The biggest difference between the body of the bronze armored corpse and the body of a human is that the former has been tempered by countless years of cold breath, and it can basically be said to be similar to a demon beast, and some parts can be used as refining materials.

For example, the black muscles on the bronze armored corpse have tenacity and strength, and they can even hard-connect the attack of the magic weapon, which shows that it is powerful.

What Lu Kun has to do now is to use the power of annihilation generated by the collision of thunder attribute mana and cold power to quench the bones of the bronze armored corpse.

This process is equivalent to the cultivator of the Dan period using mana true fire to calcinate the materials of the smelter, but the mana true fire is replaced by the power of annihilation.

At this moment, Lu Kun urged the thunder attribute mana in his body, followed the right palm of the corpse man, and entered the bone of his right arm, this kind of destructive power is extremely strong, and the mana that has a restraining effect on the power of yin and cold immediately aroused the resistance of the power of yin and cold.

A large amount of cold power erupted from the corpse pill in the corpse path human body, and spontaneously rushed towards the right arm that was invaded by the thunder attribute.

"Corpse Dao man, restrain the power of yin and cold, and control Yicheng into his right arm. Lu Kun had expected this reaction and immediately gave instructions.

The corpse Dao man sitting in the insect chrysalis hurriedly restrained the energy in his body, and according to Lu Kun's words, sent it into his right arm.

The power of yin and cold in the bronze armor corpse still runs through the meridians in the body, and it will not be stored in the bones, nor will it enter its own bones.

And Lu Kun's refining body has become an instinct to control the mana to run in the bones, and the bones of the bronze armored corpse are still not much different from humans.

Therefore, his mana was directly injected into the bone of the corpse man's right arm, and the cold power in the meridians of the corpse man's arm involuntarily rushed into the bone after feeling the extremely threatening foreign body of the thunder attribute mana.

The thunder attribute can be said to be the nemesis of the power of the cold, otherwise Wang Shitong would not have been destroyed by the two lightning techniques, and the power of the cold must have enough to restrain the thunder and lightning, and the bronze armor corpse is the home of the power of the cold.

"Woohoo!"

A muffled sound appeared, and the thunder attribute mana injected by Lu Kun was annihilated by the surging cold power, producing an extremely destructive energy.

This energy directly appeared in the bones of the corpse man's right arm and exploded, shaking the bones of the bronze armored corpse's right arm to creak.

After the explosion, this energy disappears.

Lu Kun's eyes flashed with golden light, observing the bones of the bronze armored corpse, and a trace of thunder attribute mana was urged in his hand, which re-attracted a part of the cold power and entered its bones.

This trace of mana is too scarce, and the power of yin and cold directly dissolves it, and there is no power of annihilation, but after these cold power enters the bones, it spontaneously spreads outward.

The damage caused by the previous annihilation of the bones was recovered under the effect of these cold powers.

Lu Kun showed a look of satisfaction, one destruction, one repair, is the basic process of refining the bones of the bronze armored corpse, and then it only needs to be repeated continuously, and the injected mana can be gradually strengthened.

Seeing Lu Kun's expression, the corpse Dao man was a little confused, and his eyes glowing red looked at his right arm blankly, obviously not knowing that he had just completed a round of tempering.

Lu Kun immediately sensed what the corpse Dao people thought, and he sighed very emotionally in his heart: "The nerves of this bronze armored corpse are not sensitive at all, plus it has been a corpse refining for too long, and most of the pain in the physical body has basically disappeared, and it can't feel the pain of this bone refining at all." ”

Giving the corpse Dao man continued to give instructions to control the power of Yin and Cold, Lu Kun continued to repeat the previous tempering.

This increased the bone strength of the bronze armored corpse, and it was also a reference for his future cultivation path.

The corpse Dao body is a middle-level bronze armored corpse, although the bone strength is a little worse than Lu Kun, but it is also stronger than him who was the original quenching body, and the reference value for his bone treasure stage cultivation is incomparable.

The bones in Lu Kun's body, after being crystallized with mana, can be regarded as a refining material, and according to the normal development of the bone treasure period, it is to use the crystallized mana in the bones to slowly cultivate.

It's like a monk in the Yudan period using mana to nourish the natal magic weapon.

But that's a long time.

Lu Kun has been in the bone treasure stage for more than a year, and according to his observations, it will take at least five hundred years to use the mana of the early stage of the knot to nurture the bones of the whole body into a magic weapon step by step.

With his longevity in the Dan period, it is impossible to complete it, so he must use other methods to accelerate the tempering of bones.

Lu Kun had also encountered such a dilemma in several previous realms, and the solution was to use higher-level energy to refine his body.

But Lu Kun's xenomorph thunder attribute mana at the early stage of the knot pill is already stronger than other attribute mana, and if he nourishes his bones, it is completely equivalent to the mana of other attributes in the middle stage of the knot.

The bone treasure period is tempered by bones, which are wrapped in muscles, and if you look for destructive energy from the outside world, you will inevitably damage the muscles of the whole body.

Even if Lu Kun can grow muscles from the bones now, he still needs a lot of mana to spawn, and if he uses it to restore muscles, the bones that have been tempered will not have enough mana to recover.

So what a surprise it was when Lu Kun discovered that the thunder attribute mana could produce the power of annihilation with the power of yin and cold.

This energy is directly generated in the bones, and when it appears, it can quench the bones without destroying the muscles and internal organs, and the crystallization mana in his bones can directly treat the bones.

In this way, the speed of cultivating the bone treasure has greatly increased, and according to Lu Kun's inference, as the bone treasure gradually takes shape, the crystallized mana it can contain will also increase.

The mana of his physical body will gradually increase to the middle stage of the knot, or even the late stage of the knot, as for what level of mana in the body will reach after the bone treasure is truly formed, Lu Kun can't infer it now.

Lu Kun kept refining the bones of the bronze armor corpse, and at the same time confirmed himself, and became more confident in this method to promote the cultivation of the bone treasure period.

As long as the corpse Daoist enters the level of a high-grade bronze armored corpse and the power of yin and cold in his body becomes more refined, he can help him cultivate in reverse.

Because the power of yin and cold is restrained by the power of thunder and lightning, it must be more refined, and if the mana in Lu Kun's body enters the middle stage of the knot in the future, it is unknown whether the high-level bronze armor corpse can still help with cultivation.

Lu Kun can now be said to be groping for a dark path, without anyone to guide him.

Although the cultivation of the Bone Treasure Period had a direction, Lu Kun always felt in his heart that this was not the right path, because such a cultivation method could not be handed over to his disciples.

For example, after Zhao Qingtian was promoted to the Bone Treasure Period, the power of wood attribute mana and the power of yin and cold could not produce the power of annihilation, even if he used the principle of the five elements to restrain each other, he would not be able to succeed.

Because the mana of the five elements will only repel each other after encountering, and it will not be like a mortal enemy, fighting to the death, and it is impossible to produce a higher level of annihilation energy.

Lu Kun shook his head, sighed, did not stop the movements in his hands, and continued to refine the bones for the corpse Dao man, now he can only take one step at a time, maybe when he enters a higher realm, there will be a new way.
