After the upgrade of the fourth-level city, Ye Chuchen made a decision that neither Qiu Jieming nor Yan Xiong expected.

That is the Open Dawn City.

The outer city of Dawn City is open to the outside world, and various housing and residential areas are widely built.

At the same time, in addition to the core technology, Dawning City also opens up other technologies to the outside world.

For example, plant-mounted mechs.

In fact, Ye Chuchen's elder brother Ye Yunchuan has never stopped researching plant-mounted mechas.

And Ye Chuchen, in order to help Ye Yunchuan, also purchased many documents of plant-mounted mecha in various technological worlds in Wanjie City.

Now in the fourth-level Dawning City, the science and technology laboratory is even more complete than the science and technology laboratory of any country before the end of the world, and the equipment is more advanced.

Moreover, Ye Chuchen also wanted Ye Yunchuan to go to his own branch city to manage the branch city arsenal, where Ye Yunchuan could give full play to his love for science and technology.

Even, Ye Chuchen wanted to take Ye Yunchuan to the main city of Ten Thousand Realms City, where there were more teachers.

For example, the old dry pot, although Ye Yunchuan is good at science and technology, but the sword casting technique of the old dry pot is not just a thousand hammers of red-hot iron under the iron hammer.

However, just a week after Dawn City came to Jincheng.

Ye Yunchuan appeared in the sun for the first time, running back and forth in the city, shouting that he had succeeded and something like that.

even made an oolong because of this.

In the first battle of Jincheng, there were very few people in the city guard army who knew Ye Yunchuan, and now that the city guard army has expanded, there are even fewer people who know Ye Yunchuan.

Didn't even hear it.

When Ye Chuchen wanted to go to his brother, he found that his brother was not in the laboratory.

After asking around, even when Ye Chuchen was angry and lifted the conference room table, he knew that his brother had been arrested as a madman.

Fortunately, Ye Chu did not have the intention of killing.

However, Ye Yunchuan's first reaction when he saw Ye Chuchen did not complain that the people of the city guards arrested him, and even thanked those who arrested him, because during the time he was arrested, Ye Yunchuan had new inspiration.

Soon, a generation of plant-mounted mecha appeared in front of Ye Chuchen.

"Achen, this is the original plant-mounted mecha."

Ye Yunchuan put the plant-mounted mecha in front of Ye Chuchen.

"A generation of plant-mounted mecha, what I care about is his aggressiveness and flexibility, so I don't have much defensive armor, mainly for ordinary people who don't have abilities."

Then, Ye Yunchuan raised the arm of the botanical mecha.

"Here I made a barrel that can fire bullets to attack, the bullet capacity is fifty rounds, and I put the trigger in the palm of my hand."

"Here!" Ye Yunchuan pointed to the legs of the plant-mounted mecha again: "Here, according to ergonomics, I have designed a complete set of devices that are in line with the program to enhance the speed of ordinary people. ”

"This device can make a lame person run a good result of 100 meters and 10 seconds! If it were a normal person, it would be faster! ”

"Here, here is the core part of the entire implanted mecha, the energy storage chamber, I estimated, this energy storage bin can ensure that the implanted mecha can be used for sixteen hours under the highest energy consumption, and the energy source is through a device in the laboratory, the crystal nucleus is converted into a liquid, and the energy storage chamber is this liquid."

After introducing the plant-mounted mecha, Ye Yunchuan couldn't wait to go up to himself to give it a try, but was stopped by Ye Chuchen.

"Brother, I'm not sure if the program will be out of order, if you try it so rashly, if the program is out of order during the trial, the consequences will be unimaginable."

And Ye Yunchuan pulled Ye Chuchen's hand away.

"Achen, I am the designer and manufacturer of this plant-mounted mecha, and only my personal experience is the most representative."

Regardless of Ye Chuchen's opposition, Ye Yunchuan directly put on the plant-armored mecha.

Soon, after matching the receiving device in the helmet through brain waves, Ye Yunchuan quickly controlled this set of plant-mounted mecha.

The original plant-mounted mecha was two meters high, and after Ye Yunchuan put it on, there were indeed many frontal parts that were exposed to the air.

But as Ye Yunchuan said, his plant-mounted mecha has very good flexibility, and because it is controlled by brainwaves, it is extremely easy to run-in.

Ye Yunchuan raised his hand, and Ye Chuchen quickly condensed a shield with black qi and put it in front of him.

"Achen, get out of the way! What if you can't stop this shield? ”

Ye Chuchen smiled and said, "Boss, I believe in my shield, more than you believe in your mecha." ”

Ye Yunchuan was no longer entangled, raised his hand and began to attack towards Ye Chuchen's shield.

There are two buttons in the palm of your hand to control the firing of bullets, one is single-shot and the other is fully automatic.

Ye Yunchuan didn't keep it, and directly used a fully automatic launch.

7.62 caliber, fifty rounds, all fired in ten seconds.

"Five bullets per second, as a first-generation plant-mounted mecha, the speed is okay, but the power is too weak."

Seeing that Ye Chuchen's shield was safe and sound, not even a single bullet crater, Ye Yunchuan looked a little disappointed.

"It's not weak in power!" Ye Chuchen put away his shield, "A bullet of the same caliber, its power can already catch up with the army's standard assault rifle, or even stronger, it's normal if it doesn't break my shield, brother, if I don't blow it, the tank can't be broken!" ”

"Although this plant-mounted mecha can greatly reduce the user's physical exertion, it is best to let young and strong people who have been trained for a long time wear it, because the most expensive thing about the plant-mounted mecha is the human spirit, and people who exercise regularly will have more willpower than others."

......

The success of the first plant-mounted mecha made Ye Chuchen quickly push it to the market.

Now the business area is all some rice, vegetables and a series of products, these products are directly supplied by the farm, the third level of farms, can produce seasonal vegetables and fruits, which is already very good.

Moreover, in the last days, it is everyone's dream to be able to eat vegetables and fruits that are fresher than before the end of the world.

And now, the first plant-mounted mecha shop opened, and it quickly attracted onlookers.

Through cost calculation, the cost of a plant-mounted mecha is 25 crystal nuclei, and Ye Chuchen sells sixty-five crystal nuclei for one, is this expensive? Not expensive!

Although there is no mass production, the store staff display the plant mecha in front of the store every day, so there are many people who want to buy it.

Ye Chuchen even learned the excellent business thinking of a video platform before the end of the world.

Now that the supply is tight, an advance purchase campaign has been launched, but anyone who buys the first generation of plant mechas, as long as they spend five more crystal nuclei for each one, they can give priority to other buyers to get the first generation of plant mechas!

Is this a robbery? No!

You see! The eighty-eighth division bought ten in one go.

Each of them participated in the advance purchase activity, a total of 700 crystal nuclei were recorded, excluding the cost price of 250 crystal nuclei, Ye Chuchen made a net profit of 450 crystal nuclei!

Do you earn more? Not much!
