In the first few years after the nuclear war, the sky was covered with radiation clouds that blocked the sun, and the entire earth fell into a brief Xiaoice period, and all living things struggled in the bitter cold, including the first generation of mutant creatures.

When the radiation clouds dissipated and the sunlight shone the earth again, these mutant creatures that evolved in the dark were powerless to resist the strong ultraviolet rays in the sunlight, so they took refuge in dark corners, especially confined spaces such as subways, tunnels, and caves, which have always been the favorite hiding places of mutant creatures. Today, this kind of place can be said to be a step-by-step crisis, and if it is not necessary, Ding Hao really does not want to come to this place to wander around.

However, it backfired, and some things can only be found here.

Please wait a moment while you are scanning......

There is a small circle in the center of the PDA screen that keeps rotating, and there is a percentage number in the middle that is slowly increasing from 1%, and small dots begin to appear on the originally dark screen, most of which are white, and a very small part is other colors.

By the time the scan is 100% complete, the screen is almost pure white.

After the scan was completed, a total of 999999+ mutant organisms were found in the scanning area

Level 5 mutant creatures: 1

Level 4 mutant creatures: 6

Level 3 mutant creatures: 197

Level 2 mutant creatures: 207629

Level 1 mutant creatures: 999999+

There is an oversized nest nearby, so it is recommended to leave immediately.

The response given by the PDA is correct, but if you don't enter these so-called nests, how can you catch the escaped test subject?

Ding Hao put away the PDA, and then began to move the obstacles blocking the entrance to the subway. Stones, billboards, car wreckage...... The garbage was removed by Ding Hao one by one, and finally revealed a small hole large enough for one person to pass through, and the fishy smell and moisture with strong radiation suddenly gushed out from this small hole.

The accumulated rains carry most of the radioactive material on the surface underground, so mutated organisms in the underground area are usually stronger and more difficult to deal with than those on the surface. Ding Hao put on a gas mask, turned on the night vision mode on the tactical eyepiece, and then entered the subway in a hidden state.

Although the number of mutant creatures shown on the PDA is scary, most of them are just first-level mutant creatures that have no eggs, and the so-called first-level mutant creatures are the difference between mice and hamsters compared to ordinary creatures, and they can be easily killed, and the real thing to worry about is the six fourth-level mutant creature leaders and fifth-level mutant creature lords.

The temperature in the subway was high, about 20 degrees, and the humidity was very heavy, and Ding Hao had not taken a few steps before a layer of water beads condensed on his body.

There were no rats here, though, but there were a lot of corpses piled up at the entrance to the basement of the subway, and judging by the decay of the corpses, they must have been lying here for at least fifty or sixty years, and a large number of strange creatures with short arms and pitch-black carapaces crawling around on these corpses.

It looks like a variant of some kind of shrimp.

It seems that this is not the lair of escaped experimental subjects, but Ding Hao is not in a hurry to leave, but continues to go deeper, even if there are no escaped experimental subjects here, a large group of experience waiting to be harvested is also very tempting, after all, Ding Hao's strength depends on skills, and skills are linked to levels, if you want to improve the level, you can only find a way to gain experience, this world is different from games, you can't get experience by doing tasks, you can only get it by slaughtering creatures.

Ding Hao looked at the experience bar that had reached level 11 and 72%, and felt that he should be able to upgrade by brushing a wave here.

Pulled the trigger on the mutant shrimp on the ground with a Tesla cannon, and with the sound of sizzling electricity, a dazzling electric arc gushed out from the coil and hit the mutant shrimp on the ground, instantly electrocuting it, and at the same time, the arc also bounced to the surrounding mutant shrimp, and in less than three seconds, the mutant shrimp in the 90° fan-shaped area with a radius of 20 meters in front of Ding Hao were cleaned up.

"Wow, this bunker." Sighing at the slaughter efficiency of the Tesla cannon, Ding Hao walked while electrifying, but the level of these shrimps is too low, and they don't give any experience, which is really a waste.

In order to save electricity, Ding Hao no longer slaughters these little shrimps, anyway, they will only run away, and they will not attack people, maybe they can be considered a threat when they grow up, but they are not qualified now.

According to the law that boys will not miss any corner when playing games, Ding Hao first searched the entire entrance of the platform, and found that this place was once used as a settlement, and many daily necessities are still left here. Apparently after the nuclear explosion, many refugees used to hide in the subway, but the subway was somehow invaded by a group of mutant shrimp, and all the residents of the area died.

While searching for the subway, Ding Hao found something quite interesting.

Wire Trap: An ingenious trap that pops a sharp wire to quickly kill all creatures within a 3 meter radius.

This wire trap is a pile of wires twisted together, with a sensor in the middle, when it senses something approaching, it will release the lock, and all the wires will pop out at a very high speed, like a sharp blade, cutting the approaching object in half.

