"Are you really going to the outside world?" The guardian numbered No. 4 looked at the two of them with a complicated expression, "Although I don't know what you want to do, I advise you two to dispel this idea, the danger of the outside world is beyond your imagination." ”

"I have a question, has there been no invasion of foreign objects from this place for so many years?" Qian Yunyue looked at the huge gap in front of her, it was indeed a little incredible that there had been no foreign invasion for millions of years.

"Nope." Number 4 shook his head, "I've stayed here and never left, and I've never had an invasion of outside creatures in all these years. The closest thing to go out from this direction is the Giant Beast Continent, but it is also a million kilometers away. Due to the lack of land connection and the distance, even flying beasts can't come here, there was an invasion a long time ago, and it wasn't the beast that took the initiative to attack, but the people who went to explore it for genetic research caught it, but unexpectedly, an accident caused the beast to break through the cage, which led to a tragedy. The natural disaster of that year swept the whole world, and maybe those alien beasts have been extinct in the disaster. ”

"What about sea creatures?" Qian Yunyue walked to the sea, since the sea water is all flowing in from the outside world, it is not surprising that there are creatures entering along the current.

"There is an estimate, but there is basically no exploration of the ocean at present, and the creatures in the sea will not come to the land, so there should be no threat."

Qian Yunyue fell into deep thought, if it was the giant beast world, according to the records he saw in the Starfall Box, there were no intelligent creatures there, which was equivalent to a primordial world. Where there is no civilization and only monsters, it does not have much practical significance for them, and it takes a lot of time to travel millions of kilometers, and this flying car may not last that long.

"With all due respect, the climate at sea is very harsh, and there is no way to reach the Giant Beast Continent with your flying car, unless you have a bigger and stronger vehicle, you should give up." No. 4 just said the question that Qianyunyue was thinking about, "The north and the west are even more impossible, only the southern continent is the closest, but there are very terrifying creatures living there, and this wall is mainly used to resist them." ”

"You mean vampires?" Qian Yunyue suddenly thought, the last time the vampires invaded, why didn't the guardians of the south appear?

"Yes, it's a dangerous creature that transcends common sense, but how do you know? After the wall was built, they probably didn't appear again. ”

Qian Yunyue roughly explained the riot caused by Taiqing Daozun before, and mentioned the matter of the guardian by the way.

"Stupid people, vampires only bring disaster, and it's good that they didn't bring accomplices, otherwise the world would be over." Number 4 has been staying here and is unaware of what is happening in the south. "But it's unimaginable that human power can forcibly break through the energy shield of the wall. And you say the Guardian didn't show up? That's pretty weird, so let me search for it. ”

Qian Yunyue looked at No. 4 with flickering eyes, although she didn't quite understand what she was doing, but according to what she said just now, could she sense the existence of other guardians?

"Guardian No. 2's signal is gone!" No. 4 was shocked, there was a special radio wave induction between the guardians, as long as they were on this Pangea continent, they could find each other's location. "Normally, if something goes wrong in a certain direction, the Guardian will send a signal to others for help when needed, but I haven't received any signals, can I say ......?"

"You try to get in touch with another Guardian." A hypothesis suddenly popped up in Qian Yunyue's mind, could it be Taiqing Dao Zun's doing, if he defeated the Guardian and captured the key, but he didn't know how to use it, so he could only open a crack.

"What's going on? No. 1 and No. 3 are also gone! "No. 4's face changed drastically, what happened?

Qian Yunyue frowned, shouldn't his guess come true, Taiqing Daozun didn't know where to get the news of the guardians, and then found the other three guardians to try to seize the key, the reason why No. 4 was okay was probably because Taiqing Daozun couldn't pass through the woods, so he didn't find her.

After listening to Qian Yunyue's hypothesis, No. 4 was silent for a while before speaking: "The possibility you said is very high, if this is the case, then he may have used the fragments of the key to break through the energy shield, otherwise it is difficult to imagine that the power of human beings can forcibly destroy the enchantment." ”

"What the hell does the key look like?" If this is the case, then you must find Taiqing Daozun as soon as possible, otherwise the fragments of the key will fall into the hands of the vampire, and the consequences will be unimaginable.

"We are the key." No. 4 hesitated for a moment, but finally told Qian Yunyue.

"You're the key?" Qian Yunyue looked at No. 4 in surprise, what does this mean?

