The clean looking pond was infact made from the secretion of the slimes. The water or fluid inside the pond was not gentle. Instead, it was acidic, burning the surface level, skin, with ease.
….
The shinobi attire on Reko began to dissolve as if made out of thin paper. However, his superior physique did not let his skin to be damaged.
Soon after, Tsunade and Shizune also jumped into the pure looking but acidic water. This was the moment when the practitioner of the technique needed most help.
Though the water was acidic, it also helped soothe chakra which was burning away because of the fruit they had taken. The constant burn and soothe allowed the chakra to reach a purer form.
Tsunade headed first to Sakura, the little disciple of her had minute chakra compared to Reko. So, she decided to guide her first.
"Follow my movements. Do not try to contain or save the burning chakra."
As she said this, her palms were gently resting on Sakura's abdomen, guiding the chakra.
Sakura barely nodded with her eyes closed. She trusted Tsunade and decided to give up on trying to control the chakra burning away from her body. She followed the unique chakra kneading technique by Tsunade, getting the gist of it in a few seconds.
'Good! She is doing fine now.'
"Shizune, assist her. I need to help him now."
Tsunade beckoned for Shizune to come and take her place. Even though Sakura was doing fine on her own, Shizune ready to assist would be a decent option.
As the water was slightly acidic, it was no big problem for a shinobi of their level to resist. The problem was the fruit Sakura and Reko had taken.
As their chakra burned uncontrollably, it became difficult to control chakra outside of their body, lowering their control over their own chakra.
Shizune glanced at Reko, his shinobi attire had already been dissolved by the water and so was everyone else.
Tsunade got close to Reko. Generally, she was aware of how big the chakra reserves Reko had. But at the moment, she realised that it was still above her estimates by a large margin.
She was not aware that her estimates were actually correct. It was just that Reko had a very unorthodox method of growing his chakra reserves. With the good amount of time he had spent with Tsume and Kurenai, it was obvious that his chakra would further increase.
Even if she assisted Sakura fully and then came to guide Reko, he would still have not lost more than twenty percent of his large reserves.
And his reserves were not the only big thing!
As Tsunade moved closer to place her hands on his abdomen. She could see something pointing at her. Something the same girth as her wrist,
Their clothes had burnt away and they were naked.
'But why is he so damn hard at this moment?'
As Tsunade thought, she tilted her head up and looked at Reko's face. His eyes were wandering around her body. Though, he closed them soon after.
'I cannot get close to that thing. I have to do it from here.'
Trying not to make it awkward for them, she slightly moved to block the view from Shizune and Sakura.
While doing so, she began to guide Reko. She tried to slowly guide Reko into moving his chakra according to the technique.
Reko followed, but his chakra still continued to burn away like crazy. The intensity was so high that Tsunade could see Reko being enveloped in a chakra cloak of sorts.
'This will not do. He is burning lots of chakra.'
Hesitant, she squatted properly and fully focused on guiding Reko. Even though her head was really close to that erect member floating in the water, she decided to ignore it.
'It is better than actually pointing at my crotch.'
When she was standing straight, she could feel that a few inches to and fro would make it rub against her crotch, making her feel anxious and distracted.
So, she decided to get down. Only her head was out of the water as she focused entirely on Reko's abdomen, making use of her knowledge in Fuinjutsu.
'Finally!'
Tsunade breathed a sigh of relief as she felt Reko controlling his chakra. Though, she still remained in her position just in case something happened.
Reko was experiencing painful burst of chakra in between the process and she did not want him to suddenly lose control.
In the process, she had many close encounters with Reko's thing. Reko moved slightly, shaking and moving after each burst of chakra which caused Tsunade's face to get rubbed against his….
'She did not see it, did she?'
Tsunade glanced at Shizune, only to find that she was busy helping Sakura.
Tsunade would not have stayed with Reko but his large chakra reserves had more chances of getting into an accident than Sakura.
More importantly, his large chakra reserves could not be handled by Shizune either. Not that she would have let Shizune get this close to that beastly thing floating down there.
'Fucking awesome!! I cannot believe she is staying down there patiently.'
Reko had been able to control his chakra from the very beginning. But when Tsunade came to assist, he could not help but want to keep looking at her naked body.
Luckily, he experienced erratic chakra bursts, causing Tsunade to stay there for him.
…
Four hours passed,
Finally, Reko had fully transformed his chakra into a purer form.
There were no more chakra bursts and no more chakra burning. The effects of the fruit vanished as only the effects of acidic water remained, burning slightly.
"It took quite a while."
Reko opened his eyes, he felt his chakra enhanced body before smiling.
"Indeed. But you managed to retain more than eighty percent, that's impressive."
