When Nuo Lan returned to Tongtian Castle, it was already ten days later, although the situation did not improve during this period, but at least it did not continue to deteriorate, Liu Yin boldly delegated power to the shopkeepers, and they also stabilized the situation with their years of experience in business houses.

Nuo Lan didn't have time or want to explain more about his actions, but immediately combed through the information that had accumulated during this time, and after spending a whole day reading it, he fell into a long contemplation again.

As expected, Babel is growing too fast, and the problem of manpower shortages cannot be solved just by thinking about it.

"Feng Qi City Lu Wei, ask to see the treasurer of Nuo. ”

Since Nuo Lan hadn't been free for a moment since she came back, she hadn't had time to mention the matter of the Lu family to her, but she didn't expect that the other party would take the initiative to visit her at this time.

The Lu family had long expected the trouble of Tongtian Castle, and they also saw it in their eyes, and they only appeared at this moment late, and they also had their own considerations.

How can the Lu family say that they are also outsiders, and they were working under Jubao Zhai earlier, even if Tongtian Fort is not pursued, its identity is really sensitive, if it appears earlier, not to mention whether it can get the trust of Tongtian Fort, just take advantage of the absence of Lan Xuan's big shopkeeper Nuo Lan at this point, you can let someone with a heart lay the root cause for it in the future.

Since the current Lu family plans to hold on to the big tree of Tongtian Fort, they will naturally not put themselves in a dangerous situation, so they have deliberately waited until now.

"Lu Wei?" Nuo Lan's expression was not too good, there were too many things that gave her a headache.

Seeing this, he hurriedly took the opportunity to offer his meager strength and quickly explained the origin of the other party and what the other party's firm had done before.

Nuo Lan's eyes lit up after hearing this, and he immediately got up and greeted him: "Little girl Nuo Lan, I've seen everyone Lu." ”

Lu Wei saw Nuo Lan and Chi Lai come out of the house together, and hurriedly saluted, but also felt glad in his heart that he had made the decision to wait for Nuo Lan to return.

Late to see that the two of them chatted endlessly as soon as they met, they stopped being bored with themselves, and left quietly, and at the same time they breathed a sigh of relief in their hearts, Lan Xuan is his own industry, even if he doesn't care by nature, it is impossible not to care, now it's okay, professional things are handed over to professional people, and he ends up relaxed.

However, he still has something to do, and now that the materials provided by Liu Yin have been prepared, it is time to solve the problem of the nine soldiers.

Late to enter the alchemy room, this is the first time he has refined the Yuan Dan, but he is a little curious about what is special.

The previous steps are as usual, except for the last step:

"In alchemy, please wait, the estimated completion time, 7 days. ”

What's the situation?Zhongpin Yuan Dan takes so long?

It only took 30 minutes to refine a superb elixir before, and the grade was only two orders apart, and the time taken was hundreds of times different?

With the doubts in his heart, he belatedly walked out of the alchemy room, found Liu Yin and began to humbly ask for advice.

"Oh, come on, you're planning to start refining the Vitality Yuan Pill so soon?" Liu Yin had a hint of surprise on her face.

Chi Lai was curious: "Since the materials are ready, of course, the sooner the better, aren't a few seriously wounded still waiting." ”

Liu Yin suddenly thought of the mysterious space that Luo Hong was in when he forged, and he knew something in his heart: "It takes at least two months to refine a medium-grade Yuan Dan normally, and it will take at least two months for a seventh-order alchemy grandmaster, so it seems that Aunt Liu is still underestimating." ”

Two months...... This is whether your sister is alchemy or refining, and she has to give her a proper rhythm of life.

Liu Yin seemed to see the belated doubts, and explained again: "Normally, a seventh-order alchemy grandmaster can at least have a god-transforming stage cultivation, for this kind of power, a simple meditation and cultivation is a few years at every turn, and two months is just a blink of an eye. ”

Liu Yin was already immune to all kinds of miracles and confusion in Chi Lai, even if she told him that Chi Lai was actually an immortal, she would not be surprised, after all, the various methods shown by the other party were far beyond Liu Yin's knowledge.

Worried about making money from alchemy, Chi Lai had to consult the question he was most concerned about: "How many spirit stones can that medium-grade Yuan Dan be sold for?"

Liu Yin thought about this question for a long time, because she hadn't been exposed to something of this grade for a long time, and she confirmed it in her memory for a long time before she replied: "There is a big difference in price between different middle-grade Yuan Dan, and in the case of the Vitality Yuan Dan, it should be worth about 100 million lower-grade spirit stones." ”

"100 million!" belatedly felt that he had discovered a new way to get rich, so that with only five Vitality Yuan Pills, he could raise the Tower of Babel to level 20.

But then Liu Yin's words brought him back to reality: "It is difficult to circulate in a small place, even if someone sells it, no one can buy it, and in the Boulder City where Nuo Lan was located before, there will occasionally be treasures of this grade, but that is a special case, in fact, there will never be such a thing as a Zhongpin Yuan Dan in the entire Chu State except for Boulder City." ”

"And even if you can find a buyer, it is difficult to find the raw materials for refining Yuan Dan, this two-thousand-year-old Snow Mountain Lingzhi is said to be difficult to appear once in ten years, which is not an exaggeration at all in a sphere of influence like the Chu State, let alone the even more barren Yan State. ”

Although the words are very shocking, but at least it is a choice, it is a big deal to be cheeky and make Xuanyuan Jian work hard to run two more times, which is not enough for him to go back and forth for a few days if he is in full speed alone.

"Why is there only one grade difference between the Spirit Pill and the Yuan Pill, and there will be a world of difference in both value and refining difficulty?"

Liu Yin showed a wry smile: "Only when you come can you say that refining Yuan Dan is so easy, because from the point of view of division, Yuan Dan already really belongs to the category of immortal pills, Aunt Liu doesn't know how you refine it, but under normal circumstances, the biggest difficulty in refining Yuan Dan is that you can't use mortal fire, if you use mortal fire, no matter how good the materials are, you can only refine the elixir level." ”

"What kind of fire is that?"

"There are ten origin fires in the world, and those who can control the origin fire must at least have the cultivation of the god transformation period, otherwise they will die if they touch it. ”

Even so, I didn't receive any prompts from the system, and it seems that this difficulty is not difficult for the system.

However, since there is such a powerful flame in the world, it is necessary to let the belated generation have some bold ideas, after all, there are still so many empty towers waiting to be filled.

"Aunt Liu, do you know where there is an origin fire?"

Liu Yin had an expression that knew this: "Do you remember that Jubao Zhai had a deacon who cultivated as a golden pill, and his precious gourd contained a wisp of true fire vitality, which was taken from the Sun True Fire in the Ten Origin Fires, with the power of one-ten-thousandth of the Sun True Fire, if my inference was right, Jubao Zhai should have a fire somewhere." ”

It's Jubao Zhai again, it seems that we are really born to be impulsive, and I can't help but think maliciously for a long time.
