The bamboo board was taken off the bonfire, still emitting hot smoke.

Bi Fang used chopsticks made from tree branches to pick up the fish belly residue on the oily surface and threw it into his mouth. It was extremely crispy and had a slight bitter taste.

After letting the bamboo board cool down slightly, Bi Fang picked it up with his bare hands and took out a can of boiling water and a few pieces of black charcoal.

"The most easily forgotten thing when traveling or surviving in the wild is soap. In fact, it is very easy to make soap in the wild, and it is very important to maintain hygiene, especially in life-or-death situations, cleaning wounds is very necessary."

Bi Fang has never made soap before. The reason is that he doesn't use it very much, and he doesn't need to socialize. He gets dirty when he gets dirty, and he doesn't see anyone.

But in the rainforest, it is very important to maintain personal hygiene. Uncleanness can kill people.

"There are only a few raw materials needed to make soap. The first is alkaline charcoal ash, the second is water, the third is oil, vegetable fat, animal fat, anything that can fly, swim, or run. Finally, if conditions permit,

Plus some antiseptic drugs.”

"Of course, the last item is not necessary. It is just to make the soap have antiseptic function and good smell. I can find pine needles and rosin in the forest, and I can use citronella in the rainforest."

"Citronella is not just a spice, because it contains citral, which has the effect of disinfecting, sterilizing and treating neuralgia and muscle pain, so it is known as the 'Pain Swordsman'. It can be used for abdominal pain, colds and fevers. It is equivalent to a regular

It is a tiger balm medicine for diseases, and it can even beautify your skin and is good for your skin.”

Bi Fang crushed the lumps of charcoal with stones, mixed the charcoal ash and water, and said: "Be careful not to stir it with your hands. On the one hand, it is very hot, and on the other hand, the charcoal ash is very alkaline, which may

It will burn the skin.”

After stirring thoroughly, filter out the charcoal ash and pour the water into the bamboo tube.

Then, while the oil has not yet cooled and solidified, pour it into the bamboo tube filled with water just now, and put the bamboo tube filled with oil and charcoal ash water back into the campfire to heat.

"Next we need to re-boil it to sterilize it, but there is still a little bit of oil left here, and we will definitely waste it. We can use it to make a plate of bamboo shoot soup."

Bi Fang peeled three of the bamboo shoots he had collected earlier. After peeling, the innermost part was still dripping with water.

"Bamboo shoots are fresh and tender food and cannot withstand storage and long-distance transportation, so there is no need for us to save, we can just eat as much as we want."

Bi Fang put the bamboo shoots into the semicircular bamboo tube where the oil had just been refined, added some water and continued to stew, with faint golden oil flowers floating on it.

Tear a large amount of lemongrass into pieces, then mash it and add it directly to the bamboo jar in the fire pit. At this point, the soap making process is basically over.

"If you don't need powerful soap, then you don't have to worry about the ratio of fat to charcoal water, because we can just evaporate it directly. When the water evaporates completely and waits for it to cool down, it will be a pretty good piece of soap that can remove stains.

There is also soap with antiseptic properties.”

[Hiss, I learned another trick, I can only travel through time and show off my skills in front of the natives]

【666, Eye-opening, eye-opening!】

"Just traveling through time may not be enough. You have to at least travel back before the primitive tribes, because even many primitive tribes know how to make this kind of soap."

"This is actually a misunderstanding that many people have. They think that people in primitive tribes must be dirtier than us. But in fact, in some primitive tribes that still exist today, hygiene is as important as in modern society."

Bi Fang saw the barrage and made a joke like the audience.

“Finally, a reminder, even if you bring biodegradable soap or shampoo, you must realize that they require soil to degrade, so in order to avoid contamination, we should dig a pit 25 meters away from the water source.

Pour all the washing water in."

While waiting for the water to evaporate, the grilled fish and fresh bamboo shoots are finally finished.

The originally golden fish skin has turned into a burnt yellow color. Although it is not as beautiful as before, it is more smoky and appetizing, and the faint lemon fragrance is wrapped in the burnt aroma.

Opening the cover of the bamboo tube, white smoke is rising, and the milky-white tender bamboo shoots are rolling up and down in the boiling water. Along with the faint smell of fish oil, there are also a lot of black ants sprinkled inside to add flavor, and they look like grains of black.

Sesame.

Bi Fang picked up one and tasted it. His eyes lit up. The crisp and tender texture exploded with the hot juice. He couldn't help but open his mouth wide to dissipate the heat, but he couldn't bear to spit it out.

There is a light astringency mixed with oily flowers. Although it doesn't have much flavor, you can still feel the sweetness inside.

