Chapter 2614 Difficult tunnel tactics, burning down the Nanzheng grain depot

Chapter 2610: Difficult tunnel tactics, burning Nanzheng grain depot

Since the beginning of the Troubled Times, although Da Qin has not used the Zhuzi Army, it does not mean that other forces have also used it.

During the Yellow Turban Uprising, Zhang Jiao, Huang Chao, Zhu Yuanzhang and others used the tactics of the Zhuzi Army many times.

In addition, in the three Central Plains wars, Cao Cao, an expert in tomb robbing, also used the Zhuzi Army many times.

In the Central Plains region, the presence of Zhu Zijun is not uncommon, but there are only a handful of successful cases, and the reason for this is a dead man, he is Zhang Heng.

 Zhang Heng, together with Sima Xiangru, Yang Xiong, and Ban Gu, were known as the "Four Masters of Han Fu". He died in the fourth year of Yonghe (139) at the age of sixty-two.

The Yellow Turban Uprising was in 184, which means that Zhang Heng died 45 years before the Yellow Turban Uprising, and he is not in the system’s birth list for the time being. So why would he affect the success of the Zhuzi Army?

The reason lies in the seismometer invented by Zhang Heng.

During his tenure as Taishi Ling, Zhang Heng invented the world's earliest seismograph. According to the "Book of the Later Han·Zhang Heng Biography", the seismograph was made of fine copper, with a diameter of eight feet, a protruding top cover, shaped like a wine bottle, and the seal script "Mountain Turtle Bird" Decorated with images of beasts. There is a big pillar in the middle, with eight paths running beside it, which is used to shut down the engine. It has eight directions, and in each direction there is a dragon with a copper bead in its mouth. Under each dragon there is a toad corresponding to it.

 If an earthquake occurs in any direction, the copper beads contained in the dragon's mouth in that direction will fall into the toad's mouth, and the direction of the earthquake can be determined.

 After testing, it is consistent with the established system and is like God. This has never happened since the beginning of recorded history.

Once upon a time, a dragon suddenly appeared, but the earth did not move. The scholars in Luoyang blamed it for not believing it. A few days later, the messenger came, and sure enough, an earthquake occurred in Longxi, and everyone was convinced of its miracle.

Since then, the imperial court has ordered historians to record the places where earthquakes occurred.

 Zhang Heng is also a human being, not a god. The seismometer he invented also has certain errors and is not 100% accurate.

 After more than 40 years of evolution, until the beginning of the Troubled Times, with the improvement of Gongjia and Mohism, the seismometer also evolved from the initial 1.0 version to the current 3.0 version, and was also used on the battlefield.

 Previously on the battlefield, when encountering the Zhuzi Army, people with profound skills and hearing talents were usually asked to monitor underground vibrations at all times.

 There are obviously not many masters who are talented in listening and have profound skills, and people always take a nap when they are tired.

During the Yellow Turban Uprising, when Ying Wen led the Han army to defend Hangu Pass, his men were short of manpower to monitor underground earthquakes. In order to deal with the tactics of the Yellow Turbans, Cao Cao was the first to propose an improved seismograph to detect underground earthquakes. This was also the first time. Once the seismometer was used in tunnel warfare.

 In the following three wars in the Central Plains, the Ming army once again improved the seismograph to prevent the Wei State's Zhuzi Army.

 So, the current 3.0 version of the seismometer can not only detect earthquake preparedness, but also detect the underground of the city where it is located, whether there is any earthquake sensation due to large-scale excavation, and the specific location.

Once there is a seismometer in the city and the Zhuzi army digs under the city, it will basically be detected by the seismometer, so arrangements can be made in advance.

Whether it's water cans, fire attacks, or smoke, for the underground soldiers, it can be said that they have a narrow escape.

Since then, as seismograph technology has become more popular, not many forces are using the Zhuzi Army because it is difficult to fulfill its original role.

However, when all countries eliminated the Zhuzi Army, Li Jing did the opposite and ordered Tu Xingsun to build a total of 3,000 people of the Zhuzi Army.

Li Jing naturally knew that it would be difficult for the seismometer to work in Zhu Zijun, but he obviously had more profound thoughts, and the Zhu Zijun he built was not an ordinary Zhu Zijun.

