In fact, the outcome was quite similar to what Zhou Tian had anticipated.
Originally, how Pan Shi had planned it was not mentioned, but when Zhou Tian released his clone Beastmen, they indeed managed to kill off most of the Fake Pan Shis in a very short period of time. Although there were some who slipped through the net at that time, compared to the previously chaotic situation of thousands of Pan Shis running around, the scenario of Zhou Tian now rounding up about a dozen Pan Shis looked much better from every aspect.
At that time, Zhou Tian didn't give Pan Shi much time to flee, as the longer the time passed, the more unfavorable the situation would become for Zhou Tian. After all, Zhou Tian didn't know if the Pan Shi within his sensing range were actually mixed with Pan Shi's true body; thus, without a way to confirm the true identity of Pan Shi, Zhou Tian would certainly need to prepare more time for achieving his purpose.
