It works! We use just enough and loosen the largest rock. After some digging we can enter the cave, and follow Saknussemm's path once more!

This is so exciting! I could actually reach the centre of the Earth!! I want to run on ahead. My uncle is overjoyed that finally I feel the same as him. He wishes he was young again, but he can't run as fast as me. He agrees to let me go on ahead. If I find anything I'll come back and let him know.

Should I run on ahead? Or should I do something else?
