At 12 o'clock in the evening, after Chen Long fell asleep, Lu Wei came to the tower defense base.

"Wei, you're back." Kay said happily.

"Well, how many energy cores are there in the base now?"

"78 in total."

"Oh, so much." Lu Wei hurriedly opened the resource center and checked the resources inside.

――――

Seeing the [Remote Artillery Tower] in the countdown state of R&D, Lu Wei was immediately overjoyed.

In "Defense Formation", the long-range turret has the first range, the attack power is close to the first, and it is a super defense tower with a wide area of destruction, which is the ultimate killer against large-scale monster invasion!

Of course, not everything in the world is the most perfect, if it weren't for the low rate of fire that limited the power of the long-range artillery tower, with this kind of defense tower alone, Lu Wei would have the confidence to deal with the challenge of any monster.

Even so, Lu Wei still has reason to be happy, and there will be another tower defense weapon in his hands.

"Wei, you came late today, and now there are about 800 monsters gathered outside the base, and there are several new monsters that are very threatening, and you must deal with these threats in time."

"I know, I'll adjust the tower formation right away."

Lu Wei began to adjust the tower formation on the defensive platform.

Seeing that there were still 3 machine gun towers in the middle of the 10-type road section that were displayed in the most basic green, Lu Wei upgraded all the three green machine gun towers to yellow.

"There are a lot of monsters outside the base today, and there are three or four monsters that can be invisible, and one laser tower is obviously not enough...... Build two more! ”

Lu Wei built a second-level laser tower at each of the two T-shaped corners in the middle of the defense platform.

The second-level laser tower can be built directly, and there is no need to build the first-level laser tower first and then upgrade to the second-level, eliminating the intermediate links.

The advantage of directly building a second-level defense tower is that it saves about 20% of the resource consumption, and only needs 320 normal resources and 60 special resources to build a second-level laser tower.

"The control tower must be built, otherwise so many invisible monsters, if there is a little omission, there is a risk of losing the energy core."

Consuming 300 ordinary resources and 30 special resources, Lu Wei built another control tower in a ten-type road section in the middle of the platform.

After some operation, only 89 points of special resources of 269 points remain.

"There are a lot of monsters outside, and I'm afraid that such a small number of defense towers will not be enough, so for the sake of safety, let's build 4 more cannon turrets!"

After consuming 800 normal resources and 80 special resources, Lu Wei built 4 more cannon turrets.

"We've built seven towers, which is almost enough...... Kai, open the vents and the base gates, and let the monsters in. ”

"Understood!"

Beep - The alarm sounds, and a large number of monsters enter the base.

First of all, there are flying monsters, there are nearly a hundred, in addition to the runners, today there is another kind of flying monster called [octopus], the octopus has a high defensive power, and the cannon turret may not be able to kill it with one shot, and it takes two or three cannons to kill it.

Of course, the number of flying monsters was small, and under the combined blow of the cannon turret and the machine gun tower, it was quickly eliminated.

Kick and kick, a lot of Sisuo's footsteps sounded at the entrance of the passage, and the land monster entered.

Boom, boom, the Flame Tower spewed out high-temperature flames, burning a large number of low-level monsters with a high temperature of 1800 degrees.

Suddenly, the machine gun tower was powerful, and the dense rain of bullets was like a network of intertwined fire, and the monsters screamed and screamed.

Boom, boom, the most powerful is the cannon turret, one cannon takes one, the eight cannon turrets are all in unison, and the loud rumble overwhelms all the other towers or monsters.

A yellow laser struck a fast-running monster with a yellow laser, burning it through in less than two seconds.

All kinds of defense towers have been powerful, but the number of monsters entering the base in this wave is indeed a bit large, especially the invisible monsters that are transparent, the number is surprisingly large.

Fortunately, the control tower can manifest invisible monsters within a radius of 100 meters, guiding other defense towers that can't find invisible monsters to attack...... From this point of view, although the control tower has no attack power, it is much more useful than an attack tower.

"Wei, pay attention, there are two snails that have entered the base, they are very threatening, I am not absolutely sure to destroy them!"

"Snails?"

[Snail: The snail is a type of intruder that has a protective shield and can protect nearby friendly forces, and the protective shield fired by the snail can resist the destruction of the incoming attack, and it is also powerful against thermal attacks. Machine gun towers or cannon turrets reduce the protection of the shared shield, and the snail can carry three energy cores.

