After eating a whole wild boar, Artoria's combat effectiveness was very terrifying, and a section of two or three kilometers long and ten meters wide was opened before dawn.

When she returned, she found that in addition to the night watchmen in the camp, Charles and Matsui Shimoishi were chatting happily about the customs of the mainland.

Matsui Shimoishi saw Charles greeting the returning Dull King, so he said very well that he was going to sleep, and then slipped away.

In his thoughts, these two people who even have daughters can think of what they will do next with their foot nails.

"You're on good terms with him?" Artoria was a little surprised, and the two of them seemed to have a lot of favorability in the amount of time they had seen.

"I'm not a devil. "He was a good boy who had to go to work to support his family every day after school, only to be hit by a big truck driven by the driver on the way home." ”

Artoria suddenly looked at him with a very strange look, and he looked a little strange.

"Why are you looking at me like that?" said Charles, a little apprehensive.

Artoria pondered and asked, "You say, if you build a big truck, can you crash you into another world?"

Charles gave her a blank look.

The shacks in the camp were built casually, and there were not enough of them, Mira, Diana, and the little nun Jonakin, all three of them had to live together, and Matsui Shimoishi also lived with the airborne troops, and now only an empty shack remained.

Standing in front of the door of the shack, Artoria looked at Charles and sighed, "I could still see the top of your head when I slept with you last time, and now that you have grown up, you are much taller than me." ”

Charles's face twitched, he originally wanted to deal with it by the campfire for a night, but then he remembered that when they slept together, Tianling Gai was gnawed, so he became angry and said, "Yes, time flies so fast." It's not early, it's time to rest, and I'll be busy from tomorrow morning. ”

Artoria sneered, who was afraid of whom, so she followed.

Nothing was said all night.

The two men slept with blankets on each side of the shack, but one was afraid of retaliation from the other side, and the other was afraid that the other side would be hungry again, so they both quietly put on their helmets.

The last two not only didn't sleep well, but they both fell into a stiff neck.

"Are you both children?" said Diana, helpless, and a feeling suddenly rose in her heart when she used to take care of her naughty brother and sister at home.

???? (?? _??)

?? (?? Д??????????)??

"Smack!"

After she finished speaking, she twisted Ru's head counterclockwise with a hard hand, allowing the misaligned cervical spine to recover.

"Are you comfortable?" she asked, "I'll twist it twice if it's not comfortable." ”

?? (?? _??)

??????????????????????

"Smack"

Then the same treatment was given to the Dull Hair King.

The offal of the big wild boar last night was treated separately, and Charles washed and cut them into pieces, put them in a pot, and marinated them overnight with wild ginger and bad wine. Then instruct the night watchman to pour in the prepared water at dawn the next day, boil it and remove the foam in time, and when everyone gets up, a pot of pork offal soup will be ready.

While eating pork offal soup and black bread, everyone listened to Jonakin, the little nun of the Temple of Flames, explain today's plan of action.

Jonakin, who was assigning tasks for everyone, looked very excited, her little face was flushed, and her fiery red hair looked like a red apple.

Today is a south wind, the wind is not small, it is a good weather to set fire to the mountain.

At this time, they asked the people in the village that there was not much rain during this time, so there was no need to worry about rain.

When the time comes, Jonakin will set fire to the upwind area to the south, and several ignition points will quickly connect into a line of fire and then gradually spread north.

Charles and the priest of the Temple of Wisdom set fires on the east and west sides, allowing the line of fire to surround the sludge monster's area from both wings.

Meyer and his paratroopers are blocking the northernmost edge to deal with the mud monsters that have escaped and to prevent the fire from spreading.

Finally, there is Diana, who will carry the camera to film this scene and put it at the end of this epidemic prevention science and education film.

The action begins, with Jonakin standing in a small boat that floats down the river under the control of a paladin of the Temple of Light.

After crossing the barrier that Artoria had opened, the little nun held a scepter taller than herself, chanting prayers in an accent, and a moment later the flame power converged on the top of the deep staff, like a huge torch.

Every two hundred meters, a ball of magical fireballs with a diameter of one meter flew towards the woods on the north bank of the small river, exploding on the canopy of a giant umbrella, and fireballs the size of apples were scattered among the trees.

The initial spread rate of wildfires in the wild, R, can be calculated, and the formula can be obtained by ignoring the word count of a paper

R=R?? K???? K?? /cosφ

where:

R?? — The speed at which fire spreads when there is no wind

K???? – Wind speed correction factor

K?? - Correction factor for the configuration pattern of combustibles

cosφ—Correction factor for the average slope of the ground

The calculated initial spread rate of the wildfire is about 5 centimeters per second.

In less than a minute, the fire spread everywhere, and the surrounding air was heated and buoyant to spread upward, causing the surrounding wind speed to increase more and more.

The speed of fire propagation when there is no wind R?? It is inversely proportional to the water content of combustibles.

According to the formula, the spread rate of the wildfire increased rapidly under the influence of two factors: the increase in wind speed and the drying of nearby plants by the nearby flame before burning.

Gradually, columns of smoke formed a wall at the speed of an ordinary person's walk.

The wind grew stronger, and the flaming leaves were blown off, igniting the bushes and fallen leaves on the ground, and the bushes burst into flames for a moment, igniting the green leaves and green fruits above.

At this point, the formula no longer works, and the spread of the flame depends on how far the wind blows the burning leaves.

The wildfire trotted all the way north, slowly accelerating, and the insects, birds, and mud monsters in the forest fled, but there was nowhere to run.

The scorching flames burned everything, purifying everything, whether it was the mud monsters that fled from place to place, or the bacteria they sprinkled in the forest, all of them turned to ashes in the flames.

Even the mountain stream could not stop the flames, and the air was so hot that the gurgling water evaporated in a few breaths, and the mud at the bottom of the water gradually dried and cracked.

On the other side of the river in the north, Meyer and the others broke out in a cold sweat, and the smoke that reached the sky had turned into a gray wave and rushed towards them.

Although the wall of fire was still far away from them, they could still feel the incomparable power and unstoppable footsteps of this flame.

The fire burned until late at night, and the night turned orange as a result.

Countless demonic beasts in the northern mountains fled after smelling the smell of fireworks, they didn't know what the isolation zone was, only the memory engraved in their bones was high-speed, and they ran as far as they could smell this smell.
