After Yuan Bo mentioned Mu Jingfan, he watched him enter his thoughts, and then left quietly, without disturbing his thoughts anymore.

One thought after another flashed in Mu Jingfan's mind, since ancient times, the special substance of aura has made many impossible things a reality, so this practice of retaining the will should still be inseparable from aura.

Step by step, Mu Jingfan seemed to feel that he could see, and there were faint fluctuations in the books in his hands, which gradually increased.

What Mu Jingfan didn't know was that his eyes didn't know when they had turned into the most natural pure white of the aura, and the black and white chaotic yin and yang were circulating in his eyes.

He saw that all the books in front of him exuded very different fluctuations, some of which repelled him, while others were extremely close to him.

With this method, Mu Jingfan took out an ancient book from the pile of books, on which were written the four big characters 'Tiangang Furnace'. The whole book shone with a dark red aura, and Mu Jingfan could actually feel a trace of intimacy from it.

At the same time, out of the corner of his eye, he also caught a glimpse of the ancient book that was making abnormal fluctuations on the other side, and after turning the ancient book out of the same way, the three golden words 'Great Cremation' came into his eyes.

"It's decided that it's these two. Holding the two ancient books, Mu Jingfan sat at the desk on the side, flipping through the ancient books.

'Tiangang Furnace' is about a kind of alchemy technique that is extremely demanding for cultivators, in fact, the full name should be called 'Tiangang Furnace Refining Body Decision', but the compiler seems to think that this is more concise.

The reason why it is said to be harsh on cultivators is not because there are any special requirements, on the contrary, there are hardly any special needs other than the limitations of the aura attributes.

Its harshness is aimed at the strength of the cultivator's will, this kind of body refining technique can only be cultivated by the master of the fire attribute aura, treating his body as an embryo, and using the fire attribute aura to build his body into a divine weapon, the pain in this can be imagined.

Mu Jingfan had personally tried the feeling of aura running wild in his body, but this technique was exactly what he required. Perhaps when this method was first created, the creator did not think that many people would choose this way of self-harm to train themselves to have a strong body, so they simply raised the threshold of this method to another level.

"Our degree of chemical master, to obtain the creation of heaven and earth, need to be used as a furnace, with the body of steel, refining the art of thirty-six heavenly gangs, and casting the body of an artifact. ”

Mu Jingfan looked at the ancient book in his hand, his mind was also constantly turning, he knew the pain and danger of this method, but the great increase in strength that it could bring attracted him.

Some images flashed in my mind, Mu Tian sleeping on the hospital bed, the five gods who were still in the dark, and people who were on the verge of death. Mu Jingfan made up his mind, he needed this strength.

Looking at another book, the name of 'Great Cremation' looks like an attack technique, but after reading it, Mu Jingfan realized that this was originally a footwork to suppress the enemy.

According to the author, this footwork was created by an ancestor who observed the scene of the cremation of the ancient people, and in the middle of the battle, through special positions and directions, he overwhelmed the opponent step by step.

Supplemented by the power of the fire attribute aura, it can make the enemy feel like he is in a raging flame, which is exactly what Mu Jingfan needs.

Knowing the truth that greed can't chew too much, Mu Jingfan didn't look for other ancient books, but chose to return to the compound to practice the magic recorded in ancient books.

The introduction of the 'Tiangang Furnace' was a test of the cultivator's will, and Mu Jingfan slowly guided the aura in his body according to the method recorded in the ancient books, slowly flowing through his meridians and flesh.

If there is the slightest negligence in this, he will feel a piercing pain, so he must exert extreme effort to control the aura.

Fortunately, Mu Jingfan was an extremely patient person, and during this period of time that required a high degree of concentration, he did not relax because of boredom, and it was not until he slowly carried out three large weeks that he relaxed and wiped the sweat from his forehead.

At this time, without his guidance, the aura was already operating autonomously in his body, and what he had just done was similar to opening the channels needed for the operation of the aura.

Obviously, his work was not done thoroughly, and the aura in his body rampaged through his meridians, and the severe pain swept through his whole body at once, and the surface of his body began to ooze blood.

