However, he only felt a slight heartache. Zhao Hai had seen too many deaths. In the lower realm, he probably couldn't even count the number of people he had killed. Hence, he quickly suppressed this feeling.
He knew why he had this feeling. First, it was because he treated these undead creatures as humans. Second, it was because there hadn't been any large-scale battles since he arrived in the cultivation world.
Zhao Hai took a deep breath and calmed himself down. He then pretended to command the undead creatures and ordered them to get into battle formation to fight against the elven Natal spirits.
The undead creatures released by Zhao Hai didn't form a battle formation. Instead, they swarmed forward like a swarm of bees. Zhao Hai didn't want the elves to notice anything, but he couldn't do that now. If he didn't command the undead creatures, they would all die. At that time, the round King Kong and the others wouldn't be able to stop the elves 'attack.