"The snail's protective shield is very thick, which can resist high-intensity attacks and last for a long time, and the armor on its body is also very thick, even if it loses the protection of the protective shield, it can last for a long time."

Not only that, Lu Wei saw that the protective shield released by the snail was very large, and there were seven or eight small monsters following it inside, if the protective shield was not broken, and the snail arrived at the energy center with these little monsters, I am afraid that it would take away a lot of energy cores.

Lu Wei's eyes froze, staring at the two snails and said, "Kai, concentrate your firepower and attack the snails with all your might!" ”

"Boom!"

"Boom!"

The cannon's cannons hit the snail's shield hard, some of the shells were bounced off by a hemispherical imitation shield with a smooth arc, and some of the shells squeezed out a depression after hitting the shield, but the surface of the shield with the characteristics of dispersing attack appeared a circle of wavy wrinkles, and disappeared in the blink of an eye.

"Keep banging, you must break through that protective shield!"

Boom!

Bump Bump Bump!

The machine gun turret and the cannon turret are powerful at the same time.

The speed of the snail is not very fast, the more you go to the middle of the platform, the more blows you take, and when you come to a ten-type intersection, the six secondary machine gun towers fire at the same time, and the surface of the protective shield of the snail walking in front is covered with waves like fish scales, which become more and more violent, and finally it can't hold on, the protective shield cracks with a bang, and the bullet pours on the snail's body.

The machine gun tower didn't do much damage to the snail, but after the snail came to the vicinity of a laser tower, the laser hit the snail's body, and in less than two seconds, it let out a scream and quickened its pace, but after running out of the attack range of the laser tower, it had already withstood nearly 6 seconds of laser irradiation, and a terrifying hole appeared in its back, not to mention, and a raging fire burned all over its body.

So, after not taking two steps, the snail fell to the ground and burned into a pile of debris.

"Laser tower, awesome!"

Lu Wei excitedly gave a thumbs up to the laser tower and praised it.

However, Lu Wei was not happy again, and the remaining snail was very cunning, not to mention that he was not attacked by the death snail, and he always walked against the wall of the defense platform, avoiding the attacks of many shells and bullets, and after arriving at the energy center, he took away the three energy cores.

Not only that, but the five or six little monsters protected in this snail shield also took six or seven energy cores, and then left immediately.

But the snail seemed to be very smart, and instead of leaving immediately, it rested for a while behind the Energy Center, which was the tower's blind spot.

Kai's face changed: "It's not good, that snail is recovering its energy, and when its energy is replenished, I'm afraid I won't be able to destroy it." ”

Ten minutes later.

Several of the mobs that took the energy cores were all killed, but the snails that took the three energy cores still walked to the entrance of the passage intact in the same way, and left the base with a swagger.

The base gate is closed.

Lose three Energy Cores.

Lu Wei's heartache dripping blood engraved the image of the snail deeply in his heart, gritted his teeth and said, "Damn!" You're lucky this time, if you dare to come next time, I'll call you to come back! ”

Kai calmly and calmly allocated three energy cores from the resource warehouse, which were replenished to the energy center through metal pipes, continuing to maintain the full operation of the base.

Seeing Lu Wei's annoyed look, Kai smiled and comforted: "Friend, it is normal for the energy core to be lost, you have done it well enough, take your previous manager, it is very common for him to lose more than half of the energy core at one time, and the loss of all the energy cores has also occurred, compared to him, your performance is already great." ”

"Is that really the case?" Lu Wei asked not quite surely.

"It's true, the monsters that invade the base don't just know to come in and die, the best of them may become 'regulars' of the base in the future, and our task is to keep these regulars from too many to make the base unable to function."

"I see—"

Lu Wei nodded, in the end, he still underestimated the monster's IQ, thinking that the monster was a fool who only knew how to send to death, but now it seems that this is not the case.

But he still said unusually firmly: "Kai, believe me, I don't allow 'regulars' to come and go freely in the base, no matter what kind of monster it is, as long as they dare to come in, there is no chance to go back, they have to leave my life here!" ”

"Hahaha!"

Kaihaha laughed, his eyes full of appreciation, and said, "I like ambitious young people, friend, and I'm sure you'll do that!" Hahaha......"

Seeing that the time was not early, Lu Wei felt a little tired, and after saying goodbye to Kai, he went back to his bedroom to rest.
