The Chinese girl from Hufflepuff is both timid and brave

Sun Zhu didn't think much, he quickly went forward and pulled Lucy up, then looked at Fina and said, "Why did you run out? Where's Karina?"

"She heard Angelina say there were Dementors, so she went out to help. I was worried, so I followed her out to take a look, and then I saw..." Fina was obviously also very cold, "a few scary black shadows ran away, and she fell to the ground, saying there were two students ahead."

"Have they gone to look for them?" Sun Zhu quickly cast a heat wind spell on them and looked around. "The Dementors have actually come to the car? How many of them are there... No, we have to go there quickly. My Patronus is left with Luna, but she is alone."

Lucy's trembling hands suddenly clenched Sun Zhu's sleeves again. Her lips trembled and tears fell in large drops. It was obvious that she was not standing steadily: "Senior sister, it's so cold, they are coming again..."

Sun Zhu clenched his wand tightly, considering whether to call back his little oriole immediately, but he was also worried about Luna's situation. Fina bit her lip, glanced at Lucy, whose face was full of tears, and waved her wand again, repeating the spell.

Sun Zhu saw cold sweat on her forehead and quickly put his hand on her shoulder: "Relax, others will be here soon, nothing will happen."

Fina summoned a string of silvery dots of light, which still did not gather into any specific shape. But she closed her eyes and continued to repeat.

Sun Zhu kept refilling the three of them with hot wind spells to keep them warm, and beads of sweat appeared on his forehead. At this time, they were in the sightseeing corridor, and the windows on both sides were open for some reason. The warm wind that gathered was blown away in the blink of an eye, but she couldn't free her hands to close the window.

"I...saw...that shadow again..." Fina's struggling voice came. Sun Zhu hugged Lucy into his arms and pulled her sleeve.

"Don't look at them!"

An overwhelming sadness filled her heart. Sun Zhu felt that she was completely out of breath. Her whole body was freezing cold, her blood flow slowed down, and her heartbeat became slow and heavy, beating laboriously in her chest.

Lucy in his arms was already unconscious.

No, she had to call the bird, otherwise, Lucy, who had already been hurt by the Dementors, would be in even worse shape.

"Zhu..." Fina turned her head and saw the two people half-kneeling on the ground. She also staggered. She waved her wand again, making the silver-white light spots move closer to them.

Even if it's not formed and can't be used to drive away Dementors, it's better than nothing.

Sun Zhu heard the call and was about to call his bird, but he felt the suffocating pressure in his heart suddenly eased.

She looked up and saw that there were many small silver flies on the ends of her hair. She was so surprised that she was speechless.

"What's this……"

"Are you guys okay?"

"Fina, you, look..."

Fina leaned over and squatted beside them, looked at Sun Zhu, then looked at the spots of light lingering around them, and temporarily lost the ability to speak.

"Yes, fireflies... Fina, your patronus is actually a firefly?" Sun Zhu finally reacted, rubbed his frozen hands, and blew a hot wind spell on them, "It's a large group of fireflies. I've never heard that a patronus can be a group."

“I didn’t either…” She stared blankly at the flying insects, rubbed her eyes, and exhaled, “Whatever it is, I finally summoned it, them.”

Sun Zhu nodded and helped Lucy to stand up: "Let's meet up in the front box first, can you still walk?"

Fina took Lucy's other shoulder and said, "Of course, other people must have encountered Dementors as well. We have to go check it out."

The door of the compartment at the end of the first carriage was open, and a large patch of silver light illuminated the entire aisle. Lupin was guarding the door. When he saw them coming, he was startled and the silver wolf jumped over.

"Take, Delphine, how come...did you encounter Dementors?"

"Yes, but they have been chased away. Professor, there are students who need treatment. Also, what's the situation at the front? Why are you guarding here?"

"More than twenty Dementors appeared in groups, attacking the driver's cab, the conductor's room and the prefect's compartment. I am here to stop the other Dementors that come. There are seven or eight students who know the Patronus Charm in front of us to resist them together. You..."

"Hurry and let her in!" Hermione appeared from behind Lupin, stretched out her hands and pulled Lucy over, "We have hot water and blankets here, don't worry! Miss Lovegood, come and see, is this your roommate?"

Luna also poked her head out from behind the door, glanced at Lucy, and nodded: "She must have been scared by those prison guards."

"That's called Dementors. I've heard my godfather mention them. They're very scary. I don't know how they got here." Harry also squeezed over, secretly glanced at Sun Zhu, and then retracted his head.

But he was pushed by Ron who was following behind him and almost hit Lupin.

"I know, I know about this. My dad once mentioned it to mom when he was drunk. This is because Azkaban was blown up by the You-Know-Who's former subordinates, and most of the prisoners inside escaped. These Dementors came out to chase them!"

"Ron, please move aside. I need to pour her some hot water." Hermione snorted. "Also, the Dementors can't be here just to chase the prisoners. This is a special train for Hogwarts. How could there be prisoners here?"

"You never know!" Ron muttered, reluctantly moving away. "I have to go find my sister and Fred and the others."

"Don't go anywhere! The Dementors haven't left yet." Sun Zhu regained some strength and pressed Fina down on her seat. "You just summoned your Patronus, it's not stable, just in case you should stay here. I'll go to the front to see if anyone can help."

"Zhu!" someone called from behind.

She turned her head in surprise and saw Harry with a red face, whispering, "Senior Diggory should have gone to the front with Percy, the Prefect's Box No. 1."

"Okay, I understand." Sun Zhu smiled and looked at Lupin again, "I'll leave them to you to take care of them first. I have to go check on the situation."

Lupin frowned, "No, you should stay here too. There are two supporting Aurors ahead, dealing with those monsters, their safety is guaranteed. I have sent a letter to the Ministry of Magic, and more people will be here soon, you just need to wait here."

"Please believe that I won't hold you back." Sun Zhu shook his head. "There are so many Dementors, and most of them are just students. There are less than ten of them. How can I be at ease?"

She ran forward resolutely, while the younger students who stayed behind whispered to each other.

"Strange, isn't she just a student?" Ron scratched his head, "What's the difference between her and the people before?"

"I'm afraid you won't understand until you become a prefect when you are capable enough..." Hermione rolled her eyes, "the principle that those who are capable should do more work."
