"This thing is really complicated."

Ye Suifeng calculated the time and found that the time he spent in seclusion this time was actually longer than the last time he spent studying Taoist magic.

It is worthy of being called an ancient Taoist weapon by the Immortal Emperor Shenwu.

It is no wonder that the people of Tianji Valley spent dozens of generations and tens of thousands of years of time and energy to deduce the refining methods of the first nine levels before finally completing it.

"Fortunately, this effort has paid off."

Ye Suifeng looked at the broken little tower in front of him.

He finally figured out the refining methods from the tenth to the thirteenth levels.

The amount of immortal stones required has also been determined.

Pretty much as expected.

The tenth level requires a million immortal stones to be successfully refined. It can produce an original spiritual liquid that is more powerful than the ninth level's Heavenly Liquid.

Ye Suifeng called it the original essence of the Tao.

The Great Way is the way of all the heavens and worlds, and it is superior to the way of heaven of all the worlds except the fairy world.

This kind of pure spiritual liquid is the best tonic for ordinary small worlds.

No wonder the Immortal Emperor Shenwu said that only when the Tower of Origin of All Things is above the tenth floor can it have a very obvious effect on the advancement of the world.

Then, the eleventh level directly increased to 100 million immortal stones before it could be refined.

The original liquid produced on the eleventh layer is even more terrifying.

It is a kind of mother energy that was born from the earth when the world began.

Ye Suifeng called it the Xuanhuang Essence.

If we say that the original essence of the Great Dao is the soul of the world, it is a great tonic for the spirit of the Heavenly Dao.

The Xuanhuang primordial fluid nourishes the body of the world.

It can elevate the entire earth and fundamentally change all living things in the world, making them more spiritual and more enlightened.

Simply put, it is to enhance the source of talent.

The original liquid produced on the twelfth layer is the truly rare and ultimate treasure.

First of all, in order to refine it, one needs to invest hundreds of billions of immortal stones.

You know, the Divine Martial Immortal Emperor, one of the most powerful beings in the Immortal World, felt extremely distressed when he took out tens of millions of immortal stones.

Hundreds of billions, this level.

I'm afraid that only those very ancient superpowers could possibly possess such wealth.

The original liquid produced by the twelve layers is the breath produced from the chaos when the heaven and the earth were first separated.

Ye Suifeng called it Hongmeng Essence.

This is a true essence of creation. It can easily change the fate of a living being and make his destiny reach an incredible level.

It can also enlighten the world and make the path to its advancement smoother.

From the tenth level to the thirteenth level, the most powerful essences produced are all heaven-defying treasures for the world.

If we regard the world as a monk.

The original essence of the Great Dao is equivalent to promoting cultivation.

Xuanhuang original liquid is equivalent to strengthening the body.

The Hongmeng original liquid is equivalent to a kind of enlightenment.

"Heiwazi, I am really worried about you."

Ye Suifeng looked at the black egg on the table and sighed.

Then he removed the surrounding formations.

After being secluded for several months, he felt that the air outside was really fresh.

"Um?"

Ye Suifeng let out a light "hmm".

I haven't noticed it for a few months, but the surrounding environment has changed a lot.

The wood element is flourishing and full of fairy spirit. Most importantly, it seems as if the world has become spiritual and is no longer the lifeless place it once was.

It seems that the spirit of heaven has gradually matured.

"Master."

When Gu Youlan saw Ye Suifeng, she hurried over. She had been waiting outside these days.

"Just get something to eat." Ye Suifeng said.

He has always been unwilling to give up his appetite.

"Why."

Gu Youlan responded, turned and left.

After a while, Ye Suifeng was satisfied with his meal and wine.

Then, he took out a nine-story origin tower from the small world.

"Let's take a look at the final effect of the twelve-story tower."

Ye Suifeng did not hesitate and directly took out a large pile of fairy stones.

The light coming from the fairyland made the entire island in the middle of the lake much brighter.

Afterwards, he cast a series of spells, and pieces of immortal stones flew to the top of the Origin Tower and sank into it in the blink of an eye.

This is a very complex process.

Each fairy stone must be engraved with extremely complex and profound formations, and it also needs to be connected to other fairy stones.

Only by building a very profound knowledge of the art of formations and spending a lot of energy, can one complete a piece.

Even Ye Suifeng was extremely cautious.

Only a few thousand formations can be engraved at one time.

The refining process lasted for two or three hours before he successfully refined the tenth-floor Origin Tower.

A mysterious aura slowly emanated from the tower.

The powerful rhythm of the Great Dao has begun to gradually condense in the tenth layer.

Similar to before, it should take a year to condense a drop of avenue liquid.

However, after it was successfully refined, the production speed of the first nine layers of raw liquid increased significantly.

Ye Suifeng roughly calculated and found that all of them had increased by about a hundred times!

Before the tenth layer, each additional layer would increase the original liquid tenfold.

Unexpectedly, after the tenth level, the speed increased by a hundred times!

"interesting."

Ye Suifeng was amazed.

He checked the status of the Origin Tower and found nothing wrong.

Afterwards, he took action again to refine the eleventh level.

This time, with experience, I was not as careful as before.

He directly split his soul into hundreds of clones, which could refine millions of immortal stones at one time.

Moreover, he planned to complete the remaining two layers this time.

A few more hours passed.

A twelve-story Origin Tower quietly suspended in front of Ye Suifeng.

"It's finally over."

Ye Suifeng exhaled and looked over.

At the topmost level, there was a faint purple aura shrouding the air. That was the ultimate power of creation, the Hongmeng Essence.

The eleventh layer is a thick dark yellow mist, which is exactly the Xuanhuang Original Liquid.

With the completion of the twelfth layer, its solidification speed also increased by a hundred times!

And on the tenth layer, a transparent liquid has appeared.

The essence of the avenue.

As for before the tenth floor, the production speed has increased by a full million times!

In other words, the spiritual fluid output of a twelve-story Origin Tower is equivalent to that of a million nine-story Origin Towers.

It's just...horrible.

If all the current origin towers were refined to the twelfth level.

Then, the whole world will be able to achieve the same prosperity as in the Yunxiao Holy Land!

Every month, there is spiritual rain, which moistens the world.

It is impossible to imagine what this world and all the living things in it will reach in the future!

Ye Suifeng looked at the Origin Tower, then stretched out his hand and drew out the condensed avenue liquid.

The breath of the origin of the Great Dao immediately surged out and rushed towards the sky.

At the same time.

Heidan has been silent for more than half a year.

"Crack!"

A crack appeared!
