Seeing that the monster was getting closer and closer, Chen Ye smashed it with his fist again.

Their shells were very fragile, and the mugwort standing at the front was directly shattered in the upper half of his body.

In order to save the oil filler of the boxing gloves, Chen Ye did not use the function of deflagration.

So the organs and tissues that fell to the ground suddenly turned into multiple mutants, screaming and rushing over.

At the critical moment, a buzzing circle of light lit up in mid-air, and then slammed down.

Under the weight of the force field, the mutants quickly became a blur of flesh and blood.

Chen Ye didn't have time to say words of thanks, because a mutant with four arms rushed over from a distance.

He folded his arms and used his stiff fist arm guards to block the swift attack.

Then he kicked it sideways and kicked it directly into the city gate.

With a loud bang, only a puddle of meat was left on the wall at the city gate.

Just when the three of them thought they had solved a few mutants.

The bloody corpses on the ground, a puddle of flesh and mud at the city gate, slowly wriggled and gathered and merged into a new mutated monster.

Chen Ye was a little desperate.

The three of them resisted with all their might.

Wielded fists, precise crossbow arrows, buzzing stance apertures......

Even if the mutant can't get close for half a minute, there are more and more enemies in front of him.

Chen Ye took out the military compound crossbow and emptied a magazine again.

He even threw some oily dragon wood to use as an incendiary bomb.

Crimson flames rose in the area in front of the city gates, and half of the street was lit up by the light of the fire.

Although quite a few mutants were burned, nothing changed for the situation.

If you go on like this, it's a dead end!

"Since you can't leave this place for the time being, you can only find a place to hide first, and then make plans."

Chen Ye smashed open the fiery mutant in front of him with a punch and shouted at the two beside him.

The trio fought and retreated, and began to search for hiding places in the streets of the town.

The town ruins don't really cover a large area, and it's hard to find a place to hide.

At this moment, Chen Ye saw the top of an umbrella-shaped minaret in the distance, flashing with bursts of bright light.

He didn't pay much attention to it at first, thinking it was the moonlight reflected by some kind of building material.

But as he ran, he noticed that the light was flickering regularly.

Three short, three long, three short.

Is this an SOS Morse code distress signal?

Chen Ye immediately took two teammates and hid in the corner of a building.

While changing the military composite crossbow magazine, he looked at Lu Ze beside him:

"Lu Ze, you said before that your squad leader was hiding in the tower?"

Lu Ze leaned against the wall and nodded with a sigh: "Yes, that's right, but I can't contact them at all now." ”

"It should be said that those three girls have been cut off from the outside world, and we are now in this predicament!"

Chen Ye glanced at the mutants who hadn't caught up yet, and continued to ask:

"Were their names grey at the time?"

Lu Ze recalled for a moment, and then shook his head: "No." ”

This means that the system determines that they are still alive.

In this apocalyptic world, there shouldn't be more advanced rules than the system, right?

In this case, Chen Ye looked at the building in the distance and made a decision in his heart.

According to the girls' distress messages, they hid in a tower.

The flickering lights at the top of the spire were most likely caused by them.

Chen Ye set some fire dragon wood on fire and threw it onto the not-so-spacious street to interfere with the mutants' footsteps, and then quickly led the people to the flickering spire building.

From a distance, these minaret buildings resemble super-giant oyster mushrooms.

Visually speaking, it is a stout round tower with a diameter of about fifteen meters, and is topped by an umbrella cover that extends outward.

After Chen Ye walked in, he found that these buildings were really some kind of plants, and he could see the silky longitudinal texture on the surface of the wall.

Cut through the wall with the fangs at the tip of the glove, and some crystal liquid will come out of the broken area.

The monsters at the gates, the minarets made of native plants, and the ruins of this strange town are getting more and more interesting!

Accompanied by a scream, a dense number of footsteps came from the street.

Chen Ye didn't linger any longer, and immediately pushed open the heavy door panel and led the team into the spire.

The structure inside the minaret resembles a tower, with layers occurring every three meters.

Each floor was also divided into four rooms equally, but Chen Ye didn't dare to open the door and go in to check.

Because there was a heavy breathing sound from inside, it sounded like a bad guy to deal with.

There is a vertical pipe in the center of the minaret, and a narrow spiral staircase coils around the outer wall of the vertical pipe, leading to the top of the minaret.

The trio cautiously climbed up the stairs, hearing the sound of a group of mutants passing under the tower.

After climbing for some time, the ceiling finally appeared above the standpipe.

At the end of the spiral staircase, there is a cover that allows you to see a little fire through the gap and hear the sound of staccato talking.

Sure enough, there are people!

Chen Ye immediately took out the compound crossbow and nodded to his teammates behind him.

Then he jerked his hand up to open the cover, and quickly turned over to the umbrella-shaped attic at the top of the spire.

The three people in the attic were startled by Chen Ye who suddenly broke in.

Also, Chen Ye is now wearing giant shark scale armor, and he is also covered with a layer of wildebeest fur.

At first glance, it looks like a ferocious and bloodthirsty orc......

The three girls quickly stood up from the floor and took out their weapons in an attacking stance.

At this time, Lu Ze popped out half of his head from under the cover, saw a familiar face not far away, immediately took off the fur covering his head, and exclaimed in surprise:

"Ran?"

The leading girl was a little hesitant at first, but when she saw the boy who climbed up from the spiral ladder, her expression became very surprised.

But she didn't show too much surprise, and instead raised the rusty bronze sword in her hand:

"Are you alive or dead?"

"What a living and dead, I'm Lu Ze!"

Lu Ze was a little aggrieved and wanted to step forward to explain, but was pulled by Chen Ye.

Chen Ye held the compound crossbow and said with a serious expression: "If they are also mutants, you just walk over like this, I'm afraid you will be directly divided." ”

"So what are we going to do?"

Lu Ze finally saw his classmates and looked a little impatient.

Li Ranran was very calm, she looked at the few people in front of her, then looked at Lu Ze, and suddenly asked:

"Given that the function f(x)=ae^x+4x, for any real number x₁,x₂∈(-∞,+∞), and x₁≠x₂, the inequality (f(x₁)-f(x₂))/(x₁-x₂)>x₁+x₂ is constant, then what is the range of values of the real number a?"

Chen Ye and Lin Zimo, who were standing next to him, glanced at each other.

Is this a new code?

Luzer thought for a few seconds, and then immediately responded, "[2/e³,+∞]. ”

"That's right, you're not one of those monsters out there!"

Li Ranran, who looked nervous, showed a smile, and her eyes turned red all of a sudden.

"How did you find here?"

She rushed over to hug Luze.

But Lu Ze was ruthlessly dragged aside by Chen Ye.

"That's the end of the code, isn't it?"

Chen Ye held a compound crossbow and landed in front of Li Ranran.

"And how do I know if you're a mutant?"

"Who are you?" Li Ranran stood still, her expression cold, "How do you want to confirm?" ”

Chen Ye smiled faintly: "Join my survival team and answer some of my questions." ”
