Chapter 136

A few minutes later,

A light that was invisible even to spiritual sense scanning shone down.

The meters-high and wide Taiqing Divine Iron blurred, actually penetrated the window and the roof, and disappeared silently.

"One month..."

Jiang Ding muttered to himself, suppressing his impatient mood, sat on the bed, and closed his eyes to cultivate.

Regarding the sword of his Dao foundation, he had also prepared a second plan.

If his Taiqing Divine Iron did not return.

Then he would believe that the Immortal Sect created by the countless sacrifices of the sages of past generations had corrupted and deteriorated, and even the Central Formation Spirit Computer, which served as the last line of defense, had fallen, becoming a tool for aristocratic families and high-tier cultivators, no longer the Immortal Sect of the citizens.

……

"Starting today, we begin the refining of magic tools."

Wu Chengzhong beckoned, and a cyan flying sword flew over from not far away: "This is an Immortal Sect foreign trade flying sword, a mid-grade magic tool, the Qingyun Sword. It uses Breaking-Law Steel as the base material, mixed with dozens of types of spiritual gold and engraved with formation patterns using Tier 1 spiritual ore Qingling Iron. Its special effects are speed and sharpness."

That's right, mid-grade magic tools still don't use all spiritual materials; it's just that the gold liquid in the melting pool has become pure spiritual gold, no longer the small amount of blended spiritual gold added to a large amount of gold liquid like in semi-magic tools.

"By purely adopting Immortal Sect technology, the material cost can be reduced to one-fifth of that in the outer cultivation world."

"The selling price is nine times the Immortal Sect's cost, and even then, it is still lower than the material cost plus the artifact refiner's labor cost for outer-world cultivators."

"If free trade were possible, it would be completely sufficient to destroy the mid-to-low-tier artifact refining industry of outer-world cultivators."

Wu Chengzhong had a look of regret on his face.

"Unfortunately, except for the initial period, many outer-world sects have imposed high tariffs on Immortal Sect foreign trade magic tools; currently, only parts of the Five Elements Heaven Sect's territory and the Immortal Sect's minor realms can trade freely."

Immediately after, he demonstrated it on the operating table.

The spiritual gold liquid in the melting pool turned into threads, and under his control, it traveled through the semi-solid Breaking-Law Steel sword, as if weaving and dancing, bit by bit weaving complex and efficient formation patterns.

More than an hour later, a cyan-light-flashing flying sword was engraved, cooled down, completely solidified from semi-solid, revealing a cyan-light-flashing sword body, dropped onto the assembly line, and tested as qualified.

"That's how it is."

Wu Chengzhong stood up and said with a relaxed face: "Just skillfully apply the knowledge I have given you. This time, I don't force a one-time success; it's just to go through such a process, to have an understanding, and to use it as a basis for choosing a career in the future."

Over the past two weeks, he had taught everything he could, and the rest was up to individual understanding.

"Begin."

"Yes, Engineer Wu."

Jiang Ding, Hua Bing, and the three of them said in unison.

Jiang Ding was assigned to a room, sat down, closed his eyes to rest for a long time, and adjusted his internal power to the most lively state.

The Tier 1 Qingyun Sword has four formations: the Tier 1 Spirit-Gathering Formation, the Tier 1 Floating Formation, the Tier 1 Gale Formation, and the Tier 1 Sharp Metal Formation. They are all very common basic formations, but because they are engraved with spiritual gold and are three-dimensional stereoscopic formations, their power and strength exceed those of talisman swords from the start.

In terms of complexity, they are far inferior to the Tier 1 Great Sun Spirit-Gathering Formation and the Tier 1 Special Sharp Metal Formation.

Having cultivated the "Great Sun Sword-Seeding and Sword-Refining Method" for a long time, he was extremely familiar with these four formations and still had some confidence.

Inputting internal power, his perspective became microscopic.

This time, the Qingyun Sword body in his perspective was not like the heavy machine gun barrel that stood like a mountain pillar, but a lake, a lake in the shape of a long river, with the lake water cyan and hazy, rolling from time to time.

