The first day of month that Tsukiho had to retain herself from using chakra, she felt her powerlessness more than anything as she had to run away from a mare genin as her body was too small to fight with a twelve years old teen.
Though she knew her family would protect her, she didn't want them to have anymore pressure as her mother also fight with others without using her chakra. She was able to kill the genin that after her through a sneak attack.
At the end of the day she exhausted both mentally and physically with Tsunade and her mom's medical ninjutsu and fuinjutsu. After completely memorising them, she dragged her body in to the lake near home and took a bath.
At the second she slowly started to get used to her sneak attack tactics. She even started to marveled at how weak ninjas' defence is. Sometimes just a mild speed kunai attack was enough to take down life of a ninja. But after thinking about sometimes she shook her head as everyone she killed this two days was just some genins. The lowest in the food chain in the ninja world.
She simply made some small traps that she learned in the military training in her previous life as she took advantage of her home territory to full extent. Even after that she didn't lazed around as she also fought with one or two genin time to time.
At the third day she laid some traps and fought hidden mist genins and two chunins with all day until no energy left inside her. As usual she ended up getting some wounds as Tsunade complained while healing.
After more than a week, she slowly get used to her routine. At early she made some some traps using kunai, shuriken and some wood trunks. Then she started to beat some enemy ninjas to push her physical limits.
Then she took a little rest deep in the forest and went to catch some fishes. At afternoon she learned medical ninjutsu although sometimes they were interrupted by some enemy ninjas
As for yin seal, she slowly started to feel a huge density of chakra between her eyebrows. She felt that she greatly underestimate the power of yin seal as the purple diamond mark still didn't appeared despite having very huge density of chakra.
She started to study skills related to poisons with Shizune as it is a huge fatal weakness to her that others can take advantage of. Tsunade taught them how to make various poisons and how to make antidotes for them as she gave them many books to learn.
In free time she managed to read some of and gained most basic understanding of the concepts of making poisons and antidotes. After that she slowly studied about more complicated poisons and antidotes until she felt giddy and took a little break about more than three days.
As someone who went to medical college in her early days of her university life. She have advance knowledge of how the poisons combined with various enzymes and some cell in human body to the molecular level.
But she still marveled at the medical skills in this world as she didn't dare to say it was inferior to her previous world. As both worlds has its own specialities in medicine industry.
But she was sure about one thing, the key point to ninja world fast evolution is chakra and war. It reminded of her country that she served as it was also directly jumped in to the iron era from stone era.
Nevertheless she understood chakra did more harm to the world as she remembered the shinju tree Kagura planted. But she understood the importance of chakra to bring down Otsutsuki members.
At night she spent her time learning Uzumaki fuinjutsu and writing letters to her friends.
After more than two weeks she finally saw a little trace of purple mark between her eyebrows. Then she learned how to guide her chakra in to the seal as she somewhat understood how wasteful when she using chakra to perform ninjutsu. She had many techniques to got perfect chakra control but she was still wasted lots of chakra. With yin seal she learned how delicate and swift the chakra control should be.
When it come to fighting she felt the ninjas sent from other villages gradually reduced. As she sometimes had whole day to learn medical ninjutsu and fuinjutsu.
From Itachi's letters she got to know that in next month he also going to join the battlefield as she frowned at Fugaku's decision but she didn't say anything as she wrote back to him how she survived when she fighting here all day so he will have a certain awareness of the battlefield.
From Kushina she learned about Minato's team seven that made from Obito, Rin and Kakashi. It drive her to train more as she understood the storm is about to unleash.
She remembered her nanny Shoko who was sent to hidden mist village as a spy. And made some plans about the future.
At the twenty fifth day, she went out to buy groceries with Naori to the Land of Waves. Though the situation in Land of Waves is dangerous due to the chaos of the war. The civilians were still able to live somewhat peacefully.
At the border of the Land of Waves she could sense a lot of chakra signatures than previously in there. She looked at her grandmother who was putting everything bought into storage scroll.
Sensing her gaze Naori smiled at her knowingly. "Do you want to go there?"
"Can I?" She asked back.
"Of course remember sweetie your grandma is a big person in the village." She smiled.
"Really?" She absentmindly look at the civilians who are locking their doors and the other parties who are leaving the town.
"Yup, you too. You are the Uchiha princess. And heir to the clan remember?" She smiled mischievously.
"Hn" Tsukiho understood her intentions and turned her face away.
"Hahaha" she chuckled while ruffling her hair.
"Then let's go." Naori took her hand and vanished from there and appeared about two kilometres away from their previous position.
