What was that like? What happened to the position that could cause Shen Yan and Guan Feng's eyes to focus?

The mouse is still a mouse, but in the eyes of the two of them, the new mouse is very large, the size of an unmutated domestic cat, and it is not one.

Guan Feng opened his mouth as if he wanted to say something, but Shen Yan directly took out the machine gun as if he knew, and spewed out tongues of fire. More than a dozen huge mutant rats seemed to be extremely intelligent, and as soon as Shen Yan's movements started, they were already moving rapidly, and the sharp slope roof of the villa seemed to have no obstacle to them, as if they were walking on the ground.

The locking effect of the bioradar showed its power at this moment, and the reflexes of the strengthened body also showed its strength at this moment, Shen Yan moved with the machine gun as those giant rats moved, and pieces of blood splashed from the bodies of those giant rats, and a tragic squeak came out of the mouth of the giant rats. But the power of the bullet only made them pause for a moment, but did not completely kill them. Even in the process of Shen Yan's frantic strafing, they reacted extremely quickly, and more than a dozen figures directly dispersed, making it impossible for Shen Yan to cause damage to them at the same time.

"Concentrate your firepower and don't let them break through!" More than a dozen mutant giant rats spread out, and they actually walked along the edge of the roof towards Shen Yan's back, seeing this, he locked on a giant rat and strafed it, while shouting loudly to the soldiers behind him.

Although the soldiers didn't have Shen Yan's reaction, it was enough for them to feel the crisis coming, dozens of tongues of fire erupted under Shen Yan's loud shout, but the speed of the giant rat was too fast, and the reaction of ordinary people couldn't keep up with their speed at all. And they were too scattered in the blink of an eye, which made it difficult for the soldiers to concentrate their firepower under the cover of night.

The first scream sounded behind Shen Yan, followed by the second and third...... One after another, the night sky was filled with horror.

"Captain, the protection experts go first, we can't stay here any longer!" Eventually, the bullets in the machine gun missed, and the result was the death of seven giant rats, and at the same time, he also obtained 100 points of star energy from each giant rat, according to the conversion of star energy, each giant rat level is level three.

The appearance of the mutant giant rat made Shen Yan clearly realize that the hope of protecting all the soldiers behind him had come to naught, and now the only choice was to let the important people retreat first. For he knew that the lives of these men were greater than all men, and even of all of them, including himself, if in the general sense. After all, they can only fight at most, but they may develop a serum that resists the virus, and it is possible to develop an enhancement liquid that strengthens the body, which is a great blessing for all survivors.

As for these soldiers at the moment, they have been given a mission since they accepted this escort mission, and they are in a dilemma of life and death, and Shen Yan can't control whether to continue to carry out this mission, and he thinks that he does not have the righteous spirit of sacrificing his life for righteousness.

"Mom, you have to hold on, we'll be able to get out of here soon!" Not far behind her, Zhang Shanshan hugged a woman and cried, the slow speed of the team in front of her entering the building, so that even if she could see the window of hope that represented survival, she could not move forward half a step.

"Compress the line of defense and concentrate the firepower!" Shen Yan and Guan Feng were no longer alone in the rear, but directly rushed into the second villa on the left, which was where the three biological experts were standing, and they were also waiting, waiting to cross the rope to the opposite building!

At the moment, there were less than sixty people on the roof, and only thirty people entered the building, half of the sixty, and a ring of defense lines was established on both sides of the roof and behind the house. All the soldiers had limited vision and could only shoot constantly, allowing the bullets to form a protective net to stop the rat swarm. There are not many mutant rats on both sides of the roof, but there are seven or eight mutant giant rats here, threatening the defense line at all times. The most stressful is on the right, the mutant rat that rushed out of the villa that first changed, and now the entire roof of the three-frozen villa is almost completely covered by them.

Zhang Shanshan's mother is a beautiful woman with a lean short hair, her whole face is a little pale, when Shen Yan came here, the other party was sitting on the roof, Zhang Shanshan knelt beside her and cried. There was also fear on her face, but more kindness, stroking Zhang Shanshan's hair to comfort and encourage. Several soldiers guarded the mother and daughter, and Cheng Yanqiu was also here, but she did not command the battle, and it was Li Shanguo who really commanded.

"Why is it so slow?" Shen Yan came to Cheng Yanqiu's side in a few steps and asked loudly.

According to Shen Yan's idea, with the aid of a rope and a distance of three meters wide, these soldiers should be able to pass quickly, but until now, almost ten minutes have passed, and many people have died, but not many people have entered the building, which makes him have to be anxious. Even after the question, he didn't wait for the other party to answer, and rushed forward a few steps to the edge of the far left.

The ropes that had been tied earlier were still there, and not only that, but there were even a few more ropes next to and above them, and the top of the ropes was artificially laid with wooden planks, like a slope-shaped pontoon bridge in the air. Unfortunately, there was no one on the pontoon bridge because it was not yet fully laid.

"Made, what are you doing, eh, can anyone tell me what they're doing?" Shen Yan hurriedly came to Cheng Yanqiu's side, grabbed the other party's collar and asked in a deep voice. It was evident that after a few minutes of delay, many soldiers had died to erect the pontoon bridge, as if to make it easier for someone to pass through.

