Time gradually flowed, and before you knew it, the day passed, and the night fell.

Liu Fan didn't dare to relax for a moment, since he knew that the people of the Viper Mercenary Group were in Huadu, Liu Fan was full of vigilance, he knew that the people of the Viper Mercenary Group were very terrifying, just like poisonous snakes, you don't know when he would appear and launch a deadly attack on people.

The night is getting darker and darker, this is a metropolis, and the lights are bright all around, but this research institute is in the middle of nowhere, and the lights here are not very bright, but the surroundings are not dark.

Liu Fan carefully observed the surroundings, suddenly, he saw a figure passing by, this look, I think it may be dazzling, but Liu Fan doesn't think it's dazzling, he believes in his eyesight, and he has also been trained in related aspects, he knows that it is a person, but the speed of that person is very fast, so fast that people feel dazzled.

Liu Fan was immediately vigilant, he didn't know if it was a member of the Viper Mercenary Group, in short, he had to be careful.

He picked up his pistol and walked over there.

"Bang bang!" At this moment, one or three or four gunshots rang out outside the wall.

Hearing the gunshot, Liu Fan was shocked, and hurriedly arranged for the captain of the guard team to patrol to prevent outsiders from easily mixing in, while he ran outside the wall.

At this moment, he suddenly saw a figure, only to see that this figure was very familiar, he thought about it, and found that this figure was more and more like a person, and then fused from his mind, and suddenly, a person appeared, Chen Mengqing.

"She's coming?" Liu Fan secretly said in his heart, he didn't know if it was Chen Mengqing, he quickly chased after it, and found that there seemed to be a tree in front of him, which was a tree planted on the street, carefully hidden.

"Who?" At this time, Liu Fan suddenly found that a figure appeared behind him, silently, very well hidden, hearing this figure, Liu Fan was overjoyed, this time, he was more sure of his guess, this is Chen Mengqing.

"My own person, Mengqing, it's me, Liu Fan." Liu Fan hurriedly said.

"Is it really you?" Chen Mengqing was happy in her heart, she didn't expect that she had found Liu Fan, she also thought that Liu Fan had been killed by the people of the Viper Mercenary Group.

"It's me." Liu Fan said, "I heard a gunshot just now, did you shoot it?" ”

"I fired one shot, the other side fired three shots, and if I'm right, the other party is a member of the Viper Mercenary Group, and two people." Chen Mengqing said, her body is extraordinary, just now I saw that it was a person from the two poisonous snake mercenary groups, "However, the other party is very cunning, and good at hiding, it is very likely to be a hidden snake, this hidden snake is very good at disguise, and is also good at makeup, I don't know when it will be made up into the person next to you, so you must be careful." ”

"Yes." Liu Fan nodded, he was very happy to meet Chen Mengqing here.

"Are you on a mission?" Chen Mengqing looked at Liu Fan and asked.

"Yes, my mission is confidential, I can't ......" Liu Fan's face showed embarrassment, he knew discipline, and the task should be kept secret, so he couldn't say it easily.

"I know that you are on a security mission to protect Mo Qichen and the achievements of artificial intelligence technology." Chen Mengqing said.

"How do you know?" Liu Fan had a look of surprise on his face.

"Don't forget that I'm from the mysterious force, and the mysterious force is well-informed, and the people in the police station know that there are mercenaries in Huadu, coupled with their style, the mysterious force speculates that it is a poisonous snake mercenary group, and I also asked my cousin Captain, so, knowing your security mission, don't be surprised, I also took this task." Chen Mengqing looked at the surprised Liu Fan and said, "Now, when we don't talk about this, we have to kill that hidden snake, and after that, we are carefully talking about the mission." ”

"Okay." Liu Fan nodded, regaining his composure, he also knew that the top priority now was to find out the people of the Viper Mercenary Group and prevent them from invading the research institute and causing losses.

"I noticed that they seem to be heading for the guards, I don't know if they are hiding in the guards, you are trying to force them out." Chen Mengqing said.

"That's fine." Liu Fan said, he thought about it, and decided to let the people of the guard team run and make them sweat, the people of the Viper Mercenary Group have tattoos, as long as they find their tattoos, they can attack them.

Soon, the guard team of the research institute was running quickly, constantly protecting, and after about half an hour, everyone was sweating profusely, and a lot of makeup powder began to fall off.

Liu Fan's eyes were staring closely, and at this moment, suddenly, he saw a faint tattoo on a person's neck, and then, it gradually became clear, and a poisonous snake sting came to life.

"Discover one." Liu Fan took out his pistol without hesitation, and then shot the man's leg instantly.

With the sound of "bang", the person was knocked down, and everyone didn't understand what was going on, and Wu Xiaohong, the captain of the guards, also ran over and looked at Liu Fan in confusion, "Liu Fan, what's wrong?" ”

"Get out of the way." Liu Fan shouted.

Suddenly, the person who was hit flew up instantly, holding a sharp dagger in his hand and launching a fierce attack on Wu Xiaohong.

"Bang!" At this time, Liu Fan picked up the pistol and hit the man's arm, and the dagger in the man's hand fell off, making it difficult to attack again.

Liu Fan came to the front of the man and crushed his ribs with one kick, "Ah" The man let out a miserable scream, it was difficult to attack, Liu Fan took a closer look at his neck, and found that it was really a member of the Viper Mercenary Group.

"It's dangerous." Wu Xiaohong was very glad in his heart, if it wasn't for Liu Fan just now, I'm afraid he would die, he didn't expect this death to be so close to him.

"Captain Wu, he is the murderer who came to cause sabotage, come over a few people, arrest him, and guard him." Liu Fan said to Wu Xiaohong.

"Understood." Wu Xiaohong believed in Liu Fan's words, and he knew that Liu Fan was protecting them.

"You two, come here." Wu Xiaohong said to the two guards next to him, and soon four or five guards came over.

"Carry him away." Wu Xiaohong said.

The two guards walked over to pick up the wounded Viper mercenary group.

One of the guards walked over to Liu Fan, "You're blocking my way." ”

"Huh?" Liu Fan was slightly stunned, he didn't understand why this guard said this, isn't there a road over there? However, in the next moment, he suddenly felt a huge aura of danger, and the guard took out a pistol in his hand and shot at Liu Fan instantly.

"Not good." Liu Fan hurriedly dodged.

"Bang!" A gunshot rang out, grazing Liu Fan's shoulder and erasing a bloodstain.

"Bang!" At this moment, a gunshot also rang out instantly, hitting the guard's eyebrows, and the red and white objects flew and fell to the ground.

Liu Fan hurriedly squatted down and checked the person, and found that there was a lifelike snake tattoo on his neck, this was a member of the Viper Mercenary Group, and judging by his makeup and hiding ability, then this person might be a hidden snake.

"What's wrong?" At this time, Chen Mengqing walked over, holding a pistol in his hand, and asked Liu Fan.
