When he came to the underground auction house again, Zhang Mo was already familiar with it, but he still didn't use the trick in the ghost mask, but used his own mask.

The people who work in the underground auction house seem to be wearing grimace masks, and the people in charge of reception at the teahouse show their real faces without masks.

Grimace masks are also graded, and the lowest level is the white grimace mask, and these people are generally responsible for basic work such as leading the way and guiding the way.

The person who received Zhang Mo was a silver ghost-faced masked man, who said to Zhang Mo in a very strong voice: "The other party has provided the information you need, and please check it after paying the spirit stone." ”

Zhang Mo was not verbose, and directly paid enough spirit stones, and the silver grimace mask man handed Zhang Mo the jade slip with the copied information.

Zhang Mo immediately held the jade slip and immersed his divine sense, and all the relevant information about the poison arrow wood immediately appeared in his mind.

It turned out that this poisonous arrow wood grew in the range of the Hundred Barbarian tribes in the south of the Great Qin State, and these hundred barbarian tribes nominally obeyed the dispatch of the Great Qin State, but in fact, they did not listen to the Xuan, and they did not obey the control of the imperial court at all, and the reason why the Hundred Barbarian tribes could be so unscrupulous was because they were located in the southern barbarians, and the miasma was quite powerful.

At the same time, the sacrifice of the Hundred Barbarian tribes also has a variety of terrifying abilities, the most important thing is that they can summon some barbarian gods to possess and fight, which is extremely powerful, and at the same time, there must be a temple warrior around the sacrifice, this temple warrior can be possessed by the soul of the spirit beast during the battle, so as to instantly have a strong strength, there are sacrifices and temple warriors, and the Hundred Barbarian tribes are naturally fearless.

The warriors of the Hundred Barbarian tribes will smear the juice of the poison arrow wood on the arrows, and use the arrows smeared with the poison arrow wood venom against the enemy during the battle, and the middle one will immediately die, and there is no time to take the antidote.

In the previous wars between the Hundred Barbarian Tribe and the Great Qin State, the Hundred Barbarian Tribe relied on the venom of the poison arrow wood to cause heavy casualties to the soldiers of the Great Qin State, so this poison arrow wood was treated as a holy object in the Hundred Barbarian Tribe, and it was very difficult for outsiders to obtain the venom.

Although there is poisonous arrow wood venom for sale on the market, the amount that Zhang Mo needs is not ordinary, and it will definitely not work if he does not go to the Hundred Barbarian Tribe.

As soon as he thought of this, Zhang Mo frowned, the information related to this poisonous arrow wood gave him a real headache, it seems that he has to be fully prepared, Zhang Mo has always liked to plan for a rainy day and be prepared to deal with everything.

For this reason, Zhang Mo decided to refine a few pieces of mid-level rune paper, which required the purchase of some high-grade spirit animal skins.

When he came out of the underground auction house, the storage bag was bulging, and most of the 500,000 spirit stones sent by Yue Yang had already been spent, Zhang Mo had to sigh that the spirit stones came and spent quickly, of course, when his hand patted the storage bag on his waist, he was also a little relieved in his heart, this time he spent so many spirit stones, and naturally he also gained a lot of good things.

Three days later, Zhang Mo followed Yu Yu to a mountain villa on the outskirts of Wuling County.

In addition to Yu Yu and Zhang Mo, there is only a big man with a meaty face and a middle-aged man with a shrewd appearance.

"This is Faming Daoyou, who is already a second-grade alchemist. Yu Yu pointed to the big man with a meaty face.

Fa Ming glanced at Zhang Mo, his face was full of disdain, Zhang Mo naturally wouldn't use his hot face to stick to other people's cold butts, and he didn't pay attention to Fa Ming at the moment.

Yu Yu continued to introduce a little embarrassed: "This is Yu Wei Daoyou, and he is also a second-grade alchemist. ”

"Xiao Daoyou is already a non-grade alchemist at a young age, and he really has a bright future. Yu Wei squinted his eyes and smiled.

"Yu Daoyou, don't laugh, I'm just a layman who hasn't stepped into the alchemy sect yet. Yu Wei's enthusiasm did not make Zhang Mo feel good, but made Zhang Mo secretly vigilant in his heart.

He is just a no-grade alchemist, and with the identity of the other party, it would be good if he could treat him with an equal attitude, but Yu Wei's words revealed a hint of praise, which was unusual.

"Hehe, how can the person who can be favored by Xiao Yu be a layman?" Yu Wei's eyes flashed with a gleam and said, "Haha, Xiao Yu, you said yes, right?"

Yu Yu's face was even more embarrassed, and he didn't say much at the moment, and directly changed the topic: "Since the people have arrived, then let me first talk about the refining method of this Xiaodu Divine Pill." ”

As soon as it came to refining Xiaodu's Divine Pill, Yu Yu's expression immediately became serious, and Zhang Mo and the three of them also changed to a serious appearance.

