After testing his jutsus, Fujin returned home and took another short nap. Later he revised his Fuinjutsu skills before having dinner at Yakiniku.

The next day once again started with an intense Morning workout.

In the afternoon, the team again broke up to train with Renjiro and his clones.

Renjiro looked at Fujin and said, "I have taught everything I know about Senju Taijutsu style. How much you manage to master depends on you now."

Fujin bowed a bit and said, "Thank You Sensei."

Seeing his humility, Renjiro's face softened. He said, "You had once said that the Sannins too don't have any Kekkei Genkai. One of the Sannin, Lady Tsunade, uses an advanced form of Senju Taijutsu.

She modified the style to compliment her perfect Chakra control, making it much more deadly. Your own talent with this style too is very high. So work hard on it."

Fujin nodded and said, "Yes Sensei. I'll keep improving it."

Renjiro continued, "Regardless, it's time to focus back on Ninjutsu and Kenjutsu. We will practice all your jutsus once. And then we will begin working on supercharging your jutsus."

Fujin instantly got excited upon hearing that. Renjiro noticed and squinted his eyes. He asked, "You have already tried it, haven't you?"

Fujin laughed nervously before confirming it. Renjiro sighed and said, "I hope you didn't end up destroying anything." To which Fujin obediently shook his head, saying, "Don't worry Sensei. I shot everything straight up in the air."

Renjiro asked, "Alright. So what were your observations?"

Fujin replied, "It takes a lot of time to supercharge jutsus. So it just won't be usable in battles unless I can bring the time down a lot."

Renjiro nodded.

Fujin continued, "Apart from that, I couldn't supercharge all my jutsus. Especially Rock Shield jutsu, which didn't improve at all. Great Breakthrough and Wind Dragon jutsu had the best effect on supercharging."

Renjiro said, "Yes, that's how supercharging works. While you can try to pour a lot of chakra into any jutsu, not all jutsus can be supercharged. The amount of chakra you can pour in also depends on your chakra reserves, chakra control, mastery of the element, mastery of that jutsu, and the jutsu itself.

Though Konoha lacks Wind jutsus, you are lucky to have wind affinity. As almost all of the rank C wind jutsus can be supercharged. As for the Rock shield jutsu, its capacity is very low. So don't concern yourself with it.

In the next few months, I'll be teaching all 3 of you how to supercharge your jutsus quickly in battle situations. Since your chakra reserve is the highest, you'll need to work the hardest here.

Taken from Royal Road, this narrative should be reported if found on Amazon.

Before we begin, do you have any queries?"

Fujin nodded and replied, "Yes sensei. I have a few. The first one is related to Rock Shield jutsu.

I can now perform the jutsu without any hand signs, but I still need to slam my hands on the ground. Do you know any way to perform the jutsu by slamming the feet down instead?"

Renjiro raised his left eyebrow and asked, "Why do you want to do that?"

Fujin answered, "It'll improve the efficiency of the jutsu a lot. I carry swords in my hands, so to slam my hands on the ground, I'll have to discard my swords temporarily, which doesn't seem to be a good idea.

If I can perform the jutsu with just my feet, I can just use it while I'm fighting with my sword. And if the enemy makes a huge attack on me, then I can just retreat back while slamming my feet on the ground and creating multiple Rock Shields."

Renjiro was surprised by Fujin's tactical thinking. He replied, "Good thinking. I never thought about Rock Shield jutsu along those lines. I guess your intention is to eventually use this for all Earth style jutsu, right?"

Fujin nodded, "Indeed, that will be very convenient."

Renjiro continued, "Unfortunately, it won't be possible. Or at the very least, it won't be easy. The hand signs for that jutsu result in Earth nature chakra gathering in your palms. Though you perform the jutsu without any hand signs, you do it by merely replicating the way chakra is molded when you perform the hand signs.

Doing what you said will be no different from creating a whole different jutsu."

Fujin quickly replied, "In that case Sensei, can't we create new Earth style jutsus that work in this manner?"

Renjiro shook his head and answered, "It's too difficult. While small jutsus are always created, what you are saying will completely revolutionize the jutsus of Earth element. At the very least, I can't do it.

Also, while your idea is very innovative, it's highly unlikely that you were the only one who came up with it. And considering that no such jutsu exists to my knowledge, it's safe to say that no one ever managed to create it."

Fujin was dejected a bit upon hearing this, 'Oh well, there goes one of my ideas to annoy the enemy infinitely.'

Seeing the dejected look, Renjiro chuckled. Fujin looked back at Renjiro and said, "So since I can't improve my Rock Shield jutsu anymore, can I get Earth wall jutsu?"

Renjiro shook his head again and answered, "No, that's a rank B jutsu. Though your chakra reserve is good, you shouldn't be dependent on rank B or higher jutsus till you are promoted to Chunin."

The answer was as Fujin expected. So he just asked his last query, "Sensei, while practicing with supercharged jutsus, I ran out of chakra very quickly. Do you know any more means of increasing my chakra quickly? After all, the training of infusing chakra into the body is barely giving any gains in that regard."

Renjiro had a slight disbelief on his face that Fujin actually asked this question. He replied, "Brat, do you think they sell chakra in grocery stores? Your chakra is already 4 times larger as compared to your teammates.

Be happy with that and don't get greedy. Also, don't bother searching for more means of increasing your chakra reserves. Other than hard work and natural growth, almost every method has some form of drawback that’ll highly restrict you.

As for the battle, you can always eat Soldier pills to improve your stamina. So don't bother with it."

Fujin was a bit shocked at how dismissive Renjiro was. He thought, 'Really, no other means? Sigh, I guess I was expecting way too much. After all, the current boost is already very high.

Oh well, I'll leave this issue to the future. If I really desperately need chakra, I can try to steal a Tailed beast.'

Thinking about Tailed beasts, Fujin sighed internally, 'How good it'd have been if I could just throw some Pokéballs and capture them.'

Renjiro asked, "Any more queries?"

Fujin shook his head and replied, "Let's begin sensei."
