"Artificial spirit vein......" Xu Xuan muttered to himself.

The main material of the artificial spirit vein is the spirit stone.

This spell is good, I really don't lack spirit stones now, if all the spirit stones on my body are replaced with low-grade spirit stones, they are worth at least three million or more, this is the standard of a miniature spirit vein, if you use the method of artificial spirit veins, plus the spirit gathering and circulation array, it is enough for a small sect to use it for hundreds of years, and it is worth at least a thousand years.

In addition, unlike the flow rate of the other world, the energy of the spirit stone is constantly being transported, and theoretically this spirit vein may continue to exist, and there will be basically no change.

"Build a spiritual vein in this world?" Xu Xuan thought to himself.

But the idea was dismissed on the spot.

There is no point in building a spiritual vein in this world, first of all, there is an upper limit in the world, at most it is about Jin Dan, Xu Xuan faintly sensed the feeling of breaking through the sky and soaring.

And I can't help myself, the world has been cleared, and there are no strong enemies to threaten me, and I am the strongest in this world, so I don't need cannon fodder.

The most important resources are basically all in your hands.

All things considered, building a spiritual vein in this world is his unilateral effort, and there is no benefit at all, Xu Xuan feels that he doesn't need to be a slave to others, and he has worked hard to promote the development of the times, but he can't get anything, isn't it a brain disease.

Maybe the next world can.

According to the law, the next world ceiling is likely to be Yuan Ying and Huashen, the world level is higher, the aura may be more sufficient, and it is undoubtedly very beneficial to build spiritual veins in that world and recruit more cannon fodder.

"Then the next world." Xu Xuan thought.

For the rest of this time, Xu Xuan stayed in retreat.

Research the method of bloodline fusion.

The most mature method is undoubtedly to use the Huang Ting Neijing Pill to plant bloodlines, and if there is an irreparable bloodline defect, then use the Taiyin Refining Method to repair it.

But another problem arises.

The Taiyin Refining Form Method can only be used once, and no one can use it a second time, otherwise it is equivalent to an infinite rollback ability, which is too rebellious.

"More research is needed."

Xu Xuan forgot to sleep and eat to study the Taiyin Refining Formation Method to see if he could fall into a deep sleep like the last time, and his lifespan would not change, and then return to his peak.

There are two places that need to be studied next, one is how to perfectly fuse the bloodline, and the other is how to refine the form of Taiyin.

There is no spring and autumn on the moon, and Xu Xuan can't go out, after all, the passage hasn't opened yet.

When he had nothing to do, Xu Xuan occasionally practiced the pill and made preparations for the pill.

The most significant invention in the mirror realm is undoubtedly a variety of pills that break through the realm, such as Zhuji Dan, Jiedan Pill, Yuanying Dan, etc., if a person breaks through the success rate of Zhuji Dan is 30%, it can be increased to 60% or even 70% with Zhuji Dan.

Of course, there are also geniuses who don't need to build Ki-dan and break through directly.

However, most people still use pills, after all, failure to break through will lead to foundation damage, and the next time you rush through the level will be more difficult.

Xu Xuan didn't know if he needed it, and he didn't have the main material for the pill now, so let's talk about it later.

Time passes.

The world is so depressing that you can barely get out, and you're trapped in a place the size of this small town.

It could be a thousand years, it could be 10,000 years.

Of course, it could be hundreds of years.

In fact, this feather ancestral land is not too difficult to get out, it can be determined that it is underground, and the feather people should be able to come in and go out freely, due to the thin aura, the relevant formation is invalid.

Or keep digging up, keep digging, digging for decades or hundreds of years, and finally dig out the center of the earth, there is a phoenix real fire, and you are not afraid of these things.

There are no years in the ancestral land of the feathers, and I don't know how long it has been.

The Yin Wind Cave on the other side of the Mirror Realm has changed for several generations, and the highest cultivation is no more than the foundation building, either conspiracy or killing.

In the end, this mirror was completely hidden in the treasure house, and no descendants knew about the famous mirror fairy.

Time will erase everything.

this day.

Bronze Treasure Hall.

The wind is surging, the wind is gusting, and the shadows of the trees are swaying.

Under the Sycamore Divine Tree, the Taoist did not move at all, staring closely at the Dan furnace.

