Mr. You Guang looked at the forging furnace being smelted and said, "This stalactite seems to be a treasure that integrates prospecting, mining, smelting, processing, and caves. It's better for us not to take away this forge for the time being, and after figuring out the use of stalactites, mining can be much more convenient. ”

Xiang Demon Sword said: "Now it seems that this stalactite should be a mobile laboratory of Mr. Xiangxiang, it is very functional, and it can even open up a huge mine in an instant, it is likely that the mining caves below Wugongbao and Shijiazhai were opened up in this way, I just don't understand, why would Mr. Xiangxiang abandon such an artifact in the mine cave of Shijiazhai?"

Feng Luqi frowned and said: "Yes, there are four mines in the back, if there is no artifact, how would he have opened up those four mines?"

Mr. You Guang said: "I think that this stalactite should have been refined in the mine under Shijiazhai, the original intention was to facilitate the mining of the mine, but when the second component of the artifact was refined, he felt that this stalactite could be used to protect the artifact component, so he left it in the Shijiazhai mine, and the cave under it is likely to be made of this stalactite." Since he can refine one such stalactite, he can refine a second such stalactite, and maybe the remaining four mines will be opened up with newly refined stalactites. ”

Mr. Cicada said: "This stalactite is simply a mining artifact! I suspect that it is the third artifact component! This kind of artifact cannot be repeated by knowing the refining method, but also depends on chance." Even if you can refine the second piece, it will probably take more time and effort than the first one!"

"Yes, refining powerful magic weapons is often like this, the production of artifacts has special chances, without such opportunities, although one can be copied, it is impossible to reach the level of an artifact. Sima Chengzhen seconded.

"That's right, that's right, what Brother Sima said is that Western artifacts are the same, they are extremely powerful and unique magical items, all of which have their own unique history and origin, this should be the chance you are talking about, right?"

"This stalactite is indeed extremely powerful in mining operations, but it may not have any unique chance to be generated, it is not necessarily an artifact, in short, try to learn to control it first. Let's go to the Dan Room on the top floor to find clues. "Mr. You Guang sacrificed the Divine Fish Law Seal, turned into ball lightning, and brought everyone to the top floor.

There was nothing abnormal in the Dan room, Xu Yibing said: "These three Dan furnaces must be rare alchemy artifacts, I don't know if you can bring them up?"

Mr. You Guang shook his head and said, "Before you figure out how to use this stalactite, it's better not to bring out anything casually, these Dan furnaces may have some special uses here." ”

Honggu frowned and said: "But we can't always study this stalactite here, if we want to give it to the four gods to explore, without the magic seal in your hand, they won't be able to enter." ”

Sima Chengzhen's eyes lit up and said: "The princess's words reminded me that this stalactite must have some mysterious connection with the Fa Yin, maybe the Fa Yin can teach us how to use it." ”

Sima Xiaoyou is reasonable. Mr. You Guang thought that the Fa Yin could teach him how to control the stalactite, and suddenly a spiritual light shot out from the Yin Niu, which hit his eyebrows directly, he stiffened for a moment, and finally smiled: "I know how to control this stalactite! ”

The others were also very happy, Xu Yibing said: "Then do these three Dan furnaces have anything to do with controlling stalactites?

Mr. You Guang said: "You can move out, but I don't think it's necessary, this place is fully equipped, and you can come here if you need alchemy." I can control it to open a small cavern under the mine town and put stalactites in it for easy access in the future. ”

Honggu said: "Can you first make a passage, let the mushroom spirits above move down, and start building here?"

Mr. You Guang thought for a moment and said, "No problem, I can make a spiral tunnel from the side of the cave and lead to the pine forest above, and the entrance is in the middle of the pine forest." ”

Mr. Cicada said: "Then open the bottom of this cave with the bottom of the spirit pond and attract a spring to irrigate phosphorescent mushrooms." ”

Xu Yibing said: "This is not necessary, and there is a very important magic circle at the bottom of the spirit pool, which is the lifeblood of this nine-mile land, we must protect it." However, that magic circle has the ability to create water, I have done my best, I can use the Qingming Crystal Array Eye to set up a water-making array in the cave, so that it is convenient to use the opening and closing of the array eye to control the amount of water, if it is to divert water from the spiritual pool, I have to build a gate to control the amount of water, which is inevitably troublesome. ”

"Well, it's still Yibing Fairy who thinks thoughtfully, just do what you want. Mr. Cicada said to Mr. You Guang: "Then let's get to work quickly, let's take a rest after we are done, and then go find the third artifact component." ”

Mr. You Guang nodded, and according to the method given to him by the Fa Yin, a round light appeared in front of him, and he could see the scene outside the stalactite.

He then controlled the stalactites to break away from the top of the cave, turned into a circle, and flew to the root of the rock wall on the north side of the cave.

With the advancement of the stalactites, a three-zhang diameter tunnel gradually formed behind it, Mr. You Guang controlled the stalactites, and in less than a quarter of an hour, he was one zhang away from the outside of the cave, and drilled a spiral-shaped tunnel around the cave.

Since there was still a mile thick rock formation above the cave, Mr. You Guang stopped the excavation at a height close to the top of the cave and asked everyone: "There is still a rock layer a mile thick above the cave, and now there are two plans, one is to continue to excavate according to the spiral trajectory and drill out a spiral tunnel leading to the ground." The second is to drill directly above the cave from here, and then dig a shaft to the ground, and then build a lift to pass down. What would you like to do?"

Honggu thought for a while and said: "Let's use the first plan, if you want to use the elevator, you shouldn't drill this spiral tunnel from the beginning, just drill directly from the top of the cave." ”

Mr. Cicada said: "The two plans are not in conflict, this time the spiral tunnel will be dug first, and the elevator shaft can be opened again next time, each with its own benefits." ”

"Well, that's it. Mr. You Guang continued to drive the stalactites to dig a spiral tunnel, and finally drilled diagonally upwards out of the pine forest floor.

The slope of the whole spiral tunnel is not large, so the angle of the stalactite drilling out of the ground is only about 15 degrees, and it will be much easier to walk in it, but it also means that the whole spiral tunnel is very long, and it takes a lot of time to walk down.

"Next, open a small cave under the mining town, put the stalactites in it, and then you can arrange for the mushroom spirit to move in. Mr. You Guang flew over the mining town with the stalactite, and said, "Where do you think it's better to open this cave?"

Yao Chanyi said: "I suggest that Mr. open this cave underground between the mine and the mining town, so that we can transport ore to smelt here." Then dig a tunnel that leads to the Danfang in the town, where there are pills that can't be refined by the Dan furnace, and you can also come here to refine them. ”

"Well, that's a good idea! Mr. You Guang then flew to the mine to the west, where the open-pit was more than one mile deep, and since the nine miles were only three miles thick, the pit could be dug to a maximum depth of two miles, so it was inconvenient to dig any deeper.
