After taking a look at the alchemy process of the Spider Girl in the alchemy hut, Liu Zhi generally understood the difference between 0% and 30%, this is not a problem of success rate, alchemy in the alchemy hut, as long as the materials are right, you can refine things, and these 0% and 30% are the data of the yield rate.

According to the situation, after the new formula is brought in, you can directly refine the alchemy potion, but the production is all the minimum standard of the tabula rasa, if this recipe reaches 30%, then there is a 30% chance of making a good alchemy potion, and the effect may be one to two times that of the tabula rasa potion.

Further up, there will be boutiques or more changes, but now Liu Zhi can only see 30% of the situation at most, so he doesn't know much about the information behind it.

Now Liu Zhi is thinking about whether as long as one person improves the data behind the alchemy formula, other people can also get corresponding blessings in the alchemy hut, or only this person can get the corresponding reinforcement when he is here.

If it is the former, then the situation will be much more convenient, although the current alchemy hut can only be arranged with one undead servant, but it does not mean that there will be no more opportunities to arrange manpower in the future, if it is the latter, then the situation will be different, Liu Zhi may need a professional alchemist to specialize in this, then the choice of the plan will be much less.

The Spider Girl didn't have any problem with Ryuji throwing herself in the alchemy hut, and she happily listed a large number of materials to Ryuji, planning to make the spider silk needed to build the city wall in a short time.

But at this time, Ryuji ignored her, and at this time, Ryuji saw a message that popped up, and was in deep thought at this time.

[Detected sub-class Alchemist upgrade tree promotion criteria: Alchemist - Alchemy Expert - Alchemy Master - Alchemy Grandmaster.] 】

[Detected sub-class - Alchemist employment criteria: 100% mastery of alchemy recipes 10 copies (0/100), production of good alchemy potions (0/1000), production of 50 copies of high-quality alchemy potions (0/50), research of a new alchemy recipe (0/1)]

[Note: Alchemist is a professional sub-class, which plays a very important role in the promotion of various professions in the legal system, please give priority to learning.] 】

Liu Zhi glanced up at the recipe here, and put the spider silk recipe of the Spinning Spider Girl on the box, there were exactly ten kinds.

He thought for a moment and asked, "Anyway, I don't have anything to do now, why don't I collect the recipe to make these alchemy potions." ”

The Spider Girl didn't notice Ryuji's attitude, but seeing that Ryuji was willing to stay and help her, she was very happy, and even her voice became a little faster.

Ryuji flipped out the thick book that had fallen down and examined the materials on it.

Fortunately, most of the materials are all kinds of herbs, and there are no animal blood, ores or anything like that, which may be found by forcibly looking for them in the Golden City.

Ryuji thought for a moment, walked out of the alchemy hut, and called Vidnina, who had been guarding the door.

"You arranged for the skeleton soldiers to go to the Golden City to collect some herbs, this is the need for herbs."

"He... We... No... Yes..."

Liu Zhi was stunned for a moment after hearing this, and then he understood, "If you don't say it, I forgot it, I'll take a look, okay, I know what to do." ”

After saying that, Ryuji walked towards the mass grave.

At this time, many corpses were thrown into the mass grave, and the area had obviously expanded.

"It looks like we're going to be able to reach the upgrade criteria soon." Standing in front of the mass grave, Liu Zhi couldn't help but sigh.

After the mass grave was built, Liu Zhi had actually received the upgrade standard of the mass grave, in addition to the need for a reinforced construction effect of the mass grave design drawing, the mass grave wanted to upgrade, but also its own efforts.

There is a very strict upgrade standard, the area of the mass grave must be doubled, this is something that must be done, just like the establishment of a mass grave requires flesh and blood sacrifices, without it, there is no way to build it.

And Liu Zhi threw all the corpses of those enemies he killed into the mass grave during this time, for this reason.

It's just that last time they led a team to come in from the Underworld Wilderness, most of the corpses disappeared in the explosion, or his mass grave might have expanded a little more.

Standing in front of the mass grave, Ryuji opened the control bar of the mass grave.

At this time, the number of undead produced in the mass grave is no longer the original four, except for the bone creeper, wandering skeleton, walking corpse and skeleton soldiers, skeleton sailors, skeleton goldsmiths and skeleton laborers have become the main source of labor in the Hades, and gold skeletons, skeleton archers and ritual skeletons have become the main force of combat troops.

It can be said that the mass grave at this time became an important source of manpower for the Hades Palace.

Standing here, Ryuji channeled his knowledge of herbalism into the control bar of the mass grave, and a new kind of labor-type undead was designed.

This kind of Herb Gathering Skeleton, which only requires 30 experience points to craft, can be regarded as the one that consumes the least amount of experience among the labor skeletons.

However, their role is not so simple, Liu Zhi made them, not to make them look good, they need to go to the Golden City to collect all kinds of herbs for Liu Zhi.

In order to prevent these herb-picking skeletons from running into the underworld with one or two herbs, Liu Zhi also specially made rattan medicine baskets for them, so that they could put the collected herbs into the medicine baskets, fill them and bring them back.

As for things like the medicine hoe, there are no more, anyway, the skeleton is full of bones all over its body, and it is not afraid that the hand bones will be worn out, so it is better to collect it directly by hand.

After arranging ten herb-picking skeletons and some skeleton troops to protect them to Vidnina, Liu Zhi said directly: "The next thing will be handed over to you, I won't leave the Hades Palace, I want to take this time to learn alchemy, and see if I can master the deputy position of alchemist before leaving here, anyway, it will be relatively safe in the Hades Palace, just be careful outside." ”

Vidnina didn't say anything, but she knew very well that a high-level undead like her needed Liuzhi's magic power to enter and leave the Hades, which meant that after she went out, she could only return to the Hades Palace every day if she had the opportunity to come back with herbs.

However, Vidnina also knew what choice she had to make now, she nodded to Ryuji, and with the help of Ryuji, she was sent out of the underworld with these undead.
