(UNKNOWN ISLAND, EAST BLUE)
(MC POV)
After I made up my mind to train myself before heading out in the world I left the lab to explore the rest of the bunker. Leaving the lab I reached a long hallway with a few doors labelled as storage, sleeping bunker, bathroom, training room etc. Exploring the bunker I realised something devastating.
"Shit!They don't have any food or water here. They must have put all of it in the scrolls to keep them from getting stale. So unless I learn how to mould chakra fast I will have to go hungry for God knows how many days." After the revelation I quickly grabbed some clothes from the storage discarding the towel and ran towards the training room.
Entering the training room I realised that it was a lot bigger than it seemed. There were some weights for training the body and wooden logs to practice shuriken throwing among other equipment. I sat in the middle of the ground in lotus position to meditate and go through the information in my brain on how to mould chakra.
'Hmm... according to the information Chakra is essential to even the most basic technique; it is the moulding of the physical energy present in the body and the spiritual energy gained from exercise and experience. Once moulded, it can be channelled through the chakra circulatory system, which is to chakra as the regular circulatory system is to blood, to any of the 361 chakra points (called tenketsu) in the body. Through various methods, the most common of which is hand seals, the chakra can then be manipulated to create an effect that would not be possible otherwise, such as walking on water, exhaling fire or creating illusions.
By moulding different ratios of the two energies, new types of chakra can be formed. Most ninja have a natural affinity to one type of chakra, but they have the capacity to create elemental chakra apart from their own affinity. There are five basic types, each stronger and weaker to another, but their relations, weaknesses, and strengths to each other are all explored. There is also the dealing of Yin and Yang and the balance of mental and physical energies. In addition to these five elements, certain kekkei genkai can mix elemental chakra to form new natures, for example it is possible to mix water and earth to create wood. While many ninja can use more than one type of chakra, very few are able to use them to create new element.
With this new knowledge i started mixing my physical and spiritual energy together after half an hour I was able to feel some changes in my body. There was a new energy situated beneath my navel I tried to circulate it through my chakra coils with extreme difficulty. After a hour of extreme pain and concentration I was able to complete one circulation following which I blacked out and slumped down on the floor.
(4 Hours Later)
I woke up having an intense headache and feeling weak all over my body. I got up shaking and walked towards the sleeping bunker walking staggering. I got myself into the bunker arduously and threw myself into the bed.
'Damn! I must have blacked out due to chakra drain. I should concentrate on increasing my chakra for now my chakra is barely comparable to a student's. My chakra control is also shit I should start doing the leaf exercise as well. But before doing any of that gotta rest my body first.' (A\N His first time moulding chakra gave him academy genin level chakra due to his Uzumaki bloodline)
Waking up after a few hours I moved towards the exit of the bunker to get myself some leaves to practice chakra control. "Damn it's so bright out here. I should quickly gather some leaves and get out of here don't want to stay here for too long." I pick up some leaves which were scattered everywhere due to me being in a forest when suddenly I hear a roar punching me into 5th gear as I bolt towards the door.
From the corner of my eyes I was able to make out the silhouette of a giant tiger. I dive into the bunker closing the door behind me before the tiger could catch up.
'Damn I still too weak just the roar of the tiger was enough to scare me. I gotta up my training since I have 4 bloodline I will work on one for every 6 months. Let's start with Uzumaki since it doesn't need high level of chakra. I will train myself to be a sensor ninja and also learn fuinjutsu i should be able to learn it pretty easily considering Uzumaki were fuinjutsu master. I will leave the bunker after 6 months to hunt for food should give some combat practice.' With my new resolve I started my 2yrs of hellish training.
