The Dan Lou occupied an extremely large area. After all, it was a top force in the Rainwave City’s alchemy industry. Although its geographical location was not as good as Luo Feng’s cave, its area was hundreds of times larger.

Within the Dan Lou, there were more than a hundred buildings of varying sizes. The largest was the main building, which was open to the public and served as the primary place for selling pills.

Many of the other buildings were residences and alchemy workshops for the alchemists.

“Buzz.” Luo Feng was in the main building, sensing the formation of the entire massive Dan Lou complex. Lou Master Changqing did not stop him, allowing Luo Feng to perceive the detailed formations of the Dan Lou.

“The current formations of the Dan Lou are mainly suitable for me,” Lou Master Changqing said. “Brother Luo Feng, see how to arrange formations suitable for you, and feel free to mention which formation materials need to be purchased. No need to save on expenses.” Fixed formations were generally much more powerful than mobile formations.

“Mm,” Luo Feng studied for a moment and then sent a list of formation materials to Lou Master Changqing via message. “Lou Master, the estimated price of this list of formation materials is around 30 million Origin Crystals,” Luo Feng said.

“Good, good, good!” Lou Master Changqing revealed a look of joy. “I was afraid it wouldn’t be expensive enough. I will immediately arrange for a clone to purchase the materials.”

Luo Feng was quite satisfied with Lou Master Changqing’s character. One of the reasons he chose the Dan Lou was that Lou Master Changqing had a very good reputation. Before long, Lou Master Changqing bought back the formation materials. “Brother Luo Feng, it’s up to you.” Lou Master Changqing gave the formation materials to Luo Feng, who nodded slightly as he looked at them.

With his architectural vision, he could design the most suitable fixed grand formation for himself. This fixed grand formation had a total of 36 formations working together. Since they were all fixed formations, the average cost per formation was nearly a million Origin Crystals.

Rumble!

Luo Feng hovered in the center of the Dan Lou complex, controlling numerous formation materials, and began to arrange them one by one. Setting up formations was like building a spaceship. Like a spaceship, there was a system responsible for stabilizing the hull, one for speed, one for power, and one for exploration. Various systems working together made up a spaceship.

Luo Feng’s formation arrangement was much more complex. The formations he purchased were of the life-and-death combination type in Rainwave City. The limits of the formations even exceeded his current control limits.

These 36 types of formations were all of the half-Origin level, with profound mysteries. Moreover, the half-Origin life paths comprehended by different cultivators were different from each other. Therefore, it was even more difficult for Luo Feng to activate them. His current strength could only unleash 30-40% of the formation’s power. “It’s done,” Luo Feng spent half a day, not daring to slack off in the slightest, before completing the formation arrangement.

With a thought from Luo Feng, his mental consciousness permeated the entire grand formation, and the formation naturally began to operate. Invisible fluctuations spread around the Dan Lou complex, and the power was restrained.

“Although this fixed formation only exerts a small portion of its power, it is still much more powerful than my Profound Azure Sky Extinction Diagram, and even more powerful than the enhancement of the Undying Heart,” Luo Feng sighed inwardly. This was the advantage of fixed formations. After arranging the formation, Luo Feng flew back to the main building. “Brother Luo Feng, hard work!” Lou Master Changqing had been watching all along.

“It’s just a small matter, and I will be stationed here for a long time in the future. The stronger the formation, the safer the Dan Lou will be,” Luo Feng laughed. “By the way, Lou Master, I want to purchase a large batch of low-level Origin Life materials, on a relatively large scale. Who do you think would be suitable to buy from?”

“A relatively large scale?” Lou Master Changqing asked, “How much?”

“At least 2 billion Origin Crystals or more,” Luo Feng said. Lou Master Changqing was a little surprised when he heard this. According to the intelligence, Luo Feng had not been in Rainwave City for long, so in theory, his accumulation of wealth should not be much. However, 2 billion Origin Crystals was not easy for even some long-accumulated veterans to take out at once.

“This is a big business.” Lou Master Changqing thought for a moment, “There are 13 companies in Rainwave City that deal in low-level Origin Life materials. In my opinion, for a business of this scale, it’s better to look for Elder Xingyi. Elder Xingyi has an excellent reputation. Not to mention a business of 2 billion Origin Crystals, even if it were ten times that amount, Elder Xingyi would be trustworthy.”

Lou Master Changqing said, “This Elder Xingyi has a great background. He is a personal disciple of an invincible existence in the Dark Sacred Realm.” “An invincible existence in the Dark Sacred Realm?” Luo Feng was shocked. The Dark Sacred Realm gathered numerous meta-worlds, and only the most elite cultivators from billions of worlds dared to call themselves invincible there.

There was envy in Lou Master Changqing’s eyes, “No matter how dazzling or talented one is, they generally become mediocre in the Dark Sacred Realm. To be able to become a member of the peak level in the Dark Sacred Realm… is already extraordinary. As for being called invincible, it is also a legend in the Dark Sacred Realm. Even wanting to meet them is a luxury.”

Luo Feng held his breath.

Invincible in the Dark Sacred Realm? “Elder Xingyi is a personal disciple of such an existence,” Lou Master Changqing said. “He is absolutely honest in doing business.”

“Good.” When Luo Feng sold the corpse of the Bloodfiend Eris before, he sold it to a shop owned by Elder Xingyi. The other party gave a high price, and Luo Feng also obtained Elder Xingyi’s communication mark. Luo Feng’s cave.

