The space in the ventilation pipe is small, although Zhao Jianfei can see the following situation through the air outlet. But Loren was outside the range he could aim, and the space was too narrow for Zhao Jianfei's automatic rifle to point at Loren because there was no angle. Besides, it is taboo to shoot in such a pipe, and a few shots will deafen your ears.

Zhao Jianfei moved his body slightly, curling himself tighter. So that when you kick the inner wall of the ventilation duct, the body can suddenly stretch out. He was ready to burst out of the ceiling vents.

The Red Baron, who was chatting with Loren below, suddenly moved his eyes and narrowed slightly. In an instant, he suddenly pressed Loren. Rolled on the spot and hid behind a black bodyguard. Almost at the same time, Zhao Jianfei burst out of the vent in the ceiling, and the person was still in the air, and the automatic weapon in his hand began to spew flames.

"Da Da Da ......" The Red Baron rolled over to avoid the shot, and pushed Loren into a shooting corner. Turning his head to look again, the tall bodyguard behind him had been shot several times, and he fell down unwillingly.

The Red Baron rolled on the spot, picked up the bodyguard's gun that had fallen on the ground, and dodged as he returned fire. Black Pearl Betty, but took the opportunity to pull Loren into the dining room suite on the side.

The two men reacted extremely sharply, when the guards began to react and led the group to rush in. The Red Baron and Betty have succeeded in keeping Loren out of the danger zone.

"What's going on?" growled Loren.

"Enemy attack! Get your men ready, they're already in this building. The Red Baron snapped. "If you want to live, do as I say!"

Loren looked at him in surprise and said, "How do you know there's someone in the ventilation duct?"

"I smell gun oil. CLP maintenance oil has a very special taste when it volatilizes. The Red Baron sneered, "I probably know who the other party is!"

He shouted through the door, "Gemini, I didn't expect us to meet again so soon." How's it going?"

Zhao Jianfei didn't answer him, but raised his hand and shot a barrage of bullets, forcing the red baron to hide in the corner again. But at this time, the guards outside also rushed in, but when he rushed in, they fell to the ground one after another. Because Lin Rui followed behind them, the automatic rifle in his hand fired a round of strafing. The group of guards only heard the gunshots, so they ran into the room, but they didn't expect that there would be people in the corridor behind them, and they were shot and fell.

Lin Rui took the opportunity to step into the room and stood with Zhao Jianfei, "Boss, where is the goal?"

"I was spotted by the Red Baron before I could shoot. He brought Loren into that room!" Zhao Jianfei changed into a magazine, strode over and kicked the door open, then quickly dodged to the side. Sure enough, as soon as the door was kicked open, the Red Baron opened fire outside. "Bang bang!" is the sound of two pistols.

The bullet almost grazed Zhao Jianfei's nose and flew over, shocking a master like Zhao Jianfei into a cold sweat. The Red Baron is really not an ordinary person, and in such a situation, he can still maintain enough calm. After the two shots missed, the red baron did not shoot blindly, but calmly withdrew the gun, and confronted Lin Rui and Zhao Jianfei in the room and outside the room.

The timing was in their favor, as long as it dragged on for one more minute, a large number of guards below would rush up, and Zhao Jianfei and Lin Rui would not be able to escape.

So the red baron was not in a hurry at all, and played with the gun in his hand, "You are not small, even I have to admire you, you really dare to enter Longtan alone." However, Zhao Jianfei, you and I both understand that if you missed the blow just now, you have lost all the initiative. Now that the shape shì is in our favor, Loren's guard will soon arrive. ”

Zhao Jianfei's body was leaning against the wall, poking his head out slightly, and there was a burst of strafing. The Red Baron pressed Loren and bowed his head. Their location has a certain angle from the door, and if they don't lean out, Zhao Jianfei can't do anything about them.

However, Zhao Jianfei naturally had a way to deal with them, and he reached out and touched the grenade on his waist. couldn't help but be slightly stunned. The grenades he carried around his waist had all been used, and only two smoke bombs remained. He looked at Lin Rui helplessly, Lin Rui shrugged his shoulders and signaled that he didn't either. This made Zhao Jianfei a little depressed. Originally, in such a situation, a grenade thrown in it could solve a qiē. But at this time, they didn't have grenades.

"It seems that you can only use smoke bombs!" Zhao Jianfei said in a low voice, "You can't kill them, and you can choke them to death!" He took out a yellow phosphorus smoke bomb and was about to raise his hand to throw it in. was stopped by Lin Rui. Lin Rui said in a low voice, "Wait a minute." ”

Then he used a communication headset to contact Yelena, "Yelena, the third row of windows on the east side of the sixth floor." Out of your sniper range?"

"No, but if I move around, I should be able to see it. Yelena whispered, "What's wrong?"

"Nothing, change to an infrared sight. Wait a minute, and the room will be filled with a lot of smoke. The people inside can't breathe and can't rush out, so they will naturally lean to the window to get some fresh air. Lin Rui said in a low voice, "One of these three people is Luo Ren, do you know what I mean?"

"Got it, whoever poked their head out, I'd get a headshot. Yelena ran quickly with the gun in her hand and moved to the other end, so that she could comfortably aim at the position that Lin Rui said.

Zhao Jianfei smiled and said, "You kid, it's really poisonous!" After speaking, he pulled out the safety bolt of the yellow phosphorus smoke bomb, and then threw it into the room. The smoke bomb burns rapidly, the explosive pipe explodes the bomb body, and the yellow phosphorus is dispersed into the atmosphere and combusted with oxygen to form phosphorus pentoxide, forming a large smoke screen.

The detonation of such smoke grenades in cramped spaces is intended to be dangerous, because the combustion of yellow phosphorus consumes oxygen and produces large amounts of phosphorus pentoxide. This is a gas that is toxic to the human body, one is the lack of oxygen, and the other is the large amount of toxic gases. So the danger in a small space is actually very large.

The red baron is an old fritter who has been on the battlefield for a long time, and he was startled when he saw Zhao Jianfei throwing a grenade in. However, the explosion did not produce fragments, which made him feel a little relieved. But as soon as he saw that it was a yellow phosphorus smoke bomb, the red baron's intestines were full of regret, and he simply cursed Zhao Jianfei's eight generations of ancestors in his heart.

This bastard is so poisonous, he wants to smoke us out with smoke bombs. He stayed outside, calmly going out and killing one. Damn, I didn't think he would have this trick again!The Red Baron shouted to Betty beside him, "Go, open the window!" and get him to the window. He's still useful, don't let this old guy die!"
