Training Divine Skills

"Sasuke, I won't take your food for free. Here, this is a Green Spinach Pill. Consider it payment for the meal. I assume you know how to use it."

Akimichi Toribo took out a box, selected a green pill from three different colored ones, and tossed it to Umino Sasuke.

"I'm off. Don't forget our date tonight."

Akimichi Toribo leaped and disappeared into the forest, his voice echoing through the trees.

"It's a Green Spinach Pill!"

Umino Sasuke was overjoyed. This Green Spinach Pill was a rare treasure, only given in small quantities to Konoha's most elite Jonin. It was a top-tier Soldier Pill, not something one could buy even with money.

Currently, Konoha's Logistics Department classified Soldier Pills into four grades.

For ordinary ninja at the bottom, those expendable Genin without any connections, the Soldier Pills they received during missions were usually low-quality, the lowest grade available.

For members of Ninja Clans and the backbone of Konoha, the Soldier Pills they received during missions were official Konoha-issued, standard-issue Soldier Pills.

As for Konoha Jonin, the Soldier Pills they received during missions were special-effect Soldier Pills, high-grade items with doubled effects.

As for the Green Spinach Pill, it was only given in small quantities for S-rank missions or under special circumstances; it was truly a special-grade ration.

The Green Spinach Pill, while called a Soldier Pill, was actually more like a secret medicine for Chakra bursts. Once consumed, it could instantly increase the user's strength by at least three times for a short period, serving as a trump card.

Although the side effects were significant, they were negligible compared to its effects.

Such a valuable item was freely given away by the extravagant Akimichi Toribo. Other ninja would hoard such a treasure, keeping it as a life-saving trump card.

"If the Green Spinach Pill is this potent, I wonder how powerful the legendary Yellow Curry Pill and Red Chili Pill are. Still, I suppose besides that fatty Akimichi with all his extra weight, other ninja can't handle anything more advanced than the Green Spinach Pill among the three colored pills."

Umino Sasuke carefully tucked the Green Spinach Pill into his clothes, gaining a new understanding of Akimichi Toribo's gluttonous nature. It seemed he had to serve this gentleman well tonight.

Not to steal the Akimichi Clan's secret techniques, but for the sake of this Green Spinach Pill, he had to treat this gentleman with utmost respect.

"There's still plenty of time. Let's see how effective the Akimichi's Digestive Technique is first."

Umino Sasuke quickly channeled his Chakra, imitating Akimichi Toribo by stimulating the vagus nerve endings in his intestines with Chakra.

This step might be difficult for other ninja, but for him, who possessed infrasound internal vision, it was incredibly simple.

Since it was his first attempt, he used only a small amount of Chakra to stimulate his intestines, just to be safe.

Even with just a tiny bit of Chakra, the effect was surprisingly good. His intestines soon began to contract, and his stomach acid, bile, and digestive enzymes seemed to have a speed boost, secreting in large quantities and rapidly digesting the food in his stomach.

"Captain, have you developed Fire Release Chakra?"

Inuzuka Ryo saw Umino Sasuke's entire body turn crimson, like he was in a sauna, with steam rising all around him. He thought Sasuke had developed a second Chakra nature, believing only Fire Release could generate such intense heat from within.

"Mm," Umino Sasuke replied noncommittally.

Umino Sasuke quickly arranged for the three adoring Tejudo to go and train separately, while he himself sped off to the river.

"Phew, phew, phew... I'm so hot. My body has too much energy; I need to digest it quickly."

Umino Sasuke felt his heart pounding and his body filled with power, as if his blood was boiling.

Umino Sasuke quickly formed hand seals and immediately released a Ninjutsu: "Water Release: Mist Technique."

"Huh?" After releasing this D-rank Ninjutsu, Umino Sasuke noticed that the Chakra he had consumed was recovering at a visible rate.

In less than ten seconds, his Chakra returned to its peak state.

"This is great! I didn't expect such a pleasant surprise."

Umino Sasuke's eyes lit up, filled with joy.

He had just used the Akimichi Clan's Digestive Technique to digest a large amount of food, generating a massive amount of energy. While he couldn't store this energy as effectively as Akimichi Toribo yet, it was perfect for recovering Chakra and stamina.

Although it couldn't fundamentally solve his severe Chakra deficiency, it increased his training efficiency tenfold, even a hundredfold.

Even in extreme combat situations, this ability would be highly practical. Increasing the digestion speed of food and Soldier Pills to enhance recovery was a crucial means of improving battlefield survivability.

"Water Release: Mist Body Flicker!"

Umino Sasuke immediately used Mist Body Flicker. His Chakra indeed recovered to its peak state quickly. Moreover, the stamina consumed by the high-intensity Body Flicker Technique allowed him to release a large amount of pent-up energy, making him feel incredibly refreshed.

"Flash!"

"Flash!"

"Flash..."

With the rapid recovery of Chakra and abundant energy, Umino Sasuke continuously used Mist Body Flicker.

In the past, using Mist Body Flicker about ten times would deplete most of his Chakra and leave him exhausted. Now, he had used it nearly a hundred times consecutively and was still full of vigor.

"Perhaps I should try expanding the range of Water Release: Mist Technique to see how it works?"

Soon, the influence range of Mist Technique expanded from the original sixty meters in diameter to a hundred meters, and it continued to spread. Only when it approached two hundred meters did the Chakra recovery speed fail to keep up with the consumption required to maintain such a large-scale Mist Technique.

At this point, Umino Sasuke didn't rush to expand the Mist Technique's range further. He maintained it at two hundred meters and continued to train.

In just half an hour, he had performed nearly a thousand Mist Body Flickers. With extensive practice, the speed of Mist Body Flicker became faster and faster.

Maintaining the two-hundred-meter range of Mist Technique also became increasingly effortless.

"Ugh? The energy is gone so quickly?!"

Umino Sasuke finally felt his Chakra recovering more slowly, and his energy was no longer as abundant as before. Clearly, in just half an hour, he had completely depleted the energy within him.

"In terms of food energy conversion, it seems I'm far inferior to Akimichi Toribo. I must continue to learn and draw inspiration from him."

Umino Sasuke finally recognized the drawback of the Akimichi's Digestive Technique: it consumed a significant amount of food supplies.
