Long Xuan took a deep breath, took out all the materials, and then put them one by one into a large cauldron.
The number of spirit insects was too large, and the original Gu pot could not hold them at all. Now he had to use the large cauldron.
After putting all the spirit insects into the cauldron and covering it with the lid, he began to observe the progress.
If he did not see any progress, it meant that the Gu could not be made. Long Xuan took out all the spirit insects, changed the order, and tried again.
After repeating this step thirty-seven times, the progress [0%] finally appeared in the large cauldron.
At the same time, all the spirit insects in the cauldron instantly quieted down.
The eye that exuded evil spirits was very strange. All the spirit insects that were stared at by it would be fixed in place, with dull eyes and motionless.
It was like being pulled into a fantasy world by an illusion. The soul was pulled into the fantasy world, and the body outside could only be eaten by the evil insects bit by bit.
When the progress appeared, Long Xuan breathed a sigh of relief. Finally, he did not work too long.
The success rate of all Gu recipes is different. Some may succeed after two times of refining, while others may fail after ten thousand times of refining.
He was really afraid that this was a Gu recipe with a very low success rate. It would be difficult to deal with so many spiritual insects.
The next step was to wait patiently. Long Xuan was very curious about how powerful the illusion of this expensive pupil Gu would be. The feeling of opening a blind box made him nervous and excited.
The waiting time always felt long. Long Xuan would check the progress of the big cauldron from time to time, and he was very anxious.
Perhaps the lower the quality of the Gu, the faster it would succeed, and the higher the quality of the Gu, the slower it would succeed.
This Gu actually made him wait for 9981 days, which felt like a year.
Because there was a progress reminder, he waited by the side early on the day of the success. When the progress reached 100%, he was shocked and immediately opened the lid of the cauldron. He saw an evil pupil Gu lying in the center of the cauldron, staring at him with extremely strange eyes.
Long Xuan couldn't wait and immediately dripped blood to complete the blood contract with it.
Have you ever seen a pig run before eating pork? Pupil Gu is a kind of internal Gu. If it is small in size, it will parasitize in the eyes, and if it is large in size, it will parasitize in the center of the eyebrows.
The Long family has a unique Gu recipe called the Evil Dragon Emperor Eye. Old Long even made one himself, so he has some knowledge of how to use Pupil Gu.
This Pupil Gu is a little bigger, so Long Xuan put it on his forehead.
Pupil Gu lay on his forehead for a moment, then instinctively broke through the skin and drilled into the center of the eyebrows.
After it drilled into the center of the eyebrows, the skin quickly merged without any gaps. From a distance, you can't see the wound at all, let alone the evil eye buried inside. It is very concealed.
At the same time, after Long Xuan felt a sharp pain in his eyebrows, his mental power was frantically drawn to the center of the eyebrows and was sucked by the pupil Gu.
After the pupil Gu was full and satisfied, it gave its ability to Long Xuan. At this point, the man and the Gu completed a symbiotic relationship, and they prospered together and suffered together.
Not everyone is qualified to refine the pupil Gu. It has extremely high requirements for the Gu cultivator's mental power. Those with insufficient mental power will be drained of their mental power and die at this step.
Although Long Xuan did not know how strong his mental power was, he had lived two lives, and strong mental power was a common advantage of all time travelers, so he was completely confident in his mental power.
He completed the symbiosis with the pupil Gu without any discomfort, and he could fully afford to provide the pupil Gu with mental power.
At the same time, he also knew what kind of illusion the pupil Gu carried.
This illusion was called the original world, which would perfectly copy the scenery in the real world into an illusion.
Everything in the illusion was exactly the same as reality, and people in the illusion could not see through the illusion by finding differences from the real world.
The absolutely real illusion made it difficult for the person who was in the illusion to find flaws, but he was in the illusion without knowing it.
This was the power of this illusion.
Long Xuan was very excited and could not wait to test the basic ability of the pupil Gu again.
Driven by his thoughts, an eye quickly opened between his eyebrows, emitting a charming evil spirit.
He closed his eyes tightly and tried to use this eye to see the new world.
As he injected his mental power, the world in front of him began to stretch and magnify little by little, which was exactly the ability of a microscope.
Long Xuan was ecstatic. He actually succeeded. He actually studied the ability to magnify tiny objects by tinkering around.
He held his breath, took a deep breath, calmed his beating heart, and began to test the limit of the pupil Gu.
He increased his strength to inject mental power again, and the field of vision in front of him was further enlarged, and soon entered the microscopic level.
At this time, he could already see micron creatures and could already go around the world to look for water bears.
But he was not satisfied with this. He further enlarged, and his field of vision went deeper. He began to see bacteria and viruses floating in the air. At this time, his eyes could already see the nanometer level.
But this was still not enough. He injected mental power frantically, and his field of vision began to enlarge a hundred times, a thousand times...
As his field of vision enlarged, all the images he saw were moving rapidly around from the center, making him a little dizzy.
He didn't know how many times it had been magnified. Now he could see molecules. Going further, he could see atoms and nuclei...
Long Xuan's heart was beating wildly. The reason why he wanted to create this ability was just to prevent others from poisoning him and to catch water bears.
But he didn't expect that this pupil Gu was so powerful that it could magnify the field of vision to the atomic level, and this was not even the limit.
After the spirit insect turned into a Gu worm, its growth would be cleaned and started from zero.
Now this pupil Gu is just an infant with a growth rate of only 0%. It is so powerful when it is an infant. What will it be like when it matures?
Long Xuan dared not imagine it.
The magnification limit of this pupil Gu far exceeded his expectations. Once it reaches full growth, it may explore a world that is even smaller than what he knew in his previous life. He couldn't wait to know what the smaller world is.
Long Xuan began to think about how to use this ability. He couldn't just magnify it without using it.
He just learned not long ago that the ability of the Gu worm can be deeply developed. The Gu worm obviously has only one ability, but the Gu cultivator can make the ability of the Gu worm complicated and diversified with his imagination.
Magnifying an object seems to be just one ability, and it is not very noticeable and has no lethality.
But Long Xuan is confident that his imagination is awesome, and he wants to develop several more abilities based on this ability. Even if it is just an auxiliary ability to magnify an object, he will develop it into a forbidden move.
What can be done by magnifying an object? Long Xuan's imagination began to work frantically.
He first opened the pupil Gu to the extreme and scanned the room. Finally, he found that magnifying the field of vision to the extreme would have a slight perspective effect, but it was limited to very thin and low-density objects.
It is probably impossible to accurately see what kind of insects are in the fossils, and it can only see through a thin layer of the ground, not very deep.
But even at this level, Long Xuan is already very satisfied. Even if it can penetrate deep underground, what does it matter? Without night vision, it is still impossible to see what is underground.
Soon he thought of magnifying other people's elixirs, spiritual insect feed, poisons, and other resources, and cracking their formulas through microscopic analysis.
Then he thought that this ability seemed to be able to move in detail.
The so-called subtle body movements are to dodge the opponent's attack with the smallest amplitude, which is very practical in actual combat, at least it can save a lot of physical strength.
Isn't this practical in combat?
But this is not enough; the lethality of these brain holes is not terrifying enough. He wants to develop forbidden moves, to develop forbidden moves that are not weaker than the light gathering technique...
