The flame-like wave of qi, the temperature was extremely high, and as soon as it appeared, a blazing wind hung up and swept out.

"Whew!"

Fortunately, Li Ke had already noticed it, otherwise this time, he would have been burned to ashes by the blazing wind.

Li Ke's figure retreated, and he was surprised in his heart, the cold and piercing cold spring unexpectedly spewed out flame-like qi waves, such a situation made him puzzled for a while.

"Whew!"

Quickly transported the power of the divine soldiers, turning into air currents, circulating sharply, blocking the blazing wind, and at the same time unfolding the Nine Dragons of Swimming Fish, quickly retreating backwards.

"Huh! The flame's spark is blue!"

The red flame rushed out from the cold spring spring, several meters high, red and shiny, illuminating all the surrounding space, and in the red flame, a faint ray of blue spark, although only a few inches high, exuded another extremely cold aura, with Li Ke's extraordinary perception, he could naturally perceive it.

"The cold spring is yin, the flame is yang, the cathode produces yang, and the anode produces yin...... Could this flame be one of the most unique and priceless heaven and earth auras on the Divine Soldier Continent in the legend!"

"Xuanyang Qi!"

Li Ke looked at the red flames and the dark blue sparks, and his heart was shocked, he had seen a book about the most unique and priceless heaven and earth aura in the Divine Soldier Continent when he was in the Li family.

The book says: Heaven and earth aura, born in the universe, condense Xuanhuang, fuse the five elements, infinite use, unparalleled in the world, a soldier, once he gets a wisp of heaven and earth aura, this is his most anti-heaven creation, because the heaven and earth aura can be fused on the soul of the soldier, so that the soul of the soldier has its unique effect.

Each unique heaven and earth aura has a different effect.

Li Ke knew that there were only nine kinds of heaven and earth aura in the Dao, but he knew that in the Dao of the Divine Soldiers, there were far more than nine kinds of heaven and earth aura.

The nine kinds of heaven and earth aura he knew of the Dao were each of different uses, among which the dragon qi was the most ferocious, the tiger qi was the most violent, and the sharpest Jinni qi, the earth pan qi known for its defense, and so on.

And the red flame in the cold spring spring was the Xuanyang Qi, one of the nine kinds of heaven and earth spiritual qi that Li Ke knew.

"The qi of Xuanyang is the most rigid way, known as invincible, indestructible, incomparably tough, as long as the soldier's soul is fused with the spirit of Xuanyang, the soul of the soldier has the strength of indestructible and unbreakable, and can overwhelm the opponent with high soul and high skill, and the effect is the most significant. ”

"It's so rare!"

Li Ke's eyes shot out wisps of fine light, and he was surprised, seeing ten spirit stones was already good luck against the sky, but he didn't expect that this cold spring spring was actually cathode and yang, brewing into a wisp of Xuanyang qi.

"If my flying knife soul refines this wisp of Xuanyang Qi, then my flying knife will have the strength of indestructible and indestructible tenacity, coupled with the domineering determination of my condensation and cultivation of the Martial Realm, when the time comes, my flying knife will be even tougher than the orange sixth-rank soldier soul and even the yellow fifth-rank soldier soul!"

"It's as easy as breaking their soldier souls, but it's extremely difficult for high-level soldier souls to break mine!"

Thinking of this, Li Ke's face showed a look of extreme excitement, the aura of heaven and earth is unique, how rare, not all places can appear, for thousands of years, there are very few aura of heaven and earth in the Divine Soldier Continent.

"Luck, luck! This is really thanks to the elder of the Golden Light Gate!" Li Ke was pleasantly surprised, if it weren't for the elders of the Golden Light Gate forcing him into the center of the Cold Spring Mountain Range, he would not have been able to enter the ancient peaks, and naturally he would not have had the opportunity to obtain this wisp of heaven and earth aura.

If the middle-aged elder of the golden light, Qiu Fa, knew all this that had happened, I am afraid that he would come back to life and fight with him.

Xuanyang Qi, the heaven and earth charm treasure coveted by countless soldiers, this can be compared to high-level exercises, the art of war, money, more attractive, heaven and earth aura, is a priceless treasure, not everyone can get it.

Li may have had such an opportunity to obtain this wisp of Xuanyang Qi, which is completely his creation.

"To refine the aura of heaven and earth, you need to communicate with it with the soul of a soldier!"

Li Ke thought of the introduction in the book on the record of heaven and earth aura, if you want to fuse the aura of heaven and earth, you must communicate with it with the soul of the soldier, so that the two can slowly adapt, so that you can fuse the aura of heaven and earth.

Stop his body, stop in the distance, use the power of the divine weapon to resist the invasion of the Xuanyang flame, and at the same time condense the soul of the soldier, the red flying knife, the blade is translucent, Li Ke sat cross-legged, suppressed the excitement, and slowly controlled the flying knife soul to fly towards the red flame-Xuanyang Qi.

"As long as I refine this Xuanyang Qi, my Flying Knife Warrior Soul will not only become indestructible, but even my skill will be increased by one or two levels!"

According to the records in the books, each heaven and earth aura not only has the most unique effect, but also contains a powerful divine qi, which can directly improve the skill of the soldier.

"Buzz!"

As soon as the flying knife came out, it collided strongly with the red flame sword manifested by Xuanyang Qi, and Li Ke immediately felt that Xuanyang Qi emitted a repulsive force, resisting the advance of his flying knife soul.

Clenching his teeth, Li Ke picked up the little divine weapon power left in his body and rushed towards the flying knife soldier soul that flew out.

The red throwing knife became more and more red, slowly moving forward like a turtle crawling.

"This Xuanyang Qi is far beyond my imagination! The Dao is extremely strong, and I must be vigorous in one go! Otherwise, I will probably be burned to death by the Xuanyang flame!"

Li Ke felt the difficult advance of the Flying Knife Soldier's Soul, almost a foot forward, it consumed a large part of his divine weapon's power, and the strength of Xuanyang's Qi was far beyond his cognition.

Fortunately, Li Ke cultivated the Qi Condensation Realm twice before and after, and the qi of the divine soldiers stored in him was much more than that of ordinary soldiers, and the power of the divine soldiers that could operate was naturally much more.

If it weren't for this, when his skill was three times lower than that of Zhongqing, it would be impossible for Zhongqing to run so far without the power of the divine soldier.

Later, when the old man in brocade appeared, he swallowed a few more alchemy pills, and slowly recovered the power of the divine soldier.

At this time, Li Ke knew that he was too careless, the aura of Xuanyang was not as simple as he imagined, this unique aura of heaven and earth, each of which was extremely mysterious, extremely weird, and very dangerous.

Li Ke is a master of the martial arts of the triple realm of refining, where can he easily bear it.

"Wealth is in danger!

Li Ke's expression changed, his face was full of perseverance, and he used all his strength to transport the qi of the divine soldiers, and at the same time, the qi of the divine soldiers turned into a torrent, like ten thousand swords flying, the crazy sword broke through the air, and rushed into his body frantically.
