Right then, a thunderous roar echoed from afar. Zhang Yu turned to see a surge of chilling air erupt, freezing half the body of a senior student.

However, the senior student roared fiercely an instant later, his body ablaze with fiery light, suppressing the encroaching cold.

He gasped, “Thankfully, some time has passed, and the residual spiritual power of the Golden Core has weakened considerably. Otherwise, that strike just now…”

Witnessing this scene, everyone grew even more cautious. Zhang Yu activated his Third Eye Divine Power, maintaining a 360-degree field of vision, alert to any disturbance!

As Zhang Yu stirred up a whirlwind of Qi, carrying away a piece of shattered wall, he suddenly felt a wave of icy-cold aura rushing towards him!

Beneath the broken wall, a section of steel wrapped in layers of flesh pulsed rhythmically, as if breathing!

At the same time, intense resentment, visible even to Zhang Yu’s ordinary eyes, surged forth from the steel, spreading in all directions!

Zhang Yu exclaimed, “Resentment!”

Fu Ji warned, “Be careful! Such potent resentment, if it invades your body, will cause at least a few days of illness, or even a mental shock, causing a regression in your Dao heart!”

At that moment, several senior students arrived. Che Yufei declared, “It’s resentment alloy, used to craft puppets!”

Zhang Yu asked, “Should we ask Master Tu how to handle this?”

Che Yufei patted Zhang Yu’s shoulder, excitement in his voice, “Ask the teacher? Why bother? I’ll just ask the scrap dealer tonight what the current price is!”

“As usual, we give 50% to the teacher, and we split the remaining 50%!”

Seeing the senior students’ matter-of-fact manner, Zhang Yu suddenly had a deeper understanding of the Earth and Wood Department!

Soon after, another deafening crash resounded. A metallic giant palm rose into the sky, slamming a Foundation Establishment cultivator away, causing him to bleed from all orifices and suffer multiple fractures!

Zhang Yu later learned that the cultivator had unearthed a partially completed puppet arm. The arm had unexpectedly activated, blasting him away!

As Zhang Yu grasped a support beam, his Third Eye Divine Power detected an unusual surge of spiritual energy around him!

He instantly activated his Time Fragment Ink Pupils, perceiving the world as if slowed down!

He saw the ground beneath his feet slowly rising, as if the earth was transforming into a massive maw, about to swallow him whole!

The Battle Demon Longevity Destruction Art activated with a roar, unleashing a 1.0-level physical augmentation. Combined with Zhang Yu’s own strength, this allowed him to dart away with a whoosh!

The spot where he had stood was engulfed by a small mound of earth!

Zhang Yu secretly sighed in relief, “Is that the factory’s protective formation?”

Then, he looked at the half-section of support beam in his hand, his heart filled with joy. The material was clearly extraordinary!

However, Zhang Yu hesitated, then looked up at the massive factory ruins before him. In the end, he decided not to handle the material himself. Instead, he sought out Che Yufei!

Che Yufei saw Zhang Yu’s initiative in handing over the support beam, his lips curving into a slight smile. He patted Zhang Yu’s shoulder and said, “You understand the rules. I’ll transfer your share as soon as the recycling fee arrives!”

Zhang Yu seized the opportunity to ask, “What material is this support beam?”

Che Yufei introduced it expertly, “Oh, this? Third-grade special alloy steel, capable of withstanding relatively high load requirements. It’s often used as a support beam!”

And so, in this ruin filled with residual Golden Core spiritual power, dangerous materials used to craft puppets, and remnants of the factory’s protective array, Zhang Yu cultivated his techniques while clearing debris and collecting materials. He constantly learned the properties of various materials through Che Yufei’s expertise!

Although dangers lurked everywhere, Zhang Yu, with his Third Eye Divine Power’s sensing abilities, the Time Fragment Ink Pupils’ time-slowing ability, and the Earth and Wood Sacred Body’s formidable resistance, was able to safely complete his work!

Just as Zhang Yu and the others had been busy all night, starting their third dose of medicine, Gongshu Jin and the others finally finished their online classes and began their work and cultivation!

“Everyone, I’ll start first!” Mo Shangjin waved to the others, then nodded to Gongshu Jin, “Junior Gongshu, do your best too!”

Mo Shangjin knew that Gongshu Jin was a student whom Director Gao intended to focus on cultivating in the Heavenly Kunlun Mountain Moving Divine Power. Since they met, he had made many attempts to show goodwill to this junior whose name shared a character with his own!

Under Gongshu Jin’s admiring gaze, Mo Shangjin floated in the air. Accompanying his hand seals, the Heavenly Kunlun Mountain Moving Divine Power erupted, uprooting the surrounding trees and moving layers of mountain rock!

Gongshu Jin understood that Mo Shangjin was using the Heavenly Kunlun Mountain Moving Divine Power to adjust the mountain’s terrain little by little, in order to draw in the spiritual veins!

“If spiritual veins are like a long river, then adjusting the mountain terrain is like changing the river’s course, able to straighten the spiritual veins and lay the foundation for array formation!”

Then, Gongshu Jin looked at the other senior disciples. Some transformed into giant dragons, opening paths on the ground, excavating tunnels, and creating transport routes leading to the underground!

Others clasped their hands together. A high-temperature force field suddenly covered a hundred-meter radius, refining large quantities of collected metal materials, converting them into brand new building materials!

Gongshu Jin thought to himself, “The Heavenly Kunlun Mountain Moving Divine Power goes without saying, the Earth and Wood Department’s military-grade martial skill, renowned throughout Myriad Law University!”

