Inside the Sky Dome train's science module, the Infinite crew gathered together, quietly listening to Lin Xian recount the two civilization simulations he had just witnessed. Each person wore different expressions, their eyes fixed on Lin Xian.

"Sounds like some kind of AI-calculated game," said KIKI, who had rushed over still wearing shorts and pajamas, floating in the air with crossed arms and furrowed brows. "The key question is, what does it represent?"

"Could it be trying to tell us that human civilization is ultimately doomed to destruction?" Ning Jing scanned the group as she spoke.

"Absolutely impossible," Fire Bro declared with confidence, his voice coming from where he stood alone in the corner.

"Heh," Qian Dele sighed softly while fanning himself with a small fan. "So they're using this method to undermine our confidence? Is the Foundation that bored or is the dark civilization that bored?"

Chen Sixuan leaned against the table, deep in thought. "Lin Xian has now experienced two civilization simulation games, but both ended with human extinction. Hua Xiaoling told Lin Xian that through this game he would gain a completely new understanding of the dark civilization and the Star Abyss. I'm wondering if there's some hidden information within this."

"Definitely," Luo Yang nodded with serious expression. "Didn't Brother Lin just say that the holographic experience this thing provides feels completely from another dimension? That means this isn't human technology but from another civilization. There must be more information hidden within."

"Well that's simple enough," Shasha chimed in. "Brother Lin is a mechanical ability user, just scan it directly."

Lin Xian shook his head at this, weighing the silver metal sphere in his hand. "This thing is covered by a force similar to Forbidden Artifacts. I can't scan it, and I can't disassemble it either."

Monica spoke up from the back of the crowd. "Why does it jump from Civilization 1 directly to 807? Did we miss something in between? Or were all the civilizations in between simulation failures with no reference value?"

"Like what?"

"Like the dinosaur age," Monica shrugged.

"Dinosaurs... are they related to this?" Lü Chang asked with a puzzled expression.

"She means the butterfly effect that influences civilization development," Ding Junyi explained, having put down her work and turned around with hands in her pockets. "From the Triassic period to human evolution, spanning tens of millions of years—a single meteor crisis, a century-long rainstorm, an ice age, or even extremely minor changes in the universe could cause human civilization to disappear, wiped out before it could sprout. Strictly speaking, a civilization requires the combination of numerous favorable conditions of timing, geographical advantages, and human unity to emerge." She looked toward Viola as she continued, "If an AI were to perform calculations, even with identical initial conditions, too many variables would cause possibilities to diverge exponentially. So selecting valid references for demonstration should be reasonable."

[I agree with this conclusion,] Viola's calm voice sounded as she addressed Lin Xian. [This civilization simulation calculated humanity's development 700 years into the future. Preliminary calculations show its computational power growth multiplier exceeds 10^6700, and this conclusion doesn't account for nonlinear complexity growth so it's not accurate.]

"Then we've reached a conclusion," Lin Xian placed the silver metal sphere on the experimental table, and everyone's gaze simultaneously fell upon it. "This thing indeed comes from an extraterrestrial civilization. Since Hua Xiaoling gave it to us, it likely represents the dark civilization."

The atmosphere suddenly grew tense at these words.

Chen Sixuan broke the silence with a complex expression. "If the dark civilization indeed possesses extremely high intelligence, then our operations in Dawn City..."

"Let's not jump to conclusions," Lin Xian interrupted her. "Chu Yan and I clearly connected with the consciousness of dark creatures. Plus, including the Phoenix Society, we've had such judgments before. Such high intelligence and technological advancement are based on our understanding. Let's not imagine the dark civilization as omnipotent yet."

Qian Dele shrugged. "If they were that powerful, they would have sent Sanctum and Sacred Revelation people to assassinate him already. I think once the tide comes in, everything becomes unknown."

"Right," KIKI looked at Shu Qin, then gestured toward the metal sphere on the table with her chin. "Since there's no danger and it can enhance your ability, you should try it a few more times. Maybe the problem is actually very simple—better than all of us guessing blindly here."

Lin Xian nodded. "I was thinking the same thing."

"Since the Foundation has their eyes on us, should we depart immediately after daybreak?" Ding Junyi asked cautiously.

"No rush," Lin Xian looked at the metal sphere on the table, his eyes flickering. "This isn't our first time dealing with the Foundation. Hua Xiaoling must want to convey some information through me and the Phoenix Society. Otherwise, if they wanted to take direct action, the fight would have already started."

He scanned the group as he shared his thoughts. "Rest opportunities are rare. We're not being chased by the Star Abyss Polar Night right now, and we don't have dark marks either. South America will definitely bring constant troubles. The massive relocation from Dawn Center is being hunted by various Star Abysses. Since we'll ultimately need to flee to the poles anyway, why don't we rest properly here? Our equipment, Forbidden Artifacts, and so on all need improvement and adaptation."

