Returning to the crowded Kaiyang West Gate, the embarrassed Xu Yinjie's face was full of embarrassment.

Although it had only been four or five days since he left the city, it was tantamount to a few months for him, an alchemist who was accustomed to enjoying peace and quiet. Even, if he hadn't been lucky enough to meet Lu Chengfeng, he might have died at the hands of the Minotaur by now.

Because of this, he strongly invited Lu Chengfeng to sit with him in the Alchemy Union, firstly, he wanted to entertain him personally, and secondly, in order to repay him, he paid the employment remuneration promised to Lu Chengfeng in advance.

Although he has the same shortcomings as other alchemists, Xu Yinjie is undoubtedly a trustworthy person.

"Okay. ”

Faced with Xu Yinjie's kind invitation, Lu Chengfeng thought about it and agreed. The reason why he took the risk to save Xu Yinjie was to get in touch with an intermediate alchemist. Moreover, it is not easy to extract the bone meal of the fluorescent cat demon. But in the laboratory of an intermediate alchemist, there was undoubtedly all the equipment and potions he needed.

Such convenience does not have to be in vain.

Under the guidance of Xu Yinjie, the two entered a street of the Alchemy Union. As an intermediate alchemist with his own unique hair yin, he is naturally qualified to have an independent residence here. However, after entertaining Lu Chengfeng in, the first thing he did was not to take a shower and change clothes, but to go straight to the mercenary union, obviously preparing to find trouble with the mercenary team that left him.

This is a man of temperament.

After getting along for so many days, Lu Chengfeng has already seen it. Xu Yinjie is such a person with a yin personality, if he is good to him, Xu Yinjie will also treat each other more kindly. But if he offends him, Xu Yinjie will repay him. It's a bit straightforward, but Lu Chengfeng likes to deal with such people very much, because he won't get tired.

After taking a leisurely shower and changing clothes, Lu Chengfeng reworked the wounds on his body, and then had the leisure to rest, and looked at Xu Yinjie's room by the way.

Like other alchemists, Xu Yinjie's room was a mess. Throwing materials and alchemy books can be seen everywhere on the desk and floor, and there are many white notes pasted on the surrounding walls, on which some things are written down in scribbled mainland language and alchemy symbols that Lu Chengfeng can't understand, which is probably Xu Yinjie's inspiration and sudden idea. Probably because it hadn't been ventilated and cleaned for a long time, there was a musty smell in the house, and there was a lingering pungent smell of alchemy elixir.

"Looks like he's still a raunchy bachelor......"

If it were those alchemists who enjoyed life, with special assistants, servants and mistresses, they would certainly not make a mess of themselves. But then again, only such a guy who is dedicated to alchemy can develop a new potion on his own, and the effect is not bad.

Moreover, Xu Yinjie should be about to be promoted to a senior alchemist, right?

From what he said casually before, Lu Chengfeng could deduce this. A high-level alchemist, his status is completely different from what he is now!

Xu Yinjie didn't let Lu Chengfeng wait too long, and after more than half an hour, he rushed in from the outside.

Judging from the smugness and refreshment on his face, Lu Chengfeng knew the result. The team of mercenaries who did not pay attention to the morality of mercenaries and abandoned him alone in the dense forest probably suffered. Being fined and having your credit rating downgraded is only the minimum punishment, and if you don't do it, you will be forced to dissolve.

After praying for those mercenaries very insincerely, Lu Chengfeng had dinner under the hospitality of Xu Yinjie, who had been washed. Subsequently, Lu Chengfeng, who was a little impatient, entered his personal alchemy laboratory with Xu Yinjie's permission.

"Even if you use it, everything in it is free for you. Xu Yinjie patted his chest very boldly, but there was also a bit of curiosity and suspicion in his eyes: "Don't you really need my help? If you don't know about alchemy, many things in the house are very dangerous." ”

"Don't worry, it's just extraction, no problem. ”

Lu Chengfeng was very confident, before he was reborn, he had a palace alchemy master by his side all the year round. Although he had not deliberately studied alchemy, he was unable to bother him at all by extracting something from ready-made materials under the influence of his ears and eyes.

After breaking Xu Yinjie, Lu Chengfeng began to concentrate on his work.

When it comes to the weapons he will use next, Lu Chengfeng naturally strives for perfection and strives to do his best in every detail. He first cleaned and processed the bones of those fluorescent cat demons, and then softened them into a highly concentrated magic solution. After changing it three times in a row, the originally hard bones have turned into noodles. Seeing that there were no more impurities in the magic solution that had been replaced, Lu Chengfeng carried out the final treatment.

That is to use the astral grass extract as the main ingredient to extract the bones of the fluorescent cat demon.

Starlight grass is a plant that grows in shady environments and is incredibly sensitive to light. After special treatment, the leaching solution can absorb the bone meal of the fluorescent cat demon to the greatest extent. After saturation, Lu Chengfeng only needs to go through the steps of evaporation and purification, and he can get the materials he wants to gather light energy!

As mentioned before, these steps are not difficult in themselves, but they are quite boring.

