Beast-Taming Awakening for All: Crafting a Three-Star Five-Cost Unit

After a nap, Lin Feng looked up. He saw his teacher at the podium, teaching beast-taming with a gigantic three-tailed fox right beside him. Wasn't he preparing for the college entrance exams? How had he suddenly transmigrated? Everyone thought his Golden Shovel was trash when it awakened, but he found all sorts of ways to use it. Combine three copies to make a three-star, five-cost unit. To advance each rank, he needs to raise another spirit beast with a different attribute. In the end, he can combine them into an army of fifteenth-rank spirit beasts with every attribute.
