After killing more than a thousand zombies, Ye Mo was satisfied, but also a little surprised.

To his surprise, his first fight two years later was much better than all the previous ones combined.

"This is the result of the improvement of strength!" Ye Mo was very emotional, after practicing Araki's divine skills, below the golden armor zombies, he relied on the dagger capital ability to slaughter.

After the battle, the soldiers had to clean the battlefield, gather the wounded together, isolate them, and prevent them from being released from others. As for the dead comrades, the heads were cut off to prevent them from being transformed, but the bodies were brought back.

The dead zombies are easier to deal with, they are all piled together, sprinkled with gasoline, and then burned.

However, because there were so many dead zombies, it took a night to burn them, leaving a pile of ashes, and the soldiers of the farm just used it as fertilizer the next day and sprinkled it on the grassland, which was regarded as a little contribution to the farm.

When Ye Mo was busy with them, he walked to the side by himself and quietly checked the changes in the system. When the others saw him like this, they thought they were feeling sad for the dead life, and they didn't bother him.

"Sunshine value: 111800!"

The first thing he saw was the change, which was a huge number, and it was gratifying. He remembered that when he used to have the most, it was only more than 10,000 points, but now there are so many. Killed more than a thousand zombies, plus some left before, to get so many sunlight points.

And then he's looking at the biggest changes to the system, and the ones he's been looking forward to for a long time.

Upgrade!

The system was upgraded from Level 2 to Level 3.

And every time the third level of the system brings new changes, this is what Ye Mo wants to figure out.

After the system is upgraded to level three, the rules for exchanging plant seeds have changed, and each seed requires three hundred sunshine, which is one hundred more expensive than before. The growth time of the plant has also changed from 20 minutes to 30 minutes, which is a little slower than before.

However, the power of the non-plant species has increased a lot compared to before, and the range of the pea shooter has reached thirty meters, the rate of fire has doubled, and the blasting power has increased by three percent; Cherry Bomb and Potato Thunder, which can now kill twelve normal zombies, double the power; The nut can resist sixty bites, and its defense is greatly improved.

The Wisdom Tree in the Botanical Garden, the changes are also gratifying. It has grown a little stronger, once a sapling, now a small tree. Although it still looks a little "slim", it is much shinier. Whether it will have new abilities, Ye Mo is curious.

The wisdom tree is a hidden plant in the system, and it does not need to be exchanged for its own appearance, saving sunlight points; Growth depends on the number of zombies killed, and it has little to do with time. And the ability of the wisdom tree, the system will not give you a hint. The last time it warned the farm soldiers, Ye Mo also figured it out by himself.

As for whether he has new abilities now, Ye Mo can only explore it by himself.

Figuring out these changes one by one, Ye Mo then looked at the plant seed interface and saw two new icons lit up.

"Big-mouthed flowers, the exchange price is three hundred sunshine value!"

"Jade hand pitcher, the exchange price is three hundred sunshine value!"

Ye Mo read it out in a low voice, and said in his heart: "Welcome to Ye Mo's world." ”

Both of these plants are Ye Mo's favorites.

"Bigmouth Flower, ignoring the zombie defense, devouring a zombie in one bite, the digestion time is thirty seconds, and the time to stay outside is thirty minutes. Hint: Due to the low level, it is now impossible to devour zombies above the Ruby Zombies! ”

Ye Mo read the introduction, and this surprise increased a few points.

Devouring two zombies in one minute, and being able to kill sixty zombies in thirty minutes, the ability of the big mouth flower is really good, and the attack power is stronger than the twelve shells of the pea shooter.

But Ye Mo also found a problem, the pea shooter does not need to be defended, it is a shooter, and it can keep the enemy out, and after the large-mouthed flower is devoured, it cannot continue to attack for thirty seconds, and defense is a problem. According to the data, it can only block ten bites, and its lack of defense is its Achilles' heel.

After learning about the ability of the large-mouthed flower, Ye Mo couldn't wait to put his attention on the corn pitcher. When he played the game, he liked this plant very much, although the attack power in the early stage was not particularly good, but after upgrading, it can be turned into a corn cannon, and the attack effect is increased dozens of times.

"Corn pitcher, long-range attack plant, attack range ninety meters. In every three projectiles, there are two corn kernel attacks, and after hitting the zombie, the effect is half that of the pea shooter; There is also a corn block attack, which is similar to that of the Pea Shooter and can inflict a three-second pause on the zombie. The number of shells, twelve! ”

After reading this, after the system was upgraded to level three, Ye Mo found that there was a close connection between various plants and grades.

Pea shooter and corn pitcher, the number of shells is twelve, which is four times the level.

Potato Thunder and Cherry Bomb, the maximum attack is to destroy twelve ordinary zombies, which is four times the level.

Nuts, 60 bite resistance, is also a multiple of the level.

The attack of the large-mouthed flower, theoretically killing sixty zombies, is also a level multiple.

"This is the system, all kinds of data are regular." Ye Mo thought to himself, "The sunlight value consumption and growth time of plant seeds are also closely related to the grade, which is a hundred times and ten times that of the grade!" ”

In addition to the new plant seeds, Ye Mo also discovered the location of the botanical garden, which became thirty, and there were ten more, so he exchanged eight corn pitcher seeds and two largemouth flower seeds, and cultivated them first.

Ten seeds, three thousand sunshine values were consumed, which was one thousand more than the second-level ones.

The previous twenty plants, Ye Mo did not exchange them again this time, anyway, the effect was good, and it was a pity to give them up directly.

"Okay, there's only one last point left, upgrade cards, are there any of them this time?" Ye Mo was very excited, he had been waiting for the appearance of the upgrade card, and he was most concerned about it every time he upgraded.

His heart fluttered and beating, Ye Mo flipped the system interface, and arrived at the upgrade card.

"Don't be bright, you'll have to be ...... At least one of them would be fine! He whispered.

Interface switching.

Ye Mo saw that two icons lit up here, and suddenly a sense of happiness that his dream came true filled his heart, and he grinned and looked at the two upgrade cards.

The card in first place reads: Garden Expansion Card!

This card can be exchanged for an astonishing price, requiring 50,000 sunshines, but after exchanging, the garden will have ten more slots to expand the slots for plant cultivation.

"You don't have to think about it, of course it's exchanged!" Ye Mo didn't have to think about it at all, and immediately exchanged it. He'd always hated that the garden wasn't enough, and that was the kind of card he desperately needed. However, seeing that the sunshine value was suddenly reduced by 50,000, my heart still hurt.

After the exchange, there were ten more slots in the garden, and Ye Mo exchanged for ten more pea shooter seeds and added them to the cultivation. In doing so, he consumed another three thousand sunshine points.

"It's okay, it's okay, as the saying goes, money is for spending, sunshine is for exchange, and there's half left, isn't it?" Ye Mo thought, "Well, what's the other upgrade card?" Will it be a double-cannon upgrade card? ”

He shifted his gaze expectantly to the next one.
