They depended on each other, eventually established a family, and raised four children. Among them, Shadowfang, the strongest gray wolf, became the hope of the family. Under the leadership of Shadow Fang, the snowy tribe gradually grew and migrated to the warm grassland. As a candidate for the new generation of wolf king, Shadow Fang showed extraordinary charm, but he had strange feelings towards the intruder Ye Zi.

After a fierce battle and half a year of hard work, Xiaoyue won Ye Zi's heart. The two overcame many difficulties, and Ye Zi joined the Snowland tribe and became an outstanding male wolf. He partnered with Shadow Ya and gave birth to Niu Hulu.
