Mu Yuan's decision to evolve Dead Bone was a well-considered one.
He immediately ruled out the option of evolving all the Little Skeletons. Considering most of them were only at level one or two, their combat abilities wouldn't be significantly enhanced after evolution.
That was mostly due to his financial constraints.
Even though his daily income of Soul Sand had exceeded 300g, he still couldn't provide uninterrupted training for all types of soldiers. He could only prioritize the cultivation of his trump cards and main forces.
Bone Three and Bone Four, among the first batch of skeletons, had reached relatively high levels, generally around LV4.
They were already proficient in skill energy manipulation, and it wouldn't take them long to learn the spear-throwing skill after evolution. He would be able to quickly muster an army with long-range attack capabilities.
However,
Mu Yuan still chose Dead Bone.
