A construction site outside a biochemical plant.

Today is a rare sunny day, the scorching sun is in the sky, and a group of zombies are busy.

The position map designed by Zhao Beijiang and them was quite perfect in Lu Chuan's opinion. Although the construction did not meet the requirements, Lu Chuan was already satisfied.

The position was cut in design, and the front Zhao Beijiang and they advanced into the street.

In this way, when the zombies appear on the street, they will enter the position through the maze-like entrance on the street, and then enter the maze-like position.

The labyrinthine position has many hollow-shaped routes, and as long as the zombies come in, under their thinking, they will only go all the way forward, and will not think about climbing.

On the route, some concave surfaces are designed to hide the zombies, and when the time comes, you only need to keep out the knife and kill the zombies passing by. Similarly, the route also takes into account the problem of zombie corpses, and when the time comes, it can only be Lu Chuan who controls the rhythm of zombies, so that it will not be blocked in one place, so that the attacking zombies will pile up a mountain of corpses.

The construction of the entire position is very huge, which also fully takes into account the defense problems in the later stage.

And against the air, there is no way at present, because once a flying zombie attacks, this problem is serious, with the architectural form of a biochemical plant, it is really difficult to defend from the air.

The arrangement of anti-aircraft firepower for the biochemical plant is also a thorn in Lu Chuan's heart, and with his current conditions, there is really no way to get this kind of anti-aircraft firepower to arrange.

At this time.

Lu Chuan was standing in front of the tyrant who had been cut into corpse sticks, and when this tyrant saw Lu Chuan, he struggled frantically, opened his mouth, and let out a roar.

"Roaring ......"

It has been a long time since this tyrant was tied here, but the other party had no limbs, and he still stayed here alive, although it was chained here, but it did not have a trace of decadence.

Well, to say decadent to a zombie is to exalt them.

In Lu Chuan's hand, under a flip, a javelin appeared, which was made of alloy and had a lot of weight. After the genetic enhancement, under the great force, with this very heavy weapon, the power will be even more prominent.

"The tenth fragment is you."

Lu Chuan muttered, there is no mercy in it, and there is no need for any mercy in it for a tyrant zombie.

I saw Lu Chuan's arm muscles bulging, and under the explosive force, he threw the javelin violently.

Such a close distance, coupled with Lu Chuan's third-level genetic enhancement strength and control, allowed the javelin to hit the tyrant's head. Without limbs, it is actually at the point where it has no way to hide.

The alloy javelin, there is no need to doubt its hardness, under Lu Chuan's huge force, with a "poof", it directly sank into the tyrant's head and nailed the tyrant to the ground.

Killed by one blow.

The powerful tyrant, when he was cut into a corpse stick, could not withstand Lu Chuan's blow, and he was killed.

"Ding, harvest a tyrant shard."

"Ding, the Tyrant is unlocked."

"Biochemical plant upgrading

Two beeps, one after the other.

Lu Chuan, who had long known that this was the result, still couldn't help the excitement in his heart.

Glancing at the dead tyrant, Lu Chuan walked over and pulled out the javelin that had pierced its entire head. With the sound of a prompt, Lu Chuan didn't need to be guarded, because this tyrant was already 100% dead.

The javelin was pulled out, and a stream of fluid with brain pulp gushed out of Ruoda's brain.

Lu Chuan flicked the javelin, wiped it, put it into the storage space, and turned to enter the biochemical plant through the entrance.

Biochemical plant owner's office.

Lu Chuan sat on the comfortable boss chair and relaxed.

Tyrant unlocked, now it's time to check the harvest.

The mind summoned the tech tree panel, on which the gray tyrant icon had been lit up, which represented the unlocking of the tyrant. The icon of the tyrant is a half-side photo, half of the tyrant's face, and its alienated bone spur arm, just at a glance, people can feel its fierceness.

Tyrant Trial Type: The first tyrant has a serious decay of his own, exposing huge organs, his right fingernail has become huge and sharp, and his left hand has evolved into extremely sharp and huge claws, more like a sharp blade. The power is so strong that a small car looks like a toy in its eyes.

The strongest zombie in the third-level product line, cost: 500,000.

Everything was the same as Lu Chuan expected, the cost was really 500,000, which invisibly relieved Lu Chuan. There is a big gap in my own funds, and if the manufacturing price is expensive, it is not easy to mass production.

Fortunately, the cost is only 500,000.

It's not surprising to think about it, the tyrant is strong, but it's only the first generation of tyrants, it's extremely rough, and its size is destined to lose a lot of things, such as agility and speed.

A tyrant who is not sensitive, its power is amazing, but as long as you go around it, you can make it never hurt you.

There are too many zombies that are more powerful than the tyrant's trial type, such as the tyrant T002, such as the pursuer. Or the type of zombie among the flying zombies that even Lu Chuan can't name.

Don't forget, the tyrant trial type is just a zombie of the third-level product line.

Further up, there is a four-level product line.

The first tyrants, in fact, were not very difficult to deal with in the eyes of humans. Its organs are exposed, which makes it easier to get hit in these organs, slowing down its abilities.

