The fight went on.
Su Ping was swallowed by the undead lion, to later resurrect again and again. He tried his best every time. His attacks became increasingly faster as he approached his limits. Although still unable to cause damage to the undead lion, he was getting accustomed with quick outburst attacks.
Later, Su Ping simply stopped merging with his pets, letting them join the battle, so that they could also grow too. Once the fusion with his pets was dispelled, the battle became even more challenging for him. However, he gradually figured out a way for him to keep up with the undead lion, and he reduced the blast effect with his small world.
The undead lion seemed to know nothing except killing. No matter how many times Su Ping resurrected, it simply killed him again and again.
