The Blood Pelican Demon Blade +10, while its appearance remained unchanged, gave off an even more magnificent feeling. Xu Lang gripped the hilt, a surge of killing intent rising in his heart, and the blade responded by shimmering with a sinister crimson aura, radiating a bone-chilling cold.

A weapon enhanced to +10 actually gave a sense of being connected to one's heart and mind!

The benefits this brought were far from just simple numerical increases.

"Lang Ge, I can't go on." Li Wenwen's little face was pale, her breathing slightly labored.

Xu Lang sheathed the Demon Blade and helped Li Wenwen sit down to rest.

The enhancement difficulty for the Blood Pelican Demon Blade was extremely high. Being able to reach +10 was entirely thanks to using Forging Essence as sacrificial material.

These were all accumulated bit by bit by Li Wenwen over time, and she had also poured immense effort into it herself.

Although Xu Lang was not a possessor of a Forging-type Sequence, hearing Li Wenwen say "I saw a pelican devouring living people in a purgatory" made him understand that the Forging Sequence was not as simple as it appeared to outsiders.

"+10 is more than enough, you've worked hard, Wenwen." Xu Lang looked towards Sherry.

Sherry immediately came over to treat Li Wenwen.

Don't think Sherry wasn't a combatant;relying on her Healing Spell, she had truly earned a lot of money. With the accumulation of funds, she had developed her own set of healing and support system, which was gradually taking shape.

After Li Wenwen recovered, Xu Lang took out a heart-protecting mirror. "Wenwen, this is for you."

Li Wenwen checked the mirror's properties and was instantly shocked. "This is so precious, I can't accept it!"

The heart-protecting mirror was actually a rare-grade life-saving item, extremely valuable.

"Let's keep things separate... and this isn't payment, it's a gift from me." Xu Lang's lips curved into a faint smile.

Life-saving items like this weren't lacking for Cao Yaxuan and the others either.

After all, he was the richest person in the entire Mad King Building. Many players, whether Pioneering or Floor Sweeping, would hoard any good finds they discovered because they'd be taxed or even plundered.

But they still wanted to exchange for resources, so what could they do?

They could only come to Xu Lang!

Floor Leaders would argue over "how do you have a specialty item from my territory," dragging the seller into the mess.

But once an item reached Xu Lang's hands, that was a different story!

No one dared to ask, "Xu Lang, did my place have a mole?" or "Xu Lang, how did something from my territory end up in your hands!"

Xu Lang was the biggest Black Market Merchant in the entire Mad King Building. Once something reached him, the trail went cold.

"Then I'll accept it..." Li Wenwen said sheepishly.

Xu Lang nodded, sat down beside Li Wenwen, and took out a blood diamond. "Take a look at this."

Sitting next to Xu Lang, Li Wenwen felt her body grow warm. Lang Ge was clearly an abstinent male god type, so why was her heart racing so fast? She was really being hopeless.

"This is a legendary Enchantment Gem!" Li Wenwen checked the blood diamond's information and was immediately utterly astonished.

[Blood Diamond]

[Type: Enchantment Gem · Turret]

[Rarity: Legendary]

[Effect: Turret shots will cause 20% chain damage to monsters of the same species within 30 meters]

[Description: A diamond forged from the Blood of Others, dazzling and brilliant. May the radiance of others' blood illuminate your turret.]

"What a terrifying effect!" Li Wenwen clicked her tongue in amazement, staring at Xu Lang in shock. "Lang Ge, where did you get this Enchantment Gem?"

Little girls were just little girls. If Li Shuwen were here, he definitely wouldn't ask such a presumptuous question.

Xu Lang replied nonchalantly, "You know about the Hunter Building players' ambush last time? I found it on them." 𝒻𝑟𝘦𝘦𝘸ℯ𝒷𝑛𝘰𝓋ℯ𝘭.𝘤𝘰𝘮

"So that's how it is." Li Wenwen understood, then said, "Lang Ge, this thing is priceless. You should keep it safe."

