"Heavenly Thunder Bamboo, such a strange thing, this door does not have. Senior, my door has always been well-informed, I can instruct the people under the door to investigate the news of this day's thunder bamboo, as soon as there is news of this thing, I will inform the seniors, how? Zi Ling retracted his expression and said solemnly.

"Well, last time I left a transmission note for Fan Jingmei, you can ask her for it, and let me know as soon as you have any news."

After listening to Zi Ling's words, he was inevitably a little disappointed in his heart, but now it was still important to refine the natal magic weapon, and the matter of the Heavenly Thunder Bamboo would be handed over to Miaoyinmen for the time being.

About half an hour later, Yan Bin left the Wanshi House and returned to his cave mansion.

[Ding, the system prompts: The number of Xuanji stones harvested this time is enough for the time being, but it has not yet reached the required amount. 】

'Hold on? Will you still use Xuanji Stone in the future? Yan Bin exclaimed in surprise.

[System: All natal magic weapons refined must use Xuanji Stones, and a large number of Xuanji Stones are required. 】

Yan Bin laughed a little in surprise and accepted this fact.

He meditated on the wooden bed and adjusted his physical and mental state to the best state.

Five days later, he woke up from his meditation, opened his eyes, thought about it, and deduced it in his mind.

He took out the "Cloud Experience" and "Formation Essentials" from the storage bag and looked at them carefully.

In order to refine the complete set of magic circles of the natal magic weapon in one go, he must be cautious, the materials are rare, and he is absolutely not allowed to fail.

Although his refining level and formation level had been fully mastered, that was when his cultivation was not high.

Now that he had broken through the Jindan stage, the difficulty of the magic weapons and formations he had refined had deepened a lot.

Without full certainty, he will not use his real name magic weapon as a practice.

Before refining the natal magic weapon, you must be proficient in the difficult refining techniques, and be proficient in using the knowledge of the formation and the depiction of the talisman technique.

Therefore, he planned to spend some time refining his refining level to a new level, and then refine the natal magic weapon.

It took him two months to study both books thoroughly.

Then, he took out a lot of talisman materials from the storage bag.

The talisman of the intermediate spell uses some rare animal skins as raw materials, which can not only increase the power of the talisman, but also increase the success rate to a certain extent.

He had already hoarded a large amount of demon beast materials as early as the time of the knot, preparing for the refining of the natal magic weapon this time.

He first practiced with inferior demon animal skins, and after his skills were improved, he would use the cherished animal skins to refine special talismans.

Of course, judging from his cultivation in the Jindan period, the power of these talismans is very different from that of magic weapons, and he will throw them into the storage bag to eat ashes after practicing.

In this way, two years passed, and the refining power of the intermediate talisman gradually changed from two percent at the beginning to five or six percent.

However, refining the intermediate talismans was time-consuming and laborious, and it took two years to refine more than 20 talismans.

After he mastered the technique, another three years passed.

A total of more than fifty intermediate runes were refined, and with this batch of runes, he could harvest a large amount of spirit stones.

Then he set out to refine the high-grade magic weapon, due to his talent for formation and refining.

He is very familiar with the refining of high-grade magic weapons, and the success rate of refining is quite high.

After another ten years, he had refined more than 20 high-grade magic weapons, and the techniques of refining magic weapons had been perfected.

On this day, after refining a high-grade magic weapon, he took out a bottle of Tranquility Pill from the storage bag, stuffed a few into his mouth, and settled on the wooden bed.

Ten days later, he opened his eyes with a bright look, and it was obvious that he was back to his best.

Then he took out two pieces of Gengjing from the storage bag, and a fist-sized Xuanji Stone, and floated in front of him.

He solemnly pinched a trick, and the fluorescent flow on his face, and a layer of red light gradually emerged, as the red light became more and more intense.

Suddenly, he opened his mouth violently, and a slender red Dan fire blurted out, spraying on the Gengjing and Xuanji Stone in front of him.

Danhuo consumes a lot of spiritual power, but fortunately he has been prepared for this.

At the same time as releasing the Danhuo, he grabbed this golden and red medium-grade spirit stone with both hands and began to absorb the aura in it.

A few days passed, and the surface of the heptylene and Xuanji stone melted, oozing dense small liquid beads.

After half a month like this, the two stones were finally removed from impurities and refined into a golden, black viscous liquid.

He looked at the two lumps of liquid without sadness or joy, and then pinched the magic trick, and his fingers kept flicking.

Then, the two masses of liquid gradually fused together, spinning and deforming.

Half a year has passed in the blink of an eye, and the metal solution floating in front of Yan Bin's eyes has slowly taken the prototype of the array disc and the array flag, with a total of square array plates and eighty-one array flags.

After a little rest, he pinched the trick, flicked his fingers, and drew a magic circle in the air, one by one, circles of runes slowly condensed in the air.

The runes of this magic circle are extremely complex, and the dense thousands of rune lines are intertwined in an orderly manner, and gradually the prototype of a magic circle is impressively presented in the air.

Such a complex magic circle consumed a lot of his spiritual power, and he couldn't make the slightest mistake, so be extremely careful.

Two years had passed, and beads of sweat were oozing from his face, his closed eyes were turning rapidly, and his face was slightly pale.

On this day, his flicking fingers finally picked up, and a character erupted from his mouth, "Receive." ”

The magic circle in the air bounced violently, and suddenly it turned into a precision magic circle the size of a mirror, and it kept spinning in the sky above the array disk.

"P.S." A cold word. Then, the circle fell on top of the array and seeped into the array little by little.

The process of inlaying the runes of the circle on the array plate is very slow. The runes must be embedded in the array disk half an inch deep in order to complete the refining of the array disk.

The inlay is carved little by little along the runes with Danhuo.

He closed his eyes and unhurriedly unleashed his powerful divine sense, his fingers slowly moving to control the Danhuo to slowly carve.

Year after year of monotonous refining, refining, and refining, he was bent on refining the natal magic weapon successfully, and time passed unconsciously.

After a long time, he naturally had no distractions and was single-minded. When the spiritual power is lacking, he randomly takes out a medium-grade spirit stone and absorbs it.

In this way, ten years passed, and the gate of the cave was tightly closed and there was no movement.

Twenty years have passed, and nothing has changed in the formation arranged by the cave mansion.

Thirty years have passed, and the paths around the cave are covered with fallen leaves.

Time passes, and time flies.

One day forty-five years later, Yan Bin woke up from his meditation and slowly opened his eyes.

His natal magic weapon, the array plate and array flag of the Yin and Yang Great Five Elements Formation, had been successfully refined thirty years ago.
