"Boom!!"

The rats went crazy, and Zhou Chen was ruthless, as if adding fuel to the fire, and the area of the golden flame expanded several times.

In order to rush to the trio, the rats had to pass through a ten-meter-long flame passage, which was almost the length of the two sedans connected from end to end.

These virus infections are very fast, but the power of the Pure Demon Fire at the two poles is terrifying, and the speed of their entry into the flame channel and being attacked by the Pure Fire immediately plummets, and then it gets slower and slower, and slower and slower......

Patches of infected virus were planted in the flames and burned to ashes by the flames.

Correspondingly, Zhou Chen's more than 200 energy values fell one by one, and if he hadn't killed a large number of mice and picked up one by one, he would have bottomed out in four or five seconds.

Overall, energy is on a downward trend.

Zhou Chen was uneasy: "Why is your body so hot?" ”

Burning a large number of plastic-grade virus infections, Zhou Chen felt that his body was getting hotter and hotter, and his body was blood-red and blood-red, looking similar to a boiled crayfish, which was not the skin color that a normal person could have at all.

"Could it be ......" Zhou Chen's eyes lit up: "Finally going to advance?" ”

Previously, when completing the Desperate Quest 'Survival', the system rewarded an Evolution or Benign Mutation, which was activated when advancing to Black Iron Level.

Thinking of Lu Manwei's high fever when she evolved, and her body temperature exploded, Zhou Chen was more and more sure that she was about to advance.

Then

"Shhh Zhang Yufei gasped: "It's so hot!" ”

The huge black ant that Zhang Yufei transformed into turned his head as he ran, looking at Zhou Chen, who was standing at the tail and his whole body was red, a pair of big eyes flashed with panic: "Brother, don't complain at this time, ah!" Wrong! Run a fever! Don't get a fever at this time! It's going to die! ”

Zhou Chen heard Zhang Yufei's strange scream, and when he raised his foot, he found that the place where he was standing was obviously red, like a red-hot piece of iron, which was incompatible with the surrounding black carapace.

"It's so hot?"

Zhou Chen was terrified.

Metal war ants are black iron-level lifeforms, their carapace is as hard as iron, and it takes at least hundreds of degrees Celsius or even a thousand degrees to burn iron red in a short period of time.

That is, the internal temperature of the household stove.

"When Lu Manwei evolved, her body temperature was not so high."

"My body temperature is higher, does it mean that I am stronger than Lu Manwei after evolution or benign mutation?"

At this thought, Zhou Chen was extremely excited!

Lu Manwei's terrifying strength is still fresh in her memory, and a tornado envelops the skyscraper inside, easily destroying thousands of virus infections.

Who doesn't yearn for such power?

In the sound of Zhang Yufei gasping for cold air, Zhou Chen moved his feet to change positions.

The red-hot black carapace quickly cooled, and in two or three seconds, it became swarthy.

Zhou Chen said secretly: "Fortunately, the shoes are one of the components of the E-level boutique snake print suit, with good thermal conductivity, and the soles are a little soft, but they have not melted." ”

After the bipolar pure demon fire, the number of rats decreased sharply.

After a while, the large army of rats was wiped out, and only scattered gray squirrels rushed in from all directions.

Zhou Chen cut off the two poles in time and jumped to the ground.

A gray fluttering mouse swooped down in the air and slashed into two pieces with a sword in his hand.

"Why haven't you advanced yet?"

Zhou Chen was secretly anxious.

When he advanced to the plastic level, he killed hundreds of plastic-level virus infections in a bloody battle.

The energy provided by twenty or thirty plastic-grade is equivalent to one black iron level, and the number of rats is not as terrifying as imagined, only thousands, which is equivalent to dozens of black iron grades.

Coupled with the black iron-level monsters killed along the way, the total number is at least two hundred.

Even if the higher the level, the more energy is required to advance, that's pretty much the same, right?

This is a main road, there is no end in sight, the bronze virus infection in the depths of the street is coming, with his current strength, even if the hole cards are exhausted, he may not be able to fight.

"Squeak!!"

A high-pitched scream rang out from the depths of the street.

Listening to the sound, it was closer to Zhou Chen and the three of them than the last time they screamed.

Zhou Chen was anxious: "Hurry forward!" ”

"Squeak!"

Another bang.

This time it's closer, and it sounds clearer.

"Squeak! Chirping! Chirping......!! ”

A series of screams were formed, as if someone was speeding a car and honking its horn intermittently, rushing over the area.

