It took a lot of effort and more than a thousand exchange points to finally kill Kui Niu. In addition to getting two thousand exchange points, Liu Feng also got the corpse of the Kui Niu in front of him.

The magic weapons and talismans exchanged through the exchange platform, regardless of level and power, can only be used once, which is not a long-term solution for Liu Feng who wants to gain a foothold in the desolate world. Facing the corpse of Kui Niu in front of him, what Liu Feng has to do now is to refine his own magic weapon.

Liu Feng remembered that in the ancient classics, the "Yellow Emperor's Neijing" once recorded this Kui Niu, when the Xuanyuan Yellow Emperor went out to conquer Chiyou, and the Nine Heavens Xuannu made 80 Kui cowhide drums for the Xuanyuan Yellow Emperor.

Xuanyuan Yellow Emperor and Chiyou Wuren decisive battle in Jizhong, set down the "Qimen Dunjia" array to besiege the Chiyou tribe, a shock of 500 miles, a continuous earthquake of 3,800 miles, only to see the whole battlefield shake the mountains, the sky swirls, shouting to kill the Chong Xiaohan, so that the Chiyou soldiers are fascinated, rushing to kill no way, defeated like a mountain.

It can be seen that the Kui Niu drum made of Kui cow leather is really extraordinary.

Although compared to those innate spirit treasures, I don't know how much worse, but for Liu Feng, who is now empty-handed and has only one virtual exchange platform, there is a cow drum in his hand, and in this desolate world where there is a crisis everywhere, at least a little more self-preservation.

However, if you want to practice a magic weapon, where is it so easy, not to mention that Liu Feng has no cultivation at all now. Previously, because the exchange points were very small, Liu Feng didn't dare to use them to exchange cultivation exercises at all, and they were all reserved to deal with the dangers that would arise at any time. If it weren't for these exchange points, this time I accidentally touched Kui Niu's nest, and I would have hung it there.

Now, with two thousand exchange points, Liu Feng can at least exchange for the lowest level of cultivation exercises on the exchange platform. Liu Feng looked at the low-level exercises on the exchange platform, and there were only three "Qi Cultivation Essence Technique" with 1,000 points below two thousand points, "Five Elements Qi Gathering Technique" with 1,500 points, and "Three Yuan Thunder Technique" with 2,000 points.

Even people who don't have any common sense of cultivating immortals can know from the number of the exchange points they need that the "Three Yuan Dun Thunder Formula" is the best of the three cultivation techniques that Liu Feng can exchange at present. However, Liu Feng did not exchange this "Three-Yuan Thunder Technique", but instead exchanged the "Refining and Refining Qi Formula" with the least number of exchange points.

Liu Feng chose the "Refining and Refining Qi Technique", not because this "Refining and Refining Qi Technique" can be better than the other two methods, but because the exchange points are really insufficient, and Liu Feng can only retreat to the second. He's also going to have to leave some life-saving exchange points in case he needs them.

At the same time, if you want to refine magic weapons, it is absolutely impossible to do without special refining techniques, Liu Feng has long been optimistic about a "General Outline of Practicing Weapons" on the exchange platform that requires an exchange point of 500.

As soon as the white light flashed, two quaint books appeared out of thin air in Liu Feng's hands, one was the cultivation method "Refining and Refining Qi Technique", and the other was "General Outline of Cultivation Instruments", with these two books, Liu Feng finally had a little capital to gain a foothold in the desolate world. At the same time, Liu Feng's exchange point is only 500 points left.

"Eh! I'm poor again...... "Looking at the exchange point of only 500, Liu Feng couldn't help but feel a little sorry for himself.

Holding the lowest-level cultivation technique "Refining and Refining Qi Technique" on the exchange platform in his hand, Liu Feng slowly opened the page, but his heart was thinking about the highest method of cultivation between heaven and earth, "Huangting Neijing Sutra".

"The Yellow Court Inner Scene Sutra" is the ultimate cultivation method of Hongjun's opening preaching, almost all of the three thousand avenues are included, and only a limited number of people such as Sanqing and Nuwa can hear the "Yellow Court Inner Scene Sutra" taught by Hongjun. However, they all combined the "Huangting Neijing Sutra" with their own comprehension and formed their own exercises.

But the exchange of "Huangting Neijing Jingjing" actually requires an exchange point of 100 billion, and Liu Feng doesn't know when he can get it. Returning to reality, Liu Feng put all his spirit into reading "Refining and Refining Qi Recipe".

