Naruto: Uchiha Youngjo's Konoha Spring

Chapter 126 Letter from the Ancestors
"This... isn't good." Shizune hesitated, but Tsunade pulled her to sit beside her without hesitation and gave her a set of bowls and chopsticks.

"You're welcome. Lord Hokage told you to sit down and eat, so just sit down and eat." Tsunade said.

It was clearly noon, but Uchiha Touma and Tsunade were drinking and chatting in the Hokage's office until the afternoon. Tsunade finally agreed and expressed her willingness to serve as the dean of Konoha Medical School and signed her name on the plan.

After Uchiha Douguang sent the old lady away, he resumed his official duties.

It was not until the evening that Uchiha Douguang returned home.

After returning home, Uchiha Douguang activated the Sage Mode. After confirming that Hei Jue was not peeping around, he opened the scroll given to him by the Slug Sage.

Afterwards, Uchiha Douguang input the power of the Mangekyō Sharingan and the senjutsu chakra into the two seals within the scroll respectively.

After the seal was broken, the chaotic words on the scroll began to arrange themselves and soon turned into clear Ninja language:

[Hello, descendant of the Uchiha clan. When you received and opened this scroll from the Slug Sage, you must have already activated your Mangekyō Sharingan and learned Sage Mode.]

"As your ancestor, I would like to express my regret for the important people who passed away when you opened your Mangekyō Sharingan, because I have also felt the same way."

[Also, I must remind you not to become obsessed with power. The path you and I have chosen is fraught with danger. Only by maintaining absolute composure can you have a glimmer of hope. This is also why I didn't leave the complete inheritance within the family. Most people in the family are blindly pursuing power. I hope you won't be like that.]

"This ancestor is quite interesting." Uchiha Douguang couldn't help laughing when he saw the ancestor's instructions at the beginning of the scroll. The words spoken by his ancestor were not Uchiha at all.

[You will find this scroll. I think you should have noticed that the Mangekyō Sharingan can cause blindness due to excessive use. At the same time, you should have discovered that natural energy can slowly repair the Mangekyō Sharingan damaged by the depletion of pupil power after practicing Sage Mode.]

[You may be wondering, can natural energy repair the kaleidoscope? ]

[Unfortunately, this is not possible. For example, the Mangekyō Sharingan is like a mirror. With use, cracks will begin to appear on it. The method for upgrading the Mangekyō Sharingan, as recorded in the stone tablet enshrined in the family shrine, can be understood as using pupil power of a similar origin as a furnace to re-melt the damaged mirror, making it stronger. Natural energy can only serve as a glue to delay the mirror's complete shattering.]

However, don't worry. There are ways to use natural energy to advance the Mangekyō Sharingan, but the requirements are quite demanding. I don't know which of the Three Sacred Grounds you learned your senjutsu from. While the Sage Modes of the Three Sacred Grounds are powerful, they were ultimately created with the body structures of slugs, toads, and snakes. This is why, even when the Sage Modes of the Three Sacred Grounds are perfected, they still bear traces of being non-human. [And the ultimate requirement for advancing the Mangekyō Sharingan with natural energy is a senjutsu perfectly adapted to the human body.]

Although the ratio of natural energy, physical energy, and spiritual energy in the Sage Mode of the Three Holy Lands is 1:1:1, the natural energy portion of their Sage Mode contains some transformational effects on the human body. This is why, after completing the training of the Sage Mode of the Three Holy Lands, the body will experience some degree of alienation. If one attempts to use natural energy to advance the Sharingan, this portion of natural energy will have the opposite effect. Therefore, only a Sage Mode that is perfectly adapted to the human body can achieve this.

[Junior, you're lucky. I've already completed this step. I'll write down the method for cultivating the human Sage Mode on the back of the scroll. However, I must remind you that if your Mangekyō doesn't have the eye technique that can reverse its own state like mine, you only have one chance to try.]

The optimal ratio of Senjutsu Chakra for humans is a delicate balance between physical energy, spiritual energy, and natural energy. I can't describe the specifics, but I've sealed a perfect amount of human Senjutsu Chakra within this scroll. However, caution is advised when experimenting. If the Senjutsu Chakra synthesized with this ratio becomes unbalanced, even the black rods of Myōboku-san and the special slime of Slug-sama will be unable to expel the natural energy within the body. It took countless attempts using my eye technique before I finally found the perfect balance before my eye power ran out.

"As your ancestor, I don't want the younger generations of my family to attempt this dangerous method of gaining power. However, if you need this power to protect something you cherish, then I can only wish you ultimate success."

[Also, I've sealed a section of my eye technique in this chakra crystal using a transcription seal. If you fail, this eye power will revert your physical state back to before you attempted to synthesize the senjutsu chakra. This is why I said you only have one chance.]

After this passage, there is a long description of the method of practicing the Sage Mode exclusive to humans, and a crystal that stores a special piece of Sage Chakra.

After Uchiha Douguang carefully read the training method, he picked up the crystal.

As soon as he got the chakra crystal, Uchiha Douguang in Sage Mode keenly discovered the special features of this sage chakra.

Compared to the 1:1:1 synthesis model of the three holy places, this chakra is very special. The ratio of physical energy to spiritual energy is a very special ratio, and the ratio of spiritual energy to natural energy is also the same.

"What is this ratio? The golden ratio?" Uchiha Douguang roughly sensed the specific numbers of this ratio, and finally suddenly realized that the ratio of the three energies of this fairy chakra was exactly 1:0.618, which was known as the golden ratio in his previous life.

"No wonder it's so difficult to synthesize." Uchiha Douguang held his forehead. Compared with the precise numerical ratios of the three holy places, the ratio of this special fairy chakra is an infinite non-repeating decimal. When synthesizing, one can only rely on feeling to grasp the delicate balance.
