Mu Feng felt strange that since he got the iron card, the runes in his palm fell silent again.

Fortunately, Mu Feng was used to this, so he didn't pay too much attention to it, he thought in his heart that one day he would solve the mystery of the runes, but it might not be now.

In the blink of an eye, half a year has passed, and Mu Feng's own cultivation has also achieved extremely good results. With the help of Devouring Heart Inflammation, he could clearly feel that his cultivation and Liliang had made a lot of progress.

However, the martial arts realm is still in the middle of the body refining realm, and he has not been promoted for a long time, which makes him feel a little helpless.

Mu Chengzhi and his wife were also a little anxious, worried that Mu Feng's martial arts talent would disappear. However, this kind of worry is useless, it can't help Mu Feng at all, the only thing he can do is to provide Mu Feng with some elixir, but this is far from enough for Mu Feng's high-intensity cultivation.

Mu Feng could only rely on the medical knowledge of his previous life to find some ordinary herbs and soak his body for a simple recovery.

Although he was a little anxious, Mu Feng still didn't deliberately pursue a breakthrough. He could feel that although his cultivation had not improved, his strength was improving every day.

As for the breakthrough of cultivation, it is only a matter of time.

After finishing the day's cultivation as usual, Mu Feng lay on the bed early and prepared to rest, devouring the heart flame as always, refining his bones and meridians.

But soon Mu Feng sensed that something was wrong today. I don't know Weishenme, but the burning pain from my body is more than ten times that of normal times.

The scorching air flow penetrated into the bones and meridians, scorching every bone and muscle. Mu Feng could even hear a faint burning sound coming from within his own bones.

The boy's dark face turned unusually red, and his whole body emitted white heat that could be seen with the naked eye, and the slight burning sound was particularly loud in the quiet of the night.

Mu Feng bit his lip tightly, enduring the incomparably severe pain, his eyes were a little blood-red from this sharp pain and burning, and his whole body trembled slightly.

"Ahh

Finally couldn't bear it anymore, Mu Feng yelled, hurriedly rushed out of the room, and jumped into the big water tank in the kitchen.

"Whew!"

Mu Feng exhaled a long breath, because the coolness brought by the clear water also relieved the sharp pain and burning for a while, but in an instant, this refreshing feeling was driven away by the sharp pain and burning heat.

Mu Chengzhi and his wife, who lived next door, rushed over when they heard the sound and saw the scene in the kitchen, and they were also stunned for a while.

After Mu Feng jumped into the water tank, the clear water in the water tank boiled in a short instant, and a large cloud of white gas diffused from the water tank, and Mu Feng was tightly wrapped in these white gases, and he couldn't see the specific appearance, but from the moans that came from it, he could hear that he was suffering from severe pain.

Lin Hui anxiously rushed towards Mu Feng, wanting to know what was going on, but was stopped by Mu Chengzhi.

"Brother Zhi, what's wrong with Feng'er?" Lin Hui looked back at Mu Chengzhi and said in a state of confusion.

Mu Chengzhi was also anxious, he didn't know what was going on with Mu Feng, but his intuition told him that if he interrupted rashly, the result might get worse, and he spit out four words with difficulty: "Wait and see." ”

The two stood by the water tank, quietly looking at Mu Feng, who was surrounded by white gas. And the moaning sound from Mu Feng gradually lowered, as if the pain had been alleviated, which also made Mu Chengzhi and his wife's hearts relax a lot.

At this time, Mu Feng felt that the burned bones and meridians had become extremely tough, and after the severe pain, it was an extremely comfortable feeling. A warm current of heat flowed around him, and a sensation that had never been felt before hit the nerves of his brain.

This strange scene lasted for about half an hour, the white gas gradually dissipated, only to hear a "plop" sound, Mu Feng climbed out of the water tank and fell to the side.

Mu Chengzhi and his wife hurriedly ran over and helped Mu Feng up.

