This is a chemistry laboratory, with simple equipment, small space, and a briefing note on the wall of the "Code of Science Experiments for Primary School Students", not to mention the precision and precious equipment, not even equipped with disinfection equipment. At this moment, the laboratory was filled with smoke, and a short, stocky young man with long hair was holding a light blue test tube, his face excited.

He took out a plastic needle and cautiously walked to the side of the hideous and terrifying head, this is the head of a licking predator, the red-white brain is directly exposed to the air, the long tongue is weakly drooping, the fangs are sharp, just looking at the appearance, it is enough to make people frightened.

The young man focused for a long time with his cross-eyed eyes, and finally pierced into the core of the licker's skull, and pulled out a tube of dark red liquid, he injected the red liquid into the blue test tube, the test tube instantly changed, turning into a fluorescent cyan, he buttoned his nostrils, and looked quite satisfied.

After a few minutes, the medicine in the test tube completely turned azure, the cross-eyed young man became excited, a glimmer of golden light flashed in his eyes, he took the test tube with his fat hand and looked at it carefully, looked at it for a while, and sniffed it with his nose, there may be no taste, he dipped his fingers in a little cyan liquid and put it in his mouth, and smacked his mouth a few times.

"It tastes pretty good." The young man nodded with satisfaction, this potion is apple-flavored, and the experiment should be successful.

When the short and fat young man saw this operation, the scientists had to tearfully take the tofu and hit him to death, without any precautions, not to mention, the finished product was sent directly to the mouth without any inspection.

"Wait, I made it!" The clever and excited hands danced, improvised a hot dance, and at the end of the dance, he called the spitting warriors standing at the door.

"You two, go and inform the chief, and say that my experiment was successful." He is very smart and commanding, and he is quite stylish, he naturally has this confidence, the director of the Qinglong Research Institute, in this realm, he is also the number one person.

"Okay, Director." The two warriors glanced at each other, smiled helplessly, and could only go to Ji Long City. They were sent to stand guard in the elementary school laboratory, not to protect Da Ming's personal safety, but for fear that he would create some strange monster and pose a threat to Qinglong Town.

Ji Longcheng held the cyan test tube, and the horror in his heart was beyond measure, this great cleverness actually created a medicine that strengthened the human body.

Low-level Evolution Elixir [D-Rank]: Carefully concocted by the Genius Scientist with the brain marrow of elite zombies, after taking it, Strength +5, Agility +5, Stamina +5, Mana +50, All Attribute Resistance +10%, and Injury Recovery Speed +20%. Note: There are no side effects, and repeated use is ineffective.

"You did this?" Ji Longcheng solemnly held the cyan test tube. This elixir can be replicated, which means that the humans in Qinglong Town can be fully strengthened, and the attribute points added by the low-level evolution elixir do not seem to be much, only 5 points, but that is for Jilong City itself, for ordinary people, the use of low-level evolution elixir will obtain qualitative changes, double the attributes, and the gap between the physique of humans and zombies will be smoothed out.

"Who else is me?"

Da Ming shook his long flowing hair, raised his chin proudly, and was accidentally pretended by him again.

"How many bottles did you make?"

"A bottle."

"What is needed?"

"The cerebral marrow of a special infected person."

"You make another bottle and come out."

"I forgot !!"

"What !!" Ji Longcheng couldn't wait to dismantle this big clever, such an important thing, he actually forgot the formula.

"Think carefully about how you made it, if you want to be able to mass produce, I will promote you to an official!" Ji Longcheng is pure and seductive.

Hearing that he could be promoted, Da Ming was excited, and he didn't care if he remembered the secret recipe, so he started experimenting, and a few minutes later, he was holding a bottle of azure test tube in his hand.

"Is this okay?" Ji Longcheng watched Da Cleverness pour back, not only added various chemicals to the test tube, but also added fruit vinegar and sugar, this is not science, this is metaphysics.

"Excellent! I promoted you to the director of the first research institute of Qinglong Town! ”

Hearing Ji Longcheng's words, Da Chui is happy to spend no money, his brain circuit is different from normal people, and he doesn't want to think about it, is there any qualitative change in this, it's not okay at all. It's still the science lab of the elementary school, and it's still the commander of the light pole.

Ji Longcheng picked up the test tube and drank the azure liquid in one gulp, his various attributes rose a little, about a tenth or so, unexpectedly, this evolution potion was very delicious, similar to the apple-flavored Mirinda.

"You come with me, clever!"

Ji Longcheng brought Da Clever to the playground, and with a wave of his hand, tens of thousands of corpses of special infected people piled up in the playground, and the air was filled with a disgusting smell of blood and rancidity, and there were hundreds of thousands of zombies killed by Ji Longcheng, and he liked to chase and cut after special infected, because special infected people evolved faster, their strength was stronger, and they were a greater threat to humans.

"How many can you make?"

"Three thousand bottles!"

This amount is much less than Ji Long Cheng imagined.

"All crafted into Evolution Elixirs!" Da Ming listened to Ji Longcheng's words, and almost cried, this will be done until the Year of the Monkey.

Ji Longcheng also felt that his arrangement was a bit excessive. The corpses of these special infected people are very dangerous, if they are used by people with intentions, Qinglong Town is likely to break out again Resident Evil, the current weather is still a little hot, these corpses will not be piled up for long, and they will decompose.

"Let Wei Zhuang send two Ice Awakened Ones over, and bring those Awakened who are old and frail and unwilling to fight."

