As for why Cai Wenjie decided that these people were mercenaries rather than ordinary survivors, the most important thing was the equipment they were wearing.

What these people wear is neither domestic standard equipment nor civilian equipment, but a foreign brand, and usually these equipment is the favorite of mercenaries.

Except for the mercenaries, the regular army won't wear these at all because they already have a better choice.

Soon these people, or mercenaries, were surrounded by Cai Wenjie's armored forces. They couldn't run away if they wanted to.

"Tell me, who are you and what you have done within the borders of our country!"

"Hey! Hey! Hey! Calm down! Calm down! Don't shoot. Let your men restrain themselves. We're not bad guys. We just got lost and broke into here accidentally. We'll go right away, so don't point that thing at us."

Obviously, these people were very afraid of the weapons on the armored vehicles. They quickly said that they just accidentally broke into the border and were willing to leave immediately.

"Sure enough, they are foreigners. Do you think the border is your home? Come and go if you want? Come! Get their weapons! Then escort them to the large army for interrogation!"

"Yes!"

Soon, in the armored vehicles surrounding them, more than a dozen tall soldiers came down, and then without saying a word, they went straight up to a capture and controlled several foreign mercenaries on the ground.

"Hey! Easy, you're hurting me"

"Stop talking nonsense! Cooperate obediently, or I'll beat you unconscious."

A tall and strong northern soldier pressed the mercenary directly with his body, and then controlled his arm with both hands to avoid being violently injured.

To tell the truth, even up to now, these mercenaries haven't figured out the situation. They just carried out a simple task of sending several exiled people of country Z back to country Z. now the escort task has been completed, and they are just on the way back. Unexpectedly, they directly met the armored forces of country Z, and they don't seem to be very friendly.

At this time, after seeing these foreign mercenaries, Cai Wenjie immediately remembered that someone had reported that a foreign spy was still detained in his gathering place. Cai Wenjie had reason to suspect that these mercenaries came to rescue the imprisoned spy, but they were controlled by himself just after entering the country.

After controlling the foreign mercenaries, the soldiers handed over their weapons and equipment, tied them together with ropes, and then threw them on the back seat of a infantry vehicle to take them back to the big army.

"Keep alert, let's go!"

The armored troops set out again. This time, there was no accident or anything else on the way. They safely arrived at the fortress where the large forces are carrying out the finishing work.

Although it has only been a few hours since the large troops were stationed in the fort, they have almost arranged the peripheral defensive forces. A large number of heavy machine guns and various defensive weapons are arranged in the peripheral part of the fort. The whole fort is completely surrounded by simple walls, leaving only four channels for vehicles to enter and leave, There are no other exits.

The purpose of this is to avoid being forced by mutant zombies to break through the wall and break into the interior of the fortress for destruction.

And several checkpoints have been set up in each channel, mainly for other accidents.

Cai Wenjie looked at the simple wall five meters high and two meters wide built in just a few hours. He couldn't help but sigh that many people are good. Unlike him, he can only spend points in the mall inside the system.

Soon Cai Wenjie took his armored vehicle troops directly to the first checkpoint.

"Hello, please show me your officer's card or any certificate that can prove you"

A sentry conscientiously fulfilled his responsibilities. Even if he saw that the armored vehicle behind him must be his friendly army, he still stopped the motorcade for routine inspection.

Cai Wenjie had no comment on this, but simply took out his officer card and handed it to the sentry in front of him.

"We are the guerrilla troops who set out first. This time we came to replenish ammunition. Can we enter?"

After carefully checking the officer's certificate, the sentry immediately returned the certificate to Cai Wenjie, then saluted and replied.

"Please come in!"

Then the sentry waved to the other sentries behind him and said.

"No problem! Release!"

After receiving the officer's license, Cai Wenjie ordered the armored forces to move on. No one could stop them anymore.

Soon, after several checkpoints, the armored forces led by Cai Wenjie came to the interior. This is the core area of the whole fortress and the most heavily defended area. Unlike the external simple fence, although there is no fence or other things, there are a large number of near defense guns and light edge towers.

Even if zombies break through the external defense into the interior, it is absolutely impossible to break through the defense here. Among other things, the numbing firing speed of the near defense gun and the dense barrage can block the attack of most corpses, not to mention the light edge tower of almost black technology. Although the attack speed of the light edge tower is relatively slow, But the light prism tower can scatter and attack mutant birds in the sky and zombies on the ground at the same time.

And the damage of the light edge tower increases linearly with the number of light edge towers. For example, if the attack of one light edge tower can cause minor injury to the special-shaped fighting beast, the two light edge towers can cause serious injury to the special-shaped fighting beast, and the three light edge towers can directly kill the special-shaped fighting beast.

Of course, this is only possible under the condition of fire gathering.

Cai Wenjie looked at the rotating optical prism tower and was still a little envious, but there were also design drawings of the magnetic storm coil in his own system space. As long as he returned to his gathering place, he could build the magnetic storm coil. The attack ability of the magnetic storm coil was no worse than that of the optical prism tower. Even if the two defense buildings were taken out separately for a competition, The magnetic storm coil can directly paralyze the optical prism tower at one time.

Soon, the armored forces came to the logistics department, where all armored vehicles should be maintained and repaired, and ammunition and materials should be replenished. While the vehicles were to be maintained, all soldiers had to go to the temporary barracks for rest. Cai Wenjie was no exception, but because several foreign mercenaries were caught today, we had to deal with these mercenaries first, Cai Wenjie can rest.

"Get those captured mercenaries out and send them to the interrogation room for interrogation by professionals."

"Yes!"
