The reason Ye Chen had held off on dealing a killing blow to Deidara and his partner was precisely that he was waiting for "reinforcements."
Calling them "reinforcements" was really just a pretext.
Ye Chen could wipe out Deidara and his partner all on his own.
He had refrained from killing them only because he did not want to drag Hidden Jun Village into the maelstrom of conflict between factions.
Once he personally "dealt with" Deidara and his partner, he would inevitably draw the attention of the Akatsuki's members.
Every member of the Akatsuki was more troublesome than the last.
Their leader, the Six Paths of Pain, had even reached the super Kage level.
Being targeted by an enemy like that would be quite troublesome.
Now, Yamato's arrival signaled that the Five Great Shinobi Villages had received the news and come to protect their villages' "future."
Ye Chen was naturally happy to have someone share the enemy's fire, and this was precisely the outcome he wanted.
After hearing Granny Qianyin describe the situation "outside," Ye Chen said bluntly:
"Granny, I'm going to let Deidara and his partner leave next."
"Just help intercept them so they can't slip into Hidden Jun Village while they have the chance."
Granny Qianyin said decisively:
"Don't worry. I won't let them take a single step toward the village."
Ye Chen hurriedly added:
"If they don't head for the village, you don't need to act."
Granny Qianyin hesitated briefly, then quickly replied:
"All right."
Ye Chen focused his gaze on the two men inside the Kamui Domain.
His tone was serious as he said:
"I have no intention of offending the Akatsuki. You forced me to act."
"Now, Elite Jonin from the Five Great Shinobi Villages have arrived to provide support."
"I'll let you leave next.
