"Back to the biochemical plant."

After unlocking the corpse dragon, Lu Chuan was naturally excited, this was a kind of zombie that he had been looking forward to for a long time.

For a long time, the corpse dragon rewarded by the biochemical factory is its own mount, and its weightiness is naturally needless to say, and it has helped him for a period of time.

In his own vision, the corpse dragon also occupies an indispensable position.

Now the corpse dragon is finally unlocked, it can be said that it has taken a long time, and it is the type that takes the most time to unlock zombies so far.

With Lu Chuan's order, the huge bloodthirsty claws converged again, and then protected Lu Chuan's departure.

The sound below, Lu Chuan ignored it, and when the time came, they would naturally lose their effect, and then these zombies would fall into a state of scattered and free wandering.

Almost when Lu Chuan turned his head, suddenly, everything he saw turned blood red.

"Grass, I really let myself guess it."

This kind of blood red is very familiar to Lu Chuan.

The zombies attacked, and the moment he unlocked the corpse dragon, it was finally turned on again. Lu Chuan had this kind of preparation before, after all, it had been too long to enter the fifth-level biochemical factory this time.

If you change the previous pattern, you should have started zombie attacks a long time ago.

Lu Chuan guessed the pattern a little bit, for example, after he needed to unlock the third product by himself, or if he hadn't unlocked it for a long enough time, it would be like a zombie attack.

No matter what the law is, Lu Chuan is already mentally prepared for its arrival.

Especially now, the moment he unlocked the corpse dragon, Lu Chuan had a premonition.

Who knew that this kind of premonition would be so accurate, and he unlocked it, and before the person returned to the biochemical factory, it began to appear, and there was a feeling of impatience.

When zombies attack, a constant warning will be formed, and anything you see will be blood-red.

"Dismiss the alert."

Lu Chuan, who had long been accustomed to all this, immediately chose to turn off the alarm.

Just subconsciously, Lu Chuan's eyes were placed on the upper left corner of his eyeliner, and it generated a small countdown time within his eyeliner.

Zombie Attack (Active) Countdown: 59 days, 23 hours, 59 minutes and 07 seconds.

This time, the preparation time was 2 months, which is a very long time. But the longer it is, the more ferocious it means for Lu Chuan.

Lu Chuan just glanced at it and didn't notice some small changes this time, such as the word "initiative".

Moreover, this time, the alarm appeared before the biochemical plant was upgraded.

…………

Biochemical plants.

The first time Lu Chuan returned, it was already dark. In the dark night, it was very dangerous outside, but fortunately now I am just hiding inside the biochemical factory, not outside.

Let the bloodthirsty claws find a place to lurk, and Lu Chuan returned to his boss's office.

Sitting on the comfortable boss's chair, Lu Chuan opened the product tree for the first time.

I only saw the third product in the fifth-level product, the corpse dragon, and the shadow that had been dim before was finally lit up now. A hideous dragon head, which looks terrifying and mighty, has the feeling of a combination of the dragons of the East and the West.

Lu Chuan's mind was placed on the icon, and information about the corpse dragon suddenly appeared.

Corpse Dragon: A fifth-level product, a scientific research institution extracted the genes in ancient dinosaur fossils and conducted genetic research. In the study, the human test subject who was injected with this kind of clone cell, after being infected by the virus, was alienated into a dragon-shaped zombie, and the manufacturing price: 1 million.

The simple information points out the origin of the corpse dragon and its past and present lives.

No wonder this product is somewhat similar to dinosaurs, it turned out to carry the genetic cells of dinosaurs, but this research institute has no way to clone dinosaurs, only can clone some cells that are not like three, and then through the injection of the human body, to achieve the effect of making humans stronger.

Unfortunately, a study like this one is a big brainstorm, but it is difficult to succeed.

How could the cells of dinosaurs be compatible with people, it must be full of rejection.

Presumably, the people who were experimented with are estimated to be absolutely miserable under this kind of rejection. Of course, there is nothing human about the experimental subjects, and it is not under their consideration to live painfully.

In the last days, the virus infected these experiments, and thus evolved the corpse dragon.

It's hard to imagine that such a huge corpse dragon could have evolved from humans. Lu Chuan had seen its skeleton before, and it had nothing to do with people at all, the problem was that it really evolved from people.

I have to say that the bull fork of this virus is really like God, which can be created out of nothing.

The virus is cross-infected, for example, there is the formation of a corpse dragon, and the virion emitted by the corpse dragon carries this kind of infection, and through the infection of this kind of corpse dragon, it will spread, so that some zombies have evolved into corpse dragons.

Otherwise, relying on a small number of test subjects in the laboratory, it would be impossible to have so many corpse dragons.

After figuring out the past and present life of the corpse dragon, Lu Chuan also sighed at the horror of the virus. At present, in the last days, the virus is still infected, but almost all survivors have immunity, so they will not continue to be infected.

The cost of 1 million, Lu Chuan was mentally prepared, and when he strengthened the corpse dragon, he already knew its price.

Now that it's unlocked, of course, it's manufacturing.

"Make a thousand corpse dragons."

One billion was smashed out, but Lu Chuan didn't have any heartache, this was already within the scope of his plan. Directly making a thousand corpse dragons in one go can be regarded as a big deal.

Under Lu Chuan's instructions, the manufacturing workshop began to enter the manufacturing process.

The manufacturing time required for a thousand corpse dragons reached four hours, which means that the manufacturing speed of one hour is two hundred and fifty, which is not slow.

