Everything is ready only to the east wind, and on the day of the pull-out, it seems that everything is ready, but the question of the direction of the wind is still bothering Long Qiupeng. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

During the time of the Dragon Clan, the wind would blow from the lake to the land during the day, but at night it would change direction.

However, the Long tribe is located on the east side of the entire lake, and the Lu tribe is located on the north side of the lake, so Long Qiupeng didn't care too much about this problem, in his modern hometown, the wind direction changes every day, and where the wind blows is a completely probability event.

It wasn't until he and the deer went to the lake to wait for supplies that they realized that although they were now on the north shore of the lake, the wind was still blowing from the lake to the land at noon. He suddenly realized that the problem was not as simple as he had imagined.

So in the evening, he came to the lake with the deer and the great lake.

"Hey...... Sure enough...... "Long Qiupeng waited until it was completely dark, and found that the wind was blowing from the land to the lake, and as the night became thicker and thicker, the wind became stronger and stronger. He sighed heavily, looked at the deer and the lake, and said, "The idea of the wind, which blows from the lake to the land during the day and from the land to the lake at night, does not seem to be easy to come true. ”

Deer and Dahu looked at him in surprise and asked, "How do you know?" ”

Long Qiupeng looked at the deer and the big lake, hesitated for a moment, and told them: "Because during the day, the dragon god wants to come out of the water and patrol around, and at night after dark, he has to return to the water from the land to rest, so he drives the wind to blow. ”

After saying that, he turned around and prepared to return to the camp at the old site of the Tao Ministry, rest and plan the next step. But the deer and the big lake seemed to have heard something great, and looked at the lake in front of them in surprise, and couldn't help but kneel down and kowtow twice before they stood up again and caught up with Long Qiupeng.

However, of course, the truth of the matter is not as mysterious as Long Qiupeng said, because his hometown belongs to the inland plain, so he ignored it before, relying on a large area of water, because the water body and the land are heated unevenly, so the air pressure changes are also different. Therefore, the wind blows from the water to the land during the day to form the lake breeze, and the night wind blows from the land to the water to form the land breeze, which is collectively called the lake land breeze.

Of course, this wind has little effect on archery, and these archers selected by the deer can be regarded as having both strength and speed, and the incendiary arrows are heavy and inertia, so they will not be affected by this wind.

But the fire is a different story, the fire is very light and easily affected by the wind, and if the wind blows from the land to the lake, then the fire will also burn in the direction of the lake, so obviously the impact on the tribe will be much smaller.

The shore of the lake is not too far from the old site of the Tao family, but walking back, Long Qiupeng felt that it had taken about an hour. Many of the warriors had already finished their meals and gone to sleep. But he didn't feel sleepy, sat down on the campfire, and unfolded the map again.

Unless it is a windy day, the plan for a sneak attack at night will be completely shattered. However, expecting a strong south wind to blow in the north on autumn evenings is similar to planning to buy a lottery ticket and winning the jackpot.

"We're going to fight during the day!" Long Qiupeng was silent for a long time, looking at the deer who had been accompanying him.

Lu opened his eyes wide, and asked in disbelief: "It seems a little difficult to let go of arrows under the other party's eyelids during the day, not to mention that the other party has a lookout." ”

"Then let's have a front and back attack!" After speaking, Long Qiupeng adjusted his tactics.

During the day the next day, Long Qiupeng only left a few people who defended and guarded, and the rest of the people rested. Just waiting for the sky to get dark, Long Qiupeng and Lu took the first batch of people to the Lu tribe.

The Lu tribe is near the lake on one side, and the grassland on the other side, near the Lu tribe, due to human activities and primary grazing, the grass has become relatively scarce, and the grass is not high, but further away, it is half a person high, and it is relatively easy to want Tibetans.

At this time, the weather is getting cooler, and the grass is starting to turn yellow and wither, and although it is not as easy to burn as in late autumn, it is not impossible to start a fire.

At such a distance, it is impossible to burn the Furnace tribe in one fell swoop, but through this, it is still very simple to find some trouble for them.

Long Qiupeng took the deer and the others to choose a location first and dig out a separation zone. Because of the land breeze, the fire at night is easier to predict and relatively easy to control.

When the moon was in the sky and the land breeze was getting stronger, he felt that the width and length of the barrier was enough, so he began to light the fire. The flint of the pottery department was obviously much simpler than drilling wood to make fire, and it soon ignited a grass.

Driven by the land breeze, the grass slowly began to burn, and gradually ignited the nearby grass. Long Qiupeng didn't dare to stay too long, and hurriedly led his people to the ambush point, where the isolation zone was cleared early in the morning, regardless of whether the fire was out of control or not, it could be relatively safe.

In order to be on the safe side, Long Qiupeng let Lu and Dahu continue to evacuate, and made a few more burning points himself. Soon, the grass turned into a piece of grass, and a horizontal line was burned out with a brush.

