Li Mohun passed through.
He traveled to the Cretaceous Era and became a Marker. Who knows what era this was, but there were six strange genders. He specializes in providing pheromones to those omegas who are in urgent need of alpha pheromones. Since omegas are very easy to become dependent on the alphas that provide pheromones, the profession of labellers began to appear at this time, specifically serving the nobles, looking for alphas that match most of the omega pheromones at about 60%, which will neither make the omegas disgusted nor have too much dependence.
Li Mo just wanted to be an unknown markmaker. He never wanted to start a noble business. How could he have such an easy chance?
