Chapter 121: A New Mangekyō Born! Side Effect: Lifespan! (Requesting First Subscription!!!)

After digesting the information in his mind, Ishihara narrowed his eyes.

His deduction was correct.

For the Three-Tomoe Sharingan to evolve into the Mangekyō Sharingan, the key lies in Yin Release chakra, altered after an emotional outburst, stimulating the special organ to undergo directed mutation.

The Mangekyō Cultivation Method works by constantly accumulating stimulation to alter the Yin Release chakra, causing the special organ to mutate!

In other words, it simulates the process of an emotional outburst to awaken the Mangekyō Sharingan!

Quantitative change produces qualitative change!

This thought flashed through Ishihara's mind, followed by a sudden inspiration.

"Can the first process be skipped, stimulating the organ to undergo directed mutation directly?"

He then shook his head; doing so would not be cultivation but biological modification.

Moreover, achieving directed mutation is too difficult; he currently lacks the knowledge base for it.

"But in that case, this secret technique still cannot meet my requirements."

Ishihara's brow furrowed tightly.

His goal was to have the Uchiha clan awaken several Mangekyō Sharingan in the short term.

Yet the Mangekyō Cultivation Method requires vast amounts of time to practice, spanning ten years or even decades.

This clearly does not meet his requirements!

"The time required to awaken the Mangekyō must be shortened!"

Ishihara fell into thought once more.

"There are two parts in the secret technique that can shorten the time: the quantity of Yin Release chakra, and the growth of the special organ."

"My research into Yin and Yang Release is still too shallow; I fear I cannot break through on the Yin Release front in the short term."

"Then I will start by promoting the growth of the special organ!"

With a direction established, Ishihara's train of thought instantly became clear, forming a rough framework.

The vast knowledge of medical ninjutsu he had previously mastered became incredibly active.

Stimulating cell growth is something Orochimaru did frequently during his forbidden experiments, so Ishihara was not lacking knowledge in this area.

Under the filling of this knowledge, the framework in his mind gradually filled up.

It finally became complete.

Ishihara let out a long breath, a smile appearing on his face.

【You have improved the Mangekyō Cultivation Method based on medical knowledge, creating the secret technique: Mangekyō Cultivation Method 2.0】

【Mangekyō Cultivation Method 2.0: Upon mastery, it awakens the Mangekyō Sharingan, but the side effects are extreme, drastically shortening lifespan!】

Although the side effects were severe, Ishihara was immensely satisfied.
