Due to the re-adjustment of the magic circuit.
Within half a year, Han Dong's study of [Library] related knowledge became doubly effective while deepening his study of the 'Sand System'.
In Han Dong's view.
'Yellow Sand' is a kind of magic that encompasses everything: offensive, defensive, binding, and seeking out enemies... its power is quite remarkable.
However, there's still a problem.
Energy consumption.
Even with the adjustment of the magic circuit, Han Dong is still troubled by the energy consumption problem when casting all kinds of Yellow Sand spells... If he's not careful, more than half of the energy in his brain would be drained.
If he wants to solve the energy consumption problem... there are only two ways.
First, to acquire a Fate Artifact (or accessory) to help optimize and reduce spell energy consumption.
Second, to break the breed, which would greatly increase the energy limit.
...…
Han Dong exhausted about a sixth of his total energy.
