Throughout the ages, I don't know how many emperors have asked for immortality at all costs.

There are also countless peerless powerhouses who stand at the top of the cultivation world, even if they are broken bones, they want to live with heaven and earth.

But no one ever succeeded.

At least in the history of mankind in the Starfall Continent, there is no one who can jump out of heaven and earth, not within the five elements, and cross the endless ravine between life and death.

Not even a stellar realm powerhouse.

Luo Chuan had never thought about immortality, and in comparison, if he could, he would probably be more willing to exchange for the opportunity to return to his hometown.

This hometown does not refer to Daliang Jiangzhou, but the blue planet.

What's even more interesting is that the "Book of Eternal Life" that came to Luo Chuan's mind was not some kind of exercise that would prolong people's life or break through the limits of the physical body, but a Dan book!

Perhaps this statement is not accurate enough.

Because from a certain point of view, "The Book of Eternal Life" is still a historical book.

It borrowed the historical development of alchemy, from the day of its birth, to several ups and downs, until today's various methods, showing the rise of the entire human race for Luo Chuan in disguise.

In addition, the Book of Eternal Life is also an illustrated book.

It is similar to the "Thousand Tempers" obtained by Luo Chuan before, except that what is recorded in it is the name, shape, effect, and refining method of various elixirs.

From a first-grade elixir, to a star-level elixir, to a god-level heavenly pill, there is everything, everything.

Of course, at the end of the day, the greatest value of the Book of Eternal Life lies in the various alchemy methods recorded in it.

It's hard to say whether Luo Chuan can master them all, but there is no doubt that this will be his biggest gain from entering the Dan River this time!

It is even more important than the growth of the Flame of Hope, the improvement of the White Flame Burning Technique, and the skyrocketing of one's own cultivation!

Because Luo Chuan saw another new direction for refining pills.

If you want to refine the pill, first refine the fire!

Now the alchemists on the Starfall Continent all know that even if it is the same Dan Fang, the same material, and the same refining method, if the Dan Fire used is different, then the final refining elixir will naturally be different.

For example, using the earth fire in the alchemy room of the Baicao Hall and the Dan fire in the Tianyuan Gate Dan River to refine the same furnace of pills, I dare not say anything else, at least the grades of the two will be essentially different!

If the former is refining the Nine Rank Spirit Pill, then the latter is likely to refine the Star Great Pill!

This is the so-called "explosive pill" in the alchemy world!

But people have never thought that there is actually a difference in the level of fire in the world.

They had never even tried to refine the substance of fire in the Dan furnace in order to extract the more precious essence of fire from it.

Now Luo Chuan knows.

Thanks to the "Book of Eternal Life", but also thanks to the "Spark of the Prairie General Recipe".

He didn't know who created this set of recipes, and he didn't even know if the inheritance he had received came from humans, but this did not prevent him from discovering the value of this "Book of Eternal Life", and the alchemy methods recorded in it were at least several centuries ahead of the current human alchemy world!

What's even more incredible is that the "Book of Eternal Life" also details an alchemy called "making something out of nothing", without the use of Dan fire and Dan furnace, by decomposing and rebuilding the existing elixir, a new elixir can be born!

At this time, Luo Chuan was still in a state of enlightenment, but his hands suddenly moved like dancing butterflies.

I saw Luo Chuan's left hand make a slight move, and a spirit pill jumped up from the Dan River, like a carp that was eager to turn into a dragon, jumped over the high dragon gate, fell into Luo Chuan's palm, and then turned into a piece of dust in an instant.

Immediately afterwards, the second elixir followed, which was easily picked up by Luo Chuan's right hand, and then melted into a drop of residual dew.

The next moment, the dust and the residual dew met in mid-air, and then Luo Chuan clasped his palms in his hands.

This is not a meeting of golden wind and jade dew, and naturally it cannot win countless in the world.

But this is Luo Chuan's first attempt to make alchemy out of nothing, even if it can't be recorded in the history of mankind, it is at least enough to draw a strong stroke in the human alchemy world!

It's a pity that the only thing that can witness all this at this time is the flowing Dan River.

No, maybe it's not just the Nadan River itself.

Because at the same time when Luo Chuan was refining the pill, suddenly a leaf boat came leisurely from afar, riding the turbulent Dantao, and soon came to Luo Chuan's body.

The Dan River is not a real river, so the flat boat is not really a boat, but a long flat box that resembles the shape of a coffin.

It's just that from a distance, it looks like a fishing boat swaying in the wind and waves.

There were people on the boat, but there was no boat in his hand, so no one knew how he stayed in front of Nakcheon just right without being swept away by the Dan River.

It was an old man with a rickety back, wrapped in a long yellow robe, with a big rosacea, and snow-white hair, but his exposed skin showed a certain tightness that did not match the years, although it was not a crane hair, but at least it was very well maintained.

