"Dr. Wu, you are with the observation post."

    After arriving at the fire, Captain Li explained.

    "Yes," replied Wu Mian crisply.

    "Do you know the precautions?"

    "Observe the mountain fire. If there is a possibility of resurgence, I''ll choose an escape route immediately. It''s best not to go up the mountain or into the valley." Wu Mian said.

    Captain Li nodded and turned to pick up the wind fire extinguisher from Bai Dalin''s hand.

    "Let me be an observation post again!" Bai Dalin said angrily.

    "Bad?" Wu Mian asked with some confusion.

    "Of course not. They just put out the fire with their heads down. My eyes are good. I''m very nervous when I stand high." Bai Dalin said. "Once, we were close to the fire and were taking a final rest. A spark fell on the tree behind the captain. I went up and kicked it."

    "It''s really dangerous."

    "That''s the pine oil thing. If you want to bang, the tree will become a torch, and then the back road will be broken. You can''t run out if you want to run."

    The fire spread quite rapidly, which Wu Mian knew. If the grassland is better, the spreading speed of surface fire is 8kmh and that of canopy fire is 25kmh. The speed of running a marathon on the flat ground is basically the speed of the spread of crown fire.

    But on the mountain, people can''t run too far.

    "So the captain asked me to be an observer from then on." Bai Dalin was a little depressed and looked at the position that had not been thoroughly handled with a wind fire extinguisher and broom.

    In particular, some tree roots look like burned dead trees, but the temperature is very high, and they may rekindle again anytime, anywhere.

    In recent years, the mountain has been closed for afforestation, and there is no one in the old mountain forest all the year round. I don''t know how thick and deep the broken branches and leaves are buried. There are ashes on the surface, but no one knows what it is below.

    Captain Li took people to deal with the embers. There was a fire from time to time, and they were all dealt with one by one.

    They are also quite experienced in handling and cooperate with each other. It can be seen that this group is not the first day to put out the fire together.

    Bai Dalin stood at a high place, constantly and slowly changed direction, tried not to miss any points, and monitored all risk positions around.

    Helicopters and medium-sized planes flew in the sky, sprinkling tons of water on the burning red mountains in the distance.

    The fire has been controlled, and Wu Mian is not very nervous. In this kind of non-human fire fighting, there is little possibility of casualties.

    If we can have the B52 ammunition to hold water, or fill the rocket with water... Wu Mian''s thoughts are out of tune. If only this could happen. With the artillery strength of the people''s Liberation Army and several rounds of saturated shelling, no matter how big the mountain fire can be extinguished.

    Wu Mian also knows that it is fantasy.

    The tropical rain forest is easier to say. It has high humidity and there are few mountain fires. Countries with the same dimension will develop or introduce fire-fighting aircraft as long as their national strength allows.

    In the past, the best use should be that the Canadian government developed an amphibious aircraft - cl-215415 for forest fire prevention.

    Cl415 is nicknamed "super ladle", which is known as "the most effective tool to deal with forest fire".

    It has a four chamber and four door water tank system, which can hold 6137 liters of water foam mixture. When passing any water surface at low altitude, it can quickly fill the water tank.

    If the distance from the water source to the fire site is 11km, it can complete 9 times in an hour and put more than 55 tons of water into the fire site.

    But now the most powerful aircraft is the domestic kunlong-ag600.

    The roar came from the sky and never stopped. The old shuihong 5 and a new kunlong-ag600 kept flying to the fire and throwing tons of water.

    If kunlong-ag600 had become an organic train, it might have been all right. Wu Mian thought in his heart.

    "The big guy was just delivered. He said that he was still in the experimental stage and his performance was unstable." Bai Dalin pointed to kunlong-ag600 in the sky. He said that his eyes were still maintaining a uniform speed, his vision was scattered, and he monitored the surrounding plants and trees.

    "Well, it seems that it hasn''t been studied for a few years. We still need a lot of actual combat, modify the data and gradually improve it." Wu Mian nodded.

    "Yes, it''s just the actual combat data." Bai Dalin said, "our captain said that this big guy can get 12 tons of water in 20 seconds. It''s just that he flies too slowly, which is similar to the old water boom 5. If there are 10 or 20, I think we can retire all grassland and forest fire prevention."

    "Just take your time," said Wu Mian. "The water boom 5 has been used for 30 years. Isn''t it that the country''s national strength has just gone up and is developing a large aircraft."

    Wu Mian squints at the kunlong-ag600 flying in the sky, which is about the size of Boeing 737. He says that the speed is a little slow, but there is always a speed of 500km per hour.

    Kunlong-ag600 is even stronger than Boeing 737. The 737 has only two engines. Wu Mian sees that, as introduced in the data, kunlong-ag600 has four engines.

    The roar was like rolling thunder, and rushed to the fire site with more than ten tons of water.

    Technology is the primary productive force. Wu Mian knew this long ago when he underwent surgery. But now when I see the kunlong-ag600 with accumulated practical experience, I feel more shocked.

    Its swirling figure in the sky, with a trace of strength called SA Shuang. In particular, seeing more than a dozen tons of water being put into the place where the mountain fire is booming, the color of the fiery red mountain is darker. Wu Mian has more expectations in his heart.

    "Once when we put out a fire, a water boom 5 was wrong and regarded the fire we burned in the isolation zone as a live fire and directly dropped a few tons of water from the sky. That felt great!" Bai Dalin said with a smile, "just like the typhoon and rainstorm, I can''t carry my board and eat shit directly."

    "It''s all wet."

    "Drenched? Let''s say, once I take off my shoes, half a kilo of water is in my shoes." Bai Dalin said with a smile, "I really hope we are the last batch of grassland and forest firefighters. In the future, there will be more than 20, 200 sorties, and thousands of tons of water can''t carry any fire."

    "Fast, fast." Wu Mian whispered.

    "Captain! Captain! There is a residual fire of tree roots at 30 °, 220 meters behind you right." Bai Dalin suddenly pressed the intercom and reported the residual fire to captain Li.

    This guy looked at five big and three thick. In fact, he was very careful. Wu Mian thought of it in his heart.

    After Bai Dalin''s report, Captain Li didn''t move. A soldier rushed over and put out the residual fire.

    After beating the residual fire was a physical strength, it was just a tree root. The residual fire was completely destroyed, and at least hundreds of brooms were swung.

    Climbing the mountain for ten hours, coming here without sleep and continuing to work is a great test of physical strength and spirit.

    Gradually, Bai Dalin''s nagging voice decreased, and he kept reporting new situations. This area is closest to the fire. Although the fire has been extinguished, embers continue to burn.

    As the sun rises, the temperature gets higher and higher, and there are more and more new fires. Finally, even Wu Mian swung a broom and took part in the fire fighting.
