Chapter 265: Big bang underground

The disadvantage of open pits is that the mines are scattered and the collection rate is very low.
Now Jia Zhengjin needs more mines to build new buildings!
So he needs a new mine, and it is better to be a resource-rich underground mine!
The underground mines are relatively dense and the collection rate is also very high. Of course, the efficiency is unmatched by the open pit mine!
Of course, in the absence of minecart and miner's lamp, the mining difficulty is slightly greater.
Jia Zhengjin brought materials full of backpacks early in the morning, and then rode a fake dragon on the road alone. Turn on the ability to find mineral veins, and scrutinize the area slightly away from Holy Dragon City.
Open pit veins are easy to find, because as long as the skills are turned on, there will be a variety of colorful vein veins in front of you. But the underground veins are a little more difficult. After all, they are buried deep underground, and even if you open the skills, you may not be able to see them. Some of them can be seen, but they are only small and very small light spots, which will be missed if you pay little attention.
Fortunately, Jia Zhengjin had good luck. After spending half a day, he finally found a spot full of tiny light spots.
This vein is about 11 kilometers northeast of Shenglong City, the distance is quite far!
However, there are no large ferocious alien animals and Warcraft nearby, only some relatively gentle herbivorous and insectivorous groups exist. Work safely here!
The ore veins are deep, and Jia Zhengjin can only barely see the densely colored spots of sesame size when he landed on the ground. According to preliminary estimates, it is at least five or six hundred meters above the ground.
Before starting mining, of course, you must be fully prepared! Moreover, it is impossible for Jia Zhengjin to go to mine alone, so the materials prepared earlier in the backpack come in handy.
Because the minerals are more abundant, such underground mines are five or six times the sum of all the open-pit mines that I found myself before! And Jia Zhengjin also needs to acquire minerals more quickly.
So he directly built a level 1 kobold den in the open space, and then built a mine near the den.
Immediately afterwards, 500 kobold miners were recruited with raw meat and set up in the mine. Also recruit 500 to stay in the nest.
Immediately after the recruitment was completed, 1000 kobold miners were gathered in the open space. He took the premise from the virtual backpack and took the iron pick and stone shovel manufactured by the 500 kobold artisans in the factory one day, and fell to the ground to form a hill. The kobold said: "Receive an iron pick and a stone shovel, and wait for my order!"
All the kobolds acted immediately, and stepped forward to get it at this tool hill. After getting two tools each, they stood in the open space in front of Jia Zhengjin.
Looking at the dense kobolds in front of him, Jia Zhengjin ordered loudly: "Starting from this area, use a stone shovel and iron pickaxe to dig down in steps and descend to the mining area over there. The team went down, leaving a gap of dozens of kobolds in the middle. Well, act now!"
Upon receiving the order, the kobold miners were immediately busy, lining up in a neat queue and digging down. They dug three squares, then dug two squares forward, then dug one square down, and then dug two squares forward. In this way repeat indefinitely, creating a road to the underground.
Because the ground is dark and there is currently no lighting equipment such as a miner's hat, so only some kobolds can hold torches first.
The team is not moving fast, it can be estimated that it will take quite a while.
Jia Zhengjin simply sat next to a large tree, closed his eyes and rested.
The speed of the kobold miner's collection is quite amazing, coupled with the iron picks and stone shovel produced by the system, the head kobold takes the lead, quickly digs down the pit, and then starts to lean forward in a stepped manner.
Listening to the tinkling sounds in the ears, watching the kobolds outside send the earth and stones to the ground one by one, and pile them up to the spacious open space. Jia Zhengjin leaned on the tree trunk with satisfaction, preparing to sleep a little first.
Wait until the kobolds dig through the path and reach the mine veins, then go down and check the overall situation.
During this time, he was very tired every day. Various things reduced his rest time. Especially when the elves come to the city, because of customs, it is inevitable that there will be some small friction with humans. Just to appease the parties, he was already exhausted. There are only five or six hours left in bed every day.
Therefore, in a quite sleepy situation, he fell asleep unconsciously.
I was having a dream, and suddenly there was thunder and thunder in my ears, and then I felt the earth tremble a few times!
Jia Zhengjin was instantly awakened and looked around blankly, "Has an earthquake?"
"Aoao~~" The kobolds, who were not far away from the rocks and dirt, all called desperately at him.
The kobolds have piled up behind him, and Jia Zhengjin hurried over to collect the amazing amount of mud and stones into a virtual backpack. Then the kobold miners asked, "What's the situation?"
"Aoao~" The kobold howled desperately at the mine.
Did something happen below? Wouldn’t it be dangerous underground creatures encountered? Jia Zhengjin was immediately armed, holding a gold shield, and lifted the spear of gold flat and jumped down: "Lighting!"
As soon as the kobold came down, UU Reading www.uukanshu.com raised his torch and walked in front of him.
With the faint light of the torch, Jia Zhengjin, led by the kobold, moved down the steps that could not see the bottom.
He felt strange. Except for the hundreds of kobolds standing outside, there was no movement from those who dug down all the way?
Leaning down and walking continuously, at least more than a thousand meters or so, when he was almost exhausted, the kobold who led the way made a sharp cry: "Ao~o~"
Jia Zhengjin immediately followed, and was surprised to find that the steps ended here, and there was a huge hole in front.
Could it be naturally formed? Jia Zhengjin approached the past and felt that the temperature of the nearby soil and stones was quite high. The probe looked down, suddenly dumbfounded!
In a huge circular hole with a complicated shape, the corpses of kobolds lie in a row. Every kobold is incomplete, buried in mud and stones. The scorching breath rushed across the face like a stove. But there was no flame or anything that could heat up inside.
"Huh?" Jia Zhengjin looked around, studied for a while, and finally found the reason!
Everything in the pothole is like the situation after the big bang. And he could smell a special smell faintly. Looking back carefully, it seems to be biogas! However, probably the big bang just used up all the biogas, so only a trace of stock is not enough to make a second big bang!
Unlucky! Jia Zhengjin looked at the steps approaching the underground mine and was speechless! Unexpectedly, these kobolds accidentally dug a natural marsh gas vein. Whether it is dying or not is now using torch lighting, so it caused a terrible explosion. The biogas was completely exhausted, and five or six hundred kobold miners died, and huge pits were blown out here!
