"Maybe it's because ...... When the spiritual energy of heaven and earth on the spiritual wood is transmitted into the body, supplemented by the 'pounding' of the wooden pestle and the 'collision' of the stone bag, it drives the vibration of the muscles, flesh and blood, and further promotes ......the completion of the marrow washing.

In an instant, many thoughts and thoughts flashed through Fang Yi's mind, and in the end, all the thoughts and thoughts were summarized clearly.

"The teacher is now using the 'Thunder Sound Tiger Leopard' to oscillate the internal breath into the internal organs and even the bones, so as to impact the great innate nature of the marrow washing, and this wooden pestle deep pounding and stone bag impact is actually another kind of 'Thunder Sound Tiger Leopard'? However, the heaven and earth aura in the spirit wood was injected from outside the body, so it was able to achieve the same effect as the 'Thunder Sound Tiger Leopard' with a relatively simple external force. ”

Fang Yi's eyes gradually lit up.

"In this case, in fact, the external impact should be as important as the 'Thunder Sound Tiger and Leopard'? If we can grasp the frequency of the severity, will we be able to speed up the process of marrow washing?"

As soon as this idea appeared, Fang Yi couldn't stop and immediately experimented.

Closing his eyes, the stone bag hit his chest again, this time, Fang Yi was not only concerned about the trace of heaven and earth aura that was transmitted into his body from it, but also on the stone bag that hit his chest.

The high concentration of the mind made time seem to slow down a lot, and Fang Yi keenly felt that the moment the stone bag hit his chest, a concussive force shook from the skin to the muscles, from the muscles to the membranes, and from the membranes to the bones. This shock is decreasing in layers, and by the time it reaches the bone, it is already imperceptible.

And I don't know if it's a coincidence, Fang Yi found that when the bone was shaken, that trace of heaven and earth aura also happened to be transmitted to the bone, and at the moment of oscillation, it entered the bone crack.

Fang Yi pushed the stone bag again, tried it five times in a row, and finally affirmed the conjecture in his heart, it was not a coincidence, but a fit in the dark.

Then, Fang Yi directly put his hand on the stone bag and transported the "Yuan Sucking Great Demon Wheel", and a trace of heaven and earth aura was forcibly extracted from the sawdust of the stone bag and flowed into his body. Fang Yi controlled these spiritual qi to seep into the cracks of the bones, and found that it was far inferior to the absorption effect after the shock generated by the stone bag just now.

At this time, Fang Yi finally determined that the reason why the Heaven and Earth Spiritual Qi was able to enter the bone crevice so smoothly was that the shock generated by the stone bag played a very key role, and this effect was like the "Thunder Sound Tiger Leopard".

Then Fang Yi began to gradually increase the intensity of the stone bag's blow, paying attention to the absorption efficiency of the heaven and earth aura to determine the best strength and frequency.

This kind of test was very subtle, and under Fang Yi's precise control, the increase in the striking force of the stone bag was refined to two.

After three hours, after countless repeated attempts, Fang Yi finally determined the best strike force and frequency, under such strength and frequency, the efficiency of the Heaven and Earth Spiritual Qi being absorbed by the bone seams was the fastest, it was almost twice as fast as at the beginning.

In other words, after figuring out this trick, Fang Yi's cultivation progress immediately accelerated by two times, which is not a small gain!

At this cultivation speed, it took Fang Yi three hours to finally completely absorb the heaven and earth aura contained in the sawdust in the stone bag.

Based on this, Fang Yi calculated that the Wen Nanmu that he had worked hard to obtain weighing more than a thousand catties could support him to absorb it for about three hundred hours in a row, which was equivalent to thirteen days. If you absorb the same amount every day, you should be able to sustain your practice for more than three months.

"Washing the marrow is a time-consuming and laborious process, it seems that my cultivation can't improve by leaps and bounds like before, but I don't know if this thousand catties of Wen Nanmu is enough?"

When Fang Yi walked out of the practice room, it was already dawn, and a new day had begun.

Everyone gathered, and after breakfast, Zheng Shuang called Fang Yi: "Senior brother, I want to ask you about Wing Chun." ”

"Yes, I can't wait now, I really didn't expect that after practicing foreign kung fu to the extreme, it can be so powerful!" Although Zheng Weiguo is already a cultivator, his outer martial arts have nothing to do with Jia energy and internal breath, and it is also very helpful to him.

