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

"Old Niu, I have already made a century-old plan."

Chen Xun took out the pamphlet and put it in front of Da Hei Niu, "See if there is anything to add."

"Moo~" The big black cow nodded and stared blankly. The cow's head was still held by Chen Xun's hand.

"Moo!" The big black cow was a little anxious and quickly wrote to add.

They should also understand what was sold at those two auctions, and their knowledge should be counted in their practice.

Chen Xun suddenly realized and quickly added that there would always be omissions.

At this time, the sun was shining warmly, shining through the dense leaves, turning into golden spots that shone on the two figures.

They seemed to be writing furiously, and they seemed to be quarreling. The stream was clear and overlaid with the blue sky and white clouds.

Silently, this year's longevity points were added to the defense.

The next day, the plan begins!

First, to infinitely improve their cultivation, Chen Xun and Da Hei Niu announced the official closure of the cave and stopped all non-essential activities.

Dahei Niu was cultivating elixirs in the cave of the spirit beast room, while Chen Xun was refining elixirs in the alchemy room, and then they took the Five Elements Pill together and started practicing.

The hustle and bustle inside and outside the cave became silent, with only the sound of the wind and the flowing stream.

As spring goes and autumn comes, sometimes heavy snow covers the earth, and the sky and the earth are connected in a line.

The Heling Tree standing around is still strong and has a very tenacious vitality. Although it is common, if you think about it carefully, it can definitely be regarded as the most extraordinary tree in the world of immortality.

The inside and outside of the cave were still covered by the formation, there was no sound, it was quiet and harmonious.

It was the terrifying mana fluctuations that came from the cave from time to time, causing the Heling Tree to drop countless yellow leaves.

There are also many monks in Qinxian Mountain who have never returned. It must be that when they were exploring the secret realm together, they couldn't help but exchange their cultivation experiences and became possessed and died.

Yuxu City is still a scene of the prosperous age of the world of immortality. There are big monks waving tens of thousands of spirit stones, and there are young monks running around for several days for a few spirit stones.

The sky is still the same sky, but people are no longer the same people.

The years passed by, and suddenly looking back, only Chen Xun and the big black cow stayed together, never leaving their side, and they passed away after a hundred years.

tread……

tread……

A man and an ox slowly walked out of the cave. They were surrounded by magic power, and the dust was flying, as if they were clearing the way for them. The momentum was overwhelming.

The power of their consciousness instantly spread inside and outside the cave, and they remembered the changes in every place in their hearts, and were checking any suspicious places.

"hehe."

"Moo~"

There was coldness in their eyes, and they were letting out a low laugh. Every step they took was like stepping on the lifeblood of the earth.

There was even more rainbow light shining around him, and there were already roars. No monk dared to step forward and try such terrifying and heavy magic power.

Chen Xun and Da Hei Niu looked at each other in tacit understanding, and the corners of their mouths gradually began to rise.

Finally, with the accumulation of countless elixirs and elixirs, a breakthrough was achieved. The resources consumed were enough to make a large sect kneel on the ground, shouting that they can't afford it, so leave quickly.

A great monk in the middle stage of Jindan!

Their physique, magic power, and spiritual consciousness were all elevated to a higher level at the same time. That change made them immersed in it, as if it was the most wonderful thing in the world.

This is something that even the system cannot do with more points. The power of heaven and earth is so wonderful and vast that even immortals cannot get a glimpse of it.

And the Five Elements Pill has indeed reached its limit and can no longer improve their cultivation.

But the golden elixir in their bodies has grown a lot and is quite full, no longer feeling dry and dull.

"Old Niu, take a few days to rest and make the next century plan."

Chen Xun's eyes were calm, everything just fell into place, "Go down the mountain and buy two red lightning wolves!"

"Moo?!"

"I am happy today!"

"Moo~~"

"Hahaha……"

There was wild laughter and high-pitched bull calls from outside the cave, and the figure gradually disappeared outside the cave and went down the mountain.

