Xiong Li and the rest were extremely excited. They were all shouting and attacking the Zergs. However, their killing speed couldn't be compared to the undead creatures.
The cooperation between the undead creatures was perfect, so the speed of killing the bugs was naturally very fast. However, Xiong Li and the others were practicing, so their speed of killing the bugs was naturally not that fast.
Zhao Hai didn't let Xiong Li and the undead creatures kill the bugs. The undead creatures were under the command of melgen and the others, and their cooperation was perfect. If Xiong Li and the others joined in, they would only destroy this perfection. Therefore, Xiong Li and the others formed a small team and kept killing the bugs.
