Doomsday: Unlimited upgrades to the shelter

Chapter 64 Making Defense Robots

Xie Yannan jumped down from the passage, the man who was at the crack of the door just now was already waiting here, but he had a serious face and did not regard Xie Yannan as a guest at all.

Xie Yannan briefly looked around the room.The lights are dim and dim, not as spacious and bright as the shelter under the well, and the whole space looks a bit gloomy.

There is no independent villa, and there are no other people, only the man in front of him, and the steel is piled up one by one.

There are probably more than ten or twenty stacks, each stack is as high as two stories high.Many of them are non-ferrous metals.

"Hello, what kind of steel do you need?" The man spoke slowly, quite well.

This question is relatively simple for Xie Yannan. Although he is a layman, he is a man, and he usually likes to tinker with these things, so he knows more or less about these parts.

A robot is mainly divided into the control part, that is, the brain part, which is composed of software and hardware.Xie Yannan doesn't understand the software part at all, but he plans to use tungsten steel as the material of the hardware, which is not only strong in hardness, but also relatively weak in resistance.

The sensing part is the photosensitive part, which is the robot's perception of external sound, light, and temperature changes. The most important part of the sensing part is the sensor expansion board, which directly determines the range and accuracy of the machine's tolerance.This piece must be polished carefully, because it affects the sensitivity of subsequent robots to monsters.

The second is the execution part. The execution part is mainly to provide power for the robot. Xie Yannan plans to use a geared motor of about 6 volts, which is enough for a basic robot.

Finally, there is the main part of the robot.Undoubtedly, when Xie Yannan chose the material for the brain, he had already decided to use tungsten steel for the whole body of the robot.

Calculated in this way, a robot needs at least 200 kilograms of tungsten steel, but if you are prepared, you can prepare a little more to make weapons for the robot.

"Boss, I bought 260 kilograms of tungsten steel plates, but I don't know how you calculate the cost. I think the boss who sells paper should have told you that I have that kind of pill in my hand.

"Eleven pills can only be exchanged for 250 kilograms of tungsten steel, but my boss said that if you give you a proper discount, then the deal will be considered this time." The man said truthfully.

Even?Dare to say that a few iron plates are so expensive or they are being taken advantage of.But now it seems that this is a monopoly industry, there is no way.Xie Yannan could only conduct the transaction in silence.

[The system has turned on the storage function]

【Tungsten steel 250 kg】

[Sell or store]

【storage】

Xie Yannan didn't want to talk too much nonsense with this expressionless man at all, so he handed him the pill, and then went back the same way.

As he got on the motorcycle, he complained a little.Meow, you guys who sell things are the masters, where is the customer God? !
Today's journey was fairly smooth, as it was when we came here. I didn't meet a single person or a single monster, which made Xie Yannan a little uncomfortable. After all, after the upgrade, he hadn't formally tested how capable he really is.

After opening the door, Xiaoxiao didn't sit there obediently waiting for him as before, and Xie Yannan couldn't help being a little flustered because she couldn't see this little girl in her entire field of vision.

He frowned, and pulled out all the tungsten steel stored in the system.

"Uncle Wei, Xiaocheng, come out." Xie Yannan yelled at the cave where the two of them lived. An electrical engineer and a weapons expert were of great help in making robots.

Uncle Wei came over and walked around the tungsten steel several times, full of praise, "This material is good, and it is also excellent for making weapons. What is Xiaoxie going to use it for?"

Xie Yannan knew that Uncle Wei had just lost his daughter Wei Xiaofei, so he must be very sad, but this matter must be dealt with immediately, otherwise more people may be hurt.

"I plan to use it to make robots, because this is an unfamiliar field to me, so I will rely on the two of you to help design it." Xie Yannan said respectfully.

"Defense robots, or attack robots?" Qin Xiaocheng seemed surprised that Xie Yannan had such an idea.

"Defense against robots, we can't let what happened last night happen again." Xie Yannan frowned, thinking of Wei Xiaofei again, he walked up to Uncle Wei, "Uncle, I'm sorry, when the shelter is remodeled, no matter where Feifei is, I will We must find her and protect her well."

If she was still there at that time, at least she was a healthy human being. If she was no longer there, she didn't have to let herself do it.How can you kill the girl you like with your own hands? !

Uncle Wei shook his head and said nothing, but his eyes were always red.

He squatted on the ground and began to sketch.After all, his identity is there, and he must have seen a lot more internal things than Xie Yannan, and the early warning alone is no longer at the same level.

"Smell warning." Uncle Wei thought for a while, "The sensor uses the blue blood sample of the zombie, and the type is the smell. We have done similar research before and found that the blood of the zombie has a special smell. caused by a mutated virus."

"All creatures infected with that virus will emit that smell once they mutate, and I think the mutant eagle is the same"

Xie Yannan has also thought about this. He even thought of using the unique low roar of zombies.But there is a problem with the roar. Some mutated species cannot make sounds, such as mutated bees.But using mutated blood completely circumvents this loophole. As long as there is mutation, there will definitely be this smell.

"This is desirable. We have solved the biggest problem." Xie Yannan nodded.

[The system has automatically turned on the only mode]

[Tungsten steel 250 kg: processing robot]

[Processing Mode: Defense Robot]

[Defense Ability: Odor Defense]

[Defense level: 5+]

[Defense range: 50 meters in the air, 200 meters on land, 30 meters in water]

【Processing fee: 6000 points】

【Whether to process】

【Yes】

【Processing】

【System points have been updated, now 627 points】

After waiting for a long time this time, Xie Yannan was wondering if there was something wrong with the operation and whether the all-tungsten steel robot system could be made according to the drawings they uploaded.

He looked back, and a robot nearly three meters high had appeared in front of them.

Fuck!This is awesome.

Xie Yannan's mouth almost formed an O shape. He raised his head and glanced at the robot.

The whole body of the robot was a mixture of khaki and gray, with a strong metallic texture, and he couldn't help but reach out with his right hand to touch it.

The robot turned its head reflexively, "Hello."
