Giving the wristband to Butterfly wasn't a thought that Su Hao had come up with in the spur of the moment. Instead, it was a decision that he had made after careful consideration for two days.
"Let Butterfly be a Sprite Trainer and let it PK at the front line. There are a few benefits to doing so."
"Firstly, safety. A weakling like me won't be exposed to the enemy's attack range."
"Secondly, safety. Even if Butterfly and the others encounter a strong enemy and fall into a desperate situation, I can still save the situation!"
How?
One summon and they'd be home right away.
This kind of unconventional battle tactic wasn't created by Su Hao alone. Many Sprite Trainers did it.
During class yesterday, their instructors had also taught them that it was safe and reliable to set up arrays in the '1, 1, 2' mode.
An investigative soldier scouted ahead.
A Sprite Trainer was a distance behind.
