If possible, the best choice is naturally space-based psychic power.

However, this kind of spiritual energy involves some kind of essence of the world, and there is no method to cultivate it at all. Even if there is, it is kept secret by certain powerful people and it is impossible to bring it out.

Even if it is brought out, it may not necessarily allow future generations to follow the path of their predecessors and achieve results in cultivation.

Space-related psychic powers are something you can only encounter by chance.

Then Chu Yao could only settle for the second best and choose other types of spiritual power.

wind.

fire.

thunder.

For the form of wings, these three attributes are the most suitable. The thunder in the sky stirs up the fire on the earth, and the wind is used as a medium to cheer, so the lethality can be guaranteed.

Then the next step is to choose a technique.

Chu Yao himself and his clone Liu Fang stayed in the library and read through all the three types of spiritual power secrets currently stored in the library.

It took three full days to select the most suitable technique.

There are two kinds of exercises.

One is called "Wind and Thunder Wings".

This technique was captured by the human race from the alien race. It is a training technique specifically for wings and is the origin of the alien race "Thunderbird Clan".

This race was exterminated in the war a hundred years ago.

The two most precious treasures in the clan, one is the crystal core of the origin of lightning, which was robbed by the Black Lotus Evil Saint, and the other is the origin of the martial arts "Wind and Thunder Wings", which was taken into the possession of the human race.

Chu Yao had seen the Black Lotus Evil Saint before, and there was still a wisp of purple lightning in his body. Because of this reason, Chu Yao felt that this technique was destined for him.

…

Another martial art he chose was the "Eight Styles of Xunli".

This is an extremely ancient martial art of the human race. Xun and Li are both in the Eight Trigrams. Xun represents wind and Li represents fire. Wind relies on the power of fire and fire helps the power of wind, so they complement each other.
