Suning followed Yi Qingxuan and moved forward step by step.

Yi Qingxuan seems to be very familiar with the inside of the submarine, and the old horse walks inside as if he knows the way, and every place that is easy to touch will remind Suning to let him be careful, while Suning deepens his confidence in her, he can't help but have some doubts, how can she know so clearly, what her family is doing.

Of course, if Su asked her, with Yi Qingxuan's surname, she might tell Suning the answer. However, it's not necessarily good to know too much beyond your means.

He held up the torch and silently followed.

The inside of the submarine is not big, and after inspecting it, Yi Qingxuan stopped, thought for a while, and said:

"There is no doubt that the R3-4 class submarine has just taken a cursory inspection, and the structure of the submarine is not a big problem, and the problem should be the transmission system."

"Is there a way?" Suning asked.

"It's hard to say for the time being, let's see the situation first."

While speaking, Yi Qingxuan led Suning back to the submarine wheelhouse, turned a mechanical shaft in the wheelhouse, and then listened carefully to the sound of the bearing.

After listening for a while, he changed to another bearing, and at the same time asked Suning to raise the torch high to see if the upper part of the mechanical shaft was rusted.

After repeating this, all the four mechanical axes of the cab were rotated again, and Yi Qingxuan stopped.

Under the firelight, Yi Qingxuan frowned and said:

"I checked just now, there is still a lot of diesel in the tank, but when I started the diesel engine just now, there was no response, and there was no sound from the compression valve, I suspect that the transmission device caused by the design flaw is stuck, unable to push the valve to compress the air, and then unable to use the diesel."

"Can it be solved?"

Yi Qingxuan didn't nod or deny it, just motioned for him to follow, walked to the back, opened a valve, took out a series of things such as the welding gun and welding machine, the protective mask, and handed it to Suning.

Then the two of them took a set of tools for the welding machine and went out of the submarine.

"What's going on?" Suning couldn't help but speak, and from Yi Qingxuan's eyebrows, he had a bad premonition.

Yi Qingxuan didn't hide it, and said the doubts and difficulties in her heart.

"Yes, I can fix the drivetrain, but there is one thing that I need a welding torch. The problem now is that if you can't start the diesel engine, there will be no electricity, and if there is no electricity, the welding gun will not be used, and the welding gun will not be used, and I will not be able to repair the transmission system that ignites the diesel engine. Do you understand? ”

Suning was stunned, an endless loop! It's an endless loop!

The three are interlinked and indispensable, igniting diesel fuel can generate electricity, electricity can use welding guns, welding guns can repair transmission systems, and diesel fuel can be ignited.

What can I do about this?! Suning was also stumped.

The way to unravel the loop is to find the source. What is the source of this loop?

Now in front of us, the first important thing is to repair the transmission system, the repair system needs to use a welding gun, the welding gun must be supported by electric energy, and the electricity must be diesel to start.

Obviously, electricity is the source of the dead cycle, but only when the diesel engine is started can it generate electricity......

Wait a minute! Wrong!

A flash of light suddenly flashed in Suning's mind.

Who told me that only diesel engines can generate electricity anymore?! What if the source of electrical energy comes from outside? Isn't this endless loop unraveling?!

If you have electricity, you can use a welding gun, you can use a welding gun to repair the transmission system, and if the transmission system is repaired, you can ignite the diesel engine and start the submarine, and everything will be solved perfectly?!

Suning's eyes lit up, but then new questions followed.

Now they have nothing in their hands, where are they going to get electricity? It's not Lei Gong and Dian Mother, and the call will come when you shout.

Suning's thoughts, which had just been activated, cooled down again.

There must be electricity, where can we get it?

Suning paced unconsciously, and at some point, stood behind Qin Xiaoru.

At this time, Qin Xiaoru's expression was focused, her knees were bent, and the picture was on top of her knees, drawing a picture of the seascape during the storm.

And the physical prototype is the sea opposite her.

