As for Xia Baizhu, there is no shadow!

"I have done many live broadcasts before, some of which were only for a week. As long as I maintain my food intake, even though the sodium content is extremely low, there is still no problem if I don't take in salt. At best, it is psychological discomfort, and it is still a little far away from physical discomfort.

."

"Even if there are live broadcasts that last for 20 days or a month, they are either only at the beach and there is no shortage of sodium, or they often hunt large animals and can supplement enough salt with blood."

The audience nodded.

There was no shortage of salt when I was trying to survive at sea. Geese often flew over the sea during migration, and there were also large animals to catch, so there was no shortage of all kinds of blood.

This time it was a little bit worse.

It’s not easy to live without salt for twenty days. The simplest question is, why can the human brain control the body?

When a person wants to move a finger, the brain first sends an instruction, which is transmitted by the nerves. The transmitted nerve signals cause the finger muscles to contract and stretch, thereby enabling the person's fingers to move.

The conduction of nerve signals is determined by the potential difference between sodium ions and potassium ions entering and exiting nerve cells.

Without salt and sodium ions, even if your brain wants your finger to move, your finger won't receive the signal to move at all.

People will have symptoms such as listlessness and fatigue. In more serious cases, the limbs will be swollen, the body will be weak, the brain will be depressed all day long, and death will soon occur.

But the audience doesn't care about this at this time.

[Hurry in, hurry up, get to the camp quickly, and start smelting iron right away!]

"Don't worry, let's make a fire first, make a torch, and then go in. If the white-limbed bison can get in, it means there is basically no toxic gas inside, and it is suitable for living creatures to live or survive. There are likely to be bats in there."

Bi Fang took out the kindling and the tinder he had prepared in advance.

He stores these things in a funnel bag close to his body, just to avoid getting wet in the rain.

In the rainforest during the rainy season, you have to look for opportunities to get even dry tinder.

While lighting the fire, Bi Fang introduced: "Bats are probably the mammals that hate rain the most. Bats look bare on the surface, but they actually have fur."

"If a bat's fur gets wet, their body temperature will drop rapidly, and the water will affect their ability to fly. Even adult bats need to be kept dry all the time. So on heavy rainy days, bats will hide in caves and under trees."

"Now that the rain has just stopped, I feel like there might be a lot of bats squatting inside."

[Why must it be a bat? Could there be a bird inside? 】

【Can bats be eaten?】

【i am batman!】

【The Mystery of Heroes!】

[A Mr. Wayne emerges from inside! 】

"It's unlikely that the bird is in the cave." Bi Fang has successfully lit the torch, hollowed out a bamboo tube and put sand inside.

"Although birds have feathers, they are not actually afraid of rain. Most birds have oil glands. Birds spend a lot of time preening their feathers every day, which is to apply oil to their feathers, so their feathers

It’s basically waterproof.”

This is why ducks can play freely in the water without getting wet.

"Some birds will even take advantage of the rain to take a bath and clean their feathers. Only the chicks have not yet grown waterproof feathers, so heavy rain will be a disaster for them."

"Oh, and owls' feathers aren't waterproof either, so they don't usually hunt in the rain."

Bi Fang filled the bamboo tube with materials, and the process was exactly the same as preparing gas masks in the wilderness city.

Just replace the plastic bottle with a bamboo tube, and the inside is covered with charcoal ash, limestone and some sawdust.

Drill two holes with a stone knife, thread the hemp rope and wear it on his face. After everything was prepared, Bi Fang still did not drill into the hole.

The audience who had just prepared to watch Bi Fang explore the cave were almost anxious to death. It took you half an hour to go in!

Bi Fang chuckled. Who would be careless about his own life? He grabbed some wet dead branches nearby.

"We can smoke them with salt first and see if we can smoke them out."

【This is too stubborn】

【Are you also a Gou Daoist? 】

[I went and rubbed it at the entrance of the cave for half an hour, and my skin was all gone]

【What a fast car】

"Different woods have different burning properties. If you want to create a lot of smoke, moist dead branches are the best material."

He put the torch close to a large number of dead branches and after lighting it, a large amount of gray smoke evaporated. Bi Fang quickly entered the cave and ran out as quickly as he could.

Before he could run out of the cave, a large number of piercing screams echoed in the cave.
