On Tubao Mountain, the big dragon was transported by the concubine, and a weather vane was inserted on the highest mountain.
"What is this?"
Danzhu was entrusted by Yan Zai to make this strange gadget, and Yan Zai inserted this wood-copper composite weather vane high into the highest point of these small hills.
The arrow above is in the shape of a Guzi.
"Ah, this is just a thing to measure the wind direction, just like what I told you last time, there is nothing special about this, it just always points to the source of the wind, looking at this thing, you don't need to manually take the leaves to find the wind source"
During the Xia and Shang Dynasties, people already knew that by hanging a long strip of cloth on the head of the flagpole, they could see the direction when the wind blows. It was called "½" at that time, and this thing was the ancient version of the weathervane.
However, the cloth strips are relatively soft, and are often blown around by the wind, with uncertain directions. So the ancients changed the cloth strips into bird feathers. The middle of the bird's feathers is elastic, so it won't shake when the wind blows.
In the Han Dynasty, the famous black technology master Zhang Heng created a new version of the wind vane, which is called "Xiangfengwu". It is a crow made of copper, which is placed on the head of the pillar. Point in the direction the wind blows.
The most powerful weather vane in the ancient version is the iron phoenix on the Yuanjue Temple in Taiyuan, Shanxi in later generations.
So this thing is rare, but the principle is very simple.
? When I was working in the past, I often came into contact with this thing. It is more common in plateau pastoral areas
Šu Zai looked at another stone tablet on the top of the mountain. It was a weather watch. Since the implementation of the Taihao Clan, most tribes would make this thing. It was nothing more than a record of some important climate measurements and judging the time.
The main function of the weather meter is to help farming civilization observe the sky, avoid bad weather such as wind, rain and thunder in time, and prevent the planting and harvest of grain from being affected.
The dragon was brought here because it has the ability to pray for rain. It has brought many people today, but most of them are on the mountainside.
After observing the direction of the wind around here, Yan Zai pondered for a while, and then shouted down, telling the big guys to start digging roots.
The roots of the trees fix the soil, and if some roots are dug off, the connection between the soil will not be too close. If you cut some wood every few steps, when the heavy rain comes, this part of the mountainous area will also be more dense due to sparse vegetation and soil erosion. It is prone to flash floods and collapses.
The cause of flash floods is not complicated. Flash floods in many places in later generations are actually inseparable from the random cutting of trees. Now, there are red pine nuts and dragons, which turn heavy rain into heavy rain on heavy rainy days. That is a little problem nothing.
But Yuzai didn't intend to let his teacher go into battle from the very beginning, just as Dayi said, if none of these strong men came, what would the tribe have now?
The answer is already there.
The dragon is not strong, and the tribe can completely surrender with its own ability. It is incomparable to the old tortoise. Now, as an important labor force of the tribe, the rain-seeking ability of the dragon can come in handy in this battle.
"This is not a fight."
When Yan Zai was asked about the preparations for this battle, he responded to the clansmen who asked in this way.
"This is a disaster, and we're just trying to protect our homeland."
Whether it is the Deyou clan trying to attack Nanqiu, or the mountain torrents that are about to destroy the Deyou clan, this is indeed a disaster after another.
"Fight? The numbers are not equal, so why is it called a fight?"
After Yan Zai calculated the wind direction, under Danzhu's gaze, he pointed to the southwest direction!
"In five days, there will be heavy rain from the west, and autumn water will come in season!"
I have already found that the breath is damp before. As a qi refiner, under the guidance of Chisongzi, she is very sensitive to changes in qi. In addition, the water level of some nearby water streams has begun to rise, and the water body has gradually become turbid. There was a lot of pressure.
The sky in the southwest looks a little dark, and the wind speed is not normal.
The vitality of the birds decreased, and the insects began to appear in large numbers, but quickly disappeared.
Most notably, the nearby ants started to panic.
Huge pressure is approaching, and the heavy rain in autumn comes in accordance with the season, and after this heavy rain, the weather will gradually become colder, but in the south and Lingnan, this change is not obvious, or even absent.
Therefore, it still maintains the end-of-summer, and even the hot and dry weather at the beginning of autumn, which also leads toRainfall is still abundant.
The people of the Chifang family began to dig tree roots on the mountain, and the horn of Youhou was carried by Dayi. With the addition of the stone gall, the mountain torrent could be rushed down the route that Yuzai wanted.
"The heavy rain in the south stopped two days ago, and Di Youshi should have been unable to hold back."
Yumeng came back from the south and told Yuzai that the big monkey seemed to have called for help. There was a strange cry from the direction of Tianbi Mountain, like like a baby crying .
"There is a strange beast in the south called Gu Diao"
Red pine nuts popular science in time: "The Gu sculpture sounds like a baby, and likes to eat people the most."
"It seems that this big monkey god has really found a rescuer."
Yan Zai muttered, feeling very helpless again.
You are strong enough, okay, why are you still looking for rescuers! Can't afford it!
Do all monkeys like to ask for help? Who did you learn this from?
?When the reinforcements arrive, I will attack from both sides, surround and encircle, charge left and right, break the enemy army, and win this battle
You are thinking of peaches to eat.
Šuzai has made so many preparations here, just to prevent being taken away by the opponent. After all, the Diyou clan is very powerful. With the Chifang clan's manpower, this is not an opponent at all, okay
As for the reinforcements, they have also been invited, but all the tribes only know that Di Youshi may have taken action, but the exact time is unknown.
The main reason is that the time is too short and the distance is too long. People like Dayi can travel very fast, but others can't.
But fortunately, the reinforcements are already on the way, and the three mountains and four fields are the first to respond, expressing that they will send people over.
"The reinforcements from the Three Mountains and Four Fields came from a short cut and arrived at Shanbo's Field. They should arrive in the next three days or so."
"As for Changfeng Zhiye's reinforcements, it will be much later."
Danzhu fell into a short thought as he watched the concubine who made the plan in an orderly manner.
Although I thought that it was absurd for Yanzai to change the river course, after observing this period of time, I found that Yanzai, a little wizard, really has two brushes.
In Danzhu's view, the understanding of climate and hydrology is enough to enter the central water conservancy department.
"And one more thing."
Dan Zhu said: "My words are rather harsh Zai, although the layout here is perfect, but if the other party does not go from Shanbo's Field, but takes a long way to the side, what will you do?"
"Wars cannot be won by relying on mental disorder."
Šu Zai said: "Ah Hong, you are right, so, I am going to send a team of baits"
Danzhu nodded seriously: "Bait, yes, but you have to"
Yanzai took out a wooden sign and handed it to Danzhu.
The wooden sign reads "Akakata in front, this section is under construction and maintenance".
And engraved the head of a lamb.
Danzhu was a little confused.
And Yan Zai said, according to Shan Dushen's arrogant character, if you don't let him come, he will definitely go this way!
Moreover, Yan Zai specifically asked Danzhu to go with Yan Pan.
