Two days later, a flying saucer-shaped aircraft flew into the occupied area, suspended above the nursery rhyme scientific research base, and landed on a vertical take-off and landing ladder, and a heroic-looking young man, carrying a silver-white war knife, walked down the elevator.

He was dressed in a black power suit, with a well-proportioned figure, very handsome, and stood quietly outside the gate waiting.

A moment later, the door of the scientific research base opened, and a nursery rhyme in a white coat walked out expressionlessly.

"Dean!"

When the young man saw the visitor, he bent down slightly, his demeanor respectful, but at the moment of bending over, a deep heat passed in his eyes.

"It has been determined that the Destroyer is in Cloud City, and it has changed to a benign level, so we don't need to cause more trouble." Nursery rhyme said.

"Dean, the destroyer is from that place, and it is related to the life and death of mankind, if you let it go, I'm afraid it's not appropriate, and before I came, the number one ordered that the destroyer must be brought back to Shenjing Base City......" The young man was a little embarrassed.

"Xilongchen, I'll explain there, what you have to do now is to obey." Nursery rhyme said coldly.

"Dean, don't get me wrong, I don't mean anything else."

Xi Longchen, the super powerhouse ranked third on the Huaxia God of War List, would grovel and try his best to defend because of a nursery rhyme.

"Let's go."

The nursery rhyme walked directly past Xi Longchen, as if treating him as air.

"Huh? Her sword is missing? Xi Longchen's eyes narrowed slightly, and the cold light appeared, but after a while, he returned to normal, followed behind the nursery rhyme, stepped on the elevator, and slowly entered the flying saucer.

The flying saucer suspended in mid-air, after receiving some kind of command, suddenly rose into the air and disappeared into the sky.

Zhang Yifeng, who was cautiously shuttling through the occupied area, seemed to be aware of it, raised his head and looked at the sky, revealing a thoughtful expression.

"Mina, scan the distribution of zombies in the vicinity."

"Master, 100 meters to your left, there are sixty zombies, the specific level is unknown, turn the street on the right-hand side, there are a large number of zombies near the traffic light, the number is huge, the abandoned building 50 meters in front of you, there are mutant beasts hidden, the specific number is unknown, the mutant beasts inside seem to have a strong camouflage ability, and the E3 detection system cannot confirm it."

"Are there any zombies with a smaller number, preferably a lone one?" Zhang Yifeng asked in a low voice.

"I'm sorry, within five hundred meters nearby, Mina didn't find a lone zombie, the smallest group of zombies, there are also 30 zombies, the specific level is unknown."

30 zombies, if it is a first-level zombie, Zhang Yifeng is not afraid at all, but if all of them are second-level zombies, Zhang Yifeng can only kneel.

To be on the safe side, don't be brute.

Although he really wanted to be promoted to a third-level evolutionary, this kind of unsafe thing couldn't be nonsense.

"Mina, can you search the current map of Cloud City?"

"I'm sorry, but all the information recorded by Mina has been deleted."

"Can't it be reloaded?" Zhang Yifeng asked unwillingly.

"It's a pity that there is no E3 detected nearby, so information sharing cannot be realized, and the owner's only bound zero E3 has also turned on the shielding function, and Mina can't read the information."

"Damn, this woman really kept a hand." Zhang Yifeng's face was gloomy, he still thought that exchanging food for artificial intelligence was a big profit, but he didn't expect the nursery rhyme to be so scheming, and he had already cleared all the information recorded by artificial intelligence, and now the artificial intelligence Mina, in addition to using the functions attached to e3, can't give Zhang Yifeng information help at all.

"However, Mina has turned on the information entry function, and the roads and streets that the owner passes through will be recorded in E3 synchronously to form a three-dimensional map, and the more places the owner passes, the more detailed the map will be." Mina said crisply.

Zhang Yifeng nodded, the depression in his heart slowly dissipated, I have to say, the function of e3 is too powerful, especially after the installation of artificial intelligence Mina, it is even more terrifying, don't want it, all module functions, don't use Zhang Yifeng to operate at all, just say a word, Mina will do it for him.

"Go ahead and turn on the scan function and tell me the distribution of zombies at any time."

"Yes, master."

On the way back to Yuncheng Base City from the occupied area, Zhang Yifeng avoided many dangers because of Mina's guidance, but Mina is not omnipotent, especially in the face of mysterious and weird mutant beasts, the scanning function will be seriously weakened, such as what thermal imager, sound detector, life detector, etc., have been deceived by the perfect camouflage of mutant beasts.

Once, under the guidance of Mina, he directly broke into the lair of a third-level mutant beast, if it wasn't for the critical moment when he used the annihilation-level laser gun, I'm afraid he would have hung up a long time ago.

The experience along the way can be written in a book, called "My Three Hours in the Ruins of the Last Days", which must be thrilling and exciting to write, detonating the reader's G-spot.

"Cloud City Base City, I'm finally back!"

Stepping out of the occupied area and looking at the city like a giant beast, prostrate on the ground base city, Zhang Yifeng breathed a sigh of relief.

