Naw..... And since I'm learning.....
Mistake #1: You did not combine the 2 Jutsu into a "stronger" S-rank, you perform them as separate techniques.
Detail Evidence #1: Furthermore, your S-rank fire would have only been able to heat my earth-armor, causing the earth particles to expand, resulting in fractures spreading at the front of the armor.
Detail Evidence #2: However, I strengthen the technique, turning it into a "stronger" S-rank, having resistance.
Mistake #2: Your S-rank technique shoots multiple fireballs, which divide your technique and decrease its ranks based on the amount of fireballs created (yet equaling the rank).
Detail Evidence #3: You shoot 8 fireballs, which is equivalent to B-ranks. ([B+B+B+B+B+B+B+B] = [S-rank])
Detail Evidence #4: My earthen-armor is a "stronger" S-rank, capable of blocking and withstanding against B-rank attacks.
Now to your counter.
Although, you completely ignored utilizing the Fire Release: Fireball Shower Technique and falsely assuming you destroyed my "strong" S-rank earthen-armor, your second technique: Earth Release: Stone Spikes, have no effect. I might have been caught in the tremors, but I would be safe from your spikes because of my armor. However, it only validates if I carry it over to the next turn, I believe, or it could be mistakes on your part, which should change the scenario of the battle. Anyway, I was going to cancel the earth technique and use RasenShuriken afterwards.
....But I'm not going to continue this match. I'll rematch you some other time, without the talking; and let's make it official.
