Beneath the skin, the 639 muscles are solid, and these muscles are not bulging or thick, but they are like a steel wire kink, and a slight contraction is an unstoppable force.

Washed away from the glitz, heavy as iron, dormant like a beast, once instigated, these 639 monsters will pull the heavens and the earth, and put savage minions on Yan San's machine.

"Bronze skin!"

Yan San couldn't hide his joy, and grinned silently. The first weight of refining the body, refining the skin and flesh, ordinary body cultivation requires a huge amount of financial and material resources, decoction and medicine, tonic elixir to eat, this is the most basic consumption, in addition, it is necessary to polish all year round, bear weight, fight, wrestle and even beat, in order to refine the medicinal power into the skin and flesh, enhance the strength and resistance to hits.

The culmination of this process is Yan San's current state: 'Copper Skin Shen Muscle', which means that the skin is as tough as metal, and the muscles are as heavy as iron. After refining the flesh and skin, the physical cultivation can be regarded as truly entering the world of monks with the strength of the flesh.

One blow to break the stone, hit people like flying, and then cooperate with martial arts, if the same first-order monk is close to the body, it is a tragedy with a capital letter. This stage Yan San had already passed, and he thought that his physical cultivation level had reached the 'third order', but in fact, it was just the primordial body that had been tempered by the Heavenly King's Technique and reached the third order.

If Yan San's previous 'Third Order of Physical Cultivation' was indiscriminately washed and struck by natural rain and thunder to form a piece of unpolished peerless iron, then the formal Lang Taosha cultivation was a superb blacksmith who began to shape this piece of iron, knocking out a little edge. It is conceivable that if the follow-up bones, tendons, blood marrow, and five internal organs are all tempered, it will be a peerless divine weapon.

Yan San felt the huge changes in his body, his body shook slightly, his skin tightened for a moment, his muscles contracted violently, and the sweat all over his body was violently shaken, like a small tree after a rainy day was shaken violently by a pair of big hands, and the stagnant water on the tree was shaken so that there was no drop left, only the brilliance of raindrops was left.

Then, Yan San found that he had been demoted!

Originally, he was the third order of physical cultivation, but after this time of physical cultivation, he directly retreated to the second order, and it was foreseeable that if he continued to go retrograde, he would decline, but Yan San was overjoyed.

The decline of the original physical body level is exchanged for the start of the genuine body cultivation level that is more suitable for fighting, just like using a piece of iron to start forging a knife, and the consumption of iron casts the edge of the knife, and this business is not a loss. On the other hand, Yan San still had a second-order primordial body cultivation left, and there was still a lot of iron, so this knife could continue to be forged.

In the past, Yan San's physical level was comparable to the general physical cultivation, and the potential of the body was tempered by the waves and sands for many years, but there was always a feeling that could not be used in the battle, like a lake full of water, but only a small opening was opened, and the water in it could only leak out a little at a time through this opening, and now, Yan San felt that this opening had been expanded into a small river, and it would continue to expand, and one day it could expand to the point where the lake would be poured out at one time, and the flood would be monstrous and unstoppable。

Yan San's spirits were invigorated, but his body did not allow him to continue cultivating. The meal has to be eaten in one bite, no one can eat a fat man in one bite, and the immediate need is to recover from the injury first, and then step by step transform the body savings into combat effectiveness.

Half a month later, Yan San's injuries recovered and he broke through.

The crow had been waiting for a long time, a little happy and a little envious, but his face was calm and light: "What kind of trick have you practiced? It's a bit interesting, you can actually reach the realm of 'copper skin and heavy flesh', it seems that this injury is not in vain, and you have broken through!"

Yan San said, "Thanks to your reminder, I have figured out a key point, this retreat has benefited me a lot, and in a month at most, I will become a full-fledged second-order body cultivator!"

The crow scratched his head and said, "Aren't you stupid? Aren't you just a third-order physical cultivator?"

Yan San laughed and said, "It's good to practice back...... You don't understand, it's called re-furnace reengineering, and it comes naturally!"

The green butterfly on the side flattered and said, "Third Master, you...... It seems that I have lost a lot of weight, can this kung fu still have the effect of losing weight? Can you teach me?"

The crow glanced at Yan San's red upper body, Yan San did lose some weight, his body was more slender, and his originally thick muscle groups shrank a lot, but the skin was tense, and the muscles below him occasionally contracted with Yan San's movements, revealing a hideous outline through the flesh, reminiscent of a dormant tiger, and there was a strong dangerous aura between the contraction and expansion of the skin and flesh, as if ready to strike a shocking blow at any time.

At that moment, the crow glanced at the green butterfly and said, "What do women and Taoists know? What is this called thinness? This is called fat is not obvious! Master, am I thin? I don't see you caring about me?" Then he looked Green Butterfly up and down, and wondered, "What kind of fat did you lose? Where did you gain weight?"

Green Butterfly pointed to her waist embarrassedly and said, "Senior Sister Red Bee said that I have a thick waist and big hips, and call me a fat woman!"

"She knows! I like you like this, don't listen to her...... Is it still called a woman?' The crow scolded obscenely, and a pair of colored hands climbed up the waist of the green butterfly, pinching it down, and the green butterfly looked at the crow's pleated face with watery eyes, and saw that the old pervert's saliva was about to flow down......