"Alchemy is divided into four steps: ascending, descending, burning and condensing, each step is not sloppy, if there is a slight difference between the front and back, I am afraid that the previous efforts will be wasted. Yu Yu said with a solemn expression, "I hope that Zhang Daoyou can assist me when ascending the Dan, Faming Daoyou can make a move when descending the Dan, as for Yu Wei Daoyou, just intervene when burning the Dan, and finally when you condense the Dan, you need the three of you to work together." ”

After listening to Yu Yu's words, Zhang Mo and the three of them were silent, Zhang Mo looked around and asked: "Yu Daoyou can set up a formation around him, if Xiaodu is successful in refining the Divine Pill, I am afraid that there will be a vision, if there is no formation to cover it, it will definitely cause the covetousness of people with bad intentions." ”

"Zhang Daoyou, although rest assured, I have purchased a set of Five Elements Bagua Array before, which is enough to block the vision of Dancheng, and at the same time, it can also prevent unrelated people from entering the villa and affecting our alchemy. Yu Yu said confidently.

"Then let's start as soon as possible!" Yu Yu said impatiently.

Then Yu Yu took the three of them to a small well in the villa, and before Zhang Mo and the others could react, Yu Wei exclaimed: "Alchemy Well! It seems that Xiao Yu, you have also spent a lot of effort for this alchemy." ”

While Yu Wei spoke, a trace of greed flashed in his eyes, this alchemy well is a method that some alchemy masters like very much, which can effectively improve the yield of pills, of course, the construction method of alchemy well is secret, and there are few alchemists who can know it, and most alchemists are not interested in teaching others how to build alchemy wells.

Zhang Mo casually glanced at Yu Wei, and of course saw the greed in his eyes, but Zhang Mo was not interested in paying attention to Yu Wei, because his attention was all attracted by the alchemy well in front of him.

The size of this wellhead is just enough to accommodate an adult, the whole body of the wellhead is cast by unknown metal, Zhang Mo probe looks, the bottom of the well is still metal casting, about several zhang deep.

Around the mouth of the well is a circular jade platform, on which are carved many complex arcane runes, and it is an auxiliary magic circle.

As soon as Zhang Mo stepped on the jade platform, he felt a scorching air flow coming from under his feet, and immediately said with some surprise: "Innate earth fire, this is one of the best fires in alchemy! With this fire, Yu Daoyou's Dancheng probability can increase by a few points." ”

"Zhang Daoyou is really discerning, I bought this villa and took a fancy to this congenital earth fire, don't hide it from all fellow Daoists, this alchemy well is built on top of the innate earth fire. Yu Yu said quite smugly. "Then we can start alchemy, and ask the three Daoists to find a good position on the magic circle, and then we only need to input spiritual power to control the medicinal materials in the Danjing. ”

Zhang Mo then found a position close to Yu Yu and stood up, while Fa Ming and Yu Wei were obviously in a group, and the two stood in a row.

Then Yu Yu patted the storage bag and took out all kinds of medicinal materials, many of which even Zhang Mo had never seen, and some medicinal materials Zhang Mo recognized, but the color was good that Zhang Mo had never seen, the year was long, the timing of the medicinal materials was good, and the preservation was perfect.

As the medicinal materials kept being put into the alchemy well, Zhang Mo's heart was also secretly surprised, this Yu Yu had almost continuously invested hundreds of medicinal materials, but it seemed that he had not stopped yet.

After a full cup of tea, Yu Yu threw the last medicinal herb into the alchemy well, and Zhang Mo secretly estimated that Yu Yu used no less than five hundred kinds of medicinal herbs.

"Let's start, and ask Zhang Daoyou to help with all your might!" Yu Yu said with a sullen sigh, and at the same time took the lead in urging the magic circle infused with spiritual power under his feet.

Rumble!

There was a muffled sound at the bottom of the alchemy well, and a hot breath immediately surged up from the bottom of the well, at this time, Zhang Mo did not hesitate to pour spiritual power into the magic circle, and the light on the jade platform was great, and the magic circle began to exude a white light, and even the entire alchemy well began to glow with a layer of milky white light.

Under the effect of the magic circle, the violent power of the earth fire began to gradually soften, and then flattened.

At the same time, a strong medicinal fragrance wafted from the alchemy well, and the medicinal materials that Yu Yu threw into the alchemy well before had already begun to melt at this time.

This process is to melt all the medicinal materials into a liquid, so that the medicinal materials form a pill liquid, which is suspended in the alchemy furnace or alchemy well, so it is also called shengdan.

This is the first step, and of course it is also a crucial step, if the Dan liquid is not fused well, then the subsequent steps are easy to go wrong, resulting in the pill not being able to travel.

With Zhang Mo's experience in his previous life, he was naturally hand-to-hand, of course, on the surface, his expression was very grim, and the spiritual power under his feet was not slow, and the earth fire was controlled by the magic circle, and it was also slowly melting the medicinal herbs one by one, and after becoming liquid, the temperature immediately dropped, and then floated from the alchemy well to mid-air and merged into the colorful pill liquid.

Although this process seems simple, if the temperature is not well controlled, the liquid melted by the medicinal materials will be evaporated, and the lack of medicinal materials will naturally be wasted, which is completely controlled by the alchemist's feel and experience.

Fortunately, Zhang Mo's alchemy level is not bad, Yu Yu's own strength is also amazing, the two of them cooperated and spent a full hour to melt all the medicinal materials into Dan liquid, at this time, there was a fist-like irregular liquid floating in the alchemy well, there were quite a lot of impurities in this liquid, and various medicinal properties were not fused, and the surface was often convex and concave, looking as if it was about to explode, but Shengdan was successful, and the next step was to descend Dan.
