Late at night, the cool moonlight sprinkled on the earth, and the entire Red Maple Town had fallen into a deep sleep.

Mu family, the young Mu Feng was lying on the bed, trembling violently, and his face showed pain.

After practicing willow boxing all day today, Mu Feng also felt extremely tired, and after soaking his tired body in cheap herbal soup, he lay down on the bed and prepared to rest.

Unexpectedly, the devouring heart flame at the dantian was like a violent beast, spreading to every bone and every meridian in Mu Feng's body, and bursts of burning pain spread from the abdomen to the whole body, and the whole person felt as if he was being scorched by fire.

However, Mu Feng also learned from Qingfeng Tianzun's mouth that Devouring Heart Flame was of great help to his current cultivation. This should be the legendary bone refining and marrow washing, opening tendon arteries.

Worried about waking up Mu Chengzhi and his wife next door, Mu Feng gritted his teeth and endured it tightly, beads of sweat the size of soybeans covered his forehead, and the sweat pores of his whole body were full of heat.

The small room was filled with this heat for a while, and the temperature of the whole room also increased a lot, as if it had returned to the hot summer from the cool late autumn.

In addition to refining bones and washing the marrow and opening the tendons and arteries, phagophagocarditis also contains a kind of phagophagotic power. Of course, the current Mu Feng is still unable to use this devouring power, and he can't even skillfully control this Heaven and Earth Flame.

This situation lasted all night, Mu Feng endured the pain, couldn't resist the invasion of drowsiness, and fell asleep in a daze.

When he woke up in the morning, he was surprised that Devouring Heart Inflammation, who had been working all night, seemed to have a spiritual wisdom, and returned to the dantian, as if he was asleep, and there was no movement at all.

What made him depressed was that he was sweating profusely, and there was some black sticky material attached to his skin. The stench of the gooey is disgusting.

Mu Feng didn't know that Devouring Heart Inflammation was a strange flame between heaven and earth, with a certain amount of spiritual intelligence, and after being branded with the seal of essence blood by Mu Feng, he recognized him as the master and automatically helped him refine his bones and marrow and open his tendons and arteries. In other words, even if he doesn't do anything, Devouring Heart Inflammation will strengthen his muscles and bones.

However, Mu Feng's muscles and bones are too delicate, and this kind of bone refining and marrow washing and opening tendon arteries can only be carried out little by little.

Mu Feng smiled bitterly, flushed himself with a basin of water, and then went to the courtyard to practice willow boxing.

When he let go of his hands and feet to cast a willow fist, he suddenly felt an unprecedented lightness in his body, his fist technique was also extremely smooth, and his body was not as stiff and rigid as yesterday.

After a set of boxing techniques, the body did not feel any fatigue, but made Mu Feng feel extremely comfortable and refreshing.

He guessed that it was the result of devouring the heart inflammation body last night. Only then did he truly feel what a great creation Qingfeng Tianzun had sent to him.

For a few days, Mu Feng practiced willow boxing during the day, and at night he allowed the devouring heart inflammation to refine his body.

In just a few days, he could clearly feel some changes in his body, including the level of comprehension of Willow Fist.

The only thing that bothered him was that every morning he had to make a basin of water to wash away the black, disgusting sticky stuff on his body.

Mu Chengzhi was also shocked by Mu Feng's change, he didn't expect that in just a few days, Mu Feng would be able to cultivate the Willow Fist to such a point.

Although the willow-shaped fist seems simple, it is still extremely difficult to really overcome the rigidity with softness and unload the force with homeopathy, but looking at the willow-shaped fist made by Mu Feng, I have already comprehended seven or eight times out of ten.

At this time, Mu Feng also considered another thing in his heart: actual combat experience.

Although Mu Feng has now cultivated martial arts, he has no experience in fighting against others at all.

Fighting with Mu Chengzhi in the past few days can only be called a competition, and it can't increase his actual combat experience, so he set his sights on the Luoxia Mountain Range.

