Gerald, male, 32 years old, professional hacker, good at cracking all kinds of terminals, thin and weak, not good at fighting.

Mara, female, 27 years old, Gerald's wife, shapeshifter, ability to change the appearance of herself and others in a short period of time, good at lurking, infiltrating, assassinating.

The couple, who originally lived in Portland's outlying city, were trapped when the mutant rats were infested, but they also happened to escape the purifiers, and as time went on, they were forced to send a distress message as soon as they had stored food and began to run short.

The reason why it is risky is because if the distress signal is intercepted and cracked by the Purifier army, it will not be rats or soldiers or anything that will come to the door, but the air-to-surface missiles of helicopter gunships.

"Mara can provide you with a camouflage that makes it easier for you to blend in with the Molecular Equation Biotech building. Gerald can help you decipher the information you've found in the building, and I think you'll need their help. Xia Na said to Ding Hao. If you're willing to help, hurry up, the Purifiers may find them at any time. ”

"So how do I bring them back? Walking the city gate checkpoint? Ding Hao asked.

"No, we have secret passages." Seeing that Ding Hao agreed, Xia Na finally breathed a sigh of relief, "Follow me." ”

Then Xana took Ding Hao to the cellar of the herring fish bar, which was full of wooden barrels and there was a well in the corner of the cellar.

"The secret passage is down there." Xia Na pushed the wooden lid covering the well, and then motioned for Ding Hao to escape.

"Uh...... Are you sure I'm going down from here? Ding Hao looked at the probe and then illuminated it with a tactical flashlight, but except for the black water surface and the smooth wall of the well, he did not see any entrances and exits that could be called passages. Where's the channel? Underwater? ”

"That's right, the passage is just below the water." Shana explained, "When you get back, you can climb up with a rope to draw water, and the barrels contain a change of clothes. ”

"Okay, then I'll go." Ding Hao sat on the edge of the wellhead.

"That ......" Just as Ding Hao was about to jump, Xia Na suddenly shouted Ding Hao again, "There may be danger down there, be careful." ”

"Rest assured, I'm an expert."

Ding Hao jumped into the well water with a "poof", now it is approaching winter, Ding Hao couldn't help but shiver under the stimulation of the cold well water, and then dived into the water to find the so-called passage, and soon found an arc-shaped exit at a depth of two meters underwater, and then grabbed the edge of the passage and swam towards the passage.

The passage was fifteen meters long, and when Ding Hao surfaced, he found himself in the maintenance room of the city's tunnel.

This tunnel is not a sewer, but was dug as a shelter when the city of Portland was founded. In the original Blue Eagle United States, it was more popular to kidnap civilians to serve as seafarers, so these tunnels, which were originally built for legal purposes, were used by kidnappers to kidnap people. The kidnappers locked the victims in tunnels and sent them to the ship when the ship was ready to go to sea. Portland became notorious from 1850 to 1941, after which the tunnels became tourist attractions.

Pushing away the metal plate blocking his head, Ding Hao crawled out of the puddle, and then opened the map on the tactical terminal to determine the bearing.

The city of Portland is divided into east and west parts by the Columbia River, the East Side has been completely abandoned and has become a paradise for ghouls and mutated creatures, while the West Side has been almost completely recovered, but the rat infestation has retaken most of the area in just a few months, only the city center near the Columbia River has been protected by the Purifiers, Ding Hao's current location is very close to the west defense line of the Purifiers, as long as these tunnels are used to pass through the Purifiers' defense lines, Ding Hao can return to the ground, Then head south to find the two agents of the Volunteers.

However, the Purifiers are a regular army, and Ding Hao doesn't believe that they won't set up defenses in the underground area.

After sealing the entrance on the ground, Ding Hao put his ear on the door of the maintenance room and listened attentively, and after listening for a while, he heard a series of footsteps from far and near.

