The first two days of the Black Dragon's Underground Kingdom were very normal. Of course, the smelting workshops that have been abandoned by the gray dwarves, but are still huge, still give people a shocking feeling. It's a three-dimensional city, and you can't tell how huge this kingdom is just from the outside. The underground space is hollowed out by multiple layers, and the middle is framed by a thick steel bracket, and a large amount of metal waste is piled up, and standing on it, I almost think that I have come to the future.

From the superficial city to Xiangxia, this kingdom is thousands of meters deep, and Xiao Yan can even see that the dark red magma is still flowing slowly in some important places. This magma is supposed to be the source of energy for this subterranean kingdom, and it supported such a large industrial metropolis 10,000 years ago. It's just that now this city is lifeless, and those endless sources of magma are slowly eroding this city while witnessing the history of this kingdom.

Although the legend is not afraid of the temperature of the magma, just like the Flame King who guards the hell, it is definitely an unacceptable thing for the black dragon to let the black dragon sink into this magma with his city permanently in the future.

Xiao Yan walked past the thick steel beams, looking at the magnificent and at the same time dim scene under his feet, imagining that tens of thousands of years ago, this place was once brilliantly lit. Countless dwarves are working in various parts of this vast kingdom, crafting more tools for exploration and then digging more underground. No other creature dared to harass these gray dwarves, and the black dragon's massive body was enough to make all malice disappear in an instant.

The dwarves excavated and multiplied for tens of thousands of years, a history that was even longer than the history of human civilization, and eventually the city was completely abandoned, and the dwarves were nowhere to be found.

"How many people will be needed if the city is restarted?"

Xiao Yan suddenly asked, such a ready-made industrial base cannot be used. It's tantamount to destroying the heavens. Even if the magma would eventually destroy this underground kingdom, before that, if used well, Xiao Yan could get too much out of it.

Carpenter looked at all this, was quiet for a while, and said, "One hundred thousand dwarves can make this kingdom run again." To regain its glory, you need more dwarves. But before that, you have to think about the logistics, just the food supply of 100,000 dwarves could bankrupt the entire Rose Territory in an instant. And there are no more minerals left in the mountains around the city. Even if you get the kingdom back up and running, you'll have to bring in minerals from the outside world, refine them here, make them here, and ship them out. ”

Xiao Yan rubbed his eyebrows. Whispered, "Well, don't go on." I can figure it out. Even these are the things I can do. In order to complete the whole transaction process with the outside world, I also need to pave the road. In this way, unless I am the Grand Duke of Dawaben, I don't even want to complete the whole process. ”

"On the other hand, my lord, if you can become the Grand Duke of Dawabia. If you add the King of East Francia to this title, then this underground kingdom will have an immeasurable effect on you. ”

Carpenter looked at his little lord with burning eyes and said, "I don't know if you have such a thing as ambition. But I must say that if you want the voice of the Lord to spread more and more people to take refuge in the Lord's presence with sincerity and sincerity, you should take a long-term view of your goals. A king of the Frankish kingdom is obviously more effective at spreading the voice of the Lord than a lord of the Rose Lord. ”

Xiao Yan smiled slightly, expressing his understanding that his subjects had such lofty ambitions, but he hadn't considered that long-term yet, leaving this trial Shijie first and putting himself in a less dangerous situation was Xiao Yan's real goal.

"If it's just for a Rose Collar, the armor we dwarves have made is sufficient. But if we look at Württemberg as a whole, we need a formalized workshop. If we want to take a long-term view, say, to supply a squadron of female paladins with a full set of armor, then we need at least a few workshops and at least 150 dwarves. As the ranks of female paladins expand, if the Knights of Punishment had their own station in the Rose Territory, our workload would simply not be sufficient with manpower. ”

Carpenter looked at the huge space under his feet, and said with some regret: "Supply the two brigades of paladin armor and daily weapon consumption, and supply the daily consumption of the entire Württemberg region, at that time, we will really want to have such a huge underground factory." ”

Xiao Yan nodded again, there was no doubt about that, and before he was sure when he would reach level 5, it was imperative to ensure a stable Rose Leader. To achieve such a goal, the first thing is to have enough military power to deter the surrounding area and ensure that no nobleman dares to take action against the Rose Leader.

