Chapter 33: Noah's Creation.. Xin Yan's Shock and Worry!
Skipping through further knowledge he got to know about Body cultivators whom he had no knowledge about previously. In his previous life there were martial artists instead of body trainers.
They were generally called warriors, brute and muscle minded people. He had also learned something related to battle ki that they trained in.
Just like Magical power and Qi, Battle was something of low level energy that the martial artists used to gain power.
He learnt Battle Ki as a medium to pass his time along his journey to the top. But now he was grateful to his previous self for doing it, even if it was for fun. To learn this energy he had to put his body through gruesome training and pressure.
'That training helped me in tempering my will, from these records it is the one of the most important things I need for cultivation. Whether it is body cultivation or qi cultivation both need will and patience.'
