Lu Xiaonan didn't go back immediately, but took Liu Yinyin to popularize her knowledge about cultivating immortals in this forest with sufficient aura, and also took Liu Yinyin to the real center generation for a walk, and visited the demons in the forest by the way.

And the demons bartered, the monkey demon needless to say must be exchanged for some monkey wine, the tiger demon is some good quality spirit grass, the most precious thing for Lu Xiaonan is the wood heart of a five-thousand-year-old man-eating vine sent by the cannibal vine, when he received this thing, Lu Xiaonan had a general idea in his mind, from Lu Xiaonan's point of view, this is an active sword embryo, when a sword is still a sword embryo, in addition to having superb refining techniques, the most important thing is the activity of the sword embryo, the more sufficient the activity of the sword embryo, When the sword is formed, there is a great chance that the sword spirit will be born, but Lu Xiaonan is a little troubled, if this sword is refined, there is no one around her who can use it, cannibal vine or something, some are too cruel, this thing has blood and brain marrow, if it is refined into a sword, the sword spirit is definitely a guy with evil intentions, although Mu Xin, who is five thousand years old, should not be very interested in drinking blood, but not daring to be interested does not mean that it will not be!

Such a precious thing, Lu Xiaonan didn't take advantage of the cannibal vine Xiao Xiao, what Lu Xiaonan took out was a cushion, the aura contained in this cushion was enough for Xiao Xiao to cultivate to the Mahayana period, and there was also an automatic spiritual gathering circle in it, for Xiao Xiao, this object was not precious, and it was sent in time, she had advanced to the formation period for some years, and when she reached her realm, now these rare aura, even if she cultivates every day, she can't advance at the end of her life, and now she is just living a life of waiting for death, When she gave up her cultivation, she thought that it was better to play carefree like waiting for death than to work hard, but in the end it was an empty impact, with Lu Xiaonan's spirit gathering futon, Xiao Xiao was complete in an instant, even if she had no heart and lungs before, there was still a lot of unwillingness hidden in her heart.

Some people may say, why not take Mu Xin to absorb, that is the crystallization of five thousand years of man-eating vines, in fact, Mu Xin is not like the Demon Pill, the Demon Pill is actually the embodiment of the aura of each demon, that is to say, the Demon Pill is the form of the aura condensed to a boundary, Mu Xin is not, Mu Xin is not a simple aura condensation, but a part of the Tree Demon itself, it can be said that Mu Xin is another life of the Tree Demon, but it is different from the formation of the Tree Demon, Mu Xin is not a tree species, in fact, it is not a living thing, but it is active, This kind of activity depends on the level of cultivation of the dryad before death, like the cannibal vine wood heart in Lu Xiaonan's hand, if the sword spirit produced after refining the sword is actually the previous life of the dryad, although it does not carry the previous memory, but it is the same as the character of the previous life. Mu Xin itself will absorb the aura of heaven and earth, if you don't have a cultivation higher than Mu Xin's original body and want to absorb its aura, then you don't know whose aura is sucked dry, just like an evil cultivator with a low cultivation who wants to absorb a cultivator who is higher than him, it is a unilateral death.

Lu Xiaonan is very thoughtful for the sake of the public, refining such a dangerous thing, or not to go back to the city to harm the innocent, directly found an empty place in the jungle, opened a temporary cave nearby, sent Liu Yinyin in, and told her to cultivate hard, and he opened the enchantment, released his own fire spirit silence, and supported the silence to control the firepower to a minimum, so that Mu Xin could slowly get used to silence, because the material this time was Mu Xin, Lu Xiaonan would no longer add any auxiliary substances, otherwise he was afraid that the sword spirit that was bred would become four different, After three days of silence under the forging of gradually increasing firepower, Mu Xin did not turn into a liquid like other refining materials, but began to soften, and when the full moon was the heaviest yin at night, Lu Xiaonan began to play a string of laws against Mu Xin that were getting faster and faster until they were invisible, and after the blessing of these strange laws, Mu Xin began to transform constantly, as if a naughty child lived in it, punching here, kicking there, as Lu Xiaonan's last law decision fell, Mu Xin suddenly sent out a seemingly soft burst, In fact, it does not lose the sharp cold light, a dark green bladeless long sword was formed, although this sword is bladeless, but it is not as harmless as it seems, as a sword refiner, the attributes of this sword Lu Xiaonan is very clear, this sword with the user's cultivation, within a certain range, can invisibly cut off the vitality of any living thing, making people unguardable, but at this moment this sword is not finished, when the emperor flow slurry that appeared at midnight on the fifteenth day of each month appeared in this sky, Lu Xiaonan saw the opportunity and grabbed one of the drops, Integrate it into the heart of the long sword, officially awaken the sword spirit, and name the sword without a trace, a streamer from the sword body, the word no trace fell on it, at this time it is considered to be completed two-thirds, and the remaining one-third is the thunder tribulation caused by sword refining outside the enchantment.

The enchantment opened, Lu Xiaonan was also frightened, he knew that the thunder tribulation of this sword was absolutely extraordinary, but he didn't expect to directly attract the powerful yin thunder of the Netherworld Thunder Tribulation, it seems that the yin and evil qi of this sword are the top priority, and it is really not something that ordinary people can use, if the sword spirit does not usually restrain these breaths, I am afraid that even the cultivators of the Mahayana period will not be able to bear it. God really doesn't give life, even if the Netherworld Thunder Tribulation is over, there are still nine hundred and eighty-one ones, the final situation is okay, although the traceless has fallen crookedly to the ground, but after all, it has survived, the compensation after the thunder tribulation is still very kind, and the traceless will be refreshed and energetic after a while, although Lu Xiaonan did not accept this sword for his own use, but because living creatures have nestling plots, the sword spirit without a trace is no exception, for her, Lu Xiaonan is equivalent to a mother-like existence.

……

Liu Yinyin looked at the young girl eating barbecue, a little entangled, how could that ladylike girl eat so much, the first impression is really deceiving, think about the scene when Lu Xiaonan came in with a trace, traceless was wearing a dark green light ancient dress, a long black hair that occasionally flashed in the sun, casually tied behind her head with a hairband of the same material as the skirt, her face was fresh and elegant, and there was a faint pear vortex when she smiled, which did not look like a mortal.