The Plug Zijun built by Li Jing is a super Plug Zijun who was taught the earth walking technique by Tu Xingsun. Its mining efficiency is far beyond that of the conventional Plug Zijun.

Even in the Shangyong area where the ground is full of rocks and the soil is extremely hard, it only took the Great Qin Zhuzi Army a month to dig a tunnel that was fifty miles long. They dug an average of two to three miles a day and bypassed it perfectly. West City Defense Line.

With such a huge amount of work, if the Wei Guo Zijun were to dig, with the same number of people, they might not be able to dig through it even in the first half of a year. This fully shows the efficiency of the Qin Zijun.

Although the Zhuzi Army dug tunnels to bypass the West City, they could not dig into the West City because once they dug underground, they would be detected by the seismometer in the city.

In addition, even if there is this tunnel, Han Xin's troops cannot be allowed to move to the rear of Xicheng through the tunnel, and then cooperate with the Qin army in front to attack Xicheng from both sides.

The tunnel is fifty miles long. Even if ordinary Qin troops other than the Zhuzi Army can walk, they will definitely not be able to move fast, and they will not be able to carry large ordnance and too much equipment.

Therefore, it is destined that only a small number of people can come through the tunnel, because after coming over, food and grass will be a big problem that is difficult to solve.

Moreover, after coming here, there were no large-scale siege equipment. With only a sword, it was impossible to break through the West City, which was easy to defend but difficult to attack, even if it was attacked from both sides.

Li Jing never thought of relying on this tunnel to transport Han Xin's troops to the rear of Xicheng. Firstly, it would be difficult to function, secondly, Han Xin would not agree, and thirdly, he never thought of breaking the situation in Xicheng from the beginning. What he really wanted was The target is actually somewhere else.

The moment the tunnel was dug through, all the Zhu Zijun breathed a sigh of relief, and Longxuhu even said excitedly: "Damn it, after digging for more than a month, it's finally dug through."

Li Maozhen glanced at Xicheng in the distance and said solemnly: "This is just the first step of the Governor's mission. Whether the mission can be successful depends on the next actions."

Tu Xingsun's operation, in addition to himself, Li Jing also sent Long Xuhu and Li Maozhen to assist him.

Li Jing sent Long Xuhu over because of his good relationship with Tu Xingsun, and sent Li Maozhen over because he was familiar with the terrain of Hanzhong.

Li Maozhen's father, Li Xiaogong, was the governor of Hanzhong, and Li Maozhen also took his father to escape from Hanzhong to avoid being hunted by bad people, which shows how well he knew the topography of Hanzhong.

With the war between Qin and Shu, Hanzhong County has already been under martial law. Even if the Qin army has not yet conquered Yangping Pass and Xicheng, the defenses of the cities in Hanzhong are extremely tight.

If Tu Xingsun wants to complete the role assigned by Li Jing, he must lead his three thousand soldiers to go deep alone. But if he wants not to be discovered by the Shu army in Hanzhong, he must have a guide who is familiar with the terrain of Hanzhong, and Li Maozhen is The best guide ever.

Looking at Li Maozhen's handsome face, Tu Xingsun felt envious and jealous in his heart, but now was not the time to be distracted by such things. "Brother Maozhen, the food and grass we carry is only enough for half a month. The task must be completed within half a month." Tu Xingsun said.

Li Maozhen nodded, and then opened the map. In addition to all the cities in Hanzhong, there were also many forts and camps listed on the map.

The Shu Han Dynasty has built the entire Hanzhong into a fortress. In addition to Yangpingguan on the northern line and Xicheng on the eastern line, it has also built hundreds of Wu forts and dozens of camps in Hanzhong to prevent the northern and eastern lines from attacking. There is a flaw in the line.

 After all, if anything goes wrong at Yangping Pass and Xicheng, these arrangements can also delay the fall of Hanzhong and buy time for the Shu army to retreat.

Tu Xingsun saw that there was a Wu Fort built by the Shu army twenty miles away on the map, and he couldn't help but exclaimed: "The location of this Wu Fort is so tightly blocked, can we get around it?"

"Yes, but not during the day. You have to do it at night."

Li Maozhen finalized the course of action in one sentence, and the next step was to rest and wait for dark.

After dark, Li Maozhen, Tu Xingsun, and Long Xuhu, with three thousand soldiers dressed in black, sneaked towards Nanzheng and successfully bypassed the exploration of Wubao ahead, and a man appeared on the way. It was a small accident, but we got through it safely.