A pair of dead adulterers and adulteresses!

"Don't want to change the subject, what about the vulnerous ghost face you promised me?" I'm the most honest, and if someone else says they want to give it, then I must!' Yan San turned his neck and twisted his shoulders, his muscles like twisted dragons under his skin, and said slowly.

The crow suddenly froze on the green butterfly's buttocks, pushed the green butterfly away, and his face was as ugly as if he had been bitten by a dog, and said helplessly, "Come with me!"

Guo Ergou's "cave mansion" is not the kind of cave mansion that the gods call themselves, but really lives in a cave. After the crow took over, he disliked being too childish, and drove away the half-dead people in the two adjacent caves next door, and directly let the coolies get through...... Now it's more like a rat hole, and it's going in all directions!

Now the place where Yan San is located is the original cave of a crow's neighbor, and the cave has been hollowed out entirely, forming a huge space with a height of five meters and a length and width of more than fifty meters.

In the middle of the cave there is a stone pillar that leads to the top of the cave, and the five people can't hold it together, like a wall, but it is a huge natural black stone, which is dug up and does not move, and becomes the keel of this cave. On the stone pillar were two large iron chains as thick as an arm, looking at the dark color, I am afraid that it was mixed with a lot of gloomy iron, and it was difficult to cut off ordinary magic weapons.

The iron chains stretched to both ends of the cave, and the blood was mottled. On top of the chains, there are many smaller chains, more than three meters long. The chains trembled, the clanging sound was endless, and the roar of the beast was heard from time to time.

Thirty or so beasts were tied to the thin iron chains, all of them tigers and wolves, wild and untamable, and roaring at the stupid laborers who were digging holes.

"This is?" Yan San asked suspiciously.

"The vampluster face will suck a lot of blood, and if you don't find blood for them, you're going to suck my blood!" replied the crow, pointing to the two black wolves, which were as strong as calves, "There they are!"

Yan San saw that the two giant wolves were struggling wildly, scratching their bodies from time to time, and their sharp claws and teeth brought up blood marks, as if there was something terrifying in their bodies, and they immediately understood what was going on with the crow's so-called warmth, which actually used the body of the beast as a furnace for the ghost face to suck blood.

"Aren't your souls sealed in the Xuanyuan Secret Realm for six hundred and fifty years?, you have long lost your body, how can these ghost faces survive without sucking blood?" Yan San asked.

The crow said, "Those seven Blood Floating Slaughter have been cultivated by me, and if they are part of me, I will not die, they will not be destroyed. These two have not yet formed, so they have to let them go out to hunt some wild food by themselves, and most of the time they are dormant, but fortunately, they are nourished by the 'Nine Heavens Wind Source', and they will not starve to death. If not, where will it be your turn to pick up the bargain?'

Yan San nodded and said, "So, these two ghost things are going to drink blood every day?"

The crow said: "The vending ghost face feeds on blood, and it is naturally inseparable from blood to eventually evolve into the Blood Floating Massacre, and since the evolution into the Blood Floating Massacre, there is no need to suck blood, the master's essence blood, spirit element, and soul element can all be fed, of course, it is best to let it suck blood occasionally, otherwise it will gradually lose its ferocious aura and its power will be greatly reduced......

As he spoke, one of the ghost-faced blood wolves trembled violently, stopped scratching wildly, and its body shrank rapidly at a speed visible to the naked eye, and soon became skin and bones, falling to the ground like a bundle of broken grass. After a while, the abdomen cracked, and out of it rushed out a fist-sized blood-colored monkey, delicate and cute, but full of fangs, and a vicious face.

"These two ghost faces were painstakingly refined by me using the 'Vampire Ape' with soul arts, and they were originally killed by tens of thousands, but they were about to evolve into the Blood Floating Massacre, but they encountered Murong Kuo's old grandson...... It was also Lao Tzu who poured blood mold and was trapped for 650 years. In addition to the cooperation of the void souls bred by the soul seal, the most important thing is that in the past six hundred and fifty years, I have used the Blood Floating Slaughter to invade the Murong Kuoyuan Array!" the crow sighed.

"Oh, is there still such a usage for the Blood Floating Massacre?" Yan San asked.

The crow despised Yan San with an ignorant eye, and said, "Do you think that the Blood Floating Slaughter will only suck blood? The Blood Floating Slaughter is not a soul or a weapon, if it is alive or dead, it can cover the sky and the earth, and the blood can wash the sky, and the small can be condensed into fine dust and swallowed into the belly, it can be incorporated into the weapon to become a blood-sucking evil soldier, and it can be incorporated into the Yuan Array to become a bloodthirsty fierce array, which is ever-changing, the use is wonderful, and it is rumored that it can continue to be promoted, but it is not something I can speculate." 』

As he spoke, the crow's heart ached again, and he said, "These two ghost faces have followed me for many years, they are really closer than my son, and they are born with a higher level than ordinary ghost faces, and they have been cultivated in the 'Nine Heavens Wind Source' for hundreds of years, and their quality has long changed, I am really reluctant in my heart, young master, you see...... Why don't we change our requirements?