Because Enchantment Gems had no level, their depreciation rate was extremely slow. They were hard currency for transactions between players, sometimes even more useful than Copper Coins.

But Enchantment Gems also had a side effect: they attracted hatred.

Embedding a high-level Enchantment Gem increased the risk of being robbed.

A turret was useless once dismantled, but the Enchantment Gem embedded on it could be removed intact. If your strength was mediocre yet you possessed a top-tier Enchantment Gem, that was truly a case of virtue not matching position.

Xu Lang chuckled softly without speaking, gazing at the beautiful blood diamond, slightly lost in thought.

The blood diamond had no level. Many special items in the Mad King Building also had no levels.

But did that mean they absolutely could not be upgraded? Xu Lang didn't think so.

However, based on his superficial understanding of the Nightmare Lord Sequence, he probably hadn't developed it enough yet. Otherwise, given the bug-like nature of the Nightmare Lord, it should definitely be able to transcend those so-called rules.

"Keep it safe? In the Dorm Survival Game, you should use good things promptly." Cao Yaxuan poured a cup of cola for Li Wenwen, smiling as she imparted her experience.

Li Wenwen knew Cao Yaxuan had misunderstood and was about to explain when she suddenly remembered this was Dorm 200.

Even if all of Lang Ge's turrets were fully embedded with legendary Enchantment Gems, no one would dare to come rob him!

Seeing Li Wenwen somewhat flustered, Xu Lang changed the subject. "Which turret do you think this blood diamond should be embedded in?"

"The Sun-Slaying Meteor Crossbow, it has great killing power!" Senior Sister Red Butterfly leaned on the sofa, her black-stockinged legs under her JK skirt crossed, wearing a pair of flat shoes so red they were unsettling.

Although Senior Sister Red Butterfly's main image was that of a malevolent high school student, small details like her shoes and hair clips often changed.

"The rate of fire is too slow, not very practical." Xu Xiaomeng shook her head.

During monster attacks on the building, the Sun-Slaying Meteor Crossbow didn't get to fire many times.

"But it can attack before enemies even enter the dorm building. Just with this blood diamond's effect, it could definitely blow them to pieces!" Senior Sister Red Butterfly licked her bright red lips, excitement flashing in her eyes.

After becoming a Tenant of Dorm 200, freed from worries about her true consciousness awakening, Senior Sister Red Butterfly's nature was completely unleashed. She often proposed suggestions centered on "kill, kill, kill!"

"I think it could be used on the Micro Tri-Eye Machine Gun." Wang Yazhi walked out of the training room and joined the conversation.

The Micro Tri-Eye Machine Gun's attack speed was super fast. If it could get an area-of-effect damage on top of that, it would be practically invincible.

"The Void Splitter could work too." Cao Yaxuan spoke up.

"No." Xu Lang shook his head.

Cao Yaxuan immediately pouted. Why did he refute her suggestion but not anyone else's!

"The Void Splitter's effect of clearing out small fry is already sufficient. There's no need to add area damage to it." Xu Lang shook his head.

"What if it could mutate?" Cao Yaxuan argued stubbornly.

"What mutation?" Zhen Lu retorted.

Cao Yaxuan gestured as she explained, "Like, each projectile from the Void Splitter causes chain damage. So if there are lots of small monsters, and they're the same species as the big monster, maybe they'd just bounce to death!"

Everyone was astonished by Cao Yaxuan's idea.

If this concept really worked, the scene... they could hardly imagine it.

Xu Lang's heart stirred. He asked Li Wenwen, "Wenwen, once an Enchantment Gem is installed, can it be removed?"

"Uh... no, at least I can't do it now." Li Wenwen apologized.

"Alright then. Go ahead and create the socket first. We'll discuss installing the Enchantment Gem later." Xu Lang stretched lazily and walked towards the Nightmare Bed.

Simulation, activate!
