Chapter 151 Demon Fire Refining Yuan

  The magic fire refining element is mainly divided into three stages, corresponding to the initial, middle and late stages of each realm.

   At the beginning, middle and peak of each stage, mana must be tempered once. There are a total of nine times in each realm. When the nine times are completed, the mana will be at the peak of this realm, and the mana will be about 20% purer than that of a monk of the same level.

However, the magic fire refining element also has certain requirements for the power of the flame. At present, the Qingyang magic fire is enough to complete the quenching in the initial stage of foundation building, but if the training is too fast, you need to find a way to increase the power of the flame to effectively quench it. Refinement of mana.

"it's time."

   Liu Yu's thoughts moved, and the light blue flame in the dantian jumped suddenly, and the flame was even better than three points.

   Then, the flames slowly fell towards the lake of mana, and the distance between the two slowly narrowed.

   Maybe it was a breath or two, or maybe it was longer, the flames and the lake finally began to touch.

   As soon as the two came into contact, the light blue flame spread to the entire lake, covering the surface of the lake in a short while, turning it into a sea of ​​blue fire, and then it began to burn roaringly.

   Gradually, the lake of mana began to roll and boil, and small bubbles appeared.

   Beads of sweat grew on Liu Yu's forehead, dripping on the front of his clothes, wetting them.

The peaceful expression on   's face no longer exists, instead, because of the pain, it becomes distorted and ferocious, looking shocking.

  Although the pain in the dantian and the flesh body is not comparable to that of the primordial spirit, it has to be completely overcome by gritted teeth, and there are no spiritual things that can be relieved.

   "Ugh"

   Liu Yu couldn't help but let out a scream, and then clenched his teeth hard to hold back.

   He knew that it was the critical moment to temper his mana, and if he didn't pay attention, he might lose all his efforts and his cultivation would suffer greatly.

  Because of the extreme pain, even his hands were trembling, but Liu Yu still slowly and firmly grasped the special magic.

   He closely guards the clarity of his mind, restrains his mind, and at the same time carefully controls the Qingyang Demonic Fire, which is in close contact with mana, so as not to cause damage to his dantian.

  Under the flaming light blue flame, the lake of mana kept boiling to a certain extent, and it did not continue to intensify, nor did it tend to subside.

   Bubbles popped out and burst, and wisps of untraceable black smoke evaporated, which was the impurities in the mana.

  Because Liu Yu takes a lot more medicinal pills than the average monk, although he usually pays attention to polishing his mana, the impurities in the mana are still much more than other monks.

   If you cultivate to the peak of the late stage of foundation establishment, because the mana is not pure enough and there are too many impurities, the possibility of condensing golden elixir is extremely low.

  These impurities are hidden so deeply that Liu Yu can't find it when he looks inward, because he has already been integrated with the mana, and it is impossible to remove them by ordinary means, unless he takes rare heaven and earth spirits or rehabilitates them.

   But at this time, under the tempering of the Qingyang Demonic Fire, it was slowly discharged and dissipated, and a part of the cultivation base mana was dissipated along with it.

   I don’t know how long it took, maybe a day or two, maybe longer.

  The boiling of the lake of mana slowly subsided, and the sea of ​​​​fire gradually shrank.

   The light blue flames slowly gathered into a ball again, and then the two slowly separated, and the Qingyang Demonic Fire rose above the lake of mana again, occupying the center of the dantian.

   The light cyan Lake of Mana was significantly smaller than before, but it was more crystal clear, like the finest jade, exuding light cyan brilliance.

  With the completion of the mana tempering, Liu Yu's expression gradually calmed down, and his hands stopped laying the magic formula on his knees.

   He did not end the exercise right away, but was still slowly exercising and adjusting his breath.

   At a certain moment, Liu Yu suddenly opened his eyes, and the light in his eyes flashed away.

