Beside me, Xiaodie and Xiaokong have woken up and are getting dressed. Xiaojin ran out every three hours last night to set up the burning pit. They are still sleeping now, so don't disturb her!
After having breakfast in the morning, Luo Yu took a look at the situation of the thermal energy storage box. It reached the level of 18000/50000 overnight, which was not bad. It would be full in a few days.
Early in the morning, Luo Yu directly cut all the stones dug by the diggers and badgers last night. Adding in the inventory from yesterday, there are now 10W of stone bricks, so he can consider starting.
plan!
Strike array!
Yes, the previous battle with the Fiery Twin Stars gave Luo Yu inspiration. He wanted to build a strike array to completely eliminate the invading enemies from the east at the entrance!
The design of the strike array is complex, but Luo Yu already has a detailed blueprint in mind.
He walked to the edge of the territory to the east. Looking at the fog and the looming air wall in front of him, Luo Yu determined his position.
Every attack comes from this location!
All attacking units or neutral units walked in from the area in front of them, and Luo Yu basically calculated that the intersection hidden in the fog should be about five meters wide.
The construction of the strike array starts from here.
First, Luo Yu needs to build a corridor so that the attacking units must enter the strike formation along the corridor he has built.
As for the two walls that make up this corridor, Luo Yu chose to make mechanical walls.
This is an advanced wall that appears after unlocking the city wall technology. Its hardness depends on the material. The reason why it is called a mechanism wall is that it can hide terrible things such as automatic traps in the wall.
Just like strict fireproof floor tiles can bury thorns underground, so can institutional walls!
This is the wall that Luo Yu fell in love with at first sight.
Each section of the mechanism wall is 5 meters high, 1 meter long, and half a meter wide, so the cost is very expensive, and even gold is used.
Luo Yu started building the first section of the wall close to the air wall. The distance between the two mechanical walls was 6 meters and began to extend.
The spacing is 6 meters and is close to the air wall, which ensures that all units entering will be within the wall at the first time.
The two walls extended for a short time. After five meters, they immediately turned at a right angle and began to extend to the left.
The reason why he made a sudden turn instead of leading straight to the position was because Luo Yu wanted the opponent to stay in the corridor as long as possible, so that the agencies on both sides could kill more enemies.
At the same time, turning can also make more reasonable use of space. There is only one principle. The longer the enemy stays in your strike formation, the higher their mortality rate will be.
The corridor extended to the left for 60 meters, and suddenly turned a corner and extended to the right. This time, it extended to the right for a distance of 120 meters.
If the entrance is the center point, then turn 60 meters to the left and then 120 meters to the right to balance the left and right. In this way, the total length of the strike array will be 126 meters, which will look better.
Why the number 126?
Because Luo Yu will build arrow towers and automatic crossbows on both sides of the corridor, both on the left and right sides. The number 120 meters is the coverage area of the arrow towers and automatic crossbows. When the enemy enters the corridor, no matter which end it is at, it will bear the rain of arrows from both sides.
Attacks are difficult to defend against.
There is a corridor that extends straight from the entrance, then turns left for 60 meters, and then to the right for 120 meters. The first quarter's strike formation corridor is laid out.
Total cost: 25200 stone bricks, 2520 iron ore, 2520 silver, 126 gold.
Everything else is fine, but the consumption of stone bricks is really high.
Luo Yu planned to build three sections of such a serpentine corridor. After having the template for the first section, the next two sections were easily constructed and were quickly completed.
The total cost is 76,000 stone bricks, 7,600 iron ore, 7,600 silver, and 380 gold.
The first ring of the strike formation that Luo Yu envisioned was built.
The second ring is naturally to prevent attackers or other units from climbing over the wall from above.
Luo Yu spent iron ore to buy a large number of iron spikes and installed them on the top of the mechanism wall.
These iron thorns are so densely packed that there is no room for handholding or footing. If you really have the courage to climb over one of them, you will definitely be disabled.
Only those who can fly, or those who are extremely agile and can jump five or six meters high can jump out.
If he really had that method, it would have to be Luo Yu himself.
Building the iron thorns consumes a lot of iron ore in Luo Yu, but he has saved a lot of iron ore these days, which is enough.
The third step is the arrow tower.
There must be an arrow tower at each corner. There are 6 corners in total, which means 6 towers are needed.
[Auto-attack arrow tower (3000 pieces): wood*30000, iron ore*5000, silver*2500]
Building six arrow towers requires 18W of wood and 3W of iron ore. There is indeed still iron ore stock, but Luo Yu is not willing to use up all the stock. Anyway, the price of iron ore on the market does not fluctuate much now. Just buy it all.
Already.
The current price of 18W wood is 1:2.5, which is 45W.
3W iron ore and 6W silver can be purchased, plus the 15,000 silver consumed by the six arrow towers, the total is 52.5W silver.
There are currently 252.6W silver in the base, and the cost is a fraction.
If you have money, you can really do whatever you want.
Clicking on the auction house to buy, buy, buy, before a burst of buying, all kinds of materials were piled up in front of him. Luo Yu directly clicked on building, but in a moment, six arrow towers stood outside the wall.
The shooting range of the six arrow towers almost covered the entire corridor, but Luo Yu knew that this was not a trump card.
After all, the enemy enters the corridor, and there are walls on both sides of the corridor. The arrow rain can have a half hit rate, which is considered good.
Luo Yu's real trump card is to build a fire-intensive strike formation at the exit of the corridor!
It is also the real core of this formation!
This will require the use of the 38 automatic crossbows built previously.
Previously, Luo Yu spent a lot of money to build 38 automatic crossbows in order to defend the south, and traded 4 of them with others. There are still 34 left, which can all be placed on the fire array.
Place it on both sides. If an enemy comes out of the corridor, he will be shot by 34 crossbows, which will probably kill him on the spot.
The corridor is only so wide, and not many people can rush out at once, which means everyone will die if they come out.
However, it also needs to be particular about how it is arranged.
Luo Yu started building a fence again, this time it was not a mechanical fence, but a much cheaper high-end fence.
