Walking out of the ice cave, there were still wurm corpses outside, with no claws and traces of bites, obviously all of them were killed by Zhao Nan in one move.

"I walked in from this cave before, so why don't you choose this side now?" Zhao Nan said, pointing to the side.

Audrey took a look, and saw that there were many caves in front of her, and there were more than a dozen of them in a rough count, each of which was three or four zhang in size. She looked at Zhao Nan and asked, "What kind of place is this?"

"Didn't you say it? This is the dragon's lair, and I guess it's the headquarters rather than a branch. "Zhao Nan didn't have a good airway.

"Strange, this kind of terrain looks good. Audrey touched her chin and muttered, she looked at the environment in front of her, somehow it felt familiar, but the light here was always dim, so it was difficult to judge.

"Let's go. ”

Zhao Nan's voice sounded, and before Audrey could react, he had already chosen the direction he just said and left, and Audrey had no choice but to follow.

The two of them looked for the way down, Zhao Nan walked in front, he took out the flashlight and was responsible for lighting, this kind of thing was naturally bought from the system mall, and it was also used by the dragon tide chased into the ice valley before.

Along the way, the layout is basically the same, with more forks and caves in front of each exit. The two of them were like digging into a cave in all directions, going in from one to the other. It wasn't until I walked through a narrow black passage that the scene in front of me changed.

The unimaginably large space was filled with ice cubes hanging upside down in mid-air, and the smooth ice walls were filled with caverns of various sizes, which looked similar to the dwarven caves built in the middle of the mountain, except that the surface of such caves was covered with layers of ice.

Zhao Nan and the others happened to come out of a certain cave and were located in the middle of this space. Not up or down. Crawling on the edge of the cave, I looked at it and suddenly felt a sense of horror.

"Ah, I know what this place is. Suddenly, Audrey shouted.

Zhao Nan was startled, glanced at her and was about to speak a lesson, but she said anxiously: "This is the underground of Nova Vein. ”

"Nova vein?" was infected by her emotions, and Zhao Nan was also stunned for a moment.

"Yes, the terrain here is clearly an underground vein cave connected by Nova veins, and those caves should have a lot of veins running through them, but now they ......"

Audrey said. While carefully looking at the caves on the ice walls, but all the caves were empty, and where were the Nova veins?

After Audrey said this, Zhao Nan suddenly had some impressions, if he remembered correctly, he had seen the so-called Nova vein under the Whisperer Corridor more than half a year ago. At that time, Zhao Nan was still entangled in the silver silk thread called Nova Vein, and as a result, he inadvertently absorbed the magic contained in it. As a result, mental power has increased by a full 1,000 points.

"Strange. Where has the veins gone here?weishenme is gone?" Audrey said with a panicked face.

"Wait, if you say that this is the Nova vein, then the first Nova Wall destroyed by the Golden Dragon King is also here? Zhao Nan guessed.

"Impossible, the Nova vein is the embodiment of the divine power of nature, it is formless and indestructible. Even if they are dragon kings of giant dragons, they can only cut off the veins at most, and make the wall of Nova on the ground, which originally protected our territory, disappear, and it is impossible to make the veins of Nova deep underground disappear. Otherwise, in this northern war, the forest arias in the clan would not have proposed to repair the Nova vein. Audrey shook her head.

"But how do you explain the current situation?" Zhao Nan pouted.

Glancing at the bare caves, the elven girl looked melancholy.

"Okay, don't think about it, isn't it up to the elven priests of your clan to fix the problem of Nova vein? ”

With that, Zhao Nan summoned the roaring tiger beast from the pet pen.

Audrey thought it made sense, so she followed Zhao Nan to fly up to the top of this space on the roaring tiger beast, hoping to find an exit back to the ground from above.

This space underneath is really a little terrifying, although Zhao Nan didn't let the roaring tiger beast fly at full speed, but from the moment the cave flew out just now to now, it took nearly ten minutes to actually not fly to the top, he roughly calculated, this height is at least close to a thousand zhang.

It took about another ten minutes to reach the top of the space, but unfortunately, there was nothing but a dense pile of ice cubes hanging upside down.

