I don't have a system but I have a hammer

As soon as he heard my words, his face suddenly burst into ecstasy, as if a primary school student who hadn't finished his summer homework suddenly received a gift from a friend three days before entering school. It was the answer to all the summer homework!

Even if the answer is wrong, at least for the person concerned, this is the only hope to get out of the predicament at the moment...

"You... what did you think of?"

I didn't reply to the gentleman immediately, but looked solemnly at the sharks in the distance, and then took out two bottles of gasoline from my tactical belt...

"Look at the sharks on the opposite side. There are a lot of dead bodies nearby, so we are safe for the time being, but there are too many sharks. I estimate that we will be the next target in 10 minutes at most, so I need you to help me with one thing. !"

The gentleman nodded in a flustered face, as if he was looking ahead...

With a serious expression, I poured gasoline around...

"Things that can repel sharks, one is copper sulfate, and the other is shark repellant. It is difficult for us to get the former, but we can find substitutes!"

I took out two waterproof bags from the tactical backpack, then slowly unfastened the tactical belt, took out a bottle of corrosion powder, and handed everything to him...

"Did you see the three pieces of copper at the connecting part of the belt? Use a knife to scrape them off, put them in a waterproof bag, then pour the powder into it, seal the mouth and give it to me..."

He took the tactical belt and corrosive powder nervously, for fear that they would fall into the sea...

Seeing him working hard, I nodded, and took out the fruit thorn from my pocket...

"Gasoline will evaporate quickly. Even if we find a substitute, it will only be temporary. The powder will be washed away by sea water immediately, so we have to make shark repellant on site!"

He looked at me blankly, completely unaware of how to make the shark repellant I mentioned...

I looked at the school of sharks and continued to explain...

"The core ingredient of the shark repellant is a biological gland fluid extracted from dead sharks. Because this gland fluid can transmit dangerous biological signals to their companions, sharks will specially avoid areas covered by biological signals!"

The gentleman suddenly realized, and looked at me with admiration...

"Of course, if the sharks are extremely hungry, they will ignore this signal. After all, even humans can cannibalize their own species, but with so many carcasses for rations, I believe this situation will not happen!"

I pointed to the sharks on the opposite side again, and a bloodthirsty light began to appear in my eyes...

"If my guess is correct, the gland fluid should be in the shark's pituitary gland, or secretory gland. That is to say, we must kill a shark so that we can survive until rescue!"

Now he understood what I was going to do, and his eyes were no longer admiration, but deeply shocked by my crazy idea...

I glanced at the waterproof bag in his hand, the surface of the copper sheet mixed with corrosion powder has turned slightly blue...

I know, that's the color that appears after the copper reacts with the acid in the corrosion powder...

"I... I'm done, what should I do next?"

Listening to the gentleman's trembling question, I licked my salty lips and narrowed my eyes slightly...

"The next step is to wait for the sharks to attack us. Of course, you can also choose to take the initiative..."

There was a flash of fear in his eyes, and he shook his head and waved his hands quickly, with a cowardly look of "I'm a little spicy chicken, or come here as a big brother"...

I patted him on the shoulder and smiled...

"Remember, once the shark approaches, tear off the waterproof bag immediately, because copper sulfate is a heavy metal salt, and when our substitute is mixed with salt in seawater, there is a high probability that it will be able to disperse the surrounding sharks!"

I took a waterproof bag from him, squeezed it tightly, and regained my serious expression...

"But at most ten seconds, or even a few seconds, the substitute will be washed away by the sea water, so in this short period of time, we not only have to enjoy the pleasure of corrosion, but also have to kill a shark and take out their glands. body!"

Then I seemed to remember something...

"By the way, have you found the locator? Hey...why didn't you respond, you were so scared?"

I frowned and pushed the gentleman who was still in fear...

After he reacted, his face was full of embarrassment...

"Looked... found it, but in the current situation, I don't know if we can last until then..."

i smile...

"According to 10 minutes, this group of sharks will have to eat for at least 10 minutes, which should be enough for us to survive until the rescue comes!"

After finishing speaking, I stuffed it into the breathing mouth with a blank face, and sank into the water with a puff...

After looking around and confirming that it was safe underwater, I surfaced again, looking at the blood-splattered sea in the distance, thoughtfully...

"Sharks take time to eat. Their way of eating is to take a bite of their prey first, and then decide whether to eat after knowing its nutritional content. If it is not beneficial to them, they will even leave directly..."

Wiping the cold sea water off my face, I laughed at myself again...

"But looking at the situation over there, this group of people is quite suitable for the taste of sharks. Of course... it is also possible that this group of sharks are really hungry, so they..."

Before my voice fell, my pupils shrank immediately...

"Here we come! Just two, one for each of us!"

I narrowed my eyes and looked at the sea in front of me, where there were two forearm-length shark fins, like a pair of extremely sharp triangular steel knives, cutting the sea water neatly, and slashing straight towards us...

"get ready!"

Looking at the extremely fast shark fin, I pulled out the navy knife, and my narrowed eyes suddenly opened, bursting out with the ultimate killing intent like a hell Shura...

Now I'll peel off your skins and make bathing suits!

There was a fierce flash in my eyes, I immediately put on the goggles, and sank into the sea with a puff...

I stared at the ferocious sea beast less than three meters away from me in front of me, tore open the waterproof bag, put the navy knife on the front and back of my chest, and took out the fruit thorn...

next second!

The corrosive powder scattered in the water, and I felt a tingling pain in my neck in an instant, but I didn't have time to pay attention to it, because the shark on the opposite side was already close at hand!

I can even see its black eyeballs and gills like a washboard...

Hope...a substitute works!

Maybe it was my prayers that helped, or maybe it was my bad luck that I had a holiday today, or maybe it was my will to survive that moved God...

Anyway...

The shark completely ignored the corrosion powder, and opened its mouth full of sharp teeth directly towards me within a distance of less than two meters!

But I looked calm, because... I already knew that the god of fate was going to play tricks on me again!

Decided to eat shark meat tonight!

Dry!
