Hard work

5 years later

Lucifer has already mastered the Fishman Karate as well as martial arts style Rokushiki as well as armament haki. Lucifer also found old ruins of a city made out of marble, where super-strong apes live and fight against him. Some of the apes even have haki and have been able to surprise Lucifer quit a bit. But in the end, Lucifer fought them all at once and dominated them to the point that they saw him as there leader of some sort.

In the ruins, there is also a temple where not even the apes go

Lucifer is right before the temple and walks in with an improvised torch to illuminate the dark place. While Lucifer goes deeper into the temple he sees statues of sword fighters holding a real sword. In the temple were 7 statues and the one at the end had a demonic aura in it. It was like the sword was calling Lucifer. The Sword is an Estoc that has lots of fancy work on it. The Statue is a man with wings and a Nobel looking outfit.

Lucifer tried to get the sword from the statue but the statue was harder to brack than it looked. Then Lucifer got into his hybrid form and used haki to boost his power even more. At the moment the statue broke Lucifer could feel the sword building a connection with him. Lucifer wasn't sure what exactly happened but he took the sword and left the temple.

When Lucifer left the temple he was greeted by all the weird apes. When Lucifer stood in front of them they kneeled down in front of him. Even the leader of the apes came to him and kneeled. Lucifer wasn't sure of what got them to do this but he got the feeling it has to do something with the sword he took out with him. When he looked at the leader he felt a connection to him as well. Lucifer directly new what happened and tried to order the apes to leave by saying" Leave for now my underlying I want to talk to your former leader."

To Lucifers surprise the leader stayed and all the other apes got back to there homes. Lucifer then began to talk to the ape leader about what he wants them to do and how they are supposed to help him train. Sine the ape leader can't talk back he is just nicking his head all the time. Lucifer also gives the ape instructions on a little house they should build him.

Another 3 years pass

Lucifer now has mastered Fishman Karate, Art of the Sword and he mastered his devil fruit to perfection. His haki is also mastered as well as the advanced haki techniques. The Apes are also a lot stronger now. When they saw Lucifer train every day to the limit they go inspired to train and master his techniques. The former ape leader also got way stronger and trained an elite squad of apes.

All members of the elite squad mastered observation haki and armament haki as well as Martial arts style Rokushiki. They and their squad leader Rhaus all fought day in and day out against Lucifer to train him and them self.

As for the sword, Lucifer found he is sure it is at least O Wazamono grade sword or even a Saijo O Wazamono grade sword. He also has great control over it and it never has a cut something Lucifer didn't want it to cut. Since the blade itself doesn't seem demonic as bevor when he found it, it now seems to glow in a supreme light. For the other blades, Lucifer found in the temple he gave them to the elite squad which they saw as an extreme honor there were not worthy of and trained even more and harder. The swords are around Ryo Wazamono to O Wazamono.
