Nifonium, basement level 8.
　It's been a while since I've been here alone.

　When it comes to laps, I'll bring Leia with me, but I was able to do it myself the first time.
　If I'm on my own, I'm thinking that no matter what happens - I'll be able to do it.

　As soon as I entered the eighth floor, I encountered a monster.
　Again it was a zombie, but it wasn't just any zombie.

　The body was humanoid, but it was on all fours.
　The figure had no clothes, or even skin, and its pink muscles were bare.
　Even more deformed than that is its three extended necks.

　A hydra zombie in a human body.
　Such words popped into my brain.

''We'll have to do a quick check first.''

　Three of the necks are exactly the same, the same face on the level of triplets.
　I fired a conventional round into one of those necks.
　The bullet hit right between the eyes, a head shot.
　But it didn't work.
　The bullet lost momentum and hit the ground with a plop.

　Not that nothing happened.
　The zombie's torso was on all fours, its head disappeared in a haze, and then it was down to three heads again.

'That's something: ......'

　Muttering that, he shoots one more time - ugh!

　The moment the headshot hits, there's a thump in my brain.
　My eyes went blank, and I felt like my consciousness was going to fly away.

　As my upper body slumps and wobbles, the zombie quickly leaps at me.

　I jumped to my feet, rolled on the ground and ducked.
　As I got up on my hands and knees, I saw the zombie's head snap back into place for a second, then turn back into a three-headed monster.

　It was a quick decision, and based on my experience in battle, I knew what the three heads were...
　I checked the zombie's leg with a conventional bullet.

　The bullet momentarily blew off the leg, but it regenerated - the leg regenerated without even losing its balance.

　The other leg shoots out, regenerating just as quickly.
　The zombie that pounced on me didn't feel drained at all, and the momentum and pressure(,) of the attack was the same.

　You probably won't be able to take them down, no matter how much you try to do anything but their necks.
　The weak point is the neck, and it can be one of three things.

　And the breakdown of the three heads is predictable.

　Head shot to make sure.
　It hits me between the eyes, uneventfully, and the heads disappear and regenerate.
　Conveniently, on the fourth headshot, I finally shoot the head out and the zombie collapses in a heap, its body falling apart.

　As expected.
　Three heads, one invincible, one reflex, and one weakness.

　The invincibility is literally invincible, even if you attack it, it is nullified.
　Reflexes are probably doubled or tripled or so. The impact that came between his eyebrows was that much, and if his HP and strength weren't SS, he was in danger.
　And another neck, if you shoot through there, the zombie disappears.

　The problem is that if you attack any one of them - or rather the two that are outliers - the heads will disappear and shuffle once they're gone.

　It's a zombie that always has to make three choices, three dangerous choices.

　I pick up the dropped seeds.

　--One up on my luck.

　Ability increases steadily, but they're a nasty piece of work.
　The next zombie showed up in a hurry. I'm the only one who comes to this dungeon, and there's no rest for the wear.

　There's a repetition, but I sealed it up first.
　I have to seal it until I can capture it for sure.

　But what to do: ...... That's right, tracking bullets.
　It's a tracking device that drops from the trash hagglers, Frankenstein.
　It chases the enemy's weak points, a bullet that was also used in the Dungeon Master battle.

　With that in mind, I fired.
　The tracking bullet drew a homing trajectory and flew into one's neck.

''--Guhahaha!

　The moment it landed, the impact came to me again, enough to make my eyes go blank.
　The impact, this time delayed until I recovered, and I took a bite from the zombie's lunge.

　Quickly, I hit the head that had been bitten.
　Apparently it was an invincible neck, and when I hit it, the head disappeared and the bite was released.
　I kicked the ground and flew backwards wide.

　I hit myself with a recovery round.
　Phew ...... that was a close one.

　Why ...... when it's a tracking round aimed at a weak point?
　After a bit of thought, one theory emerged.

　I fired another tracking round, and at the same time I put the recovery round on standby.
　The moment the tracking round landed, I fired a recovery round at myself.

　The impact came again, and the trigger of the recovery round that I pulled down at the moment of impact made me move quickly, and I took evasive action.

　A tracking bullet, a bullet that aims at a weak point.
　The reason why the reflexes are doubled or tripled is because that neck may mean that its defense is weaker than other heads.
　That's why the tracking bullet aimed at that point and the counter came.

　In other words, the tracking rounds only aim at the neck of the reflex.

That's fine then.

　I grinned.

　Three times I load the tracking rounds, and this time I charge at the zombies, shooting in the direction of the day after tomorrow.
　I focus, assessing the trajectory of the bullets.
　In the world of speed SS, I know the neck that the tracking bullet is aiming at from the trajectory.
　At this moment, the area has gone from one-third to one-half.

　If the tracking rounds are definitely aiming at the reflection, then the other two that they are not aiming at have real weaknesses.
　And no matter which of those two you do, the reflection won't come.

　I moved even faster than the tracking rounds and shot a half of them.
　It seemed to be an invincible head.

　Once he got away, more tracking rounds, more rushes, another half - again invincible.
　Once more - still invincible.

'You're pulling a little too hard.

　I started to laugh.
　Well, I decided that it could mean that the selection of tracking rounds was working.

　The probability of running over a third in a row is 1 in 27, compared to 1 in 8 for a half in a row.
　A 12.5% chance is just one in eight.

　Fourth time's the charm, and this time I've blown a real weakness and got a seed.

　I continued to hunt the zombies with the tracking bullet selection.
　It took me eight challenges to take down five of them, and my luck is converging on one-half of them.

Even at .......

　I wondered if I could keep it up.
　A choice of two halves, a choice after crushing the reflection.
　That works as a strategy, but I want something more.

　To narrow down the choices further.

...... hello.

　I came up with a possibility. I decided to try to tame it.
　A test that would probably not matter if it failed and was reflected back.

　A zombie appeared, and I fired a barrage of recovery rounds.
　I fired a recovery round at each of the three necks.

　The bullets hit and released a recovery light.
　The zombie's head didn't reset!

　It was a bingo.
　The zombie's head resets when it's attacked, but the recovery doesn't.
　And then one of the three bullets didn't heal well, so the bullet hit the ground.

　Probably an invincible head. Because I felt my reflexes recover.

　I reviewed the head carving chart in my head and loaded the pistol with a tracking round and a recovery round, respectively.
　I take a deep breath and rush forward with my eyes wide open, as faster movement is required.

　I shoot a tracking round, and that trajectory makes my options a half.
　I rush in faster than that tracking round and shoot a recovery round at zero distance, I didn't recover.
　I blew the head off the one remaining head more by spinal reflex than by thought.
　The zombie fell and dropped a seed.

　You take the seed and raise its status even more.
　It was an even greater satisfaction than status.
　It was because I had established a strategy.

　Carve out reflexes with tracking bullets and carve out invincibility with recovery bullets.
　These two types of bullets and the speed SS are interwoven with each other.
　After successfully attacking the eighth floor of the Nifonium basement, I first raised my luck from F to E on this day.
