Beast Control: Become Invincible from the Beginning of a Losing Streak

This is a world dominated by beast control Outside the human world, there are countless planes in the starry sky, including the mechanical plane, the forest plane, the elemental plane, the undead plane, the dragon world... As long as you contract with them, you can become a beast master and summon creatures from other worlds to fight for you! Two years ago, Xu Yi traveled to this world with his system and directly contracted with the Dragon Realm, one of the strongest planes! I thought I would be able to embark on the road to invincibility right away, but the mission of the system is that the more consecutive defeats, the richer the rewards? I'm sorry, we can start the road to invincibility later, but we can't end this losing streak right away...
