The entrance to the basement is in the abandoned base of the Federal Army, hidden in an underground sewer entrance, just because of the previous expeditions, the metal doors and wire mesh that were originally blocked here have been damaged and can no longer be destroyed, and the thickness of the broken metal doors that fell from the ground shows that the Federation period attached great importance to this place. With the dissolution of the Federation, these things naturally can't be done, and this place has become a paradise for folk explorers.

The results of the light brain analysis showed that the entire building was made of extremely hard composite materials, and a large part of the metal doors on the ground were made of black iron. This is one of the strongest materials in the universe, and the shield made of thin dark iron she bought can block the attack of heavy artillery, let alone such a thick dark iron door, this is not as simple as one plus one equals two. I wonder how much effort it took the explorers to blast open this door in the first place?

Entering the underground passage, the first thing I felt was that the visibility of the line of sight was reduced, and the guide's line of sight was completely blocked, and several people turned on their respective luminous devices, so that the entire crypt was exposed in its original form, and from here it looked inside completely like the mouth of a terrifying giant beast, and it was pitch black inside, and a yin wind swept from inside, and the person who blew shivered, not because of the cold but an instinctive intuition. Further on, you can still hear the sound of the wind whistling from time to time, like a woman's eerie laughter.

"Ah!" After all, Ma Xiaomin is an orange-level martial artist, the lowest ability among them, and she is a female streamer, so it is inevitable that she will be timid, she was so frightened that she couldn't help but scream on the spot.

The first few people in the lead frowned, but did not speak.

"What is it called, can you take responsibility for the monster being attracted?" Lu Yuanxun suddenly launched a rush against Ma Xiaomin.

"I'm sorry, I didn't mean to, I won't do it again, please don't be angry, it's all my fault. Ma Xiaomin bowed deeply in the direction of Lu Yuanxun and said with teary eyes, she didn't mean it just now, it was just an instinctive reaction.

"It's unlucky to be in a group with you, Mourning Star, look at it, whatever monsters you encounter later, you'll attract them. Lu Yuanxun continued to chatter and scold. Wang Yujin frowned, she felt that it was too much for a red-level martial artist to bully an orange-level martial artist like this, although Ma Xiaomin's scream just now was a little undeserved, but she didn't mean it, and there was no bad impact, and as a man, it was a little stingy to find trouble with a weak woman.

"I think if a monster comes over later, it won't be attracted by Ma Xiaomin's call. ”

"Who would she be?" Lu Yuanxun looked at Wang Yujin with an unkind gaze

"Don't you know that the sound in the underground walkway will be infinitely amplified, if it is just that sound, the monster will not be able to judge the direction of the sound, but if you chatter like this, you will definitely reveal your coordinates. Wang Yujin's voice is not loud, but it can really make everyone hear it clearly.

And as soon as her words fell, there were already several pairs of bright eyes in front of them.

"Get ready to fight, I don't know who shouted. "Everyone is in their positions.

The monster finally took on its original form, a group of very fast cat-batmons, with a cat-like head and a bat-like body, and wings spread almost exactly like a bat.

It has very sharp teeth, once it is bitten, it will not let go, unless the prey is bitten to death, even if the beast is killed in the process of biting, the blood will still flow into the body of the cat and bat beast, because these beasts have two grooves on the fangs, which is equivalent to the blood groove in the weapon.

These beasts are small and large in size and ability, and the large size of other species is different, but the small size of the cat and bat beast is the commander, they always come out from the role of being a military advisor, not lightly, and let the big body rush in front as the role of cannon fodder.

Judging from the data, they are the most difficult monsters in the underground layer, as long as they are entangled by them, unless all the small cats and batmons in them can be calmed down, they will always call their friends to attack from time to time.

They can also attack with sounds, and the first thing to fight with them is to cover their ears.

"Plug the ears with something, the heavy gunners attack first, scatter their teams first, then the musketeers and melee attacks, the melee ones calculate the cooldown of the heavy gunners, and when the cooldown time of the heavy gunners is up, they immediately back off and let the heavy gunners get out of the way. For the time being, the bald head took over the command of the team.

For the two teams to cooperate, it is better to have only one unified voice, and since the bald head has enough experience, he has temporarily taken on this job. But the premise is that the two teams act in unison, if the bald head uses Liao Yunyang's team as cannon fodder, Liao Yunyang and they will not do it.

The light cannon attacked these cats and bats flying at high speed, and the sound of "boom" was endless, and the cats and bats were scattered by the light cannons, but they did not die, but they were scattered by the impact, and only two or three cats and bats fell from mid-air, which was the most frontal attack.

Wang Yujin is hard to imagine.

"The wings of these cats and bats are very strange, the lines on its wings can transmit sound, and can absorb energy, and even physical attacks can be resisted, it is not simple, you are worth studying! "The light brain has already analyzed the cat, the bat beast, but the more it analyzes, the more interested it becomes.

"Attacks are aimed at the bodies of these beasts, whose wings have a very high defense factor. Said the bald head of the command team. Apparently he also had the information in his hands and had done research on this hairy animal.

In fact, attacking these cats and bats is still the most lethal in melee, but melee killing is slow, and it is directly in contact with these cats and bats, it is easy to be attacked, and they can't be made into a momentum, once they become a potential, they will form a sonic attack, which is also the most powerful attack of these cats and bats in addition to their teeth and claws, teeth and claws will not be attacked as long as they are careful not to touch these cats and bats, but the sound of this thing can be attacked without physical contact, just like human muskets and heavy artillery.

Wang Yujin also joined the battle group, she knew that this was a rare time to practice knife skills, these cats and bats have advantages, but also fatal weaknesses, their weakness is the body, once they are attacked to the body, even if their wings are capable, they will be killed, Wang Yujin stepped forward with the imitation demon moon in his hand, and the knife fell quickly, but it was bounced off by the wings of the cat bat beast, and there was a feeling of being unloaded, and the concussive arm was slightly numb. In addition, she also felt that when she slashed down, the wings on the cat-bat-beast's body turned red for a moment, and she slashed several times in a row to the cat-bat-beast's wings, and sure enough, the cat-bat-beast's wings flashed even hotter.

"It's incredible that these cats and bats can resist attacks through guò's lines that transmit blood and qi to their wings. Light Brain sighed. This also explains the reason why these hairy beasts like to suck blood.

And at this time, Lu Yuanxun beside him saw Wang Yujin continuously slashing at the wings of the cat bat beast, and couldn't help but sneer, he was originally more afraid of her, a pharmacist who can kill people, even he can't kill seven people in a row silently, but now seeing that she knows that it is useless to cut off the wings and still wants to attack, isn't it stupid What is it? A woman who is too arrogant will naturally die early in this kind of place, even if she is a pharmacist. Looking at other pharmacists, they are also young, and you know that Taoguang Yanghui is standing in the back, and there is a pharmacist who is so famous behind him as a mentor.

And Wang Yujin said that there was a senior pharmacist master behind her, but no one had ever heard her name? If there really is such a famous teacher, it would have been said a long time ago! Where would anyone hide it? I am afraid that if there is, there will be nothing to see.

As for the matter of entering the determination in the process of refining the medicinal liquid, maybe the blind cat met a dead mouse and just won the lottery, and such shit luck is not impossible to happen in the interstellar.
