Ma Yuanliang raised his left arm, revealing that he was wearing a watch, and pointed to the time on it, which means very clearly, it will not be long before everyone's biological clock will come to the time of rest, and there will only be one or two people responsible for guarding at that time, if there is an accident at that time, it will be difficult to deal with it.

The best choice now is to find a way out before everyone's energy weakens, hard work may not necessarily be rewarding, but if you don't work hard, there is nothing, whether there are dates or not.

Everyone speculated on the pros and cons of that method, the advantage is that you can intuitively and clearly observe the landform here, and the disadvantage is the possibility that Xu Mengyi said.

Cheng Feng returned to the riot control vehicle, pointed the spotlight on the roof of the car obliquely at the height in the center of the city, roughly estimated the volume of this confined space, and analyzed the amount of oxygen stored in it.

"Captain, shall we do it or not?" Liu Jiandong asked.

Ma Yuanliang looked at Xu Mengyi, who was standing diagonally to the right, and asked, "What do you say?" Big star. ”

"This, this ......"

Xu Mengyi didn't say anything for a long time, he wanted to say nothing, but now he has to take care of Ma Yuanliang's leadership position, and it's hard to refute.

Chen Feng got out of the car, walked up to everyone and said, "I have roughly calculated the oxygen content of this place, which is enough to support the burning of those withered plants, if possible, we can find the direction of the smoke to find the exit, if it is sealed, we must prepare for smoke prevention in advance."

Ma Yuanliang nodded, agreed with Chen Feng's proposal, and asked everyone if there was any possibility of appearing.

"This place has been on fire before, will it be disrespectful to those people?" Xu Mengyi still couldn't help but say.

The living breathe, the dead rest in peace, and the respect that should be there still needs to be there.

Liu Jiandong proposed: "Let me give them the scriptures, I think they should not embarrass us."

If the scriptures were useful, they wouldn't have been chased by the ghosts on the road, and there was still no unanimity of opinion.

Ma Yuanliang took a piece of rune paper, tore it into two parts, one large and one small, kneaded them into two small paper balls, grabbed them in his left and right hands, and said: "Come on, draw lots, if you catch the short one, you agree to set fire, and if you catch the long one, you agree to set fire."

The others were stunned after hearing Ma Yuanliang's words, and Chen Feng stood up and asked, "Company commander, did you say something wrong?"

Ma Yuanliang hurriedly shook his head and said, "Catch it."

What else is there to catch here, the results are the same on both the left and right.

Everyone had nothing to say, glanced at Ma Yuanliang speechlessly, and returned to their cars one after another, there was nothing more to say, just do it.

"Why are you leaving?"

Ma Yuanliang glanced at his lips, returned to his car and shouted, "Let's go!"

Four black riot trucks lined up on the road, slowly moving from south to north.

After the riot truck drove a hundred kilometers, Ma Yuanliang gave an order: "Dongzi and I are in charge of the west, Chen Feng, you and Xu Mengyi are in charge of the east."

Suddenly there was a rapid firing sound on the roof of the car, and the thumping sound was like a musical note with a sense of rhythm, followed by the ensuing explosion of thunder, which felt like a drum in the car, not so harsh.

The grenades that fell to the ground blasted out balls of fire, and burst into golden sparks, dazzling and dazzling, and the lawns and street trees behind the convoy within range were ignited, and the flames burned with an eerie red glow.

The fire moved north with the riot control vehicles, and it also spread in the east-west direction, and the speed was not very fast.

Ma Yuanliang stared at the fire outside the window while driving, the light was still not enough, and it failed to illuminate the sky above the city, so he couldn't help but speed up the car, preparing to ignite more before the fire that burned first was extinguished, and shouted with the walkie-talkie: "Brothers, work hard!"

Everyone stepped on the launch switch of the grenade, and the positioning that could not be aimed was supplemented by the dense firepower, causing fierce fireballs to bloom everywhere.

"Why be so violent."

Xu Mengyi, who was on the penultimate car, kept muttering, there was always a feeling of unsteadiness in his heart, praying that nothing would happen, shrugging his head, he couldn't bear to look directly at the scene outside the window, and finally caught the abnormality of the flames from the corner of his eye.

"I'll just say, you can't make a fire, you can't burn a fire."

Xu Mengyi opened the car window, poked his head out and looked behind the car in confusion, and sure enough, what he saw was not a normal flame, and turned his head to Ma Yuanliang, who was driving in front, and shouted: "Stop!" Stop the car! ”

The deafening boom kept ringing out, and the people sitting in the car couldn't hear the shouts outside.

"You, you"

Xu Mengyi reluctantly returned to the car, picked up the walkie-talkie and said, "Stop, stop, the situation is not right." ”

The convoy stopped in the central square, and the others got out of the car and walked to Xu Mengyi's side.

Ma Yuanliang knocked on Xu Mengyi's car window and asked, "What's wrong, big star, what's going on?" ”

Xu Mengyi sat in the seat, looked at the flames with a red glow from the rearview mirror, and thought that he definitely provoked something that should not be provoked, and he still had a sense of security in the car, so he reluctantly pushed the car door, moved outside, looked up at the flames behind the convoy and said, "This is not what my house fires look like." ”

Different colors of flames represent different temperatures, and the temperature of dark red flames is about 600 degrees.

Chen Feng didn't notice anything abnormal, and explained to Xu Mengyi the temperature of the ordinary fire. Liu Jiandong didn't understand Chen Fengjiang's scientific knowledge, but he just felt that it was very profound.

Ma Yuanliang stared at those flames, because he felt that something was abnormal, the color of the flames was a little strange, and he didn't think of it for a while, and said, "Let's go, let's take a look." ”

Xu Mengyi waited for them to walk out of a distance before following with a sad face, and regretted why he didn't stop them from setting fire, thinking of the saying "playing with fire"!

I walked more than ten meters and observed a dead tree that was burning.

The flame did not change color from the inside to the outside from the point of combustion, it was very simple red, pale and somewhat transparent, there was no smoke, and there was no charred black of the trunk.

If you look closely, the dead wood is not burning at all, but it is covered with a layer of flames, wisps of fire.

Ma Yuanliang and the others finally understood the abnormality that Xu Mengyi said, and they were dumbfounded, not knowing what to say.

"What now?" Xu Mengyi rubbed her face and asked.

You don't have to think about it to know that this is definitely not a fire from an object, and besides, whether it is a dead tree or an artemisia grass, it is still there intact.

Ma Yuanliang took out a piece of rune paper from his arms, leaned over and put the rune paper on the fire to grill, and a surprised scene appeared, the rune paper was not ignited.

"It shouldn't be a big problem, it's better that you don't have to worry about them going off, and you can be a good light bulb."

As he spoke, he reached out and touched those flames, since they couldn't even burn the rune paper, they definitely wouldn't have much temperature.
