After Gu Hongbo left, Zhang Yuntian called the remaining two corpse guards in, took a bag of blood from each of them, and then locked himself in the room and got busy.

If it is said that the vaccine of the corpse guard is difficult to manufacture, it is because scientists in the last days have not mastered the technology of DNA recombination, and can only reluctantly cultivate qualified vaccines through some fixed chemical and physical processes and meet the harsh cultivation conditions.

And this is not a problem at all for Zhang Yuntian, he directly used a DNA extractor to isolate and extract the DNA of the vaccine, because the vaccine is actually an inactivated virus, so they also meet the basic characteristics of the virus and are easy to identify.

The extracted DNA is then rapidly generated with a maternal incubator and replicated on a large scale, so that the inactivated virus varieties produced are purer and stronger.

Zhang Yuntian once understood that the so-called hierarchical division of the corpse guard is mainly related to the ability of the corpse guard himself, the first-level corpse guard is generally an ordinary survivor and slave, they are often the product of the real yàn room, melee combat has a certain combat effectiveness, but is not very good at firearm shooting, because the corpse guard no longer has the ability to learn after the transformation, so the first-level corpse guard can only stay at this level forever, and it belongs to the failure of the corpse guard.

Corpse guards from the second level, can be classified into the ranks of elite warriors, they have good driving skills, can be more skilled and accurate shooting, the third level and above the corpse guards are generally fierce criminals or brave warriors, in addition to the above abilities, they also have superb fighting skills, some of them even have special skills, belong to the best of the corpse guards.

For example, the two fourth-level corpse guards beside Liu Fugui were members of a special forces before the transformation, so the combat effectiveness after the transformation was even more terrifying, even if one person fought against seven or eight good fighters, or dozens of hungry zombies, he would not be left behind.

In this last days, the strength of the corpse guard undoubtedly determines the strength of the strength, Zhang Yuntian looked at the whole bucket of corpse guard vaccine in front of him, and smiled sincerely.

In the afternoon of the next day, Li Junhai sent the purchasers back and bought a total of 27 anesthetic guns and dozens of boxes of anesthetics and syringes, which were also very expensive, and almost spent one-third of the nutritional mixtures earned from the black market.

However, Zhang Yuntian is not painful, because they will create dozens or even hundreds of times the value!

Half a month later, on the terrace of an independent three-story building in a black market town, several men in dark green shirts were sitting around the table eating hot white dumplings, their bodies were extremely burly, and their muscles seemed to burst out of their clothes at any time.

The man at the head had neatly combed his small hair and wore dark blue sunglasses, he was a regimental leader of the Grey-tongued mercenaries, nicknamed Black Tiger, and the others were his captains.

"Brother Tiger, these dumplings are so delicious, I haven't eaten them for seven or eight years, and I've almost forgotten what they taste!"

A bald head was chewing and chewing while muttering indistinctly, obviously his mouth was full, but he was still stuffing it vigorously, like a starving ghost who had survived.

There were a total of three plates of dumplings in front of several people, one of which was specially prepared for the black tiger, and the remaining two plates were their food, so no one dared to slack off, for fear that they would eat less than others.

After the black tiger swallowed the last dumpling, he simply wiped the corners of his mouth, looked at the unfinished men in front of him, grinned, and said:

"Look at your unproductive appearance, isn't it just a meal of white-flour dumplings, one by one as if you have never seen the world!"

"Brother Tiger, this is really a long insight, there are still people selling white noodles in the black market, this thing is expensive, if I can eat such a small bowl during the New Year's holidays, even if I don't go to a woman for a month, I am willing!"

The bald head said and drank the soup in the dumpling bowl clean.

"Hmph, you're pretty good at calculating, what is the price of a woman, what is the price of white noodles, are the two comparable? The dumplings you eat are enough to buy seven or eight virgins, if you want me to say that Brother Tiger has the ability to guard the treasure land of the black market, if you are with the other leaders, how can you still enjoy it like now? I don't know where to fight the zombies! Let's talk to Brother Tiger about the right person! ”

The small-eyed man wasted no time in meeting him, and when he mentioned this, the others immediately echoed.

Heihu smiled and said lightly: "You guys don't make a fool of yourself, you have to take care of yourself after eating this meal, we have to make a big deal recently!" If this deal is done, we will have dumplings to eat during the holidays in the future! If someone drops the chain on the way, don't blame me for being ruthless!"

The bald head asked: "Brother Tiger, the guys who can come up with white noodles should have a little foundation, we have to guard the black market, and we have to do business, I'm afraid that there will be not enough manpower!" ”

"Hmph, I noticed from the first day they came to the black market, according to such a long period of observation, they are just a man who leads the team, it looks more difficult, and the rest of the people are all chicks with little combat experience, not to mention that we have transferred the main force of the base this time, just to capture them alive! I don't just want the stock they have, I want to know from them where the white noodles come from! ”

"Don't worry, Brother Tiger!" A big man smiled excitedly, revealing a mouth full of fangs: "As long as the person who comes to my butcher's hands, there is never someone who does not tell the truth!" ”

"Report!"

A soldier came to the door of the terrace, stood upright, then walked up to the black tiger and whispered a few words, then withdrew.

The black tiger pinched the joints of his fingers and made a crackling sound, "What do you say, the prey has come to the door, brothers, we will continue to eat dumplings last night, butcher, you stay, the others will each take twenty brothers to set off with me, remember, the leader will live, and if the others don't descend, they will all be disposed of!" Let's go! ”

Everyone agreed in unison, and rushed out one by one with high morale.

Although the prey only brought a dozen people, and it was only some untrained ordinary people, this was simply vulnerable compared to the seventy or eighty well-trained elites of their own side!

He sat in the armored car, in the middle of the team to control the overall situation, to be honest, to deal with such a weak prey there is no need to use such a large force, but the black tiger has another plan in his heart, what he wants is to surrender without a fight, with a strong military advantage to force the other party to surrender, but also to declare his own force, after this battle, the protection fee of the black market should also rise.
