After Luo Fei's star promotion, more Conscripts started to undergo Star Promotion in succession.
Whether it was Wang Hu and Li Biao or those new recruits, they were not far from promotion; as the battle went on, people began successfully promoting one after another.
Meanwhile, the number of zombies below had dropped to only half, it seemed this defensive war was going to succeed.
But crises tend to appear at such moments.
Several Mutated Zombies rushed to the door; Luo Fei and Xu Haoran each took down one, but the largest giant zombie and two other quasi-giant zombies still charged to the front of the minibus.
Luo Fei and two Conscripts simultaneously opened fire on the giant zombie, bullets clinking off its body, though some blood appeared, it wasn't causing lethal damage.
Even bullets from the semi-automatic rifle hitting its forehead couldn't penetrate its brain!
"This is an Armored Zombie!"
Ye Fan named it so, as the layer of cuticle on this thing was tougher than iron plates.
The Armored Zombie attracted the gunfire, and the zombies behind swarmed up, crowding to the front of the restaurant.
The Armored Zombie, with no retreat, began to wave its large claws, pushing against the minibus.
The powerful claws penetrated directly through the body of the minibus, as if to tear it apart from the middle.
"Not good! We can't let them destroy the minibus, if it doesn't block the door, they could charge upstairs."
Xu Haoran immediately pulled a grenade from his waist, pulled the pin, and threw it down.
A fireball exploded in the zombie horde.
The Armored Zombie located at the central point of the grenade was knocked down by the blast wave.
Broken glass flew in all directions, Ye Fan ducked hurriedly to avoid it.
Once the smoke cleared, there were quite a few zombie corpses, dismembered limbs around.
Yet, the Armored Zombie at the heart of the explosion shakily got back up.
Though it had many injured areas, such damage was ineffective against zombies; as long as its brain wasn't penetrated, it could crawl on half a body.
"Sir, grenades are not particularly effective against zombies, the Armored Zombie's defense is too high; without large-caliber sniper weapons, it's tough to kill it."
Ye Fan nodded, feeling somewhat anxious.
"Is there no way to kill this thing?"
"There is a way, which is to continue using the mining vehicle; using either anti-aircraft guns or armor-piercing incendiary rounds should kill it. However, there are too many abandoned cars here, the precision of anti-aircraft guns isn't guaranteed, and armor-piercing incendiary rounds are too destructive, blasting them might cause surrounding cars to explode, unless we clear the cars a bit."
"Alright, you and Li Biao go drive and clear them, act quickly, we can hold on here."
"Understood!"
Xu Haoran immediately called Li Biao, the two of them jumped out of the window again, onto the mining vehicle, opened the hatch from the protruding part, and got in.
As they went to clear the area, Ye Fan was a bit anxious here.
The initial preparations weren't thorough; they should have cleared the nearby abandoned cars before taking action, but now they were in crisis.
Right now, blocking the Armored Zombie outside the door was imperative.
If the zombies charged upstairs, while they wouldn't face total wipeout, casualties would be inevitable.
"What to do? The minibus can't hold much longer."
Ye Fan suddenly thought of something.
"How could I forget this!"
He quickly opened the Red Alert interface.
The Red Alert page had four options: main buildings, defense buildings, soldier units, and mechanical units.
There was a Wall option under his defense buildings.
In the Red Alert game, walls could block advancements of soldier units, and no matter how many soldiers there were, they couldn't breach the Wall, only tanks could bombard through.
If a Wall was constructed at the door, blocking zombies shouldn't be an issue.
Ye Fan was stunned when he opened the Wall option.
Because there were three types: Wall No.1, Wall No.2, and Wall No.3.
He had only seen one type while playing the game before, somewhat puzzled, he immediately asked Nana: "Nana, what's the difference between these three Walls? Describe quickly."
"Sir, Wall No.1 is 3.5 meters high, half a meter thick, reinforced concrete structure, can be fitted with barbed wire, but soldiers can't ascend for sniping; costs 20 Gold per meter, with barbed wire adds 5 Gold per meter."
"Wall No.2 is five meters high, 1.5 meters wide, soldiers can ascend for sniping; costs 100 Gold per meter."
"Wall No.3 is ten meters high, four meters wide with embrasures, soldiers can ascend for sniping; costs 500 Gold per meter."
No further explanation was needed; Ye Fan understood, the Wall options were also upgraded with the system.
The three Walls should suit different situations, especially Wall No.3, ten meters high, three meters wide, entirely reinforced concrete, not just zombies, but tanks couldn't break through.
Such a Wall would be the greatest guarantee of life for survivors if a base was established.
Of course, Ye Fan didn't need Wall No.2 or Wall No.3 right now; Wall No.1 sufficed.
No matter how aggressive the Armored Zombie seemed, a 3.5-meter-high, half-meter-thick Wall was unbreachable for it.
Ye Fan glanced at the restaurant's ground floor door, nearly two meters wide.
"Produce a two-meter Wall immediately."
"Certainly, Sir, do you need the barbed wire attachment? However, without an actual Power Plant, the barbed wire can't be electrified."
"Not needed, the Wall will do."
"Please wait, it will take twenty-five seconds."
Ye Fan said to Luo Fei beside him: "Come with me to cover me, everyone else keep sniping."
He led Luo Fei downstairs, to the front door, seeing the minibus had already been torn open.
The Armored Zombie had squeezed into the minibus, and upon seeing Ye Fan and Luo Fei through the other side of the glass, it seemed to go berserk, roaring from its mouth, smashing the glass with swinging arms.
"Sir, be careful, they're charging in!"
Ye Fan was indeed scared; the Armored Zombie's ferocious face, the surrounding zombie horde's roar, all rattled him; one misstep and he'd become zombie fodder.
But he had to stop the zombie horde's advance, gain time for Xu Haoran's side.
"Open fire! Drive them back a bit for me!"
Luo Fei, a brave warrior, lunged forward, semi-automatic rifle rapid-firing, the drum rotating, shell casings popping out of the gun.
Ratatatata~~~~~!
Such firearms had difficulty killing the Armored Zombie, but could push it back; the Armored Zombie was forced two meters back.
At this moment, the system's Wall was already produced.
Ye Fan gritted his teeth and charged forward, Luo Fei retreated slightly, leaving space at the door for Ye Fan.
Spurred by the prospect of food, the Armored Zombie lunged again, swiftly tearing open the other side of the minibus with its claws, about to rush into the door!
Ye Fan could almost feel the breath from the Armored Zombie's mouth now, with less than half a meter between them!
Despite the imminent threat, he acted swiftly.
Opened the defense page, clicked Wall, placed!
Crash~~~!
A giant Wall over three meters high and two meters long materialized from thin air, stretching from the ground floor to the ceiling, punching a hole in it!
The outside zombie clamor seemed abruptly cut off.
Ye Fan exhaled deeply, even hearing the Armored Zombie's angry howls and pounding on the Wall.
He slumped against the Wall, took off his cap, wiped the cold sweat from his forehead, then dug out his Cordyceps from his pocket.
Tang!
The lighter ignited.
Hiss~~~!
A smoke ring blew out.
So satisfying.
