Naruto and Kakashi walked to the said training ground and there was Yamato. Naruto waved. Minato suddenly appeared next to Yamato in less then a blink of an eye and folded his arms, looking dead serious.

"So how hard will this training be?" Naruto asked.

"It will be one of the hardest things you do." Minato said as they reached them.

"Okay." Naruto frowned. "So how will the training go?" Naruto asked.

"Form a shadow clone." Kakashi said and he formed one.

Naruto formed only one easily and looked at him curiously.

"Now Naruto, the clones one, follow my clone into those trees over there, out of sight." Kakashi pointed at the forest.

The clones did as told. The Kakashi clone turned to face the clone and once out if sight the Kakashi clone smir ked and closed the gap between them.

Naruto and Kakashi Waited for about six minutes. Until memories flooded their heads. Naruto turned bright red and looked at him, taking a shaky step back.

"Heh, neat promise clone me." Kakashi blushed slightly and chuckled to himself.

"What did he promise?" Minato and Yamato asked.

"...a secret." Kakashi said. "Anyways, you remembered out clones conversation. You can also gain experience from them. So if you were to train with a good amount of clones, you can get this done faster." Kakashi said.

"O-okay." Naruto calmed down.

Soon Naruto learned he had to cut a leaf with his chakra. He made enough clones to get every leaf off of a tree. There, they all worked to cut the leaf he held in two. Sakura and Sai would come by and watch him. Sai would sketch Naruto and his clones to pass his own time. They both decided to support him and cheered him on. Minato watched Naruto and looked at Yamato, who was prepared to seal the nine tails chakra in case it spiked. Naruto felt a small rip and his eyes widened. A clone looked down and parted his hands to see a small cut in the leaf.

Minato was shocked he already started to cut the leaf. Naruto looked at his clone and frowned. He pushed his chakra to the leaf and growled. All the Naruto's were focused and one had red eyes and growled.

"TO HELL WITH THIS!" The close growled and threw the leaf to the ground.

Another clone tackled and stabbed the clone and the red eyes one vanished. Naruto felt the experience flow in his and he stood there and collected it. He didn't notice his eyes were only half opened and shook his head and continued.

Kakashi read his book and glanced up every now and then. He spun a Kunai on his finger as he read. Yamato focused on the clones. Minato watched and spotted Sakura walk over with a basket.

"I made my special food pills for Naruto." She set down the basket.

"That's kind of you." Minato smiled.

"Sai is painting a bunch of pictures of Naruto training, something about preserving the moment." Sakura said as she watched the clones work their tail ends off.

Naruto was sweating his chakra was being spent. A few clones already vanished due to low chakra. Naruto tore the leaf a bit more and smiled. He then stopped and panted heavily.

"Naruto, release the jutsu and take a break, collect all the experience." Kakashi looked up.

Naruto released the justu he perked up, gathering the progress. He suddenly felt off. The world darkened and spun around quickly. He then felt the strength in his legs vanish and he collasped. Minato dashed over. Sakura and Kakashi ran over. Minato had caught Naruto before Naruto hit the ground.

"What happened?" Sakura asked.

"When training you feel fatigued only slightly. But with over one hundred of you and all that hitting you at one time, it can make someone pass out for days." Yamato summed his explanation.

"Don't worry Sakura, I'm okay." Naruto smiled weakly at her.

They took a break and Naruto found her food pills revolting but they did give him energy and chakra. He chewed about a mouthful and drank them down with water. Sakura was happy because she thought he enjoyed them. Naruto took a break for the day, but later, he would go right back to training.
