Since entering the Vulcan Mountain, Kong Yu has been using the God Killing Spear, in addition to not wanting to expose his hole cards too much, but also in order to hone himself, using the water attribute God Killing Gun in the Fire God Mountain, which is naturally very powerful for the test of Kong Yu's soul power, and now in the face of this fire crow in the sky, Kong Yu also has to summon the Twelve Heavenly Demon Flags, because in this Fire God Mountain, only this artifact can exert all its power and solve the difficulties in front of him.

Kong Yu put away the Killing God Spear, and stood in the Great Array of the Twelve Heavenly Gods composed of the Twelve Heavenly Demon Flags, the soul power of the Fire Attribute Origin Jin Dan in the Sea of Knowledge and the Fire Attribute Soul Power of the Five Elements Soul Fire in the Dantian were all infused into the Twelve Heavenly Demon Divine Flags, and suddenly the Twelve Heavenly Demon Divine Flags were black light flashing, and a venerable ancestor of the Wu clan appeared on this huge flag, and let out an excited roar, and then with Kong Yu's mind, he began to hunt, and the Venerable Weapon Spirit was gulped, and the flame crows in the sky were absorbed by them, and then they condensed into flame crystals one by one, and then they all appeared by Kong Yu's side.

The flame crows in the sky are constantly decreasing under the attack of these twelve machine spirits, and with the protection of the Twelve Divine Evil Arrays of the Twelve Heavens, all the flame crows are unable to break through this protection to attack Kong Yu, all Kong Yu only needs to stand in the Twelve Heavenly Demon Divine Flags, and be responsible for putting away the flame crystals that fall like raindrops, of course, in addition, Kong Yu also needs to provide enough soul power for the Twelve Heavenly Demon Divine Flags to ensure the normal operation of the Twelve Heavenly Demon Divine Flags.

With the appearance of the Twelve Heavenly Demon Divine Flags, Kong Yu's crisis was immediately lifted, sitting cross-legged on the ground, running the Yin and Yang Divine Skills, refining the obtained flame crystals, condensing them into soul power, and then transporting them to the Twelve Heavenly Demon Divine Flags, so that the power of the Twelve Heavenly Demon Divine Flags can be maintained all the time, the number of flame crows does not know how many, in the short period of time when the Twelve Heavenly Demon Divine Flags appeared, Kong Yu got tens of thousands of flame crystals, so now even if it absorbs and refines some, it doesn't matter.

The roar of the demon god echoed in the Fire God Mountain, and the flame crows in the sky still did not flinch under the attack of the twelve heavenly demon god flags, croaking and frantically attacking the weapon spirits on the twelve heavenly demon god flags, but they were all devoured by the twelve weapon spirits. Because these twelve heavenly demon flags are fire attributes, they are naturally like fish in water on this fire god mountain, and the power that can be emitted is naturally the greatest, and each instrument spirit is roaring excitedly, constantly devouring the flame crows in the sky.

The other ancestors of the Wu clan standing on the top of the Fire God Mountain were also extremely surprised when they saw the power of the Twelve Heavenly Demon Divine Flags summoned by Kong Yu, what kind of eyesight they had, they could naturally see that the spirit of Kong Yu's artifact could evolve, and what surprised them was that the evolution space of Kong Yu's artifact was huge, and it was possible to evolve to the point of creating an artifact, and it also contained the breath of the fire god Zhu Rong, so everyone looked at the fire god Zhu Rong, and at this time the fire god Zhu Rong was proud。

In the previous time, the ancestors of the Wu clan only paid attention to Kong Yu's cultivation of the Great Yin and Yang Technique, but they didn't care much about other situations, and when they saw Kong Yu summon the Twelve Heavenly Demon Divine Flags, they were all very surprised, which reminded them of Kong Yu's time in the Battle of the Holy Son, why didn't they care much about the artifacts they rewarded, it turned out that they actually had such an artifact that could evolve, and the ancestors of the Wu Clan also saw that Kong Yu had a total of five artifacts, with five element attributes, but only these twelve Heavenly Demon Divine Flags were the most powerful, and saw Zhu Rong's proud look, naturally, let them know that these twelve heavenly demon flags were made by Zhu Rong.

"I didn't expect you to be willing to pay for it, but if you are willing to do it, I won't be stingy. Looking at Zhu Rong with a smug face, Gonggong despised him fiercely and said, and then grabbed Kong Yu Yao on the first layer of Huoshen Mountain, and suddenly The god-killing spear in the trick flew out and went straight to the top of the Huoshen Mountain, which made Kong Yu, who was absorbing and refining flame crystals and providing soul power for the Twelve Heavenly Demon Flags, startled, but looking at the direction in which the god-killing spear flew, Kong Yu did not resist, and let the god-killing spear fly away, but he was muttering in his heart that this fire god Zhu Rong was crazy again, and he actually took his god-killing spear again, but he didn't know that this time it was the water god who worked together.

The god-killing spear suddenly appeared in Gonggong's hand, and then Gonggong looked at the god-killing spear, nodded incessantly, and then stepped aside to refine-lein. Gonggong is also the same as Zhu Rong, and he integrated his natal essence blood into a drop to the god-killing spear, which changed the essence of the god-killing spear, making this god-killing spear more powerful in the future, and the space for evolution has become larger, and there is a basis for evolving to create artifacts.

Seeing Gonggong's approach, Houtu, Jumang and Bei Shu also smiled, and then grabbed Kong Yu, and immediately summoned the Donghuang Bell, Kyushu Ding and the Six Reincarnation Heavenly Disks from Kong Yu's body. Bei harvested and refined the Donghuang Bell, Jumang refined the Kyushu Ding, and Houtu was responsible for refining the six reincarnation heavenly disks, and these three artifacts were also added to their natal essence blood, so that the essence of these three artifacts has undergone a huge evolution, and it is also possible to evolve to a creation artifact.

Kong Yu, who was sitting in the Twelve Heavenly Demon Divine Flags, couldn't help frowning when he saw his artifacts flying away one by one, although he knew that Zhu Rong would not want these artifacts of his own, this Huoshen Mountain itself was the most powerful magic weapon, and Zhu Rong, who had such a magic weapon, naturally would not covet these artifacts of Kong Yu, but Kong Yu didn't understand what Zhu Rong was doing, and what was going crazy with the good end.

However, at this time, Kong Yu had no intention of paying attention to these, the spirit of the Twelve Heavenly Demon Divine Flags was exerting their might, constantly devouring the surrounding flame crows, and these flame crows were not afraid of death and continued to attack the Twelve Heavenly Demon Divine Flags, even if they lost countless flame crows, they did not flinch, and they were still attacking fiercely.
