"What are the ways?" Liu Fan asked, thinking that maybe the enemy really found a way.

"Here, you see, they're attacking." Zhang Wanwei's face turned grim, and she suddenly pointed to a place displayed on the screen and said.

Liu Fan leaned over to take a look, and found that a small fly was displayed on the screen, a little far away, buzzing in the air, as if he had thought of something, his face couldn't help but change, Wu Xiaohong couldn't see anything famous, and asked in surprise, "Where is it?" ”

"This is a big city, have you ever seen a fly fly so high above the city? And fly so steadily? Liu Fan reminded angrily, "This may be a fly, a tool used for reconnaissance, I really didn't expect these people to even use flies, they made mechanical flies, and their defense was clearly seen by them." ”

"What should I do?" Wu Xiaohong asked in surprise.

"You don't have to look at me, you can figure it out for yourself." Zhang Wanwei smiled and looked at Liu Fan.

Liu Fan pondered for a while, and said, "We don't have to care about it, flies are flies, just let him fly, if you come over, shoot it to death, we can do whatever we want, and then we will change the deployment at night, so that they are unpredictable, we have a lot of people, in front of the big defensive force, the enemy does not dare to come hard, will only sneak, yesterday and today we were not successful, and today our defense force has increased, the enemy is more difficult to succeed, we carefully check, make good arrangements, and crack all the enemy's destruction." ”

Although he said this, there was a faint uneasiness in his heart, he didn't know what was going on, he sensed that there might be danger, or that the enemy might attack, and there was no reason for this.

Liu Fan took a few deep breaths, calmed himself down, and continued to monitor the research institute.

Time flickered, the sky became dark, night fell, Liu Fan got in touch with Chen Mengqing and others underground through headphones, and after making sure that everyone was fine, he was relieved a lot, but he didn't dare to be careless, and the uneasiness in his mind gradually became stronger, and he always felt that there was a dangerous atmosphere, such a passive defense method made Liu Fan feel very aggrieved, but he didn't seem to find a better way to fight, and he could only defend like this.

After about ten o'clock, Liu Fan saw that the lights outside would be bright, the neon lights were flashing, the cars were coming and going, the sky was dark, and he couldn't see the shadow of the moon or the stars, and the leaves outside the window were blown by the wind, as if there was something in the night, but Liu Fan's mood was difficult to calm down, and the uneasiness in his mind became more and more difficult, and the dangerous breath seemed to be gradually approaching.

He thought for a while, gritted his teeth, and after discussing with Chen Mengqing through the headphones, he issued an order to let all the guards retreat to the wall to hide, give up the outer defense, and arrange twenty people to guard the gate, and the entire research institute entered a state of alert to prevent a fly from flying in.

And the people in the research institute have long known that the research institute is in danger, and they have nothing to do at home and do not go out, do not go out easily, do not meet friends, those who do not work overtime are off work, no one is allowed to enter the gate, everyone is loaded with bullets, and they are ready to fight.

At this time, the night is getting closer and closer, although the outside looks brightly lit and lively, but inside the research institute is very quiet, unusually quiet, as if something is always going to happen.

The wind was blowing gently, and in the wind, it seemed as if something unusual was happening at any time.

"Boom!" At this moment, a huge explosion sounded, in this quiet night, it seemed very abrupt and loud, Liu Fan checked the monitoring, found nothing abnormal, couldn't help but look at Zhang Wanwei, thinking that the monitoring was controlled again, Zhang Wanwei shook her head, Liu Fan looked at Wu Xiaohong.

Wu Xiaohong heard the gunshot, his face changed greatly, he rushed to the window, looked at the explosion outside, and said, "It was an explosion in the direction of the workers, and the situation is not very clear." ”

"Wait." Liu Fan came to the window to take a look, the smoke was billowing in the distance, the fire was soaring, the destructive power of the explosion was very large, it was obviously a powerful explosive explosion, his face was cold, his eyes were slightly condensed, and he said, "That's a big explosion, the enemy is a plan to divert the tiger from the mountain, we can't move, we must guard to the death, do not let the enemy get close to the office building, and infiltrate the underground space." ”

Liu Fan remembered the last time he went to the Su Group to protect Su Ruoxi, last time he was the second shareholder of the Su Group, and the third shareholder competed for shares, Liu Fan stepped in to help, so that the people of the Viper Mercenary Group had a chance to rush into the research institute, he hurried back to the research institute, but fortunately, Chen Mengqing arrived and solved the hidden snake of the Viper mercenary group with him.

Now, it seems that the same thing is happening, but this time the enemy is a member of the Viper Mercenary Group, or an islander, or someone else, so it's hard to say.

Therefore, we need to be careful, only in this way can we protect the people of the institute and protect the research results of the institute.

"No, what will happen to this explosion?" Wu Xiaohong asked, with an anxious look on his face.

"Arrange for the deputy to go over, you don't have to go over, stay here to assist me, you tell everyone that you are not allowed to go near the office building, otherwise, you will be killed, and no one is allowed to go now." Liu Fan said calmly, his face was cold, there was no doubt, his eyes looked firmly ahead, his expression was firm, his eyes were restrained, and he thought about it, the enemy seemed to want to launch a new round of attacks, no matter what, they could not succeed.

"Is this someone deliberately creating chaos, and then trying to fish in troubled waters, and there is an opportunity?" Wu Xiaohong also reacted, as soon as the explosion came out, people panicked, they would approach outside, they would unconsciously approach the office building, and at that time, the enemy might be in the crowd, and then they would mix into the office building, and then they would want to take the opportunity to blend into the underground, and when the time came, it might be troublesome, as soon as he thought of this, Wu Xiaohong couldn't help but feel excited, the enemy was so cunning, and all means were used, so he quickly agreed, made a call, and asked the deputy to put out the fire.

Zhang Wanwei saw that Liu Fan responded calmly, did not panic at all, was not panicked, very calm, not at all like some people, once there was an explosion, he would lead people to rush out, losing the overall situation, she couldn't help but smile and said, "You are calm, what if the enemy runs away?" ”

"Run, run, run, nothing, this enemy can't be caught, and my task is to protect this place, as long as I protect this place, my mission will be successful." Liu Fan said calmly, his firm eyes were calm and calm, and there was an angry look, the enemy was too arrogant, and he actually made an explosion in the middle of the night, as a soldier, this is a shame, a shame that cannot be tolerated.

However, he will not let the enemy succeed, he will protect the research institute, he will not let the enemy's purpose succeed, he will crack any of the enemy's means, prevent the enemy from entering the office building, and cause great damage.