This method of forcibly expanding the meridians is not accepted by everyone, because it is likely to lose the origin of the master, so few people have done so for a long time.

Gritting his teeth and persevering, Mu Jingfan's eyes were already bloodshot because of patience, but fortunately, the 'car accident' of the aura seemed to only last for a short time, and it stopped soon after the meridians reached the requirements.

This time, Mu Jingfan was lying on the ground sweating profusely, his body looked extremely terrifying, and the dried blood was densely covered all over his body.

Mu Jingfan also seemed to notice this, and after seeing that there was no special taboo after seeing clearly, Mu Jingfan went back to his room to take a shower and clean the blood stain on his body.

Although his body was not very obvious yet, he could still feel a slight difference from before, which was excellent news for Mu Jingfan.

After the initial entry of the 'Tiangang Furnace', the thirty-six corresponding acupuncture points in the body should be lit up with flame aura, and each acupuncture point will stimulate a trace of power, until all the acupoints are connected into one, and all the power will be completely stimulated.

However, every time the acupuncture point is lit, you need to endure great pain.

Under his deliberate guidance, the aura slowly converged to the three acupoints of Heavenly Storm, Heavenly Cry, and Tianqiao in his legs, like fuel thrown into a furnace, and the aura was ignited in his body in an instant, bursting out with strong energy.

In his body, the three acupuncture points burst out with extremely dazzling light at once, but what followed was not the surge of power, but the burning pain in his body.

The energy from the three acupuncture points scorched his body like a raging fire under the furnace, and his face was distorted by the pain.

Fortunately, this burning sensation did not last long, and with the blessing of the acupuncture point, his right leg felt full of strength, and this improvement was extremely obvious.

Sweating again, Mu Jingfan was about to get up and scrub it, but just as he got up, his body suddenly became unbalanced and fell to the side. The force in his right leg was so great that his body couldn't adapt for a while and he lost his balance.

Mu Jingfan could only carefully drag his right leg and walked back to his room step by step like a lame. After spending an afternoon, Mu Jingfan finally barely adapted to the increased strength of his right leg and was able to walk simply.

However, the 'inch step' has frequently failed due to the imbalance of the body, and if he wants to solve it, Mu Jingfan can at least wait for the three acupoints in his left leg to also light up before he can continue to use it.

Without further ado, Mu Jingfan immediately sat down cross-legged, trying to open the three acupoints of his left leg, but after some attempts, he gave up, his aura was still cultivating the acupoints of his right leg, and he couldn't mobilize it at all.

Now he doesn't want to say 'inch step', even the use of aura has become extremely difficult, no wonder no one in this 'Tiangang Furnace' is willing to cultivate, there are too many restrictions attached to the degree master after this cultivation, and it is completely a set of shackles for himself.

But fortunately, because it was only the initial three acupuncture points, Mu Jingfan didn't have much time to cultivate, only two hours. Moreover, with the progress of the cultivation of the 'Tiangang Furnace', the aura that needs to be cultivated will also become controllable.

By the evening, the three acupoints of Mu Jingfan's right leg had been cultivated, and the energy of flames from the acupoints was constantly stimulated to temper his right leg, and this change seemed to be extremely obvious to his feelings.

At this moment, he was finally able to continue to light up the acupuncture points in his body, sat down cross-legged, and he already had experience, skillfully guiding the aura to pour into the three acupoints of Heavenly Defeat, Heavenly Prison, and Tianhui in his left leg, and the same burning sensation emerged as before.

It was even stronger than before, but Mu Jingfan still gritted his teeth and held back, and the continuous power that emerged from the acupuncture point diluted his feeling of pain.

When everything was over, Mu Jingfan was lying on the floor, and all the aura had already flowed in his left leg to cultivate the acupoints, so he could take this opportunity to rest.

The Mu family's dinner had already started for a long time, Mu Jingfan walked to the uneven table and sat down, eating silently, a day's cultivation had already consumed all the things in his stomach.
