He meditated again, and spread his chakra field throughout the room, \'Hmm, nothing here.\' His chakra field then expanded into the walls, floor, and ceiling of the room.

And he noticed, \'What\'s this? It looks like there\'s a stone with a high amount of wind chakra in it. And it\'s very dense. It looks like while meditating here, we absorb chakra from it in small amounts. That\'s why I got that weird feeling.\'

Fujin got off the mat and made a hand seal. \'Earth Military Movement jutsu\'

He entered the floor. On entering the floor, he could see a lot of seals, and inside the seal was a green crystal. Fujin analyzed, \'Probably not a good idea to test these seals. But the crystal has very dense wind chakra. And it looks like it can help make our Wind element stronger. Is this chakra metal? Or something else like an ore? Well, let\'s call it the Wind Chakra crystal for now.

The important question is, can I absorb it faster? And, how can I get more of them? Also, I need to check whether all other elemental training rooms have something similar.\'

He went above the floor and thought, \'I should have dinner for now. After dinner, I\'ll check if I can absorb this energy rapidly. I wonder what benefits I\'ll get from this. Though I should also be careful in case it\'s harmful to absorb it in excess.\'

He left for dinner. He met Hoka and Mieko there. They had a small chat. The chunins in the tower also introduced themselves and had small talks with the genins. After dinner, Fujin returned to the Wind Training room.

He began meditating and tried absorbing as much energy as he could from the Wind Chakra crystal. While meditating, his entire focus was on the Wind Chakra Crystal and its energy.

In the first 6 hours, he didn\'t have much success. However, sometime after that, he began steadily absorbing energy from the crystal. He lost himself in meditation, completely losing the sense of time! When he opened his eyes, it was already 7 AM!

Fujin analyzed, \'I didn\'t have much success initially. But I think I managed to use up 1% of the energy of the crystal in this meditation session. I wonder if this absorption rate is fast or slow. And how often does Konoha switch or recharge this crystal?

That aside, unlike what I previously thought, I don\'t absorb energy from the crystal directly. Rather, it refines my chakra. I have a feeling that I\'ll have a slightly easier time performing Wind jutsus.\'

He frowned, \'Though improvement would likely be very minimal. I\'ll need to use up more energy from this wind chakra crystal to get a proper idea. I have a feeling that I might need a mountain of such crystals to get a significant boost.

That aside, it feels really good to train here. I ended up meditating all night and skipping my sleep, but I don\'t feel very tired at all! Though I should take a nap tonight. Meditation, though good, can\'t entirely replace sleep.\'

After analyzing, he got up and left the room. While leaving the floor, he came across Tsume. She was surprised to see Fujin on the 2nd floor. Her eyes twitched and she asked, "Were you training the whole night?"

Fujin laughed awkwardly and rubbed the back of his head, "No. I was meditating in the Wind training room. And I ended up falling asleep there."

Tsume\'s eyes twitched even more. She sighed and said, "It\'s good to train hard, but don\'t forget to rest. Or else, the training can be counterproductive."

Fujin immediately replied, "Yes ma\'am" while thinking, \'That\'s the first time I haven\'t heard her yell\'

He left, got freshened up, had a huge breakfast, and returned to the Wind training room.

After knowing that Fujin returned to the Wind Training room, Tsume realized, \'He is an orphan. He has probably never experienced such rooms. No wonder he is training in that room. I should report this to the 3rd. He\'ll be happy to know how hard some kids are training.\'

He spends the next couple of days in the Wind Training room. Though he went out regularly for food and sleep.

As he meditated more in that room, he managed to use up the energy at a faster rate. By the end of the 3rd day, he had used up 18% energy from the crystal. He analyzed, \'Good, it is getting faster. I have a feeling that it\'ll be even faster tomorrow. But, it seems like my analysis was right. While this definitely is good, I\'ll need a mountain of such crystals to actually get significant boosts. I wonder how many crystals Konoha has. And where they are kept. Another point to consider is how much energy from this crystal was already exhausted before I began training here.\'

On day 4, as he predicted, his efficiency suddenly increased a lot. In around 12 hours, he ended up using up almost half the energy from the crystal. However, on this day, he noticed 1 crucial point!

Fujin realized, \'My chakra increased? Yeah, I can feel it. Though the increase is very minimal, not even 0.1%, it did go up. Damn, now I really want to find a mountain of such crystals! Where are these found?\'

He calmed himself down and decided, \'Lucky, this crystal\'s efficiency hasn\'t reduced. I guess this is due to the seals. But I should stop here. I might be able to completely exhaust this crystal before this round ends. But if my speed of using this energy is higher than normal, then I\'ll get a lot of unneeded energy. I should check out the other rooms and see if they have similar crystals, and if I can refine my chakra with their energy as well.\'

After dinner, he went to the Earth Training room. On entering, he used \'Earth Military Movement jutsu\' and went underground to check. \'As I thought. A similar crystal with dense Earth chakra is here. But, the amount of chakra seems low. It has only about 15% of the chakra as compared to what the wind chakra crystal had.\'

He thought for a bit and concluded, \'Makes sense I guess. There are barely any ninjas with the Wind element in Konoha. While quite a few have the Earth element. So this room ended up being used a lot more.\'

He sat on the mat and spent his entire night meditating in that room. He opened his eyes at 6:30 AM and sighed, \'I thought since I managed to increase the speed of consuming the energy of Wind chakra crystal, I\'d be able to do the same for the rest. Unfortunately, that isn\'t the case. I have to start from the beginning.

Worst of all, my rate of consuming energy from Earth chakra crystal is very low! I think it is just around 5-6% of what it was when I started with Wind chakra crystal. Does this mean that the speed will depend on my affinity towards each element? It went fast for Wind chakra crystal because my affinity is wind. But for Earth chakra crystal, my affinity is very low.\'

He analyzed a bit, \'Wait, does this mean that I can analyze my affinity to other elements depending on how quickly I can use up the energy of each crystal? Yeah, that should be the case. I should check out the other 3 rooms.\'

After having breakfast, Fujin went to the Fire training room. Here he followed all the procedures as usual. However, when he checked the Fire chakra crystal, he was shocked! \'The Fire chakra crystal has 25% more energy than the Wind chakra crystal. How? Shouldn\'t Konoha be full of ninjas with Fire affinity? Could it be that the previous Fire chakra crystal got used up and they replaced it with a new one?\'

After thinking for a bit, he nodded, \'Yeah, that should be the case.\' He began meditating. He got up before lunch and analyzed, \'Oh, my Fire affinity seems to be decent. At least it\'s much better than Earth. The absorption speed here is at 35% compared to what I could do at the start with Wind chakra crystal.\'

After lunch, he went to the Water Training room. He first checked the amount of energy in the water crystal. It was around 30% of what the Wind chakra crystal had. Fujin sat in meditation and meditated till 4 PM.

At 4 PM, he got up and sweated a bit, \'I couldn\'t refine shit! I didn\'t manage to use up any energy at all!\'

He sighed, \'Does this mean that I have no talent in the Water element at all? A shame. I was hoping to have a good affinity for the water element and to take over Tobirama\'s jutsus.\'

After taking a small break for eating, he went to the Lighting Training room thinking, \'My main affinity is wind. So I don\'t really have much hope for the Lightning element. Oh well, let\'s test it out.\'

[A/N : I\'ll give the exact details regarding Elemental Crystals a few chapters later. I don\'t think these were available in canon (though not sure if movies had something like this). So all this is made up for this fic.]
