This Knight Has Been Enhanced to an Epic Level

I traveled through time and became a knight, awakening the [Epic Enhancement] system. The system said: Host, you have been enhanced by the epic level! I said: OK! Strengthen what? Fencing? Holy light? Dragon Knight? The system said: No. What is strengthened is - your fist. I fell silent. System: Host, why are you silent? Me: I was wondering how a knight would survive in this world without a sword. System: You can punch the future with your fists. Me: I want to log out of the system. System: Once this system is bound, it cannot be returned or exchanged. I wish you can use your fists to create a wonderful life of your own in this world. Me: Can you at least give me a fucking shield? ! System: [Shield Mastery has been permanently locked. By the way, any weapon the host uses will suffer backlash. You're welcome. I:? Thus, a knight without a shield was born!