I saw that Mu Feng's face was a little pale, and his whole body seemed to be out of strength, like a puddle of soft mud falling into Mu Chengzhi's arms, his whole body was almost naked, and his slightly dark skin was stained with sticky black objects, emitting bursts of foul smell, and the water tank behind him was even more stinky.

"Refining bones and washing marrow, opening tendons and arteries!" Mu Chengzhi looked at this scene and couldn't help but exclaim!

"Brother Zhi, Feng'er, he has already broken through to the mid-stage Great Perfection of the Body Refining Realm!" Lin Hui said in surprise.

"Well, oh my God, I Mu Chengzhi gave birth to a genius son. Mu Chengzhi swept away his usual seriousness, and his face was full of ecstasy.

Mu Chengzhi's ecstasy is reasonable, in just nine months, from the early stage of the body refining realm to the middle stage of the body refining realm, this is something that has never happened in Mu Chengzhi's memory, but his son has done all this.

However, in addition to being happy, he was also a little worried that Mu Feng's foundation was unstable. But when he probed Mu Feng's physical condition, he found that the toughness of Mu Feng's bones and the breadth of his meridians were much stronger than those of a teenager of the same level.

"Dad, mother. Mu Feng looked at the overjoyed Mu Chengzhi and his wife, and his vision gradually blurred......

The next day, Mu Feng woke up in the soft sunlight, feeling that his body had an unprecedented lightness, and this lightness hid a strong liliang.

The strength that had not risen for half a year finally broke out again, which made Mu Feng also breathe a sigh of relief.

His worries were completely superfluous, normally speaking, it was extremely common to stay in the middle of the Body Refining Realm for a year, after all, the Body Refining Realm was a realm that laid the foundation of martial arts, and it took a long process.

However, Mu Feng had a devouring heart flame forging body, which greatly reduced this long process.

He jumped out of bed, got dressed, stretched his muscles, and came to the courtyard.

In the courtyard, a thin and tall figure stood there, like a pine.

"Daddy. Mu Feng called out respectfully.

"What happened last night?" Mu Chengzhi turned his head, looked at Mu Feng, and asked seriously.

Mu Feng didn't know how to explain, so he could only put on an innocent expression and said, "Dad, I don't know either, it's just that I suddenly felt a burst of pain and heat in my abdomen last night, and you have already seen the rest of the things." ”

Seeing that his son looked innocent, Mu Chengzhi stretched out his hand and sent out a mysterious force to probe Mu Feng's body, and indeed found nothing unusual. With the strength of his Qi Transformation Realm, it was impossible to discover the abnormalities in Mu Feng's body.

After not finding anything, Mu Chengzhi took out a worn-out booklet from his arms and handed it to Mu Feng, saying, "This heart refining recipe is just right for you to practice now, if you don't understand something, come and ask me." ”

"Got it, Dad. Mu Feng answered while taking the booklet, only to see that the cover was slightly yellowed, and the cursive script of three dragons flying and phoenixes dancing came into view: Refining the Heart.

After reaching the mid-stage Great Perfection of the Body Refining Realm, you have completed the strengthening of your skin, bones, and meridians, and then you will focus on cultivating your viscera, qi, blood, and acupuncture points. This heart refining recipe was specially made for martial artists to cultivate viscera, qi and blood, and acupuncture points, which was undoubtedly a timely rain for Mu Feng.

Mu Feng couldn't wait to open it and read it carefully, only to see that the beginning of the book reads: Cultivate one way, quench the skin and bones, then open the meridians, and finally refine the painstaking efforts, so as to stimulate the qi......

In the realm of refining the body, cultivating the viscera, qi and blood, and acupuncture points is the key to whether or not the Xuan Li can be stimulated, because only when the fragile viscera, qi and blood, and acupuncture points are strengthened, can they adapt to the strong and horizontal energy impact of the Xuan Li.

Mu Feng gradually immersed himself in the heart refining technique......