Looking at the manufacturing progress bar, Lu Chuan stretched his waist and showed a satisfied smile.

After the corpse dragon, Lu Chuan found that there was no fourth product, which also means that as long as this batch of corpse dragons is manufactured, the biochemical factory will be upgraded and upgraded to a sixth-level biochemical factory.

For the sixth level, Lu Chuan is also full of expectations, according to the previous practice, everything related to the biochemical plant will be doubled. For example, storage space, such as the horizon range.

"The storage space is further improved, and it is a cube space with a side length of 32 meters."

If this is the case, it would be an exaggeration, with more than 30,000 cubic meters of space, dozens of tanks can be stuffed, after all, the space can be stacked.

The current space, Lu Chuan already felt that it was enough, after all, he didn't want to put any warships or the like into the storage space.

"When the corpse dragon is made, we will know."

Lu Chuan smiled and returned to the modern era.

Tonight, I made an appointment with Shi Ruoyu for dinner, and I couldn't let her wait for a long time.

Thinking of her current triangular relationship, Lu Chuan still has a headache, Shi Ruoyu has now entered the internship period, but she chose a local company for internship, and did not come to Baichuan Guihai Company, otherwise Lu Chuan really doesn't know how to deal with it.

Wait until she graduates......

It's a headache to think about, and it seems like it's time to fix it.

Fish and bear's paws, really can't have both?

…………

Eat, roll the sheets.

After a night, Shi Ruoyu was sent to school, and Lu Chuan plunged into the laboratory again. It is safe enough here, and Lu Chuan can enter the end times generously.

Apocalypse, biochemical factory.

When Lu Chuan entered, there was a series of prompts in his ears.

The first is the summary of all kinds of damaged and dead zombies, Lu Chuan is used to it, so he deals with these very indifferently, his eyes sweep, and he only needs to remember the approximate value.

Secondly, Lu Chuan found the prompt sound that the corpse dragon was completed.

However, it is accompanied by the prompt sound of the upgrade of the biochemical plant. The current biochemical factory is in the upgrade time, and Lu Chuan can't operate it, such as making zombies and the like.

Lu Chuan just took a look at the time of the upgrade, it was 24 hours before, and 48 hours this time.

So far, only ten hours have passed, and the upgrade will not be completed until the early morning of the day after tomorrow.

The underground floor of the biochemical factory is actually a warehouse, and all the zombie products manufactured by the biochemical factory are stored here, and it has expanded to the biochemical factory on the negative six floors, according to Lu Chuan's estimate, it is not a problem to accommodate tens of thousands of zombies.

Negative layer.

This place has been pushed by items, and the superbrain commander has been commanding the zombies here, and the quota it can command is full, and the main responsibility is actually to collect all valuable items from the city.

The superbrain commander executed it well, and tens of thousands of zombies were like art under his hands, carried out according to different processes, in an orderly manner, and there was no need for Lu Chuan to worry about it.

It's just that there are mountains of materials here, but Lu Chuan has never had time to deal with them.

Went straight to the negative third floor, and finally saw the corpse dragon.

Corpse dragons, they are standing on the negative three floors, they are like dragons, they put away their meat wings, still giving people a terrifying momentum, they are not angry but mighty, just standing, it makes people feel the oppressive force rushing to their faces.

A thousand corpse dragons, standing side by side, cover this huge space, which is visually shocking enough.

How to say it, the corpse dragon stood, with its flesh wings folded, more like a lifelike statue. If you walk between them, you will feel small.

"Tut-tut......"

One billion, with this effect, Lu Chuan is very satisfied.

Corpse dragons are very hideous, their individual combat power is very strong, and the group is ...... They are not group zombies, but when Lu Chuan lets them fight in groups, it is okay, and the attack power that erupts must make people desperate.

Imagine the overwhelming appearance of a thousand corpse dragons, this picture, God knows what the survivors below will collapse into when they see it?

"When the funds are more abundant, make 10,000 corpse dragons out, and then get 30,000 or 50,000 bloodthirsty claws, and heap people to death."

Lu Chuan grinned, although there is no way to achieve it in the short term, but it feels cool to think about it.

Lu Chuan walked in front of the corpse dragon, they were almost carved out of the same appearance, under genetic evolution, they would not change much, they were much the same.

Rows and rows of corpse dragons, they stood, not moving.

Even Lu Chuan had the illusion that they were originally statues.

However, Lu Chuan's eyes swept over their bodies, and he could see the information they were holding, and the information on them represented its simple information, such as what innate instincts it had.

EC is the code of the corpse dragon.

Lu Chuan immediately found the EC1 number of this corpse dragon, it is the first corpse dragon created, according to the rules, it will be much more than other created corpse dragons.

I only saw the first corpse dragon in the first row, with three marks of initial instinct.

"Three initial instincts."

Lu Chuan smiled, this should be the highest instinct number, it is worthy of being a product made by NO1, and it is born with the aura of the protagonist.

EC1: Divine power, thick skin, sensitive.

The three instincts are very simple, but each of them is not simple in Lu Chuan's opinion. Needless to say, the skin of the corpse dragon is already very thick, and if you give it a thick skin, it is estimated that it will take a sniper rifle to have an effect on it.

The clumsiness of the corpse dragon is compensated for by a sensitive instinct, and the corpse dragon with agility is definitely very perverted, just like a strong man, but he can dance ballet, and it is not surprising?
