Zhang Chi believed that the Hand of the Heavens, being in the middle of the situation, would find it difficult to realize this point. Even if the Hand of the Heavens did figure it out, he might not be able to make the right decision.
Therefore, this poisonous scheme could stabilize the Hand of the Heavens and prevent him from acting rashly and recklessly.
Now was not the best time for a grand, decisive battle for the Hand of the Heavens, nor for Wenren Li.
Zhang Chi did not wish to engage in battle with the Hand of the Heavens at this time, in a situation where playing for time means certain victory.
This poisonous scheme would allow the situation to continue smoothly and also accelerate Wenren Li's growth.
But indeed, it was too poisonous.
The toxicity of this strategy lay not in how many people died but in the heart that concocted such a plot.
In warfare between two armies, death and life are common affairs.
