If You Don't Control Animals Scientifically, You Are Not Being Serious, Right?

I just slept soundly in class, but when I opened my eyes, the world was completely turned upside down. Alien beasts are rampant in the world, undead are roaming everywhere, dragons roar in the sky, demons are causing chaos, and even the mythical Bull Demon King has appeared in the world. I thought that when I stepped into this alien world, I would be able to embark on a cool road to control beasts, but looking at my contracted partner, Ye Yan fell silent on the spot. Others are majestic in their beast control, but what the hell is a sheep in their own control? What's even more outrageous is that this little sheep is a narcissist and shows no signs of being serious at all. Even the bound system has a strange style, and each task assigned is more bizarre than the last. Ye Yan was filled with frustration and couldn't bear it anymore. The system made a faint sound: the mission reward was doubled directly. The boy's face changed instantly and he smiled: Hehe, it smells so good! Since then, one person and one strange little lamb have been wandering together, riding on a giant dragon to frighten all directions, crushing angels with force, beating up a group of demons, and overthrowing the heavens along the way...
