"Hey, what is this?"

In the Mujia Medical Hall at night, Mu Yi looked at a corner of the medical hall with a surprised face, and there was a pile of stones piled up.

"Haha, this is a stone I found in a cave in the mountains when I was collecting medicine, and I found that this stone contains soul power, so I got some back." Mu Zhong said with a smile.

"Grandpa Zhong, can you give me some." Mu Yi smiled, his eyes flashing with excitement.

"If you want it, just take it." Mu Zhong said with a smile. Although these stones contained soul power, they were of no use to him.

"Hmm!" Mu Yi nodded, reached out and grabbed a handful of stones, and then went into the house to sleep.

In the room, Mu Yi sat cross-legged and did not sleep. To be honest, he hadn't slept since he awakened the martial spirit.

He now spends every moment of his cultivation and doesn't waste time sleeping.

"I didn't expect that there are things like spirit stones in this world, but the people in this world don't know how to use these things." Mu Yi looked at the stone in his hand and muttered to himself, his eyes full of excitement.

The spirit stone that contains the aura of heaven and earth is too useful for cultivators.

Spirit stones can not only be used for cultivation and mana recovery, but also are necessary for arranging formations.

"Haha, with these stones that conceal soul power, I will definitely be able to quickly improve my cultivation." Mu Yi was excited, and then put the stone away.

Putting the stone away, Mu Yi looked at his hand again.

The wound that had been cut by Grandpa Zhong before was now intact and there was no trace of it.

"Immortal martial spirit, how can it be exactly the same as the legendary immortal physique!" Mu Yi was puzzled.

Although the Xiuzhen civilization is completely different from the Douluo Continent Martial Spirit civilization, it also has many similarities. For example, both cultivators and soul masters have to absorb the energy of heaven and earth to cultivate, and the immortal martial soul that appears now makes Mu Yi think of a kind of physique that is legendary in the cultivation realm.

A cultivator with this kind of physique, who has been seriously injured, can recover as long as he does not die, which is the same as the immortal martial spirit.

"I don't know if it's the will of heaven, the life and death refining formula I got in that demon cave in my last life, the life and death refining formula requires this kind of physique to cultivate." Mu Yi was thoughtful.

The ontological martial soul of this world was not mentioned at all in the novel Dou Yi, but there was a powerful sect of ontological martial soul in Dou Er, the Ontology Sect.

But what Mu Yi didn't expect was that before the Ontology Sect came out, the Ontology Martial Soul would be reduced to a waste Martial Soul, which really made Mu Yi speechless.

Not to mention anything else, it can make people recover no matter how many traumas they have suffered, just by virtue of this, this immortal martial soul is also incredibly powerful, but in Douluo Continent, such a powerful martial soul has been reduced to a useless waste martial soul.

However, there is no way to do this, there is no martial arts to cultivate the flesh in the Douluo Continent, and all the strength of the soul master depends on the strength of the martial soul.

Among them, the beast martial soul can make the martial artist burst out with powerful combat power, and the weapon martial soul can assist the soul master in cultivation, and the ontological martial soul is really useless except for making a certain part of the soul master's body different from ordinary people.

It is no wonder that the ontological martial soul was designated as a waste martial soul in the Douluo Continent.

Although the master always said in the novel that there is no waste martial soul, only a waste soul master, but in fact, in the Douluo Continent, the waste martial soul soul master is not to mention becoming a titled Douluo, even becoming a soul master is a luxury.

"Haha... Look, I want the people of this world to see how powerful the ontological martial soul is. ”

Others classify the ontological martial soul as a waste martial soul, but Mu Yi is like a treasure.

Although Mu Yi was the master of cultivating the way of qi in his previous life, he had also been in contact with refining the body, but because the aura of the earth was depleted at that time, he did not dare to cultivate deeply.

And this world is rich in heaven and earth, and Mu Yi naturally will not miss the cultivation of the refining body.

You must know that in the cultivation civilization, the strength of the body refiner is not lost to the qi refiner at all. In ancient times on earth, many powers of physical sanctification were also born.

It just so happened that he was in that demon cave back then, and not only got the exploding treasure chest, but also got a technique.

That exercise is called 'Life and Death Refining Technique', and it is an exercise that can only be cultivated by people who need the immortal system. Although Mu Yi had only seen it at the beginning, he was already attracted by this exercise.

Although the Yin and Yang Refining Body Technique had been destroyed at the time of the explosion, the exercises had been memorized in Mu Yi's mind word for word, and he had not forgotten it.

