Although Zhang Yanhang previously mentioned he wouldn't use spells, he had just obtained this new ability and felt the need to experiment with it, so, in the end, he still used spells a few times to kill monsters.
Of course, since the Spell List contained attack spells that were capable and relatively normal, Zhang Yanhang actually used the Frost Freeze Beam throughout the entire process. He had now become quite skillful at operating the Frost Freeze Beam.
Initially, Zhang Yanhang was worried that the spells in the Spell List might not be usable after their two free uses were exhausted, but he later found that as long as he was willing to pay the Energy Value himself, even if the free uses in the Spell List were gone, he could still launch spells as usual.
Moreover, Zhang Yanhang also mastered a little trick; that is, when outputting Energy Value, increasing the output would similarly increase the power of the spell.
