The spiritual energy of heaven and earth, the mysterious yang energy, has changed once today, at the fourth watch.

  A flame-like air wave with extremely high temperatures suddenly appeared and was followed by a fierce gust of hot wind that swept out.

  "Ah!"

  Fortunately, Li Ke had already noticed it, otherwise he would have been burned to ashes by the scorching gust of wind.

  Li Ke's figure retreated, his heart filled with shock and amazement. The icy cold spring suddenly spouted out flame-like ripples, a situation that left him momentarily bewildered.

  "Hoo-hoo!"

  Quickly mobilize the power of the divine soldiers, transform into a stream of air flows, rapidly flowing and turning, blocking the scorching hot wind, while unfolding the Nine Dragon Transformation of the Swimming Fish, quickly retreating backwards.

  "Huh! The spark of the flame is actually blue!"

  A crimson flame burst out of the cold spring's source, shooting up several meters high, its bright red light illuminating the surrounding space. Amidst the crimson flames, a faint blue spark flickered, only a few inches high, yet emitting an eerie and extremely chilly aura that Li Ke's extraordinary senses could naturally detect.

  "The icy spring is yin, the fierce flame is yang. When yin reaches its extreme, it gives birth to yang; when yang reaches its extreme, it gives birth to yin... This flame, could it be one of the legendary, most unique and priceless heavenly spiritual energies of the Divine Land Continent?"

  "Essence of Yang!"

  Li Ke gazed at the crimson flames and indigo sparks, his heart shaken to the core. He had once seen a book about the most unique and priceless heavenly spiritual energy of the Divine Continent in the Li family's ancestral home, the number one divine sword clan.

  The book introduces: The spiritual energy of heaven and earth, born in the universe, condensed into a mysterious yellow, merged with the five elements, its uses are endless, unparalleled in the world. It is also known as the "Soldier". Once one obtains a strand of heavenly spiritual energy, this becomes his most rebellious creation, because the heavenly spiritual energy can be merged onto the soldier's soul, allowing the soldier's soul to possess its unique effect.

  Each unique heavenly spirit has different effects.

  Li Ke knew that there were only nine kinds of heavenly and earthly spiritual energy, but he knew that on the continent of Shenbing, the heavenly and earthly spiritual energy was far from just nine kinds.

  He knew nine kinds of heavenly and earthly spiritual energies, each with a different use. Among them, the dragon's march energy was the most ferocious, the tiger's fierce energy was the most violent, there was also the sharpest golden nirvana energy, the defensive earth pan energy and so on.

  And in the cold spring's eye, the red flame was one of the nine kinds of heavenly and earthly spiritual energy that Li Ke knew, the Xuan Yang energy.

  "The Xuan Yang energy is the most unyielding and powerful, known as unstoppable and indestructible. Once a soldier's soul merges with the Xuan Yang energy, their soul will possess an unyielding power that can crush any opponent, no matter how strong they are."

  "What a rare find! It's really too rare!"

  Li Ke's eyes shot out strands of brilliant light, shocked and delighted. Seeing ten pieces of spiritual stone was already a reversal of fortune, but unexpectedly, this cold spring actually gave birth to a strand of mysterious yang energy.

  "If my Flying Dagger Soul refines this strand of Mysterious Yang energy, then my Flying Dagger will possess the power to shatter all obstacles and destroy all objects. Adding that to my Qi Condensation Realm's Overbearing Decision, my Refining Soldier Realm's Wind Cloud Decision, at that time, my Flying Dagger will be even more powerful than an Orange Sixth-Grade Soul Soldier, or even a Yellow Fifth-Grade Soul Soldier!"

  "It's easy for me to shatter their soldier souls, but for high-level soldier souls to shatter mine is extremely difficult!"

  At this thought, Li Ke's face showed extreme excitement. The heavenly and earthly spiritual energy was extremely rare; not every place could produce it. In the thousands of years since the Divine Land, only a few heavenly and earthly spiritual energies had appeared.

  "What luck! I must thank the elder of Golden Light Gate!" Li Ke was overjoyed. If it weren't for the elder of Golden Light Gate forcing him into the center of the Frostbite Mountains, he wouldn't have been able to enter the ancient mountain peak and naturally wouldn't have had the chance to obtain this strand of heavenly spiritual energy.

  If Elder Qiu Fa of the Golden Light knew about all this, he would probably be so angry that he would come back to life and fight with him.

  The aura of the mysterious yang, countless warriors' dream of acquiring the heavenly treasure, this is more attractive than high-level skills, martial arts, wealth, and it's priceless, not everyone can get it.

  Li may have such a chance to get this strand of mysterious Yang energy, which is entirely his good fortune.

  "Refine the spiritual energy of heaven and earth, you need to communicate with it using the soul of a soldier!"

  Li Ke thought of the introduction in that book about recording the spiritual energy of heaven and earth. If he wanted to merge with the spiritual energy of heaven and earth, he had to communicate with the soul of the sword, allowing the two to slowly adapt to each other, so that they could merge with the spiritual energy of heaven and earth.

  Stop the body, stay far away, and use the divine soldier's power to resist the invasion of the Xuan Yang flames. At the same time, condense the soul of the soldiers into a red flying knife with a sharp blade. Li Ke sat cross-legged, suppressing his excited mood, slowly controlling the flying knife to fly towards the crimson flames - the aura of Xuan Yang.

  "As long as I refine this Xuan Yang energy, my Flying Dagger Soul will not only become invincible, but my abilities will also increase by one or two levels!"

  According to the records in the book, each of the heavenly and earthly spiritual energies not only has a unique effect but also contains powerful divine soldier energy, which can directly enhance the combatant's abilities.

  "Hum!"

  The flying knife was released, and the red flame sword that had been transformed by the Xuan Yang's energy collided violently with it. Li Ke suddenly felt a repulsive force emitted by the Xuan Yang's energy, blocking the advance of his Flying Knife Soldier Soul.

  Gritting his teeth, Li Ke mobilized the remaining divine soldier's power within his body and charged towards the flying dagger-like soul of the Flying Dagger Soldier.

  The red flying knife became increasingly crimson and moved forward slowly like a turtle crawling.

  "This Profound Yang energy far exceeds my imagination! The path is treacherous, I must press on with all my might! Otherwise, I may be burned to death by the Profound Yang flames!"

  Li Ke felt the Flying Dagger Soldier's arduous advance, almost every inch forward consumed a large part of his divine soldier's power. The grandeur of Xuan Yang's energy far exceeded his understanding.

  Fortunately, Li Ke had practiced the Condensing Qi Realm twice before and after, so the divine soldier's energy stored in his body was much more than that of an ordinary soldier. The power of the divine soldier he could manipulate was naturally many times greater.

  If it weren't for that, with his strength being three times lower than Zhong Qing's, he wouldn't have been able to run that far with her after she lost the power of the divine weapon.

  Later, when the old man in brocade appeared, he swallowed a few more Lianbing Dan, and slowly recovered his divine soldier's power.

  At this time, Li Ke knew that he had been too careless. The Xuan Yang energy was not as simple as he had imagined. This kind of unique and mysterious heavenly energy, each one was full of mystery and danger.

  Li Ke is a master of the three-layered boundary of martial arts, where he can easily withstand.

  "Wealth and honor are won in the midst of danger! I'll give it a shot!"

  Li Ke's expression changed, his face filled with determination, he fully activated the divine soldier's energy, at the same time activating the Wind Cloud Decree. A surge of divine soldier's energy transformed into a torrent, like ten thousand swords flying and dancing, madly slashing through the air, crazily rushing into his body.
