I trained the whole day and slept at midnight, Hydrae didn't stop me, until it sensed that my psych energy became low.
The next day, Hydrae woke me up reminding that it was my second day and I shouldn't be here tomorrow, I should be up at the shore by then.
So I trained once again, I tried the water ball barrier being offence and defence, it succeeded, then I tried the water whip, which was pretty cool, it took a moment for me to get the whipping right, I actually added a frozen sharp tip at the end of the water whip to make it more deadly.
Hydrae continue to nod at my showcase of self-taught skills, because it didn't teach me anything, but then I realised, instead of getting frustrated with Hydrae, I should just ease my frustration and learn for myself, don't be independent of the Holy Beast.
