In the evening, in the large camp on the southern outskirts of the city, the defenders were heavily guarded, and the long circle next to the camp was crowded, and many young people broke the ice to get water by the Rushui River, and then used wooden barrels to hold water and picked it up on the long wall, and then splashed the water on the soil slope on the enemy side.

The first day has passed, but the weather is still cold, and the water spilled on the dirt slope will freeze into ice after a night, and in the next day, the outer frozen soil slope will become very slippery, and it will be even more difficult for the hanging gourd defenders to break through.

After the latest reinforcement, the thickness and height of the long fence have increased, and the earthwork comes from the widening of the trench, which is now like a thick iron chain, firmly locking the hanging gourd.

The eastern, southern, and western battalions at the Changwei also dug deep trenches on the periphery, and even the Fengsui Xiaozhai on the edge of the Changwei also strengthened the defense facilities, and arranged a large number of antlers, together with the wooden stakes originally laid outside the Changwei, forming a dense circle of horse rejection arrays.

These measures are not only to prevent the garrison in the encirclement from breaking through, but also to prevent foreign enemy reinforcements from breaking through the encirclement, which is not unfounded, because the enemy reinforcements are really close to the hanging gourd, and the distance from the city is a day's march.

"Anyway, we have to close the sluice gate to store water, so why do we need to sprinkle water on the dirt slope? Isn't that redundant? ”

"Oh, you're complaining a lot! The officers and soldiers will do whatever they tell them to do, and they will not listen? It's itchy, isn't it? ”

"What are you yelling about, I'll tell you what you are yelling at!"

"Noisy, noisy! When the officers and soldiers heard it, they grabbed and whipped it, and it was noisy! ”

In the busy team, several young men were muttering in a low voice, on the day of the first day, everyone had to take a good rest, but now they have to brave the wind and snow to fetch water and sprinkle water, which is nothing, the key is that the officers and soldiers will close the gate and store water again, so everyone's hard work is in vain.

Every festive season, the young and strong people are far away from their hometowns, unable to communicate with their families, do not know how their families are doing now, they have spent the first day in another country, and they do not know when they will be able to return to their hometowns.

The hanging gourd city in front of him is like a stone in a thatched pit, smelly and hard, the official army has been attacking for several months, and now the enemy's reinforcements are coming again, and the official army has been defeated in Chai Village, and now it is approaching the hanging gourd.

Seeing that the big war was imminent, everyone was going to follow the officers and soldiers to a wild battle, and life and death were uncertain, and everyone's mood became more and more depressed.

said that the military service and labor for a month and a half would have been overtime, but no one dared to complain, so they could only wait silently.

And now it is going to fight a field battle, it is not a joke, once there is a big defeat like the battle of Shibamura, then the field will be empty, and I don't know where to run, the enemy soldiers are riding horses, how can their two legs run more than four legs?

"What do I do, you ask? It's easy to do, pretend to be dead. ”

"Play dead? What if someone or a horse tramples you to death? ”

"That's because you don't give much incense to the Buddha on weekdays, you deserve it, and you can't complain about others."

"Pretending to be dead and hiding for a while, what about after that? The big guy is penniless and has nothing to entangle, how can he get back to his hometown? ”

"Which side wins, vote over there, it's better to die than to live, whether you can return to your hometown alive, then it depends on whether you are sincere in burning incense to the Buddha on weekdays, if you are sincere, the Buddha will naturally bless you, and only burn incense now? It's late! ”

It's better to die than to live, although everyone's life is not good, but as long as you live, you can be with your relatives, a young man listened to the discussion of his companions, and couldn't help but be a little silent.

He is in his twenties, which is the age of strength and blood, and the demand for women is becoming more and more intense, but because his family is poor and cannot afford to marry a daughter-in-law, he and his companions have peeked at the widow in the village taking a bath, but when he really wants to, he can only rely on his hands.

He died without tasting a woman, he really came to this world for nothing, he was unwilling, but he was helpless.

After the battle of Chai Village, the official army somehow abandoned Song Ping, so that just after the first day, the enemy reinforcements approached thirty miles away from the southern suburbs of Xuan, and the Nanda camp bore the brunt, thinking of the battle that was about to break out, he sighed.

Kick the stone in front of him down the dirt slope, looking ahead, the sun is setting, the sky is dark, the city is shrouded in the afterglow of the sunset, exuding a golden light, a high tower in the city is particularly conspicuous.

