Elf science, I created a new generation

Soon, thirty pairs of wild animals gathered together.

It has to be said that there are many kinds of animals in Beishan, Yunhai City.

Tiger, leopard, black bear, gray wolf, fox, sika deer, roe deer, deer sable, hooded crane, white-naped crane, oriental white stork, golden eagle, red-crowned crane, yellow-breasted bunting, black grouse, musk deer, moose...

Anyway, all the unexpected animals that Ye Feng thought of came, and they were all wild animals.

【Ding!Congratulations to the host for completing the upgrade task of Shop No. [-] and unlocking the sixth alien space. Shop No. [-] has been changed into a post-apocalyptic ranch, and the absolutely safe area has expanded to [-] square meters. 】

Ye Feng was startled. It seems that he was lucky. Before the apocalypse came, he got a doomsday ranch in advance, that is, a large doomsday shelter.

"Master, this...?"

Xanadu looked at the changed yard and the place outside the yard.

What happened in the end?
Xanadu didn't understand the power of the system.

"Take charge of this place well, it will be of great use in the future."

The road has to be taken step by step, otherwise, if you take too big a step, you will easily fall into trouble.

Ye Feng flipped through and found a Doomsday Ranch Handbook. He read it first, and the content inside moved him.

"Xanadu, this manual is for you, study it carefully, and call me if you don't understand anything."

"it is good."

Xanadu met Ye Feng is its blessing, it can make it grow up quickly, or grow up safely.

It flipped through the manual, but a card fell out.

Ye Feng thought that the card that landed was an ordinary card, but when he picked it up, he found it was a strange card.

[Dave's courtyard. 】

???

Ye Feng was a little shocked. Dave had heard of it, and so had Dave's courtyard.

Isn't that Dave in the famous Plants vs. Zombies?

With a thought, Dave's yard merged with the yard of No. [-] shop.

【Ding!The host successfully activated the special tower defense card - Dave's courtyard. 】

[Task Requirement: Assist No. [-] Store in resisting attacks from ten waves of zombies. 】

[Task Reward: Complete the unlocking of the seventh map of the alien space and get the SSS-level mysterious treasure chest. 】

[Task time: three days. 】

[Note: Dave's courtyard is a god-level prop, coveted by monsters. 】

Ye Feng was overjoyed, this task is relatively simple.

But when something goes wrong, there must be a demon.

Strange things happened one after another, Ye Feng didn't think it was a coincidence.

It even felt like someone had set up a script for him in the dark.

As long as each piece is completed without any regrets, it will be heaven.

Ye Feng is helpless, his current strength cannot collide with the forces behind him, so he can only follow suit.

Is it all the system's fault?

Thinking of this, Ye Feng couldn't help but shudder. If the system is really doing something, then he basically has no solution and can only follow suit.

【Ding!Congratulations to the host for triggering a coupon for Dave's small courtyard experience, which allows you to experience the fun of tower defense cards in advance. 】

There was an extra card in Ye Feng's hand, on which was written the words "experience coupon", which was very simple.

Try it out.

Ye Feng directly used the experience coupon.

In an instant, the scene in front of Ye Feng changed a lot.

Dave's courtyard appeared in front of him.

In front is a long lawn, next to the lawn is loess, and behind it is a house.

The four walls became three, and the front wall was just a low fence. Even the lowest level wild monsters could break through that fence.

it has started!

The moment Dave's courtyard opened.

Countless zombies appeared, biting the fence and breaking into the courtyard.

The first is a few zombies rushing into the yard.

At this time, there was a light screen in front of Ye Feng.

The top one is the plant bar, and there is only one pea shooter card in it.

Pea shooter.

Attack: 20.

Light energy spent: 100.

Cooldown: 7.5 seconds.

Durability: 300.

Range: One full line straight ahead.

Shooting interval: 1.4 seconds.

Function: Attack zombies by launching peas.

Plant Characteristics: Green plants, pea family.

It is daytime now, you can absorb 5 points of light energy from solar energy for 25 seconds, and accumulate 150 points of light energy in half a minute.

Ye Feng immediately exchanged for the pea shooter and placed him in the third-to-last position on the lawn.

Click!Click!
By this time the zombies had broken into the yard and rushed towards the peashooter.

Strange to say, all wild monsters will walk along that lawn.

Coincidentally, the direction of the pea shooter's shooting is also this straight line of the lawn.

Bah!
Bah!
Bah!
……

The front zombie was killed by 6 pea bullets and dropped nothing.

In 1 minute, Ye Xiao exchanged for three pea shooters, and the three pea shooters fired pea bullets together, killing zombies very quickly.

The first round of zombie attacks lasted only half an hour.

Collect a total of 9000 points of light energy.

Exchanged 5 pea shooters, consumed 500 points of light energy, and left 8500 points of light energy.

【Ding!The host can consume 5000 points of light energy to upgrade Dave's courtyard. 】

Without hesitation, Ye Feng spent 5000 points of light energy to upgrade Jason's courtyard.

【Ding!Dave's courtyard, level 2 upgraded. 】

In an instant, two more lawns appeared in the yard, and a plant card sunflower appeared in the plant column.

sunflower.

Cost: 50 light energy.

Durability: 300.

Cooldown time: 7.5s.

Sunshine Production: 25.

生产时间：第一次5～10秒，之后每个23~25秒，每次生产一颗中等阳光（25阳光）。

Plant characteristics: yellow plants, endless sunlight.

【Ding!The second round of wild monsters will attack the small courtyard in 10 minutes, please prepare for the defense of the host. 】

It has to be said that the current world is a bit chaotic, as long as there are foreign worlds integrated into the world, there will be collisions.

Once the two worlds collide, a large number of monsters will invade the earth.

The second wave of zombies has arrived.

Ye Feng carefully checked the contribution of the first wave of zombies.

Kill 120 zombies and get 1200 points.

The second round of wild monsters came soon, and this time the number of zombies had at least tripled, including helmeted zombies.

But when it comes to Ye Feng, it's nothing more than recruiting more pea shooters to get rid of all the zombies.

The vanguard officers were still ordinary zombies, they rushed into the lawn waving their arms.

There are three lawns in the yard, and the zombies are divided into three teams and rush into the yard.

Ye Feng smiled. He now has a lot of light energy. First, he placed a pea shooter on each lawn, starting from the third last position.

The last two positions are for sunflowers.

Although there is a cooling time, the formation was arranged in less than 2 minutes.

There are two sunflowers and one peashooter on each lawn.

Next is the time to eat melon seeds and watch a show.

As long as you keep the peashooters in check and gather sunlight, everything is fine.

The zombies set foot on the lawn one by one, and fell down one by one, turning into test points.

Helmet Zombies start playing.

This kind of helmet has a certain degree of defense, and can withstand a few more pea bullets.

But with the pea shooter covering three lawns, the ending is irreversible, and all the zombies are brought down.
