The left half of Zhang Yuan's body was completely covered in black flames, while the right side of his body was a brilliant golden red. The two-colored flames rose at the same time, full of strange aura. And the circle drawn by his hands suddenly turned into two circles of light and floated up, a golden-red Sun God Bird King and a black Hell Annihilation Phoenix Hades flame phantom flashed alternately, and in the two halos condensed behind Zhang Yuan, ancient patterns full of mysterious and strange aura appeared.

The ninety-nine eighty-one twin fire vortex formation in Zhang Yuan's body poured the twin fire elements in the surrounding air into the wooden house almost crazily, and once it entered the range of Zhang Yuan's extreme twin fires, it was immediately condensed, compressed, and filtered, and only after these three processes were passed, the golden red and black of the purest extreme flames left would be integrated into Zhang Yuan's body.

The ninety-nine eighty-one twin fire vortex formations swirled, countless fire energy floated out from the ground and high in the air, and countless fire spiritual power gathered and compressed into Zhang Yuan's body.

At the beginning of his dual-attribute mana cultivation cultivation, Zhang Yuan's cultivation was much slower than that of ordinary cultivators. If it weren't for the fact that in the world of the magma lake and sea in the center of the demon realm, there was such a rich dual fire element for him to absorb, it would be impossible for him to break through again and again in a few years, achieve a three-star and sixth-level realm, and even become a cultivator.

However, now Zhang Yuan's situation has changed drastically, Zhang Yuan, who has all kinds of experience and magic skills in the world of the Shushan Proving Ground. With the help of Blue Moon, he constantly adjusted and verified in this world, and invented various updated formations and spells that can be used in the rules of this world. Coupled with his own experienced cultivation ability, coupled with the strength of his own extreme twin fires, his current cultivation speed was almost several times that of ordinary cultivators. The formation of ninety-nine eighty-one twin fire vortex made the speed at which he absorbed mana even more terrifying.

Since completing the setting of the Nine Nine Eighty-One Twin Fire Vortex Absorbing Spiritual Power Mana Formation, Zhang Yuan himself did not need to absorb it through his divine consciousness and mind, and his mana was already able to improve on its own.

At this time, Wang Chongyang did not cultivate, and when Zhang Yuan returned to his room, he had been silently feeling Zhang Yuan's cultivation state at this time. Originally, they also planned to use guò's own powerful mana to help Zhang Yuan, making the fire spirit power around him even stronger. As soon as Zhang Yuan's Nine Nine Hundred and Eighty-One Twin Fire Vortex Formation was unleashed, this supreme powerhouse realized that his worries were completely unnecessary. Even he was surprised, what happened to Zhang Yuan when he fell to the ground, or Zhang Yuan had the great wisdom of demons, and he was able to obtain the mystery of such a formation or create such a powerful formation.

More than four months have passed, and during this time, under the condition of Wang Chongyang's full effort, Zhang Yuan is like a sponge that absorbs water, and has learned many techniques in the cultivation realm and the rules of energy operation in this world, as well as many tricks.

Under Wang Chongyang's guidance, Zhang Yuan transformed the ninety-nine-eighty-one double-fire vortex into two in his body, becoming the ninety-nine-eighty-one yang fire vortex of the sun true fire and the ninety-ninety-eighty-one yin fire vortex of the extinguishing dark fire, which directly increased the speed of absorbing the spiritual power of fire. As soon as the double formation method was in operation in Zhang Yuan's body, the fire spiritual power that was dozens of miles away echoed from afar and was summoned. In addition, there are dozens of extinct volcanic craters next to the seaside place chosen by Wang Chongyang, which used to be active volcanoes with very active eruptions. The rich fire spiritual power under this extinct volcano made Zhang Yuan's cultivation very fast.

During this period of time, Zhang Yuan has been working hard to cultivate, although under the care of Wang Chongyang, Zhang Yuan did not teleport to the demon realm magma lake and sea for cultivation, but now he has perfected the two ninety-nine-eighty-one vortices of yin and yang twin fires, and there are many volcanic conditions next to it. Now that he is not cultivating in the magma lake and sea of the Demon Realm, his speed is the same.

