But no matter what.

This thing has to be done, and if you don't do it, the firefighting drone won't be able to fly.

Tang Rui picked up the aluminum alloy plate and began to work.

After a few days of practice.

His welding skills have improved significantly.

Although the effect of fish scales cannot be welded, at least it will not be welded through the holes.

The welded parts are also well sealed.

Twelve pipes were welded.

Take out the grinding wheel and start sanding.

After sanding.

Put the catapult on the bottom.

Finally, the aluminum alloy plate welded the twelve pipes together.

Tang Rui made a rectangular launcher, with twelve tubes arranged in three rows, each row of four launch tubes.

After doing this, he built a base for the launcher, and installed a universal wheel and motor.

This motor adjusts the orientation and tilt angle of the transmitter.

By the time he finished the entire launcher, it was already dark outside.

Don't look at it, it's easy to say.

But it's still a bit cumbersome to do.

Tang Rui took out his mobile phone and looked at the time, it was almost 7 o'clock.

No wonder I'm a little hungry, it's past dinner.

After working for a long time, he didn't want to go out to eat.

Ordered a takeout directly.

"Have you finished eating?"

This is the message that Li Shuyao sent to him ten minutes ago.

But he didn't see it.

"No, I just finished busy, I ordered a takeout, and it is estimated that it will be delivered in ten minutes."

After Tang Rui finished ordering takeout, he replied to a message.

didn't wait for Li Shuyao to reply.

He clicked on the circle of friends, ready to see what everyone had posted recently.

As soon as I opened it, I saw a new circle of friends.

"What do you do to make money fast? I'm so short of money! ”

This is a circle of friends posted by the senior in the CLP department.

It's obvious.

It's a lack of money.

Although he earns a lot, it is considered a high salary in the country.

But the problem is, house prices are higher.

Tang Rui said at a low price below: Printing money is fast.

Someone gave him a thumbs up right away.

And then.

The senior immediately replied: Junior brother, don't you know that printing counterfeit money is illegal?

Tang Rui: Senior, you can print real money.

Senior: What you said makes a lot of sense, but the problem is, I don't have a gravure press.

Tang Rui: I can get it, senior, do you want to make a lot of money together?

Senior: Really? Then I'll go get acid-free paper now.

Zhou Tao: Add me one, I'll do color-changing ink.

Senior: Who is going to do the backing board?

Zhou Tao: I have a friend who is CAFA, and I can ask him to draw one.

Tang Rui: Let's live, let's make a lot of money together.

Senior: Wait, there's a knock on the door, I'll go get the delivery.

Seeing the senior disappear, Tang Rui continued to scroll down the circle of friends.

Looks like everyone is joking.

But in reality, he was able to get his hands on a gravure press.

Build your own.

Then upgrade and strengthen it with the system panel.

The printing effect is guaranteed to be better than that of the Federal Reserve.

"Do you want to come out and have a drink, South Street food stalls."

Zhou Tao sent him a message.

"No, there's something to do at night."

Tang Rui replied immediately.

Joke.

Wait a minute, he still has to work out, how can he go out to eat food stalls.

"What's the situation? There's something wrong with you. ”

"Dad is designing drones, so I don't have time to play with you."

"Designing drones? Why don't you talk about designing spaceships?

Dad understands, am I going to be a grandfather? ”

"Roll ......"

"Slut."

After talking to Zhou Tao for a while, the takeaway brother arrived.

A bowl of braised beef rice bowl.

Not much beef.

There are quite a lot of potatoes.

But the taste is not bad, and the portion is okay, enough for him to eat.

Wait until you finish eating.

More than half an hour passed.

Tang Rui changed his clothes, picked up his mobile phone and sent a video to Li Shuyao.

"Why haven't you changed your clothes and don't work out?"

"Fitness? Are you okay? Li Shuyao was surprised.

Last night, Tang Rui was as tired as a dead fish.

It stands to reason that today is not to mention fitness.

He can move slowly, and he is in good health.

As a result, I also deliberately sent her a video to exercise together.

"Why can't it, can a man say no. Hurry up and change your clothes, I'll wait for you. ”

Tang Rui urged Li Shuyao to change clothes.

looked at Tang Rui with a serious face.

Li Shuyao's expression was very subtle, but she still turned around and went back to the house to change her clothes.

A few minutes later.

Li Shuyao, who finished changing clothes, appeared on the screen.

Tang Rui's eyes widened suddenly.

Because today she didn't wear that tight gym suit, but a loose sports vest.

The three-dimensional sense came out instantly.

"Let's do a warm-up exercise first."

After Li Shuyao saw Tang Rui's eyes, her ears were slightly red.

Although she still wears something inside, she still looks fierce when she puts it on this background.

Soon.

The warm-up exercise is done.

The two got on the treadmill and started running.

Li Shuyao has been observing Tang Rui.

She thought that Tang Rui was stiffening, and her body might be in pain.

As a result, after running for a while, she realized that something was wrong.

Tang Rui's expression didn't change much.

It doesn't look like you're running with the pain at all.

Even if you are an actor, you can't do this, after all, the pain in your body is not something you can hide if you can.

"How did you do that?"

"What?"

"Don't your muscles hurt?"

"It hurt a lot last night, but I pressed it with a fascia gun for a long time, and I recovered today."

After listening to it, Li Shuyao did not delve into it.

After all, people's physiques are different, and Tang Rui can't be said to be the kind of physique that recovers quickly.

Exercised for an hour.

The two of them finished their workout and hung up the video.

After Tang Rui lay on the ground for a while, he got up and went to take a bath.

Today is much better than yesterday.

It's still tiring, but it's definitely stronger than yesterday.

The sit-up machine was also upgraded by him, but the first level was useless at all.

After taking a shower.

Tang Rui lay on the bed, took out the fascia gun and began to relax and massage the muscles.

I pressed it for more than an hour.

He didn't stop until his muscles were relaxed.

"I can't sleep."

He swiped his phone on the bed for a while, feeling bored.

Originally, the young lady who was on the cause, he could still see it.

But after exercising with Li Shuyao for the past two days, he looked at these young ladies who were shaking the cause, and he was as happy as water.

After all, there is an audit for Shake.

But WeChat videos are not moderated.

Just now, Li Shuyao's fitness video can't pass the trial on Douyin.

In addition, after exercising, the cells of his whole body are active, and he is not sleepy at all.

What are you doing?

Going to fly a drone?

Tang Rui shook his head and didn't want to go out.

It's all done showering.

When you go out to fly a drone, you must be sweating, and you have to take a shower when you come back, which is troublesome.

Wrong.

It occurred to him suddenly.

Even if he doesn't leave the house, he can play with drones.

It's nothing but a firefighting drone.

This thing doesn't need a runway, as long as there is no obstruction, it can be launched from anywhere.

Tang Rui glanced at the large balcony outside the house.

Balcony of more than 10 square meters.

It can be used as a launch pad at all.

Come to think of it.

He got up inside and moved the drone launcher to the second-floor balcony.

Then the firefighting drones were inserted into the launch canister one by one.

Finish doing these.

He took out his laptop and opened the drone control program.

After adjusting the orientation and tilt angle of the launcher, he pressed the launch button.

Launch!

Woohoo......

Twelve launch tubes, starting from the left, the first vertical row is fired sequentially from top to bottom.

Then start the third vertical row on the left and continue firing from top to bottom.

This is followed by the second and fourth vertical rows.

Less than three seconds.

Twelve firefighting drones, all launched into the air.
