Half a month to be promoted to the fourth stage of Dou Qi, and a month and a half later to the fifth stage, this kind of incomparable cultivation speed, even if it was Xiao Yan before, I am afraid that it can only be expected to be as good as martial arts.

Although the difficulty of promotion will increase with each upgrade of the first stage of Dou Qi, at the current rate, it should not be too difficult for Xiao Yan to cultivate to the seventh stage of Dou Qi within a year.

Of course, under this premise, there must be enough foundation building spiritual liquid, otherwise, before Xiao Yan cultivates to the seventh stage of the fighting qi, he will be seriously injured and die in Yao Lao's beating training, after all, if there is no repair effect of the foundation building spirit liquid, just with Xiao Yan's fragile body and bones now, in addition to death caused by excessive blood congestion and condensation in the body, there is no second way to take martial arts.

Therefore, the most important thing Xiao Yan needs to do right now is to buy materials again, and then refine the foundation building spirit liquid, which seems very simple, but Xiao Yan has encountered a big problem... He didn't have much money.

Sitting on the bed, Xiao Yan's little face was full of wry smiles, he didn't expect that he would be forced to look like this by money, stretched out his fingers, and calculated little by little... The money left over from the last purchase of materials, there are still more than 900 gold coins, and using these money to buy those grades of materials last time is obviously not enough to use martial arts.

Holding his chin and thinking for a moment, Xiao Yan's eyes rolled, and he suddenly asked out loud: "Teacher, can you use a lower vintage of purple leaf orchid grass or bone washing flower?"

"Yes, but then the medicinal power will be weak, and the foundation building spirit liquid I configured for you is refined according to the most suitable combination. In the ring, Yao Lao's voice came out.

Blinking his eyes, Xiao Yan chuckled, "It's okay, let's use the worst materials to refine this time." ”

"The worst? That effect is even worse, in that case, it may take you half a year to break through the next stage of Dou Qi. There was a slight dissatisfaction in Yao Lao's voice, presumably at this time he had already frowned and moved to the ground.

"Don't have enough money, go find that little girl, with her background, it's just a trivial matter to give you tens of thousands of gold coins to spend, if you can't do it, ask your father for it, why reduce the power of medicine to delay your cultivation..."

Listening to Yao Lao's suggestion, Xiao Yan shook his head helplessly: "You just think it's my boring self-esteem, how can I go to a girl to borrow money three times or twice, my father is also forgotten, I have been hiding from him for two months, and if I ask him for money, he will ask for the bottom of the matter, wouldn't it be a leak to you, teacher." ”

"Teacher, can someone else configure this foundation building spiritual liquid?" As if remembering something, Xiao Yan suddenly frowned and asked about Wu Dong Qiankun.

"Hehe, little guy, on the Douqi Continent, there are countless medicinal materials, if you want to configure pills with different effects, you must screen out the medicinal materials that can neutralize the violent energy in the magic crystal you need to refine from these countless materials, so that you can successfully refine the pill you need, if you put it together randomly, it is a trivial matter if the furnace destroys the pill, in case there is a backlash, hehe..." This foundation building spirit liquid is a prescription that I have condensed after several years of experimentation, of course, there may be other people who can come up with this prescription by mistake, but this probability is too small. ”

"Moreover, in the process of refining, the degree and weight of the fusion of the three materials, and the concentration of the flames, all of which require countless experiments and super soul perception to grasp, otherwise, why do you think every alchemist needs a teacher's hand-in-hand teaching? If you want to become a powerful alchemist, it is basically impossible without the guidance of a famous teacher, otherwise, just those experimental prescriptions can cost you a lifetime. ”

"Therefore, I don't dare to say anything about the entire Douqi Continent, but in this Gama Empire, I can pack the ticket, and no one should be able to refine the same foundation building spirit liquid as me!" Speaking of this, Yao Lao's words were faintly full of pride.

Somewhat shocked by the complexity of this foundation building spiritual liquid, Xiao Yan subconsciously licked his lips, when he first saw the refining of the medicine elixir, he seemed to notice that it was very simple, and only now did he know that refining the elixir was far more than what he saw on the surface.

The world of alchemists is really vast and unpredictable, and it is no wonder that it will become the most noble professional martial artist on the Douqi Continent.

After the shock, Xiao Yan was a little happy in his heart, pursed his lips, and chuckled: "Teacher, I don't want to use the worst foundation building spirit liquid to cultivate, I plan to take it to the auction for auction, now I don't have enough money, when the money is in hand, we will buy better materials, anyway, refining the foundation building spirit liquid, for you, it's just a gesture, how about it?"

"So... Whatever you want, it's not uncommon for the alchemist to auction off his own elixir, and the foundation building spirit liquid is only the lowest-grade cultivation medicine, so it doesn't hurt to sell it. After a slight silence, Yao Lao didn't care about the Dao martial arts.

Listening to the black old man nodding in agreement, Xiao Yan smiled, packed up his things, and rushed out of the room in a hurry.

Since he didn't need too good medicinal materials this time, Xiao Yan just randomly selected the lowest-aged purple leaf orchid grass and bone washing flower in the medicinal herb shop, and as for the wood attribute magic crystal, he also bought the cheapest green wood mouse magic crystal after several investigations.

After buying the required materials, Xiao Yan found an inn and hid in it to let Yao Lao take action to refine the foundation building spirit liquid and move the martial arts.

This time, not only is the medicinal power much worse than the last time, but even the color has changed from a crystal clear jade color to a mottled green color...

Putting this mass of foundation building spirit liquid with half of Xiao Yan's fist into the white jade vial he had bought before, Xiao Yan breathed a sigh of relief and moved his martial arts.

Putting the jade bottle close to his body, Xiao Yan left the inn and walked towards the largest auction in Utan City.
