سوال صعب في القصة

[Rezk]

Because they had followed the path to its end and there was no way in the huge cave only to cross the sea to the other side and complete the journey to the center of the earth.

if you flashed back in chapter 2 when Axel told his uncle about dangers of the journey , the prof. replied

"we are scientists and we should go there and see for ourselves"

so he wants to see what is on the other side and there was no other way to continue.

ممكن نقول Because he was corious (يعني محب للالستطلاع)

[محبة العلم]

[Hesham Shafek]

In my opinion , he wanted to learn more about any thing under the ground and continue to the center of the earth

i agree with Bassem

[snow angel]

in my opinion :-
because he was scientist fond of exploring , there was no one explore it before so there was no information about it, might he couldn't enter the centre of earth again so he was wanted to collect the biggest amount of information and he was must cross it to could continued his journey
