Ten minutes later, the fire in the stove was already very strong, and the female soldiers guarding the No. 3 cave could even feel that the ground was hot.

On the stone above Cave 3, the meat skewers are already steaming.

The mountain rat is very fat, and the meat is a bit like pork belly, fat and thin, so although it is not oiled, it is not mushy.

Tian Guo and the others were hurriedly turning over the meat skewers, and they had even forgotten the fear when they saw this group of mountain rats for the first time.

"The anthrax virus is killed after ten minutes of cooking at high temperatures, so now these meat skewers can be said to be very safe and can be eaten."

Chen Feng looked at the female soldiers and said with a slight smile.

"Really, really?"

When it came to eating, Tian Guo couldn't help it, picked up a skewer of meat, put it to his nose and sniffed it.

"Wow, it smells so good!"

Tian Guo couldn't help but shout and grunted his saliva.

"I'll smell it, too."

Qubi Azhuo also reached out and picked up a meat skewer, "It's really fragrant!" ”

They rarely eat rat meat, so they have never smelled this fragrance, and it is obviously different from mutton skewers and the like.

"Well, it's delicious! Burnt on the outside and tender on the inside, it tastes like a numb sensation, and this taste has never been tasted before. ”

Tian Guo swallowed his saliva, bit off a meat skewer, swallowed it after a few bites like a jujube, and then nodded in praise again and again.

"I'll taste it too!"

"I'll taste it too!"

With Tian Guo, the first person to eat crabs, the rest of the female soldiers couldn't help it, coupled with the temptation of the fragrance, they couldn't bear it anymore, and they reached out to grab the meat skewers and ate them in a big gulp.

The Thunderbolt Commando on the side couldn't help but swallow their saliva when they saw the female soldiers eating so deliciously.

To tell the truth, they had eaten the meat of the mountain rat many times, but each time it was eaten raw, and they had never eaten it roasted, and they also had the urge to taste it.

"Hey, Thor, would you like to try it?"

Tan Xiaolin picked up the meat skewers, took a bite, and then looked at Lei Zhan and asked.

She didn't mean to be ridiculous, but really asked the other party if they wanted to taste it together, but the Thunderbolt Commando only had to swallow saliva at this time, so how dare she go up and eat it.

"Thor, this stove doesn't look special, why is there no smoke coming out?"

The old fox couldn't help but look at Lei Zhan and asked.

After waiting for a long time, the female soldiers have eaten, and the smoke detectors have not yet called the police, if it weren't for the fact that these smoke detectors were brought by Yuan Bao and Hades, I am afraid that the thunder and lightning commandos will wonder if they are broken.

"The smoke detector was personally debugged by me and Hades, so it's impossible for it to break."

Yuan Bao and Hades glanced at each other, also with puzzled expressions.

"Could it be that those two strange bamboos can have the effect of dispersing smoke?"

Da Niu said with a deep gaze.

"Yes, the problem is with those two bamboos."

Lei Zhan finally spoke at this time, he had been staring at the two bamboos the whole time, and finally saw some clues.

"Even if the two bamboos play a role in exhausting smoke, where does the smoke go? Can it still disappear into thin air? ”

After hearing Lei Zhan's words, the Raiden Commando was even more puzzled.

"Smoke is not actually a gas, to be precise, it should be considered dust particles, but because it is lighter than air, it can float in the air in the presence of hot gas."

Lei Zhan stared at the bamboo and explained to his teammates.

"Thor, we all know what you said, but how did the situation in front of us come about?"

The old fox and the others still looked puzzled and asked.

"Most of the particles in the smoke are actually soluble in water, and the rookie deliberately soaked the two bamboos just now, so that when the smoke is discharged through the bamboo, it can be absorbed by the water and attached to the inner wall of the bamboo."

"The amount of smoke that can be adsorbed on the inner wall of bamboo is limited after all, and the smoke that is not adsorbed is absorbed by the river water when it is discharged from the last opening, and even the hot air meets the cold river water, it will instantly cool down, and the particles have no effect of hot gas, and naturally sink and fall into the river water. In this way, neither smoke detectors nor the naked eye can be observed. ”

Lei Zhan took a deep breath and explained the phenomenon he had observed to everyone.

The female soldiers were eating happily at this time, the mountain rat meat had already been divided and eaten, Tian Guo, Shen Lanni and a few others were still unsatisfied, and they put the grasshopper skewers on the stone, and roasted them with the oil from the mountain rat meat.

"Hey, cook, I remember that there was no salt in these meats, why did they taste like salt? And it tastes pretty good! ”

Shen Lanni sucked her fingers and asked Tian Guodao.

"Hey, as soon as you said that, I also found out that there was indeed no salt, why did it have a salty taste?"

Tian Guo was reminded by Shen Lanni like this, and he was immediately confused.

"And it's amazing that the meat roasted on the stone doesn't have a single bit of sand mixed in it, and the meat quality is not affected in the slightest."

Ouyang Qian and Tang Xiaoxiao followed and spoke.

"Could it be that it has something to do with this stone?"

Tan Xiaolin said, glancing at Chen Feng.

Only then did she realize that Chen Feng had spent a long time trying to fish out this stone from the bottom of the river, which might have a deep meaning.

"This stone is called sandstone, which is a product of volcanic eruptions, and it is rich in salts, and it has been soaked and washed by the river bottom for hundreds of years, so it can provide us with salt in the wild and avoid the incorporation of sand."

Chen Feng looked at Tan Xiaolin and the others, and explained with a slight smile.

"Huh! The theoretical knowledge of military cadets is rich, and it actually involves our knowledge blind spots! ”

After listening to Lei Zhan's words, the old fox suddenly sighed with emotion, coupled with the fact that Chen Feng had just explained the magic of this stone to the female soldiers.

"No, this is not as simple as theoretical knowledge, I vaguely remember that I seemed to have mentioned this method of building a marching stove in an art of war before, but at that time, I was looking at a fragment of the book, and the recording method was not complete, but only mentioned these materials for building a stove, but there was no specific method, how did this kid learn it?"

Lei Zhan's eyes flickered, and he finally remembered that he had seen the information about this kind of marching stove before.

"Bang Bang!"

"The thunderbolt commando is really powerful, this kind of marching stove comes from the creation chapter of "Zhuge Art of War", I didn't expect such an ancient secret method, the thunderbolt commando team has been involved, it really impresses me."

Chen Feng clapped his hands and walked over with a smile on his face.