If you want to get high-purity cat demon bone powder, you need the operator to have enough patience and purify it repeatedly little by little. The purer the material, the more subtle the improvement effect on the quality of the lightsaber after casting.

Therefore, for an ordinary alchemist, it might only take three or four hours to complete the work, but it took Lu Chengfeng nearly two days to complete all the work completely. In the end, those killed cat demon bones turned into fluorescent cat demon bone powder that weighed at most ten grams in a crystal bottle in his hand!

These bone powders, which radiate a soft and glowing glow, are delicate and white, comparable to the most precious pearl powder in Faroe Bay. Even if you just look at it with the naked eye, you can feel the unimaginable purity, and even Xu Yinjie is amazed. In terms of the effect of forging lightsabers, this bone meal is a hundred times more powerful than the powder effect of the Faroe Bay pearls. Just ten grams of bone meal was enough to forge a top-level lightsaber that a third-order swordsman could control, and there was still a leftover.

"Your patience is good. ”

Seeing that Lu Chengfeng stayed in the laboratory for two days and didn't come out, barely eating or drinking in the middle, Xu Yinjie couldn't help but admire it very much. Even if he goes crazy himself, that's about it. At this moment, he was a little gloomy about why Lu Chengfeng was so strong. If anyone else can show such strength in sword skills, I guess they can also achieve something.

"It's done. ”

Lu Chengfeng watched it for a long time and confirmed that the quality of these bone powders was close to perfect, so he put them away and thanked Xu Yinjie. In the past two days, not to mention anything else, just the various medicines in Lu Chengfeng's laboratory, Lu Chengfeng has used up no less than two thousand gold!

"Nothing ......"

Xu Yinjie waved his hand indifferently, as if he was about to say something, but he was a little hesitant. Under Lu Chengfeng's gaze, he finally asked, "What exactly do you want to do with it? Fluorescent Elixir? With such a high purity, there is no need at all." ”

Lu Chengfeng smiled and said mysteriously: "A weapon." ”

"Weapons?" Xu Yinjie was a little confused, what type of weapon needs the bone powder of the fluorescent cat demon?

This kind of problem involves the secret of the formula for lightser forging, and Lu Chengfeng has no intention of spreading it for the time being. He just thanked Xu Yinjie again, and after having a meal here, he got up and said goodbye. Xu Yinjie knew that Lu Chengfeng had something to do, but he didn't keep it, but just told him that he had something to do, just come to him. Moreover, as an extra thank-you, he flipped his hand and stuffed Lu Chengfeng with two bottles of ogre.

"Take it, just in case. ”

"Your friend, I've made it!" Lu Chengfeng looked at the two bottles of Yin Xian is newly made potion, and couldn't help but be a little moved, he shook hands with Xu Yinjie vigorously: "Similarly, if you need help, just ask." For some time to come, I will stop at Kaiyang, please remember my promise!"

Xu Yinjie touched his gray hair and smiled: "I also like friends with good tempers, welcome to come often." ”

.........

After leaving the street of the Alchemy Union, Lu Chengfeng began to search for energy storage gems without stopping.

Before entering the Endless Forest, Lu Chengfeng had already released tasks in both directions at the auction house and the mercenary union. After a few days, there has been a reply. Since the purchase price was fair, three squads of the mercenary union alone gave an answer. It's just that, after contacting one by one, Lu Chengfeng found that the gems/crystal nuclei they provided were not good enough, either they were unstable, or the energy stored was too small, or the energy inside was not easy to excite. In short, the deal still didn't work out.

At this moment, good news came from the auction house.

In the last week of July, there will be a large-scale auction held by three auction houses in Kaiyang City. When the time comes, all kinds of swordsmanship, potions, magic equipment, and even beautiful slave girls of different races, everything will be available. Among them, in the list of magic gems, Lu Chengfeng saw what he wanted.

【Pure Wind Crystal】

This fourth-order magic gem is produced in the Tempest Canyon. Due to its unique geographical environment, naturally bred phoenixite stores extremely pure wind energy. It is used as the core of the lightsaber, which can make the cast lightsaber attach the wind elemental attribute. The lightsaber itself is light and fast, and if it is strengthened by the wind element, it is definitely like a tiger.

Almost at first sight, Lu Chengfeng fell in love with this gem.

However, Lu Chengfeng is obviously not the only one who knows the goods. Such a superb gem is extremely attractive to martial artists below the fifth order. The price of it itself is at least 15,000 gold coins. If it is brought to the auction house, it is very possible to get 20,000 or even 25,000 gold coins.

This made Lu Chengfeng a little worried about his wallet.

He still has 30,000 gold coins on hand, and if nothing else, it should be no problem to take a picture of the wind crystal. However, when he took this gem and then entrusted the grandmaster to forge it, the money on his body was estimated to be empty. In order not to let himself fall into a miserable situation of being penniless after getting the lightsaber, Lu Chengfeng decided to try to earn some pocket money before the auction started.

This is also the daily routine that every martial artist must go through before growing into a master.
