Naruto: We are invincible

"It's already this late, and you're still in the mood to joke!" Xi Ri Hong punched each of them with a smile. "He is..."

"You haven't told me why you came to see us." Xi Ri Hong quickly changed the subject.

"We are here to train," Naruto replied, then looked at Anko, remembering that she still had a curse seal on her that had not been lifted.

"By the way, Red Bean," Naruto said, "I can help you remove the Heaven's Curse Seal now, are you ready?" Naruto asked. Red Bean almost jumped up with excitement and quickly nodded in agreement.

"You lie on the ground." Naruto said, and Anko did as she was told. Hinata and Kurenai stepped back a few steps to make room for Naruto.

"It may be a little painful, just bear with it." Naruto said, gathering chakra on his index finger. Then, he placed his index finger between Red Bean's sternum, just above her heart.

"Hey!" Red Bean said dissatisfiedly. "You are taking advantage of me, you know that?" Red Bean said, straightening her chest and deliberately shaking it in front of Naruto.

Naruto's face immediately turned red and he stammered, unable to speak.

"Anko, stop messing around and hurry up!" Yuhi Kurenai shouted, and Anko couldn't help but laugh.

"Cough cough."

Naruto cleared his throat and tried not to think about those inappropriate scenes.

Anko took a deep breath, while Naruto released a faint but very bright light from his fingertips.

The light was enough to stop Anko's heart, which meant that she was now dead.

"You killed her!" Hinata looked at Naruto in horror, but Naruto looked calm, as if nothing had happened.

"You know what you did, right?" Hinata asked worriedly.

"Of course I know. When the host of the Heaven's Curse dies, the curse will be automatically lifted." Naruto explained, and Hinata breathed a sigh of relief.

"Why should I let Anko go through that pain? The curse seal will disappear on its own." Naruto said, pointing at Anko's shoulder.

The three magatama on the Heavenly Curse Seal began to spin, making a hissing sound. As the magatama spun, a puff of black smoke gushed out of the seal, which gradually became smaller and finally disappeared.

If they hadn't seen it with their own eyes, they would never have believed that there had been a Heaven's Curse Seal on Hongdou's shoulder.

Naruto placed a finger on Anko's forehead and activated her body functions once again.

Hongdou slowly opened her eyes, as if nothing had happened.

"Is it over?" she asked nervously. She didn't know what she would do if Naruto said "not yet".

"You're free...free forever." Naruto said, and Anko jumped up excitedly, hugging Naruto tightly and spinning around happily.

"You're crying?" Xihihong teased with a smile. She saw tears in the corners of Hongdou's eyes.

"No way!" Red Bean quickly denied. "I have to go back and tell Kakashi-sensei the good news... Goodbye!" Red Bean said, and left in a hurry.

"I've never seen her so happy." Xihihong said with a smile, and at this moment, she suddenly remembered that she was pregnant.

“Well,” Yuhi Kurenai said, rubbing her belly, “I have to go tell Asuma the good news.

Goodbye!" After saying that, Yuhi Kurenai also disappeared from the spot, leaving only Naruto and Hinata.

"That's really interesting." Naruto said and Hinata nodded. They sat cross-legged on the ground facing each other.

"Now," Naruto said, "tell me, what is chakra?" Naruto asked and Hinata looked at him expressionlessly.

"Come on...seriously." Naruto said and Hinata sighed helplessly.

"Chakra is the energy within the human body, a mixture of physical and spiritual energy," Hinata replied.

"That's right." Naruto said and Hinata rolled her eyes at him. "We can use these two energies separately. For example, the Nara clan's shadow manipulation technique uses mainly mental energy, while the Akimichi clan's multiplication technique uses mainly physical energy. There are also some illusions, such as the illusions of the Second Mizukage, which are completely based on mental energy." Naruto explained and Hinata raised an eyebrow in surprise.

"I've never heard of it." Hinata said, Naruto nodded and continued to explain the origin and principles of chakra.

"Most of us create chakra by mixing equal amounts of physical and mental energy. Although chakra is powerful, it can lead to death if overused. This is because it is these two energies that keep our bodies functioning," Naruto explained and Hinata nodded.

"Senjutsu Chakra is a special kind of Chakra. It is created by absorbing natural energy and mixing it with physical and spiritual energy. This kind of Chakra is more powerful than ordinary Chakra. Do you understand?" Naruto asked and Hinata nodded.

"What if the ratio of these three energies is not equal?" Hinata asked curiously. "You just said that some ninjutsu will use more physical energy or spiritual energy." She added.

"If you absorb too little natural energy, you won't be able to enter Sage Mode. But if you absorb too much natural energy, you will turn into stone." Naruto said, reminding Hinata to be aware of the dangers of natural energy.

"Turned into stone?" Hinata asked fearfully.

"Natural energy is very powerful, so there are very few people who can master senjutsu." Naruto explained. "Only ninjas with huge chakra are qualified to learn senjutsu. If you absorb more natural energy than you can bear, you will be devoured by the natural energy and become a lifeless stone statue." Naruto explained, and Hinata nodded as if she understood.

"In addition, the method of practicing fairy arts is extremely secretive, and the people who can teach this kind of ninjutsu are rare. Lord Jiraiya learned the fairy arts from the Toad Sage of Myoboku Mountain, and Grandpa Hashirama learned the fairy arts from his summoning beast. And I learned the fairy arts from Grandpa Hashirama because the Nine-Tails is not good at fairy arts." Naruto said.

"The training of Senjutsu is divided into two stages. The first stage is to learn how to sense and absorb natural energy, and the second stage is to learn how to perfectly integrate natural energy with your own chakra to create Senjutsu chakra. When you have accumulated enough Senjutsu chakra in your body, you will enter the Sage Mode. At this time, your physical skills, ninjutsu, and all chakra-based abilities will be improved, and your self-recovery ability will be greatly enhanced." Naruto explained, and then waited quietly for Hinata to digest this information.

"Are you ready?" Naruto asked and Hinata nodded.

"I will leave a shadow clone by your side. If you lose control during training, my shadow clone will use the ability of the Hungry Ghost Realm to extract the natural energy from your body so that you will not turn into stone." Naruto said and Hinata nodded.

"To absorb natural energy, you must become one with nature. You need to remain absolutely still. Now, I will inject a little fairy chakra into your body so that you can feel the presence of natural energy." Naruto said.

Naruto concentrated for a few minutes and entered Sage Mode.
