On the other side of the Wushui River, a large number of L3s appeared, and this kind of power-type mutant zombies were huge, and the group charge they launched could not be stopped by one or two waves of skills.

Soon these L3s stepped on the corpse bridge and rushed under the city wall, Yan Fei fixed his eyes and looked, I will strangle! Every L3 has an S3 crawling on its back! I saw the L3 collectively grab the S3 on their backs, and then throw them all towards the city wall, it's this trick again, human cannonballs!

"Withdraw all pets and defend the walls!" Yan Fei threw away the cigarette butt in his hand, and with a movement of his mental power, the Nine Palace Sword Formation attacked towards the S3s who fell in front of him.

All the pets were taken back to assist everyone to guard the city wall, all the melee professions finally waited for the opportunity to make a move, without waiting for Yan Fei to order, the soldiers consciously went up, one by one S3 was constantly shot down from the city wall, but then more S3 climbed up along the city wall!

"Bang bang!" The turrets on the city wall began to exert their might, often with a single cannonball, at least a dozen L3s flew away, but there were only 2 turrets, and the number of corpses was too large, and the two turrets were just a drop in the bucket.

"All melee professions are not allowed to fight, quickly shoot down the zombies to the city, all the ranged bombardment for me under the city, give me the potion to drink, don't care about consumption!" Yan Fei faced the sudden attack of L3 and S3, and calmly gave orders one after another.

Soon, the entire city wall was in a hurry from the beginning, and gradually stabilized, and the situation at the north gate was once again under control.

"The other three, what's going on now?" Yan Fei, who was fighting, took the time to ask about the situation of the other three doors again.

"Report! Everything is fine at the east gate. ”

"Simon is all right."

"The south gate says there is no pressure."

Wipe! In this kind of large-scale battle, the situation is normal is very abnormal! What the hell are the corpses doing? Do you only care about attacking the north gate and give up the other three? It's impossible, not to mention the wisdom of Z2, even Z1 can't be so stupid! What's more, this corpse tide is likely to be led by Z3!

Just when Yan Fei was surprised, suddenly in the sky in front of him, there were overwhelming mutant birds, and a large number of snakes, insects, rats and ants appeared behind the corpse group at the same time, and what was even more terrifying was that countless reptiles came out of the Wushui River, and these mutant creatures were surrounded by sea, land and air at the same time!

"Rub! A large number of unidentified creatures have been drilled into the Dongmen River! ”

"There are also a large number of unidentified creatures in the Ximen River Channel!"

"Holy! A large number of mutant beasts rushed down from the South Gate Mountain! ”

Reports of attacks came from the east, west, and south gates at the same time. The time to come is always coming, Yan Fei ordered again: "Give me to defend the city wall, don't let a monster enter the city, everyone will use up all my skills regardless of consumption!" One word, kill! ”

"Kill!" "Kill!" "Kill!" The entire Qinglong City resounded with shouts of killing.

"Captain of the logistics team, turn on all the speakers in the city for me, turn the volume to the maximum, and have a powerful song!" Yan Fei suddenly gave an order to the logistics captain at this time.

So, soon a classic Cantonese song sounded in Qinglong City---- Chen Xiaochun's "Invincible"!

Which is called justice,

Which is invincible,

Right and wrong, but it is difficult to determine,

Which has the right to decide,

Heaven and earth can bear witness,

No matter what the background

……

With the sound of energetic music, everyone's blood was completely stimulated, one after another skills were fatal to the corpses, one after another roars came and went, the bloody rain and bloody wind stained the four walls of Qinglong City, the blood slid down the city wall to the wall, and then flowed into the river along the ground, and the entire Wushui River glowed with a bewitching red light under the sunset......

"Roar, roar, roar!" Just when the entire Qinglong City was fighting bloodily and taking care of itself, L4 and S4 finally appeared!

L4, who was twice as big as L3, was wrapped in a thick iron chain and carried an S4 with eight hands and feet behind him, and they all ran towards the north gate of Qinglong City!

And the entire Qinglong City is entangled with the mutant beasts, especially in the face of the attack in the air, the casualties have begun to appear in the Qinglong City, if you face the attack of L4 and S4 at the same time, the Qinglong City is in danger!

"Four Elephant Array, open!" At the critical moment, Yan Fei had to open the city protection array, only to see a semi-circular light curtain instantly envelop the entire Qinglong City, whether it was the mutant beasts and zombies crawling on the ground, or the mutant birds flying in the sky, they were all blocked out of this light curtain!

At the same time, a light and shadow flew out from each of the four corners of the city wall, a dragon, a tiger, a turtle, and a bird four lights and shadows bombarded the mutated birds shrouded in the light curtain, and in the blink of an eye, the monsters in the light curtain were cleaned up, and then, all the monsters within 10 meters around the city wall would be attacked by these four lights and shadows, and the Qinglong City instantly cheered!

Nima! This formation is too bullish! Although it costs a lot of points to open it once, it is worth the money! Yan Fei finally breathed a sigh of relief, fortunately, Lao Tzu has hole cards!

"Hurry up and regain health and mana!" Since he didn't know how long this city protection array could last, Yan Fei had to ask everyone to hurry up and recover.

