Uchiha Kotogawa from Konoha

As Tsunade said, drawing the Yin Seal is quite tedious.

Holding a brush to draw the seals of the spell bit by bit, Nohara Lin's body was covered with dense seals and talismans drawn one by one.

Ordinary people faced with this kind of massive project, if they can remember [-]%, they are considered geniuses.

But this is nothing to the Uchiha family's Sharingan.

While watching and recording, Qin Chuan seemed quite relaxed and showed no signs of exertion at all.

"The nodes of the sealing technique need to be slightly changed according to the differences in each person's body. They cannot be copied completely. Not only will the Yin sealing effect be very poor, but it may also collapse. When the chakra integrated into the ink spreads disorderly, it will be It hurts the body.”

Tsunade said a few words, and waited until the sealing node in her hand was formed before starting to arrange the next node.

Qinchuan nodded slightly, looking very focused.

Only Nohara Lin, who was lying on it, felt very uncomfortable.

Of course, this didn't mean that Tsunade's arrangement of the vaginal seal made her feel very painful, but that she felt very uncomfortable when someone used a brush to smear on her body.

And it still takes three days, which is very painful.

A few hours later, Nohara Lin's whole body was outlined with black runes. This layer of black runes automatically disappeared and Tsunade began to draw the second layer of outlines.

Drawing and sketching in this way repeatedly, layer after layer, the short but long three days passed quietly. Tsunade painted a total of sixteen layers before and after. When the No. 16 layer was completed, Nohara Lin's whole body was illuminated by a layer of fine black. texture.

The lines are like flowing water, all gathered at the center of the eyebrows, forming a small water drop mark.

"Huh, okay, it's perfect. Just charge it and it's ready to use."

Tsunade shook her sore wrist and said with a smile.

Nohara Rin bowed slightly: "Thank you, Tsunade-sama."

Tsunade waved her hand and said meaningfully: "This is a deal between me and that stinky girl. She has already paid me. If you want to thank her, just thank her."

Nohara Lin was startled. She was smart and quickly realized another meaning in Tsunade's words.

Tsunade's deep intention was obviously the same as Minato's, and she wanted to make the relationship between Nohara Rin and Kotokawa closer.

"No need to thank me. Let's get dressed first."

Before Lin could speak, Qinchuan reached out and fished it out, and a set of black and white clothes appeared out of thin air.

Nohara Lin only noticed when she saw her clothes that her current situation was a bit embarrassing and her cheeks were slightly red.

"The Yin Seal Scroll, I need a week. Then you can come and get it." Tsunade said.

Qinchuan nodded: "Okay, I'll come back later."

After three days of busy work without sleep, Tsunade felt really tired, and she was ready to go back and take a nap.

"My suggestion is that you drink the little thing I gave you before. It should make you ten years younger."

Kotokawa's voice suddenly sounded, causing Tsunade to pause as she was about to walk out of the secret room.

"okay, I get it."

Tsunade didn't look back and disappeared through the door.

"Let's go back." Qinchuan turned around and said with a smile.

Nohara Rin is also looking forward to practicing the magic of immortality. With the Shangyin seal, she should be able to explode with strong combat power, and she might even be able to compete with Kotokawa Gogo.

With this feeling, Nohara Lin looked forward to it even more.

Three days passed in a flash.

After a few days of adaptation, Nohara Lin was generally able to control the opening and closing of the Yin Seal.

Now you have to continue to think about the balance of the three chakras in celestial beings.

Qinchuan took Lin to the primitive planet again, and the abundant natural energy poured into Lin's body like a siphon.

"Don't absorb it yet. I'll set up a barrier to isolate external natural energy."

Qinchuan warned.

If the endless stream of natural energy keeps flowing into Lin's body, then even if she has infinite chakra, something will happen to her sooner or later. Before she reaches the sage mode, too much natural energy will be harmful to anyone.

"I know, I won't mess around." Nohara Lin concentrated on controlling the energy in her body to prevent them from coming into contact with natural energy.

Just as Qinchuan was setting up the barrier, Lin suddenly thought of an idea, that is, whether the Yin seal could store natural energy.

This sudden curiosity is actually of no use. After all, pure natural energy cannot be controlled and used by ninjas.

But if it can be stored, there will be an advantage, that is, you don't have to stay here, and you can slowly practice magic at home.

With the two people at the center, a barrier ten meters in diameter slowly took shape.

During this process, Qinchuan tried his best to repel the air in the barrier outwards. The main purpose was of course to repel most of the natural energy. As for the air that was expelled, there was no need to worry too much.

There are also trees here, they produce oxygen.

"Okay, let's get started. Don't worry too much. I'll be watching from the side for you. Don't worry and try it boldly."

Qin Chuan patted his chest and said confidently.

Nohara Lin smiled: "I have an idea, please listen to see if it is feasible."

"I want to store natural energy into the Yin Sealed Space, so that we don't have to try it here. What do you think of this idea?"

"Uh?" Qinchuan was surprised: "It seems there is no difference between here and back there."

Nohara Lin bit her lip slightly and said angrily: "Of course it makes no difference to you. You don't practice immortality."

After saying this, Qinchuan seemed to realize something. She scratched her cheek in embarrassment and whispered: "Don't worry, no one will see it."

Nohara Lin stared at her with her big eyes, making someone immediately feel guilty.

"Just kidding, don't be angry. Otherwise, just like last time, absorb some natural energy and go back to practice. As for storing it in the Yin seal space, you can try it, but don't store too much. After all, the Yin seal is used To store chakra, the natural energy properties are different from chakra, so accidents may occur."

This explanation was quite serious, and Nohara Lin reluctantly accepted it.

Regarding the Yin Seal, Qinchuan has also been thinking about it these days. This technique relies on the sealing technique to outline it, just like a house, which is made of bricks, steel bars and cement.

The essence of the Yin-seal space is the same. It relies on sealing techniques and chakra to bond together to form a sealed spherical space.

But the Yin Seal is a technique formed with chakra after all. Kotokawa is a little worried that the entry of natural energy may cause an undesirable chemical reaction. If chakra and natural energy conflict, it will not be very beautiful.

Nohara Lin calmed down and began to absorb the natural energy free from the air. Kotokawa put a hand on her shoulder, invading a trace of chakra to experience the entire process of natural energy absorption.

At the same time, she also tried to absorb natural energy into her body, but this process was not easy for her, and she did not absorb any natural energy at all.

This made Qinchuan feel a little discouraged.

"Is this talent? It's really annoying."

Qinchuan spat, but had no choice but to continue trying to absorb natural energy.
