The Foster Parents

According to Fei's words, he was a member of Xuanbing Academy, and his achievements today were all given by the academy and teachers. Therefore, Xuanbing Academy must be rewarded. And this return, please entrust Elder Yade.

Because Lingchen Cave was given to the earth elves to settle down, they couldn't often lead outsiders to practice here. Therefore, Fei asked Elder Yade to provide Xuanbing Branch with Tianling Silkworms and Earth Silkworms for the students of Xuanbing Branch to practice on time.

Because Tianling silkworms and ground silkworms were originally cultivated by earth-type elves, artificial cultivation was naturally more efficient than growth under natural conditions. Therefore, Elder Yade agreed without thinking.

However, because the Xuanbing Branch was far away from Lingchen Cave, there was a small episode in the question of how to transport it.
