The temperature in the mountains at night is obviously much lower than that in the plains. The constant mountain wind makes anyone feel unhappy, especially at this night.

At this moment, the soldiers who were on the sidelines of patrol at night were slowly patrolling the defense zone with cigarettes and automatic rifles on their faces.

A soldier sucked the cigarette in his mouth hard, and then sprayed a stream of smoke into the air, but it was quickly blown away by the oncoming mountain wind. He looked at the dark mountain in front of him and spoke to his companion next to him: "Harry, let's go to the kitchen cup of coffee later! It's so cold today, I'm almost asleep!"

Another black soldier with chocolate-like skin threw the cigarette in his hand to the ground and stomped it out with his feet. He said in agreement: "This is good, but if you eat another turkey sandwich, it would be great."

The white soldier immediately smiled and said, "Hehe, you boy just know how to eat, but I feel hungry when you say it."

At this time, a slight sound of breaking through the air suddenly came to the sky at night. The next moment, a bright Mitsubishi arrow was inserted into the eyes of the white soldier. The huge penetration force even penetrated his head directly. In a blink of an eye, the American soldier became a corpse and fell heavily to the rear.

The other black soldier's fate was not much better than his companions. Two arrows were inserted into his nose and the heart of his left chest.

At this time, Helena and the other two on the hills in the distance saw the scene clearly through the infrared telescope in their hands. They did not expect that these people were really using cold weapons to hunt.

Chris, with a silver-haired look on his face, asked to his elder sister, "Sister Chris, these ninjas are too advanced in their equipment, and they can actually be invisible. If they want to secretly sneak into the base below, that shouldn't be difficult!"

"That kind of equipment should be an optical invisible device! This kind of technology that is still in the theoretical stage, I didn't expect these people to fully develop it. If we get these equipment, then for what happened later." After Milia finished speaking, she looked at Helena beside her. Obviously, they were already moved by this advanced equipment.

Now these American awakened people will sooner or later fall out with the government, so they will pay special attention to anything that can help them. These advanced equipment from the Apocalypse are quite good things in front of them.

At this time, Helena said, "Now is not the time to make the equipment ideas. Our top priority is to destroy the military's strengthening warrior plan. Otherwise, our days will be very difficult!"

Although Helena reminded her two subordinates in this way, she also wanted special equipment that could be completely invisible. Once they obtained these advanced equipment, they would be more secure when facing the military in the future. However, the strength of these allies is obviously stronger than that of their own, so you have to use your brain to get these equipment.

Just as Helena and the other two were talking about the special equipment of the Apocalypse Organization, the outer periphery of the US Secret Research Institute at the foot of the mountain, all patrol soldiers in different directions were killed in an instant.

At the same time, at the gate of a building in the institute, after a sound of the electronics station, the gate suddenly began to slowly open. The two large US ground mechas inside were in standby mode at this moment. A group of preparatory personnel were maintaining the big guy, while several drivers were drinking coffee in a lounge not far away on standby.

These drivers received the order and had to be on standby on the side of the mecha for 24 hours. Once any problems were found, these weapons could be activated at any time to fight the enemy. Obviously, the military attached great importance to this institute and the military. Therefore, the defensive power of the eldest son was invested here, which was also the reason why Helena and his group acted rashly.

If it is started, relying on these heavily armored individual mechas, the awakened humans cannot withstand the bombardment of machine guns and rockets.

Seeing that the gate of the hangar had risen automatically, the staff were immediately looked at him. However, no trace of anyone was found. The mecha drivers who were on standby in the lounge immediately ran out and prepared to board the mecha at any time to deal with the enemies that appeared.

But the next moment, everyone in the hangar, from the staff, the mecha drivers suddenly covered their necks with their hands and fell to the ground with pain.

The next moment, a large amount of blood suddenly surged from the necks of these people. Through their hands covering their necks, it continued to flow to the ground. Suddenly, in this huge hangar, there was a subtle struggle sound before death.

