C3550 Five-thousand-Li Flaming Beacon Smoke (1/2)
The ancient beacon communication was not slow. It was completely dependent on the visual system. In other words, it was transmitted at the speed of light.
As soon as the smoke from the beacon rose, people could faintly see the black smoke from dozens of miles away. It would be even simpler if it was night time, and the flickering of the fire was even more obvious.
Light speed was the fastest speed, but the Fire Beacon system clearly couldn't achieve this efficiency. This was because it took more manpower to do so. After all, it took manpower to ignite the beacon after discovering it.
If he was prepared, it would be fine. But if he wasted some time moving the firewood, it would be hard to say!
However, in the 21st century, there were documentaries that performed such experiments. The speed at which a beacon and an off-road vehicle transmitted information was at least three times faster than an off-road vehicle.
Even at a speed of 100 mph, the speed at which information was transmitted from the beacon had reached 300 kilometers per hour.
This was the speed of the high-speed rail!
The beacon fire spread from Jiayuguan to Zhang Ye, and then to the southeast, to Shan Dan, Yongchang, Wu Wei … At the end of the Gu Lang River, the Great Wall began to split in two.
Some headed east to Ningxia, while some headed south to Lanzhou!
From the Jiayuguan to the Gu Lang River, only two and a half hours had passed, and then the beacons were split into two and continued south. The road south took another forty minutes to ignite the beacons in the northern part of Lanzhou City.
When the beacons were lit up, the sky in the east had just begun to brighten. The citizens of Xizang City who had woken up early in the morning were all staring dumbly at the fire lit on the hills to the north, asking questions one after another.
”What's wrong?” ”Why is it burning now …”
”That's right, Mountain Flame?”
”That's not right. If it was fire, why would there be so much smoke?”
No one knew what happened when the citizens crowded onto the street. In the last two hundred years, no one had used a beacon to signal the presence of smoke in Great Qing Dynasty. They had long forgotten about the good stuff left behind by the Old Ancestor.
However, the yamen runners knew who was in charge of this affair. Upon seeing this, the Grand Master immediately jumped up. ”F * ck!” A beacon warning? Isn't that the tower on the Great Wall? ”
”Marshal Zuo must have sent a message!” ”Quickly report to Lanzhou City …”
Xigu County's Yamen Express galloped towards Lanzhou City. It was not the main logistics department where the army gathered their supplies.
Lanzhou City was shaken. Everyone knew that an incredible event had occurred in the west. However, although the fire and the smoke were fast, they were also very annoying because they could not deliver complicated news.
People knew what had happened, but they just didn't know what had happened!
The entire city had to worry for three days before they could receive a carrier pigeon from the Jiayuguan. When the officers who were left behind saw the military situation, they immediately jumped three feet into the air in excitement.
”Victory!” Stellar Gorge is victorious! The western troops have already taken over the Stellar Gorge, they have hit the Hami! ”
”Hahaha …” The entire city informed him that it was going red! Put a carrier pigeon in Xi'an City... Have Xi'an City quickly send a telegram to the whole world! ”
The streets and alleys of Lanzhou were plastered with happy red newspapers. The news of the Stellar Gorge's great victory had caused the whole Gansu Province to be in an uproar as if it was the new year!
However, at this time, Xi'an and the capital were still in a daze. They had no idea what was happening in the distant Northwest.
The Great Wall was divided into two on Gu Lang River's side. The main body continued to follow the ancient path of the Great Wall to the east. He followed the Yellow River to the Ningxia Central Guard, and then headed all the way north to Ning Shuo.
Across the Yellow River into the Red Mountain Castle, straight to Dingyuan, Jingyuan, Shaanxi... Straight northeast into Yulin City!
To Shaanxi Province, the Great Wall was the entire northern boundary line. North of the Great Wall was the Inner Mongolia, and south of the Great Wall was the Shaanxi Province. This place was the same as Shanxi, it was also the front line for the Ming Dynasty to fight against Mongolia.
