Douluo Continent: The original Yu Xiaogang brutally defeats Tang San at the start.

Lin Yuan, the mastermind behind all of this, was currently in his dormitory, leisurely studying the perfectly replicated blueprints in the system space.

"I see. That's how the mechanism of the Zhuge Crossbow is designed. It's ingenious, with each link interlocking with the next."

With the system's assistance, these blueprints, which Tang San found obscure and complex and required a great deal of mental effort to study, became incredibly clear and simple in Lin Yuan's eyes.

Countless 3D exploded views of parts and dynamic assembly flowcharts flowed slowly through his mind like a data stream, with every detail clearly visible.

He didn't even need to think about it; he had already fully grasped its core principles.

"Theory without practice is never enough; let's put it into practice."

Lin Yuan smirked and directly exchanged a large amount of refined iron, black iron, and a complete set of crafting tools from the system shop using cheap points.

The quality of these materials far surpasses that of the ordinary iron found in the blacksmiths' shops of Nottingham.

Under the system's precise guidance, Lin Yuan's hands moved so fast that they almost left afterimages.

In his hands, pieces of hard, refined iron seemed to transform into soft clay, being rapidly cut, polished, and shaped.

Parts, each with a precision comparable to those produced by top-of-the-line machine tools in his previous life, were taking shape on his workbench at a speed visible to the naked eye.

Smelting, forging, quenching, assembly...

The entire process was smooth and efficient, without a single wasted effort or mistake.

In less than an hour, a Zhuge Divine Crossbow, entirely black with a cold metallic sheen, appeared perfectly in his hands.

Lin Yuan picked up the crossbow, skillfully filled the quiver with sixteen armor-piercing bolts produced by the system, and gently pressed the trigger against the hard wall of the dormitory.

"Whoosh whoosh whoosh whoosh!"

A series of rapid, teeth-grinding whistling sounds suddenly rang out!

Sixteen dark iron crossbow bolts instantly transformed into sixteen deadly streaks, piercing the wall made of hard stone bricks!

The arrow's tail was still buzzing from the immense kinetic energy, and the entire wall seemed to tremble slightly from the impact.

Lin Yuan played with the deadly weapon in his hand with satisfaction, a disdainful sneer appearing on his face.

"Tang Clan's hidden weapons are nothing special."

He spoke softly, his voice filled with utter contempt.

"Tang San, Tang San, the things you are so proud of, the things you cherish, and the things that require countless efforts to make, I can easily learn and perfectly replicate in just one night."

"Your trump card is worthless in my eyes."

The atmosphere in Notting College's practical classes is always very lively.

Today's lesson will showcase the tools that the students made themselves to aid in combat.

When it was Tang San's turn to demonstrate, he took a deep breath, his face showing barely suppressed pride. He took out an intricate mechanism strapped to his forearm from his pocket.

"Teacher, classmates, this is a hidden weapon that I researched and made myself. I call it a 'sleeve arrow'."

As he spoke, he raised his arm, aimed at the target in the distance, and a thought crossed his mind.

"call out!"

A short arrow shot out from the sleeve and hit the bullseye precisely!

"Wow!"

The whole class gasped in amazement.

"That's amazing!"

"Wow, that's fast!"

The instructor also stepped forward, picked up the hidden arrow, examined it carefully, and nodded repeatedly in praise: "Excellent, Tang San, this design is ingenious, the concept is unique, and it's very creative! Did you complete it independently?"

Hearing his teacher's praise, Tang San's gloom vanished, replaced by a surge of pride from being recognized. He straightened his chest and replied:

"Yes, teacher, I figured it all out myself, little by little."

He lied.

But he didn't think it was a lie; the Tang Clan's secret techniques were his own!

The entire class looked at him with envy and admiration, which greatly satisfied his vanity.

However, at that moment, an untimely voice poured down like ice water.

"Tang San, are you sure you designed this hidden weapon yourself?"

The one who spoke was Lin Yuan, who was sitting in the corner.

He slowly stood up, a playful smile on his face.

