Little Shiyou was now stronger than Tian Xuan had been back then. If he received the Beast Soul inheritance, along with the experience Tian Xuan could pass on to him, his Bloodline Power, Sacred Beast Seven-Style Severing Slash secret art, and the Heaven-Devouring Wolf Clan's innate secret arts would all improve tremendously. If he then took another Phoenix Soul Fruit in the future, it wouldn't be impossible for him to surpass Elder Heaven-Devouring Wolf Tian Xuan. Only then could he come infinitely close to the saint level and break free of the Lord of the Universe's constraints.
That was exactly why Tian Xuan had been so excited after sensing Little Shiyou's presence, and why it had sent the Phoenix Soul Fruit to assess him. For some reason, however, the Phoenix Soul Fruit hadn't told it any of this.
If Little Shiyou hadn't happened to use the Heaven-Devouring Wolf Clan's innate secret art, allowing Tian Xuan to sense him, Tian Xuan might still have been kept in the dark, believing Little Shiyou was an ordinary Heaven-Devouring Wolf. If that had been the case, there would have been no need to give him the Beast Soul inheritance.
Tian Xuan knew that only by surpassing it while at the same level—or even far surpassing it—would Little Shiyou have a chance to come infinitely close to the saint level and break free of the Lord of the Universe's constraints.
Once Tian Xuan sensed that Little Shiyou was stronger than it had been at the same age, it resolved to give him the Beast Soul inheritance. In its heart, this was the only chance to break free of the Lord of the Universe's constraints and become a god.
Although Tian Xuan had already vanished into thin air, Little Shiyou belonged to their Heaven-Devouring Wolf line.
