Fang Yu moved forward carefully.
Along the way, he was careful and did not interact with anyone.
In order to avoid trouble, Fang Yu tried his best to avoid all the crowds.
In this way, the speed of his progress was much slower.
Finally, on the fourth day, Fang Yu stood in front of a majestic city.
At this time, the city was desolate. On the streets, there were not many people.
It looked quite desolate.
Compared to the Distant Star City, this place was really too desolate.
After asking around, Fang Yu found out.
It turned out that in this Taowu State, not only Qiu Ri City, but also the other dozens of cities were basically formed by sects.
The local residents were almost all disciples of the sects.
At this time, it was the day of the sects' meeting. Many experts and disciples of the sects were all gathered in the Distant Star City.
Therefore, this place was relatively desolate.
There were only a few people on the street.
Fang Yu did not stay for long. He found the direction of Purple Spirit Mountain and sped up again.
Finally, on the second day, a continuous mountain range appeared in front of him.
The mountain range was so high that the top could not be seen. It stretched for hundreds of miles.
From afar, it was densely covered with branches and forests. There were few traces of people.
Looking from afar, the scenery here was not bad.
However, the locals knew that there were many dangers hidden under this spectacular scenery.
In the past hundred years, countless drunken and murderous butchers had been hiding in this dense forest in Taowei Province.
Fang Yu calmed down.
This Purple Spirit Mountain was really big. He did not know where the Pill Saint would be.
However, since he had already come here, there was no reason to retreat.
After channeling all the spiritual energy in his Dantian Qi Sea to his whole body, Fang Yu released all of his perception and scanned the surroundings.
After scanning the surroundings, he did not feel any strong aura.
Other than the aura of spirit beasts that flashed by, there was no other abnormality.
Fang Yu then stepped into the dense mountain forest.
The mountain forest covered a large area. However, there was only one road up.
Perhaps because no one had set foot on it for many years, this road was almost covered with dense branches.
The journey forward was not easy.
A few hours later, Fang Yu followed the downward terrain and walked into a canyon.
In this canyon, what came into view was also a sea of green.
A few spirit beasts were entrenched in front of them.
These spirit beasts were very powerful. Just by looking at their physical bodies, they were all at the peak of the Emperor Realm.
Furthermore, there were six of them!
Fang Yu couldn't help but become cautious.
At this time, he did not dare to be careless.
At the entrance of the Wind Valley in the Frost Smoke Mountain Range, Fang Yu had personally witnessed a few peak Martial King experts dealing with a Spirit Beast of this rank.
Just one of them was enough to injure many people.
What was truly frightening about this spirit beast was not its strength, but its physical body!
That barbaric charge was enough to tear apart many people below the Martial Royal Realm.
If it wasn't for Fang Yu's dragon armor protecting him, he would have been crushed into powder.
Carefully avoiding the group of spirit beasts, Fang Yu went around the canyon.
This was already the largest area within the range of his perception.
The space behind was unknown.
However, just as Fang Yu was about to continue releasing his perception to investigate the area, Fang Yu suddenly stopped.
Suddenly, there was a stuffy heat around him.
This stuffy heat came suddenly and left just as quickly.
However, it was still clearly captured by Fang Yu.
Earth Vein Fire!
Fang Yu was shocked, and a strange thought instantly surged into his mind.
This feeling just now was undoubtedly the Earth Vein Fire!
The Earth Vein Fire was as its name implied.
This fire was not an open fire, it did not belong to man, nor did it belong to the heavens.
It was similar to underground spring water, coming from the earth veins.
Different from volcanoes, the temperature of the Earth Vein Fire was not high.
However, it burned for a long time.
Usually, an Earth Vein Fire could burn for thousands of years.
Moreover, this fire was very pure.
There seemed to be no trace of it in the entire Jiaozhou.
As for the continent where the Tianji Institute was located, it was even more unheard of.
Unfortunately, this Earth Vein Fire did not have much effect on ordinary cultivators.
At most, it had an auxiliary effect on tempering the body.
However, this Earth Vein Fire was a great opportunity for alchemists.
When he was in the Azure Dragon Academy, Yao Chi once said that the best elixirs in the world were none other than supreme grade elixirs.
And the refining of supreme grade elixirs was none other than a high-grade alchemy furnace.
Usually, the conditions for supreme grade elixirs were high-grade spiritual flowers and spiritual herbs, as well as a high-grade alchemy furnace.
Neither of these two things could be missing.
However, with the Earth Vein Fire, refining elixirs would be much easier.
Even if it was not a high-grade spiritual flower or spiritual herb, after being tempered by the temperature of the Earth Vein Fire, there was a chance to condense into a supreme grade elixir.
As long as the alchemist put his mind to it, it might even surpass the grade of a supreme grade elixir.
The Earth Vein Fire was truly a rare sight!
Fang Yu had never heard of it in history!
The reason why he could be certain with just a slight feeling was that there was a faint pill fragrance accompanying this warm fire.
This pill fragrance was rich at first, but after a while, it dimmed a lot.
However, after dimming, it did not dissipate for a long time and was soul-stirring.
Just the pill fragrance alone was enough to intoxicate people.
Fang Yu was very familiar with this pill fragrance.
Supreme grade elixirs!
He had refined this supreme grade elixir not long ago.
However, that elixir took him a lot of effort.
If it was on the Earth Vein Fire, it would be twice the result with half the effort.
Following the pill fragrance, Fang Yu gradually moved forward.
He was sure that this supreme grade elixir was definitely made by an expert.
It was most likely the legendary Alchemy Saint.
One had to know that the supplementary ingredient for supreme grade elixirs, the Purple Daylily, was not easy to find.
Not everyone was as lucky as Fang Yu to have a chance encounter.
Without the Purple Daylily, even with the Earth Vein Fire, it was completely impossible to refine a supreme grade elixir.
Therefore, there was only one possibility.
The alchemist was the Alchemy Saint.
The Alchemy Saint's attainments in alchemy were much higher than Fang Yu's.
There was even a saying that any one of the Alchemy Saint's elixirs had the effect of reviving the dead.
It was no wonder that the Alchemy Saint would appear in this Purple Spirit Mountain.
The Earth Vein Fire was not something that everyone could find.
However, once it appeared, it would definitely attract many alchemists.
For a sensitive expert like the Alchemy Saint, it was naturally not difficult to find the Earth Vein Fire here.
Previously, Fang Yu had thought that the Alchemy Saint was tired of the mortal world and hid in this dangerous Purple Spirit Mountain.
Now, it was clear that it was the Earth Vein Fire that had attracted the Alchemy Saint!
Perhaps it was not only the Alchemy Saint. Once the news of the Earth Vein Fire here spread, it would definitely attract many alchemists.
By then, this Purple Spirit Mountain would be lively …
