Naruto started cultivating immortality from creating the Six-fold Immortal Thief

The rock climbing of ninjas is very different from that of ordinary people. Just like climbing a tree, it requires the mobilization of chakra for assistance. The only difference is that climbing a tree only relies on the feet, while rock climbing requires the participation of all four limbs.

Now that Yusuke has locked their chakras firmly in his body, the auxiliary effect of chakras is gone. It is very difficult to climb a cliff more than 300 meters high with only the body.

As if hearing the worry in Kakashi's words, Yusuke smiled and said,"Don't worry, I will separate two shadow clones to wait under the cliff. If you can't catch it, I will ensure your safety!"

In order to reassure the two, Yusuke immediately separated two shadow clones and asked them to wait under the cliff.

Seeing this, Kakashi and the passerby walked to the cliff and began to observe the situation of the cliff. Without the assistance of chakra, the two of them had to choose a good route to climb the 300-meter-high cliff, otherwise they would be stuck in the air, which would be really dangerous.

Ninjas have strong intelligence collection capabilities, so it didn't take long for the two to find a route to climb the cliff and start climbing.

While the two were climbing, Yusuke also started his own training. He now had enough Senjutsu Chakra in his body, and he had successfully tried to use Senjutsu Chakra to nourish his body and soul.

Instantly entering the Sage Mode, Yusuke moved a huge stone from the side, put it on his back, and began to do frog jump exercises.

As the amount of exercise increased, the pure Senjutsu Chakra circulated in the body, was absorbed by the six internal organs, and converted into energy, substances and nutrients for the body to absorb. Yusuke only felt that his body was unusually comfortable, as if he had endless energy, and the intensity of the exercise was constantly increasing.

"Boom! Boom!……"

The ground was shaking continuously, and Kakashi and passers-by who had climbed dozens of meters on the cliff could feel it. They turned their heads to the direction of the shaking below, and were immediately shocked, because the mountain-like boulder on Yusuke's body was really exaggerated.

"Is this the intensity of your training? No wonder your strength is growing so fast!"

Seeing Yusuke's training method, Kakashi and the passerby looked even more determined, looked at each other, and climbed to the top of the mountain even faster.

"Senjutsu Chakra is better than I thought for the body's nourishment. In a short period of time, my physical fitness has improved more than the previous month's training, and even the strength of my soul is slowly increasing!"The morning passed quickly, and Yusuke stopped training because of hunger. His current body cannot allow Yusuke to absorb energy alone, and he must supplement the various elements lacking in his body through food.

Calling Kakashi and the passerby who were already sweating and exhausted, Yusuke and the other two soon came to the Chinese Pavilion. Today, the Chinese Pavilion is the most famous restaurant in Konoha and even the entire ninja world. If you want to enter the restaurant to eat, you must make an appointment.

Of course, as the son of the boss, Yusuke still has privileges. He has his own exclusive box. He asked the waiter to bring two large tables of food, and the three of them began to devour it.

After a while, the two tables of food were finished by the three of them.

Looking at Kakashi and the passerby who were slumped in the chairs with their stomachs held, Yusuke smiled and asked,"How was the training today?!"

The passerby was weak, and the feeling was not particularly obvious, but Kakashi could clearly feel the changes in himself. After thinking for a while, he said,"The effect is good. During the training process, chakra can actively participate in the strengthening of the body, making the training more efficient. I never thought that locking the chakra completely in the body would have such an effect."

Yusuke:"I have persisted in such high-intensity training for six years. Now you know why I am so strong!"

Kakashi and the passerby nodded to show their understanding.

Yusuke took out two scrolls and pushed them in front of the two. He had prepared them in advance, and whispered,"This is my first stage theory. It contains the use and unlocking methods of the seals I put on you. Go back and read it carefully, and then you will start practicing according to this theory."

Kakashi picked up the scroll on the table, frowned slightly and said,"You mean you won't train with us next!"

"That's right!" Yusuke nodded and did not deny:"My training has long passed this stage. Now my focus should be on the Sage Mode and the conversion of chakra in my body, so I can't accompany you to train."

After speaking, Yusuke looked at the two of them with a serious expression.

Kakashi and the passerby also knew in their hearts that it was impossible for the two of them to let Yusuke stop his training because of their own training, so they had already made psychological preparations in their hearts.

Besides, they still have Yusuke's training theory in their hands, and now they don't need Yusuke's company, so after just thinking about it, the two nodded:"Okay!"

The goal was achieved, and Yusuke walked out of the Zhonghua Pavilion contentedly and walked towards the Senju clan. He got the news that Minato Namikaze had completed the mission and had returned, and was now accompanying Kushina in the Senju clan.

As soon as he walked into the villa in the middle of the clan's land, Yusuke saw Minato Namikaze coming out of the kitchen wearing an apron and carrying a few dishes.

Seeing Yusuke, Minato Namikaze also greeted with a smile:"Yusuke, you came at the right time, come and have dinner together"

"Yes! Come and eat with us! How about trying the dishes made by Little Sun? Are they as good as yours?!"

At the table, Kushina also called him to come over quickly.

"Okay!"

Yusuke nodded and did not refuse. After practicing the Six Treasury Sage Chakra version, he could eat a lot of food even if he had just eaten. As for the food made by Minato, he could only let him taste it. After eating a little, Yusuke put down his chopsticks.

After the meal, Namikaze Minato looked at Yusuke and said,"Kushina told me about your situation. I also asked the people at Myoboku Mountain for you. They agreed that you should sign the scroll of Myoboku Mountain."

"Really? That's great!"

Yusuke didn't expect it to be so smooth. With the summoning scroll of Myoboku Mountain, he can go to Myoboku Mountain and refer to the Sage Mode there to improve his breathing method and Sage Mode, which will be of great benefit to his growth.

Namikaze Minato smiled, then went to the room to take out the summoning scroll of Myoboku Mountain. Yusuke picked up the brush and signed his name behind Namikaze Minato's name.

After signing, Yusuke and Namikaze Minato sat on the sofa beside them and started to communicate, but it was mainly Yusuke who was talking and Namikaze Minato was listening, and by the way, he gave Yusuke suggestions.
