No Otaku with Harem System

The closer we got to the hospital the more infected we found, the mutants began to appear.

Mikoto suggested taking a secret path that led to the underground rear area of ​​the hospital through a tunnel.

I had to put aside my new hobby of running over people and we circled the area to get to the secret path. The area was clear since it was an uninhabited area so they had not infected, only some mutant animals.

Although it would be useful to take them to increase the strength of our team I did not have time to tame them as it would take from a few hours to a full day to subject them to my Intimidation ability while they are immobilized so they do not escape.

I used my Intimidation ability so that the mutant animals did not approach, we quickly reached the secret tunnel and went through it, it was a complex system of tunnels where it would be easy to get lost if the correct way was not known in addition to having multiple traps, if Mikoto did not come it would take me weeks to find my way.

When we reached the exit of the tunnel that connected with the secret entrance to the underground area of ​​the hospital we found that the place was blocked by several rocks, a collapse must have occurred, but the problem is that there have been no earthquakes so a strong explosion must have occurred.

I got out of the car and looked at the rocks, I have worked in construction so I learned various things about architecture and demolition. To remove the rocks you would need heavy machinery, the other option is to destroy the rocks, but they are too big and heavy.

"Will we have to go back?" - Mikoto looked anxious.

When we were on the way to the hospital we heard some explosions so they must be in a difficult battle.

I will have to use my new trick, it is just a prototype of a new technique that I am developing so it is not perfect and it puts a lot of stress on my body as well as requiring preparation time so it is not effective in combat yet.

"Mikoto back away" - I went to the rocks.

Mikoto was anxious, but she did what I told her, she's cute when she's obedient.

I spread my legs, raised my left arm vertically parallel to my torso in a defense position, my right arm went back to prepare a direct karate strike.

This was the pose from the Dance of Four Gods moves series, the first pose: Basaltic Fist, but a custom version.

First, get my heart to increase blood flow by targeting blood flow to my right arm.

[Skill: Advance (100%), Activated]

Then it is to make the Ki cover my blood vessels to prevent them from being damaged while the Hamon optimizes the muscle tissue to make the muscle fibers not tear when hitting.

Then it's Madness's turn.

By doing a couple of unpleasant experiments, I discovered that black blood can harden inside or outside of my body. When outside it can become small weapons like needles, threads, or razor blades, but it is extremely difficult to control and I need the help of Madness.

When the black blood is in my body and it solidifies it does not obstruct my blood vessels and instead improves the strength of my body, my organs and it is even harder than steel, the problem is that using black blood for a long time causes me to pain headlong, dizzy and ironically, a state of madness.

In fact, my Berserk ability activates automatically if I use black blood for more than 5 minutes.

I currently have 300 milliliters of black blood in my body due to the Madness surge, it may not seem like much, but it is enough to harden my fist and enhance my attack.

Black blood flowed to my fist, although there is no change in appearance the hardness of my fist with black blood and Ki is equivalent to the reinforced steel of an armored truck.

This was not all, the air around my fist began to spiral as the Rasen altered the flow of my Ki so that it spun like a drill.

A mechanical sound similar to an excavator began to play, the sound getting louder the more Rasen put on my fist.

I cannot use all my Rasen and Ki in this technique or my fist would explode, I am currently using my new technique at 40% of its power which will make my arm go numb for 5 minutes, if I exceed that limit I will not be able to use my arm for a few hours or even days.

While the sound of a drill was so loud it hurt my ears, I prepared to hit, Navi suggested a name for this technique and I liked how it sounded.

The fact that yelling the name of the technique or skill when attacking improves combat power seems ridiculous to me, but I can't change it.

"Giga ... Drill ... BREAK!" - My voice sounded like a bestial roar as the drill sound complemented the destructive sound.

* giant drill sounds *

* sounds of things exploding *

The main rock blocking the entrance was pulverized, the surrounding rocks were thrown away as they exploded.

I was careful calculating where to hit so that the rocks did not hit the cars when they exploded, the place was filled with dust and debris, but no one was injured.

I looked at my hand, the skin on my knuckles was injured, but instead of bleeding, there was only a metallic black color inside the wounds. Black blood helps prevent bleeding so Madness is not as useless as Navi.

I used a bit of Hamon to start the wounds to heal, I have already determined the amount of Hamon I can use without attracting infected. I can't do a full treatment or use the techniques to adhere to slippery surfaces, but treating small wounds is not a problem.

"Good, now let's go" - I called my group who only looked at me with stupid expressions, only Saeko was calm as if this was normal.

"... You have to teach me to do that" - Mikoto looked at the rubble in amazement, even if I have already explained my strength, is different from hearing him to seeing it.

"It's not perfect yet, when I finish designing my martial art I will teach all of you" - I kissed Mikoto's forehead, I like it when people seek to improve either in strength, technique, or knowledge.

"Can it be adapted to a sword technique?" - Saeko approached with curiosity.

"I plan to adapt my techniques to the use of any weapon, my idea is that even bullets can use this technique" - Masters in shooting techniques also exist.

Kenichi's father was a Master level expert in shooting techniques, but his lack of physical power and the fact that he does not possess Ki makes him a crystal cannon, a strong attack, but nonexistent resistance. That is why it was easy for me to use acupuncture to alter his nervous system so that he could not touch Saori.

When this is over I will return to Kenichi's world, I want to see Kenichi's face when he knows that I will be his stepfather and future brother-in-law.

"Can I learn it?" - Arashi approached with curiosity.

The subject is the third person who tries the most to learn the martial arts that I have given them, in terms of dedication he is only below the girl Naoki who is too stubborn for her age, and Saeko who has shown dedication that is close to obsession.