Luo Feng contacted Elder Xingyi and sent him a purchase list.

After the space in front twisted, a figure appeared. He had a body like a tree, with branches growing all over his surface. Even his face had a little bit of green blossoming, and his smile was brilliant. “Brother Luo Feng, you want to purchase so many materials?” Elder Xingyi was a little surprised. “I think if you purchase a portion of low-level Origin Life bloodlines, there is no need to purchase those scattered materials.”

“I would trouble Elder Xingyi to help with the purchase according to the purchase list,” Luo Feng said.

“Good.” Elder Xingyi smiled, “This is a big business. You also know that the prices of various low-level Origin Life materials are very clear.”

Luo Feng nodded. He had sold corpses of low-level Origin Life himself and knew the other party’s costs.

“This is the lowest price I can give,” Elder Xingyi sent a price list, which Luo Feng was quite satisfied with at a glance.

“Elder Xingyi is indeed honest. Let’s settle on this then,” Luo Feng said. “Good.” Elder Xingyi revealed a look of joy when he heard this, “Many of the materials you are purchasing are relatively rare. Even if the Nine United Holy Realm and 35 cities purchase them comprehensively, it will be a little troublesome. I will send some materials from the Dark Sacred Realm. We estimate that we will trade three days later.”

“Do I need to pay a deposit?” Luo Feng asked.

“No need,” Elder Xingyi said nonchalantly, “I will go to your cave in three days.”

“Good, let’s do as Elder Xingyi says,” Luo Feng nodded. Three days later.

Elder Xingyi came to Luo Feng’s cave.

Elder Xingyi wore a loose robe, under which his bark-like body was revealed, and some sap grew on his head. His smile was filled with endless vitality. Luo Feng couldn’t help but feel a sense of goodwill.

“Brother Luo Feng, please take a look.” Elder Xingyi took out a spatial bracelet and allowed Luo Feng to check it.

With a thought, Luo Feng checked and saw many low-level Origin Life materials, as well as complete Origin bloodlines, each of which was preserved very carefully. Luo Feng slightly sensed these bloodlines and determined their level, knowing their approximate mysteries.

“That’s right,” Luo Feng also took out a cloth bag, “2.83 billion Origin Crystals.” This was Luo Feng’s most extravagant purchase.

“Brother Luo Feng, if you want to purchase ultra-limited bloodlines in the future, you can also contact me at any time,” Elder Xingyi laughed, “I can also purchase them for you from the Dark Sacred Realm if the Nine United Holy Realm doesn’t have them.”

“It’s really too expensive, let’s wait for the future,” Luo Feng said with emotion. After obtaining the 5 billion Origin Crystals from Hall Master Yuanxiang, Luo Feng could also start purchasing lavishly, but he still couldn’t buy whatever he wanted. He still had to pursue cost-effectiveness and efficiency.

Luo Feng purchased a batch from Elder Xingyi, bought various auxiliary cultivation medicines worth 500 million Origin Crystals from the Dan Lou, prepared some gifts for his master Emperor Chu and Mountain Guest and City Lord of Chaos, and then quietly left Rainwave City.

Since the items he was carrying were too valuable, Luo Feng naturally carried the Undying Heart and quietly left Rainwave City in the palm of his hand. Luo Feng returned to the Origin Continent again, inside the Star Tower.

Rumble!

Numerous purchased materials and items were all released. Luo Feng’s eyebrows opened the Eye of Life and Death. Under the observation of the Eye of Life and Death, which was comparable to a high-level Origin Life, the deep-level mysteries of each material and bloodline could be spied.

“This is a God Emperor Early Stage clansman of the low-level Origin Life Nirvana Fire Serpent clan.” Luo Feng looked at the fifteen kinds of scattered materials in front of him, including teeth, scales, bones, and membranes. “I have been comprehending him for a long time. By observing these fifteen materials with the Eye of Life and Death, I have thoroughly studied the various mysteries possessed by the Nirvana Fire Serpent clan in the God Emperor Early Stage, and I have already completed them in my heart.” Luo Feng looked at a piece of jade that contained a bloodline burning with black flames.

“This is a refined complete bloodline of the Nirvana Fire Serpent clan in the God Emperor Early Stage. A complete bloodline contains all the mysteries.”

Luo Feng was quite looking forward to it, “Now let’s see how different the mysteries I have completed in my heart are from the complete bloodline.” In the past, he had been using a poor purchasing method, buying small pieces here and there, comprehending the mysteries from the small pieces, and finally completing them in his heart, combining them into a complete mystery as a whole.

Luo Feng’s Eye of Life and Death observed this bloodline burning with black flames.

Luo Feng was slightly stunned, “The mysteries I have completed in my heart are too rough, this is the true perfection.”

Luo Feng learned a lot. He observed more than a dozen kinds of scattered materials with the Eye of Life and Death, studied them carefully, and completed them in his heart, just like doing a problem. A complete bloodline, on the other hand, was the most perfect answer naturally conceived by the infinite Origin space.

After completing the problem, Luo Feng understood the difference after comparing it with the answer, “Life and destruction can be combined like this? I learned something.” Luo Feng was delighted in his heart. He carefully experienced the methods of combining these mysteries. Although it was just a low-level Origin Life bloodline of the God Emperor Early Stage, it was still a great gain for Luo Feng at this moment. After all, these were existences born to break free from the cage. (End of this chapter)
