At this time, Wang Fatzi slowly pulled out the Tang knife from his waist, looked at everyone contemptuously, he didn't like to talk much, and slowly spit out a few words: "You guys, do you want to go together?" ”

A group of people looked at the Tang knife in Wang Fatzi's hand, they were a little timid, at this moment, at the exit of the alley, a strange beast ran out, listening to everyone's voice, rushed over like a gust of wind, Lu Xuan hurriedly pulled Qu Zijing to the side, Wang Fatzi also quickly dodged, and the others let out a terrible scream after seeing the strange beast.

The alien beast listened to the sound and entered the crowd, and in an instant, he ended the lives of two people with his front paws, and the others immediately scattered and fled, and the alien beast chased after killing four people, only Lu Xuan and the three of them who were hiding by the wall were ignored by the alien beast, and after waiting for the alien beast to disappear completely, Lu Xuan and the three of them did not dare to stay, and hurriedly walked out and walked in the opposite direction. I heard heart-rending screams in the distance, but soon there was no sound. Lu Xuan knew that the few people who came out just now had all been killed by the alien beasts.

Wang Fatzi put the Tang knife in his hand into the scabbard and shook his head. Lu Xuan pulled Qu Zijing and walked in the direction of his memory, the three of them killed several strange beasts along the way, and successfully came to the door of a supermarket, the windows and glass doors of the supermarket were intact, and a thick layer of ash fell on them, obviously no one had visited for a long time.

The three of them pushed open the door of the supermarket and walked in, the items inside were neatly arranged, still the same as before the disaster, the three of them took off their backpacks and began to search for the supplies inside, all the food that could provide high-calorie food was their priority to collect, and soon the backpacks of the three people were full. Wang Fatzi also took out a bottle of red wine in the wine cabinet, sat on the cash register, and drank energetically. Just as the three of them were about to leave, they suddenly heard a burst of gunfire outside, accompanied by the sound of running, from far to near.

Lu Xuan scolded secretly, the three of them hurriedly walked to the door to watch, the two soldiers in the distance turned around and shot while running, behind the two of them there were four strange beasts that were rapidly approaching, according to the speed of both sides, they couldn't wait for the two soldiers to run to the supermarket and would be chased by the strange beasts, but the two of them could not escape death, seeing this Lu Xuan put his mind at ease, now in this year, as long as it does not endanger his own affairs, try not to care, otherwise it is likely to harm himself. When the two saw Lu Xuan in the supermarket, they hurriedly waved their hands and shouted, obviously wanting Lu Xuan to help.

Just when Lu Xuan just wanted to turn around and leave, he found that the two soldiers who came over looked very familiar, they turned out to be Tian Hao and Sun Qiang, since they were acquaintances, there was no reason not to help. After all, there are only four strange beasts, and Lu Xuan and Wang Fatzi don't care about it at all. Lu Xuan took the compound bow from behind him, beckoned the fat man and walked out, bent the bow and took the arrow, and shot an arrow with a little aim, and the feather arrow went straight to the two, and the two who were running over were startled, and wanted to bow their heads but it was too late, only to see the feather arrow pass through between the two, directly killing the fastest beast. Qu Zijing's archery technique was not as good as Lu Xuan's, so he naturally didn't dare to do so, so he turned his body slightly and shot an arrow, but it only hit the body of a strange beast.

With two arrows to cover the two, the two finally rushed to the door of the supermarket, and hurriedly turned around to shoot, Lu Xuan grabbed the two and said, "Don't shoot, this will only attract more strange beasts." Before the words fell, a few strange beast king fat men appeared from the side, stepped forward, drew their knives, slashed and slashed a strange beast that leaped up, Lu Xuan also shot an arrow with his bow half-opened, although the strength was not enough, it still pierced the chest of the strange beast. Qu Zijing calmly pulled his bow and released his arrows, and under several rounds of attacks by the three of them, only one or two strange beasts ran to the front but were all killed by Wang Fatzi one by one.

The two people standing behind them all looked at the three people in front of them with a kind of monster-looking eyes, and the nine strange beasts were killed by the three of them so lightly, and the expressions of the three people were not flustered at all, as if they were breathing. At this time, Lu Xuan also turned his head, looked at the two of them with a smile on his face, stretched out a hand and said, "Long time no see, Company Commander Tian." ”

The two of them who survived the catastrophe settled down to look at this familiar face, and they couldn't remember who it was for a while: "I saw that Company Commander Tian had forgotten me, let's go, let's go in first, it's still very dangerous outside." After saying that, the five of them returned to the supermarket, and after Lu Xuan's reminder, Company Commander Tian remembered:

"It turned out to be you. I really didn't expect that we would meet one day. ”

"Yes, last time I said goodbye, you went to reconnoitre, I thought you would die inside."

"Hey, don't mention it, we almost died in it last time. Later, we met another team, the reconnaissance company of the Lizhou Military Region, and we explored it together, and when we could already see the source from a distance, we were discovered by a strange beast, and we were fiercely besieged, and just when we thought we were about to die, several planes flew in the distance. ”

"Airplanes? Where did the plane come from? Lu Xuan and the others were very surprised, because they knew that the Lizhou Military Region no longer had any air power.

