Oh my god! The goddess secretly gave birth to three obedient daughters for me

The Black Mountain old demon stood dumbfounded on the spot, unable to regain his senses for a long time, his eyes wide with disbelief. Hei Feng, that was his personal bodyguard, the most capable subordinate by his side. Hei Feng was half a step into the realm of immortals, with combat power comparable to the Nascent Soul Stage—indeed a renowned figure within Black Mountain City. But this young man in green, with just one punch, had instantly killed Hei Feng; it was horrifying, terrifying! Could this young man in green truly possess some peculiar secret technique, as the rumors suggested? Otherwise, how could he have such heaven-defying strength! "Black Mountain old demon, I advise you better release me. Otherwise, I won't be courteous. I can assure you, if I weren't in this ancient cave, I would have slain your people long ago." Lin Yifei arrived at the cave entrance and said indifferently to the Black Mountain old demon inside, his tone calm and unwavering. "Hmph, boy, don't be arrogant. I will capture you now, and then have Hei Feng refine you!" "How daring!" Lin Yi snorted coldly, a formidable dark aura burst forth from his body, enveloping the entire cave and causing the temperature within to plummet. "This kid's dark aura is terrifying, even more sinister than that of the Black Mountain old demon. No wonder he dares to provoke the Black Mountain old demon!" The Black Mountain old demon was inwardly aghast, his eyes filled with panic. This surge of dark aura made the Black Mountain old demon feel icy cold all over, as if suffocating. He didn't dare to delay, his figure flickered, and he vanished from the cave entrance in an instant, leaving no trace behind. Although the Black Mountain old demon was more powerful than Hei Feng, he did not possess Dark Divine Power and could not use the dark aura. Therefore, under the oppression of the dark aura, he felt as if he had sunk into a quagmire, his movements became sluggish, and his speed was greatly reduced. "Hmph!" Seeing the Black Mountain old demon flee, Lin Yi snorted coldly, his figure also disappeared from the cave. Shortly after the two vanished, Hei Feng appeared in the cave. Hei Feng's gaze swept around, but he could not find any trace of the Black Mountain old demon. "Where is the Black Mountain old demon?" Hei Feng asked with a frown. "Lord Hei Feng, we just saw the Black Mountain old demon leave with that young man. We don't know their destination," Hei Feng's subordinate hurriedly reported. "Hmph! Can he run away? I'll pursue immediately!" Having said this, Hei Feng's figure also flashed, disappearing without a trace. With Hei Feng taking the Black Mountain old demon away, Lin Yi continued to move forward in the cave. The Black Mountain old demon's strength was far beyond that of Hei Feng. He was incredibly fast and disappeared from Lin Yi's sight in almost the blink of an eye, leaving Lin Yi staring dumbfounded at the place where the two had departed. "Damn it! How can the Black Mountain old demon be so fast? My speed can't even catch up with him!" Lin Yi frowned and said. Although he could shrink the ground beneath his feet to cover a kilometer in an instant, he was leagues behind the Black Mountain old demon. "My speed cannot fully burst forth. To completely unleash it, I need to consume a large amount of blood essence and Soul Power. Right now, I simply can't do it." Lin Yi shook his head. "However, the Black Mountain old demon's Physical Body has been taken by me, and he will surely hate me to the bone. Once he knows my whereabouts, he will surely strike at me, so I must improve my strength as soon as possible." Thinking this, Lin Yi quickened his pace and moved forward. "Eh? This cave is strange; I can't seem to reach the end, as if blocked by a Great Formation, unable to move forward!" Not long after, Lin Yi halted, his brow slightly furrowed, his expression turning serious. "It seems to be a trapping Formation; I can only proceed to the next area by breaking through the Formation." Lin Yi pondered for a moment, then with a thought, a dazzling Purple Gold Thunderbolt burst forth, transforming into a silver-white armor that covered his body, with a purple Divine Sword suspended above his head. "Buzz!" The Purple Gold Thunder and the silver-white thunder merged into one, forming a Thunder Lightning Divine Sword radiating purple thunder light! This was a set of purple gold armor he had plundered from within the cave dwelling, boasting astonishing defensive power and possessing some amplifying functions, able to enhance attacks, enhance defenses. "Go!" Lin Yi let out a low shout, stimulating the Thunder Lightning Divine Sword and slashing fiercely forward, a huge purple gold sword light roaring out, directly cleaving towards the spatial barrier ahead. "Bang!" A loud collision sounded as the sword light struck the spatial barrier, which instantly shattered, revealing the scene ahead. In front of him lay a pitch-black corridor, and in front of the pitch-black corridor stood a massive stone door, engraved with a pitch-black demonic beast totem, emitting waves of dark mist, rendering the entire corridor chilling and terrifying, filled with an eerie aura that made one's skin crawl. "Is this a maze?" After seeing the scene clearly, Lin Yi could not help but frown. A maze! This was a maze! Within the pitch-black corridor in front of Lin Yi, there were stone chambers, each embedded with various restrictions. These stone chambers were all built from different types of stones and were extremely hard, containing terrifying power, forming a highly dangerous maze. Once someone entered the stone chamber, they would be trapped to death, never able to leave again, perhaps remaining there forever until death or devoured by those dark and evil creatures. "It seems that to enter the maze, I must first dismantle the restriction. Once I have destroyed all the restrictions within the maze, I will be able to leave the maze." Lin Yi pondered for a moment before he had an idea in mind. "Swoosh!" Lin Yi stepped forward and appeared inside a stone chamber. "Boom!" Within the chamber, the stone walls trembled as huge black boulders fell from above. These black boulders were all piled up, reaching hundreds of feet tall, densely packed, blocking out the sky above Lin Yi. "What a massive cluster of black stones, it looks like a giant mine pit." Lin Yi surveyed the stone chamber in front of him and secretly marveled. This giant mine pit was over a hundred feet wide and five to six hundred feet tall, plunging down hundreds of feet deep, appearing extremely vast. Putting his hand on the wall of the mine pit, Lin Yi felt the stone was ice-cold and incredibly hard, worthy of being a huge mine pit. Lin Yi circulated the Mysterious Technique within his body, and immediately streams of purple gold thunder surged out, intertwining before him to form a purple gold thunder net. "Rumble!" The purple gold thunder net covered the entire mine pit, instantly encompassing everything within it, causing the stone walls to be covered with thick thunder snakes. Under Lin Yi's control, the purple gold thunder net swiftly contracted, collecting all the black stones, but he was unable to fit them all into the Purple Gold Gourd. Instead, they were trapped outside the Purple Gold Gourd. "Phew, it's a good thing I refined the Purple Gold Gourd into a sacred treasure, otherwise, I wouldn't be able to take these black stones!" Lin Yi breathed a sigh of relief, thinking to himself. "Since this mine is so huge and the black stones inside are extremely sturdy, I might as well use this place to cultivate inside!" Determined, Lin Yi sat down cross-legged, his feet hovering in the void, running the Cultivation Technique, absorbing the thunderous forces from heaven and earth, tempering his physical body. Lin Yi's body, after being tempered by the Purple Gold Thunder, had become incredibly tough, his physical body incredibly strong to the extreme, on par with a Cultivator at the Seventh Layer of the Divine Origin Realm. Lin Yi's True Yuan surged wildly, wreaking havoc within his body like a vast ocean, with waves of immense power sweeping through his entire body.
