Training and adventure

Shikai looked at the dead bandits, satisfied with his first real confrontation. Unlike before he regained his memories, he wouldn't be as effective. Under the starry sky, he understood that each trial brought him closer to his goal of revenge. And Tsunade was becoming increasingly mentally unstable.

The sun illuminated the cobblestones of a bustling small town located in the heart of the Fire Country. Merchants shouted to attract customers, children played in the alleys, and the appetizing smell of food stalls filled the air. Shikai and Tsunade walked among the crowd, their steps guided by the vibrant energy of the place.

Tsunade stopped in front of an inn. "We'll stay here. I have a technique to show you, and it might change your perspective on medical ninjutsu."

Shikai, always curious and eager to learn, immediately settled into the room. "What is this technique?"

Tsunade gave him a proud smile. "The *Cell Activation Technique*. It stimulates an organism's cells, allowing for faster healing or even a temporary boost in physical abilities. But it's risky if misused."

She placed her hands in front of her, surrounding them with a luminous halo of chakra mixed with subtle lightning. "Watch closely. By incorporating a small amount of Raiton, this technique can not only heal faster but also revitalize muscles, enhance speed, or even prolong endurance."

Shikai observed, "But... isn't Raiton dangerous for cells?"

Tsunade nodded. "Very observant. That's why this technique is reserved for the most experienced medical ninjas. Too strong a dose, and you risk burning the tissues. Too weak, and you'll have no effect. Now, it's your turn."

Shikai concentrated his chakra in his hands, trying to imitate the electric halo that Tsunade had demonstrated. The chakra pulsed weakly, but it lacked intensity.

Tsunade shook her head. "Too timid. This technique requires extreme precision and perfect control. Try again."

Shikai tried several times, his determination evident on his face. Finally, after a dozen attempts, Tsunade smiled slightly. "Not bad."

After a few hours of intense training, Tsunade decided to change the subject. "Now that you have an idea of the *Cell Activation Technique*, I'll show you another use of Raiton: integrating it into weapons."

She took out a Kunai from her pocket and handed it to Shikai. "Look."

With impressive fluidity, she channeled her Raiton chakra into the Kunai, which began to crackle with electricity. "By channeling Raiton into your weapons, you can increase their cutting ability and even paralyze your enemies upon contact."

Shikai grasped the Kunai, concentrating his Raiton chakra as he had learned earlier. The weapon crackled weakly.

"Try this," she said, throwing him several shurikens.

Within an hour, Shikai succeeded in infusing the shurikens with a steady Raiton energy. He threw them at an improvised target through the window, and each impact left burn marks while slicing through the bark of a tree trunk.

Tsunade crossed her arms, impressed. "I didn't think you'd progress this quickly. With a bit more practice, you could easily use this technique in combat."

Shikai smiled modestly. In reality, with his Yellow Flash, he had already done it instinctively with his special kunai.

For the rest of the afternoon, Shikai focused on the *Cell Activation Technique*. With each attempt, he refined his chakra control.

Tsunade observed from a distance, offering advice when needed. She was proud of her nephew. Shikai never settled for mediocrity and always pushed his limits.

Once the training was over, Tsunade suggested they relax by exploring the town. "Come on, we deserve a little rest. And I saw a place where we can have some fun."

Shikai frowned. "Aunt Tsunade, are you sure? Last time, we had to run away..."

Tsunade ignored his remark, softly laughing. "Stop worrying. This time, I'll win."

But as Shikai had predicted, things took a turn for the worse. Within an hour, Tsunade lost a significant amount of money, accumulating a debt she couldn't repay.

In the middle of the night, as the town slept, Tsunade shook Shikai awake. "Get up. We have to leave. Now."

Still groggy, Shikai followed her as they fled through the dark alleys. Behind them, an angry group of creditors pursued.

"I told you this would happen!" exclaimed Shikai as they ran.

Tsunade shrugged. "Yes, but where's the fun without a little risk?"

They ran until they were far from the town, finding refuge in an isolated clearing. Breathless, Shikai collapsed on the ground.

"Tsunade-san, one day, these habits will really get us into trouble."

Tsunade burst into laughter. "Maybe. But for now, rest. Tomorrow, a new day of training awaits us."

Under a scorching sun, Shikai and Tsunade slowly made their way through an endless desert. The landscape, devoid of any shelter or shade, only accentuated the harshness of their journey. The stifling heat penetrated their clothes, making each step an effort. Yet, Shikai knew there would be no respite. With Tsunade, even a hostile environment became a training ground.

"Well, Shikai, this is the perfect moment to introduce an essential technique: the *Enhanced Chakra Strength*," Tsunade said, stopping near a sand dune.

Shikai, already exhausted from walking under the sun, looked at her skeptically. "...here, now?"

Tsunade crossed her arms, a stern smile on her face. "If you want to survive as a ninja, you must be able to adapt to any environment. This desert is an excellent place to work on your concentration and chakra mastery. So, stop complaining."

Tsunade picked up a medium-sized rock and threw it at her feet. "Watch closely. This technique allows you to temporarily amplify your physical strength by concentrating a certain amount of chakra in a specific part of your body. With good control, you can break a rock like this one effortlessly."
