The system gives me immortality, and I will eventually become invincible while I’m alive.

In Jiugong Mountain, Chen Xun and Da Hei Niu packed up everything, left a note in the kitchen, and finally disappeared into the boundless darkness.

On the road.

They did not walk in the air, but kept using their body skills to shuttle through the deep mountains and dense forests, heading towards the sky and across the great plains.

"Moo!!~" The big black cow kept screaming on the road, rubbing against Chen Xun, and did not recover for a long time.

Along the way, the immortal cultivators I met were not very reasonable. Even if their cultivation levels were the same, they would compare their backgrounds and eventually fight.

Chen Xun held the bull's head in one hand and said thoughtfully: "Old Niu, maybe Yuanying monks are different from ordinary monks."

"Moo~" The big black cow snorted, feeling much more relaxed.

It looked at Chen Xun in confusion, as if he wasn't very happy.

"I have had a lot of contact with ordinary monks, but I look down upon the Yuan Ying ancestor, which is beyond my expectation."

"Moo?"

"First, this flower is the most precious thing in the Moon Tower and is also a specialty of Jiugong Mountain, but Ancestor Jinyu has no hesitation."

Chen Xun narrowed his eyes slightly, "Second, the probing power is not testing our strength, she is confirming our cultivation."

"Moo?"

"I can't understand the power of the Nascent Soul, but she definitely didn't use her strength, and she definitely saw something."

"Moo~~" The big black cow snorted and pretended to think. It felt that the Yuan Ying ancestor was quite reasonable.

"That sentence of 'If you need anything, come to Jiugong Mountain', sir, it won't be seen."

Chen Xun's heart skipped a beat, "Can the Nascent Soul Technique come to her?! Damn it..."

"Moo!!" The big black bull screamed in horror. Could it be that Chen Xun was taken advantage of?

"But what she said was too ambiguous. She had a certain degree of advance and retreat, and she was watertight. She has a bit of my style."

Chen Xun nodded lightly and stroked his chin, "Fortunately, we have been careful step by step and stayed here for so long, otherwise this matter would not have been settled so quickly."

Dahei Niu patted Chen Xun, with a look of respect for his elder brother in his eyes.

After spending so many years and patiently waiting for the best opportunity, I still have a lot to learn from my elder brother.

"Old Niu, you can't be careless in the world of immortality."

Chen Xun raised his head and squinted at Da Hei Niu's expression. He felt quite satisfied and said, "Follow me well. Yuanying Ancestor, you, Ximen Hei Niu, have a place for you."

"Moo!!" The big black bull kept rubbing against Chen Xun, almost grinning from ear to ear.

"Hahaha, head towards the Tiandu Great Plains!"

"Moo!!"

Arrogant roars like ghosts crying and wolves howling came from the mountains and forests on the road, which frightened all the demon beasts in the Qi Refining Stage and trembled in their nests.

But this trip to Jiugong Mountain also sounded a warning bell in Chen Xun's heart.

These Yuan Ying ancestors who have risen among many geniuses have deeper thoughts than the others, and they will never have a childlike mind.

And if you want to break through to Yuanying, you still have to suffer the calamity of refining your heart. This is the biggest reason why countless golden elixir monks fell in front of Yuanying Avenue.

The waves wash away the sand, and spiritual roots are only one factor that determines the path forward for cultivating immortality, but it is never the only one.

……

Two years later, in the west of Qian Kingdom, the Great Plains were cut off.

The endless vastness, the dead sea of ​​sand, majestic and quiet, the color is always monotonous.

Yellow, yellow, always hot yellow, as if the heaven and earth solidified the turbulent waves and emptying waves in an instant.

“It’s really good to live forever~ It’s really wonderful~~”

"Moo~~"

"Eternal life is really great~ It's really great~~"

"Moo~~"

"I am an alchemist~ you are an array master~~"

“Moo moo~~~”

The morning sun shines its rays onto the boundless plain, a strong wind suddenly rises, the sand waves jump, and the sky is stirred up with broken gold, and two figures gradually appear.

Chen Xun wore a worn-out straw hat and sat cross-legged on the big black cow. His singing was so loud that the surrounding sand and gravel surged up.

