He cultivated the Present Gods and Buddhas in one go.
Xiao Kongtong was amused as he listened and knew that this was Master Siren's idea of a joke.
How difficult was it to master the Heart Sword Technique?
He had cultivated the Heart Sword Technique at his Teacher, Bazhun'an's sect. It was placed at the bottom of the list and could only be practiced when an Ancient Swordsman had matured.
There was no other reason.
A person's imagination was limited by their 'vision' and 'cognition'.
If you want a child to start to practice the Heart Sword Technique from a young age, what would he be able to visualize? It would probably be illusions of some large toys.
However, after one became a Sword Deity, one could then visualize their own Present Gods and Buddhas. The 'self' that could be chosen and modified would be really too much!
However, there were no absolutes in the world, for example, Master Siren.
