Walking to the front of the passage to the south, Aurora still made some explanations: "Do you know the five elements of gold, wood, water, fire, and earth? You should know. That Five Elements Demon Slayer Seal is a set of seals that gather the power of the five elements to form an infinite loop. But if you say it too clearly, you won't understand. ”

"Actually, I know a little bit about it." Gao Jin expressed disbelief and said, "The Han family is the wood in the five elements, the Ross family is the gold in the five elements, and the other three families also have their own corresponding five elements." Am I right? ”

"Huh." Aurora was surprised and exclaimed, "Oh, I didn't expect you to know a lot." ”

"A little bit of it, a little bit of it. Tell me what the hell is going on? There's a monster this time, and we'll have to join forces, I don't want to be a fool. Gao Jin quipped.

However, hearing Gao Jin say this, Aurora, who was still smiling, suddenly became a little lonely, and her eyes suddenly dimmed.

Seeing Aurora's expression, Gao Jin was also startled, and asked weakly, "Are you okay?" Actually, I don't have to know, and it's okay if I don't say it. Let's go, let's hurry up, and I'll do my best to help you. ”

Aurora turned her head and faced the passage. With a sigh, he said, "It's okay." This time, these five people sent by the five families actually inherited their family's bloodline and were born with the Five Elements element. The monster did not kill them, but controlled them, hoping to use them to open the Five Elements Demon Slayer Seal. ”

"I see, I said how the monster didn't kill them, but took them away. I'll understand when you say that, so let's go. I just looked at the markers on the map, and it seems that there are many detours to take this passage. And the exit is on the other side of the city, and the road seems to be very far. Gao Jin saw that Aurora's mood suddenly became a little low, although he didn't know what was going on, but it was not good to continue to listen to anything.

"Well, it's okay, we'll be able to catch up with them soon." Aurora's hand flashed with white light, and there was an additional black ball.

"What is this?" Gao Jin wondered.

Aurora didn't answer, and aimed the ball at Gaojin. Then a beam of light suddenly emitted from the ball, hitting Gao Jin directly in front of him. But it didn't cause him any damage, but formed a faint white light curtain on him, a bit like an aura shield, and a bit like the protective shield released by Gleyer.

"With this shield, the light net inside can't hurt you." Aurora explained, casting a shield for herself.

Putting away the black ball, Aurora shook her body and rushed into the passage quickly. I saw that the moment she entered the passage, a light net immediately appeared in the passage. But when that terrifying red beam hit the white light curtain, it was immediately reflected back by it, and it couldn't hurt Aurora at all.

Seeing this situation, Gao Jin also hurriedly rushed into the passage.

Along the way, there will be a network of light popping up in the passage from time to time. The first few times Gao Jin was startled by the light net that suddenly appeared, but he gradually got used to it, and he was basically numb when he got to the back.

At this time, the two of them exerted their speed to the limit, which was basically the speed of three or four seconds of 100 meters. Rao ran for half an hour before rushing out of the winding passage.

At this moment, the two of them were located at the southwest end of the city, and they had come out of a hole in the ground. And jumping out of the narrow passage, as soon as his footsteps landed, Gao Jin was shocked by what he saw.

I saw a huge underground cavity, and the roof of the cave was not less than 100 meters above the ground. Moreover, it is a dome poured with reinforced concrete, covering an area of no less than five or six square kilometers.

But if it's just an underground cavern, although it's huge, it's nothing. The reason why this place is an underground city is because of the view from the eye. There are straight streets, rows of buildings, large signal towers, and even two cars parked in the far side of the street.

"This place is prepared for the outbreak of a nuclear war, so that the survivors can continue to live here, and the living facilities are very complete, in fact, it is a small city." Aurora said.

"If a nuclear war really breaks out, it's useless to hide deeper. The life of not seeing the light of day can make people shudder to think about it. Gao Jin said as the white light flashed in his hand, and he took out a kettle from the storage space and drank a few sips of water.

For the sake of ease of movement, the two of them had already put their backpacks in the storage space, and they didn't have to run with weights at all.

Aurora took out the black ball and put away the protective shield on the two of them. Then it excites Saturn's rings to reveal a three-dimensional structural map of the underground city.

I saw that the red light that marked Miranda's location was approaching an area at the northeast end of the city, and the line marking that location was not green, but bold red, which looked very conspicuous.

"They're close to the seal, let's get over there!" Aurora put away the light curtain as she spoke, and ran down the street in a northeasterly direction.

Gao Jin hurriedly put away the kettle and hurriedly followed. The two of them came all the way, and their physical and spiritual power were consumed a lot, but they didn't have time to stop and rest now. Anyway, with the pill on his body to restore his spiritual power, as long as he stops the monster first, if he is really defeated at that time, it is not too late to take medicine to restore his spiritual power.

