Mu Yiyang and Chang Wei already had an excellent relationship, but now that he accidentally learned that he could only stay in the mountains for the rest of his life, his heart couldn't help but feel heavy, so he stopped talking, but followed Mu Tianfu back to the stone house all the way and began his daily routine fire control training.

The so-called fire control training, to put it bluntly, is actually to train the monk's ability to control the charcoal fire in the furnace, which is a common way for medicine apprentices to improve their ability to control soul power.

According to Mu Tianfu, the pharmacist's ability to control soul power can be roughly divided into four realms: controlling the gods, refining the gods, channeling the gods, and transforming the gods, and each realm can be subdivided into four stages: the early stage, the middle stage, the late stage, and the consummation.

Although the pharmacist's soul power cannot be improved through cultivation, his ability to control it can, so in many cases, the difference in the ability to control the soul power has become a sign of the pharmacist level.

As early as half a year ago, when he learned that he could no longer practice the power of the bloodline, Mu Yiyang put all his thoughts on the training of his soul power control ability. But even so, to this day, he could only maintain the balance of the two furnaces, and he was never able to make the flames of the three furnaces level and enter the threshold of the early stage of the God Control Realm.

"I must succeed today!" Sitting down in front of the small wooden table, looking at the three small stoves that had just been lit in front of him, Mu Yiyang secretly made up his mind, and then closed his eyes.

"Calm your mind and unite your mind!"

Mu Yiyang silently recited the mantra in his heart, and after a while, his breathing stabilized, and he saw a small white vortex composed of soul power in his mind.

"Hold the yuan and guard the soul, turn thoughts into anger!"

Immediately afterwards, Mu Yiyang let out another low cry in his heart, and the speed of the rotation of the soul power vortex increased suddenly, and countless small white air currents in the shape of silk threads suddenly flew out of it as the center, rushing out of Mu Yiyang's Heavenly Spirit Cover, and finally gathered on the flames of the three small furnaces, wrapping them tightly.

At this moment, Mu Yiyang had a feeling of being connected with the three flames, as if as long as his mind moved, the size and shape of the flames would immediately change with his thoughts.

With the continuous infusion of soul power, Mu Yiyang could feel that his control over the flames was still increasing.

After a while, after feeling that the time was ripe, Mu Yiyang no longer exported soul power, but began to urge the white air flow in the furnace, compressing the three flames little by little, until they turned into three flames of the same size, and then slowly withdrew the soul power.

The suppression of soul power became smaller, and the three small flames suddenly began to grow and grow rapidly like grass that had just broken through the ground in the wild, until they finally turned into three flames of the same size, and Mu Yiyang stopped the action of retracting his soul power, kept the flames in this state, and constantly replenished the consumed soul power.

This is the method he has summed up after many failed attempts to save soul power and maintain the balance of flames to the greatest extent.

Prior to this, in order to maintain absolute control over the flames, Mu Yiyang did not withdraw his soul power, but used his soul power to adjust the size of the flames throughout the whole process, so as to maintain the balance of the flames, which led to his inability to continue to maintain the balance of the furnace fire in the later stage of training due to excessive soul power consumption, which caused the gap in the evaporation of the three bowls of cyan liquid to continue to increase, thus causing an irreparable mistake.

However, with the current method, it is completely different. Pressing the furnace fire into the size of a flame, and then using the spontaneous combustion nature of the charcoal fire itself, as long as he can keep the energy of the three soul powers the same when he withdraws back his soul power, then he can also maintain the balance of the flame while the furnace fire continues to grow, and naturally achieves the purpose of saving soul power.

Although this method is simple, it is not easy to operate in practice, Mu Yiyang has also trained many times before, but he always failed to maintain his balance when he withdrew his soul power, breaking the level of the three fireworks, which led to the failure of the training.

Until the past few days, with the increase in the number of attempts, Mu Yiyang finally succeeded in maintaining his balance in the process of recovering his soul power, but he failed because he was overly careful when replenishing his soul power.

"It's just this last step, take your time, you can do it!"

In the stone house, Mu Yiyang opened his eyes at some point, looked at the three bowls of cyan liquid in front of him that began to boil at the same time, revealing a determined gaze, and then closed his eyes again.

And not far from him, under the row of bookshelves, Mu Tianfu, who had been meditating there with his eyes closed, seemed to be aware of it, and slowly opened his eyes, looking at Mu Yiyang's eyes with a little expectation in his eyes.

Then, with a slight wave of his right hand, a white light curtain invisible to the naked eye suddenly spread around the hall where the two of them were, enveloping the entire stone house in it, instantly isolating all sounds from the outside world.

