Just a quick glance by the boy 

the whole crowd that were eating melons became catatonic as they fell on the ground with foam on the corner of their mouths their bodies began to spasm like crazy

some people began to bleed from every orifice some bulges began to apear on their bodies like huge insects are walking inside their bodies 

but all of them had one thing in common 

their lips were converged into an strange gentle smile that put out weirdness and insanity as nobody will have a gentle smile while in this condition

the only ones that didnt fell down were the trio bvut that doesnt mean that they were spotless

Ye Mei was still up but she was trembling some bulges apeared on her arms and they were moving like some sort of giant insect her eyes were bleading black blood? that was exuding a strange aura

Sister Liu was standing her body trembling as she bleed from every orifice a kind of golden blood that was full of tiranic aura 

the only ok person was the black haired woman that only had a nose bleed but her eyes were unfoucused like she was in the dream land 

soon the body of the crowd began to distorce 

their limbs were twisted some tentacles began to apears on their bodies 

some flesh grew on their bodies making them an abomination of flesh and blood 

some began to get inhuman features like tall eyes or abnormaly wide mouths 

their skin collor began to change 

some humans began to get animal or creatures features like fish some began to get features of fantasy animals like slimes but they were just parts they didnt turned into slimes so it is strange 

most humans if they can still be called that began to stand up and atack each other 

they began to use their new organs to figth and the distorced flesh and strange collored blood began to stain the floor of the plaza
