Nifonium, basement level.
　I walked around randomly, knocking down skeletons and going around.

　I'm using new bullets - I've named them growth bullets for now.

　The reason it's the first basement floor of Nifonium is because Seren told me that the more you hit it, the more it grows.

　Anyway, the best place to hit it, or just hit it regardless of the drop, is here at Nifonium.

　In other dungeons, there's no way you can do the "numbers" because you have to combine them with other adventurers.
　For that reason, I'd be almost entirely on my own in Nifonium.

　Darn!

　He pulled the trigger and shot through the skeleton with a single shot.

''Hmm, the power and speed are less than normal bullets. I'd say it's about 70%.

　A new skeleton appeared.
　He held two pistols at the ready and fired a regular and a growth round at the same time.

　The bullets shot through the skeleton's left and right shoulders, respectively.
　The growth bullets were clearly slower and less powerful than the growth bullets.

　That's not a problem.
　They're growth bullets, and this kind of thing is supposed to get stronger as it grows.
　The weaker they are at first, the more fun it is to see what happens after they grow up.

　I went around shooting skeletons, not caring at all about their weakness at the moment.

　I found them, defeated them with growth bullets, and dropped the seeds into the pouch.
　I repeated that anyway - but.

'This is going to be tough,'

　I couldn't help but say it out loud.
　Even with the number of seeds accumulated in my pouch, enough to raise my status by one rank, the level of the growth bullets did not go up.
　The letters that Selenium carved for me didn't go up, indicating level 1.

　I wondered if I needed to do something special, but I found out after a while that wasn't the case.

　I continued to shoot more, and after killing enough skeletons to raise their abilities by two ranks, the growth bullets quickly turned into level 2 as if nothing had happened.

　It would go up as long as I shot it, Seren was right.
　However, that would require a pretty hard number of times.

''What's wrong with that? ......

　Looking at the growth bullets that had reached level 2, I decided to rethink things.

　　　　　Stars.

　Seren Dungeon, the room of the spirit Seren.

　He used the transporter room from the mansion and came here with Leia.

''Yo.''
Wow, it's really happening again.
I told you I'd be back.
'I told you, I really didn't think I'd be back. I thought it would be a hundred years from now at the earliest.
In a hundred years, you'll be dead as a human being. What do you say we come here every day?
It gets old.

　Seren smiled good-naturedly.
　She's beautiful and s*xy, but her personality is quite bold.

　She looked like a gravure idol and a big sister with a personality.
　Selenium was a woman (spirit) like that.

So, what's yours?
Yeah, that's my guy. Her name is Leia.
It's the Master's.
'What's the play!　I'm so jealous!
No, it's not a play or anything: ......

　What's the weirdest thing you've ever imagined?

'Do me a favor, though. Can you put my no MP consumption on Leia?
That?
Yeah. I need it.
Ummm, that's impossible.

　Seren told me once and for all, and I raised my eyebrows.
　I thought I could ask for help because I'm a man who knows what he's talking about, but I'm not so sure.

"Do you have to?
That's for you. I can't just take it off and give it to someone else.
Well: ......

　If the MP was Leia, I'd have had a chance to do it (、、、、), but I guess I missed my guess.

'Don't miss,'
What?
If you're going to wear it on that boy, all right.
I see.

　This time he laughed bitterly.
　He wasn't misguided in thinking he could get away with it if he asked.

'Can you ask?'
Okay. But you know what you'll be asking me to do: ......
Yeah, I know.

　I approached Seren and put my hands on his shoulders, trying to get his face close to mine - that's when.
　Seren dodged my hand with a flick and went towards Leia behind me.

'Huh?'

　Seren ducked me and grabbed Leia's hand.

'Why?'
Isn't it obvious that he's the one to ask?
...... That's right.
So, can I leave you two alone for a while?
Um, .......

　I look at Leia.
　Leia nods quietly, as if to say it's okay.

　I used the transporter gate to get back to the mansion.
　After waiting for a while in the mansion, they returned to Seren's room.

　The two of them are delicately distant, and for some reason, Seren was glossy.

''Phew ...... egeta egeta.''
No, no, no, no, no. ...... What kind of a character are you?
I'm an old man at heart when it comes to dealing with pretty girls!
'Don't be brave!　I mean, are you sure you're okay with this, Leia?
Yes, sir.

　In contrast to Seren, who seemed to be subtly storytelling, Leia was as nonchalant as usual.

''I see, then it's good--''
'Because no matter what they do to you, your body and mind will still belong to the Master.
What have they really done to you?

　Me screaming.

'Don't worry, I didn't do much. And I don't want you to hate me for overdoing it.
It's kind of complicated. ......

　Do you believe that argument ...... for now?

'Yes, that's it. She's got no MP consumption in this dungeon, too.

　It was a bit of a shake up, but it got the job done.

　　　　　Stars.

　Seren Dungeon, first basement level.
　I came to the back of the dungeon, in an unpopular part of the dungeon, with Leia attached.
　What I'm about to do now could be seen separately, but I decided to do it here, since it would interfere with the adventurers who were producing properly.

　There was a monster, a slime with a rainbow-colored body.
　I shot it with a growth bullet and made it drop a soybean.

　I raked up the soybeans.

"Leia, it's Revive.
I understand.

　When Leia applied Revive to the soybean in front of her, the soybean turned back into rainbow-colored slime again.
　Instantly, the growth bullet killed it instantly.
　The revived slime returned to the soybeans again in an instant.

''Again, Leia.
"Revive

　Apply Revive, and Growth Bullets kill it instantly, then apply more Revive, and Growth Bullets kill it instantly.

　Leia's MP is infinite, and the number of growth bullets is also infinite.
　Shoot, revive, shoot, revive.
　The loop repeated.

"Master.
What's going on?
"I'll do it, Master, please rest.

　As he repeated absent-mindedly, Leia extended his arm and held the gun up for him to see.

'I'm glad you feel that way, but not so much. The only reason this is a loop is because the drop S will absolutely drop. Leia will run out of drops.
I see. You're a master.

　We continued to grow our growth bullets.
　It took a while, but the level was raised to 3 and the permanent engine was completed and working without problems.
