Wang Jun walked into the yard, and Xiangyun followed her with a pigeon cage.

Seeing Han Qian and Xi Ying sitting in the courtyard talking, Wang Jun said happily: "The day before yesterday, Wang Zhu went to Longtan, and I specially asked him to take Ah Zi and Ah Zhu to Longtan to fly, you see, Ah Zi and Ah Zhu have just flown back, and they also brought back the letter written by Wang Ji in Longtan!" ”

Wang Jun took the pigeon cage from Xiangyun's hand and asked Han Qian and Xi Ying to look at a pair of gray-white domestic pigeons in the cage.

"Really?!" Xi Ying asked excitedly.

Long-distance rapid communication is one of the most difficult problems to solve in the world, but the development of Tangyi to this point urgently needs to establish a more complete and rigorous intelligence reconnaissance and transmission system.

Although the world has a certain understanding of bird biography, especially domestic pigeon biography, Han Qian also thought about this problem when he was in Xuzhou, but he did not have the conditions to do this.

Even if there were some children of the family who raised pigeons to enjoy the game, they were very few, and the relationship between Xuzhou and them was by no means harmonious.

In addition, using the homing properties of domestic pigeons, emergency communication can only be one-way.

That is to say, the domestic pigeon is raised in the first place, and the domestic pigeon can only be released in the field, and the domestic pigeon will bring the letter back to the first place where the nest is located.

However, in order to ensure that the pigeon's ability to find the nest is not weakened, it should not be taken out of the nest for too long.

At this time, in order to ensure that the emergency communication function of a certain location is exactly effective, it is almost necessary to feed several groups of pigeons at the same time and take them to other places in turn.

In this way, it is possible to ensure that the pigeons stay in the nest for the main time and that their stay in the field is as short as possible.

In addition, domestic pigeons fly long distances, and the requirements for breeding, breeding, feeding and disease prevention and control are extremely high.

Even if there is a certain understanding of the domestic pigeon biography, many complex technical issues are decided.

No other regime in history has been able to keep carrier pigeons on a large scale as a means of emergency communication, and for a long time, individual families have occasionally kept them as playthings.

Or after the victory in Wujinling, Wang Juntuo people found a few pairs of domestic pigeons from Huzhou, and fed them with the maids around them, and they have only hatched to the third generation.

It was still necessary to bring some of the young pigeons to the Huaiyang camp for feeding in the winter last year, and only recently began to verify the emergency communication capabilities between the carrier pigeons and the Huaiyang camp in the outside area.

At present, it seems to have some effect, but there are too many difficulties to overcome in order to establish a real emergency communication system based on this.

Fortunately, Tangyi's resources are now slightly broader, and at the same time, they are starting to establish a more complete and powerful intelligence reconnaissance and collection system, and some things are also qualified to be promoted.

Xiangyun put a pair of gray feather pigeons back into the pigeon nest, Wang Jun noticed the secret letter from Dingzhou, and after watching the film, he frowned and said in a deep voice:

"Maybe before the Liang army captured Luzhou, Wang Jingrong would persuade Wang Yuankui to take refuge with the Mughus......"

Xi Ying was taken aback, and said with some uncertainty: "Wang Jingrong is in charge of the elite soldiers in the northeast of the Jin Army, and he sits on the three most fertile states in Heshuo, so he won't be so spineless, right?" ”

Wang Jun said: "Emperor Jin died, the prince was expelled from Shuozhou and was not allowed to enter Taiyuan Mansion, King Lu stole the throne, Wang Yuankui supported the army to plug the well, and refused to allow King Lu's soldiers and horses to enter Heshuo, at this time, he should still be on the throne of the prince." And the Liang army invaded the north, although Wang Yuankui regarded himself as a Jin general and killed the Liang envoy first, but there was a lot of hesitation in the follow-up use of troops, until the Liang army surrounded Luzhou, its soldiers and horses did not officially kill from Taihang Mountain, there are some contradictions......"

Han Qian nodded and said: "If you want to say that Wang Yuankui killed the Liang envoy, he simply and neatly said that he had no intention of surrendering to Liang, and he should not hesitate to send troops, most of the reasons behind this are that there are differences within the Cheng German army." ”

"If there is a disagreement, it shouldn't be so neat and tidy to kill the lobbying envoy sent by Zhu Yu." Xi Ying said.

