“The Invisible Needle requires attributeless ores as refining materials, supplemented by special array patterns and refining methods, to create an invisible, shadowless, silent and invisible needle.

Therefore, the invisible needle does not require a specific kind of ore. There can be both lower-grade yellow-level invisible needles and invisible needles that surpass the yellow level. Of course, the power between the two is naturally incomparable.

What I am refining now is the lowest-level invisible needle, which can even be refined with ordinary fire. Although its power is relatively weak and it is simple to refine, it is still a high-grade magic weapon after all."

Yi Ming came to the center of the refining room, lit three furnaces, then sat cross-legged on the ground and continued to review the refining steps of "Invisible Needle".

After a while, the three furnaces emitted bursts of red light, and he threw the three pieces of material into them and smelted them with the fire.

Throwing the ore away, Yi Ming came to the other side of the refining room, looked at the various molds piled in the corner, flipped through them casually, and picked out a set of suitable needle-shaped molds.

There are only nine pinholes on the one-foot-square mold.

He poured a furnace of molten iron into the molten iron. While stirring it, Yi Ming began to make hand seals in the furnace to promote their full fusion. After a while, he poured the liquid melted from the soft phase stone into the furnace.

The correct content is in %六九% book'bar!

Um……

In the end, the mold is still a mold, as if there is nothing inside, and the molten iron that had just been filled in has completely "disappeared".

Not long after we sat down in the VIP room, Li Qianzhang pushed the door open and walked in.

With a surge of true Qi, Yi Ming wrapped a ball of molten iron with his true Qi and spread it into the mold.

Feeling the vague and slightly obscure aura, Li Qianzhang's eyes flickered. Although the material did not seem to be very powerful, the aura was really obscure. It was definitely a top-notch weapon for sneak attacks, assassinations, and comebacks!

With a slight smile, Yi Ming stretched out his hand and nine invisible three-inch long needles flew into his hand.

Li Qianzhang originally thought that Yi Ming wanted him to sit down, but when he suddenly glanced at Yi Ming's "meaningful" smile, his heart skipped a beat.

He stretched out his hand and made a gesture of invitation towards the empty table.

He collected a total of eighteen invisible needles.

…

Early the next morning, after Yi Ming finished refining, he practiced and recovered for a while before walking out of the Li family's refining room.

"Daoyou Zhang."

"Friend Li." Yi Ming smiled slightly, but this smile was not flattering given his ugly face.

"Um?"

Eighty spirit stones for one needle, four invisible needles, that's three hundred and twenty spirit stones! "With a skill in hand, you really don't have to be afraid to travel the world."

It was unexpectedly low, apparently because the quality of the technique he practiced was not high, which resulted in his low sensing ability, several levels lower than his own.

He and Xiao Shitou and the others made an appointment to set off for Linluo City early this morning, because he originally wanted to go back to Linluo City to refine the weapon again, but he didn't expect that he would have refined the magic weapon in Hualin City.

Because in Yi Ming's eyes, although these invisible needles are invisible, the Qi is very obvious, as if visible.

When he was serious, the invisible needle that emitted bursts of energy could naturally not be hidden from his perception.

“It’s not much different. Fortunately, I didn’t refine a set of needles. The main killing power of the invisible needle is still the true energy attached to the needle, and it doesn’t rely on physical damage.

Besides, I only have this much material, and I will probably only refine it two or three times, so it's okay if it's a little troublesome."

Touching the invisible needle in his hand and feeling the aura of the invisible needle that could only be felt by practicing the "Invisible Needle" technique, Yi Ming was very satisfied.

"How are you, Immortal Master?" A mortal waiter stepped forward quickly and bowed respectfully.

Yi Ming's eyes flickered when he heard this. Li Qianzhang's performance was also beyond his expectations.

After all, it was a high-grade material. Even if it was smelted with ordinary fire, it would take a long time. After half a day, three fist-sized pieces of ore were turned into molten iron, and their volume was reduced by one third.

"hiss!"

"Are you satisfied, Brother Li?"

"Of course I am satisfied." Li Qianzhang said with a smile, "I wonder what this magic weapon is called? Fellow Daoist Zhang, can you sell me a few?"

There are also six invisible needles. Yi Ming omitted a dozen array patterns when they were finally formed. As a result, although these six invisible needles are invisible and traceless, they cannot hide their own aura and are easily discovered and blocked.

"Please move aside, Master. I'll go and ask Manager Li to come." The waiter's eyes lit up. It seemed like business was coming.

"Well……"

However, Li Qianzhang naturally looked at Yi Ming eagerly. He certainly didn't care about Yi Ming's appearance. Li Qianzhang had seen many cultivators who were uglier than him.

Li Qianzhang walked up to the round table and carefully picked up an invisible needle. He circulated his Qi in the needle and thought for a moment before saying, "This treasure is indeed mysterious, but it's a pity that it's only a lower-grade yellow-level one with limited power. I'm willing to buy it for eighty spirit stones. What do you think?"

It was still early, so it wouldn't take much time to sell the invisible needle to the Li family. When he arrived at the door of the VIP room, Yi Ming carefully sensed it for a moment, but he didn't sense any ambush such as magic traps.

Another half hour passed, and the entire furnace of molten iron turned light red under the adjustment of Yi Ming's true qi and array hand seals.

After taking a deep breath, Yi Ming once again mobilized his true energy, and special array patterns were driven into the mold. The light red iron needles cooled rapidly, and the red color became lighter and lighter until it was invisible.

"The aura is obscure and hard to detect, appearing and disappearing from time to time. It is indeed a good magic weapon!" Li Qianzhang praised.

Hmm? Zhang Daoyou? Oh, yes, my name is Zhang Daqian now...

It is worthy of being a blue-quality martial art. Even the lowest-level invisible needle cannot be sensed by a cultivator in the Qi Refining Stage.

"Not bad." Yi Ming nodded. Now that he had the eighteen invisible needles as a foundation, he was much more resilient. He was not afraid that the Li family would rob him and turn against him.

"Well, what about you guys, Manager Li?"

Li Qianzhang's reaction once again surprised Yi Ming. It seemed that he thought that these six invisible needles were all that he had refined? "This treasure is called the invisible needle." Yi Ming nodded and said, then shook his head, "It is not easy for a cultivator to practice, Zhang left two for us."

He continued to hammer the array handprints into the molten iron. The originally bright red color of the molten iron was gradually fading, but the temperature was rising higher and higher. Yi Ming was three feet away from the furnace, but he could still feel the waves of heat coming.

"Is there something weird about this table?"

"Okay." Yi Ming nodded.

Strike while the iron is hot, Yi Ming refined the remaining molten iron for another furnace and a half.

Yi Ming's mind was racing, but he agreed cheerfully, "Of course."

…

After selling four inferior invisible needles and exchanging them for more than three hundred spirit stones, Li Qianzhang personally sent Yi Ming to the door of the store.

"If fellow Daoist is interested in refining this invisible needle again, the Li family welcomes you at any time."