Zhao Nan tried to let the roaring tiger beast fly along the top to see if he could find the exit, but it flew like this for another ten minutes, and the result was nothing but ice cubes.

"It seems that there is no exit here. Audrey said with some pity.

"Why don't you blow an exit from here? Zhao Nan clenched his fists with an eager expression.

Seeing this, Audrey hurriedly stopped: "Don't, there is an underground vein cave connected to Nova veins near here, if you open a hole from the top, what if the entire underground cave collapses?"

Audrey has already seen a lot of Zhao Nan's violent methods, she is not worried that she will be buried, but she is afraid that this will mess up the opportunity to repair Nova's veins.

Considering that one of his tasks was to plant a new shijie tree, Zhao Nan thought about it and felt that it was not appropriate to take risks, so he still dismissed this idea.

Audrey breathed a sigh of relief.

At this moment, the roaring tiger beast that flew into the air suddenly let out a low whine, which attracted the attention of the two of them, and they followed the sound, and a shocked expression appeared on their faces at the same time.

I saw that there was a light cluster in the middle of this space that was circular, with a diameter of a few miles, although it was a little vague and dim, but it seemed unfathomable when you looked closely, and the halo emitted by the edge was slowly turning, and there was a strange feeling that sucked people into it.

"What's that?" Audrey cried out with wide eyes.

Zhao Nan suddenly regained his composure, because Brother System had already helped him answer this question.

System: Discover the Gate of Breaking Boundary, and after using merit points, you can reach another dimension through the Gate of Breaking Boundary.

Seeing the information popping up by the system, Zhao Nan was excited. Although he didn't know what this other space was, even if there was a 1 in 10,000 chance that he might return to reality, he would try.

It's a pity that Zhao Nan didn't have the merit value required for the portal to break the boundary at all, and he triggered the merit task from Loki half a year ago, but because of the disappearance of this kid, it has not been completed until today.

However, Zhao Nan didn't want to let it slip away in vain, so he didn't want to, and directly let the roaring tiger beast carry him closer in the direction of this gray light cluster.

"Hey, you. What are you doing?" Audrey was frightened, and although she didn't know what the gray light was, it was clearly not a good thing judging by the strange sensation it emanated.

"I'm going to make sure of one thing, jump in if you're afraid. ”

"Bastard. How do you tell me to jump?" Audrey glanced down, a thousand feet into the air. I can't even see the ground clearly. Wouldn't this jump be shattered?

Zhao Nan was very urgent at this time, and he didn't have time to pay attention to Audrey's protests, so he directly let the roaring tiger beast fly at full speed, and came to the front of the gray light cluster in the blink of an eye.

As soon as you get close to the light cluster, the system suddenly pops up an option in a prompt box.

System: Do you want to spend 500 merit points to travel to another dimension (Note: You can teleport without using merit points, but there is a danger of being crushed by the space storm.) Attention players. ）

Yes/No.

Seeing this option prompt, Zhao Nan was both excited and disappointed, excited that the question of where to use the merit value was finally solved, and he was disappointed. He didn't have any merit worth meowing, hey?

"You can forcibly teleport, but it will be crushed by the space storm?" Zhao Nan noticed the detailed remarks in the back again, and hesitated a little in his heart, although he really wanted to find a way to go back, but after all, it was not certain whether the other space was realistic or not. If you are teleported to a place where other birds don't poop, I'm afraid it will be even more of a headache.

Besides, no one knew how powerful this space storm was, and Zhao Nan didn't dare to try it indiscriminately without merit points. Thinking of this, Zhao Nan sighed, and he decided to think about getting 500 merit points before calculating.

"Zhao Nan, do you see something running out of it?"

Suddenly, the elf girl who had been sitting behind Zhao Nan let out an exclamation. Zhao Nan came back to his senses and looked up, and couldn't help but open his mouth wide, because he clearly saw a group of wurms running out of that gray light cluster.

There are many types of wurm systems, some climbing, some flying, and the number is even thousands, which is almost the same as the dragon tide that chased and killed Zhao Nan and the others before.

"How could so many dragons come out?" cried Audrey with a pale face.

