Chapter 1733

"Low output is a flaw!"

Lu Chen looked at the digging tools scattered all over the ground, and asked again, "The enemy has occupied the mine, so there are probably many people digging, but what about them?"

"The enemy was defeated, and the mines belonged to our people. If the miners of the enemy still haven't run away, are they waiting for us to have supper?"

Lian Jia laughed.

"So, you brought 100,000 people here just to let them be miners?"

Lu Chen asked again.

"The output of the mine is low, 10,000 people are enough to be miners, and the remaining 90,000 people are stationed here to prevent the enemy from sending small groups of troops to attack."

After Lian Jia said it, without wasting time, he selected 10,000 warriors from among the 100,000 warriors to serve as diggers.

Then, the 10,000 miners followed Lian Jia into the mine, and Lu Chen also led the fanatical army to follow and go deep into the mine.

This huge mine goes deep into the bottom of the mountain, with winding passages and many forks, making it easy to get lost.

But Lian Jia was familiar with the Wuwen Mine, and he was familiar with the road, leading the crowd around the passage, but the pace was not slow at all.

In less than half a stick of incense, everyone went a thousand miles deep underground and came to a huge mine.

This huge pit with a radius of hundreds of miles is full of potholes, traces of excavation everywhere, and a large number of abandoned excavation tools everywhere.

Lu Chen inspected the surface of the mine pit, and found that the soil and sand here were extremely hard. He grabbed a small stone at random, and it took real energy to crush it.

It is conceivable that the soil of the mine pit is solid, many times stronger than black iron, not to mention that ordinary people can't dig it, even the venerable can't dig it.

"These digging tools?"

Lu Chen grabbed a shovel and found that the body of the shovel was extremely heavy, and the head of the shovel was extremely sharp. "The quality of this thing is almost as high as that of a holy weapon. I think it can even dig black iron."

"These things are all made of special materials, and they are specially used to dig the Wuwen Mine, otherwise the soil here would not be able to be dug at all."

Lian Jia said.

"What are you waiting for?

Hurry up and start working, I want to see what the Wuwen Mine looks like? "

After spending so much time inside, Lu Chen urged him.

Lian Jia then directed the 10,000 miners to use those abandoned digging tools to start mining immediately.

The output of Wuwen ore in this mine is small, and the geological conditions of the mine are too hard, which makes the excavation quite slow. Even if 10,000 people dig at the same time, it is not possible to dig Wuwen ore immediately.

It took a long time to dig for a stick of incense before someone dug up a small piece of black-patterned ore, the size of a fist, and it was black. At first glance, it looked like a lump of coal.

"Give me!"

Lu Chen brought the piece of Wuwen ore over, it was a bit heavy, about ten kilograms.

The entire piece of black ore is covered with countless fine lines, with some kind of special energy attached to the lines.

This kind of energy is extremely thick, completely different from the energy of spirit stones, it cannot be absorbed by the human body, nor can it be used by the human body.

Lu Chen then showed the black-grained stone to Fat Long, but secretly transmitted the sound to Fei Long: "The black-grained stone has special energy, do you think it can be used on castings?"

Feilong looked at the Wuwen Stone carefully for a moment, and then replied to Lu Chen: "This is the energy of the earth system, and it can only be mixed with earth and stone to cast it. It is mainly used for buildings, and there are not many other uses.

What I need for casting is the energy of the animal core, and the energy of the gold system can also make do, but the energy of the earth system is simply useless. "

"It's a pity that such a rare and awesome ore can't be used."

Lu Chen was a little disappointed, such a good resource could not be used, but could only be used to build a house, what a waste of money.

"Brother, I have an idea, we can use Wuwen Ore to refine into Wuwen Sand, and then mix it with black iron to cast it into defensive equipment.

For example, if we cast a wall of earth, pull it out during a defensive battle, and place it directly in the battle formation, it is definitely better than Gao Lao's garbage iron hoop formation! "

But Feilong came over by sound transmission like this.

"Earth wall?"

Lu Chen froze for a moment, then thought about it.

"Obstacles such as earth walls and mounds, as long as they play a defensive role, they can be anything."

How did Feilong transmit the sound?

"Your suggestion is good, this thing is worth doing!"

Lu Chen's eyes lit up, and he thought of a better idea, "Leave it to Yu Li, let him do it, and add another layer of strong defense to our army!"

"I'll go. Yu Li is not a civil engineer. If you let him be a mason, will he be able to handle it?"

"There is no one in the entire legion to do civil work, so I can only leave it to Yu Li. He is in charge of the battle formation, and he is responsible for the defense of the battle formation."

"Oh, by the way, we forgot one thing. If you want to make a big effort on the earth system defense line, you must at least have a lot of Wuwen ore. Just this small piece of Wuwen ore is probably enough to cast a stone table." Not enough."

"Calm down, isn't there tens of thousands of people mining here, why are you afraid that you can't get a lot of Wuwen mines?"

"That's not necessarily true. You see, the soil here is as hard as a holy shield, and their digging speed is as slow as a tortoise. The output of the Wuwen mine underneath is very small. When they dig up the amount we need, we don't know that it will be a year of monkeys." gone."

"How much Wuwen mine do you estimate we need to build an earthen wall?"

"At least 100 million catties!"

After hearing Feilong's estimate, Lu Chen turned around and asked Lianjia: "How long will it take to dig 100 million catties of Wuwen mine?"

"It can be as fast as three to five years, and as slow as ten or eight years."

Lian Jia suddenly thought of something, so he asked, "Lord Lu, do you need Wuwen Mine?"

"Yes."

Lu Chen responded.

"Master Lu, the Wuwen Mine is a special building material, which is demanded by the higher-ups of the human race. All the output here must be turned in, and you can't take it."

Lian Jia said quickly.

"It will take three to five years at the fastest to dig out 100 million catties. The daylilies are cold, so it's useless to give them all to me."

Lu Chen chuckled, took back the Wuwen Mine in Feilong's hand, and threw it to Lian Jia, "I don't want it anymore, you can hand it all over."

"Lord Lu, I'm really sorry, this is the rule of the higher-ups of the human race, and I dare not play favoritism."

Lian Jia looked apologetic.

"It's okay, go get busy, I'll walk around."

Lu Chen said.

"Master Lu, I will accompany you for a walk!"

Lian Jia said.

"I want to pull Xiang, you also pull with me?"

Lu Chen frowned.

"ah?"

Lian Jia was taken aback, unable to understand, "We have all cultivated to this level, our physical bodies are extraordinary, we have not eaten grains for a long time, and directly extract energy from spiritual energy to survive, basically there is nothing to pull.

For example, I haven't pulled anything for hundreds of years. How can Mr. Lu have something to pull? "

"I have a lot of roundworms in my stomach, can't I pull a batch out?"

Lu Chen rolled his eyes and said angrily.

He refused to follow him cheaply, and obviously wanted to do things alone, and Laxiang was just an excuse.

Lian Jia actually believed it, and he also accepted it.

This cheap fighter is good at fighting, but his brain is not very good, and he is not good at all.
