Although this boy named Ruby only displayed the combat power of an early-stage Great Knight, there was one thing that made him cautious.

Throughout the entire encounter, the young man never drew his sword, only using a dagger and short knife against his opponent, but the sword at his opponent's waist was definitely not just for decoration.

Out of caution, he sent out Stav, the third strongest among his own students.

With full power, he can reach the strength of a late-stage Grand Knight!

"Dark Higher School, Stav!"

The boy proudly announced his name, his emerald green eyes fixed on the ruble, and his arm gripping the spear gradually tensed.

"Dragon Territory, Academy, Scholarly Family, Ruble!"

The boy opposite him put pressure on him, and Ruble's gaze turned serious as he gripped the hilt of his sword.

This is the sword the principal gave him that day.

"Little Ruble, you're the one I value most in the entire academy, even though your talent isn't as great as many others. But what is genius? Genius is 1% talent plus 99% perspiration. Your diligence moves me, and I believe you can become the most powerful genius in the academy!"

"You may have some secrets in your heart. You can share them with Grandpa Principal. If you don't want to talk about them now, that's okay too. Don't suppress yourself too much. Remember, the college and Grandpa Principal are your strongest support."

At that time, Su Qing's words were so sincere and heartfelt, showcasing her acting skills to the fullest.

The boy's eyes reddened as he was being persuaded, which truly moved Ruble, and he even had an urge to tell him the secret.

It was around that time that this silly boy finally felt a sense of belonging to the Dragon Territory.

...

"I have a unique sword technique here, and you are destined to learn it from me today!"

He recalled the scene when Su Qing taught him swordsmanship.

Ruble tightened his grip on the sword hilt.

...

"This sword technique is different from other sword techniques. It is called the Sword Nourishing Technique. From today onwards, this sword must not be drawn. It must be carried close to your body every day, even when sleeping and eating. You must also use your battle qi to nourish this sword for two hours every day."

"Thirty days is enough for you to enter the realm of swordsmanship; one hundred days is enough for you to achieve minor mastery; three hundred days is enough for you to achieve major mastery; and as for perfection, that's a realm you'll never reach in your entire life!"

The thirty-day introductory period has long been completed.

The reason I haven't drawn my sword is that I haven't encountered an opponent worthy of it.

Although the young Stav before him was somewhat lacking in skill, he felt that he was no match for him if Stav didn't draw his sword, which could be considered as forcing him to draw his sword.

The instant Ruble announced his name, Stav's spear was already launched.

This shot was like a silver snake!

A surge of battle aura gathered at the tip of the spear, powerful and swift as lightning. At the same time, a strange fluctuation spread from some silver patterns on the spear.

This gun is a magical artifact, imbued with magical runes.

Strictly speaking, this is against the rules, but just like the magic cannon Su Qing took out earlier, it wasn't explicitly prohibited.

At that moment, Ruble also drew his sword.

After nearly fifty days of nurturing, this sword now unleashed its brilliance.

The silver sword light that lit up the sky was nearly ten meters long, and its power directly entered the level of a high-ranking knight.

The gun shattered, leaving a deep trench in the ground. Young Stav froze, the afterimage of the sword light still lingering in his pupils.

Silence fell over the room.

Everyone watched as the young man silently sheathed his sword and slowly walked back to the platform.

"This sword strike wasn't his usual power, was it?"

Dean Qinghe, who was standing next to him, couldn't help but ask, "Can a peak-level formal knight really unleash strength comparable to a high-ranking knight? That's a lie!"

"Of course not!"

Su Qing casually replied, "Indeed, if Ruble were to unleash another sword strike, the power would definitely not reach this level. It would probably drop by one or two minor realms, meaning it could only unleash the peak strength of a Great Knight. Well, that's pretty abnormal!"

However, its drawback is also obvious: it can only make one strike.

After unleashing this sword strike, one's energy and spirit will completely wane.

Therefore, the sword technique that Su Qing passed on to him is called the Sword Nourishing Technique, and also known as One Sword Overturns the Heavens.

It belongs to one of the many sword techniques in one's mind, and its level is above average.
