At least 1150 years have passed, and 9 months have passed in real life. This means my injuries are nothing to scoff about as it's taking this long for me to gain consciousness and wake up, and undoubtedly my skills have grown a lot over the thousand years I've spent training.
[The skill 'Perfected Sword' has evolved!]
[The skill 'Primordial Sword' has been achieved!]
[You've gained another achievement!]
[You gained a skill unique only to you!]
The meaning of primordial mixed with this sword skill means that my martial arts have achieved the same state as the first sword arts in the entire world, and in the world of martial arts and in magic somehow the more ancient the martial arts or spell the more powerful they are as it was essentially used by masters who first invented them during a time where mana and qi ran abundant.
