In his transformation as Ace, Tanaka reached the underground laboratory where Danzo was hiding. He knew he was in the right place because of the various grotesque experiments in the room. There were jars containing possible DNA samples from people.
Using the Invisibility Cloak Technique, he completely concealed the energy he was emitting and quickly exited the dungeon.
As he did so, the environment shifted, returning to the real world. There, he sensed the presence of six people. Their chakra wasn't strong, but outside the door of the underground laboratory, he felt two more presences. Now, they were at least at the level of Chunin.
From behind the invisible cloak, Tanaka's eyes darkened. This was because he saw four men in white lab coats surrounding a child no older than five years, who was gagged with tears in his eyes, while these men in white lab coats held scalpels and needles in their hands.
"It's done. Now we will test his compatibility with the cells," one of them said.
"Out of the ten children, nine died. This one must survive, or else, Lord Danzo will be upset with us..." another said, fearful.
On the other hand, another spoke coldly and nonchalantly: "Why would he be angry about these humble lives? In the end, we are the ones who will fulfill his dream, right?"
Suddenly, information flooded into Tanaka's mind. It was information from his clone that was infiltrating another location. A smile curled on his lips before being replaced by a cold expression.
From Tanaka's hands, strands of MP began to slither across the floor. First, he sent them through the crack in the door, and then they reached the feet of the men in white lab coats. As soon as they connected to them, Tanaka opened the dungeon.
When the men in white lab coats saw the environment change, they also heard the sound of the door opening and the two ninjas guarding the entrance entered.
"What just happened?" asked the ninja in a black overcoat and a peacock mask.
The ninja next to him, who wore a panda bear mask, looked around. He seemed to be the sensory type.
"No one... I don't sense anyone's presence but ours. It's as if we've been isolated by some barrier," he analyzed shortly after.
"Barrier? Have we been discovered?" asked the ninja with the peacock mask, naively.
"It seems so," replied the other ninja.
"D-Discovered?" Upon hearing this, the first to panic was the one who had treated the lives of the children who died during the experiments with indifference. He turned pale.
He knew very well what it meant to be discovered while conducting inhumane experiments.
"What should we do?" another said, panicking. "We need to warn Lord Danzo!"
"Silence!" The ninja with the panda mask grew irritated upon hearing Danzo's name mentioned so easily. He wondered who the genius was there, him or the others?
Support creative writers by reading their stories on Royal Road, not stolen versions.
The men in lab coats swallowed hard as they tried to remain silent.
"Show yourself, I know you're there!" shouted the ninja with the peacock mask.
Removing the Invisibility Cloak, Ace appeared.
"I know you hadn't discovered me, but I have no reason to hide anymore, if you catch my drift," Ace said, raising his left eyebrow.
══════
A few minutes earlier, Ace's clone had appeared at the Root Headquarters, in Danzo's well-guarded office, full of seals and formations. However, Danzo probably never imagined that someone could infiltrate through a kind of mirror dimension and, upon emerging, would be directly in his office, bypassing all the precautions he had taken, right?
There, the clone managed to gather enough information to incriminate Danzo. There were records of everything he had done over the years.
'Why did he keep these records? Was he so confident that no one would be able to infiltrate here?' the clone thought.
But that didn't matter. He took everything he could and placed it in a large box, transferring it to the inventory.
In moments, the room, once full of files, whether research documents or records of Danzo's actions over the years, was emptied, leaving behind only an empty room.
Having done this, the clone made a hand seal and disappeared, sending all the information he had collected to the original body.
══════
Meanwhile, in another laboratory, another clone of Ace revealed himself to the ninjas in black overcoats and white animal masks.
There, four men in white lab coats were conducting slightly different experiments. In their case, they were testing cells from the First Hokage while also having some Sharingans in jars.
"Who are you?" asked one of the ninjas who entered the room upon seeing him.
Making hand seals, instead of responding, he used the Temple of Nirvana Technique. Soon, feathers began to fall.
"Do you really think this will affect us?" mocked the masked ninja as he asked. To him, it didn't matter who the intruder was now; all that was left was to capture him and then torture him, making him confess everything.
"Who said this was meant to affect you?" Ace said, raising his left eyebrow.
Soon, four thuds were heard. It was the men in lab coats falling to the ground.
"Damn..." Realizing who the real target was, the two masked ninjas became worried.
This was something that should not have been discovered.
However, before they could act, Ace appeared in front of them in a flash, with his hands surrounded by flames.
"Goodbye," he said.
"Boom!"
══════
Back at the original body, Ace simply pointed his hand at the two ninjas, and they began to catch fire. He achieved this through Psychokinesis. It was possible to use an ability by indirectly touching with Psychokinetic energy, just as it was possible to produce fire. Of course, it was weaker than if it were used directly, but it served the purpose.
"Ahhhhhh!"
Their screams echoed as they tried to extinguish the flames with their hands, panicking, but that was only the beginning. Soon, Ace appeared before them and pierced them with his flame-wrapped hands, striking their chests.
"He... he killed them!"
The faces of the men in lab coats turned as white as their garments.
Ace turned toward them, causing them to retreat, but unlike what they believed, Ace didn't kill them. Instead, he made hand seals, and soon white feathers began to fall from the sky, causing them to faint.
With everything done, Ace tied them up in two groups of three and gagged their mouths.
After doing this, he opened the inventory. Seeing the signal he needed there, he knew that on the other side, his clone had also finished and destroyed the dungeon.
Taking a sample of the First Hokage's cells, he also collected some files and began to leave, setting explosives to create a hole in the ceiling. When it seemed that the same had been done by his clone, he opened the zombie dungeon once again.
Then, he started to flee, taking the men in white lab coats with him, while the ninjas he had killed were stored in the inventory.
══════
That night in Konoha, a large explosion occurred in two different locations.
This woke those who had already gone to bed and alerted those who were still awake.
Soon, the site of the explosion was exposed.
"What is this place?" asked a Konoha ninja who was nearby, reaching a remote area surrounded by trees.
There was a hole in the ground, and just below it, a kind of clandestine laboratory.
More and more ninjas began to surround the area, and the same was happening at the other explosion site.
Danzo, upon learning of it, arrived at one of the locations and turned pale as a sheet.
'W-Who did this?' was the first question that came to his mind. The second was: 'Have I been discovered?'
══════
Meanwhile, in the Uchiha Clan, a "package" was delivered to the clan leader's doorstep.
It consisted of four bound and gagged men in lab coats, along with a note and a box full of files.
In the Senju Clan, the same thing happened. Even Mito Uzumaki was unable to detect who was responsible; when she tried, he had already disappeared, leaving behind three men in white lab coats and a box full of files.
Finally, in the Hyuga Clan. Although there wasn't much about them, there was still some information regarding the clan, as well as research on their Byakugan. Three men in white lab coats and a box were also left at the clan leader's doorstep.
══════
As Konoha turned into a sleepless night, the one responsible for all this returned to his rented room and slept peacefully.
No matter what happened next, he had done his part.
If, even after all this, Danzo somehow managed to turn the tables... He could only blame Konoha for being too naive.
