Shi Tian was slightly taken aback by Mary's request to detach his mechanical right arm at first and the subsequent modifications she made to it.
The arm, which she returned to him, felt slightly heavier. It now had a small compartment and what appeared to be a modified emitter.
Truth be told, Shi Tian didn't know what that modified emitter was until Mary told him to charge the Light Beam.
Everything started to make sense to him, but it also made him question something.
"Wait a minute, so all along, the mechanical right arm wasn't even in its final form?" Shi Tian asked in shock.
"I had charged a Light Beam before in the past, and its power was strong, but definitely not enough to be louder than the current sound in the battlefield. So how strong is this emitter?" He enquired, seemingly curious about it.
Naturally, he would be curious about the modification, considering that he was walking in the path of a mechanic.
