Third, with the expansion of territory, the depth of the strike array has continued to extend, far exceeding the original scale. In the future, this scale will become larger and larger, but its essential effect is still the same.
If the enemy can be blocked, a few death corridors and arrow towers can easily deal with it. Facing the unstoppable ancient creatures and air force, even twenty death corridors and a dozen arrow towers are useless.
Mechanical walls, speed bumps, supporting arrow towers, etc., are more expensive as they are built, but as the intensity of the attack continues to increase, the effect becomes less obvious.
Luo Yu believes that he cannot be limited to the glory of the past strike array, and must constantly change his thinking to achieve better defensive effects.
Times are changing, and so must defense ideas.
Now the city wall has been erected, it is tall and thick, and its defensive effect is N times that of the government wall.
Electric shock towers, light energy cannons and stone bead cannons cover almost the entire map. Once the opponent enters the territory, they will also be hit immediately. From this point of view, the first-mover advantage of the strike array has been lost.
In addition, the walls of the strike array will block some of the stone bead cannon attacks, preventing this powerful firepower from being fully unleashed.
Then there is another point. The exit of the strike array needs to be heavily defended. Is it really wise to let Cyclops and others guard there?
Wouldn't it be better to let them stay on the tall city walls and shoot arrows, throw stones, throw spears and so on?
Based on all factors, Luo Yu believed that the strike formation was no longer appropriate and he needed to devote all his limited resources to the defense of the city wall.
There are so many stone bricks to repair the strike array. It is really better to let the stone bead cannon fire a few more rounds. The effect will definitely not be worse than shooting randomly from the arrow tower.
It was such a happy decision.
Luo Yu said: "Xiao Jin, I plan to dismantle the strike formation and deploy the defense forces on the city wall. What do you think?"
"Has it been demolished?"
Xiao Jin tilted his head and thought for a while, but seemed to be unable to understand, so he shook his head and said: "Master, don't ask me, I can't understand..."
Luo Yu laughed, pinched her little face, and began to rearrange the defense of the territory.
The first is the arrow tower. There are 17 2-star arrow towers in the territory. The arrow towers are buildings and cannot be easily moved, but they can be moved by spending money in the system mall.
And it doesn’t cost much to move it.
The city wall is 1000 meters, and the effective killing range of the 2-star arrow tower is actually a radius of more than 200 meters. In other words, the real effective coverage of an arrow tower is about 400. ωωw..net
The arrow tower is 5 meters higher than the city wall, which does not affect shooting. Putting three arrow towers on one city wall can cover the enemies outside the city wall in all directions.
Luo Yu placed three 2-star arrow towers on the south, north and west sides.
As for the remaining eight 2-star arrow towers, they were all placed on the front, that is, on the east side, to ensure frontal fire suppression.
As a result, the era of sparsely firing arrows at the beginning of the attack was over, and the arrow tower was officially changed from the first defense facility to a 200-meter close-range defense building.
After all the arrow towers were transferred, Luo Yu moved the fog of war boxes to the city. Under the two boxes, the fog completely enveloped the city.
Next is the automatic crossbow.
Luo Yu has a total of 45 automatic crossbows. These automatic crossbows have a very short range and low power, but they do not take up much space.
All 45 crossbows were installed on the city wall to enhance the firepower within a hundred meters. This thing is still somewhat effective when used as a miscellaneous soldier.
As a result, all the defensive facilities in the entire strike array were transferred, and Luo Yu simply chose to dismantle the agency walls.
It took half a day to dismantle it section by section, and the entire strike formation was completely dismantled.
More than 2 million stone bricks and 1 million silver were dismantled. The dismantling would destroy a large part of the raw materials, which shows how much Luo Yu had invested before.
The more than two million stone bricks can be said to be a timely rain. Throughout the city, the defensive floor tiles in the core area of the inner city have been laid. The outer city is still land, and a large number of stone bricks are needed to lay the defensive floor tiles. It is not a loss.
.
Luo Yu put the catapult on the city wall again, placing it high and throwing it far. Now the two-shot catapult can provide a good range output.
Even with so many things placed, the city wall is still very wide and does not feel crowded. Luo Yu himself wishes that the entire city wall was filled with various defensive equipment, without even a place to walk...
In this way, the defense equipment was relocated.
With a city, it is natural to have a moat. The previous one was filled in because it was too close, and now another one needs to be dug out.
Now there are many tools and tool animals that can be mined in the territory, and it doesn't take much time to dig a wide moat.
At the same time, Luo Yu is also deeply aware of the importance of the water element. When the time comes, he can let the giant octopus hide in the moat and spray water, and cooperate with the electric shock tower to form a large-scale electromagnetic grid, which will have outstanding effects.
At this moment, the huge building complex to the east disappeared, leaving a piece of white land.
Luo Yu looked at the empty grassland in front of him, with a faint smile on his lips.
Of course, the defense at the east entrance would not just give up. On the contrary, Luo Yu came up with a good idea.
He plans to lay a trap area at the east entrance, paving it with a mixture of mechanical floor tiles and speed bumps, slowing down part of the road, and installing ground spikes on another part of the road. The two-pronged approach will have a miraculous effect.
And the ancient giant wouldn’t hit the ground, right?
If it really wants to be smashed, let it be smashed. Anyway, it is just a thin layer of floor tiles, so let it be smashed.
Waste time and die faster.
Thinking of this, Luo Yu started work directly!
After a while, a trap square of about 2,000 square meters was built, with 1,000 square meters of speed bumps and 1,000 square meters of mechanism floor tiles interlaced in it. An iron spike was buried in every square meter of mechanism ground tiles.
At the same time, the shapes and colors of the speed bumps and the office floor tiles are almost identical, and you can't tell them apart without opening your eyes.
It is worth mentioning that in the past, silver thorns were used to catch people alive. Now that silver has so many uses, it is better to just use iron thorns, which are twice as thick as silver thorns.
For things like tetanus, because there are hospitals, the chance of infection is greatly reduced, so there is no need to worry so much.
Luo Yu walked back to the city wall, looked at the trap square to the east, and nodded with satisfaction.
He looked at the anti-aircraft guns again. Without the strike array, the anti-aircraft guns seemed a little lonely. Luo Yu moved them all back, and eight anti-aircraft guns were placed on the roof of the small attic of the city wall.
These anti-aircraft guns with a range of 2 kilometers are still somewhat useful, and they have a good effect on heatstroke.
At this moment, all defense facilities are completed.