After doing all this, Mu Tianfu glanced at the stone house for another week, and after confirming that there were no factors in the house that could affect Mu Yiyang, he closed his eyes again.

Time passed minute by minute, and soon the two pillars of incense passed, Mu Yiyang was already sweating profusely, and at this time, the cyan liquid in the three bowls had just evaporated.

Then, another pillar of incense passed, the charcoal fire in the furnace began to slowly become smaller, the clothes on Mu Yiyang's back were already soaked with sweat, his mind was faintly swollen and painful, and there was still a quarter of the liquid in the three small bowls.

"Bobobo......"

Because the fire has become smaller, the cyan in the three small bowls is still churning, but the sound is much quieter, and there is a tendency to slowly cool down.

As a last resort, Mu Yiyang had no choice but to forcibly urge the soul power vortex and inject more soul power into the furnace fire, so as to restore the flame to its original state.

The furnace fire became larger, and the evaporation speed of the cyan liquid suddenly accelerated, but there was not much soul power left in Mu Yiyang's mind, and his head was swollen and painful even more, and even his consciousness gradually became blurred.

After another half pillar of incense, the cyan liquid finally only left a shallow layer of the bottom of the bowl, and it seemed that there was another half pillar of incense to evaporate.

But at this moment, a heart-piercing pain suddenly came from Mu Yiyang's mind. He only felt that his eyes were dark, his consciousness was drowsy, and he suddenly lost control of the fire.

The flame in the furnace lost power and soon dimmed. And at the moment when the furnace became smaller, Mu Tianfu on the side suddenly opened his eyes, looked at Mu Yiyang, who was flushed and painful but still persevering, couldn't help but sigh softly, and raised his right hand slightly, about to remove the light curtain.

However, before he could make a move, the charcoal fire that was about to be extinguished in the three small stoves suddenly jumped. His eyes suddenly lit up, and the right hand he had just raised was withdrawn.

Besides, Mu Yiyang, feeling the constant bursts of sharp pain in his mind and the vortex of soul power that did not react at all, he couldn't help but feel helpless in his heart.

"Is this the only way it can be?" In a drowsiness, Mu Yiyang thought so in his heart, and a deep feeling of powerlessness surged into his heart.

"It's been half a year, is it really that hard to become a quasi-pharmacist?"

At this moment, for some reason, Mu Yiyang suddenly remembered Mu Tianfu, the old man who had been by his side since he could remember.

Although Mu Tianfu didn't know what to say, he knew that there was a force that had been chasing after them all these years. In the dark, there seemed to be a big net cast on their heads, just waiting for Mu Tianfu to slack off one day to wipe out the two of them.

The four years in Yunxi Village were the four most comfortable years for them, and they were also the longest time they had settled, but Mu Yiyang knew that the force behind them would be found sooner or later.

At that time, he will hide behind Mu Tianfu all the way in fear all the way as in those previous moments, silently watching him fight bloodily, but he can't help anything, and he doesn't even have the ability to treat his wounds, and he is useless except to drag his feet.

"No! I can't just give up, I'm fed up with those days when I'm useless and can't do anything! I must succeed this time, and I must not drag Fauber back again!"

"My heart palace has been abolished, if I can't even use my soul power, what is the difference between it and a wasted person, what is the meaning of such a life! I'd rather not!"

"Chang Chen and Chang Wei have stepped into the mortal realm one after another, I have fallen too far behind, if I don't catch up, I may really not be able to catch up!"

......

Mu Yiyang kept roaring in his heart, clenching the root, enduring the severe pain, and frantically urging the soul power vortex in his mind, the soul power vortex that was originally motionless actually reacted at this moment, and burst out with an incomparably strong white light.

At the same time, countless thread-like white air currents suddenly shot out from it, rushed out of Mu Yiyang's Heavenly Spirit Cover, and fell into the three small furnaces, and the charcoal fire that was about to be extinguished suddenly burst into flames, and even the cyan liquid also boiled violently.

One, two, three......

Under the scorching heat, the cyan liquid in the three small bowls evaporated at an accelerated rate, and soon disappeared completely, and at this moment, less than thirty breaths had passed.

"It worked!"

Mu Yiyang had only barely relied on willpower to support him before, but when he saw that the cyan liquid in the three small bowls had evaporated at the same time, he was overjoyed, so he couldn't hold on anymore and fell down.

Beside him, Mu Tianfu had been paying attention to Mu Yiyang's state, and when he saw that Mu Yiyang was about to fall, he stepped forward and helped him.
