Naruto: Reincarnation With All Existence System

Before Ren left the demon bat clan he decided that he would sneakily get some more demon bat blood because he wanted to try comparing it to normal bats. Since Ren didn't know if the elder demon bat had someone watching him, he chose to have All Existence tell him if anyone was watching him. All Existence told Ren that currently, three demon bats were secretly watching him and also told Ren where they were currently, and this cost 500 points. When Ren learned the location of the demon bats watching him, he noticed that they weren't close to each other and so he couldn't just quickly turn them all into vampire servants. The method Ren ended up deciding was to continually sense the location of the demon bats and then once they all let down their guards he was going to move at his fastest speed and turn them into vampire servants.

After around two hours of just pretending to look in the library, Ren noticed that all the demon bats didn't have their guards up. So he activated his owl chakra aura to make himself completely silent and then he began to use blood boiling to make himself faster. Then once Ren was prepared he completely disappeared from all the demon bat's sight, so they began to try and use echolocation, but right before the sound waves could come back to them Ren knocked all of them out. After they were all knocked out Ren took many vials of their blood and then turned them into a vampire. Now that they were a vampire Ren had the vampire and demon bat bloodline mix together and took many vials of their blood now.

Once they were all vampire servants Ren gave them the same commands as his other vampire servants, and also decided that he would have them completely destroy their blood before their death because Ren read that demon bats would drink other demon bat's blood after death to absorb some of their strength. The next thing Ren did was go to the elder demon bat and tell him that he decided to go leave the demon bat lair to get battle experience.

"Elder, I am going to leave the lair for a short while to gain experience with the demon bat techniques." - Ren

"You can leave the lair, but I must have some demon bats come with you so that you don't tell others about our techniques." - Elder demon bat

After the elder demon bat said this he had Ren wait a few minutes for some other demon bats to come here. Once the demon bats who were going to watch Ren came, Ren recognized all the demon bats as the ones who were spying on him before and were now his vampire servants. Now that the demon bats who were going to watch Ren, Ren left the lair with them. Since Ren had turned all the demon bats who were meant to be watching into vampire servants, he had them tell all the information about the location of the other demon eagle clan. The reason why Ren wanted to go to the demon eagle clan first was that he wanted to get their eyes because it would help him do experiments.

The vampire servant demon bats told him that they didn't know much about the location of the demon eagle clan, but they told him that a demon eagle was last spotted near the most northern part of the land of demons. Since this was the only lead that Ren had he decided to just go up north and then try to find some demon eagles. Now Ren began to run north, and after running for a little while he decided to go on top of one of the demon bats and have them fly north. After a little less than one day, Ren was now at the most northern part of the land of demons. So used transformation jutsu to make the demon bats look like demon eagles then had them search around for demon eagles.

Now that the demon bats were searching for the demon eagle clan, Ren decided to have all his vampire servants in the land of fire except Soruki (AN: OC currently learning in the temple of fire) go out and find the land of sky. The reason Ren wanted them to find the land of sky was that he wanted to get some of the zero tail's blood to compare it to demon blood. Now that Ren had everyone doing something he decided to buy a weak jutsu that used the lunar element from All Existence. When Ren tried to buy a weak lunar jutsu he saw around tons options come up. Since Ren only wanted a few jutsu he decided to narrow his search by having only lunar jutsu related to ice jutsu. When Ren did this three options still showed up.

『Showing weak lunar jutsu related to ice jutsu

- ice senbon jutsu: Creates a moon near Host that will condense and freeze water vapor into the form of a senbon. Cost: 500 points

- ice fog jutsu: Creates a moon near Host that will make a fog that is made of small ice crystals. Cost: 750 points

- ice explosion jutsu: Creates a moon near Host that will condense water vapor then freeze it, once frozen the ice will explode. Cost: 1,000 points』

Ren decided that he was going to buy the ice fog jutsu and the ice senbon jutsu because he thought that with the ice senbon jutsu he would learn how to make solid ice objects and then with ice fog jutsu he would learn how to make small bits of ice. Now that Ren bought those jutsus he decided that he would buy some weak jutsu that were purely lunar release instead of being based on water or ice release.

『Showing weak purely lunar release jutsu

- Mooneye jutsu: Makes a moon that can function as a third eye for the Host. Cost: 1,000

- Moonlight refraction jutsu: Makes a moon that can refract the light around Host to mess up someone's vision. Cost: 1,000』

Since Ren still had 48,680 points he decided to buy both jutsu. Now that Ren had all the jutsus that he wanted right now he decided to it was time to learn those jutsu and then he could begin testing to make his own jutsu.