So far Saeko is the only one who has managed to awaken the Ki, although she still cannot use it the fact that she can feel it in less than a week of training makes her a terrifying genius.

As a reward I gave her the Growth Type Sword, it is an ancient-looking katana that grows stronger with its user so it is a weapon that starts out weak but has unlimited potential in the right hands.

I decided not to use that weapon since, although it could grow by my side, my specialty is many weapons and I do not want to focus on a single weapon, that sword has the restriction that it can only have one wielder and the user who uses it has to make a contract where you will not be able to wield any other sharp type weapon, you are not even allowed to use simple scissors or nail clippers.

Despite the inconveniences, Saeko was more than happy to receive it, the best thing is that she did not question the origin of the weapon as her loyalty rose to 100%.

Needless to say, I was very fond of Saeko that night.

Anyway, it's time for her to claim the treasure called Black Label. I generally hate surprises, but it would be a pleasant surprise if the Black Label women are in danger so that I can save them and start making a good impression.

While I hate the hero saving princess tactic, I can't deny that it's too convenient.

The secret entrance was a reinforced door with a fingerprint scanner, retina scanner, and a number pad for a password.

Mikoto was able to open all three locks, although her friends told her not to come back it seems they didn't have time to change the passwords.

When we entered we did not find anything strange, the place was large and could become an excellent base so I started to think that we could move here, but that depends on how bad the situation is upstairs.

Mikoto took us to a lifting platform that doubles as a heavy lift.

The higher we climbed the more I frowned, I began to hear sounds of gunshots, grunts, and screams, I used the Ki radar and sensed dozens of human presences that were being overwhelmed by hundreds of infected. My head ached from over information so I stopped the radar, but the situation didn't look good.

"The situation is dangerous, when we arrive Hirano will give support fire, do not explore far and only clean the nearby area, focus on mutants since there are more than 10 mutants lurking" - I looked at the fat man who was not wearing glasses now.

"Yes sir!" - Hirano responded like a soldier, he was armed with an assault rifle and a backpack with dozens of cartridges.

After talking I did eye surgery to repair Hirano's optic nerves so he no longer needs glasses and his aim became really terrifying.

To prevent Hirano from freezing in fear when fighting an uninfected human I had him kill some idiots who tried to assault me ​​when I was looking for supplies.

It was a small gang of survivors who thought they might rob me because I was scouting alone, I captured more than a dozen and brought them to the base to use as whetstones for some members of my group, my methods were questioned by some of my kindest lovers like Shizuka and Megumi but Mikoto and Saeko supported my idea saying that it was the best way to build a temper, although when those idiots threatened to **** my lovers and kill me even Shizuka approved of the training.

Hirano vomited on his first kill, but after the fifth corpse, he could bear it, although I think his personality became more sadistic when fighting, as long as he remains obedient I don't care.

"Saeko and Rei will protect Alice and Yuki as they command the animals to explore the area, don't make the animals fight and just focus on tracking down mutants and survivors within 100 meters, report anything you find to Saeko even if it's just a shadow in the distance "- Saeko is the most trustworthy person I have in this world so I want her to learn to lead.

"Hai Onii-chan!" - The pair of girls nodded without fear of the danger they were about to experience.

Due to Rin's actions, the girls in the group idolize me to the point of obsession. I gave Rin advice to use people's weaknesses to her advantage, Rin took advantage of the fact that the girls felt lonely without their parents, and now all the family dependency was transferred to me so I am now like her father figure, the problem is that they are developing the Electra complex so they are getting bolder with their advancements.

Alice is an obedient and honest girl who will do anything to get approval, she was even willing to order her dog to bite the neck of one of the gang members.

Yuki is cute, but she is crazy, not crazy like Rin or Izumi, she literally has a delusional schizophrenia problem that comes up whenever she is under a lot of stress.

Despite her instability, Yuki is a capable child as somehow her mind interprets murder as a way of playing games so she happily orders the animals to kill her targets without the slightest regret.

Madness and Navi like the girl.

"Arashi, accompany Mikoto and take care of cleaning the entrance and looking for the hospital staff, remember, the priority is to survive, do not sacrifice for the civilians" - I have endeavored to implant the survivor mentality in my group.

"I will eliminate the mutants, if you see a dangerous enemy or begin to feel pressured by the numbers, go back immediately, do not take unnecessary risks" - I spoke seriously as the platform reached the entrance.

Although most of the people who do miscellaneous work still maintain their empathy for others, the battle group is already able to see for their own lives before the lives of innocent people, no stupid martyred heroes in my group, I have even acted as if the pressure of the environment is affecting my mentality so no one questions my attitude or criticizes me as someone cruel.

When the door was opening I thought of something.

Why didn't the hospital staff evacuate the civilians to the underground floor?

I used the Ki radar again and found the answer.

"Back off" - I made a sign for them to move away as I crouched down to prepare an onslaught.

My hand was covered in Ki and Rasen to launch a smaller scale Giga Drill Break to prevent my hand from going numb.

When we opened the door we saw him, he was a fucking man over 2 meters tall, his skin was a gray-blue color and he was dressed in a black raincoat, boots, and hat.

All around him were crushed corpses of patients, doctors, and nurses who were brutally murdered.

"GIGA DRILL BREAK!" - Before the mutant could react my fist hit his chest.

It was like hitting a steel pillar, but my strength was enough to drive him through the wall and out of the room.

I got up to hit again. - "Quick, move to help, there are not many mutants nearby, but stay alert, if necessary return to the platform and flee"

My group left the room while I was preparing for a second strike, the damn monster was getting up smoothly, this damn world is troublesome.
