"Cell phone?"

Han Xuening handed the old flip phone to Qin Fengyi.

The contents of the suitcase are estimated to be several years old, most likely brought to the island by shipwreck survivors, and never opened again.

The island's unique subtropical rainforest climate, the overall temperature has been very high, and the forest is hot and humid, the clothes in the suitcases are moldy, and some are corroded by moisture-bred bacteria, and the clothes become extremely damaged, and they will tear apart at the slightest touch.

All the clothes were scalded with boiling water yesterday, and then dried in the sun for a long time, relatively speaking, they became much cleaner, the only defect is that after boiling water, the clothes are somewhat faded and full of wrinkles.

"Hey, what are you doing with your phone?" Lin Qingxue's spirit became worse and worse, and she began to cough lightly.

"You can drink some water and sit here and rest for a while. Qin Fengyi tested the girl's body temperature with his hand again, "It seems to be getting hotter and hotter." ”

"I'm fine, just sit and rest. Lin Qingxue smiled reluctantly, sat down on the stone slowly, curled up and wrapped herself in a mosquito net.

"Mr. fire, with fire, you can boil water, and when you have a fever, drink more hot water to help sweat and detoxify. "Han Xuening's spirit is not very good, most of them are a little cold, but the overall mental state of the beautiful teacher is much better than Lin Qingxue.

"Well, I'll start a fire right away. ”

Qin Fengyi took the completely unusable mobile phone and removed the battery, the white battery was full of raised lumps, the battery power was not completely exhausted, and if you wanted to excite its power, you had to destroy it.

The mobile phone battery also contains some power inside, and when the battery is damaged, a short circuit will occur, and sparks will be emitted in contact with the metal, and the fire can be quickly ignited with the help of scorching sparks.

"Ahem...... ahem" Lin Qingxue coughed lightly, sniffed, and her voice was slightly hoarse, "It's just rained, and you can hardly find dry wood, so it's relatively difficult to make a fire." ”

It was difficult to make a fire in such humid weather, not to mention that the wood was wet, and the dull moisture in the air alone would prevent the flame from igniting.

"Wood is wet, but it's not necessarily damp on the inside. Qin Fengyi came to a large piece of driftwood in front of him, this piece of driftwood was almost a whole tree, and it was buried by the wind and sun and sand for a long time, and last night's heavy rain failed to wash the wood into the sea, and part of it was buried by sand.

This piece of wood has obviously been exposed to the sun for a long time, and the whole is a little loose, almost breaking at the touch of it, and using a saber as an axe, a section of wood is chopped off.

When slashing, you can clearly feel that the outer layer of driftwood is full of water, and the water droplets mixed with broken wood powder are splashed everywhere with a knife, but fortunately, a large piece of wood can be easily chopped.

Through the cutting layer, it can be clearly seen that the outer ring of this piece of wood is very dark, these are absorbent wood, but the inner layer is very light, these are dry wood.

Dry wood that has been soaked in water is indeed wet, but the inner layer is definitely dry, and only the damp part needs to be removed.

In less than a minute, a section of dry wood was harvested, which was cut into pieces with a saber, which could be used as velvet, and the rest was cut into small sticks to start a fire, and if the flame was grown, the damp wood could naturally ignite.

"We need bamboo to build a house, right?" Han Xuening was not idle during this period, and the beautiful teacher came to the periphery of the bamboo forest with a machete, ready to cut some bamboo.

"Teacher Han, I'll help you. Lin Qingxue didn't want to be a burden even if she was dizzy and groggy, so she followed Han Xuening to chop bamboo.

"Take a break, I'll do it later. Qin Fengyi looked at the two delicate beauties distressedly, after a storm, they were like weak little cats, their messy hair looked a little messy and beautiful, and it looked particularly sad.

"I have to do what I can, and I can't be a drag. Lin Qingxue turned around and squeezed out a smile, but the tiredness between her eyebrows could not be hidden, and then the girl coughed lightly.

"Hey!"

Qin Fengyi sighed slightly, the physical condition of the two girls is not good, this is a cold, if you are in the city, a little anti-inflammatory medicine and cold medicine will be fine for a few hours, but on a desert island, you can only resist hard.

The water gently pounded against the sand, and the murky waves pushed the floats, including wood chips and leaves, a few dead mice, a few small soft snakes, and in the distance a seabird, which seemed to be trying to drag the seabird into the water to feast.

Nature is cruel, a storm has taken many lives, and natural disasters of this magnitude are also deadly threats to humans, reducing people's resistance and slowly dying of illness.

The life expectancy of primitive people in the early days was generally very low, and 40 years old was considered a high lifespan, all because they could not resist the terrible laws of nature, and there were not enough hole cards to fight with them.

After tens of thousands of years of development and evolution, human beings have stood firm in nature, and the reason why human beings can become the masters of all things in the world is because of technology and medicine.

But after being on a desert island, technology and medicine have no effect, there are no hospitals, not even a single antibiotic pill.

However, Qin Fengyi has mastered a lot, he has lived in the countryside for 18 years, and he understands a lot of common sense, so he can go out to find some medicinal materials and see if there are any anti-inflammatory and fever-reducing medicines.

Tamarind in the fruit can reduce fever, however, the effect of anti-inflammatory is minimal, the inflammation is not eliminated, there will be repeated fever, the reason why people have fever is all because of their own inflammation, when the white blood cells in the body fight against inflammation, the brain will give an early warning, that is, fever.

"Woo~~!"

"Roar~~!"

Wangcai and Yayale couldn't stay idle, and watched Qin Fengyi fiddling with broken wood chips and small firewood, and suddenly surrounded him, wanting to see what was going on.

"You guys go and have time to help clean up the field over there. Qin Fengyi pointed to a sandy land in front of him that looked quite flat, with ravines on the ground and many broken stones.

"Woo~!"

Wangcai immediately understood, ran to the ground over there and began to dig through the damp sand with his paws, and then buried the ravine that had been blasted out by the rain, and Yayale followed suit.

If the pet is smart, it is easy to save trouble, and there is basically no need to tell some, and these two goods will do it immediately.

Now ready to make a fire, Qin Fengyi cut the battery with a saber, and the battery full of raised nodules emitted a sour smell like sulfuric acid, and then white smoke began to slowly appear, which seemed to form a short circuit, and then sparks began to slowly appear.

Cover the battery with velvet, and the flames will instantly engulf the velvet, and then quickly ignite the firewood.

"It's amazing, it really ignited the fire. Lin Qingxue and Han Xuening dragged a bamboo pole over with difficulty, the lowest end of this bamboo is 10 centimeters in diameter and more than 20 meters in length.

"There just happened to be bamboo, give me a piece of bamboo and I'll cook some medicine. Qin Fengyi took the bamboo, ready to cut off the bottom section of bamboo, but who knew that a knife would actually produce water.
