I gain permanent defense when attacked; even gods and demons can't hurt me.

[Skill Roll: Giant Heart]

[Effect: After learning, you will master the skill "Giant's Heart". When activated, your health is doubled for 30 seconds! Cooldown: 10 minutes.]

Holy crap!

Lin Yuan couldn't help but swear.

Double defense! Double health!

Although it has a limited duration, it can be surprisingly effective in certain situations!

He hadn't forgotten that during this trip to the Azure Island, one of the enemy's shield warriors possessed a skill called Ultimate Defense.

After using it, its defense increases greatly, making it incredibly tanky!

Su Ya smiled as she looked at Lin Yuan's naive and unworldly demeanor: "The combined market value of these rewards is at least over one hundred million."

"Moreover, it's expensive but unavailable."

"In addition to these material rewards, there is also the corporal rank you earned when you enrolled."

Suya took out an exquisite medal and placed it on the table.

It was a black metal badge engraved with a crossed sword and shield.

Su Ya said seriously, "In the War Academy, military rank is a privilege. You can use it to exchange for some rare resources that cannot be obtained with points."

"For example, high-level skill books, entry qualifications for special secret realms, etc."

"Moreover, your military merits have increased significantly since this trip to Azure Island, and you're not far from being promoted to sergeant."

Lin Yuan happily put away the medals and the scroll.

This trip was worthwhile!

however.

Just as he was about to get up and say goodbye.

Su Ya suddenly called out to him, a meaningful smile on her face.

"By the way, Lin Yuan, the freshmen military training is in a few days."

Su Ya tapped her fingers lightly on the table and said casually, "I discussed it with Master Mo, and given that your strength is already far beyond the standard, participating in the freshman military training would be a waste of time, or even bullying."

"Therefore, we have decided to appoint you as an instructor, with generous military rewards as well."

"???"

Lin Yuan was stunned, then pointed to himself: "Professor Su, you're not kidding, are you?"

"Me? The drill instructor?"

"I'm a freshman too!"

"Is it appropriate for me to reprimand my classmates?"

Su Ya smiled dismissively: "What's inappropriate about it? This is the Academy of War, where the strong are respected."

"Don't you even look at your own rank?"

Su Ya pointed to the badge on Lin Yuan's chest: "He's already a corporal. Do you know what rank those instructors who train freshmen are?"

"Most of them are sergeants, and a small number are second-class sergeants."

"Among them are some third- and fourth-year students, who are all at the level of second-graders."

Speaking of it.

Su Ya leaned forward, her beautiful eyes fixed on Lin Yuan, her tone clearly provocative: "What? Lin Zhuangyuan, who just killed a level 45 boss without batting an eye?"

"Now that I'm sending you to mentor a few newbies, are you going to chicken out?"

The two were very close.

Lin Yuan could even see Su Ya's long eyelashes and her voluptuous breasts that were barely contained by her tight military uniform.

"Cough cough"

Lin Yuan blushed and subconsciously turned his head away, leaning back strategically: "Um... what's there to be afraid of?"

"So what if I'm an instructor! Who's afraid of who!"

Lin Yuan grabbed the things on the table somewhat awkwardly: "It's nothing, Professor Su, I'll be going now!"

Done.

He fled as if chased by a raging flood. Author Xiaopang's latest work, "Permanent Defense Increased When Hit, Even Gods and Demons Can't Damage Me," is exclusively published on Cola Novels!

Watching Lin Yuan's slightly flustered figure disappear through the door.

in the office.

Su Ya couldn't hold back any longer and burst out laughing, her laughter shaking her whole body.

She shook her head helplessly, her eyes full of laughter:

"It seems... no matter how strong he is, he's still essentially a hot-blooded, innocent young man."

Lin Yuan's room in the student dormitory.

Lin Yuan locked the door and let out a long sigh of relief.

"That woman is a real enchantress."

He patted his slightly flushed cheeks, quickly calming himself down.

"Never mind that, getting down to business is the priority!"

Lin Yuan sat cross-legged on the bed and took out all four skill scrolls.

First, there are those two specific rolls.

Congratulations! You have successfully learned the skill: Titan's Wall!

Congratulations! You have successfully learned the skill: Giant Heart!

As the two beams of light entered his body, Lin Yuan successfully completed his training.

He's planning to go to the secret realm again tomorrow, so he can upgrade his newly acquired skills then.

The longer he stays at level 25, the more defense points he gains.

Of course, there is a limit to how long one should stay.

After all, there must be higher-level dungeons and secret realms in the academy, but those also have level requirements, such as needing to be level 30 to enter.

Therefore, he doesn't need to stay at level 25 for too long. Perhaps he can break through to level 30 after the freshman military training is over.

Next up is the main event: two random intermediate skill scrolls.

"Luck is also a part of skill; hopefully, I'll get something good."

Lin Yuan took a deep breath and tore open the first scroll. A dazzling golden light instantly shone out!

[Invincible Barrier (Unique)!]

[Effect: This skill is exclusive to the "Unbreakable Barrier" skill tree. Upon activation, the user enters an "Absolute Invincibility" state, immune to all damage (including true damage) and control effects! Lasts for 1 second. Cooldown: 1 hour. Mana cost: 200 points]

"Holy crap?!"

Upon seeing the skill description, Lin Yuan jumped right out of bed.

"Invincible skill!!"

"And it's absolutely invincible, immune to true damage!"

Lin Yuan was so excited that his hands were trembling.

He had learned in his textbooks that ordinary invincible skills, such as the mage's [Ice Barrier] and the knight's [Divine Shield], although they are called invincible, will still cause damage when faced with high-level true damage.

But this skill... clearly states that it includes true damage!

"Cool!!"

"This is so awesome!!"

"I was just worried about not having a way to defend against true damage. If I had this move when I fought Wilson, I wouldn't have even lost those 20,000 HP!"

Although it only lasted for a short 1 second.

But for a master, as long as the timing is right, one second of invincibility is enough to decide life or death!

"Again!"

Lin Yuan eagerly tore open the second scroll.

【Holy Resurrection】

Looking at this skill, Lin Yuan couldn't suppress the smile on his face.

"A healing skill!"

"Still a percentage-based instant health recovery!"

If an ordinary person saw "10-minute cooldown" and "costs 200 mana", they might think that this skill can only be used as a last resort to save their life.

But who is he?

It possesses the gold-tier keywords: [Endless Barrier] and [Source of Mana]!

He can heal himself indefinitely if he wants!
