Zhang Yu was a freshman in the civil engineering department and a survival expert on construction sites. For the past few months, he had been pursuing wild delicacies found on construction sites, risking his life to obtain the freshest, most delicious, and most expensive ingredients.

A few days ago, he had taken a flying boat, traversing thousands of miles, to reach this war-torn, perilous ruin.

On this land, spanning over a thousand acres, remnants of Core Formation stage cultivators’ magical power lingered, arrays were still in operation, and various polluting materials, harmful beyond imagination, existed… dangers beyond comprehension.

High temperatures, explosions, diseases… all threatened his life, attempting to break down his mental defenses!

And once Zhang Yu was severely injured by these dangers, he would be sent to the accompanying doctor, ending his adventure prematurely!

But what made him most wary were not the deadly threats from the wilderness, but the predators who, like him, were seeking their own targets!

Those older, stronger, and more experienced senior civil engineering students could easily snatch food from him!

To avoid competition with his peers, Zhang Yu had to travel further, seeking precious ingredients growing in secluded, rarely visited places!

At this moment, he cautiously walked through the ruins, his Three-Eyed Divine Power fully activated, wary of any disturbances around him!

His entire being seemed to be shrouded in rolling clouds, scanning across fragments of broken building materials, unknown parts, and exploded equipment!

He would occasionally pick up materials with metallic luster or some unknown tools, appraise them, and then casually throw them back on the ground!

In this perilous ruin, food was always hidden in some unknown corner!

Suddenly, Zhang Yu’s gaze narrowed slightly; he seemed to have found something!

His Formless Cloud Qi transformed into spiraling currents of air, grabbing a cylindrical object and bringing it before him!

This seemed to be a module from a puppet production line!

The Corrosive Abyss Gel membrane it contained possessed acid resistance, high-temperature resistance, and impact resistance; it was precisely the culinary treasure Zhang Yu had been seeking for so long!

Zhang Yu stroked the inner lining of the cylinder, using the knowledge and experience he had gained in recent days to identify it. Soon, a smile appeared on his face, and he began to carefully process this gift from nature!

With a gentle flick of his index finger, a cyan silk flying sword worn on his finger was activated, sweeping a sword light across the cylinder and cutting it into dozens of pieces!

After the sword strike, the cyan silk wrapped around Zhang Yu’s index finger again, but it had lost its mystical power and needed to be nourished with spiritual essence for a day and night to recover!

Picking up the pieces scattered on the ground, Zhang Yu thought, “Luckily, I have the Azure Silk Flying Sword that Zhen gave me, otherwise, even if I found these materials, it would take me a lot of time to process them myself before hiding them or swallowing them!”

Opening his mouth, Zhang Yu swallowed the pieces of Corrosive Abyss Gel membrane!

Although he was ravenously hungry, Zhang Yu did not rush to switch to his College Sacred Body and activate the Earth-Eating Divine Art to digest the food in his stomach!

Because he understood that in this dangerous wilderness, fully digesting would leave him incredibly weak!

So, Zhang Yu simply stored the Corrosive Abyss Gel membrane temporarily in his stomach, to process the day’s harvest all at once after work!

A moment later, Zhang Yu picked up a section of pipe, using a full three Azure Silk Flying Swords to cut it open!

No. 15 Spirit Law Secret Steel was a weaker version of No. 20 Secret Steel, but it still required three sword strikes to cut open!

“As expected, I am still far from being able to digest No. 20 Secret Steel!”

Zhang Yu swallowed the fragments of No. 15 Secret Steel and thought, “Like No. 20 Secret Steel, I’ll store it first. After I strengthen my stomach with Corrosive Abyss Gel membrane, I can use this No. 15 Secret Steel to strengthen my stomach further, and then try to digest No. 20 Secret Steel…”

Just like that, while cleaning the ruins and collecting ingredients, Zhang Yu welcomed the end of his work day!

Taking advantage of the other students’ rush to get massages, he buried the collected ingredients in a pre-prepared pit!

Then, he took out a portion of the Corrosive Abyss Gel membrane, switched to his College Sacred Body, activated the Earth-Eating Divine Art, and began to fully digest this rare food!

“Unfortunately, I have ingredients but no medicine!”

