Am I a Kamen Rider or the real young master who was switched at birth?

Ye Yang stood in the corridor outside the Academic Affairs Office, looking at the man leaning against the wall leisurely flipping through sticky notes, and several questions popped into his mind at the same time.

He looked Hai Dong up and down, then asked, "Hai Dong, what brings you here?"

Hai Dong folded the note and stuffed it into his pocket, then leaned against the wall, tilted his head, looked at Ye Yang, and said in an extremely casual tone, "If I said I was just passing by—would you believe me?"

Lin Yumin took half a step forward, her center of gravity slightly lowered, and her right hand naturally hung at her side.

She was familiar with this person; he had disguised himself as a waiter and sneaked into the VIP room at the Star-Picking Pavilion last time. She wouldn't let her guard down just because Ye Yang said he was "half a friend."

"Mr. Haidong, you always seem to just happen to pass by us. Last time it was the Star-Picking Pavilion, and this time it's the Federal Military Academy."

Lin Xingran took a step forward, hands on her hips, and replied in a tone that said, "Yeah, are you eyeing something at our school?"

Lin Ying nodded next to her second sister. She didn't speak, but her eyes showed an obvious wariness.

Hai Dong lowered his arms from his chest, his expression still nonchalant.

He reached into the card box at his waist and pulled out the fake King of Silent Beasts crystal core. The crystal core was now only half left, and the energy halo inside had been completely extinguished. Only a few faint dark purple lines were still weakly pulsating deep within the wreckage.

"Hey—I can't keep this a secret for you anymore. This is bad."

Ye Yang took the half-finished crystal core and looked down at it. There were several cracks on the edge of the broken surface, and extremely fine fragments would fall off if you touched it lightly with your finger.

He looked up at Hai Dong, asking with some curiosity, "How did it break? Although this crystal core is just a shell, it's quite hard. Ordinary energy impacts would at most create a few cracks. The cracks on this cross-section are too deep and too dense, as if it was repeatedly bombarded by some high-frequency energy to shatter like this. Did you run into someone from the organization?"

"Yes, a few days ago we were chased for several blocks by a group of very strong guys," Hai Dong said casually.

He took the remaining half of the crystal core from Ye Yang's hand and casually stuffed it back into his pocket. Then, with his hands in his pockets, he leaned against the wall, tilted his head slightly, and the smile in his eyes faded a little.

Ye Yang frowned. He recalled the last time he fought alongside Hai Dong in the woods, witnessing him summon several knights at once using the Diend Driver, and how the mercenaries from those organizations were almost powerless against him.

There are very few people in the Federation who can outrun Hai Dong Da Shu.

"Very strong? Even you couldn't handle them? Last time you single-handedly wiped out the entire pursuit team in the woods, so theoretically, very few people should be your match. When did Zero acquire such a group of powerful experts?"

"So I'm still standing here, aren't I? But during the fight with them, this crystal core was shattered. After they get those fragments, they'll definitely find that this crystal core is just a hollow shell, not the real King of Silent Beasts crystal core. Judging by the timeline, they should already know that the crystal core from the Star-Picking Pavilion is fake."

"Thank you so much this time. You used the fake crystal core to distract so many of them, giving us enough time to investigate the spies at the auction. If you hadn't drawn the organization's people away, they might have already made their move at the Star-Picking Pavilion on the day of the auction," Ye Yang said solemnly.

Hai Dong waved his hand casually, as if being thanked meant nothing to him.

"Oh, right—I overheard a conversation between some of their leaders while I was on the run. Besides saying that the crystal core was fake, they kept mentioning an incredible treasure. It seems to be inside this school, so I came here."

Hai Dong spoke in a casual tone, his gaze sweeping over Ye Yang's shoulder to the outlines of the teaching buildings and training grounds outside the window, the playful smile on his lips deepening even further than before.

Ye Yang frowned slightly: "A treasure? Inside this school?"

He subconsciously turned his head to look at the three Lin sisters, his gaze first landing on Lin Yumin's face.

Lin Yumin was the person he knew who was most familiar with the school. She had served as the student council president for several years, attended countless internal school meetings, and could even recite the design flaws of the training hall's fire protection system.

Lin Yumin met his gaze and slowly shook her head, her brows furrowing slightly: "No. I've been in the student council for so many years, and I've never heard of any treasures in the school. I review the school's asset inventory every year, and all valuable items that need to be registered are on the list."

Lin Xingran suddenly raised one hand high and said in a somewhat urgent voice, "I've heard a legend! Do you guys remember it? Our school has a lot of campus legends, like the will-o'-the-wisps on the back mountain, the bookshelves in the library basement that move by themselves, and the sound of someone knocking on the wall in the training hall at midnight."

"Those are all from those ten rumors! There are ten rumors in total, and they are brought up and discussed again on the school forum every year when new students enroll."

