Although allowing Elder Sword to maintain the sword net required Elder Jin Kai to continuously consume spiritual power, compared to the troubles caused by the pale golden Silver Corpse, Elder Jin Kai preferred to maintain the sharing of spiritual power with Elder Sword.
Maintaining the sharing of spiritual power with Elder Sword, and the spiritual power consumed in sustaining the sword net, was much less than the spiritual power consumed by the pale golden Silver Corpse in summoning a large number of Silver Corpses, not to mention that it didn't drain the spirit.
However, when encountering ordinary Silver Corpses, Elder Sword didn't need to take action; his only role in the team was to quickly eliminate any pale golden Silver Corpses that appeared.
The pale golden Silver Corpses were equivalent to the Great Elder Level and possessed extremely high wisdom.
