Yuan Ming didn't feel that time had passed so long.

He didn't know how many times he stood up and sat down before he returned and shook his head at him as soon as he saw him.

Yuan Ming's heart sank suddenly.

"Except for the master, there are only three elders above the foundation building stage of our Fire Refining Hall, and they are all in the retreat refining tool right now, and none of them have come out, so no one can help you." Amuhe said helplessly.

"Then what should I do, I can't watch the spiritual power of the Qingyu Sword fall silent and become a mortal, right?" Yuan Ming frowned.

"You can only try your luck and wait and see if the master can return in three days." Amuhe sighed and said helplessly.

Yuan Ming had no choice but to thank Amuhe and left in a hurry.

He first went to the courtyard of the Lord of the Three Caves, but he still couldn't see anyone, so he had to go back to his residence.

The moment he pushed the door in, he saw Huo Yu'er lying on the table in front of the window, but after hearing Yuan Ming's movement, Huo Yu'er immediately got up.

Yuan Ming looked out the window and saw that on the horizontal branches of the pine trees outside, the sunset shadow seemed to be basking in the sun.

The silver cat Xiying noticed that Yuan Ming was looking at her, and ignored Yuan Ming and turned over to continue.

Yuan Ming saw that Xiying was like this, and he wanted to open his mouth and swallowed back, but he just came to the table and sat down with the sword box, thinking with a sad face.

The gluttonous man came at him flatteringly, and he didn't have time to pay attention.

Counting from yesterday, almost a day has passed.

There were still two days left in the retention period of the Spirit Box, and he had to complete the spirit engraving within these two days.

But he had a hunch in his heart that there was a high probability that the master of the three caves would not come back in the near future.

"Otherwise, let's go to Fang Market again?" Yuan Ming hesitated whether to find the refiner there to help him, but when he calculated the distance, it was too late.

"Show me what's in the spirit box." At this time, the curious voice of the silver cat sounded in his knowledge.

Yuan Ming subconsciously raised his head, and saw that the silver cat sunset shadow had come to his window, and Huo Yu'er didn't know when, falling to the ground and rolling.

"This is a sword that the Lord of the Three Caves helped me refine. If you don't have the foundation building period to cultivate, you must not be able to infuse the magic weapon with spirits? He couldn't help but ask.

"Naturally...... However, nothing is absolute. When the silver cat heard him ask this question, he already understood why Yuan Ming's face was sad.

"Do you have a way?" Yuan Ming's eyes lit up, and he was immediately overjoyed.

"In the cultivation of the law, there are talismans who are proficient in the way of talismans, and there are also formation masters who are proficient in the magic circle. They are deeply cultivated in the talisman array, and they can use the talisman or array to exert unique abilities that other monks do not have. Among them, the array master created a rune magic circle called the 'Spirit Gathering Array', which can replace the refiner and infuse the magic weapon with spirits. Silvercat Sunset explained.

"Isn't you a soul cultivator, isn't you still a formation master?" When Yuan Ming heard this, he was surprised.

"I'm not a formation master, but I know the Spirit Gathering Array." Sunset gave him a blank look and said.

"You just know? Still able to draw or ...... How can you help me? "Yuan Ming didn't know how the Spirit Gathering Array was used.

"I'm not a formation master, so I don't know how to draw. Besides, the Spirit Gathering Circle is not a talisman, and it cannot be drawn on rune paper and can be used. Sunset said.

"Forget it, in two days, I can't find a way to fill the spirit, and my herring sword will be useless. You can't help either. Yuan Ming said.

"What? Is there something I can't do? …… In fact, you have seen the Spirit Gathering Circle, which is on that foggy island, on the casting furnace of the Black Wood Master you found, but you have no eyes and no beads, so you didn't take it away. Sunset Shadow airway.

How did it know that Yuan Ming was not illiterate, but his ability was limited at that time, otherwise he would have put away the stove a long time ago.

"At that time, there seemed to be other people on the island, and I'm afraid that the casting furnace was long gone." Yuan Ming was happy at first, and then worried.

"The casting furnace is still there." The silver cat Sunset Shadow immediately gave him a reassurance.

"Really?" Yuan Ming was overjoyed when he heard this.

The silver cat Sunset Shadow snorted lightly and disdained to answer.

"Thank you!" Yuan Ming was overjoyed, picked up the sword box and ran out.

"Next time, I'll have to find something you don't understand to test you." Walking to the door, Yuan Ming remembered something again and added.

"Accompanied!" The silver cat replied.

When Yuan Ming passed by Huo Yu'er, the latter immediately jumped up to his shoulder along his calf.

The silver cat Sunset looked at his departing figure, and there was a smile in his eyes, and after a little hesitation, its figure jumped down from the pine tree and quickly disappeared.

……

Half a day later, on the island of fog.

On a steep mountain wall, patches of moss grow, and green and black vines hang down, obscuring a hidden semicircular hole.

In the sky outside the cave, a black raven spread its wings and flew around, hovering for a long time before slowly falling.

