Chapter 47 The Red-Eyed Bat
Chen Dong opened his portable manufacturing panel, and clicked on the column of anti-virus masks

【防毒口罩（消耗品）：布1/1、麻2/2、麻茎皮1/1、活性炭0/2、植物藤蔓1/1】

After looking at the recipe, all other materials are complete.

And coincidentally, most of them are hemp resources.

Including cloth is actually made of hemp, which is one of the reasons why Chen Dong has always attached great importance to hemp.

Because it is so versatile.

Now only one activated charcoal is missing.

However, the coal Chen Dong mined can be used to extract activated carbon.

Chen Dong is preparing to open the core barrier, release his cabin, and then use the raw material processor to make activated carbon.

However, the system prompts that it is on a special map, and there is no way to enter the dilapidated cabin.

Not only that, until now Chen Dong realized that he had no way to open the chat channel.

In other words, after entering the adventure map, you cannot communicate with the outside world in real time.

It is also not possible to exchange any materials in the trading channel.

Chen Dong hadn't grasped this point before.

After thinking about it, Chen Dong directly extracted the raw material processor.

Fortunately, the venue here is big enough to accommodate it.

Although the raw material processor contains a lot of processing options, resources can be upgraded and processed.

However, searching one by one is too troublesome.

Chen Dong tried to put coal resources directly on the workbench of the raw material processor.

【Material: Coal】

【Machinable: honeycomb briquettes, coal blocks, activated carbon, coal powder, cinder.】

Sure enough, as long as one material is selected, whether it is processing this material into a more complex material.

Or decompose into primary materials.

The options related to it will be prompted.

Without hesitation, Chen Dong directly chose to refine activated carbon.

After adding the psychic power, the raw material processor quickly started working.

After a few seconds.

[Obtain: Activated Carbon +10]

Looking at the activated charcoal in front of him, Chen Dong couldn't help being excited.

If there is no raw material processor, I am afraid that even if you get a coal mine, you can only watch helplessly, and there is no way to get activated carbon.

It seems that this A-level map should be his own.

If you have to find someone else, I'm afraid you won't be able to pass a level.

Now that there is enough activated carbon, Chen Dong plans to make two gas masks at a time just in case.

After all, this is a consumable, what if it becomes useless after a while?

[Obtain: Gas mask +2]

[Gas mask: disposable consumable product with high-strength filtering function, which can effectively filter and isolate various harmful gases. After each use, the internal activated carbon will be contaminated with toxic substances, and there is no way to use it for the second time.]

It was so!
Fortunately, he built an extra one. Without hesitation, Chen Dong put on a gas mask.

The gas mask is made of linen, and the parts hanging on the ears are also made of plant vines.

It is soft and comfortable to wear on the ear.

After wearing the gas mask, you can even smell a faint smell of sackcloth.

However, when breathing is very smooth, there is no discomfort.

Just like that, Chen Dong had night vision devices on his eyes, a gas mask on his mouth, and bristles in his ears.

Take out the fine iron spear directly from the core barrier.

Red-eyed bats are too small to use a psionic compound bow against them.

These bats were flying around in the air, and the targets were small, making it difficult to hit them even with the addition of a psionic compound bow.

But their main means of attack are nothing more than sound waves and poison gas, and now Chen Dong is no longer afraid of these two.

Another weakness of red-eyed bats is that their bodies are too fragile.

Chen Dong can rely on his basic spear skills to deal with it in close combat.

However, there is also a flaw, that is, Chen Dong will definitely not be able to catch up with them.

But these bats will not escape in their habitat.

Turn on the navigation, and follow the navigation prompts, Chen Dong went all the way along the winding cave passage.

In such terrain, even holding a bow and arrow is useless.

When he was tens of meters away from the group of red-eyed bats, Chen Dong had already stopped.

The perception of these bats is very strong, and if you go further, you may find yourself.

After thinking about it, Chen Dong took out a shovel from the core barrier.

Start digging in situ.

[Obtain: Soil +1]

[Obtain: Soil +1]

[Obtain: Soil +1]

Fortunately, every time after digging down, the soil will directly enter the core barrier.

No need to clean up excess mounds.

Soon, Chen Dong dug a big hole, and then took out a piece of wood to leave a hole for himself to enter and exit.

Then Chen Dong held a spear in one hand and a stone in the other, and quickly moved forward.

After walking a few steps forward, he saw through the night vision device that there were large and small holes between the crooked walls on the top of the cave.

There were bats crouching inside, their wings falling on them strangely.

With red eyes open.

They had already sensed the movement of Chen Dong coming in.

However, this group of bats was quiet and did not make the slightest sound.

But Chen Dong saw their expressions clearly through the night vision device.

The bat's short forelimbs and small mouth kept chattering.

Chen Dong knew that this was a precursor to the sound waves they were about to release.

Slightly stopping in his tracks, Chen Dong took a look, the black iron treasure chest was in an open space 30 meters in front of him.

Chen Dong picked up a small stone in his hand, looked at it, and threw the stone directly at the bats in front of him.

A crisp "pop" sound.

The swarm of bats suddenly flew up, roaring crazily, and attacking with bursts of sound waves.

And Chen Dong ran away after throwing the stone.

He slipped back to the pit he had just dug like flying, and pulled the wooden planks to cover it.

Even so, the sound waves of the bats were still thumping on the vibrating planks.

However, Chen Dong had a lot of bristle hair stuffed into his ears, and with the insulation from the soil, it didn't affect him at all.

Finally, the movement outside stopped.

Chen Dong went out and threw another stone, and then ran back to hide in the pit again.

The group of red-eyed bats flew up again, sending out bursts of sound waves to attack.

However, Chen Dong, a shameless guy, stayed in the pit leisurely and could not come out.

After repeating this more than 10 times, these red-eyed bats were exhausted.

Even if Chen Dong got closer, they stopped making sonic attacks.

On the contrary, during the non-stop flight, the bat swarm kept dropping excrement in the air.

It fell on the ground and made a sizzling sound, and a burst of white smoke continued to rise from the corroded ground.

However, Chen Dong has the blessing of a gas mask, which has no effect at all.

Watching these bats is exhausting.

Chen Dong didn't hesitate anymore, took out a Molotov cocktail from his hand, and walked forward again.

This time Chen Dong threw another stone, and the bat swarm rushed in this direction again.

Without saying a word, Chen Dong lit the Molotov cocktail and threw it, then turned and ran.

"Hoo!" There was a sound!

The Molotov cocktail exploded with crackling flames.

The eyes of these red-eyed bats are very fragile, and the flames and thick smoke produced by the Molotov cocktails made them bark wildly.

One by one in a panic.

The burning of the Molotov cocktail lasted for a full minute.

After the flames dissipated, there were already many bat corpses on the ground.

Some even gave off a strange smell of meat.
