Only Anko Mitarashi, who had not yet become Orochimaru's disciple, nearly lost to a chubby kid from a branch of the Akimichi Clan, but it was a hard-won victory.
By then, the first-year Class A had completely defeated the second-year Class A, shocking both the school and Konoha.
Ling, however, found it quite uninteresting; apart from Uchiha Shisui, there was no one in the Ninja Academy who could withstand a single blow from him.
It was better to quietly research the basic runes of Sealing Technique. Perhaps due to incomplete inheritance, these Sealing Technique runes had no individual rune meanings.
Only a series of runes, summarized by predecessors, formed a rather simple expression of meaning.
Ling didn't know if it was because the Sealing Technique basic principles in the library didn't record it or if it had been lost.
Konoha was quite stingy; Ling searched through the entire library and only found some E-rank Ninjutsu, such as Rope Escape Technique and Voice Mimicry Technique.
As for Sealing Technique, he only found a single Line Lantern Array. The principle of this thing was very simple, and its release was also very simple, done with a single hand sign.
This was also the first Sealing Technique Ling learned, and its effect was somewhat similar to the Nara clan's Shadow Imitation Technique.
It could temporarily restrain the enemy's physical body with Sealing Technique runes, but the duration was short and fragile, easily broken free from.
It was better than nothing, but fortunately, Ling's original intention was to study the basic principles of Sealing Technique.
Sealing Technique could be learned slowly later; with a good foundation, learning anything would be fast.
For example, at this moment, Ling's main body was practicing the Healing Technique. After the Shadow Clone, who had been studying basic medical knowledge in the library, returned, Ling began to try learning this simplest Medical Ninjutsu.
The basic principle of this technique was to return Chakra to its original state, liberating it into spiritual energy and cellular energy, and then using this cellular energy to increase cell activity and accelerate their division.
Compared to the Mystical Palm Technique, which healed injuries in a few minutes, this thing could only shorten an injury that would originally take a week to recover to two or three days.
So, how to practice this technique? That's where the various small animals in the Death Forest came in handy.
When Ling was training before, a rabbit was accidentally severely injured by the aftermath of his Super Strength Fist, so it became Ling's test subject for practice.
Fortunately, although this technique was simple, it was also very safe. It wouldn't be like the Mystical Palm Technique, where if not controlled well, it would lead to abnormal cell proliferation in a certain part.
It might not sound like much, but if you change the name, you'll be familiar with it: it's a tumor, just a benign one.
Because the Mystical Palm Technique's recovery speed is too fast, it sometimes causes excessive cell division, which is why there's a saying that the Mystical Palm Technique shortens one's lifespan.
Because in this unscientific Ninja World, the Hayflick Limit actually exists, although this limit might be higher than that of Earthlings.
However, a cell can divide at most a hundred times before it dies, with its genes collapsing.
Logically, a Hayflick Limit of over a hundred divisions should be much more than the Earthlings' sixty or seventy divisions, meaning a longer lifespan.
But you forgot, the number of cells in the Ninja World's creatures is roughly twice that of Earthlings, so the lifespan is actually about the same.
Both start developing from a single fertilized egg. Although your Hayflick Limit is high, the number of cells needed to form an individual is also greater.
This is also why people in the Ninja World have stronger physical qualities and defensive capabilities.
In fact, even if the Hayflick Limit problem is solved and your cells can proliferate indefinitely, you would still die.
For example, Senju Hashirama; so many years after his death, his cells are still full of vitality, and when implanted into a human body, they will even proliferate wildly, no different from cancer cells.
Ling was also very curious about how Senju Hashirama died. Ling had two guesses: one was that Senju Hashirama's soul was severely wounded by Uchiha Madara in the Valley of the End battle.
He died due to severe soul trauma, which aligns with the original setting that he died from severe injuries. After all, Hashirama's body was still in excellent condition before his death, with no signs of aging or decay.
The second possibility was that Hashirama's own cells proliferated indefinitely, and he died due to insufficient nutrients.
However, this is a bit far-fetched. Hashirama's body was only so big; it couldn't proliferate indefinitely.
And Orochimaru, a scientist who once studied Hashirama cells, naturally knew that Hashirama cells had such strong vitality, almost infinite proliferation, which clearly meant eternal life.
Yet Orochimaru chose not to use Hashirama cells for eternal life, but instead consistently researched soul-based eternal life, constantly changing bodies at all costs.
Even if the Reanimation Jutsu caused a decrease in genjutsu resistance, he did not give up on changing bodies for eternal life, so he must have discovered something.
In the Ninja World, only soul-based eternal life can truly grant eternal life. For example, didn't Ōtsutsuki Hamura survive in soul form?
Even the Six Paths Sage's physical body died, and that was a Six Paths body, the first Sage in history, yet his physical body did not last forever.
How on earth could the toads, snakes, and Slug of the Three Great Sage Locations live for thousands of years?
Chakra and Sage Mode definitely hide some secrets, but unfortunately, Ling cannot figure them out yet.
Ling felt that his current strength was sufficient to subdue Full Elephant and Piercing Ox, but he was currently within Konoha Village's barrier, and any slight disturbance would be discovered.
It would be hard to explain then. Ling had managed to fool his way through after subduing the great snake last time, so to subdue these two Shikigami, he still needed to find an opportunity to leave Konoha.
Looking at the lively rabbit in his hand, Ling also showed a genuine smile. He had now learned the Healing Technique.
Next was the hemostasis technique. The principle of this technique was still similar to the Healing Technique, but the target object was changed to blood vessels.
This was a method for rapid hemostasis on the battlefield, because you might not have time to slowly heal injuries with the Healing Technique.
On the battlefield, every second counts, so it doesn't matter if the wound exists; only the blood vessels need to be healed. After that, simply wrap a bandage, and you have a brand new cannon fodder.
Since the hemostasis technique is specifically used to stimulate blood vessel healing, it now requires advanced knowledge: detailed names and locations of human blood vessels.
Ling's Shadow Clone memorized this stuff in one morning at the library, but he didn't memorize it for other animals.
However, to practice the hemostasis technique, he couldn't operate on himself, so he had to make the rabbit suffer a bit.
Ling, with great sadness and apology, used a Kunai to cut the rabbit's hind leg, and tears of guilt flowed uncontrollably from the corners of his mouth, because Ling thought of cold-eaten rabbit.
Shaking off the distracting thoughts, Ling used the Line Lantern Array to trap the struggling white rabbit, making its red eyes flash with "gratitude."
Although he didn't know the rabbit's blood vessel locations, Ling was already prepared: the Sensing Technique, which is the basis of Sensory Ninjutsu.
This technique, a D-rank Ninjutsu also learned at the library, could use Chakra to form a wave to detect the structure of a target within a certain range.
This thing was actually a technique used to check if passing personnel had any problems, similar to the security gate at an airport.
