What’s the point of cultivating immortality if you don’t have money?.

Chapter 402 Busy Zhang Yu

As Zhang Yu's refining level of Azure Sand improved to Level 2, countless images of refining Azure Sand flashed through his mind: the circulation of various magical powers and qi, the handling of materials, the control of the heat, the details of spraying fiber composite films, and the experience of stabilizing magical power circuits...

One after another, refining memories surfaced in Zhang Yu's mind, giving him a sudden and deeper understanding and appreciation of the refining of Azure Sand.

So when he tried refining azure sand with one-tenth of the materials again, the success rate increased dramatically.

The quality of the azurite sand has also seen a visible improvement.

Looking at the finished azure sand that Zhang Yu had refined, Ye Xingli was slightly surprised: "The color is bright, and the impurities and purity seem to be much better than before... Is it grade 2 azure sand?"

Was it just luck? Or did he really improve quickly?

Ye Xingli continued to observe, but soon discovered that Zhang Yu had started to arbitrarily compress the refining time again, and the produced azure sand had returned to the level 1 level.

After six hours of practice, Zhang Yu, through repeated attempts, managed to reduce the refining time of the azure sand to approximately 15 minutes.

"If the material is compressed to one-tenth, that's 0.003 spirit coins."

"The rental fee for the venue and equipment is 0.7 spirit coins for 6 hours, which, after splitting with Ye Xingli, is 0.35 spirit coins."

"If we maintain the refining process every 15 minutes, we can complete 24 refining processes in 6 hours."

Zhang Yu silently calculated in his mind: "If we calculate it this way, the cost of refining once is reduced to about 0.01758 spirit coins."

"And this is not even the limit."

Zhang Yu thought of his Wuxiang Warrior and Shenhan Warrior.

Just like how you can use the Formless Warrior and the Deep Cold Warrior to do the work on a construction site, he felt that the same could be done in the same way when refining weapons.

Zhang Yu thought to himself, "The compression of materials and time can be fixed now. Next time... I'll activate the fourfold thinking and see if I can refine four portions of Azure Sand simultaneously."

"If successful, not only can costs be further reduced, but cultivation efficiency can also increase dramatically once again."

"In addition, if I sell some of the Azure Sand after continuously refining it to recoup my losses, the cost of the spirit coins can be reduced even further."

Thinking of this, Zhang Yu looked at Ye Xingli beside him and asked, "Senior, if I want to sell some of the products I made as practice in the future, where would be the most convenient place to ship them?"

Ye Xingli thought about Magnetism True Lord's instructions and said directly, "If you trust me, you can just leave your things with me from now on."

"I have some connections in the weapon crafting department, I can help you sell it."

"However, basic weapon crafting products won't fetch a high price; at most, they'll only allow you to break even."

Zhang Yu nodded quickly and said, "I know, it's okay, as long as I can break even."

After leaving the laboratory, the two said their goodbyes.

As Ye Xingli watched Zhang Yu's departing figure, she sent a message to Magnetism True Monarch: Master, Zhang Yu and I have come out of the laboratory.

Magnetism True Lord: How did Zhang Yu perform?
Ye Xingli: Her talent in weapon crafting is alright; she managed to craft a level 2 Azure Sand within 6 hours.

Ye Xingli: But her attitude is very problematic. She likes to arbitrarily change the portions and time even though she's just starting out.
Ye Xingli briefly described what she had seen.

Magnet Lord replied: I understand.

Magnet Lord: If he wants to sell his produce in the future, then temporarily help him consign it.

Magnet Master: Regarding the lab, we could also split the costs with him.

Hearing Magnet Lord ask her to help Zhang Yu in this way, Ye Xingli finally couldn't suppress her doubts.

She asked, "Master, Zhang Yu is a student in the Civil Engineering department, right? His talent for weapon crafting isn't particularly outstanding, so why are you helping him so much?"

Magnet Lord: Director Gao of the Civil Engineering Department wants to transfer his disciple to the Weapon Forging Department.
Magnet Lord: Although I don't really recommend him do that.
Magnet Lord: But given our centuries-old friendship, since he insists, then even if it means taking a loss, I should still help him.

Looking at the message sent by Magnetism True Lord, Ye Xingli couldn't help but sigh at the friendship between Magnetism True Lord and Director Gao.

She thought to herself, "Sure enough, it wasn't Zhang Yu, a civil engineering student, who attracted Master, but rather Director Gao."

Ye Xingli also felt that this made sense. After all, a civil engineering student would be just like a security major, a "junior college student" in Wanfa University. With Master's high standards, how could he possibly be interested?
I'm afraid you'll have to accept a red envelope before you can even say a word.

"But Master and Director Gao... is it a friendship between ancient cultivators?"

"Although Master has kept up with the times and has been learning cutting-edge immortal techniques and keeping up with the trends in Kunxu, he is still an ancient person after all. In his mind, he is still inevitably influenced by the dregs of ancient culture."

Just as Ye Xingli was pondering, Magnetism True Lord sent another message.

Magnet Lord: This matter is currently classified. Even if you ask me and Director Gao in person, we will not admit it.
Magnet Lord: Remember not to tell anyone.
Ye Xingli: Master, don't worry about my mouth. Even if someone offers me 1000 spirit coins, I won't tell anyone.

……

Meanwhile, Zhang Yu was on his way to the construction site on the 667th floor.

