Shin Uchiha laughed when he heard Shisui Uchiha's words. "Haha, you've improved! This time, you even noticed the technique I placed in your eyes. Don't worry. It's the same as before, just a safeguard. It activates if you're killed, bringing you back to life five seconds later with your body completely intact."
