Card Kingdom: This kid's codex is full of gold

At this moment, Zhang Yun and the other two had already left the training hall.

The old headmaster suddenly stopped, turned to look at Zhang Yun, and said in a slightly stern tone, "Tell me honestly, why did you insist on killing Chen Wu's Silver Minotaur?"

"You've already achieved absolute excellence, so why did you have to resort to murder?"

Zhang Yun met the old principal's gaze and said frankly:

"I am simply giving them a taste of their own medicine."

"He had cursed at me at the school gate before, and because he saw me as a law student, he wanted to bully me."

"I didn't want to argue with him, but just now... he even tried to cripple my card beast. If I don't fight back, he'll only escalate his actions!"

"grandfather..."

Zhou Na tugged at the old principal's sleeve and pleaded, "Chen Wu was really awful, Zhang Yun was just acting in self-defense, please don't punish him!"

"Why should I punish him?"

The old headmaster glared at his good-for-nothing granddaughter and said irritably, "That lousy student Chen Wu only knows how to bully the weak. I want to punch him a few times just looking at him. Zhang Yun was able to kill his magical beast, I admire that more than anything. Why punish him?"

"Well..."

Zhou Na was completely stunned, never expecting the old principal to have such a face!

Zhang Yun was astonished to hear the old principal say such a thing, and looked at the old principal in disbelief.

The old headmaster glanced at him and asked in a calm voice, "Why are you looking at me like that?"

"You did the right thing, but you were too impulsive."

"Arrogant people usually have something to rely on. Chen Wu's reliance was his uncle, Chen Sheng."

"I have no problem with your quick revenge, but I hope you'll be more careful next time and investigate other people's backgrounds before you take action."

"Otherwise, you'll suffer a great loss sooner or later."

Upon hearing this, Zhang Yun suddenly realized what was going on.

No wonder I performed so well; not only did Teacher Chen Sheng not appreciate it, but he also chased after me like a mad dog...

It turns out they are family...

Seeing the principal's reminder, Zhang Yun was grateful and nodded in thanks: "Thank you for the reminder. I have learned my lesson and will be more careful in the future."

Seeing Zhang Yun's upright attitude, the old principal nodded in satisfaction, a smile appearing on his lips.

At this moment, Zhou Na asked worriedly, "Grandpa, Chen Sheng is so capable, won't he retaliate against Zhang Yun in secret?"

Zhang Yun said, "He's a teacher, surely he wouldn't?"

"Hard to say..."

The old headmaster shook his head and said in a deep voice, "In this school, I'm the one who calls the shots. No one dares to touch you without my permission."

"However, things might be different once you leave campus."

"Chen Sheng was also an excellent hunter in his early years. He knew many people in the underworld, many of whom were famous and powerful figures."

"You've destroyed one of his nephew's main card slots. He might not retaliate on his own, but he might if someone else does it."

Zhou Na panicked and tugged at the old principal's sleeve, asking, "Grandpa, what should we do? You have to help Zhang Yun! He's my trump card to becoming an excellent teacher!"

"What's the rush? Did I say I wouldn't help him?"

The old principal gave her a sidelong glance and said to Zhang Yun, "Zhang Yun, if you want to avoid retaliation, the safest way is to move into the school dormitory."

"There are security personnel and teachers on duty on campus, so it won't be so easy for him to do anything to you."

"With your abilities, you'll become famous in Jiangcheng sooner or later. Once you make a name for yourself, Chen Sheng won't dare to make things difficult for you."

Upon hearing this, Zhang Yun's lips twitched.

He's really got a terrible constitution; he just had a home invasion robbery last night and offended that ruthless thug, Old Scar.

Today, after dealing with a cute little girl, I've managed to provoke an even stronger Chen Sheng.

This luck is unbelievable.

Seeing that Zhang Yun did not respond, Teacher Zhou Na became a little anxious and tugged at his sleeve, advising, "Zhang Yun, just listen to my grandfather and become a boarding student."

"The teacher will help you apply for scholarships and spiritual resources to help you grow steadily."

"Be good, okay?"

"Okay... then."

Zhang Yun nodded helplessly, then bowed to the old principal and asked, "Principal, may I ask you a question...?"

"Ask whatever you want."

Zhang Yun carefully considered his words before asking, "Why are you so kind to your students? We're not related, are we?"

Upon hearing this, the old principal smiled.

He didn't mince words, saying frankly, "The reason I'm helping you is because I see your talent and potential."

"If I'm not mistaken, you must be Old Devil Zhang, right?"

"Yes!" Zhang Yun readily admitted.

He knew he couldn't hide his identity for long.

After all, the school is full of surveillance cameras. With just a little investigation, his identity can be easily uncovered, and he can't hide it at all.

"What does 'Old Devil Zhang' mean?" Teacher Zhou Na asked, tilting her head in confusion.

"Why are kids asking so many questions?"

The old principal gave her a disapproving look, then immediately changed his expression and smiled approvingly at Zhang Yun: "You're quite good, you have the makings of a genius."

"With a super genius like you at our school, it's only a matter of time before we crush Jiangcheng No. 2 Middle School."

"The reason I'm helping you is so that you can contribute to the school in the future and enhance our school's reputation."

Upon hearing this, Zhang Yun's lips twitched. Just as he had expected, the old principal was keeping him as a school thug...

But it doesn't matter. Being a school thug is fine. After all, he now has the old principal as a backer, so no one in the school will dare to make things difficult for him!

Seeing the old principal's candor, Zhang Yun naturally had to express his opinion as well.

He bowed deeply with humility, saying, "The principal has been kind to me, and I will always remember it."

"From now on, the student will definitely cultivate himself diligently and bring honor to the school!"

"Okay, okay, hahaha!"

Upon receiving Zhang Yun's endorsement, the old principal was overjoyed and clapped his hands repeatedly.

He hesitated for a moment, then smiled and said, "You can't go to Class S. Chen Sheng is a top-level teacher, and I can't dismiss him, lest he develop even greater hatred for you."

"You can stay in Class 10 from now on."

"I will have Teacher Zhou Na grant you the treatment that students in Class S are entitled to."

"If there is anything she cannot satisfy you, you can come to me, and I will solve it for you."

Zhang Yun didn't mince words and directly stated his request: "The student's code has already reached the fifth level of the cast iron level, and is not far from advancing to the bronze level."

"I wish to cultivate the Soul Technique as soon as possible, and I hope you can grant my request."

"You've reached level 5 in the first rank?!"

Zhou Na's beautiful eyes widened instantly as she looked at Zhang Yun as if he were a ghost. "Didn't you just awaken as a summoner when you enrolled? How come you've already reached the fifth stage of the first tier in just one month?"

"Many students spend two or three years carefully hunting wild monsters, and only then can they barely reach Tier 1, Rank 5!"

"How exactly did you cultivate?!"

At that moment, Zhou Na felt like she had been hit hard...

After all, it took her a full two years to upgrade from Cast Iron Stage 1 to Cast Iron Stage 5...

He also got injured quite a few times during that period...

It's infuriating to compare people like this...
