A thick black mist would erupt from every zombie that was killed, and all healing system users stood at the front of the city wall and began to release their abilities against the black mist.
When the white healing ability touches the black mist, it can purify the black mist. Originally, if this battle mode started with water-type supernatural beings, it would be more convenient to bring all the black mist underground with water to purify it.
It's a pity, this time I met a zombie with ice ability. If the water-type power user makes a move, it will bring greater convenience to the opponent.
Su Yunxi's purification ability is undoubtedly the greatest, but the 200,000 zombies are not only able to produce black mist when they die and explode. Those zombies that have reached level two or even level three have even appeared to be able to manipulate viruses.
How else can I say that the living space of human beings is getting smaller and smaller.
When the black mist became thicker and thicker, Su Yunxi gritted his teeth and had hundreds of clean secondary crystal nuclei in his hand. Even if it was him, it was all his savings.
Pack those clean secondary crystal nuclei separately in bags, and let the person next to them throw them out with a fishing rod. The speed at which the secondary crystal nucleus absorbed the virus was finally comparable to the production speed of the zombie army.
The blackened crystal nuclei were taken back for Su Yunxi to purify, thrown into the space, purified and then separated.
In just half an hour, Su Yunxi's side caught the attention of the zombie brother over there. No matter how fierce the firepower is, it is impossible to cover it in all directions, and no matter how fierce the firepower is, it is impossible to completely stop those undead creatures.
In just half an hour, several points on the city wall had declared a defensive failure. The rapidly tightened team finally started a 'hand-to-hand fight' with the zombies.
Sweat trickled down Su Yunxi's forehead, and he had never squeezed his limit so desperately. Yu Bai stood aside to protect Su Yunxi, but he didn't make a move.
As the highest force value on the human side, Yu Bai could only preserve his strength to the maximum extent when the leading zombie did not make a move. The current intolerance will only cause greater losses.
The scarlet eyes of the leading zombie became more and more bloody in front of the camera. When human blood began to scatter on the ground, the sky was filled with the smell of fresh blood, the fourth-level zombie howled into the sky, and rushed towards the human.
Yu Bai finally made a move, and thunder and lightning flashed between his fists. From the size of a fist to the size of a football, the thunderball that surpassed the size of a washbasin finally smashed towards the direction where the fourth-level zombies were running.
The thunderball began to explode in mid-air, and when it was hundreds of meters away, it was already a power grid. The fourth-level zombies stopped suddenly, standing outside the attack range of the power grid. In the power grid, thousands of zombies were instantly wiped out.
The metal that came out of the ground at some point meandered to the feet of the fourth-level zombies, and the residual current struck out again along the metal.
"Roar!~" The fourth-level zombie whose hair was bristling and whose suit had become tattered was stunned for a moment. With bloodier eyes, he let out a roar, and the roar made the attacking zombie group even more crazy.
A roar, even at that moment, made everyone's movements stiffer.
Before the humans panicked, a huge fireball slammed out from a distance of tens of meters to Yu Bai's right hand. The fireball did not turn into a power grid halfway like the previous thunderball. But the high temperature carried by the extremely condensed fireball directly baked and cracked the ground, and the zombies it encountered turned into fireballs to continue to grow the fireball.
Su Yunxi took the time to glance at Huangfu Aotian on the right, and couldn't help curling his lips when he saw the surprised gaze of the other party after being stunned. As expected of the original male protagonist, he was upgraded in one blow.
The attack with all his strength allowed Huangfu Aotian to break through some kind of shackles. Instantly upgraded to level three, the energy in the body is not only more, but also fully recovered.
The kind of fireball just now, he can do it ten more times!
The attack of the fourth-level zombies was blocked again. With a roar, the ten third-level zombies who had been lurking in the zombie group no longer hid, and came directly towards Su Yunxi's direction.
Su Yunxi acted as if he didn't see it, and continued to purify the virus in front of him according to his own steps. The Wang Lian in the space was also revolving rapidly, and the originally calm lotus leaf began to fluctuate a little. The faster and faster purification speed made the secondary crystal nuclei, which originally took an hour to purify, become half an hour to purify.
