In the depths of Demon Spirit Island, in a cave in the Eight Spirit Valley.

Zhao Qingtian wore a huge wooden bead necklace around his neck, and sat cross-legged in a spirit gathering array.

Different from the ordinary Spirit Gathering Circle, there were six small pools in each of its six corners, which contained a large amount of corrosive liquid, some purple, some red, and several of them were dark green, all of which seemed to be some kind of highly poisonous thing.

The venom emitted smoke of various colors, and the rich aura around it converged towards Zhao Qingtian's arms, legs, chest, and back, and there was a faint dark green mark in these six places.

In addition to this inexplicable imprint, Zhao Qingtian's skin outside his body sometimes turned dark green, sometimes red, and randomly changed in the colors of the six venoms, which was very weird.

And the muscles on Zhao Qingtian's face kept twitching, as if he was suffering a lot, and the way he tried to break through the Bone Treasure Stage at this time seemed to be very different from Lu Kun.

......

More than 20 years ago, after Zhao Qingtian first entered the Great Perfection of Quenching the Body, he devoted himself to cultivating the method of concentrating internal organs, and he relied on his Yuanmu Refining Body to have a strong recovery power on the physical body, and all kinds of poisons did not stop at all.

In the case of a large amount of poison quenching his body, Zhao Qingtian's internal organs were rebuilt much faster than Lu Kun expected, and it had been completed in twelve years, and the purity of his mana had increased by as much as two layers.

Completing the first internal organ recultivation in such a short period of time made Zhao Qingtian rise to the idea of rebuilding the second time, anyway, the poison in his hand was sufficient enough to support the second time, if the second time was completed, then his physical body mana would be almost as much as fifty percent pure, and the chance of condensing the pill and melting bones would increase greatly.

But his internal organs were condensed again, and after taking poison to cultivate, he found that the physical mana in his body contained toxins at some point.

Zhao Qingtian carefully investigated, there were two kinds of toxins contained in the mana of this flesh body, both of which were pure wood attribute poisons, and these poisons were very sticky in his mana, not touching his internal organs and flesh.

It was as if these poisons were afraid of his body with amazing recovery power, and instinctively hid in the flesh mana of the wood attribute, although the flesh mana contained toxins, Zhao Qingtian did not feel any discomfort, indicating that these poisons had completely fused with him.

Most of the poisons of the Holy Poison Gate have more or less some wood attribute properties, so after he quenches his body with poison again, many toxins will be directly absorbed by the mana of the flesh, and the damage caused to the flesh is pitiful, and there is no pure body effect.

With this kind of change, Zhao Qingtian was a little speechless at the same time, his mind also became active, he thought of the holy poison gong technique, because his phenomenon was somewhat similar to that of immortal cultivators who cultivated poison skills.

In the Holy Poison Skill, some slight toxins are refined through magic power, and gradually the magic power contains severe poison, and then gradually increases the amount of poison refining, which is how Du An cultivates the ten poisonous magic power.

And Zhao Qingtian is also refining poison, the difference is that he wants the poison to corrode the flesh body and achieve the effect of refining the flesh, who knows that these few spiritual poisons are afraid of his strong recovery body.

Compared with the physical body, the mana of the pure wood attribute has a high degree of compatibility with the poison, so the toxin actively integrates into his mana, so that Zhao Qingtian inexplicably cultivates the mana containing the toxin.

Although Zhao Qingtian's physical cultivation qualification was only four stars, his comprehension was extremely high, and his mana was fused with toxins, so he immediately thought about whether he could use Du An's Ten Poisons in One method to help break through the Bone Treasure Period.

Since Lu Kun got a lot of poison refining materials, Zhao Qingtian has basically mixed with Du An, one has amazing physical recovery and can test poison, and the other is proficient in poison refining, so Zhao Qingtian knows Du An's exercises very well.

Duan's ten poisonous magic power can be said to be subdivided into ten kinds of magic power, and each magic power contains a toxin.

