"You have repelled the Eternal Nightmare, Nocturne, gaining 5 levels, 20 skill points, 3000 blue essences, and 1500 orange essences."
"Congratulations! Your level has increased to 44, gaining 5 skill points."
"Health: 9480/9480"
"Mana: 7145/7145"
"Combat Power: 55"
"Skill Points: 53"
"Wealth: 3258 blue essences, 3782 orange essences"
With these prompts from the system in his mind, Li Lin breathed a sigh of relief.
Nocturne was tougher than he had imagined. Even after speaking his true name, it was still somewhat difficult to kill him without some real skill.
After all, being the embodiment of human negative emotions, Nocturne was different from the individual parasites like Azakana.
It couldn't be killed like a regular Azakana; it could only be forcibly sealed or dispersed, only to revive later.
But even so, Li Lin was quite satisfied.
The rich rewards this time were just as he had expected, directly jumping to level 44, with generous skill points and essence rewards.
Upon reaching level 40, the skill tree of the inventor branch unlocked rocket launchers and artificial satellite technology, which delighted Li Lin.
With satellite technology, communication range could be greatly increased, and it had multiple functions such as resource exploration, tracking, and navigation.
If combined with the runes, no matter who Li Lin wanted to find, they would have nowhere to hide as long as they were in this world.
After making a few more inventions that had not yet been made, reaching level 45 would unlock a technology called "Particle Control" in the inventor branch.
This was related to the application of a new type of electromagnetic energy weapon in the combat system, with the plasma cannon being one of them.
It could replace the existing electric shock cannons that only applied energy at a basic level, greatly increasing power.
Moreover, with particle control technology, Li Lin could also create plasma thrusters, eliminating the need for further brainstorming for the flight module of the Infinite Armor.
The Flight Mech Storm and the Resource Storage Support Flight Device Dawnlight could also be upgraded with improvements.
However, this was not the place to allocate skill points or learn new technologies.
Li Lin returned to his original position, retracting the crystal-enhanced spire, taking a deep breath, and preparing himself.
Then, he activated the "Domain Translocator" armor worn on the outside of the battle armor, connecting the anchor points installed in the material domain.
In an instant, his figure was once again covered by a dazzling bright white light.
As the energy white light gradually dissipated, Li Lin disappeared along with it.
...
...
Material domain, laboratory next to Heimerdinger's office.
Heimerdinger, Viktor, and Skye were staring at a peculiar device, somewhat similar to the "Hextech Detector" Li Lin had previously purchased from the Essence Shop.
It could be used to detect the hex energy index in the spiritual realm, and it was a work of Heimerdinger's youth when he was studying.
Now, after some improvements, it has been applied to professional fields.
"Professor, the energy fluctuations in the spiritual realm have subsided..."
"Has the battle ended? Is Li Lin okay?" Taking over Viktor's words, Caitlyn, who was standing guard next to Valentina, who was lying on the bench asleep, asked eagerly.
"Don't worry, child. Energy fluctuations in the spiritual realm are quite normal. Maybe the nightmare won't come tonight?" With that, Heimerdinger asked Viktor to hand the detector to himself, looking at the peak records on the dial, raising his eyebrows, and gently stroking his beard.
After a few seconds of pause, he whispered in surprise, "Oh ho ho~~ The energy peak fluctuations have exceeded the limit! It seems that Li Lin has had a confrontation with the nightmare."
"He should be back soon." Viktor glanced at Caitlyn, as well as Skye, who was guarding Valentina beside her, and added softly.
"Miss Kiramman, you don't need to worry too much. Look at Professor Zidelo."
Skye pointed to Valentina's sleeping face. Originally, her brows were tightly knit together, looking like she had a nightmare.
Now her eyebrows were relaxed, and her expression was much calmer.
But this was only a slight consolation and couldn't ease Caitlyn's nervousness and anxiety.
She shook her head, pursed her pink lips, and said nothing.
Except for the sound of breathing and the buzzing of energy supply, the room fell silent again.
