little.

Feng Xi was also made a little funny by this dramatic scene.

However, just then, a hoarse and low voice came from outside the dormitory door; "Chen Xue'er!"

The little girl who was still scratching her head on the ground and wailing, her body suddenly stiffened when she heard the sound.

After a while, I saw her turn her head and look at the white-haired old man who appeared at the door with a smirk.

"Teacher, I, I know it's wrong, in the future, I will definitely not do research in the dormitory, don't fine me again, I can't open the pot, this time I really swear." The little girl named Chen Xue'er suddenly raised her palm, and opened her mouth with a very pious and serious oath on her black face.

The white-haired old man was the old man who had just been at the door downstairs.

Feng Xi frowned slightly when he saw the old man appear.

Because, she didn't even feel when he appeared at the door.

The old man's face was very calm and serene, as if he had no emotion, and he saw that under his robe, the wrinkled right hand was gently raised.

A gold coin suddenly flew out of Chen Xue'er's body, and in the blink of an eye, the gold coin was placed on the old man's wrinkled right hand.

"It's exactly the hundredth time you've been fined, and if there's a second time, the amount of the fine will be doubled." A hoarse and deep voice came very calmly.

"Old ...... Teacher, you can't ...... me like this" When Chen Xue'er heard this, she cried and wailed.

But after the old man finished speaking, he didn't glance at the bird, and when he saw that the old man just glanced at the wind, he turned around and left slowly.

The dark eyes of the wind flashed slightly, looking at the back of the old man who had left, there was always a strange feeling in his heart, but he couldn't understand it for a while.

"Fengxi, do you also think that old man is very strange?" On the side, Bai Fu lowered his voice and asked in a low voice beside Feng Xi.

Feng Xi retracted his gaze at this time, looked at Bai Fu, and then nodded.

The old man was not only strange, but also very strange.

If he really saw through her identity, he shouldn't have let her stay in the academy.

But if he didn't see through her, then why did he give undisguised 'warnings' in front of her again and again.

He had just taken out the gold coin from Chen Xue'er, and glanced at her, it was obvious that it was another warning to her.

"What's so strange about this, that old man likes to pretend to be mysterious, in fact, it's just an old man who is greedy and loves money."

Not long after Bai Xu finished speaking, Chen Xue'er, who was sitting on the ground and 'wailing', had already gotten up, took a towel and wiped her black face and said very casually.

"Moreover, the old man loves to watch others cry and grabs the ground for him, and he has to be miserable, so he will feel comfortable, so I occasionally call him a perverted old man, you newcomers may not be used to it, just wait until you get used to it, by the way, my name is Chen Xueer, a first-grade class, and there is an experimental research class outside of class."