To deal with these corpses, it must be handled by the awakened, ordinary people interfere in the processing of the zombie brain, if you are not careful, you will be invaded by the zombie virus and turned into the walking dead, Ji Longcheng can't take this risk. What's more, with such a large amount of potion extraction, even if Da Cleverness is a dragon hybrid, it is not enough, Ji Longcheng suspects that Da Clever, a hybrid, will focus all his strengths on intelligence, and other aspects will appear mediocre.

The awakened people sent by Wei Zhuang arrived soon, there were more than 20 people, these awakened people were either old and frail, or they were too timid, they didn't want to fight, the mud couldn't support the wall, Wei Zhuang didn't bother to train them, and it was easy to throw them directly to Ji Longcheng.

The old man headed by him, with a young face and crane hair, is short, giving people a kind attitude, he should have passed his old age, but he has a good way to maintain his health, and it seems that his spirit is still very good, this old man is the first to awaken the ability of the awakened person, he and Ji Longcheng have a relationship, it is the wood ability, Yuan Shang.

Ji Longcheng solemnly entrusted the research institute to Yuan Shang, there are a lot of dangerous items here, Da Cleverness is usually not very reliable, someone must be responsible here, think about it, it is better to hand it over to Yuan Shang, who is experienced and veteran.

"In the future, the highest vigilance here, the potions produced must be kept strictly secret!"

Ji Longcheng and a group of soldiers gave orders, including the usual precautions.

This potion is intended to be used as a special reward to reward brave warriors in battle, or to survivors who have made outstanding contributions, and will not be added to the item exchange list of Qinglong Town for the time being.

A few special infected people, in order to extract a bottle of evolution medicine, is still more cherished, ordinary awakened people, one-on-one heads-up after encountering special infected people, are very likely to overturn, patience for pain, mastery of combat skills, may affect the balance of victory, battle, is not the addition, subtraction, multiplication and division of panel attributes, ordinary awakened people lack combat experience, except for the fierce people in the sky, generally not the opponent of special infected.

Of course, Ji Longcheng can't be regarded as an ordinary awakener, with him splitting the wind and thorns in front of him, exchanging the heads of special infected people for evolution potions, it is enough to survive until ordinary awakened people pass the novice period, a gathering place, whether there is top combat power or not, the impact is multifaceted.

After dealing with this matter, it is already afternoon, Qinglong Town is still engaged in construction, dusty sky, at this special moment, the survivors do not have a lunch break, they must work overtime to raise the wall, only in this way, can they get enough safe shelter before the corpse tide comes, any slack now, may be killed in the future.

According to the planning of Jilong City, Qinglong Town will cast three city walls, each city wall must be ten meters high and three meters wide, and there is a road for people to walk above the city wall, which is convenient for defending the city. On the city wall, every ten meters, there are defensive turrets, which is considering that there will be flying zombies in the future, and the soldiers have no danger to defend on the city wall, and the city wall will not be breached. In addition to this, the city gate is built with an urn city, and the zombies have no wisdom, so they can introduce it into the urn city and set it on fire.

This city, Jilong City was built very large, including most of the Qinglong Valley, after completion, it was more than enough to accommodate millions of people, and its grandeur was matched by a terrifying amount of construction. The construction of 300,000 people is not enough to lay the foundation of the innermost wall.

The castle was inspired by the anime "Attack on Titan", in which the 145th King Fritz, who was tired of war, led some of the Eldians to move to Parady Island, and built three high walls with thousands of oversized giants to resist the attacks of the giants, and named them after the three daughters of the original King Fritz and Yumir Fritz: Maria Fritz, Rossi Fritz, and Sheena Fritz.

These three walls, the first wall of Mary, the second wall of Rossy, and the third wall of Sheena, played a role in the battle between humans and giants, although they were still breached by giants.

In Attack on Titan, in 845, a super-large giant suddenly appeared outside the walls of the Higanshina district and kicked through the outer gate of the Higanshina district, causing a large number of giants outside the wall to begin to pour into the Higanshina district through the breached outer gate. As a result of this sudden attack, the unsuspecting inhabitants and legions in the area were eaten by a large number of giants that poured in in an instant, and the casualties were heavy.

Immediately afterward, the armored giants suddenly appeared and smashed the inner gate of the Higanshina district, and a large number of giants poured into the wall of Mary through the Higanshina district, and the wall of Maria was completely breached. Refugees from the Wall of Mary and its four urns poured into the Walls of Rossi from all directions, and humanity lost a third of its territory, and the Walls of Rossi became the front line of humanity's struggle against the giants.

The power of the nine giants, Ji Long City is far inferior, and the zombies are even more unbearable, the three-meter-thick and ten-meter-high city wall, the tank can't hit it even if it hits its head, in fact, the zombies also have a tactic, that is, stacking Arhats, relying on the number, and accumulating the corpse tide to the point of being equal to the city wall, in the "World War Z" movie, the zombies actually ripped off the helicopter flying in mid-air by stacking Arhats, which is no longer terrifying.

In the planning of Jilong City, he divided the city into three parts, the innermost is the residential area, the second ring is the industrial area, and the outermost third ring is the production area.

In Attack on Titan, the inhabitants living outside the walls of Rossi are the most dangerous and the worst, working hard in exchange for nothing more than the food and clothing of the nobles of the inner city, which is a typical injustice and class antagonism. Ji Long City hated these and would never use the lives of the survivors as a bargaining chip to grab and exploit their interests.

All the survivors will live in residential areas, the industrial areas are responsible for the production of weapons and tools, and are not inhabited, and the production areas are also responsible for growing crops and raising animals, and these two areas are only entered by survivors when they are working, and they are not inhabited during normal times.

Ji Longcheng hopes that everyone in the last days will be well......
