First... create an opening!
Leaping into the air, Chiba had already made up his mind. One hand rested on his sword as he looked at the Masked Man still some distance away. He flung out the two smoke bombs he had prepared, sending them crashing into the ground between them. They exploded with a bang, instantly swallowing his figure.
At the same time, as he watched the Masked Man's figure vanish behind the blue, purple, and white smoke, Chiba's thoughts began to race.
At this moment, he was finally certain that Obito had his own plan. It was definitely not as simple as setting a trap to eliminate him.
Though he still did not know what that plan was, it required Obito to stall for time again and again.
Now, it was no longer Chiba who needed to stall for time—it was Obito! In other words, stalling now benefited Obito, not him.
He could not wait any longer. He had to end this conversation, and because the situation had changed, he also had to end this battle and hurry to Kushina and Minato Namikaze's side! Obito was no longer the Obito from the original story. With that as the premise, his previous thoughts had been far too simplistic.
He could not rule out the possibility that Obito was deliberately doing the opposite—that Obito knew Chiba wanted to stall for time, so he intentionally acted as though he too needed to delay things, making Chiba think, The other side must have some scheme that requires time. If I keep stalling now, it will only hurt me. That could make him rush to end the battle and head for Kushina and Minato Namikaze, thereby falling into some scheme. But compared to risking stalling time for someone else, only to ultimately be outmaneuvered
