Soldiers are impermanent, water is impermanent, and the essence of the way of using soldiers is the word change.

The city of Constantinople is high and thick, and there are towers equipped with ballistas, if you attack directly, with the raining ballistae and strong bows on your head, it is already good to have 600 kills in a thousand people to reach the city wall, and the moat of Constantinople has been cleared, and it is not cost-effective to fill the river with human heads at the risk of amazing casualties.

In the battle of the Muyak River a while ago, both the Great Min and the Arabs took the trench warfare to the extreme, and Li Jie's ears and eyes were touched, and Li Ji also sacrificed this magic weapon at the beginning, and the trench dug deep in the ground almost hid the whole person in the ground, not even showing his head, let alone bows and arrows, and ballistas could not be hit.

In the last three days, the Roman defenders at the head of the city had no choice but to watch Li Ji's army advance like a groundhog on the tidal plains by the city, approaching the base of the city wall.

However, depressed for two days, Constantine IV was not too worried, there must be advantages and disadvantages, using trenches to transport troops, the heavy equipment of the Fujian army such as building cars, ramming hammers and other big guys can not be transported under the city, and the city wall of Constantinople is made of Mediterranean white stones, and the gaps are also sealed with volcanic ash and Roman cement, which is very strong, and the Fujian army can't open it for a while.

Not to mention the fact that there is a deep moat! The moats of the Min people could not lead directly to the city.

The Damin Legion was much larger than Caesar's Legion that year, and the civil excavation of three or four hundred meters was smaller than the amount of work of Caesar's Legion in the two sandwich walls in the Alesian War at that time, 200,000 people worked in shifts, a week, through a radius of more than ten miles, and the labyrinth-like seven trenches were also hit to the edge of the moat.

In the midst of the noise, countless earth and stones were loaded on the shields, and crackled from the mouth of the trench into the trench, and the water of the moat was drawn from the Golden Horn, and there were many sea fish in it, and the stones were thrown into it one by one, and several unlucky big fish were drowned under the stones.

The trench was five meters long, and in half an hour, the mouth of the seven trenches was also piled up with a small half of the passage, but before the Fujian soldiers rushed out with excitement and roaring, the Roman defenders who had been waiting on it also shouted together, and in an instant, thousands of feather arrows and ballistas were overwhelming to the exit.

More than a dozen shields were immediately scurried around by balls the size of ballistae and human heads, and these days I watched the Fujian army digging under my nose, but I couldn't reach it, and the Roman defenders were really deflated, and they all vented out at this time.

Fortunately, they were in a hurry, and the Min army had just shown their heads and came over, except for a few front-row shieldmen who were broken and vomited blood by the big and small stone balls in their heads, the rest of the digging sappers retreated.

Around this, the crackling arrows behind the exit, the sound of stone bullets still came continuously, and it lasted for more than ten minutes before stopping, and the sturdy rammed earth at the entrance of the passage was smashed by the Fujian army with a shovel was torn apart and collapsed in a large section.

The difficulties were quickly reported to the headquarters of the Chinese army, and listening to the reports of the front-line troops, Su Dingfang, Li Yexu, Li Chong and other generals all showed embarrassment on their faces.

It took a whole week and hundreds of thousands of labor, but in the end it was the result, although the loss of the siege was saved, but now the seven gaps have become the concentration of Roman firepower, which is not conducive to the Fujian army to fill the moat and attack the city.

However, it is somewhat similar to the game of whack-a-mole in later generations, with a total of seven holes, and the Min army as a gopher will always emerge in these holes, and as soon as the Min army emerges, the hammer of the Romans who concentrate on guarding the hole will be smashed down, and the head of the Min army will be broken and bleeding.

Of course, the Min army does not lack warriors who are not afraid of death, and if you use human lives to fill it, the seven passages will not be filled in, but this also loses the meaning of digging trenches to cover, and forcing the corpses of the Min soldiers to fill the city, how will the generals command the army in the future?

This is the battle plan formulated by Li Ji, and now it costs a huge amount of manpower and material resources but it doesn't work, and if you backfill it, you have to spend a huge amount of manpower and material resources, you must know that when the army moves, there are ten thousand taels of gold, and it costs a lot to support the army in European expeditions, and every day is a thousand gold.

Because of Li Ji's face and majesty, the generals are not easy to blame, but they inevitably have complaints in their eyes.

