Here was a lake as vast as the sea, named Star Fragment Lake. The Star Constellation Immortal Monarch's usual cultivation place was also set at the bottom of Star Fragment Lake.
Going deep into the lake, Fang Yuan discovered a crystal palace. It wasn't large in scale, with only one main hall and two side halls.
The Star Constellation Immortal Monarch's Immortal Gu were preserved in the main hall.
Led by the Star Constellation Land Spirit, Fang Yuan smoothly entered the main hall.
As soon as he entered the main hall, he saw a flying Immortal Gu.
This Immortal Gu resembled a centipede, long and slender like an arm, dull and dark like tungsten iron. It was winding and drifting in the empty space of the main hall, with short cross-shaped marks on its body that occasionally lit up with blue firefly light.
"This is a Rank Six Immortal Gu, Star Mark. It can temporarily add six hundred Star Path Dao Marks to your body, master." The Star Constellation Land Spirit timely introduced.
"Six hundred?" Fang Yuan was taken aback.
The Strength Path Dao Marks on his body were only a little over two hundred. This was thanks to the recent period, using the Eat Strength Immortal Gu, which had increased them by over forty.
This Star Mark Immortal Gu could actually increase over six hundred Star Marks at once, its effect could be described as excellent.
"Over two hundred Dao Marks can enhance power by twenty percent. Six hundred means a sixty percent increase in power. It's a pity they are Star Path Dao Marks, and I am not a Star Path Gu Immortal."
Without a doubt, this Star Mark Immortal Gu was an excellent supporting Immortal Gu!
Even though Fang Yuan was a Strength Path Gu Immortal with Strength Path Dao Marks, once he activated the Star Mark Immortal Gu, his body would be temporarily covered with a layer of Star Path Dao Marks, which would allow him to impersonate a Star Path Gu Immortal!
Apart from Star Mark, there were two other Immortal Gu in the main hall.
One was like a prismatic crystal. The size of a fist, it lay quietly on a table. Completely still.
The other was like a tender white bean sprout, full of life.
Through the introduction of the Star Constellation Land Spirit, Fang Yuan learned that the former Immortal Gu, which looked like colorless crystal, was the Starlight Immortal Gu. The latter, which looked like a bean sprout, was called the Star Sprout Immortal Gu.
Upon hearing this, Fang Yuan was overjoyed.
His luck had arrived!
These two Immortal Gu were even more useful to Fang Yuan than the Star Mark Immortal Gu just now.
Because the Starlight Gu was an essential Gu material for refining the Wisdom Path Star Thought Gu.
Now that he had the Starlight Immortal Gu, he could completely emulate the method of refining the Strength Qi Gu using the Strength Gu, producing Star Thought Gu on a larger scale and more quickly.
With the Starlight Immortal Gu, the troublesome step of purchasing Starlight Gu was saved.
At the same time, using an Immortal Gu as the foundation to refine the Mortal Gu Star Thought Gu was a top-down approach. The failure rate was much lower than previous Gu refining methods. The danger would also greatly decrease. In this way, the losses of the Mao Li would be greatly reduced.
Of course, two problems followed.
The first problem was that to use the Starlight Immortal Gu, Fang Yuan would need to improve the Star Thought Gu recipe.
The second problem was that using the Starlight Immortal Gu would consume Immortal Essence.
However, with the Wisdom Gu and a complete Star Thought Gu recipe, improving the Gu recipe wasn't difficult for Fang Yuan. It was just a matter of time.
As for the second problem, if it were the previous Fang Yuan, it would indeed be an obstacle. But now that Fang Yuan had become the master of the Star Constellation Blessed Land, with its six economic pillars, and even eight profitable ventures in the future, the Immortal Essence Stones he earned were a full four times his current amount! A large number of Immortal Essence Stones gave Fang Yuan sufficient confidence to continuously use the Starlight Immortal Gu while consuming Immortal Essence.
The Starlight Immortal Gu brought great help to the large-scale accumulation of Star Thought Gu. The Star Sprout Immortal Gu was also very useful.
Fang Yuan had once purchased a Mortal Path Killer Move from the Star Constellation Immortal Monarch, named Spring Star Rain.
This move could irrigate vegetation and ensure its vigorous growth. Since obtaining this move, Fang Yuan had been using it intermittently.
The ability to maintain the current scale of the Fox Immortal Blessed Land's aerial grassland was largely due to this Mortal Killer Move.
Frequently using the Spring Star Rain Killer Move consumed a large number of Star Sprout Mortal Gu.
The Star Sprout Mortal Gu were only sold by the Star Constellation Immortal Monarch.
Fang Yuan had once wanted to break free from the Star Constellation Immortal Monarch's control by researching the Gu recipe for the Star Sprout Mortal Gu. However, even with the help of the Wisdom Gu, his Star Path attainment was only ordinary, and he was unable to achieve his wish.
Now that Fang Yuan directly possessed the Star Sprout Immortal Gu, he could use Spring Star Rain as he wished. He could also upgrade the Spring Star Rain Killer Move to the Immortal level, using the Star Sprout Immortal Gu as the core, to play an even greater role in cultivating Star Debris Grass.
However, afterwards, Fang Yuan learned from the Star Constellation Land Spirit that the Star Constellation Immortal Monarch actually had the Immortal Path Killer Move Spring Star Rain in his possession.
In fact, the Mortal Path Killer Move Spring Star Rain sold by the Star Constellation Immortal Monarch was derived from the original version in his hands. The Star Sprout Mortal Gu he sold to the outside world was also refined using the Star Sprout Immortal Gu.
This was the reason it was so difficult for Fang Yuan to reverse-engineer the Gu recipe from the Star Sprout Mortal Gu.
Because the Star Constellation Immortal Monarch's method of refining Gu was completely top-down.
Star Mark, Starlight, and Star Sprout — these three Immortal Gu were all the Immortal Gu left behind in the Blessed Land.
The Star Constellation Immortal Monarch had a total of four Immortal Gu. Unfortunately, the fourth was destroyed in his battle with Song Zi Xing.
Fang Yuan only obtained three.
Even with just these three, Fang Yuan was already very satisfied.
Generally speaking, among the Rank Six Gu Immortals in the entire Five Regions, only a small portion possessed Immortal Gu. The majority still used Mortal Gu and Mortal Killer Moves.
Only the elites among Rank Six cultivators possessed Rank Six Immortal Gu. For example, the Rank Six Gu Immortals of the Ten Great Ancient Sects of Central Continent, or rogue cultivators with fortuitous encounters like the Star Constellation Immortal Monarch.
