"Heaven Devouring Technique!" Li Muran only heard this name, and he felt that his spirit was extraordinary, and sure enough, the methods of the Immortal Family were unimaginable to these Nether Realm cultivators.

Huoyun continued: "Speaking of the basic essence of this Heaven Swallowing Technique, it is related to the monk's dantian. Li Xiaoyou also knew that since the immortal cultivators opened up the dantian spiritual aperture, the dantian has been constantly changing with the improvement of cultivation, and every time the great realm advances, it is accompanied by a qualitative leap in the dantian. ”

"For high-ranking monks, the dantian already calls itself space. There is a Tao Fayun: One person, one world, which refers to the dantian in the monk's body. ”

"Just as Li Muran's own dantian can already be regarded as a small world, so that strange grass can grow in Li Daoyou's dantian, and Li Daoyou's natal treasure can also be stored in the dantian, and the true yuan in the dantian is constantly tempered and improved in quality. ”

"The controller of the dantian world is naturally the monk himself. If the dantian world became stronger, the monk's own mana cultivation would naturally increase. It is precisely this purpose for us to continue to meditate and cultivate, to draw the essence from the surrounding heaven and earth vitality, and to refine and introduce it into the dantian through the eight veins of the guòqi meridian, so as to become our own true essence and strengthen the dantian. ”

"And the Heaven Swallowing Technique, is to swallow the existing spatial interface directly into the dantian world, and with its own supernatural powers, the spatial interface into its own dantian world, if it can be completely merged, then the dantian world will completely absorb all the vitality contained in the swallowed spatial interface at once, and the power of the law contained in the spatial interface can also be used by the monk himself. ”

Li Muran was shocked when he heard this: "Merge the outside space into the dantian world?

Huoyun nodded: "With your current cultivation, of course, it is impossible to do it with your own strength. However, if you have a Heaven Mending Stone in your hand, it will be different!"

"After all, the Heaven Mending Stone is an immortal material, and it itself contains a powerful and stable interface power. If you first use your own bloodline to continuously refine the Heaven Replenishing Stone, so that it gradually coincides with your breath and no longer rejects it, and then you use the Heaven Replenishing Stone to refine a space that is not too large, with the help of the interface power contained in the Heaven Replenishing Stone, wrap that space, and according to the key of the Heaven Swallowing Technique, merge the space that the Heaven Replenishing Stone refines into your own dantian world, it is possible to succeed. ”

"And once you succeed, not only will your mana immediately advance, but also you may comprehend a stronger power of the law from the swallowed spatial interface, how much you can comprehend, whether you can succeed, it depends on your personal understanding and creation, and the old man does not dare to guarantee this. ”

The more Li Muran listened, the more excited he became: "I see! According to the seniors, how likely is it that the juniors will succeed in performing the Heaven Devouring Technique now?"

Huoyun said: "It depends on how big your own ambitions are! The larger the space interface you want to devour, the more benefits you will get, but the greater the difficulties, and the smaller the chance of success! If you only want to devour a small piece of space, the success rate can almost reach more than ninety percent, but the effect will not be too significant, and you will not get too many benefits." ”

"Moreover, you only have one mending stone, so you only have one chance. With the quality of the Heaven Replenishing Stone, it is completely possible to refine a very large space, so large that it is impossible for you to swallow it at all! Therefore, in the end, how much space you want to refine is completely determined by your own measurement. ”

Li Muran fell into a deep groan, it seems that this Heaven Swallowing Technique still needs to be carefully weighed. This kind of opportunity is hard to come by, only this once, if you are too conservative and the refining space is too small, you will not get too many benefits, maybe it is just a few more decades or hundreds of years of mana, but if you are too greedy, it is likely that you will not be able to refine successfully, and finally have to expel the refining space out of the dantian, and can only be used as a portable cave similar to Langhuan Dongtian, then it will be a complete waste of this hard-won precious opportunity!

Huoyun said, "There is no need to rush this matter. Li Daoyou still needs to use his own blood to nourish this mending stone, and it will take a long time before his own dantian can gradually merge with it. The specific method, the old man can teach Xiaoyou, Xiaoyou is doing this step first, as for how much space to refine in the future, it will be at least decades or hundreds of years later!"

"Thank you, senior!" Li Muran nodded and thanked him respectfully.

"You're welcome!" Huoyun smiled slightly: "The old man taught you this method, and he also has his own selfishness. After all, the old man is now sharing the honor and disgrace with you, and your cultivation is not too high, and there are strong enemies coveting it, if you can take this opportunity to improve your cultivation, the old man will be safer. If you are willing to thank the old man for his guidance today, you only need to promise that when the old man crosses the tribulation and flying immortals in the future, he will send the spirit bird Xiaolei to help him overcome the tribulation, and the old man will be satisfied. ”

"This is Xiao Lei's business!" Xiao Lei immediately agreed obediently: "The seniors help the master improve his cultivation, and the juniors will naturally do their best to help the seniors survive the catastrophe!"

"Very good!" Huoyun nodded with satisfaction: "It's a pity that the old man is not proficient in thunder attribute exercises, otherwise, if you can guide your cultivation and let you advance to the Mahayana period, I will be a little more sure when I help me wait for the tribulation in the future!"