This tower, in fact, is not very high, it seems that it was erected not long ago, otherwise it would have been smashed by the trebuchets that the officers and soldiers used to fire day and night, he looked at the tower with a blurred outline, and involuntarily wiped his eyes.

Why does it seem that there is a light on the top of the tower that keeps flickering? Could it be that I'm dazzled?

。。。。。。

In the Hanging Fortress City, on the high tower called the 'Communication Tower', several guards are 'sending and receiving' messages on the top floor, they are the 'Sending and Receiving Group', operating cross-era communication tools at this time, and conducting 'real-time contact' with friendly forces nearly thirty miles away in the southern suburbs of the Hanging Fortress.

The device they operated looked like a large billboard with lamps, and it had an awkward name that was difficult for the average person to remember:

Mass-produced portable battlefield advanced multi-functional integrated optical long-distance communication, command and control system.

The name is too long and awkward, so it has a strange abbreviation, called "Xishanai".

In fact, this device is a synthesis of high-powered telescopes, signal lights, and cottage "four-digit display boards", the format of which is "day by day", and the display content is numbers, which are 'Arabic numerals' that few people know in the Central Plains in this era.

The signal light and the "digital display board" light source are candlelight, which is amplified and redirected by a complex optical path, and finally displays four digits on the digital display board.

This four-digit number is the Chinese character code, and the receiver observes and records the Chinese character code through a high-powered telescope on the same model, and then translates it into text according to the code table.

The four-digit Chinese character code, derived from the difficult birth of the cable telegraph, the cable telegraph encountered technical obstacles, far from the practical period, it is very likely to be stillborn, but the Chinese character telegraph code is already a finished product, it is easy to transfer flowers to the 'optical communication'.

The tram carriage railway from Daye to Wuchang to Xiakou has such a device at the stations along the line to assist the tram carriage scheduling and ensure that the train is not congested.

Of course, this method of communication has disadvantages, but the advantages outweigh the disadvantages, and it can achieve 'long-distance' communication of more than 30 miles in good weather conditions and unobstructed line of sight, and the better the weather conditions, the farther the communication distance.

There are many difficulties in this technology, and the most critical point is that the two sides who are about to communicate must find the location of each other's 'Xishan' device through high-powered telescopes, which must agree on the approximate location and direction in advance, and rely on the signal light to 'attract' the other party, otherwise it will be difficult for the two devices to 'dock' successfully.

Not long ago, the soldiers who left the Hanging Gourd in a hot air balloon to break through to the south wanted to deliver the secret letter to the friendly forces in Guangcheng, and according to the pre-planning, the Tiger Forest Army of the King of Xiyang would arrive in Guangcheng with a few 'Xishan Ai'.

In the secret letter, Yu Wenwen indicated the approximate location and location of the reinforcements' optical communication in the future, and now, the Shannan army, which was close to the Hanging Gourd, successfully docked the 'Xishan Ai' carried by the army with the 'Xishan Ai' on the high tower in the Hanging Gourd City this evening.

In the hut under the tower, Yu Wenwen was looking at a thick small notebook, which was the text content he was going to send to the reinforcements, sprinkled with thousands of words, writing about the situation of the enemy and us now.

These contents have been compiled into Chinese character codes, and the sending and receiving team is now operating 'Xishan Ai' on the tower to lay out a four-digit Chinese character code, which may have to stay up all night to send out, and at the same time, they have to observe the Chinese character code put out by the other party's device, and then translate it.

In this way, Yu Wenwen can know the situation in the outside world.

This set of devices, Yu Wenwen is intended to be put into the transformation of the post station in the future, in order to speed up the speed of message transmission, after several years of development, the level of practicality is very high, the finished product is not, the operator has been trained.

In front of the siege of the enemy, the 'Xishan Ai' finally came in handy, Yuwenwen can use this to communicate with the reinforcements outside the city, to achieve long-distance communication, command, this communication device, under the pretext of C3I system, in fact, is not related.

He was inspired to create this installation from a world-famous book.

Yuwen Wen closed the small notebook, handed it to the compiler on the side, put on his cloak, turned out of the room, and looked at the flickering light on the tower, and couldn't help but be full of malice.

Deliberately let reinforcements come over, wanting to besiege the city and send reinforcements?

I'll show you the big stallions... The upgraded version of the communication device in the era of Alexandre Dumas is amazing!