But Zhang Yu knew that he couldn’t be too picky on the construction site, so he shook his head and channeled his magical power to diligently digest the food in his stomach!

Strands of Corrosive Abyss Gel membrane were refined into his stomach, gradually increasing its toughness and resistance, as if gradually coating his stomach with a layer of armor!

And with each strand of Corrosive Abyss Gel membrane refined, his digestive abilities became even stronger, gradually becoming like a giant millstone, grinding down the food that entered his stomach!

In the days that followed, Zhang Yu focused on collecting ingredients, refining ingredients, and cleaning up the ruins!

In just over a week, relying on the Foundation Establishment peak-stage digestive power brought by the College Sacred Body and the Level 20 Earth-Eating Sacred Art, he refined Corrosive Abyss Gel membrane worth over ten spiritual coins into his esophagus, stomach, and intestines, training them as if they were copper walls and iron walls!

So, in the days before the ruins were about to be completely cleared, he finally began to try digesting No. 15 Secret Steel!

First, he consumed seven Azure Silk Flying Swords, cutting the dozen or so metal blocks into hundreds of tiny fragments.

Then, Zhang Yu swallowed the fragments, and the Gluttony Force cultivated by the Earth-Eating Divine Art surged out, working with his Foundation Establishment peak-stage digestive power, he tried to continuously break down this No. 15 Secret Steel!

But feeling the difficult digestion of No. 15 Secret Steel and its gradual shrinking, Zhang Yu activated the Battle Fiend Longevity Loss Art again, temporarily increasing his physical strength level by a full 1.0 levels!

His internal organs instantly erupted like a volcano, bursting out with incomparably violent power, like a giant millstone, constantly grinding against the No. 15 Secret Steel with the blessing of Gluttony Force!

Then, Zhang Yu activated the Level 20 Limitless Vibration Zen, further accelerating his digestive process through high-frequency vibrations!

Feeling the strands of No. 15 Secret Steel being digested by his stomach and strengthening it along with the Corrosive Abyss Gel membrane, Zhang Yu finally felt a hint of satisfaction!

“This No. 15 Secret Steel already requires me to expend all my effort to barely digest!”

“What strength will I reach when I refine No. 20 Secret Steel into my bones?”

A few days later, with the completion of the ruins’ cleanup, the construction site entered the second phase, beginning the construction of the Corpse Construct Factory’s buildings!

And from the start of the building construction, the teachers and students of the Refinement Academy and the Architecture Department also appeared one after another!

However, unlike the Civil Engineering Department, which was aimed at training students, this outdoor Corpse Construct Factory project was simply a money-making project for the Refinement Academy and Architecture Department, and because they mainly focused on design, supervision, and quality control, there weren’t many people who came!

Without the dangerous ruins, Zhang Yu spent his days diligently working while running his College Sacred Body, and striving to move the Earth-Wood Sacred Body’s cultivation method!

Previously, because he had been using the Earth-Wood Sacred Body’s cultivation method to ensure safety, the progress of the Mountain True Form Chapter had slowed down, but now the cultivation progress was rapidly accelerating again!

Under the operation of the Mountain True Form Chapter, Zhang Yu’s body expanded in a circle, and then palm after palm slammed down, fixing the steel bars in front of him!

Looking at the departing students around him, Zhang Yu’s eyes showed dimensional data, reminding, “This is 1.3 millimeters off; the requirement is that it cannot exceed 1 millimeter!”

On this day, he also advanced the Mountain True Form Chapter to Level 10!

After the cultivation method entered Level 10, Zhang Yu felt that the expansion of his body was no longer just systemic but could be localized to expand muscles!

“After Level 10, can I make the body undergo localized muscle expansion?”

After sensing the new power of the cultivation method, Zhang Yu looked at the messages in the group and helplessly urged, “Hasn’t the blueprint from the Architecture Department arrived yet? Can you hurry them up? We’ve been waiting for almost an hour!”

After a busy day and night, it was finally time to get off work!

Zhang Yu usually couldn’t bear to waste the Spiritual Realm Network or the equally expensive Sky-Patrolling Flying Sword’s network!

But at this moment, Zhang Yu held the Profound Creation Relic, absorbing the high-quality magical power within!

