When everyone usually performs patrol tasks and clean-up tasks. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The most encountered is the mutant rat, and this large rat is the most common native mutant creature.

But generally speaking, the mutant rats that can be encountered in the city can be as few as three or five, and at most a dozen, which is already incredible.

It's like now, it's like a mountain of rats consuming the sea, and it's endless to kill it.

"Not strange!"

"Ordinary rats only need 2~3 weeks from pregnancy to calfbearing, and young mice can mature and reproduce in 2 months. ”

"A litter of female rats can give birth to 8~12 mice, and can reproduce 8~10 times a year, according to the limit number, a pair of breeding rats can reproduce 120 offspring a year. ”

Su Xiaoke habitually popularized science: "But if you take into account the reproduction rate of their offspring after maturity, a pair of breeding mice will become ...... after a year."

Everyone was shocked into a cold sweat just thinking about it.

Even Bai Yuxi's brain couldn't turn around and calculate how many rats there were!

(Ma note: Who can figure it out? I'm confused anyway.) ）

"And according to the research institutions of various countries, the study of native variant organisms (en-uma). ”

"Mutant rats are more than three times faster than ordinary rats in terms of reproductive ability and growth rate!"

Su Xiaoke said slowly: "That is to say, mutant rats can give birth to cubs 4 times in a month, 48 times a year, and young rats can mature and reproduce in 20 days......"

"Even-bought karma!"

"Sue, don't say it! I can't stand it!"

Maya finally couldn't help but scream, and Luo Fei and Xia Yuyu next to her also nodded desperately with a frightened face.

Even if they all become overrun warriors, they are still girls after all, and it is not easy to have the courage to destroy mutant rats.

Thinking of the overwhelming picture full of rats, several girls suddenly involuntarily shivered goosebumps!

You know, rats are one of the biggest natural enemies in girls' nature!

"What's there to be afraid of?"

Su Xiaoke looked disapproving: "If I guess correctly, there must be a rodent creature in Hualan Mountain that has reached the 'king-level' mutation level!"

"As you know, the pheromones and X-particles carried by dimensional creatures attract and infect similar native creatures in the vicinity. ”

"At the same time, for the native mutated organisms with their own pheromones and X-particles, there is a natural relationship between the upper and lower levels to a certain extent. ”

Su Xiaoke explained: "And mutant organisms also have the ability to attract and re-infect ordinary creatures of the same kind, and this kind of virus-like transmission has formed an 'ant colony effect......' between dimensional organisms and mutated organisms, mutated organisms and ordinary organisms."

The female scholar who is a good teacher has begun to say things that everyone doesn't understand again.

Everyone decisively expressed their silence, and buried their heads in desperately shooting mutant rats scurrying all over the ground.

But even if everyone played their fastest hand speed, they still couldn't stop the tide of rats.

After a few scrambling close shots, the chicken leg suddenly snapped and slapped his bald scoop.

The crisp slap caused everyone to look at him in astonishment.

"Are we all stupid?"

"So many rats, and you still shoot hair?"

I saw that the chicken leg threw the sniper crossbow in his hand to the ground in annoyance, flew up and threw one at his feet, and kicked the big mouse that was going to climb up along his trouser leg, and said depressedly: "Copy the guy directly!?"

Seeing the chicken leg pick up the square shield hanging behind his back, he smashed it down to his feet with a "snap!", and a guy shot several mutant rats to death!

As soon as the chicken leg was reminded, the people who were numb to shoot rats reacted, dropped their sniper crossbows one after another, took out their respective weapons and rushed forward, kicking and kicking, it was indeed much faster than they were shooting one by one!

Bai Yuxi, who was still squatting on the tree, looked at the sniper crossbow in his hand that had been emptied of marbles, and was also speechless for a while, jumping directly from the battle platform!

The white jade seal that fell in the middle of the rats, a huge round shield-like light flashed under his feet, and he heard a squeaky scream, and he was immediately trampled to death!

"Huh?"

Bai Yuxi originally only used one or five shields to cushion the impact when jumping from a height, but he didn't expect this effect.

In addition, with the size of a mutant rat, it was indeed a little inconvenient for him to bend down to attack, so he simply jumped up again, jumping around like a rabbit, and shouting in his mouth: "Thousand and one two, one hundred and fifty five, chain shield rebound!"

The X energy level released by the "Thousand One Two, One Fifteen Five, Shield" was only more than thirty degrees, and it couldn't hurt everyone in the seventh squad who had been promoted to F4 and F5 levels at all.

Therefore, Bai Yuxi didn't care about them when he jumped up, and there were many rats there, but the energy ripples generated when the fifteen shields were released undoubtedly interfered with everyone's actions.

When attacking, he is so ashamed to shout the name of the move.

The second middle school made everyone can't help but get goosebumps, and they are immediately angry!

Xia Yuyu was the first to go crazy, touched the waist bag behind her waist with her backhand, grabbed a lot of iron thorns, and smashed her head and face at the rats, and also shouted: "Rainstorm pear blossoms, silk rain!"

Although it is difficult for Xia Yuyu to control the hit rate of the iron thorn with this kind of covering blow, but fortunately, whether it is the density of the rat colony or the density of the iron thorn, it can kill many mutant rats by throwing it blindly.

A handful of iron thorns spilled out, and the ground suddenly seemed to grow like a needle carpet.

Many mutant rats that didn't hit the vital point were nailed to the ground alive, screaming and struggling desperately.

This is much more deadly and cruel than Bai Yuxi's blow, but the girls hate rats, it is from the heart, and they feel uncomfortable under the blow, and they are another one without saying a word, and they shouted again with great interest: "Rainstorm pear blossoms, silk rain, continuous!"

Bai Yuxi, who was jumping happily, almost didn't step on the short thorn on the ground, and in a hurry, his feet stepped on the air in a volley, and the layers of light shields flashed, and after a little increase in air power, he made a dangerous backflip, avoiding the needle carpet on the ground, and was shocked into a cold sweat.

Bai Yuxi turned over and fell to the ground, originally angry and planning to protest to Xia Yuxi.

But after seeing the metal spikes all over the ground, his eyes suddenly lit up, and the arc on his right arm flashed, and he slammed his fist on the ground, shouting: "Combined Attack Technique, Thousand Needles Lightning!"

I saw that a flash of lightning burst out from under Bai Yuxi's fist, bouncing and wandering on the ground, attracted by the nearby iron thorns, and one by one formed a large piece of power grid covering the ground!
