At this moment, Long Xuan finally realized that there was no need to stick to the rules when refining Gu worms. The materials did not have to be insects; he could incorporate some materials that ordinary people would not dare to think of.
This broadened the potential of the Gu significantly.
Inspired by the cow eye, Long Xuan quickly thought of the eagle eye. The eagle eye also had the ability to magnify objects, and it was even sharper, able to see prey ten kilometers away as if it were close.
If he added the eagle eye to the Gu recipe, it might give him the ability of clairvoyance.
When he wrote the words "eagle eye," the progress on the Gu recipe changed again instead of disappearing, which proved that he succeeded once more.
The next part was the long process of working on the Gu recipe. Every day, Long Xuan would hide at home to work on the Gu recipe, or go to the Jixifang Market to collect the materials listed in the Gu recipe, picking up deals and making crazy amounts of money along the way.
He already saw that the cost of the second Gu worm was probably astronomical.
This brought up a disadvantage of the golden finger.
It's important to note that many Gu recipes use the same material.
So how does the golden finger identify which Gu recipe the remaining recipe written by Long Xuan belongs to?
Therefore, the golden finger's judgment is based on the Gu recipe that requires the most materials.
You should know that the number of materials recorded on each Gu recipe is different; some may be more or less, and some may be as few as nine to tens of thousands.
The quality of the Gu worms in this world is determined by the quality of the spiritual insects, so how strong the ability of the Gu worms can carry is completely determined by the number of spiritual insects.
The strength of the Gu worms depends on the quality, and the same quality depends on the number of materials.
But this is not absolute. Gu worms with more materials do not necessarily mean they are stronger than those with fewer materials, and this situation still happens frequently.
Because the Heavenly Dao's judgment standard for strength is different from that of humans. For example, the lighting technique of the Light Gu worm seems very weak in the eyes of the Heavenly Dao, but is it still weak after being developed by someone?
What's more, Gu worms are also divided into practical and non-practical types, combat and non-combat types.
There are many examples of Gu worms that cost tens of thousands of materials to refine but carry impractical auxiliary abilities and have no combat power.
In ancient times, the spiritual power of heaven and earth was abundant, and spiritual insects were everywhere, so it was possible to study Gu recipes regardless of consumption. The Gu recipes of that period were longer and longer.
It is said that some Gu recipes are entire books, with hundreds of millions of materials, and no Gu-making vessel can hold them.
When making Gu, one can only use mountains, rivers, basins, or even the world as a vessel.
When the Gu is made, the world will suddenly change, and strange phenomena will descend, causing extremely terrifying scenes.
The Gu worms in these long Gu recipes also have the power to destroy the world and can even carry the power of space and time.
So, if the golden finger is determined by the maximum number of materials, then the Gu recipe created by Long Xuan can have as many materials as he wants, even if the progress of the Gu recipe has seven decimal places.
But humans generally have a mentality of greed.
Even though they know that a long Gu recipe will consume a lot of time and materials, and the Gu worms refined may not be stronger than those with fewer materials.
But in order to pursue perfection, Long Xuan still bit the bullet and persisted.
At this time, he dared not imagine how many spirit stones this seemingly long Gu recipe would cost him.
Fortunately, the reputation of the Resilient Roach Gu he researched had spread.
When Li Erniu was fighting his mortal enemy, he successfully killed his enemy by exchanging injuries for injuries.
At the same time, his enemy pierced his heart with a fatal blow, but Li Erniu did not die.
This incident caused a sensation, and Resilient Roach Gu became completely popular because of this battle.
Resilient Roach Gu became well-known overnight, and since then, Resilient Roach Gu has completely opened up sales, and people come to trade every day.
If Long Xuan was not afraid that others would find out that his success rate in refining Gu was 100%, he would really want to sell it every day regardless of the number.
By selling Resilient Roach Gu, and occasionally picking up deals at street stalls and gambling stone shops, he made a lot of money, which could support the consumption of his second Gu recipe.
Of course, he completed all kinds of transactions by disguising himself, covering his face, and disguising himself as different identities each time.
Although there is a rule in the market that prohibits killing people for treasures, as long as you don't carry heavy treasures, you won't be targeted, but he is cautious by nature and decided to play it safe.
Time passed, and two years had passed without him noticing. He was still the same, in the early stage of gathering spirits, his cultivation had not increased much, and he was completely numb.
Fortunately, he could live forever, and if his talent was not enough, he would make up for it with time.
Long Xuan believed that he would stand on the top of the world sooner or later, and he was very optimistic about his future.
Speaking of longevity, although his cultivation talent was surprisingly poor, he was a genius in practicing health-preserving exercises.
In just two years, he broke through two levels and cultivated to the twelfth level of the "Eternal Life Sutra," and his lifespan soared by two hundred years.
Therefore, even though two years had passed, he still looked like a boy under eighteen years old, so young that it was astonishing.
With the increase in total lifespan, the time for maturity would naturally be extended proportionally, which he found distressing.
As for the research on the new Gu recipe, since he did not spend time on deducing the "Eternal Life Sutra," he succeeded after two years of hard work.
Although he had already prepared himself mentally for the possibility of a lot of Gu recipe materials, he was still shocked when the Gu recipe with more than three thousand ingredients came out.
You should know that other scattered Gu-making methods only require dozens of materials, and some only use a few hundred. The number of materials he had was simply too many to count.
There are thousands of materials in the Gu recipe, and many are expensive high-quality spiritual insects. The cost of refining the Gu alone is an astronomical figure.
A rough estimate is that it costs millions of spiritual stones, which is ridiculously expensive.
He had frequently visited the market over the years, used his golden finger to find countless treasures in the market, and sold countless Resilient Roach Gu. He finally gathered the spiritual stones required for a set of materials by piecing them together.
However, this time, refining the Gu has basically spent all his wealth, and he returned to the time before liberation overnight.
Long Xuan was in great pain.
It cost such a huge amount of money and took such a long time. If he didn't gain the illusion ability after the Gu was made, his mentality would collapse.
