I think I put in that kick more strength than I had to, I didn't adapt to my new strength after my last training after all, I approached Seraf then said "Can you let me examine you? I am a medical shinobi too!" He looked at me surprised for an instant then said "Ok" I put my hands on his abdomen and concentrated my chakra sens on that area for about ten seconds then said "It's an old injury that reopened when I kicked him!" The two were surprised at my statement then I began my treatment. Healing hand was good at external injuries but with chakra sens I could heal even internal injuries and after half an hour I finishing my treatment. We stood up then I said to him "You're not injured anymore but you have to rest at least for a week to completely heal!" He thanked me and walked out of the training ground, I stood there with the clan head then he brock the silence "Seraf is one of the strongest and experienced shinobis in the clan, beating him means you're qualified to be my opponent" He looked at me, and I felt like it was a beast that was looking at me not a human, it was the first time in my life feeling this type of pressure, the man overwhelmed me with just a glance.
