In the Blackstone Slums of the Beast Taming Era, Lin Chen was a "useless beast tamer" ridiculed by everyone—his mental power was mutated, and he could only contract a broken-tailed scorpion, making even survival a problem.
Until Zhao Hu and his hyena beast came knocking, nearly killing him, he activated the "Desire Visualization System": it could see through the desires and weaknesses of all living beings! The tailless scorpion craved metal to repair its body, the hyena beast tore at its prey madly for a reward, and Zhao Hu was obsessed with a map of a mysterious nest...
From then on, Lin Chen put away his cowardice and transformed into a cunning chess player: using metal scraps to lure the scorpion with a broken tail to set a trap, using false information to make the enemy kill each other, and using the bond of desire to evolve the useless beast into a ferocious beast of the abyss!
When the Heart-Eater uses the power of bonds to create war machines, and when the beast of desire beneath the abyss is about to awaken, Lin Chen, holding the evolved mechanical scorpion, the abyss shadow falcon, and the ice golem, sneers: "Want to control the world? Get past me first!"
This is a story of scheming to rise up against all odds, using desire as the helm, and ultimately saving the Beast Taming Era—your weakness is my capital to defeat you!
