Chapter 266： Tungsten ore discovery

Jia Zhengjin went down and recovered the iron pickaxes as much as possible, blocked the huge cave formed by the explosion of biogas with stones, and then retreated to the ground first.

Recruit 1000 full kobold miners and send the tools down again to allow them to continue digging.

But this time they adjusted the route for them, the steps turned right to 50 or 60 meters, and then turned again to continue towards the veins.

Going back to the ground and waiting for about half an hour, finally a kobold came up and kept calling, informing him that he had dug.

Jia Zhengjin immediately entered the mine and reached the deepest in one breath.

Sure enough, walking down the steps to the end is an unusually rich layer of ore. And very fortunately, in addition to the resource-rich iron ore, copper, gold, and silver mines, there seems to be another color of ore buried deep in it.

But looking at the color alone, Jia Zhengjin cannot distinguish the composition of this ore, so he can only know what it is until the kobold miners successfully dig it.

"Don't worry about other mines first, let me dig directly in that direction!" Jia Zhengjin ordered the kobold miners' troops, "When you find the innermost ore, bring it to me!"

When the kobold received the order, he immediately waved the iron pickaxe in his hand and desperately mined inside.

Four or five hundred kobolds dug together, the scene was quite lively, and the speed was quite fast. The remaining kobolds were responsible for moving the mined ore and stones up and down before the mine was not wide enough, and transported it to the two mines outside.

Jia Zhengjin returned to the land and went to sleep next to him until a kobold came to wake him up.

"Huh?" Jia Zhengjin glanced at the ore handed over from the kobold.

[Tungsten ore] Rare ore with very low content.

Good luck! Jia Zhengjin was immediately full of energy. The haze of the hundreds of miners who lost hundreds of kobolds instantly disappeared.

On the way to Tansandia, he obtained drawings of light bulbs and street lamp manufacturing from a man named St. Thomas. He originally said that this modern item should not be used for the time being. But I didn't expect to find a tungsten mine by accident!

The tungsten wire needed for the production of the bulb is smelted out of tungsten ore.

Although the output of this tungsten mine is not high, but the scale of the city now, it should be enough to fill the street lights!

It's dark after dark, the biggest trouble to date. If you have a street lamp, you can be bright at night!

Of course, electric lights need to be driven by electricity.

But Jia Zhengjin is not worried about this, because he has the manufacturing drawings of magic nuclear batteries! Only one electric magic core, two coal mines and two copper mines can be successfully manufactured!

Of course, he does not understand how strong the magic core battery is. But since it is made of magic core, it is impossible to drive some small toys like the small battery of the previous life, right?

"Dig out the tungsten ore for me!" Jia Zhengjin immediately ordered, "Do not move the silver ore. Wait until the tungsten ore is finished, and then mine iron, copper and gold at the same time!"

The kobold received the order and immediately entered the mine to communicate.

Tungsten mines are really rare. Hundreds of kobolds speed up and dig them out in just one hour.

After all, this kind of mine accounts for only about one-thousandth in the entire underground mine.

There are also more than 400 tungsten mines, all packed into Jia Zhengjin's virtual backpack.

Keep the kobold miners all, put down all the raw meat in their backpacks in their nests and mines, and then let them dig themselves nonstop. Jia Zhengjin only needs to collect the mine once in a while and put food on it!

Returning to the city on a counterfeit dragon, first go to the warehouse to store the mud and stones that are almost full of backpacks in wooden boxes.

When I came out, I remembered that there seemed to be a second-order Warcraft in the stall.

So I took a look at it in the past, and the fire-like Warcraft named Proboscis Bear had already been tamed!

Jia Zhengjin took the proboscis bear out of the stall and asked Wolf to call the female werewolf Vera.

Give the proboscis bear to Vera, so that the three werewolves have a powerful second-order Warcraft.

Two Dakras, a proboscis bear, and the three werewolves who are all good in their own strength, then they can be taken out to hunt some first-order or second-order electric Warcraft and hunt their magic core!

If you encounter other types of Warcraft, you can still grab and bring them back to continue to domesticate and expand the army of Warcraft!

Vera got a second-order Warcraft Proboscis Bear, looking a little surprised. But she did not have any doubts about Jia Zhengjin's decision.

"Early tomorrow morning, the three of you will bring your own Warcraft and go hunting with me!" Jia Zhengjin said to them, "I need more Warcraft and the magic core of the electric system!"

"Yes!!" The three werewolves responded immediately.

Letting the werewolves continue to patrol, Jia Zhengjin rushed to the factory and put the 400 tungsten ores in his backpack into the furnace.

Tungsten ore smelting speed is very slow, and 400 tungsten ore can only smelt 4 tungsten alloys, UU reading www. uukannshu.com is so pitiful!

But now Jia Zhengjin does not want to make alloys, so one tungsten ore is smelted into one tungsten wire, enough to produce 400 tungsten wires!

The formula of the bulb is 1 tungsten wire and 2 glasses. In other words, all smelted here, enough to make 400 bulbs, there is no difficulty in lighting the city! After all, the city is not big now.

The material of the glass is sand, which is very simple, and can be made directly by using stones.

One stone is equal to 10 sands, and 5 sands is equal to one glass.

So when smelting tungsten ore, Jia Zhengjin simultaneously grinded sand on the tool table and then made it into glass.

There are not many materials required for light bulbs, which are relatively easy to make.

However, the material requirements of street lamps are more troublesome!

A street light requires 1 light bulb, 5 iron ingots and 50 cement blocks.

Iron ingots are a rather troublesome part. After all, too many places are needed and the consumption is amazing. And for 400 street lights, you need at least 2000 iron ingots, which is terrifying!

Fortunately, an underground mine has just been developed, together with the open-pit mines around the city, it should be available. The main underground veins have a large probability of outflow, and the amount is relatively large.

As for the cement block, the manufacturing method is simple and the material requirements are not high.

It is the ordinary stones plus clay, and the cobblestone is synthesized on the tool table, and then put into the furnace to smelt it into lime, and then add sand and clay to make cement. Finally, cement blocks are synthesized from cement!

Don’t look at the steps, but it’s actually very simple to make.

So the next most important thing is the problem of electricity. As long as there is enough electricity, the street lights can be lit!

Gradually, there is some modern taste! Jia Zhengjin is full of energy.
