On a planet that is not many planes away from the earth, the sky is clear and the sun is shining.

If you look at the planet from space, you will see that the whole planet seems to be green.

Slowly approaching the surface of the earth, you can occasionally see the remains of human buildings, but both buildings and towers are full of strange plants.

Occasionally, pedestrians can be seen on the road, but they walk like walking corpses.

It's a wasteland world!

Zombies can be seen everywhere, and there is no trace of the existence of living people.

There is only one living person in this world, who lives in a city surrounded by walls like Attack on Titan, but the walls of this city are all brown giant trees.

Countless vines grow under the trunk of the tree, and as long as a zombie comes, the vine will mercilessly strangle the zombie.

There is also a giant tree in the center of the city, on which there is a palace, where the only living person in this world lives.

His name is Dave.

At this point, Dave roared excitedly.

"Finally, we have finally found another system host! Oh my God, it cost me a billion dollars, my whole net worth! The system is really pitiful, but fortunately, it left me a glimmer of life! Dave shouted excitedly.

Living alone, Dave has become accustomed to talking to himself.

He immediately began to communicate with the host of the plant system in the other planes, which was his only hope of saving himself.

"Hello!" Dave shuddered and sent out a greeting.

"Hello, big guy!" Yang Zhou also couldn't wait to reply.

This is a level 6 boss, and he is also ready to take the initiative to search for system hosts in other planes in the future, but he didn't expect someone to take the initiative to find him, he was so excited.

Dave was so excited that he couldn't control his emotions and didn't send a message for a long time.

Yang Zhou couldn't help it anymore, and took the initiative to ask: "Big guy, what do you call it, are you already level 6?" Is there a cancer treatment seed? ”

"Yes! It's too much, as many as you want, you wait for me to put the seeds on the shelves right away. Dave finally came to his senses and replied.

Yang Zhou has already opened the other party's mall page, a total of 6 empty stalls, there were no goods in them before, just waiting for a while, refreshing again, and seeing the cancer treatment seeds he had been thinking about for a long time!

"Wow, it worked, I actually bought a level 5 seed at level 4, that's great." Yang Zhou spent a full 10 million experience points, but at this time, he was not distressed at all.

Dave didn't increase the price, but hung up the seeds at the original price.

His illness has been saved!

Looking at a seed lying in the system warehouse, Yang Zhou didn't care about chatting, and hurriedly planted it in the system land, adjusted the local environment of the space according to the living habits introduced by the seed, and poured the space spring water.

Now we just need to be patient, and it won't be long before the fruits are harvested.

At present, Yang Zhou does not know how to use it.

The seeds purchased by other people are not very detailed, and you need to ask the other party patiently to know.

"Hello Dave, my name is Yang Zhou, do you know how to use the cancer treatment seeds after they are planted?" Yang Zhou asked.

Dave also came back to his senses and began to ask Yang Zhou for his personal information, and learned that Yang Zhou had just been promoted to level 4 and had terminal cancer, so he simply told Yang Zhou how to use cancer treatment seeds.

"It seems that the people who get the system are actually unlucky, I was once terminally ill, cancer seeds are actually a concentrated genetic plant, which grows in the form of vines, and the ripe fruits are more special, and more than 300 kinds of special plant fruits will be born, and these fruits are not medicines, but contain different kinds of plant seeds."

"Plant seeds need to be planted to extract substances that are harmful to cancer cells." Dave explained in detail.

Yang Zhou chuckled in his heart, do you have to plant it again, what if some plants grow for a long time and he can't catch up!

After asking, Yang Zhou was relieved.

Dave answered all the questions, and quickly talked about the growth cycle of other seeds, the longest of which was no more than 1 year, with his four-level system, 32 times the ability to accelerate.

1 year old plant, it only takes 11 days to harvest.

It's completely in time, he will be able to obtain a complete healing plant in about ten days, and when the time comes, the extraction of plant elements, according to Dave, whether it is boiling soup or extracting plant essence medicine, can save his life.

As the chat deepened, Yang Zhou also slowly learned about Dave's situation.

His name is the same as the male protagonist in Plants vs. Zombies, and what is even more exaggerated is that Dave's planet is also full of zombies, and he is transforming countless plants to resist zombie invasion, and he lives in a plant city.

"My friend, I have to give you a piece of advice, when using the system, you must pay attention to some details, I am the only one in my world, in fact, it is all caused by me!" Dave messaged.

The two were separated by planes, without any conflict of interest, and Yang Zhou didn't have to guard against Dave, so he humbly asked for advice.

Dave felt bitter in his heart and slowly told his story.

It turns out that Dave once lived in a modern civilized society with advanced science and technology, and in terms of scientific and technological development, it should surpass the earth.

And the planet he lives on is a parallel plane to the earth.

The equivalent of the words used by the two is actually the same.

The English used by Dave was automatically translated into Chinese by the system, and Dave also had computers and mobile phones.

Yang Zhou estimated that the level of science and technology before the destruction of the other world was likely to be about 20 years ahead of the earth, and Dave himself played an important role in this 20 years ahead.

