Does Master Ganther mean to draw out this strand of mysterious energy and attach it to the sword?
Clearly, the key to the fourth training task—the 'One Hour, Thirty Coastal Madness Fish Kill'—lies in the master's words.
Thus, Rein, at the bottom of the sea, tried to mobilize this strand of mysterious energy within him to his Glimmering Greatsword.
When he focused his consciousness on the mysterious energy, there was indeed some effect; the energy started to move from within his body toward his arm, only it didn't completely heed Rein's command.
Once it reached his arm, it became disobedient and circulated back and forth instead.
This was like a child in a rice paddy, strenuously trying to catch a slippery and strong eel; despite all his efforts and using all his might, he could only grab its tail and failed to pull it out of its hole.
Rein fell silent.
