The fetal brain Yuan Dan that is conducive to the Yuecheng Martial Sacrifice Refining Crystal Mirage cannot be learned, otherwise this very special Inner Pill will hatch a new crystal mirage sooner or later, and it will be completely useless.

Leaving the apprenticeship hall, Yuecheng Wu pondered for a while, and did not rush back to Quefeng City, first went to the exchange area opened up by the Bixuan Sect for the disciples in the sect, he stayed in Quefeng City for five years and did not come down once, although he cultivated with tenacity, but there were also times when he was bored, he didn't want to buy something, he just wanted to relax.

No matter how hard you try, occasional relaxation is also necessary, which will make the mental pressure not so great. Today, the place where the items were exchanged seemed a little deserted, and Takeshi Tsukijo walked around casually, and he didn't see anything worth stopping at.

"Why is it a little cold on the mountain in the night, is something wrong?"

Yuecheng Wuzheng groaned, a Bixuan disciple wearing a moonlight robe stepped into this place, there was some blood on his face, it seemed that he had just fought a big battle, and shouted loudly: "Does anyone sell jade bait, I am willing to buy it from the demon beast Neidan!"

This sentence immediately caused an uproar, the preciousness of the demon beast Neidan, usually even if you have money, you can't buy it, those low-level demon beasts that Yuecheng Wu killed on the Wind Continent and Lei Continent have never found the Neidan in their bodies, and the only demon beast he has ever seen with Neidan is the crystal mirage that Meng Shentong and others hunted. Unexpectedly, there would be someone willing to exchange it for jade bait, and more than a dozen people immediately surrounded this Bixuan disciple.

"My nine-colored deer's Neidan, at least five hundred jade bait, if it is inconvenient at hand, there is no need to come and talk, several of my friends are fighting with demon beasts, and there is not much time to wait!"

Hearing the number of five hundred, the more than ten people who came up around looked at each other a little, the disciples in the Bixuan faction are not short of jade bait, everyone will have a few ephedra fairy grass in the immortal city, but it is distributed to the disciples as food, before the Bixuan heart method enters the hall, everyone still has to eat, even if there are saved, they usually change to other things, and no one has so much in their hands.

If these people get together, this number is not large, and the nine-colored deer is a rare spirit beast, and the inner dan color is divided into nine colors, if it is refined into a blade, not to mention the power, just the nine-colored color of this phantom soldier qi blade is very bold and atmospheric, not to mention that the nine-colored deer is born with a fixed spell, and the orb practiced by the nine-colored deer inner dan will also have a certain chance to fix the opponent.

Yuecheng Wu hesitated slightly, he couldn't go out of retreat for five years, most of the time he was practicing hard, and he had accumulated some jade bait, but his Quefeng City only had three ephedra fairy grasses, and he only saved about ten yuan every month, and now there are more than five hundred ephedra bait, which is already all the belongings. He didn't have to want this nine-colored deer's inner pill, although the nine-colored deer was a rare spirit beast, but at most it could only be refined into a low-grade spirit weapon, which was two levels weaker than the fetal brain Yuan Dan of the mirage, and Tsukijo Wu didn't have so much energy to refine it.

The Bixuan disciple in the moonlight robe, seeing that no one answered for a long time, was anxious, and took out a round bead from the pocket on his waist, and the nine-colored glory shrouded in the bead, like an extra layer of faint colored smoke, adding a little more beauty.

Yuecheng Wu's heart moved, and he suddenly said: "I am willing to give out five hundred pieces of ephedra bait, but if this senior brother is willing, he can redeem seven hundred pieces of jade bait of the same level after ten days." He reached out and probed through the Tianluo bag, grabbed more than ten handfuls in a row, and took out all the ephedra bait inside.

"Thank you so much for this junior brother!"

The young man in the moonlight robe raised his hand and threw the nine-colored deer's inner dan to Tsukijo Wu, and without even counting, he put all the ephedra bait into his waist pocket, and with a wave of his hand, he turned into a green qi, and flew out of Hengye Mountain in the blink of an eye.

Yuecheng Wu faintly heard someone muttering: "This kid is also lucky, he can buy the nine-colored deer's inner dan at such a low price, if it weren't for the fact that I didn't bring so many jade bait today......" He smiled slightly, and didn't look to see who the person who spoke was, and pressed his finger on the palm talisman and went back directly to Quefeng City.

He squandered almost all his savings at once, but he didn't have much pity in his heart, not to mention that the nine-colored deer's inner dan was far more precious than the value of the payment, what Yuecheng Wu thought about was that the senior brother in the moon-white robe was not only able to hunt spirit beasts like the nine-colored deer, but also a group of friends, so that people usually have no way to make friends, such a great opportunity to sell personal favors to each other, how much can make more friendship when they meet next time.

After Yuecheng Wu joined the Bixuan faction, except for Meng Shentong, he had never interacted with anyone at all, and his five-year retreat made his social circle very narrow, and he deeply understood the important surname of connections, and he also needed a suitable opportunity to expand his social circle.

He didn't have much hope for the senior brother who sold the nine-colored deer Neidan, but life is like this, hard work may not necessarily succeed, but if you don't work hard, you will definitely not succeed.

Reopened the starlight cover, Yuecheng Wu did not delay for long, and took out the mirage's fetal brain Yuan Dan from the main house, transported the cultivation technique, and entered a fairy power. In the Hundred Swords Diagram, there is a very special immortal sword, called the Invisible Sword, the essence is a qualitative and intangible true qi, thousands of tempers condensed into a transparent small sword, according to the explanation on the Hundred Swords Diagram, this invisible sword flies out of the formless and phaseless, and the enemy cannot detect it at all.

When Takeshi Yuecheng was thinking about how to refine the fetal brain Yuan Dan of the mirage, he remembered the peculiar invisible sword on the Hundred Swords Diagram, and had already decided how to enter the cultivation technique, he just wanted to refine an invisible sword. The mind of the Bixuan faction, the highest realm is the invisible power, borrowing the orb to lay down a kind of military trick, training into a phantom soldier qi blade, just an expedient measure, fundamentally speaking, the mind of the Bixuan faction and the invisible sword on the hundred swords diagram have the same magic, and even the same way.

When the two ideas merge into one, Takeshi Tsukijo is enough to use the mind of the Bixuan faction to reproduce this invisible sword that has long been lost in the legend, this mouth has no way to see, and the blade that can hide all the sword light will become his most powerful killer weapon.