Hearing this, Shasha immediately nodded her head like she was knocking on a wooden fish, her eyes shining. "I agree! I agree! My Flying Peach hasn't finished its modifications yet! Plus there are still many areas on this island we haven't scavenged. Since our big spacecraft can carry everything, let's not waste anything!"

Ning Jing and Shu Qin also nodded. "Indeed, such intense places might become rare soon."

Qian Dele smiled and leaned forward. "I don't care anyway. Hawaii's sunshine is quite comfortable—might not get to enjoy it later~"

Hearing this, Lu Xingchen also nodded. "Hey, this place is indeed suitable for cultivation."

"Just too many zombies, all that groaning and moaning~" KIKI shrugged.

"Okay, then if that's the case, tomorrow we'll continue splitting into multiple teams to thoroughly search this island, treating it as rest and recuperation," Chen Sixuan said with some relief.

"Agreed," Lin Xian said calmly. "Many areas on the island now have signal coverage. Maintain communication and you can move freely, though it's best not to travel alone."

"Lin Xian," KIKI addressed him. "Since we have this opportunity now, do you think we should attempt Crystal Lattice evolution? We've obtained quite a few level 4 blood crystals and could use this chance to enhance everyone's strength. What do you think?"

At these words, everyone became interested. Monica looked at Lin Xian with a glowing smile.

Lu Xingchen's eyes also lit up as he put down his hands excitedly. "Brother Lin, this cultivation method—I am willing to risk trying it!"

"No need for risks," Lin Xian said. "According to Phoenix Society data, using level 4 blood crystals at spirit values above 10,000 almost never causes accidents. Plus, if performed under the dark energy resonance device, it can reduce physical damage. The only remaining issue is the possible side effects. One thing that's currently certain..."

He scanned the group and spoke solemnly: "Reduced lifespan."

The moment these words fell, everyone's eyes flickered, but no one appeared nervous. Qian Dele actually burst out laughing. "I thought it was something serious! Lifespan? Every day we live is profit! Who cares about that during the apocalypse!"

"How much lifespan reduction?" Ning Jing asked.

Lin Xian shook his head. "Uncertain. The Phoenix Society reached this conclusion from cell division analysis. Currently, it appears to reduce a person's lifespan by at least 5 to 10 years, possibly more."

After hearing this, Ning Jing immediately said, "10 years? What does that matter? If I can double my combat power, even 20 years wouldn't matter."

"I feel the same," Shu Qin added.

Lin Xian smiled wryly. "My thoughts align with yours. If it's just lifespan, it's not a major issue. As for other side effects, we'll take it step by step."

Then he looked directly at Ding Junyi. "Last night I had Viola prepare a plan. Considering full team safety, everyone will be divided into three batches for Crystal Lattice cultivation. We'll use hibernation pods and cryogenic systems as Crystal Lattice incubation chambers, with me providing final security. However, we lack experience in this area. Cai En and Vanessa told me Crystal Lattice cultivation requires at least 72 hours. To be safe, I've discussed with Monica—she'll conduct an experiment first. After she succeeds, we'll proceed with batch processing."

"Monica?"

Several people turned to look at him simultaneously. Fire Bro, who had been eager to volunteer, swallowed his words. Though his personality naturally attracted him greatly to anything that could enhance his "cultivation," he always supported Lin Xian's decisions, so he suppressed his excitement.

Monica nodded and smiled at the group. "Don't worry, I'll experience it first for everyone. If I gain any insights, I'll share them after I wake up."

"Your current spirit value peak hasn't reached 10,000 yet, right?" Qian Dele asked.

Monica raised her hand, releasing a substantial-looking sound wave in her palm. "It's alright. After that night, it reached 8,500. That's the limit index, barely acceptable."

Crystal Lattice matters couldn't be rushed. They had time now and could use this opportunity to thoroughly research it.

"Then it's decided," Lin Xian said.

He also knew that if this group's ability indices could all double, then even without the Sky Dome train, many of them could face special-level entities head-on, and perhaps even put up a fight against S-level threats.

After this, everyone visibly relaxed. Such rest time was quite rare—no urgent travel, abundant island resources. Everyone could properly unwind from the tense crises of the Oceanic Titan and volcanic eruption.

Ding Junyi looked at Lin Xian and advised, "The hibernation pod's sedation life support system can indeed effectively maintain mental stability, but it has drawbacks. If subjected to mental attacks, there will be no resistance whatsoever. Even with dark energy resonance shielding against dark infestation, complete protection isn't guaranteed."

"I know," Lin Xian raised his hand, and a Heterogeneous Cube landed in his palm. Then he looked at Monica. "That's why I prepared double insurance."

Qian Dele smiled and leaned forward. "I don't mind anyway. Hawaii's sunshine is quite comfortable—might not get to enjoy it later~"

Monica looked at Lin Xian with a faint smile. "I'm genuinely touched. You're so good to me."

Lin Xian said helplessly, "No choice. Since you volunteered yourself, as team leader, I naturally need to protect you."

Monica's lips curled slightly as she glanced at Lin Xian, saying nothing.

