As soon as the Zixiao Sword was inserted into the ground, a purple halo appeared around the Zixiao Sword, wrapping the Zixiao Sword.

Yi Xuan sat down cross-legged beside the Zixiao Sword, his hands forming mysterious handprints. As these handprints were formed, purple seals appeared. These purple Xuan Seals are like old words, mysterious, noble, and inviolable, and they are many times more powerful than the feather-white Xuan Seals cast by Li He and others.

These Xuanyin are recorded in the Mixed Yuan Sword Technique, which is all-encompassing, and is created by the Giant Supreme with reference to the Xuanyuan Continent's Xuangong and the Realization of the Chaos Dao, far surpassing all the Xuanyuan Continent's Xuangong skills.

Although the Mixed Yuan Sword Technique is based on sword cultivation, it also includes the cultivation methods of body and law masters as an aid.

However, although it is only an auxiliary, how powerful the Mixed Yuan Sword Technique is, far surpassing all the Xuan Gong in the Xuanyuan Continent, even if it is only an auxiliary Xuan Seal, it is far more powerful than the Xuan Seal cultivated by Li He and others.

These purple seals flew into the Zixiao Sword one by one, merging with the Zixiao Sword.

As the purple Xuan Seal merged into the Zixiao Sword, the purple halo that originally only wrapped the Zixiao Sword quickly began to grow, ten meters, fifty meters, and a hundred meters After about ten breaths, it was seen that with the Zixiao Sword as the center, an oval purple circle of light ten miles long, two miles wide, and one mile high was formed.

Although this purple halo does not include all of the pyrotechnics, it also includes most of them.

Yi Xuan's movements of the seal on his hands were faster, and as the last handprint was completed, Yi Xuan suddenly let out a loud cry.

"Devour the realm, become!"

With Yi Xuan's loud shout, the entire volcano shook. Some rocks that were not very solid also fell into the magma from this shock, gurgling, and melting.

The vibration stopped, and after about a few breaths, I saw that within the purple halo, all the fire crystals suddenly turned into red lights, surging towards the Zixiao Sword in the center.

For these red lights, the Zixiao Sword did not refuse to come, and devoured them all.

But there was too much red light, and after a while, a one-meter-sized red light egg was formed with the Zixiao Sword as the center. This red light egg is composed of red lights, which intersect with each other and almost condense into substance.

Seeing this scene, Yi Xuan couldn't help but breathe a sigh of relief.

"I finally succeeded, but I didn't expect that just by casting a few Xuan Seals, I would use up nearly half of my soul power. I hope that the Zixiao Sword can be smoothly advanced and become a high-grade mystical weapon on the ground level. At that time, as long as he enters two more grades and becomes a Heaven Rank Mysterious Weapon, Zi Xiao will be able to automatically cast the Devouring Realm, and he will not need my assistance. ”

Yi Xuan's mind couldn't help but relax.

However, before Yi Xuan could relax for long, he saw that as more red light surged over, this red light egg continued to expand, and after a while, Yi Xuan was also enveloped in it. Moreover, the red light egg continued to expand, and it was not until it reached the size of ten meters that the speed of its outward expansion slowed down. However, it is still expanding.

Yi Xuan, who was in the red light egg, immediately felt a burning sensation coming, and this burning sensation gradually spread to his body, and after a while, it spread to all internal organs.

"This red light can ignore my mystic power and directly enter my body?" Yi Xuan looked surprised at the red light that was constantly shuttling in his body.

After the transformation of the Zixiao Sword Devouring Realm, this fire crystal has become a special energy between matter and nothingness, which can ignore anything and shuttle.

"Huh, that's not right!" Originally, Yi Xuan didn't really care about the burning sensation brought by this red light, for his body, which was equivalent to a high-grade mysterious weapon at the human level, this burning sensation was similar to tickling him. But as time passed, Yi Xuan actually felt the pain.

"This red light contains a fire caste attack, this attack is not strong, a single red light, at most, will make a mortal suffer a little burn. But there is a lot of red light, and the damage added up is not small, almost equivalent to a blow from four or five Xuan Shi. ”

"This kind of attack naturally poses no threat to me, but this red light ignores any defenses, and I can't defend against it at all, so I can only let it attack. After a long time, it is reasonable to be injured. Yi Xuan thought to himself.

It stands to reason that when this happens, Yi Xuan should immediately withdraw from this red light egg. But Yi Xuan didn't, because he found another situation.

"This red light attack turned out to be aimed at the body!There is no effect on Xuan Li and the soul!" Yi Xuan looked excited.

There are also many kinds of attacks, generally speaking, most of the attacks of the Xuan Shi are aimed at both the body and the Xuan power, and relatively few are aimed at the soul, and the only ones aimed at the body, except for the fight of mortals, Yi Xuan has never seen it.

If this red light was aimed at both the physical body and the Xuan Force, Yi Xuan would naturally have no choice but to leave. Continuing to stay here will only consume the Xuan power in his dantian in vain, and it will not do any good.

However, now this red light is different if it only attacks the physical body, although the Xuan power in Yi Xuan's dantian cannot resist the attack of the red light, there is still no problem in repairing the damage caused by the red light. After all, although the red light was peculiar, its attack was still just an ordinary fire caste attack.

