In the Tian Yuan world, there would be several Great Emperors in every generation. For example, for super family clans like the Shentu family clan or the Lin family, the number of Great Emperors they had was not limited to one.
Take the Myriad Empyreal King, who was killed by the Shepherd Boy, he was considered average in strength amongst the Great Emperors.
As for the Shentu Patriarch, the power he possessed was frightening. When the Shepherd Boy was at his peak, he had borrowed from a Divine Lion from the Nether World Desolate God, and in the end he was barely able to heavily injure the Shentu Patriarch, failing to kill him.
As for the Shepherd Boy himself, he had been hit by the Shentu Patriarch's Death Heavenly Revolution, with the injuries lingering to date.
However… compared to the ancient Great Empress recorded in the books, the Shentu Patriarch was nothing.
