Tree demons were all individual entities, so how could they become a whole? In this world, no method would work. Even Zhao Hai could not do it. He could command the tree demons to attack like an Army, but he could not command the tree demons to group together. Zhao Hai could not do that.
Zhao Hai sensed the power of universal law from the Treant. However, the power of universal law had been used before, which meant that the Treant had used the power of universal law. After seeing that it was composed of many tree demons, Zhao Hai immediately thought of a possibility, that the Treant was actually a tree demon who used a special power of universal law to combine many tree demons together. It was a powerful combat collective that was produced by the concentration of its abilities. However, this Treant should only be commanded by the Treant who had used the power of the law.
