That night, another counterattack and damage to the trench were organized in the city, but the effect was very little.

On the second day, the city seemed to have accepted its fate and never intended to leave the city again.

The excavation outside the city was completed at noon, and some mortars that were originally used to defend the city were deployed in the widened trenches. The engineers also arranged artillery positions about 250 steps away from the city wall.

The remaining soldiers continued to dig forward along the second widened parallel trench. As for whether the third parallel trench should be dug to reach the city wall to the greatest extent, it depends on the effect of the shelling.

The weather is still good this day, without wind and rain, and the scorching sun is in the sky, which is suitable for the decisive battle.

More than ten mortar cannons aimed at the city wall, and more direct-fired copper cannons were transported along the widened trenches. Once the mortar cannons began to fire, the remaining copper cannons would take advantage of the chaos to enter the deployed position and pull the defenders of the city wall into the range.

Looking at the height of the sun, Liu Finger looked at the other people and gave the order to start bombardment.

The smoke of gunpowder continued to rise in the trench, and heavy iron bombs continued to fly towards the city wall. The white smoke covered by firewood and grass piled up in front of the trench provided cover for the artillery behind to deploy the copper cannons.

"Don't be stingy with gunpowder and iron bullets. The more gunpowder is used, the less blood we will shed. Human life is priceless, so it is not considered human life. It is only considered utilitarian, and gunpowder is always cheap."

Liu Finger said this, this is the strategic guidance for the attack on Si Shang. It has always been like this. Whether it is digging trenches or zigzag digging, everything is the priority.

Through the telescope, the first round of artillery shelling caused the defenders in the city to panic. A large number of soldiers who were supposed to be deployed in the rear were sent to the front of the city wall and were ready for battle.

Through the glass of the lens, Liu Finger saw an iron bullet falling from the sky, smashing a city wall, and splashing gravel injured several people.

He shook his head, thinking that this was just the beginning, and the real tragedy would not begin until the flat-fired bronze cannons were unfolded.

I moved the angle of the telescope and looked at the artillery troops deployed there on the artillery positions. More than 60 brass or bronze artillery were adjusting their positions and angles under the push of the artillery soldiers. Several cannons at the top of the city also began to suppress and counterattack, but they had no effect.

Several iron bombs flew to the chest wall in front of them, which was piled up with thick soil. The soft soil absorbed the energy in the iron bomb and could not be bounced up.

The artillery, which had been practiced many times, took about half an hour to deploy the artillery amid the rumbling sound of cannons.

Liu Finger looked at the time. When the sun fell, it was about two and a half hours before it was dark.

He turned around and asked the adviser around him, "If there are more people in front of him, day and night, will the Zhizihao be able to approach the city wall before tomorrow evening?"

The consultant calculated slightly and said, "If there is no counterattack in the city, if our artillery can suppress the city walls, we will definitely be able to approach before tomorrow evening."

Liu Jie nodded, then thought about it, and ordered: "Let the artillery adjust the muzzle, and according to the scheduled plan, let the iron bomb bounce on the city base as much as possible to kill the enemy."

"Let the two brigades who were preparing to excavate also take shovels and picks up to speed up the excavation, forcing the defenders in the city to go up to the top of the city, threaten the artillery and let the artillery kill and injure."

"Staff members make a plan..."

He pointed to the lobe of the city defense opposite and said, "The plan is that if the enemy cannot withstand the bombardment of artillery, we will directly attack the lobe without digging the third parallel trench."

"After attacking, you must prepare a counterattack, how to build a simple defense within, and the defensive range of each unit."

"Break the surface with a point, the faster the better."

The staff members do not need to ask whether this plan must be implemented. They only need to build an implementable plan according to the ideas mentioned by Liuzhi.

The hot air balloon has been observed more than ten times in the convex angle opposite, and drawings from various angles have been drawn.

The defense system of Dangshan City has loopholes because it was transformed by the city and was not a special fortress, so there was no double fort inside, only a star-shaped structure on the outside.

As long as you break through a corner and be able to defend a counterattack, the entire defense system of the city will be completely destroyed.

To make such a plan, we need to consider the number of first camps that rushed up in the first wave, the size of the trenches they needed, how to break through the last moat of the city wall, the direction of bombardment of the artillery after attacking, the earthwork required for simple earth wall fortifications used for defense, the number of transports, and the maximum number of soldiers that can be deployed.

This is not something the coach needs to consider, he just needs to have a general idea.

Before evening, the plan made by the staff members had been put forward, and the excavation speed ahead was similar to what the staff members estimated.

Compared with the map, the senior officers of the Legion headed by Six Fingers looked at the plan and nodded.

