Yang Chen's purpose in entering Langya Well was to pure yin and true fire. However, the Pure Yin True Fire is a seven-grade fire, and Yang Chen doesn't dare to conclude that the Pure Yin True Fire in the Langya Well has already been collected by someone and can be taken away with a move, so the preparations that should be made are not missing at all.

The most important thing to have is the ability to collect the seven-grade fire. In terms of cultivation, with Yang Chen's mid-infant realm, it is really a bit beyond his power to collect pure yin true fire. But with the Yunling Furnace and the Yin and Yang Burning Sky Flame, this is no longer a luxury, but something that can be achieved as long as you can improve a little.

The Yin Yang Burning Sky Fire has only absorbed the fifth-grade fire now, and in Yang Chen's opinion, it is not yet the time to be able to withstand the seven-grade fire, but the six-grade fire is no problem at all. The fifth-grade fire in his hand has almost been absorbed, and it has reached the point where it is time to absorb the six-grade fire.

As long as you absorb a few more six-grade fires, the power of the Yin Yang Burning Sky Fire will be greatly increased, and it will also be able to withstand the next seven-grade fires. And at this point, you can consider the time to combine the Yin and Yang Burning Sky Fire and your own natal flying sword into one.

The scarred Nanming fire armor was actually an example of the fusion of fire and magic weapons. The magic weapon is fused with fire, not only will there be a qualitative leap in grade, but also a significant increase in power. The ultimate purpose of condensing the flame is for this last step. It's just that there is a choice between the alchemist and the warrior, whether to fuse the alchemy furnace or the natal flying sword.

For most alchemists, this choice is meaningless, because most alchemists' natal magic weapon is their own alchemy furnace. Similarly, for Yang Chen, this choice was meaningless, because Yang Chen's Spirit Furnace itself had the characteristic of fusing the fire to upgrade itself.

As for the flying sword that wanted to fuse the Yin and Yang Burning Sky Fire, Yang Chen didn't have to think about anything else. The Ming Light Sword must be one of them, and the Ding Huo Flying Sword has already been prepared. At that time, the grade of these two flying swords was not high, because the grade of the magic weapon could be greatly improved through this method.

After the live advertisements of several major sect masters, as well as the head of the Pure Yang Palace and several elders, the Seven Emotions and Six Desires Pill has directly become the holy relics of the Yuan Infant and the masters of the Mahayana period who are on the verge of breaking through, not to mention that Yang Chen is just exchanging some top-level Xinjin materials, that is, in exchange for more advanced things, it is not a problem. Especially the five major sects, after tasting the sweetness, they directly used the treasures of the sect to exchange some seven emotions and six desires pills with Yang Chen.

This is true of the five major sects of Daomen. The Demon Sect and the Scattered Cultivation Alliance were no exception, and they all took out the secrets of their own sects and came one after another. After the matter of sealing the demon array last time, Taitianmen surprisingly didn't say anything more about this exchange in the Pure Yang Palace this time, as long as this exchange didn't happen under their noses. They also turn a blind eye.

Less than two years after Yang Chen released the exchange news, Yang Chen had a lot of top-level Xinjin materials in front of him. Every material here, placed outside, is a coveted good thing, and you can casually refine a fine Xin Jin Flying Sword. But in Yang Chen's eyes, this level of material is not enough.

For the rest of the materials, Yang Chen gave a very generous filial piety to the palace master. The master of the sect already has a natal flying sword, but his double cultivation

Daoist Wan Qian doesn't have a particularly suitable natal flying sword. These materials are enough for Wan Qian to refine a handful.

For Yang Chen's filial piety, the master of the Sect Sect accepted it with peace of mind. He also knew Yang Chen's plan, but he just reassured Yang Chen. The affairs of the sect, he can still worry about it for a few hundred more years, and he doesn't need Yang Chen to be distracted at all. The Sect Master was already extremely satisfied with Yang Chen, and not only gave himself a beautiful double cultivator. And it's the kind that is obedient to 100 people, especially to improve their cultivation. Help yourself to strengthen the sect, if such a disciple is not satisfied, it will be unreasonable.

Xin Jin is also known as soft gold, which is the essence of Taiyin, so this Xin Jin flying sword is destined to be a soft sword. Yang Chen did not directly refine the flying sword, but mixed the dozens of materials selected according to the secret recipe in his memory, and then melted them together with yin fire, and then threw them into the sea of knowledge, and he was able to refine the natal magic weapon from the beginning of the material.

Not only that, but the Yin Fire Dragon in the Sea of Consciousness was directly coiled on this huge piece of Xinjin material, and it did not use its own flame to smelt all the time, and in this case, the wisps of impurities in the fused material were eliminated little by little.

This process will take at least a few decades, and Yang Chen is not in a hurry, anyway, there will be almost eighty years before the opening of Langya Well, which is enough for Xin Jin Fei Sword to refine.

Yang Chen's energy at this moment was all focused on absorbing and fusing the six-grade fire. After dealing with the Xin Jin materials, Yang Chen and his wives and concubines went into retreat again.

In fact, Gao Yue and Gongsun Ling have never been out of the customs, and it is only Yang Chen's seven concubines who have gone out. In this retreat, Yang Chen summoned the seven women to his side, and after telling them some precautions, he directly released the Nine Shadows Flying Sword, slowly releasing the demonic energy from light to thick, and wrapped the seven women in it.

A long time ago, Yang Chen said to the Seventh Girl that the Seven Emotions and Six Desires Pill were deceitful goods, and the Seventh Girl never believed it. After seeing the demonic qi at this moment, I realized the power of the demonic qi. The Seven Girls, who had all experienced the taste of the Seven Emotions and Six Desires Pill, immediately understood that the Seven Emotions and Six Desires Pill was just a weakened version of the demonic qi with a little heavenly tribulation breath, and compared to the pure demonic energy, it could really be called garbage.

They are all masters of the Mahayana period, and everyone understands the benefits of tempering this kind of demonic qi, and the seven girls immediately devote themselves wholeheartedly to the confrontation with demonic qi. It's just that, compared with Yang Chen's four wives, although their cultivation is all in the Mahayana period, their divine sense cultivation is not a little worse than that of all women, and they have not experienced the experience of the Demon Continent, and the demonic qi they have endured is much weaker, almost less than half of the four women.

Even so, the seventh daughter is already struggling, and at the same time, she has benefited a lot. This kind of demonic qi that directly awakens the amplification of various emotions in the heart is simply a training ground for inner demons, allowing them to be in the outbreak of inner demons anytime and anywhere. The Seven Maidens couldn't take care of anything else at all, so they could only concentrate on the confrontation and forget everything around them.

After seeing the seven women enter the state, Yang Chen took out the six-grade fire on his side and began his usual absorption and fusion process. First use the Spiritual Furnace to absorb the fire, and then through the Spiritual Furnace, absorb it into your own body. Of course, merit is also necessary to add merit in the process.
