The shopkeeper quickly followed the servant over. When he saw the porcelain bottles on the stone table, his eyes lit up.

He first cupped his fist in greeting towards Lin Cheng before picking up a porcelain bottle to examine the pill's appearance. Who knew that the moment he removed the stopper, a rich fragrance would be emitted from the porcelain bottle, causing him to feel refreshed.

High-grade medicinal pills!

Just the rich fragrance of the pill was enough to stir his spirits. It was easy to imagine the effects of the pill.

There were a total of thirty-five Triple Treasured Pellets. Although the shopkeeper couldn't tell which Rank of pellets it was, but just the quantity itself was already out of his expectations.

One had to know that he did not give Lin Cheng much medicinal ingredients, yet Lin Cheng only used less than half a day to refine over thirty medicinal pills. This rate of success was truly astonishing.

"This Lin Yu is indeed an apothecary, and a very capable one at that!"

The shopkeeper's heart tightened and cold sweat broke out on his back. It was fortunate that Lin Cheng was magnanimous and did not bother about his previous mistakes. Otherwise, if the management knew that he had offended such a master alchemist, he would be severely punished.

Thinking of this, the shopkeeper felt both respect and fear towards Lin City. He never thought that Lin City would actually be an alchemist at such a young age, not to mention a grandmaster alchemist at that. This made him admire Lin Cheng from the bottom of his heart. However, when he recalled that he had offended Lin City just a few hours ago, and that he had even thrown the porcelain bottles to the ground, he couldn't help but feel fear in his heart.

"Master Lin, if there is anything you need this lowly one to do, feel free to tell me." The shopkeeper gave a deep bow to Lin City, his posture extremely low.

"These Three Treasures Pill have no other effects, but at a critical moment, it should be able to help a heavily injured person to keep his life and speed up his recovery. However, refining these medicinal pills has expended a great deal of my mental and Origin Energy. I need some medicinal materials now, and I'll have to trouble you to prepare them. " Lin Cheng said.

"Master Lin, if you need any medicinal herbs, feel free to instruct me." The shopkeeper hurriedly said.

Even though Lin Cheng had said that these three treasured pellets had no other uses, and were only used to keep him alive and recover quickly, the head storekeeper didn't dare to neglect them in the slightest. No one knew if Lin Cheng would be able to refine any other medicinal pellets.

Lin Cheng immediately told the shopkeeper about the medicinal ingredients he needed. Of course, since he had only refined one pill on his first day in the shop, he did not ask for any medicinal ingredients that were too precious. Instead, he asked for a few that could be considered common medicinal ingredients according to his own needs.

Although these medicinal herbs were ordinary and could not be used to concoct any top-grade medicinal pills, Lin City was only at the fourth level of the Body Refinement Realm, and these medicinal pills could actually be used to their advantage!

On the path of cultivation, pills could provide a powerful supporting effect, but to consume pills, one had to match it with one's own strength. If a little martial artist at the level of the Manchu Realm were to directly take a supreme grade immortal pill, the terrifying spiritual energy contained within the immortal pill would be enough to cause his body to explode.

He had originally thought that Lin Cheng would want a lot of valuable medicinal materials, but he never thought that Lin City would actually want a few ordinary medicinal materials. This caused him to secretly heave a sigh of relief.

He wanted to curry favor with Lin City, and change the bad impression he had in Lin City. However, if the request from Lin City was too excessive, he would definitely feel troubled. He had no right to make decisions regarding some of the more valuable medicinal herbs.

Very quickly, the shopkeeper delivered the medicinal herbs that Lin Cheng wanted. "Master Lin, do you think that these medicinal herbs match your needs?"

Lin City only took a glance before nodding his head in satisfaction. These medicinal herbs were all very fresh. It was obvious that the medicinal properties had not been lost much yet after just picking them.

"That's right!"

Lin Cheng said, "Shopkeeper, I'll have to trouble you."

The shopkeeper was flattered and hurriedly said, "Master Chen, you are too polite. This is something I should do."

He then turned to the two servants and said, "The two of you must listen to Master Lin's instructions. Remember, the rule of my return is not a decoration."

The two servants acknowledged him immediately.

The shopkeeper was very tactful and didn't disturb Lin City too much. He quickly bade farewell and respectfully left.

Lin Cheng had expended a lot of energy to concoct the Three Treasures Pill, so he did not plan to refine it immediately. Instead, he sent two servants out and sat cross-legged on the ground to cultivate to recover his elemental energy.

Chen Yongwen frowned as he looked at the few porcelain bottles in front of him.

"These were all refined by Lin Yu?" Chen Yongwen asked.

"Master, yes." A servant in front of him replied respectfully.

"It was personally concocted by Grandmaster Lin. His name is Three Treasures Pill." Another worker followed suit.

After pondering for a moment, Chen Yongwen suddenly asked, "Did you guys clearly see how he refined it?"

The two servants were stunned for a moment before shaking their heads. "No."

