After confirming with Vivian that she had received it from an older female elf, Xu Yi immediately asked Vivian to take him to find her.
The answer he received from the female elf delighted Xu Yi.
Because elves had a natural affinity with plants, they understood extremely well how to make use of their properties. Making toys from resin was merely something elves did for fun in their spare time, and was nothing unusual at all.
That answer instantly brought countless possibilities to Xu Yi's mind, so he sought out Elder Elusia again without hesitation.
Originally, Xu Yi had wanted Elder Elusia to teach him the elves' method of melting resin, but he was told that they used a form of magic unique to elves, which humans could not learn at all.
After trying it himself, Xu Yi discovered that this spell really did suit only the characteristics of the Elf Race. Humans had no way of mastering it, so he could only give up.
After some thought, Xu Yi decided to settle for the next best thing. He hoped that the Night Song Tribe led by Elder Elusia would help the Xinfei Merchant Guild build magic machinery for melting resin.
Making the casing for this magic machinery was not difficult, but its most essential component, the magic array used to melt the resin, could only be set up by elves. He therefore had to ask them for help.
Strictly speaking, Xu Yi did have another option: following the methods used on Earth and adding additives and setting agents to a vessel to melt and synthesize resin. However, Xu Yi was unfamiliar with plastic manufacturing. He neither knew how to make these additives nor exactly how to add them. Besides, this method would cause severe environmental pollution, which he disliked.
