He remained standing even after receiving such a big attack. My chakra reserve is not empty yet so I continued to make more hand seals.
But this time I decided it was going to be the last technique before he died. While I was making hand seals he came towards me quickly.
Before I could finish my hand seals he had already hit me. I didn't have time to finish so I was forced to use Taijutsu.
His speed and strength became enormous with the forbidden technique he had just used. Since I am not physically strong enough I was forced to use one of the Taijutsu techniques I had just created.
I made 10 hand seals quickly, and a green light appeared around me. This is one of the techniques I created before the battle.
With this technique that increases my speed and strength enormously, I took advantage of the Uchiha clan elder.
We continued the battle using Taijutsu for 10 minutes before I finally killed him.
The elder I just killed was the most powerful person on the battlefield. That means we now have a huge advantage over the Uchiha clan.
I've recovered the eyes of the Uchiha Clan Elder. I didn't take his body, I only took his eyes to implant them later.