Only Zheng Xiaole snorted very unhappily, she used to be the sweetheart in the eyes of everyone, both the teacher and the senior brother cared about her, but now this attention has completely shifted to this new kid, how not to make her annoyed and jealous?

Zheng He's face was slightly gloomy, and he said: "There is an opportunity after the exchange, the outer kung fu is not like the inner kung fu, this kind of realm of improvement and understanding, can only be understood but not spoken, even if Yi'er tells all his experience, it may not be useful to you, if you can't even rely on the master realm to reach the realm of your own, it is a matter of talent, if you want to rely on the guidance of others to advance to the realm of the grandmaster, it is ......impossible for a lifetime! Yi'er, come with me to the practice room. ”

"Yes, teacher. ”

Fang Yi responded respectfully and followed Zheng He away.

Zheng Weiguo and Zheng Shuang glanced at each other, both nodded, felt that the teacher was reasonable, and immediately looked at Zheng Xiaole.

"Senior sister, do you want to go and practice Wing Chun together?" Zheng Weiguo said.

"Just go, I'm afraid you won't succeed?" Zheng Xiaole snorted lightly, raised his head proudly, and walked out first, muttering unhappily: "Damn teacher, I don't know what kind of martial arts I want to pass on that guy." ”

Zheng Weiguo and Zheng Shuang looked at each other and smiled, shook their heads and followed.

The three of them also thought that Zheng He was going to pass on Fang Yi's kung fu, but where did they think that the teacher was going to risk his life and take the following Nanshu fruit?

Inside the practice room.

Zheng He and Fang Yi sat cross-legged, facing each other, and between them was a box carved from Wen Nan wood, and inside were the two Wen Nan tree fruits.

"Yi'er, you take this memory chip, there are some explanations from me in it, in case I fail this time, or even if something happens, you will announce this memory chip to a few of your senior brothers and sisters. ”

Zheng He handed over a memory chip to Fang Yi's hand.

"Teacher ......"

The thin memory chip lay in the palm of Fang Yi's hand, but it seemed to have a thousand weights.

At this time, Fang Yi really regretted it, and was about to say something, but was stopped by Zheng He.

"Needless to say, I've made up my mind. ”

When Fang Yi saw Zheng He's resolute expression, he knew that it was useless to say anything.

Zheng He took out a dagger, which was almost exactly the same as the dagger he gave to Fang Yi at the beginning, and said: "Since this fruit is even valued by a fifth-level fierce beast, it must be very precious, I will now cut it into four parts, one by one, so that the danger can be reduced, and secondly, it will also avoid unnecessary waste." ”

"It's still the teacher who thinks about it. Fang Yi breathed a sigh of relief slightly, according to the teacher, the dangerous surname was indeed much lowered.

Zheng He took the dagger and pointed it at the center of the Wen Nan tree fruit, and then vertically, and the four petals that were cut were poured out in all directions.

There is no fragrance, as if its fragrance has already been dissipated in a short time when the fruit has just rived. And Fang Yi looked at it, only to see that after the bright red fruit was cut, the flesh was like a pudding, a jelly-like object, the bright red color was very pleasant, it was cut horizontally and vertically twice, but there was no juice flowing out.

Fang Yi and Zheng He glanced up at each other, and they could both see the surprise in each other's eyes, obviously neither of them had ever seen such a strange fruit.

Taking a deep breath, Zheng He picked up one of the petals, stared at it for a few seconds, and then put it in his mouth without hesitation.

Fang Yi's expression became nervous all of a sudden, and he watched Zheng He's facial changes closely, sensing Zheng He's qi, blood, and breath.

After chewing a few times, Zheng He's face suddenly became a little weird, and then his eyes suddenly showed joy, and he closed his eyes and concentrated on it.

Fang Yi immediately felt that Zheng He's qi and blood flowed faster, and at the same time, he felt that in his body, there was a new stream of qi and blood that was constantly spreading explosively from his chest, as if a slowly flowing river suddenly merged into another river, and as soon as the two rivers merged, the speed of the river's flow naturally accelerated!

