Dorm 200.

Xu Ruyan, Xu Xiaomeng, Wu Huihui, and Luo Lin with her daughter had all arrived.

Yes, upon learning that Xu Lang wanted to meet Luo Lin and her daughter, Xu Ruyan immediately brought Xu Xiaomeng along.

Would her tenant spot be snatched away?

When she saw Luo Lin's cool and elegant appearance, this sense of crisis grew even stronger.

This was Wu Huihui's first time entering Dorm 200, and her initial impression was one of luxury and refinement—the room was spotless, as if someone cleaned it daily.

She glanced around nervously, but Xu Lang seemed completely uninterested in her, his gaze entirely focused on Luo Lin.

"Do you know Professor Helenburg?" Xu Lang got straight to the point, asking directly.

A startling brilliance instantly flashed in Luo Lin's eyes as she exclaimed with great surprise, "You know him?"

Xu Lang nodded: "I saw it in item information. Golden Revolution was developed by him, right?"

"Yes, yes!" Luo Lin nodded repeatedly at first, then said in astonishment: "Item information? You mean you're not from Star City?"

The shift from fellow townsfolk to stranger was quite a significant gap.

"No." Xu Lang shook his head, his shining eyes fixed on Luo Lin: "Let me ask you something—can you still manufacture Golden Revolution now? Even lower-level Evolution Serums or Ability Potions would work!"

Hearing this, Luo Lin fell silent. 𝒻𝘳𝘦𝘦𝘸ℯ𝒷𝘯𝘰𝑣ℯ𝑙.𝘤𝑜𝘮

This man before her seemed to know a lot of information.

After weighing her words carefully, she replied: "I'm sorry, but probably not. Evolution factors are extracted from zombie gene samples, and it seems you don't have zombies here."

Xu Lang's eyes flashed.

Evolution factors are extracted from zombie genes?

So zombies came first, then evolution serums!

"The national research institute you mentioned serves warfare purposes, right!?" Xu Lang made a shocking statement.

Luo Lin's expression changed drastically, and she instinctively moved to protect her daughter.

"Don't lie, I can hear your heartbeat." Xu Lang raised his index finger and shook it.

Everyone looked at Luo Lin in surprise.

So Luo Lin's background wasn't that of a national researcher—she was more likely an evil scientist serving a terrorist organization!

Luo Lin took a deep breath and responded: "Yes, you're correct."

Xu Lang was alarmingly perceptive, making her feel like she was facing an enemy spy—she wished she could sew her mouth shut!

"I'm not interested in your past, I just want to tell you not to lie in front of me." Xu Lang gave Luo Lin a deep look.

This woman was definitely not simple.

Hearing Xu Lang's words, Cao Yaxuan felt somewhat awkward.

Because she often tricked Xu Lang, saying things like her body was tired, she didn't want to earn points, didn't want to cook, wanted to lie down a bit longer, and so on.

Had Xu Lang seen through all of these?

"Yes, I understand." Luo Lin had sweat beading at her temples.

She secretly resolved to meet with Xu Lang less frequently in the future.

"I have a zombie here. See if you can extract evolution factors from it, and how long it would take." Xu Lang took out the Zombie Summoning Card.

This Zombie Summoning Card was familiar to Cao Yaxuan and the others, but Wu Huihui had never seen it before and kept staring at it.

Under Luo Lin's astonished gaze, Xu Lang shook the card, and a zombie materialized out of thin air!

"Mommy, it's a zombie!" Tao Tao said fearfully.

These were her first words since coming to Dorm 200.

Luo Lin patted Tao Tao's head, and seeing that the zombie showed no intention to attack, she stepped forward to examine it. After a moment, she said: "This is just the lowest-level zombie. Manufacturing an Evolution Serum from it would be very difficult."

Xu Ruyan spoke up at this point: "Xu Lang, when the time comes, the zombie will disappear. Cells and such probably won't remain either."

"This problem should have a solution."

A short while later, Xu Lang purchased an item from the Trading Network.

[Centrifuge Tube]

[Type: Item]

[Level: 1]

[Effect: Can preserve biological samples]

[Upgrade Condition: 20 Nightmare Coins]

[Introduction: Basic research equipment produced in biology classrooms]

Xu Lang tore off a small piece of flesh from the zombie and stuffed it into the tube, then activated the summoning card to recall the zombie.

The zombie transformed into faint light and dissipated, but the flesh in the tube remained, its name changing to "Centrifuge Tube Containing Biological Flesh."

"Xu Lang, you're really good at this." Cao Yaxuan gave a thumbs up.

"Basic operation." Xu Lang smiled.

This was just reasonable application of item mechanics—nothing particularly ingenious.

"You have other cards like this, right?" Luo Lin, being clever, asked.

Xu Lang nodded: "Mhm, what level of zombie do you need to research and develop an Evolution Serum?"

Luo Lin opened her mouth, thinking of Xu Lang's "don't lie" warning, and honestly said: "At least one high-level zombie."

"High-level zombie?" Xu Lang asked in return.

Luo Lin began to describe.

High-level zombies referred to the three bosses from the first round of the game, like the Cat Demon and Large Zombie.

"If I had a basic laboratory, making one Evolution Serum would take about a day, since it's just me—no assembly line operation... As for manufacturing Golden Revolution, I'd need at least a tyrant-level zombie's gene sample."

Xu Lang nodded to show he understood, then didn't elaborate further on the topic. Instead, he stretched his hand out toward Luo Lin: "Give me the thing."

Luo Lin pressed her lips tightly together and remained silent.

"This is the key to Dorm 186. It's a level 2 dormitory equipped with a level 3 door and a level 4 turret. It used to be my dorm." Wu Huihui took out a silver key and handed it to Luo Lin.

"What about you?"

"I'm living in Sister Yan's Dorm 180 now."

Xu Ruyan wasn't some slacker player—before coming to the Mad King Dormitory Building, she had placed in the top ten three times, and got another top ten in Fierce Ghosts Return. Her dorm was level 4, and with Wu Huihui moving in, she really wasn't inferior to other veteran player dorm heads anymore.

This was something Xu Lang tacitly approved, since Wu Huihui had been doing quite well as a dorm head.

Moreover, location 186 was very safe!

If Luo Lin could truly reproduce Evolution Serums, she would be an absolutely incredible money-printing machine with immeasurable value.

Hearing this, Luo Lin took the key: "Thank you!"

"Don't thank me yet. Huihui's dorm is more valuable than Golden Revolution. You'll have to work for me to pay off the debt in the future." Xu Lang stared at Luo Lin calmly and said: "Of course, I'll also provide you with research facilities."

Paradoxically, Xu Lang's words made Luo Lin feel completely at ease.

"Okay!"

"You can leave now. Oh, and Wu Huihui, thank you for bringing Luo Lin here." Xu Lang looked at Wu Huihui and said with a smile.

"Ah, it was nothing!" Wu Huihui waved her hand, then said sheepishly: "Lang Ge, do you still have any Frost Sets? I'd like to advance two sets and pay you back when I have the money."

It was still early in the game, the perfect time to compete for resources. If Dorm 180's strength increased collectively, they could be more domineering too.

"Okay." Xu Lang smiled and nodded.

After Wu Huihui and the others left, Xu Lang gave the two tenant spots to Xu Ruyan and Xu Xiaomeng and told them to go take showers.

The night had grown very deep.