Just when Shen Yan's eyes looked at Zhang Shanshan's mother and daughter beside Cheng Yanqiu, Cheng Yanqiu really said his guess: "They can't get by, Aunt Qi's body is not ......"

"Can't get through? If you can't get by, don't get by! It was hard for Shen Yan to imagine that the other party would let the soldiers sacrifice for the sake of two people, it was hard to imagine what Cheng Yanqiu's mind was thinking? He roared in a deep voice: "Li Shanguo, let everyone shrink the defense line back and strengthen the firepower!" ”

Li Shanguo was directing the battle not far away, and the battle during the day consumed a lot of ammunition, although the vehicles carrying supplies were more than 100 meters away, but the distance of more than 100 meters was all surrounded by mutant beasts, and there was no chance to snatch it at all. So now in the hands of the soldiers in the defense line on the roof, it is a collection of ammunition in the hands of all the soldiers, and each person has less than three magazines.

The order to erect the air pontoon bridge was given by Cheng Yanqiu, and the order of the chief officer Li Shanguo had to be carried out. The three experts were all old men over half a hundred years old, and the soldiers who were more than three meters wide might be able to climb over, but they couldn't, and even the general's wife and his daughter, whose weak bodies were impossible. And the rope that Shen Yan arranged before was too simple, it was basically just a point of borrowing, which made it difficult for the soldiers to carry their past thoughts and carry them.

In desperation, Cheng Yanqiu issued such an order, and Li Shanguo also carried out this order. According to their ideas, it is not difficult to erect a pontoon bridge, just add a few more ropes and lay a few planks and everything will be done. But who would have thought that the attack of the mutant rat swarm would be so fierce that their activity space would be compressed to a corner in such a short time.

When Zhang Shanshan heard what Shen Yan said, she suddenly rose up and asked loudly: "What did you just say, you dare to leave my mother here?" Believe it or not, I killed you! ”

Zhang Shanshan's mother's name is Qi Lan, this beautiful woman raised her weak arm and wanted to stop Zhang Shanshan, but the arm she had just raised was finally weakly put down, and she could only say weakly: "Shanshan, don't ...... Don't do this! ”

From Shen Yan rushing in here to questioning Cheng Yanqiu, the whole process took less than a minute, and seeing that things had become like this, he didn't bother to shout, and said directly to Guan Feng: "Captain, you go over first, and the middle side responds!" ”

Guan Feng glanced at Shen Yan, nodded and strode a few steps to the edge, grabbed the waist-high new cloth rope, and then swung to the wooden board in the center of the pontoon, and the pontoon shook but quickly stabilized, it can be seen that the pontoon bridge is being erected quite smoothly!

Shen Yan came to the three experts, and couldn't help but push them forward, and when they reached the edge of the roof, he grabbed the arm of one of the experts and threw it away, and the latter went straight to Guan Feng to "fly", and that arm was powerful. And Guan Feng was also quick-eyed, grabbed the expert who was thrown over by Shen Yan, pulled it loose, and threw it to the window with Shen Yan's strength. As for the side in front of the window, there were already two soldiers in front of them, but they had sent the dismantled wooden planks from the room they were in before, but now they were bringing in the people who had been sent by Guan Feng.

It only took less than twenty seconds for the three experts to pass, and after they passed, Shen Yan came to Zhang Shanshan in a few steps and grabbed Qi Lan, but his hand was hugged by Zhang Shanshan fiercely, and he asked: "What do you want to do, my mother is sick, and if you do this, it will kill her!" ”

"Shanshan, don't, let him ......" Qi Lan only said a few words, his whole face turned a little pale, and he couldn't even speak.

Shen Yan glanced at Zhang Shanshan in disgust, broke free and pushed him, grabbed Qi Lan's arm directly, and reached into the other party's leg to hug him. He knew in his heart that these people had to be sent over first because of their identity, otherwise, Cheng Yanqiu and they would definitely not give in, after all, this was the task of their trip, otherwise they would not have erected any pontoon bridges for these people.

A few steps to the edge of the pontoon, Shen Yan directly threw Qi Lan out so flatly, it seemed to be rough but the strength was used very well, and there was not much bump, and although Guan Feng did not hold it with both hands, he also sent it extremely smoothly with one hand, and sent Qi Lan to the two soldiers in front of the window, and the whole process was smooth without a little wave. At this time, Zhang Shanshan had already rushed in front of Shen Yan in a few steps, but before she could speak, the latter grabbed her arm and shook it suddenly.

Shen Yan threw Zhang Shanshan at Guan Feng, and shouted loudly without turning his head back to the defending soldiers: "Hurry, the others are faster!" ”

A scream came out of Zhang Shanshan's mouth, and the moment she was thrown out by Shen Yan, she felt as if her whole person had flown up, and in the process of flying, she only felt that her arm flew out again until she settled.

After being caught by the two soldiers at the window, Zhang Shanshan looked at Shen Yan's back on the opposite roof viciously, and screamed loudly: "Shen Yan, if you wait for me, I will definitely kill you!" Do you know who I am? I'm a messenger ......"