"Okay, let me try to cultivate and see if this immortal martial soul can cultivate life and death." Without hesitation, Mu Yi couldn't wait to start practicing this exercise.

Mu Yi closed his eyes and began to cultivate.

Although Mu Yi was the main cultivator of Qi in his previous life, he had also studied the refining body.

Different from Qi refining, body refining is divided into internal and external strength. The so-called internal strength is the cultivation of true qi, that is, internal strength, and external strength is martial arts moves.

It is often easy to practice external skills in refining the body, but it is difficult to achieve internal skills. Unlike the soul master of this world, who has soul power as soon as he awakens his martial soul, it takes decades of hard work to cultivate his internal strength. As soon as the internal force is achieved, even an ordinary palm can burst out with earth-shattering power.

However, Mu Yi's cultivation of life and death is different from the martial arts exercises that Mu Yi has been exposed to, this exercise does not practice any internal and external skills, but only cultivates the physical body.

And the method of cultivation is also very simple, that is, not only to temper the physical body, but also to make the physical body surpass the limit again and again and become stronger.

And how to temper the physical body, you can use external forces to temper it, or you can use exercises to temper it.

The so-called exercise tempering means that this method of refining the body of life and death does not have any words, only a variety of postures, and these postures are methods for refining various parts of the physical body.

Mu Yi didn't think much about it, he tried the simplest posture of life and death refining technique. This pose can temper the muscles of the whole body.

I saw Mu Yi's body in a strange posture, this posture looked the same as the cultivator's breathing in the aura of heaven and earth, they were all sitting cross-legged, but if they looked closely, they were different, but they were very different.

As soon as this posture was completed, Mu Yi only felt that every inch of muscle in his body was writhing.

"Ahh Mu Yi let out a painful wail and immediately stopped this action.

But it was just this moment of effort, Mu Yi was already sweating in pain, and he almost fainted in pain.

"Huh!"

But just when Mu Yi had palpitations, he felt a warm current erupt from his body, which made his originally aching body feel comfortable.

Mu Yi could also clearly feel that his muscles were a little stronger than before.

"Wow! I see, no wonder cultivating this exercise requires an immortal physique. Mu Yi suddenly realized.

This life and death refining technique is said to be a body refining exercise, but it is better to say that it is a masochistic exercise. If you don't have an immortal physique, if you practice this exercise, you will be killed alive.

"Forget it, let's still cultivate in the future!"

After thinking about it, Mu Yi decided not to practice for the time being, this kind of exercise is really worse than death when cultivated.

Although he did not cultivate the technique of life and death, Mu Yi did not plan to rest, but continued to breathe in the energy of heaven and earth.

Mu Yi's main cultivation now is the Cyclone Martial Soul, and he wants to cultivate the Cyclone Martial Soul to the same soul power as the Tianmu Martial Soul as soon as possible.

In the Soul Beast Mountain Range, Mu Yi had already cultivated the Cyclone Martial Soul to the first level, although it was far from the tenth level of the Tianmu Martial Soul, but Mu Yi believed that as long as he worked hard, sooner or later he would be able to cultivate the Cyclone Martial Soul to the same level as the Tianmu Martial Soul.

He didn't want to wait for Tian Mu Martial Soul to become stronger, and then cultivate the Cyclone Martial Soul in turn.

"Little Hou Ye is really working hard, it's a pity that his martial soul..."Outside the window, Mu Zhong saw Mu Yi's non-stop meditation and cultivation, and he was both appreciative and pity.

In his opinion, although Mu Yi is a twin martial soul that is rare in a hundred years, whether it is an immortal martial soul or a Tianmu martial soul, it is a waste martial soul. In this way, even if Mu Yi is working hard, his achievements in this life are limited.

If you want to cultivate to Soul Venerable in your lifetime, it is simply impossible to do it.

"Hey, I hope that the old Hou Yeji people have their own natural appearance, come back soon!"

Mu Zhong was worried about the current situation of the Mu family. After watching Mu Yi's cultivation for a while, he went back to his room to rest.

Although he had the heart to help Mu Yi, he was just a medical soul master, and he couldn't help Mu Yi much at all.

"Hehe..."

Waiting for Mu Zhong to leave, Mu Yi smiled slightly in the room.

Mu Zhong is one of the few people in the Mu family who really cares about him, and Mu Yi also respects this kind old man, but he will not talk to him about his affairs.

Mu Yi closed his eyes and continued to cultivate.
