When Zhang Yu returned to the dormitory and shared his thoughts, Zhang Pianpian told him to wait a moment and then sent him a document.

Zhang Yu asked curiously, “What is this?”

Zhang Pianpian replied, “The pharmaceutical factory where the explosion occurred belongs to the Mingxin Group.”

“In theory, the Mingxin Group is a company affiliated with the Pill Cauldron Sect, one of the Ten Great Sects. Its main task in the second layer is to manufacture medicines and sell them to those above.”

“The document I sent you is a list of the factory’s equipment, building materials, and decoration materials.”

“And the raw material procurement list for this pharmaceutical factory!”

Zhang Pianpian added, “But just having the names isn’t enough, you need to be able to recognize the items yourself!”

Zhang Yu glanced at the material list and felt that with the help of the civil engineering textbooks, he should be able to recognize about seventy or eighty percent of them!

“But these pharmaceutical raw materials…”

Zhang Yu suddenly thought of Le Mulan!

So, after school that day, Zhang Yu began to consult Le Mulan, asking her to help investigate the properties of some raw materials and how to identify them!

After all, Le Mulan was a pharmacology student. Relying on her knowledge framework and the textbooks in the grand library, she gradually helped Zhang Yu identify most of the raw materials!

So, in the days that followed, Zhang Yu spent every day, besides working, picking, identifying, and eating!

To have more time for these activities, he even applied for a leave of absence from the department!

And the civil engineering department approved Zhang Yu’s leave very quickly!

After all, what was wrong with a student wanting to skip classes to earn more money? Besides, it was their own civil engineering project!

Inside the factory area!

“Found food again.”

Zhang Yu picked up a few pieces of metal shards, swallowed them in one gulp, and thought to himself, “Third-grade spiritual alloy, used to make valves in high-temperature and high-pressure environments!”

“Good for using rice to strengthen my bones!”

As the Gluttonous God Art circulated, Zhang Yu felt a subtle heaviness in his hand bones, with slight changes in density and weight!

A moment later, Zhang Yu grabbed a large handful of black fragments and swallowed them: “Polymer, used to make buffer components in high-wear environments, perfect for strengthening my joints!”

“Ethereal Membrane Marrow, a biological material refined from venomous insects, resistant to acids, alkalis, and high temperatures, strong toughness, impact resistance, originally used as a key material for drug filtration, now let it fuse into my periosteum!”

Because the entire factory area’s repair work would only last for a maximum of 15 days, and considering that the restoration of network and surveillance might be even sooner, Zhang Yu had a clear plan for his consumption!

“Instead of eating everything randomly, strengthening a little here and a little there!”

“Better to focus on collecting a few kinds of materials, prioritizing the improvement of bone strength!”

After determining his eating priorities, Zhang Yu was like a customer who rushed into a seafood buffet and focused on eating a single category!

With wave after wave of consumption, he felt his bones becoming increasingly resilient and solid, and his body becoming heavier than before!

And besides the materials, medicines and pharmaceutical raw materials… Zhang Yu didn’t give up either!

Especially after hearing Zhang Pianpian say that the medicines produced by this pharmaceutical factory were all sold to those above, he became even more interested!

“This is the extract of Wu Xia Fei Guan, long-term consumption can improve hearing and make the ears and eyes sharper.”

“This is the essence extracted from Zi Bai Wen Zhi, which can enhance the fire attribute within one’s mana!”

“This is Jing Xue Su, an extract of Jing Xue Cao, used to increase the body’s sensitivity!”

After identifying and trying more and more raw materials, Zhang Yu felt disappointed!

“After all, it’s a factory that produces in batches, just eating these raw materials, I’m afraid I’ll be wasting my time!”

So, Zhang Yu ultimately turned his attention to the leaked semi-finished drug products!

It wasn’t that he didn’t want to pick up finished products, it was just that the finished products had already been picked up by the pharmaceutical factory itself during the first wave of disaster relief!

