No matter the place, the orphanage can be easily found in the outskirts. Now the reason is simple, it is cheaper and can be expanded easily later.

I walked out early morning 6 into the adjacent forest, the talk from yesterday seems to get Rimo-san to allow me this. Otherwise, I would have already heard her shouting to me to stay in the premises. This led for me to believe she is a sensor and the reason she is assigned the orphanage; a sensor is the second-best thing to torture unit in anti-spy capability.

I sat myself against a tree and sat in the lotus position. I started to take deep breathes and focused the morning chirping of birds and flowing water sounds from the adjacent river.

Begin simulation

[Host chakra is being simulated.]

It felt like an adrenaline rush from the stomach, spreading from there to my heart, from there to rest of the body.

It was incredible my body feels alive like I had a buffet after a day of fasting and boosted by Coffee.

I kept focusing on that sensation until AI began prompting,

[Scanning,

Host ATP are being fused with unknown energy in cells and forming Chakra.]

Term it as Spiritual energy.

[Task completed.

Spiritual energy is being released from the soul and fusing with the ATP (physical energy) in cells. Chakra is following the circulatory system throughout body.]

AI stop the artificial simulation.

[Simulation stopped]

I still felt it. I still feel my chakra flowing through my body rotating along the blood and lymph (tissue fluid).

It's unbelievable, I can feel my muscles, heart beating, my stomach, blood bumping to every part, even the contractions of the intestine. Chakra is like a fusion between the muscles and nerves. It can receive and send information along with movement.

Hmm, Receive and send information.

AI, check whether information of my body can be perceived through Chakra.

[Task received.

Checking. Found the task possible.]

Do it.

[Scanning the body, processing the information.

Showing the data in perceivable form.]

"Haha, Unbelievable."

I saw prompts with ECG data, Vitals, brain waves-EEG and even Muscle sprains. My chakra is completing the task that took machines worth Millions of dollars in my previous life. No wonder, Tsunade can progress the medical field to such level. She is like a Specialist in all fields with a super speciality hospital in medieval world.

[Warning, Chakra is being consumed as the information is being sent.]

[Glucose reserves are dropping; glycogen reserves are consumed, and Calories are burnt.

ATP levels consumption can't be met.

Stopping receiving the information.]

Then an intense exhaustion hit me as if I spent an entire day running while reading mind numbing medical text.

Chakra exhaustion, though mild one. If AI didn't stop the task, the chakra usage will pull the vital ATP required for normal functioning of body causing Shock, coma and even death is a possibility.

Shinobi naturally train themselves to stop from reaching these limits. Of course, otherwise is also possible in emergencies. Same as Kakashi did in the canon.

It was after a heavy breakfast; I came back into the forest.

AI show me the current profile.

[Name: Yuta Yamashiro

Age: 3 year

Knowledge: Post graduate general medicine, High school level education.

Chakra: 5 units]

As soon as I moulded the chakra again, I felt that increased. It seems my cells adapted to sending out more ATP to fuse with Spiritual energy.

There is not much need for me worry about Spiritual energy due to my mental maturity and experiences.

But it's the body I need to train. Then again, I can make myself a regime based on my body for maximum efficiency. Thank god for my AI chip.

AI implant into me Chakra training exercise- Leaf.

[Consuming 1 unit of Chakra.

Implant completed]

I then found memory of attaching a leaf to forehead, hand and even feet.

I soon started the exercise by placing the leaf on my forehead, my chakra followed my prompt to move- From Stomach to heart and from there to head.

But it is not consistent with the memory. It's like pulling an unwilling child to school.

AI scan me for inconsistence.

[Scanning.

Chakra consumed for exercise one unit.

All functions are normal.

Abnormality found: The body is not familiar with the process. It needs repeated attempts to adapt to it.]

Ok. No wonder there. Shinobi clans took generations to change their bloodlines to have easy extracting of physical energy AKA ATP and send Chakra throughout the body.

Even civilian born shinobi train till they achieve both mental and physical adaption aka cakra control. Unlike them, I have a completed mental adaption. Like Uchiha where they can observe and the chakra and process the jutsu with a glance. The scary part is they even have physical adaption too. No wonder, they were driven to extinction without the senju to hold them back. Others need years to master them, but they can do it in glance.

Sigh.

I just need to practice for mastery. AI calculate the attempts to master this exercise.

[Calculating ….

Leaf exercise attempts- 1/1000]

This is with me cheating with AI. No wonder the exercise follows throughout the shinobi school.

AI show Hypothesis 4

[Chakra is a mixture of Spiritual energy and Physical energy.

Jutsu are made from Chakra shaping and Nature transformation.

Now Chakra Shape formation is apex of chakra control.

Nature transformation are the elements- Wind, Fire, Lightning, Earth and Water.

Now each transformation is influenced by variety of factors, but the main ones are the bloodline and nature of chakra.

Bloodline is more likely termed for clans like fire release in Uchiha and Sarutobi. Water and Earth in Senju.

Chakra nature being the way the chakra flows, if it vibrated then Lightning. It's the reason a seasoned sensor can distinguish the chakra nature on sensing.

It's the reason the chakra nature can be trained but the problem is changing the way it acts to other. For example, it's like commanding our hands to vibrate every second while doing work.]

AI check my nature.

[Processing the chakra information recorded.

Nature found to be- Fire.]

Fire.

Hmm, check the feasibility from Hypothesis 6-fire

[Hypothesis 6- Fire.

It's the literal burning of ATP as fuel.]

[Feasibility confirmed.]

Simulate the transformation and implant it to me.

[Beginning task,

Time remaining: 3 hours]

I got up and started running. Putting my body through its pace seems to be a good idea while doing waiting.

AI record the process.

I soon forced my chakra to come out from my hand and willed it to burn. A small fire spark came into existence before I collapsed on to the ground with a burning felling throughout my hand. WTF

[Record completed.

Findings: 5 units consumed.

Minor degree burns throughout hand.

Expected time to heal a week.]

No wonder, chakra transformation is started in chunins, anyone below has too low of reserves and weak body to handle the aftereffects.

Sigh

AI estimate the minimum reserves for holdable training in chakra transformation.

[Compiling data and cross referencing.

Units required: 1000 units.]