Although the one on hand is completely rusted and unusable, Ding Hao can quickly make a few of them with the materials and skill interface at hand.

However, it is not enough to imitate, we must be brave in innovation.

According to the principle of electric shock rockets, Ding Hao added three small crystal nucleus batteries on the basis of the wire trap, so that all the steel wires will have extremely strong currents, even if they cut through the opponent's armor, they can also electrify the opponent's life and cannot take care of themselves.

Looking at the palm-sized round cake-shaped electric shock wire trap, Ding Hao thought about it carefully, and then the light bulb lit up in his mind, and continued to revise, and the final product was a 40mm caliber low-speed grenade. When the grenade is fired, the warhead attaches to the surface of the object and the body opens like a petal, revealing the shock wire trap inside, bringing disaster to the unlucky ones who pass by.

I have to say it's a perfect idea! Not only can it be shot with a grenade launcher, but it can also be thrown, and the applicability is very strong.

After making the trap grenade, Ding Hao continued to go deeper, and soon saw some oversized mutant shrimp, these mutant shrimp are one meter tall and three meters long from head to tail, but like those small shrimps, they will not take the initiative to attack, and they will die with a Tesla cannon, Ding Hao knocked on the butt of the gun, and these mutant shrimp will actually escape, which is really interesting.

These mutant shrimp that have grown up should be the adult form of those young shrimps, each of which can only bring Ding Hao 3 points of experience, which is pitiful.

It's not worth wasting ammunition for these guys, Ding Hao didn't care about them after a few electrocutions.

As Ding Hao continued to go deeper, the humidity in the air became more and more intense, and the lenses were soon covered with water droplets, and the sensors on both sides also distorted the picture because of the contamination of water droplets.

The snow-white light of the tactical flashlight tore through the darkness, and the subway that had been sealed for decades was finally revealed to the world again, and Ding Hao saw that the surrounding walls and ceilings were covered with pale green bryophytes, and those mutant shrimp fed on them.

The moss keeps growing down, and the mutant shrimp keeps eating up, and the two reach a small balance.

After a little look at the peculiar ecological environment of the subway, Ding Hao continued to move forward, and soon heard the sound of gurgling water, and finally found that the entire platform of the subway was immersed in water, and the track of the subway became an underground river dug by hand.

Is this a burst of a nearby water pipe?

Ding Hao looked around the wide waiting hall, which has become a kingdom of mutant shrimp, the walls are covered with native plants such as moss and algae, in order to absorb nutrients, the walls of the subway are corroded and fragile, and there are even holes in many places, and now these holes have become the passage of mutant shrimp, and countless large and small mutant shrimp go in and out here.

In addition to these pitch-black juvenile shrimp and adult shrimp, Ding Hao also found several mutant shrimp with a red hard shell, which was more aggressive than the previous two.

Burst! Burst! Burst! The red-shelled mutant shrimp sprayed three mouthfuls of venom from afar, and Ding Hao rolled on the spot to avoid the venom, and the venom corroded the walls into green smoke, making a series of sizzling sounds.

After spraying the venom, the mutant shrimp waved the big pincers and bounced towards Ding Hao violently, but Ding Hao overturned the ground with a gun buttle, and then pulled the trigger on the mutant shrimp elite lying on the ground with a Tesla cannon.

The shell of the Mutant Shrimp Elite, while tough enough to withstand a .357 caliber Magnum shell at close range, is not insulated. In the sound of crackling electricity, the mutant shrimp elite was so shocked that his whole body convulsed, and in less than three seconds, the mutant shrimp elite spat out a mouthful of golden, fishy liquid, and then crawled on the ground and never moved again.

This is the shrimp yellow, the current cooks the brain yellow of the mutant shrimp elite, and then the pressure generated by the boiling liquid makes it spit out its own brain yellow.

This mutant shrimp contributed 45 experience points to Ding Hao, although it is not much, but it can be made up for by the quantity, and according to this momentum, one hundred and fifty should be able to upgrade, which is a good momentum.

Using a Tesla cannon to deal with these mutant shrimp is simply overkill, Ding Hao took out SCAR-H and named the surrounding mutant shrimp elites one by one, the armor-piercing high-explosive shell with 4 times the speed of sound is enough to kill two in one shot, and it is simply too easy to deal with these food-level mutant creatures.

After solving all the mutant shrimp elites, Ding Hao took out the PDA again and looked at it, only to find that his location was only the outermost part of this nest, and it was at least 800 meters to reach the location of the mutant shrimp lord, but the 800 in the underground space was not as easy to walk as on the ground, because Ding Hao didn't know where these subway lines led at all.

However, this problem is not difficult to solve, as long as you find the subway map, and then you can choose the route against the map, so it is much easier and more convenient.

Ding Hao looked left and right, and then found a circuit map obscured by moss on a relatively intact wall.

PS: It's finally done,
