The daily Shuriken throwing warm-up went well even though Naruto took almost 20 minutes because he had to throw Kunai twice throw Shuriken once and throw Kunai while running three times
"Why don't we throw Shuriken while running too" Naruto asked while panting heavily because practicing throwing Kunai 5 times with its weight being 2/3 of a real Kunai made his arms quite tired.
Plus he had to channel Chakra to his hands while throwing to enhance strength and speed.
Even though it made him tired both physically and mentally it was good Chakra Control practice combined with Shuriken throwing at the same time.
If their friends or teachers saw this training method they would surely be shocked that they called this training which is beyond the ability of ninja students a. . .
"warm-up"
"It takes too much time. We only need to warm up. Today we will start serious Taijutsu training"
Naruto immediately perked up before taking deep breaths in and out channeling Chakra to circulate throughout his body to restore both Chakra and his body at the same time.
This daily action unknowingly increased his Chakra volume but Sasuke could clearly see it through the Sharingan. Increasing Naruto's Chakra is a path toward drawing out the Nine-Tails' Chakra without too much burden on his body.
Mirai told Sasuke that he had to train this way until Naruto was 10 years old before he could use some of the Nine-Tails' power and after that Naruto's Chakra Control and jutsu usage would have no problems
"But by then Naruto's power will develop by leaps and bounds. If you don't want to be surpassed you have to practice both Chakra Control and combining Chakra with Taijutsu to increase the volume and accuracy of your Chakra control Sasuke" Mirai warned while showing a glimpse of the future where Sasuke would be angry at Naruto for having more power even though he had always been weak an emotion that the current Sasuke didn't understand why he would be angry at Naruto
"Yes I will hurry and train so little brother Naruto won't surpass me" He said with a serious expression in his eyes and a slightly humorous tone because even if he were surpassed he thought he would never get angry not seek revenge or run after power following the snake's deceit
After 2 minutes of Chakra restoration Naruto nodded that he was ready before walking to face Sasuke who had just used a Kunai to draw a circle on the ground as the Taijutsu ring.
They started by fighting using only hands and arms then added feet and legs followed by channeling Chakra to wrap around their bodies. This was a progressive Taijutsu match starting lightly and escalating to heavily. In just 15 minutes Sasuke's Chakra was nearly depleted so he had to stop to rest.
Naruto immediately ran to eat the snacks he had prepared and threw one bag to Sasuke as well
"You are incredibly tough" Sasuke said while unwrapping the snack and eating it along with drinking an electrolyte drink to replace the sweat he lost "You endured my attacks for 15 minutes even though your defensive Chakra Control isn't very good but your footwork has improved a lot. You weren't thrown out of the ring like that time right"
"Of course someone taught me well. My footwork during the fight is much better but let me tell you I thought I would pass out from the heavy hits in the first 10 minutes but then I suddenly felt a strange power covering my body so I could continue fighting. But now I don't know where that power went. It made me dizzy" Naruto spoke while eating the snack making it a bit unclear but he still understood some of it
"The Nine-Tails' power is starting to flow into you but you can't control it yet" Naruto's eyes widened in surprise at Sasuke's words "That's good. Keep practicing like this every day. Before you turn 10 you should be able to draw some of the Nine-Tails' Chakra. But before you can do that your main Chakra capacity should be enough to control jutsu well before graduation for sure"
"Oh! I will train with all my might Crunch crunch"
Naruto quickly stuffed the snack before choking so he quickly drank the electrolyte drink causing him to gag.
Sasuke had to pat his back before ordering him to sit and channel Chakra to restore his body for 5 minutes before they would continue Taijutsu training.
The goal this time was the same 15 minutes. While waiting for Naruto to restore his energy Sasuke also quickly restored his energy but by sitting closing his eyes and meditating to send his consciousness to restore energy and train further in Mirai's personal dimension which is 4 times faster than the outside world. That means he would have 20 minutes to restore his Chakra
"I can't believe it. Naruto restores his energy in 5 minutes and is ready to train again but I need a whole 20 minutes" Sasuke complained softly before starting Taijutsu training with Naruto for another 15 minutes then rested and restored their energy for 5 minutes before going back to practice moving Shuriken throwing 100 pieces each aiming for 800/1000 points. Naruto threw 200 pieces but still couldn't get close to 800 points so Sasuke asked to go home for dinner first. Naruto nodded and waved goodbye before returning to practice seriously
"Right now my Chakra is 4 times less than Naruto's huh" Sasuke complained softly before walking to the convenience store to buy 2 bottles of electrolyte drink drinking one himself and walking back holding the other bottle for Naruto who was still practicing Shuriken throwing
"Oh You're back. Did you forget something?" Naruto stopped practicing and asked curiously
"No I brought this for you. Drink it and then continue training" Naruto grinned broadly before thanking him many times