Bang!!

Suddenly, the lid of the Dan furnace flew off, and several golden rays of light flew out.

Xu Xuan grabbed it, and the golden pill was suspended in the palm of his hand, about three, which was brilliant and pure gold.

This is a variety of pills sutured, Xu Xuan called it an out-of-print Sun Huangting Inner Pill.

Xu Xuan was not in a hurry to take it.

Instead, he came to the outside world and made a sarcophagus out of stone.

Put the sarcophagus into the bronze temple, take out the jade bottle from the storage bag, pour out the pure gold liquid, and then cast a spell to summon water, and soon, the pure gold liquid filled two-thirds of the coffin.

This is a potion of Sun Feather human blood combined with a variety of materials to ensure that the corpse does not decay.

He also researched it, and the Taiyin Refining Form Method could not only be used once.

The key is that the quality of the potion used to refine the form should not be too low, otherwise there will be a situation where although the life span is not frozen, but the normal passage will occur, and it will naturally die in a deep sleep.

In the past, the liquid of the Taiyin refining form was phoenix blood, but now this Sun Feather human blood should not be much worse, so it can freeze lifespan.

Xu Xuan swallowed three golden pills containing the blood of the sun in one gulp.

Rumble!

The blazing energy exploded in the depths of the bloodline, Xu Xuan's whole person was as red as a shrimp, the meridians were broken inch by inch, and the crazy energy raged all over his limbs.

This brought irreparable damage all at once.

Xu Xuan decided to absorb the bloodline in the potion.

His purpose is not to turn into a demon, nor to become a bloodline cultivator, but to absorb its supernatural powers, just like a double pupil, not to become a phoenix or a feather man.

Therefore, the absorption is simpler, and there is still room to divide half of the blood to make the Refining Potion.

Bang!

The coffin closes.

After a long time, there was no movement in the coffin, and it fell into eternal peace.

Xu Xuan did not move the bronze temple, but put it in place.

If you don't succeed in breaking through the Jindan Ascension, or if the Nine Stars Alignment reappears, then you will be directly connected to the world by the light path, at least you don't have to be trapped in this place.

There was an additional bronze temple in the ancestral land of the feather people on the moon, and as time passed, the temple gradually covered with thick dust.

Ten thousand years of dead silence.

The four stages of the world.

A bad world on the verge of extinction can only slowly move towards extinction, and the upper limit of everyone will be sealed.

The luckiest thing is to escape and leave this place forever.

There is no sun and moon in the mountains, and it has been a thousand years in the world.

The world is changing at a rapid pace.

With the emergence of Tianshu, human beings have successfully solved various problems, various wonderful minerals have appeared, and the human world has experienced a technological explosion, and high-rise buildings have risen from the ground.

Thick smoke billowing over the city, dark sky, damp streets, flashing neon signs, crisscrossing streets, the same city, magic and reality coexist.

In the middle of the night, the light rain continued, and the signboards of the entertainment venues were still flashing.

Whoosh!

The black-clothed knight walked through the jagged eaves and roofs, and the blood-red skin sheath around his waist flashed away.

Inside the factory, workers sweat profusely, fueling steam engines, and huge machines run to produce goods.

The wide streets, the whistles, the steam locomotives with rivets and iron sheets galloping, and the unbridled laughter of teenagers can be heard from time to time.

In the center of the city, the eight-story Tianshu is running day and night, calculating the Tianji Avenue.

In the ballroom, the dancers are naked, with flower petals on their eyebrows, their eyes fluttering, and the huge colored lights on the top are flickering.

The magnates wore crystal glasses, and the intricate pocket watches made a wonderful sound of blinking.

Smack!

Carved enamel lighter lights a cigarette.

At the moment when light and darkness are handed over, the sword flashes, the head falls to the ground, the dance floor is chaotic, the woman screams, and the chivalrous man floats away, hiding his merit and fame.

"Chase!!" Only then did the bodyguards react.

Chasing on a rainy night, figures flickering, and forces from all sides are intertwined.

Killing machines on rainy nights, knights, steam locomotives, neon, sewage...... Together, they form a strange and harmonious pattern.

Welcome, Steam Rivers and Lakes.
