I, Uchiha Yu, am solely focused on cultivating immortality

Chapter 69 The Surprise Attack by the Sand Village Ninja

The exchanges with immortals and the experiences gained after breakthroughs can only have a temporary impact on the exploration and development of the lake.

Once everything was settled, Uchiha Yu continued his search deeper into the lake.

Fortunately, when Uchiha Yu broke through, the wind-attribute natural energy erupted and stirred, affecting a small part of the lake. The source of natural energy they were looking for was within this area.

Following the location he sensed on the day of his breakthrough, Uchiha Yu easily found the source of the natural energy, a brand-new crack hidden beneath layers of falling rocks.

Judging from the surrounding terrain, the cracks were formed during a landslide.

When the opposite mountain peak crashed down, violently striking the bottom of the valley, the enormous shockwave spread from all sides of the impact point, focusing at the corner of the valley and tearing a crack in the thick rock.

Uchiha Yu also discovered that the peaks on both sides of the valley were sedimentary rocks, but there were a large number of limestone rocks near the crack, indicating that the crack was very deep and extended into another type of rock stratum.

Moreover, the fissure is also a spring, with spring water rich in natural energy flowing out continuously, bringing natural energy to the entire lake.

Uchiha Yu collected some spring water and brought it ashore to study with Miwa Masayo. They both smelled a faint fishy smell, proving that there was a lot of life at the source of the spring.

Uchiha Yu said confidently, "It should be connected to an underground river. There are many animals in this underground river, but we can't determine the specific source of the natural energy for the time being."

"Unless we widen the crack and then drill in to explore further."

Masayo Miwa shook his head vigorously, "No, absolutely not, Yu, this is the end!"

This time, Uchiha Yu did not insist, but nodded in agreement.

Exploring underground rivers is too dangerous. Even if he solves the problem of breathing underwater, he still can't solve the problem of getting lost, which is extremely dangerous.

At the same time, underground rivers are different from normal rivers. The oxygen content in the river water is not stable, and even if you master underwater breathing, you cannot guarantee safety.

Many underground rivers, after flowing through rock strata for a certain distance, will become oxygen-free waters in certain sections because the rock strata absorb oxygen.

Entering such waters, even fish, except for those local, low-consumption species, will suffocate.

Uchiha Yu said, "There will always be hidden dangers if we don't explore further. Creatures from the underground river might enter the lake, which could pose a danger to us and the ninja cats."

Miwa Masayo frowned and said, "That's a source of natural energy, so it can't be completely blocked, but it can be blocked into a very small hole, which should at least be enough to prevent large creatures from invading."

"Great idea! Block most of the cracks, then set up multiple layers of traps, using traps that allow entry but no exit, to block and capture any underground river creatures that may appear."

"This will not only prevent the invasion of subterranean species, but also allow us to obtain information about underground rivers by studying the captured animals."

With the most important source of natural energy identified and the follow-up work plan finalized, the remaining tasks can be handed over to Cat Castle.

While monitoring the changes in the rift and the lake, Uchiha Yu and Miwa Masayo continued their focused exchange and training.

Even though they have exchanged breakthrough information, the communication between the two psychic contractors remains very important.

They were all immortals, but they each followed different paths of immortality.

Uchiha Yu relied on the settings of his previous life's novels, Taoist philosophical theories, chakra theories of the ninja world, and his own wild ideas, and through sheer luck, he forged his own path.

After his enlightenment, he clearly abandoned the system of cultivation novels and deduced his own Foundation Establishment stage cultivation method. However, there are still countless problems to try and solve in the actual cultivation. He relies heavily on communicating with his Daoist partner to inspire his creativity.

Miwa Masayo, having spent three years with Uchiha Yu, unknowingly absorbed Taoist philosophy and, combined with hearsay about the Sage Arts of the Three Great Holy Lands, developed his own unique understanding of Sage Path.

It was because he had been contemplating the path of immortality that Masayo Miwa was able to sense the surge of natural energy when Uchiha Yu reached the Foundation Establishment stage, and thus seized the opportunity to become the first Cat Sage.

Both immortals' paths to immortality were based on the five divisions of natural energy, and both started with fire-related natural energy, making their starting points very similar.

However, their understanding of the Dao of Immortality is not consistent.

Based on pure natural energy and incorporating the chakra ninjutsu system, Uchiha Yu embarked on a path to pursue the complete mastery of the five elements. His powerful and complex strength, coupled with a restless yet balanced mind, enabled him to purify the Uchiha clan's bloodline, tap into its deepest potential, and generate incredible supernatural abilities.

Miwa Masayo combined fire-attribute natural energy with fire-style chakra to generate fire-attribute sage chakra. Perhaps because it was too pure, it rejected other natural energies, so the raccoon cat embarked on a path of pursuing purity, delving deep into the power within the rules of fire.

As pioneers of their respective paths, they were completely unable to refer to traditional ninja sages, and therefore relied heavily on each other, needing the other's progress to verify whether their paths were correct.

Uchiha Yu's breakthrough led to a breakthrough that yielded decisive results, which was great news for Miwa Masayo. She needed to refer to her pet owner's knowledge to adjust her course of action.

Discussion and debate were their main activities when they interacted.

On the morning of the fourth day of waiting for the cat's blessing, the man and the cat were arguing about the techniques of using the natural energy of fire. When they were arguing heatedly, they suddenly made a sound of surprise at the same time.

Masayo Miwa asked疑惑地问道：“是だお ...

Uchiha Yu confirmed: "That's right, they are ninjas, and there are at least four of them."

Uchiha Yu quickly frowned and said, "All four of them are radiating murderous intent; they're not here with good intentions. Same as usual, I'll stand in front, and you provide support from the outside."

The tabby cat nodded, then casually used its Flame Leap ability, disappearing into the flames.

Uchiha Yu waved her hand, creating a strong wind that erased the traces her companions left on the ground and also dispersed the scent she left in the air.

Once he was sure the smell had completely dissipated, he began to pretend to pack his bags, feigning that he was about to leave.

A few minutes later, three ninjas appeared from the hillsides on both sides of the valley and the river to the south, and they subtly surrounded Uchiha Yu.

Uchiha Yu reacted immediately, dropping his baggage and drawing his straight sword in preparation.

The Sand Village ninja, who was climbing the dam at top speed, quickly approached and stopped at the edge of the shuriken's range.

After carefully observing Uchiha Yu's appearance, he shouted, "Konoha ninja, what are you doing here?"

According to the rules of encounters between ninjas, Uchiha Yu responded in the strongest tone: "I am a Konoha ninja, this is the Land of Rivers, a Sunagakure ninja. According to the rules, you have no right to ask me for information."

The Sand Village ninja on the left hillside quickly descended the mountain, stopping just before the shuriken reached the edge of its range.

He scoffed loudly, "According to the rules? Konoha genin, you're so naive. You should know that all rules are a reflection of strength. We have three companions now, you have no right to refuse our question."

"Otherwise, we'll have no choice but to take you down by force and then interrogate you slowly."

Uchiha Yuuhaku assumed a fighting stance and said coldly, "You can try."
