Section 588

"OK, before we formally suture the wound, we must first perform high-temperature disinfection on the wound to seal the damaged tissue--"

"Because of limited conditions, I have to use a very old battlefield first aid method to treat my back injury. First of all--"

"Because it is bloody enough, it may cause discomfort. Friends with poor psychological tolerance must watch it carefully..."

That's all.

The audience in the live broadcast room vaguely smelled a different smell and suddenly became noisy!

"Fuck, what's going on?"

"What is Yu Shen doing?"

"Watch carefully? Is it that scary?"

"Again?"

"Don't enter if you are timid!"

"It's so scary just to hear it. What is this little brother doing?"

"Without saying anything, prepare the quick-acting heart-saving pills first!"

"Brothers, my heart is beating so fast!"

After taking a look at the barrage, Lu Yu took a breath and continued:

"In the era of cold weapons, due to limited medical level and years of war, the ancient Roman soldiers who were mixed in the battlefield once invented a very extreme method of heat treatment of wounds. They used hot metal weapons to directly weld the huge wounds to stop bleeding quickly when they were seriously injured!"

"This method of healing, which sounds extremely cruel, was still widely used until the birth of modern medicine."

"Although it was not so extreme later, many times, soldiers still used this method to disinfect wounds to prevent infection..."

At this point.

The audience reacted immediately!

As if they understood something, they all posted comments:

"Host! Is this what you call disinfection?"

"Excuse me..."

"Fuck! Do you want to..."

"Fuck, this is probably the rhythm of torturing yourself!"

"Fan No. 1 quit the group chat!"

"I've already thought of that scene!"

"Host, I respect you as a man!"

"You are so cruel to yourself, I can't afford to offend you, I can't afford to offend you..."

"You are so awesome!"

...

The ancient Roman first aid method is rough enough, but it has a very good effect in stopping bleeding.

The only drawback is that scars will be left after the wound heals.

But compared with staying alive, scars are really nothing.

While everyone was talking about it.

Lu Yu had already shown the copper axe and put it on the fire to bake.

"In fact, He has many ways to disinfect wounds in the wild. High-temperature roasting is only the most extreme and effective one. If you think this is too cruel, I have another method for reference."

"And I guarantee that as long as you are a normal person, you should be able to accept it unconditionally. You can guess what it is..."

After Lu Yu finished speaking, the audience immediately became interested.

The barrage floated one after another.

It neatly covered the entire screen.

But after looking around, he found that none of them could hit the point.

So, he shook his head and said with a smile:

"It's urine."

"Of course, the urine I refer to here is not ordinary urine, but fresh urine produced when the body functions completely normally."

"If it is a state of long-term dehydration, the urine produced by the body can not only not be used for disinfection, but will induce various unexpected dangers."

"Although fresh urine is sterile, it also has risks. It can only be tried in extremely urgent and necessary situations."

At this time, an audience asked Lu Yu, in this case, why not use urine for disinfection?

Lu Yu smiled and explained:

"I have survived here for two months with all my strength, and all my body functions have suffered varying degrees of damage. Urine contains a lot of impurities and bacteria, and it cannot be used at all. If you really apply it to the wound, it is almost the same as seeking death."

"So, everyone must remember that the premise of using urine to disinfect the wound must be that the body characteristics are completely normal."

While speaking.

The copper axe in the flame has changed slightly after being baked.

The next second.

When Lu Yu removed the axe blade from the flame, wisps of green smoke floated out in an instant.

It seems that the temperature should not be low.

I really don't know what will happen if I put it on the wound...

Soon.

After everything is ready.

Lu Yu held the axe handle with his backhand and placed the heated axe blade above the wound.

At the same time, he controlled the drone and let the camera point to his back.

At this moment, through the live broadcast, the audience can clearly see that under the light of the fire, the crack of the wound with pus flowing out has been extending from the middle of the spine to the right waist.

It is more than ten centimeters long!

The scar is as good as the sight, and it makes people feel cold.

If you really put the hot copper axe on it, the sizzling sound must be self-evident!

The next second.

Before everyone reacted from the shock, Lu Yu said:

"OK, brothers..."

"Next, it's time for another test!"

As the words fell.

Accompanied by various barrages, Lu Yu responded and put the copper axe on the end of the wound on the back of the waist!

"Zi——!"

The next second!

When the hot axe blade came into close contact with the wound, bursts of sizzling sounds were heard immediately.

In the silent night, it was very real!

Then.

The steaming hot air slowly rose from the skin, mixed with severe pain, constantly paralyzing Lu Yu's nerves!

Pain.

Heart-piercing pain.

Unbearable pain!

At this moment, even though Lu Yu had clenched his teeth.

But the burning pain from the wound still made him shout:

"Ah——!"

Accompanied by a low, hoarse, and even heart-wrenching roar, Lu Yu's breathing became rapid.

At this moment.

Because the drone's camera has been pushed to the extreme.

Through the live broadcast screen.

The audience can clearly see the subtle changes in the skin and flesh at the wound!

It took only three or five seconds.

The exuded tissue fluid disappeared after encountering heat.

At the same time, the scars that were originally torn apart were also closing rapidly at a speed visible to the naked eye!

But because the wound was too deep, it could not be completely healed by this method.

Therefore, after cleaning the brown fat liquid, proper suture must be performed.

"Ah...hiss..."

After the pain.

Lu Yu breathed rapidly and smiled at the camera with sweat on his forehead:

"It feels great..."

"But to be honest, this is definitely the craziest thing I have ever done in my life..."

"However, my injury is too severe and cannot be healed by heat treatment alone. This is just the first step. More exciting things are still to come..."
