Lin Xiao had just destroyed the portal here, and a large area of barren land had already been cleared, but zombies had gathered in the distance.

It is no longer a dense and huge zombie team, but a scattered variety of soldier-level and commander-level units mixed together, forming an ultra-long offensive line that stretches for thousands of miles.

Lin Xiao didn't show a surprised expression, as if he had known that this would be the case.

"The whole army retreats!" Lin Xiao gave a direct order, and then flew directly to the main city on a griffin.

The teams on the ground also retreated in an orderly manner, and no one cared about the zombie legions in the distance.

"This extraordinarily long front will last at least ten days!" Lin Xiao understood why this was very clear, "Only this place in the northeast has a large plain, without any obstacles, not even a small obvious mound......"

"That means it's very likely that it's full of enemies." Lin Xiao had long expected such a situation, "That's why I built three ring arrow towers on the northeast side of the barracks, and there are even extremely expensive turrets hidden in them." ”

The turret here refers to the secondary turret.

And the turret has already cost 5,000 stones, and if it is to be upgraded to the second level, it will be directly doubled to 5W stones, Lin Xiao's current income is a luxury consumption unless he does not produce units every day!

"So the number of turrets is very small, and the power of the first-level turret is good, but it is a bit overkill." Lin Xiao thinks that there is no need to use turrets to deal with a large number of ordinary zombies and some other soldier-level units, "Because the power of the arrow tower is enough, plus the consumption of the arrow tower is very small, and the upgraded resources can also keep up, which greatly improves the ability of the arrow tower, and it is completely enough to deal with these soldiers!" ”

Lin Xiao was glad that he had chosen to build a large number of arrow towers instead of a small number of turrets.

"You don't need turrets to deal with crowd tactics, and the lethality of arrow towers is enough." Lin Xiao thought, "But the status of the first-level turret is very embarrassing. ”

The Tier 1 turret can easily kill Tier 1 units, but it does not deal effective damage to Tier 2 units, while Arrow Towers can also kill Tier 1 units.

This creates a phenomenon.

It would be a waste of resources to build a turret without upgrading it to level 2, because most enemies only need arrow towers to deal with, and in the face of thick-skinned enemies like Silver Armor and Abomination, the damage of the first-level turret is still a little worse.

Therefore, Lin Xiao adopted the elite turret plan, so that all the turrets were upgraded to the second level, and hid in the arrow tower group as a killer weapon to kill the opponent by surprise.

It was precisely because of the protection of this layer of defense that Lin Xiao was quite confident.

"Everyone retreat, let them come, come as many as you want!"

The enemy's battle line is long, but sooner or later it will gather on this plain - and then become a living target for the group of arrows.

"Three hundred arrow towers!" Lin Xiao looked at the dense group of arrow towers under him, and there were sharp arrows glittering under the burning sky on every inch of land—this was a fortification that Lin Xiao had invested a lot of resources and time to build.

"Three hundred arrow towers, or second-level arrow towers!" Lin Xiao looked at those pitch-black and shiny arrows, "Each second-level arrow tower can send out eight arrows in the same direction at the same time, each of which has an extremely strong piercing ability, basically able to penetrate more than a dozen zombies or skeletons from before, and even the abomination may be killed with a few arrows!" ”

Three hundred is two thousand four hundred arrows per second.

Converted into the number of zombie deaths, then at least 20,000 zombies will die directly every second before they get close to the range of the arrow tower.

Thinking about it like this, Lin Xiao was instantly extremely optimistic.

"The number of zombies that can accommodate a row at this entrance is just over 10,000......," Lin Xiao made a simple gesture and estimated a number of data visually, "And the attack range of the second-level arrow tower is two thousand meters." ”

It will deal full damage within two kilometers, and at a distance of no matter how far away, the crosshair will be unstable and the arrows will fly.

"But I don't need to think about this, as long as I aim in a general direction, I will definitely hit the zombies."

So what needs to be considered now is whether the safety of the arrow tower itself can be guaranteed.

"At a distance of two thousand meters, who can break through the dense arrow array and destroy my arrow tower?" Lin Xiao thought about it carefully, and it really reminded him of a monster, "That silver monster, silver armor corpse!" ”

"Before, the silver armor corpse once crossed a distance of kilometers and directly killed my second-level mage No. 1, and this process only took a second or two." Lin Xiao was extremely impressed by the silver armor corpse, whether it was hurting Griffin No. 1 before or directly killing the second-level mage No. 1 in seconds later.

"This silver-armored corpse is definitely the most powerful commander-level zombie."

Regardless of its role in the battlefield, the Silver Armor Corpse is definitely the number one in terms of strength alone.

Lin Xiao didn't dare to guarantee that without the cooperation of the priest and the harassment of the knight, the griffin would be able to win the battle alone with the silver armored corpse.

As for the mage?

In front of the super assassin of the silver armor corpse, the mage will simply deliver food unless there are layers of protection.

But Lin Xiao still didn't panic.

"Against the Silver Armor Corps, I have a second-level turret!" Lin Xiao saw at a glance the turrets hidden in the group of arrow towers that he had personally commanded, the black long-barreled turrets and the black ammunition the size of basketballs.

"As long as the silver armor corpse dares to appear, the second-level turret will go down with one shot, and the silver armor corpse will not die but also be crippled!"

Although the speed of the Silver Armor Corps is fast enough, the second-level turret has the passive skill of "locking" - not only is it much more powerful than the first-level turret, but the locking skill makes the turret even more powerful.

"I'm looking forward more and more to the imminent outbreak of war!"

Soon the whole battle line was approaching, the army of zombies was approaching, and those monsters who were crying wolves were coming one after another, running at high speed on the vast barren plains.

5,000 meters!

Arrow towers cannot hit enemies at this distance.

4,000 meters!

The towers are ready to be launched!

Three thousand meters!

All the upper echelons of the arrow tower were fired in unison, and in an instant, the entire sky turned into a pitch black patch - all of them were black arrows, which rained down on the center of the zombie army.

The zombies that were advancing by leaps and bounds against the ground were shot horizontally by the arrow towers at the bottom.

A silver-armored corpse suddenly rushed out of the ranks, which was extremely obvious in the battlefield of Nuoda.

"Launch!" Lin Xiao personally commanded the turret, "Lock the silver armor corpse!" ”

"Boom!"

The shells were like rockets, and the direct friction ignited the air on the trajectory, and began to burn violently before it could be fired.

This was the first time Lin Xiao had seen the second-level turret fired.
