Half a month to advance to the fourth stage of Dou Zhi, and another half month later to advance to the fifth stage. This kind of unparalleled cultivation speed, even if it was the former Xiao Yan, Im afraid he could only look up to him in admiration.

  Although every upgrade of the Dou Qi increases the difficulty of promotion, at the current speed, it shouldnt be too difficult for Xiao Yan to cultivate to the seventh segment of the Dou Qi within a year.

  Of course, on this premise, it is necessary to have sufficient foundation-building spiritual liquid. Otherwise, before Xiao Yan cultivates the seventh segment of Dou Zhi Qi, he will be seriously injured or killed in Yao Laos training. After all, without the repairing effect of the foundation-building spiritual liquid, relying solely on Xiao Yans current fragile body, apart from dying due to excessive blood stasis, there is no other way out.

  So, what Xiao Yan needs to do now is to buy materials again and refine the Foundation Building Liquid. It sounds simple, but Xiao Yan has encountered a not-so-small problem... he doesnt have much money left.

  Sitting on the bed, Xiao Yans small face was full of bitter smiles. He didnt think that he would be forced to this extent by money. He stretched out his hand and calculated carefully... The remaining money from buying materials last time was more than 900 gold coins. Using this money to buy those high-grade materials again, it was clearly not enough.

  Propping up his chin, Xiao Yan pondered for a moment before suddenly speaking up: "Teacher, can we use younger Purple Leaf Orchid or Bone Cleansing Flower?"

  "Its possible, but the medicinal effect will be weakened. Ive configured the Foundation Establishment Spirit Liquid for you, and it was carefully refined according to the most suitable combination." The voice of Medicine Old came from the ring.

  He blinked his eyes and Xiao Yan lightly laughed: "It doesnt matter, this time just use the worst materials to refine it."

  "The worst? Then the effect will be poor, and in that case, you may need half a year to break through the next stage of Douzhiqi." The old pharmacists voice was tinged with some dissatisfaction, presumably he had already furrowed his brow.

  "Is the money not enough? Go find that little girl, with her background, giving you tens of thousands of gold coins to spend is just a small matter, if not, ask your father for it, why lower the efficacy of the medicine and delay your own cultivation..."

  Listening to Yao Laos suggestion, Xiao Yan shook his head helplessly: "Just think of it as my boring self-respect playing tricks on me. How can I go find a girl to borrow money from three times? My father is also out of the question. Ive been avoiding him for two months now. And what if he asks me questions and gets to the bottom of things, wouldnt that expose you, Teacher?"

  "Teacher, can this Foundation Building Spirit Liquid be configured by others?" Xiao Yan suddenly furrowed his brow and asked.

  "Hey, kiddo, on the continent of Dou Qi, there are countless medicinal materials. To concoct dan medicines with different effects, you must sift through these numerous materials to find those that can neutralize the violent energy within the magic crystals you need to refine. Only then can you successfully refine the dan medicine you need. If you randomly combine them, a ruined furnace and damaged dan are minor issues; whats scary is if theres a backlash... Hehe..."

  At this point, Yao Lao chuckled to himself before continuing: "This Zhu Ji Ling Ye is a medicinal formula that I spent several years experimenting with before finally perfecting it. Of course, perhaps someone else might coincidentally stumble upon the same formula, but the probability of that happening is extremely low."

  "Moreover, in the process of refining, the degree of fusion and proportion of the three materials, as well as the concentration of the flame, all require countless experiments and extremely strong spiritual perception to grasp. Otherwise, do you think why every alchemist needs to be taught by a master? Wanting to become a powerful alchemist without guidance from a famous teacher is basically impossible. Just those experimental prescriptions alone can take up your entire lifetime."

  "So, I wont say that for the entire Dou Qi continent, but as for this Ga Ma Empire, I can guarantee that no one will be able to refine a foundation-establishing spiritual liquid like mine!" As he spoke, a hint of pride seeped into Yao Laos words.

  Some were shocked at the complexity of the foundation-building spiritual liquid, Xiao Yan subconsciously licked his lips. When he first saw Lao Lao refining medicine, it seemed very simple, but now he realized that refining elixirs was far more than what could be seen on the surface.

  The world of alchemists is indeed vast and unpredictable, no wonder it has become the most noble profession on the continent of Dou Qi.

  After the shock, Xiao Yans heart was filled with joy, and he smiled lightly: "Teacher, Im not going to use the worst Zhi Ji Ling Ye for cultivation. I plan to take it to the auction house to sell it. Right now, were short on funds, but once we get the money, we can buy better materials. After all, refining Zhi Ji Ling Ye is just a trivial matter for you, what do you think?"

  "Its like that... never mind, its not uncommon for an alchemist to auction off their own elixirs. And that Foundation Establishment Spirit Liquid is just a low-grade cultivation medicine anyway, so selling it doesnt matter." The Medicine Old Man said nonchalantly after a brief moment of silence.

  Hei nodded in agreement as he listened, Xiao Yan chuckled and packed up his things before hastily rushing out of the room.

  Since this time does not require very good medicine, Xiao Yan simply randomly selected the lowest-grade purple leaf orchid and bone-washing flower in the pharmacy. As for the wooden attribute magic crystal, he also bought a cheapest green wood mouse magic crystal after several rounds of screening.

  Having bought all the necessary materials, Xiao Yan found an inn and hid inside to let Medicine Master refine the Foundation Establishment Pill.

  This times Zhū Jī Líng liquid, not only is the medicinal power much weaker than last time, but even its color has changed from a crystal clear emerald green to a mottled cyan green...

  He stored the fist-sized Foundation Building Spiritual Liquid into a small white jade bottle he had previously purchased, and only then did Xiao Yan let out a sigh of relief.

  He put away the jade bottle and left the inn, striding swiftly towards the largest auction house in Wutang City.

  The previous Xianjian book group has been disbanded. Wait a few days and the Tianya book group will be re-established. Sorry to those friends who were kicked out of the group ^_^
