Dylan started the necessary calculation. There was still something he didn't understand about the numbers.
- This is not right! There must be something missing.
- What else is missing?
- I don't know but I think I will figure it out soon.
- What should we do to help you?
- Just keep quiet and let me finish my calculations.
Dylan was too concentrated to the point that he didn't notice the drop in the water level until the boat hit the ground.
At that moment he looked around with a confused face:
- What's happening?
Tarou was the only one remaining beside him:
- The sea is backing off and the island began to appear again.
- Why you didn't tell me that sooner?
- Did you forget? You asked us to not say a word to you.
- Where are the others?
- They went away for a walk to not disturb you and I stayed here in case you needed anything.
