173: The Black-feathered Eagle mutates, and the Three-Eyed Clan locks onto the secret realm.

"Alright, let the production lines run at full speed and activate 'troop-spam' mode!"

Lin Xingyu nodded, giving his instructions.

They now had abundant Materials, fully capable of sustaining such consumption.

After speaking, he began to check the information of Wang Ledian and the other person.

After their promotion, they only strengthened their existing abilities and did not acquire any new ones.

Just then, Morin hurried over, bowing to report:

"Sir, the combat mecha production line has been fully assembled!"

These production lines were of utmost importance, and he had always prioritized this task.

Now, the manufacturing center had begun to take shape.

Numerous factory buildings had sprung up, and supporting facilities were also complete.

"You've done very well. From now on, operate the production lines at full capacity!"

Lin Xingyu patted Morin's shoulder, telling him to also activate "troop-spam mode."

If all went well, he would soon reach Rank Five, at which point he would enter the Otherworld Battlefield.

To prepare for the upcoming battles, he needed to stockpile as many troops as possible.

"Yes, Sir!"

Morin accepted the order and left.

Lin Xingyu turned his gaze to the side of the heavenly spirit tree, where goblins were gathered, devouring spirit shaping fruit.

These were all selected technical backbone personnel.

Once they raised their spirit seed to SSS Rank, the technological development speed of the Inner World would advance by leaps and bounds.

"Brother Yu, what's that red fruit for?"

Wang Ledian leaned over, pointing at the marrow-shedding fruit and asking.

They had fought fiercely with the foreign beasts for half a day and still didn't know what the fruit was for.

To attract so many foreign beasts to guard it, it must be extraordinary.

"Oh, this is a marrow-shedding fruit. It can..."

Lin Xingyu informed everyone of the information provided by the System.

He had just acquired this item and hadn't had a chance to test its effects yet.

"Can the Black Plume Eagle eat it?"

Wang Ledian's eyes lit up.

He wanted the Black Plume Eagle to try it and see what kind of mutation it could undergo.

As his Rank increased, he started to feel a bit dissatisfied with the Black Plume Eagle.

Its abilities were too ordinary, only useful as a mount.

Looking at the Dark Fiend Dragon again, it could not only serve as a mount but also had exceptionally powerful attack capabilities.

It even possessed the ability to become invisible, making it a true "jack-of-all-trades."

This made him incredibly envious.

Even if it couldn't compare to the Dark Fiend Dragon, the Black Plume Eagle was still slightly inferior to Jin Yaotian's Griffin.

At least the Griffin's appearance was more majestic and handsome.

Seeing Lin Xingyu nod, Wang Ledian immediately picked a marrow-shedding fruit and blew his whistle.

Before long, the cry of a Black Plume Eagle came from the sky.

"Screech—"

A black shadow circled down, landing steadily beside the group.

The Black Plume Eagle squinted at Wang Ledian, its eyes full of disdain.

But the next second, it was attracted by the fruit in Wang Ledian's hand.

It instinctively sensed that this fruit contained energy beneficial to itself.

It immediately adopted a fawning expression, affectionately rubbing its large head against Wang Ledian and emitting low chirps.

"Haha, Old Dian, it really is the eagle you raised; its temperament is just like yours!"

Seeing this scene, Wang Chiyao immediately couldn't hold back, laughing so hard she bent over.

The Black Plume Eagle's cheeky demeanor was exactly like Wang Ledian's.

"Eat it, let's see what you can turn into!"

Wang Ledian's face darkened, but he still tossed the fruit over.

The Black Plume Eagle caught the fruit in its beak and swallowed it in one gulp.

In an instant, a powerful energy fluctuation erupted from its body.

Its dark feathers fell out one by one, and a faint dark-red energy flowed beneath its skin.

"Screech—"

The Black Plume Eagle let out a painful shriek, its massive body prostrating on the ground, trembling violently.

Before long, its body suddenly shook, and a wave of heat spread out from its center.

Feathers infused with flames rapidly grew, covering its entire body in no time.

"Nice, this look is much cooler!"

Seeing the Black Plume Eagle's new appearance, Wang Ledian immediately beamed with joy.

This look was far more impressive than Jin Yaotian's Griffin.

"Can it still be used as a mount? Won't it burn your butt!"

Wang Chiyao covered her small mouth, her face full of disbelief.

This change was too drastic!

She was even envious.

"The name has changed..."

Lin Xingyu began to check the Black Plume Eagle's information.

Its name had already changed to "Crimson Flame Eagle," and its attribute had become fire-attributed.

Additionally, it gained a new skill to launch fireballs, finally giving it a long-range attack method.

"Haha, again!"

Wang Ledian picked another marrow-shedding fruit and handed it to the Crimson Flame Eagle.

He planned to use it like the spirit shaping fruit, hoping it would refresh to a top-tier Bloodline.

However, this time the Crimson Flame Eagle did not take the fruit; instead, it let out a series of chirps at Wang Ledian.

"Alright, then eat it another day."

Although Wang Ledian was unwilling, he still put away the marrow-shedding fruit.

The Crimson Flame Eagle had just conveyed that it needed some time to stabilize its Bloodline before it could consume another one.

"Give it to me, I'll try too!"

Wang Chiyao took the marrow-shedding fruit from Wang Ledian's hand and immediately summoned her own Black Plume Eagle.

She also wanted to give it a try... Meanwhile.

In the Three-Eyed Clan World, Wind Taming City.

This city, built atop a mountain peak, was famous for its training of flying mounts.

Near Wind Taming City, several Secret Realms were distributed, inhabited by a vast number of flying foreign beasts.

Among them were many species that could be tamed as mounts.

Inside a hotel, the top five Geniuses from the Genius Battle were accommodated here, making their final preparations for refining the Secret Realm.

Lin Xingyu's Apostle, Baron, as the first-place winner, was arranged in the best room in the hotel.

At this moment, inside Baron's room, staff members were meticulously explaining the upcoming precautions.

"This time, what we are going to refine is the nearby Goshawk Secret Realm, inside..."

"The magical array is currently being inscribed, and the refinement will officially begin in five days."

"The method for refining the Secret Realm has been sent to you, you must..."

"The moment the secret realm core appears, refine it immediately; do not hesitate!"

"Especially you, as the first-place winner, you will be the first to attempt it."

"After successful refinement, bring out the secret realm core and hand it over to..."

After explaining all matters, the staff member placed a contract on the table.

"The contract is here; you have one night to consider it. I will come to collect it tomorrow!"

...Watching the staff member's retreating back, Baron fell into deep thought.

He had heard of the Goshawk Secret Realm.

It was home to a large number of Goshawks, which were extremely high-quality flying mounts.

They were not only powerful but also possessed excellent flying abilities.

This made it difficult for Three-Eyed Tribesmen of the same Rank to capture them.

For such foreign beasts, successful capture usually required someone of a higher Rank to act, relying on overwhelming strength.

However, due to the Secret Realm's restrictions, higher-Rank individuals could not enter.

The reason the Three-Eyed Clan had set their sights on the Goshawk Secret Realm was precisely the hope that after controlling the Secret Realm, they could lift the Rank restrictions.

They aimed to transform it into a base that continuously supplied flying mounts.