It landed on a stone outside, and pecked with its head down, as if eating, but its dark eyes rolled and looked around secretly.

Seeing that everything around him was stable and nothing unusual, the raven jumped and turned around, spread its wings and plunged headlong into the hole in the vine-covered hole in the mountain wall, and disappeared.

Ten miles away in a hidden mountain forest, Yuan Ming sat quietly in the dense canopy of a towering ancient tree, checking the situation in the cave through the sight of the soul crow.

"It's okay, it's really still there." The moment he saw the casting furnace, he couldn't help but breathe a sigh of relief.

Then, he got up and used his wind agility to leap off the canopy and hurried towards it.

The figure of the silver cat appeared not far away, and followed closely.

After a while, Yuan Ming had already come to the cave with the fire gluttony on his shoulder.

The moment he saw the casting furnace, Yuan Ming immediately waved his sleeves and rolled up a strong gust of wind, blowing away all the dust on the casting furnace, and then immediately leaned over to find the spirit gathering array in Sunset's mouth.

He walked around the furnace, but he didn't see any magic circles engraved on it.

"How could it not be?" As he pondered, he leaned down and crawled under the casting furnace.

At the bottom of the casting furnace, there was also only a flame pattern, and Yuan Ming didn't see anything special.

"Inside the hearth." At this time, the voice of the silver cat sunset sounded in Yuan Ming's sea of knowledge at the right time.

Yuan Ming raised his head suddenly, and his head slammed into the casting furnace with a "bang".

When he withdrew from under the furnace, he saw that the silver cat Sunset was already lying on the furnace, and he watched him scrambled.

"If you don't warn me, I can find it." Yuan Ming said.

"Even if you find it, do you know how to use the Spirit Gathering Circle?" The silver cat Sunset glanced at him with mockery in her expression.

Yuan Ming was also stunned for a moment, and then asked, "Do you know?" ”

"Of course, open the hearth seal and look at the bottom." Sunset instructed.

Yuan Ming hurriedly responded, and opened the hearth to seal the door according to his words, and before he could see clearly, Huo Yu'er took a step forward and got into his arm, ran around inside, and then ran out again.

Only then did Yuan Ming see that the bottom of the furnace was not a smooth flat plate, but a rune array with quite complicated lines was engraved.

At first glance, he felt that one of the runes was a little familiar, looking a bit like the transformation of a flame rune, and there were five runes with complex lines around it, which he couldn't recognize.

These five runes are centered on the flame script, and the surrounding five runes are linked to each other to form a whole, supporting each other to form a stable framework structure.

"Is this the circle?" Yuan Ming muttered to himself.

"This Spirit Gathering Circle is very concise, although it is exquisitely conceived, its power is limited, and at best, it can only assist in the completion of the infusion of medium-grade magic weapons, and it can be regarded as the most rubbish one." Sunset said.

"Where do you see the simplicity?" Yuan Ming only felt that the lines were already very complicated.

"This Spirit Gathering Array is centered on the flame runes, and it is also built with the five Spirit Gathering Runes as the fulcrum, and there are no superfluous runes and complicated lines in it, so the power is limited, but it also avoids the loss of spiritual power, which is not concise?" Hearing this, the voice sounded in Yuan Ming's sea of knowledge.

"In this way, the rune array is not a simple stacking combination of runes, and if it is not properly matched, it will be suspected of getting twice the result with half the effort?" Yuan Ming thought for a moment and asked.

"Naturally, it can't be simply stacked, in fact, this compatibility is quite difficult to control. It is necessary not only to consider the mutual growth and restraint of the rune attributes, but also to consider whether the lines between the runes are smooth and whether they will cause mutual interference. Otherwise, all the rune masters can become formation masters. Sunset said.

"I see. So how to use this Spirit Gathering Circle? Yuan Ming was stunned, and then asked.

"See the grooves in the centers of the five runes around you?" Sunset asked.

"See, what's that for?" Yuan Ming wondered.

"That's for placing spirit stones and absorbing spiritual power, and if your own mana is not enough, you need to fill it with the spiritual power of spirit stones. The flame rune in the middle is the key to transformation, and it controls the transmission of spiritual power into the herring sword. Sunset replied.

When Yuan Ming heard this, he immediately turned his wrist and took out five lower-grade spirit stones.

"Is that okay?" Yuan Ming asked humbly.

"Enough for your sword." Sunset glanced at it and bowed.

Yuan Ming immediately carefully placed the five spirit stones into the hearth one by one.

"Open the Spirit Chest." Silver Cat Sunset Shadow commanded.

Because Yuan Ming really didn't understand the Spirit Gathering Array, he didn't dare to slack off, so he simply acted honestly as the executor.

He opened the Yunling Sword Box as he said, and the Qingyu Sword immediately revealed its true face, and wisps of cold aura spread out of it, and Huo Yu'er immediately showed a look of disgust and ran aside.

"The basic attribute of the sword body is cold, what runes are you going to engrave?" Sunset asked.

Regarding this point, Yuan Ming had already thought about it on the way here, but he was a little hesitant when he spoke at this time.
