Chapter 516: Alchemy Formulas

After waiting for half an hour, the delivery door creaked open, and Yun Lan stepped out.
Not only Lin Dong but also Old Ding and Feng Yue were shocked. They had all personally tested this large box, which made them even more curious about what was inside. After all, if their lifespans ever came to an end, even if they wanted to leave something for future generations, they would not go to such lengths. At most, they would find an uninhabited cave—those who understood arrays would set up a few, while those who didn’t would create simple traps, then dig a hole and place some valuable items on top. Better items, such as spiritual skill pills, would be stored inside the cave. Opening such a hole might require kneeling or stepping on a certain spot—there was no need to go through such trouble and spend a huge amount of effort collecting so many materials for a box whose method of creation wasn’t even known to senior alchemists with a long history.
Although the materials for dissolution were common and easy to obtain, there weren’t many alchemy schools with a long history. Even if the truth were spread, few would know the origin of this large box.
“Girl Yun, hurry up and open it,” Old Ding urged impatiently after gulping down a mouthful of fine wine.
“Old man, you might be disappointed!” Yun Lan laughed. “The materials are here, but we still need to wait for the medicinal liquid to be boiled. If I remember correctly, it should take three hours—any more or less and the effect won’t be good.”
“Is it that troublesome?”
Not only was Old Ding disappointed, but Lin Dong and Feng Yue also looked disappointed.
Yun Lan smiled, took out the alchemy furnace and special wood used for alchemy, and lit it.
A fierce fire ignited at the bottom of the furnace, and soon, a strange aroma began to spread from the large furnace. Yun Lan poured bucket after bucket of water into it until the entire furnace was filled with water.
In moments, the water inside began to boil rapidly.
After some of the water evaporated, Yun Lan slowly added the three types of fifth-tier spiritual materials in equal proportions.
Then, she sat cross-legged outside the furnace, pouring her spiritual energy into it. Instantly, the already scorching flames flared even more, emitting light as bright as the sun. The boiling water and the three types of fifth-tier spiritual materials also churned more violently.
As Yun Lan’s spiritual energy continued to fuel the flames, the boiling water kept evaporating and gradually merged with the three types of spiritual materials.
“Add more water!”
Seeing that the water level was low, Yun Lan spoke up.

Lin Dong quickly took out the jars of clean water kept in the mobile counter. Under the control of the Yu Tian Jue, he sent this water into the alchemy furnace. Inside the furnace, the water level kept dropping, and Lin Dong kept adding more water. The fragrance of the herbs spreading around grew increasingly strong. After more than twenty times, the flame beneath the furnace suddenly dimmed, clearly due to the weakening spiritual energy supplied by Yun Lan. Just as Lin Dong thought Yun Lan had exhausted too much spiritual energy and was about to ask if he needed help, the blue liquid inside the furnace began to spin rapidly. The speed of rotation grew faster and faster until it suddenly stopped. Beneath the furnace, the wood had already gone out. Looking inside the alchemy furnace, the blue liquid had lost 90% of its water content due to the rapid rotation, turning into a sticky mass of solution. “It’s done!” Yun Lan stood up and said, “Elder Feng, you’re in charge of filling the area around the box with moisture and staying alert for any emergencies. Old Man Ding, you’re responsible for pushing the Qian Huan Dan aside as the box dissolves. Lin Dong, you’re in charge of pouring the solution.” All three nodded. Lin Dong eagerly used the Yu Tian Jue to lift the alchemy furnace. Feng Yue pushed with his right hand, causing mist to gather from all directions and spray around the box. “It’s ready!” When the alchemy furnace reached above the box, Lin Dong gave a reminder. He quickly activated the cellar’s properties, setting the area around the box to dozens of degrees below zero, then paused at this final step. Taking a deep breath, Lin Dong directed the alchemy furnace to tilt slowly, causing the blue solution at the bottom to flow downward and splash onto the box. Old Man Ding focused his gaze on the spot where the blue solution began to soften and collapse, then controlled it to spread outward. It was as if a small hole opened in the center of the box, which then started to tear outward. Feng Yue watched intently, his eyes blazing, staying fully alert as the gap continued to expand. “Huh!” Suddenly, Feng Yue let out a soft exclamation. Even without his reminder, Lin Dong and the others were still focused on the box. Though their attention wasn’t as concentrated on the gap as Feng Yue’s, it was only by a fraction of a second. Inside the box were rows of brand-new books. By the time the box was completely dissolved and pushed aside by Old Man Ding using the Yu Tian Jue, inside were stacks of ancient books.

“Could it be some spiritual technique?” Old Ding and Feng Yue both looked disappointed. Spiritual techniques held no appeal for them anymore. At their current level, what truly interested them were only some rare and exotic spiritual materials and beasts. And even those could only satisfy their curiosity to a degree.

Lin Dong waved his right hand, and a book from the top right corner flew into his hands. Looking down, it had a dark blue cover. Right at the top of the cover were several large characters written in brushstroke: “Trauma Chapter (1)!”

