Chu Xuan was extremely cautious and did not dare to have any carelessness. Even at this time, all the channels, bones and skin on his body would not let him go. He also insisted on the green mountain and did not dare to be slack.

Because he has only one Tianxuan pill. If he fails, he becomes benevolent. He didn't want to miss the eight nine Xuangong, so he could only persist with great perseverance.

There were countless black dirt oozing from his bones, veins and flesh, and finally spilled over his body surface through his pores. However, for three hours, his body surface had been covered with black dirt, at least one finger thick, and the stench was floating all over the hall.

Chuxuan felt as if there was a big hammer hammering his own bones and meridians. There was a blood exchange machine, which was rapidly changing blood for himself. There were tens of millions of ant snakes biting their skin. There was also a big stove burning himself.

It's not only a physical exercise, but also a test of spirit and perseverance. If you relax a little, everything will be wasted.

What's more, a person can only take three Tianxuan pills in his life, that is to say, no one has only three opportunities to practice the eight nine Xuangong in his life. Once he fails, he can no longer practice the eight nine Xuangong. For a monk, it is more difficult than being possessed by the devil.

This is only the first threshold for practicing the eight nine Xuangong.

The second threshold is that if there is a slight error in practice, they will be possessed by demons. If they are light, they will be seriously injured and their accomplishments will be greatly reduced. If they are serious, their bodies will die and their ways will disappear, just like immortal Ziyang.

Chu Xuan didn't want to be defeated. He could no longer practice the eight nine Xuangong, and he didn't want to be possessed by the devil.

Therefore, no matter how painful he is, he always keeps a clear and clear mind, and always pays attention to some taboos of practicing and some tips for practicing the eight nine Xuangong.

After the black dirt was removed from the body, then some white bone slag and red blood beads were eliminated one by one.

It is even more powerful than the original arhat gold body. At the same time, the chaotic gold elixir in the elixir field and the Douzi secret in the sea of knowledge also have reactions.

The two will join together to beat every inch of Chu Xuan's muscles, bones and meridians, so that countless impurities and toxins are discharged from the body, which has no more impurities and toxins.

The most important thing is that with the understanding of the secret of fighting in the eight nine Xuangong, Chu Xuan also understood the mystery of the word "dou". The mutual communication between the two made the product of Dou Zi secret easier, and Chu Xuan's fighting skill gradually became stronger.

The skill of practicing the body of the eight nine Xuangong also attracted the attention of the chaos golden elixir, which made the chaos heaven, which had never made progress, to practice.

In his heart, chuxuan didn't expect that the eight nine Xuangong should have such a function, and at the same time attracted the attention of Dou Zi MI and chaotic golden elixir.

It doesn't have to be said that you have to practice the eight nine Xuangong.

After three days and three nights of suffering, Chu Xuan was shocked. All the dirt, bone and blood scabs on his body peeled off, revealing his ancient copper skin. His muscles were symmetrical and strong, hard as iron, and his bones were like refined iron. The cold light was everywhere and there was a crisp sound.

"Gold skin and jade bone make a great body without scale, but a small amount of Xuangong." Chuxuan opened his eyes, and his eyes were bright and confident. There was an air of arrogance projected from his eyes.

This is the hegemonic power that people who practice the eight nine Xuangong should have. It has a sense of iron and blood, like fighting all the enemies in the world.
