Song slowly turned the infrared thermal imager at an angle, aimed it at the northernmost tower of the castle, adjusted the focus, and pressed a button, and a blurry image appeared on the display.

Although it is daytime and the quality of the image will be affected to a certain extent, you can still see the shape of a white tower - there are no anomalous color patches inside the tower and shallow underground, which means that there is no living life there.

Except, of course, cold-blooded animals.

These cold-blooded creatures, because their body temperature changes with the environment, their images, generally projected on the thermal imager, are easily confused with the surrounding environment, and they cannot be distinguished at all.

You'll have to find out for yourself!

"You're supposed to be tasked with recording these images, right? It should be done now! I'm going to go in and have a look, and you'll be careful when you get back to the city. Qi Lin said to Song Xiaodie as he checked his equipment again.

"I'll go in with you." Who knew that Song Xiaodie suddenly pursed her lips a little unhappily, and at the same time, as if to show that she also had a lot of combat power, she pulled the compound bow in her hand slightly, and stared at Qi Lin stubbornly, with a big meaning of "If you don't let me follow you, I'll shoot you cold arrows in the back".

"If you think clearly, you may hang." Qi Lin said lightly, if this girl must come along, there is no need for him to refuse, after all, a first-level evolutionary can already be regarded as a good help, and due to Song Xiaodie's special situation, now she and Xiao Lei are the only people Qi Lin can trust in the game at present.

"I'll run by myself if I'm in danger, I don't need you to protect me." Song Xiaodie glanced at Qi Lin, and Qi Lin was a little surprised to find that this girl's white eyes were quite charming, and she was estimated to be a disaster when she grew up.

"Color is emptiness, emptiness is color, I'm not a perverted Lori control......" Qi Lin recited silently in his heart a few times before he deliberately pretended to have an expression of indifference, and said a little coldly:

"Ahem, I didn't say I wanted to protect you, I mean, if you hang up, the attribute is cleared, don't talk about it, if the thermal imager is lost, do you have the money to compensate your employer?"

"I can hide the instrument in the wall, and if I die here, I can come and get it when I am resurrected."

Although I don't know why Song Xiaodie is so persistent, it seems that she is determined to follow, and Qi Lin is not afraid that the other party will have any unfavorable thoughts about him, after all, in the real world, the distance between the two is less than ten meters.

"Okay, you get these things done, I'll give you five minutes."

……

Five minutes later, Qi Lin and Song Xiaodie, who had finished the preparation, slid into the castle through the inside of the outer wall along a rope.

The two of them settled in a low brick house, which was used by the servants who were responsible for the various chores of the castle when the castle was still inhabited, and it was the worst living conditions in the castle, even more dilapidated than the ruins of the barracks at the entrance of the castle.

However, it is precisely because of the remoteness of this place, which is far from the courtyard and square of the castle, that the two of them do not have to worry about bumping into some mutated creature "Rua!" "Give yourself a bite.

Song Xiaodie's evolutionary genes come from an elite-level mutant Scottish Hound, the outstanding attribute is agility, the main weapon is an alloy composite bow, and has an active burst skill of [Hunting], which can greatly improve the four basic attributes of strength, agility, physical fitness, and perception in a short period of time, and can also improve their concentration, and the effect is that the running speed and archery frequency are greatly increased, and the range, power, and hit rate of the arrow can also be greatly improved.

Qi Lin walked in front, and Song Xiaodie was twenty meters behind him, such a distance could not only allow the two of them to take care of each other, but also once one person was in danger, the other person would also have time to get out and find a way to support.

This is the common position of the two mercenaries when performing tasks - generally recruits with little battlefield experience always like to get together, as if this seems more secure, but as everyone knows, this will not only make their own target more conspicuous, in case they step on a mine or something, they will not have time to react, and if the enemy has heavy weapons, they can kill everyone with just one shell.

"Don't make a sound, pay attention to your feet and surroundings, turn and turn your head as little as possible......"

Qi Lin quickly typed a text into his brain and sent it to Song Xiaodie. Now he suddenly has the illusion that he seems to have returned to the battlefield a few years ago, and Song Xiaodie is a new recruit who has just been recruited by the team.

In the castle, due to the low radiation of the soil here, the wild grass grows very luxuriantly, and the height is enough to reach Qi Lin's waist, as long as the cat is waisted, this grass can provide the best cover for the two of them.

As he walked, Qi Lin suddenly felt as if he had kicked something under his feet, and he immediately stretched his left hand back, palms facing Song Xiaodie, which in tactical gestures meant "stop advancing".

Swapping the hunting knife he was carrying in his right hand to his left, Qi Lin squatted down and pushed away the dense grass - a dried corpse was revealed, obviously, this is what he kicked just now.

Qi Lin turned over the dried corpse, only to see that the corpse was wearing a decaying security uniform, although the face was extremely distorted and terrifying, but it could still be seen that this security guard was a human before he died, not a zombie or a zombie.

Corpses left over from old times?

Qi Lin carefully examined the corpse and found that it was exactly the same as the half of the fort, and the fatal wound was in the neck.

Unlike the hideous wounds of the half corpse in the fort, the wounds on the whole body of this dried corpse were only two small round holes on the side of the neck.

These two round holes were just located at the location of the major arteries in the neck, and Qi Lin gently cut the skin of the dried corpse with a hunting knife, only to see that the blood vessels under the wound were obviously ruptured and dilated, which was a trace formed by a large amount of blood flowing through here.

The cause of this person's death should be that he was bitten out of two holes in his neck by something, and then sucked all the blood of his body alive and died!

It's just that the more Qi Lin looked at that wound, the more he felt that he was reminded of a creature that only existed in legends?

Although no one has really seen this creature, it is active in various novels, movies, and TV dramas of the old era, and it is one of the indispensable elements of many Western fantasy works.

Legend has it that this creature fears sunlight, silver, garlic, and crosses, prefers to haunt the night, feeds on human blood, and has an inexplicable relationship with bats......

It's just that......

“…… Bloodsucker? Does such a thing really exist? ”

But if it was the work of other blood-sucking beasts, why were there no other scars except for the two holes in the corpse's neck?
