I Survived the Catastrophe and Awakened the Waste Collection System?

I am the Second Pillar, and I was originally a top student at the Advanced Swordsmanship Academy of the Kingdom of Terra. But unfortunately, just now, I was plotted into an evil competition. Erzhuzi only told the truth and did not tell lies. In fact, I didn't want to compete with him at all. He forced me to compete with him. I was not prepared before the competition. My iron brothers were too busy and no one helped me to threaten the audience and stop the competition. My mana characteristics are different from others. I consumed too much mana in the last match and the last match. Someone must have tampered with my sword. My equipment has not been maintained for a long time. I wore the wrong shoes because I wore someone else's. The shoes make my movement not very flexible. I haven't had a good rest these days. I have never been specialized in swordsmanship. In fact, I am a student majoring in the Archmage major. I am not a swordsman. This competition location is very strange. The abnormality caused my mana to run out of balance. This sword is definitely not mine and it broke so easily. These people must be extras, and they would not be so brave normally. They must still not obey me. This competition is illegal... I, Li Erzhu... Can't beat him at all... Erzhu never imagined that he would be deeply hurt by a junior fellow who had no morals in martial arts. He would be kicked away by a young boy with two swords, and his body with nineteen holes would fall off the cliff while wailing. "I'm going to die, I'm going to die, I'm going to die—I'm not going to win!!" "Eh? Am I still alive? Eh--"
