Eren understood that he could not complete this mission that was given to him by the sect master with the help of ten weakest disciples alone.
It would still be possible if he had a Core Disciple in the mix, but that wasn't the case either.
He couldn't even use Ye Liang who accompanied him as a servant on this trip. Hence, this mission was no different than sending the ten outer disciples to their deaths.
During the journey, he had been thinking about various ways he could help them succeed, without actually fighting in their place or taking another person's help.
Fortunately, he did manage to think of a decent method that fit the criteria of the option he had chosen.
"Elder Ren, the formations are active," one of the ship's crew members reported. "Should we break it?"
Eren looked back at the ten disciples, not answering the crew members.
