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

Over the past hundred years, they have continued to add more points, but it has no effect anyway. They add them casually, and they all add to the mana.

But after adding 90 mana points, they couldn't add any points at all, as if they were stuck in a bottleneck, so they had to focus on defense and speed.

Chen Xun also discovered that there is a top threshold for adding points, but after they break through, it won't affect anything. Instead, their first-pass strength will be greatly increased.

他们如今的长生点：力量50，速度71（50），万物精元50，法力90（50），防御90（50）。

In the past hundred years, Chen Xun had cut down quite a lot of Heling trees and was very interested in its characteristics, euphemistically calling it "research and study".

Because many disciples and senior brothers have also asked whether it is not good to cut down trees indiscriminately like this...

Naturally, Chen Xun would not tell them about his poverty back then. Everyone cares about face.

Only Da Hei Niu knows about this matter, it is their secret.

However, he also looked for the Millennium Crane Spirit Tree, and there was indeed one, but not many. It could be said to be a towering giant tree, but he punched it and gave it a concussion.

He was not very satisfied with the toughness and strength of the Millennium Crane Spirit Tree, which could not withstand his power.

In the end, it took half a day to cut down and drag it back to cultivate.

The big black cow was jumping around and asking Chen Xun to be gentle. This would be its future magic weapon material!

Then he spent several years cultivating it to ten thousand years, but the good guy didn't reach its limit. Chen Xun punched it away in anger, which still gave it a slight concussion.

Go on, extreme cultivation! It's not in the soil anyway, so I'm not afraid of it becoming a spirit.

After the first hundred thousand years, the Heling Tree finally showed signs of dying and began to turn black. A death aura slowly emerged throughout the elixir garden, and even began to affect the elixir.

Chen Xun and Da Hei Niu were so frightened that they screamed, "What's going on? Is this going to mutate?" !

Fortunately, they had reached the third level of practicing Water Spirit Technique and were able to keep the elixir intact.

For the last piece of wood, Chen Xun smiled and shook his head and said only one word, absolutely!

His current strength cannot move at all, and the mountain-opening ax cannot cut it, which is comparable to the Heling King of the Heling Tree Realm.

This huge piece of wood is constantly nourished by the water spirit art of the big black cow, covering its death aura. If it were an ordinary water spirit art, something big would have happened.

Chen Xun was working on a cauldron and refining weapons on the side, using the elixir fire cutting method... After the addition of mana, the elixir fire has become a magic weapon in Chen Xun's hand, specializing in fine work.

Like a master craftsman every day, he sat on a giant tree and continued cutting the wood with whitening elixir fire. A large black coffin filled with deathly energy was gradually taking shape.

The inside of the black coffin is filled with thousands of threads of spiritual vines that are thousands of years old. They are so densely packed that if anyone goes in, it will be a feeling that even Chen Xun would not dare to experience...

Dahei Niu also began to practice the method of cultivating magical weapons. He often used essence and blood to nourish him, just to achieve mind-to-heart communication.

Chen Xun makes a joke every day: A big black cow matches a big black coffin, hahaha...

The big black cow was so angry that it had to hump him several times every day. This big black coffin was its treasure.

This was made for it by Chen Xun himself, and even Chen Xun himself couldn't laugh at it.

However, Chen Xun still silently prepared a lot of elixirs for Da Hei Niu every day to restore his essence and blood. This black coffin seemed to make Da Hei Niu lose weight.

Chen Xun is not in a hurry about his own mountain-breaking ax. He has not found any good materials now, and Lao Niu's matter is more important.

Over the years, his weapon refining skills have greatly increased. He once joked about the Dan Fire Weapon Refining Technique: Brother Xun’s weapon refining technique is unique in the world of immortality!

Because of the "Three Yuan Pill", their cultivation level has gradually improved to the late stage of foundation building. After a while, they will be able to cultivate to the state of perfection, and then they can form the pill.