Bi Fang quickly picked up a piece of grilled fish that was sizzling with oil. The unique aroma of lemongrass mixed with the unique sour and salty taste of formic acid enhanced the unique deliciousness of the grilled fish.

In particular, catfish itself does not have many spines, so one bite is very satisfying.

Bi Fang, who had not eaten all day, was drinking bamboo shoot soup, eating grilled fish, lighting a bonfire, listening to the rain hitting the plantains, and felt very comfortable.

Very beautiful.

Under the rain, there are fireworks far away from the world. If there are falling mint leaves in the soda water, everything will become fresh.

Bi Fang took a sip of the soup with a spoon and said happily: "The catfish is fat and has few spines, so it is suitable for roasting. The carp can be used to stew bamboo shoot soup. Tomorrow's food is also provided, and it needs oil to make it fragrant."

"The only fly in the ointment is that we don't have salt. Otherwise, if we sprinkle a pinch of salt on it, the taste will be more delicious. Tomorrow I will think of a way to see if I can get some salt. It won't work if I don't eat salt for twenty days. I will lose my strength."

of."

[Dooling, hehe]

【I'm hungry too, I want to eat too, woo woo woo】

[It’s already seven o’clock, and the takeaway I ordered hasn’t arrived yet, so I’m starving]

[By the way, are catfish really edible? The last time I saw a video, it was said that catfish grow up eating feces and garbage... their bodies are full of heavy metals...]

[Pfft, is it real or fake? I think Fang Shen is enjoying the meal]

Bi Fang swallowed the fish in his mouth. Hearing this truth during the meal ruined the atmosphere. He shook his head directly: "I don't know where you got this from, but it is not reliable and is very biased."

"First of all, from the perspective of feeding habits, catfish are carnivorous fish. Wild catfish mainly prey on fish smaller than themselves, such as crucian carp, carp, loach, etc. They will use their sense of smell to find prey, and then use their teeth to kill them.

Trapped and then swallowed.”

"If you really want to eat feces, it's not just catfish, but any fish will eat it, but feces is not necessarily what they eat."

"In rural areas, fish farmers in the early years should know that there were many fish ponds. If the pond was larger, the fish farmers would throw feces directly into it. This would stir up a big fish."

"That group of fish are eating deliciously and are vying for the first place. There are not only catfish, carp, grassroots, and silver carp in there, but all kinds of fish are there."

【Ah, this, I have seen this!】

[Plus, my grandpa’s house has a small fish pond. Every time I fish, I just pour hay manure on it, and all the fish come up at once. I catch the fish and eat them at night, and I’m still happy.]

Bi Fang went to a city in his previous life for work, and there happened to be a big smelly ditch near where he lived.

That guy's stench is astounding for miles around. It's no exaggeration. You can smell the stench from two miles away.

If it were just a smelly water hook, the problem would not be big. The problem is that it is a stagnant water pit. Not only the designated pit for nearby residents' sewer drainage, but also the wastewater from many factories is discharged into this pit.

The water has a very high viscosity, and when stirred, it can stick to the wall like milk.

It contains not only feces, industrial wastewater, various garbage, but also all kinds of smelly fish and rotten shrimps.

In the pond, there was no grass or any living creatures, but there was only one mysterious creature.

That's it - catfish, and a few catfish from other countries. Bifang couldn't recognize any species at the time, but the smelly ditch caused the prices of nearby houses to be low.

Once passing by by chance, Bi Fang saw an old man fishing there. He was shocked at the time. He stopped and looked at it. Within 10 minutes, he hooked a catfish.

More than one meter long, the fish is full of colors, ranging from green to black, and black to purple. It exudes a foul industrial smell, and has a terrible long beard. When you look closer, you can see that the fish is still deformed. The head is crooked, and the back end is still

the protruding.

None of this is important. What is important is that on the left side of the fish, there are a bunch of indescribable growths growing on the back. I don’t know what they are.

Bi Fang, who studies biology, saw for the first time the tenacious vitality of creatures, and for the first time knew the horror of mutation.

"So, catfish are really tenacious in their vitality. They can survive in no matter how dirty the environment is. But these are just a few. Moreover, all catfish in China have one characteristic, that is, they are clean."

"For example, the largemouth catfish in the south have extremely high requirements for water quality. Once the water is dirty, they will immediately turn over and die in front of you."

Bi Fang's words made the audience laugh, but they also understood.

Whether the fish itself is clean or not depends on the living environment.

As a natural river in the rainforest, it is naturally not too dirty, just slightly turbid, so there is no need to worry about eating it.