Although there are many demon beasts in the depths of the Luoxia Mountain Range, they are just ordinary beasts on the periphery, which is just suitable for Mu Feng to experience. Although those fierce beasts were similar in size and size to demon beasts, their combat effectiveness was much worse than that of demon beasts. With Mu Feng's current cultivation, it is more than enough to deal with some lone beasts.

Therefore, Mu Feng entered the periphery of the Luoxia Mountain Range and specifically looked for some lone beasts to fight. Of course, this is also done without Mu Chengzhi and his wife, if Mu Chengzhi knows, he must be reprimanded.

At first, Mu Feng was still a little scared, after all, he was facing a ruthless beast, and if he was not careful, he might become a delicacy in the mouth of the beast.

But after killing several fierce beasts, Mu Feng's confidence increased greatly, and he was even more unstoppable, and he became a little fond of this kind of fighting, and even felt a little numb to blood. For a moment, the beasts on the periphery of the mountain range all had a feeling of wind and noise,

On the periphery of the Luoxia Mountain Range, Mu Fengpan was sitting under a big tree, resting with his eyes closed. On his body, there was a lot of shocking blood, and the rich smell of blood emanated from it.

Next to Mu Feng, there was a mountain boar that had been dead for a long time, the mountain boar was huge, compared to Mu Feng, it was like a small mountain, but there was an obvious depression in its head, and it was obviously killed by someone punching the skull.

In the life-and-death struggle with these fierce beasts, Mu Feng also completely understood what it means to overcome rigidity with softness, and bring rigidity with softness.

Willow-shaped boxing, although it is intended to overcome rigidity with softness, also needs to be soft with rigidity. The so-called rigidity is the sudden force after the softness, the fist is light and heavy, and it is free to retract and release.

When he killed the boar just now, Mu Feng exhausted the boar's physical strength with his soft strength, and then slammed the boar's skull with his strength, killing it under his own punch.

After Mu Feng carefully experienced the fight just now, his heart moved, and a black flame suddenly appeared on the palm of his hand, and this was the Heaven and Earth Strange Flame Devouring Heart Flame that Qingfeng Tianzun gave him.

Qingfeng Tianzun told Mu Feng not to reveal the Devouring Heart Flame in front of outsiders, but on the periphery of this deserted Luoxia Mountain Range, he still summoned the Devouring Heart Flame, firstly, to prevent the sudden attack of fierce beasts, and secondly, to explore the art of fire control.

Although he was now able to control the Devouring Heart Inflammation with his mind, Mu Feng still felt extremely rusty. If there is a fire manipulation technique, I believe that Devouring Heart Flame can become one of your hole cards. But after practicing for a long time, Mu Feng has only found a little bit of a doorway, and he can control the Devouring Heart Inflammation to carry out some simple attacks.

Although the Devouring Heart Flame looked plain on the surface, Mu Feng could still feel its power. If it weren't for Mu Feng's essence blood brand, it would definitely be incinerated into nothingness in an instant.

Mu Feng used his consciousness to manipulate the Devouring Heart Flame, making it transform into various forms, which he discovered by accident, and felt extremely interesting.

Devouring Heart Flame, this kind of Heaven and Earth Flame was taken by Mu Feng to play at will, if he let the Black Flame Evil Venerable in the Gangfeng Sealing Demon Array see it, he would definitely be so angry that he vomited blood.

However, Mu Feng also knew that it was extremely difficult to really control the Devouring Heart Flame, and he had seen the Black Flame Evil Venerable manipulate the Devouring Heart Flame in the cave, and the power he displayed moved the heavens and the earth.

The current Mu Feng can only divide the Devouring Heart Flame into two paths and control them separately, to be like the Black Flame Evil Venerable, he can turn the Devouring Heart Flame into tens of thousands, and control it as he wishes, he still needs to go through an extremely long cultivation path.
