The plan has been set, and everyone has started to bleed, because the smell of blood and blood is not strong enough for one person, and now there are only two days left for aliens, and the mother emperor will not let them out easily, so enough bait is needed.

Generally, blood donation is 200 milliliters, and this amount of blood loss will not affect people's bodies, there are nine people here, and if one person is 200, there will be 1,800 milliliters of blood.

A total of 4,000 milliliters of normal people's blood, 1,800 milliliters is already equivalent to half of a person's blood, so much blood is dumped in one place, the smell of blood is so strong that it can make it difficult for people to breathe, but this is exactly what Ye Yun and they need.

The room they were in was twenty-seven, and the room where the Xenomorph Mother was located was rooms one to fifteen, and there was still a considerable distance from where the Mother Queen was in their place, so they had to walk a long distance forward, and they had to be very careful in the process, because they couldn't be sure if the other Xenomorph would not be in the brood as they had guessed.

Zheng Zha was in front, Ye Yun was behind, and Ye Yun was holding a Barrett anti-materiel sniper rifle in his hand.

Although Barrett's power is at the forefront of the sniper rifle, its recoil is not as great as imagined, because he has a recoil barrel to absorb recoil, and the recoil of each shot is absorbed by the internal barrel recoiling spring, so the recoil is not particularly large, and he is semi-automatic, that is to say, it does not need to pull the bolt to unload after a shot, it can be fired continuously, but you need to shoot a shot and pull the trigger.

The reason why Chu Xuan dared to say that it was enough was because Barrett's power was very amazing, ordinary bullets could penetrate eight millimeters of steel plates in one shot within a range of five hundred meters, and if it was a special armor-piercing projectile, it could penetrate a hardened armor steel plate thirty-four millimeters thick at five hundred meters, and now the power of the metallic bullets in Ye Yun's gun was only stronger than that of armor-piercing bullets, and it was enough to hit the mother.

However, although the power of the bullet is enough, one or two shots may not be able to kill, because the alien body fluids are super corrosive, and the steel plates on the spaceship are all specially made, and the hardness can be imagined, but the blood dripping from the face-hugging worm when one of its legs is cut off in the play can completely corrode the armor within a few seconds, and it has been corroding three decks before stopping, so the bullet may not have really injured the mother queen before it was completely corroded.

Chu Xuan said that five shots were enough for this reason, because he had already deduced from the aliens who had been killed before that Ye Yun's marksmanship should be a little stronger than that of Zero, and he could do both shots in the same position at close range.

Originally, when he held a rifle, Ye Yun could do two shots and one alien, but now he is holding a Barrett sniper rifle in his hand, plus Zheng Zha, the three of them also have rifles in their hands, so although they raised their vigilance to the highest along the way, they ran all the way over.

The physical fitness of the four people was already very strong, the speed of running was already fast, and with Chu Xuan guiding the way, the four of them soon came to the corridor outside room sixteen, but they did not all get together, but Zheng Zhe was in the front, Ye Yun was in the center, and after breaking off with the overlord at zero o'clock, Ye Yun and Zheng Zhe kept a distance of about thirty meters.

Arriving at the predetermined location, Zheng Zha poured out the blood in the bottle without hesitation, and instantly dyed the ground red, and in order to be more realistic, Zheng Zha also forcibly endured the nausea and poured some of the blood on himself, mixed with a little blood from the clothes of the alien who was killed before, and a disgusting smell was born leisurely.

After the blood was poured, everyone tensed up, staring at the intersection in front of them, once they found that the alien rushed out, if there was only one of them, they would not hesitate to turn around and run, if it was two, Ye Yun would try to kill, but he could only shoot two shots.

The time of two shots is the safest time, if once it exceeds two shots and Ye Yun does not kill all the aliens, they are likely to be torn apart by the aliens who rush over, even if they also have weapons, but the speed of the cat aliens is too terrifying.

However, a minute passed, two minutes passed, but there was no reaction in the passage, which made Zheng Zha and them even more worried, because the four newcomers should have been parasitized by now, and if they dragged it down, they would have to face four more aliens, which was a very unfavorable thing, so they couldn't afford to drag it out.

"Is the bait not alluring enough? Shall we add another person? At this moment, Chu Xuan's voice without emotion fluctuated came from the communicator.

Hearing Chu Xuan's words, Zheng Zhe frowned, and said in a low voice: "I don't think it's a matter of whether the bait is enough, it should be that they sense the danger, after all, this thing was specially born for killing, and the perception of danger is still very keen, of course, except for the one that was killed before." ”

At this time, Ye Yun also spoke, and said: "Indeed, the sniper rifle in my hand has the lethality of knowing their fate, and the rifle in Zheng Zha's hand can also cause some damage to them, plus they have already died four aliens, so it is normal to be on guard." ”

Chu Xuan paused for a moment before he said, "You are so vigilant. In this case, Zheng Zha, you should open the arsenal next to you together, there should be some useful weapons in it, if there are heavy weapons, we can go in and kill them directly. ”

Zheng Zha thought for a while and felt that it could only be like this, so Ye Yun and the others also walked up, but just as they were about to open the door of the arsenal, a pitch-black shadow lightning rushed out of the open room fifteen, making the three of them stand on end in an instant.

At the moment of life and death, Zheng Zha felt that everything in front of him had slowed down, he could clearly feel his heartbeat, and a strange feeling enveloped him, and then he instinctively turned around, raised the rifle in his hand to block it, and instinctively raised his right leg and kicked it forward.

He had barely held the rifle in front of him when he felt a super force fall on the rifle in the cross, and then he could clearly feel the rifle in his hand being cut off, but at this time he kicked his right foot into a very hard object.

"Bang!"

With a loud bang, the cat alien who was only more than one meter tall was kicked and knocked into the wall of the passage by him, but he was also hit by a huge reaction force, and was directly knocked into the air, knocking the zero points next to him that didn't have time to react together.

At the moment when Zheng Zha was knocked into the air, Ye Yun "Cai" reacted and quickly raised his gun.

"Bang!" With a crisp gunshot, a huge wound was directly made on the shoulder of the cat alien who had just stood up, and yellow blood splashed onto the floor, and time corroded the floor into potholes, and puffs of smoke rose up almost to block it.

At this time, the overlord also reacted, and raised the rifle in his hand to sweep, and after a burst of fire, the alien completely lost its ability to move, so Ye Yun made up another shot.

However, at this moment, another even bigger black shadow also rushed out, such a close distance, with Ye Yun's current reaction ability, it should not be able to reflect, so he didn't raise his gun.

However, although Ye Yun did not raise the gun, and the overlord's bullets were also used up, and he was in the process of reloading, but Zheng Zha and Zero Point on the other side had already reacted, but Zheng Zha was in front of Zero Point, which just blocked the field of vision.