"With this big array guarding, we should be safe, right?" Liu Yun asked Yan Fei while wiping the sweat from her forehead.

"The first time I used this city protection array, I don't know how long it can last?" Yan Fei spread his hands, saying that he didn't know how long this big array could last.

"Then we can't sit still!" Liu Yun bit her sexy lip and said.

"Since the monsters outside can't attack us now, why don't we use our ranged skills to attack the monsters outside?" Yan Fei proposed as he manipulated the ghost sword qi to attack an S4 outside the formation.

I saw the flying sword pass through the light curtain and make a ripple, and then the S4 was hit on the head by Yan Fei's ghost sword qi, and a bright red damage value floated from the top of the head, -546!

"You can attack!" Yan Fei's eyes lit up, and he couldn't help shouting: "All the ranged professions give me the skills to clean up all these monsters outside!" ”

Suddenly, the city wall once again emitted colorful light, bombarding towards the corpses outside the formation......

"Bang bang bang!" Countless monsters collided against the light curtain, and the entire city protection array was trembling slightly, and the four holy beast lights and shadows of the city protection array were also busy, the number of enemies was too huge, and the four holy beast lights and shadows naturally could not all be taken care of.

"Ding! The protection value of the four-elephant array has decreased by 5%, and the remaining 95%! ”

At this time, the system's prompt sounded, and Yan Fei was stunned, it seemed that this large array could not withstand long-term consumption.

"Hurry up, the protection value of the big array is decreasing, don't keep it, and strive to destroy the monsters outside before the big array is broken!" Yan Fei had to remind everyone again, lest anyone think that there is a large array to protect the city, so they can output it slowly!

Sure enough, after Yan Fei shouted these words, everyone's output speed suddenly increased a lot, and all kinds of skills once again blasted towards the corpse group and the mutant beast group, and the battle entered a tense state again.

A large number of zombies were killed, groups of mutant beasts were killed, bundles of medicine bottles were drunk by everyone, and one skill after another was cast, a mountain of corpses was piled up under Qinglong City, and a sea of blood was set off in the Wushui River!

The protection value of the four elephant arrays continued to fall, 50%, 40%, 30% ......, and it was about to fall below 20%, everyone's eyes were empty, the corpse tide and beast tide that were frantically attacking Qinglong City just now suddenly and quickly receded, and everyone finally got a chance to take a breath.

"What's the situation?" Yan Fei's eyes widened and he looked towards the other side of the Wushui River.

"It's not like we're scared, is it?" The bald head touched his head and asked suspiciously.

"It shouldn't be like this, that Z3 hasn't shown up yet, there must be some aftermath waiting for us!" Yan Fei concluded.

"And a trick? So how to fight? I said, boss, how long can our city protection array last? Long Jianhua said mournfully.

"The big array only has less than 20% of the protection value, and if there are one or two more waves of attacks, the big array will be broken, and when the time comes, there will be hand-to-hand combat again!" Yan Fei said helplessly.

"I hope Z3 will appear soon, as long as it is destroyed, the corpse tide will naturally collapse." Liu Yun muttered in a low voice.

"Hiss, hiss" and a sharp roar sounded, a large number of mutant beasts appeared on the other side of the river, Yan Fei's eyes jumped, and he always felt that something was wrong, the mutant beasts that appeared this time were no longer overwhelming, but sparse, but all kinds of mutant beasts were larger, unlike ordinary mutant beasts!

At the moment of his heart, the information of this group of mutant beasts appeared in Yan Fei's mind:

Mutant Rat Demon King, level 40, gold-level BOSS; Mutant Centipede Emperor, level 45, gold-level boss; After the mutant spider, the level is 50, and the gold-level boss is gold; Mutant Dog General, Level 50, Gold-level BOSS; Mutant Snake King, Level 50, Gold Boss......

Nima! It's all bosses, all gold-level bosses! Even in the sky, flying bosses such as mutant bat kings and mutant bird queens appeared, and these flying bosses flew straight towards Qinglong City under the leadership of a mutant eagle king!

At the same time, behind these bosses, there are countless ordinary mutant beasts and corpses, obviously, the monsters are launching a general attack!

Looking at the Four Elephant Array, which had a protection value of less than 20%, Yan Fei gritted his teeth and had to play the last hole card of Qinglong City.

"Come out, guardian beast!" Yan Fei shouted, only to see a golden light flash in the entire Qinglong City, and then a huge light and shadow slowly condensed into the sky above the Qinglong City, it was a majestic and mighty bull!

"Moo!" An earth-shattering roar came out of the bull's mouth, and the surrounding monsters were affected by the roar, and their forward steps were in unison, and a bright red damage value floated out of their heads at the same time! The roar of the bull alone injured the monsters within a radius of 500 meters, what a spectacular scene!

It's too late, it's too soon! I saw that the huge body of the bull suddenly flashed to the monster crowd, lowered his head, stretched out two crescent-shaped horns, glared at his hind legs, and then ran desperately! All the monsters that were hit by the bull were all thrown into the air without exception!

The bull ran a big arc from north to south, and the flying dust behind him was rolling, and all the monsters in front of him were knocked away! After a circle, there are almost no standing bosses on the ground! Then the bull raised his head and roared, and his huge body collided directly with the flying boss in the sky......
