The "material" added by Bai Yejia is very simple, it is the holy oil obtained from the Majin's lair in the Pansattok fault space.

Just one drop in the oil storage tank turned the oil upside down, increasing the intensity of the flame and the duration of the spray tenfold!

The holy oil is made by using the bone marrow of the demons, supplemented by special magical means, and is a precious material unique to the demons. The demons use the holy oil to communicate with the spirits of the ancestors, and for humans, the holy oil is an extremely efficient new energy, and mixing it into the existing energy fuel can improve the performance of the fuel.

A drop in the flamethrower's oil increases the flamethrower's power tenfold. Similarly, if a drop is dropped into gasoline, the energy value of gasoline can also be increased tenfold, that is, the same tank of gasoline, after being dropped into holy oil, can increase the distance traveled by the car tenfold!

Unfortunately, even for the demons, the holy oil is a rare thing, and it is even more impossible for humans to use it as a regular energy source, and can only be used on some specific occasions.

Before this battle, Bai Ye added holy oil to half of the flamethrower oil storage tanks just in case, and now it is used, and the effect is so good that it exceeds people's most optimistic imagination!

The raging flames not only dispersed the gray mist, but also caused great damage to the undead legions. The undead are cold attributes, except for a few unique species, most of them are restrained by the flames, even the skeleton guards, a high-level cannon fodder with tenacious vitality, can't last long in the flames, and ordinary skeletons and zombies are burned to death in pieces.

The flames quickly ignited the corpses in the construction site, and the entire construction site was ablaze with a sky-high fire, and the army of the undead was surrounded by flames, and countless undead fell down.

The corpse witch Clautz roared angrily, it raised its staff, slammed on the ground, from the place where the staff touched the ground, a little cold flashed, and then a large area of cold air gushed out, the surface of the ground was quickly covered with a layer of ice, and under the effect of the cold air, it pushed forward, no matter what it touched along the way, the cold air would possess the body and freeze it, even the undead army under its command was no exception.

Although the speed of the ice spread was not fast, its momentum was unstoppable, and all the flames along the way were extinguished by the cold air.

This burst of cold air spread all the way to a hundred meters away, almost affecting them in the white night, and when the cold air dissipated, the ground was already covered with ice, forming a wide ice road!

The undead swooped down the road again, and the white night once again rang out with furious gunfire, and the battle began again.

The corpse witch Klautz waved his staff, and a cold icy wind poured out of the staff, and the ice wind was mixed with countless shiny ice picks!

Bai Ye yelled: "Sister Fenghua, block it!" ”

Feng Hua on the side opened his hands, and his spiritual power poured out like water, forming a huge spiritual power shield in front of the position, and dense ice picks continued to hit the shield, resounding with a clanging sound!

The whistling ice wind lasted for a full five seconds, and the shield had flickered and flickered, and it seemed that it was impossible to hold on, but fortunately, the ice wind was finally over, and a thick layer of frost had formed on the surface of the shield, and Feng Hua's momentum was loosened, and the shield and frost shattered one after another and fell to the ground.

Feng Hua rubbed his swollen and aching temples, and said in shock: "It's amazing!" ”

White Night explained, "This is the Icicle Technique, the Corpse Witch's powerful attack spell. ”

He opened his eyebrows, pointed at the corpse witch Klautz, and said loudly, "Don't think that only you know how to spell!" After speaking, a ghostly light burst out in the vertical pupils, and a black streamer streaked across the sky and shot towards the corpse witch.

The corpse witch knew that it was powerful, and hurriedly condensed a thick layer of ice armor in front of him, and the shadow ray hit the ice, scattering debris everywhere, constantly shattering the ice and rushing forward.

Bai Ye roared, and his spiritual power was like a flood that opened the floodgates, all of which merged into this shadow ray, and the black of the ray became deeper and purer, and with a bang, the ice armor in front of the corpse witch was shattered!

The corpse witch was startled and stretched his staff forward, and the ice condensed again, colliding with the shadow ray. Bai Ye and the Corpse Witch both desperately poured out their spiritual power, and the attackers and defenders were suddenly deadlocked!

The ray of the white night lasted for five or six seconds, and the corpse witch finally couldn't hold on, and the weird skull in front of the staff snapped open, but the white night also reached the limit, and his eyes were a little bloodshot, and finally he couldn't maintain the output of the shadow ray, and with a long sigh, he withdrew the attack, and the ray dissipated into the air.

A rough sniper gun sounded in the air again, Li Bin's sniper rifle was powerful again, and the frost armor appeared on the side of the corpse witch out of thin air again, blocking the sniper, but this time it was not as easy as the first time, although the sniper was blocked, but the ice armor was also shattered and split into a block of ice!

