Viable Learning Experience
Dango had a great time staying at Yoshi Okino's house. He learned so many new things!
Despite being a young boy, Dango easily defeated the man. He did so because he knew the man's... preference. He restrained him using materials and tools that he found inside the house.
He now had the perfect test subject!
Yes! Yoshi Okino became Dango's test subject which he planned on using to explore his capabilities and further his knowledge.
There were two main things Dango sought out to do; to understand more about his innate cursed technique and to learn more about the human body for medical ninjutsu.
Both topics were important, but the latter was slightly more important. He didn't know how to use reversed cursed energy to heal so he could only rely on ninja healing.
Dango practiced with his curse technique first just in case he might accidentally kill the test subject during a 'healing' experiment.
For Dungeon Formation, he wanted to know whether or not he could bring someone into it and the apparent limits to doing so. Although his previous experiences of traveling in and out of the dungeons with Hex showed that he could bring in a living creature, he needed to confirm if he could do the same with a human.
For his Personal Dungeons, Dango was able to bring someone in and out of it with ease. He understood what the requirements to do so were:
The target must make contact with his cursed energy during the dungeon formation process. It didn't even require a lot of cursed energy either, only a sliver was necessary. This meant Dango could just throw a stick that is imbued with his CE at someone and transport them into his realm.
He learned that if he left someone in his Personal Dungeon while it is being deconstructed, they would only get kicked out and relocated somewhere near him.
For the Cursed Dungeons, Yoshi Okino wasn't able to see the gate nor enter them. Dango didn't know whether or not his inability to sense cursed energy was the reason why (Yoshi Okino was able to see the interior appearance of Dango's personal dungeon despite having no talent). It could also be a special trait belonging to his technique that made it so that only he could enter Cursed Dungeons. He would need to see if a jujutsu sorcerer or anyone talented enough to sense CE could enter it.
When he was satisfied with his learning experience, Dango changed his focus to learning more about the human body and practice his medical ninjutsu. In consideration of Yoshi Okino possibly screaming during the experiment, Dango isolated himself, Hex, the test subjects, and even the wild cursed spirits inside his Personal Dungeon.
Ever since Dango was reborn, he felt a desire to learn everything growing inside of him. Initially, Dango was able to ignore it. However, now that Yoshi Okino was in front of him and the fact that Dango knew of the man's sins, that desire to learn skyrocketed.
Dango couldn't ignore it now. He fully embraced that desire.
Dango used Yoshi Okino as if he donated his body for scientific research. From making small cuts and healing them afterward to gently cutting his body open to observe the body structure.
Despite his actions, Dango was unfazed by them. He didn't feel any trauma towards the torture he was giving to Yoshi. All he felt was curiosity. Though, he did feel the minor disgust of being covered in blood.
Anyways, he spent plenty of time studying medical ninjutsu. Unfortunately, the related skill didn't advance due to him not concocting a poison yet.
On the bright side, Dango obtained a new skill. It was an unexpected, yet welcomed surprise.
=====
[Basic Torturing]
Description: Slightly boosts your proficiency at torturing. Minor mental trauma is inflicted when torturing someone with extremely unconventional items.
To advance the skill, successfully torture several individuals and obtain their secrets.
=====
Dango wasn't expecting there to be a [Basic Torturing] skill, though he should already expect it. He was even more surprised to get it just from performing multiple experiments.
It was a shame that the skill required multiple successful tortures to advance to [Intermediate Torturing]. But he should be able to advance it within the year he is in the 'modern' world. All he needed to do was to add it to the list of skills to train and advance.
As for the three cursed spirits that were originally attached to Yoshi Okino, Dango removed them. He placed them into separate containers and would occasionally feed them Yoshi's flesh. He was planning to experiment on them but refrained from doing so when the test subject died. It was a surprise that the man could last so long anyway.
The moment the man died, Dango received a mission completion notification. The mission was to obtain his first direct kill. He was rewarded with 10 CC, two times the reward he had gotten from the First Indirect Kill mission.
Now that the subject was dead, it was time to erase any clues of his existence and ultimately escape.
Using [Intermediate Searching], Dango identify and removed nearly all of the evidence that would have bitten him in the butt. He planned on carrying them until he found places to throw them out.
Of course, he didn't take larger items that would be impossible to carry such as furniture. He left them behind in hopes the police would get distracted by the evidence claiming Yoshi as a sinner.
Unfortunately, Hex left quite a bit of cursed energy residue. He tried but was unable to remove all of its residue. It would be a big problem if jujutsu sorcerers came to investigate. So, Dango released the three wild cursed spirits to try to cover up Hex's residue with theirs.
He placed Hex inside his backpack and left the house. After traveling for a couple of hours did the thought of burning the house down cross his mind. He lamented not thinking about it sooner.
During his runaway, Dango came across a strange sight.
A boy with white hair and beautiful blue eyes.