For example, the progress of various aviation materials and the development of battery technology are all related to Dave's special plants.

"What's the reason that the whole world has become zombies?" Yang Zhou asked suspiciously.

"The bacteria that come with the system! You must not let them spread to your planet without restrictions, this bacteria contain genetically modified proteins, everything is my fault, I trusted a person who should not be trusted, it was originally to facilitate others to get special bacteria and improve the development of science and technology faster, but that person was greedy. ”

"He extracted proteins that could modify genes, engineered special bacteria, and finally allowed the virus to spread to the whole world, the whole world was filled with this virus, all animals were infected, they became irrational monsters, low intelligence and bloodthirsty!"

"And they will also reproduce offspring, but their intelligence has degenerated to the realm of beasts, and it may take millions of years to evolve before intelligence can be born again!"

Yang Zhou looked at it for a long time and couldn't help asking, "Didn't you add the genetic lock that comes with the system?" ”

"......., yes, so it's all my fault, I shouldn't trust others, if there is a genetic lock, nothing will happen! No one can crack the genetic lock produced by the system, even if I am already level 6, it is all my fault!! Dave replied bitterly.

"I understand, in the future, I will protect the bacteria produced by the system, and absolutely no original version will be leaked." Yang Zhou replied with a sigh.

He and Dave have been added as friends, and they can communicate at any time in the future, Yang Zhou felt that Mrs. Dai was not bad, and wanted to help him, so he asked, "Is there anything I can help you?" ”

"Yes! Yes! It's so much.,Only you can help me.,The system's search for friends function,Very pit,Very, very pit,It's the same as your card drawing krypton.,Spending a lot of money doesn't necessarily have results.,I'm penniless.,I can't use these functions anymore.,Because of my world.,I'm alone.,There's no way to upgrade the system.,Can't draw cards and search for other friends.。 ”

"You are my only friend, I can only count on you, if I want to continue my civilization, I have to have women, I have to have the opposite sex! But, my planet, there is no normal opposite sex anymore, and those mutants or the zombies you say, there is reproductive isolation between us! ”

"I can't get a frozen sperm bank, it takes time to plant plants with combat power, I only have one person, as long as I leave the city I transformed, countless monsters can kill me, and I'm already trapped in a lonely city."

Yang Zhou was a little confused, and replied: "So, you need a woman?" But I can't send it to you! ”

"There is a way, there is a way, does the World Tree know? The fruit of the World Tree can give birth to elves, I have been able to see the information of the level 7 system store, the world tree can be purchased at level 7, you can quickly upgrade to level 7, and then the mall will hang seeds for me to buy, and I will be able to breed a whole new race myself! ”

"With the elves, my planet will have a trade, and my system can be upgraded!"

"Moreover, you can also draw a lottery, and if you're lucky, you might be able to draw a World Tree seed!"

"I can do my best to help you upgrade, so that you can shorten the upgrade speed, you can also help me, we are the best partner!"

It can be seen that Dave is very excited and has sent a lot of messages in a row.

Yang Zhou was actually a little puzzled, and said strangely: "Where did you get the experience points, to buy the World Tree, according to the rules of fair trade in the system, you also need to come up with at least 10 billion experience points." ”

"Hehe, there are many ways to get experience points, hunting zombies is one of them, and you can also transform plants to earn experience points, and before the destruction of my world, I was already the most powerful scientist in the world, with hundreds of millions of fans and more than 10 billion experience points, so, I am actually very rich, but very poor." Dave replied reluctantly.

Yang Zhou understood that Dave had killed himself.

His hundreds of millions of fans, and in the end, he became a "beast".

It's sad to think that Dave is the only one left in the world, no wonder he wants to get the World Tree and reproduce a civilization again.

"Okay, I promised, when I reach level 7, I will buy the World Tree seeds and sell them to you at the original price." Yang Zhou finally replied.

The two talked a lot, Dave is a level 6 boss, and he also has the scientific and technological power of a parallel world.

For Yang Zhou, there are too many benefits.

Being able to have such a person who can ask for help at any time can also speed up his own development.

He no longer has to understand the genes of yew trees and don't know how to modify them, Dave has a lot of experience in plant modification.

Of course, Yang Zhou can't just buy the seeds of Dave's plane, the system mall stall, but there are restrictions, upgrade to a stall.

Yang Zhou had a stall before hanging hybrid rice, worth 1 million experience points.

To open a stall, you need krypton.

Dave's experience value is rich, but the krypton value is zero, and he can't open more stalls.

But there are still a few stalls where you can hang 5 plant seeds.

These 5 kinds of plants should be carefully considered and not wasted.

ps: I woke up in the middle of the night to go to the toilet, and suddenly thought that today was Monday, but I saw that there were only 11 votes alone, and the reward was also cleared, so I was so scared that I hurriedly wrote a chapter, this is a 3.3k big chapter, please vote, invest, and reward! In the new week, you need all kinds of data support, so you must advance! Next week's promotion is to be strong, kneel and beg all readers! The protagonist will also speed up his development, and the protagonist will not be suppressed in the future.