The big black cow also wore a bad straw hat and kept shouting and echoing. This song is still good.

It seems to be walking slowly, but it takes a thousand steps at a time, constantly revealing faint shadows on the ground, extremely ethereal.

"Old Niu, start diving and set up the formation."

Chen Xun looked around and shouted, "Start cultivating the elixir and refining the Infant Training Pill!"

"Moo~" The big black bull looked up to the sky and roared, and began to dive together with Chen Xun.

They had prepared everything along the way, and the distance they traveled this time was farther than last time.

boom...

Rumble.....

The ground was full of quicksand, and it was quite strange. Chen Xun kept observing the surroundings and frowned slightly, showing no aura at all.

It was as if he had been drained away by erosion. With his current peak golden elixir state, he could probably see something.

"Old cow."

"Moo?"

"The border town doesn't have spiritual energy, but Yuxu City, which is close to the Tianduan Great Plains, does have spiritual energy, but it relies on the spirit gathering formation."

Chen Xun grabbed a handful of sand and observed it, "It's very strange. The location of Yuxu City is not good either."

"Moo~~" The big black cow started dancing, "Moo moo!!"

"You think this wasn't like this before?"

"Moo moo~"

"At least when the city was built, the Tiandu Plain was definitely not like this!"

"Moo!" The big black cow nodded with wise eyes. It was born with spiritual awareness. There might have been spiritual energy here before.

"I'll go, Lao Niu, did you notice last time that we have been here for twenty years, but the consumption of spiritual energy is definitely a little more than in Qian Country."

Chen Xun's eyelids twitched, but he was still looking at the sand, "Is there something eroding the spiritual energy in Tianduan Plain?"

"Moo~~~" The big black cow snorted a long breath, it was really possible.

"Is there a super spirit-gathering formation? It sucks our spiritual energy? It belongs to his grandma."

Chen Xun suddenly became furious. It would cost a lot of wronged spiritual stones to restore his mana. "Old Niu, you know the formation, is that what you mean?"

"Moo!" Da Hei Niu also exclaimed. They saved their magic power when singing, and could feel even the slightest changes.

Something is indeed wrong. After comparison, at least hundreds more low-grade spiritual stones have been spent in the past twenty years!

It shook its head again, not feeling any power of the formation, as if it was always like this, and it was natural.

"After countless years, won't our Qianguo's aura become less and less?!"

Chen Xun raised his eyebrows. They were immortal and could definitely live to that era. "No wonder the top ten immortal sects want to take the lead in exploring the North."

Although the erosion of spiritual energy here is slow, as time goes by, the spiritual energy in various places may even dry up.

"Moo~" Da Hei Niu was thinking quickly and felt that what his elder brother said made sense.

In addition, the ten major immortal sects have a long history, and the Yuanying monks are also quite smart, so they should have discovered this problem long ago.

The big black cow snorted, looked at Chen Xun, slowly raised its paw, and gave a thumbs up.

"Old Niu, you see, as our realm improves, our structure and horizons open up instantly."

Chen Xun snorted coldly and waved the sand away with his hand, "I, Patriarch Chen Xun, should have a seat at the Yuanying seat!"

"Moo~~~!" The big black cow trembled with excitement. He and his eldest brother were finally going to succeed.

"Old Niu, let's go!"

"Moo!"

boom.....

After one day and one night.

Chen Xun took out his mountain ax to open up the cave, and the big black ox deployed a five-pole formation to stabilize the west. One person and one ox cooperated seamlessly.

They also began to cultivate elixirs together, and rare elixirs that exceeded the age of the elixirs were gradually growing.

Jie Jie Jie's strange laughter often comes from the underground cave, as well as the sound of the burning fire of the Heling Tree.

Unknowingly, He Lingshu has been regarded as a companion by Chen Xun and Da Hei Niu, and will stay with them forever and will never abandon them.

One person, one cow and one tree spent the spring, summer, autumn and winter in this underground cave, accompanying each other.

Above the ground, the sky is still full of yellow sand, empty and lonely, with no one coming and no one returning.

There is only that big sun lying quietly on the horizon, and the setting sun dyes the sand and gradually sinks into it.
