I am grinding experience in another world

Several days later, Chen Mu lay in a rocking chair under a large tree in the Divine Statue Cave Heaven. His right hand slowly opened and closed, lightning flickered continuously, yet his eyes were fixated on the gray wall in front of him. Truthful Listening Technique: 9931/10000/Eighth Rank; Giant Spirit Divine: 7456/10000/Sixth Rank; Kui Water Yin Thunder: 9841/10000/Third Rank; Spiritual Treasure Pivot Scripture: 3125/10000/Sixth Rank; Ghost Channeling Spell: 9306/10000; Dark Cloud True Method: 3409/10000/First Rank; "The Truthful Listening Technique is quite an unexpected joy," Chen Mu thought with a chuckle. He hadn't been cultivating it deliberately, but through frequent use over time, it had almost progressed to the next stage. "The Giant Spirit Divine isn't bad either, steadily moving forward." He initially cultivated the Giant Spirit Divine to dispose of the excess vital energy from the Replenishing Origin Soup. However, given its strong power-boosting effect, Chen Mu never gave up cultivating this secret technique. "Kui Water Yin Thunder is about to progress, I can allocate more time to it in the coming days," Chen Mu pondered. He had always envied Sun Jian, who was once rampant on Jilong Road because of it. "As for the Spiritual Treasure Pivot Scripture, I can only rely on accumulating experience over time." He once had high hopes for the Spiritual Treasure Pivot Scripture to find a way out of trouble, dedicating much effort to its cultivation. But now that he had escaped the dojo with the help of the Heavenly Demon Spirit Seed, considering his Heavenly Demon Body was still confined to the Divine Statue Cave Heaven, he hadn't completely stopped cultivating it, but he had indeed reduced the time spent on it. "On the other hand, I can spend more time on the Ghost Channeling Spell recently," Chen Mu pondered while stroking his chin, "The Netherworld Ghost Patterns are quite interesting, and since it's about to reach perfection, I can first take it to the limit." Chen Mu's gaze finally landed on the Dark Cloud True Method. "This is the current focus of my cultivation." This secret technique was crucial for his Divine Orifice Refinement and the Fourth Rank of a Qi Cultivator, and he dared not neglect it. After briefly calculating his daily cultivation schedule, Chen Mu flipped his wrist, and the Five Ghosts Bag appeared. He took a deep breath, slowly opened the drawstring of the Five Ghosts Bag, and carefully watched the opening. Several strands of hair-like black streams quickly flew out of the Five Ghosts Bag, beginning to slowly disperse as soon as they touched the external air. He immediately reached out, enveloping them with the power of the Dark Cloud True Method. Whoosh! The black lines vanished into thin air. Chen Mu's spirit instantly sank into the Jade Seed, and seeing a corner of the Dark Cloud Talisman blackened, a smile appeared on his face. "Success!" He couldn't help but punch the air. In the past seven to eight days, he had scoured the five counties surrounding Luandu County. With the help of the Temple Priests like Li Buxian and their dreams in the calabash, he successfully collected a hundred ghosts and placed them into the Five Ghosts Bag. After several attempts, he finally confirmed that Ghosts paired with the Five Ghosts Bag could indeed produce Mixed Primordial Qi. "What's more wonderful is that the Five Ghosts Bag can automatically collect and store Mixed Primordial Qi, ensuring it doesn't disperse." He had experimented with the Exquisite Jade Plate and found that Mixed Primordial Qi was extremely unstable. In its natural state, it dissipated very easily -- from materialization to complete disappearance, it might last only a few dozen breaths at most. The Exquisite Jade Plate could produce eight or nine portions of Primordial Energy per day, but this required his undivided attention for the entire day. However, the Five Ghosts Bag could collect and store it automatically, preventing the Primordial Energy from dispersing. Thus, he only needed to open the bag periodically each day to harvest the Mixed Primordial Qi, saving him a great deal of time. "The ancient Thousand Mountains Path is something special," Chen Mu exclaimed with admiration. The Five Ghosts Bag, derived from the Thousand Mountains Sutra and hailing from the frontier wilderness of the Great Beam, had been with him for over a decade. Secret techniques like Five Ghosts Possession and Five Ghosts Moving Mountain remained just as powerful as ever. Now, with the added ability to produce Mixed Primordial Qi, it had once again been a great help. "Although I don't know the underlying principle, it doesn't impede my use of it for cultivation." "It's just that producing only five or six strands of Mixed Primordial Qi daily is a bit too little. I need to collect more ghosts and put them into the Five Ghosts Bag." "Mmm... I can only burden Li Buxian a bit more. Haha!" Li Buxian: "..." ... The weather grew increasingly hot, and more than a month sped by. Luandu County entered the rainy season, with light rains falling every few