After the heavy rain, the sky shone like a wash, and Yang Kai left the vast ancient wood forest and went straight to the Southern Desolate Heavenly Sword Sect.

The sword blade feather was majestic, his eyes shone with a scorching light, the power of the Great Sage was undisguised, Yang Kai came again, beyond his expectations, when he learned the purpose and intention of Yang Kai's coming, he was quickly relieved, and said with a slight smile: "The Southern Wilderness belongs to the hot land, and it is a coincidence that the Heavenly Sword Sect has really mastered a fire in the center of the earth, so the weapons created by the Heavenly Sword Sect are sharper than ordinary blades." ”

Affirmed, Yang Kai was overjoyed, the first time he arrived in the Southern Wilderness, he felt the blazing heat, and said: "Seniors, juniors still have to use the fire of the center of the earth to temper the Dao weapon, hoping that the seniors will be perfected." ”

Jian Feng Yu did not refuse Yang Kai's request, he punched out the Dao Dao Seal with both hands, and in an instant, a portal with intertwined patterns appeared in the main hall of the Heavenly Sword Sect, and the blazing flames burned in front of the portal, as if the entire Cangyu was going to be burned, Yang Kai followed closely behind Jian Feng Yu, and immediately, the Sealing Heaven Seal in the Sea of Consciousness seemed to be stimulated, and the nine ancient characters shone brightly, falling down the Dao Red Golden Brilliance, covering Yang Kai's body surface, firmly protecting the treasure body.

Jian Feng Yu was surprised by the strength of Yang Kai's physical body, even if he was a great sage, he would feel pain in his body if he wanted to shuttle through the blazing fire Lang space, and the young man in front of him, although he knew that his body was protected by treasures, he also secretly sighed at Yang Kai's endurance, Jian Feng Yu had no feeling for Fire Lang, it was completely because he had arranged the complicated Dao patterns, and it was not affected.

After entering the blazing light gate, the route under the feet of Jian Feng Yu and Yang Kai was slowly sinking, and his intuition told Yang Kai that they must be walking in the direction of the center of the earth, as the journey progressed, the fire Lang became more and more blazing, and it had changed from bright yellow to red, gradually, the color of the flame was still changing, the temperature was gradually rising, and the surrounding rock walls were flowing with scorching magma.

If attacked by these magma, a strong person as strong as the Guiding Path Realm will also be incinerated to ashes.

In the sea of knowledge, the Seal of Heaven slowly rotated, and the nine ancient characters had left the surface of the Seal of Heaven and rotated rapidly in the sea of knowledge, and the red gold brilliance that fell became thicker and thicker, like a waterfall falling from the nine heavens, spreading to Yang Kai's limbs and hundreds of remains, and immediately, Yang Kai's body surface quickly condensed a layer of red armor, shining brightly.

This change stunned Jian Fengyu, and he muttered, "This is this"

Yang Kai habitually touched his chin, he had already thought of the wording, and said: "The autonomous change of the Ring of Annihilation, thanks to it, otherwise I really wouldn't be able to enter the center of the earth." ”

The Ring of Annihilation is in Yang Kai's hands, and all the monks in the Immortal Cultivation World know it, this explanation is also reasonable, and Jian Fengyu is not suspicious, and he is still leading the way.

The flames in front of him had turned red, and the red armor on Yang Kai's body was becoming more and more condensed, blocking the vast flames out, and the real body seemed to be in a world of spring flowers, which was affected in the slightest.

The sound of "boom" like the air burning was endless, shaking the eardrums buzzing, and the fire in front of them changed, and the red color had turned purple.

Before entering the purple flame, Jian Fengyu suddenly stopped his figure, and said with a solemn face: "Yang Kai, the front is the center of the earth, and I can't involve the purple flame, otherwise I will definitely suffer heavy damage, or even turn to ashes." Our Heavenly Sword Sect's sacrificial treasures are generally chosen to be in the red flame area, and no one has entered the purple flame area so far. ”

Before entering the purple flame area, Yang Kai felt that it was difficult to breathe, in the purple fire in front of him, all the aura was incinerated at some point, forming a vacuum flame area, for tens of thousands of years, no one had really entered this area, Yang Kai knew that what Jian Fengyu said was not a lie.

Yang Kai said: "My Yang family tempers the Dao weapon, and the fire in the center of the earth is an inevitable choice, and I can only risk my life." ”

Jian Fengyu nodded slightly, admiring Yang Kai's persistence and firmness, and said: "Yang Kai, think twice before acting, as far as I know, none of the powerhouses of your Yang family's cultivation of Dao Sutras, even if they are peerless figures who have ascended to the Great Sage Realm, have really relied on the fire of the heart of the earth to temper their own Dao Tools. ”

Hearing this, Yang Kai was stunned, the Dao Sutra has been passed down in the Yang family for a long time, since ancient times, no one has relied on the fire of the center of the earth to temper the Dao weapon, what is the record on the Dao Sutra, he couldn't help asking: "Didn't the monks of my Yang family who cultivated the Dao Sutra enter the office and their combat power has been greatly reduced?"

Jian Fengyu explained: "Not really, the Yang family's Dao Sutra is very mysterious, even if it can't rely on the fire of the center of the earth to temper the Dao weapon, but it can also rely on the ordinary way to temper the Dao weapon, although its combat effectiveness has been reduced, but compared with other monks, it still has a great advantage, in the same level of battle, few people can defeat the Yang family's people." ”

"I see!" Yang Kai suddenly realized, and said, "I want to take the strongest path, of course I have to temper the strongest treasure, and the fire in the center of the earth is my only choice." ”

Yang Kai was very resolute, the "three-pointed two-edged knife" was his favorite treasure, it was a battle-type treasure that he conceived in combination with the natural wisdom of the Dao Law in the Dao Sutra, and it could only be forged with the fire of the center of the earth to reach the strongest, and only with the three-pointed two-edged knife in his hand could he go further.