Tang San's heart skipped a beat, and an ominous premonition surged into his mind.

He forced himself to remain calm and looked at Lin Yuan, saying, "Teacher Yu, what do you mean by this? Of course, I came up with this myself!"

Lin Yuan sneered. His voice wasn't loud, but it carried clearly throughout the entire classroom.

"Really? Then why is your 'sleeve dart' exactly the same as the hidden weapon used by an ancient sect I know called the 'Tang Clan'?"

Tang Sect!

The moment those two words were uttered, Tang San's face turned deathly pale!

How did he know about the Tang Clan?!

Lin Yuan ignored his shocked expression and continued speaking eloquently: "The Tang Clan, a sect renowned for its hidden weapons and poisons hundreds of years ago. Their hidden weapon techniques are exquisite, emphasizing 'silence and stealth, killing without a trace.' Your sleeve dart, in both its mechanism and the arrow's firing principle, is a complete replica of one of the Tang Clan's basic hidden weapons. If I'm not mistaken, its trigger should be hidden in your middle finger joint, activated by the bending of the finger bone, right?"

As Lin Yuan spoke, he slowly walked to the podium, picked up Tang San's hidden arrow, and disassembled it in a few quick movements, clearly displaying its internal structure to everyone. His skillful technique made it seem as if he had made it himself.

"Look everyone, this transmission gear, this arrow storage groove, and the strength of this spring... they are all classic works of Tang Clan techniques."

The whole class erupted in uproar!

The gazes of everyone shifted from admiration to doubt and disdain.

Tang San's lips trembled, and his mind went blank.

He just couldn't understand why anyone in this world, in this plane, would know about the Tang Sect!

And they know it so clearly!

"I...I just...referenced some ancient books..." Tang San tried to explain, but his voice was dry and weak.

"Oh? An ancient book?"

Lin Yuan's smile grew even more sarcastic. "Then could you please bring out that ancient book and let everyone see it? As far as I know, the Tang Clan's hidden weapon blueprints are never circulated outside. Where did you get your reference from?"

Lin Yuan pressed on relentlessly, giving Tang San no chance to catch his breath.

He changed the subject and took something out of his own soul tool.

"It's quite a coincidence, I also have a good understanding of hidden weapons. This is a little gadget I made by imitating the Tang Clan's 'Zhuge Divine Crossbow'. You can see that its design principle is the same as Tang San's 'Hidden Arrow'."

He placed the Zhuge Crossbow he had made on the podium.

The crossbow's body was entirely black, its mechanism was intricate, and its arrows exuded a chilling aura... In terms of both craftsmanship and design, it was far superior to Tang San's crude sleeve arrow!

If Tang San's is a model, then Lin Yuan's is a real weapon!

Now, no one doubted it anymore.

"So it was copied!"

"I knew it! How could a part-time student like him design something so ingenious?"

"It's shameful to plagiarize and then claim it as your own original work."

The students' chatter was like steel needles, piercing Tang San's heart.

The instructor's face also turned extremely grim. He sternly stared at Tang San: "Tang San! What exactly happened? The academy has always valued students' originality and absolutely forbids plagiarism!"

Tang San stood there, surrounded by disdainful, questioning, and mocking gazes, unable to defend himself.

He felt a burning sensation on his cheeks, as if he had been slapped countless times in public.

His prized Tang Clan martial arts have now become irrefutable evidence of his plagiarism!

His reputation is ruined.

[Ding! Tang San's emotional value has been detected as -60. You have gained 5000 points for tormenting Tang San!]

[Ding! Tang San's social status has decreased, and his protagonist aura has been weakened by 10%!]

[Ding! Tang San's corruption level +3%, current corruption level: 27%!]

Tang San kept his head down, and no one could see the expression hidden in the shadows.

His fists clenched so tightly they cracked, his nails digging deep into his palms until they bled.

An unprecedented sense of humiliation and resentment began to fester in his heart.

"Yu Xiaogang...why did you do this to me? Why did you destroy everything I have?"

"I will definitely get my revenge... I swear!"
