Traveled a Second Time and Became a Human Spirit

As the Lord of the Source Realm, holding the Ring of the Creator, Zou Si has the power to rival the Creator God... But his power could only cover the Source Realm, so he tried his best but couldn't find a way home... Finally one day, a voice found Zou Si and told him that he could help him return to his longed-for hometown, but the requirement was that he must respond to the call from himself, and the name of this voice was - Human Will (Alaya). As an otaku, Zou Si naturally knew what Alaya was in the Holy Grail War, so he didn't pay much attention to him. However, Zou Si, who couldn't find a way home at this time, could only try him to see if there was any hope of returning home... Then in the Fourth Holy Grail War, when he saw Lancer Uchiha Obito and Saber Artoria fighting together, Zou Si understood that this Alaya was not simple.
