After eating a whole wild boar, Artoria's combat effectiveness was very terrifying. Before dawn, she drove a fireproof isolation belt that was two, three kilometers long and ten meters wide.

When she came back, she found that except for the night watchmen in the camp, Charles and Matsui Shimoi were happily talking about the customs and customs on the mainland.

When Matsui Shimoi saw Charles greeting the back Daemao King, he said consciously that he was going to bed and then slipped away.

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

"You have developed a good relationship with him?" Artoria was a little surprised that the two men seemed to have increased a lot of favorability during this time.

"I'm not a devil," said Charles. "He is a good kid. He has to work to support his family every day after school. But on the way home, he was hit by a truck driven by a tired driver."

Artoria suddenly looked at him with a very strange look, which made him a little strange.

"Why do you think of me like this?" Charles was a little nervous.

Artori asked, "You said, if you built a large truck, can you knock you into another world?"

Charles gave her a blank look.

The sheds in the camp were set up casually, and there were not enough numbers. Mira, Diana and the young nun Jonakin had to live together, and Matsui Shimoshi was also home to the airborne soldiers, but now there was only an empty shed.

Standing in front of the shack door, Artoria looked at Charles and sighed: "I could see your head when I slept with you last time. Now you are older and much taller than me."

Charles thrust his face. He originally thought of dealing with the bonfire all night. At this time, he remembered that when he was sleeping together, he ate the quilt and became jealous and said, "Yes, time passes so fast. It's getting late, it's time to rest, and I'll be busy tomorrow morning."

Artoria sneered, "Who is afraid of whom, so she followed in."

No words all night.

The two of them laid blankets on both sides of the shack and fell asleep. As a result, one was afraid that the other would take revenge, and the other was afraid that the other would be hungry again, so they all quietly put on their helmets.

In the end, not only did these two people not sleep well, but also had a stiff sleep.

"Are you two children?" Diana was helpless, and suddenly felt like she was taking care of her younger brother and sister who had caused trouble at home.

??(?_?)

?(?Д?????)?

"Bang!"

After she finished speaking, she tried her best to twist her head counterclockwise, causing the dislocated cervical spine to recover.

"Are you comfortable?" she asked, "I'll twist it twice more if I feel uncomfortable."

?(?_?)

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

"Bang"

Then the same treatment was given to King Daimao.

The big wild boar's pig miscellaneous food was treated separately last night. Charles washed them and cut them into pieces, put them in a pot, marinated them with wild ginger and poor wine for a night. He also told the night watchmen to pour in the water that had been prepared at dawn the next day, and then boiled them and took away the foam inside in time. When everyone got up, the pot of pig miscellaneous food was ready.

While eating pig soup and black bread, everyone listened to Jonakin, the young nun of the Temple of Fire, explaining today's action plan.

Jonakin, who is assigning tasks for everyone, looks very excited, with a red face? Plus her fiery red hair? She looks like a red apple.

What is blowing today is the south wind, and the wind is not small? It is a good weather to set fire to the mountains.

At this time, they asked the people in the village?      There was not much rain during this period, so don’t worry about it.

When the action is coming, Jonakin will set fire in the windy area in the south. Several fire points will quickly connect to the line of fire? Then gradually spread to the north.

Charles and the priests of the Temple of Wisdom set fires on the east and west sides respectively? Let the line of fire surround the mud monster's activity area from both wings.

Meyer led the airborne troops to block the northmost point, dealing with the silt monster that escaped by chance and preventing the fire from spreading.

Finally, it was Diana, who would carry the camera to take a picture of this scene?      The end of this epidemic prevention science and education film.

The action begins? Jonakin stood on a small boat, which floated down the river under the control of a paladin of the Temple of Light.

After passing the isolation belt opened by Artoria, the young nun held a magical staff that was taller than herself, sang prayers with an accent. After a moment, the divine power of flame gathered at the top of the deep staff? It looked like a huge torch.

Every two hundred meters, a ball of magic fireball with a diameter of one meter flew towards the woods on the north bank of the river? It exploded on the canopy of giant umbrellas, and fireballs as big as apples were scattered in the forest.

Can the initial spread rate r of wildfires be calculated? After ignoring the number of words in a paper, you can get the formula

r=r?k??k?/cosφ

Where:

r?—The spread rate of fire when there is no wind

k??—Wind speed correction coefficient

k?—Correct coefficient of combustible material configuration pattern

cosφ—Ground average slope correction coefficient

The initial spread speed of wildfire that can be obtained after calculation is about five centimeters in seconds.

In less than a minute, fire points spread everywhere? The surrounding air spreads upwards under buoyancy after being heated? The surrounding wind speed is getting stronger and stronger.

The spreading speed r of fire in the absence of wind is inversely proportional to the moisture content of combustible substances.

From the formula, we can see that the spreading speed of wildfires increases rapidly under the influence of two factors: the increase in wind speed and the nearby plants being dried by the flames next to them before burning.

Gradually, cigarette columns formed a wall at the speed of ordinary people walking.

The wind became stronger and stronger, and the burning leaves were blown off, igniting the shrubs and fallen leaves on the ground. The bushes rose for a moment, igniting the green leaves and green fruits above.

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

The wildfire trotted northward, slowly accelerating, and the insects, birds and mud monsters in the forest fled in panic, but there was nowhere to escape.

The scorching flames burned everything and purified everything. Whether it was the mud monsters running around or the bacteria they sprinkled in the forest, they all turned into ashes in the flames.

Even if the streams in the mountains cannot stop the flames, the hot air makes the gurgling water evaporate between a few breaths, and the silt at the bottom of the water gradually dry and cracks.

Meyer and others on the mountain across the river to the north were sweating coldly. The thick smoke that reached the sky had turned into a huge gray wave and rushed towards them.

Although the firewall is still far away from them, you can still feel the unrivaled power and irresistible footsteps of this flame.

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