days. Under the gate tower of the Divine Statue Cave Heaven, Chen Mu closed his eyes, comfortably lying on a rocking chair gently swaying. The water screen in front of the gate displayed scenes of the surrounding Jade Belt River, and the sound of raindrops falling into the river lingered constantly in Chen Mu's ears. After a while, he slowly opened his eyes and stretched his limbs and hands fully, feeling completely relaxed all over. During this past period, besides going out daily to accept Ghosts collected by Li Buxian and others, he spent most of his time lying inside the grotto heaven cultivating, with remarkable results. With a thought, a gray wall materialized before him. Truthful Listening Technique: 231/10000/Ninth Rank; Kui Water Yin Thunder: 1731/10000/Fourth Rank; Ghost Channeling Spell: Limit; Dark Cloud True Method: 89/10000/Second Rank; Progressing in the Truthful Listening Technique expanded his detection range, enhancing his probing capabilities. Advancing to the Fourth Rank of Kui Water Yin Thunder, its power became quite impressive, already comparable to Sun Jian back on Jilong Road. The Ghost Channeling Technique reached Perfection, allowing him to enter and exit the Nine Serenities Abyss at will, no longer being forcibly ejected by countless Ghost Patterns like in the beginning. Most importantly, he finally maxed out the First Rank of the Dark Cloud True Method. "It's also time to start refining my Divine Orifice," Chen Mu was excited within. Over the past month, he had accumulated four to five hundred yin souls in the Five Ghosts Bag, able to provide more than forty strands of Mixed Primordial Qi each day. The Dark Cloud Talisman had turned completely pitch-black four or five days earlier. This represented an abundance of Mixed Primordial Qi, ready for Divine Orifice refinement. The reason for waiting until today was to ensure the First Rank of the Dark Cloud True Method was perfected. Meticulously perceiving the feedback from the gray wall, a hint of realization flashed in Chen Mu's eyes: "Indeed, there is some trick to it." The Mixed Primordial Qi possessed formidable erosive power; if not careful during the Divine Orifice refinement process, it could potentially damage the very essence of the Divine Orifice. With the perfection of the First Rank of the Dark Cloud True Method, a capability called 'Mutual Annihilation' emerged. With it, if the Divine Orifice suffered excessive corrosion, Chen Mu could induce the Mixed Primordial Qi to dissipate, halting the refinement process in time to ensure the safety of his cultivation. After going over the key information for Divine Orifice refinement one last time, Chen Mu took a deep breath and immersed his spirit into the Jade Seed. At that moment, the pitch-black dark clouds swirling around the Divine Orifice flickered with light, resembling lightning. The next instant, the dark mist surged and dispersed with a hum. Then transformed into nine black dragon-shaped tornados, drilling into the Divine Orifice from all sides, rapidly expanding through the gaps between the Divine Orifice Talismans. At a certain Divine Orifice node, a dense network of interconnected Talismans formed a massive web. Like black smoke, Dark Cloud Talismans flew along the gaps and lightly collided with a root-like Divine Orifice branch. Hiss! Like acid corrosion, tiny pits appeared on the root-shaped Talisman instantly. In the blink of an eye, the firm and shiny-metallic Talismans were eaten away without resistance, creating a large corroded depression. Just as the root-shaped Talisman was about to corrode away completely, the black fog suddenly halted, then dissipated into tiny luminescent sparks. In no time, white mist-like Mana was drawn forth, and the riddled Divine Orifice Talisman started to slowly regenerate, fully restoring in short order. But upon closer inspection, one could see invisible black threads within the root-like Divine Orifice Talisman, similar to the veins in a leaf. It was these black lines that imparted the Talisman with a different kind of toughness. Hiss, hiss, hiss... The Divine Orifice trembled faintly, and similar scenes unfolded throughout the entire tier-nine Divine Orifice. As the Divine Orifice Talisman corroded and then regenerated, they gradually evolved amidst this cycle of destruction and repair. Waves of pain and numbness flowed continuously from the depths of Chen Mu's soul. The sensation wasn't intense, but it was persistent. With no way to scratch it or reduce it, he could only endure slowly. Immersing himself in cultivation like this, he practiced for an entire day. By the time Chen Mu completely concluded this first Divine Orifice refinement, it was already evening. The previous numbness and pain were gone, replaced by a feeling of refreshed clarity. The entire Divine Orifice Talisman also held an added sense of deep, peaceful mystery. "This path is indeed open now," Chen Mu couldn't help but smile. "With the Five Ghosts Bag and the Ghosts, even if Yunzhou's geomantic veining changes and the Buried Spiritual Springs disappear, it won't affect my Divine Orifice Refinement!"
