The micro reactor has been finished. After some consideration, Fangyuan asked Qingqiong to develop a micro aircraft.

The diameter of the super battery aircraft is ten meters, which he thinks is a bit big.

If an aircraft with a diameter of about two to three meters can be developed, it will be more convenient to take off and land.

With the technology mastered by Cangqiong, it is not difficult to develop an aircraft with a diameter of one meter.

Each kilogram of super battery can store up to 5,000 kilowatt hours of electricity.

A fist-sized micro-reactor is much more powerful than a super battery.

"Hybrid power is more reliable. If the circuit fails, the reactor can still be used."

Let Qingqiong design the micro-aircraft, and Fangyuan watch the undulating waves and the boundless sea.

"When fishing, whether you can catch fish depends first on whether there are fish."

With this thought in mind, Fangyuan decided to make a diving fish finder.

Whether it is the real world or the current world, there are many kinds of fish finders.

Fangyuan felt that wired fish finders were not convenient enough and had limited detection range. He wanted to build a fish finder similar to that of a submarine.

Wireless ultrasonic sonar fish finders and the like can only detect whether there are fish, but it is difficult to identify what fish they are.

If you don’t have enough fishing skills, you need some equipment.

If there is a fish finder similar to a submarine, it can catch countless fish in rivers, oceans, reservoirs and lakes.

Using bait research and development equipment, you can develop corresponding bait.

A variety of baits can also be purchased in the system fishing gear mall.

If he can know what kind of fish is underwater and how big it is, he can choose the corresponding bait and suitable hook.

The liquid metal robot can serve as a fish finder, but the liquid metal robot is too big.

When I return to the real world to fish, my wife is basically there, so it is not suitable to use a liquid metal robot.

Fangyuan, who was too lazy to bother, asked Qingqiong to design a miniature diving fish finder.

"It's ten centimeters long and eight centimeters in diameter. It looks like a miniature submarine. It looks pretty good."

Due to body size limitations, the super battery of the diving fish finder only has a capacity of one thousand kilowatt hours.

Referring to the design drawings provided by Cangqiong, Fangyuan found the corresponding materials.

He used his special powers to process the metal parts, and in less than three days, the diving fish finder was completed.

Connect the smart watch and throw the diving fish finder into the sea.

Fangyuan lets the sky project the images captured by the diving fish finder.

But I saw the colorful seabed, full of all kinds of fish, shrimps and crabs.

"That abalone weighs at least a hundred pounds, a mutated abalone?"

Giving up on the idea of ​​tasting mutated abalone, Fangyuan let Qianqiong control the diving fish finder and move forward at a speed of about five meters per second.

A few minutes later, a big fish swam over and swallowed the diving fish finder in one gulp.

"Fuck, you just swallowed it without even biting it?"

The diving fish finder is very strong and can definitely break the teeth of big fish.

When encountering a big fish that has been swallowed alive, Fangyuan felt like crying.

The newly built diving fish finder was swallowed by a big fish within ten minutes of use.

"It was eaten and I couldn't pull it out. My diving fish finder is equivalent to being scrapped."

After thinking about it, Fangyuan used the remaining materials to recreate a diving fish finder.

"A submersible fish finder with an additional drill bit can drill out even if it is eaten by a big fish."

Fangyuan threw the drill version of the diving fish finder into the sea and looked at the projection again.

The diving fish finder has a total of six cameras, taking into account the front, rear, left, right, and up and down.

The image projected by the smart watch is like a three-dimensional space.

There are many carnivorous fish in the sea, and within ten minutes, the diving fish finder was swallowed by a big fish again.

The drill bit at the front of the fish finder rotated at high speed, and in an instant, it came out of the body of the big fish.

Fangyuan is extremely satisfied with the test results of the drill version of the submersible fish finder.

The super battery has a capacity of one thousand kilowatt-hours and can be used for more than two months under normal circumstances.