Wang Jun said: "Now it can be confirmed that Wang Jingrong is the old subordinate of the Shenling Division, if it is assumed that Wang Jingrong is making trouble inside, and even Wang Yuankui is also led by Wang Jingrong by the nose to a certain extent, many things can be explained." Killing Liang Envoy does not require many people to participate, and even Wang Jingrong can force Wang Yuankui to pinch his nose and recognize it first. The mobilization of troops and horses and the dispatch of troops from Jingcheng to attack the Liang army in the west involve a wide range of areas, and whether the opinions of the generals of the Chengde army, large and small, can be unified, and whether the preparations for heavy weapons and grain will be deliberately delayed, is not something that three or five people can secretly control......

"Are you saying that Wang Yuankui may not really want to turn his face with Liang Jun, it may be that he was coerced by Wang Jingrong with means at the beginning and had no choice, and Wang Jingrong will also force Wang Yuankui to defect to the Mughutures in the future?" Xi Ying asked, thinking about it, there is indeed this possibility, otherwise many things really can't be explained.

Wang Jun said: "I think it is indeed possible. Wang Jingrong is a former subordinate of the Shenling Division, and it is one thing that he has a deep hatred with Liang Jun, on the other hand, since he got the "Heavenly Craftsman Book" from the Late Red Mansion, he should also know that the "Heavenly Craftsman Book" has long been transmitted to Liang State. Under the personal intervention of Emperor Zhu Yu of Liang, the double-furnace iron-making and other methods have been widely promoted and applied in Bianjing and Luoyang far more widely than the Chengde army, and Wang Jingrong understands that Luzhou is difficult to defend than the vast majority of people in the north, and after the fall of Luzhou, the Chengde army only relies on more than 30,000 elite border troops and the territory of the three states, it is difficult to resist the Liang army's eastward exit! At this time, we really have to consider the situation that Wang Yuankui surrendered to Mengwu, so that Mengwu's iron hooves could drive straight from the Heshuo Plain and directly attack Weizhou, an important town of the Liang army. Of course, Wang Jingrong did have close contact with the Late Red Mansion, so for the possible actions of the Cheng German army in Dingzhou, Lu Qingxia and Li Zhihe should have prepared in advance, and we may have to keep a closer eye on the movements on the front line of Yiyang......"

Xi Ying couldn't confirm whether Wang Yuankui would easily throw himself at the Mengwu people as Wang Jun judged, but Wang Jun said that Tangyi should always keep an eye on the movements of the Evening Red Mansion in Yiyang at this time, and she felt that it was correct.

Han Qian knocked on the stone table in the courtyard, thought for a moment, and said to the guards guarding the gate of the courtyard: "You have brought Guo Rong, Feng Yi, Tian Cheng, Guo Ke, and Han Donghu here. ”

Throughout the winter, after welcoming Yuan Guowei's arrival, Han Qian did not stay in Donghu or Liyang, but soon led the guard cavalry battalion to the newly located Huaiyang County, and until the beginning of February, he stayed in the Jinwuling River Valley, the Huaiyang camp rebuilt with Shen Jiaji.

Throughout the winter, Han Qian personally urged the construction of a city in the shallow hill valley on the south side of the Wujin Mountains, on both sides of the upper reaches of the Nanqishui River.

In the hinterland of the northeast slope of Huaiyang Mountain, there are large valleys and river valley plains, but they are all mountainous areas, and the cost and difficulty of building a city are several times that of the plains.

However, the northeast slope of Huaiyang Mountain is more than 100 miles deep, and even if the population continues to move out in the future, the number of people living and breeding in the hinterland will not be less than 70,000 or 80,000, which is already the standard for establishing a first-class county.

In order to strengthen the rule over the hinterland on the northeast slope of Huaiyang Mountain, to prevent the wealthy people from counterattacking and counterattacking, and in order to exploit mining farms and develop resources on the spot as much as possible, with the help of the hydraulic power and water transportation of the upstream streams and rivers, develop smelting, casting, weaving, oil extraction, soap making, and other industries, and support the construction of the defense line to the north of Wujin Ridge, it is necessary to concentrate on building a mountain city without the need to transport all materials from East Lake.

