In the World of Royal Pets, I Win with Quantity

When Lin Fan opened his eyes, he saw a gray crystal in front of him and comments of pity or ridicule around him. "He is the one with the highest theoretical score in the grade. It's a pity..." "My mental strength has not even reached the level of being able to control a strange beast. I am destined not to achieve any great achievements in the future." But Lin Fan turned a deaf ear to these comments, just because his golden finger came. "Ding, the memory integration has ended. Congratulations on awakening the interstellar Zerg system. I wish you good luck!" Lin Fan looked ecstatic. It doesn't matter if he controls one strange beast. I can control 75 of them now! I heard your Black Rock Dragon is awesome? Say it to my millions of Zerg!
