"What are you doing?" Lennard asked curiously as he approached William, who was sitting on a small mound that had survived the storm.
On the small mound, William was carving something on a small piece of wood as he watched thousands of people leave for Grenscar.
"Trigger." As William carved the wood with a small chisel, he answered Lennard without looking up.
"Are you sure you really want to do this?" Lennard asked, frowning. From the beginning, William had wanted to personally explode the Atite crystals in the cave. It gave him a headache to think that William, who was still an official rank mage, would undertake such a dangerous and risky job. He had seen how genius William was, so he did not want him to participate in risky jobs.
As a third-rank wind mage himself, he was well-suited for this job.
