Prehistoric: Accept the Three Pure Ones, Tongtian worships me as his father

Travel to the prehistoric world. Lu Tianxing awakened to a whiteboard system. A system that has no other function other than being able to display his personal attributes. Simply outrageous! Just when Lu Tianxing was almost in despair, a voice suddenly came from the whiteboard system in his mind! "Ding!" "Congratulations to the future son of the host. Taoist Taiqing has sensed the arrival of the host and is rushing at full speed to strive to activate the good relationship between father and son with the host." "Ding!" "Congratulations to the future apprentice of the host. Taoist Yuanshi has sensed the arrival of the host. He is coming, running wildly, striving for the fate of being a master and apprentice with the host." "Ding!" "Congratulations to the future adopted son of the host. Taoist Tongtian has sensed the arrival of the host, and is speeding up to fight for the fate of becoming a foster father with the host. Sub-causal." After hearing these three rounds of prompts, Lu Tianxing, who was a little unhappy just now, suddenly exploded! What the hell? It’s true that this system is a whiteboard, but it can actually remind me of the opportunity for Sanqing to follow me? Or is it that the eldest brother wants to be his son, the second child wants to be his apprentice, and the third child wants to be an adopted son? Be good. Is this a joke? Lu Tianxing is thinking. Not at the foot of the mountain. Sanqing has started to plead at the same time! "We have been wandering for half our lives, but if my father never abandons me, I would like to become my father, my teacher, and my adoptive father!!!"...
