Zhao Hai wanted the orc Army to join the battle so that they could familiarize themselves with the battle outside as soon as possible. After all, it had been a long time since the orc race had participated in a war like this. Of course, Zhao Hai would not let them join the battle without any preparation. That would be equivalent to sending them to their deaths. They had to enter the realistic illusion to train for a period of time before joining the battle. Only then would they be able to be useful.
Furthermore, Zhao Hai discovered another advantage of the beastmen race. They had an advantage that other cultivators did not have, and that was their fertility. The beastmen race's fertility had always been very strong, while the cultivators 'fertility had always been very low. Their small population had always been Zhao Hai's biggest headache. The beastmen race could solve this problem.
