Of course, Chen Yu did not understand the hieroglyphics of Ancient Egypt, but that did not mean he could not preside over the rites and rituals of Osiris.
The rites and rituals to worship the deities should naturally be presided over by a priest, but if it were a noble or royal bloodline, they could also take on the role.
In fact, in Ancient Egypt, the priests of the deities were themselves drawn from the nobility or royalty, and the Pharaoh himself claimed to be a Child of the Sun God, making him the best candidate to preside over the rituals.
Moreover, a Demigod can certainly be considered of noble bloodline, even if Chen Yu was not an Egyptian.
Besides, even if they wanted to find a true Egyptian to preside over the ritual now, it would be impossible, for the Ancient Egyptians had already perished along with Ancient Egypt due to the Arab conquest. The Egyptians living today are mostly descendants of Arabs, not the true Ancient Egyptians.