"Why do we have to patrol here? Wouldn't it be nice to lay some mines or set up some automatic turrets? A lazy voice said dissatisfiedly, "It's so humid here, I feel like my underwear is getting soaked." ”

"Mines or automatic turrets can be destroyed by rats and can only be used to aid defense, and we must not only prevent rats from entering the city from here, but also prevent the volunteers from entering and leaving the city through the tunnels." The other voice was much calmer, "If you are not satisfied with patrolling the tunnels, I can tell the captain to tell you to go around the sewers." ”

"Alas! Don't don't, don't! In fact, I feel that this tunnel is quite good, blocking the wind! ”

Listening to the two walking away, Ding Hao took out the wire and quietly opened the iron door, and then entered a hidden state and quietly followed behind the two soldiers. Both soldiers wore the basic equipment of the Purifier troops, full metal armor, transparent bulletproof masks, flamethrowers, light machine guns, large-caliber revolvers, and each one resembled a barbed turtle.

Following the two soldiers, Ding Hao raised his rifle and was about to attack, but at this moment, the soldier's radio on the left suddenly rang, and Ding Hao had to put the gun down again.

"Water Snake Team 6, what's going on below?"

"Everything works."

"We've been attacked by a small wave of mutant rats, and a few have slipped away, and they may have come to your side, stay alert."

"Understood."

"Ah, these guys can't even kill a bunch of rats." The soldier put away his radio and complained to his companion, "I have to leave a handful for us to solve, really." ”

"You're not bored, just have some fun."

"I don't think it's a fun pastime." That being said, the two soldiers took up their weapons and turned into alert in a state of training.

After a while, Ding Hao really heard a sound of Suo Suo coming from a distance.

"These crow's mouths, what are they talking about?" The soldier on the left grumbled unhappily, then picked up the M249 light machine gun, and the other picked up the flamethrower.

Ding Hao, on the other hand, stepped back a little and began to observe their fighting style with great interest.

As the sound of Si Suo Suo got closer and closer, a large group of black mysterious creatures ran over quickly, Ding Hao took a closer look and found that it was actually six mutant rats with hundreds of small mice, but unlike the information provided by Warneck, these mutant rats all ran with their feet, just like people.

"Fire!" M249 was the first to speak, M249 is the pre-apocalyptic Blue Eagle United States squad light machine gun, but also the most durable suppressive weapon, using 5.56NATO rounds, 750 rounds per minute, a magazine under the bolt, containing a 200 round chain, extremely suppressive.

Under the strafing of M249, the six mutant rats suddenly burst out of blood holes, and the mutant rats were at best just some rats that became bigger and walked on two legs, with low defense and no resistance to fighting, and soon fell to the ground one after another, but the big rats fell, but the little mice rushed over without fear, and at this moment the soldier with the flamethrower moved, and a ten-meter-long fire dragon spewed out instantly, completely covering the little mice in the passage, under the burning of the flames, these mice made a terrible squeak, Soon it was quiet again, except for the crackling of the scorched remains of the flames and the stench of the burnt proteins.

"Call the Eagles, this is the Water Snake Team Six."

"This is an eagle, have you found anything?"

"We've encountered six mutant rats and a bunch of baby rats, and we've wiped them all out, and we're done."

"Roger, hard work, Water Snake Team Six."

"Alas, no matter what, the last word is hard work, thanks, it's really greasy!" The soldier with a light machine gun put his gun on his shoulder, "Why can't we get some real reward?" ”

"What reward do you want?"

"Of course it's money, even if it's ten dollars for killing a mutant beast."

"Then you go dig the crystal nucleus yourself, these are all private trophies."

"But do these guys have crystal nuclei?" The Evolver soldier walked up to the mutant rat and shot a few more shots at the mutant rat's head, sending flesh and blood flying, "Look at these guys, they're so big, but they don't even have a white crystal nucleus. ”

"Then you'll have to ask the people who are going to ask the molecular equations, why don't they put some crystal nuclei in them when they make biological weapons."

"Those freaks, I'm not going to ask, okay, let's go ahead and take a look around." With that, the soldier turned and walked forward.

After taking two steps, the soldier didn't hear the footsteps of his companions, and couldn't help but turn his head away, just about to say something more, but he was frightened by the scene in front of him and couldn't speak: just a turn of his head, the teammates who were still chatting one second will be gone the next second!

Seeing the headless corpse slowly falling, the soldier pointed at the sides with the machine gun in his hand with trembling teeth: "Who...... Who's there? Go out...... Come out! ”

The last thing the soldier saw was a dazzling blue light, and the 7.62mm high-explosive bomb was pushed by the crystal nucleus and electromagnetic coil, tearing his head to pieces like tearing paper.
