When the two entered the depth of the cave, they saw a safe which they estimated to weigh a ton.
Without a doubt, it was the goal of their journey.
"A safe? Do you know the password?" Chen Zhao asked.
"No... Why would I know the password?"
"Then let's pry it open," Chen Zhao suggested.
"Will the mattock work?"
Chen Zhao took the mattock and tried to open the safe. However, the mattock broke straight away.
It was clearly impossible to open the safe with a mattock.
It was even more impossible to carry the safe back, since it weighed at least one ton. Even if Chen Zhao could carry it out of the cave, he would not be able to walk so many kilometers across the mountains with it.
The only other option was to carry it back with a helicopter, which was also impractical at the moment.
All in all, they had to attempt to open the safe on the spot and then share the treasure.
