Late at night.

In the vast sea of sand dunes on the plane of machine 2186, a long dragon wrapped in smoke and dust is running wildly from east to west, crossing one sand dune after another, and finally, seeing the pillar of light in front of him, he rushed into a valley at high speed, and two dusty expedition vehicles entered the base in a hurry.

Finally back.

Lu Wei took off his protective suit, opened the car door, stepped down from the expedition vehicle, stepped on the solid metal floor, dusted off his body, and heard Kai's familiar voice.

"Welcome back, my friend."

"Five expedition vehicles, two were swallowed up by quicksand, and one was blown away by the storm, next time I go out to find a base to put it in, Kai, you may not welcome me back." Lu Wei opened his mouth and complained.

"Uh...... The losses are indeed more than I thought, my friend, and I'm trying to figure out how to fix this. ”

"How to fix it?" Coming to the main control hall, Lu Wei took a cup and made a cup of hot coffee on the water dispenser, held the coffee, sat on the office chair and asked.

"I designed this." Kai pulled up a blueprint, "I was inspired by the kind of plane you bought last time, so I designed a similar drone with four wings, but it's bigger, it can fly farther, and it can find directions." ”

The drones Kai said were the three Dajiang Mirage 3 quadcopter drones that Lu Wei bought before, and this kind of drone left a deep impression on Kai, and even analyzed and studied it.

It's just that in the process of use, all three drones were damaged, which added a certain degree of difficulty to Lu Wei's later pathfinding work.

Seeing this design drawing, Lu Wei's spirit rose, this thing is so cool, the volume is hundreds of times larger than Dajiang Phantom 3, not to mention. The equipment that this drone can carry in the picture is also varied, including cameras, communication devices, radar detectors, terrain sounders, and four landing brackets, which also support this drone to land on any terrain.

And that's not all. The power system used in this drone is an energy core, and filling one can make this drone have almost unlimited cruising capabilities.

"This drone is very good, Kai, you can develop it right away and put it into use." Lu Wei took a sip of coffee and said.

"I'm afraid it's not going to work, my friend, I can't make this kind of drone for the time being."

Lu Wei made a movement in his hand and asked, "What's the matter?" The base can even build such a huge base car, and it can't build a small drone? ”

"No, friend, it's not as simple as you think, if you ask me to design and build a drone, there is no problem, but the environment outside the base is very harsh, low temperature. Strong winds, windy sand...... UAVs do not have thick armor. There will definitely be a lot of problems during use, and I need you to help me provide some materials. "Kaidao,

"Material, what material?"

"Some lightweight insulation materials also need to have a certain degree of insulation and high toughness, just like the materials used in the last few drones you brought along. I'll ask you to provide some. ”

"Isn't that plastic, Kai, I have a lot of this kind of material in that place, how much to supply, and it shouldn't be difficult to produce. Why, the base cannot produce this material? ”

Lu Wei asked in surprise, as the pinnacle of science and technology, he has always believed that the tower base is omnipotent, and can use existing elements to produce various items, how can it not be possible to build a drone?

"Well, friend, what you think is too simple, the main task of the tower defense base is to collect energy, not specifically to study various equipment, in addition, in terms of materials, the base can purify the substance, but it is difficult to combine the substance, the base can not produce the kind of 'plastic' you said, if you can, the base can develop anything you want." Kay explained.

"Okay, that's no problem, Kai, I can bring you plastic materials to the base from the other side of the earth right away, and provide as much as I want!"

Lu Wei said excitedly, only then did he discover what was the bottleneck restricting the development of science and technology in the base, it turned out to be the synthesis technology of organic materials!

It is no wonder why the purity of the metal materials produced by the base is basically more than six nines, and theoretically reaches 100 percent, but in terms of material synthesis, there is no relevant synthesis equipment...... There is only decomposition, no synthesis, how can the development of science and technology be promoted.

Take this side of the earth as an example, whether it is television, computers, refrigerators, buckets, basins, garbage cans, plastic bags, toothpaste, toothbrushes, cars, airplanes, clothes, shoes, ...... Plastic products have penetrated into 100% of human life, and people are exposed to plastic the most every day, but the tower defense base can not even produce an insulated wire.

Just walking on crutches.

Kai thought for a moment, then shook his head and said, "Wei, if you can provide enough of that 'plastic' material as you said, and I apply this material to various systems of the base, I can reduce the power consumption of the base by 50% and increase the output of energy cores by 15%, but your plane shuttle can only carry a small amount of plastic at a time, which is not enough at all." ”

"What?"

Lu Wei's eyes widened, emitting an extremely bright light, reducing energy consumption by 50%, increasing the output of energy cores by 15%, and an ordinary plastic can also bring this benefit, which ......

"It's true, most of the electricity consumption at the base is used for heat generation and insulation, and if you use plastic, you can save that energy, but you can't provide that much plastic," Kay explained. Kai shook his head in regret.

"I see." Lu Wei muttered in his mouth, but he remembered it deeply in his heart.

"Also, Wei, I have good news for you, the first base vehicle you placed has collected enough resources and is now upgraded to a first-class tower defense base." Kai said, bringing up a scene.

This scene is the interior scene of the new No. 1 base, and there is also an energy center in the shot, as well as a defense platform, and 48 empty towers, similar to the scene Lu Wei saw when he first came to this tower defense base.

Lu Wei sighed in his heart, just like a level 100 player who has cleared the level, seeing himself in the novice stage, a sense of familiarity that makes people feel emotional.

"Wei, the energy collection cover of Base 1 has been deployed, as long as the underground turbine is started, it can start to collect energy, is it started?"

"Uh, start!" Lu Wei quickly reacted slightly in a distraction and gave an order.

As a result, on the endless vast continent of the 2186 plane of the machine, two pillars of light appeared to the sky, reflecting each other, making this gray continent seem to have increased a lot of brightness. (To be continued......)
