Everyone was cautious along the way after the attack of the army of pterodactyl monsters, but they were still some way from the base, and when they got to the back, the convoy encountered a little trouble.

Large numbers of abandoned military vehicles and tanks blocked the roads, and even the most powerful horses could only move slowly.

Some of the abandoned vehicles had not even turned off their headlights, so it is conceivable that they must have been attacked at night, and the large number of bullet casings and weapons on the ground proved that there had been a great battle here.

It's just that the losing side of the battle is likely to be human, and all the corpses have become a meal for the monsters.

"Nope! That's impossible! This is our armored tank regiment!! Seeing this scene, an American soldier exclaimed.

They have three regiments and one brigade stationed here, and these armored weapons in front of them are all from the 137 armored tank regiment, what kind of monster can take out a unit with more than 90 tanks and armored vehicles overnight?

"Where are the rest of your troops?" Seeing these tanks, Ling Hao was also worried about whether his armored vehicles were really safe?

"They are all stationed on the periphery of the Red Arrow base, and the 137th Armored Tank Regiment should be stationed inside the Red Arrow base, if they meet here, then it means that the situation of the other troops is not optimistic!" American soldiers still can't believe that their army has been defeated.

"Looks like we need to figure out how these monsters managed to defeat the tanks, and from the looks of the tanks they don't seem to have taken any damage." Because there were too many roadblocks, Ling Hao asked the No. 1 armored car to open the way first, leaving the No. 2 armored car to prepare to find out.

David and Ollie also followed Ling Hao to inspect the tanks, but the three of them found that the tanks had not been damaged from the outside, but all the hatches were open.

"Let's go inside." Climbed into the tank and Ling Hao got into it directly.

No blood was found inside the tank, but it looked very messy, as if the people inside were in a hurry to escape and didn't care about anything else.

"David, help me get an air detector in the car." Ling Hao wanted to check it more carefully.

Soon a portable detection instrument was brought by David, and Ling Hao took the instrument and began to test the air in the car, and the results showed that the air in the car was full of many neurotoxins.

Fortunately, Ling Hao and the others would wear gas masks as soon as they got out of the car, otherwise they would have been guessed to have been hit, and when they learned of the existence of these toxins, Ling Hao also figured out why an armored tank regiment would be wiped out so easily.

You must know that if you want to protect against poison gas, then the tank needs to be specially modified, especially the US tanks of this era, plus they can't imagine that the monsters will release poison gas.

If you guessed correctly, these neurotoxins can control some of people's behavior, which explains why the people in the tank "walk" out of the safety of the tank after being attacked.

Now that the situation has been ascertained, Ling Hao asked David and them to go back to the car first, in order to avoid bringing toxins into the car, the three of them carried out a simple disinfection procedure outside the car.

Ling Hao's armored vehicle has the function of anti-radiation and anti-biological and chemical weapons, which can isolate all toxic gas radiation, and the internal circulating oxygen supply system can allow the crew to survive in a sealed environment for more than 3 days, and can also be switched to an external air filtration system if necessary.

"How's the road up ahead?" Through on-board communication, Ling Hao learned that Ling Yi's No. 1 car had cleared the roadblock, and the road ahead was unobstructed, and car No. 2 could continue to move forward.

Soon the two cars gathered together again, and according to the radar convoy, they avoided some large monsters, and although it was a little wasted, they still arrived at the gate of the Red Arrow base after 2 hours.

But the situation here has changed significantly, although the air was filled with white mist, it was not as thick as here, Ling Hao could only see things within a few meters of the surroundings, and if he didn't bring an infrared thermal imager, he didn't know if there were monsters attacking.

If Ling Hao's guess was correct, the center of the base should be the "door" that was opened, and the source of all the fog was here, so it was reasonable that the fog here was even thicker.

At this moment, the ground began to shake violently, like an earthquake, and several women in the car were shaken, and little Billy also squatted on the ground with his head covered to prevent him from falling.

"Boss! Come and see!! When the shaking stopped, a soldier informed Ling Hao of a major discovery.

"What's the situation?" Ling Hao came to the front of the car and looked at the radar screen.

"It may be a pterodactyl monster, but the scale is more than ten times larger than the previous one!" The soldier gave his opinion based on the huge red dot.

"Aren't they moving?" Looking at the motionless red dot on the radar, Ling Hao asked.

"This red dot only appeared during the earthquake just now, and the radar did not detect it before." According to the soldiers, the monster represented by the red dot should have just come from the "gate", which means that according to the distance shown by the radar, they are likely to be only 2 kilometers away from the "door", which also shows how large the Red Arrow base is.

"Has the cause of the earthquake been identified?" Ling Hao was also very concerned about the source of this earthquake at this time.

"The system shows that the epicenter is at the red dot, and the epicenter is 0 meters underground, which means that this is a vibration caused by an external force hitting the surface!" The soldier reports the results of the analysis.

"The radar locks onto the target to see when it will move, and the convoy first goes around the outer circle of the base to find the entrance to the underground base that the American soldiers say." Ling Hao knew that this time it was definitely not as simple as the "Pterodactyl Monster", so he could only go and find the underground bunker of the Red Arrow base first, and most of the information about the experiment of the Red Arrow Project was in it.

According to the memories of the three American soldiers, the underground bunker should be located in the northwest of the base, where there is a small hill bag, and the cave under the mountain bag is the gate to the bunker.

Because most of the work of these three American soldiers is on the periphery of the base, they only know a rough idea of the distribution in the base, and they have never seen the cave with their own eyes, and they have only heard friends who have been on duty there mention it.

However, since he had the approximate location, Ling Hao felt that it was still necessary to look for it, for the fog and monsters, he believed that the scientists in the base must have relevant records, and more importantly, the design diagram and operating principle of the "door" in the center of the base must also be there.

For the only high-tech in this world, Ling Hao will not give up easily, you must know that the device that can connect to another world is simply a BUG.

If you have enough worlds in the future, you can choose a world as a springboard, build countless "doors" there, and then go one by one to get the resources and technologies you need.

Of course, all of this can only be implemented after obtaining the "door", and it would be even better if scientists who had participated in the Red Arrow Project could be found in the underground bunker, and the sturdy bunker would definitely have some emergency supplies in stock, and it would not be impossible to meet the surviving scientists at that time.
