Although the resources used were from the hall, the two people who helped Pei Yan the most when he first entered the supernatural realm were Instructor Hu and Engineer Li. Engineer Li also held special feelings for Pei Yan. To say they were like father and son would be an exaggeration, but in Engineer Li’s eyes, Pei Yan was the most outstanding work he was involved in creating and a trustworthy junior. There’s no doubt about this, so he is extremely happy for the achievements Pei Yan can obtain.

"Oh my, not only have your powers grown, your height has too!" Engineer Li measured the distance between the two. Since Pei Yan started traveling back and forth between the Hell Plane and Daoist Realm, they had only had a few hurried encounters. For Pei Yan, nearly six years had passed, but Engineer Li had only experienced a few months in reality.

"If calculated by time, I’m almost 25 now. It seems I’ve spent my final years of youth in the alternate dimension." Pei Yan touched his head and smiled bitterly.

"Hmm, it seems you all have sacrificed a lot." Engineer Li nodded appreciatively, "After Gu Chu notified me, I arrived immediately. The equipment you need is all stored in my storage ring. I dare not take it out now; you know how the alternate dimension repels and affects scientific instruments from the base dimension. Therefore, I’ll only take them out when it’s time for your examination, and you can cover them with your powers to ensure they function."

Saying this, Engineer Li rubbed his hands together, eagerly and excitedly asking, "I heard from Gu Chu that experts from other dimensions have been sent to transform you. Where are they? Can we start now? Can we observe and learn from the sidelines?"

Engineer Li’s eyes shone with excitement, leaving Pei Yan a bit helpless. He knew Engineer Li had a huge interest in this area, so he didn’t keep it a secret and candidly replied, "Everyone is gathered, just waiting for you. If you’re not tired and don’t need a break, we can start now."

"Not tired! Not tired! Let’s start now."

At Engineer Li’s urgent insistence, Pei Yan led the personnel from the investigation department into the sundial set up by Lin Ruxue’s people. Everyone entered another space. While ordinary people like Engineer Li didn’t notice any change and found it curious, the members of the equipment department immediately felt the drastic drop in Source Qi, causing an uncomfortable pressure.

"Is everyone here? Can we start?" Engineer Li, the last to arrive, apologized to the people who had been waiting. Those sent by the Daoist Realm and Hell Plane showed enough goodwill, but the alchemist from the Magic Realm watched coldly and discontentedly.

Given the conflict between the two planes and the current situation of needing help, Pei Yan didn’t fuss over it. While assisting Engineer Li to set up the instruments he brought, he completed the mechanization. After finishing everything, he stood in the center, clapped his hands, and smiled, "Alright, now I’m yours! Do whatever transformation you want; the decision is yours!"

Upon Pei Yan’s declaration, the initially reserved top alchemy mechanism experts could no longer contain their curiosity. They swarmed him, curious about his reputation and eye-catching performance in the competition that had marked him as the most intriguing subject for mechanical mages and alchemists. Transforming him opens a path to greater achievements, possibly making their mark in the world of mechanisms by the name Pei Yan, an opportunity they wouldn’t miss.

Looking at Pei Yan, who regretted being too carefree earlier, being watched by a group was uncomfortable. Those at least a few centuries old stared at him with fascinated eyes, scanning his hard metallic body and occasionally pinching it. Even though Pei Yan couldn’t feel on the surface, his soul was still invaded by a creepy sensation.

"Pei Xiaoyou, can we look at the internal structure of your body?" A group from the Daoist Realm led by Elder Feng Tianhe for Pei Yan’s upgrade and transformation, after thoroughly inspecting the mech’s exterior, praised it and looked up at the taller Pei Yan kindly.

"Ah! Look inside? Uh..." Pei Yan removed his mask with difficulty, something he had never tried!

"Is it so difficult? Or do you have reservations about us? We were entrusted by the Spirit Lord to transform Pei Xiaoyou, but if you harbor concerns against us, it might affect the transformation process..." Elder Feng Tianhe, seeing Pei Yan’s expression, thought it was a cornerstone secret not meant to be displayed, and expressed his dissatisfaction with subtlety.

"Elder Feng, you’ve misunderstood! Pei Yan has no such intention towards you." Before Pei Yan could speak, Engineer Li hurriedly explained, "It’s embarrassingly true that Pei Yan’s current body, although equipped with many weapons and materials derived from our base dimension’s technology, cannot yet be integrated with our current technology. This body was crafted purely by his ability to absorb and fuse, so while he may appear as a mech, inside is still human structure. We’ve never had the experience of opening his body for examination."

"Oh, oh! I see, I see!" Elder Feng Tianhe smiled, "Ah, it’s my mistake. I was inaccurate in my expression. I meant to see Pei Xiaoyou’s body structure but didn’t mean to dismantle his body. We can achieve it by other means."

"Oh? What means?" Pei Yan showed interest and curiosity.

Elder Feng Tianhe didn’t answer, but smiled confidently, and with a gesture, he lightly touched his storage ring, and a flash of light followed. Soon, a full-body bronze mirror appeared at the center of the venue. Without Elder Feng Tianhe’s command, two disciples behind him cautiously pushed the bronze mirror before Pei Yan.

Due to the depleted Source Qi, to save time and avoid unnecessary waste, Lin Ruxue had distributed corresponding Source Qi stones before departure, used to replenish Source Qi during the transformation. After the two disciples positioned the bronze mirror, they took out a Source Qi stone and placed it into the slot behind the mirror. As they activated the stone, the mirror emitted a soft glow, Pei Yan’s reflection became blurred, until the complex network of metal and composite materials inside began to appear on the mirror.

"It’s like a CT scan!" Pei Yan looked at the mirror revealing the details of himself, raising his arm and swaying it while admiring, "Isn’t this the legendary Qin King Bone Mirror?"

"Oh? Pei Xiaoyou, you’ve heard of this divine artifact from our Daoist Realm?" Elder Feng Tianhe was quite surprised upon hearing Pei Yan say this.
