At the foot of the Obsidian Mine in Ningjing County, a group of elderly miners were lining up honestly at this time. They had been in the dark mine for a long time, and they were not quite used to the sunlight outside.

When these miners were bought back as slaves, they were all young men in their twenties. After ten years of mining in the mines, they were all very old.

After ten years of hard work in the mine, they are still alive today, and they have outperformed 50% of the miners.

"Everyone is lined up, Mr. Zhang is kind, allows you to be free, and gives each of you consistent money so that you can spend your old age peacefully."

A black water army stood beside the team and shouted loudly, while the other black water army registered the name of each miner, pressed his handprint, and then issued the consistent money.

After each miner received the money, they would kowtow to the Black Water Army with the heavy copper coins in their hands.

At this time, the soldiers of the Black Water Army will tell everyone that this is the favor of Zhang Gongzi.

At the same time, the miners in the mine can also take an extra day off today and go outside to bask in the sun. For them, sunlight is also a luxury.

"It turns out that we can really leave freely after ten years. I thought we would die in this life."

"It's not that, you see, there is still money to send!"

"One thousand yuan per person, so much money can buy several daughters-in-law."

"Take it down. I still want several daughters-in-law. You are small and don't have any flesh all over your body. You can pee on your shoes. Can you still be convinced? Don't make the old man next door cheap."

"With so much money, I'll buy some fat to make up my body, and maybe I'll be able to flutter a couple more times."

People always need a little hope, so as to have the courage to persevere in desperate situations.

Since Zhang He took over the mine, he has begun to eliminate the old and weak miners who remained in the past and give certain monetary subsidies.

Now, for Zhang He, this money is just a drop in the bucket, but it can allow these miners to spend their old age peacefully.

At this moment, Zhu Zheng brought back a group of young and strong slaves from outside to supplement the personnel gap in the mine.

"Jush Chang is back!"

A soldier immediately greeted him, and Zhu Zheng has now risen to the top, and is responsible for managing this obsidian vein.

"You register these 200 people and send them all into the mine."

"OK!"

Zhu Zheng left as soon as he gave an order. The soldiers led the 200 slaves to register one by one, each handed a set of tools, and sent them into the mine after a few words.

These 200 people were sent into the dark mine at first, and they were still a little uncomfortable and a little confused.

Only one of the chunky miners looked a little different. His eyes were no longer cloudy. He threw the mining tools in his hand and walked into the depths of the mine alone.

The chunky miner walked alone in the mine, without lighting, but he was still able to move quickly through it, and when he passed some miners, they could only feel a breeze.

After years of excavation in the obsidian mine, there are many branches.

The chubby man walked to the end of a mine at this time. The spiritual energy here has become thin. Obviously, this is an abandoned mine.

After walking in vain, the short and fat man was not very happy. He slammed a fist on the stone wall, and the stone wall suddenly collapsed. The power of this punch was at least a foundation-building cultivator.

The chubby man walked back a mile, grabbed a miner, and tortured him for a while. According to the miner's confession, he drew a brief map, which marked the approximate direction of each mine.

"Is it like this?"

The chubby man took the drawn map to the miner and asked him to confirm it.

"Yes! Yes! It's like this, can I go?"

The captured miner shivered, and the two miners who were with him were killed on the spot by the immortal master, and he was the only one left to be tortured here for information.

"Have you seen this kind of ore?"

The short and fat man took out a purple-red obsidian at this time. When the ore was taken out, the temperature in the mine also increased a little.

"No...I haven't seen it."

The miner shook his head in confusion.

The chunky man was too lazy to talk to an ant at this time, and with a wave of his palm, the miner's head shattered.

Next, he arbitrarily caught two miners, tortured the terrain, and perfected the map of the entire mine structure.

With the topographic map in hand, the next step is to investigate the mines one by one.

His mission this time was to find the purple-red obsidian ore and find out the reserves of this ore without disturbing the snake. Other matters had nothing to do with him.

Apart from the miners, there is no other black water army in this mine, so he can do whatever he wants.

At the speed of the immortal cultivator in the foundation-building period, the exploration of a mine can be completed very quickly.