And the biggest problem with semi-finished products was the uncertainty – whether they would have any effect, what effect they would have, was difficult to confirm before consuming them!

But fortunately, with the help of the drug list provided by Zhang Pianpian and the assistance of Le Mulan, Zhang Yu could confirm that the things produced by this pharmaceutical factory should not exceed his tolerance under the University Sacred Body!

So, Zhang Yu could only try them one by one, feeling like he was drawing a lottery every day!

There was a kind of black, pasty substance that, after Zhang Yu swallowed it, gradually made him feel a disturbance in the spiritual root within his qi sea. His spiritual root fusion was faintly improving!

There was also a kind of yellow medicinal powder that, after Zhang Yu ate it, made him feel an itch all over his skin, and he actually grew several scales. He was so frightened that he quickly stopped and pulled the scales out!

There were also some semi-finished products that, after he ate them, made him feel a lightness in his sea of consciousness, and the effectiveness of his cultivation techniques improved!

There were even some semi-finished products that stretched his tendons and bones, expanding his body by a size, and his normal height rose to 2.05 meters, forcing him to actively shrink his body!

In short, these semi-finished products varied in appearance and effect, and Zhang Yu could hardly distinguish them, so he could only eat them casually, try them casually, and feel his body being strengthened from time to time!

But the most impressive thing was the golden pill he picked up, which was also the only finished pill he picked up during the entire pharmaceutical factory’s repair project!

When Zhang Yu swallowed this golden pill, he felt an overflowing energy all over his body, a kind of unspeakable vitality and vigor!

It was not until later, after Zhang Pianpian and Le Mulan identified it, that he knew this was a longevity pill. The moment he swallowed this pill, it would increase his lifespan by about one year!

“Longevity pill?” After Zhang Yu knew this, he felt extremely strange: “The list of medicines produced by this pharmaceutical factory doesn’t include longevity pills, does it?”

To this, Zhang Pianpian did not answer him in detail as usual, but said indifferently, “Longevity is a very special resource, of great importance… Don’t ask too much now, don’t interfere too much, don’t think too much!”

Zhang Yu could only suppress the doubts in his heart, but in his mind, he speculated whether this attack on the pharmaceutical factory was related to this longevity medicine?

In the blink of an eye, 15 days passed. With the improvement of the network, the repair of the formations, and the restoration of surveillance… in the last few days, Zhang Yu gradually found no more opportunities to freeload!

Yu Xinghan looked at Zhang Yu returning to the dormitory and couldn’t help but ask, “You’ve been working so hard every day, how do you feel like you’ve gained a little weight?”

Zhang Yu said faintly, “Overworked and fat!”

Yu Xinghan couldn’t help but ask again, “You seem to have grown taller too?”

Zhang Chou said casually, “The cultivation technique is good, and I’ve had a second growth spurt!”

In these days, relying on a large amount of food, Zhang Yu’s strength had undergone a great leap forward!

In particular, his bones were refined with various high-strength materials, and all aspects of performance were greatly improved. The strength was far beyond what it was half a month ago!

Zhang Yu thought to himself, “With my current high-density, high-strength bones, coupled with the Earth and Wood Sacred Body, the resistance is truly amazing!”

In particular, this kind of bone strengthening would not change with Zhang Yu switching chain method suits and could be used with his Earth and Wood Sacred Body, University Sacred Body, Martial Dao Holy Embryo, and other suits!

And the comprehensive strengthening of the bones also led to the continuous progress of Zhang Yu’s physical strength, which had now reached level 12.31!

The spiritual root fusion had also broken through after multiple doses of semi-finished drugs. Currently, it had reached 90% spiritual root fusion!

His normal body size had reached 2.08 meters, and his weight continued to increase with the changes in his height and bones, further enhancing his physical explosive power!

In addition to this, the basic data had also improved in various ways. His Dao Heart had reached level 12 (68.1), and his mana had broken through to 401.1!

