Wasteland Beasts from Earth Lizard to Earth Dragon

Beast control in the wasteland, no system, no time travel, no heroine, no wisdom Qin Zhen, a poor student, accidentally got the beast-taming notes of a boss from another world and began to rise as a beast-tamer. The road to rise was not smooth, and his character was gradually distorted, revealing a corner of the world: Is this a wasteland world or a beastmaster world? What beast can you control if you don't have money? Don't think that 9 gates mean you are not good at controlling beasts. Talk to my earth dragon, we are all working hard to survive, what, you didn't buy animal protection insurance? The historical text is missing, and the culprit saved the world? Whoever explores history will be eliminated? S can't produce A as king? Are humans also beasts? Where are you going? Invincible under heaven? Enemies from heaven?