Suning just glanced at it and stopped paying attention. He is now full of thoughts about how to generate electricity, how can he have leisure and play a little romance.

Suning turned around, and the moment he turned around, the picture seemed to freeze!

He saw something that Qin Xiaoru was drawing, and the appearance of this thing almost made his soul tremble.

But it was very strange that he couldn't remember how he thought about it, as if the light was ahead, and he was just one foot away.

"What did you draw?!" Suning was extremely excited.

Qin Xiaoru was startled by the voice coming from behind her, the brush in her hand was crooked, and her original beautiful posture was completely destroyed by this sudden stroke of genius.

Qin Xiaoru waved her small fist angrily.

Seeing that Qin Xiaoru didn't reply for a long time, Suning had to endure the surname and asked again.

"What were you just drawing?"

"It's a deep-sea electric eel, it's a big one, haven't you seen it before?" Qin Xiaoru asked strangely.

Right! Eel! Suning's memory flashed in his head! There's nothing wrong with electric eels! Isn't the power generation expert I was looking for an electric eel?

With the electric energy of the electric eel supplied to the welding machine, there is absolutely no problem in repairing the transmission! All you need is a voltage regulator in the middle!

But here comes a new problem, there is an electric eel, but you have to attract it to come and discharge, this cave has nothing but submarines and dark rivers, how to attract it to come?

Suning had to desperately stir his brain, check his memory, and in Xueba's memory, he really let him find a useful piece of information.

It was a report of biological science research results in the next few decades, and in the report, it was mentioned that feline urine and rodent feces could be mixed together to form a new substance, which was ineffective against humans and other animals, except for electric eels!

Just as an addict sees opium and a shark smells blood, electric eels are as hungry and thirsty for this substance as the latter, and a drop of electric eels will gather for several kilometers.

Regardless of whether it can be done or not, you can try it anyway.

However, in terms of raw materials, feline urine, Suning just has a bottle of tiger urine on hand, and the tiger is a feline, so this is not worried. But there's another one, where to find rodent droppings? There are no rats here!

Rodent! Rodent! Suning forced himself to calm down, and as soon as he calmed down, he could figure out a lot of ideas.

Rats can't do it, but what about rabbits, the rat's close relative? Rabbits also belong to the rodent family to some extent!

Didn't Qin Xiaoru happen to have a rabbit there?!

How do you know if you don't try?!

Suning was in high spirits, and immediately told the second daughter about his considerations, as for mixing the urine of the tiger and the feces of the rabbit, Suning explained that it was a home remedy seen in the book, and the second daughter didn't ask much.

There is a way, everyone is very excited, Qin Xiaoru brought the rabbit down early, she doesn't leave the rabbit now, she didn't think that she saved the rabbit at the beginning, this will be thanks to Uncle Rabbit to save everyone's seven lives.

Go back, say anything, you have to give it to Uncle Rabbit.

Everyone prepared separately, Yi Qingxuan took out the voltage regulator, connected the welding machine, and carried the welding torch into the submarine, ready to start work at any time.

Suning went up the cliff, got a pile of hay and dry sticks, and then connected one end of the regulator to the thickest stick, ripped off the tape wrapped around the wires, exposed the bare wires, and tied them to the sticks.

Qin Xiaoru picked up the hay that Suning brought back, fed Uncle Rabbit hard, and urged.

Everyone's lives are in the hands of Uncle Rabbit, Uncle Rabbit does not drop the chain at the critical moment, and after a while, he will urge out a few black rabbit feces the size of a grain of rice.

Qin Xiaoru was so happy that she hugged Uncle Rabbit and kissed him fiercely.

Suning didn't dare to slack off, poured a few grains of life-saving rabbit feces into a vial containing tiger urine, and gently shook it a few times to accelerate the dissolution of rabbit feces.

When it was completely dissolved, the dark yellow was easy to turn into light red, and Suning walked to the dark river, carefully dripped one drop, and then seemed to feel unsafe, and dropped two more drops.
