The first thing Xin Feng did to start his plan, was to keep the curse in place by stunning it from every direction.
"Hina! Do you still have that flint and steel with you?!" Maeda was the first and most crucial piece to his plan. The thing is that Xin Feng already knew about Maeda having a flint and steel with her, however, just like in a movie, he wanted to make his strategic plans clear enough for the examiner or perhaps even examiners, to see.
"Yes! The necklace to remember the days we ventured together right, brother Xin?!"
"Yes! That will be good then! Okay! So, here's the plan!" Xin Feng had to speak loud and clear, because he was continuously moving from place to place to keep the curse stunned in place.
"Sakura! You give your knife to Sato, and after that, you and Hina will gather some dry branches and leaves, to place them right around this curse's legs."
