Trying to catch Shadow Squid in the sea is not an easy task; otherwise, the Shadow Squids in the waters near Academy Island would have long been caught by the Wizard Apprentices.
Duke thought for a moment: first, he needed to solve the problem of underwater breathing.
Even with a Great Knight-level physique, it was nearly impossible for him to hold his breath and complete the process of capturing a Shadow Squid.
Wizards have several methods for underwater breathing; one such method involves a type of seaweed called Mandev, which enables underwater breathing just by holding it in the mouth.
However, this seaweed is very expensive, even surpassing the value of the Shadow Squid itself, which Duke could not afford.
Duke planned to use a magical technique from the "Basic Theory of Water Element," a magic known as Underwater Breathing.
This magic is just a secondary-level spell, with a complexity of just N2, appearing quite simple.