Just as all the people in this hangar began to lose their lives, the same situation occurred in another warehouse of the institute. The ground was full of people who were about to lose their lives. At the same time, a light single-soldier mecha had been cut to pieces and fell to the ground. A trace of electric sparks continued to explode in the damaged place, and a terrifying knife wound appeared on the body of the driver inside, a large amount of internal organs and blood, dyeing a ground red.

The control room responsible for monitoring the outside of the institute was now covered with corpses. The ground was full of headless corpses with their heads cut off, and the splashed blood dyed the walls and the surface of the instrument red.

Soon the ground building located in this secret US military institute was completely destroyed in just five minutes. However, the guards did not even see the shadow of the enemy and went to see God.

At the same time, the special elevator leading to the underground facilities of the Institute was started and drove downwards. But what is strange is that there was no trace of people in the elevator.

This special institute controlled by the United States is like most secret institutes. Most of its main buildings are underground. The buildings on the ground are completely used to conceal underground facilities.

It is undeniable that after experiencing many major wars, the United States still has such advanced scientific research facilities, which shows how powerful this country is.

This special research institute specializing in conducting biochemical experiments, because of the special nature of its work, the experimental areas located underground are planned very strictly, and in each important experimental area, there is a pair of special forces for twenty-four hours of protection, in order to make accidents happen.

In a special room far away from those laboratories, a large number of air-conditioning equipment responsible for providing air circulation to the underground base are constantly operating. It is constantly dispatching a large amount of waste gas for this large research institute that is 50 meters deep underground, and at the same time, it is constantly transmitting fresh air to each research institute area.

In the control room responsible for controlling all the air conditioners of the institute, four employees wearing blue work clothes were chatting. There was no special attention to the ventilation systems of the institute.

After all, this place is a research institute of the United States. The equipment inside is quite advanced, and all mechanical equipment is controlled by a computer. If any problem occurs, an alarm will be issued immediately.

At this time, the automatic door in the control room suddenly opened, and the special door opening sound immediately attracted the attention of the staff members who were chatting. They immediately turned around and looked over, but did not see anyone.

At this time, a white employee with two beards looked at the automatic door that was still open. He immediately cursed: "Fuck, what the hell is this door! It was opened for no reason, and it was closed a lot. Has the maintenance here not been completed? How can we work with peace of mind? The squad leader, it seems that he has to notify Old Harry that they will come to practice in the maintenance class."

The other three staff members nodded immediately to express their agreement with this mustache. In fact, they are just to make it easier for them to be lazy. If the door is open from time to time, it will be annoying for these people.

The squad leader who was called by the beard was a fat white man with a beard. After drinking a cup of black coffee in his hand, he slowly spoke, "Mike, go and notify the guys in the maintenance department now. They will come and check these automatic doors tomorrow morning so that those guys will not be doing anything all day."

A small white man with a hat tilted, nodded immediately and said, "Okay, I'll go now. After I come back, I will continue to play like this. I just lost 100 dollars."

The bearded man immediately laughed and scolded: "Hahahaha, Peter, you a bad guy, know how to play cards. Don't worry, the card game will be waiting for your kid to come back. Now let's notify those guys in the maintenance department."

The little man named Peter ran towards the gate immediately. But after the sound of a sharp blade piercing through the **, a sharp blade suddenly appeared in the staff's body.

The next moment, a large amount of blood began to splash out, and the ground suddenly became bloody. The staff member named Peter, who was stabbed by a sharp blade, couldn't help but look down at the blade that was infiltrated into his body. However, his mouth could not make any sound, and a trace of blood began to flow out from the edge of his mouth.

After seeing the scene of a colleague being penetrated by a blade out of thin air, the other three staff members immediately opened their eyes to almost all of them. They didn't even react to the sudden situation.

But the next moment, these staff members followed the footsteps of their companions. The guys sitting on the chair suddenly had several blood-stained blades on their necks and hearts. They lost their lives in a flash. The bodies began to twitch unconsciously.

And the blood on these dead staff kept splattering on the consoles beside them, turning them into blood.

