Lu Kun didn't know that a phantom of a gibbon had appeared outside his body, and this phantom could not be detected with his divine sense, he only cared about understanding the changes that had occurred in his physical body during the year.

After a year, although the two hundred and six bone magic weapons were successfully refined, the danger in the middle, Lu Kun still has lingering palpitations.

The refining of the bones of the limbs is easy to say, because on the limbs, in addition to the bones, they are muscles, and the muscles can be reborn after they are burned, at most they can bear some pain.

However, the torso and skull are very dangerous.

The torso contains the heart and other most important organs for the physical body, if it is destroyed, the physical body is afraid that it will die directly, Lu Kun does not think that these internal organs can be reborn like muscles.

Therefore, when refining the ribs, sternum, spine and other trunk bones, he maximized the power of the Thunder Shield to protect the organs inside and resist the calcination of the mana true fire.

At the same time, in addition to enduring the pain of melting bones, he also had to merge with Qin Yushu's divine consciousness and depict the magic circle, and he also had to rely on the abundant spiritual energy of Demon Spirit Island, coupled with the great increase in the mana in Lu Kun's limbs and bones, so he could barely support it.

Behind the torso, is the hip bone, that is, the refining of the pelvis.

This is the most terrifying thing for Lu Kun, the organ that symbolizes a man, which was controlled by him with muscles, shrunk into the pelvis, and then protected it with a thunder shield.

The refining of this hip bone, if Lu Kun's thunder shield can't support it, I'm afraid that such a precious organ will turn into ashes.

Fortunately, the hip bone was refined after the trunk bone, and with the greatly increased mana of the torso bone, the thunder shield was supported to the end, but Lu Kun was not in good shape in the process of portraying the magic circle, and almost made a mistake.

In addition to the torso and hip bones, the rest is the skull.

Lu Kun attaches great importance to the skull, as long as the bone treasure of the skull is refined, with the strong magic circle of the magic weapon, it will be the strongest defense of his brain.

No matter what kind of immortal cultivator, Zhihai and Divine Soul are all living in the brain, so in the battle between immortal cultivators, if they want to kill each other, the first target of attack is the head.

After Lu Kun entered the Bone Treasure Stage, the skull with amazing defensive power had already saved his life, and now if he was tempered into a magic weapon, I am afraid that the monks of the Dan Stage would not be able to kill him.

The skull is relatively powerful, but the brain inside is too fragile, Lu Kun put it at the end to refine it out of caution, and the twenty-three skulls are refined separately, and the thunder shield can focus on protecting one of the areas.

The further back it went, the easier it became, but despite this, it took almost two months for the skull to be completed.

After the whole body skeleton was formed, the mana in Lu Kun's bones seemed to come to life, and the magic weapon of a single bone was a pool of stagnant water, and after it was formed, it became a river of a virtuous cycle.

The thunder attribute mana spontaneously circulated in all the bone magic weapons, and the aura between heaven and earth also seemed to be attracted by more than two hundred bone treasures and gathered.

So Lu Kun used this surging energy to quickly recover the muscles outside his body, and at the same time sensed the changes in his bones.

Now the two hundred and six bones have become the simplest, only the magic weapon of the strong magic circle.

These hundred or so bones are equivalent to the kind of mosaic magic weapon of Yueyang Sect, and unlike the complete set of magic weapons, the inlaid magic weapon can be activated by many pieces at the same time.

Like Qin Yushu's five-feather Qiankun knife, the position of the head of the five flying knives has inlay points, and when the five flying knives are combined together, it becomes a magic fan.

This magic fan is no different from urging a magic weapon, but the power is more powerful than a single magic weapon, and of course, the mana consumed has also increased.

In other words, Lu Kun's more than 200 bone treasures, he can completely urge them together, for example, when he makes his right fist, it is equivalent to twenty-seven bone magic weapons in his palm, and the lower arm and the big arm bone magic weapon attack together.

It seems that the power is terrifying to the extreme.

But......

Lu Kun's whole body bone magic weapon only depicts a solid magic circle, and when he uses mana to urge, he only exerts the hardness of the magic weapon to the extreme, without any magic power in terms of attack power.