"Rather than explaining, it is easier for you to see with your own eyes." No. 4 walked in front of the wall of life, and suddenly a white light appeared all over her body without knowing what she had done, and then she pressed her hands against the wall, only to see that the wall of life also emitted a white light to echo it, and then opened a passage.

Qian Yunyue and the two of them looked at this incredible scene in amazement, it turned out that this was the case.

"Our guardian's body contains a magical ore called meteorite, which can open a passage by interacting with the meteorite inside the wall." Number 4 explained, "So even if it's a fragment of the body, it has the same effect, but the size of the passage changes, and that person probably used the body fragments of another guardian, so only a small crack can be opened. ”

"As long as it's a meteorite?" Qianyunyue looked at No. 4, the Starfall Demon Box was a huge piece of meteorite ore, but it was probably harder to cut a piece from that thing than to ascend to the sky.

"There should be no other meteorite in this world, except for our four guardians, the rest of the ore is used for the construction of the wall."

It turned out that Xingheng Kingdom secretly obtained the Starfall Demon Box built by the meteorite iron mine without telling other countries, Qianyunyue secretly said in her heart, but those don't matter, the top priority is to chase Taiqing Daozun, "Can you help us open the passage?" We must hunt down the man who has fled to the outside world, or the world will be ruined if it drags on too long. ”

"Can I trust you?" No. 4 looked at Qianyunyue and the two of them with a complicated expression, the current situation is indeed not optimistic, if all the previous speculations are true, then I am afraid that it will not be long before the vampires will invade again, with the current situation in this world, I am afraid it will be difficult to resist the invasion.

"Of course, that's why we're looking for the key." Qian Yunyue nodded, they didn't need to fight the vampire head-on, as long as they found the Taiqing Daozun and retrieved the key fragments, the world would be safe.

"I see, I'll open the passage for you, but it's too dangerous to go straight out from the south, it's better to take a detour, and I want to remind you that you can only get back if you get the pieces of the key, otherwise you'll be blocked out of the wall forever."

So the three of them marched towards the southeast of the Desolate Ancient Realm, and on the way, Qianyunyue and the two of them had returned to their peak state by using the Heavenly Clan's mutual transmission technique to cultivate, plus a bunch of modern weapons, there should be no problem in dealing with a Taiqing Daozun. Originally, they had also thought of finding a helper from the Celestial Clan, but the Guardian was still known as little as possible, and this time it was a sneak battle, and it was easy to be exposed if there were too many people.

"After you get out of here, you can see the Dark Night Continent by going in this direction for about 100,000 kilometers." No. 4 didn't know where to take out a backpack and handed it to Qian Yunyue, "There are some equipment I gave you here, use it as much as possible, I have also made some modifications to the flying car, and added invisibility functions." I'd love to go with you, but you're far more powerful than mine, so I'm not going to hold back. It's all up to you, good luck to you. ”

"Thank you for your help, don't worry, we will definitely complete the mission and return smoothly." Qian Yunyue took the backpack, "You just go back and wait for our good news." ”

The equipment sent by No. 4 is really good, first of all, two sets of mimic stealth jumpsuits, which are the ones she wears herself, which can assimilate into the invisible state with the surroundings in various environments, and also have a certain impact resistance.

Then there is a stack of past exploration reports and vampire invasion materials about the Dark Night Continent, people once formed a hundred expeditions to the Dark Night Continent, there were originally many strange beasts in that place, and the vampires were just a group of huge bat monsters, but after they sucked the blood of humans, they turned into human forms, and had quite high intelligence, I have to say that the human form is really quite perfect, this group of bat monsters tasted the sweetness, crazy attack expedition team, and finally only more than ten people escaped back, However, the nightmare is not over, and the humanoid vampire follows with a horde of batakins and unleashes a terrible war of aggression.

At that time, most of the people were civilians, and there was no resistance to the powerful beasts, and in just a few days, hundreds of people died, and the team of vampires grew stronger, and people found that silver metal could cause fatal damage to vampires, which slowly turned the tide. In the end, although the vampires were driven away, the losses were also quite heavy, several cities in the south were destroyed, and the number of dead and wounded exceeded 10,000, but the vampires were also hit hard, and there was no strength to invade again for a long time, which gave people the opportunity to build a wall of life.

The last piece of equipment that Number 4 gave them was two small shotguns and a bunch of silver bullets, which were specially designed to deal with vampires. With this thing, Qian Yunyue and the two of them are more confident, and the next thing is to find Taiqing Daozun and regain the fragments of the key.