As a great sage, Jian Feng Yu didn't dare to enter the purple flame area at all, he was faintly worried about Yang Kai, even if the Ring of Silence was extraordinary, but Yang Kai could not be unharmed at all, he said: "Yang Kai, in fact, you can use the red flame to smelt and cast the treasure first, and then use the purple flame to temper it after the strength is strong, and the final effect is completely consistent." ”

Yang Kai didn't think about this path, Hongmeng Purple Gold circulated purple brilliance, which seemed to echo with the fire of the center of the earth, there seemed to be some kind of connection between the two, to cast the strongest blade, from the beginning, it was necessary to be invincible at the same level, this was Yang Kai's idea at the moment, and some other ideas and reasonable suggestions were all thrown out of the clouds by Yang Kai.

Yang Kai expressed his gratitude to Jian Fengyu for his suggestion, but he still chose the Purple Sea of Fire.

Yang Kai used his strength to run the Dao Sutra Mystery, and the Sealing Heaven Seal in the Sea of Consciousness was activated by the purple flame of the tyrant, and part of the energy was activated, and the brilliant red gold flowed, and the red gold armor on Yang Kai's body became more and more vigorous, and the protective power became more and more powerful, but after entering the purple sea of fire, Yang Kai felt that his entire body seemed to be burning, and his blood was like a galloping horse, rumbling, but in the end, under the protection of the red gold armor, his body and internal organs were not damaged in the slightest.

This was a vast sea of fire, the purple flames seemed to burn through the earth, Yang Kai relied on the Sealing Heaven Seal to move forward slowly, and every step was under tremendous pressure, even if he was protected by the red gold armor, he had to withstand the residual heat baking.

This was only the edge of the purple sea of fire, there was still some distance from the center of the earth, Yang Kai clenched his teeth tightly, and under tremendous pressure, the overflowing sweat was evaporated in an instant.

I have to say that the strength of the Sealing Heaven Seal, when the purple flame is more blazing, the surging brilliance it emits also becomes more and more blazing, always allowing Yang Kai's body to bear within a certain range.

"Huh!" Yang Kai's eyes flashed, and he was stunned by the flames that appeared in front of him, these flames were like fire crows, completely similar to the shape of the fire crows that appeared in mythology, bright eyes, sharp long beaks, floating wings, the only thing missing was life.

"If you give these fire ravens any more time, they will be living creatures thousands of years later. Yang happily made a judgment, and he passed through the sea of fire formed by the fire crow, and slowly advanced.

The more he walked in, the more unbelievable he felt, along the way, Yang Kai saw tigers formed by flames, heavenly wolves, etc., all kinds of animal shapes that could be handed over or could not be named in the world of cultivating immortals, it was simply the world of beasts.

"Huh!" Yang Kai was surprised again, the blazing purple flames, each flame was several zhang high, gathered into the shape of a unicorn, a phoenix and a divine dragon, they represented the supreme existence of birds and beasts, this kind of flame was extremely domineering, making Yang Kai seem to shoot out the Heavenly Seal in the sea of knowledge.

The flames constructed by the three divine beasts formed a protection, spreading to all directions, they are just the protective flames of the fire of the center of the earth, the real fire of the center of the earth is still some inside, Yang Kai looked at the magical scene, he took steps, slowly deepened, and finally reached the center of the earth, and saw the legendary fire of the center of the earth.

The fire in the center of the earth is not vast, the radius is only three zhang, but the range of these three zhang is extremely shocking, the pure purple flame is scorching and burning, the space above the flame is the purple hot Lang gathered into the heavens and stars, the sun, moon and stars are extremely dazzling, giving people a sense of oppression, and the pure purple flame below gathers into nine purple figures, back and forth in the flames, and there are mountains and rivers in the flames of the three zhangs, as if it is a condensed world.

"This is the fire in the center of the earth?" Looking at the shocking scene in front of him, he was stunned, he didn't expect that the fire in the center of the earth actually evolved into a condensed world, which was too incredible.

"The fire in the center of the earth is so magical, what about the fire of the day?" Yang Kai thought that after entering the Great Sage, refining the Dao Weapon needed to use the Heavenly Fire, which might be even more magical.

Yang Kai ran the Xuan Gong, adjusted his body and mind to the best state, tempered the Dao instrument, and did not allow the slightest sloppiness, let alone the outside world to disturb him, otherwise it would fall short, in front of the fire in the center of the earth, Yang Kai was not worried about foreign objects disturbing, he searched carefully, in this purple sea of fire, there were no living things at all.

He sat cross-legged in the sea of fire, conditioning his state, three hours later, "Huh, hey" opened his bright eyes, sealed his hands, typed out the Dao runes, and laid out the Wanhua Forbidden, the surrounding purple flames are for him to drive, once the foreign object approaches this place, it will definitely set off Wanhua Forbidden.

"Huh!" Yang Kai shook his hand, the three-foot-long Hongmeng purple gold flashed with blazing purple light, echoing this world, the blazing flames around it beat more and more, and the Hongmeng purple gold actually flashed purple veins on it under the illumination of the flames, and there were things similar to blood flowing.