However, coming outside the Cloud City base city does not mean that it is safe, on the periphery of the level, there are battles everywhere, and there are constantly survivors who come and go are bitten by zombies, mutated, and besieged by evolutionaries.

"What happened?"

Zhang Yifeng's face was full of confusion, there were powerful army guards near the level, how could it be so chaotic, however, the zombie didn't give him time to think, and a second-level zombie flew over, but Zhang Yifeng cut off his head with an alloy war knife.

Here, there are no idlers, and all the survivors who pass by will be attacked by zombies and thus drawn into the battle.

Zhang Yifeng held an alloy war knife, and with the blessing of 1200kg of strength, he was like a killing god, killing from the periphery of the level to the front of the level, and the crackling gunshots rang out like fried beans.

This is the people of the army, who are clearing the field.

However, zombies are entangled with survivors, and their clearance operations have been greatly hindered, so you can't even kill survivors, right?

Roar, roar, roar

At this moment, the wild roar, from far and near, the earth was shaking, like ten thousand horses galloping, a black line appeared in the sky, galloping at a very fast speed, this is clearly a black zombie, which is also mixed with mutant beasts.

"Alarm, alarm, corpse tide, beast tide!"

The terrible alarm sounded outside the level, and all the survivors who were fighting with the zombies turned white, and they left the battlefield one after another, rushing towards the level, running faster than the other, and now the crystal nucleus gods and horses are all floating clouds, and it is important to save their lives.

"Damn, it's a tide of corpses and beasts at two ends in three days, and you can't let people live?" A Level 2 Evolver complained loudly.

"Alas, since that rain ten days ago, these zombie mutant beasts seem to have taken a tonic, and their strength is ridiculously strong, and they will take the initiative to attack the base city."

"Do you think the army can stop it?"

"Isn't this, you forgot the beast tide three days ago, hundreds of mutant beasts attacked the city, and they were not repelled by the army's tanks and artillery, and they picked up hundreds of crystal nuclei for the base high-level in vain, and I heard that there are many second-level white crystals."

Listening to the discussion of the survivors in his ears, Zhang Yifeng's face was solemn, his guess came true, and the Cloud City Base City was indeed no longer calm.

Boom, boom, boom

At this time, near the level, 30 tanks suddenly drove out, one by one the shells were shot, the earth shook, and the blazing fire bloomed in the distance, setting off a bloody storm, and where the shells landed, the nearby zombie mutant beasts were instantly torn apart, and the severed limbs and stumps flew sideways, like purgatory.

"This cannon is well shot, another shot." One of the survivors yelled.

Hearing this, the nearby survivors had black lines on their faces, and subconsciously stayed away from him, looking like they didn't know him.

30 tanks, dozens of large-caliber howitzers fired at once, the sky and the earth were shrouded in light, clouds and smoke were billowing, and the place where the zombie mutant beasts gathered, it was impossible to see the situation clearly, but everyone was cheering, because the danger was lifted.

In the face of the heavy killing weapons of human beings, these zombie mutant beasts are obviously unable to break through the defense line of the base city.

Seeing that the army could defeat the corpse tide and beast tide so easily, Zhang Yifeng breathed a sigh of relief and turned around and walked into the base city.

"Master, Mina found an E3 user in the Cloud City Base City, confirm that the number is 4, is it connected to the other party's system?"

"There are also e3 users in Cloud City?" Hearing Mina's voice, Zhang Yifeng was taken aback, and ordered without hesitation: "Turn on the blocking function immediately, and don't let anyone find out about my existence." ”

"Yes, master."

Just behind Mina's shield, at the headquarters of the Inner City Military District, a colonel officer frowned, looking at the E3 holographic projection on his wrist, and the detected device signal suddenly disappeared.

"The user of the E3 numbered 1, is it her? Or Xilongchen? The colonel's officer muttered.

Entering the base city and looking at the familiar scene, Zhang Yifeng showed a relaxed smile, but of course, when he walked into the slum, he was stunned by the scene in front of him.

The dense crowd of survivors, lying on the top of the square, with yellow and thin faces, missing arms and legs, roaring in pain, and their eyes full of despair.

What's going on?

"It's miserable, it's miserable."

"There used to be zombies, but now there are winged birds that can fly, and the walls can't stop them at all, is there still hope for humans?"

"I heard that there are zombie mutant beasts attacking the city outside the level, alas, is the human race really going to perish?"

The low words came into Zhang Yifeng's ears, making his heart shake, a winged bird that can fly, what the hell is this?

"Find Liu Qiang and them first to find out what happened." Zhang Yifeng thought secretly, and then walked towards his home in the wasteland world.

The narrow and crowded alley was still occupied by survivors, but it was not as miserable as the outside, and it was clear that the so-called winged birds did not cause much damage because of the many tall buildings here.

"Yi Feng, are you back?"

At this time, Niu Heng, who came out with Niu Xiaohui, saw Zhang Yifeng and immediately shouted out happily.
