First of all, the ancient Buddha with burning lamp said these words because the Monkey King resisted the Tathagata, and the Tathagata was ready to punish the Monkey King in a rage, so this time, the ancient Buddha with burning lamp appeared to intercede for the Monkey King. In fact, both the ancient burning Buddha and the Tathagata understand that the Monkey King is not a rustic person, and the reason why he is so bold is also for the sake of the Dragon King. So having such a disciple is actually a very rare thing, but the Monkey King's expression is lacking.
Secondly, the Monkey King, as an anti-Buddha fighter, has made great contributions to exorcism. Moreover, in the future, the Monkey King will be needed to make contributions to Buddhism and Heaven, and to the Lebanese people in distress. And the Monkey King's mind is pure, just want to uphold justice for all kinds of injustice in the world. It is very rare to have such a right-hand man. You can't hurt Wukong's heart of justice because of a little thing.
Finally, the Monkey King must exist. After all, the Monkey King is the most important boneless relic. It not only shoulders the task of overcoming lawlessness and maintaining peace among the three realms, but also needs the Monkey King's original body to help the Tathagata Buddha return to the Buddha country to uphold justice. So to sum up, although the Monkey King's words will offend people, he is capable and just. I believe no one has the heart to punish the Monkey King excessively.
