Half a month later, the Black Viper and Armored Dragon teams also completed their gu refinement tasks, and the gu eggs were handed over to Wang Xiao.
Wang Xiao also gave them generous rewards, although slightly less than Zhao Jing received.
Next, it was time to officially refine the Blood Shadow Mantis!
This step was the key to the entire gu refinement process, and any interference was strictly forbidden. Wang Xiao had the three generals lead the army away from the Black Pine Forest, leaving him alone to refine the gu.
He chose a location for refining the gu, prepared the gu medicine, set up the gu refinement formation, and so on.
After working for more than a month, and using millions of spirit stones, a huge gu refinement formation was finally set up.
If viewed from the sky, this gu refinement formation had nine formation eyes, each containing a Red Armor Mantis gu egg.
They would be stimulated and hatched by the formation, and then the nine Red Armor Mantises would fight each other to the death. The one that ultimately emerged victorious would evolve into the Blood Shadow Mantis!
The center of the nine formation eyes was the core of the entire gu refinement formation.
This core was crafted from a large number of precious materials. The Dragon Gallstone that Wang Xiao had exchanged for with a Golden Spirit Gu in the Sky City's underground black market, and the Blood Demon Steel that Zhong Li had bid for at the black market auction for millions of spirit stones, were both key to creating this core!
And the most crucial element was the Gu Refinement Stone Slab, which was being protected by the formation's power in the center.
The main component of this Gu Refinement Stone Slab was the essence blood of the ancient super-beast, the 'Sky-Slaying Mantis'!
The Sky-Slaying Mantis was recorded in ancient texts as a magical beast. The Gu Master civilization had developed for thousands of years, and no one had ever actually seen one!
Of course, it was best if no one had seen it!
If even one of these terrifying creatures came to the Gu Master world, it could wipe out all of humanity!
This Gu Refinement Stone Slab was currently the only hope for refining the Blood Shadow Mantis Gu!
When everything was ready, Wang Xiao took out a high-grade spirit stone and inserted it into the formation, activating the entire formation!
High-grade spirit stones were extremely rare. Wang Xiao's small spirit stone mine had only yielded about a dozen of them in total. He usually couldn't bear to use them, but in order to refine the Blood Shadow Mantis, he couldn't worry about that anymore.
As the high-grade spirit stone was inserted, the entire formation was activated and began to operate!
The energy contained within the million-plus low-grade spirit stones was absorbed by the nine formation eyes and supplied to the nine Red Armor Mantis gu eggs.
Under the nourishment of a large amount of spiritual power, the nine gu eggs hatched one after another!
The nine Red Armor Mantises each let out a cry and immediately sensed the Gu Refinement Stone Slab in the center of the formation.
Memories originating from their souls told them that the stone slab was very important to them!
Therefore, the nine Red Armor Mantises, without prior agreement, rushed towards the center of the formation together!
Once they arrived, they couldn't wait to start gnawing on the Gu Refinement Stone Slab.
Unfortunately, the Gu Refinement Stone Slab was harder than diamond, and they couldn't bite it at all.
Soon, these Red Armor Mantises discovered other delicacies!
The specially made gu medicine could stimulate the Red Armor Mantis's killing intent and unleash their full life potential!
The Dragon Gallstone could promote bloodline mutations in the Red Armor Mantis.
The Blood Demon Steel could enhance the Red Armor Mantis's body strength!
Therefore, these Red Armor Mantises immediately began to devour the gu medicine, Dragon Gallstone, and Blood Demon Steel!
After devouring for a while, the nine Red Armor Mantises began to emit a dense blood-colored light, and the most primitive desire for slaughter in their hearts was completely activated!
In an instant, they launched a fierce battle, entering a state of selfless slaughter!
These spirit gu, which had grown up through round after round of slaughter, were extremely powerful, whether in terms of combat experience or killing intent. Therefore, it was not easy for them to determine a winner!
Moreover, even if they were injured, the gu medicine everywhere in the formation would continuously repair their bodies!
Therefore, after three days of fierce fighting, none of the nine Red Armor Mantises had died!
The killing aura accumulated on their bodies became increasingly intense, and even Wang Xiao, who was hiding outside the formation to observe, felt a burst of discomfort!
The Blood Shadow Mantis placed even more emphasis on the condensation of killing aura than any other spirit gu he had refined in the past!
The positioning of this spirit gu was that of a one-hit-kill assassin. If the killing aura was insufficient, even if the spirit gu was refined, its power would be far from satisfactory!
The purpose of the large amount of gu medicine arranged in the formation was to allow the spirit gu to repeatedly kill, condense enough killing intent, and only then could a winner be determined!
Finally, the Dragon Gallstone was eaten, the Blood Demon Steel was also eaten, and the gu medicine was also eaten.
All of these precious materials were integrated into the bodies of the nine Red Armor Mantises, and their physical condition had reached its peak!
At this time, one of the Red Armor Mantises chopped off a piece of the Gu Refinement Stone Slab with a blade. After absorbing the Blood Demon Steel and Dragon Gallstone, even the Gu Refinement Stone Slab could not withstand the Red Armor Mantis's blade.
This Red Armor Mantis immediately bit the stone slab fragment and fled back to the formation eye where it had hatched.
That was the only safe place in the entire formation!
After fleeing back to the formation eye, it immediately began to devour and absorb the substances in the stone slab!
The other Red Armor Mantises were not stupid either. At this time, they had no intention of fighting anymore. Each mantis chopped off a piece of the stone slab and ran back to the formation eye to devour and absorb it.
After another three days, the nine Red Armor Mantises finally absorbed all of their respective stone slabs.
Each Red Armor Mantis was full of fighting spirit. They once again walked out of the formation eye and began a new round of tearing and killing!
They couldn't help but kill, the stone slab energy in the opponent's body was the greatest temptation for them!
Each mantis wanted to devour the other and plunder the energy in its body!
This battle was even more intense than three days ago!
Wang Xiao had to retreat some distance, because the killing aura overflowing from the formation was really alarming, making people very uncomfortable!
Waves of killing aura stirred up the clouds in the sky, causing the sky to be covered with dark clouds, as if some great power was about to undergo tribulation!
Wang Xiao secretly rejoiced in his heart, fortunately there were no too strong creatures in the Pangu Realm, otherwise they would definitely be attracted!
He was happy too early, because this gu refinement still alarmed something!
In the deepest part of the Black Pine Forest, a magical beast that had been sleeping for who knows how many years was awakened. After hesitating for a while, it sensed a huge bloody smell and slowly crawled towards the place where Wang Xiao was refining gu!
