"This is a tricky one. It doesn't have any hand signs, and you have to use your chakra to sense and extract as much poison as you can from the body," Mitsuru said.

"Even though this jutsu doesn't have hand signs, it's not like we don't need them at all. We have to use a hand sign that makes our Yang chakra more solid, but still ethereal enough to pass through blood without causing any blockage," Mitsuru continued.

Kaida nodded in understanding.

Then Mitsuru divided her chakra into yin and yang, dispersing the dome of yin chakra.

After her chakra was in a 70:30 ratio, she started performing hand signs.

By observing with his Sharingan, Kaida could tell the chakra became slightly denser.

After performing the hand signs, Mitsuru manipulated her chakra and transferred it into the mouse's body.

With the help of her chakra, she pushed the infected blood and poison out of the infected part of the mouse.

She then looked at Kaida and said, "This is what you have to do for now, but with enough experience and practice, you can do something like this."

Her chakra, which had only been present in the infected area, began traveling throughout the mouse's body.

She concentrated the poison, which had been dispersed in various parts of the body, at specific points. Then, using a scalpel, she made small cuts and removed the poison from the mouse's body.

With the help of Healing Palm Jutsu, she healed the cuts and the initial injury. After some time, the mouse opened its eyes.

"This is the advanced form of this jutsu. If you want to become a powerful ninja in the future, you should focus on mastering this jutsu," Mitsuru said.

"Just like I removed the poison from this mouse, you can remove poison that affects you," she added.

"Does that mean every ninja knows this jutsu? It seems way more efficient than Healing Palm," Kaida asked. "We can use pills and other methods to aid our healing, but if we get poisoned, we'd have to rely on this jutsu to save our lives."

"Do you think mastering it to that level is so easy?" Mitsuru replied. "It took me nearly two years to reach the point where I can use it on myself without side effects. What you said is true, though. Even if they experience some side effects, ninjas could save their lives if they practice for just 5-6 months. But the reason they don't is that it requires excellent chakra control, excessive practice, and some talent in medical jutsu. Even if a ninja meets all those conditions, many still choose not to learn this jutsu."

"Why don't they learn it?" Kaida asked.

"The reason is simple. For most ninjas, offense is the best defense. They focus on offensive jutsu in their early years, and by the time they become Jonin or elite Jonin, they're too busy with missions to learn medical jutsu from scratch," Mitsuru explained.

"That makes sense," Kaida replied.

"Enough chit-chat. Do you want to see it again, or are you ready to try it yourself?" Mitsuru asked.

"I'd like to see it once more," Kaida said.

"Okay, watch carefully," Mitsuru said, performing the jutsu on another mouse.

"Are you ready now?" Mitsuru asked.

"Yes, Sensei," Kaida said.

Mitsuru sat down and watched as Kaida practiced the hand signs for the jutsu.

Kaida practiced many times, and when he felt confident, he passed his chakra into the scroll.

Once again, a mouse came out of the scroll, also poisoned.

Focusing on the mouse, Kaida saw the infected area, and he knew the poison wasn't immediately life-threatening. It gave him time to learn without pressure.

Kaida passed his chakra into the mouse, attempting to push the blood and poison out. However, it wasn't as easy as he thought. The veins and arteries were fragile due to the poison, and when he applied force, the veins were damaged, causing blood to gush inside the body.

"Don't panic. Think about how to tackle this," Mitsuru advised from her seat.

Kaida thought for a moment, then used Healing Palm Jutsu to heal the damaged vein. After healing it, he started pushing the infected blood out again. Slowly, the poison and blood began to flow out from the wound, which he enlarged slightly.

After removing as much blood as he could, Kaida used Healing Palm Jutsu to close the wound.

"How do you think you did?" Mitsuru asked.

"Not well. Because of my initial mistake, the infected blood mixed with other parts of the body, along with some poison I couldn't remove. Also, when I tried what you did—moving chakra through different parts of the body—I realized it was an advanced technique. Not only was I unable to sense the poison inside the mouse, but I was also blocking the blood flow with my chakra," Kaida admitted.

"Good, you know your mistakes. Now, start practicing one jutsu at a time. Once you master this one, I'll teach you a more difficult technique. I'll be in my office, so if you have any doubts during your practice, come see me," Mitsuru said.

"Yes, Sensei," Kaida replied.

Mitsuru headed back to her office, while Kaida thought, 'Hmm, none of these jutsu are that hard. With my enhanced chakra control and the ability to see chakra with the Sharingan, I was able to learn them quickly. Now I just need to practice. Luckily, I have the perfect jutsu for that.'

*Poof, poof, poof… poof!*

Nearly fifty shadow clones appeared around Kaida. They divided into groups and began practicing the top three jutsu, while Kaida continued focusing on the Poison Removal Jutsu.

This jutsu required extreme chakra control and the Sharingan's ability to see minute changes in both muscles and chakra. Kaida decided to practice it himself.

******

While Kaida practiced, Mitsuru sat in her office, thinking, 'This is straight-up cheating. He learned the jutsu by seeing them just once or twice, and at this rate, he'll master them in 1-2 weeks, enough to use them for basic treatment. The Sharingan is truly overpowered. If not for the time it takes to master these techniques, this boy could reach my level in just months. Combined with his medical jutsu talent, it would be a great loss for Konoha if he dies on some stupid mission. I need to talk to Lord Third about this.'

She continued her paperwork.

(Seven hours later…)

'It's been so long… has he not come up with a single doubt?' Mitsuru thought.

As if on cue...

*Knock, knock.*

"Sensei, I've learned the jutsu," Kaida said, entering the office.

"WHAT?!"
