As an excellent Medical Ninja, Shizune certainly doesn't lack Yang Release Chakra. She can develop poison mist Ninjutsu, and she herself possesses Water Release Chakra, but she completely lacks Earth Release, which she needs to cultivate herself.
Ino doesn't demand that Shizune practice it to a high level, nor could she achieve that in a short time. She just needs to be able to condense Earth Release Chakra within her body.
As a standard Jonin with no special cheats, physical defects, or intellectual shortcomings, Shizune currently only has Water and Fire Release Chakra. There aren't many issues of mutual generation and suppression involved, so developing Earth Release Chakra isn't too difficult for her.
She also knows the Shadow Clone Technique and Multiple Shadow Clone Jutsu.
Her Chakra was barely sufficient, but with the aid of Shadow Clone and enough knowledge, she managed to condense Earth Release Chakra in four days.
The two took advantage of Tsunade's drunkenness and gambling to close their doors and conduct research.
If Orochimaru and Danzo were to research Wood Release, they would have to work on cells, but what could they actually discover? It would be purely by chance. Ino, on the other hand, could take a more unconventional approach.
She herself knows Flower Release and possesses the Mind Body Switch Technique and Spirit Transformation Technique. She could completely use her consciousness to occupy another person's body, perform Chakra circulation on their behalf, and use Flower Release abilities. The prerequisite for this method is that Ino possesses this ability, and the target also has the foundation to develop this ability. Can one grow crops in soil, but also in sulfuric acid? The foundation is indispensable.
The two repeatedly researched several times and felt that the general direction of this method was fine, so they immediately decided to try it.
"Tonton, pay attention and don't let anyone disturb us. If anyone comes, no matter who it is, wake us up immediately," Ino instructed Tonton to stand guard.
Tsunade was already drunk, and Ino's consciousness was about to enter Shizune's body. If they encountered an enemy at that moment, it would be very dangerous.
"Puu Puu!" Tonton nodded vigorously, then bared a mouthful of tiny teeth, meaning, 'If an enemy comes, I'll bite you!'
Ino quickly waved her hand. 'Are you a real pig? My consciousness isn't even in my body, why would you bite me?' She pointed at Shizune, indicating that Tonton should bite her instead.
Tonton's childlike intelligence made it a bit difficult to understand the situation. It looked at Shizune, then tilted its head to look at Ino.
Shizune bathed it, played with it, and carried it around everywhere, and she strictly demanded that no one eat pork. It definitely had a better relationship with Shizune.
"Puu Puu" It looked at Ino, as if to confirm again, 'Can't I bite you? Do I have to bite Shizune?'
This dead pig!
The two gestured at the pet pig again for a while, finally making it understand the current situation. Tonton nodded vigorously, indicating that it understood, then lay down by the door, anxiously standing guard for them.
Ino and Shizune immediately began their first experiment.
Shizune first took the medicine to keep her cells in an active state, making it easier for Ino to extract body energy. Her total Chakra amount was still a bit low for Wood Release, but fortunately, the two were only testing this possibility.
Compared to Spirit Transformation Technique, Ino was more proficient with Mind Body Switch Technique.
Both involve controlling a body, so her first thought was her clan's Secret Technique.
"Mind Body Switch Technique!" She formed a special hand seal and aimed it at Shizune.
Shizune offered no resistance, handing over control of her body to Ino, allowing Ino to try using Flower Release with the Chakra inside her body.
Ino tried a few times, but it didn't work.
The mental energy she brought over with Mind Body Switch was very strong, while Shizune's body energy was weaker. The combined Chakra was somewhat imbalanced, making it difficult to add the Yang Release nature transformation. The two coordinated for a while in the spiritual world, barely managing the first step. However, the subsequent blending of Water and Earth Release Chakra stumped Ino. It wasn't that it couldn't be done, but she didn't have the energy to manage both aspects simultaneously.
Trying to cleverly develop a Bloodline Limit using the Yamanaka Clan's Secret Technique was clearly a dead end.
"Is it my problem?" Shizune asked pitifully.
Ino was a bit dejected. The Yang Release Chakra hurdle wasn't too difficult for her, as she had somewhat anticipated it.
But the second step was too difficult. She had to dedicate half her mind to suppressing and controlling the Yang Release Chakra, which led to frequent errors in the blending of Water and Earth Release Chakra.
Ino didn't have the First Hokage's ability to achieve miracles through brute force; she could only take a refined approach.
Unfortunately, her "seals" weren't enough, and her Chakra control was a bit of a hindrance. She couldn't control the Yang Release Chakra. If she left Shizune to control it herself, Ino would be kicked out.
Mind Body Switch Technique can only have one person control the body; it's either one or the other, with no third option.
There was no choice but to switch to the second method, using Spirit Transformation Technique, adopting a two-person operation mode.
Ino rested for thirty minutes, then condensed Yin Style Chakra and used Spirit Transformation Technique to re-enter Shizune's body.
First, Ino would blend mental energy and body energy to create Chakra. Then, the two would divide the work: one would be responsible for adding the Yang Release Chakra nature transformation, and the other would add the Water and Earth Release nature transformations. They would mix the Chakra, then gradually inject the Yang Release nature transformation with life force, and finally create Flower Release Chakra according to unique meridian circulation routes and blending ratios.
A quarter of an hour later, Shizune spat out a large mouthful of blood.
Ino returned to her own body, also standing up with a wilted expression: "...Still can't control it."
Shizune lowered her head: "I'm sorry, it's my problem. My Chakra is too little. Perhaps I could..."
She carefully glanced at Ino: "Perhaps I could try the Akimichi Clan's secret medicine?"
Ino didn't say anything. 'Don't say that in front of me!'
She pondered for a few seconds: "Spirit Transformation Technique can directly transmit Chakra. I'll rest for a bit, then we'll try again."
The mental energy loss was quite significant, so this rest period was long. It wasn't until two hours later that Ino recovered the lost portion.
Spirit Transformation Technique is different from Mind Body Switch. Spirit Transformation Technique can directly transmit Chakra.
This time, Ino operated entirely externally. She transformed into a spirit body, then blended the Chakra within her spirit body according to the Flower Release method, and then infused it into Shizune's body.
The scent of flowers filled the air, and the room was permeated with the aura of life. Delicate branches even began to sprout from the cracks in the walls.
Tonton was incredibly surprised, continuously calling out "Puu Puu" without stopping.
"Is this your Wood Release?"
"Actually, mine is called Flower Release..."
"The quantity is too small, more, it's not enough, I can still withstand more, a little more!"
Ino infused it cautiously. Even in her spirit body state, her Chakra was significantly more than an ordinary person's, and the Wood Release Chakra, full of life force, seemed even more overbearing.
Shizune urged twice, forcing Ino to increase the output. As a result, there was too much external Chakra, Shizune's meridians were damaged, and she spat out another mouthful of blood, failing the third experiment as well.
