Don't think he is a stupid pig monster! He is the silent nuclear bomb of the three realms that has held the Tianhe Gate, swallowed the Yin Rod, and withstood the catastrophe!
Dongwang Gong's "Pig Swallowing the Moon" world-destroying situation: Guanghan is the gate of the Moon Cave, Chang'e is the soul key, and only Canopy can open the Tianyuan Divine Valve with blood. However, he carried the "Navy Nuclear Button" (Xian Jie) and held a rake made of Dayu's Yin Rod (the root of the tooth was engraved with "Kill Chang'e first"). He acted out "Teasing the Fairy" and defiled himself and was demoted. He was mistakenly cast into a pig fetus to guard the Tianhe Flood Discharge.
The reason for shouting "separate luggage" on the way to get the scriptures is because they are afraid that the Jade Emperor will send a substitute to open the gate, and they pretend to be "afraid of water" to reassure the heaven.
The Tathagata named him the "Purifying Altar Envoy", which actually allowed him to swallow black materials from the three realms. When he patted his belly and said "I'm full", it was a declaration that "the evidence of all the negative information has been extinguished".
In the pig pen of Gao Laozhuang, there always lies the one who lives as a safety valve for the three realms - the silent nuclear bomb!
