In Chen Xian's inheritance memory, the immortal rune and the ancestral dragon could not be destroyed, and as for whether the saint could destroy it, he didn't know.

That is to say, the decomposition of the innate immortal aura into the immortal rune is already the extreme, even if Chen Xian squandered the sun true fire in the oolong sword, these immortal runes will not change again.

"It seems that the innate immortal aura is not an ordinary material, and it cannot be used in an ordinary way. Looking at the immortal rune that shimmered in the furnace, Chen Xian was amazed.

"In this case, if you use these immortal runes to turn into the last seven layers of the scabbard, in this way, the quality of the scabbard is definitely beyond imagination!"

Chen Xian's eyes kept flashing with spiritual light, and his mind began to run rapidly, thinking about the feasibility of using these 907,200 innate immortal runes to construct the last seven layers of the sword scabbard.

After meditating for three days, Chen Xian repeatedly calculated, and finally perfected his idea, and cultivated all the immortal yuan he consumed, adjusting his state to the peak.

However, Chen Xian pinched his fingers and found that this was not the best time to refine the sword scabbard, so he did not act, but closed his eyes, silently used Xuangong, recuperated his energy, and waited for the best time.

I don't know how long it has been, Chen Xian, who has been meditating with his eyes closed, suddenly moved in his heart, and his closed eyes opened suddenly.

"Boom!" suddenly came a dull thunder above the nine heavens.

"At the beginning of the spring thunder, when the trees recover. Okay, this is the best time to refine the wood attribute magic weapon!" Chen Xian's heart moved, his hands flew up, and countless mysterious handprints were formed.

As Chen Xian's handprint changed, the wind in the furnace burst into flames, and the violent flames swept the more than 900,000 immortal runes aside, slowly reducing the firepower, but it kept a temperature that would not let them no longer condense into one.

After the Immortal Rune was moved aside, Chen Xian's handprint changed again, and there was a buzzing sound in the refining furnace, and the air couldn't help but squeeze towards the middle, gathering together the materials that had been vaporized to the point that they couldn't be seen, turning into a white-green air mass the size of a basketball.

Chen Xian's mind moved, and his handprint changed again, and the white-green air mass in the furnace was pulled by an invisible force, and it changed for a while, and it was shaped into the image of a sword scabbard.

Chen Xian's heart moved, and he pinched a fire trick to isolate the temperature around the scabbard, so that the scabbard cooled and formed, and transformed from gas to solid.

Before the scabbard was completely solidified, Chen Xian's hands convulsed like crazy, and he shot out countless runes, forming layers of prohibitions and imprinting them on the scabbard.

The runes fell onto the unformed scabbard and turned into marks like dragon scales and cloud patterns, which were both beautiful and non-slip.

For about half an hour, the speed of Chen Xian's hands slowed down, and his forehead looked a little tired.

This is also the reason why non-Da Luo Jin Immortal can't refine the acquired treasure, because if it's not Da Luo Jin Immortal, there is no way to lay enough prohibitions before the magic weapon is formed. And Chen Xian originally wanted to use a large number of high-quality materials and the characteristics of the innate spiritual root to extend the formation time of the magic weapon and lay enough prohibitions, so as to refine the acquired treasure.

"Huh......" Chen Xian exhaled deeply, his hands also stopped sealing, his eyes closed slightly, and his eyes looked at the white-green scabbard in the furnace without blinking.

For half an hour, Chen Xian didn't know how many runes were put on the scabbard, at least millions, and a total of thirty-six layers of prohibitions, layer upon layer, perfectly integrated into the scabbard.

With the thirty-six prohibitions, this scabbard will be able to become the top grade in the acquired spirit treasure immediately, but there is still a long way to go from the acquired treasure that Chen Xian expected.

However, Chen Xian was not disappointed, after all, before the scabbard was completed, he still had 902,000 immortal runes, and the seventh-layer innate divine forbidden had not hit the scabbard.

Thirty-six plus seven is equal to forty-three, forty-three layers of prohibition, has entered the flow of the treasure, and there are seven innate divine prohibitions, and the quality is comparable to the top acquired treasure.

Of course, the premise is that Chen Xian can integrate this sevenfold innate divine prohibition into the scabbard and become one of the prohibitions.

"Success or failure in one fell swoop!" After taking a moment of respite, Chen Xian's eyes widened, and with a movement of his handprint, he pulled out an immortal rune with the most dim color, and slowly fell towards the scabbard.

This innate rune is the first immortal rune that appears when the innate immortal aura decomposed by the first layer of the forbidden innate magic weapon of an unknown innate magic weapon, and it can be said that it is the worst of the nine hundred and seventy-seven thousand two hundred immortal runes.