Driven by the land breeze, this line of fire burned bigger and bigger, rushing towards the Furnace tribe.

Long Qiupeng and the deer hid at an observation point in the distance, waiting for the sound. But at first, the entire Furnace tribe was quiet and silent, without any sound.

Waiting was torturous, and Long Qiupeng knew that with the grass around the Furnace Clan, even if the fire burned to the bottom of their walls, it would not cause any substantial damage to the Furnace Clan, because the walls of those wooden stakes were not as easy to ignite as thatch.

If they had such determination, or because their hearts were broad, they didn't find out that the grassland was on fire at all, then Long Qiupeng tossed in the middle of the night, it would be meaningless.

Fortunately, the animal nature of primitive people made them as afraid of fire as wild animals, so when the primitive man on the watchtower finally discovered that sea of fire, he issued a warning.

Randomly, the entire Furnace Clan began to light up, and even from such a distant observation point, you could hear the exclamations from the Furnace Clan.

There are many ways to extinguish fires in the grassland, but these knowledge reserves belong to Long Qiupeng, but they do not belong to Yan Yan and his Lu tribe, so soon, Long Qiupeng saw that there were torches moving from the lake to the fire, and he knew that this was the fire fighting team of the Lu tribe that began to act.

The land breeze is not strong, so the fire does not spread quickly, but the grass is very high, so the fire is quite fierce. At this time, using clay pots to fill water does not play an effective role in extinguishing fires at all, and even as soon as the water is splashed out, it becomes water vapor. Therefore, although there were torches moving in the direction of the fire, it was clear that the movement of the fire was still moving according to the originally expected trajectory.

Long Qiupeng looked at everyone for a while, and found that the situation had been decided, so he left one after another, went to the river to find a clean and stable place to rest, and waited for the dawn after Dahu came to meet with the team.

In the bustling breeze, Long Qiupeng was gently awakened by the deer, he originally thought that he would not be able to sleep because of nervousness or anxiety, but in fact, he was slowly adapting to this high-pressure life. This night, he slept very lightly, but very solidly. When the changing of the guard was lying down just now, the sky had just been polished, and the wind direction was still the land breeze. By the time the deer barked, it was already midday, and the wind had turned into a lake breeze as the temperature rose.

"How?" The first thing he said when he opened his mouth was to ask Lu, the situation of the Furnace tribe.

The deer didn't know what he was thinking about, his expression looked a little depressed, and when he saw the deer like this, his heart also jumped. He glanced at the deer and urged the deer to hurry up.

Feeling that he had not fulfilled Long Qiupeng's request, Lu said in frustration: "The fire is about to be extinguished, but the Furnace tribe doesn't seem to have too many casualties......

Long Qiupeng was startled by the appearance of the deer just now, and when he heard what the deer said, he knew that the other party would be wrong, he laughed heartily and asked, "It's okay, when did this happen?" ”

Lu saw that Long Qiupeng didn't seem to care, and then he got up and said, "The person who just came back to change, do you need a specific situation?" ”

Long Qiupeng shook his head, because he saw that the boats on the big lake in the distance were preparing to dock, at least it sounded like they were still in a hurry until the morning, and the rest, it was better to go to the Lu Clan tribe and make plans.

The boat stopped in Dahu, and Long Qiupeng got into the shed of the boat, ready to change his clothes. Although he didn't plan to show up, it was better to be cautious. He ordered the great lake to be pierced, and not only was he to hide in it, but also a large number of burning arrows, deer, and an archer were to hide in it.

The food, on the other hand, is placed on a raft tied to the back.

These "foods" are also carefully prepared by Long Qiu Pengmingxi, and those animals look no different from ordinary animals on the outside, but there is a large mixture of pine resin oil and charcoal hidden in their stomachs. Once it burns, it's a big incendiary bomb.

In addition to this boat, the remaining three boats are all following behind, and those three boats are also the archers and burning arrows of the Dragon Clan.

When we arrived at the Lu tribe, it was not particularly early, but the workers who usually built nets by the lake were nowhere to be found. There were a lot of broken clay pots scattered on the docks, and the wet docks were full of standing water.

The team that originally guarded the docks is now only one person left.

"What about the people?" Dahu stood at the bow of the boat and asked knowingly, while Long Qiupeng hid in the shed of the boat and watched the changes.

The guard was probably too tired, and was startled by the shout of the Great Lake, and he cursed loudly. Then he said, "Put out the fire in the back!" ”

Dahu routinely talked to the man for a few words, and the deer told Long Qiupeng that if it was normal times, someone would come to help carry the food at this time, firstly to show their strength, and secondly, to supervise their work, but today, it seems that there is none.

Sure enough, the man said to Dahu: "No one! Send your things to the granary yourselves! ”
