He returned to his human shape and started working on the tools and materials in hand to make large batches of arrows. Just after minutes of beginning forging, he heard loud booming sounds coming from the direction of the monsters.
"You've started," he muttered before returning to focus on the task in hand.
It took him five hours to make twenty thousand arrows. His efficiency in forging was increasing with time, especially when he became so familiar with the arrows he was making.
As for his system and golden dragon, they finished arranging everything in two hours and waited for him to finish.
"I'm ready," he turned into a dragon and soared towards the monsters.
When he reached there, he found the pillars surrounding the area of monsters with some scattered inside. From his high place he could take a glimpse over the shape of this arrangement.
"A flower formation?" he muttered.
