(Owed 270 updates,) When Ling Yun came back, he was still sitting cross-legged on the cliff not far from Ya'er's house. He did not approach the small bamboo house. Ever since the old man said those words to him that day, he had never been there. Did not enter the three small bamboo houses. Through his spiritual consciousness, he discovered that Ya'er was in the small bamboo house in the middle. She was sitting cross-legged on the white bed, practicing with her eyes closed, and as she breathed out, a faint spiritual energy lingered outside her body. This was the precursor to a breakthrough. Seeing this, Ling Yun smiled slightly. In just a few days, Ya'er was about to break through to the second level of Qi Refining. This shows how much sweat the girl has put in. Suddenly, Ling Yun noticed that Ya'er's slender eyebrows suddenly frowned and her delicate little face became a little pale, and he knew that the critical moment of breakthrough had been reached. For the first breakthrough, if there is no one to guide you, things can easily go wrong. However, Ling Yun had no intention of helping Ya'er. In his consciousness, the old man dressed as a fisherman suddenly broke in and entered without hesitation. , his fingers quickly tapped Ya'er's key acupuncture points several times. Just these few times, the turbulent Qi in Ya'er's body quickly calmed down. It flowed through the small meridians like running water, and finally gathered in the Dantian. The Qi sea in the Dantian gradually expanded, and finally expanded. Only when it reaches twice the level does it stop. Level 2 of Qi Refining. Equivalent to a fourth-level warrior. Sensing Ya'er's cultivation at this time, the old man exclaimed. If he were to teach Ya'er how to practice, even if Ya'er had a third-grade heavenly spiritual root, it would still take at least a year to break through to the realm of a warrior. Let alone a fourth-level warrior. But Ling Yun, in just a few hours, allowed Ya'er to directly cross the stage of martial arts servant and possess the cultivation level of a first-level warrior. This was very shocking to him, but he did not expect that Ya'er Under his nose, it was improving at a rate of one level per day. By the fourth day today, I have reached the fourth level of warrior. This speed is beyond the understanding of the old man. He knows Ya'er's talent and qualifications very well. She has a first-grade earth spiritual root of the gold system. But the current Ya'er has a real third-grade heavenly spiritual root. The old man knew that this was another masterpiece of that young man. Each of these things can only be described as a miracle. He didn¡¯t know how Ling Yun did all of this. Seeing that Ya'er successfully broke through to the second level of Qi refining with the help of the old man, Ling Yun smiled slightly, and then took out the wooden box given by Yun He from the spiritual ring. Holding the wooden box in his hand, it was bone-chilling, and his soul seemed to be frozen. Ling Yun knew that if it hadn't been for this wooden box, perhaps his origin energy would have been sucked away by the stone inside. Ling Yun opened the wooden box, and a sphere the size of a fist, like a hedgehog, appeared in front of his eyes. The sphere was completely black, and those tiny spikes emitted a faint black light, which was frightening. Ling Yun looked at the sphere and was not in a hurry to take it out for study. Instead, he said in his heart: "Tianhun, now you can tell me what this strange stone is." Ling Yun just finished speaking. , the childish voice of Tianhun came to mind: "Dad, this stone should not exist in Tianwu Continent. If I guessed correctly, it should come from outside the sky." "From outside the sky." "Yes, Dad, The so-called outer space refers to the vast universe, Tianwu Continent, which is actually the same existence as the earth where my father lived in his previous life, but the shape is different, but no matter what shape it is, it has a unified name, we all call it nebula. " Ling Yun looked at the stone in his hand and guessed: "Could this stone have fallen from a certain nebula in the universe?" "Yes, dad, it may be bigger than Tianwu Continent, but it will definitely not be smaller. It is rare for a stone to be so big after falling from the sky. "Ling Yun already knew the origin of this stone, so he asked again: "Then tell me about its function now." "Tianhun. Said: "In the universe, there are various types of nebulae, such as metallic nebulae, all of which are water nebulae, similar to the nebulae of Tianwu Continent and Earth." "The difference in nebulae also determines the life that can survive on the nebula. The bodies are also different, but generally speaking, in the vast world, less than 10% of the nebulae that can contain life forms may be less than 10%. "And the nebula that forms the soul-devouring stone is itself a nebula that emits extremely strong nuclear energy. The energy emitted by the core of the nebula can swallow most of the energy. This type of nebula is generally unable to survive life forms. " "The soul-devouring stone is the essence of this nebula, and its core energy is also there. The strongest, not to mention capable?, even if ordinary items come close to it, they will instantly turn into fly ash. " Ling Yun finally understood why this stone felt so dangerous. The energy it exuded was just like his source energy. It could assimilate, or swallow, the energy of all things in the world, and it was even stronger. " It's just that I don¡¯t know if my origin energy can swallow up the energy in this stone. ¡°Huh. " Ling Yun let out a heavy breath, and his eyes looking at the stone became even hotter. He said: "Tianhun, how does the energy emitted by this stone compare with the source energy in my body. " Tianhun was silent for a while, then guessed: "I don't know very well, dad, your origin energy is very mysterious. I believe that when dad's cultivation reaches a certain level, he will be stronger than this stone, but for now, you His cultivation level is still low and his Origin Qi is still very weak. Whether he can resist its devouring, I cannot predict. " For this result, Ling Yun was a little disappointed, but Tianhun finally didn't say anything. Since it was unpredictable, it meant that there was still hope. Even if the hope was slim, he would give it a try. "Dad, if you are If you can refine this stone, your source energy, even without any skills, will have the attribute of devouring it. "Tian Hunyu said in astonishment. Ling Yun was happy, but soon became serious again: "I'm afraid the refining time is not short. Even if I can refine it, I only have six days now. Six days Can it be successfully refined? " If he can't refine this stone within six days, then he might as well evolve his technique safely. After all, this refining is still very risky. " It's up to you. Anyway, even if I don't tell you, you Also try to refine it. "Tianhun curled his lips and said disdainfully. It also has a close connection with Ling Yun. How could it not know Ling Yun's character? Ling Yun shrugged and ignored Tianhun. Looking at the stone in the wooden box, he stretched out his left hand and placed it on top of the stone. , a faint halo appeared in the palm of his hand, and then slowly approached the stone.
