During the Warring States period, the transmission of intelligence has always been the most headache for the nations.

Whether it is the Golden Arrow Transmission or the Flying Eagle Biography created by Yongcheng, because the content described is too little, it can only be described in the briefest few sentences. This is a very serious problem, the information will be passed on many times, and when it reaches the king's hands, it will not necessarily be the original information.

In this way, if the amount of information is too large, the golden arrow will not be able to shoot far, and the flying eagle will not be able to carry it, and it is very likely that it will be intercepted by enemy spies on the way, causing huge losses.

In the battle of Qin and Zhao, Ying Zheng was able to cooperate with Zhao Qian so well, and even explored Zhao Jia's every move thousands of miles away so clearly, so that Zhao Qian's pursuit was so accurate, all because of Lin Sheng. These royal families are secretive, and the two of them don't dare to use those conventional communication methods at all, but Zhao Jia is lucky that he was not killed by Zhao Qian.

In the current situation, the Qin State has to fight against several other countries, and this kind of thing may also occur. As everyone knows, not everyone can use a wide range of sound transmission techniques like Lin Sheng, and for ordinary masters, using sound transmission techniques for a long time is a loss of their own strength. It can help you spread the word in a short time, but if it goes on for a long time, no one can stand it.

Now Dawn has said, 'If you want to get rich, you must first build roads.' Many people have a question, to convey the message, why build roads? And why can you be rich? Regarding the limitations of the times, Wang Heng, Qianyi, Xingling and others did not understand.

But hearing this, Ying Zheng's eyes lit up, this sentence was too familiar. Very early, he wanted to build a passage from Xianyang to Bashu, but because of the delay of Zheng Guoqu, the road was not repaired, and the old lady Ba was furious and had doubts about the decision-making of the Qin Palace. Later, with a series of things, Ying Zheng was too busy to take care of himself, and he did not mention the road construction again.

Chenxi said: "The transmission of information, the most common is that the herald soldiers ride horses to transmit messages, and post stations are set up at various checkpoints along the line, so as to change horses and not people. This method is common, but it is practical and cheaper. Heralds can carry a large number of documents to collect information from all sides, and if the local spies can't understand it, as long as the intelligence is sent to the power center, a large number of intelligence personnel will help analyze it. ”

"It is not the enemy's interception that determines the speed of the herald, nor the horse's lack of endurance, but the road."

"As we all know, there is no perfect road from Xianyang to the rest of the world, and many places still need to cross mountains and mountains, and there is too much time to lose. On some routes, there were no post stations at all, and the heralds had to endure the difficulty of not having supplies in case the information was lost, and they did not dare to stop in the big city. ”

"So I propose to build a road from Xianyang to Zhongnan Mountain, and set up more post stations along the way, which can be reached in three hours as soon as possible, which is more reliable than any communication method."

Wang Heng asked: "It should cost a lot to build such a road, and we will follow the King of Qin and see that he can unify the Central Plains." Although road construction is important, it cannot hinder the great cause of Qin's unification, you must always tell us where the benefits of road construction are. ”

Dawn said confidently, "There are many benefits. ”

"First, it can maintain a stable transportation channel, and after the road is repaired, it can not only accurately transmit messages, but also transport money and grain. No matter how convenient water transportation is, the speed still can't catch up with the land. ”

"Second, drive the residents along the line, so that the farming is over, and the farmers who are idle at home have work to do. As long as there are people, the development of commerce is indispensable, and various wealth taxes are derived from it, which will also reduce the financial pressure. ”

"Third, if the road is widened and widened, the speed of the army will be fast. After having roads, the speed of logistics is even faster than the speed at which the enemy country attacks the grain routes. Why is it fast? Because the logistics troops can take the repaired road, while the enemy army sneaks up on the grain road, they will not dare to take it at all, and will only block the road in advance, which will lose first. ”

"Fourth, not only one road should be built, but several roads should be built, and wherever the battle goes, the road will be built. In particular, the road from Xianyang to Bashu must be repaired before all roads. After the road is repaired, no matter which country Qin starts a war against, Bashu's logistics grain and grass can arrive within three days, and it can reduce losses along the way. ”

"Fifth, after the unification of the Central Plains, the road will be built beyond the Great Wall. The battle of the Central Plains was only a civil war for the Chinese, and our real enemy was still the Huns outside the Saiwai. If the Huns attacked, when the beacon fire was ignited, the troops from all over the country would follow the avenue, abandon the burden of materials, and rush to the border pass with light equipment, which would definitely stop the Huns before they attacked the Great Wall. ”

"I calculated that if such a road is built, a fast march on the avenue, and there are post stations along the way to replenish it, the speed is definitely not slower than that of the Hun cavalry. The Huns are stronger than us, and they are only cavalry, and if they lose this reliance, what will they do to fight us? On the height of the city, on the quality of the army, and on the courage of the battle, the army of any country in the Central Plains will not lose to the Huns. ”

"Therefore, the roads must be repaired, and at least the main roads must be repaired before the reunification of the Central Plains. Such a road, with Xianyang of Qin as the central point, I call it Qin Straight Road. When encountering mountains and digging mountains, and building bridges when encountering rivers, they will build such straight roads. Do you imagine the strategic significance achieved if the garrison of Yongcheng set out from Yongcheng and passed through Xianyang, Hangu Pass, Handan, and Yanmen Pass in just two days? ”