Then, according to Huoyun's instructions, Li Muran cultivated a rather complicated mantra, and then transported qi and blood, cut his arm, and flowed out a thin stream of blood, dripping on the Tiantian Stone.

If you don't practice that mantra, the essence blood will drip on the Tiantian Stone, and it will only be left behind, and there will be no blood on the surface of the Tiantian Stone. However, after cultivating the mantra taught by Huoyun, although most of the blood still slipped from the mending stone, a faint trace of blood seeped into the mending stone.

Huoyun said, "Very good! You practice like this, repeating the process of dripping blood every seven days, until the Heaven Replenishing Stone is completely nourished by your essence and blood, and becomes a bloodstone with a red body, you can start refining the space!"

Li Muran thanked him, and then put away the mending stone.

Then, he took out two transparent orbs and seven or eight other light attribute materials from his sleeve.

Li Muran said: "These two beads are the treasures that the juniors snatched from the elders of the Haotian clan with extremely high light attribute talents, and the juniors want to use these two beads as the main thing, supplemented by other top-level materials, to refine a light-attribute natal sword." ”

"The younger generation already has two natal swords at the level of Heavenly Treasure, one is greedy, which is the sword of divine thought, and the other is called dark, which is a sword with dark attributes, and it is very consistent with the Demon Dire Clan's exercises cultivated by the younger generation. However, during the day, except for the Xuantian Ancient Vine that cannot be used lightly, the juniors do not have other suitable natal magic weapons, so if there is a light attribute sword, it will be more convenient. ”

Huoyun smiled slightly: "You sue the old man about this, do you want the old man to guide you in the method of refining weapons?"

"Exactly!" Li Muran nodded: "The cultivation method of the immortal realm is extremely mysterious, it is unimaginable for me and other nether realm cultivators! Presumably, the refining technique of the immortal realm is also the peak, and the younger generation wants to see it!"

Huoyun shook his head and said, "The alchemy technique of the Immortal Realm is indeed much more sophisticated. However, every kind of alchemy in the fairy world is based on the power of the law, and the emphasis is on making the power of the law contained in the treasure stronger in the process of refining. Therefore, the methods of the Immortal Family's alchemy technique, each of which is extremely extraordinary, cannot be done at all in the Nether. ”

"And even if you have the ability to do it, the quality of these materials of yours is not enough! These materials can only refine the magic weapon of the Heavenly Spirit Treasure level, and they are not treasures that can contain the power of the law, so the old man can't teach you the alchemy technique of the Immortal Family to refine the sword!"

"So that's the case!" Li Muran nodded with a wry smile: "It seems that in the eyes of the immortal family figures, the treasure of the heavens is not a commodity that is not in the stream at all, and it is not worthy of using the immortal family's alchemy." ”

"That's true!" Huo Yun said, "The treasure that can be refined with the Immortal Family's alchemy technique is at least the Xuantian Treasure level. Further up are the so-called immortal weapons, immortal treasures, above the immortal treasures, there are rumored to be heavenly weapons, artifacts and other anti-heaven treasures! That kind of treasure, each one is unique, and all contain infinite power, even the old man can't imagine it!"

Li Muran followed Huoyun's words, and his thoughts suddenly drifted to the clouds.

In the Second Realm of Spirits and Demons, he was already in the ranks of the top group of monks, but for the Immortal Family, he was not in the stream at all.

"Since you can't use the immortal technique to refine the Heavenly Sword, the junior has no choice but to use the Nether Technique!" Li Muran sighed lightly, and then began to refine the sword.

He had already had the sword refining technique, which he had obtained in the Heavenly Sword Valley more than a thousand years ago. The old man of Heavenly Sword and several of his disciples can be regarded as extremely profound sword cultivators in the spirit realm, and their sword refining skills are also very skillful, and the methods of sword refining are also diverse.

Li Muran referred to the sword refining technique, combined with his own powerful mana, and complete sword refining materials, and after just half a year, the sword embryo was completed.

Li Muran named this sword "Hui" and placed it in the dantian to continue to cultivate.

In this way, he had the three swords of greed, darkness, and radiance, although these three swords were only treasures of heaven, but they were all of good quality, enough to compete with the natal magic weapons of other early Mahayana monks.

After the Hui Sword was cast, Li Muran continued to practice in this remote place, dripping blood to replenish the heavenly stones and refining talismans.

After a few more years, the strange grass in Li Muran's dantian sprouted a new leaf, and the catastrophe also came as scheduled.

This time, the power of the Heavenly Tribulation has increased significantly, and Li Muran's physical body has reached the extreme, and it has not improved much compared to the last Tribulation, so it is obviously much more difficult than the last time.

However, Xiao Lei Xiu has improved a little, with her help, coupled with the help of Xuantian Ancient Vine, Li Muran also survived this catastrophe unharmed.

"It seems that I want to step up my cultivation progress and enhance my supernatural powers!" Li Muran secretly said in his heart: "Otherwise, this Heavenly Tribulation will be more powerful every time, I'm afraid that in another thousand years, the strength of that Heavenly Tribulation will make me unable to bear it!"