Two days later, the chunky man appeared in a hot mine.

After two days of investigation, this mine has the greatest chance of hiding purple-red obsidian.

Yesterday, he had come to this place for preliminary exploration. This is a rich mine, and high-quality obsidian can be seen everywhere on the two walls of the mine.

It's just that the temperature here is too high, and ordinary mortal miners can't stay here for too long, and the mines only stop at the front.

The short and fat man walked to the end of the mine tunnel. The stone wall in front of him was inlaid with a lot of obsidian, and he could drop a piece with just a pickaxe.

It's just that the temperature here is too high, and even a late foundation-building cultivator like him is sweating all over his forehead at the moment, and he can't even wipe it off.

The chubby man could only put out a shield to keep out the heat, which made him feel much more comfortable.

If this mineral vein contains purple-red obsidian, it is likely to be in it.

The short and fat man took out a flying sword and slashed in front of him, but the rock in the mine was too hard, so he cut more than ten feet deep. There were a lot of gaps in the flying sword, and it could no longer be used. .

The advancing distance of more than ten meters was still surrounded by dense obsidian, but none of the purple-red obsidian he wanted to find was found.

The chubby man looked at the stone wall in front of him, and could only put away the flying sword in his hand and take out an earth escape talisman.

The price of this earth escape charm is not cheap. It can only be made by a monk who can use the earth escape technique. It is difficult to obtain. He only got two in total.

Use the Escape Talisman to temporarily grant yourself the Escape ability.

The short and fat man slapped the Earth Escape Talisman on his chest, and instantly a yellow light enveloped him in it.

Then he slammed his head into the cave wall in front of him, and the whole person disappeared into the stone wall and disappeared.

Protected by a yellow light outside, the chubby man swims in the rocks as freely as a fish in the water.

He moved forward along the obsidian vein, and the dense obsidian he saw along the way was getting higher and higher.

The shield he first sacrificed was no longer able to protect him. Fortunately, before he came, the elders of the clan had given a magical tool made of thousands of years of mysterious ice - the mysterious ice umbrella.

As soon as this magic weapon was sacrificed, a coolness enveloped the body immediately.

But this coolness wouldn't last long, and as he continued on, it started to get hotter and hotter.

Across the Xuanbing Umbrella magic weapon, he still felt dry, as if he was in an oven.

However, he did not back down because he had already seen hope, and now there were some purple lines on the obsidian that he could see.

I believe that if you go further, you will be able to see the real purple-red obsidian.

However, there are unforeseen circumstances, and people have good and bad luck. Although the Xuanbing Umbrella magic weapon refined by the thousand-year-old Xuanbing is good, it is not a magic weapon after all.

"Crack!"

Cracks began to appear on the mysterious ice umbrella and quickly spread around.

"not good!"

The chubby man turned pale in shock, and immediately turned back and walked back.

It was just too late. At this moment, the Xuanbing umbrella was densely covered with cracks, and it finally shattered with a "click" sound.

"Ah ah ah..."

With the shattering of the mysterious ice umbrella, in the depths of the mine, after a shrill scream, it finally returned to peace, and there was only a charred corpse left.

With the passage of time, after tens of thousands of years, this scorched corpse may become a fossil, and it may become a precious specimen for the study of ancient human beings.

At the moment when the chubby man died, in the faraway territory of Wu Kingdom, the Fan Family Ancestral Hall, there was a hall of several hundred square meters, and there were countless flickering lights in the hall.

Suddenly, the flame of one of the lamps flickered and instantly annihilated.

"No, Fan Xian is dead, you continue to guard here, I will report to the elders."

A guard trotted out of the ancestral hall.

"Report to Elder Jing, Fan Xian's soul lamp has gone out."

"Well, I see, back off."

The elder Jing, who was meditating inside, had a calm tone and didn't feel too surprised, with a slightly disappointed look on his face.

When the visitors retreated, Elder Jing said to himself: "It seems that the foundation is still too weak, that's all, let's send a Jindan to investigate."

Elder Jing muttered to himself, and sent a message to fly into the distance.

………………

Zhang He didn't know anything about what happened in the obsidian mine. He has now returned to Ningjing County from Dadu.