This

It can make abundant use of the abundant labor force in the mountains and improve the situation of shortage of arable land and poverty of households.

Of course, Han Qian's coming to Wujinling in winter was also convenient to attract all the elite soldiers and horses on the eastern front of the Shouzhou Army, so as to alleviate the defensive pressure in other places.

Another thing is that Han Qian personally instructed the low-level poor and slaves in the mountainous areas west of Huazhujian.

From Huazhujian to Jiuliguan on the west side of Huaiyang Mountain, the straight-line distance is about 170 miles, which belongs to the northern slope area of Huaiyang Mountain.

Even though the mountains in these areas are quite dangerous, and the hinterland does not have as many valleys and river valleys and plains as the northeast and eastern slopes, the conservative estimate of the number of mountain people who have lived and multiplied in them over the years is between 80,000 and 100,000.

Especially after the victory of Wujinling, the Shouzhou army forcibly ordered the households in the south of Huozhou to move north, so that this time a large number of households fled into the mountains.

The river valleys and valley passages leading to the hinterland of the northern slope and the relatively gentle terrain are concentrated in the southern area of Huozhou under the control of the Shouzhou Army.

They went straight from the northeast slope and had to climb over a large group of thousands of meters, even 17,800 meters high, covered with snow in winter, and extremely rugged and steep mountains.

The severe cold weather and the thick accumulation of ice and snow were obstacles preventing the Shouzhou army generals from passing through this steep mountainous area.

However, as Wang Jun said before, before the generals of the Shouzhou army had a considerable degree of ability to withstand the cold in the cold winter season, the Tangyi army fought in the cold winter season, and actually had a greater relative advantage.

So, this winter, Han Qian still recruited elites from all departments, with more than a dozen or thirty or fifty people as a team, climbed over the mountains and mountains, entered the northern slope of Huaiyang Mountain, and took advantage of the opportunity when the Shouzhou army was unable to enter the mountains to interfere in winter, and mobilized the low-level poor people and slaves in the northern slope of the mountains to arm themselves against the oppression and exploitation of the wealthy people.

The real essence of guerrilla warfare is by no means only to send a small force of elite troops and horses to contain and harass the enemy's troops, but at the strategic level, it is mainly to mobilize the poor people at the bottom of the enemy-occupied areas to establish base areas.

While strengthening itself, it is actually necessary to greatly reduce and reduce the population and land that the enemy can control, thereby weakening the enemy's ability to obtain supplies.

Kong Xirong was mainly responsible for guerrilla warfare on the northern slope of Huaiyang Mountain, and he was also an elite who was good at guerrilla warfare in the mountains from his department.

At present, most of the generals of the Tangyi army mainly come from the integration of Huaixi refugees, among which there are many generals who are familiar with the mountains on the northern slope, and even a small number of people are the mountain people who are unbearable to be exploited by the wealthy and large households, and have escaped to find a living.

Under the cover of wind, snow and severe cold, in the name of Task Force Hornan, hundreds of small groups of elites were selected for a certain period of time to conduct assault study, and then dispersed into the north slope to join the scout horses infiltrated by the Military Intelligence Department in the early stage, and after three months, the strength of the Task Force Hornan had expanded by more than 9,000 people, with more than 30,000 people with their families, and almost controlled most of the hinterland of the north slope.

At present, the biggest problem is that the peaks and mountains and deep gorges near Huazhujian are too rugged, and a small group of people can barely pass, but the bulk of supplies cannot pass.

Without sophisticated armor and weapons, and without the supply of large quantities of materials, although the Hornan Task Force Battalion had large soldiers and horses, its combat effectiveness was limited, or comparable to that of the village soldiers.

However, fortunately, Han Qian was in charge of Huaiyang, and Xu Mingzhen did not dare to gather a large number of elite troops for the time being in addition to establishing a tighter defense line in the south of Huozhou, and forcibly attacked the hinterland of the northern slope.

This gave time for the Honan Task Force to repair and for Huaiyang to rush to repair a cliff plank road connecting the Baishui River Valley and the Yanzi Valley in the upper reaches of the Nanqishui River near Huazhujian and Tanyang Peak......