Zhang Yu felt that after this wave, various materials, medicines… if he were to spend money to buy them, it would probably cost no less than twenty or thirty spiritual coins!

At this moment, he only had one exclamation in his heart: “Unfortunately… I can’t take them out!”

“Forget it, who takes out from an all-you-can-eat buffet!”

“I just don’t know if my current level is enough to get into the top three in the class!”

“After class tomorrow, I’ll update the data and see what the rankings look like after the update!”

Since taking leave, Zhang Yu had been running to the construction site every day and hadn’t been to class for half a month, relying entirely on Yu Xinghan’s notes to help him make up for the course content!

Just then, with the opening of the dormitory door, Le Mulan walked in!

Zhang Yu quickly said, “Come, let me bleed some more for you. Your Foundation Establishment exam is in a few days, right?”

Although he had been focusing on work and eating these days, Zhang Yu had not forgotten to bleed some blood for Le Mulan to take!

In particular, he had been eating too well these days, and the effectiveness of his blood had become much stronger, allowing Le Mulan to enjoy a wave of benefits as well!

Yu Xinghan on the side said, “Bro, give me some too!”

Just as Zhang Yu was bleeding, notifications floated in his vision!

A material theft incident occurred in the B2 area of the Mingxin Pharmaceutical Factory, with over 300 tons of materials lost!

After investigation by the security team, it was found that workers Zhang Hetian, Zeng Huaian, and more than ten others were suspected of the incident. After questioning, the suspects confessed to the matter…

Zhang Yu looked at the notification and thought to himself, “300 tons? They actually dared to take that much? No… how did they take it? Was it really these dozen workers who took it?”

Just then, another notification floated up!

Employee Zhang Yu, in this repair project, dared to fight and was the first to charge forward. He completed 1,200 tons of garbage cleaning work alone and was selected as a model worker. A special announcement is issued to encourage him!

Zhang Yu thought to himself that he cleaned up the garbage while picking things up, transporting it out time after time, and he didn’t realize he had transported so much!

At the same time, the wages for the past 15 days had also been credited, causing Zhang Yu’s account balance to suddenly soar to 12.51 spiritual coins!

Just as Zhang Yu was looking at the number of spiritual coins and feeling excited, a message from Tu Lishan also arrived!

“Zhang Yu, your performance this time was very good!”

“Director Gao thinks highly of you!”

“There’s an outdoor project next month. The department plans to select a batch of outstanding students from all grades to cultivate. Are you interested?”

After seeing Zhang Yu being selected as a model worker, Ying Xin felt a sense of unease!

Next, through some channels, after confirming that Zhang Yu had replaced her and obtained the opportunity to participate in the outdoor project, she felt even more resentful!

“Why?”

“It’s a foregone conclusion that Gongshu Jin was selected, so that’s fine… why can this Zhang Yu replace me?”

When she expressed her doubts to Tu Lishan, Tu Lishan responded with a chuckle, “Director Gao wants to select some civil engineering seeds who have good talent, strong strength, can endure hardship, and are willing to work hard for money.”

Tu Lishan thought to himself, “Only a sixth-generation civil engineer and you want to be on the table, want to not do dirty and tiring work, want to wash off the earthy smell on your body? Does the civil engineering department need your kind of person? The director is looking for useful tools, not delicate porcelain. Everyone is so good at slacking off and unwilling to work hard, how can the department make money?”

He chuckled to himself, “Following Gongshu Jin to cultivate every day, thinking that you are also one of the people above!”

“But you don’t know that university may be the closest you will ever get to them in your life!”

Ying Xin on the other side still felt unconvinced and said, “I can also endure hardship, I can also work hard!”

“And my strength is stronger than Zhang Yu’s. Shouldn’t university look at strength and rankings?”

“I want to have a showdown with Zhang Yu.”

Tu Lishan smiled when he heard this and said, “Okay, then let’s see who is more hardworking and who can endure hardship better!”