At the same time, he connected to the Spiritual Realm Network within the construction site, reported his safety to Bai Zhenzhen and Zhang Pianpian, asked Yu Xinghan for the lecture videos, and greeted Le Mulan!

“Zhen, those senior brothers of mine went to get massages again! Of course, I didn’t go; there are only six masseuses, working overtime every day, not even having time to shower. I find them dirty!”

Life on the construction site was so fulfilling that Zhang Yu felt like he was a piece of steel being repeatedly forged, constantly being tempered in high temperature and high pressure, progressing on the path of immortality every second!

After half a month, not only had his cultivation greatly improved, but he also became more familiar with the construction site, and his construction experience became increasingly rich!

Looking at the dimensions of the steel bars in front of him, Zhang Yu said to Che Yufei, “It’s only two millimeters off; I think it’s close enough. We’re not building immortal artifacts!”

Che Yufei frowned, about to say something, but seeing Zhang Yu slip him a piece of No. 20 Secret Steel, he raised his eyebrows slightly, and discreetly stuffed it into his sleeve, “I’ll let it go this time, but you can’t do this again next time!”

After seeing Che Yufei off, Shi Yunxiang said, “Teacher Tu said in the group that the blueprint has been sent over.”

Zhang Yu said, “What blueprint are you waiting for? I’ve already installed that floor. Those designers don’t understand the situation as well as we do on-site!”

“It’s time to get off work. I’m leaving first!”

Shi Yunxiang returned to his room, only to find Che Yufei and the others here. He asked in confusion, “Aren’t you guys going to get massages?”

Che Yufei said helplessly, “Those few masseuses haven’t showered in a long time. We all think they’re dirty. Only Zhang Yu went!”

Accompanied by a soft “boom!”

Zhang Yu dug open the earthen pit he had buried, and took out a piece of No. 20 Secret Steel from it!

With Che Yufei and the others no longer getting massages these past few days, Zhang Yu simply used massages as an excuse to sneak out and eat his daily meal!

“Tomorrow the masseuses will shower. Che Yufei and the others should continue to go get massages to relax!”

Zhang Yu looked at the No. 20 Secret Steel!

After he strengthened his stomach with No. 15 Secret Steel, it was finally time to digest this No. 20 Secret Steel!

This precious material used to protect the core parts of puppets, with a strength comparable to some body parts of Foundation Establishment peak-stage body refiners, not only explosion-proof and impact-resistant, but also able to evenly absorb martial arts force!

Zhang Yu had previously used the Azure Silk Flying Sword to cut it, consuming seven strands of Azure Silk power a day, only barely cutting off a piece the size of his palm!

At this moment, Zhang Yu’s mouth, stomach, and chest suddenly swelled open!

It was because he had advanced the Mountain True Form Chapter to Level 20, allowing him to temporarily expand his esophagus, stomach, and other internal organs when the cultivation method was in operation!

And after cultivating the Mountain True Form Chapter to Level 20 a few days ago, his Earth-Wood Sacred Body had finally reached the second layer!

Superior Earth-Wood Sacred Body (8/8): During the Foundation Establishment stage, the consumption of lifespan from exercising, eating, and taking medicine is greatly reduced!

The Earth-Wood Sacred Body allows you to live to old age and work until you die, always on the road to work!

“What a great Sacred Body. With this Earth-Wood Sacred Body, I can also activate some cultivation methods and take some lifespan-reducing medicines more unscrupulously!”

“It’s also good that I’ve only spent at most a year of lifespan during this time. I still have plenty of lifespan to burn!”

Looking at the second effect of this Earth-Wood Sacred Body, Zhang Yu smiled slightly and swallowed the No. 20 Secret Steel in his hand!

Then, he activated the Earth-Eating Divine Art first. The strands of Gluttony Force condensed within his Dantian had already risen and slammed towards the No. 20 Secret Steel in his stomach!

Immediately afterward, the muscles all over his body suddenly tensed, his heart began to beat violently, and streams of blood gushed out from his heart like a rushing flood!

The eruption of qi and blood also made Zhang Yu’s skin turn a crimson color, as if it were about to bleed!

The Level 20 Battle Fiend Longevity Loss Art had erupted with a bang, and not just an ordinary eruption, but a double eruption!
