Douluo Continent: The Drunken Sword Immortal slaps Ning Rongrong in the face right from the start!

Ye Yan transmigrated to the world of Douluo Continent, where his martial soul awakened a jet-black nameless sword and a wine gourd, along with a system that made him "get stronger by drinking".
At Ning Rongrong's birthday party, he was falsely accused by Ning Rongrong of hitting her and was questioned by Chen Xin, Ning Fengzhi and others.
How do you explain things that weren't done?
Then let's fight in front of everyone!
Ning Rongrong gets slapped right at the start!
Am I drunk?
"Everyone else is drunk but I am sober; it's just that you all can't see the world clearly."
"A carefree immortal in this world, I am the immortal of wine!"
"With wine and a sword, I roam the world, laughing and carefree!"
