It is not easy to set fire to the mountain, and it can be less to light a fire casually, but the fire is slow, and it takes a lot of time to form a prairie fire, and the entire forest is burned, which is not efficient; If you collect a large amount of dry firewood and place it in the upwind position, and at the same time light more than a dozen places, the fire borrows the wind momentum, and the wind helps the fire, it is easy to make the fire monstrous and unstoppable, so it is very important to prepare in advance.

Li Rui estimated that the enemy used this trick to attack, it was definitely not a small fight and intimidation, intending to scare everyone away, but really doing so, he was a little anxious, and looked at the direction of the camp, the scientists learned that the enemy had set fire to the mountain, they all panicked, and accelerated the speed of repairing the fortifications, while the brothers cut down trees in the northwest direction.

Of course, you don't need a knife to cut down a tree, but directly use a gun, and the laser is like an indestructible cutting machine, which can easily bring down a big tree, and everyone collects the cut branches and tails, puts them in front of the fortifications, and then covers the excavated soil, piles them into a pile, and then places the tall trees horizontally on the fortification mound.

Half an hour later, everyone put down more than a dozen big trees, the trunks of which were all piled up together, two meters high, three meters wide, and more than ten meters long.

There are many people with great strength, more and more big trees are put down, become the material of the fortifications, and another section of more than ten meters long, two meters high, more than three meters wide fortifications are piled up, the trees are thick, the wood is solid, the laser gun is not easy to penetrate, and it is relatively safer for people to hide behind such fortifications.

In order to be on the safe side, and the enemy has not yet attacked, everyone continued to cut down trees to strengthen the fortifications, and built another one behind the two fortifications.

In this way, the three fortifications are distributed in an inverted triangle formation, with these three fortifications, everyone is confident that they can block the enemy's attack, and the scientists will spread the excavated soil all over the surroundings to avoid the spread of the fire, which reminds Liu Wu that everyone saw that the fortifications were almost built, and did not rest, but continued to cut down trees, expanding the vacuum belt to a farther place, and spreading it with fire prevention.

After two hours, everyone was tired, but their hearts were a little settled, with these preparations, what could the enemy do even if they set fire to the mountain? Liu Wu gave an order, and the brothers seized the time to rest and recover their strength in preparation for the upcoming big battle, while burning the fire and roasting meat.

The enemy has a portable radar, everyone's whereabouts have nowhere to hide, there is no need to hide, it is better to burn the fire and eat generously, what to do, the time passed unconsciously for another half an hour, the sniper was full of food and drink, climbed a big tree as a secret sentry, replaced Li Rui, Li Rui came to the camp after getting off the tree, looked at the rough fortifications made of wood, the trench dug was not very deep, and there was stagnant water in it, and couldn't help but smile.

"This fortification can be used alive." Liu Wu saw Li Rui's thoughts and said with a smile.

"It's okay, the most important thing is to have water, and wet the towel for a while to prevent poison smoke." Li Rui said with a smile.

Once the fire burns, the smoke is billowing out, rotten leaves, animal carcasses, poisonous mushrooms, etc., will definitely be burned, these things are poisonous, it is definitely not possible to inhale them directly into the body, it is safer to cover your mouth and nose with a towel, everyone understands people, and smiles knowingly.

Li Rui stepped forward, casually found a piece of wood and sat down, took the barbecue meat handed over by Liu Wu and ate it, while chatting with everyone first, suddenly, the sniper who was observing the enemy situation on the tall canopy shouted through the walkie-talkie: "Captain, the enemy has begun to set fire to the mountain, at least more than 20 places have been lit, and thick smoke has come out." ”

Because they guessed that the enemy would set fire, everyone didn't panic, smiled faintly, and didn't care, Liu Wu said excitedly: "Brother, the enemy's move was once again expected by you, very good, the enemy is finally going to attack, presumably they will attack after waiting for the burn to be almost burned?" ”

"It should be, this fire is not small, the enemy will not attack in a hurry, it must wait for a while, otherwise they can't stand the temperature." Li Rui said with a smile, looking at everyone, one by one they were still wearing the captured black robes, this black robe was peeled off from the corpse when attacking the underground base, at that time, in order to infiltrate into the valley, and then there were many battles and rushes, no one bothered to throw it away, Li Rui smiled: "While the fire has not yet come, let's wet the black robe for backup, it is best to wet the clothes on the body, but I didn't expect that there was water seeping up in the trench dug out, just right."

"yes, God is helping us." Liu Wu smiled, gestured to everyone, everyone took action, walked to the edge of the trench, took off the black robe and got wet, some people were troublesome, jumped down directly, rolled in the water a few times, and got up again when the whole body was soaked.

Scientists also reacted, have to follow suit, the surrounding air is cold and damp, there are streams gurgling in many places, resulting in many places under the hollow into potholes, the depth of the shallow is different, the dug trench underground seepage is normal, and the amount of water is not small, is continuing to go up, most of the trenches are inside.

Li Rui was completely relieved when he saw the water, not to mention that the fire in the vacuum area could not be cleared, even if it didn't, even if the monstrous fire burned around everyone, it didn't matter, just need to get into the water, at this time, a soldier proposed: "Captain, I have experienced a fire, and I know that once the fire rises, the temperature is very terrifying, and no one can be roasted to death, maybe the water in the trench can be evaporated, and it is best to take some defensive measures." ”

"What do you think?" Liu Wu asked suspiciously, there is still some time, I can prepare as much as possible to ensure that everyone's lives are naturally good.

"Don't we have a lot of shorter wood here? As long as it is a little longer than the width of the trench, and it is placed across the trench, and some branches and hay are spread on it, and then the excavated earth is spread and made into a cover or something, and the people hide underneath, and the trench becomes a simple bomb shelter, and the people inside will be much safer when the fire passes over the trench. The fighter hastened to explain.

Everyone's eyes lit up, and they all looked at Liu Wu, Liu Wu estimated the time, and immediately said: "Quick, take action, the three trenches will make one of these simple fortifications to prevent fire, and the fire may come over ten minutes later." ”

"Yes." Everyone responded in a deep voice and took action.

At the moment of life and death, if you can prepare a little more, the chance of survival will be greater, no one wants to be lazy, even the scientists are in a hurry to act, Liu Wu pulled the demoman and said in a deep voice: "You go to the front of the enemy on the way to lay mines, and use all the anti-infantry mines you raised." ”

When evacuating from the valley to the mountains and dense forests, the Demoman cleared a lot of anti-infantry mines along the way and handed them to the scientists to take as backups, which was just right for use at this time, and the Demoman agreed knowingly, called Li Rui for help, and the two hurriedly prepared to go.