Jiang Ding took a deep breath, manipulated a wisp of spiritual gold thread to crash into the cyan-light metal lake from the sky, and starting from the center of the lake, engraved the formation patterns bit by bit from the surface to the inside.

"Very difficult..."

Jiang Ding felt huge resistance as soon as he started; the toughness of the cyan-light sword's semi-solid body meant that every step of traveling through the semi-solid Breaking-Law Steel liquid consumed a large amount of soul power, and he felt a sense of fatigue after only a few steps.

Only spiritual sense can precisely guide the spiritual gold thread to travel through the Breaking-Law Steel liquid.

Besides this, in the microscopic perspective, the Breaking-Law Steel liquid is not static, but has constant fluctuations like sea waves, making it difficult to precisely engrave the formation diagram.

This is also the reason why, even within the Immortal Sect, very few mortals become Tier 1 artifact refiners.

"Can predict."

Jiang Ding did not give up; he carefully observed the movement trajectory of the Breaking-Law Steel liquid, manipulated the spiritual gold thread to follow its movement, and suddenly guided the spiritual gold thread to solidify when it moved to the formation pattern engraving location.

Just like this, he expanded the trajectory of the three-dimensional formation pattern bit by bit; his spirit became more and more fatigued under high attention, and many times he could only rely on guessing to determine the position of the spiritual gold thread.

The formation patterns gradually formed a net, seeping into the interior of the Breaking-Law Steel.

When he was halfway through engraving, Jiang Ding's microscopic perspective was already blurred, and he could only rely on a trace of instinct in the dark to make a general judgment.

Time passed, he didn't know how long.

After the last stroke of the spiritual gold thread formation pattern was drawn, his eyes went black, and it took several minutes for him to recover, panting heavily.

Ding!

The Qingyun Sword solidified and formed, falling into the assembly line; one of the three green lights lit up, and the remaining two were red lights.

"Barely reached the level of a low-grade magic tool."

Wu Chengzhong clicked his tongue in wonder: "I didn't expect that the students in the mid-to-late Qi Condensation stage didn't refine a magic tool, but you actually did; it seems you have great talent in the artifact refining profession."

This kind of defective product cannot be put on the market and must be destroyed.

"Jiang Ding, not bad."

Hua Bing and Wu Tianli congratulated him.

"Nothing, just luck."

Jiang Ding shook his head.

This is a fact; many times his spirit was blurred, and he could only rely on guessing the position of the formation patterns, which indeed led to many mistakes in many places, resulting in large areas of unqualified work.

'However, if I were to use the flying sword I have refined for a long time as ink, I would definitely succeed!'

A powerful confidence grew in Jiang Ding's heart.

"As expected of the fierce person who beat up my son at will in the actual combat exam; your cultivation talent and artifact refining talent are both very strong."

Wu Chengzhong looked at Jiang Ding with regret, making the latter touch his head in embarrassment: "Alright, your winter vacation internship ends today. I wish you all can get into the cultivation department of your ideal university in the college entrance examination."

"Thank you, Teacher Wu!"

Jiang Ding and the three of them also stood up to thank him.

Over the past half month, Wu Chengzhong's lectures were interesting, humorous, and easy to understand, giving them a lot of understanding of the artifact refining industry.

After going to school to cultivate for several more hours, Jiang Ding returned home with two express boxes in his hands.

Opening the first large one in the room, it was a gray stone box, and there were faint formation patterns on the box surface.

【Tier 1 Spirit-Sealing Box】

【Function: Seals and isolates spiritual power; can be used for storage, and can also be used to isolate dangerous items, spiritual sense peeping, etc. When not subjected to violent destruction, it also has a good isolation effect on the spiritual sense of Foundation Establishment and Golden Core cultivators.】

This was the box he ordered three days ago to store the two storage bags, preventing the black-robed person from leaving behind hidden traps.

He opened the second, smaller square box.

Inside was a palm-sized mechanical arm that could be installed on a drone; the price was also very cheap, only one thousand mortal coins.

After confirming the two items, Jiang Ding's figure disappeared.