Tsunade, still sitting under water with only her head outside, praised Reko.
It was no exaggeration.
Reko had managed to refine more than eighty percent of his total. The new purer form of chakra was a hundred percent more effective than the previous one, making it a great success.
"Yes."
Reko nodded, he had indeed lost 16% of his total reserves, but it was worth it. Totally worth it.
"What are you doing down there?"
As Reko glanced down, he noticed Tsunade's curvy body underwater as only her head remained outside the water, allowing him to have a good look at her curves.
But that was not the point, his erection was totally aligned with Tsunade's face, almost entering her mouth, her hairs even stuck to his thing.
"What? Are you embarrassed now?"
Why didn't you stop shaking then? It seemed as if you were really enjoying it."
Tsunade made a comment as she looked at Reko's surprised face. Only she knew how many times she had to avoid the thing from slapping in her face.
If Reko did not experience chakra bursts then she would not have had such experiences. She could only ignore it.
"How could I? I was very occupied with controlling my chakra. I did not even feel it."
Reko turned his face away, not looking into Tsunade's eyes. He was aware that Tsunade was squatting down there.
He had felt every touch, every time his thing brushed against her lips, her face, he felt it.
"I hope so."
Tsunade smiled evilly. Not saying anything about this matter anymore. She stood up, showing her huge breasts to Reko which he didn't take his eyes off.
"You have to keep up with this training. As it is the only place where you would be able to learn the Yin seal."
Already exhausted, Tsunade informed that it was going to be their daily routine until he learned the yin seal. She left as she said this, allowing Reko to have a very good look at her swaying butt as she moved.
She was not worried anymore. This was going to take months. She could not keep hiding her assets. She might as well let Reko enjoy, hoping that it would calm down that big erection.
As she mentioned, the Yin seal was comparatively easy to learn in the current environment. But it did not mean that it was impossible outside of here. It's just that the time taken would be a dozen times more.
'That kid was really awake the whole time. He was pretending to be struggling.'
Tsunade thought to herself as she stepped out of the water. After seeing his reaction, it did not take her long to realise that he was pretending.
The whole time he was shaking, moving to and fro to catch her off guard.
He was enjoying brushing it against her lips. She felt that the frequency of shaking was quite high but didn't find it suspicious because Shizune had also gone through the same process.
If not for Shizune being old at that time, exhausted of her potential and unable to utilise the pond's effects, she would also have learned the Yin seal.
'His talent in ninjutsu… I don't know how far he can go. Could he reach Jiraya's level?'
What was done was done. What mattered now was the matter of guidance for Reko.
She realised that the chakra storing technique would be easily learned by Reko. With that learned, he could basically learn the rapid regeneration technique and her super strength with ease.
There was nothing left for her to teach. In a month of time, Reko would be able to learn both rapid regeneration and yin seal.
Reko followed Tsunade, getting out of the water. He was also exhausted after controlling chakra for so long.
Shizune and Sakura had already left as the time it took for Sakura to transform her chakra was relatively less than Reko. They were already resting at the makeshift house far away from the pond.
'Woah !! I didn't expect her to let it be. Did she really not mind it?'
Reko looked at Tsunade, swaying her butt provocatively. He could feel his blood rushing down there after realising that he could do much more than training in this place.
'Good thing, the training is weeks long.'
Reko looked around, finally getting the time to enjoy the scenery.
Since he had trained for so long, now it was time to go on a little sightseeing.
Soon enough, dusk arrived and everyone was busy resting except for Reko. His Senju physique allowed him to have supernatural recovery.
As he strolled around the sacred land, he found numerous ponds, lakes, and even a water source that looked like a beach.
'This new chakra, it's purer, more refined. There is going to be a very obvious increase in my combat.'
…
Second day
This time, it was Shizune that came to assist him instead. Tsunade had already provided him with the yin seal which he needed to practice in the pond.
As hyped as it was, it did not take him more than an hour to get the Yin seal. For the next three hours, he continued to draw the pathway of the yin seal and finally connected it to his forehead.
It was the second day and he had already acquired the Yin seal.
The only disappointment was lack of Tsunade's presence. She had shifted to another pond, saying that the effects would be better like that.
"You did it? Already?"
Shizune seemed more than just shocked. Her attention shifted back from his body to his talent once again.
Even though she knew of Reko's talent, she still estimated that it would take him a week at the very least.
She believed that Lady Tsunade had sent her because it would take long for Reko to finally complete the seal. But the situation was totally out of her expectations.
"That was difficult. I am going to try and store my chakra now."
Reko gave her a calm smile as he began to try storing chakra in his Yin seal.
This new skill required his thorough understanding and he was happy to prioritise it over Shizune's petite build.
