Nightmare World's current level cap is 40, and Fourth Rank Lords have been stuck at this threshold for many years.

If the Apostle's strength is above level 50, that's no longer a gap that numbers can bridge.

He shook his head; with too little information, guessing was useless.

Once the Great Wall is built, he'll have enough confidence to have a showdown with Director Zhou.

When the time comes, by combining the intelligence from Fenghuo County with the General Bureau's ninety years of data, perhaps the true face of the Black Tide can be pieced together.

He was about to say something when a dull sound suddenly came from behind him.

Rumble! The high platform collapsed!

In its original place, a downward stone staircase was revealed, and at the end of the stairs was a semi-transparent light screen with seven characters written on it. 𝑓𝘳𝑒𝑒𝓌𝘦𝘣𝘯ℴ𝑣𝘦𝑙.𝘤𝑜𝑚

【Dungeon Level Six Entrance】.

Beside the light screen, a purple treasure chest appeared out of thin air.

The chest had a curved lid, its surface carved with intricate patterns that faintly shimmered with flowing light.

It was exactly the same as the treasure chest inside that hidden cave on the first floor.

"A treasure chest! A purple one!"

Tie Dun was the first to rush over. He squatted in front of the chest, rubbed his hands together, and glanced back at Lin Feng.

He swallowed hard and didn't dare lift the lid. Instead, he stood up, took two steps back, and scratched his head with a foolish grin.

"Lord, I don't dare open this treasure anymore. If I do, it'll probably be another Amethyst, wasting this purple chest. You do it, you do it!"

Lin Feng smiled and didn't decline, walking up to the treasure chest.

Everyone gathered around.

Zhao Hu stood behind Lin Feng with his arms crossed; Wang Wu and Arrow Eye were on his left and right, and Su Yurou held the bone healing staff.

Jiang Yelan stood at the edge of the group, her shadow moon blade hanging at her waist. Her cloak's hood was down, revealing her cold face.

Lin Feng squatted down, placed both hands on the lid of the treasure chest, and flipped it open with force.

A burst of purple light appeared—not a faint lavender, but a thick, dazzling radiance, like a small purple sun exploding.

The light lasted for about two seconds before receding, revealing a booklet lying quietly inside the chest.

The cover of the booklet wasn't bronze but deep purple, embossed with silver-white characters—"Shadow Walker."

Tie Dun's eyes widened into circles, his mouth formed a large 'O', and his voice even changed pitch.

"A... High-grade Class Change Book? And it's rare! My goodness! Lord, your luck is just too heaven-defying! You get a High-grade Class Change Book on your first try! Your Lucky King constitution is something an Unlucky Chieftain like me really can't compare to!"

Zhao Hu took a deep breath and said solemnly, "There are barely any High-grade Class Change Books in all of Great Xia. Lord, your luck..."

Although Arrow Eye didn't speak, his fingers froze on the bowstring, and his whole body seemed to be rooted to the spot.

Su Yurou covered her mouth, her eyes curving into crescents: "Lord, I'm truly impressed."

Jiang Yelan said nothing.

Her body leaned forward slightly, her gaze fixed intently on that deep purple booklet.

Her breathing stagnated for a moment, and her heart gave a heavy thud in her chest, then another.

A High-grade Class Change Book, and not just any high-grade, but the rare Shadow Walker—an advanced class for Assassins and the one most suited for her.

Lin Feng picked up the booklet, flipped open the cover, and the attribute panel expanded before his eyes.

【High-grade Class Change Book · Shadow Walker (Rare)】

Base bonuses after class change: agility +30%, strength +30%, constitution +40%

Skill 1: Poison Blade Tempering (Passive) — When the holder's attack hits an enemy, it applies a poisoning effect: lose 50 health points per second for 6 seconds. This effect can trigger at most once every 60 seconds (enters cooldown after hitting the first enemy).

Skill 2: Phantom Flying Blade (Active, 20s Cooldown) — The holder throws a flying blade imbued with shadow energy. The Flight path is curved, with a maximum range of 300 meters, dealing 150% of attack power as damage.

Lin Feng sighed inwardly; he didn't even know where his own High-grade Class Change Book was, yet Ye Lan's had already been found.

But that was fine; after Ye Lan changed classes, she should be able to reach level 30 directly. With the agility bonus from the Shadow Strike Boots, breaking 60 agility was a sure thing.

Unlocking Flight, plus the Great Wall's 30% total attribute boost, it would be easy for her strength to break 60, officially becoming a member ~Nоvеl𝕚ght~ of Great Xia's high-end combat force.

From then on, she would no longer be just a blade hidden in the dark, but an assassin capable of fighting head-on in the sky.

He closed the booklet and turned to hand it to Jiang Yelan.

"Ye Lan, for you."

Jiang Yelan took the booklet, her fingers lightly stroking the deep purple cover.

Her lips parted slightly as if she wanted to say something—a thank you, or "Lord, this is too precious"—but the words were swallowed back down.

Having followed Lin Feng for so long, she knew he wasn't the type who cared for pleasantries.

She looked up at him, and for a fleeting moment, there was something rare and almost soft in her eyes, but it returned to its usual coldness in an instant.

Lin Feng smiled: "We've been fighting together for so long; some things don't need to be said."

She nodded slightly, her voice as flat as ever: "Okay."

Without another word, she tucked the High-grade Class Change Book into her robe and then bent down to pick up the pair of shadow walk boots she had just swapped out.

She turned and walked to Su Yurou, handing over the boots.

Su Yurou was stunned for a moment, then took the boots with both hands and cradled them in her arms.

The shadow walk boots were of blue quality, boosting agility and movement speed, which was exactly what she needed for her healer class.

"Sister Ye Lan, thank you!" Her voice carried unmistakable joy.

Jiang Yelan waved her off, stepped back a few paces, and took out the deep purple booklet from her robe.

She took a deep breath, bit her fingertip, and dripped blood onto the cover.

A dark purple light surged from the pages, enveloping her entire body.

Within the light, her figure grew slightly taller, her shoulders seemed a bit broader, her waist thinner, and her legs more slender.

【Class Change Successful!】

【Class: Shadow Walker (Rare)】

【Level: 29 → 30】

The light receded.

Jiang Yelan reappeared before everyone, her aura completely different from before.

Colder, heavier, more like a blade that had been polished of all its rust.

She looked down at her hands, lightly clenched her fists, and then kicked off the ground. Her body soared upward, hovering in the air five meters above the hall floor.

Flight! agility has broken 60!

Tie Dun looked up, his mouth wide enough to fit a fist: "Ye Lan is flying! Ye Lan can fly too! My goodness, when she plays as an assassin in the future, she won't be stabbing from behind, but from the top of the head down!"

Wang Wu said, "Congratulations, Ye Lan."

Zhao Hu also smiled and nodded.

Arrow Eye finally spoke, uttering two words: "Impressive."

Su Yurou held her bone healing staff and looked up at Jiang Yelan in the air, unable to suppress the smile on her face.