At this moment, the automatic, which was originally in the on state, immediately turned off again. Gradually, several figures gradually showed their figure from a transparent state.

More than a dozen ninjas in the room wearing black enhanced combat uniforms were looking at the four corpses on the ground with cold eyes. At this moment, with two long knives on his back, he slowly walked to the air conditioner control equipment. He ignored the blood on the control panel and gently pressed a few buttons and began to check the ventilation equipment.

Soon after, he ordered to the surrounding subordinates: "Now start carrying out special tasks, and you will immediately release all the special coma agents into the air circulation system of the base."

As several ninjas connected the large steel cylinders on their backs onto the ventilation system, a large amount of white gas began to spread continuously toward the institute along with the ventilation duct.

At this time, the researchers and guards in different areas of the underground base had no sense of the coming gas. But a few minutes later, the people in the base were inhaled and released through the ventilation system. The coma was constantly released. They began to fall into the ground as if they were drunk, and gradually fell to the ground with weak strength and completely removed their perception.

After watching the special coma being released for ten minutes, he turned around and looked at the subordinates around him, and spoke in a simple tone: "Now start to go to all parts of the base immediately, and send a signal to the receiving troops. They want to rush here to meet immediately, and once this mission is completed, they will return to the base immediately."

The ninjas surrounding Shina immediately spoke in a firm tone: "Yes, leader!"

Looking at the subordinates around him who had no extra words, he nodded in satisfaction. This is what the ninja wants to do, absolutely obey the orders. He took the lead in activate the optical invisible device on his body and entered the invisible again.

After seeing the leader, the ninjas pulled out their knives and then all entered an invisible state. As the door of the air-conditioning control room was opened again, these special troops of the Apocalypse organization immediately rushed into the base's passage.

Although he used the powerful coma agent developed by Lao Zhou and the others before, he did not expect any accidents in this mission. Therefore, he activated the optical invisible device again.

As we moved forward in an instant, we could see gun guards and researchers wearing white research suits everywhere in the channels of this institute.

Soon some ninjas found the command room in the base. They immediately looked at the command they received before and began to use the communication equipment in the base to contact the follow-up troops still located in the mountains to rush here immediately. At the same time, they also reported the locations of the main laboratories and computer host rooms in the research institute to Shina as soon as possible.

After receiving the reward from his subordinates, he immediately went directly to the area where the laboratory was undergoing a physical strengthening experiment. Along the way, he saw a large number of fully armed soldiers falling down in the passage, and obviously he attached great importance to this experimental military. However, under the special attack of the ninja troops of the Apocalypse Organization, this place was completely captured in the shortest time.

When he walked into the large laboratory for human experiments in an instant, the first thing that caught his eye was dozens of huge modulation tanks. Among them, there were more than a dozen people wearing shorts, wearing special respirators, their eyes were closed and sealed in it, wrapped in a large amount of liquid.

Obviously these people should be the first batch of military experimenters to strengthen soldiers. Under the modulation tank where each of them is located, there is a special equipment that is recording a series of data in detail.

At the same time, the ground had reached the ground, and most of them were lying next to the experimental instruments. Obviously, these scientists were still nervously conducting experiments before fainting.

After seeing that there was no one who could stand up in a huge laboratory, he immediately removed the optical invisible device on his body. After showing his figure, he seemed to order the subordinates who appeared behind him: "Immediately move all these scientists out of the laboratory, and at the same time start copying and taking away all the data in the institute."

The ninja who received the order immediately took action. The strengthening people created by the Apocalypse organization were several times greater than those of ordinary people. Therefore, they easily carried the scientists who fell to the ground one by one on their shoulders and transported them outwards.

Soon, the laboratory, which was originally filled with scientific researchers, soon became empty. At this moment, he walked to the modulation tanks that sealed the experimenters, and he looked at these test items that had undergone physical strengthening experiments with his calm eyes.

At this moment, some instruments in the laboratory suddenly made a simultaneous sound, and then several testers who were originally in a quiet state suddenly opened their eyes in the special liquids and looked ahead. To be continued...
