Luffy ALREADY destroyed half of marineford and punched Garp out of his way
![Milaugh :milaugh: :milaugh:](https://i.ibb.co/ypRqMmV/Mihawk-Laught.png)
And the funniest part, forget about Garp letting Luffy go... I'll be logical and not ignore the fact he let him go...
The funny part is... a VERY TIRED exhausted Luffy with TONS of wounds, who has been fighting SINCE Impel down with NO REST.... And a very serious FRESH Sengoku who used his DF + his attack was AIMED to execute BOTH Ace and Luffy according to Sengoku's dialog... and Luffy took the attack HEAD ON... and was FIIIIINNNNNE
I don't need to tell you if Luffy CAN DO what Shiki did in Marineford... becuase Luffy was actually SIMILAR in a lot of ways to begin with in Marineford hahaha
This is so funny... you asked a question that was ALREADY answered in Marineford arc
For your second question, I honestly read it THREE TIMES and still don't understand it... rephrase it again or explain what you mean because I didn't get it
