The next morning, students from various Hogwarts houses sat around a long table in the dining room.

The air was filled with the tempting smell of bread, pastries and grilled sausages.

Ron had his usual appetite, but Harry next to him had a tense face and seemed a little unhappy.

"What's wrong, Harry?" Ron asked with a smile while holding his knife and fork. "Smile. Isn't it worth a few days of happiness to win against Slytherin and that bastard Malfoy?"

"I'm not unhappy, I'm just not awake yet..."

Harry forced a smile, then grabbed his knife and fork and began to eat his breakfast.

Hermione saw that he was worried, frowned, and asked in a low voice: "What happened last night?"

"……nothing."

Harry shook his head and didn't tell his two friends what happened last night.

Last night, before he returned to the dormitory, the house-elf Dobby appeared again. He warned Harry again and wanted him to leave the school. In his nervous words, he accidentally revealed the fact that he controlled the Bludger to attack him.

This made Harry feel sad, and he couldn't help but feel worried.

From Dobby's words, he could tell that the legendary chamber of secrets had really been opened, and that there were very dangerous things inside...

Hermione frowned and opened her mouth to ask more questions.

But at this moment, a tall and thin Slytherin senior passed by Harry, causing her to subconsciously shut her mouth.

Ender glanced at Harry, who was preoccupied with his thoughts, and then continued forward, ignoring the strange looks from the Ravenclaw students around him, and stood behind the quiet blonde girl not far away.

"Fana, come out with me for a moment, I have something to talk to you about."

The cold voice caused the surrounding Ravenclaw students to gasp.

Fana frowned slightly and looked at Ander's face carefully. Seeing that he was still as calm as ever, she knew that he really had something very important to talk to her about.

Without hesitation, Fana picked up a piece of bread, took her schoolbag and followed him out of the restaurant.

Seeing this scene, the young girls were whispering to each other, and seemed to have started to imagine things because of the two people's actions.

Arriving at a quiet corner of Hogwarts Castle, Fana nibbled on some bread and asked softly, "What's going on?"

Ender waved his wand to block out the surrounding noises, then looked at her seriously and said, "Two things. First, the old wizard from the East has reached an agreement with Headmaster Dumbledore. They will launch the 'East-West Exchange Student' activity. There will be only two students in the first batch of exchange students. One of them is me, and the other candidate is me. I recommended you to Headmaster Dumbledore."

“…”

Fana frowned and asked in confusion: "What are the benefits of participating in this event?"

Ander said softly, "Of course there are benefits. The Eastern wizarding world has a longer history than the Western wizarding world, and the accumulated experience and knowledge must be quite rich. Even if you don't study in depth, it is an excellent opportunity to broaden your horizons and enhance your strength."

Fana nodded thoughtfully and said, "Okay, I'll join. What's the second thing?"

Ender's face turned serious. He took out a black-covered book from his arms and placed it flat on the windowsill.

Fana was slightly startled, then she couldn't help but widen her eyes and whispered, "This is...Tom Riddle's diary?"

Ender nodded slightly, looked at the black cover of the diary and whispered, "Someone threw this diary into my bedroom last night. I guess it was probably Ginny who was controlled by Tom Riddle..."

As time travelers who are familiar with the plot, they naturally know what the recent locked room incident is all about.

The cause of the incident was the diary of Tom Riddle, or Voldemort.

In 1943, Tom Riddle, who was in the sixth year at Hogwarts, made this diary into a Horcrux and stored his memories at the age of sixteen in it. After becoming Voldemort, he gave the diary to Lucius Malfoy, who was a Death Eater at the time. Lucius kept the diary secretly.

Until this summer, in order to discredit Arthur Weasley, expel Dumbledore from Hogwarts, and get rid of a very troublesome dark magic item, Lucius secretly gave it to Ginny Weasley in Flourish and Blotts.

At school, Ginny quickly learned how to communicate with Tom Riddle through her diary, but she didn't know that the person in the diary was the sixteen-year-old Voldemort. She just regarded him as an understanding and confidant, and confided and shared all her inner thoughts with him.

As time went by, young Ginny was gradually controlled by the diary because of her weak will.

Tom Riddle gradually became powerful and finally controlled Ginny, forcing her to open the Chamber of Secrets, release the Basilisk, and write warning words on the walls of the castle corridor.