Su Yunxi used Wang Lian to purify the crystal nucleus, and also used his own power to purify the virus in the air. Pieces of white energy spewed down from the city wall around, and it was the healing system practitioners brought over who were working hard.
Yu Bai blocked the attack of the fourth-level zombies twice, and Huangfu Aotian blocked it once. The two men didn't talk or even meet their eyes, but they cooperated perfectly.
However, from Su Yunxi's point of view, the main thing is that Yu Bai didn't think about extra effort.
Being blocked one after another, the fourth-level zombies stood a thousand meters away and started roaring again. This time, the temperature between the surrounding world dropped even more.
Huangfu Aotian didn't know where he got the inspiration or what, he didn't attack with fireball, but he built a fire wall under the city wall. The turbulent wall of fire not only made the temperature on the edge of the city wall rise rapidly, but also caused fatal damage to the zombies whose bodies were almost devoid of moisture.
In a sense, the fire ability is indeed more suitable for dealing with zombies than the thunder ability.
It seemed that the human beings had the upper hand for only half an hour. Su Yunxi Yu Bai and Huangfu Aotian did have the capital to gain the upper hand in the battle. But those who helped intercept the third-level or even second-level zombies were failing steadily.
In half an hour, everyone went down the city wall and began to retreat quickly. After Su Yunxi, Yu Bai, and Huangfu Aotian broke through, the mine bombs that had been kept before were unceremoniously bombed again.
In two hours, the number of zombies killed has exceeded 50,000. It's a pity that there are at least 150,000 zombies left.
On the human side, the number of casualties has also exceeded three digits. It seems that there is little in comparison, but human beings are non-renewable combat power, and zombies...
As long as those casualties are not wiped out in the end, I'm afraid they will all turn into zombies and turn to deal with their former teammates.
Humans 'run away' at an exceptionally fast speed. When Su Yunxi Yu Bai and Huangfu Aotian also 'run away' quickly, the level 4 zombie who had been completely enraged chased after him irrationally.
It will never let go of those tiny bugs!
When everyone rushed to the back city wall, when 150,000 zombies poured into the city. When a fireball from Huangfu Aotian hit it, the mine that had been planted long ago exploded.
It is enough ammunition to blow up a city, and this time it did not disappoint. One hundred thousand zombies were instantly wiped out.
"Continue to retreat as per the instructions."
The remaining group of zombies was nothing to worry about, and the fourth-level zombie couldn't break through the city's boundaries for some reason. Yu Bai gave the order decisively, and the official commander didn't talk nonsense, and directly led everyone to drive back.
After the three of Su Yunxi broke up, Su Yunxi pinched three secondary crystal nuclei on the back of his right hand to quickly absorb energy. Biting the tip of his tongue fiercely so as not to make his body tremble, just when he thought he could fall to the ground with just one more movement, Yu Bai wrapped his arms around his waist with one hand.
He didn't say much, and dragged the person away with half hugs and half hugs. Su Yunxi breathed a sigh of relief, unceremoniously pressed his whole body weight on Yu Bai's body, grabbed two crystal nuclei on the left and right, and began to recover quickly.
"This is an opportunity." Huangfu Aotian stood beside him, looking in the direction of the fourth-level zombies. His face did not look like a shrewd businessman in the past, and he licked his lips bloodthirsty.
Yu Bai nodded decisively, but glanced at Su Yunxi with some hesitation. Su Yunxi rolled his eyes at Yu Bai angrily, and squeezed Yu Bai's waist again.
The corners of Yu Bai's mouth rose slightly, and when he raised his head again, there was the same strong fighting spirit in his eyes.
Huangfu Aotian was stunned for a moment, his eyes became darker. After taking a quick look at the two people hugging each other, they quickly rubbed the thumb and index finger of their right hand.
Even in this desperate time, there are people by my side.
Tsk.
The fourth-level zombies came over quickly, and the other supernatural beings and soldiers who were also left behind, under the command of the two commanders, avoided the attack range of the fourth-level zombies, and only cleaned up those low-level zombies.
