Compared to the city walls that have been built with great effort, the interior of the Hades Palace has not changed much in the past few months, and a large number of flesh and blood corpses are needed in the mass grave to expand the location, otherwise the matter of upgrading to level 2 will be far away.

And the same is true of the Alchemy Hut, Liu Zhi has only upgraded the Alchemy Huts to level 2 in the past few months, and the biggest obstacle here is not the lack of construction materials, but because Liu Zhi does not have enough recipes and manpower on his hands.

According to the upgrade requirements of the Alchemy Hut, upgrading from level 1 to level 2 requires the alchemy hut to store 10 alchemy recipes in it, which was completed in advance due to the spider silk formula of the Spinning Spider Girl.

But upgrading from level 2 to level 3 is not so simple, requiring that there must be an alchemist sitting in the alchemy hut, and the number of recipes required has also changed from the original level 10 to 30, of which at least 15 are required for the completion rate of 100%.

It is precisely this that has blocked the possibility of upgrading the Alchemy Hut, so that the Alchemy Huts have been stuck at level 2.

However, the Becca Stabbing Pavilion, which is used to train the Night Thorn Sword Technique, has been upgraded very quickly, and the Becca Stabbing Pavilion, which can only be upgraded to level 4 in total, has now been upgraded to level 3.

This relatively large dojo-type sword pavilion is actually a wooden house and ten tracks for sword practice, and there is no place to rest and change clothes.

However, it can be used by 20 undead or other creatures to learn the Night Stabbing Technique at the same time, and it only takes them five days to initially learn the most basic Night Stabbing Technique, no longer like Ryuji did in the mass grave before, and he has to put experience points into it to forcibly let the skeleton or walking corpse learn a certain skill.

Of course, if you stay here to study, after about 60 days, the creatures or undead who are studying here will be able to learn the Z-shaped secret sword, and as for the eternal night sword curtain taught by the level 3 Becca Sword Pavilion, it depends on the talent of the trainer rather than the time.

This is also the fundamental reason for the upgrade of Liuji, the level 1 Becca Stabbing Sword Gym is upgraded to 2 levels, and it is necessary to train 60 subordinates who have mastered the night stabbing sword.

The same is required when upgrading from level 2 to level 3, but the number of people is smaller, and only 15 subordinates who have mastered the Z-word sword need to be trained.

Now it's embarrassing to upgrade from level 3 to level 4, because the number of people needed is only 5, but the question is where Liu Zhi knows, which subordinate can learn the Eternal Night Sword Curtain.

If she had to do it, maybe only Vidnina could guarantee it, but even if she had four arms, could she count four people?

Therefore, this Becca Thorn Sword Pavilion can only be stuck in the last step without embarrassment or embarrassment, and there is no way to forcibly improve, but instead he has to ask Liu Zhi to provide at least three tracks, so that the skeleton soldiers who think it is possible to master the eternal night sword curtain have been training there.

Walking inside the Hades Palace, Ryuji didn't look back, he knew that Vidnina would always stand one step behind him on his left, so that in case of danger, she could quickly block in front of him, and at the same time, it would not affect his sword.

The Spider Girl, on the other hand, has six 'long legs' and always goes back and forth behind Ryuji, and only when Ryuji needs it, she will stop and stand on Ryuji's right side, and even then she will not listen quietly, but will keep shaking her body there, as if letting her stop will kill her.

"There is still one day, we have to do the final cleaning of the Hades, send the troops to explore in the gray fog, whether they find anything or not, let them come back, and let them enter and exit through the south gate, and when there are enough materials in the future, I will build all the other walls, and the gate will only be built in the position due south."

The Spider Girl nodded affirmatively, "Okay, I'll inform them, they should be back by now, some of them have gone too far and won't be able to catch up if they don't come back." ”

As she spoke, the Spider Girl pulled out a large amount of spider silk from her hair, and identified them in detail one by one, "This one was sent out to the team ten days ago, I remember that the team seems to have gone to the southeast, to check if there are any mineral veins that can be used, and now I have to call it back quickly, this one is ......"

After glancing at the Spinning Spider Girl, Ryuji stopped paying attention to the matter, and at this time he had already walked to the location where he had found the bones of the giant snake before.

At this time, a large amount of giant snake blood water poured down, and the white bones of this giant snake had turned blood red, and every time Liu Zhi came here, he could always feel a strong sense of oppression coming from the bones of this giant snake.

However, Ryuji has tried to treat the giant snake skeleton with spiritualism several times, but each time it has no effect, and I don't know if it was because he handled it in the wrong way, or if it was something worse.

I'm leaving this game this time, and for most of the things in the Hades Palace, Liu Zhi still has some bottom in his heart, but just the bones of the giant snake and the half of the lake to the east, Liu Zhi is not sure if he will leave with him.

And Liu Zhi has a feeling that these two things are extremely beneficial to his evaluation, so he has been circling around here for the past few days, wanting to determine the situation in these two places, or wanting to take the last chance to try again.

Standing in front of the serpent's bones, Ryuji stretched out his left hand, and the Staff of Death fell into his hand, and he held it to his right hand and chanted the spell of spiritualism aloud.

The spiritualism carried the magic of Yanagi, and little by little it was injected into the bones of the giant snake in front of him.

But this time it was the same, the giant snake skeleton did not react, and after meditating for a while to recover the consumed mana, Ryuji headed towards the east with some helplessness.

At this time, the water-scarce lake, because Liu Zhi mastered the rain control ability of the feathered serpent, was no longer short of water, and standing on the edge of the lake, he could see that under the twisted aquatic plants in the lake, a large number of gold utensils and white bones were faintly scattered.

As he did at the Serpent's Skeleton, Ryuji stood on the edge of a water-starved lake, holding the Staff of Death, using spiritualism against the lake again and again.

Since this spiritualism was performed on the entire lake, when Ryuji's magic power was injected into the lake, the white bones under the water did not even react at all.

Ryuji had long been accustomed to the changes here, and after infusing all his magic power into it, he stood by the lake and observed for a long time, and finally shook his head helplessly, the reaction here was not as good as when he was about to take away one of the gold vessels inside.

Sighing, Ryuji sat down to meditate, tomorrow is the time to leave, and then he will come back and try again one last time, okay, if it doesn't work, it can only be like this.
