It may be that he was a little nervous to be stared at by a few people, and after waiting for a while, the elf said in a hurry: "It's the Myelin Cleansing Pill, the master used a Myelin Cleansing Pill for me, and I am already a top qualification now." ”

The three of them used the pupil technique to look at the elf, it was indeed the trunk meridians were all connected, and the meridians on one arm were also all connected, but what kind of elixir was the myelin cleansing pill, although the brother and sister knew the effect of this pill when they heard the name, but the two of them had never seen so many cultivation pills! So the two turned their heads to look at Liu Lao.

I saw that Old Man Liu seemed to have slapped his forehead hard just now, and now he is rubbing the place that was reddened!

Seeing the two of them looking over, he hurriedly spoke: "I've heard of the Myelin Cleansing Pill, but I haven't used it, I forgot it, this thing seems to have only appeared in the auction house a few times, and the highest price was auctioned to 26 million gold coins, it is a really priceless good thing, it can wash the marrow and cut the hair, change people's innate qualifications, as long as you take one, you can at least have top-level cultivation qualifications." ”

"How many pills can each person take of this thing, and if you eat a few more, you can directly become a god?" Yang Xiaoxin asked curiously.

Hearing this, Liu Lao just squirted out a sip of wine in his mouth, and stammered: "Few... Small table... Not to mention that this pill is difficult to refine, the materials are even more difficult to find, and this pill can only be taken by one person at most, and the most that you eat is equivalent to the Exorcism Pill and the Pulling Heaven Pill, which can only be used as an elixir to drive away erysipelas, which is really a waste. ”

After a pause, he continued: "And to become a god, I have never heard of taking a few pills to become a god, otherwise I would have worked hard to cultivate something." ”

In this way, a few people will understand, but I didn't expect Professor Yu to spend so much money on elves, it seems that Professor Yu attaches great importance to the talent of elves!

Yang Xin'an suddenly asked Liu Lao: "As an alchemy master, Professor Yu should have a great reputation, Liu Lao, do you know anything about her?"

She has only known the elf for more than ten days, and Professor Yu can be so good to her, she can't help but make Yang Xin'an feel alert about it!

Fortunately, Liu Lao replied, "Yu Shulan, this girl, she has a very good personality and a good personality, especially the beauty pill she developed, which is basically in short supply every year, and she is not short of money." ”

Hearing this, both brothers and sisters had the urge to spurt blood, but their hearts were also relieved.

Seeing that the night was getting late, several people stopped discussing and went back to their rooms to rest.

Early the next morning, several people finished breakfast early, and were about to go to the city lord's mansion to talk to the master about some business.

As for the samples of rickshaws and bicycles, the brother and sister think it is very easy to get it, after all, they all know the principle of knowledge, that is, the hardware needs someone to be able to make it, which is really a bit troublesome.

When they came to the backyard of the City Lord's Mansion, Master Yan Feihua and the little junior sister were talking in the small pavilion, and when they saw the three of them coming, they hurriedly beckoned: "Why did the three of you come over today, I thought you would go out to play?"

Yang Xiaoxin hurriedly pounced, hugged one of Yan Feihua's arms and said coquettishly, "Teacher... Xiaoxin and her brother don't have the resources to cultivate now. ”

Hearing Yang Xiaoxin's words, Yan Feihua laughed, and even Bai Xi next to her wrenched her fingers and said, "Sister Xiaoxin, you are lying and deceiving people, aren't you the Yuan Stone who gambled on stones and earned hundreds of millions of gold coins? ”

Yan Feihua saw that Yang Xiaoxin was stunned and had nothing to say for a while, so she laughed and said, "Let's talk about it, do you brothers and sisters have anything to do for you now?" ”

"That's the master, you take a look at this first. ”

Saying that, Yang Xin'an handed over the prepared drawings, and then continued: "Yesterday, when the three of us took the servants to play, we found that those bustling streets were not suitable for carriage traffic, and it was very inconvenient, so I didn't sleep all night, and figured out this rickshaw, which is light and convenient, occupies a small area, and it is not a problem to pull two people at a time." ”

Looking at the drawings handed over by Yang Xin'an, Yan Feihua thought carefully before saying: "Well, the prosperity of these streets is in the flow of people, this kind of rickshaw can be manufactured, of course, it is good, but the material should be made of steel, which is a bit difficult, now the steel smelting speed is relatively slow, and it cannot be made on a large scale, the cost of steel materials is too expensive, this rickshaw is not something that can be sold at a high price, and we also have a soft car, in fact, the necessity is not so great." ”

The brother and sister felt like they had suddenly lost their strength, lying on the stone table softly, listening to what the master said, the two remembered that the steel refining in this world is still in the stage of human hammering, and it is impossible to carry out mass production, and the spring shock absorption, the bearing may not be able to be made, and this money-making plan can only be temporarily stillborn.

"It's a problem, well, can we try to make a wooden one? Alas, it doesn't seem to work, and the wooden one is the same as the board car, and the price is lower when you sit down. Yang Xin'an grabbed his hair and said disappointedly.

Yan Feihua looked at the soft appearance of the two brothers and sisters, and said with a smile: "You both have hundreds of millions of assets, even if you buy cultivation resources, it shouldn't be a problem to spend a few years! Besides, can't the academy earn some credits in exchange for resources, with the talents of the two of you, after adding resources, the cultivation realm will be high, won't you still be able to get some rare treasures in danger?"

Since this plan failed temporarily, the brother and sister had nothing to say, and chatted with the master about the doubts about cultivation, and by the way, they told her about the appearance and characteristics of the coal mine, and asked her to help ask someone to pay attention to it, and told the little sister a story about the god list, and by the way, after staying for lunch, the brother and sister took the elf home and asked Liu Lao to go to the flower street to watch the Oiran head selection competition.

The holiday ended quickly, and although the bikes could not be mass-produced, the siblings still customized a few, of course, for the sake of the future, these were customized separately, and the siblings took them home and assembled them themselves, which needed to maintain exclusivity.

The inscription is like a faint line of lines wound around each part of the bicycle, the dark metal frame and the tough solid cow rubber tires, which are only depicted with three simple inscriptions, the solidity of the earth, the hardness of the gold, and the lightness of the wind.

The siblings found it a bit difficult to make the chain, and they didn't like the triangular seats, so they had to avoid the problem by using the exaggerated shape of the front wheels.

Because it is customized, the brother and sister don't care how much money is spent, a pedal bicycle that looks very stylish is done, at least Yang Xin'an feels that most sections of the road in the entire Dawn City can be go, even outside the city, as long as it does not rain, it can be driven well.
