"Master Brown, please forgive me. I have been busy learning what my master taught me recently, so I haven't come to the association to see you. I will definitely come to see you when I have learned something!" Although Brown had taken good care of him in the past, he only felt sorry for him. It would be redundant to say that he had done him a great favor.

While they were chatting, Lin Xingchen knew that a guest had arrived, so he didn't hesitate to let the guest wait and just waited at the door.

"Master Brown, what brings you to my little nest? If you need anything, just arrange for someone to come and say hello and I'll go over directly. Please come in!" After welcoming the two guests in, Xia quickly brought over tea.

"How about you two try my tea? If you are not used to it, I will change it for you."

"After Master Brown drank it, he frowned and pondered for a while, then took two more sips and still felt like he wanted more.

But the one he brought took another sip and put down the teacup!"

After seeing Lin Xingchen's eyes, Xia immediately went to change other things for the few people, and before they could speak, he hurriedly brought out a few cups of peanut milk.

"Please don't mind if the little girl doesn't know etiquette." Lin Xingchen said with a smile as he looked at Xia's rude appearance.

"It's a good thing that the little girl is lively and cute. Unlike us, we are bound by rules every day. Master Xingchen, I came to you today because I have something to ask you." Master Brown spoke directly after looking at the person opposite him.

"Master, if you have something to say, just say it. If I can help you, I won't be polite!"

"Master Xingchen, let me introduce him to you first! This gentleman is called Gauss, and he is a close follower of our Lord Kalonya. The main reason why he came back to see you this time is because of him.

"Gauss meets Master Xingchen!" Gauss, who finally got the chance to speak, couldn't wait to explain his purpose.

"This time I came to disturb the master's meditation because something was bothering our lord. It just so happened that I found Master Brown and Master Brown recommended you!"

"Here's the thing. I have a recipe here. This recipe has never been restored due to some incompleteness, but it is very important to my master, so I can only come here to trouble you!"

"Incomplete formula? That's quite interesting! I wonder if there's a copy I can take a look at!"

"Of course I have a copy here, please take a look, Master!" Gauss respectfully handed over the things he had prepared long ago.

"This is a one-to-one restoration we made based on the original. There will be no mistakes in every stroke!"

"Really? It's so rigorous, it must be a good thing!" After a snap of his fingers, a ball of light formed by illumination magic appeared in front of him.

Lin Xingchen was stunned when he saw the copy for the first time, because the words on it were so familiar.

The content of the text was indeed a recipe. The way this recipe was recorded was very strange. All the herbs needed for the medicine were listed from top to bottom, and each process and some required details were also recorded in the same way.

It’s a pity that all the records of herbs have been preserved, but the records on how to mix them are very incomplete.

If Lin Xingchen had not recognized or seen this potion, he would have definitely cursed, because a potion formula is a new world for a pharmacist, and exploring this world is the happiest thing for all pharmacists, so the preservation of the formula is very strict. According to the habits of pharmacists in the main world, all books recording potion formulas must be made of special paper that is fireproof, moth-proof, and waterproof.

Putting the paper on the coffee table beside him, Lin Xingchen ignored the young man's anxious expression and looked at Brown.

"Master Brown, can I ask you a question? How many people in the demon world can recognize this high elven language now?"

"Um... To be honest with Master Xingchen, I really don't know what this kind of writing is called! This is also the first time I've seen this kind of writing!" Brown said very embarrassedly.

"Hahaha... Master Brown, you said you've never seen it before, so do you think I would recognize it?"

"Master Xingchen, I'll be honest with you! We in the Demon World basically don't see much of this kind of writing. The only documents we have are those we seized when we fought with people from the main world.

Except for Lord Michael and the founder of the Flash Gold Auction who was active more than 200 years ago, basically no one in our demon world can understand these words. "Gauss felt hopeful when Lin Xingchen called out the words on the paper.

"Few people in the main world can understand this kind of writing. People in the main world call it high elven writing. In fact, it can also be called Chinese characters or square characters."

"These are secondary. The main thing is that there is indeed a potion recorded here. This potion is called the Life-Extending Potion! It is a very heaven-defying potion!"

