Play Tennis with the Script of Ancient Tennis Kings

My name is Irie World and I am a badminton player. Because I was bound to the ancient system, I was forced to play tennis. Although I haven't read King of Net fanfics, I have read other ancient novels, which are probably Marriage First, Love Later, Running with the Ball, Rebirth, Revenge and Cruelty... System: This is not old enough. Your mission is to defeat everyone and become No. 1. I:? Am I not the heroine? System: Yes, you want to disguise yourself as a man and become the main candidate. Even though I refused wildly, the system still sent me into the script without any explanation. Main mission: Become NO.1. [Current progress: -100%] Me:? How can this be a negative? All in all, after various situations, I successfully joined the Lihai Tennis Club. I thought I would be able to complete the main mission in my lifetime, but I underestimated the strength of the current No. 1 Player. Me: It's impossible for me to complete the main mission in my life! System: You only need to complete the ancient script to improve your tennis talent! I:? Is it really okay to complete the ancient script in the normal world? Note: 1. Write something about me, the king of the ancient Internet 2. The heroine is career-minded and dedicated to upgrading 3. The timeline begins with the main arc of Net King, and the heroine and Ryoma are both in the first grade. 4. [Highlight] Hanlong Ying CP Mission: Be brave enough to challenge the impossible!
