As Zhang Yu’s proficiency in refining Tianqing sand reached Level 2, countless images of refining Tianqing sand flashed through his mind: the operation of various mana and Gang Qi, the manipulation of materials, the control of the heat, the details of spraying the composite fiber mbrane, the experience of stabilizing mana circuits...
One mory after another of refining erged in Zhang Yu’s mind, giving him a sudden and deeper understanding and insight into the refining of Tianqing sand.
Thus, when he attempted to refine Tianqing sand again with one-tenth of the materials, the success rate suddenly increased significantly.
Moreover, the quality of Tianqing sand visibly improved.
Ye Xingli, who was standing aside, looked at the finished Tianqing sand refined by Zhang Yu, slightly surprised: "The color is bright, the impurities and purity seem to be much better than before... Is it Level 2 Tianqing sand?"
"Is it just luck? Or is he really progressing fast?"
Ye Xingli continued to observe but quickly discovered that Zhang Yu began to randomly compress the refining ti, and the produced Tianqing sand reverted to a Level 1 standard.
And when the six hours of practice were completely over, after repeated attempts, Zhang Yu managed to compress the refining ti of Tianqing sand to about 15 minutes.
"Compressed the materials to one-tenth, which is 0.003 spirit coins."
"The cost of site and equipnt rental is 0.7 spirit coins for 6 hours, split with Ye Xingli it’s 0.35 spirit coins."
"If I continue to maintain 15 minutes per refinent in the future, I can complete 24 refinents in 6 hours."
Zhang Yu calculated silently: "Considering this, the cost per refinent is roughly compressed to about 0.01758 spirit coins."
"And this still isn’t the limit."
Zhang Yu thought of his Formless Warrior and Deep Cold Warrior.
Just like when working on a construction site, where he uses Formless Warrior and Deep Cold Warrior, he thought artifact refining could be done similarly.
Zhang Yu thought to himself: "With the compression of materials and ti already settled, next ti... I’ll employ Fourfold Thinking to see if I can synchronize the refining of four batches of Tianqing sand simultaneously."
"If successful, not only would the costs go down further, but the efficiency of cultivation can also soar again."
"Besides, after continuously refining Tianqing sand, if I sell part of it to recoup so costs, the expenditure of spirit coins can be lowered further."
Thinking of this, Zhang Yu looked at Ye Xingli and asked, "Senior, if I want to sell so products I made in practice in the future, where would be convenient to sell?"
Ye Xingli thought about the Magnetic Pole True Monarch’s instruction and said directly, "If you trust , just leave it with in the future."
"I have so connections in the Artifact Refining Departnt and can help you sell it."
"But basic refining products don’t fetch a high price; at most, you could recoup so costs."
Zhang Yu nodded quickly and said, "I understand, it’s fine, as long as I can recoup so costs."
After leaving the laboratory, they bid farewell to each other.
And as Ye Xingli watched Zhang Yu’s back as he left, she sent a ssage to the Magnetic Pole True Monarch: "Master, I just left the laboratory with Zhang Yu."
Magnetic Pole True Monarch: "How is Zhang Yu performing?"
Ye Xingli: "His talent in artifact refining seems fine; he refined Level 2 Tianqing sand during the 6 hours."
Ye Xingli: "But his attitude is problematic; he’s just a beginner, yet he likes to randomly alter the quantities and ti."
Ye Xingli briefly described the situation she observed.
Magnetic Pole True Monarch replied: "I understand."
Magnetic Pole True Monarch: "In the future, if he wants to sell his products, temporarily help him consign them."
Magnetic Pole True Monarch: "Regarding the laboratory, you can also split the cost with him."
Upon hearing Magnetic Pole True Monarch instructing her to help Zhang Yu like this, Ye Xingli finally couldn’t suppress her curiosity.
She asked: "Master, is Zhang Yu a student from the Civil Engineering Departnt? His talent in refining isn’t all that outstanding, so why help him so much?"
Magnetic Pole True Monarch: "The Director of the Civil Engineering Departnt wants to transfer his student to the Artifact Refining Departnt."
Magnetic Pole True Monarch: "Although I don’t highly recomnd it, considering our centuries-old relationship, if he insists, we have to help regardless of the loss."
Seeing the ssage from Magnetic Pole True Monarch, Ye Xingli couldn’t help but admire the friendship between the Magnetic Pole True Monarch and Director Gao.
She thought to herself: "Indeed, it’s not Zhang Yu, a Civil Engineering student, that attracted the master’s attention, but Director Gao’s request."
Ye Xingli also found this reasonable; after all, a Civil Engineering student is akin to soone in the Security Departnt, a ’specialized school’ student in Wanfa University, right? With her master’s high standards, how could he be interested?
Probably they’d need to give a red packet before even speaking a word.
"But master and Director Gao... an ancient cultivator’s friendship?"
"Even though the master keeps up with the tis, constantly learning the latest Immortal Path technologies and keeping up with Kunxu trends, ultimately, as an ancient being, the thinking inevitably gets influenced by ancient outdated cultural remnants."
Just as Ye Xingli was pondering, the Magnetic Pole True Monarch sent another ssage.
Magnetic Pole True Monarch: "This matter is currently confidential; even if asked face-to-face by or Director Gao, we’ll deny it."
Magnetic Pole True Monarch: "Rember not to disclose this."
Ye Xingli: "Master, trust , I wouldn’t reveal it even if offered 1,000 spirit coins."
...
anwhile, on the other side, Zhang Yu was on the road heading to the worksite on the 667th floor.