"Yes, yes, yes... According to the records, this potion is called the life-extending potion. I didn't expect that you, Master, can actually understand these words. It's great! I wonder if you, Master, can prepare this kind of potion?" Gauss looked at Lin Xingchen with eagerness.

"I'm sorry, I haven't tried it so I can't say for sure, but I personally don't think it will work!" Lin Xingchen shook his head and didn't brag that he could do it.

The life-extending potion is a truly high-level master-level potion. Although Lin Xingchen has never tried it, he has seen Master Howard and others prepare it.

For the elves who don't need to worry about their lifespan, they don't care that much about life-extending potions, but humans have always been the biggest consumers of such potions because of lifespan issues.

However, this medicine has a strong drug resistance. The first dose may extend the life by ten years. In the second year, if the body is in good health, the effect can only be half as good. But it is questionable whether it can extend the life by half a year for the third time.

"Master Xingchen, I wonder if you are willing to give it a try. We are willing to provide you with the herbs for free. We only ask that if you succeed, please give them to my master first!" Gauss quickly quoted his price.

"That Gauss... you also said that this potion is incomplete, especially in some key places such as the details of the potion preparation and the temperature. To be honest, it would be wishful thinking if it takes hundreds of years to restore the potion!" Brown was afraid that the higher Gauss's expectations were, the greater the disappointment would be, so he quickly poured a basin of cold water on him.

After hearing Brown's words, Gauss, who was originally in high spirits, quickly deflated like a balloon with a hole in it.

"I am really sorry to disturb your rest. By the way, here is an invitation letter. If you are free, you can come and have a look." Gauss is indeed a character. After such ups and downs, he did not get angry but took advantage of the situation to hand over the second thing he had prepared.

Seeing that it said Pharmacist Competition on the invitation and the time was one year later, Lin Xingchen smiled and nodded and accepted the invitation.

The arrival of Gauss and others was like the rainy scene in front of Lin Xingchen. Although it brought some different things, everything returned to normal after the rain stopped.

After Gauss and his friends came, Lin Xingchen took the four children out traveling the next day. There were no valuable things in the shops and houses, so they asked an old dwarf to help look after the house and then set out on their travels again.

Because there are still many things that I haven't finished and I haven't finished reading all the books in the association, so this trip will only be to some places that are not far away.

Xia and others who were also standing at the entrance of the cave only saw boredom, but Lin Xingchen saw something different.

The water law was progressing slowly, but the Yin-Yang Secret that Lin Xingchen had been practicing since childhood had a breakthrough today.

This deceptive martial art was practiced at a pace just like a snail. After reaching the third level with this slow and steady method, there was no further progress.

Today, looking at the pouring rain, I don’t know if it was because the scene brought back memories or because it was a natural progression, but I actually broke through the third level that I hadn’t broken through in many years!

The energy and blood in his body surged like ocean waves, constantly washing over his body. With each wave's impact, his body and meridians became wider.

Jia was more careful and noticed what was wrong with Lin Xingchen. She quickly pulled Xia and Ellie away from making trouble.

This feeling of breakthrough lasted for several hours and finally dissipated. Lin Xingchen clenched his fists and felt the power in his body.

I sighed in my heart again: "I am one step further away from being a cool and noble wizard. Why can't my magic power level be improved by the breakthrough? I have to improve my physical fitness."

With his right hand stretched out, in the frightened eyes of the little guy, countless falling raindrops actually moved in sync with Lin Xingchen's waving movement.

The power of the law released by the right hand was pulled and condensed into a huge water ball. The huge water ball exploded suddenly when the right hand was squeezed, and a water-blue halo spread from the body.

The originally exploding water droplets and raindrops in the sky actually flew upwards strangely. He tried again to condense the rain into the shape he wanted, and a water man as tall as him appeared in front of him.

With a wave of his hand, the water people turned into butterflies that flapped their wings and flew high. Lin Xingchen tried for a long time before he finally dissipated this power.

The little girl knew that Lin Xingchen was very happy when she saw his smiling face. She, who had always been favored, quickly asked Lin Xingchen how he did it just now.

"This is a kind of comprehension of the law. Although I haven't encountered any extraordinary strong men from the demon world yet, I think it should be almost the same situation!"
