Then he saw a huge bubble spray out from behind the spear demon's rear end.
And he heard the humans around him all bursting into laughter and shouting.
The critical thing was that both the crawling demon and the spear demon seemed very happy, as if burping and farting were particularly joyful acts, and they both seemed a bit tipsy.
The crawling demon said, "This is so much fun."
Finally, they reached the entrance to the sewer, and everybody jumped down.
Out of ten demons, nine kept burping non-stop, each burp producing a huge, colorful bubble.
Even the demons in red couldn't help but laugh.
"We should, burp, meet up with other companions, burp," one said.
With each sentence, he produced two bubbles.
"What are the other companions up to, burp?" Ma Lin asked.
The demon in green replied, "I bet there are lots of groups, each with its own fun. If we head west, there's a chance we might bump into some idiots, burp."
His endurance for holding in burps seemed rather strong.