"Legend has it that before our school was built, this place was the core of an ancient sealing array, sealing away a gigantic monster called the 'Abyss Beast,' which was dozens of times larger than the largest known silent beast!"

"It sleeps at an unknown depth underground, waking up once every few hundred years. Each time it wakes up, it triggers a super-large-scale Silent Beast tide, which has almost wiped out the entire Federation several times in history! When the first principal built the school, he deliberately covered the school with the seal, using the entire school as the vessel of the seal to suppress it underground."

After hearing these words, Ye Yang remained silent for several seconds, then asked with great curiosity:

"Where did you hear this? These things sound so real, including the principal's bloodline, Yuanxin, and the Zhenyuan Ancient Sword—these details are too specific, it doesn't seem like something a student would make up."

"Oh, this is one of the top ten rumors in our school! Let me tell you, although these rumors sound outrageous, each one has a corresponding explanation, and some have actually been verified by people."

"And then there's that will-o'-the-wisp on the back mountain—it's said that a student was practicing his kung fu on the back mountain one night when he saw a woman in a long white dress floating in the woods. When he chased after her, he discovered that it wasn't a woman at all, but a silent beast that had taken human form."

Seeing Ye Yang's expression, Lin Xingran quickly explained that she was seriously providing this as a clue, not joking.

Hai Dong leaned against the wall and listened to Lin Xingran's story from beginning to end.

"Interesting. An ancient seal. Sounds like a really good thing. I need to check if this rumor is true or not. Maybe there are a lot of treasures inside. The fake crystal core I had last time could only be used as a nightlight. I hope this Abyss Core won't disappoint me."

As he spoke, he straightened up from the wall, put his hands in his pockets, and started walking towards the stairwell.

Ye Yang reached out and grabbed Hai Dong by the back of his collar, pulling him back a small step.

"Wait, wait—don't rush off. It seems like Tsukasa Kadoya has come to this world. I just checked his file at the registrar's office, and he registered as a Super A-level teacher under the name 'Wang Xiaoming,' with his office on the third floor of the administration building. He's in this school right now."

Hai Dong was grabbed by the back of his collar, and leaned back slightly. Then he steadied himself and turned to look at Ye Yang.

"Oh—he's here too? This makes things even more interesting, doesn't it? With Shi here, that Zero organization is in even worse shape. I've worked with him several times, although every time he ends up nagging me, 'Can you please stop stealing things that will destroy the world?'"

He reached out and patted the hand Ye Yang was using to grab his collar, saying with a hint of teasing in his voice:

"Perhaps we'll meet again on our treasure hunt. Alright, I've given you all the information. You can verify the Abyss Beast information with the principal, and I've also told you about the new developments of the Zero Organization—now I need to go find the real treasure."

Hai Dong gently removed Ye Yang's hand from his collar and turned to walk towards the stairwell.

"Wait, wait, let's go together this time. Aren't you looking for treasure? We'll have a better chance of success if we go together. Besides, Zero's group is also active. If their target is the Abyss Beast, then you going in alone would just be scouting for them."

"This seal sounds terrifying. If you accidentally break it, the Federation may face a new wave of Silent Beasts."

After saying this, Ye Yang paused for a moment and added, "Besides, Shi is also at school. If he knew that you went to break the seal alone, he would probably say that 'your ability to cause trouble hasn't diminished at all over the years.'"

Hai Dong stopped and turned to look at Ye Yang. His expression stiffened slightly when he heard Ye Yang's last sentence, then he twitched his lips and muttered in a low voice, as if he had been hit where it hurt but refused to admit it:

"I'm not that unreliable—well, what you said makes sense. The group that chased me last time was indeed not easy to deal with, and the seal on the Abyss Beast does sound much more complicated than the one in the museum."

He pulled his hand out of his pocket and stood still, as if he were seriously considering the matter.

Just as Hai Dong was still hesitating, Lin Yu Mian reached into her pocket and pulled out a diamond.

The diamond was about the size of a thumbnail. Under the direct sunlight of the afternoon sun, it refracted an extremely dazzling light, and from different angles, one could see alternating halos of dark blue, pale purple, and very pale gold.

She held it up to her eyes, letting it slowly rotate, then handed it to Haidong, saying calmly, "Mr. Haidong, this is my payment—is that alright?"

The moment Lin Xingran saw the diamond, she felt as if she had been electrocuted. She covered her face with her hands and gasped in surprise.

"Sister! That's the Star of Africa! It's something Grandpa brought back from Africa for you! And you actually gave it to Haidong as payment!!"

Hai Dong took the African Star and held it up to his eyes to examine it carefully.

He turned the diamond several times, facing the light from the window, and squinted to look at each facet of the diamond as the light refracted inside.

He took the diamond from his eyes, a satisfied smile spreading across his face. He carefully placed it into a hidden compartment in his card holder, then looked up at Ye Yang and Lin Yumin, giving them an extremely amiable smile: "You have a good eye for people. Alright, since you're a big fan of Shi, I'll help you one more time."