Hearing this, Wang Heng's eyes lit up, and he said directly: "That is too significant, the soldiers of Yongcheng and Yanmen Pass are united, and they can completely attack the Hun tent, which has a decisive role." No matter how smart Mao Dun was, he couldn't have imagined that the speed of the Yongcheng soldiers would be so fast, and he would definitely be caught off guard. ”

"Two days, even if Mao Dun learns that the garrison is leaving, with the intelligence ability of the Huns, it will take three days to know. And we can join forces within two days, and we will be able to come to the city within three days, so in such a short time, what can Maudun take to fight? When a battle happens, it takes months, or even more years, to prepare, and not only does it take a surprise, but even I dare not think about it. ”

Ying Zheng also nodded when he heard it, but Zhongli said worriedly: "Qin Zhidao, if you want to repair, how can you repair it?" Gongzi has already formulated a national policy, and after the reunification of the Central Plains, he will build the Great Wall and strengthen the border city defense. The state treasury will definitely not be able to support these two huge projects, and I am afraid that even the private treasury of the countries will not be enough to put it in. ”

Wang Heng was worried, and said: "Many Great Walls have fallen into disrepair for a long time, and if they are not repaired and reinforced, the scattered Xiongnu army will easily be able to break in." In the battle with the Xiongnu, the battlefield must be placed outside the fortress, otherwise the damage to the Central Plains will be great. Although the Qin Straight Road is good, but those roads are cultivated, the Huns will know sooner or later that others will not put the main force of the Huns in those places. ”

"More importantly, how is Qin Zhidao going to be repaired? If the repair is not good, it will cause labor and loss of money, and the status of the king of Qin will not be guaranteed. After all, the main battlefield is still a war with other nations, and the pros and cons must be clearly distinguished. ”

Ying Zheng also asked: "Xi'er, the road must be repaired, how do you think it should be repaired?" ”

Chenxi smiled and said, "Since I said it, I naturally have a way to build the road." Take the road from Xianyang to Bashu as an example, you can only build one main road, branch one along the way, and pass through my Zhongnan Mountain, then you don't need to spend much money. ”

"In order to reduce expenses, the road builders chose to be idle farmers at home, and at the price of one load of grain a month, many Qin people should flock to it. Let Mrs. Ba pay for the grain and grass, this road is built for her, and she will definitely not let Xianyang trouble. In fact, Mrs. Ba resented her the most because of Zheng Guoqu, and stopped her road. ”

"In the past, in order to support the front line of the war, the grain and grass transported by Bashu, because of the dangerous roads, ten loads of grain and grass were transported to the front line, and only three loads were left. Why is this happening? It's not because there are no roads, the logistics horses go slowly, the people and horses have to eat, and the mountain roads are steep, and there are destroyed grain carts every time. As long as there is a delay for every day, less grain and grass will be transported, and when we reach the front line, we can only provide so much grain and grass. ”

"If you were the one in charge, wouldn't you be worried? I understand that I sent ten loads of grain and grass, but you told me to send only three loads, and people with a bad temper will definitely fight with you. Those grains and grasses are all bought in exchange for real money, and they have lost so much, all of them are spread on the Ba family, and everyone will have a heart to complain. ”

"Take Wang Heng as an example, this time you personally escorted the money and grain back to the Ghost Valley, I can accurately tell you that even if you send it in person, you will not be able to send it in such a complete quantity. From Xianyang to Guigu, the road is even more bumpy, and it is necessary to take both land and waterways. The chain bridge has been broken, you can only be hoisted up from the cliff, which will inevitably have the accident of falling money and grain, and the money and grain falling into the abyss, who should be counted on the head of this loss? I am very responsible to tell you that Ying Zheng was able to support the Guigu this batch of money and food, and he had already done it behind the back of several queen mothers, and he would not admit this matter to the outside world, so you can only be responsible for yourself. ”

When it was his turn, Wang Heng said bitterly: "I won't tell you, ten layers of money and grain, I can smoothly transport back to the third layer, it's already very good." That's why we want to form an alliance with King Qin, we are ready for long-term cooperation, the main root is that the last time we recruited too many disciples, the family members were all martial artists who didn't produce anything, and they consumed food all day long, and I will slowly discuss changes with King Qin in the future. Counting on the support of others is not a long-term solution. ”

At this time, Wang Heng thought about the matter at home, Qin Zhidao would definitely be repaired, and the broken chain bridge would have to be reconnected. In the battle of the sword mound back then, so many people were deceived into entering and the chain bridge was cut off, but in the end, it was his own family who was harmed.

It is inconvenient for everyone to go down the mountain, so they can only live on the mountain, it is good that the time is short, but after a long time, so many people eat and drink Lazar, and the two leaders of them are always responsible. This is really lifting a stone to shoot himself in the foot, it is easy to cut the chain bridge, but if he wants to reconnect, imagine the abyss from the sword mound to the ghost valley, and reconnect the two distant cliffs, Wang Heng feels his scalp tingle when he thinks about it.

If you don't connect, you can't do it, Yingzheng can support them a few times, that is already a great favor to Guigu, do you still expect others to support them for the rest of their lives? It's simply impossible. Gai Nie definitely doesn't understand these things, but Wang Heng understands that the future of Guigu needs to be changed.

The construction of Qin Zhidao, an idea that has not yet been perfected, has won the approval of Yingzheng. The specific method of repairing still needs to be studied slowly, and it is always necessary to consult with the ministers after returning to the palace, and everyone will arrange a series of procedures before issuing the decree.

At this time, let's first find out what happened to Lin Sheng in Xianyang.

Under Chenxi's personal order, the situation in Xianyang came from the Qin Clan's ranch one by one through the reactivated transmission line.
