Ignoring Gu Shenghui's question, Pei Yan continued to listen to the change in the voice in his mind until a gentle and pleasant voice appeared. Only then did he subconsciously nod in satisfaction and murmur inwardly, "It's her, from today on, you shall be called....? Hmm?" Pei Yan pondered for a moment and then blurted out, "Suzi!"

The newly-named Suzi responded in his mind, "Kusanagi Motoko from Ghost in the Shell?"

"You even know that?" Pei Yan was surprised for a moment, but then understood and answered himself, "I forgot you share memories with me. Enough small talk. How long will it take to解除身体现在的状态?" With that, he tried hard to clench his swollen hand, and the sensation of muscle-exploding pain hit him again.

"You need at least twelve hours of rest to fully digest this sudden surge of power in your body. To alleviate the soreness and have your body fully recover, it will take at least forty-eight hours," Suzi answered after hearing the question.

Understanding this, Pei Yan turned his head to Gu Shenghui and said, "After I absorb the last batch of equipment, I will need two days of rest. I believe during this time, Director Mei should also be waking up. Additionally, I hope the investigation department can arrange for me an equally matched opponent; I need to enhance my strength before the confrontation."

"An equally matched opponent? How about Xia Yu?" Gu Shenghui asked as he supported Pei Yan toward the remaining equipment.

"Xia Yu is strong. I'm sure she will get even stronger, but not right now! I need someone stronger!"

Looking at Pei Yan with battle readiness in his eyes, Gu Shenghui said coldly, "You've already decided who you want, right? Tell me his name!"

"Zheng Jia Ru!"

Hearing this name, Gu Shenghui was stunned for a second and then said, "I thought you would choose Jiumu's brother, Ye Ruozai. How did you end up choosing him?"

Pei Yan shook his head with a wry smile and said, "Ye Ruozai might be very powerful, and I would also like the chance to fight him again, but he doesn't fit my current situation. I've observed Zheng Jia Ru's battles. Facing him would improve my combat abilities more."

Gu Shenghui nodded in agreement after a short silence, "That's a wise choice. Okay, I'll arrange it for you. Do you have any other plans you'd like to tell us about?"

"Just wait! There's no use saying it now; the time isn't right yet!" While speaking, Pei Yan had already arrived in front of the new equipment. Just as he was about to reach out and touch it, Engineer Li stopped his wrist with his hand and said, "Pei Yan, are you sure you want to absorb these things? And such a large amount! These devices were produced long ago but have never been put into practice. Aside from technical issues, their lack of effectiveness in combat is a major concern. I don't think these weapons will do you any good. Don't be fooled by online data. Are you sure you want to absorb them?"

"Thank you, Engineer Li, but I really want to absorb them. I have my reasons," Pei Yan replied with a smile in the face of Engineer Li's goodwill.

Seeing his persuasion was ineffective, Engineer Li stepped back two steps, spread his hands, and agreed, "Fine, since you're so determined, I won't stop you."

Watching Pei Yan stand beside a large pile of instruments slowly absorbing them, Gu Shenghui pulled Engineer Li aside and whispered, "Engineer Li, what are these pieces of equipment?"

Engineer Li glanced back at Pei Yan and sighed, "Infrasound weapons!"

Gu Shenghui asked in confusion, "Infrasound weapons?"

"Yes, infrasound weapons, capable of emitting infrasound waves that can't be heard by human ears to cause resonance, which interferes with the normal functioning of the nervous system, posing a threat to human health. Certain strength of infrasound can cause dizziness, nausea, vomiting, loss of balance, and even depression. In severe cases, it can cause organs to deform, displace, or even rupture, thereby achieving destructive purposes," Engineer Li patiently explained.

"Well, that's... that's powerful!" Gu Shenghui changed his expression after hearing this; it could kill silently without a trace.

"But this kind of weapon is very immature. Regardless of the output power and volume ratio, distance during combat, or the harsh requirements of complex battlefield environments, they only allow this weapon to continue to be explored in practice. Although it has undergone many trials on the battlefield, it is far from ready for service," Engineer Li said with a face of regret.

Hearing this, Gu Shenghui squinted his eyes and looked at Pei Yan, muttering, "But since he insists on absorbing these devices, he must have his reasons. What exactly did his sister tell him? What energy did he gain from that mysterious crystal? I'm really getting curious now."

Four hours passed, and it was midnight when Pei Yan, after absorbing all the equipment, slumped to the ground. Gu Shenghui and others quickly went forward to support him and carried him back to the dormitory.

In a state of unconsciousness, Pei Yan did not know how long he had slept. When he awoke, he looked at the dimly lit room, glanced at the clock by the bed showing nine-thirty, and rubbed his extremely sore shoulders. As Suzi said, after resting, the previous swelling and pain had vanished, and his limbs could move flexibly.

Jumping out of bed, he strode to the window and pulled open the curtains. The dazzling sunlight hit his eyes, and he instinctively used his hand to block the light, only to smell an acidic, bloody odor on himself. Looking down, although his clothes were stripped clean, leaving only his underwear, the blood stains on him mixed with sweat stench made him frown.

At this moment, hearing the commotion, Wang Wenze pushed open the door and peeked in, smiling, "You're awake? How do you feel?"

"My body is still a bit sore and stiff, and I'm very hungry! How long have I been asleep?" Pei Yan asked back.

"From when you collapsed until now, it's been a full day and night. Want to eat first? I can notify Gu Chu?"

"No, let me eat something first and then take a bath; we can notify him afterward."

An hour and a half later, after devouring a meal, Pei Yan lay comfortably in a big bathtub, the scorching water washing off all the blood stains, relaxing and easing his muscle soreness.

While flushing his body with water, Pei Yan looked at his skin. He didn't know if it was a blessing in disguise, but after being cleansed by this energy, his once dark skin had become fair and tender like a baby's.

But he didn't focus on that for long. In the steamy bathroom, he recalled his sister's messages and the instructions from the Origin Maiden, thinking about his next steps. Setting aside the Origin Maiden, his sister had secretly protected him for twelve years, bearing the burden while he unknowingly enjoyed life. Now it was time for him to take up that responsibility.

One hour later, after cleaning up and changing into new clothes, Pei Yan appeared in front of Gu Shenghui with renewed vigor, sweeping away all previous dissipated air.
