"Throughout the generations, Beast Tamers could only do their best to artificially cultivate some, more easily propagated, more easily farmed, and also more affordable types of spatial silkworms." "Some exceptionally talented Artifact Refiners also continuously improved the methods of refining Storage Bags, hoping to enable the majority of cultivators in the Cultivation World to use Storage Bags." "Green Void Silkworms are so far the most suitable type of spatial silkworms cultivated by cultivators." "The threads of the Green Void Silkworm are inexpensive and very durable, although the space is slightly small." "Today, in the Cultivation World, over eighty percent of the Storage Bags are woven from the threads of the Green Void Silkworm." "There are also some silkworm types that are even more precious than the Green Void Silkworm." "However, these types of silkworms, when they spin their threads into Storage Bags, make the price much higher, not affordable for the average cultivator." "As for the more precious, ancient ones, like the Golden Void Silkworm, Star Void Silkworm..." Gu Changhuai sighed, somewhat regretfully. "...These types of silkworms have always been rare in reproduction and, over tens of thousands of years, due to the frantic scrambling and hunting by cultivators, most are now endangered, even extinct..." "The few that have survived either become the 'forbidden delicacies' of the Central Dao Court, or that of local influential families or Great Sects." "Or they hide in the secret spaces of some Ancient Daoist sites, abyss forbidden lands, the ultimate extremes of heaven and earth, unknown to people." ... Gu Changhuai had explained the origins of the Storage Spiritual Artifacts. Mo Hua couldn't help but be enlightened. He hadn't expected that the Storage Bags, commonplace in their daily use, would contain so many secrets. What seemed like ordinary Storage Bags were the crystallization of tens of thousands of years, countless cultivators' heart's blood, and the development and evolution of various Dao cultivation skills. What seemed like ordinary objects contained broad and profound truths. Mo Hua spaced out in amazement, meanwhile feeling moved. Hollow Void Realm, the power of space. Fifth grade spatial Formation... He wondered when he would be able to cultivate to the Hollow Void, to learn the fifth-grade Formation... Mo Hua heaved a sigh, and after spacing out for a moment, he remembered that the matter of the Fire Buddha was more urgent. Since it wasn't teleportation... that would be easier to handle. Under the restrictions of the Second Grade law, the abilities that a cultivator could use were quite limited. Mo Hua, being a Formation Master, and moreover, a knowledgeable one, was very clear about the various capabilities of Second Grade cultivators and the Dao laws. Mo Hua pondered and said: "It hasn't truly disappeared, it's not teleportation, which means it's just become invisible..." "Being invisible also means they have turned invisible." "It might not necessarily be a Concealment Technique; it is very likely a spiritual artifact used for concealment, most likely a Concealment Formation..." "The Fire Buddha and his group wiped out the Xie family, then used a Concealment Formation to disappear from the blaze, hiding somewhere unknown..." "And those eight characters on this Letter Token, 'Bi Mountain Demon Cavern, Heaven Outside Heaven,' are very likely the hiding place and code of this group of Sin Cultivators..." "Bishan City is an Immortal City, crowded and bustling; it's not the place Demon Cultivators could normally hide." "But if there really is a Demon's Cave, then this Demon's Cave is likely concealed by a Concealment Formation..." "Bishan City has intersecting peaks and complex terrain..." "To build a Demon's Cave and hide it with a Concealment Formation, ordinary cultivators really might not be able to find it..." "And one more phrase, 'Heaven Outside Heaven'..." "That means the cliffs and precipitous, secluded steep places within the city, are very likely the location of the Demon's Cave." "Heaven, might refer to 'a thin thread of sky'..." "The places known as 'a thin thread of sky' may have some pathways hidden by the Concealment Formation, akin to 'Heavenly Roads'; beyond these Heavenly Roads, there lie other Heavens..." ... Mo Hua articulated his thoughts clearly, speaking smoothly. Gu Changhuai was somewhat astonished. This child was indeed too clever. Not only was he quick-thinking, but he also had deep knowledge of Formations, and even these odd "experiences" seemed extensive... As if he had been dealing with Sin Cultivators and Evil Cultivators for years... Knowing how they acted, how they hid. Something was not quite right. Gu Changhuai hesitated for a moment, puzzled, he asked: "How do you know so much?" Mo Hua didn't hide it, replying, "I've seen it, so I have a deep impression." "Seen?" Gu Changhuai was puzzled. "Yes," Mo Hua nodded, "Back when I was in Tongxian City, working as a Monster Hunter..." "The Sin Cultivators in Big Black Mountain were using Concealment Formations to hide the roads leading to the back mountain; then, using heavy fog as cover, they committed murder and robbery, misdeeds and crimes..." "I've also seen some Evil Cultivators build strongholds behind 'a thin thread of sky' to refine corpses, like Corpse Palaces and such..." Gu Changhuai frowned, "Aren't you a Formation Master? Since when have you also been a Monster Hunter?" Mo Hua replied, "My father was a Monster Hunter, so naturally, I followed in his footsteps, what's so strange about that? It's a family trade, can't let it vanish..." "But I was naturally frail; not really good at monster hunting, so I had to find other alternatives..." "Besides being a Monster Hunter, also a Formation Master and an exter Description: "A person who is described as having a sophisticated allure, often due to a striking or unconventional appearance. Demeanor: "A person who is described as having a sophisticated allure, often due to a striking or unconventional appearance. Demeanor: "A person who is described as having a sophisticated allure, often due to a striking or unconventional appearance. "... Mo Hua sighed, a resigned expression on his face, "Can't help it, grew up poor, so inevitably I had to endure some hardships, had to do a bit of everything..." Gu Changhuai looked at his delicate, tender face and occasionally brazen demeanor, not believing for a second that he had suffered any "hardships"... But... "Your mere decade or so of life, it's still quite rich..." Gu Changhuai said. Again being a Monster Hunter, again those Sin Cultivators in the back mountain committing murder and robbery, again those mountain stronghold Corpse Cultivators and such...