Zhao Nan just wanted to keep the roaring tiger beast away from the gray light cluster, but a magical scene appeared, only to see those wurm species, whether they were flying or reptiling, all of them drilled out of the gray light cluster, and their bodies seemed to have lost gravity, supported by an invisible liliang, floating to the top of the space.

That place was originally hung upside down with a piece of ice, but at this time, a white light suddenly appeared, and a teleportation array with a diameter of 100 meters suddenly appeared under those ice cubes.

There was no doubt that the armies of the wurm system that ran out of the gray light group disappeared through the teleportation array, and it took about half an hour or so until a wurm disappeared from Zuihou, and the teleportation array gradually hidden.

"It's a pity, I knew that we would teleport out, and that teleportation array should be able to go back to the ground. Audrey watched it for a long time, and suddenly said such a sentence with regret on her face.

"Go out with the army of the Wulong system?Your brain is in water, do you still want to experience the experience of being chased and killed by the dragon tide?" Zhao Nan said angrily, this kind of problem is up to her, if this is okay, I'm afraid the first problem after going out is how to escape from the encirclement of the dragon tide.

"I'm just talking about it. Audrey let out a grieve of disgrief.

Zhao Nan ignored her, looking at the gray light called the "Gate of Breaking the Boundary" in a daze, he was completely disappointed at this time, if he was not mistaken, the different space that the system refers to is probably the abyss plane where the dragon originally lived.

If it was that kind of place, Zhao Nan would not go to death.

......

Not to mention how disappointed Zhao Nan was, because he didn't know that Shijie on the ground, the war between the Terran Elf Clan Alliance and the giant dragon had begun.

The wurm army that escaped from the Gate of Breaking Boundaries was teleported to the ground through the haode teleportation array that had been set up for a long time, and they quickly joined the battlefield to tear apart the Terran warriors and elven warriors who resisted them.

On the side of the alliance between the two races, the sound of trumpets rose and fell one after another, and teams of Terran warriors or elven warriors wearing various armors poured out from one square after another. They were armed with spears and swords, and they attacked directly according to each formation, and their expressions were extremely solemn.

Behind the warriors, high platforms have been erected, on which stood groups of magicians with staffs, they held their staffs high, and the chanting of spells sounded, and all kinds of magical light emerged.

Fireballs, Lightning, Ice Picks, Wind Blades......

Above the sky.

The elven dragon hunter beast cavalry of the elven clan and the griffin cavalry of the human race are also fighting, their opponent is an endless group of flying dragons, the two sides are constantly fighting in the air, a flying dragon spews out all kinds of flames, the cavalry hurriedly resists with a shield, a swooping blade is inserted into the throat of the flying dragon, he has not had time to cheer, several flying dragons have surrounded him, the screams sounded, and a piece of flesh and blood fell like rain.

The war was fought on the Crystal Ridge, and the time had lasted for a day and a night, and I saw that the mountains were all over the field, and the ground that had been white was stained red with blood, and the blood coagulated at low temperatures, turning into pieces of blood-colored ice.

Dozens of miles behind the battle group, two black shadows were suspended in the air, they didn't make a move, they looked at the battle below coldly, just pinned each other down.

"Is this really good, Makodo?" asked the taller figure as he approached the others.

"Don't worry, everything is in the hands of the general, and our attention only needs to be focused on the other party's commander in this war. Makodo said confidently.

"I hope so, after all, the other party has seven saint-level powerhouses, and it won't be too easy for us to deal with, if even the battlefield is contained, this is not a good thing. The taller figure said coldly.

"Sauron, don't worry, I even called those two guys to keep those seven people behind. Makodo laughed.

"What? You said they? How is this possible? Will the Green Dragon King approve it? After all, they also have to guard another Boundary Gate, and if something happens, they can't afford it. Sauron cried out.

"The fact that the two of them can come shows that there is the approval of the Dragon King, what are you worried about. Makodo shook his head helplessly and explained to his friend's overreaction to his friend's overreaction.

"That's fine. Sauron nodded, a gleam flashing in his eyes, and muttered, "If even the two of them came, then Jihua would be foolproof this time." (To be continued......)