He first looked at the Tianqing sand Level 2 (10/20) on the Yu Shu, and then at another artifact refining skill on the Yu Shu.
Azure Cloud Sash Level 0 (0/1, Azure Sand 2/5 Level)
This Azure Cloud Sash is an artifact blueprint Zhang Yu learned in the Artifact Refining Departnt’s courses, and it’s a kind of magic treasure specifically used to store Azure Sand.
With the injection of mana, it can conduct large-scale spraying and recovery of Azure Sand.
As with Zhang Yu’s initial cultivation technique training, many artifact refining skills require eting specific thresholds to master.
For the refining of Azure Sand, there are requirents in terms of mana and Gang Qi.
The Azure Cloud Sand Sash requires mastering certain Azure Sand refining techniques first.
"Whether it’s a magic treasure or magic remains, aside from requirents of realm, Dao Heart, and mana, there are usually various prerequisite skills in artifact refining."
Zhang Yu thought to himself, "To gradually cultivate oneself to the level of refining one’s physical body into magic remains, besides cultivation, one needs to master nurous prerequisite artifact refining techniques."
"There is still a long way to go."
"However, with so many artifact refining skills, it probably won’t be necessary to perfect every single one in the future. It just needs to be sufficient."
As for more distant goals like having his own Artifact Refining Laboratory or establishing his own production line... Zhang Yu can only dream of these for now.
Familiar with the route, Zhang Yu arrived at the construction site, where several Formless Warriors appeared beside him.
Reaching out, he scattered so Azure Sand onto the Formless Warriors.
The Formless Warriors’ rolling Gang Qi within surged, causing a glimr from the Azure Sand, making the Formless Warriors appear more solid.
Zhang Yu contemplated, "Azure Sand can improve Gang Qi transmission efficiency and reduce consumption speeds, which should enhance my work efficiency."
Thus, Zhang Yu controlled the Formless Warriors to work on the construction site to earn money, while enveloping himself in the fog ford by Formless Cloud Gang, beginning his cultivation of the seventh cultivation technique of the Martial Arts Saint Body.
Several hours passed, and as dawn broke, Zhang Yu calculated today’s wages, musing, "Construction efficiency improved by roughly 5%."
"Not bad, not bad. If the Azure Sand level increases in the future, the efficiency improvent should be greater."
"So even if Senior Sister Ye Xingli’s consignnt sale of Azure Sand isn’t much, I can still use it to increase my inco at the construction site."
Thinking of this, Zhang Yu felt even more motivated.
In the coming days, Zhang Yu would lease the Artifact Refining Laboratory one or two tis a week for practicing artifact refining skills.
The rest of the ti involved attending classes during the day and working on the construction site at night, while simultaneously cultivating the Martial Arts Saint Body technique.
Additionally, he needed to find ti in the Taiqing Realm to study artifact refining courses, absorb mana with 200% quality to enhance his mana quality, and go to Hamr Heart Inn to temper his Dao Heart...
...
Inside the laboratory.
Ye Xingli glanced at the three Formless Warriors, musing, "Such strong thinking ability."
"But is multitasking and producing multiple batches of Azure Sand beneficial to improving artifact refining skills? It’s not about piling up quantities to improve skills."
In Ye Xingli’s view, unless trying to et production targets, focusing on refining one batch of Azure Sand, feeling the materials, steps, timing, heat, mana, Gang Qi, and other details while continuously learning and adjusting, is more effective for skill enhancent.
At that mont, Ye Xingli’s gaze moved sharply towards a Formless Warrior successfully refining Azure Sand.
"Level 3 Azure Sand?"
"Interesting."
Ye Xingli thought, "Although he likes to ss around, Zhang Yu’s talent in artifact refining seems stronger than my previous assessnts."
However, Ye Xingli wasn’t too concerned as she recalled that the first ti she refined Azure Sand, she directly produced Level 5 Azure Sand.
Turning away, Ye Xingli continued interviewing her new Artifact Spirit.
"Were you a graduate of Hehuan University? May I ask what your primary gender is?"
"You are an upper-class student? Sorry, this recruitnt only aims to hire soul cultivators who graduated from the top ten universities."
"Sky Demon University? Welco to join, treat my right hand as your ho in the future."
...
That day, just after leaving the laboratory, Zhang Yu received a ssage from Gongshu Jin.
Looking at the ssage, Zhang Yu’s eyes lit up: "Is the buffet starting now?"
anwhile, Ye Xingli glanced at Zhang Yu and said, "You’re going to the gathering later, right? After all, it’s kind of a victory celebration for the Civil Engineering Departnt."
Zhang Yu nodded, already knowing that this gathering was arranged by Mo Enting, primarily to celebrate the second-place achievent in the interschool league.
Ye Xingli casually remarked, "Let’s go together then, as I’m also attending."
Zhang Yu followed Ye Xingli to the 650th floor of Wanfa University; just as they stepped out of the anti-gravity passage, they saw Gongshu Jin waiting outside.
Seeing Zhang Yu walking with Ye Xingli, Gongshu Jin was surprised.
Compared to the first ti he encountered Ye Xingli last year, this year’s Ye Xingli appeared vastly different in Gongshu Jin’s eyes.
That is, the ranking atop Ye Xingli’s head in the Artifact Refining Departnt had risen from 15th to 8th.
Holding this rank in one of the three major departnts marked Ye Xingli as a top-tier student at Wanfa University in Gongshu Jin’s estimation.
Observing the jovial manner between the two, Gongshu Jin pondered, "When did Zhang Yu beco so friendly with Ye Xingli?"
