Disasters would occur every thirty days at intervals, and so far Lin Xiao knew that there were already Level 3 Prism Towers that would take 25 days to build.

"I used to have the conversion privileges of ten second-level residents, and now I have used all of them, and I now have ten of the Remnants of Freedom, and they have a skill 'Rapid Construction' that is used every thirty days!" Lin Xiao recalled what happened after he built all the residential units.

"Rapid Construction: I've used it to build five second-tier barracks and five second-tier turrets." Lin Xiao said in a deep voice.

Grade II buildings can be built directly by secondary resident units – this is a well-known thing.

The construction time of the first-class barracks alone reached five days, and the construction time of the second-level barracks was not short, a full ten days. But Lin Xiao didn't have time to wait for another ten days, so he used the skill of rapid construction.

As for the secondary turret, it is not long, but it also takes five days. When Lin Xiao first built the defensive line, in order to achieve better bombing and defense effects, he demolished five arrow towers and quickly built five second-level turrets - because there were only two days left at that time.

"If only I had more opportunities to build quickly." Lin Xiao longed, but soon he suddenly realized something.

"If I'm hungry for the quick-building skills that I've transformed, won't any of these inhabitants be able to level up?"

Lin Xiao was a little scared, afraid of his own impulsiveness.

"If I can keep upgrading the main city, then the construction time of all buildings will be reduced accordingly, and reaching the highest level may be 'fast construction'!" Lin Xiao thought, "In this way, there are still drawbacks to converting residents, if I have the authority to transform them all, then the possibility of upgrading will be cut off, plus the one-time non-repeatable construction of resident units......"

Lin Xiao can imagine that in the future, the level of his main city is very high, and the number of residents is also very large, but the general level is very low, so the efficiency of collecting resources is not high, and there may even be a gap of several levels.

The more Lin Xiao thought about it, the farther he went, and quickly got rid of these messy thoughts.

"My mission now is to cut the back row and destroy the portal, and these things will be thought about when the disaster is over!" The solution that Lin Xiao could come up with temporarily was to get as many experience points as possible in the dungeon world.

On the frontal battlefield, a large piece of the defensive line was broken, and the blood-red demon imp used his flesh to block the muzzles of the arrow tower and turret, and all the attacks became squibs and even exploded into the defensive buildings next to him.

Silver Armor and Abomination followed, dodging the deadly turret attacks, and the two Great Killers were ferocious and frantically destroying the turrets and turrets that had kept them vulnerable for ten days.

The necromancer began chanting incantations again, this time the skeletons and dark skeletons rose from within the defensive line - within the confines of the main city, and as the demonic imps attacked, more hellfire rained down from the sky.

This is the ability of the demon imp, as long as you occupy a place, you can summon a hellfire in this place again, and then generate more demon imps, and this is also one of the important reasons why the demon imps can't kill enough.

Once the Demon Imps are closing in on you, more Demon Imps will appear.

It's a very unsolvable question, and everything shows the strength of the demon race, even if it's just a demon imp with only a drop of blood!

"Everybody, retreat!" Second Cavalry No. 1 was one of Lin Xiao's most trusted subordinates, and he was in charge of directing Operation Decoy.

It is worth mentioning that these combat units actually showed not exactly the same function in the later battles, and after Lin Xiao's observation, the No. 1 player of each combat unit had stronger functions and command than the units produced later.

Mage No. 1 II, Griffin No. 1 II, and Cavalry No. 1 are all good examples.

It's a pity that the second-level mage No. 1 has died, and died in the hands of the silver-armored corpse that was only seen in the northeast frontal battlefield.

But in this kind of dangerous battle, Lin Xiao can only rest assured that the second-level cavalry No. 1 will command, and only he can have an overall view and a trade-off view that can be comparable to Lin Xiao.

The cavalry continued to use the furious dragon sweep to turn into golden dragons and weave through the enemy's camp, and a few unlucky guys touched the hard bones, and the golden dragon head rushed into the rotting body of the enemy and never came out.

Second Cavalry No. 1 saw everything in his eyes, his voice became deeper and lower, and his heart was extremely painful to see these companions who had been born and died with him one by one in the mouths, fangs and claws of the enemy, and his eyes were already bloodshot.

He was the first second-level cavalry to appear, not only the first second-level cavalry, but also the first first-level cavalry, he was one of the earliest combat units to accompany Lin Xiao, and he was also one of the units with the highest intelligence among the cavalry and was deeply appreciated by Lin Xiao.

Only he can understand the grief of death, even if those companions do not know what death is, what fear is, and what grief is.

But it was enough for him to know!

The cavalry unit quickly retreated under the command of No. 1, and after retreating for several miles, a large number of enemy troops had already entered the range of the Prism Tower.

But Second Cavalry No. 1 is obviously not satisfied with this result, he needs more, he needs to be used as a bait again!

"The Prism Tower's attack effect must be maximized!" Number One said to the forty cavalrymen around him, "We need to pull the monsters again, see, they're attacking barracks and farms, but we need to lure them to the inner turret!" ”

The arrow tower is a defensive building, once a defensive building appears, then the hatred of these monsters is simply instantly filled, and when the time comes, there will naturally be countless enemies who throw down the barracks and farms in their hands and rush in to destroy this arrow tower first.

This tower was first built on the periphery of the first circle of farms.

Beyond this level of the farm is the Prism Tower itself.

The Prism Tower itself is also a defensive structure, but a defensive structure can only attract aggro after launching an attack, so Cavalry One can only draw some enemies into the attack range of the Arrow Tower first.

In this way, the monsters behind will follow closely behind and all of them will rush up.

Second Cavalry No. 1 shouted: "Fearless! ”

Immediately, he led forty cavalry to rush back into the enemy formation with a fearless charge, and then the golden light began to kill wildly.

"Don't fight!" Second Cavalry No. 1 quickly commanded this time, because there were enough people around him, "Don't make senseless sacrifices, retreat after that!" ”