He first looked at the Azure Sand Level 2 (10/20) on the Feather Book, and then looked at another weapon crafting technique on the Feather Book.

天青采云兜0级（0/1，天青砂2/5级）
This Azure Cloud Pouch was a magic weapon blueprint that Zhang Yu learned in the weapon crafting course. It is a magic weapon that can be used to store Azure Sand.

With the infusion of magical power, it becomes possible to perform large-scale spraying and recycling of azure sand.

Just like Zhang Yu's cultivation techniques, many weapon-refining skills also have threshold requirements to master.

The refining of azure sand, for example, requires magical power and qi. And to obtain the Azure Cloud Gathering Pouch, one must first master certain azure sand refining techniques.

"Whether it is a magic weapon or a magic body, in addition to the requirements of realm, Dao heart, and magic power, there are often various prerequisite requirements for refining techniques."

Zhang Yu thought to himself, "To cultivate step by step to the point where I can refine my physical body into a magical body, in addition to cultivation level, I need to master a large number of prerequisite weapon-refining techniques."

"There's still a long way to go."

"However, there are so many crafting techniques, so there's probably no need to improve every single one to the extreme in the future. Just enough to get by is fine."

As for more distant goals, such as having his own weapon-refining laboratory or establishing his own production line... Zhang Yu can only dream about them now.

Arriving at the construction site familiar with the place, Zhang Yu saw a series of formless warriors appear around him.

Then, with a flick of his wrist, he scattered a handful of azure sand onto the bodies of these formless warriors.

As the surging internal energy within the Formless Warrior surged, it revealed wisps of azure sand, giving the Formless Warrior a more solid and grounded appearance.

Zhang Yu thought to himself, "Azure Sand can increase the efficiency of Qi transmission and reduce the consumption rate, which should improve my work efficiency."

So Zhang Yu then controlled the Formless Warrior to work and earn money on the construction site, while he himself was shrouded in a cloud of Formless Cloud Qi and began to cultivate the 7th technique of the Martial Saint Body.

Several hours passed, and as dawn broke, Zhang Yu calculated his wages for the day and thought to himself, "Construction efficiency has improved by about 5%."

"Not bad, not bad. If the grade of the azure sand is higher in the future, the efficiency of improvement should be even higher."

"In this way, even if Senior Ye Xingli doesn't sell many Azure Sands on consignment, I can still use them to increase my income at the construction site."

Thinking of this, Zhang Yu became even more motivated.

In the days that followed, Zhang Yu would rent the weapon-refining laboratory once or twice a week to practice his weapon-refining skills.

The rest of the time, he attended classes during the day and worked on construction sites at night, while also practicing the martial arts holy body techniques.

In addition, he also needs to take time to study weapon crafting courses in Taiqing Realm, absorb 200% quality mana to improve the quality of his mana, and go to Hammering Heart Residence to temper his Dao heart...

……

In the laboratory.

Ye Xingli glanced at the three formless warriors beside her and thought to herself, "Such strong thinking ability."

"However, is it really good to multitask like this and produce multiple portions of Azure Sand at the same time to improve your weapon-refining skills? Improving weapon-refining skills is not about just doing more refining attempts."

In Ye Xingli's opinion, unless it's about meeting production targets, it's better to focus on refining a batch of Azure Sand, paying attention to details such as materials, steps, time, heat, magic power, and qi, and constantly learning and adjusting, as this will be more effective in improving one's skills.

The next moment, Ye Xingli's gaze suddenly shifted, looking at the azure sand that had been successfully refined in front of the Formless Warrior.

"Level 3 azure sand?"

"interesting."

Ye Xingli thought to herself, "Although he likes to act recklessly, Zhang Yu's talent in weapon crafting seems to be stronger than I expected."

However, she didn't care too much about it, since when Ye Xingli first refined Azure Sand, she directly refined Level 5 Azure Sand.

Turning her head, Ye Xingli continued interviewing her new spirit.

"You graduated from Hehuan University before you died? May I ask what your primary gender was?"

"You're a colonel? Sorry, this recruitment only hires soul cultivators who have graduated from the top ten."

"Heavenly Demon University? Welcome to join us. In the future, just treat my right hand as your own home."

……

Zhang Yu had just left the laboratory that day when he received a message from Gongshu Jin.

Upon seeing the message, Zhang Yu's eyes lit up: "Is the buffet about to start?"

At the same time, Ye Xingli looked at Zhang Yu and said, "You're going to the party later, right? After all, it's a celebration for the Civil Engineering Department."

Zhang Yu nodded. He already knew that the party was arranged by Mo Shangjin, mainly to celebrate their second-place finish in the inter-school league.

Ye Xingli casually said, "Then let's go together, I'm going to participate too."

Zhang Yu followed Ye Xingli to the 650th floor of Wanfa University. As soon as they stepped out of the anti-gravity passage, they saw Gongshu Jin waiting outside.

Gongshu Jin was taken aback to see Zhang Yu walking with Ye Xingli.

Compared to when he first met Ye Xingli last year, the current Ye Xingli is vastly different in Gongshu Jin's eyes.

That means the 15th place in the weapon crafting system on the other person's head has become the 8th place.

With this ranking in the weapon crafting department among the three top departments, Ye Xingli was already considered a first-rate student of Wanfa University in Gongshu Jin's eyes.

Seeing the two chatting and laughing, Gongshu Jin thought to himself, "When did Zhang Yu and Ye Xingli become so close?"