“And the Stellar Meridian Piercing Great Art, and Scarlet Fire Flame God Art are all expensive, requiring costly pills and spiritual bones, and are massively expensive. They emphasize foundation and accumulation before full bloom!”

“Of course, once you master them, earning spirit coins becomes easier, and the risks and physical wear and tear are reduced.”

Gongshu Jin understood that it wasn’t that the Earth and Wood Department’s teachers were unwilling to teach these to the poor students, but that the poor students couldn’t afford to learn them. They could only learn techniques that destroyed their bodies and forced out their potential!

At first, those techniques for the poor could barely keep up with them, but soon, due to insufficient limits, they would be left far behind. At that time, their daily income on the construction site would be tens, even hundreds of times lower!

At this moment, watching the senior disciples display their extraordinary abilities, Gongshu Jin also felt inspired. Full of fighting spirit, he turned and walked towards his own work station!

He spread out his hands, and two fierce cyclones had already formed on the newly implanted spiritual bones, beginning to activate his newly cultivated technique, the Nine Earth Nether Force.

In the blink of an eye, the prepared cement, sand, mineral powder, spirit stones, and other materials were drawn into it, transforming into a gray tornado rising into the sky!

When Gongshu Jin and the others began their work, the massive movements also attracted Zhang Yu’s attention!

Looking at the tornado rising into the sky, the countless mud and sand flying into the air, and the violent tremors coming from the earth, Zhang Yu felt a sense of emotion.

“Compared to those guys, we’re practically just ordinary construction workers!”

“No, it should be said that those guys are like giant engineering machines?”

Shaking his head, Zhang Yu focused his attention back on his own work!

Another day passed, and the students welcomed an hour of rest!

Zhang Yu first switched the chained spiritual item set to the Grand Academic Sacred Body to take medicine, then returned to his room and switched to the Martial Dao Holy Embryo to accelerate self-healing!

He thought, “As my cultivation gradually improves, the Martial Dao Holy Embryo’s blessing effect is getting weaker and weaker!”

“After all, a Qi Refining stage set cannot be used forever!”

Opening the Spirit World Network, Zhang Yu looked at the received messages and replied to them one by one!

Just then, Che Yufei and the others walked in!

Che Yufei looked at Zhang Yu and said, “What are you doing here? People can’t just work overtime and cultivate all day, they need to relax a little!”

“The massage therapists have already set up a massage room. There’s a promotion today, let’s go!”

Faced with Che Yufei’s invitation, Zhang Yu, who was constantly recovering from physical wear and tear under the dual effects of the Martial Dao Holy Embryo and body activation, naturally shook his head and refused. He didn’t want to waste money!

Che Yufei said, “If you don’t get a massage on the construction site, how will you survive and earn more money?”

“Hurry up!” Shi Yunxiang had already walked out. “I’ll go pick first!”

Seeing Zhang Yu repeatedly refuse, Che Yufei also shook his head, too lazy to persuade him, and left first!

Just then, a message popped up in Zhang Yu’s eyes from Bai Zhenzhen: “Yuzi, are you off work?”

Zhang Yu: “Yeah, I’ll meditate for a while, then I’m going to work overtime! Internet fees are expensive, I’ll turn it off later!”

Bai Zhenzhen: “I heard that the Earth and Wood Department needs massages to eliminate physical wear and tear after work, aren’t you going?”

Zhang Yu: “My colleagues all went, I didn’t go, there’s no need!”

Bai Zhenzhen: “Are you sure? You should go, don’t break your body!”

Zhang Yu: “It’s okay, I won’t waste the money!”

Bai Zhenzhen: “Sigh, Mom is useless, I can’t even send my son massage money.”

Zhang Yu: “Cultivate hard, if you want to be filial, you can do it next time you see Dad!”

After chatting casually with Bai Zhenzhen, Zhang Yu also ended his initiative in breathing exercises. Feeling that his body had recovered to a reasonable level, he once again went to the ruins alone!

In the next few days, Zhang Yu constantly took medicine, constantly cultivated, and constantly worked overtime. In the crisis-ridden environment, he both damaged himself and repaired himself!

At the same time, his knowledge of the various materials in this ruin became deeper and deeper. Every day, while the students went to get massages, he took the opportunity to collect materials and complete the devouring!

The first material he chose to digest was the No. 20 Spiritual Secret Steel, originally used to manufacture the protective armor of the puppet factory’s puppet core!

This secret steel could prevent explosions and impacts, and could also evenly absorb martial arts power. It had the strength comparable to a peak Foundation Establishment Body Refinement expert!

Once he could rely on the Foundation Establishment peak digestive power brought by the Grand Academic Sacred Body, coupled with the level 20 Soil Eating Divine Art, to refine this No. 20 Spiritual Secret Steel into his bones, further strengthening his bones, he would truly have an indestructible skeleton strong enough to rampage in the Foundation Establishment stage!

But after Zhang Yu finally picked up a little bit, he found that it was difficult for him to digest this material. It might take ten and a half months to strengthen only a few finger bones!

Zhang Yu thought, “What to do? Try cultivating another technique?”

“Try a medicine to enhance digestion?”

Zhang Yu thought for a while and rejected the various options one by one!

Finally, he thought, “Although the Grand Academic Sacred Body has given me powerful digestive abilities, the essence of my digestive tract is still affected by my own physical strength!”

“If I want to speed up the digestion of No. 20 Spiritual Secret Steel, I need to make my digestive tract more resilient and stronger… like putting a layer of armor on my digestive tract!”

Thinking of this, a flash of light appeared in Zhang Yu’s eyes, and the data of various materials in the scene appeared in his mind!