Both of them were a bit nervous. Chen Yongwen had instructed them to pay attention to the process of Master Lin's pill refining, but both of them had their heads swelled up by the smell of the medicinal herbs. They couldn't even open their eyes, so they naturally didn't see the whole process.

"Go then. Next time, you should pay attention to the opportunities that have been given to you guys. Whether you can become my apprentice apothecaries will depend on your own hard work." Chen Yongwen lightly said.

The two servants were slightly startled, they were already prepared to be reprimanded, but they didn't expect that Chen Yongwen actually didn't reprimand them at all, and just let them go so easily.

"Yes sir!"

Although the two of them did not understand, they knew that it was a good thing. They quickly responded, "Thank you, Master."

Chen Yongwen slightly nodded and said, "Remember, when Master Lin forges the pill, immediately come and report to me. Go."

After the two servants left, Chen Yongwen's frown deepened.

"Strange …"

He muttered to himself, "I refined the pill according to his sequence, but it did not have this effect. It seems that the key lies in this person's pill forging skills!"

"What a strange technique …"

Chen Yongwen's hands moved subconsciously. If Lin Cheng was here, he would have definitely recognized that this was the finger technique that he used to concoct the Three-Treasured Pellet. "If I could learn this technique, my alchemy level would definitely increase by another level."

Greed flashed through his eyes as he thought in his heart: "Lin Yu, this pill refining method of yours belongs to me!"

After cultivating for a full four hours, Lin Cheng finally exited his cultivation state. Feeling the surging Yuan Power in his body, a flash of joy flashed in his eyes.

"Looks like consuming as much Yuan Power as possible can indeed help in my training."

"Every time I use up all the elemental energy in my body, it is equivalent to a purification process. The elemental energy that I will be able to cultivate will be purer and more powerful than before!"

Lin Cheng couldn't help but rejoice in his heart. In this way, alchemy and cultivation were complementary to each other.

Consuming large amounts of elemental energy to concoct pills would allow the elemental energy to be purer, while refining pills with pure elemental energy would allow the pills to be of a better quality and be more effective.

Moreover, the dan beads he made could speed up his cultivation. It could be said that killing two birds with one stone would give him twice the results with half the effort!

After four hours of cultivation, Lin City's elemental energy had completely recovered, so he started to refine the medicinal pills that he needed.

However, upon recalling the strange feeling of being spied on while he was forging the Three Treasures Pill, Lin Cheng didn't call the servants over to help him. Instead, he began to process the medicinal herbs himself.

Although he had promised Chen Yongwen that he would teach the other apprentices that would come together in his free time, the feeling of being watched made him secretly wary. If the two servants were there, he would not send them away, but if they were not, he would not call them here.

After swiftly dealing with the medicinal herbs, Lin Cheng started to forge the pills.

The medicinal pill that he was going to refine this time was called 'Yuan Recovery Pill'. As the name implied, it was able to swiftly recover one's Yuan Power after consumption. This was because the medicinal pill originally contained a rich amount of Yuan Power.

If he was injured, or if he took a Origin Recovery Pill at a critical moment with insufficient energy, it would almost have the effect of saving his life.

Every time Lin City concocted pills, they would miss the Blue Flames of the past, and this time was no exception.

In order to refine the medicinal pellets that he needed, Lin Cheng naturally had to put in a lot of effort. He even hoped to refine a Sixth Cycle or above medicinal pellet, but unfortunately, his own strength was lacking and he did not have a strong flame. Thus, he could only refine a Third Cycle medicinal pellet.

There were very few medicinal materials in Lin City, and in less than an hour, he had already finished refining them. As he looked at the medicinal pellets that were emitting a strong fragrance, the corners of his mouth couldn't help but curve slightly.

Even though he only had five pills, that was sufficient for him.

"With these pills, I can at least guarantee that I won't lose my life if I get injured while searching for the Azure Flame."

Lin Cheng thought to himself, "It's just a pity, my current cultivation level is too low. Before reaching the Arterial Circulation Realm, even if I were to reach the location of the blue flames, I wouldn't be able to take them all away."

In his previous life, Lin City had gone through countless hardships, risked their lives several times, and only then did he finally manage to find out a wisp of blue flame. He understood more than anyone else how terrifying blue fire was.

As long as he could break through his shackles and reach the Pulse Wheel Realm, it would not be long before he would be able to obtain the Blue Flames.

What Lin Chen was most worried about right now was whether someone had discovered the green blue flame or even taken it away. If that was the case, it would be extremely difficult for him to obtain another powerful flame.

He had to speed up his training!

Lin Cheng secretly clenched his fists.

After putting away the five Returning Energy Pills into his pocket, Lin Cheng opened the door and walked out of the stone room. Only then did he realize that the sky had already darkened.

"Master Lin!"

Following the respectful shout, the shopkeeper hurried over. Behind him were the two servants from earlier in the day, "Master Lin, dinner is ready, would you like to eat now?"

Lin Cheng was startled for a moment, he did not expect that the shopkeeper would arrange everything so well, but after thinking for a bit, he still refused, "No need, I'm going back now, I'll come back tomorrow morning."
