Uchiha You did not rush into the village, but hid on a hill near the village. He waited until dawn to confirm that no Sand Village ninjas were around, and then he found the village chief who issued the task.

After showing the mission letter and forehead protector to prove his identity and purpose, and dispelling the village chief's fear of strange ninjas, the old man introduced the mission to him.

Jiusen Village is a small village that relies on logging for its livelihood. The villagers' daily life is to go up the mountain to cut wood and then weave the wood into rafts. When the water flow in the valley is the calmest, the villagers push the rafts into the river. The strongest people are responsible for releasing the rafts downstream and selling them at the river's mouth.

The money from selling wood was used to buy food, salt, cloth, iron tools, etc., which were loaded into small boats and towed back to Jiusen Village to meet the villagers' living needs. Because the area around Jiusen Village was all sloped more than 30 degrees, the village could only be located halfway up the mountain, and there was no land for growing food, so the purchased food was necessary to maintain the survival of the village.

But there was a problem with the river this year. The water volume was too small, and there were at least a dozen checkpoints along the way that the raft could not cross.

The villagers went upstream and checked the river for more than a hundred miles, but did not find the problem. However, going further upstream was beyond the villagers' ability, so they had to seek help from the ninja.

Although Jiusen Village is remote, the villagers are rich and knowledgeable. They sent people to the southern seaport to find the Konoha Village organization and issued a mission.

But this task is actually problematic.

Since there is no need to fight against ninjas, the mission level is only C.

Although the mission bonus reached the top 50,000 taels for a C-level mission, the mission goal was not only to find the problem, but also to solve it. The difficulty of the final goal was uncertain. Even to find the problem, the scope required for exploration was very large, and the final time was completely uncertain. If the round-trip journey was added, it might take more than ten days to complete the mission, and the average mission income was too low.

Not to mention that senior ninjas look down on it, even newly graduated Genin look down on it. Being away for more than ten days and traveling thousands of miles only ends up earning 50,000 taels. It's not cost-effective at all.

It’s even better to do the simplest tasks in the village and earn several times more money in just ten days.

This mission was left unclaimed for several days, and no ninja took it. It was finally taken by Uchiha You, who was determined to sneak out of the Land of Fire.

In fact, he didn't take this mission very seriously, otherwise he wouldn't have gone to the Cat Castle first when he went out, and it took him nine days to reach the mission location.

But in front of the chief of Kyumori Village, Uchiha You still behaved very professionally. He wore the Konoha forehead guard neatly on his forehead, his mission book was neatly arranged, and he asked for information in great detail, including when the water level began to drop, what the villagers found during their exploration, whether there were any dead fish or other animals, and whether there were any special plants falling.

As a result, we really found the problem. Six days before the water level dropped, there was a minor earthquake, followed by a minor flash flood. The flood was small but extremely turbid, and carried a large number of branches with green leaves.

Although the field investigation has not yet begun, Uchiha You has guessed that the reason for the decrease in water volume is most likely a landslide, and that a tributary of the river was blocked by the landslide, resulting in the decrease in water volume.

It is hard to say whether this can solve the problem. It depends on the specific circumstances of the terrain changes. If a landslide has formed a barrier lake, the problem will be solved as long as the barrier is carefully removed.

But if the terrain changed and the mountain moved, he wouldn't be able to solve the problem.

After all, moving mountains is one of the great supernatural powers that can reach heaven and earth, second only to chasing stars and taking the moon. It is a great supernatural power that Uchiha You dare not even think about.

If he really mastered this kind of magical power, would he still manage the Three Caves, plot against Uchiha Shisui, and plan to become the Third Hokage?

He should not be "He". The next second he will let the Third Hokage know that he is not Uchiha Yu. His real name is - Zugo Yu.

…

Uchiha You's wandering thoughts made him realize that his inner monkey was causing trouble again, which forced him to build a shelter after leaving Kyumori Village and heading north along the river.

When he carefully processed his wish and defeated the baboon with golden fur and blue face, turning it into spiritual nutrition to nourish his soul, it was already early morning of the next day.

Miwa Masayo was worried and reminded: "You, the time you spend dealing with Xinyuan is getting longer and longer, but the intervals are getting shorter and shorter. Is there any problem?"

Uchiha You, feeling refreshed, comforted the raccoon cat: "Don't worry, I chose the path of pure natural energy as my method and chakra as my technique. This is the hardship I should endure."

"Besides, the restlessness of the monkey in my heart is also the source of my progress. The more frequent and powerful the rebellion of this dead monkey is, the better the effect of my foundation building will be. Once I overcome this hurdle, everything will be fine."

"Well, hurry up, meow, you're too scary right now, meow."

"Thank you for your blessing."

"Let's go. We have wasted too much time. We need to speed up next time."

"The mission isn't unhurried, meow, why are you so nervous all of a sudden?"

"According to intelligence, the target of this mission may be a newly formed barrier lake. This thing is very likely to be an unscheduled natural disaster."

A landslide-dammed lake is a unique disaster in the mountains. Due to landslides or mudslides, the original river channel is blocked and water begins to accumulate, and the original river channel will become a new lake.

If the dam blocking the river is a solid rock, the lake can exist for a long time and form a beautiful waterfall at the other end.

But this is rare.

Generally speaking, a landslide dam is made of debris such as rocks, gravel, mud, and trees. Its strength is not guaranteed at all. Once the water level of the lake rises to a certain level, the dam will inevitably burst.

The accumulated river water mixed with the debris from the dam burst will create an impact more terrible than any mountain torrent. Originally safe places will be hit by the flood, often causing extremely serious casualties.

Uchiha You was a little worried that his employer was killed by the flood before he completed his mission.

He didn't care about the 100% mission completion rate, but causing the deaths of dozens or hundreds of innocent people due to his delay was different from killing the enemy who was endangering him.

What's more, Uchiha You is now facing an inner demon. Who knows if he will create a third heart shape in advance because of guilt, or if the inner monkey will degenerate into a demon monkey.

Uchiha You's intuition told him that it was very dangerous.

Uchiha You didn't dare to waste any more time, so he jumped into the deep valley and ran upstream along the river.

"Aaaah, I came here to escape the war, why is it more troublesome than in Konoha Village?"

"Meow?" Miwa Masayo tilted his head and suddenly said, "I remember you said, You: When the heart desires, greed arises, and greed without restraint leads to endless fatigue."

“…”

"Is this the sentence, meow?"

"You're right. I was too greedy. It was because I wanted to do everything at once that I put myself in this predicament."

"After completing the task, we need to slow down the pace no matter what."

"Miwa Masayo, after the mission is completed, let's play around and then slowly return to the village."

"Good meow!"

Only three hours later, Uchiha You went upstream nearly 260 kilometers, followed the dried-up river channel, and found the source of the problem that caused the water flow to be halved.