The normal Holy Poison Gong Pill, first of all, must condense the magic power into a magic pill, and then find a way to smelt the ten kinds of toxins into one poison, so that it can form the Ten Poison Demon Pill, which is extremely difficult.

The cultivators of the Holy Poison Gong in the Holy Poison Sect often make mistakes in the integration of toxins after successfully forming a pill, causing the toxins to get out of control and their bodies to rot and die.

And in the poison refining inheritance obtained by Du An, there is a secret method to assist the Holy Poison Gong Pill.

It is a secret technique of alchemy, first fusing the toxins in the magic power together, and the toxins are combined into one, so the magic power corresponding to each toxin is more easily condensed together, and the difficulty of becoming a pill is greatly reduced.

It is precisely because of the loss of this poison refining inheritance that there are very few elders in the Holy Poison Sect who practice the Holy Poison Skill.

Therefore, when Zhao Qingtian's physical mana was integrated into the toxin, he thought of the secret technique of alchemy with ten poisons in one, which might not be able to help him increase the chance of condensing the pill and melting his bones.

The condensing pill and bone melting of physical cultivation is to condense the mana of the flesh into the bones, become crystal mana, and integrate with the bones to achieve the mana of the knot pill level, and prepare the bones for becoming treasures.

The difficulty of breaking through the bone treasure period, like that of ordinary immortal cultivators, is the step of condensing liquid mana into crystals, and the ten poisons are combined into a venom fusion method, which reduces the difficulty of mana crystallization.

Therefore, during the years when Lu Kun was in retreat, Zhao Qingtian studied in this direction, and kept discussing the art of alchemy with Du An, which really made him figure out a method.

That is to condense the poisonous wood mark, smelt the six poisons with mana, and finally the six poisons are combined to melt the bones.

Physical cultivation needs to condense the mana imprint on the bones, his master Lu Kun is the condensed thunder attribute imprint, and his sister Zhao Xue'er condenses the ice attribute imprint.

These marks are located on the limbs and on the front and back of the chest, six places.

Finding the direction, Zhao Qingtian threw his mind on the condensation of the poisonous wood imprint.

In addition to the two poisons contained in his mana, he also found the four strongest wood attribute poisons, combined with the secret techniques in the Holy Poison Gong, and created a poison wood mark that matched these six poisons, replacing all the original wood marks in his body.

Then, with the help of the poison wood mark, the mana of the flesh body was easily integrated into these six poisons, and then Zhao Qingtian improved the Spirit Gathering Array, so that when he absorbed the aura, he could also replenish the toxins in the mana.

After everything was ready, Zhao Qingtian gave Du An a jade slip, and after the latter informed Lu Kun, he entered a state of retreat, and he wanted to rely on his ability to enter the bone treasure stage.

......

A large amount of spiritual energy and poisonous gas entered Zhao Qingtian's body through the poisonous wood imprint, and the six poisonous mana of the physical body were replenished, and then Zhao Qingtian transported it into the bones through the blood, and converted the physical mana into bone mana crystals in a ratio of four to one.

At the same time, he used the secret technique of ten poisons in one, fusing six different toxins in the bones, and the toxins led to the condensation of the mana of the flesh.

In the physical cultivation of the Great Perfection of Quenching the Body, the mana of the physical body is twice that of the ordinary Great Perfection of Foundation Building, and Zhao Qingtian's mana is even more refined, coupled with the assistance of the secret technique of the integration of the ten poisons, the condensing pill and melting the bones are almost extremely smooth.

As the toxins and mana crystals condensed in the bones, Zhao Qingtian gradually felt the changes in the bones, in addition to the enhancement of the material, the attributes also changed from the original pure wood attribute to the six-in-one poison.

Over the past year, the nails of his two hands have also faintly appeared with a dark green luster.

Zhao Qingtian felt all the changes in the breakthrough process, and was full of confidence in the future path, and his spirit reached an unprecedented highest state.

"Master once said that after the Bone Treasure Period, we will embark on different paths!"

"If Master's physical body is a thunder attribute magic weapon, then my Zhao Qingtian's physical body is a special attribute poison treasure!"