In the plan, four grenades companies first need to launch an impact. Under the impact, a spacious trench that can accommodate about 1,000 people must be dug, and an exit that can enter and exit a hundred people at one time.

The guards were tempted to deploy a large number of troops to the ridge. The artillery bombarded for an hour and then stopped for two minutes. The guards mistakenly thought they wanted to attack the city. After enduring the artillery bombarded for an hour, they entered the ridge again.

This happened three times, and it was about noon. I first climbed the camp and started siege, and the artillery immediately changed the direction of the attack.

At the same time, during the previous bombardment, the engineer dug out the deployment trench of the mortar cannon and transported the mortar to a place closer to the city wall. Once the attack begins, the mortar cannon crosses the ridge and bombards the rear of the ridge.

After first entering the camp, they would climb the city with a brigade of the First Division. Each person carried a bag of sand and soil, and quickly deployed simple fortifications according to the company.

The remaining four brigades of the First Division then carried earth and rocks, transported upwards, and strengthened the fortifications.

Aggregate twenty small caliber and can move quickly, launching a pound of iron bullets and a part of the lightweight tiger cannon, and follow the First Brigade of the First Division to climb the city.

The cavalry was preparing in reverse to prevent the enemy from leaving the city and escaping, and the Second Division was responsible for reverse blocking.

If the enemy resists stubbornly, guard the horns, and the engineers quickly pile up Yangdi Tushan below the horns, striving to complete the construction before noon on the second day, deploy artillery troops on the Yangdi Tushan next to the horns, forming a suppression on both sides, and the infantry gradually expand their results.

After seeing it, Liu Finger clicked at a time and said, "You can delay the siege for another day. You can bombard the city with a cannon for one day first, and then choose to bombard a little hard the next day. Time is enough, so don't worry."

"What do you have any other opinions?"

The representative of the Mozhe of Peiyi Legion said: "I still play the old tune again. Once the plan is formulated, there must be no mistakes in the way of sending orders by relying on the flags, drums and the transmission methods of the command soldiers. Senior officers of each department must come to the front line in person and make a decision immediately on the premise of understanding the intentions of superiors."

"Overall, follow the plan; in terms of details, adapt to the situation. It cannot be said that the engineers were foolishly digging sheep and repairing the earthen mountain before the conquered Fortress was captured."

"It's still the same. The representatives of Mozhe from each department are on the front line, and the military chief is responsible for overall command."

This has always been the rule of the Si Shang Yishi, especially when communication means are basically based on shouting, there must be a senior legion in front to deal with various emergencies.

Liu Finger was the representative of the Mohist in the voyage back then, and he also needed to take the lead in charge. This was the case more than ten years ago, but it is still the case today.

But he is now the head coach, not the representative of Mozhe, and needs to stay behind to take charge of the overall situation. The representative of Mozhe in the legion needs to visit the front line and have their own division of labor.

Fortunately, the plan itself is linear, not nonlinear like split-headed and progressing. It is in sequence step by step, and the possibility of accidents is much smaller.

If you first climb the camp and do not capture the horns, the infantry of the First Division will not need to continue to the next step. The horns are not controlled, and the engineers will not need to accumulate sheep under the horns.

Liuzhi added: "The only thing to pay attention to is the timing of the movement of the mortar, and the possibility of the enemy trapping beasts and fighting to fight back to death. Since the artillery is the mastermind, the infantry must cover them."

"If there is no problem, there is no supplement, so vote."

After thinking about it for a while, everyone lost the rest of their opinions. After the vote was passed, the recorder recorded it as a file, and then summoned brigade-level cadres from the siege to explain their intentions clearly.

After they understand the intention, they will tell the company the purpose and convey it to each soldier, so that they can understand what they should do and agree on what the tasks of each company will do if something unexpected happens.

Of course, some details are not necessary to tell every soldier and company-level cadre, such as the gap between artillery bombardment that lure the defender into the city to gather on the city.

…………

On the morning of the next day, the artillery continued to bombard the fire to maintain the automatic cooling of the barrel heat instead of the forced cooling of oil or water for rapid fire. This bombardment lasted for half a day.

In the eyes of the envoys of the vassal states, Dangshan was like a place with fire and demons in the stories of strange stories.

At this time, the hard stones produced by Dangshan are not as soft as the soil that looks softer.

After hundreds of experiments, more iron bombs were bounced up and flew around instead of directly hitting the bricks and stones, causing the iron bombs fired by dozens of copper cannons outside the city to fly randomly on the walls of Dangshan City.

This kind of irregular flying is the most terrifying and the easiest to destroy the will of the defender of the city.