Yu Bai and Huangfu Aotian rushed out at the same time, and Su Yunxi, who recovered most of his strength, retreated more than ten meters. The sea of fire and the power grid blocked all the attack directions of the fourth-level zombie, and Su Yunxi unceremoniously threw a huge and thick white mist on the fourth-level zombie.
"Oh!~" The scream was completely different from the previous roar, which made the zombie's eyes even more blood red. After being purified, black liquid like pus overflowed uncontrollably.
It looked extremely disgusting.
Two third-level mid-terms and one third-level early stage. Under normal circumstances, such a combination really has little chance of winning against a level 4 zombie, but among the three, one is the original protagonist of this world, and the other is the villain who can survive to the end of this world. There is another one, which is the alien that the world has begun to recognize.
The abilities of the three people happened to be the natural enemies of the zombie virus. The combination of two controls plus a powerful output successfully stumbled the footsteps of the fourth-level zombies.
"Be careful!" With a hoarse shout, Su Yunxi only had time to roll on the spot. Unless it is a last resort, he will never let people advance.
Of course, if life is in danger, that's another matter.
A huge figure stood in front of Su Yunxi, and a third-level zombie appeared from nowhere and waved its paw across the man's face.
Red blood, with a piece of flesh and blood. Su Yunxi's mind went blank for a moment, and the belated panic made his scalp tingle and adrenaline explode.
A purple arc mixed with white balloons hit the zombie at the same time, and the zombie turned into a pool of black water without a sound.
Wei Shi turned his head, and even had the mood to smile at Su Yunxi. There were scary wounds on his face, as if he couldn't feel any pain.
Su Yunxi wanted to help with treatment, but Wei Shi avoided it instead.
Seeing that Wei Shi's life was not in danger, Su Yunxi was so angry that he threw himself into the battle again. When Su Yunxi once again enveloped the fourth-level zombie with a milky white light, Yu Bai and Huangfu Aotian exerted their strength at the same time, releasing the strongest blow with all their strength.
After a long time, the zombies in the distance began to wander aimlessly. Yu Bai and Huangfu Aotian took a big step back uncontrollably and began to pant heavily. Less than a hundred meters away, a gray corpse lay on the ground.
Li Xiao got out from nowhere, rushed to the side of the corpse and directly opened the skull to take out a crystal nucleus the size of a fist. Before Huangfu Aotian could react, he had already turned around and handed it over to Su Yunxi.
Huangfu Aotian opened his mouth a bit, but in the end he didn't make a sound. Su Yunxi backhanded and threw two third-level crystal nuclei towards Huangfu Aotian, and then put away the fourth-level crystal nucleus.
Li Sansheng blushed and drove over, looking at Su Yunxi full of apology. Although in the original plan, he did not have the task of protecting Su Yunxi. But when Su Yunxi was in danger before, Wei Shi, who was also of the strength department, could rush over, but he was still thousands of meters away in the rear to help and only transfer.
No matter how you say it, I feel that it is my fault.
Su Yunxi fell to Yu Bai's side, and Yu Bai picked him up. Walking up to Li Sansheng, Su Yunxi angrily threw the earphone crystal core and smashed it. "Hey, hey, put away your crying expression, okay, I'm not dead yet."
Yu Bai also kicked three times vigorously. "Just complete your own tasks, and I will protect my people myself."
Without finishing speaking three times, Li lowered his head and wiped his eyes fiercely. Li Xiao scratched his head with embarrassment on his face. After all, he and Li Sansheng were the only ones brought back this time, if something really went wrong with Su Yunxi, it must be their negligence.
However, Li Xiao always has a more active mind. He walked quickly to Wei Shi, grabbed him and took him to the car together. "Thanks to you before, brother."
Wei Shi squeezed out a stiff smile, but followed Li Xiao's strength and got into the car together.
Until his subordinates came over, Huangfu Aotian, who was standing still, turned and left while holding the crystal nucleus in his hand. There was no usual smile on his face, and his eyes became a bit deeper.
