I returned to granny's inn and took several days of rest since I just finished the test and was too tired from it. Seven days of constant vigilance drop my mental strength to almost zero. Lazying for few days made me recover and started planning on what to do best while waiting for the mission assigned. I remembered about the ores that I put in the pocket universe and asked system.
'System can I asked you if you can replicate the ores I just stored?' (Shin)
*Yes it is possible.*
'Then can I asked you to duplicate the two ores that I have stored. And also can you make me a new katana using those ores.' (Shin)
*Yes host. Please wait a few hours for the katana.*
'Thanks.' (Shin)
Doing my daily routine I remembered something and asked system about it.
'System can you create things like Cap's Serum or T-Virus to further strengthen my body? ' (Shin)
*It is possible to create those things but it well take at least twenty years of trial and error as system doesn't know the formula.*
(AN: Super Soldier Serum and T-Virus is harder to create than techniques like Ripple and Flying Heaven Govern Sword-style since techniques derived from information are easier to create than serums without specific formulas)
'I see. Then forget about the serum.' (Shin)
Thinking about my weakness as Flying Heaven Govern Sword-style focuses on speed and attack than defense makes me a glass cannon. Scurrying my memories of a technique that might help.
'I remembered "One Piece Six Powers" which was mostly used by almost everyone on "One Piece". If I remember correctly Iron Mass which hardens my muscles that it can even block or broke swords if mastered. Maybe I can even used Armament Haki here if I can master Iron Mass. Not only Iron Mass but if system can recreate Six Powers then I can have a greater chance on killing that bastard (Doma).' (Shin)
*It's possible to recreate Marine Six Powers and will take a few weeks as some adjustments are needed. *
'Then please recreate Marine Six Powers. Specially Iron Mass, Shave, Moonwalk, Paper Drawing, and Life Return. This techniques will increase my chance of killing that bastard (Doma) and Muzan.' (Shin)
*System now will start recreation.*

A few hours had passed and now I was holding a katana with only silver blade without ripple. The blade didn't change color when I hold. Doing a few swings to rest the katana I was very satisfied with the work of system. I tried using Ripple energy to the blade which was surprisingly smooth. The ores seemed high conductive of Ripple energy which is a good thing. Then I went out hunting demon to try my new blade like a child who got a new toy. My katana was so sharp and durable (thanks to system) which increased my hunting speed. Killing a few demons until o was satisfied, I returned home. As I rest inside, my Kasugai Crow which I named Itachi came with a mission. You know that bad a** ninja that likes crows.
"Mission! Mission! Mission! Investigate the rumors about a certain mountain where a lot of people went missing. Eliminate the cause if discovered. Head towards Mount Natagumo." (Itachi)
"Mount Natagumo it's kinda familiar.... Where did I learn that name? Hmmm... " (Shin)
*Reminder to host that Mount Natagumo is where one of the Twelve Demon Moon member lives. Specifically the Lower Rank Fifth.*
"Damn I almost forgot. It's where that not friendly neighborhood Spiderman (Father Spider) and it's family lives. Thanks for the reminder system. System can you remind me all the information I have about Doma and where to find that bastard." (Shin)
As I sort every information that system provided, I prepared everything I need went to granny and ask about investigating some things then headed out to Mount Natagumo.
