Holding the Qingyou Sword in his hand, Gu Qing sighed with emotion: "I haven't done dissecting work for a long time, and I don't know if the craftsmanship is rusty." ”

Although there was no scalpel, with Gu Qing's current strength, the degree of control of the strength was still very accurate, standing in place and waving the sword blade at the barbarian corpse, the sharp blade suddenly tore the clothes on the corpse, revealing the skin that had completely turned dark purple inside.

Unlike the Central Plains martial arts, the internal force in the body will dissipate after death, the capital of the barbarian is the body, even if he is dead now, the strength of the body is still there.

This barbarian is worthy of being an innate level existence, his skin is very firm, and he is as resilient as cowhide.

However, it was still almost impossible to resist the quiet blade, and if he was still alive, it would be difficult for an ordinary sword to pierce his skin.

Instantly cut his chest open, and suddenly a thick black blood flowed out, Gu Qing mastered the strength and angle in his hand, and removed the flesh and blood inside it little by little, disemboweling his belly, revealing the ribs and some organs inside.

Gu Qing picked it up with the tip of his sword and observed it carefully, this barbarian's internal organs were all larger than ordinary people, and there was a layer of black filth attached to the surface, which was thought to be a toxin carried by leech spores, but it did not completely invade it.

Eighty percent of his blood has turned into a thick, black, fouling liquid that is part of the leech's properties.

The bones, like those organs, are only dull from the toxins, and there is no leech spores attached to them.

The gap between the congenital level and the acquired level is indeed huge, Gu Qing said to himself while carrying out the inhumane dissection business: "It seems that his death is not caused by leech spores, but even if he is dead, the zombie virus will spread throughout his body, and finally transform him into a zombie, why is there no reaction." ”

Gu Qing dissected his whole body, and found no trace of leech spores, these spores did not go deeper again after contaminating his blood, but disappeared, which made Gu Qing full of doubts.

Suddenly, Gu Qing skimmed the two black holes on the corpse's skull, which were originally the location of the eyes, but after the eyeballs were shot by Gu Qing's black needles, the toxin began to spread, turning it into a hole full of black blood.

Underneath the hollow, a lot of black blood oozed from the corpse's mouth and nose.

"Is it ......?"

Gu Qing's sword blade turned upwards and picked open the corpse's throat, and a large amount of black blood suddenly gushed out.

"There's so much blood pooling up in my throat."

Then Gu Qing found that among those bloods, there were many tiny creatures that were constantly writhing.

It's just that these creatures are gradually losing their vitality and finally turning into silence, as if they are dead.

These creatures were too tiny, if it weren't for the connection in the underworld, Gu Qing would not have been able to spot them from the thick black blood.

"All the leech spores are all gathered in the throat, are they heading in the direction of the skull, why are they stopped here?"

In the end, Gu Qing performed a craniotomy on the corpse and found that the other party's brain had completely turned into a puddle of foul-smelling dilute jelly.

"Because of the black needles of the cow's hair, all the other party's brains were corrupted, so the leech spores failed to occupy the brain, is this the real reason for his death?"

Gu Qing thought that the weakness of those ordinary zombies in Beiguang County was also the brain, and felt that this statement worked.

"It's been destroyed, and even the zombie virus can't do anything about it."

Gu Qing turned around and controlled a skeleton zombie to come closer, and cut off its head with a sword, and suddenly the skeleton zombie's body seemed to have lost its connection, collapsing to the ground, and the spore matter attached to the bones gradually lost its activity, and finally it was dim, without the spore substance, those bones also became loose, and only some muscles and bones were adhered to each other.

Gu Qing opened the skull and took out its brain, only to see that this brain was completely different from that of the innate barbarian, although this brain had also turned purple and black, but the appearance was tightly wrapped by a thin film, and in general, the brain had not changed much, but the color had changed.

"First, release toxins to erode and corrupt the body, then attack the brain, so as to control the entire body, and then the zombie virus runs the whole body, transforming the barbarian body into skeleton zombies, and finally divides a part of the spores to attach to the bones, turns into a substance to wrap it, and connects with the spores in the brain, but the most important thing is the brain."

After a series of tests, Gu Qing finally figured out the characteristics of leech spore infection: "The shortcomings are a little obvious, decapitation is useless." ”

Shaking off the dirty blood on the blade of the sword, Gu Qing took out a handkerchief and tried to clean it, and inserted the Qingyou Sword back into the scabbard.

"But the advantages are also obvious, I didn't expect this poison to be so powerful, even the body of a barbarian can't resist it."

Now it's useless to stay outside, Gu Qing turned around and went back to the base, as for the remaining skeleton zombies, Gu Qing directly brought them back to the Valley of the Wicked, now that the base guards are insufficient, let them fill up for the time being.

The dark shadow in the deepest part of the Far North has always made Gu Qing have some scruples, before he was not sure what it was, Gu Qing didn't want to do anything to the barbarians, but Awuta found this base, so Gu Qing had to take the initiative.

"No matter, the barbarians are divided by tribes, and unlike the Central Plains, all of them live in one area, not as scattered as the Central Plains, and this kind of gathering can only be done all at once."

"System, how many leech spores can [Nest] produce at one time now?"

The system replied: "The quality of the spores produced by fusing leeches has increased, and the difficulty of production has also increased, and it can now produce 100,000 spores in an hour. ”

Gu Qing pulled the screen and found the nearest barbarian tribe, this is a medium-sized tribe, Alenta and Awuta are from this tribe, Gu Qing estimated that its area is about the size of three Yunlai towns.

"It's a little little, these barbarians are all extremely powerful, if only a part of them are infected at a time, maybe they will be suppressed."

Then he said to the system: "Let [Nest] go to the biochemical training camp to strengthen it again." ”

The system that received the order immediately put the [Nest] into the biochemical training camp according to Gu Qing's instructions.

And Gu Qing used this time to cast his eyes on Beiguang County on the screen.

The imperial army established a semicircular defensive line on the border of Huacheng County, constantly advancing the encirclement, and Fang Hongcai, the airborne battlefield commander, sent almost all of his troops to the front line after taking over the reins to resist the encirclement and suppression army from the imperial court.
