Biochemical plant upgrades, only the manufacturing function is turned off.

The entire upgrade process takes five hours, that is to say, in these five hours, Lu Chuan is unable to make any zombie products, but he can use his vision to view some information.

"Grandma's, it's finally upgraded."

Staying in the boss's office, Lu Chuan exhaled lightly, with a smile of anticipation on his face.

Once the upgrade is completed, the changes will be doubled and the benefits will be infinite. It can be said that after every level increase, Lu Chuan's strength will have a qualitative change.

Looking at the time, Lu Chuan was looking forward to it, but he was not in a hurry.

After thinking about it for a while, Lu Chuan took out a set of virtual glasses from the storage space and activated them after putting them on.

The virtual technology in the last days has matured, but now AR technology has not yet been integrated with virtual technology, if there is no end times, I believe it will only take a few years to complete this leap.

Once integrated, it is a qualitative leap.

It's a pity that the advent of the end times has destroyed all this, and the integration of technology, only halfway through, was swept away by this disaster, and no one will study this one anymore.

Five hours, to pass, can only play a game.

Speaking of which, Lu Chuan's age is actually the age of a young man, and playfulness is the essence.

When he graduated, the burden of his family made Lu Chuan give up his greed for fun and devote himself to work. It's a pity that it's really not easy to get a better job in the city after studying civil engineering. There was really no way at the beginning, so Lu Chuan finally chose the job of supervision.

The work of the supervisor is indeed a little idle, if Lu Chuan gives up the principle, it will not be a problem to earn four or five thousand a month.

But Lu Chuan, who has just entered the industry, has just graduated from college and has not yet experienced the cruelty of this society, so he naturally did not join the same stream, and received 3,000 yuan every month, and has been working diligently.

Working hard, there is less time to play, plus there is no money, and even the computer is from the previous college days, and with today's game configuration, there are fewer games that can be played.

Virtual games, completely and modern games, are heaven and earth apart.

It is no exaggeration to say that as soon as virtual technology comes out, the authorized use of games alone is enough to create a company that is even larger than Microsoft and Apple. This is not an exaggeration, look at the network, in the early days, it was completely relying on games as a growth point, how many gamers are there in the world?

Virtual technology can also be extended to other industries, and it can be said that the achievements of this company will surpass Microsoft and Apple.

There are a lot of engineers in hand, so it is a little difficult for them to develop new games and equipment, but it is no problem for them to debug existing games and equipment to a certain extent.

Like Lu Chuan's current virtual glasses, it is a medium, connecting people and the virtual.

The difference is that this virtual glasses are professionally born for games, and there are a large number of games built into them, but now there is a lack of network, and what Lu Chuan can play is just a stand-alone game.

This pair of virtual glasses, which integrates a large number of electrons in the frame, can emit a kind of electronic waves synchronized with brain waves, which are used to connect human neurons. After the neuron is connected, it synchronizes with the brain.

Glasses are part of the brain, which is like a human arm, controlled and directed by the brain, and so on.

When you hold something, the brain gives instructions and the hands start executing. And virtual glasses, that's it, when you want to, you can operate it.

This kind of technology has been studied in modern times, but the results are ...... It can only be said that in theory, the manufactured equipment can only be used for experiments, and there is still a long way to go before it can get out of the laboratory.

Don't underestimate this technology, it is used in many industries, beyond imagination.

Once combined with AR technology, the most important thing is its military application. Think about it, when operating a tank, you can use this brainwave technology, and the speed of the reaction will be doubled, and the effect produced by combining with AR technology is leapfrogging.

A small pair of glasses, it represents the maturity of virtual technology, you must know that before the end of the world, virtual technology is also from the helmet type, slowly developed into glasses and so on.

As long as there is a technological breakthrough, it is only a matter of time before it becomes miniaturized.

After putting them on, the glasses were activated, the brainwaves were synchronized, and in an instant, a huge space appeared in Lu Chuan's mind. When Lu Chuan's mind sank into it, there was only this one space left in the whole world.

Lu Chuan, who has already experienced it, is still full of curiosity.

Skillfully clicking on one of the stand-alone games with his mind, Lu Chuan entered a fantasy world again in the next moment. It's like a dream, it's like entering a dream.

But virtual games are games after all, and it can't be done the same as in reality, like monsters' health bars, some panels of characters, etc., you still have to have, and it also reminds you all the time that this is just a virtual game world.

…………

Lu Chuan set the time, five hours, in the virtual game, Lu Chuan didn't feel the loss of time at all, it was already over.

The alarm clock rang, and Lu Chuan had an idea and quit the virtual game.

Taking off the virtual glasses, because they are connected to neurons, when they are disconnected, Lu Chuan is a little uncomfortable. After all, Lu Chuan is not used to it, and it is difficult to have no impact.