"Sure enough, this Wen Nan Tree Fruit may be the Dragon Ball Fruit, which has a similar effect to the marrow element to enhance qi and blood!" Fang Yi immediately became overjoyed when he saw this, and at the same time, his heart was slightly relieved.

Fang Yi clearly felt that Zheng He was like a balloon that was constantly inflated, the qi and blood in his body grew rapidly, and the new qi and blood exploded so violently that even Zheng He couldn't retract it all at once, making the qi and blood involuntarily radiate outward through the pores of his body, and in Fang Yi's perception, Zheng He seemed to have a fire all over his body.

This situation is very similar to the dragon badger that Fang Yi encountered in the Canglong Mountain Range, the dragon badger is estimated to have just taken the fruit of the Nanshu tree, and he didn't care about storing his qi and blood, so he chased Fang Yi all the way, and the dragon badger at that time also looked like he was full of blood.

Five minutes later, Fang Yi felt that the fire that wrapped Zheng He was slowly getting smaller, and finally disappeared completely, and he knew that with the continuous enhancement of Zheng He's qi and blood, his ability to converge and swell his qi and blood was also constantly strengthening, and he was finally able to completely control his qi and blood without wasting it.

After another five minutes, Fang Yi sensed that the amount of new qi and blood in Zheng He's chest was gradually decreasing, and he thought that it should be that a quarter of the fruit was almost digested.

Seeing that Zheng He was always meditating and motionless, Fang Yi thought about it, picked up a petal of fruit, and sent it to Zheng He's mouth when the new qi and blood were getting weaker and weaker.

Zheng He seemed to realize something, opened his mouth, and ate the fruit in one bite.

Soon, Fang Yi sensed that the newborn qi and blood in Zheng He's body had skyrocketed again.

This time, except for a small amount of qi and blood leaking out of his body in the first half minute, Zheng He completely collected this qi and blood for his own use, and there was no longer any waste.

Ten minutes later, the second fruit was also close to being completely digested, and the rate of new blood production gradually slowed down.

Fang Yi compared, and now Zheng He's qi and blood have eighty percent of him. Fang Yi remembered that he sensed that Zheng He's qi and blood were only about half of his yesterday, and now it was only half of the Wen Nan tree fruit, which actually made Zheng He's qi and blood increase by thirty percent.

The energy contained in this fruit is greater than Fang Yi imagined!

"If a person who doesn't know martial arts eats a Wen Nan tree fruit, and can completely digest and store it, his qi and blood will be so strong that only a strong person in the Qi Shock Realm can be at once, it's really terrifying! Even if it's the marrow element, it is far from being comparable to this fruit! This Wen Nan tree fruit is really a rare spiritual creature between heaven and earth, and the marrow element, a thing made by people, is far from being comparable to it! However, this fruit is not something that everyone can eat, I am afraid that only ancient martial artists in the Qi Shock Realm can enjoy it, and Jia Xiu's words even have to peak the Qi Shock Realm, otherwise the body will not be able to withstand the soaring qi and blood at all, and it will be blown up by the huge qi and blood of the newborn!

Fang Yi remembered that at the beginning, Zheng He couldn't control his qi and blood, and a lot of qi and blood overflowed from his pores, completely like fire. With Zheng He's cultivation at the peak of the Qi Shock realm, and proficient in foreign boxing techniques, his qi and blood are already stronger than those of martial artists of the same level, but if he is replaced by other martial artists, he is afraid that it will be more exaggerated, and it is estimated that it is really going to be bloody, and the sun can't block it.

Thinking of this, Fang Yi was somewhat glad: "Fortunately, the teacher tried it first, otherwise, if I let the senior brothers and sisters take it first, it would be too dangerous, and when the time comes, unless I use the "Yuan Sucking Great Demon Wheel" on them to suck out their essence and qi and blood, I can prevent them from being exploded." ”

Chew Chew Chew Chew ...... Zheng He's body suddenly began to tremble slightly, and from the deepest part of his body, there was a sound of steel bars being entwined.

This sound came out and shook away, Fang Yi directly felt that the bones in his whole body were numb, and what surprised him even more was that many heaven and earth spiritual qi that were originally hidden in the middle of nowhere came out one after another, and a trace of it gathered to all the joints of the whole body, as if there was a suction force in the bone cracks, quickly absorbing them into it, such a speed was even faster than practicing with a stone bag before!