At the moment, he is being led by Huya to visit the steelmaking plant that has just been built.

For the convenience of transportation, this steel mill was built directly next to the iron mine.

"Look, son, this is a large steel-making furnace, and the fuel used is coal.

This steelmaking furnace is a super-large instrument with 36 formation runes engraved on it, which are used to control the temperature of the furnace and to purify and remove impurities. "

Huya enthusiastically introduced the entire process of making steel to Zhang He. The steelmaking method here is completely different from Earth technology, and it is a completely different path.

The iron ore is refined into steel by means of the array method and some refining methods.

"In this building connected to the steel-making furnace, there are more than 1,000 spirit gathering arrays, which are connected together to form a super-large spirit gathering array, which provides spiritual power to the steel-making furnace through rune connections.

These more than 1,000 spirit gathering circles are all independent structures. If some of them are broken, it will not affect the normal operation of the steelmaking furnace. "

Zhang He had already noticed that aura was constantly gathering in the sky above this super-large spirit gathering formation.

Afterwards, Huya led Zhang He to inspect the iron mine.

This iron mine is relatively shallow, and it can be mined directly in the open pit without digging holes.

The mining method is still relatively primitive, that is, blasting it with gunpowder first, then hiring a large group of miners to knock it with a pickaxe, pick it up with both hands, and lift it with a wooden frame. side.

The only more advanced aspect may be the zombie car that transports ore.

There is a road between the mine and the steelmaking furnace. In the absence of large-scale machinery and equipment, transporting iron ore back and forth every day is also a big project, enough to cause a large number of miners to vomit blood and die.

In addition, transporting coal from other places to the steel plant also requires a large group of zombies to pull carts.

Before trains were made, zombies were still an indispensable means of transportation.

In the territory of Blackwater County, there are still a large number of working zombies.

This time, 10,000 zombies were specially transferred from Heishui County in order to set up a steel mill.

These zombies screamed and happily pulled up their carts and ran back and forth on the path, rolling up smoke and dust.

Sometimes they run too happily and can't stop the car, and together with the zombie car and iron ore, they will fall into the tumbling steel-making furnace and become a small amount of impurities in the steel.

Zombies do the heaviest work during the day, and they only need to feed some dead grass stained with pig blood after get off work every day.

As a big project, steel mills still employ thousands of workers in addition to zombies.

More than a thousand of them were specially recruited from Blackwater County.

Because the new generation of young people in Heishui County came out of the school, they are literate and literate. When it comes to some more complicated operations, it is easier for people with a certain cultural foundation to understand.

At present, this steelmaking furnace can produce about 2,000 kilograms of steel per day on average. Although it is still far from the steelmaking furnaces on the earth, it is already very advanced in the Zhou Dynasty.

And the quality of the steel produced is much better than the iron produced by the local method.

If it is used to make swords, it should be able to compare with those hundred-forged swords.

After the railway is completed in the future, it can also be transported to other places for sale.

In the world of ordinary people, salt and iron are the two most expensive resources, and as long as one of the two is mastered, it represents a lot of wealth.

"Sir, this steel-making furnace is only the first one, and it is an experimental one. We are now planning to build the second steel-making furnace."

"Yeah! Well done." Zhang He patted Hu Ya on the shoulder with certainty.

"However~www.wuxiahere.com~ Your main task is to do research, and for the follow-up preparations, you only need to leave a few people here to be responsible for guidance.

You have more things to do, such as large transport vehicles made of steel.

For example, the production of spiritual tools, or in the longer term, psionic cannons, flying boats and even flying battleships..."

Hearing Zhang He mention this, Hu Ya's eyes became brighter and brighter, his hands clenched into fists, and he was uncontrollably excited.

To delve into the top technology in the immortal world and refine the most colorful treasures in the immortal world. This is the life he wants.

"Okay! I'll organize the staff now! I promise to see our transporter running soon."

Hu Ya said goodbye, and went to greet the staff.

For people who like to engage in technology, it is the greatest satisfaction to be able to devote themselves to the career they like.

It doesn't even matter if you have money or not, it's purely a hobby!
