"Teacher Liu, how... how do we rescue him?" Xu Yino asked softly.
"How did this concrete dry so quickly? It's only been a short time, and it's already solidified into a lump."
Liu Banxia touched the concrete, his brow furrowing into a big knot.
When illuminated with a flashlight, it wasn't obvious and seemed just like a lump of concrete. Only after touching it did he realize that the concrete had already dried.
He wasn't very knowledgeable in this area, but he felt it was odd for concrete to solidify so quickly.
"This is a bit troublesome. Quickly find a pickup or a truck; we'll need to take him away with the whole lump. Glucose, does anyone have glucose with them? Quickly let him drink some." Liu Banxia shouted.
"I have some here."
At that moment, a doctor shouted and ran to the car with glucose, leaning in to provide the patient with some glucose.
