Izuna, restore the glory of the Uchiha!

Such a high-risk ninjutsu cannot be practiced casually like the Great Fireball Technique; it must require professional supervision and guidance.

Of course, even the Great Fireball Technique cannot be practiced casually. After all, there aren't many ninjas in the Uchiha clan who know Water Release, and the forests near the clan's territory are very dense. One wrong move could lead to disaster.

Although the perpetrators are usually young children, patrol teams are always needed to quell these wildfires.

Tobirama's signal was quite clear, and Izuna had no way to hide.

However, he gestured to Tobirama to remain calm.

He wanted to confirm something first.

As Izuna lowered his hand to reassure Tobirama, the dictionary appeared before them.

In Izuna's view, new Flying Thunder God entries appeared on both his and Jiri's pages.

However, none of them were as dazzling as Tobirama's; the light on Jiri's entry was even weaker than his.

As he expected, the number in the lower right corner of the Flying Thunder God entry book did not change even though he had learned the basics.

It seems that there is not much room for maneuver until the "activity progress" truly meets the requirements of the entry.

I had originally hoped for some kind of skill point-adding function that could instantly increase his proficiency, but now it seems that was just wishful thinking.

Under the questioning gazes of Tobirama and Jiri, Izuna stared blankly into the air for a while. Just as Jiri was hesitating about whether to go up and practice first, wondering if Izuna-sama was having some kind of difficulty.

Izuna seemed to finally snap out of his daze, smiled at them, and then walked toward Tobirama.

He didn't explain why he had been lost in thought, even though Tobirama's probing gaze was more intense than his expectation of instruction.

Izuna also had his own homemade Flying Thunder God kunai, with his chakra mark imprinted on it. Even from a great distance, Tobirama could sense a chilling aura unique to the Uchiha clan.

He watched as Izuna deliberately planted his kunai in an open space, in a direction completely different from his own, and inwardly grumbled:

Even when placed in the same direction, the distinctly different chakra aura prevents any misalignment.

Izuna naturally hoped that his arrangements would be more reliable and did not take into account Tobirama's thoughts, although the two of them appeared to be clearly separated by the direction of the kunai, which was to the left and right.

"I need to activate the technique with chakra first, then envelop myself, then sense the mark and try to connect the two ends..."

Izuna recounted the process.

Tobirama nodded, and before Izuna could finish speaking, he made a pause gesture.

"The key is the channel between sensations, which I can't explain to you in words."

Facing his own kunai, marked in the distance, Izuna began to search for that ethereal feeling.

Tobirama's description was certainly very fantastical, but when Izuna actually faced the passage, he discovered that it was even more incredible than Tobirama had described.

However, he still had a way.

For example, utilize the brightness feedback mechanism of the encyclopedia.

He has now discovered a new way to use this cheat: whenever he makes a choice that allows him to sense the correct path, the Flying Thunder God skill will become brighter; if he chooses the wrong direction, the brightness of the skill will remain unchanged or even dim.

Therefore, from the perspective of others, his overall approach is actually developing in a positive direction.

Tobirama had to admit this.

As a sensory ninja and the inventor of the Flying Thunder God Technique, he was fully capable of sensing the direction in which Izuna's technique would be activated.

He chose the wrong direction, then miraculously corrected it easily in the next second; he chose the right direction and continued to move forward.

This is the difficulty of this technique, and Tobirama's confusion at this moment is how Izuna so accurately found the direction to move forward.

While he was sensing and thinking at the same time.

The accumulation of surgical techniques has finally reached a critical point.

The entry for Flying Thunder God shines brightly.

It's now!

Izuna's method of activating the technique was somewhat violent; he poured in almost all of his chakra without reservation, which meant that when he was thrown near the marked kunai, he inevitably suffered some serious injuries.

Whoosh—!

"Lord Izuna!"

Zhili ran forward in a bit of a panic.

Tobirama frowned, but followed quickly.

If you insist that Izuna describe what this feeling is like.

He would say it's like being thrown into a front-loading washing machine, having the door closed, the most violent washing button pressed, and then having to accept dry cleaning because the water pipes are broken.

The whole process happened in an instant, so much so that his body hadn't even fully experienced the extreme abuse before it was over.

But that doesn't stop him from feeling a little nauseous right now.

After confirming that Izuna was only pale and otherwise unharmed, Tobirama breathed a sigh of relief and stood up. If something had happened to Izuna here, he would have been in big trouble.

"Oh, right... I forgot to tell you."

Izuna was still unable to stand up completely, but he bet Tobirama's expression was full of schadenfreude.

"The ultimate secret of Flying Thunder God Technique is to endure for an instant and then deceive your body so that nothing happens. Of course, you can gradually adapt, but the former will be more effective in the early stages."

His guess was correct.

Because Tobirama immediately let out a miserable scream, which sounded no better than what he was experiencing now.

"Ugh!"

The incident started when Zhili saw that guy's smug face and suddenly launched an elbow strike that accurately hit his side.

Tobirama shouldn't only be wary of her illusions; clearly, as Izuna said when she first warned him, Chiri's martial arts skills are also quite good.

Before Tobirama could straighten up, Izuna stood up, dusted himself off, and believed that Tobirama's stomach was churning just like his own had not long ago—Chiri was putting in no effort whatsoever.

"Actually, it's not so bad."

Izuna pretended that the person lying on the ground in a sorry state wasn't him, and smiled politely. He heard Tobirama mutter a few words in annoyance, but he magnanimously ignored them.

While the two were exchanging sarcastic remarks, Chiri quietly prepared her kunai.

Even though Tobirama was not fortunate enough to receive her powerful compliments, he still pretended to look at her a few more times and offered some advice that was better than nothing.

With precedents set, not only did he focus on completing the technique, but he also paid close attention to the process after it was initiated.

She took much longer to activate the spell than Izuna, clearly being more cautious, but her appearance after completing the spell was much more elegant than Izuna's, and Tobirama gave her a few lukewarm compliments.

No one would point out that he was extremely annoyed at the moment. These two Uchiha learned everything so quickly, shattering his talent, which he was so proud of in the Senju clan, in just two days.

He had taught the Flying Thunder God technique to a few of his clansmen who he thought were promising, but those fools couldn't grasp the essentials no matter how much he talked to them.

This is one of the reasons why he was reluctant to comment much tonight—he simply didn't expect both of them to succeed on their first try!

Hashirama, of course, had no idea that he had secretly taught the Flying Thunder God Technique. That guy kept quiet about all ninjutsu except for Water Release, as if simply shouting them out would activate them.

Well, that's certainly true for him.

In short, Tobirama's mood remained complicated tonight. Unlike when he learned that Madara Uchiha had injected Hashirama's cell reagent and hadn't even developed a low-grade fever, the increasingly skilled Flying Thunder God technique of the two people in front of him couldn't save him from his terrible mood.

Why does the heavens favor the Uchiha clan so much?

He was so puzzled, and even somewhat indignant.

Tobirama's thoughts drifted through the long night as the two continued their practiced movements. Once they were both certain that they had successfully completed the spell, although they still looked somewhat disheveled, tonight's mission was considered a great success.
