When I wrote the meeting between Sin and Doflamingo's men, I was tired and lazy to write anymore, so I let them keep their lives.
But thinking about it, it really dosn't make sense to just let them go, sooooo... I used the godly power of the Time time fruit, to change things.

-Update
Sin dodged the bullet and hit Gladius square in the face, and at the same time, he stuck a playing card on his chest.
*Crack!*
Gladius's goggles broke.
*Woosh!* *Bam!* Gladius flew and crashed into a building.
The civilians panicked and scattered away.
"G-Gladius!" yelled Buffalo before taking the Den den mushi and running.
He then grabbed the unconscious Gladius and flew away.
"Horohorohorohoro, do you think we will just let you leave like that, you idiots?!" said Perona before creating a few ghosts.
The ghosts pursued Buffalo when suddenly...
*Boom!* the card on Gladius's chest exploded.
*Woosh* Buffalo lost consciousness and fell to the sea along with Gladius.
*Splash*
Perona was surprised.
"Fight smarter not harder" said Sin, as he patted Perona's head like a wise elder.

"Are you mad?!" Capone "Gang" Bege of the worst generation, was sweating heavily.
Sin didn't respond to Capone's outrage, he just smiled.
"Do you have any idea of what Yonkos represent in the new world!" said Capone coldly, but inside he was measuring the pros and cons for this alliance.
"Are you afraid?" said Sin with a mocking smile.
"You!... Fine I will help you assassinate Big Mom" Capone gritted his teeth at the provocation, but he couldn't hide his excitement. A bloodthirsty smile appeared on his face.

Sin and Capone exchanged their snail's radio signal before separating.
After that, everything happened according to the cannon, the straw hats arrived, Zoro was about to kill a celestial dragon, etc...
"Young master!" yelled Ash, as he handed a newspaper to Sin.
'It's finally going to happen... The war!' Sin was excited, he wanted the Darkstar pirates to be known by all, but what other than "The War of the Best" could boost their reputation in this part of the sea.
Sin had no intention of saving save Ace or Whitebeard, what he wants is glory, excitement and paying the marine back for sending admirals after him, a rookie.

Sin and the other Darkstars were currently inside Doflamingo's Human auction housewatching an enraged Luffy walking to a Celestial dragon.
"What's that guy doing...?!" exclaimed a random person.
"Is he serious...?!" said Captain Kid.
"Don't get me started on you...!!" said Saint Charlos angrily.
Luffy suddenly punched him.
"NGUUUAAAHHH!" Saint Charlos Squealed Like a Pig, before he sent flying.
*Baam!*
*plop* Luffy's first was dripping blood.
The weak were shell shocked, while the strong were unfazed.
Law and Kid were even smirking.
"SORRY YOU GUYS..." said Luffy while scratching the back of his head.
"I HEARD IF YOU HIT ONE OF THESE GUYS... A MARIBE ADMIRAL GONNA SHOW UP WITH BATTLESHIPS" said Luffy, apologetically.
"Why did you have to go punch him?" said Zoro.
"I want to slice him up myself!" he said before sheathing his sword. *Clank*
"CHARLOS!!!" "CHARLOS-NISAMAAA!!!" yelled saint charlos's father and sister.
"Shit is about to hit the fan," said Sin, he could stop the smile from forming on his face.
"I hope they bring Kizaru!" said Ash, he was eager for a re-match.
"Reckless," said Bill with *Sigh* he didn't like how straw hats do things.
"These celestial dragons are disgusting, can I kill them?" asked Kuina or rather the Huntress, as she unsheathed her two swords Kuro and Shiro.
"Just leave them to the straw hats" Sin didn't mind killing them, but he didn't want to ruin his plans, because for the world government, Catching the killer of a Celestial dragon is more urgent than the execution of Ace.
"Shit! CAMIE-CHAN!" yelled Sanji.
"Now, then, Fish!!! time to die!" said the female Celestial dragon, while pointing her gun at the mermaid. (Author: a slave that Luffy and co, wanted to rescue)
*Thud!*
The female celestial dragon suddenly collapsed.
"See what've told you, Giant-kun... this place is in total chaos!" said an old man
"The auction is over, and I've stolen my money, guess it's time to head back for more gambling." he said.