In this way, in order to avoid detection, Li Maozhen and his party rested during the day and traveled at night, climbing over mountains and ridges. After five days of marching, they finally sneaked to a ruined temple five miles away from Nanzheng.

There are still dozens of beggars in the ruined temple. If they could enter the city normally, they would go into the city to beg. But now that Nanzheng is under martial law and no entry or exit is allowed, they can only rest in this ruined temple and wait for the city to open before entering the city.

For these beggars, life is hard enough. They have tried their best to stay alive, but God is still unwilling to let them go.

“General, there is a group of beggars in the temple.”

Hearing this, Li Maozhen, Tu Xingsun and Long Xuhu looked at each other and made the same decision, which was to silence him.

Their mission this time was too dangerous. They went deep alone and sneaked into Nanzheng, the rear area of ​​the Shu army. There were tens of thousands of troops in Nanzheng city. Once their whereabouts were exposed, they would really have no way to go to heaven or earth.

 So, whether it is for the mission or for their own safety, they cannot leave any consequences.

The beggars had no idea what was going on. They were all silenced by the Qin army in their sleep and died quietly.

 After wiping out all the beggars, Li Maozhen, Tu Xingsun, and Long Xuhu each led their teams and continued with the next plan.

The ruined temple is located five or six miles north of Nanzheng City, and the soil around the miracle in Nanzheng City is not as hard as Yangpingguan and Xicheng.

With the excavation ability of the Zhuzi Army and using the ruined temple as the starting point, they could dig to the bottom of Nanzheng City in less than one night. Coincidentally, the Shu Army's grain depot was also located in the north of the city.

The grain depot in Nanzheng City was the goal of Tu Xingsun's trip. As long as the grain depot could be burned, the Shu army would be short of food, and it would be only a matter of time before Hanzhong fell.

However, they cannot dig directly. After all, there must be a seismometer in Nanzheng City. Once they dig under Nanzheng City, they will be detected immediately.

In addition, the ruined temple cannot hide three thousand people, so the top priority is to determine the excavation plan and first dig an underground space large enough to accommodate the excavation of three thousand soldiers, otherwise they will be exposed at dawn.

Although the Great Qin army was able to dig into Nanzheng City in just one night, in order to burn down the Nanzheng grain depot, they did not dig directly into the city. Instead, they divided their troops into three groups, one heading north and the other two heading east and west. roundabout.

After three days of excavation, the three tunnels have been dug. They can dig into Nanzheng at the same time only with Tu Xingsun's order, but the Shu Han side has no idea about this.

 The ninth day, late at night.

“Send out the carrier pigeon immediately and inform the Governor. The plan is in its final step.” Li Maozhen said solemnly.

"good."

Tu Xingsun nodded, and then ordered someone to release the carrier pigeon.

 The night was too dark, and the homing pigeons sent by Tu Xingsun were gray, so they would not be discovered.

“Success or failure depends on this, dig in, brothers.”

Following Tu Xingsun's order, the three thousand soldiers were divided into three groups, north, east and west, and dug together towards Nanzheng. It was not long before they were detected by the seismometer in the city.

In Nanzheng, in the Hanzhong Prefecture, there is a hall dedicated to placing seismometers, and there are people monitoring it 24 hours a day.

There are three groups of people monitoring the seismograph, with two people in each group, rotating every four hours, and they have only one task, which is to keep an eye on the seismograph.

　　咚…

The copper pills from the northern toad's mouth suddenly fell from the seismometer, which frightened the two guards present into a cold sweat. After all, in addition to detecting earthquakes, the seismometer also has the function of detecting pegs.

 Now that the copper pills are falling in the north, doesn't it mean that someone is digging a tunnel in the north of Nanzheng?

 The two guards were immediately ready to report, but before they could walk out of the gate, the copper pills from the mouths of the two toads fell one after another.

“What’s going on? Why did three copper pills fall at the same time?”

“Even if it’s Earthquake and Zhu Zijun, only one of them should fall. How could three of them fall together?”

“Is this seismometer broken?”

“It’s possible, but we’d better report to the prefect first.”

After some discussion, the two men immediately reported the news that all three copper pills had fallen on the seismometer to Liu Zhang, the prefect of Hanzhong.