Not long after, Caitlyn felt the metallic acidity in her mouth increase slightly, and she quickly looked towards the base of the "Domain Translocator".
Only to see white energy gathering on the base, she quickly stood up, half covering her face with her hand to avoid the strong light from hurting her eyes.
In less than three breaths, the intense light faded, and a familiar figure in powered armor appeared in everyone's sight.
"Li Lin!" Caitlyn's eyes reddened as she ran to him, throwing herself into his arms.
Still recovering from the teleportation, Li Lin was momentarily stunned.
It wasn't until Heimerdinger, Viktor, and Skye also approached that he managed to calm his discomfort and regain his composure.
"Caitlyn..."
Feeling her embrace, Li Lin opened his helmet and armor, wrapping one arm around her shoulder and the other around her slender waist, gently kissing her forehead.
After a while, Li Lin and Caitlyn separated, and he wiped a tear from her eye, comforting her, "Look at you, I'm not injured. Shouldn't you be happy?"
Caitlyn pouted and snorted lightly at Li Lin, "It's all because of you... Do you think I'd be this worried if it were someone else?"
She noticed the smile on Li Lin's face and realized what he was about to say next, so she quickly added before he could speak, "Except for my parents."
"Don't mind me interrupting your moment, children, but I'd like to ask, what's the situation?" Seeing the two of them lingering affectionately, Heimerdinger blew on his beard and couldn't help but ask.
"Judging by your appearance, it should be resolved." Viktor smiled and shook his head.
Holding Caitlyn's hand, Li Lin glanced over the others, first focusing on Valentina in the distance.
Then, he withdrew his gaze, scanning Viktor and Skye before finally lowering his head to look at Heimerdinger.
"I've vanquished Nocturne," Li Lin said, "but it's the embodiment of human emotions. I couldn't completely destroy it."
Skye's face showed concern. "So... that guy will eventually come back for Professor Zidelo, right?"
"I'm not sure how long it will take for it to revive, but it shouldn't target Professor Zidelo again." Li Lin paused, speaking with seriousness, "Professor Heimerdinger, you should know that there are still many demons in this world, right?"
Heimerdinger pondered for a moment. "They are the embodiments of sentient emotions, especially the Ten Primordial Demons... Revealing their true names only works for other demons, but for the incarnation of ancient fear, doing so will only summon it."
He proceeded to educate Caitlyn, mainly Viktor and Skye, about some new knowledge.
"We should develop a device that can seal demons, preventing them from causing havoc." Viktor guessed Li Lin's thoughts and immediately suggested.
"But... I don't think it's realistic," Heimerdinger shook his head, "The birth of a nightmare is only a few thousand years, but even so, a group of mages can only barely seal it in the spiritual realm. Magic is still like this, and technology is even less possible."
Li Lin smiled. "But I think we can turn the impossible into possible."
Before Heimerdinger could respond, Li Lin went to the workbench on his own, picked up a pen and a piece of paper, and quickly drew and wrote on it.
Caitlyn, Heimerdinger, Viktor, and Skye all approached at the same time.
Heimerdinger brought over a stool and stood on it, seeing what he was drawing on the blueprint, "Child, what are you doing?"
Li Lin didn't reply.
After more than ten minutes, two blueprints that were still very standard and accurate without a ruler were completed.
"This drawing is the intelligent chip concept I proposed to you more than half a year ago, and I have researched and developed it."
"Hmm?!"
Heimerdinger widened his eyes and quickly "snatched" the blueprint from Li Lin, looking at it carefully for tens of seconds.
"Wonderful~~ wonderful! So, that's where my problem lies..." He looked up, his eyes met Li Lin's with astonishment, "Child, how did you research and design it?"
"That's another matter."
Li Lin handed him the second blueprint.
"I designed a device based on the concept of 'AI' you previously proposed, and through it, I developed the intelligent chip."
Li Lin smiled slightly, "But I prefer to call it a computer, or perhaps a PC."
