How did the beast egg of Hunluan end up in the hands of the mortal? To be precise, at the possession of the old marshal?
The answer to that is simple. The beastman, who was supposed to be carrying three pairs of eggs and was on his way out of the building with his comrades, decided to split the eggs among them and escape via different routes.
Among these people, one is an undercover agent from the human race, and the other was killed, so the eggs of the two wardens were secured by the two systems to be placed in their master's small world for protection. As for them, they were secured by the only alive beastman among those who had sneaked in and were safely delivered to the leader of the beastmen race.
