Ice Explosion
"Okay, that's enough Angela, if this continues you will be merely wasting energy and the stamina of the beast far surpasses that of your energy storages. You are lucky that it was a beast that didn't have special capabilities and only had simple and direct ways to attack. Otherwise, you would have no chance against it and you have a very big weakness, you are lacking explosive power and if you are facing a being with a durable body and strong defence, you will be unable to harm them much. You can seep your child energy into the bodies of your opponents but this beast had such a strong and large body that it is ineffective against it and in terms of versatility, you are a capable cultivator, but should try to learn a skill with explosive power" advised Lex, who knew that it might upset Angela, especially after all her hard work, but it was something that she needed to hear.
