The south of the base city of Guangshi faces the river, and the west tower of Guangshi, where Du Fei is located, is less than one kilometer away from the river.

On the surface of the 600-meter-wide river, the river water is surging, and bubbles are constantly overflowing from the river, and layers of mist are steaming up from it, drifting north with the wind into the base city.

Twelve helicopters circled back and forth at low altitude above Base City, spraying fog repellent.

One of the helicopters rounded the West Tower and flew towards the southern wall of the base city, spraying fog repellent all the way.

The pilot was careless and drove the helicopter over the city walls to the sky above the river.

Suddenly, Ouyang Xiu opened his eyes violently, stretched out his hand and pointed to the wide river, and shouted loudly: "There!" ”

Hiss...... A sharp scream suddenly sounded, the river suddenly exploded, and a huge monster shot out of the water, straight up forty or fifty meters high, biting the helicopter in the air, biting into pieces and swallowing it into its stomach.

The base city faces the river in the south, and all the defensive forces are slightly weak, and they are mainly anti-aircraft weapons, but the soldiers on the city wall immediately reacted, and countless shells bombarded the monsters in the river.

After a burst of explosion, the huge monster fell back into the river unharmed, and the cannonballs fell on the surface of the river, making countless splashes, but it could not hurt the monster in the river at all.

This monster only appeared for less than a second, and then fell back into the river, but Du Fei had already seen the image of the monster in a real way, and couldn't help but suck his mouth.

This is one of the more famous evolutions in the previous life, huge in size, incredibly powerful, and able to release a poisonous mist.

Du Fei guessed that there might be an evolution that would release the mist, but he didn't guess that it would be this thing, it was only the sixth month of the end of the world, and it would be four or five months before he saw this thing. Everything began to fall apart, as if the world had fallen into a dislocated plane.

Du Fei didn't think much about it, and immediately said to Ouyang Xiu: "Inform everyone, bring a gas mask." ”

Ouyang Xiu's eyelids jumped when he heard this, and he immediately realized the danger contained in these words, and immediately conveyed it with spiritual communication, and after the news was delivered, he asked, "What's wrong?" ”

"That huge serpentine monster just now will release a poisonous mist. The poisonous fog is acidic, the toxin is small, the onset is slow, it is difficult to find, and when it is discovered, people in a city will be poisoned. Therefore, report to the military area, if you don't have a gas mask, cover your mouth and nose with a towel soaked in alkaline solution, and if you really don't have it, you can use urine. Du Fei didn't hide anything, and replied directly.

The name of this evolutionary is "Fog Jiao", and it was killed in the third year of the end of the world, and scientists have determined that it is an evolution formed by a snake mutation, but the degree of mutation is too great, and it is not determined which kind of snake it is.

In fact, not only the zombies formed after the death of humans can evolve into evolutionary bodies, any creature can mutate into evolutionary bodies, but human beings are more perfect than other creatures in terms of genetic evolution, so that most of the evolutionary bodies are evolved by human zombies.

However, the evolutions formed by animal mutations are usually not as intelligent as those evolved from human zombies, but they are not too stupid and have an extremely strong learning ability. Relatively speaking, in terms of strength, animal evolutions are much stronger than zombie evolutions.

From its appearance, it can be seen that it is a huge snake with a protrusion like a fish fin on its gills, which is the organ that creates fog.

After a startling glance, Du Fei could determine that the current fog Jiao had grown to a snake body fifty meters long and nearly three meters wide, and it could completely swallow a bed horizontally.

The poisonous mist released by the fog Jiao covers an extremely large area, so the toxicity is not strong, ordinary people will be dizzy within ten minutes of inhaling the poisonous fog, and in severe cases, they will vomit and faint, and they will be in danger of life if they are in the dense poisonous fog for more than an hour. The Awakened are better, but they will also greatly affect combat effectiveness.

Fortunately, most of the shelters have anti-poison measures, and the fog repellent can reduce the concentration of toxic fog very well, otherwise ordinary people will really die in the tens of thousands.

Seeing the appearance of the fog Jiao, Du Fei knew that it was time to do it himself, so he grabbed the wind sword and jumped towards the river.

"Brother......" Illya hurriedly chased two steps and called.

"Stay here." Du Fei directly ordered in a stern tone.

Although Ilia was worried, she could only stand quietly in place, rubbing her skirt constantly.

Du Fei performed the Drunken Immortal Moon Look, and in the blink of an eye, he was on the turbulent Pearl River.

It's just that it seems that Wujiao is not interested in Du Fei's dim sum, and he didn't rush out of the water to attack.

Suddenly, a red ray of light shot from the other side of the river six hundred meters away, instantly penetrating Du Fei's body and carbonizing into fly ash, which was a high-energy laser laser.

After Du Fei's body scattered into ashes, he gradually condensed his figure in another place, and couldn't help but wipe the cold sweat on his forehead.

The laser just now was too fast, and as soon as Du Fei discovered the danger, his body had already been pierced by the laser, and if it wasn't for the timely stand-in technique, he might have been seriously injured by a blow. Visually measuring the power of this laser laser, it was another level 5 evolution.

Du Fei's figure had just condensed, and another red laser shot out, fortunately, he was already on guard, and the drunken immortal looked at the moon step in succession, drawing an afterimage, narrowly avoiding this laser laser.

The laser shot into the river water, and it burned all the river water to a boiling hot, and the water vapor slowly came out.

Two level 5 evolutionaries appeared all of a sudden, and Du Fei immediately felt the pressure, relying on the combat power of the fog Jiao and this laser evolutionary body, as long as he rushed into the base city, he would immediately suffer countless casualties. Wherever the huge body of the fog Jiao is thrown, it collapses and collapses. And the laser laser only needs one shot, and whether it is the awakened or the cannon, it will immediately explode into flying ashes.

This place is only three or four hundred meters away from the base city, and using a nuclear bomb is tantamount to suicide, and the lethality of ordinary artillery shells against level 5 evolutions is really pitiful. This change immediately turned the war for the worse.

Du Fei kept casting the Drunken Immortal Moon Look, pulling out a long series of afterimages on the surface of the river.

Waves suddenly rose in the river, and the fog Jiao suddenly rushed out of the water, opened its blood basin and bit it.

Du Fei stomped on the water with both feet and dodged with a backflip.

The laser came at the right time, and the timing was very accurate.

Du Fei shook his hand and released a thick metal shield to resist the laser laser.

The laser laser burned through the metal shield with a single thud, melting the metal shield into molten iron and dripping into the river, and the laser continued to shoot straight out.

Du Fei took advantage of the opportunity of a few tenths of a second to step out of the drunken immortal moon step in the air, narrowly dodging the laser laser. Then a lilac halo appeared on his arm, and he slapped it the surface of the water.

A psychic seal immediately appeared on the surface of the water, and a huge white snake roared, rushing out of the psychic seal and rising to a height of thirty meters.

The hideous image of the white snake appeared on the river, with the snake's head held high, the horn pointed to the sky, and the stabbing armor was Ling Ran.

Du Fei stood on top of the giant snake's head, confronting the equally huge fog Jiao.

The two snakes puffed up their cheeks and blew the wind, demonstrating to each other, revealing their murderous spirit.
