( During 6 months)

Naruto trained during this time. He pushed his body to his limits and practiced the six techniques of the marines to his full capacity. In the morning he practice this six techniques. After his lunch he trains his Haki. He tested all the theories of haki. He was natural in observation and conquerer's Haki but he pushed his body to his extreme limits for the armament haki.

He didn't forget to train his newly awakened Rennigan. He trains his chakra and magic after he practice his Haki. For last six months he didn't receive a call or stepped out of his savage island. But he sent his demons to take the body of the giant who fought against Marines in the marineford battle.

They easily found him and later he was turned into a giant death knight by the Naruto. He also got an information about the Marines wants to eliminate Moria by his shadow demons. So he sent some of his demons to take another gaint's dead in his custody which moria used against Luffy. And the gaint also turned into a gaint death knight.

Naruto is secretly building an undead army in his island. He not only ordered to take oars body from the marineford. Shanks and marines buried the dead body of pirates and marines in the sea. He ordered his demons to steal them except Ace and Whitebeard's body. And now the dead marines and pirates also joined the army of Naruto unknowingly.

He summoned a lot of undead, demons and beasts for his army. Basically he was trying to practice his summon magic. But it became a large army for him unknowingly.

And he appointed elder liches to teach his army about the secret techniques of this world. Even he doesn't know the exact number of his army.

(Present day)

Naruto is looking at the game panel after his practice. He saw his level reached 230 in this past 6 months. He used gacha free spin for a day and found 1 million yggdrassil gold coins.

'I am damn lucky today,' Naruto thought in his mind.

He checked his game panel and looked at his guild bar which only shows Ainz ooal gown guild is inactive. And many names are below it. Albedo, Demiurge, Cocytus, Aura, Mare, Shalltear, Victim, Pandora and the list of names goes on.

'If I had them it will be a different story. I have so many memories of Ainz in my brain. It is not like I can active the guild. I only got Ainz's power not his servants power,' Naruto thought and subconsciously clicked the inactive button in his game panel. But the button changed from inactive and become active.

[Guild activated]

[ Restoring guild]

[ Restoring Floor and floor guardians]

[ Restoring all the NPC's of great tomb of Nazarick]

Naruto is near his Fortress and at that time a bright light engulfed the area. And an underground tomb appeared near his fortress.

All the demons and undead who serve Naruto came immediately and surrounded the tomb to protect him. And the two Giants death knight also took their position.

'Now I have to explain it to them,' Naruto thought in his mind.

"There is no need to worry. I summoned this tomb. There are many other undead and demons inside it. So don't attack them , they work for me," Naruto said to them. He didn't think that he will summon the full force of Nazarick by himself.

Before Naruto can move towards the tomb. A demon and succubus came outside the tomb. Both of them looked around them and saw a large army is ready to pounce on them if they made a wrong move. But they are still not at the level of this two beings.

Both of them bowed in front of Naruto.

"Rise, Albedo and Demiurge. It's is my lucky day that I am able to summon you back among the living beings," Naruto said to them. And both of them got up after hearing his words.

"Lord Ainz, I am glad to be back on your service. But why are you in a human form?" Albedo asked the Naruto. She can feel he is their supreme being but why he is in a human form. But one thing is sure she can satisfy her lord's desire in his human form.

"I have been reborn in this world. I don't have the full memories of my past lives. But I have the power of my past lives with me. And now my name is Naruto Uzumaki instead of ainz ooal gown," Naruto said to her in a calm manner. He has memories of Ainz and Naruto in his mind. In a way he is now one with them.

"It looks like you have tried a lot to summon us and I can see a lot of undead beings, demons and beasts here. I am sorry for the inconvenience you have to go through,Lord Ai... Naruto," Demiurge said to the Naruto. He is delighted by the thought of Naruto was trying to summon them. Well they doesn't need to know that their arrival is a mere accident by Naruto.

"Voldy and Jeni come with me inside the tomb. Demiurge and Albedo call all the floor guardians inside the throne room except Gargantua," Naruto said to them. And both of them immediately messaged floor guardians about this immediate summon.

After that Demiurge, Albedo, Jeni and Voldy followed him inside.

From the first floor they teleported directly to the 9th floor. And Naruto saw maids and servants in the 9th floor. All of them bowing in front of Naruto.

Soon all of them reached inside the throne room. He saw the world item' throne of kings' and it looked so beautiful. He walked towards it and sat upon it. Soon the world item's power started to course through his body.

He saw all the pleiadas and Floor guardians arrived inside the throne room except Gargantua. Gargantua size is so large that he cannot fit inside the throne room.

"We pledge an absolute loyalty and obedience towards Lord Naruto," All the present members of tomb said it in one tone. All of them are kneeling in front of him in a knights style.

"You can rise. I have an important matter to discuss with all of you," Naruto said to them. And he looked at Jeni to come forward and speak with them.

Jeni started to explain about this world. She also explained Naruto's current standing and the powerful people around the world. And she gave them an accurate report of the new techniques which is necessary to learn by every summons of Naruto.

Demiurge looked fascinated by hearing about Haki. Albedo wants to learn it so she can impress Naruto. Shalltear also have the same plan. Cocytus wanted to face powerful warriors in this world. Aura and Mare wants to explore the world. Victim wants to remain inside the tomb after learning the techniques.

"Jeni, tell your sisters that they will come and from now on they have to live inside the tomb. And the elder liches whom I summoned earlier will live with the elder liches of this tomb in 3rd floor. And everyone will learn about secret techniques and Haki in our tomb. Even our homunculus maids will learn it. And I will stay inside the underground tomb from now on," Naruto said to them. He liked the architecture of the inside of this tomb and he would love to stay here.

"My lord, what we will do with the fortress near the tomb?" Voldy asked Naruto. He wants to know what he has to do with that fortress.

"Our army will use it. And I am thinking of making three fortress like the previous one around the tomb to keep it secure," Naruto said to them. After that he sent them to rely his message to everyone.

After the meeting is over between them. Naruto went to see the private room of Ainz ooal gown to take rest.

This world doesn't know about the arrival of dangerous beings who can change the shape of this world. They are only waiting for the orders of Naruto to create chaos.