"We didn't know that at the same time as the plane appeared, all the beasts on the ground looked up at the plane in the sky, and they didn't continue to attack us, so we took advantage of this gap to quickly run out and find a place to hide. Just as we were taking cover, we heard several explosions in the sky, and all the planes that flew by were knocked down. But we've already hid it all, and the beasts searched for a while before they found us, and we all slowly dispersed. ”

"The plane crashed? Attacked? Lu Xuan was a little puzzled, planes are generally at an altitude of several thousand meters, and this is a fighter jet, how can that speed be caught up by ordinary things, it can actually shoot down planes, these strange beasts seem to have the ability to fight in the air.

"I don't know, we didn't see it clearly, we were in a hurry to find cover, and we didn't pay attention at all. But we saw that as soon as the ejected pilot opened the parachute, a cloud of blood exploded in the sky, and none of them fell to the ground alive. ”

"If it's an attack, which black ball should do it?" Sun Qiang said his guess next to him.

"Black balls? What black balls? Lu Xuan felt that his brain was running out of money.

"Oh, that's right, there's nothing secret or secret now, as long as it's alive, it's your own. After we investigated, we now see that the alien beasts are only the lowest alien beasts, and these alien beasts are huge in number, but don't you feel very strange, these alien beasts are like they can't be killed, and it won't be long before another one comes over to take its place. ”

"That's right, I've been aware of this question for a long time, but I can't figure out why?" Lu Xuan faintly felt that he was about to reach a critical point, and he couldn't help but feel refreshed.

"This is the key, we found a black ball, from time to time there will be strange beasts running out of it, there is no fixed time, according to our observation, there should be a strange beast when he dies he will come out of the corresponding strange beast to replenish, because these foreign beasts are going in different directions, but just a while ago, we found a very large foreign beast raid, a large number of foreign beasts continue to rush out of it, and soon it is not only the most basic foreign beast, like a snake, There was a big beetle, and a few flying beasts came out at the end, but they just came out and didn't fly far before they came back and disappeared into the black ball. ”

"Lizhou base." Lu Xuan said.

"You know? That's right, it's the Lizhou base; Later, I learned that when the black ball kept spewing out strange beasts, it was when the strange beasts in the Lizhou base attacked the city. Company Commander Tian was a little surprised, and Lu Xuan actually knew about the Lizhou base.

"We were there when the alien beasts attacked the city at the Lizhou base. After the siege was over, we left. Lu Xuan explained.

"Huh? When we arrived at the Lizhou base, it was in a state of freshly attacked city, and it seems that we didn't have a long time to go. Also, otherwise we wouldn't have met here and wouldn't have been saved by you. Haha, it seems that my Lao Tian should not die. Company Commander Tian said with a hearty smile.

"That's a coincidence, we've just arrived here, and we're about to leave after the supplies, so we're going to run into you, if you're a little late, we'll leave." Lu Xuan also felt that this world was really quite small, otherwise it would not be so coincidental. Lu Xuan was more interested in the black ball that Lian Chang Tian said at this time, so he asked directly:

"What do you mean by black ball?"

Sun Qiang frowned and thought for a while, as if he had confirmed it, and then said: "It's not completely black, it has a diameter of more than a hundred meters, and there is something circulating on it, it feels like a liquid, and those strange beasts all jump out of it directly and fly out, and it's the same when you go back; ”

"That's not a black ball, it's a wormhole." Lu Xuan's face became extremely ugly, the last thing he wanted was this.

Qu Zi asked puzzledly, "Wormhole?" Shouldn't a wormhole be a hole? Why is it a ball? The rest of the people all looked at Lu Xuan with curiosity. Lu Xuan took out a pen and a blank piece of paper from under the cash register and explained it to everyone.

"Look, I have a blank sheet of paper in my hand, if we want to move here from here." Saying that, Lu Xuan drew two circles on both ends of the white paper, "We feel that the shortest distance is a straight line. Lu Xuan drew a straight line between the two circles and linked them, "But if I feel that it is still too far, I will do it." Saying that, Lu Xuan bent the paper up, overlapped the two circles together, and then stabbed the pen in his hand into it, "Do you think the distance is so short, or is the straight-line distance just now short?" Obviously, it's shorter, because the paper is a two-dimensional plane, so it can only go in a straight line, but we now use a three-dimensional method to bring the two points closer together, which is a hole, and you can go to the other side by walking from this side; It's a hole in the paper of two-dimensional space, what if we turn two-dimensional space into three-dimensional space. ”

Lu Xuan glanced at everyone and found that everyone was listening attentively: "Then this hole will become a spherical hole, so these holes are the products of extraterrestrial civilizations, the other side of the black hole should be a more advanced civilization than us, our human beings on the earth have only mastered the three-dimensional space, if I guess correctly, the other party should have mastered the existence of at least the five-dimensional space civilization." ”
