I Became an Academy Overpowered Growth Genius – 139

EP.139 The Growth Genius (2) [End]

After fully conquering the Tower, Kang Seo-jun began preparing for the great invasion of demons by doing everything he could. The first priority was to complete his ‘personal combat power.’

As soon as he exited the Tower, Kang Seo-jun purchased the 《Dimensional Rift Mana Spot – Tomb of the Outer Gods》 from the dimensional shop and focused solely on leveling up there. Whenever [Mythic] grade or [Transcendent] grade gates appeared, he would enter them alone and finish farming before the Hunter Alliance or the government could even react.

By monopolizing all trials and rewards for a year, he finally achieved it.

‘The Ultimate Return… complete.’

After about a year of training, Kang Seo-jun had become something beyond a ‘god’… something that even transcended gods.

Now, his physical body was strong enough to overpower ten One Punch Men simultaneously, and his mana was exponentially greater than all the mana in the universe combined.

‘It wasn’t easy… but I managed somehow. It went pretty smoothly.’

As he had initially aimed, Kang Seo-jun succeeded in completing the most powerful tech tree in history. His current specs were beyond the realm of common sense and balance, stronger than all the characters he had ever played combined.

‘But the preparations aren’t over yet.’

To ‘perfectly’ protect Earth from the ‘Great Invasion of Demons,’ there was still a mountain of tasks to complete. Normally, he would have needed the active help of heroines or companions. However…

‘With these specs, I don’t need the power of heroines or companions.’

With nearly infinite power, mana, and dimensional currency, Kang Seo-jun could single-handedly face the great armies of the demon realm.

‘It’s like having an infinite resource cheat and preparing for defense.’

Kang Seo-jun opened the dimensional shop and began purchasing items necessary for the Great Invasion of Demons.

[Thank you for using 《Multiverse Real Estate》!]

[Thank you for using 《Multiverse Secondhand Shop》!]

.

.

[You have purchased 《Flying Fortress of Kang Seo-jun from the 54th Round》!]

[You have purchased 《Space Battleship of Kang Seo-jun from the 66th Round》!]

First, he bought flying fortresses and space battleships to mercilessly bombard the swarming demon mobs.

[You have purchased 《Golem Factory of Kang Seo-jun from the 72nd Round》!]

Next, he bought a factory to mass-produce golems that would fight the demons in place of powerless hunters.

[You have purchased 《Giant Mecha of Kang Seo-jun from the 35th Round》!]

He also bought giant mecha robots that could be flexibly operated depending on the situation.

[You have purchased 《Constellation Summoning Circle of Kang Seo-jun from the 88th Round》!]

And a shrine to summon constellations that would toy with high-ranking demons that appeared intermittently.

Finally…

[Using the trait 《Authority of Projection Lv. Transcendent》.]

[You have duplicated 《Flying Fortress of Kang Seo-jun from the 54th Round》!]

[You have duplicated 《Space Battleship of Kang Seo-jun from the 66th Round》!]

[You have duplicated 《Golem Factory of Kang Seo-jun from the 72nd Round》!]

[You have duplicated 《Giant Mecha of Kang Seo-jun from the 35th Round》!]

[You have duplicated 《Constellation Summoning Circle of Kang Seo-jun from the 88th Round》!]

.

.

He used the 《Authority of Projection》 to duplicate everything he had purchased dozens of times.

—

With these preparations, Kang Seo-jun stood ready to face the Great Invasion of Demons, ensuring Earth’s safety with his overwhelming power and resources.

‘Perfect…’

The purchased fortresses and factories were well hidden in dimensional rifts and underground to prevent any troublesome issues from arising.

‘Next is…’

The equipment setup he had been postponing.

[You have purchased the Transcendent grade helmet 《Union of the Sun Gods》.]

[You have purchased the Transcendent grade chestplate 《Divine Blood Stagnant in the Void》.]

[You have purchased the Transcendent grade armguards 《Essence of the Martial Gods》.]

[You have purchased the Transcendent grade gloves 《Gauntlets of Infinity》.]

[You have purchased the Transcendent grade greaves 《Rags of the Betrayers》.]

[You have purchased the Transcendent grade boots 《Form of Freedom》.]

.

.

[You have purchased the Transcendent grade longsword 《Radiance》.]

[You have purchased the Transcendent grade greatsword 《Judgment》.]

[You have purchased the Transcendent grade magic staff 《Fate》.]

[You have purchased the Transcendent grade colossal sword 《Genesis》.]

.

.

Even with nearly infinite dimensional currency, setting up all equipment and weapons to [Transcendent] grade was nearly impossible. However, for Kang Seo-jun, who could duplicate dimensional currency as much as his mana allowed using the 《Authority of Projection》, it was just a matter of time.

‘Now then….’

Having thoroughly prepared defenses against the Great Invasion of Demons and fully equipped himself with [Transcendent] grade items from head to toe, all that was left was…

‘Just waiting.’

Until the day of the Great Invasion of Demons, Kang Seo-jun quietly spent his time duplicating dimensional currency.

Two weeks later.