Afterward, everyone proceeded to Sky Dome Two, which housed the low-temperature hibernation pods and civilization embryo chamber, while also serving as the functional hull for orbital guidance, star navigation systems, and gravity field systems.

Monica had now removed her power armor and stood wearing a form-fitting white undersuit beside a low-temperature hibernation pod that Lin Xian had opened.

"What do I do?"

"Lie down inside," Lin Xian said with a grave expression. Everyone watched as he now produced the Crystal Lattice cultivation device given by Vanessa. It resembled an X-shaped metal breastplate with a central slot. Lin Xian placed a level 4 blood crystal into it, then activated the device. With a humming sound, dark red energy began flowing through pipes beside the slot, and the entire device erupted with intense dark energy fluctuations.

At this moment, Lin Xian activated the dark energy resonance device installed in the chamber while simultaneously installing the Heterogeneous Cube. Instantly, the space's dark infestation and chilling sensation were swept away, replaced by a clear, cool feeling.

Lin Xian approached the hibernation pod. Under everyone's watchful eyes, Monica stepped into the pod and slowly lay down. Then he gently fastened the device onto Monica's chest.

"If I become really ugly during the evolution process, just cremate me directly," Monica met Lin Xian's gaze with a confident smile. "Rather than becoming a monster, I'd prefer to die beautifully."

"Ah? Will you become ugly?" Shasha couldn't help asking upon hearing this.

"Vanessa mentioned before that such cases have occurred, like certain mutations of monstrous limb abilities," Shu Qin said.

Lin Xian looked quite seriously at Monica. "What if your beauty remains but your body changes? Like growing hair all over, or developing a third breast..."

Pfft...

Lin Xian's words immediately dissolved the tense atmosphere. KIKI burst out laughing, Chen Sixuan gave him a helpless glare, and Monica in the hibernation pod coldly turned her gaze away with a frosty response.

"Burn it."

"Understood, Queen Mo," Lin Xian smiled slightly, then pressed the activation button on the Crystal Lattice cultivation device. Instantly, the device hummed, and a crimson flood surged across Monica's skin surface like a spiderweb, spreading from her neck all the way to her face, appearing like some terrifying energy pattern.

Monica's expression suddenly changed, gritting her teeth with a muffled groan as immense pain assaulted her. The next moment, her pupils were completely covered by a glowing white, her arm went limp, and her consciousness sank into sleep.

"What happened?!" Chen Sixuan asked nervously.

"It's working," Lin Xian looked at the hibernation pod's life detection system. After a strange ECG fluctuation, Monica's vital signs began stabilizing. Everyone watched breathlessly, only relaxing after several minutes of stability.

"Looks quite dangerous still. Who knows what she'll experience during these 72 hours," Ning Jing frowned. Even for these battle-hardened ability users, such active evolution inevitably brought some tension.

Lin Xian now closed the hibernation pod and arranged for service drones to begin monitoring.

"Viola, closely observe Monica's condition. Report any abnormalities to me."

[Viola understands.]

Lin Xian breathed a sigh of relief and dismissed everyone to rest. Soon, all had departed one after another.

After hearing this, Ning Jing immediately said, "10 years? What does that matter? If I can double my combat power, even 20 years would be nothing to me."

Lin Xian nodded. "I hope so."

Then he left the hibernation chamber with Chen Sixuan. Only after returning to the main bridge did Lin Xian turn his attention to himself. He examined his Mechanical Heart—a whole night of Devour couldn't compare to the dark energy conversion captured from those two simulations. Though unclear what exactly the metal sphere in his hand produced, it had certainly given Lin Xian a windfall. Originally estimating he'd need another day to reach LV.7, he had unexpectedly achieved it before dawn.

[Current Mechanical Heart Level LV.7 (2180/100000)]

[Mechanical Awakening]: Mechanical Lord

Mechanical Devour: 6 (3600/5000) Increases devour efficiency

Mechanical Manufacturing: 6 (1560/5000) Increases construction efficiency

"Power Resonance..."

Lin Xian looked at the Mechanical Heart's skill description, not entirely understanding what this skill meant. Resonating mechanical power to him—wasn't this similar to how his hyperstring reactor phase halos drew power from the Infinite?

Lin Xian clenched his fist, attempting to activate this skill. Suddenly, the Sky Dome train's 5000-megawatt [Star Drive] class nuclear power core erupted with terrifying might, all concentrating into his fist. In that instant, Lin Xian experienced an incredibly bizarre illusion—he felt like he had returned to piloting the prototype unit with Chen Wei! Throwing a punch now felt like swinging the prototype unit's mechanical arm with over two thousand muscle engines roaring, driving hydraulic power actuators to explosively release tremendous force measured in thousands of tons!

But unlike before, this power originated from the Sky Dome train!

"Whoa, so this is how Power Resonance works?" Lin Xian's eyes widened in shock.

"Isn't this Mechanical Soul Armament, mech embodiment???"
