Chapter two hundred and sixty fifth underground explosion
The disadvantage of open pit veins is that the mines are relatively scattered and the collection rate is also very low.
Now Jia Zhengjin needs more mines to build new buildings!
So he needs a new mine, preferably an underground mine with rich resources!
The minerals in underground mines are relatively dense, and the collection rate is also very high. Of course, the efficiency is unmatched by open-pit mines!
Of course, without a minecart or a mining lamp, mining is a little more difficult.
Jia Zhengjin packed a backpack full of materials early in the morning, and then rode the fake dragon on the road alone. He activated the skill of finding mineral veins and carefully explored the area slightly away from the Holy Dragon City.
Open-pit mines are easy to find, because as long as the skill is turned on, a variety of colorful veins will appear in front of you. But underground mines are a little more difficult. After all, they are buried deep underground, and you may not be able to see them even if you turn on the skill.
Some things that can be seen are only very small light spots, and you will miss them if you don't pay attention.
Fortunately, Jia Zhengjin was lucky. After spending half a day, he finally found a location full of tiny light spots.
This mineral vein is about 11 kilometers northeast of Shenglong City, which is quite a distance!
However, there are no large ferocious alien animals or monsters nearby, only some relatively docile herbivorous and insectivorous groups. You can work with peace of mind here!
The veins are so deep that even when Jia Zhengjin landed on the ground, he could barely see densely packed light spots of various colors as big as sesame seeds. According to preliminary estimates, they were at least five or six hundred meters above the ground.
Of course, you must be fully prepared before starting a mine! And it is impossible for Jia Zhengjin to go mining alone, so the materials prepared earlier in the backpack came in handy.
Because minerals are relatively abundant, such underground mines are five or six times the sum of all the open-pit mines he has found before! And Jia Zhengjin also needs to obtain minerals faster.
So he directly built a level 1 kobold lair in the open space, and then built a mine next to the lair.
Immediately after that, use raw meat to recruit 500 kobold miners and set them up in the mine. Recruit another 500 to stay in the lair.
After the recruitment was completed, he immediately asked 1,000 kobold miners to gather in the open space. He took out the iron picks and shovels made by 500 kobold craftsmen in the factory the day before from his virtual backpack, and fell to the ground to form a hill.
The kobold said: "Each get an iron pick and a stone shovel, and then wait for my order!"
All the kobolds immediately took action and stepped forward to get from the tool hill. After each got two tools, they stood in the open space in front of Jia Zhengjin.
Looking at the densely packed kobold troops in front of him, Jia Zhengjin ordered loudly: "Start from this area, use stone shovels and iron picks, dig down in steps, and go all the way down to the mining area. Form a line.
The team moves downwards, leaving a gap in the middle for dozens of kobolds to walk together. Okay, act now!"
After receiving the order, the kobold miners immediately got busy and lined up neatly to start digging holes. They dug three squares, then dug two squares forward, then dug one square downward, and then dug two squares forward. It goes on indefinitely.
Repeat to create a path underground.
Because the underground is dark and there is currently no lighting equipment such as miner hats, we can only let some of the kobolds hold torches first.
The team does not move down very quickly, and it can be expected that it will take quite a while.
Jia Zhengjin simply went to the side and sat under a big tree, closed his eyes and rested his mind.
The speed at which the kobold miners collected was quite astonishing. With the iron picks and stone shovels produced by the system, the kobolds at the head took the lead, quickly dug the hole downwards, and then began to move forward in a stair-step manner.
Listening to the tinkling sound in his ears, he watched the kobolds outside sending the soil and stones out of the ground one by one and piling them into the spacious open space aside. Jia Zhengjin leaned against the tree trunk with satisfaction and prepared to take a short nap first.
Wait until the kobolds dig the path and reach the mineral vein, then go down to check the overall situation.
During this period, he was very tired every day, and various things reduced his rest time. Especially when the elves came to the city, due to customs, they would inevitably have some minor frictions with humans. Just appeasing all parties, he had already been
I am so tired. I only have five or six hours of sleep left every day.
Therefore, in a very sleepy situation, I fell asleep unconsciously.
I was having a sweet dream when suddenly there was a deafening thunder in my ears, and then I felt the ground shaking several times!
Jia Zhengjin was instantly startled and looked around with a confused expression, "Is there an earthquake?"
"Ouch~~" Not far away, the kobolds who were collecting rocks and soil outside were all yelling at him desperately.
These kobolds had piled up behind them. Jia Zhengjin hurried over and put the staggering amount of soil and stones into his virtual backpack. Then he looked at the kobold miners and asked, "What's going on?"
"Ouch~" the kobold howled desperately toward the mine.
Could it be that something happened below? Could it be that he encountered some dangerous underground creature? Jia Zhengjin immediately got fully armed, held a golden shield in his hand, and jumped down with a golden spear raised: "Illumination!"
Immediately a kobold came down, held up a torch and walked in front of him.
By the faint light of the torch, Jia Zhengjin moved down the steps that could not be seen to the bottom under the leadership of the kobold.
He found it strange that, except for the hundreds of kobolds standing outside, there was no movement from those digging all the way down?
He kept walking downwards at an angle, at least for more than a thousand meters. Just when he was almost exhausted, the kobold leading the way let out a sharp cry: "Ouch~Ouch~"
Jia Zhengjin immediately followed, and was shocked to find that the steps ended here, and there was an extremely huge pothole in front of him.
Could it be a natural formation? Jia Zhengjin approached it and felt that the temperature of the soil and rocks nearby was quite high. When he looked down, he was stunned!
The huge circular pit with a complex shape was filled with corpses of kobolds. Every kobold was mutilated and buried in mud and stones. The hot breath hit his face, like a furnace. But inside there was
There is no flame or anything that generates heat.
"Huh?" Jia Zhengjin looked around, studied for a while, and finally discovered the reason!
Everything in the pit looked like the situation after the big explosion. And he could faintly smell a special smell. Thinking back carefully, it seemed to be methane! But it was probably because the big explosion just now consumed all the methane, so
There is only a trace of stock left that is not enough to create a second big explosion!
What bad luck! Jia Zhengjin was speechless when he saw that he was approaching the steps of the underground mine! Unexpectedly, these kobolds unexpectedly dug a vein of natural biogas. They were so lucky that they were now using torches for lighting, which triggered a horrific explosion.
The methane gas was exhausted, all five to six hundred kobold miners died, and a huge hole was blown out here!
