Zhou Yi got out of bed and walked out of the room and came to the courtyard to stretch his muscles.

Yun Yishang and the others have already fallen asleep, only the direction of the academy is still faintly transmitted, presumably because some students are still reviewing at night in today's lecture.

Zhou Yi stood quietly in the courtyard, and reconfirmed the operation method of "Dragon Elephant Prajna Gong" in his heart.

The first layer is skin refining, Zhou Yi's skin membrane has been baptized by dragon blood, and then he has taken the initiative to refine it with the true qi of the Northern Darkness. Now his skin is tougher than the skin that ordinary martial artists have refined in order. However, the practice method of this exercise is very different, and the refining method is even more interesting, because it is the cell membrane that is refined. When I think about it, some of the classics of Buddhism suddenly dawn on me.

The volume of the "Sanskrit Net Sutra" says: Lushena Buddha sits in the thousand-leaf lotus, incarnates a thousand Buddhas, and lives in the world of thousands of leaves, in which the Buddhas of each leaf world transform into tens of billions of Buddhas, sitting on the Bodhi tree.

This tantric martial art regards the human body as a leaf, and there are tens of billions of worlds in a leaf, and if you want to cultivate, you should start from the tens of billions of worlds.

The refining of the membrane is very simple, Zhou Yi retracts his mind and visualizes the membrane. After a long period of motionless visualization, the epithelia in front of me gradually enlarged, and gradually the cells on the epithelia can be clearly seen. Then follow the cultivation method on the cheats and start exercising the cell membrane.

It's no wonder that people with average qualifications can learn it within a year or two, cell membrane cultivation is difficult to remember, but real cultivation is extremely simple.

As long as the first cell membrane is visualized and cultivated, it can spread from one to the other and spread to the surroundings.

Zhou Yi's cultivation of the ninth layer of the day after tomorrow, with the support of a huge amount of true qi, only half an hour to refine the entire body membrane.

A thin layer of black sweat stains appeared on his body, and Zhou Yi did not stop, and continued to advance to the next layer.

The second layer of muscles, the same reason, except that there are obviously more muscle cells than the epithelium, but it takes a little longer, and it is only an hour to practice.

There was a little more black sweat on his body this time.

In the third layer of tendon refining, the cells on the tendons are relatively tight, and it is not very easy to visualize. After Zhou Yi was baptized by the Holy Dao, his spirit was far stronger than that of ordinary martial artists, and it took a lot of effort to visualize it, and only half an hour had passed.

The fourth layer of bone refining refers to the bones except the skull.

Bone cells are encased in bone, and although there are other such as osteotropia on the outer edge of the bone, bone cells must be refined to refine bones.

It is difficult to visualize bone cells, so Zhou Yi condensed his spirit into a needle, penetrated the bone before visualizing a grain of cells, and concocted it in the same way, refining the bone cells in the bone one by one. There are not many bone cells, and after finding the trick, it only takes half an hour to refine it.

At this time, Zhou Yi was already wrapped in a layer of pitch-black dirt, if it weren't for the brocade robe he was wearing, it would be difficult to find someone standing there in the night.

In the fifth layer of blood refining, the cells in the blood are always flowing, and it is difficult to reach one or one hundred like the first four layers. Zhou Yi thought about it for a while, and suddenly visualized the place of the heart with his spirit, all the blood must pass through here, and he waited here for the rabbit.

In the heart, the mind spreads, and the true qi also spreads, capturing a batch of blood cells and refining a batch.

An hour later, there was no more fish in the blood passing through the atrium, and Zhou Yi breathed a sigh of relief, feeling slightly tired.

The sixth layer of refining organs, just visualizing the atrium, but it is easy to refine the five internal organs, this layer is difficult to refine, and the pain is very unbearable when refining. The consciousness of ordinary martial artists exists in the body, and this kind of pain can make people hurt in their consciousness, and their consciousness cannot be concentrated, let alone refining.

Zhou Yi often sinks consciousness into his mind and cuts off the connection with his body, so after a burst of pain, he concentrates his consciousness and cuts off the connection with his body and stores it in his mind, leaving only a stream of cells for visualization.

In this way, the sixth floor is extremely simple, and it only takes a quarter of an hour to complete. And the consciousness that sank into the mind is still, and the mental exhaustion is relieved. After Zhou Yi took back his consciousness, he only felt that he was full of energy, so he marched towards the next level with a tiger's momentum.

He didn't realize how terrifying his current martial arts entry was, and ordinary people needed to spend decades cultivating the process, because all his special features were completed in just a few hours.

The seventh layer of marrow refining, the refining of bone marrow is like a comprehensive version of bone refining and refining organs, the spirit needs to be concentrated, but once concentrated, that kind of pain can make people crazy. Even Zhou Yi couldn't take advantage of it, Zhou Yi endured the pain, but when he gritted his teeth and refined, he found that each of his myeloid cells was refining extremely fast. If you think about it, it may have something to do with your own dragon blood soaking in the marrow.

As the name suggests, the dragon elephant has the power of the dragon elephant after practice. Although the dragon blood soaked by Zhou Yi is not as good as the real divine dragon blood, the purity of his dragon bloodline is also extremely high.

The bone marrow on Zhou Yi's body has actually been soaked in dragon blood, and it is infinitely close to the dragon clan, and it is naturally very easy to cultivate, that is, it will be completed in a quarter of an hour or two.

