The master and apprentice then stopped in one place. In front of a special area where space is crisscrossed by chaos.

"Master, the Xuanhuang spirit creature bred here should be the top in the entire mountain and sea beast world."

"Space, chaos, with a hint of the power of the stars."

"This thing is suitable for refining a Xuanhuang Lingbao battleship, and the speed should be very fast."

Xu Feng stretched out a hand and gently placed it in the special world that was giving birth to spiritual objects.

"It's a pity that the Xuanhuang Supreme Treasure level spiritual object was not bred."

"As long as the master insists on continuously investing in it in the future, it will inevitably evolve into a more top-level spiritual object."

"It's only a matter of time before something even higher."

From Shengyu's point of view, not to mention the Sutra of Mountains and Seas in Xu Feng's mind, the gate of reincarnation above the world of mountains and seas and beasts alone is at least a Hongmeng treasure level.

"That's right." Xu Feng nodded slightly.

In the Origin Realm of the Human Race, after coming out of the world of mountains and seas and divine beasts, Xu Feng preached and solved his doubts in a preaching world for the Terran saint-level god-level alchemists.

Over the years, with Xu Feng's efforts, there have been tens of thousands of god-level alchemists in the human race, and there are countless saint-level alchemists.

But Xu Feng was still not satisfied with this, the Dan Dao Xuanhuang Realm he had opened up before had not yet been systematic.

Now through the Dan Dao Xuanhuang Sutra received in the Golden Lotus Inheritance Space of the Eight Rank Avenue, Xu Feng has formed a stable system for his Dan Dao Xuanhuang Realm.

In the huge preaching dojo, this group of top alchemists of the human race all had the intention of pilgrimage.

All the alchemists were looking forward to the Terran, the only Xuanhuang alchemist, to preach and solve his doubts.

In the past tens of thousands of years, although there is the Dan Dao Sutra made up by Xu Feng, there will still be many doubts in my heart.

Some rely on time to settle naturally, while some doubts are like demons in their hearts to disturb their state of mind.

Xu Feng appeared on the throne of the preaching world.

In an instant, all the Terran alchemists in the preaching world could see Xu Feng's figure in the sky.

"Meet Master Xu!!"

All the saint-level god-level alchemists stood up and saluted.

"Get up, I haven't preached for tens of thousands of years, I guess you're all suffocated."

"Let Xiao Hei convey the doubts about Dan Dao, and this time it will all be solved for you."

In an instant, all the human alchemists saluted again and thanked them.

In the sky, a huge light curtain appeared next to Xu Feng's phantom.

The light curtain contained all the doubts of a saint-level god-level alchemist, and it was increasing at an extremely fast speed.

Xu Feng looked at the confusion on these Dan Daos, just like the difficulties encountered by a child in adding or subtracting within a hundred.

A day later, Xiao Hei had collected all the doubts and puzzles of all the saint-level god-level alchemists over the years.

Xu Feng looked at the light curtain, and the rhythm of the Dan Dao behind him surged.

A large pen condensed by Dan Dao appeared in the sky, and was then held by an invisible hand.

Began to make paper from heaven and compose the Dan Dao Holy Chapter.

And as the pen of the Dan Dao was written, there was less and less confusion in the light curtain.

I've been writing for more than a month, and the light curtain that records the confusion is now blank.

"This chapter is a million words, giving you ten years to understand."

"After that, if there is any confusion, I will bring it up to Xiao Hei again." Xu Feng said leisurely.

As a Xuanhuang Dan Master, the preaching is still as usual, one by one, and the compulsion is too low.

Xu Feng directly used these doubts as the title to write a Dan Dao Sutra.

This contains almost all the doubts and solutions of the saint-level god-level realm on the Dan Dao.

Countless alchemists in the preaching world all looked at the great sutra in the sky obsessively, and the brilliant colors in their eyes became brighter and brighter.

The great scripture of millions of words in the sky, every word exudes the rhythm of Dandao.

Comprehending any of these words can support a mortal from a mortal-level alchemist to a saint-level.

When all the words were connected, the Terran alchemist seemed to see himself, growing all the way from the original mortal-level alchemy, and finally becoming the pinnacle of the god-level alchemist.

And in the end, he finally took that last step and became a Xuanhuang alchemist.

The avenue is eternal, ten years have passed, and when Xu Feng's voice sounded, all the alchemists only felt that they had slept a very heavy nap.

"Master Xu, 10 years is not enough, let's watch it for a while longer~"

The god-level alchemist led pleaded.

"In 10,000 years, I will ask Xiao Hei to speed up the time here, and when the time is up, I will come back to preach for you."

Xu Feng shook his head as he spoke, thinking that ten years was enough.

Leaving the world of human preaching, Xu Feng came to a fairy city famous for its food.

In a restaurant, the shopkeeper respectfully brought Xu Feng into the secret realm of the private room specially prepared for him.

At this time, Niu Yibo, who was planting in the secret territory of the Niu family not far from the central immortal city, was suddenly brought to Xu Feng by an invisible force.

"It's not interesting to taste food alone, come and come together." Xu Feng said with a smile.

"Brother Xu!!"

Niu Yibo was very surprised to see Xu Feng.

"Over the years, I heard that your Niu family has developed well, and there have been many powerful second-realm powerhouses." Xu Feng said with a smile and motioned for Niu Yibo to take a seat.

"Thanks to the gourd vines of the Xuanhuang Realm that Brother Xu gave me."

"The innate treasure level gourd that has been planted is very powerful when it is refined into an innate treasure."

"My juniors are also angry, and their reputation has been raised a little." Niu Yibo said with a smile.

He opened a jar of wine and poured it for Xu Feng with a familiar car.

"In fact, there are also many powerful juniors in Brother Xu's family, and those in my family often tell me."

"But no matter how powerful they are, they are not outstanding compared to Brother Xu, the co-leader of the human race."

"Really?"

Hearing this, Xu Feng was stunned for a moment, and then thought about it.

The juniors in the Xu family performed well.

The two chatted for a long time in the top restaurant of the Terrans.

At this moment, Xiao Hei's voice suddenly sounded in Xu Feng's heart.

"Master, the Heavenly Machinery Clan has come to visit, and they are already waiting outside the Yuchuan River domain."

"I see."

After Xu Feng replied, he turned his head to look at Niu Yibo.

"I still have some things here, and I'll talk about them later when I have time."

"Brother Xu, your business is important, get busy first." Niu Yibo hurriedly said.

Outside the Yuchuan River Domain, a Celestial Weapon Clan warship floated in the Great Chaos Sea.

A powerhouse of the Four Realms Heavenly Weapon Clan was quietly waiting for Xu Feng.

Xu Feng walked out of the spatial crack, feeling the breath of the four realms, and his heart was even more doubtful.

"Meet the seniors."

"You're welcome~"

The powerhouse of the Four Realms Heavenly Weapon Clan raised his hand slightly, and the surrounding area changed instantly.

Xu Feng appeared in a mechanical temple.

"I came to visit this time, and I want to ask Master Xu Dan to refine some special Xuanhuang Dan."

"Its material can only be presented in the Celestial Machine." (End of chapter)
