Dave, who was sitting there drinking water, was startled by Ryan's sudden shout, and the water in his mouth was choked into his trachea, making a violent coughing sound. Ryan hurriedly stepped forward and slapped him on the back. It took a while for Dave to recover his strength.

He raised his head and looked at Ryan: "How can you solve a problem that a great scientist like me can't solve." ”

Looking at the look of disbelief on Ryan's face, Mad Dave continued: "My enemy is called Dr. Zombie King, he is a zombie with a very high IQ, he has developed a lot of strange zombies, and he is also good at electronics and mechanics, and can make robots bigger than a house. As a result of the failure of an evil experiment, Dr. Zombie synthesized the wisdom of many scientists. ”

"The most important thing. Dave said in a low voice. "He was able to grab the knowledge of people who had become zombies, for example, I started to think he was a simple zombie expert. So he made several robots as helpers, but each time the robots became his minions. ”

Dave shook his head as he spoke, as if remembering something that made her feel unpleasant: "Although I am inferior to him in terms of software, I have also discovered something, and the program he uses has many characteristics of other famous experts, and those experts have all been killed in zombie attacks. So I'm guessing that it's likely that zombies can eat people's brains and gain knowledge for Dr. Zombie. ”

Speaking of this, Dave's eyebrows began to flutter: "When I was about to despair, by chance I began to study these plants that no one had studied before, and it turned out that Dr. Zombie King lacked effective means for these plants, which shows that even if he can devour and digest knowledge by evil means, he cannot learn new knowledge through normal means. So that's why he's trying so hard to control his men to attack me, because only the great Dave knows what these zombie-attacking plants are all about, and only by eating my brains can Dr. Zombie know how to deal with them. ”

After saying these words, Mad Dave glared at Ryan with his eyes of various sizes, as if to say that such a powerful enemy, how can you have the strength to fight against him, you must know that his attainments in this area are equivalent to the attainments of experts in this world.

Ryan looked at Dave, who had disbelief written on his face, and said, "If you believe me, let me go to your underground lab, and I'll show you the solution to the problem." ”

Seeing the determination in Ryan's eyes, Dave shook his head and led him back to the basement (this time Ryan didn't sit on the couch).

Coming to the computer console in the basement, Ryan chooses to extract a copy of the knowledge that has been traded in the world of Frostpunk.

As a golden light floated by, a USB flash drive appeared in Ryan's hand.

After inserting the USB flash drive into the computer, with the help of artificial intelligence, a three-dimensional projection of the difference machine, energy tower, and robot of the Frostpunk World was quickly projected in three dimensions, and various data were marked around it.

Dave pushed Ryan away, looked at these things in front of him and let out an exclamation of amazement: "This is a completely different civilization thing, completely relying on mechanical programming, these robots can realize the functions of logging, mining, taking care of greenhouses, and even taking care of patients." ”

"What's more, the robot is terrifyingly reliable, relying on materials and craftsmanship at most from the early 20th century. It can work in an environment of -150°C. ”

"The most incredible thing is that it's driving this big guy. It's the old steam power. ”

After dancing wildly, Dave turned his head to look at Ryan: "I finally know where your confidence is, this robot does not rely on any electronic components at all, and Dr. Zombie King can't hack into an operating system core composed of gears and perforated steel plates, even if he has strong electronic intrusion capabilities." ”

"With the steam tower power supply and differential machine programming, I think I'll be able to start producing these robots soon, so that my plant army can grow rapidly and I should see the day when zombies are completely wiped out in my lifetime. ”

Speaking of this, Dave crouched down and made eye level with Ryan, "This technology is very important to me, you and I are both businessmen, so I won't make so many detours, you can make a price, I am determined to get this thing." ”

Ryan thought for a moment, "I'm just a kid, and I don't know exactly what this item can get out of you. ”

"Well, since you're willing to trust Dave, then Dave will prepare you to trade goods. You're sure to feel like it's a perfect deal. ”

Although there is now a way to build new robots, the two of them still have to go out and build the fortifications to prevent zombies by themselves. Even with the help of magic, it took the two of them hours to get it all done until the sun went down.

"Isn't there supposed to be someone else in this village? After finishing his work, Ryan thought of something in the game and asked Dave curiously.

"It turned out that there were other people in the town I lived in, but when I found out that the zombies were targeting me, I moved to this abandoned town, and three years have passed. ”

Back at Dave's house, Ryan goes to the bathroom to clean up while Dave prepares to trade items.

Packed up, Dave was already sitting on the couch waiting for Ryan.

"I can transfer you ten plants, three of which can choose advanced plants. With that, he watched as Ryan looked at him with emotionless eyes. He smiled awkwardly and then said: "Of course, in addition to these, a small greenhouse farm recovered this time will also be given to you as your plant cultivation base, and when the robot is built, it will be equipped for you." ”

Hearing this, a smile appeared on the corner of Ryan's mouth, there is a farm greenhouse where you can get a steady stream of plants. Seeing Ryan smile, Dave also breathed a sigh of relief and continued: "In addition, there is also a farm house and the house you own now, and after the robot builds it, I will clean it up for you." ”

With that, Dave pulled out a small pocket from behind him and handed it to Ryan. Ryan reached out and took the pocket, nearly smashing the bag on his foot because he had miscalculated the weight of the pocket. He opened his pocket. It was found that there were some rough chestnut-sized gold ingots, which could weigh several kilograms in total, and they could be exchanged for about 1,000 Galleons when they were taken back.

In addition to gold, there is also a notebook.

"I think you're a whole human society over there and might need this gold. I won't need it anyway, so I'll give you all the things I've collected. Dave said, rubbing his hands. "This notebook contains a little bit of my experience in cultivating plants, you can check it out. ”

After selecting the plants, Ryan said goodbye to Dave with satisfaction, and then walked out of Dave's house. The choice is back in the Wanjie grocery store.
