The time soon came to the first day of August, and it was the day when the Dilong Valley Market opened.

The market half a month ago was messed up by Ning Yuyan, and there were obviously fewer caravans coming to trade this time, and there were almost no women in the caravans.

Even if there is a woman, she is more than half a hundred years old, and when she sees Meng Chen appear, she smears dust on her face, as if she is worried that she will be robbed by Meng Chen.

After casually glancing around, Meng Chen muttered, "It seems that my reputation is completely ruined!" ”

Meng Chen shook his head and left the mountain pass.

The transaction of Dilong Valley was in charge of Ai Li, and Meng Chen hardly needed to worry about it.

In the evening, after Ellie counted the day's trading volume, she reported to Meng Chen with a little frustration: "Lord Lord, the trading harvest of the City of Hope today is thirty percent less than that of a month ago. ”

Meng Chen smiled and comforted, "You have done a good job!" There are four mines in the City of Hope, and there is no shortage of ore and stone. ”

Although he comforted Ellie like this, Meng Chen still attached great importance to the market.

"How can we increase the popularity of the Diryugu Market? Maybe we can hold an auction......" Meng Chen said secretly.

However, it was not only the Dilong Valley Market that troubled Meng Chen.

Meng Chen also received another piece of bad news - one of the veins in the Energy Mine Cave was completely depleted.

Originally, the Energy Mine had two veins, which could produce 3,000 Energy Ores per day.

Now a vein has been completely depleted, and production has plummeted by half every day.

Meng Chen sighed, "The rest of the veins are estimated to not last long. Fortunately, a knock was made from Nanban City, and the City of Hope is not short of gold coins for the time being. ”

The next day, Meng Chen and Alfred led a hundred fourth-order soldiers to the Xuaniron Mine in Shanyu Village again.

Although the Xuaniron Mine is located in the back mountain of Shanyu Village, it is still more than ten kilometers away from Shanyu Village.

Walking along a path more than two meters wide, Meng Chen and the others finally came to a mountain pass.

On the west side of the col there is a stone wall with a blocked mine in the stone wall.

This blocked mine is the Xuaniron Mine in Shanyu Village.

According to Meng Chen's understanding, at the peak of this Xuaniron mine, there were five or six hundred people working at the same time, and the daily output of Xuaniron ore was more than 5,000 stones.

Meng Chen planned to build a mine base here, including three Tier 2 mines, four Tier 2 forts, two guard towers, and a five-meter-high parapet wall.

However, the City of Hope only has 100 Tier 2 miners for the time being, so this construction plan can only be carried out in phases.

According to Meng Chen's plan, the first phase of the Xuaniron Mine only needs to build a second-order mining field, two second-order fortresses, a guard tower and a small section of parapet wall.

Alfred bowed and said, "My lord, after careful investigation, there are no outsiders around. ”

Meng Chen nodded and said, "Very good!"

Then, on the flat ground outside the Xuaniron Ore Cave, Meng Chen gave the order to build a second-order fortress and a second-order mining field.

The two buildings cost a total of 1,800 gold, 600 units of wood (white), 600 units of stone (white), and 60 units of metal (white).

Since it took 36 hours to complete, it was certainly impossible for Meng Chen to stay here forever.

As five marching tents were unfurled, a field camp was set up by the soldiers.

The green marching tent, similar to its surroundings, is eight meters long and four meters wide, and can accommodate ten soldiers temporarily.

Leaving fifty fourth-order soldiers in charge of guarding, Meng Chen, Alfred and the others returned to Dilong Valley first.

In the following five days, Meng Chen went to the Xuaniron Mine several times to issue new construction orders.

Five days later, the first phase of the first mine base in the City of Hope was completed.

This base of the iron mine can accommodate 100 soldiers and 100 miners for a long time.

After the initial completion of the mining base, Meng Chen dispatched skilled miners from the energy mine to go to the Xuaniron mine to excavate the Xuaniron ore.

As for the Energy Mine, it will be taken over by 100 newly trained Tier 1 miners.

When 100 Tier 2 miners are stationed in the Darkiron Mine, 500 tons of Darkiron Ore can be mined per day.

500 tons of black iron ore are smelted in a blacksmith to obtain about 350 units of green quality metal.

350 units of Green Metal, which cost 14,000 Gold if purchased through the Market; If you sell it directly to the market, you can get 700 gold coins.

This is the income of a Tier 2 mining farm, if you have 300 Tier 2 miners and run three Tier 2 mining farms at the same time, the income from selling Darkiron alone can reach 2,100 gold coins per day.

After a little estimation, Meng Chen's eyes immediately lit up with golden light, "This is only one Xuaniron mine, once all four mines are developed...... Hiss! The daily income can top two or three energy mines! ”

Therefore, Meng Chen decided to go all out to develop the remaining three mines in the next period of time.

While Meng Chen was busy building the mine base, Ning Yuyan, who was imprisoned, became more and more anxious.

After several meetings, Meng Chen found that Ning Yuyan was still unwilling to tell the truth, so he handed over Ning Yuyan's interrogation to Ellie.

On this day, Meng Chen received a report from Ellie, "Lord Lord, that woman is trying to commit suicide!" ”

"Suicide? What's going on? Meng Chen said in surprise.

Ellie's face was slightly red, and she lowered her head and whispered, "Just go and see!" ”

Accompanied by Ellie, Meng Chen walked quickly to the blacksmith shop.

When Meng Chen walked into the storage room, he immediately found that the layout here seemed to be very different from before.

The walls were covered with straps, leather whips, candles, and other items, while Ning Yuyan's body was covered with a large number of strangulation marks and whip marks.

Ellie seems to have taken advantage of Meng Chen's absence to do a lot of indescribable strange things to Ning Yuyan.

Meng Chen glanced at Ellie strangely, and asked with some hesitation, "These ......"

Ellie pretended to be calm and said, "Her subordinates are interrogating her. ”

"Uh...... All right! ”

Anyway, it was Ning Yuyan who was bullied, and Meng Chen didn't care about it.

At this time, Ning Yuyan took the initiative to control the true element in her body and gave up resisting the erosion of the giant beast's venom.

Under the erosion of the poison, wisps of dark green marks spread in Ning Yuyan's body.

If he is not treated, it may not be long before Ning Yuyan will be poisoned.

Knock knock!

Meng Chen knocked on the cage and sighed: "As an immortal cultivator, Miss Ning has hundreds of years of longevity to enjoy, so why bother to kill herself?" ”

After hearing Meng Chen's voice, Ning Yuyan opened her eyes with great difficulty, first glared at Aili fiercely, and then said weakly to Meng Chen: "That woman...... Insulting me too much, the slave family would rather ...... One is dead! ”

After speaking, Ning Yuyan closed her eyes, retracted into the corner and waited for death.

Meng Chen patted his forehead and muttered, "Ning Yuyan can't die, at least she can't die until you ask her where she came from!" ”

Thinking of this, Meng Chen hurriedly left the blacksmith shop.
