Mu Yu accidentally entered an unknown cave. As soon as he stepped into the cave, Mu Yu felt a cold air hit his face, as if he had stepped into another world.
The environment inside the cave is dark and deep, as if it is the intersection of the yin and yang worlds. Mu Yu moved forward cautiously, his heart full of vigilance. Suddenly, he felt something hard stepped on under his feet. He bent down and picked it up, and found that it was a stone tablet.
There were some ancient words engraved on the stone tablet, but Mu Yu didn't recognize them. But he could feel an ancient and mysterious power emanating from the words, as if they were telling something. Mu Yu intuitively told him that this place must be a treasure.
After walking for a while, Mu Yu's vision gradually adapted to the light in the cave. At this time, he was surprised to find that the scene in front of him seemed to be in a fairyland. There is a wide lake deep in the cave called "Yin Yang Spring". The lake has an endless supply of water and is right at the intersection of yin and yang, hence its name. The lake water is divided into two parts, one side is golden yellow, as bright as the sun; the other side is silvery white, as bright as the moonlight. The two colors blend with each other to form a strange picture.
Continuing to move deeper, Mu Yu gradually felt the wonders inside. The interior space of the cave gradually expanded, forming a huge cave. There are so many geniuses and treasures in the cave, some spiritual grasses and fairy mushrooms exude a charming light, and some ancient spiritual mineral stones contain powerful energy.
Mu Yu felt happy and began to collect various treasures. Suddenly, he discovered a spring. There is a stone tablet next to the spring with the words "Yin Yang Spring" written on it. Mu Yu felt a mysterious power emanating from the spring, which made him feel in awe.
At this moment, Mu Yu suddenly heard a voice. The sound came from the spring, as if it were the call of the spring. The voice was full of mysterious power, which filled Mu Yu with fear.
It's like being at the intersection of two worlds. The light deep in the cave is dim, but it has a mysterious atmosphere. Mu Yu held his breath and moved forward cautiously.
At the end of the cave is a vast underground world. This place is like a natural underground palace, with countless genius treasures scattered everywhere, shining with alluring light. Mu Yu stared at everything in front of him in stunned silence, his heart filled with surprise and curiosity.
Suddenly, his eyes were attracted to a spring. The two sides of the spring are carved with patterns of yin and yang and two fish, exuding an ancient and mysterious atmosphere. Mu Yu took a closer look and saw two masses of liquid, one red and one white, suspended in the spring water, like the essence of the sun and moon condensed here.
At this moment, an ancient and majestic voice came from the depths of the cave: "Welcome to the treasure land of Yin Yang Spring. Countless geniuses and treasures are gathered here to help you practice. However, you must first stimulate the Yin Yang Spring. The true fire of the sun and the essence of the moon.”
Mu Yu's heart tightened, and he turned around to look and found several strange runes carved on the stone wall deep in the cave. He observed carefully and found that these runes contained the Tao of Yin and Yang, and seemed to provide a steady stream of energy to the spring water.
He took a deep breath, sat cross-legged, and began to mobilize the true energy in his body. As the Qi circulated, he gradually felt the energy in the spring pouring into his body like a trickle. This feeling made him relaxed and happy, as if he had merged into the world.
Gradually, Mu Yu's true energy merged with the energy in the Yin and Yang spring water, turning into a ball of golden light. Suddenly, golden light burst out and turned into two flames, one red and one white. The flames rose above Mu Yu's head, like the essence of the sun and moon burning blazingly.
Mu Yu took a few steps back, feeling a little flustered. But when he heard the sound again, he understood its purpose. The voice told him that this yin and yang spring water could stimulate the true fire of the sun and the essence of the moon, and had unparalleled power.
Mu Yu's heart moved, and he knew that it might be fate that he came here by mistake. So he approached the spring and prepared to be baptized by the Yin and Yang Spring.
Just when Mu Yu was about to touch the spring water, he suddenly felt a powerful force emanating from the spring. This force was like a great beast, instantly surrounding him.
Mu Yu's heart tightened, feeling as if he had been thrown into an endless abyss. The surrounding scene changed instantly, and he saw light spots flickering faintly in the darkness. These light spots are dotted in the darkness like stars, exuding mysterious power.
Suddenly, a huge ball of light emerged from the darkness. The light group contains countless light points, emitting dazzling light. These rays of light gradually condensed into two balls of light, one red and one white, just like the sun and the moon.
The red light ball exudes a fiery aura, as if it is burning with fire. The white light ball exudes a cool light, as if it is condensed with ice and snow. The two light balls intertwined with each other, as if dancing.
Mu Yu felt as if he was being attracted by these two balls of light, and his body began to tremble slightly. He felt that there was a resonance in his body, as if the true fire of the sun and the essence of the moon were being awakened.
As time goes by, the red light ball and the white light ball begin to converge toward the middle. They merge together to form a larger light group. This light group exuded even more powerful power, making Mu Yu feel palpitated.
Suddenly, the light group burst out with a dazzling light, which seemed to illuminate the entire universe. This ray of light penetrated Mu Yu's body and made him feel a strong tremor.
At this moment, Mu Yu suddenly felt a new power coming into his body. This power comes from the fusion of the true fire of the sun and the essence of the moon, filling his body with hot and cold auras.
At this moment, Mu Yu suddenly felt a strong sense of crisis. He immediately looked around vigilantly, only to find a strange sound coming from the depths of the cave. He nervously looked in the direction of the sound, and saw a huge monster appearing at the end of the cave, exuding terrifying coercion.
The monster seemed to have been triggered by Mu Yu and rushed towards him quickly. Mu Yu did not dare to neglect and immediately launched a counterattack. After a thrilling fierce battle, Mu Yu finally succeeded in defeating the monster with wit and courage. During the battle, he also discovered an astonishing secret: this monster was not a real creature, but the guardian of the power of the Yin and Yang Spring, bred by the power of heaven and earth.
After the guardian monsters were eliminated, the mysterious power of the Yin Yang Spring Treasure Land finally began to take effect.
Wave after wave of powerful energy gushes out from the Yin Yang Spring and flows through his body like a river flowing into the sea.
