The Water Arrow Technique and Water Shield Technique are the only two magics Duke can rely on now. The level of these two spells is very important.
If it were on land, the remaining one month would definitely not be enough to grind these two skills to full level.
He is only a Level 3 Wizard Apprentice now, and the Magic Power in his body is too little.
Even if he uses up all his Magic Power every day, it's impossible to grind these two skills to full level before the assessment.

During this period, he also purchased a piece of information that recorded some common types of Deep Sea Magical Beasts and provided a simple description of their strengths.
