Jia Zhengjin went down and recovered as many iron pickaxes as possible, sealed the huge cave formed by the methane explosion with rocks, and then retreated to the ground.
Recruit 1,000 kobold miners, distribute the tools again, and let them continue digging.
But this time, they adjusted their route. The steps turned to the right for fifty or sixty meters, then turned again and continued toward the vein.
After returning to the ground and waiting for about half an hour, a kobold finally came up and kept calling, telling him that it had been dug through.
Jia Zhengjin immediately entered the mine and reached the deepest point in one breath.
Sure enough, walking along the steps to the bottom is an unusually rich ore layer. And very fortunately, in addition to the resource-rich iron ore, copper ore, gold ore, and silver ore, there seems to be another color of ore buried deep in it.
However, Jia Zhengjin couldn't tell the composition of this ore just by looking at the color, so he had to wait until the kobold miners successfully mined it to know what it was.
"Don't worry about other mines for now. Just dig in that direction!" Jia Zhengjin ordered the kobold miners, "When you dig out the innermost ore, bring it up to me for a look!"
After receiving the order, the kobold immediately waved the iron pickaxe in his hand and started mining inside with all his strength.
Four to five hundred kobolds dug together, and the scene was quite lively and very fast. The remaining kobolds were responsible for carrying the mined ores and stones up and down before the mine was wide enough.
It is transported to two mines outside.
Jia Zhengjin returned to the land and went to the side to have a full sleep until a kobold came to wake him up.
"Huh?" Jia Zhengjin took a careful look at the ore handed over by the kobold.
[Tungsten Ore] A rare ore with very low content.
Good luck! Jia Zhengjin was immediately full of energy, and the haze caused by the big explosion just now that caused the loss of hundreds of kobold miners disappeared instantly.
On his way to the city of Tanzania, he obtained the blueprints for making light bulbs and street lamps from a man named St. Thomas. He originally thought that such modern items should not be used for the time being. But he unexpectedly discovered this
A tungsten mine!
The tungsten filament required for making light bulbs is smelted from tungsten ore.
Although the output of this tungsten mine is not high, the current size of the city should be enough to fill the street lamps!
The darkness after nightfall is by far the biggest trouble. If there are street lights, it can be bright at night!
Of course, electric lights need electricity to drive them.
But Jia Zhengjin is not worried about this, because he has the manufacturing blueprint for the magic core battery! He only needs one electric magic core, two coal mines and two copper mines to successfully manufacture it!
Of course, he didn't know how powerful the magic core battery was. But since it was made by magic core, it couldn't possibly be like the small battery in the previous life that could only drive some very small toys, right?
"Dig out all the tungsten mines for me!" Jia Zhengjin immediately ordered, "Leave the silver mines alone and don't touch them yet. Wait until the tungsten mines are finished digging, and then dig iron ores, copper mines and gold mines for me at the same time!"
The kobold received the order and immediately entered the mine to convey it.
There was really very little tungsten ore, so several hundred kobolds sped up and dug them all out in just an hour.
After all, this type of mineral only accounts for about one-thousandth of the entire underground mine.
There are also more than 400 tungsten ores, all of which are put into Jia Zhengjin’s virtual backpack.
Keep all the kobold miners, put down all the raw meat in the backpack in their lairs and mines, and then let them mine non-stop. Jia Zhengjin only needs to come to collect the ores every once in a while and put in food.
Got it!
Riding the fake dragon back to the city, first went to the warehouse and stored all the dirt and rocks that were almost filling the backpack into wooden boxes.
When I came out, I remembered that there seemed to be a second-level monster in the animal pen.
So I stopped by and took a look, and I saw that the fire-type monster named the Proboscis Bear was already in a tame state!
Jia Zhengjin took the long-nosed bear out of the enclosure and asked Wolf to call the female werewolf Vera.
Give the long-nosed bear to Vera, so that the three werewolves all have powerful second-level monsters.
With two Dakras, a long-nosed bear, and three werewolves who are all pretty good in their own right, we can then take them out to hunt some first- to second-level electric monsters and hunt for the magic cores in their bodies!
If you encounter other types of Warcraft, you can catch them and bring them back to tame them to expand your Warcraft army!
Vera was a little surprised to get the second-level monster Proboscis Bear. However, she did not have any doubts about Jia Zhengjin's decision.
"Tomorrow morning, the three of you will bring your own magical beasts and go hunting with me!" Jia Zhengjin said to them, "I need more magical beasts and electric magic cores!"
"Yes!!" The three werewolves responded immediately.
Letting the werewolves continue patrolling, Jia Zhengjin rushed to the factory and put the 400 tungsten ores in his backpack into the furnace.
The smelting speed of tungsten ore is very slow, and 400 tungsten ores can only smelt 4 tungsten alloys, which is pitiful!
But now Jia Zhengjin does not want to make alloys, so he uses 1 tungsten ore to smelt 1 tungsten wire, which can make 400 tungsten wires!
The recipe for a light bulb is 1 tungsten filament and 2 pieces of glass. In other words, if they are all smelted here, it is enough to make 400 light bulbs, and there will be no difficulty in lighting up the whole city! After all, the city is not that big now.
The material of glass is sand. This thing is very simple and can be made directly with stones.
1 stone is equal to 10 sand, and 5 sand is equal to one glass.
So when smelting tungsten ore, Jia Zhengjin simultaneously ground sand on the tool table and then made it into glass.
Light bulbs don't require many materials and are relatively easy to make.
However, the material requirements for street lights are more troublesome!
A street light requires 1 light bulb, 5 iron ingots and 50 cement blocks.
Iron ingots are quite a troublesome part. After all, they are needed in too many places and the consumption is staggering. And 400 street lights require at least 2,000 iron ingots, which is simply terrifying!
Fortunately, an underground mine has just been developed, and together with the open-pit mines around the city, it should be able to provide it. The main underground mines have a high probability of producing ore, and the amount is relatively large.
As for cement blocks, the manufacturing method is very simple and the material requirements are not high.
Just add ordinary stones to clay, synthesize pebbles on the tool table, and then put them into the furnace to smelt them into lime, then add sand and clay to make cement. Finally, the cement is synthesized into cement blocks!
Although the steps may seem complicated, it is actually very simple to make.
Therefore, the next most important thing is the issue of electricity. As long as there is sufficient electricity, the street lights can be lit!
Gradually, it started to have some modern flavor! Jia Zhengjin was full of energy.