On this day, Zhang Yuan, who was already a three-star tenth-level student, suddenly realized his cultivation. His extreme twin fire echoed with the dual-attribute fire spiritual power in the air, almost in an instant, the sky was suddenly covered with red and blue, and the fire spiritual power in the sky turned into a fire cloud, the fire cloud was relatively small at first, but it quickly began to expand. It didn't take long for the fire clouds in the sky to increase tenfold, and they were still growing.

At this moment, suddenly a burst of black and golden-red flames erupted, and the thatched house suddenly turned to ashes. And Wang Chongyang rushed out of the house that was turned into ashes, he stood on the beach, quietly looked up at the vision in the sky, and watched the huts and flowers in the small courtyard turn to ashes, and his face couldn't help but change slightly.

Looking at the expansion of the cloud of fire spiritual power condensed in the sky, Wang Chongyang said to himself: "Such a strange atmosphere is better than that of people who have broken through the nine-star level. It's really a strange talent, could it be that Zhang Yuan is a master who is destined to achieve the position of an immortal, it seems that the time has come for the cultivation world to overwhelm the demon cultivation world! ”

At this time, Zhang Yuan's Yin and Yang Twin Fire Two Eighty-One Vortex Formations came out of his body, and the huge Twin Fire Cloud in the air and the two Extreme Twin Fire Formation Vortexes beside Zhang Yuan all began to rotate, and the speed of rotation became faster and faster. But no matter what, they have always maintained a balance of yin and yang. The sky gradually turned into a scene like a red and blue yin and yang fish.

A strange scene suddenly appeared in front of Wang Chongyang's eyes, and beside Zhang Yuan, there were one hundred and sixty-two positive and negative yin and yang extreme twin fire whirlpools in black and golden red. And in the mid-air above his head, a huge red and blue vortex formed a huge fire cloud of yin and yang fish. The two whirlpools echo each other, producing a majestic atmosphere that verifies each other and grows with each other.

Seeing this, Wang Chongyang suddenly gasped and said to himself: "The sky is visionary, and the gods and men will come out!" It is said that the gods of ancient times had strange visions when they broke through. It's the ultimate double fire that has never been seen before! Achieve immortals! O gods! My bottleneck has arrived, and I'm afraid I won't be able to continue to break through it for the rest of my life, only up to you. My apprentice grandson. Saying this, Wang Chongyang showed a look of envy. That's right, a generation of supreme powerhouses in the cultivation realm actually showed a look of envy for their disciples.

At this time, Zhang Yuandi, who was sitting there, became more and more solemn, and the two positive and negative yin and yang vortex formations around his body rotated faster and faster with the golden-red and black yin and yang vortexes. And the sky was also completely illuminated by the huge two-color fire spirit power vortex fire cloud, echoing from afar, the three two-color yin and yang totems above Zhang Yuan's head shone brightly.

As the ten light beads below the two-color totem blurred and condensed, a lightning bolt seemed to light up in mid-air, and the fire clouds in the air floated down. The huge Twin Fire Spiritual Power Energy and the Yin and Yang Extreme Twin Flames around Zhang Yuan's body were fused into two Nine Nine Vortex Formation Formation Vortexes.

In an instant, an incomparably surging mana fluctuation first released outwards and exploded, and then suddenly converged. At this time, Zhang Yuan's body suddenly emitted a dazzling light and a black obscure. Zhang Yuan's left side at this time was shining with a golden-red light like the sun during the day, dazzling and abnormal. His right side was pitch black, and he couldn't see his fingers.

The golden-red and black light condensed, and the two-color flame light condensed all the way to the top of Zhang Yuan's head, and finally turned into two small and extremely condensed clouds, a golden-red Sun God Bird King and a black Hell Annihilation Phoenix Hades Tuteng. Subsequently, the two totems merged into a golden-red Sun God Bird King and a black Hell Annihilation Phoenix Hades Cross Totem of the Double Extreme Flame Divine Beast, and Zhang Yuan's fourth-star totem finally broke through.

However, there was still a huge amount of energy left, and it gradually condensed into glowing light beads. To Wang Chongyang's surprise, the light bead representing the level under the totem on Zhang Yuan's head at this time was not the one that it should have just broken through the bottleneck, but was simply promoted to three by the huge double fire cloud energy. In other words, at this time, Zhang Yuan's mana level was not a four-star level, but a four-star third-level cultivator.