Not fast speed, tall stature, if a big head, in front of a sniper rifle, just a target.

Come to think of it, the enthusiasm at the beginning has faded a lot.

"No matter what, a tyrant is a tyrant, and when used well, the effect is far greater than that of a licker."

Lu Chuan grinned toothily and quickly thought about it.

The cost of 500,000 is destined to be on a large scale for the first generation of tyrants.

The five-meter-tall tyrant trial type, when it appears in hundreds or thousands, this scene, as long as you think about it, can make people's blood boil. And this scene will definitely make people afraid.

Biochemical Factory Level 4: Manufacture 30 Tyrant prototypes to start the Level 4 Biochemical Factory upgrade.

At present, Lu Chuan's funds are limited, and after thinking about it, Lu Chuan finally plans to make thirty of them, as long as the conditions for opening a fourth-level biochemical factory are met.

Thirty is fifteen million.

Originally, there were only more than 70 million funds, but after deducting 15 million, not even 60 million, only 57 million funds remained, if Lu Chuan couldn't find a way, these funds would not be able to support for long.

The tyrant is made, much slower, thirty takes almost an hour.

The product line of the fourth-level biochemical plant, when it is not opened, is not visible, but it is black. However, for the fourth-level biochemical factory, Lu Chuan is still full of expectations, the third-level products are so good, and the fourth-level ones will definitely be stronger.

Lu Chuan also has a certain understanding of the power structure of this world.

What I see so far is definitely the tip of the iceberg, and among the survivors, there will definitely be stronger ones. Zombies can evolve, but people can.

In the unknown survivor base, there will definitely be a human presence that is beyond imagination.

An hour, not too long.

Lu Chuan has been sitting in his office, calmly waiting for the tyrant to appear.

With the previous experience, Lu Chuan also knew that as long as the tyrant was completed, it would be the time to start the third crisis. Like last time, due to insufficient preparation, I almost didn't protect against zombies.

Now it is different, Lu Chuan can be said to be strong in his hands, and the zombies that can be mobilized have broken through to nine thousand.

What kind of concept is this?

Nine thousand zombies, if they really come back, they can completely fill a street and form a sea of corpses that is not a small scale.

It's just that among these nine thousand zombies, ordinary zombies account for too much of it, and their combat effectiveness can only be said to be average.

But Lu Chuan is confident, and with the strength in his hands now, it is enough to bulldoze the stronghold by force. Swift, Enraged, Alienated Zombies, Lickers, Cerberus...... This series of zombies all belong to alienated zombies, and their number also accounts for a large proportion, which is already a force to be reckoned with.

An hour passed quietly.

"Thirty tyrant prototypes have been made."

At the product exit stand, thirty tall tyrants appeared on it, and then stood in front of Lu Chuan.

I didn't think that the tyrant's height of more than five meters was anything before, but now when he stood in front of them, the feeling of depression he felt made Lu Chuan swallow his saliva.

His height of more than 1.7 meters is completely disproportionate compared with more than 5 meters.

In the naked, exposed skin, it is indeed very seriously rotten, some organs are exposed, the tyrant is a humanoid too, these organs make Lu Chuan look a little uncomfortable, and his stomach twitches.

Lu Chuan is not a short time in this last days, but in front of the tyrant, he is still a little uncomfortable.

For the first time, Lu Chuan watched the tyrant so closely.

There was no touch, but Lu Chuan could feel the explosive power that the tyrant was full of. Especially its alienated arms, every muscle, like steel, and the bone blades alienated from its nails, completely unknown what kind of material they are made of, are extremely sharp and hard.

A row of thirty tyrants juxtaposed is truly spectacular.

Standing in front of the tyrant, Lu Chuan thought a lot, but the next moment, a violent alarm sounded in his mind.

Endless red appeared in Lu Chuan's eyes.

"Really ......"

Lu Chuan, who had been prepared for a long time, showed a flat smile. I don't know why, the arrival of the zombie attack made Lu Chuan relaxed, at least he didn't need to guess when he came out all day.

Crisis: Boost the Biochemical Factory, which passively attracts certain zombies with special perceptions, and these zombies of the same level as the Biochemical Factory will target the Biochemical Factory to attack. There is a small chance of a high number of zombies in the Chemical's Tier 1 to Tier 2 Zombies.

Success Condition: Keep them out of the Alloy Walls of the Biochemical Factory, so that none of the zombies can touch the walls. Reward a random item from an existing product in the Biochemical Factory or an additional Marketplace.

Failure Condition: The zombie touches the alloy wall of the biochemical factory. penalize and lower the biochemical plant by one level.

Immediately, a line of information came to mind.

Zombie Strike Countdown: 29 days, 23 hours, 59 minutes and 37 seconds.

Compared to the seven days of the first time and the fifteen days of the second time, the preparation time this time was doubled, reaching one month of preparation time.

Lu Chuan didn't like it, the more time he had to prepare, the more time he had to prepare, it meant that this zombie attack was far from being as simple as he imagined. In Lu Chuan's heart, he was even ready to appear as a first- or second-level zombie.