According to the normal plot development, Ginny will gradually realize the fact that she is being manipulated, and throw the diary into the toilet and flush it away. Then it is flushed out by the water in the toilet, falls under the sink, and is picked up by Harry Potter.

But before all this happened, Tom Riddle's diary came into Ender's hands...

Fana frowned and analyzed: "Ginny is kind by nature. It is impossible for her to throw the diary to you after discovering that there is something wrong with it. So the person who threw it to you can only be Tom Riddle who possessed Ginny, but why would he do this?"

"Could it be that he discovered your secret?"

Ander was stunned by Fana's subconscious guess. He couldn't help but ask cautiously: "What secret?"

"..." Fana knew she had said something wrong, so she pursed her lips and shook her head, "Nothing."

Ander's face was uncertain. After thinking for a while, he sighed and said, "Did you find out?"

Fana stared into his eyes, and seeing that there was no murderous intent in his eyes, she nodded gently: "Remember the afternoon of the third week of school? I was in the classroom at the time and saw you slap a mosquito to death in the corridor, and then controlled the mosquito to fly. That kind of flying was not floating, nor was it resurrection from the dead, but flying while maintaining the state of a corpse."

"So, I guess your magic attribute should be dark, and you may have the ability to control corpses."

“…”

The muscles on Ander's cheeks twitched slightly, and he couldn't help but complain in his heart.

Can you see this too?

You still remember this?

Seeing Ander in shock, Fana smiled faintly.

She stretched out a white and tender finger, touched her temple and whispered, "I said, my brain works well and my memory is excellent. If you need, I can also tell you how many times you waved your hands when you passed that corridor, or how many steps you took in total..."

Similar to Ander Ker, Fana's powerful time-traveling soul also resonated with magic power and gained abilities similar to the Memory Palace, which allows her to retrieve past memories at any time and review knowledge and conduct theoretical research in her sleep.

Ander couldn't help but say, "You really are a monster!"

Fana smiled faintly: "Thank you for the compliment!"

Ender sighed and whispered, "Well, since we are now partners, I can tell you that my magic is indeed inclined towards the dark arts. This may be the reason why Tom Riddle came to me."

"So now the question is, what should I do with this notebook?"

Fana thought for a moment and said softly, "Throw it away, or return it to Ginny or other innocent people. You can't do such a thing, and it doesn't make much sense. Tom Riddle has already set his sights on you. No matter who you give it to, it may eventually come back to you. But if we destroy it, we don't have the ability to do so for the time being..."

Ander shook his head and said, "I've already considered what you said. I want to hear other suggestions."

Fana nodded and said softly: "I have two suggestions. Either give it to Harry Potter and get the plot back on track, or give it to someone who has the ability to destroy it, such as Headmaster Dumbledore, or a powerful wizard of the same level as him..."

Ender thought about it seriously for a while, and finally shook his head and said, "Neither is good. If we hand it over to Harry, it may not necessarily get the plot back on track. If we hand it over to Headmaster Dumbledore, we won't be able to profit from this matter."

Fana frowned and asked, "I've always wondered what kind of benefit do you want to gain from this?"

"What do you think?" Ander asked calmly, "Since you know the secret I'm hiding, you should understand how precious the basilisk's body is to me, right?"

Besides, the tusks, skin and venom of the basilisk were extremely rare materials, and Ender had been coveting them for a long time.

"I've already asked Headmaster Dumbledore." Ender said softly, "The exchange student program will begin in seven days. We don't have time to wait for Harry and the others to take action. We must enter the Chamber of Secrets as soon as possible..."

Fana frowned and asked, "Are you sure you can handle the basilisk?"

Ander nodded and said, "If we use all our strength, then we can succeed, and we have a good chance of success."

Fana shook her head and said, "But if you plan to go all out, you can't bring Harry and the others with you. Without Harry, there will be no Parseltongue, and without Parseltongue, you can't open the door to the Chamber of Secrets - unless you use his help."

Having said the last sentence, Fana cast her eyes towards the diary and then sighed softly.

"So, you've already made up your mind, right?"

Then why are you asking me?

Fana added silently in her heart, but she didn't say it out loud.

Ender fell silent, apparently accepting this fact.

Fana looked at the diary and asked softly, "Have you ever tried to communicate with Tom Riddle in the diary?"

"not yet……"

Ander shook his head and said, "I want to discuss it with you first, and then decide whether to communicate with him."

Fana was slightly startled when she heard this, then the corners of her mouth curled up, revealing two shallow dimples on her fair face.