But what Lu Kun wants is the hardness of his bones.

The real strength of physical cultivation should rely on the power of the physical body, breaking ten thousand laws with one force, allowing you to use all kinds of weird and powerful spells, or all kinds of strange magic weapon attacks, and physical cultivation can be broken with one force!

After Lu Kun entered the bone treasure period, even if he didn't urge the magic power of the arm, his strength would reach 200,000 catties, but he still had to rely on the psychic magic weapon to fight.

If you want to exert great strength, you must withstand the corresponding force of the shock, and only by relying on a weapon at the magic weapon level can you hit the corresponding power attack without harming your own body.

Now that Lu Kun's whole body bones have become magic weapons, the strength of the material has increased greatly, and when he urges the mana, these magic weapons will become even harder.

In this way, he can completely use his fists, feet, bones and joints to fight against the magic weapon of the immortal cultivator, and unleash a terrifying force attack, and he will not be afraid of the damage caused by the huge power counterattack.

The middle stage of the bone treasure is the initial stage of physical cultivation to bring the physical body to the extreme!

Lu Kun's heart was full of thoughts, and he immediately thought of the various fighting methods derived from the bones after they became treasures, and his heart was surging for a while.

With the absorption of the aura, the muscles and skin outside Lu Kun's body gradually took shape, and the aura of heaven and earth also slowed down, and the phantom of the golden giant ape outside his body gradually disappeared.

At the same time, the mana in Lu Kun's bones tended to be stable, exuding a surging thunder attribute aura, and in his perception, it had completely reached the mana level of the middle stage of the Jiedan.

You must know that before refining the bone treasure, the mana in Lu Kun's body did not reach the peak of the early stage of the knot, and it was still at the level of the early stage of the knot, but in the confrontation with the blood magic power, it became more refined.

Now that the two hundred and six bone treasures have been refined, they have immediately risen from the mana in the early stage of the knot to the middle stage of the knot, which shows the huge transformation brought about by the refining of the bone magic weapon.

For an ordinary early stage cultivator, it would take a lot of time just to cultivate mana to the peak of the early stage.

After another day and night, Lu Kun's body had fully recovered, and the organ under his crotch that had been retracted into his pelvis was also released by him.

His skin was white and red, and a faint layer of treasure light came out of his skin.

"Hey, the new muscles and skin have increased in strength. After his body recovered, Lu Kun slowly fell to the ground, clenched his fists, and said a little strangely.

After thinking for a while, he directly raised his right fist and slammed it to the ground.

There was no thunder shroud on his fist, and Lu Kun just used the bone mana in the fist, making the fist bones extremely hard.

"Boom!"

A huge explosion sounded, and the ground, along with the prohibition above, was directly blown apart by this punch, and even a crack appeared on the ground, and there was a tremor in the cave, the internal prohibition was damaged, and a lot of rubble was scattered.

Lu Kun stared blankly at the fist whose skin was not broken, and muttered: "In the middle of the bone treasure, the strength of the bone treasure has actually increased to a huge of 300,000 catties, which is almost equivalent to the strength of the previous arm, and the defense of the muscles and skin has also increased a lot. ”

"By the way, muscles are reborn from the surface of bones, and the bones have undergone essential changes, from materials to magic weapons, then the derived fascia nodes have also undergone transformation, thus growing stronger muscular skin. ”

Lu Kun recalled the previous scene of white bones and muscles, and somewhat understood the reason:

"The muscles that exert normal force, also known as skeletal muscles, are all dependent on the bones, and when they reach the realm of the bone treasure stage, they will gradually strengthen as the bones become stronger. ”

Lu Kun's expression suddenly changed: "In this way, the middle stage of the bone treasure is the same as the original blood coagulation stage, it is the most important link in the current realm, and the bone treasure stage can only be regarded as truly powerful when it enters the middle stage of the bone treasure and refines two hundred and six bone magic weapons." ”

Then Lu Kun looked at his body, slowly floated up, and said with a different color flashing in his eyes: "The Dan Stage Cultivator flies, relying on his own strong mana, if you want to accelerate, you have to connect with the treasure light of the magic weapon." ”

"And my whole body has become a magic weapon, and the speed of flight will soar. ”