Walking through the streets of the city, the surrounding buildings give the illusion that you are in some deserted city, and that time has sealed everything here after people have left.

But soon Gao Jin didn't have time to sigh, because he saw many black poisonous snakes suddenly gushing out in front of him. There are countless dense ones, and they vary in size and strength. Some are born with wings and can fly in the air. Some of them have big heads like buckets, and their mouths are full of jagged teeth, and they look very terrifying. More are like ordinary black snakes, sticking out their tongues and wandering wildly underground.

The two men stopped and hurriedly stepped back.

There are so many of these black poisons that they are not only on the roads, but also in the buildings on both sides of the road. There were even many at the top of the building, spitting venom in the direction of the two men.

If it was one or twenty or even one or two hundred, two people could easily kill them, or even ignore them and rush straight over. But now there are more than 120,000, maybe even hundreds of thousands of black poisonous snakes. Naturally, the two of them need to be careful to avoid falling into the encirclement.

After exiting a dozen steps, the two came to an intersection. It's a relatively empty place, and the surrounding buildings are only two-story, and even if you spew venom on it, it will be too far away to hit the two of them.

At this time, among the poisonous snakes, a figure rushed over. The wave-like viper made way in the middle, and the man was in front of them in an instant.

"Jason!" Gao Jin almost didn't recognize this person, but he could still be vaguely distinguished from his distorted facial features.

I saw that Jason's muscles swelled all over his body, and the whole person was almost bigger. The clothes on his body were all burst, and he could see that the blood vessels in the muscles had protruded, and the blood that seemed to be flowing inside seemed to have turned black.

The facial features were slightly distorted, as if they had been in great pain before. The eyes bulged, the chin cracked, and black fluid dripping from the nostrils.

Holding two one-foot-long iron rods tightly with both hands, he stared at Aurora with a strange sound in his mouth, "Kill...... Kill...... Kill ......"

"He's already dead, let me deal with him! You go deal with those poisonous snakes! Aurora preemptively attacked Jason. She flashed, and in an instant she was next to Jason, swinging her dagger and slashing at his neck.

"Bell!" Jason swung the iron rod in his right hand to block the dagger, and his left hand counterattacked at the same time, and the iron rod slammed into Aurora's head.

In the impact of the dagger and the iron rod just now, Aurora already felt a slight numbness in her wrist, and she couldn't help but feel a little shocked in her heart. I don't know what the monster did to Jason to make him so powerful.

But there was no time for Aurora to think, the iron rod was already in front of her eyes. Just five centimeters from her head, Aurora's figure flashed and turned into a cloud of black smoke. In the next moment, she appeared behind Jason's back. Two daggers stabbed out at the same time, hitting Jason in the spine.

Seeing that the dagger stabbed into Jason's body was almost handleless, Jason actually took a step forward and separated his body from the dagger. At the same time, he turned around and waved an iron rod and made a counterattack.

"Bell!" Another burst of sparks.

Aurora took advantage of the collision to leap backwards and widen the distance between the two sides. However, as soon as she landed, a large number of black poisonous snakes surrounded her and launched a crazy attack on her.

Just as there was nowhere to come out of the smoldering fire, the black vipers immediately became punching bags. I saw that Aurora turned into a black whirlwind, and the black viper was instantly dismembered by the blade wherever it passed. In the blink of an eye, hundreds of black vipers died tragically under her dagger.

When the corpses of the dead black vipers turned into flames and burned, Aurora's form reappeared on Jason's left side and fought him again.

Gao Jin on the other side is not idle, his energy is the wind, and the skill he can use is the wind blade. This time it comes in handy. Faced with the swarming sea of black poisonous snakes, he could harvest hundreds of snake lives with a casual wind blade into the snakes.

Rao is wind blade is so powerful, but in the face of a very large number of snakes, Gao Jin still didn't dare to hold it up, so he could only fight and retreat to avoid falling into the situation of being beaten by the poisonous snakes.

I don't know if it's because Gao Jin is too lethal to the poisonous snake group, or because the poisonous snake group doesn't dare to get too close to Jason. In short, only a small number of big-headed monster snakes are assisting Jason in attacking Aurora, and the rest of the 199% are all chasing after Gao Jin, which means that he will not kill this person and swear not to be a snake.

Although Gao Jin was very helpless, he also found a big bargain. He used his speed to lure the serpents into running down the street after him, and from time to time he turned around and fired several wind blades.

In this way, it has a surprising effect. The group of poisonous snakes was attacked by him on a large scale, and it was very unfortunate that a large number of them died.
