Where's the Promised Animal World?

[MTL] Nan Hehua unexpectedly traveled through time And transformed into an egg.
Fortunately, he broke out of his shell on the first day of his time travel and surrounded by... two male dragons??
Nan Hehua thought he traveled into the dinosaurs age. Every day he happily rubbed against his father and brothers, rolled in the mud and ate with blood in his mouth. From time to time, he would rub against all the little dragons in the tribe.
Until one day, his two fathers turned into humans in front of him...humanoid?!!
What he originally thought the dinosaur age was actually an assessment environment set up by the Interstellar Monitoring Agency to examine the patience and parenting skills of adoptive parents towards orphans to be adopted. Not only that, to ensure fairness, this is being broadcast live across the entire galaxy.