After being amazed, Fang Yi suddenly understood, it turned out that the force and frequency of the blow he had pondered the night before were not really the best, and now the continuous microwave tremor emitted from Zheng He's body was more effective than what he had pondered, and it could promote the absorption of heaven and earth aura!

Fang Yi's eyes suddenly closed, carefully experiencing and remembering this tremor from the outside in.

The sound that emanated from Zheng He's whole body became louder and louder, and the frequency of tremors became higher and higher, and slowly even Fang Yi couldn't bear it anymore, and he felt that the bones in his whole body began to ache.

As soon as his eyes opened, Fang Yi retreated back five meters, which was much better.

In an instant, Fang Yi felt an unknown change in Zheng He's body, and the next moment, Fang Yi found that he could no longer perceive Zheng He's qi and blood, or even his existence, as if the person in his eyes was just an illusory shadow.

Immediately after, Zheng He's body began to emit brilliance, and the brilliance of different colors surrounded Zheng He's body, making him look as if he was surrounded by a rainbow.

Zheng He's face at this moment was slightly different from before, looking more serene, quiet, and distant, and his skin was as smooth as jade. Obviously sitting there, it seems to have become a mountain thousands of feet away, hidden in the mist, which makes it impossible to see completely, as if it will disappear at any time.

Zheng He's current appearance is simply like a Buddhist monk who has attained the Tao and become a Buddha.

Suddenly, every bone in Zheng He's body made a sound like a bamboo explosion, and the new behemoth blood qi boiled out from the bones of his body. Fang Yi felt that Zheng He's qi and blood were erupting in a way that was ten times more violent than the previous Nanshu fruit, but there was no trace of qi and blood leaking!

The qi and blood continued to grow and grow, and soon surpassed Fang Yi, and a minute later, Zheng He's qi and blood had more than doubled Fang Yi before he stopped.

"Suck ......"

Fang Yi clearly heard Zheng He take his first breath.

In an instant, Fang Yi felt that something seemed to be sucked into Zheng He's body in the space around him, and the brilliance of Zheng He's body quickly converged.

"Hoo ......"

Zheng He exhaled in a long breath, it was as black as ink, and when this dark breath touched the air, it quickly dissipated into the air at an incredible speed, and it was never seen again.

"Drink—"

At this moment, Zheng He, who had been sitting upright with his eyes closed, suddenly opened his eyes, and two essence-like rays of light leaked out of his eyes, which actually made Fang Yi feel like two towering mountain peaks were stabbing at him, as if his body was about to be pierced by this gaze!

At a glance, it contains such a profound martial arts artistic conception, as if it is a fist intent attack!

This sharp essence light only flashed away, Zheng He's eyes were even deeper and darker than before, and Fang Yi saw that there seemed to be an irregularly shaped light flowing inside.

With his hands spread out to the side and his palms pressed down slightly, Zheng He seemed to be supported by others, his upper body straightened up, and after standing, his heels left the ground, only touching the ground with his toes, and his body shook slightly from side to side, as if he was standing in the water.

With his arms pressed down, Zheng He's toes suddenly left the ground, and the whole person flew up like feathers, floating half a meter above the ground.

Fang Yi looked at Zheng He in a daze, at this time, he was finally able to clearly perceive the kind of "heaven and earth energy" that communicated between the inside and outside of Zheng He's body, and it turned out to be the aura of heaven and earth!

The aura of heaven and earth is not only scattered under the earth, among all living beings, even the air is also full of heaven and earth aura, but the aura of heaven and earth in the air is too much different from the earth, so thin that even Fang Yi can't perceive their existence at ordinary times.

It was only at this time that Zheng He gathered many silks of heaven and earth aura scattered in the air, and then held himself up, allowing him to float away from the earth's gravity, that Fang Yi finally sensed their existence.

Fang Yi even felt that the trace of heaven and earth aura was passing through the acupoints of Zheng He's whole body, as if many people were opening their mouths and noses to breathe in the aura of heaven and earth.

Suddenly, like lightning flashed in Fang Yi's mind, Fang Yi finally understood that the so-called internal breath is actually the transformation and convergence of the heaven and earth aura in the air through the internal strength and mental method, and turn it into energy that can be used by human beings themselves! Heaven and earth aura is the origin of all the energy between heaven and earth!
