It wasn't Armament Haki, right? I think it was Flying Slash and Cutting Iron Realm

Nice idea

Remember, Vegapunk stated that there was no rubber fruit written in Devil Fruit Encyclopedia.

Nope! Think about it for a moment. Zoro had monstrous endurance from the beginning and he displayed it throughout the story. Sanji had a Germa bloodline. Not to mention, Sanji had gone through so much perseverance in his childhood. But Liam is different. He has grown a lot but endurance and Willpower still isn't something that grows over night. You will find it out later in the story just how much of a coward Liam was at the beginning and just how much different his starting point was.

Exactly, I have mentioned this. It might be in this chapter or the previous chapter or chapter after this. But, I have indeed mentioned it.

Uh-huh! I understand you that's why I said he only knows what I know. Because unless I want to change something about Luffy, he would still be Luffy that we know, right?

Hopefully no!

He does have Luffy's memories since almost everything that we know about Luffy had been revealed in the Manga and Anime. He also knows that he is from Earth but he just doesn't know who exactly he was.

That's Luffy for you!

But when you truly think about it. Luffy did manage to learn Advance Observation and Conqueror Haki in just a few hours.