Under Chen Xian's careful control, the immortal rune slowly but firmly landed on the scabbard.

......When the immortal rune was about to fall on the scabbard, the blue light was very large, resisting Chen Xian's traction, unwilling to fall on the scabbard, like a proud phoenix, unwilling to fall on the rotten wood outside the sycamore, or an immortal, unwilling to fall into the mortal dust.

"Sure enough, there was resistance!" This situation had already been expected by Chen Xian, and he was not surprised, his hands were pressed weakly, and the immortal rune fell into the scabbard with a swoop as if it had encountered a heavy blow, and it was deeply clamped in.

Although the immortal rune was smashed into the scabbard, it trembled endlessly, still trying to struggle out. At the same time, the 129,599 runes of the same origin were in full bloom, and a huge pulling force was generated, and they wanted to pull that rune back.

"How can it be so easy!" Chen Xian sneered, and with a movement of his heart, thirty-six prohibitions flashed on the scabbard at the same time, imprisoning the immortal rune in the scabbard, making it impossible to get out.

"Since you are so affectionate like the sea, then you might as well go in and accompany it!" Seeing that the thirty-six seals and prohibitions he had placed on the scabbard before could easily handle the immortal rune and suppress the traction of the remaining 129,599 immortal runes, Chen Xian was overjoyed, and after laughing, he slapped the 129,599 immortal runes into the scabbard at once.

"Hum ......" 129,599 and 129,600, it seems that there is only one "one", but this "one" is the key to whether these immortal runes can become one yuan, whether they can become a congenital divine forbidden, after the 129,599 immortal runes entered the scabbard, the previous immortal rune merged, and after making up the number of one yuan, the power soared, turning into a green dragon, setting off a storm in the scabbard, to break away from the scabbard, leave this small pool, and the dragon returned to the sea.

"Seal, town, lock, trap, forbidden, closed, fixed, trapped, absolute, closed, bound, tethered, imprisoned, fixed, stopped, pressed, solid, fell, bitten, sucked, swallowed, contained, devoured, entangled, wrapped, sticky, stained, pasted, blocked, separated, detained, trapped, trapped, connected, climbed, attached!

Chen Xian shouted, his hands were linked, and the thirty-six prohibitions on the scabbard were smooth and large, some were blocked, some were suppressed, some were entangled, some were bitten, and some were adsorbed, trapping the innate god who had turned into a green dragon, and slowly integrated into the scabbard, and the thirty-six layers of prohibitions were connected into a whole, entangled with each other, and it was difficult to solve.

About a quarter of an hour later, the four legs of the innate god forbidden to turn into a green dragon fell into the four prohibitions of biting, sucking, swallowing, and devouring, and the dragon body was stuck by the three major prohibitions of sticking, dipping, and sticking, and it was surrounded by the prohibitions of trapping, trapping, absolute, binding, tethering, etc., plus the prohibition entanglement such as winding, winding, climbing, and attaching, sealing, suppression, and other prohibitions and suppression, no longer struggling - and unable to struggle, and gave up resistance as if resigned to fate, and obediently became a layer of prohibition on the scabbard. And with the addition of this innate divine forbidden that runs through the thirty-six prohibitions, the power of the thirty-six prohibitions has increased dramatically, making Chen Xian more and more confident in his plan to build an innate divine forbidden with the seven immortal runes as the scabbard.

"Hey, in my hands, it's the tiger that has to lie on my stomach, and the dragon has to coil it for me!" Chen Xian looked up to the sky and howled for a while, then turned his gaze to the furnace and continued to work hard.

This time, Chen Xian chose the weakest 129,600 immortal runes, which seemed to be also transformed by the innate immortal spiritual light forbidden by the first layer of a certain wood attribute innate magic weapon, but it was stronger than the previous immortal spirit runes, and it was obviously a high-grade magic weapon left.

But these are not important, with a wave of Chen Xian's big hand, these 129,600 immortal runes were smashed into the scabbard by him, and then under the thirty-six prohibitions that strengthened the strength, after struggling for four or five minutes, he obediently complied and became the thirty-eighth layer of the scabbard.

Chen Xian thought that the next thing would be smooth, but he didn't want it to happen unexpectedly, but when he entered the Immortal Rune for the third time, the prohibitions turned into these Immortal Runes actually fought with the previous two prohibitions, and the thirty-six prohibitions he arranged couldn't be suppressed.

"Oops, the innate divine prohibition of the three wood attributes is actually incompatible!" Seeing this situation, Chen Xian frowned, but he was not too panicked, he also considered the incompatible situation of the prohibition, but he didn't expect it to come so quickly.

