Demon Box World.
Reception hall.
Rainy Night Blade and Lone Wanderer had already left, leaving Xu Lang alone on the sofa, staring at a table full of rare items, lost in thought.
Besides the turret, there were various skill scrolls.
They fell into three main categories: eye techniques, blade skills, and cultivation methods. These were the unique items Rainy Night Blade and the others had helped him procure.
"Master, we've tested them. These foreign installations can't be installed. The dormitory building immediately flags them as contraband, there's no loophole to exploit."
At that moment, Mary and Tong Qi stepped out of the vortex gate.
Xu Lang's expression tightened slightly. Every dormitory building was highly vigilant about installations, much like customs strictly inspecting raw materials related to nuclear or high-tech weaponry.
Items and weapons could be mutually used.
Installations were the exception!
"Why is the Mad King Building like this? Those new tenants also brought installations, so why weren't they banned, but ours are?" Tong Qi complained a little.
Xu Lang shook his head and said:
"Heh, although Mad King Building lifted the experience requirement for recruitment, they actually enforce very strict checks. Before coming to Mad King Building, those people's backpacks were probably searched thoroughly."
"None of the new tenants brought installations that exceeded the allowed level. If a player really brought a level thirty high-rarity gate or a turret, then no matter how the next round's difficulty escalated, they'd still pass easily."
"Even a moderately mature operations department wouldn't allow that to happen, let alone a dormitory building."
Tong Qi nodded, finding it reasonable, then asked curiously, "Then why can our installations be so powerful?"
"Because we are already part of Mad King Building." Xu Lang could only think of that explanation.
The dormitory's control over players wasn't absolute.
"I see!" Tong Qi's brows relaxed. Hugging Xu Lang's arm, she looked up at him with bright eyes, "Lang Ge, you know so much. I would never have thought of these things!"
Xu Lang chuckled quietly and pinched her hard, making Tong Qi squeal softly.
She teased him deliberately because she sensed his mood was a little off.
Tong Qi had every quality of the perfect girlfriend; only her upbringing made her tastes less refined than wealthy girls like Cao Yaxuan or Zhen Lu.
But such manners were shaped by childhood environment; one couldn't demand more.
After some cuddling, Tong Qi and Xu Lang stared at the skill scrolls on the coffee table. Tong Qi asked, "Lang Ge, are you giving Zhen Lu and the others a special attribute?"
Cultivation methods came in two kinds: those that boost special attributes and those that increase the two base attributes. The latter were already held by everyone in Demon King Castle; the former still had vacancies.
"Yeah." Xu Lang nodded in agreement, then added, "Zhen Lu and the others don't need it at the moment. Sherry and I specifically asked for a special attribute related to spiritual energy."
Generally, special attributes didn't exist in isolation; they were tied to the two base attributes. They didn't require long training—just open a small gap.
For example, Blood Qi power, no matter how you train, only refines the control skill.
Only by increasing the two base attributes would the total amount of special attributes rise.
Seven Killings Blood Qi was already unique. It was the inherited blood qi of the A-301 Seven Killings Monarch. Killing others only purified its quality, it wouldn't increase the total amount.
Of course, there were exceptions. Ghostly Deity Power existed independently.
It was worth mentioning that as his horizons expanded, some of Xu Lang's confusions were dispelled.
For instance, why did the Sequence Encyclopedia list only fifty A-rank sequences, yet the Seven Killings Monarch was A-301?
Sequence arrays were divided into two parts.
Primal sequences and later-born sequences.
It was said that the primal sequences were all demoted from S-rank, existing together in a sequence sea, where source matter neither increased nor decreased.
This led to a terrifying conjecture: all sequences might have a true origin, including S-rank sequences!
Of course, this intelligence wasn't confirmed. It was just a theory Xu Lang and Sherry had discussed.
Primal sequences were interrelated. Once one changed, it could trigger chain reactions in esoterica. A-rank sequences were fixed at fifty, B-rank at one hundred, C-rank at two hundred, D-rank at three hundred, and E-rank at four hundred.
Xu Lang's fusion of two major sequences had stirred that entire sequence sea, and as time passed, the sea settled again.
Sequences at the tail end would be demoted.
Such fluctuations were rare and, whenever they occurred, the Gnome Emperor would mutter about them in the Sequence Encyclopedia.
From that one clue, Xu Lang already realized the disturbance his fused sequences had caused; otherwise he wouldn't be in such a hurry to plan in other dormitory buildings.
Growing stronger was, after all, the right move.
Besides primal sequences, there were also later-born sequences, which were power systems created by god-level figures imitating sequences.
Take the Seven Killings Monarch, for example.
These later-born sequences existed independently from the primal sequence sea. Their highest rank was only A, and their promotion path was very peculiar.
It was by killing peers who followed the same path!
Later-born sequences lacked uniqueness. One sequence could have many sequence holders!
When peers met, they had to kill each other!!!
This wasn't a hard rule, but it was as binding as iron. The selfish nature engraved in life could not be erased.
These secrets and observations were hard for ordinary players to learn.
Without Sherry's assistance, Xu Lang would have struggled to find the scattered clues in massive books to piece together his current understanding.
Tong Qi laughed, "Haha, Teacher Sherry is going to leave everyone behind in mental ability."
"Pretty much that's it." Xu Lang nodded, a trace of thought flashing in his eyes.
Spiritual energy was a popular special attribute because of its practicality. Once developed, it could manifest outwardly, granting telekinesis, mind control, and similar powers.
He had already gathered six cultivation method scrolls for spiritual energy; now Lone Wanderer had brought one more, making seven.
Fusing them all could very likely produce an advanced special attribute of spiritual energy.
Although Nightmare Essence was scarce now, taking out a few fusion chances to let Sherry fuse one cultivation method book was still doable.
"Lang Ge, what are you thinking? Even if you don't upgrade to an advanced special attribute, Teacher Sherry won't blame you." Tong Qi misunderstood and said softly.
"I'm not thinking about that." Xu Lang shook his head and smiled.
Tong Qi saw that Xu Lang didn't press the matter and didn't ask further. This was the tacit understanding between tenant and dorm owner.
Xu Lang was thinking whether to increase his strength.
His own power hadn't qualitatively changed for a long time, and it made him a bit itchy.
Having over half a million Nightmare Coins just sitting there gathering dust—was that really right?
Obviously extremely wealthy, yet living like an ascetic.