The hand of the corpse witch Klautz was trembling, and it was finally scared. Although it has second-order strength, in order to pass through the space-time rift, it took the initiative to suppress its strength at the peak of the first order, and the current spiritual power has been exhausted, and if it continues like this, when it can't block the sniper, the time of death will come!

The corpse witch paused hatefully, and said in a hoarse voice: "Lucky for you today, the space-time rift will not suppress my power forever, and I will come back!" After saying that, he turned around and walked towards the space-time rift, looking like he wanted to escape!

Bai Ye suddenly showed a weird smile and said jokingly: "Since you're here, let's stay!" ”

As soon as the words fell, the moment the corpse witch was turning around, a cold light as black as ink crossed its neck, and the disgusting head fell to the ground in response, and then another cold light flashed, and the head split in two! The corpse witch's eyes were full of astonishment, and he didn't understand what had attacked him until he died.

After the death of the corpse witch, the icy path formed by its magic power immediately dissipated, and the fire ignited again, and just as the flames were about to completely seal the way, a shadow flashed out from the last path and appeared in front of the white night. It was a girl who looked as sweet as the girl next door, but if you looked closely at her eyes, you would find that those big eyes were looking forward to revealing a sharp cold light, like a sharp sword out of the sheath!

She was dressed in a black bodysuit that highlighted her devilish figure, and her entire right hand was wrapped in black energy, condensing into a sharp blade as black as ink.

She is Bai Ye's former classmate, Han Xue who appeared in the Qinglong Mountain incident! I don't know when she came here, using her invisible ability to lurk around the corpse witch, seizing the opportunity to burst into trouble, and actually slashed the powerful corpse witch.

She stood in front of Bai Ye, raised her head and looked at Bai Ye, the tip of her nose almost touching Bai Ye. Bai Ye looked at her nonchalantly, and after a while, Han Xue seemed to have figured out something, and finally lowered her head.

Bai Ye said lightly: "You're here, you did a good job!" ”

"Xiaoxue heard your call, came to you, and was willing to obey your dispatch."

"Okay, stop dragging words, I'm not making a movie! You helped me today, then our past grievances will be written off, if you don't want to follow me, you can leave now. ”

Han Xue thought about it carefully, shook her head resolutely, and said, "No! The world has changed, it has become so strange, I have no friends and no relatives, where can I go? White Nights, you know what? You gave me strength and avenged me, and that wretch wailed for a whole day before he died! As much as I hate him, I am grateful to you, and I am willing to follow you and become a sword in your hand. ”

Bai Ye nodded: "Okay then." Still, you have to be yourself, and if I notice the slightest sign of betrayal from you, hehe! ”

Han Xue was indifferent to Bai Ye's warning and continued: "Bai Ye, since you are already the leader of this team, what should we call you? Should I honor you as king? Or do you serve as Lord? ”

Everyone else looked at Han Xue with stunned eyes, thinking that this beautiful girl didn't seem to have a normal brain, did you travel from feudal society?

Only Bai Ye doesn't feel that there is anything wrong, after the end of the world, human beings are already scattered, and all settlements are divided and governed, not to mention being called kings, there are many self-proclaimed gods.

However, Bai Ye shook his head and said, "Do you think that with a little ability, you can survive in the new world?" In the face of those powerful beings, our strength is no different from that of ants, so surviving is my primary goal, as for the title, call me captain. ”

At this time, the battlefield has basically calmed down, and after the death of the corpse witch Krautz, the undead army has become the walking dead again, acting only on instinct, but the nature of fear of flames makes them dare not break out of the encirclement of flames, and are gradually engulfed by the fire. A handful of elite undead such as mummies and skeleton guards rushed out, but all fell under the sniper rifles.

Just a little oil can completely change the outcome of this battle. If there was no such fire, even if Bai Ye was well prepared, dozens of people would not be able to resist the impact of tens of thousands of undead, let alone win the victory unscathed.

The next time was a little boring, although the space-time rift was opened a few more times, but without the command of the high-level undead, the low-level undead only relied on instinct, neither could they assemble into a scale, nor could they know tactical tactics, and the attack like adding fuel and vinegar could not create a threat at all, and even Bai Ye and Ji Yunfei did not need to enter the battlefield, and the battle could be solved by relying on the soldiers' assault rifles alone.

And just like that, another day passed, and if you held on for another day, the great retreat would begin.

By the second day, the number of survivors rescued in the city had dropped dramatically, to less than 100,000, three-quarters less than on the first day. It is no wonder that at the beginning of the disaster, it is the stage when the most people die, but it is also the best time to escape and rescue, and the later you go, the fewer survivors and the lower the chance of survival. Maybe on the third day, the army will only be able to save less than 10,000 survivors, and if a week passes, I'm afraid that even a hundred people will not be found!

On the morning of the third day, General Feng Tiannan appeared in front of Bai Ye again.
