The foundation of the Prism Tower also has a radius of 100 meters.

"If it is built, it should be 100 meters high!" Lin Xiao looked at the model of the prism tower in his mind again - it was very technological and futuristic, with the shape of a hexagonal prism and a spherical blue magnetic field in the center, in which was a high-voltage current vortex of one million volts.

"The attack of the prism tower requires the consumption of power raw materials, and according to the fixed reserve at one time, the prism tower can carry out up to three large-scale chain attacks before the power plant is built!" Yin said to Lin Xiao when the construction of the Prism Tower began.

"What?" Lin Xiao's jaw dropped suddenly, "There is still such a thing?" ”

Lin Xiao gasped, "I was wondering if the Prism Tower would be able to recover automatically like the Arrow Tower, but I didn't expect it to be the power saving mode!" ”

Since this is the case, then Lin Xiao can't always rely on the powerful power of the Prism Tower, if Yin's image metaphor is not wrong - then the Prism Tower can launch an attack that can help Lin Xiao completely survive the first disaster.

However, that was when all the enemies were gathered within a radius of several hundred meters centered on the Tower of Light.

Obviously, this assumption is difficult to hold, but it can be guaranteed that Lin Xiao's main city will definitely not be destroyed in the three offensives - it would be a shame for Lin Xiao to be beaten to the house!

The construction of the Prism Tower has only just begun, and the process will last for 25 days.

"It will definitely become the first landmark building in the main city when the time comes!" Lin Xiao was quite excited, "Landmark buildings are an incidental function in the main city, if I build a building beyond the current level at a certain level, or build a building with a high rarity, it will automatically be rewritten as a landmark building. ”

A landmark building has all the original functions of the building, and when used as a landmark, it can also increase the attributes of combat units within a certain range.

The stats of landmark buildings have increased significantly, at least more than doubled!

This increase is terrifying, and it basically doubles the combat power of units within the range of landmark buildings!

"The Remnants of Freedom have a skill called 'Frenzy Building'!" Lin Xiao originally planned to let the second-level free remnants build, but was told that the second-level residents could only use this skill on the second-level buildings.

"That's a lot of restrictions!" Lin Xiao couldn't help but complain, "What it means means that the skill of 'Feverish Construction' can only be used when a first-level building is upgraded to a second-level building!" ”

The Prism Tower is a third-level building, and it is given by an infinite world, and 25 days of construction time is absolutely indispensable.

So instead of wasting twenty-five days of a free remnant, let's waste the time of a first-class resident.

"Now I have 4980 wood and 1430 stone, I definitely need to build a farm, and the construction price of the farm is 10 stone and 50 wood, which is very cheap!" Lin Xiao nodded, thinking that this farm was finally not so pitted, "Now there are fifty first-level residents collecting resources from the Tallinn mine, I can't move, but I can produce new first-level residents to build farms, and of course, arrow towers and even turrets." ”

The Prism Tower can basically ensure the safety within a few hundred meters of the surrounding area, so in this safety zone, Lin Xiao decided to build a farm in the inner periphery, build a barracks on the periphery, and build a row of arrow towers in the outer area to expand the defensive range.

"Farms are cheap, but they're not insignificant!" The reason why Lin Xiao put the farm in the innermost part is because the farm can provide the population of combat units, "According to Yin's description, if there are more combat units when the farm is destroyed, some combat units will die randomly!" ”

Lin Xiao couldn't help but want to scold his mother.

"What kind of broken premise is this?" Lin Xiao was indignant in his heart, "If I spend a lot of resources to produce a bunch of mages, just because the population is overcrowded, and I will kill them all, then I won't be angry to death!" ”

So Lin Xiao decided that he must protect the farm and not let the farm be destroyed.

"Produce a hundred first-class residents!" Lin Xiao now has resources and a stable income, and the production unit has begun to be larger, "Anyway, I need to produce it sooner or later, and it will take 50 hours for all a hundred first-level residents to produce, which is a little more than two days." ”

When you think about it, it doesn't seem to be very fast.

Lin Xiao gave the order again.

"Until twelve o'clock in the evening, Mr. Neng will produce 24 first-level residents, and let all of them go to build first-level farms!" Lin Xiao gave continuous instructions to Yin, so that he didn't need to command them one by one.

Lin Xiao witnessed the construction of the first first-class farm.

"Why is the foundation of this farm so big?" Lin Xiao saw that there was obviously only a dozen square meters of houses, how could there be a super large foundation of nearly 100 meters?

"Because the farm's upgrade mechanic will continue to increase the population as it upgrades, the building footprint will also increase!" Yin Wei Lin Xiao explained, "The first-level farm provides 10 people, but the second-level farm directly provides 100 people, and the tenfold increase in population requires such a large foundation, and it may be upgraded to a skyscraper in the future!" ”

"I see." Lin Xiao nodded, "But this is a bit troublesome, the attack range of the Prism Tower was not large, but now it is directly occupied by the farm." ”

According to Lin Xiao's rough estimate, within a few hundred meters of the Prism Tower, 42 first-class farms can be built, and any more will be beyond the protection range of the Prism Tower.

At that time, it was necessary to build an additional arrow tower to protect the farm.

But is the Prism Tower something that can be used casually?

"I must build a dense circle of arrow towers on the periphery of these 42 first-level farms as a defensive ring!" Lin Xiao opened the map and briefly compared the protection range of the arrow tower, and found that the 19 farms on the periphery must have an arrow tower next to each one to ensure that there are no loopholes in the defense circle.

"Nineteen arrow towers, that's 19,000 pieces of wood." Lin Xiao began to calculate in his heart, "And it takes two days to build, I now earn 3,000 wood a day, and I must add this in the ten-day plan." ”

Stable logistics not only requires a stable income from resources, but also the impregnability of the population of combat units is also a very important link.

"I'm not enough!" Lin Xiao also plans to build a first-class barracks to the outer ring of the arrow tower, and then build a huge ring-shaped barracks - all combat units are trained here, responsible for protecting the farms and residents inside, "There must be more defensive buildings to build outside of the barracks!" ”

"It seems that we must continue to develop new resource points!" Lin Xiao had just solved the wild monsters in the Tallinn Mine and obtained a stable resource point, but now he felt that one was not enough, "There are 27 resource points in my territory, and the Tallinn Mine is among the middle to upper ones, and the only advantage is that there are both woodlands and mines!" ”