   "Poof"

   As a mouthful of pitch-black blood was spit out, Liu Yu's cultivation aura suddenly declined by a small amount, but it became more solid, and the spiritual pressure throughout his body increased instead of falling.

"Hahaha!"

   Feeling the purer and purer mana in his dantian, although Liu Yu's face was as pale as paper, he couldn't help laughing loudly, revealing a morbid smile.

  There are many benefits of pure mana. Whether it is to release spells or to drive magical instruments, the power is stronger than before. Although the total amount of mana is now reduced, the overall strength does not drop but rises.

   But the side effects of taking medicine pills for a long time are more than that. There is also a lot of erysipelas accumulated in the flesh. The magic fire refining can only refine the mana and remove some impurities in the mana, but it can't do anything about the erysipelas in the flesh.

  Liu Yu slowly stopped the work and sat cross-legged on the futon, a thought flashed in his eyes.

   As for erysipelas, he really doesn't have a good way right now, there is no corresponding secret technique to remove erysipelas, and there is no spiritual thing that can wash the body to remove erysipelas, and there is no news about this.

   "You can only think about it in the long run."

   Liu Yu quickly regained his thoughts. Although erysipelas would affect the formation of pills, he was only in the early stage of foundation building, and he still had more than 100 years to prepare.

   For cultivators in the Foundation Establishment period, whose lifespan is generally around 240 years, before the age of 180, they belong to the prime of life.

  Only after the age of 180, at the age of 200, the physical body will age rapidly, the essence will flow away rapidly, and the possibility of forming elixir will be lower and lower.

  Liu Yu calculated with his fingers, the process of tempering mana lasted for 14 days, and he would be on duty tomorrow, and it was his turn to go to the ground to defend.

  Suddenly, a strong odor entered his nose. Liu Yu noticed that his body was covered with a layer of gray-black material, and there was still a lot of sweat stuck on the surface. The clothes were wet, and the stickiness was very uncomfortable.

   He got up quickly, went outside to wash his body up and down carefully, and put on a black robe with a hood.

   Liu Yu did not go back to the practice room, but went to lie down on the Taishi chair in the living room, took out the storage bag to store the magic method, and continued to comprehend the foundation-building chapter.

   A day later, Liu Yu left the cave at the right time, closed the formation and followed the stairs he came to to the entrance of the Spirit Medicine Garden.

When he rushed to the top, Yan Hongyu, Ding Hui, and Cao Mengyu's three daughters were already here, and they were gathering together and chatting in a low voice. More than a dozen disciples of the Qi refining period stood in three rows not far away, also whispering. .

   Divine Sense swept around, but did not find the figures of the other three fellows of the Foundation Establishment period, presumably they had already returned to the cave to rest.

   "I'm one step late because of the practice, I hope the three senior sisters don't take offense."

  Liu Yu walked into the three girls, cupped their hands and clasped their fists in greeting.

   "It's all right, it's just that I waited one step ahead, and Junior Brother Liu arrived at the stipulated time, so don't worry about the little things."

   Cao Mengyu's eyes flashed strangely, and he responded with a smile like a flower.

   Yan Hongyu and Ding Hui looked as usual and greeted politely.

  Liu Yu noticed Cao Mengyu's fleeting expression, and his heart moved.

After three years of rapid improvement in taking medicinal pills, his cultivation base has left the category of newly promoted foundation building and has reached the level of a normal foundation building cultivator. At the point of new foundation building.

   After going through the magic fire to refine the essence, his cultivation base has returned to the level of the new foundation building, and there is no need to use the hidden spirit technique, so he did not use the hidden spirit technique at this time.

   "What a keen sense!"

The    cultivation level has risen and fallen, although it has remained at the level of the newly promoted foundation, but there has always been a slight change.

   It's just that this kind of change is very small. Even Yan Hongyu, who was in the late stage of foundation building, didn't notice it. Unexpectedly, it was noticed by Cao Mengyu, who was in the early stage of foundation building.
