The next morning, I came to the fourth basement floor of Nihonium.

　I checked the now board at the entrance to make sure I was in the right place, and the status was.

---1/2---

--------- ...

　Yesterday, the speed on the third basement floor was reduced to S. So from today, it's the fourth basement floor.
　The Nifonium Dungeon is like a so-called limestone cave, a dungeon worthy of being called a "cave".

　That doesn't change on the fourth basement floor, I wondered if it would change after the sixth floor, which requires a license, as I continued on.

'Oh, there it is: ...... is it Mummy again?'

　I was puzzled for a moment.
　The encountered was a muscular, humanoid demon wrapped in bandages.
　It looked almost identical to the mammy on the third basement floor, and I thought I'd gone down the wrong level.

You'll find out if it was a mistake or not--you'll find out when you take it down!

　The caves of this world, monsters are all about the drops.
　I was starting to realize that this was becoming common knowledge to me, so I thought I'd start by hitting the monster in front of me.

　I stepped in first, using my speed to get behind it right in front of it while keeping it close to me, and then I finished off the mummy's side.
　As the body bent into a "ku" shape and blown up, I quickly aimed at the head with a penetrating bullet.

　The bullet pierced his head, and Mamie staggered back, only the bandage remained in place as if the contents had melted away.

　.......
　.......
　.......

　I waited a moment, but there was no drop.
　The monster was gone, but the bandages were still there and the seeds that should be there didn't drop.

It's not the same as ...... third basement level.

　I mumbled something to myself.
　This had never happened before, the mummy on the third basement floor never disappeared, leaving only bandages behind.

　I left the bandage on the spot just in case and hunted for another Mammy.
　This time, I killed it instantly with the mummy's weakness, a fire fusion bullet.

　Then, after all, only the bandage remained.

''Hmm, what does this mean?''

　The lack of drops is a bit of a problem.
　My ability is Drop S. It's a better S than the world's best A. I've been using it to drop monsters that never drop, and they don't exist in this world.
　With that Drop S, I've been able to drop monsters that "never drop", and they don't exist in this world.

　If you beat them, they'll never drop, and that's what I consider a drop S.
　So the no-drop situation in front of me was troubling.

'Are there exceptions to the drop S?　Hmmm.

　As I was groaning, something strange happened.
　It was a monster whose contents had melted, leaving only bandages, but this time, like a video played in reverse, it felt like the contents had been filled in (...) and swelled up in a flash.
　The bandage returned to the bandage man and attacked him.

'Oops!　So that's it!

　Conviction, and relief.
　It's not that I didn't drop it, I just didn't defeat it.
　Then I'll just defeat it properly, so I'll fight the monster again!

　Remembering what happened in Seren, I loaded the gun with tracking rounds and fired.
　The tracking bullets are excellent because they are bullets that chase the enemy and hit 100% of the enemy, and not only that, but they also aim at the enemy's weak points on their own.

　I fired it in rapid succession - and lo and behold, all of the bullets didn't bend, didn't go to the weakest point, and were shot straight into the mummy.

　That made me stumble for a moment, and then Mummy fleshed me out and hugged me.
　Bearhug, or mackerel fold.
　The mummy hugged me with such force that it snapped my spine.

"Ko......'s oh!

　He gritted his back teeth and shook off Mummy's bearhug.
　He kicked off with a front kick and used the momentum to fly backwards and launch a flame fusion round.
　It was burned by the industrial flames, and only the contents melted away, leaving only the bandage in its place again.

　Now, here's the thing.
　This guy will revive, he hasn't been defeated yet.
　To prove it, I shot a tracking round directly behind it and it bent 180 degrees and slammed into the bandage.

　Which means we'll need to make some more strikes from here.
　I stepped on the bandage, pecked at it.
　It didn't fight back, so I picked it up and yanked on it.

　It looked like an ordinary bandage, but it was so strong, it didn't look like it was going to break.

"Nuh-uh-uh!

　I'm on the force, and it still won't come off.
　So you need a special technique.

　...... I know what it looks like.

　Special rounds are loaded, except for the tracking rounds you've already launched, and the bandages are placed on the ground.
　First he shoots his intended target, a flaming round, which didn't burn.
　Next, he throws in a freezer round, which only froze, but didn't do anything.

No way.

　Finally, I shot a recovery bullet into it.
　The light from the recovery bullets enveloped the bandage and it melted away in a flash.

　The one that couldn't be torn off when I pulled on it with my strength S melted and was completely gone in less than 5 seconds after being shot by the recovery bullets.
　And there, the seed was dropped.

　-- Strength increased by 1.

''Yes!''

　I was gutted.

　To fully figure it out, I look for the next mummy.
　I turned back the way I had come and found the revived mummy where I had just defeated it.

　I fired a recovery round - nothing happened.
　I fired a recovery fusion bullet, a sleep bullet - nothing happened either.

　In a meatball fight, I took it down with a rush of punches, melted its contents, then fired a recovery round at the bandage, and the bandage disappeared and the seed dropped.

　I got the gist of it.
　I'd have to kill this mummy once, leave the bandage alone, and then use my recovery powers to finish it off.
　Once I knew that, I prepared my recovery shot and got into full-blown mummy hunting mode.

　As long as I knew how to beat them, they were almost as strong as the mammies on the third basement floor.
　Looking for a pattern to work with, I raised my strength from F to E.

　　　　　☆

　Nihonium basement level.
　It's almost noon, time to meet up with Emily and the others.
　But first, I need to make sure we're okay.

　I'm going to grab my gun and look for a skeleton.
　Right now, the gun is loaded with the mummy in the fourth basement, the special bullets I got after I haggle it.

　The Nihonium dungeon is almost a "me only" dungeon.
　If you defeat it normally, you'll drop seeds that only I can raise my ability, and if you use the collection box to take them out of the dungeon, turn them into hagremonts and defeat them, you'll get a special bullet.

　I'm going to join Emily and the others after checking the effects of the bullets in the four underground floors I got for the first time.

　A skeleton immediately appeared.
　A move that my body completely remembers. I kept my distance from them, no matter what happened, and fired the special bullets.

　The bullets that were fired went poof!　The light shone and burst.
　A light of about 0.1 seconds in time, about the last burst of fireworks.

　After that light, the skeleton was unable to move.
　It was tied to the rope of light and was unable to move.

　...... I see.
　In addition, this is a "straitjacket", I guess.

　I need to find out how to use it, or at least the effect and the range of the bullets.
　I'm suddenly very excited to get a new tool.