"If you want to go outside, you must first settle down inside", it sounds very reasonable, but Chairman Chiang has already told us a truth with his failure, but in the face of foreign invasion and the danger of destroying the country and extinction of the species, we must unite as one and expelle dissidents in order to survive.

Looking at the thirty-seventh and thirty-eighth prohibitions that were fighting with each other because of the addition of the third batch of immortal runes, Chen Xian secretly scolded for being stupid, and was released from suppressing the new immortal runes, and intentionally injected immortal yuan into them to increase their power, so as to oppress the two prohibitions.

In the face of the oppression of the new prohibition, the double prohibition rose up to resist and oppressed it at once.

However, this is only temporary, they do not have the support of Chen Xian's backup, and after their potential explodes, they will die down and be defeated by the invaders.

There is a song that sings well: "Unity is strength" When the two layers of congenital were forced into a corner, the territory fell, and there was no way to retreat, finally put aside their prejudices, joined hands, and stubbornly defended their own place and the last trace of dignity as an innate immortal aura.

Chen Xian saw that the two prohibitions were almost run-in, and after being inseparable from the continuous and inseparable prohibitions of the other prohibitions, he finally sounded the horn of counterattack, regained the lost ground, trapped the invaders under the wall, besieged layer by layer, and the thirty-six layers of prohibitions took turns to fight, and the two innate gods forbade high-intensity attacks, and finally made the invaders surrender and became the thirty-ninth layer of the sword scabbard.

"Shhhhhh As long as it is an instant, the entire Yong'an City can be erased from the map, whether it is the best furnace refined by the three stars, whether it is Chen Xian, or the demon immortals in the city, as long as it is an instant, it will disappear and never appear again.

wiped the cold sweat on his forehead, and took back the Donghuang Bell in the Qingyun that appeared in Qingyun, and then began to refine the treasure again.

It turned out that he was sacrificing the Donghuang Bell just now, and as long as it was slightly bad, he would put the Donghuang Bell under the hood and suppress the explosion, but it was not used.

On the road again, Chen Xian was a lot more cautious, and when he entered the new immortal rune, it was no longer a yuan by yuan, but one by one, invading little by little, and the water drops pierced. Convert all of these immortal runes into the scabbard's own prohibition.

An hour later, only a scabbard with a blue background and white silk was gradually cooling in the furnace, and the divine light on it was incomparable, and the blue and white air rushed upward, showing the world its extraordinary.

"Boom!" the air from the scabbard rushed upwards and slammed into the closed lid of the furnace with a roar, and the furnace vibrated for a moment.

"Boom, boom, boom......" The waves of air on the scabbard continued, hitting the lid of the furnace one after another, causing the furnace to shake for a while.

With a "bang", the furnace lid was knocked into the air, roaring into the sky, hitting the forbidden bounce on the top of the temple, and slamming it on the ground.

The treasure light in the furnace of "Xiu ......" soared into the sky, and a blue and white light broke out of the furnace, hovering in the hall, drawing a line of blue and white silk, like a hair.

Chen Xian's heart moved, and the blue and white light turned around, and quickly came to him, flying around him.

He slowly raised his left hand, grabbed the blue and white streamer in his hand, and looked at it, it turned out to be a scabbard full of fine scales.

"Good, good!" Feeling the majestic power on the scabbard, Chen Xian couldn't help but admire.

Forty-three prohibitions can only barely be regarded as ordinary acquired treasures, but because there are seven innate gods forbidden in it, the quality of this scabbard is ridiculously high, and it feels no worse than the terrifying sledgehammer of the Lion Camel King. The level of the acquired treasure has some of the characteristics of the innate spirit treasure, and it is indeed a rare treasure.

"Xiu ......" held the oolong sword in his right hand, and after dancing a sword flower, Chen Xian inserted the oolong sword into the sheath with his backhand and closed it tightly.

Chen Xian felt it, after the oolong sword was inserted into the scabbard, it was no longer emitting heat from the outside all the time as usual, consuming itself, and couldn't help but nod with satisfaction.

Let's not talk about whether this scabbard can make the oolong sword raise the Zhiyang sword qi, just not letting the oolong sword empty the power reflects its value, not to mention that this scabbard is still an acquired treasure.

"Well, this scabbard is also an acquired treasure, so you have to give it a name. After putting the oolong sword into the scabbard, Chen Xian stroked the soft and fragrant osmanthus scabbard and pondered.

"The scabbard is Zangfeng, but if it is named Zangfeng, it is too ordinary and casual, and it has to be named with a deep meaning. Since it is the scabbard of the Oolong Sword, let's call it the Hidden Dragon!"
