"Rats here?" Liu Fan said that he said this on purpose, in order to confuse the hidden island ninja.

Then, with a flick of his right hand, a small sword appeared in his hand, and he pretended not to notice that the other party was there, and then carefully searched around, little by little, to get closer to the black wall.

And the ninja of that island country was more careful, not showing any breath, and not in a hurry, competing with Liu Fan there for patience.

Liu Fan waved his small sword at the air indiscriminately, and his body had already come to the side of the black wall.

"Poof!" Liu Fan's dagger directly cut the neck of the ninja of the island nation.

"You." The island ninja didn't understand why Liu Fan found him, but he never understood.

Liu Fan looked at the fallen ninja, lifted his body, carried it to the room where Xiao Tsuike lived, and put it in the room, "I killed another island ninja, this one looks like a shadow guard ninja, with strong strength, if it weren't for my good eyesight, I'm afraid I would have died." ”

"You're not hurt, are you?" Chen Mengqing said.

"Nope." Liu Fan replied.

"How did you kill him?" Chen Mengqing asked.

Liu Fan said it carefully, "I didn't expect that this island ninja is really good at hiding, this island ninja is more difficult to deal with than I imagined, but the demon is one foot high and one foot high, and it was finally destroyed by us." ”

"These two ninjas of the island country who responded to each other were killed by us, plus the one killed before, a total of three, there are five people on the other side, three appeared, there are two left, and there are people from other countries hiding in the dark, so we have to be more careful, improve security, and I will let the intelligence team come over to deal with this place later." Chen Mengqing said with a cold face.

"Those people are really powerful, we have to be careful." Liu Fan nodded and said.

"Do you remember the mole mentioned by the person pretending to be a doctor before, and the mole mentioned by Xiao Tsuike?" At this time, Chen Mengqing seemed to think of something, and said, "The enemy wants to steal the research technology, and even more wants to destroy here, so there may be a mole hiding here." ”

"What you say makes sense, it seems that we still have to track down the mole." Liu Fan said.

"Now we have killed three ninjas, and we have also found bombs and poison gas before, and we want to take them secretly, but I didn't expect the ninjas to launch an attack that night, I am afraid that this matter has been leaked, the ninjas of the island country know that the explosives and the poison gas have been transported away, plus I killed the three of them, so that they have a lot of losses, maybe they will launch a more crazy attack, what do you think, what are the countermeasures?" Chen Mengqing asked.

"Well, I don't know if the institute can arrange a few days off." Liu Fan asked.

"This can't, I asked Mo Lao, Su Ruoxi, Mo Lao said that the research institute is not only their project in research and development, there are other projects are also in a hurry, and Su Group also has a project here to study, if it is stopped, it will be a huge loss." Liu Fan said helplessly.

"Thousands of people in the research institute commute to and from work, and there are family members who come and go, visit, the situation is very complicated, and it is easy to infiltrate during the day, so it seems that we can only increase the intensity of investigation and prevent the enemy from taking advantage of it." Liu Fan said helplessly.

"This aspect needs to be strengthened, this has been arranged, the new armed police brought a few wolf dogs, people who come in can not come in with explosives and other flammable and explosive materials, all visitors must be from the institute to come out to greet, register for visits, sign a letter of joint responsibility, otherwise, do not come in." Chen Mengqing said.

"Those enemies want to attack, there are poisoning, assassination, network theft, total destruction and other aspects, now, we have changed the security system, with your cousin in charge, this can rest assured, the next is to prevent poisoning, assassination, food, water, express, long-range sniping, air, underground attack, etc., this is too many, it is impossible to prevent it, comprehensive destruction, the other party has not found a way, this can be relieved, however, it is not ruled out."

Liu Fan analyzed in annoyance, and saw Liu Fan's nod of approval, so he continued, "In this way, you stay underground, I will go to the monitoring room to be healthy, and the suspicious person will be investigated by Wu Xiaohong, the captain of the guard team, what do you think?" ”

Chen Mengqing thought for a while and said, "This is feasible, you should be careful yourself, eh, I have discussed it with Mo Lao, such a big thing happened, all the employees participating in the research project are working overtime, and during this time, the food and accommodation are also underground, to minimize the risk of exposure, Mo Lao also agreed, let us rest assured to protect them." ”

"Okay, this can be, in this way, the problem of enemy poisoning can be avoided, there are not many channels for poisoning here, food, water sources, ventilation ducts, etc., the first two can be artificially controlled, and the ventilation ducts are arranged with some infrared detectors, thermal detectors, and it is not so easy to infiltrate." Liu Fan said.

"I have deployed what you said, but the human factor of food and water is very strong, you need to strengthen control outside, and you must pay special attention to prevent the enemy from taking advantage of it." Chen Mengqing said.

"I know that." Liu Fan said.

Then the two discussed the details, and the intelligence team also came over to clean up the place and restore it to normal.

In the evening, Liu Fan sat in the monitoring room, next to Zhang Wanwei and Wu Xiaohong, one was responsible for information and the other was responsible for implementation, which solved many problems for Liu Fan.

Liu Fan moved his gaze to other places, while thinking about the various means that the enemy might use, the research institute re-armed, the intelligence brigade of the mysterious army came to deploy, the monitoring was impermeable, the light and dark surveillance cameras were invincible, and all kinds of high-tech equipment were also used, and it was very difficult to get in.

"Brother, we are tightly armed, and it is difficult for the opponent to infiltrate, right? These are the most tightly armed, it is difficult to get in with wings, and besides, we have cracked the explosives they have arranged, the poison gas bureau, there is no worries, and they do not understand our new armament, the enemy wants to destroy, it is difficult to destroy. Wu Xiaohong said with some emotion.

"We can't take it lightly, we must be serious, we must be careful at all times, if we want to destroy, attack, it's not impossible, it's just that you didn't expect it, the enemy is stronger than we imagined, and it is terrifying." Zhang Wanwei said lightly, her hands kept playing on the keyboard, and all kinds of command characters appeared on the computer screen, dazzling, looking dense, people don't know which ones are which, but they play a variety of roles.