These hundred years of longevity points have been added to defense, essence of all things, and speed.

他们如今的长生点：力量90，速度139（90），万物精元140（90），法力140（90），防御140（90）。

However, they completely missed this centenary event. After buying the meat, they went to inquire about the auction items.

However, an eight-hundred-year-old Yuchen grass appeared unexpectedly. After hearing this, they beat their chests and stamped their feet, shouting that the gods, gods and Buddhas would not give them face, and they were ready to go back and open an altar to practice.

But life is never perfect. A little regret may make the life of cultivating immortals full of beauty.

On the way back, they also went to the Xiuxin Pavilion and renewed their subscription for two hundred years.

They were received by a strange monk. In the end, he just said sincerely: I hope fellow Taoists will come again next time.

Qinxian Mountain, Huangjie Cave Mansion, night.

After Chen Xun cooked a sumptuous meal, they sat under the stars and began to discuss the future.

That Yuan Chen Ginseng has been cultivated by them and has countless descendants. All they need is Yu Chen Grass and Cui Rui Ye Baizhi to refine the True Yuan Pill.

"Old Niu, but we don't have to worry."

Chen Xun chuckled, scooping up the stream water in his hand, sparkling under the moonlight, "My ax technique, and your formation technique."

"As well as our natal magic weapon and our plan to earn spiritual stones, we will have to start a hundred years later. In the end, we only need to attend the auction conference."

"Moo~" The big black cow was smiling. It was not in a hurry at all. It had nothing to fear after following its big brother.

It also swung its hooves in the stream, with its eyes full of thought, and glanced at the Heling Tree inadvertently.

Chen Xun told it that he wanted to refine the alchemy furnace into a life-saving magic weapon. In fact, it also wanted to refine the formation flag into a life-saving magic weapon as a master control.

"What's wrong, Lao Niu?" Chen Xun also glanced at Helingshu.

"Moo!" The big black cow suddenly started dancing and mooing crazily.

"You want to refine a set of magic weapons for the formation flag? Do you want to use the Crane Spirit Tree to refine it?"

Chen Xun shook his head and laughed, "Have you forgotten that the formation flags require special materials to be refined? They are all full of..."

"Moo?!" Da Hei Niu suddenly became excited and ran to Chen Xun's side.

Speaking of this, a flash of inspiration suddenly appeared in Chen Xun's mind, and his pupils shrank: "Aura... Only in this way can we communicate with the world and use the momentum to achieve the effect of the formation."

He slowly looked at the Crane Spirit Tree. Isn't this tree a spiritual tree with its own spiritual energy?

However, most of the immortal cultivation world consists of ordinary crane spirit trees, which are too fragile and cannot be used as materials for refining weapons.

But Chen Xun and Da Hei Niu knew that when this tree reaches a certain age, its terrifying lifelessness and hardness are rarely seen in life.

As for the Crane Spirit Tree that can grow to such an old age, it must be in an extremely terrifying place where spiritual energy gathers, and reality does not exist at all.

"Okay, Lao Niu, I will give it a try when the time comes and help you practice a set."

Chen Xun looked thoughtful, "If we have enough spiritual stones, let's buy those weapons refining books and formation materials."

"Moo~~~" The big black bull kept rubbing against Chen Xun, almost going to heaven with joy.

"Lao Niu, I'm here, take care of it!"

Chen Xun snorted coldly, with a scornful look on his face, "I would like to see when the time comes, which great immortal is messing with me, and I will go to his dojo from now on to talk to him."

"Moo!!"

The big black cow was once again so impressed that he fell to the ground. He bathed and burned incense next to the stream, kowtowed step by step in front of Chen Xun, and paid homage...

Bang!

A flash of silver light flashed, and a fist bigger than a sandbag struck. The big black cow's head turned over and floated into the distance along the stream, with eyes full of bright stars.