Like 3D games, some people will feel nauseous and want to vomit when they play it.

What catches my eye is still fiery red.

This is a kind of reminder when the zombies attack, and it will remind you for a full month, so that you will always know that this crisis is coming.

Every time he saw this kind of red, Lu Chuan would tense his nerves.

A series of prompts appeared in Lu Chuan's mind, representing the completion of the upgrade of the biochemical plant.

The upgrade of the fourth-level biochemical plant was completed.

Level 4 product map unlocked.

The expansion of the negative 6th and 7th floors has been completed, and the addition of the fourth floor has been completed.

The radiation range of the holographic projection of the fourth-level biochemical plant has been increased to 8 km.

The storage space has been extended to 16 meters.

Unlocks the metal carry limit.

Biochemical Plant Level Upgrade Rewards have been distributed.

What is a qualitative leap? Let's not talk about the product map unlocked, and don't say that the underground negative layer is unlocked to the sixth or seventh floor, the direct qualitative leap is actually the radiation range, that is, the field of vision has reached 8 kilometers.

The storage space has been expanded to a huge space with a side length of 16 meters.

The side length of 16 meters is enough to fit a trailer in.

What really made Lu Chuan feel ecstatic was actually the restriction on metal carrying, which also meant that he could finally use the storage space as he wanted, and he could have no scruples.

With the unlocking of this limit, Lu Chuan can use his imagination without limiting his transformation of zombies. will no longer restrict his hard manufacturing behavior, and Lu Chuan will no longer be afraid of the stronghold.

The unlocking of this function is called real timeliness, and for defense, Lu Chuan has become confident.

The storage space has become larger, which has increased Lu Chuan's carrying capacity several times, and some things that could not be carried before can now be carried as much as he wants.

The metal restriction is unlocked, which means that the arms can finally be circulated in two worlds.

In the previous last days, Lu Chuan had no way to bring them to the modern times, and the guns in the modern times also had no way to carry them into the last days. More can only be stored inside, not taken out.

Now that this restriction has been unlocked, Lu Chuan's confidence is there.

"Cool!"

Lu Chuan grinned, the benefits of being able to use weapons were too many.

The weapons in the modern era can be brought to the end of the world, and the weapons in the end times can be carried to the modern day and handed over to the female spear gods for use. With this function, the female spear god and their weapons will not be controlled by people.

The three-dimensional space with a side length of 16 meters, not to mention tanks, even fighters can be carried over.

Think about it, what it would be like to have a tank and an airplane in your hands?

The second thing to look forward to is the four-level product diagram structure.

Before the upgrade, you can't see it, but after the upgrade, you will unlock the product structure diagram, which can let you know how many products this product line has. The first product, on the other hand, will be greyed out and in the range that can be unlocked.

This is a fourth-level product, a fourth-level zombie, so it goes without saying how perverted it will be.

The third-level licker is already so strong, what will happen to the fourth?

In Lu Chuan's mind, the technology tree appeared.

"Five products?"

Looking at the product line above, Lu Chuan's eyes widened, there were only two products at the first level, ordinary zombies and zombie dogs; At the second level, there are only three products, the Alien Zombie, the Furious One, and the Swift One; At the third level, there are also only three products, the Licker, the Cerberus, and the Tyrant.

Now in the fourth level, it has increased to five products.

When Lu Chuan locked the first product, a line of information appeared: Chaser: 0/10.

There was not too much introduction, but it shocked Lu Chuan's heart, the pursuer is definitely a famous existence. Its classic shape is also on top of the tyrant's initial test type, which is the real biochemical weapon after the demon reform.

And the pursuer, Lu Chuan has been in this city for so long, and he has never seen any of them.

As you can imagine, it is very difficult and takes a long time to unlock the pursuer, and it is not possible to unlock it if you want to. Like this kind of high-level zombie, each one is difficult to unlock.

Except for the Chaser, the second product picture is black, and there is no information of any kind, so you don't know what kind it is.

It was only level four before the pursuer appeared, which was expected, but also unexpected. Unexpectedly, it was because of the appearance of the tyrant trial type at the third level, and with the status of a pursuer, it was indeed going to appear at the fourth level.

But the problem is, the status of the pursuer, in Lu Chuan's familiar biochemical knowledge, is also one of the top zombies, and it can be unlocked so quickly?

So, what kind of zombies will be unlocked in the biochemical factory in the future?

Just this technology tree and product map revealed too much information to Lu Chuan, and it is not difficult to speculate from this point that the next products of the biochemical plant will be shockingly powerful.

"Will the pursuer, as in the setting, have thermal weapons?"

Lu Chuan pondered this question, and before he saw the pursuers, everything was difficult to say.

The fun would have been great if the pursuer had a weapon, and with thousands of rounds of bullets on it, it was a blast of excitement when fired with a multi-barreled Gatling.
