Just as Meng Chen was scolding, a miner made a new discovery, "Lord Lord, come and see!" ”

Meng Chen was shocked, and hurriedly walked out of the pit and came to the miner's side.

The miner was seen holding a rock with a white stone embedded in the light gray surface of the rock.

"What is this?" Meng Chen was surprised.

The miner shook his head and replied, "My lord, I don't know what it is!" But for sure, it's a rare ore! ”

Meng Chen took the rock in the miner's hand and muttered with a puzzled expression: "There are a lot of rare ores in the game, such as Mithril Ore, Gold Concentrate, Aojin Ore or something...... What kind of ore is this white stone? If you don't know how to use it, even if it's a rare ore, it won't be of much use! ”

At this moment, an electronic synthesis sound sounded in Meng Chen's mind, "Ding Dong!" Player Meng Chen found energy ore, do you want to recover it? ”

"Energy ore? Can it be recycled? ”

Meng Chen looked surprised, and then immediately said, "Recycling!" ”

A faint white light flickered, and the white stone embedded in the rock surface disappeared silently.

A message popped up from the light curtain in Meng Chen's mind, "Energy Ore (White) -1, Gold Coin +1!" ”

"White quality energy ore? Can it be recycled directly into gold coins? This is the rhythm of getting rich! Meng Chen said ecstatically.

Although this energy ore is only the size of a ping-pong ball, it can be directly recycled into 1 gold coin, which is worth many times more than other resources.

For Meng Chen, this mine that can produce a large amount of ore is simply a gold mine in the game!

Meng Chen ordered the five miners: "Mine energy ore with all your might, it's that kind of white stone!" ”

"Yes! Your Lord! The crowd responded in unison.

Subsequently, Meng Chen left the mine and gave the order to build a mining farm at the exit of the mine.

"Gold -100, Wood (Gray) -100, Stone (Gray) -100, Metal (Gray) -10, start building a mining farm (Tier 1)! After 24 hours, the construction was completed! ”

"Five miners is too few, let's go back to the City of Hope first and bring the other miners with us." Meng Chen said secretly.

The pale blue sun was about to reach its highest point, and Meng Chen ordered 5 swordsmen and 5 archers to be stationed at the exit of the mine.

Meng Chen, on the other hand, led 5 other swordsmen and 5 archers back to the City of Hope on the west side of the river.

After returning to the City of Hope, Meng Chen summoned 10 civilians from today and sent them to the academy to train them to become miners.

Then, Meng Chen led the remaining 17 miners in the city to the cave in the rock rift valley again.

At this time, Meng Chen didn't even want to waste half a day, and now there was only one thought in his mind - gold coins!

Since the mining farm was not built, the miners were quite inefficient, with an average miner mining 1 unit of energy ore every two hours.

But even so, when evening came, 22 miners mined a total of 54 units of energy ore, bringing Meng Chen a profit of 54 gold coins.

Meng Chen's face was full of joy, and he muttered to himself: "Without a mining farm, a miner working 10 hours a day can bring in 5 gold coins. Once the mine is built, the efficiency of mining energy ore will be doubled. When the mine is full, it can bring in 500 gold coins per day. This cave...... It's a mountain of gold! ”

At this time, it was getting late, and Meng Chen returned to the City of Hope with the miners and the exploration team.

The emergence of energy ore greatly relieved Meng Chen's economic pressure.

The income of 500 gold coins per day allowed Meng Chen to let go of his hands and feet and vigorously build the City of Hope for a period of time in the future.

Even if there is a temporary lack of metal resources, Meng Chen, who is "not bad for money", can also buy it through the trading market.

The most important thing for Meng Chen at the moment is to train enough miners to fully mine the energy ore of this mine.

Back at the city hall, Meng Chen lay on the bench in a comfortable mood, and said secretly in his heart: "Although the problem of metal resources has not been solved for the time being, more valuable energy ores have been accidentally discovered. It seems that it is time to build the Altar of the Immortal and the walls, but ...... The city wall is a super money-making commodity! ”

To build an Altar of the Immortal, you need 600 gold, 200 units of wood (white), 200 units of stone (white), and 20 units of metal (white).

White quality wood can be found within the urban limits;

White quality stone, Meng Chen has found a mining site;

White quality metal, Meng Chen can only buy through the trading market, and it costs about 240 gold coins;

As for the last 600 gold coins, it was not difficult for Meng Chen, who had energy ores, at all.

According to this estimate, the investment of an altar of the Immortal should not exceed 1,000 gold coins.

As long as the mine is fully engaged in energy ore, it only takes two days to earn 1000 gold.

The cost of the Altar of the Immortal is not expensive, and the cost of the city walls is ...... Meng Chen did the math at the beginning, it was an astronomical amount!

According to Meng Chen's plan, the City of Hope needed to build two walls, the inner and the outside.

The inner walls are 400 meters long, 20 meters high, and 6 meters wide, and their main role is to protect the city's core buildings, such as the town hall, the academy, the altar of the Immortals, the library, and so on.

The outer walls were built along the edge of the city, with a side length of 20 meters, a height of 20 meters, and a width of 6 meters, and were mainly used to protect production and secondary buildings, such as plantations, lumber yards, warehouses, dwellings, etc.

The construction of the outer walls was a long-term project, and for the time being, only the construction of the inner walls will be discussed.

Through the light curtain, Meng Chen learned that the construction of this 1,600-meter-long inner city wall would cost 32,000 gold coins and 96,000 units of stone (gray).

32,000 gold coins, which need to be mined continuously for 64 days at full capacity to be saved.

As for the 96,000 units of stone......

When a quarry is full, it can mine 150 units of stone (gray) per day.

If you want to collect 96,000 units of stone (gray) in 64 days, you need 10 full quarries.

Combined with the same number of coachmen, only the two professions of miner and coachman would need to occupy the summoning share of 1,000 civilians.

"Now, I finally know why the Qin Dynasty died II! Just an inner city wall needs to consume so much people's power. How could the Qin Dynasty, which built the Great Wall, last for hundreds of years? Meng Chen lamented.

However, the walls of the City of Hope had to be built after all, otherwise, when the evil moon was in the sky, how could Meng Chen resist the terrifying beasts?

The outer walls may not be built before the end of the year, but the inner walls must be built before winter comes!