The countdown that had started when he finished conquering the Tower ended, and the invasion of demons began. However, the final chapter ended swiftly and silently due to Kang Seo-jun’s rapid response.

In just one hour.

That was the time it took for Kang Seo-jun to eliminate every single demon pouring through the dimensional rifts.

When a giant monster rose from the sea, he bombarded it with orbital strikes from the space battleships. When a giant emerged from an erupting volcano, he crushed it with the flying fortresses.

When demons poured out of the sky over the plains, they were swept away by the golem and spirit legions. Occasionally appearing [Demon Grand Duke]-level demons were personally cut down by Kang Seo-jun. Among the [Demon Lords], there were demons with the stature of ‘Constellations,’ but they couldn’t last even three moves against Kang Seo-jun, who had transcended multiple times.

After the battles, as always, he neatly converted all the corpses into dimensional currency. The damaged or polluted natural landscapes were also swiftly restored using spirit magic and his immense mana.

Thus, the world achieved perfect peace. The conditions for the perfect happy ending that Kang Seo-jun had longed for were fulfilled. On the news that day, only reports of high-magnitude earthquakes occurring worldwide were mentioned; no other special news was reported.

Two years had passed since the Great Invasion of Demons. With all the battles over, Kang Seo-jun focused on stabilizing his harem.

Jin Se-rin, the young lady of the Seongjin Group,

Seo Eun-ha, Jin Se-rin’s attendant,

Park Seo-yoon, the leader of the Taesan Guild,

Lim Chae-won, the heir to the Gangwon Guild,

Kim ju-hee, the instructor at the Academy,

Sakura, the hound of the Kuyamoto clan,

And many others…

The oldest progenitor vampire, the daughter of the Russian Thunder Emperor, the Golden Queen of the Middle East, the princess of England, the president of the Hunter Union, the twin sisters of the Chinese Huanglong Group, the goddess sealed in the Hidden Dungeon of Antarctica, the genius girl from the slums of South America, the leader of a secret organization, the young chieftain of an African beast tribe, the great spirit who reconnected with him across time and space, and so on…

Kang Seo-jun met and formed bonds with heroines scattered like Dragon Balls around the world. The number of heroines he gathered was a staggering 139!

Stabilizing the harem and mediating among all of them was no easy task. To gain permission for the harem from everyone, Kang Seo-jun used every means at his disposal. Sometimes, the records of fate were useful, and other times, he resolved issues with sincere persuasion and appeals.

In the process of stabilizing the harem, he also addressed the deficiencies and problems the heroines were suffering from. However, he strictly avoided any actions that would negatively impact the heroines’ mental or physical health, such as drugs, training, hypnosis, or brainwashing.

Initially, it was incredibly challenging, but as he succeeded in persuading one or two, it became easier with the help of the heroines. By relying solely on sincerity and truth, Kang Seo-jun succeeded in stabilizing the harem in about two years.

“Hey, hey! Kang Seo-jun!”

“Ah, Park Shin-hye. You’re late.”

“S-sorry…!”

“Don’t be late next time. Hurry to your spot.”

“O-okay!”

…And so, Park Shin-hye also became part of Kang Seo-jun’s harem. About six months ago, who would have thought that Park Shin-hye, unable to control her desires, would attempt to seduce Kang Seo-jun while he was sleeping? Afterward, Kang Seo-jun realized that her feelings were genuine and accepted her as a member of his harem.

Thus…

Today was the day of the cooking competition among Kang Seo-jun’s heroines. The teams were divided into groups of four, and the winning team would be rewarded with a night spent with Kang Seo-jun.

“Hey! Park Shin-hye! You’re late!”

“I-I said I’m sorry!”

“And why is your makeup so heavy?! The powder might fall into the food!”

“H-huh! Did you notice…?”

“Of course, I did!”

“Now, now. Ladies. Shin-hye. Please calm down. We don’t have much time left for the meeting. Let’s hurry up and start.”

“Ugh… Why do I always end up in a team with people who fight….”

“Come on! It’s not over yet! We still have a chance! Let’s do our best!”

Team 1 consisted of Jin Se-rin, Park Shin-hye, Seo Eun-ha, and Lim Chae-won.

“This time, we must win. Everyone, prepare to give it your all.”

“Of course. This time, I’ll give my five children a sibling!”

“Ha ha ha! You are lucky! If you fall into my hands, this competition will be over in an instant!”

“Stop eating the ingredients…!! How can you eat the meat meant for the main dish!”

“W-what…!?”

Team 2 consisted of Kim Joo-hee, Sakura, Park Seo-yoon, and the new member, the progenitor of vampires.

A total of 35 teams began the cooking competition with all their might to win a night with Kang Seo-jun.

‘This is the blissful life in another world…’

The warm sunlight.

The delicious aroma wafting through paradise.

The sound of heroines chatting happily.

Such happy times flew by quickly, very quickly.

The transcendent Kang Seo-jun and his heroines lived eternally, giving birth to countless children. These children became a new race, building a space empire alongside Homo sapiens. It is said that the golden age of Kang Seo-jun’s children and humanity, as a race of growth geniuses, never ended even after conquering the entire dimension.
