After studying this "Shallow Reading of the Fundamentals of the Dan Dao" for a few days, Zhen Yinjian found that since he obtained the bloodline of the Immortal Body of the God Emperor, his memory has become better and better, and this brick-thick book was memorized by him in just half a day, and he also felt some things about the principles of alchemy more clearly.

The next day, knowing that he was already familiar with the refining process of "Returning Spring Pill", he got into his room and began to refine the first furnace of pills in his life.

Boom......

I only heard a loud noise, and Zhen Yinjian escaped from his house with a black face, and came out with a puff of black smoke. With a charcoal black face, his face was bitter at this time.

This alchemy was really not a simple errand, and Zhen Yinjian soon found that his first furnace of pills was broken.

"It's okay, what we have is time and materials. Zhen Yinjian continued to walk into the room with a black face.

Boom......

There was another muffled sound, and this time the door didn't open, and black smoke leaked out of the doors and windows. After a while, a "black man" rushed out and babbled at the ground.

"Damn, I don't believe in this evil, this shit is so difficult to refine. With that, Zhen Yinjian rushed in again.

In the next ten days, a large house in Zhen's Mansion unexpectedly made strange muffled noises from time to time, accompanied by black smoke and an indescribable stench. Seeing such a scene, many subordinates avoided Zhen Yinjian's residence, looking at his house for fear of avoiding it.

Just kidding, two days ago, a brave guy approached and peeked, but he didn't wake up for three days and three nights because he took a puff of black smoke!

The door creaked open, and Zhen Yinjian walked out dejectedly, he didn't expect this Returning Chun Pill to be so difficult to refine, he had been refining for ten days and still had no way to refine a qualified pill.

took out two freshly refined pills from his arms, this pill looked seven or eight points similar to the appearance of the "Returning Spring Pill" in "A Brief Reading of Dan Dao Basics", showing a black luster, and at the same time exuding a trace of medicinal fragrance, but Zhen Yinjian was still not satisfied.

You must know that the color of the "Returning Spring Pill" accumulated in this manual is much redder than the color of the jet-black pill in his hand, and the medicinal fragrance will never be so small, this pill can only be regarded as a semi-finished product at most.

"Oh my God, why is alchemy so difficult!" Zhen Yinjian wailed helplessly.

You must know that in order to refine this so-called Huanchun Pill, he has consumed all the medicinal materials worth five thousand taels of silver, and he has obtained the two slightly better semi-finished products in front of him. The cost of alchemy was so great that it simply frightened him.

This is still the lowest, unproducted elixir. If it is a high-grade elixir with complex medicinal properties and hundreds of medicinal species, wouldn't it be even more difficult. Thinking of this, Zhen Yinjian's scalp felt numb.

Sitting on the ground, looking at the slowly discarded pills in the room, Zhen Yinjian grabbed his chicken nest and felt worried. Now that Hua Guang has borrowed the money from the sect elders, he can't successfully refine the Returning Chun Pill, how can this be good.

He didn't have much spare money anymore, and the sect elders probably wouldn't lend him any more money, and he originally planned to use the craft of alchemy to earn money to continue learning the new Dan formula, but at this moment he was at an impasse.

How is this good?

"Wait, I seem to remember that the space-time secret technique of the system exchange library can practice the exercises and temper the Dan Dao through time acceleration?"

At the end of his life, Zhen Yinjian suddenly thought that he still had a system. Thinking of this, he happily slapped his thigh and did what he said.

Then Zhen Yinjian sank his consciousness into his mind, and he once again saw the strange peach heart of this and that strongest peach luck system. Then his magic sense entered the exchange library, and sure enough, he saw that the "Secret Art of Time and Space" had this function.

"Dan Array Exercise", this function is just a function set up for those who want to practice the operation proficiency of pills and formations, and its function is that the trainer can use this space-time secret technique to practice Dan Dao and formation infinitely, and the materials consumed in each alchemy and Ming Array will be restored indefinitely.

With such a strong function, of course, the price is not the same, and the cost in the Dan Array Exercise Time and Space Secret Technique is twice as much as the Communication Martial Arts Exercise, that is, 200 conquest points can be exchanged for a year of free practice of alchemy.

Quickly spent 200 conquest points, Zhen Yinjian's magic knowledge instantly placed himself in the system space, in a starry space created by the secret art of time and space, he saw the Dan furnace and medicinal materials used in his previous alchemy, and practiced alchemy little by little, which is extremely time-consuming and cost-intensive.

Fortunately, just like the martial arts exercise, he who practiced the Dan Dao in the Dan Array exercise did not feel any mental exhaustion, which was also the magic of this space.

When Zhen Yinjian's legal knowledge came out of the system space, the real time was only a few breaths away. He was very satisfied with the effect of this alchemy exercise.

First of all, after a year of sleepless and tireless practice, he finally found the technique of refining the Returning Spring Pill, and the current success rate of refining this mortal pill is more than ninety percent of five, and there is a twenty percent chance of refining a high-quality Returning Spring Pill that surpasses the record of the Dan Book.