The quality of the 'San Yuan Dan' was also improved to top grade by Chen Xun. The biggest reason was because it used a lot of old elixirs.

The quality is different, and the utility is also very different, otherwise there would be no difference in quality.

Sanyuan Dan was originally used by monks in the middle stage of foundation building. That is because the alchemy hall of Wuyun Sect can only refine Sanyuan Dan of middle grade and below.

If it is top-grade or top-grade, it will also be useful to monks in the later stages of foundation building. This is the personal experience of Chen Xun and Da Hei Niu.

But Chen Xun was not confident in his alchemy skills, and he relied solely on the quantity and years of elixirs accumulated.

Although according to the normal life span of monks, they may have already passed away... but their path to the foundation building period has been smooth.

Because of their immortality, Chen Xun and Da Hei Niu have a very good mentality. They are diligent and steady in their cultivation and always do things calmly and calmly.

Chen Xun would occasionally go to the alchemy hall to learn about ways to break through the golden elixir stage.

There are at least twenty golden elixir stage monks in Wuyun Sect. It is impossible that they all have Tianlinggen.

But I did find out the method. Like the Foundation Establishment Pill, most of the monks in the Foundation Establishment Stage of the Immortal Cultivation World knew about it, but he didn’t.

It probably means that breaking through the golden elixir requires perfecting one's own spiritual roots, and then the golden elixir condenses in the body, and even strange phenomena can occur.

Whenever someone in the Wuyun Sect breaks through the golden elixir stage, the mountain must be sealed. Chen Xun and Da Hei Niu have seen this once in so many years.

At that scene, there was still a faint glow in the sky, as if someone had transformed into a flying fairy... They were almost about to perform a ritual.

And five-element mixed spiritual roots like theirs need to gather Jin Yuan Dan, Mu Yuan Dan, Shui Yuan Dan, Fire Yuan Dan, Earth Yuan Dan, five types of Five Elements Dan to forcefully break through.

Chen Xun's scalp was numb when he heard it, and the quality of this elixir must be at least medium-grade. Which sect would invest so many resources in the five-series miscellaneous spirit roots.

Most of the monks in the Qian Kingdom who can break into the Golden Core Stage have at least two upper spiritual roots.

Those who have broken through the spiritual roots of the three systems are all rare beings, and they must have received some great opportunity.

However, over the past hundred years, Chen Xun has also accumulated a lot of contributions, and changed the prescription of this Five Elements Pill. The elders of the Contribution Hall were not surprised.

This junior brother is a strange person. He is only in the early stage of foundation building, but he is now engaged in Qi refining stage spells, now he is engaged in Qi refining stage elixir prescriptions, and now he has begun to engage in Golden elixir stage...

But the contribution value belongs to others, and this junior brother also manages the elixir conscientiously, so they feel a little pity for Chen Xun.

When Chen Xun returned to the Spiritual Medicine Garden, he and Da Hei Niu were overjoyed.

Fortunately, there are few monks in the immortal cultivation world of Qian Kingdom who can form elixirs, so these rare elixirs are not needed in large quantities, so that they are harvested and become extinct like the foundation-building elixirs.

Over the years, these senior brothers have called them to help whenever they have personal matters. They have also harvested seeds in the elixir gardens of the sect for hundreds of years.

There are all these rare elixirs, such as Thunder Bamboo Fruit, Xuan Zhen Hua, Chalcedony Mushroom, etc. However, some elixirs actually take up to 800 years to be used.

The Wuyun Sect is also cultivated from generation to generation. When the year comes, people are sent to pick it, and finally it is treasured in the alchemy hall for future generations.

These rare elixirs and elixirs cannot be exchanged in the Contribution Hall. Just like the golden elixir period exercises, Wuyun Sect does not open such things at all.

Chen Xun sat on the boulder, gradually withdrew his gaze and said:

"Lao Niu, go home and prepare to clean up."

"Moo~~"

One person and one cow strolled towards the elixir garden. There was no sadness or joy in their eyes, only a light and peaceful look.
