Project completed?

Once the whole room was saturated with chakra, Naruto created a shadow clone and told him to start writing the seals on his body.

Shadow clone was writing the main seal on the forehead suggested by Kurama. As seals started covering his whole body Naruto; started feeling the strain on his chakra network.

As more seals were written on his body he started feeling as if he was on fire. His eyes were changing colors. His shadow clone saw this and stopped writing seals on him. Naruto used his strength and asked him to continue writing do not stop until it was finished.

Kurama was watching this. He helped Naruto by numbing his pain receptors. Naruto was feeling good after this and asked Kurama how long can he keep this up.

Kurama said once you have finished writing the seal, I have to retract my chakra so it won't interfere with the seal. I see; thank you for your help.

Anbu's who was on watch for Naruto sensed there was an increase in chakra around Naruto's room. One of the Anbu was about to go check but was stopped by their team captain.

Let's wait said the captain. Another Anbu was about to argue with him. When their captain said it was all naruto's chakra he might be accidentally releasing chakra if go inside he might get afraid of us.

Inside the room, the seal was completely written on the body. Naruto gestured to his clone to dispel it so he can activate the seal.

Before the clone could dispel Kurama's voice sounded in his head to get some cloth and put it inside naruto's mouth so he cannot injure his tongue or bit the inside of his mouth.

Clone put the cloth in the mouth before dispelling. Naruto activated the seal first few seconds nothing happened, and after that, the seal started to glow in red color and started sinking into his body.

He was feeling pain like someone crushing him under the hydraulic press. He was screaming but no voice was going out because of the cloth inside his mouth.

After about an hour, he was unconscious the whole night gone by the next morning at about eight o'clock. He woke up he felt something has changed inside him.

Kurama's voice sounded in the head, kid you are either crazy or a pure genius. Naruto was confused for a few seconds. Then Kurama asked him to look into the mirror and at his hands.

Naruto stood up and saw his clothes were somewhat shorter than usual. When he looked into the mirror he was shocked his hair had grown by a few centimeters and had red tails at the end. Then he saw his eyes had changed, one was a blue and thin purple with a reddish shade ring near the end of Iris. Another was Purple with a reddish shade with a thin ring of the blue inner end of the Iris.

Then saw his palms as the left was blank right side had a yin-yang symbol drawn on it. Kurama then called Naruto inside his mindscape. Naruto came inside to see Kurama sitting on the grass looking at the lake in front of him.

Naruto looked around and saw lake water has become like a gel. He looked at the sky and saw the yin-Yang symbol and many seal lines coming above the lake and land around. Naruto turned to Kurama and asked what happened here?

Kurama thought for a second, it looks like the seal had worked fine there were not many missing links inside your Fuinjutsu project. well, there are some defects as you have noticed with your eyes. Rest is working completely fine those seals that are coming down are nature chakra that your body absorbed while you were unconscious during the process.

Naruto looked at the seals and called, they are like control rods in a nuclear reactor. then looked at the black space far away from him what is that?

Kurama looked at it and said; that is where Senjutsu/Nature chakra will be kept. Naruto then didn't you say I absorbed nature's chakra then how it's black? You are not a master of Senjutsu once you master it. It will become color with your affinity or where you learn it.

Your body is very sensitive to Senjutsu now, you can hide in plain sight now as no one be able to sense your chakra. So your Jutsu can't be copied with Sharingan and your Tenketsu are hidden from Byakugan.
