Lu Yu carefully removed the bone needle from the animal bone chain.

Then he endured the pain and took off his straw clothes:

"Many people believe that it is impossible to perform self-suturing surgeries like this without professional medical equipment."

"But the fact is, that's not the case."

"As early as the Neolithic Age, intelligent primitive people had already begun to perform simple surgical operations... According to the skull evidence discovered by archaeology, the earliest 'trepanation' can be traced back to around 6000 BC, which was used to treat head injuries. Or, many primitive tribe wizards and priests will use stone drills to drill open their heads to reduce intracranial pressure..."

"In addition, due to the invention of bone needles and suturing technology, the survival rate of patients with severe trauma has been greatly improved. The specific method is very simple - in fact, it is to use bone needles with mulberry thread to suture the wound. The mulberry thread It can be completely absorbed by the human body, and there is no need to remove the stitches even after the wound is completely healed.”

"To this day, Gypsies traveling in the wilderness still use this method to suture wounds, and the effect is very effective... After all, long-term pain is not as good as short-term pain..."

soon.

After removing the extra clothes on his body, Lu Yu completely exposed the wound on his back.

At the same time, he controlled the drone and showed the audience an all-round view.

The severity of the wound was beyond imagination.

Although the bleeding has stopped.

However, as the wound surface has been contaminated to varying degrees, the adipose tissue fluid flowing out is getting thicker and thicker.

Traces of blood and yellow liquid just stayed on the skin.

It looks very disgusting.

If left untreated, other complications may occur.

"It hurts to look at it!"

"Oh my God……"

"If it were me, I would probably die on the spot!"

"The anchor is really awesome..."

"I performed the surgery on myself, my brother is amazing!"

"It feels like there's nothing cool he can't do?!"

"Extreme Da Vinci!"

"Come on anchor!"

After taking a look at the barrage, Lu Yu went straight to the topic and said:

"Before the official stitching, I have to light a fire first no matter what..."

"There were a lot of stranded tree branches on the beach."

"Although it is very humid, we should be able to find some usable fire-making materials. Of course, it is not realistic to light a fire in a humid environment relying only on these things. We also have to try to dig out some palm tree cores... …”

The core of the palm tree has excellent properties.

It is a rare first-class fire starter.

Because it is deeply wrapped in the bark, it can still stay dry even in extremely humid environments.

As long as you use a drill board to drill out the embers, you're sure to start a fire.

There are many palms growing on the shore where we camp, and it is not difficult to obtain tree cores.

After a while, Lu Yu found a suitable dry tree core.

Immediately afterwards.

He collected some relatively dry firewood on the beach.

And among them, he randomly found a wooden board that was dry enough inside and a branch of appropriate thickness.

Prepare to rely on the principle of frictional heat to create embers.

Then light the core.

Not long after.

everything's ready.

Lu Yu piled the firewood neatly on the beach, and then put the collected tree cores aside for later use.

Then, he held the wooden stick with both hands and stepped on the drilling board with his feet.

Experiment, moving up and down little by little.

Because the wood soaking time is not long.

The interior is still dry.

In less than ten minutes, wisps of green smoke floated out from the lower end of the drill pipe and broke into the live broadcast.

See this.

Lu Yu suddenly became energetic and increased the frequency of pushing and pulling the wooden stick.

Swishing the drill pipe, rubbing against the drill plate.

result.

Not disappointed.

As the frequency becomes faster and faster, more and more embers accumulate on the drilling board.

In less than ten minutes, dots of fire appeared in the sea breeze.

Seeing this scene, Lu Yu hurriedly put down the drill pipe, poured all the embers onto the prepared tree core, and blew it up for the final time to support the combustion!

soon.

When the dry tree core is heated, thick smoke suddenly rises.

It only took a few seconds to be ignited...

soon.

Another three to five seconds passed.

As the flames grew bigger and bigger, the tree core in his hand finally burned completely.

See this.

Lu Yu hurriedly covered the fire with his hands.

Carefully place it into the firewood you prepared earlier.

It wasn't until the fire dimmed and brightened that he slowly said:

"These branches are the best fire-making materials I can find so far."

"But it is foreseeable that due to the serious moisture on the surface of the firewood, the fire will not be very large. It is basically impossible to use it for heating. It can only temporarily relieve urgent needs."

While talking.

A faint fire finally lit up in the pyre.

It adds a different color to the dark beach.

Full of endless loneliness.

Late at night.

The wind at the beach is getting stronger and stronger.

at the moment.

Although the fire was lit, the fire was extremely unstable.

In order to prevent it from extinguishing, Lu Yu could only use his body to protect the fire, while carefully blowing air to help it burn, while using his body to block the all-pervasive sea breeze.

Don't let this only light of hope be shattered.

Because it is really not easy to start a fire in this environment.

Very quickly.

Five minutes later.

When the fire stabilized, Lu Yu finally breathed a sigh of relief, panting and smiling at the camera:

"Huh! Brothers..."

"It's really not easy..."

In front of the camera.

Lu Yu was covered in dirt and bruises.

The only smile left, although it looked powerless.

But it still gently overflowed under the light of the fire.

The contrast was extremely strong.

Many times.

Survival is like this.

Surrounded by enemies, there is no way out.

Even a small achievement can make the survivors feel deeply gratified.

Staring at the faint fire in his sight, Lu Yu's face was serious, as if he was thinking about something.

It took a long time to come back to his senses.

Then.

Pull back the thoughts that were walking away.

Lu Yu changed the subject:
