I, Yu Uchiha, am devoted to cultivating immortality

The exchanges of immortality and the experience after breakthrough can only temporarily affect the exploration and development of the lake.

When everything came to an end, Uchiha Yuu continued to search deep into the lake.

Fortunately, when Uchiha Yu broke through, the natural energy of wind broke out in a commotion, affecting half of the lake. The source of natural energy they were looking for was within this range.

According to the position he felt on the day of the breakthrough, Uchiha Yuu easily found the source of natural energy, which was a brand new crack hidden under layers of falling rocks.

Judging from the surrounding terrain, the crack was formed during a landslide.

When the entire mountain peak on the opposite side fell down and violently hit the bottom of the valley, huge vibrations spread from all sides of the impact point, focusing at the corner of the valley, and literally tore a crack in the thick rock formation.

Uchiha Yu also discovered that the peaks on the left and right sides of the valley were all sedimentary rocks, but there were a large number of limestones distributed near the crack, indicating that the crack was very deep and penetrated into another type of rock formation.

Moreover, the cracks are also springs of living water. Spring water rich in natural energy flows outward continuously, bringing natural energy to the entire lake.

Uchiha Yu collected some spring water and brought it to the shore to study it with Miwa Masashi. They both smelled a faint fishy smell, which proved that there was a lot of life in the source of the spring water.

Uchiha Yuu said firmly: "It should be connected to an underground river. There are many animals in this underground river. It is currently impossible to determine the specific source of natural energy."

"Unless we widen the crack and get in and explore deeper."

Miwa Masashi's head shook like a rattle: "No, absolutely not, Yuu, that's it for now!"

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

Exploring the underground river is too dangerous. Even if he solves the problem of underwater breathing, there is no way to solve the problem of getting lost. This is a very fatal danger.

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

After many underground rivers flow for a certain distance in the rock formations, the rock formations absorb oxygen, causing a certain section of water to become oxygen-free waters.

Entering such waters, except for local specialized low-consumption populations, even fish will be suffocated to death.

Uchiha Yu said: "If we can't explore deeply, there will be hidden dangers. The creatures in the underground river may enter the lake, which may bring danger to us and the ninja cats."

Miwa Masashi frowned and said: "That is the source of natural energy. It cannot be blocked, but it can be blocked into small holes, which can at least prevent the invasion of large creatures."

"What a great idea! Block most of the cracks, and then set up multiple layers of traps. Use traps with entrances and no exits to block and capture possible underground river creatures."

"This will not only prevent the invasion of underground species, but also gain some information about underground rivers by studying captured animals."

The most important source of natural energy has been clarified, and the follow-up work plan has been determined. The remaining work can be left to Cat Castle.

Uchiha Yu and Miwa Masashi continued to concentrate on communicating and practicing while monitoring the changes in the cracks and lakes.

Even if the breakthrough situation has been exchanged, the communication between the two psychic contractors is still very important.

They are all immortals, but they have taken different immortal paths.

Yuu Uchiha relied on the settings of his previous life novels, the theories of Taoist philosophy, the chakra theory of the ninja world, and his own random thoughts. After blending them together, he relied on absolute luck to find a path.

After his enlightenment, he has clearly abandoned the system of cultivation novels and deduced his own cultivation methods for the foundation-building period. However, there are still countless problems that need to be tried and solved in the specific cultivation. He has been communicating with Taoist companions to stimulate his own ideas. inspiration.

Miwa Masayo stayed with Uchiha Yuu for three years, and unknowingly accepted Taoist philosophy, coupled with hearsay about the magical conditions of the three holy places, he had his own unique understanding of immortality.

It was with the thought of immortality in his heart that Miwa Masayo could feel the natural energy riot when Uchiha Yuu was building the foundation, and took the opportunity to become the first Neko Sage.

Both immortals' immortal ways are based on five points of natural energy, and they both start from the natural energy of fire. Their starting points are very similar.

But their understanding of immortality is not consistent.

Based on pure natural energy and compatible with the chakra ninjutsu system, Yu Uchiha embarked on the path of pursuing the five elements. The powerful and compound power, and the restless and balanced mind enable him to purify the Uchiha family bloodline, tap into the potential deep in the bloodline, and derive incredible magical powers.

Miwa Masayo combines the natural energy of fire and fire escape chakra to generate fire senjutsu chakra. Perhaps because it is too pure and excludes other attributes of natural energy, Cihuamao embarks on the path of pursuing purity and digs deep into the power of the rules of the fire system.

As the founders of their respective paths, the two of them are completely unable to refer to the traditional ninja sage, so they are very dependent on each other and need the other's progress to verify whether their path is correct.

Uchiha Yu had an epiphany during the breakthrough and deduced the decisive results, which was extremely good news for Miwa Masashi. She needed to refer to the knowledge of the shit shovel to correct her direction.

Discussion and argument are their main activities together.

On the morning of the fourth day of waiting for Mao You, one person and one cat were arguing about the techniques for using the natural energy of fire. When their faces turned red, they suddenly made suspicious sounds at the same time.

Miwa Masashi asked doubtfully: "Is it a ninja?"

Uchiha Yu confirmed: "Yes, they are ninjas, and there are no less than four of them."

Uchiha Yu quickly frowned and said: "The four of them are full of murderous intent. They are coming with bad intentions. As per the old rules, I will block the front while you go to the outside to support them."

The civet cat nodded, casually used the flame jump, disappeared into the flames.

Uchiha Yuu waved his hand and stirred up a strong gust of wind, which eliminated the traces left by his companion on the ground and blew away the smell she left in the air.

After confirming that the smell had completely dissipated, he began to pack his bags, pretending 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 in the south. They vaguely surrounded Uchiha Yu.

Uchiha Yu reacted immediately. He dropped his bag and drew his straight sword to be on guard.

The Sunagakure ninja who climbed quickly along the dam was the fastest. He quickly approached and stopped at the edge of the shuriken range.

After carefully observing Uchiha Yuu's appearance, he shouted loudly: "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 country of Kawakawa, Sunagakure ninja, according to the rules you are not qualified to ask for my information."

The Sunagakure ninja on the hillside on the left quickly descended the mountain, and also approached and stopped at the edge of the shuriken range.

He mocked loudly: "According to the rules? The underground ninjas of Konoha are really naive. You must know that all rules are a reflection of strength. Now that we have three companions, you are not qualified to refuse our inquiry."

"Otherwise, we will have to capture you and then interrogate you slowly."

Uchiha Yubai opened the fighting stance and said coldly: "You can try it."
