Alvaro and Iliana have not been able to destroy the cave wall. They didn't even manage to send a signal to their parents either. They feel trapped in a space and time.
Alvaro tried his best to destroy the stone wall that closed the door of the Cave. He used an ax to destroy it. Even his strength was starting to drain away and he needed a nutritional intake in order to increase his strength.
"I believe that this wall will surely collapse! And I can get out of here." Alvaro said confidently and then he with all his might smashed the fruit wall. He used his own power without the help of his inner strength.
Alvaro sweat profusely while trying to destroy the walls in the Cave to get out.
On the outside it looked like Iliana was testing her strength but in reality she was blown away even further. He was trying to send a signal to Monica, his grandmother. But in reality he couldn't do all that.
