"The energy that exists in the atmosphere and the earth outside of itself?" Lin Feng frowned tightly and repeated word by word.

"Not bad." Jiraiya nodded and said in a deep voice. "Except for ourselves, everything in the outside world, including the atmosphere, mountains, rivers, even trees, flowers, insects and fish, can be natural energy."

"Mountains, rivers, trees, flowers and plants can all be natural energy?" Hearing this, Lin Feng was shocked, two rays of essence shot out of his eyes, and he stared at Zi Lai Ye without blinking.

If it is really as Jiraiya said, then the immortal art is really too powerful.

The strength of a ninja largely depends on the amount of chakra in his body. And immortal cultivators, once they have achieved cultivation, can draw chakra from nature anytime and anywhere, which means that they can use ninjutsu without any scruples in battle, without worrying about running out of chakra.

This is simply perverted!

"That's true." Jiraiya said proudly. "As long as you are successful in the cultivation of immortal arts, you can absorb natural energy from nature at any time and use it for your own use. It's just that it's so hard that even I can't do it yet. ”

"Immortal art is so powerful, isn't it difficult to learn?" Lin Feng quickly calmed down and asked.

"Not only is it difficult to learn, but it's also extremely dangerous, and if you're not careful, you can lose your life." Jiraiya said seriously.

"Mr. Jiraiya, how do you say that?" Lin Feng frowned.

"The Immortal Chakra is extremely powerful, if you can't skillfully manipulate the natural energy, you will slowly turn into a frog." Zilai also said solemnly.

"Is it really exactly the same as what was said in the original book?" Lin Feng said secretly in his heart.

"Balance, the most important thing in the process of immortal cultivation is balance." Jiraiya said seriously, "Mental energy and physical energy, because they often create ninjutsu chakra, so maintaining balance is not a problem." However, it is extremely difficult to maintain balance after inhaling the natural energy of the outside world. ”

"How hard is it?" Lin Feng asked.

"It's hard, it's very hard." Jiraiya said, "I practiced for three whole years to maintain balance! ”

"Three years?" Lin Feng was taken aback.

Jilai is also the lowest qualified in the "Konoha Three Ninjas", but in the entire ninja world, he is also an extremely excellent talent, otherwise he would not have been accepted as a disciple by Ape Feiri. It took three years of practice to master the balance, how difficult was it?

"If you inhale too little natural energy, the Immortal Chakra will not be able to form. If you inhale too much, you will become a frog due to the influence of natural energy. Jiraiya continued, "If you absorb a little more, you can change back to your original form." But if you absorb too much natural energy, you will never recover after becoming a frog! ”

"It's death, right?" Lin Feng said softly.

"Hmm." Jiraiya nodded and said, "People who become frogs will continue to become part of nature, but they will never be able to change back to their original human form." Speaking of this, his face was serious and solemn, and it was already a little scary.

Obviously, when Zilai was also practicing immortal arts, he had encountered such a danger, otherwise he would not have been so impressed.

"Lin Feng, are you still planning to learn immortal arts?" Zilai also looked at Lin Feng and asked seriously.

"Of course you have to learn." Lin Feng said without hesitation.

"You ......" was taken aback. He didn't expect Lin Feng to insist on learning after learning that immortal cultivation had such a huge risk, which reminded him of his youth.

"My will is very strong, I must learn immortal arts." Lin Feng said word by word.

"Are you sure?" Jiraiya asked again.

"I'm sure." Lin Feng replied categorically.

"Good, good. Hahaha! Jiraiya suddenly burst out laughing. From today onwards, I will accept you as a disciple on behalf of Miaomu Mountain. ”

"Thank you, Mr. Jiraiya." Lin Feng was overjoyed.

"Don't be in a hurry to thank me yet." Jiraiya waved his hand and said, "Even if I want to teach you, you can't practice." The cultivation of immortal arts must be in Miaomu Mountain, otherwise I will not be able to ensure the safety of your life. ”

"Must be at Myoki Mountain?" Lin Feng's eyes lit up suddenly.

He had great respect for Miaomu Mountain, one of the three holy places for the inheritance of immortal arts, and he wanted to go very much, and by the way, he met the big toad immortal who was said to have the power of prophecy, but he didn't know how to speak. What he didn't expect was that Jiraiya actually brought it up himself, which saved him a lot of trouble at once.

"Yes." Jiraiya nodded and said, "The Toad Immortal of Miaomu Mountain, Lord Fukasaku, holds a broken immortal stick, which can knock natural energy out of a person's body and ensure the safety of your life while cultivating. ”

"Broken Immortal Stick? It turned out that the stick had a name. Lin Feng said secretly in his heart.

In the original book, the immortal Fukasaku of Myoki Mountain is indeed holding a pitch-black stick and has rescued Naruto who is about to turn into a frog many times.

"Mr. Jiraiya, shall we go to Miaomu Mountain now?" Lin Feng asked.

"Of course not." Jiraiya shook his head and said, "Miaomu Mountain is a holy land for cultivation, and no one is allowed to set foot in that holy land except for those who have signed a contract with the Great Toad Clan. ”

Lin Feng listened quietly and didn't make a sound, because he knew that he would also tell him what to do.

"You know spiritism, right?" Jiraiya asked.

"Yes, Mr. Jiraiya." Lin Feng nodded.

"That's the best." Jiraiya smiled, took off a huge scroll from his back, and spread it on the ground.

"Jiraiya-sensei, what is this?" Lin Feng asked knowingly.

"This is a contract with the psychic toad that has been passed down from generation to generation in our family." Jiraiya said. "Write your name in your own blood and put a blood stamp on five fingers."

"Hmm. I see, Mr. Jiraiya. Lin Feng nodded and said.

After signing the contract, as long as the chakra is condensed in the hand that signed the contract, and then the five handprints of spiritism, you can summon a powerful toad from Myoki Mountain for your own use.

"Miaomu Mountain, I'm here Lin Feng!" Lin Feng shouted excitedly in his heart.

He put his thumb to his mouth, bit his teeth gently, and then left his name "Lin Feng" on the contract with blood, and then soaked the other four fingers with blood and engraved them heavily on the contract.

In this way, the contract is made.

"Psychics!" Jiraiya clasped his hands and shouted in a low voice.

"Bang!" A white smoke flashed, and a small liaison baby appeared in front of Lin Feng's eyes.

"Give the contract to Fukasaku-sama, and let Fukasa-samaku use reverse spiritism to summon us to the past." Jiraiya said to the contact frog.

"Yes. Jiraiya adult. After the contact frog finished speaking, he disappeared directly.

Not long after, Lin Feng felt that his body was being torn apart by a huge force, and he suddenly entered the spatial passage.

"Is this reverse spiritism? It's also essentially a space-time ninjutsu. Lin Feng said in his heart.

A moment later, Lin Feng's eyes lit up, and a magnificent giant mountain appeared in front of him, with a magnificent momentum and amazing energy fluctuations.

It is one of the three major inheritance resorts of immortal arts, Miaomu Mountain!
