Wei Wuji only refined the meridians of his hands, and he was about to refine the meridians of his feet.

If it was an ordinary cultivator, the body would have been refined a long time ago, and the meridians would have been destroyed, and it would have become a wasted person. But Wei Wuji is different, his body's internal organs are sword qi refining, extremely strong, and can withstand the torture of refining veins.

Returning to the nine-person sword formation of the ninth level, Wei Wuji drove with all his strength, and finally in the sword formation, he persisted for five hundred breaths, which was almost an hour.

"I don't know how long the meridians of my feet can last after they are refined. Wei Wuji lowered his head and pondered, and then began to prepare, refining the meridians.

A few days later, Wei Wuji's bipedal meridians were also successfully refined.

At this time, Wei Wuji's strength had almost doubled compared to when he entered the refining period. Entering the nine-person sword formation, Wei Wuji's figure advanced and retreated, just dodging the defense, and he could remain invincible with ease. In the end, his physical strength was exhausted, and he struck to defeat the Array Spirit.

Standing at the tenth level, Wei Wuji looked at himself in the field, and the nine swords came out together, roaring and attacking.

The human form also flew with nine swords, fighting back with the same sword formation. In the end, Wei Wuji fell short, and he returned defeated.

"There is still one last point, and the grasp of sword intent is already close to the purest artistic conception of the sword. If the strength can be improved a little more, not only can you break through the formation spirit of the tenth level, but you can also fully grasp the artistic conception of the pure innate sword. ”

Wei Wuji thought of this, ready to start refining his heart vein.

After the preparations, Wei Wuji sat down, only to find that just the innate sword qi in the magic circle, and the power of his true qi to derive thunder, could not refine the heart vein.

The strength of the nine heart veins is too much more than the hands and feet, and only the assistance of spiritual energy can be refined.

"All the sects in the world, every cultivator cultivates, all of them are tempered with aura, and there is a reason for it, aura is the foundation of cultivation. ”

Wei Wuji withdrew from the circle and rebuilt and set up two connected rune circles. Then, he came to the outside world, ingested the aura of the snow-capped mountain into the magic circle, and then entered the realm of ancient paintings, and ingested the innate sword qi into another magic circle.

After doing all this, Wei Wuji sat down at the junction of the two magic circles, put out more than 5,000 spirit stones for backup, and then began to refine the heart vein.

I saw that his hands were empty, and the spiritual energy and sword qi on both sides flowed out of the magic circle and were sucked into his body by him. After his body gradually expanded and reached a certain limit, Wei Wuji used his true qi to derive the power of thunder, mixing sword qi and spiritual qi, and began to refine his heart veins.

Three days later, Wei Wuji consumed all the sword qi and spiritual energy in the two magic arrays, and the more than five thousand spirit stones in front of him were also consumed, and the heart vein was finally successfully refined.

Standing up, Wei Wuji closed his eyes and intently, feeling a strange change in his heartbeat.

True Qi reaches the heart, and the heartbeat can be sent and received freely, controlled by him, and can be reduced to a very small state, equivalent to nothing, or it can beat violently, like thunder and agitation.

The biggest gain is that the innate artistic conception of the sword has reached the purest realm without the slightest contamination.

At this time, Wei Wuji held each long sword, it was like an arm, and if he looked closely, each sword contained its own sword intent, which was not the same. Bending his fingers lightly tapped the sword body, ding, a clear sound rippled like water ripples, in Wei Wuji's thoughts, as if a spiritual creature spoke, the sword spoke.

In the scriptures of sword forging, the sword spirit is recorded.

It is said that each person's weapon, when familiar with the master and nurtured to a certain extent, can nurture spirituality.

No matter how strong the spirituality is, it can evolve into spiritual objects, the weapon understands the master's heart, can automatically protect the master, and even in the end, it can also evolve into a form visible to the naked eye, which can be in the form of a beast or a human form, which is the so-called sword spirit.

Wei Wuji knew that cultivators could also condense various forms when they attacked and killed. But that is all the strength of the cultivator, and it has nothing to do with the sword weapon.

Some sword weapons can evolve when attacking, but that is all the effect of runes. The blade engraved with the rune can transform into a beast form to attack and kill the opponent when attacking.

There is also a formation spirit, which is also a condensed human form under the action of runes.

The sword spirit, on the other hand, is the weapon itself, which is nurtured and generated by other powers, and then evolved into a form.

Wei Wuji has never seen such a thing, the records in the classics are just records, and it is better to believe in books than to have no books. At this point, Wei Wuji never blindly followed, and of course he did not object, he only believed that seeing was believing.

After cultivating for a few days, Wei Wuji recuperated, and then came to the tenth level.

The formation spirit evolved to show Wei Wuji's appearance, standing in the middle of the field, Wei Wuji stepped forward and attacked and killed at close range. Two identical figures fought together in an instant.

The sword qi in the field was agitated, flying sand and stones, and the reality could not be seen, only two faint phantoms could be seen, confusing, as if in the street market at night, the ghosts and shadows were in general.

After half an hour of fighting, Wei Wuji finally won, and finally passed the tenth level with his true strength.

The fluorescent light flickered in the field, and a portal was derived, and an idea came, telling Wei Wuji that he had successfully broken through the level and could enter the portal.

Wei Wuji looked at the portal and stepped inside. The next moment, he was teleported into a stone chamber.

There is no superfluous decoration in the stone room, and there are bluestone walls on all sides, and in the middle is a cumbersome rune array. In the center of the circle, five feet in the air, a fist-sized fluorescent cloud floated.

Wei Wuji walked over and grabbed the fluorescent, and the fluorescence shattered and disappeared, but a thought entered Wei Wuji's consciousness. Wei Wuji's body instantly stiffened, like a puppet, closed his eyes, and stopped in place.

After a long time, Wei Wuji slowly opened his eyes, and there was a look of horror in his eyes, "I can't imagine that this ancient painting scroll is actually a magic weapon......!

In the thoughts that came, everything was explained.

Ancient paintings are offensive magic weapons that can drive the array spirit out of the picture scroll and attack and kill the opponent. The power of the array spirit's attack was amazing, roughly equivalent to ten times the strength of Wei Wuji. But the price is too high, and it requires 10,000 spirit stones, and it can't be replaced by essence stones and essence stones.

30,000 spirit stones shot once, the power is ten times that of oneself, and only one shot, no matter whether the opponent is dead or alive, never shoot twice.

A full 30,000 spirit stones is definitely not a small number. Wei Wuji was completely shocked by such a price.

As the deputy sect master of the Guiyuan Sect, Liuyunzi only carried a few thousand spirit stones with him. The cultivation resources of the Northern Wizard Hall are poor, and the dignified ancestor only has more than 7,000 spirit stones around him. The first person of the dignified sect, the sect master of the Xuantian Sect, Ling Hu Xuantian, for the compensation of 10,000 spirit stones, completely destroyed his image, put down his old face and bargained, like a market vendor.

But what shocked Wei Wuji the most was that the 30,000 spirit stones were just the initial drive, if the spirit stones increased, the attack power of the array spirit would be even stronger!