Li Yexu was still anxious for the public, and when he saw that it was cold in the tent, he rushed forward after thinking for a while, and said in a round, "Duke Chu doesn't have to worry, it's a big deal to dig more tunnels under the city, so that the Romans can't figure out where we are attacking, so they will naturally mess up." ”

This is a good way, although it takes some effort, but it can be regarded as a proper remedy, and Li Yexu also inspired the generals' ideas, and was also sent to the front line of the Shenwei general, the Goguryeo Xiaoye Tiger also walked out of the generals, and proposed with full confidence: "My army has carried enough tiger squat cannons, which can be set up in the trench, and ten thousand cannons are fired in unison, so I don't believe that he can't be killed by the Roman devil!"

This suggestion made everyone's eyes shine, the power of the Great Min Tiger Squatting Cannon is obvious to all, and this lightweight small cannon is cheap to cast, and the Great Min Legion also carries a lot, but although the cannon has a very low lethality to the city wall, it can not stand up to ten thousand cannons in unison, the only drawback is that the firing range is too short, flat fire can hit about five hundred meters, if you need to attack a city wall such as Constantinople, but you need to break through to one or two hundred meters, the muzzle of the gun is high angle to the sky, like a mortar cannon and the conscience cannon used by the People's Liberation Army in the Huaihai Campaign, in order to have an effect.

However, this is not a problem at all, the trenches under the city wall are zigzag, and it is enough to put a thousand cannons, and with the fire coverage and rate of fire of the tiger squat cannon, Damin can completely create a death section on the city wall, and how many trenches and moats will be filled in at that time.

Listening to the generals, you and I added for a long time, Li Ji, who had always seemed to be fine, couldn't help but nod his head with satisfaction, until everyone's attention was focused on him again, Li Ji smiled and opened his mouth, but he rejected Xiao Yehu's suggestion.

"General Shenwei's suggestion is good, but it needs to be used later, you can't startle the snake in advance, the proposal of the virtuous nephew is indeed ignored by the old man, you can send someone to open up more exits!"

However, Li Ji's old face showed a sinister smile, and the old guy said in a gloomy voice: "But everyone has been digging for so many days, after all, it has been hard, give the whole army a holiday this afternoon, continue to dig in the evening, and fill the trench under the cover of night!"

The night attack was indeed conducive to cover, but the generals were still not very optimistic about the effect, but since the general manager of the march and the commander-in-chief of the three armies had set the offensive strategy, the generals were not easy to oppose, and they all responded with a dull bang and retreated.

After many days of excavation, they could finally rest for a while, and the Fujian troops who had been tired for many days were also relieved, and took time to take a shower one by one, and hung long clotheslines in the camps of the legion.

In some tents, there were also many sergeants who were like mud monkeys, and the mud on their clothes and armor and the strong smell of sweat on their bodies were actually a lot more smoky than others, making the firehead army in charge of the army's public bath scold their mothers.

In a relaxed afternoon, it seemed that the Roman defenders at the head of the city were relaxed, and it seemed that on this day, there was finally no need to be nervous to guard against fighting again.

However, that night was just three poles on the moon, and it was not so dark that he could not see his five fingers, and in an instant, on the position of the Fujian army, the sound of hoes and shovels suddenly made a loud noise, and the soil of countless shovels was raised from the tunnel, and a spade and shovel of ash were thrown out, and at the same time, the Fujian army was also like a rabbit that suddenly rushed out of the crypt, and countless figures rushed out of the trench mouth to cover with the ashes and rushed to the moat.

Who knew that the head of the city suddenly rang with a bang, countless lamps and candles were lit up in an instant, and countless Roman archers seemed to fall from the sky, aiming their feathered arrows at the city.

"Min dog, go to hell!"

A Thracian general shouted proudly in his local accented Greek, and immediately fired thousands of arrows, and the ballistas on the city also let out a deafening roar, and countless stone bullets smashed into the moat and smashed into a column of water, and more than 100 Fujian troops who rushed out were immediately drowned in the attack.

The Min army under the city seemed to be blinded, and it was silent for a few minutes, and suddenly a miserable roar suddenly remembered, as if revenge, more Min troops were not afraid of death from the mouth of the passage, which was in the hands of the Roman defenders, and the ballistae were more concentrated at the mouth of the passage, and boxes of arrows were carried to the city, and the archers were like machines, and a row of shots immediately retreated, and they rotated back and forth, and the points were exactly the same.

The Fujian army that rushed out was again killed and wounded, and fell to the ground in the dark night.

But this night, the Min army seemed to be really stimulated, going forward one after another, even if one team after another died in the moat, it would never stop, the ballistas and feather arrows on the city head did not stop, and the archers on the city head even killed red eyes, dropped the bow and arrows, grabbed the rolling stone and smashed it down.

Charging and shouting shook the night sky.
