It should be noted that Dream Island is the only place in the world where this vaccine is sold, and except for the Chinese market, where it's priced at 2000 RMB, the rest of the world sees the vaccine priced at a staggering 2000 US dollars each. Thus, in order to save their lives, pet owners can only spend this huge sum on their pets, which naturally brings enormous benefits to Dream Island. However, this time the profit was the largest ever; in the future, the product's profits will decline year by year, after all, the number of new-born pet dogs each year is incomparable to the existing population.