The Body Xuanshi who had disappeared in Mu Yun Country for an unknown amount of time had already proved that the best way to refine the body was to break it and stand up. In the midst of constant destruction, there is constant repair. This kind of refining method not only has a solid foundation, but also is fast, and it is also a great training for willpower.

Compared to relying only on Xuan Power to strengthen the physical body, this kind of body refining method is much more powerful!

However, this method of refining the body is also flawed, not to mention extremely painful, and it is easy to damage the body meridians of the Xuanshi. Therefore, even if all the Xuan scholars knew that the method of refining the body was good, few of them dared to try.

Yi Xuan originally wanted to give it a try, but he didn't find a suitable force to destroy his body. This power can't be too strong, and it can't be too weak, if it's strong, it will cause irreparable damage to the body, and if it's weak, it won't work.

Originally, the best way was to find a strong person to practice, usually their elders and the like, their strength was strong enough, and they could master the proportions, as long as the people in the Xuanyuan Continent had strong perseverance, almost all of them used this method. Xuan Yunzi was originally an excellent choice, but Yi Xuan didn't want to trouble him because of these trivial things.

And now this red light attack is undoubtedly a relief for Yi Xuan, the attack is not strong, but it can cause damage to himself, it is the best time to refine his body!

"Okay, I'll use this red light to refine my body, and it's best to make my physical body reach the level of a human-level supreme mystical weapon in one fell swoop!"

Yi Xuan's eyes closed, and his mind suddenly sank into his body.

As soon as his mind entered his body, Yi Xuan immediately felt that these red lights were really omnipresent, flesh, blood, meridians, bones, heart, and even the sea of qi and the sea of consciousness were filled with these red lights.

Yi Xuan didn't care about these red lights, not to mention that even if he wanted to, it was useless, his mind came directly to his brain, Yi Xuan wanted to know how much damage this red light would cause to his brain.

The flesh and blood of the Divine Golden Beast had greatly improved Yi Xuan's whole body, and even his fragile heart had reached a point comparable to that of a human-level high-grade mystical weapon. But the human brain is too mysterious, even if it eats the flesh and blood of the Divine Golden Beast, it only raises it to the level of a low-grade mystical weapon at the human level.

At this level of brain, Yi Xuan didn't know if he could resist the attack of the red light. If he can't, even if Yi Xuan is no longer reconciled, he can only choose to leave. Because the brain is so important to people that they can't lose anything.

As soon as his mind reached his brain, Yi Xuan was stunned.

Outside his brain, there is a milky white film surrounding, outside this film, there are countless red lights, but inside this film, there is no red light.

Seeing this milky white film, Yi Xuan felt some familiar feelings in his heart.

"This is," Yi Xuan pondered.

"Kenshin! Yes, it's the heart of Kendo!" Yi Xuan's mind looked at the small milky white sword in the sea of knowledge.

Looking at this milky white little sword, Yi Xuan's heart was a little helpless. He knew that this sword heart was definitely extraordinary, but he just didn't know how effective it was. So far, Yi Xuan also knew that Jian Xin could resist soul attacks and protect the brain from what he had just seen.

As for the rest, Yi Xuan's eyes were completely black, and he didn't even know how to improve the power of this sword heart.

"Perhaps, there is no record of this sword heart in this Mu Yun country, and when I cultivate to a higher level in the future, I will always find information about it when I go out. Since he couldn't find the answer, Yi Xuan didn't think about it.

"Now that my brain is protected, I can also cultivate here without any scruples. ”

Yi Xuan allowed these red lights to attack him, and his flesh, meridians, bones, and heart were destroyed little by little, and Yi Xuan repaired little by little behind this red light.

It's a painful process, little by little my whole body is burned, torn, repaired, and then burned, torn, and repaired again.

This is a very test of willpower, but fortunately, Yi Xuan has been split several times, and his willpower has long been as solid as a rock. This pain, compared to the pain when the dantian was divided, is simply a small thing.

As time passed, Yi Xuan could clearly feel that his physical body was improving little by little. Although it was slow, it was far faster than when Yi Xuan usually cultivated by himself.

I don't know how long it took, but the red light egg stayed at the size of twenty meters, and finally stopped expanding. Although there were still some red lights flying over one after another, they were already on par with the speed absorbed by the Zixiao Sword.

Now the purple light on the Zixiao Sword is already five feet long and wide, as long as it reaches six feet, it means that the Zixiao Sword has been promoted to the level of the upper grade of the earth.

And Yi Xuan also felt that his physical body was much stronger, and it was not far from the level of the best mystical weapon of the human level.

At this time, the stone walls around Yi Xuan seemed to have loosened a little, and a trace of lime fell.

After another period of time, the red light egg began to slowly shrink, and the red light no longer flew from a distance.

The purple light on the Zixiao Sword had already reached five feet and five inches, and it was already very close to six feet.

Yi Xuan felt that his physical body was about to reach a bottleneck, as long as he broke through this bottleneck, his physical body could reach the level of the best human weapon.

At this time, the stone walls around Yi Xuan had begun to shake, and small stones fell from the top from time to time.