At the same time, the palpitating coercion has increased dramatically.

Zhang Yufei scolded: "If you are going to die, you are going to die, he is ma, the big boss is coming, who can withstand this." ”

Zhou Chen's body was red, and he gritted his teeth and said nothing.

Brush!

Chirping!

Laugh at!

He raised his sword and desperately slashed the virus infected, expecting to advance to the Black Iron level and evolve successfully.

No, it should be said that the benign mutation was successful.

The difference between evolutionary life and mutated life is –

Evolved lifeforms have mysterious and unpredictable abilities, such as Lu Manwei manipulating storms and evolving blood orchids with wide and efficient healing, while mutant lifeforms are physical changes, such as Lin Wanyi's regenerative cells and malleable torso.

Zhou Chen is about to advance successfully, except for his hot body, there is nothing else abnormal.

Referring to the scene of Lu Manwei's evolution, nine out of nine are benign mutations, not evolutions.

"Benign mutations are also OK, advanced advanced ......"

An obsession surged in Zhou Chen's heart, and his eyes were red and he was killing wildly!

"Squeak!!"

Another scream, a bronze life appeared!

"In the air!"

Zhou Chen immediately looked up when he heard the voice.

At the height of the three-story building, a giant black rat about the size of an adult flew from far to near, with a tail longer than its body and a thick wrist, like a condensed steel whip flailing around in an S-shape behind it.

Counting the tail, the giant rat is more than four meters long, with short black shiny fur like mink fur clinging to the surface of the skin, and a pair of bony wings burrowing out of its ribs, and between the bones is a thin blood-colored flesh membrane.

【Ding~】

【Trigger Mission: Counter Battle】

[Mission Level: F Rank (Hell)]

[Quest content: Kill the Winged Thorn Rat]

[Mission Time: None]

[Reward: 1 Synthetic Blueprint]

[Quest Punishment: None]

[Do you accept the task?] Countdown to 5 ......】

"Accept!"

Hell missions are more difficult than nightmare missions, as it's much harder to crawl out of hell than to wake up from a nightmare.

Moreover, the potential meaning of the unpunished task is that if this task is not completed, then Zhou Chen has already died in this mission, and the dead do not need to be punished in any way.

Only on very difficult missions will there be 'Mission Penalty: None'.

This 'none' is an extreme red flag!

"Identification!"

【Winged Hedger】

Grade: Bronze

Skill: Stinger Spray

Stinger Spray: A pitch-black stinger containing 'rickettsia enhancement' germs is sprayed into the mouth to attack the target.

……

The two-winged hedger saw Zhou Chen and the three of them screaming and swooping straight down, crashing headlong into the largest metal war ant with ten thousand momentum!

"Rub!"

Zhang Yufei was so frightened that his soul flew out of the sky.

He wasn't flexible enough to dodge after his transformation.

"Metallized!"

In an instant, the black giant ant turned golden and shimmered in the sun.

The golden ant is nearly ten meters long and four meters high, which is larger than the container truck pulling the container.

"Boom !!"

There was a loud bang like iron.

The huge golden ant stuck its six legs into the grass to meet the impact, and was hit by the two-winged hedger and slid backwards for two or three meters, and six half-human deep gullies appeared on the ground, and the soil on both sides of the ravines rolled up.

After Zhang Yufei used metalization, he was an iron pimple, and Rao was like this, and he was also hit by a two-winged hedger and screamed, and his head was full of blood and desperately retreated.

“biubiubiubiubiu！”

The body of the two-winged stabbing rat froze in the air, and Zhou Chen seized the opportunity to pull the trigger one after another, and all five crossbow arrows were shot out, triggering the passive skill of the Ice Crossbow Frost Freeze.

The winged hedger suddenly stiffened, like a large flying toy that had been pressed the pause button and fell from a height of one story in the air.

Zhou Chen did not hesitate to use the first killer feature!

"Frost Burst!"

The only skill of the energy weapon, the Ice Crossbow, consumes all the energy in the Frost Drive to launch an explosive attack.

In an instant, Zhou Chen heard a slight hum as the energy weapon was charged.

The dark blue frost drive behind the ice crossbow turned white in an instant, and all the frost energy inside was poured into the crossbow arrows in the arrow slot, and the crossbow arrows turned blue and blue.

The air suddenly became a little oppressive.

The next moment

"Whew!"

In a piercing scream, a blue crossbow shot out!