Why is the quality of this Chun Pill high? Because he felt that the pill he had refined would emit a fragrant pill that had been fragrant for ten miles, and the intensity of the medicinal effect was even greater than that of the Chun Pill he had refined before. He didn't know what the level of this high-quality elixir was. For this reason, he planned to inquire about the drugstore.

Well, now that he knows the refining method of this Chun Dan, then he has to speed up the progress and quickly refine a batch. When he came to the market again, he found the same pharmacy where he had bought medicine.

"Boss, continue to buy me two thousand taels of Chun Dan medicinal materials, you know the proportion, hurry up." Zhen Yinjian walked into an antique pharmacy and knocked on the table.

"Ouch, guest officer, you're here again, the batch of medicinal materials you bought last time has run out?" a guy wearing a square cloth turban greeted him.

"Yes, yes, hurry up, uncle, I still have to go back to alchemy. Zhen Yinjian buckled the table impatiently.

"Okay, wait a minute, I'll bring it to you from the back hall right away. Although the man in front of him didn't know why the man in front of him had a great demand for the medicinal materials of this Returning Chun Dan, he still didn't ask too much and did it.

No one is going to be reluctant to get paid to their door.

"What an arrogant boy, is this a hairy boy like you who can refine Chundan?" A sharp voice came in, and I saw a slender old man in green clothes with a goatee walking in.

As soon as he entered the room, he glanced at Zhen Yinjian contemptuously, and his eyes rolled up.

"Young people are not afraid of flashing their tongues, although Huanchun Pill is a mortal pill, it is not something that a young boy like you can watch. ”

As soon as the old man entered the room, he found a rattan chair and sat down with a big grin.

"Shopkeeper Tong, what kind of wind is blowing you!" seemed to hear a voice, and a man with a noble and rich face, walked out and smiled at the old man with a goatee.

"Lao Wang, why don't I come to your side to discuss the purchase of a batch of silver leaf grass, those Danshi masters want a lot this month, I know you must have a surplus here, don't bother you." The old man stroked his beard and shook his head with a smile.

"Okay, since it's what the shopkeeper Tong ordered, we have to help. Who doesn't know that you are the largest medicine shop in our city, and you are a big man who can deal with Danshi. The shopkeeper of the pharmacy couldn't open his eyes when he smiled.

"After that, Lao Wang, you are sensible, and your benefits will be indispensable in the future. In the face of the praise of the king's shopkeeper, this old man was only a little humble and useful.

"Young man, did you hear what I just said? Seeing that the shopkeeper Wang went to get the medicine, the old man tilted his head and looked at himself, his eyes were not good.

"I don't understand what you're saying, so it's hard to talk too much. Zhen Yinjian said with a dry laugh.

"I don't understand, aren't you a fool? I'll give you a few words when I see that you are kind. Don't waste your efforts, I don't think you kid looks like you have a teacher, so don't expect to rely on the third-rate Dan books in the market to learn alchemy. The old man took a sip of tea.

"This is interesting, why can't I refine the Dan while others can refine it?" was repeatedly looked down upon by this old man, and he had already developed a bit of anger.

"I said you can't refine it, so you can't practice it. In terms of looking at people's eyes, I am someone in this Ningcheng, dare to say second, no one dares to say first. You don't inquire about the reputation of my Xingchun Fang. The kid is pointless, it's ridiculous. ”

The old man with a goatee sneered, crossed Erlang's legs, and poured a teapot into his mouth.

"That's interesting, why don't we make a bet, just bet that I can practice to return the spring pill. Zhen Yinjian's face was cold.

"Haha, little ghost, you send me money. Okay, old man, I'll bet. If you can refine the Spring Pill within seven days, you are willing to collect it at twice the price. As much as you have, I will collect as much as you want, let's Xingchun Fangfang. ”

The old man put down the teapot and pressed it on the table with one palm, his eyes shining.

"But if you can't refine it, you'll have to pay me 100,000 taels of silver. ”

"Okay, that's it, see you in seven days" Zhen Yinjian clapped his hands and smiled.

"Man, bring me five thousand taels of Chun Dan medicinal materials, I want it soon!" Zhen Yinjian turned around and shouted to the back room.

The old man with the goatee did not move, and waited for the shopkeeper Wang to carry all the medicinal materials into the car and send them away, and then left.

"Young man, alas, I really don't know what to say about you. Shopkeeper Wang shook his head at Zhen Yinjian, handed him a large bag of medicinal materials for Huanchun Dan, and turned to leave.

He already regarded Zhen Yinjian as a rich kid who was self-willed.

After leaving the pharmacy, he was happy in his heart at this time, how did this old man know that he had a system to cheat and complete tasks that ordinary people could not reach. This old boy despises himself so much, he will have to "repay" him well.

Thinking of the sad appearance of the shopkeeper Tong, Zhen Yinjian smiled not to mention how bad it was.