"Theoretically, the maximum diving depth of a diving fish finder is 30,000 meters. If it exceeds 30,000 meters, the submersible will break down."

On a whim, Fangyuan decided to make several earth drills based on the diving fish finder.

The construction speed of Hexiahe and Haixiahai in the real world is not fast enough.

If you have several earth drills and drill at the bottom of rivers and seabeds, you can easily drill under rivers and under seas.

"The ocean version of the earth drill has a diameter of ten meters, and the river version of the earth drill has a diameter of five meters."

Let Qingqiong design the earth drill, let the robot prepare the corresponding materials, and Fangyuan spent several days fishing at sea.

With the help of a diving fish finder, he caught mutant fish one after another and racked up a lot of fishing numbers.

Coming to the robot factory, Fangyuan used metal powers to create a marine version of the earth drill.

"The enlarged version of the micro-reactor provides power, and the fuel rods can be replaced once and can work continuously for several years."

"After returning to the real world, we will drill some channels on the seabed of the offshore sea and the bottom of the Qinghe River."

It took Fangyuan half a month to build the first marine version of the earth drill.

The marine earth drill was put into the sea and tested over and over again. All the data met the design requirements.

The river version of the earth drill is equivalent to a smaller version of the ocean version of the earth drill. It is easy to manufacture and takes less time.

Fangyuan rebuilt three ocean earth drills and three river earth drills, used elemental air purifiers to purify the air within a radius of a hundred meters, and cast the light of purification, and then retracted the six earth drills into the system space.

.

He looked at the elemental air purifier bathed in purifying light, and then put it back into the system space.

“The drill version of the submersible fish finder is not safe enough, please redesign it.”

As soon as the idea changed, Fangyuan asked Cangqiong to redesign the drill version of the submersible fish finder.

A high-speed rotating drill bit can drill through steel, let alone flesh and blood.

Don’t be afraid of ten thousand, just be afraid of what happens.

Fangyuan was worried that one of his careless actions would result in someone missing an arm or a leg, or even die without a complete body.

"When the fish is not eating it, the drill bit of the submersible fish finder shrinks. When it is eaten by a fish, the drill bit of the submersible fish finder comes out. This is much safer."

The drill bit of the new version of the diving fish finder is composed of four high-strength blades. When not in use, the blades are in a retracted state, and they will pop out only when needed.

With the idea of ​​being prepared, Fangyuan made ten diving fish finders in one go.

He has metal powers and can process metal with ease.

The technology in this world is decades ahead of the real world.

He would feel sorry for himself if he didn't take advantage of the current availability of equipment, materials, and technology to do more things.

If you don't take what God gives you, you will suffer from it.

"I haven't talked to anyone for a long time. I'm going to a gathering place for a few days."

As soon as his thoughts changed, Fangyuan left on his motorcycle.

Arriving at a gathering place and looking around, he felt a little refreshed.

It has been almost 20 years since the zombie virus became extinct, and the total number of survivors in the world is about 80 million.

Among them, the number of survivors in Huangzhou has increased to more than 60 million, and the total number of survivors in the other continents is just over 10 million.

Genetically modified food cannot be used to save seeds. The survivors of Baizhou, Xingzhou, Mineral Continent, and Black Continent often go outside to look for food. When they encounter mutant beasts, there is no guarantee that they will not suffer casualties or even be wiped out.

There are no more zombies or zombie animals, but there are a lot of mutant beasts.

After staying at the gathering place for more than a week, Fangyuan left quietly.

The number of technical personnel has been exhausted, and the survivors are making slow progress in rebuilding their homes.

Not to mention whether the plane can still be used, even if it can be used, there are not many people who can fly it.

As for the satellites in the sky, how can we use satellites without the corresponding equipment and talents?

Fangyuan doesn't really care what happens to this world, as long as he can go back alive.

I found a mountain pool, prepared some freshwater fish bait, and threw some away.

In a state of light lifting but heavy lifting, fish less than two ounces have a good handle.
