When the celestial Court deployed its troops, Sun Wukong was not entirely clear about the strength of the celestial Court, but he knew for sure that he, a mere mid-stage Great Luo Golden Immortal, could not withstand them alone.
Thus, Sun Wukong made many preparations, not to eliminate the Immortals from the celestial Court who were invading, but to paralyze them.
After all, he could not let these heavens' Gods and Buddhas know that he was already aware of the cause and effect.
Not only would this be detrimental to his senior brothers behind him, but it would also bring him no benefits.
Therefore, he had to display his desire to resist, to numb the thoughts of his opponents, hence he devised a plan within a plan.
And these were just the initial steps of defense.
To disrupt the celestial Deities' view of him and also to slightly trouble these celestial Deities.
To convince these celestial Deities that Sun Wukong truly intended to rebel.
