After returning, Long Xuan discovered that his clone had already prepared the materials for the Longevity Gu. Without wasting any time, he began refining the Longevity Gu.
Refining the Longevity Gu was relatively simple since it was a low-grade Gu insect, requiring only three hundred sets of materials.
Long Xuan poured all the materials into a large cauldron. When no progress was shown, he poured them out again and repeated the process more than ten times. Finally, when he saw progress appearing above the cauldron, he placed the lid on and left.
Time flew by, and half a month passed quickly. Low-grade Gu insect do not take long to form, and today was the day when the Longevity Gu would be completed.
Based on the progress indicator, Long Xuan approached the cauldron at the precise moment and, without hesitation, lifted the lid and took out the Gu insect inside.
Looking at the plump, fat worm in his hand, Long Xuan pondered for a moment.
Is this the legendary Longevity Gu?
It had no limbs and was plump and white, covered in fat. It was clearly born to be eaten.
After studying it carefully for a long time, Long Xuan found that this little creature had no offensive capabilities whatsoever; it was incredibly weak.
It was likely a one-time-use Gu, with its only ability being to extend someone's lifespan when consumed. Such a pitiful fate.
Long Xuan tossed the fat worm into the mouth of his Sou Gu and waited silently, observing its progress.
After the Sou Gu swallowed the Longevity Gu as per Long Xuan's command, it immediately fell into a deep sleep. Its aura became unstable, suggesting that unknown changes were occurring within its body.
It really worked! Long Xuan's eyes lit up. As long as the Sou Gu showed any change, his plan would be half-successful.
He showed an expectant expression, waiting for the final transformation of the Sou Gu.
He didn't have to wait long. After about two hours, the Sou Gu suddenly woke up, slowly opened its tiny eyes, and then stood up gradually.
At the same time, its progress indicator began to plummet, almost cutting in half.
The increase in total lifespan naturally resulted in a decrease in progress. Seeing this, Long Xuan was overjoyed.
The Sou Gu had undergone a evolution, and its lifespan had almost doubled, proving that his hypothesis was correct. The increase in innate lifespan for Gu insect would lead to a rise in quality. The current Sou Gu was now a mid-grade Gu insect.
Long Xuan's breathing quickened as he immediately began testing the abilities of the mid-grade Sou Gu to see if it could now transport living beings.
In fact, Gu cultivators could understand the abilities of their Gu through their blood contracts. At this moment, Long Xuan already knew that the Sou Gu, after evolving in this manner, had acquired the ability to transport living beings. Moreover, the more times the Sou Gu evolved, the higher the cultivation level of the beings it could transport.
However, Long Xuan was always cautious by nature, and he needed to test the safety of this ability.
To be safe, he first instructed the Sou Gu to transport a random spirit insect to see the results.
The Sou Gu, following Long Xuan’s instructions, casually wrapped around a butterfly that had strayed into Long Xuan's garden and then burrowed into its small pyramid-shaped house.
Not long after, it emerged from the distant Ice and Fire House.
He then looked at the butterfly it had carried. Its eyes revealed a look of fear, but it was unharmed. Long Xuan was ecstatic and immediately began a second test.
Given his cautious nature, one test was never enough. After all, this concerned his life, and he had to be extremely careful.
Next, he performed ten consecutive tests with various spirit insects. When none of the insects showed any signs of danger, he finally attempted to transport a person.
Of course, he wouldn't risk his own life. First, he transported his Fire Clone. After confirming there were no dangers, he sent his other four clones as well.
When all the clones transported safely, he finally felt confident enough to try it himself. He entered the small pyramid house and emerged from the Ice and Fire House, experiencing the sensation of passing through two extremes.

When Long Xuan returned to the pavilion, he continued practicing the Ten Absolute Blade Technique.
When Blade Gu was refined, he needed to study his Ten Absolute Blade Technique. The progress of the Ten Absolute Blade Technique must keep up, and it could no longer be delayed by other matters.
The next part of his life was simple: either practicing the Ten Absolute Blade Technique in his small pavilion or finding his senior sister for dual cultivation.
Sometimes, he would go to the spirit spring to feed the fish and watch the lighthouse jellyfish, or go to the ranch to slaughter a cow and have a beef hot pot. Life was indeed quite comfortable.
Combining work and rest, Long Xuan didn’t feel that practicing the Ten Absolute Blade Technique was hard at all.
Just like that, a year and a half passed by quickly.
Dual cultivation really was the fastest way to improve. Through relentless dual cultivation day and night, he easily advanced to the late stage of the Marrow Cleansing Stage.
As for Long Ziyan, she was even more astonishing. Her talent was much better than his, and the effect of dual cultivation was far superior for her.
Not only did she successfully purify her bloodline to the tenth grade, but she also advanced to the Spiritual Sea Stage, becoming the second casual Spiritual Sea Gu Master in the family after Long Lie. The entire clan celebrated together.
With his wife suddenly becoming a Spiritual Sea Gu Master, Long Xuan felt immense pressure, even feeling unprecedented stress during dual cultivation.
That day, Long Xuan wrote “Ten Absolute Blade Stage Technique” on the cover of a book and signed his name—◎Author Long Xuan—at the bottom right corner.
A faint smile appeared on his face. After spending a year and a half, plus the time in the Western Lands with the Long Clan, it took nearly two years, but he finally managed to complete the Ten Absolute Blade Technique.
The Ten Absolute Blade Technique could break through any weapon in the world. Once the Ten Absolute Blade Technique was unleashed, it was invincible. No one could match him in a contest of weapons.
Having created such an extraordinary saber technique, Long Xuan felt an immense sense of achievement.
He believed that the Blade technique he created was worthy of being called the number one Blade technique in the Gu world. There were countless Blade techniques in the world, but only the Ten Absolute Blade Technique stood supreme.
Long Xuan was filled with pride, looking down on all the saber techniques in the world.
However, to say that the Ten Absolute Blade Technique was absolutely invincible might not be entirely accurate. Not all weapons could be broken one hundred percent of the time, as his realm was still low. It might be possible to truly break through everything in the Gu world, but once he ascended to the Spirit Realm, it might not be able to break through higher-level powers.
His Ten Absolute Blade Technique was still in its initial stage and needed continuous improvement and refinement. The realm of Blade techniques was boundless.
Thinking of this, Long Xuan restrained his arrogance and decided to remain humble. He couldn’t underestimate the myriad methods in the world; no single technique was truly invincible.
“Go, study this Blade technique. Don’t bother with that garbage technique anymore.”
Long Xuan suddenly threw the saber technique in his hand toward Little moon, who was reading not far away.
Yes, in a year and a half, his Blade Gu had already taken form, and it was a rare fifty-thousand-level Blade Gu, using up all the remaining spirit insect species in the Western Lands—extraordinarily powerful.
Among all the Blade Gu in the Long Clan of the Western Lands, his fifty-thousand-level Blade Gu was absolutely peerless, unmatched by any other Blade Gu.
If the people of the Long Clan in the Western Lands knew that Long Xuan had already refined a fifty-thousand-level Blade Gu, they would probably be shocked, their mouths agape.
The success rate of a Blade Gu using tens of thousands of materials was already abysmally low, and no one had dared to challenge such a number of materials for tens of thousands of years. No one had succeeded in refining such a level of Blade Gu for tens of thousands of years.
Long Xuan’s success in refining a fifty-thousand-level Blade Gu was enough to cause quite a stir in the Long Clan of the Western Lands.
However, the Western Land's Long Clan was currently far away from here, and it was impossible for them to know. The area was still besieged by plague zombies and they couldn’t come out.