Level 5 strength can make the will completely leave this trial shijie, but Xiao Yan wants more than that, and the previous attack of Kelsuga Deyi has shown that he can't leave this trial shijie so easily. At that time, even if there is no Kelthuga German will stop it, there is no guarantee that there will be no other accidents.

In other words, Xiao Yan must play his part and let little Fryman continue to stir up the entire European landscape until he achieves intentions such as the Shijie Tree and the "Lord". On the other hand, what Xiao Yan hoped to be able to take away from this trial Shijie was not only his will, but also the strength of the 5th Ring Mage/Level 5 Priest, as well as the permanent magic circle pool.

Just like Xiao Yan once said to the black dragon, he won't get it without paying, and Xiao Yan also has a hunch about whether he can bring out those things in the future, if he doesn't put in enough effort, or if he doesn't reach the level that Shijie Tree hopes, then what Xiao Yan can really get will be greatly reduced.

This is a trial shijie that has no trialists to participate in for the time being, this shijie has not issued any tasks to trialists for the time being, and Xiao Yan is now facing an invisible shijie-level task, he doesn't know where the end of the task is, but the better the task is done, the greater the benefit He is still sure of.

Due to the continuous transpiration of the magma temperature underground, although the area of this underground kingdom is huge, the overall temperature is still much better than that of the outside world. At this temperature, even in a dark space, Xiao Yan could still see some signs of life. It's just that near these strange plants or mushrooms that grow inexplicably, there are often piles of dry bones.

The Black Dragon wasn't in the vicinity of this team, and perhaps he needed enough time to make more precise preparations, since no one had actually done the work of lifting the seal before that, so there would be more things to consider. Of course, it is not ruled out that the black dragon will use this opportunity to leave this underground kingdom and go to the shijie above to find out if the fragment of the shijie tree that Xiao Yan said is really true.

This team traveled underground for 5 days, relying on the dwarves' innate sense of direction, Xiao Yan and they never got lost. But now it is impossible to guess where they have been, and where the shijie above their heads is.

On this day, as they were resting at the intersection of a massive steel support, a huge gust of wind suddenly swept over their heads, and then the black dragon slowly descended in a different shape. Looking at the bonfires scattered around, the black dragon was slightly anxious, and whispered, "Your movements need to be accelerated, and there is not much time left for you." ”

Xiao Yan replied: "What?" What happened to the shijie above? ”

"The human shijie hasn't changed much, but, as we said before, 4 dragons have quietly gathered in the Black Forest, not including me. In addition, 3 Legends from the Frost Giant's side have also arrived nearby, and it seems that the situation in the entire Black Forest is on the verge of breaking out. If you do not return to the human Shijie as soon as possible, you could be drawn into this dispute at any time. Battlefields between legends tend to be confined to certain venues to avoid causing greater impact and damage. ”

Xiao Yan frowned and said, "So, your kingdom is likely to become an important place for this great battle. ”

"It's not important, it's the only one."

The black dragon seemed to sense something, and suddenly jumped back into the air, where his body slowly unraveled, and a huge body that had once been seen by Xiao Yan and them took shape in an instant. The black dragon rumbled, "The two red dragons have entered the tunnel, and they are approaching here. Get out of here, I'll go back to you later. ”

As soon as the words fell, the air in the upper layer of the entire kingdom suddenly changed violently, and layers of waves formed in an instant, even if there was no light, the clouds composed of these air could still be clearly sensed by the dwarves.

"Let's go!"

Carpenter had already begun ordering the dwarves to prepare for the arrival of the black dragon, and when the signs of great change suddenly appeared, the dwarven leader had already begun to shout, "Go!" Come on! Go to the workshop ahead! ”

Without arguing or hesitating, the dwarves immediately ran along the unobstructed, completely suspended steel rails on both sides towards the huge steel workshop in front of them, which was half-suspended in the air. Behind them, Carpenter was dissuading Xiao Yan, and their lord was constantly bursting with a new aura at this time. These auras constantly control the wind in the vicinity, so that the dwarves on the rails are not affected by the sudden crosswinds.

"You can't stop here for too long! My lord, we must leave as soon as possible, or we may never be able to leave! ”

Carpenter yelled at Xiao Burn in an environment that had turned into a hurricane. (To be continued......)
