Yin and Yang Heavenly Sword

The Yin and Yang Heavenly Sword was a unique martial art skill.

If one wanted to practice the Yin and Yang Heavenly Sword, he should directly take in Evil Qi, make use of a secret method similar to that of the mental cultivation method of one’s Internal Strength, and then smelt the absorbed Evil Qi until it was distilled into Sword Qi without parallel. Finally, stored all of the Sword Qi within his body.

The Yin and Yang Heavenly Sword was made by distilling Evil Qi into a peerless Sword Qi, and after being distilled into Sword Qi, the ferocious properties of the Evil Qi were stabilized and transformed into the lethal force of this Sword Qi.

However, it was not just any type of Evil Qi that could be refined into the Yin and Yang Heavenly Sword. No matter what kind of special technique, its requirements of Evil Qi were extremely high.

The Yin and Yang Heavenly Sword required simultaneously smelting two types of Evil Qi with diametrically opposed characteristics; one extremely yang and the other extremely yin. And even if it was smelted successfully through this secret skill, it could still not be stored in the body to be at your command like true Internal Qi.

It could only be fixed into a particular form. As for keeping it contained within one's tendons and meridians, the key point was that storing Sword Qi within oneself required one's muscles and vessels to have a far greater degree of tolerance and resistance than ordinary muscles and vessels had.

You have to form Extreme Yin Heavenly Sword and Extreme Yang Heavenly Sword and then fuse them.
