Dazen had a surprised expression that soon turned into joy as he thought, 'This... The amount of chakra is much greater than I remember, it's at least 2 times greater, how is that possible?'

Dazen thought for a while and soon came to a conclusion: 'The Chakra is divided into two parts, the yang Chakra which represents the physical part and the yin chakra which represents mental strength, It seems that due to the fusion of the two souls my spiritual strength increased a lot which led to this absurd increase in chakra and not only that I can feel that the increase must be even greater, but perhaps because I am still physically weak the potential has not been completely released .'

Chakra needs both yin and yang parts to be formed, for now Dazen's physique is not as strong as his mind, so the amount of chakra that Dazen has is not close to his limit.

Dazen continued thinking: 'At first I thought that sage mode wasn't possible for me at all, as I didn't have the amount of chakra needed to learn it, but now it's maybe possible and even if I still can't learn, having more chakra is always good.'

Having reached this conclusion, Dazen began leaf concentration training. This training consisted of concentrating all your chakra in one point so that the leaf did not fall from your forehead. At first Dazen didn't have much of a problem, but as the minutes passed it became increasingly difficult to continue focusing all of his body's chakra on one point.

After 35 minutes Dazen made a mistake and the sheet fell, seeing the sheet on the bed Dazen thought: '35 minutes this was much higher than expected, I thought I could barely get 10, I think this is due to the fusion of souls, after all my mind is that of an adult, my control and concentration will be greater than that of a child, this is great and will save me a lot of training time.'

Dazen picked up the fallen leaf and continued with his training, he did this a few more times until he felt tired and went to sleep. The next morning, Dazen got up very early to begin his training, he took a ration bar that the village distributes to the orphans and ate it while running to a somewhat isolated part of Konoha.

Konoha had several training fields on the outskirts of the village, for ninja training they weren't the best fields, but they could be used by anyone and were generally empty, which was perfect for Dazen who wanted to train in secret.

Arriving at the training field, Dazen looked around, there wasn't much, just some targets to train with shurikens and a pole to train taijutsu, but for now that was all he needed.

Dazen started stretching as he thought, 'I'll start with some simple exercises to test my limits like push-ups and sit-ups and see how many I can do and then I'll run around the field to finish. There shouldn't be any problems with this type of training.'

Having finished stretching Dazen started the exercises he managed to do 50 push-ups, 100 sit-ups and 40 squats, having done this he took a 15 minute break to start running he ran several laps around the field which was around 8 km .

Having finished running, Dazen was on the ground exhausted thinking: 'Chakra really makes a lot of difference and to think that a 7 year old child can do all this would be absurd in my previous world, but in this world it is something completely normal.'

Dazen got up and went towards a tree to rest and in the meantime he grabbed another food bar to eat while thinking: 'This doesn't taste good, but it is very practical as it has all the nutrients the body needs, for now I will have to get used to this type of meal daily.'

After a good rest Dazen returned to practice, this time he trained the 3 basic jutsus of the academy until the end of the afternoon when he decided to return home. During this training he didn't make much progress in the 3 jutsus, but that was to be expected given how difficult it was to master them.

At home Dazen rested a little before continuing with his training, this time with the leaf concentration exercise, he continued with the training for 2 hours until he felt tired and went to sleep.

Dazen continued with this training routine until there was only 1 day left before the vacation ended and the ninja academy returned to classes, something Dazen was excited about, as he could meet some familiar people at the academy.