Lin Dong was also disappointed. He could imagine that the book would likely discuss types of injuries and what spiritual or medicinal materials could be used to cure them. Opening the first page, as he expected, it contained a table of contents related to injuries. A few more pages later, there were formulas and descriptions for crafting related pills. The only thing that surprised Lin Dong slightly was that all the illustrations in the table of contents were hand-drawn.

With a wry smile, Lin Dong handed the book to Yun Lan. “It’s a pill-making formula.”

Yun Lan clearly understood Lin Dong’s disappointment. After taking the book, she reminded him, “Just that chest alone is already a huge gain. If this chest was made by the owner of these books, there might even be formulas for the Thousand Illusion Pill inside.”

Lin Dong was stunned, his mood improving significantly. Indeed, although he had high hopes for what was inside, disappointment aside, just that chest was already extremely valuable, so there was no need to worry too much.

“Since the old man and Senior Feng are both here, why not take the Thousand Illusion Pill now? Ask them to help refine it,” Yun Lan said with a smile. “If these books happen to be worth studying, maybe you’ll be able to catch up to me for the first time and reach the eighth level of the Heart Reversal stage.”

Lin Dong chuckled and immediately headed over to the Thousand Illusion Pill collected by Old Ding. Surpassing Yun Lan was also one of his goals.

“Take a dose about the size of an ordinary pill first, and then continue after refining it,” Yun Lan reminded him.

“Understood!” Lin Dong nodded. He went to the solution containing the Thousand Illusion Pill, dipped his finger in and picked up a small amount. His touch still felt nothing, but it was as soft as soft soil and could be easily shaped into a ball.

He formed a ball roughly the size of an ordinary spiritual pill. Without bothering to think about the fact that it had been around for over a thousand years, he put it in his mouth in one gulp.

With a gulp, the colorless and tasteless Thousand Illusion Pill was swallowed by Lin Dong.

“Old man, Senior Feng…” Lin Dong’s gaze shifted toward Old Ding and Feng Yue.

The two were even more disappointed than Lin Dong—at least, the Thousand Illusion Pills were of no use to them. But when Boss Lin Dong spoke, they had no choice but to reluctantly step forward. After Lin Dong sat in seiza position, each of them placed a palm on his left and right shoulders.

Once the Thousand Illusion Pills entered his stomach, they quickly reached his stomach cavity. With Lin Dong’s mental command, his spiritual energy began to leave his meridians, circled in his stomach, and then flowed back into them. Just as the spiritual energy was about to fully leave his stomach, surges of powerful energy burst forth from the pills and followed Lin Dong’s spiritual energy back into his meridians.

“Prepare to re-enter the stomach!” Old Ding shouted. Almost simultaneously with Feng Yue, he poured his spiritual energy into Lin Dong’s meridians. In an instant, they caught up with Lin Dong’s spiritual energy. The two massive streams of energy pushed Lin Dong’s spiritual energy and the energy released by the pills to surge rapidly through his meridians—faster than ten times what Lin Dong could achieve through cultivation alone.

Returning to his dantian with the energy from the pills, Lin Dong was surprised to find that all of that powerful energy had transformed into spiritual energy upon entering his dantian—and it was completely integrated with his original spiritual energy. In just one cycle, Lin Dong could sense that his spiritual energy had increased significantly.

With his strength at the seventh level of the Heart Reversal stage, he could already feel a noticeable increase in spiritual energy after just one cycle, proving the immense power of the Thousand Illusion Pills.

Without hesitation, under Lin Dong’s command, his spiritual energy quickly left his meridians, circled in his stomach, and then returned. Old Ding and Feng Yue accelerated their own spiritual energy, pushing Lin Dong’s spiritual energy and the energy from the pills to rush through his meridians before returning to his dantian.

Meanwhile, Lin Dong was completely immersed in the feeling of his spiritual energy soaring rapidly. Over and over again, he drew out the energy from the Thousand Illusion Pills and, with the help of Old Ding and Feng Yue, quickly transformed it into his own spiritual energy.

On the other side, Yun Lan had already arrived at the stack of books arranged in a rectangular formation. She flipped through them one by one, her beautiful face growing increasingly astonished.

There were many formulas in these books that she had never heard of before.

In a cultivation sect with a long history, it was already rare for an heir to come across pill formulas they had never heard of. A single book containing nearly a thousand formulas, with hundreds of them being unheard of—this was absolutely unbelievable. Moreover, there were over a hundred books in the entire box.

Tens of thousands of pill formulas she had never heard of!

Time passed by minute by minute, with sunrises and sunsets, and before long, another day had passed. Just as the Qianhuan Dan in Lin Dong’s body was about to be completely refined, Yun Lan had already turned to the last page of the final book on spirit pills for cultivation assistance. The moment she read the content of that last page, no one could imagine the extent of Yun Lan’s shock.
