Su Yang's current priority was enhancing his foundation.
The foundation referred to the capacity of his energy channels.
It was akin to a waterway, with power being the water flowing within.
No matter how vast or abundant the water source, if the waterway was not spacious enough, it could not hold the water. Even worse, if the water source was too great, it could burst the waterway.
The relationship between power and energy channels was such that if the energy channels weren't capable enough and too much power entered, they would shatter. By then, Su Yang reckoned he'd likely explode and die!
Therefore, he had to increase the capacity of his energy channels. To do this, he needed to use the secret techniques of both Buddhism and Taoism, by absorbing the spiritual energy from the outside world.
The method Su Yang had previously used to absorb spiritual energy was to draw it from the converging points of geomantic treasures.
