The idea of building a biochemical army was good, but Yang Ling only realized how difficult it would be when he tried to implement it in reality!
He had only barely managed to produce three hundred Mandalas after purchasing a large amount of Siberian Gut Severing Plants at a high price, merely enough to equip a little over three hundred self destructing bats.
After consuming a Mandala, the Twin-legged Flying Dragon he had tamed could still move for about a hundred steps before it lost its ability to move. A hundred steps might be very little to an average Magical Beast, but it was enough for the speedy Twin-legged Flying Dragon to launch a fierce counterattack.