There are no complicated formulas, no connotations that are extremely difficult to comprehend, only the route of exercise and the outline of the mental method. Liu Feng followed the above step by step, meditating next to Kui Niu's corpse, drawing qi into the body, refining and refining qi.

Call......

After a big week's luck, Liu Feng felt that his whole body was sticky, and it seemed that this week's luck had excreted all the impurities in his body from his pores.

"It's so cool, but ...... The smell on his body is so heavy......" Liu Feng felt as if his body had undergone a whole wash, and his whole body was extremely relaxed, and at the same time, there seemed to be a slow surge of air in the dantian. However, the stench on his body immediately pulled him back from that good feeling.

For this reason, Liu Feng didn't care whether Kui Niu's corpse would be dragged away by other demon beasts, so he quickly ran to the nearest river, took a comfortable bath, and washed off all the dirt removed from his body.

With the practice of cultivation, Liu Feng seemed to fall in love with this feeling of washing the essence and changing the essence, accepting the baptism and cultivation of the spiritual energy of heaven and earth, and temporarily put aside the matter of refining the magic weapon, and just relied on Kui Niu's corpse to practice for a month.

I have to say that this desolate world is really full of spiritual energy, and in a month's time, Liu Feng's cultivation is still the lowest level of "Refining and Refining Qi Technique", and he has already refined the essence of his body into the dantian, breaking through the introduction of qi into the body and refining and refining qi all the way, and stepping into the cultivation of refining qi and transforming gods.

As long as you break through again to reach the refinement of the gods and return to the void, after the baptism of the heavenly tribulation, you can cultivate into a heavenly immortal.

"This desolate world is really a good place to cultivate, if it is placed in the later generations when the spiritual energy is declining, I don't know how many hundred years it will take to cultivate to reach the god of refining qi, and now in this desolate world, it only took me a whole month to break through to reach the god of refining and transforming the god. After reaching the Qi refining God, I have the true yuan mana, and I can use those powerful magic weapons on the exchange platform, and I don't have to limit myself to using thunder beads and talismans. ”

After a little operation of the True Yuan mana in his body, Liu Feng felt that a month of hard cultivation had not been in vain. Even if he had exchanged for a high-level magic weapon before, a Chaos Arcana such as the Chaos Clock, he didn't have enough True Yuan mana, so he couldn't use it at all, and he could only use it in his hand as a vase ornament.

But now it's different, reaching the cultivation of refining the gas and transforming the god, it can be regarded as a threshold for stepping into the cultivation of immortals in the desolate world, because when the refining and refining god has the primordial god, he has the ability to ask for **restraint, even if he dies, the primordial god can still continue to cultivate after escaping.

Similarly, after having the primordial god, there is true fire, and you can refine the magic weapon.

Although Liu Feng has been immersed in cultivation day and night for the past month, he is still thinking about refining a magic weapon of his own.

A month passed, and the corpse of the Kui Niu was slowly eroded by the aura of heaven and earth and turbidity, and finally only a complete Kui Cow skin and the complete skeleton of the Kui Niu remained.

"General Outline of Exercises" Liu Feng was already familiar with it in his heart, a mouthful of real fire erupted from his mouth, shot at Kui Niu's shriveled corpse, and then mobilized the aura of heaven and earth with both hands to assist in refining.

Fortunately, this is in a desolate world, and the aura between heaven and earth is sufficient, and it is almost liquid, so Liu Feng doesn't need to worry about the lack of aura that urges the Danhuo, so he has been spraying the Danhuo to refine the cowhide and bones.

Another month passed, and the Kui Niu leather and Kui Niu skeleton were refined smaller and smaller under the true fire of Liu Feng, and finally the whole thing turned into a small drum, with a single horn on the drum, and the remaining two humerus bones were refined into drumsticks.

"The Kui Niu Drum has finally been practiced ......"

Liu Feng held the successfully refined Kui Niu Drum in his hand, gently stroked the drum surface, and couldn't put it down, this was his first real magic weapon, and it was also refined by himself, although it could not be compared with the power of those innate spirit treasures above the level of immortals, but in this way, Liu Feng also had a magic weapon for self-defense, and there was no need to consume the exchange point every time to exchange the magic weapon of the surname.

At the same time, in the past month, he has continued to use true fire to refine the Kui Niu Drum, and Liu Feng's cultivation has also faintly reached the peak of refining qi and transforming gods, and he is only one breakthrough away from being able to refine the gods and return to the void.
