The laceration wound on the back is deep.

The skin that bloomed on both sides has deteriorated severely.

It is difficult to achieve healing by relying only on one's own immunity and the self-healing function of tissue cells.

Even if the bandage is tied, it is extremely difficult to close.

Secondly.

Due to the prolonged soaking, the recoiled adipose tissue is already faintly visible at the wound site.

Although there is no sign of the bones being exposed, at first glance, the depth of the wound has long been more than six millimeters.

If you don't have a stitch, the consequences are really unimaginable!

The purpose of suturing a wound is simply to force the skin to close together to help the wound heal.

It's very simple medical knowledge.

Injured stitches, it's not a big deal.

Because after applying anesthetic, almost all the pain can be shielded.

But judging from Lu Yu's current situation, such a thing can not be said to be shocking!

There is no anesthetic, no professional medical equipment, and even the sewing tools are extremely rudimentary!

Stitch the wound with a bone needle!

Are you sure this isn't a joke!?

In the live broadcast room.

After listening to Lu Yu's words, the audience's eyes widened in an instant, and they put on an unimaginable look!

"I'm going to make it, Feather God, are you serious?"

"How much it hurts~!"

"You're not kidding, are you?"

"It hurts to think about it!"

"It's unimaginable, it's crazy...... If you don't use anesthetic, it will cause severe pain and the work of stitching cannot be completed!"

"Can you stand it without anesthetics?"

"Anchor, I respect you as a man!"

"it!"

Rumble!

The barrage exploded all at once!

Everyone was frightened by Lu Yu's bold idea!

They all said that if you are a normal person, I am afraid that you will not be able to stand this extremely barbaric self-surgery!

What does it mean to suture without anesthetic?

To put it mildly, this is masochism!

The pain of a bone needle going through the skin.

Just thinking about it makes people feel unbearable!

It's really incredible......

In the face of the audience's shock, doubts and worries, Lu Yu explained weakly and softly:

"Brothers, I don't want to ...... like this either"

"But in order to survive, I have to do it, and the wound is very deep, and if it is not sutured, it will be more difficult to follow. Because if the infection becomes inflamed, it will probably kill me!"

"In addition, because the wound is located in the back, which supports the body's core energy, even a slight movement of the limbs can cause the wound to expand or repetitively tear. Therefore, in any case, suturing is imperative......"

Between words.

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

Then he endured the pain again and took off his straw coat:

"A lot of people think that this kind of self-suturing surgery would not have been possible without specialized medical equipment. ”

But that's not the case. ”

"As early as the Neolithic period, intelligent hominids began to perform simple surgical procedures...... According to the archaeological evidence of the skull, the first 'ring drilling' can be traced back to around 6000 B.C., for the head injury, many primitive tribe shamans and priests, will use stone drills, drill open their heads, to reduce the pressure in the skull......"

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

To this day, gypsies who roam the wilderness still use this method to suture wounds, and the effect is very effective...... After all, long pain is better than short 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 show.

The deterioration of the wound is beyond imagination.

Although the bleeding has stopped.

However, due to the varying degrees of contamination of the wound, the adipose tissue fluid flowing out became more and more concentrated.

Blood stains and yellow fluid remain on the skin.

It looks very disgusting.

If left untreated, it is likely to cause other complications.

"It hurts to watch!"

"Oh my god......"

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

"The anchor is really NB......"

"Doing surgery on yourself is amazing, my brother!"

"It doesn't feel like there's a sassy operation he won't?!"

"Extreme Da Vinci!"

"Come on, anchor!"

……

After glancing at the barrage, Lu Yu went straight to the point and said:

"Before the formal stitching, I'm going to start a fire anyway......"

"There are a lot of stranded branches on the beach. ”

"Although it was wet, it should be possible to find some usable materials for starting a fire. Of course, it's not realistic to start a fire in a humid environment with these things alone, and we have to try to dig up some palm cores......"

The core of the palm tree has excellent qualities.

It is a rare first-class ignition material.

Because it is deeply encased in the bark, it remains dry even in extremely humid environments.

As long as the embers are drilled out of the drill plate, a fire is bound to start.

There are a lot of palms growing on the shore of the camp, and it is not difficult to get the core.

It didn't take long for Lu Yu to find a suitable dry core.

Followed by.

He also collected some relatively dry firewood on the beach.

And among them, I found a wooden plank with enough dry inside and a branch of proper thickness.

It is prepared to rely on the principle of frictional heat generation to create embers.

Relight the core.

Not much.

Everything is ready to go.

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

Then, he held the stick in both hands and stepped on the drill board with his foot.

Try to move up and down little by little.

Since the wood is not soaked for a long time.

The interior is still dry.

It took less than ten minutes for wisps of green smoke to float out from the lower end of the drill pipe and break into the live broadcast screen.

Looked at.

Lu Yu suddenly came to his senses, and in one fell swoop, he accelerated the frequency of pushing and pulling the wooden stick.

With the drill pipe, he kept rubbing the drill plate.

Outcome.

Don't lose sight.

As the frequency increases, so does the embers on the drill plate.

In less than ten minutes, the light of the fire flashed in the sea breeze.

Seeing this scene, Lu Yu hurriedly put down the drill pipe and poured all the embers on the core of the tree prepared in advance, and carried out the final blowing to support the combustion!

Soon.

When the dry core is heated, smoke rises in an instant.

In just a few seconds, it was ignited......
