After following Mu Lao to the side, Mu Lao said to Meng Chen cautiously: "Little Brother Meng, the old man has something to say...... But I don't know whether to talk about it or not? ”

Meng Chen arched his hand and said, "Please also ask Mu Lao to make it clear!" ”

After pondering for a moment, Mu Lao sighed and said, "Little Brother Meng, if you have the opportunity, leave the Earth Dragon Valley as soon as possible!" ”

"Why?" Meng Chen wondered.

Mu Lao said slowly: "The reason why Earth Dragon Valley is called Earth Dragon Valley is because there is a group of terrifying creatures living in Earth Dragon Valley-Earth Dragons. If it was just a few earth dragons, with the strength of the commander, it should be easy to deal with, but there were hundreds of earth dragons in the Earth Dragon Valley. Therefore, the choice of the people of Ocellier to build a village in the Dilong Valley is a very bad decision! ”

Meng Chen was shocked in his heart, and hurriedly asked, "Is the earth dragon that Mu Lao said the kind of monster that wears yellow-green scale armor and looks like a lizard?" ”

Mu Lao was surprised and said, "Little Brother Meng has already seen it?" ”

"Hmm!" Meng Chen nodded with an ugly face, and sighed in his heart: "Hundreds of monitor lizards? The City of Hope is in big trouble! ”

Mu Lao glanced at Meng Chen sympathetically and persuaded: "Dilong Valley is very dangerous, it is better for Little Brother Meng to make plans early!" ”

Meng Chen thanked him: "Thank you Mu Lao for reminding me!" ”

Subsequently, Mu Lao led the villagers to march towards Shanli Village in the northwest direction of Dilong Valley.

The City of Hope had already been built in the Earth Dragon Valley, and it was impossible for Meng Chen to leave easily, even if he knew that the Earth Dragon Valley was very dangerous, Meng Chen could only hold on.

Looking at the backs of Mu Lao and the others gradually moving away, Meng Chen secretly said in his heart: "Since the first batch of people have already broken into the Earth Dragon Valley, there will definitely be more people coming in the future. Today, the inner walls of the City of Hope have not yet been built, and they must find a way to stop the trespassers in the Land Dragon Valley. Moreover, the energy ore that is suspected to be a tribute stone is also an existence that cannot be exposed! ”

After returning to the city hall, Meng Chen immediately summoned the holographic map.

At this time, there are 6,350 units of stone (gray) in the four warehouses of the City of Hope, and the gold coins in the resource space are as high as 12,524.

The inner wall can be built in sections, and the 6,000 units of stone (gray) and 2,000 gold coins needed for the first 100-meter-long inner wall have been collected.

After thinking about it for a while, Meng Chen decided to build this section of the city wall on the south side of the City of Hope.

Then, Meng Chen came to the south of the city hall two hundred meters and gave the order to build the first section of the inner city wall through the light curtain in his mind.

"Gold - 2000, Stone (Gray) - 6000, start building the wall (1st tier)! After 360 hours, the build was complete! ”

The silent appearance of ashlar on one side is freely spliced under the action of an invisible force field.

"A 100-meter-long inner city wall will take half a month to complete. I hope that before the cold winter comes, all the walls within the sixteen sections can be completed! Meng Chen sighed.

Currently, the City of Hope has a total of 160 quarrymen, and 10 newly trained quarryers join every day.

According to Meng Chen's estimates, it would take at least ten days to gather the stones for the inner city wall of the second section.

However, Meng Chen planned to build a parapet wall in the northern mountain pass of Dilong Valley before building the second section of the inner city wall, so the construction time of the inner city wall in the second section may have to be postponed for a few days.

The width of the northern mountain pass of Dilong Valley was about two hundred meters, and Meng Chen planned to build a parapet wall two hundred meters long, ten meters high, and two meters wide to completely seal the northern mountain pass of Dilong Valley.

It was not enough to have a parapet, two guard towers and a fortress for the soldiers had to be built.

Note: Soldiers in the City of Hope must have a fort or marching tent if they want to be stationed outside the city. Otherwise, you can only return to the City of Hope residence before nightfall. Forcing soldiers to spend the night in the field can cause a significant drop in loyalty, and in severe cases, even lead to rebellion.

Through the light curtain, Meng Chen learned that this parapet wall needed 1,000 units of stone (gray) and 300 gold coins, and two guard towers and a fortress required a total of 400 units of stone (gray), 400 units of wood (gray), 40 units of metal (gray) and 400 gold coins.

In the evening of the second day after Mu Lao left, Meng Chen had already saved up enough stone to build the parapet.

Due to the location of the parapet wall, which was already beyond the urban area of the City of Hope, Meng Chen could only consume 100 gold coins to collect the 1,000 units of stone into the resource space.

Taking advantage of the fact that it was still dark, Meng Chen immediately rushed to the northern mountain pass of Dilong Valley and gave the order to build a parapet wall.

"Gold -300, Stone (Gray) -1000, start building a parapet (tier 1)!" After 72 hours, the construction was complete! ”

In the following five days, Meng Chen successively built two guard towers and a fortress.

The guard tower is a tower-shaped building with a diameter of six meters and a height of more than 20 meters.

At the lookout at the top of the guard tower, five shooters can be stationed to block and strike at an area of three or four hundred meters.

As for the garrison fortress, it is a stone building with a diameter of more than 20 meters and a height of 7 or 8 meters, and the fortress can accommodate up to 50 soldiers.

Meng Chen sent a guard team of 20 swordsmen and 10 elite archers to garrison the parapets, guard towers, and fortresses in the northern mountain passes of the Dragon Valley.

After completely sealing off the mountain pass in the northern part of Dilong Valley, Meng Chen muttered to himself: "The terrain of this mountain pass is dangerous, but it can be built into a pass for foreign exchanges and trade. ”

When Meng Chen returned to the town hall, he found that Alfred had been waiting for a long time.

"Alfred, what's the matter?" Meng Chen asked.

Alfred replied respectfully: "My lord, during this time, the earth dragons have frequently tried to invade the north, although they have been driven away by their subordinates and soldiers, but they have been too passive to defend. ”

When Meng Chen heard this, he said with a solemn expression: "How many invading earth dragons are there?" ”

Alfred said in a deep voice: "A few days ago, it was only about two or three, but today there are five heads!" ”

"Five-headed? Mu Lao said that there are hundreds of earth dragons in the Earth Dragon Valley, and it seems that the earth dragon group has not been dispatched on a large scale! Meng Chen muttered to himself.

Afterwards, Meng Chen asked, "Alfred, if you attack with all your might, how many earth dragons can you deal with at one time?" ”

Alfred replied, "Three heads at most!" ”

"What if you add 60 elite archers and 40 elite swordsmen?" Meng Chen continued to ask.

Note: After this period of hunting, there are some swordsmen and archers who have reached full experience and have been trained to become elite swordsmen and marksmen.

Meng Chen didn't mention ordinary swordsmen and archers, because against the powerful earth dragons, the attacks of ordinary swordsmen and archers would not break the defense.

Alfred thought for a moment and replied, "Ten at most, and it will cause a lot of casualties!" ”

Meng Chen asked again, "What if you add twenty three-bow bed crossbows?" ”

After a moment of silence, Alfred replied, "Thirty heads at most!" ”

Meng Chen nodded, and said secretly in his heart: "It seems that the main attack must be carried out to weaken the strength of the Earth Dragon Group, otherwise the local Dragon Group's temptation is over, and when it invades the north in a big way, the City of Hope will definitely not be able to withstand it!" ”