The old man stayed in front of Luo Chuan, then seemed to lean forward with some curiosity, and sniffed quickly, almost touching his nose to Luo Chuan's face, and the hot air he spewed from his nose blew the fire on Luo Chuan's face.

Then, Luo Chuan suddenly opened his eyes.

His enlightenment was interrupted by the other party.

But what is a little strange is that between these four eyes, both sides do not seem to be frightened by each other, but maintain the same posture, just staring at each other in silence.

I don't know how long it took, but the old man finally couldn't help but take the lead in opening his mouth.

"What did you just see?"

"Time. ”

"Can time be seen?"

"As long as you want. ”

The old man nodded, then moved his body back, looking at Luo Chuan with a scrutinizing gaze.

So it was Luo Chuan's turn to ask.

"Who are you?

"It's not. ”

"What are you here for?"

"Just to see you. ”

"Do you know me?"

"I don't know. ”

The old man shook his head like a rattle, but then added, "But I know that little flame in you." ”

Hearing this, Luo Chuan suddenly smiled: "Coincidentally, I know this coffin under your feet." ”

"Oh?" the old man showed a rare look of surprise, and then asked, "Do you want to change it?"

Luo Chuan was slightly stunned, he didn't expect the other party to make such a request, he pondered for a moment, and finally shook his head.

"Sorry, no. ”

When the words fell, the old man suddenly looked extremely disappointed, but fortunately, he did not show the slightest intention of snatching.

Immediately, the old man suddenly spoke: "You can call me Zuo Lao." ”

I don't know why, Luo Chuan suddenly thought of the mysterious man who was sitting on the shore of Hantan fishing for a long sword that day, and blurted out at the moment: "Are you the guardian here?"

Zuo Lao tilted his head and thought about it, and said with a smile: "Sort of, little guy, you haven't told me your name yet." ”

Luo Chuan couldn't help but show a hint of apology, bowed slightly and said, "Luo Chuan." ”

Hearing this, Zuo Lao immediately frowned, and said after a long time: "I haven't heard of it." ”

Luo Chuan was not embarrassed by this, but just smiled: "I'm just a nameless junior, and it's normal that Zuo Lao hasn't heard of it." ”

Zuo Lao shook his head: "The nameless junior can't come to this Danhe, looking at your appearance, you look a little similar to the Dan ghost, could it be that you are his ......"

Luo Chuan couldn't help but cry and laugh a little: "Zuo Lao misunderstood, I have no blood connection with Mr. Dangui. ”

"So, it seems that you are a new Danzi?"

Luo Chuan smiled helplessly: "Zuo Lao doesn't have to guess, I'm not from Tianyuanmen." ”

When the words fell, I saw that Zuo Lao's eyes suddenly became sharp, he stared at the fire bead in Luo Chuan's hand, and secretly frowned: "Then you ......"

Luo Chuan shook his head and said: "This matter is a long story, if Elder Zuo thinks that I am a spy who infiltrated here, you can pass on the sound to Mr. Dangui for verification." ”

Zuo Lao hesitated for a moment, but finally smiled: "Okay, it is said that cultivation is to cultivate chance, and seeing each other is fate, if you don't mind, you can get on my treasure boat to sit, and I will take you to the end of the Dan River to see." ”

Luo Chuan knew very well in his heart that Zuo Lao's proposal was not really hospitable, but had some kind of surveillance.

Originally, according to his original plan, the twelve hours in this Dan River were incomparably precious, and he had to seize every moment to improve his strength, whether it was practicing the White Flame Burning Technique, or strengthening the Flame of Hope, he must not slack off.

It's not a journey, it's a creation.

But a few words in Zuo Lao's words successfully attracted Luo Chuan's attention.

The end of the Dan River.

Of course, there is an end to any one world.

There is an end to the Starfall Continent, there is an end to the Hantan Secret Realm, and there is an end to the Moonshadow Secret Realm.

So naturally, no matter how magnificent and boundless the Dan River looks, there must be an end.

So, at the end of the Dan River, what is it?

Is it Danhai?

Or is it nothingness?

Undoubtedly, Zuo Lao successfully aroused Luo Chuan's curiosity, but if it was just like this, it was not enough for Luo Chuan to set foot on Zuo Lao's boat with a hot head.

So the next moment, Zuo Lao opened his mouth and added: "By the way, many years ago, there was a monk surnamed Yang who left a stone tablet in the Dan River, saying that he would come back to get it in three years, but three years later, I don't know how many three years have passed, and that person has not come back yet, so when you go out this time, bring the stone tablet to the other party." ”

Luo Chuan's heart moved, but his face did not reveal the slightest abnormality, but he just opened his mouth and asked, "Where is the stone tablet?"

"Right at the end of the Dan River. ”

"Do you remember the name of the monk surnamed Yang?"

"Hmm...... It seems to be called a laugh, well, it should be Yang what a laugh. ”

Hearing this, Luo Chuan seemed to be carelessly putting his palm on the Shanhai pot on his waist, moved his left foot back half a step, and asked the last question.

"Why me?"