In the eighth layer of refining the skull, the tightness of the skull was stronger than that of other bones, and Zhou Yi almost condensed the spirit of the whole body, so that he could pierce the surface layer of the bone and visualize the bone cells. The cells began to be refined, but it took a lot of mental strength.

By the time the skull refining was completed, Zhou Yi had a feeling of mental prostration.

As for the ninth layer of brain refining, well, Zhou Yi really couldn't hold on. At this time, it was very bright, and the night passed. In one night, he has completed decades of hard work by other martial artists, and this kind of achievement is said to be unbelievable, I am afraid that the creators of "Dragon Elephant Prajna Gong" dare not believe it.

"Bhah!!It's so stinky!" Zhou Yi opened his eyes, and suddenly a foul smell came to his nose, which was the last scum of those parts of his body that had been refined.

"Bang! knock!" Zhou Yi raised his foot and prepared to go to the well in the yard to wash, but as soon as he stepped down, a pit appeared on the neat bluestone ground. Zhou Yi didn't react for a while, and suddenly threw himself forward and fell to the ground, and there was another sound of stone shattering.

Yun Yishang walked into the courtyard and prepared to serve Zhou Yi to get up and wash, but this is what he saw.

"Ah, who are you?" Yun Yishang exclaimed, the person in front of him was covered in pitch-black dirt and emitted a foul smell, but his clothes and figure were somewhat similar to Brother Zhou.

Zhou Yi hurriedly turned over from the ground, with a wry smile on his face, and said in his mouth: "Yishang, it's me!"

It was only at this time that he realized that he had unknowingly broken through to the eighth layer, and he had been paying attention to the next layer of refining just now, but he didn't notice that his strength was now extremely great, was this a hanging?!

"Brother Zhou, what's the matter with you?" Yun Yishang hurriedly trotted over to help Zhou Yi and asked anxiously, not caring about the stench and dirt on Zhou Yi's body at all, but it moved Zhou Yi's heart.

"Hehe, last night's cultivation of a body refining kung fu, these are all dirt in the body! The strength has increased too much, and I can't control it just now, but it made you see a joke!" Zhou Yi gently broke free of his arm, not wanting to stain Yun Yisheng, and explained in his mouth.

"Hee-hee-hee......" Hearing this, Yun Yishang couldn't help covering his mouth and chuckling while being relieved, but he didn't expect Brother Zhou to have such a funny thing.

"I'll go wash it first!" Zhou Yi heard her chuckle, and couldn't help scratching his head in embarrassment, but when he grabbed the next sludge, he suddenly became even more embarrassed, and his body moved in the direction of the water room, and slipped away.

A big hole appeared on the courtyard wall of "Bang ......", Zhou Yi spat out the ash foam in his mouth, and the black stains on his face were stained with white stone powder, which added a bit of fun.

"Hehe, the strength is not controlled, the strength is not controlled!" Zhou Yi explained awkwardly to Yun Yishang in the courtyard.

"Hahahaha......" This time, in addition to being surprised by Zhou Yi's strength, he was able to knock a big hole into the wall with an unintentional collision. Yun Yishang really couldn't help it, and she trembled with laughter. Zhou Yi fled in the midst of laughter, but in his heart he was depressed that he had suddenly gained strong strength and could not command him like an arm.

"Sister Yishang, what's the matter? What makes you happy like this?" Yue Banxuan heard Yun Yishang's laughter and walked over.

Looking at Yun Yisheng, who was laughing breathlessly and standing with his waist up, and a big hole in the wall that vaguely saw the shape of a human, Xiao Nizi was full of doubts.

"Hehe, Sister Banxuan, it's nothing, Brother Zhou......" Zhou Yi definitely didn't expect that the quiet and gentle Yun Yishang also had such a gossip side, and she muttered to tell Sù Yue Banxuan what happened just now.

"Haha......" Yue Banxuan was even more unbearable, hearing that Zhou Yi was so embarrassed, wahaha laughed wildly, and the sound made Zhou Yi, who was taking a bath next to the well in the water room, almost fall to the ground.

Next, in the courtyard of the City Lord's Mansion Zhou Yi in the morning, there was no stopping the laughter of the second daughter's silver bell.

During the meal, Zhou Yiyi made the chair fall apart;

Carefully picked up the chopsticks and porcelain bowl, but one did not pay attention, the chopsticks broke into four, and the bowl was also pinched into pieces.

After a while, Zhou Yi rushed out of the restaurant, leaving the second daughter with a stagnant smile.

"In today's class, you can help me arrange it, and let them copy "Shi Shuo" a hundred times!" Zhou Yi's figure walked away, leaving behind a sentence of gnashing teeth. I was embarrassed, and I couldn't blame the second daughter, so I had to vent it to a group of innocent students.

Anyway, he will definitely not go to the lecture hall to make trouble, he wants to go to the barracks, practice well, and must master the strength of this body. Otherwise, this day will not be lived!

The two girls sat at the table, looked at each other, and couldn't hide a hint of playful laughter. It is rare to see the always calm Brother Zhou's gaffe, and so many troubles in a series make them feel that he is much closer.

Running all the way, the speed is fast, and at the same time, adjusting the strength in the familiar body. The half-elves on the street only felt a gust of wind blowing, and a figure flashed in front of them.

The strength has increased a lot, and naturally the speed has also increased greatly. One step down, the huge explosive force made his body rush forward.

Not long after, Zhou Yi rushed out of the city, and the military camp in the distance was already in front of him.
