"Boom. Rumble. "On the artillery position of the 26th Regiment, the artillery of the Qin army arrived and fired at close range. They were armed with light artillery with direct fire. The artillery could only blast through those walls by firing at close range.

The artillery equipped by the Xiongnu cavalry was a relatively mature rear-loading artillery of the Qin army, but it was not the kind of metal artillery shell, and in order to reduce weight and further save costs, paper shell shells were used flammable. However, there is a detailed differentiation of the types of shells. Solid shells and grenades became mainstream, and of course there were other special types of shells, but basically there were two main categories of this equipment.

"Whoosh." Artillery shells whizzed across the infantry positions.

The 26th Regiment of Hun soldiers, on the horse is cavalry, dismounted is infantry, Qin Jun believes that the Hun cavalry unit in the suppression operation, must have a certain infantry combat ability.

"Sir, when are we going to attack?" Meng Du asked his commander, Engineer Captain Shirakawa. He was the only engineer unit in the 26th Regiment.

Their task was to find a way to blow up the opponent's walls after the artillery attack, as their commanders feared that the bombardment would not further damage the walls. So, he decided to use the easiest way to blast it out. Light artillery, although highly mobile, was not powerful enough. This is the disadvantage of all light artillery, originally the artillery only provided limited firepower, and was not planned for siege operations at all, if it was specialized in siege operations, it would need to be specially equipped with large-caliber mortars, but the movement speed was terrible slow. Cavalry units would not have asked for such weapons.

"When the shelling stops, I think we'll be much safer." Shirakawa said. He was originally a university student, studying civil engineering. It's mainly about construction, but because of military service, because of military service, the military will provide part or all of the tuition so that he can graduate. So, Shirakawa came here. However, for him, the sappers were mostly sabotage, and the construction rarely appeared in his hands, burning down the houses of the Dawan people. Destroying their walls, most of the things he was doing now were roads, and he didn't have a clear task to tell him to repair them.

"Sir. Personally, I think. Meng Du shook his head and said.

"Sir, I think we should take advantage of this time to go to the front line and set up an ambush, once the artillery fire stops, we will go up and load the explosives, and then take the opportunity to ignite and blow up the city wall, in this case, we will be much safer." Meng Du suggested.

"It's dangerous to do that." Shirakawa said.

"But sir, we're safe, because those Dawans are hiding from artillery. They will dodge, and in this case, the forward position will be a gap. This will help us to deploy explosives, and on the contrary, if we blindly wait for the artillery to come before advancing. I'm afraid to do so. Meng Du said.

"We're going to miss out on the best opportunity." Meng Du said worriedly. He was a Hun and the only sergeant of the 26th Regiment. He is from Simon State, a mining area. He is the best demoman they have in their area, mainly responsible for blasting mines, and is an expert at playing explosives.

"But that's very dangerous, and I don't want a dangerous situation for my troops, it's not good for us." Shirakawa said.

"Sir, listen to me, I invented a tube myself, I have seen it, the artillery uses solid ammunition, they have opened some small holes in it, we can use these holes, carry out a secondary blasting, I don't think it's a big problem. We can open up such a situation. Meng Du said.

"Yes." Bai Chuan still emphasized danger, perhaps because of the lack of battlefields, but Meng Du had experienced many explosions, and he was used to it.

"Sir, this is very important to us, if our regiment wants to enter it now, we must open this wall, and he has become the biggest obstacle in front of us." Meng Du further persuaded.

"The task of our engineer company, that's it. Sir. Meng Du said. The Hun cavalry regiment, they only received grenade training, but they had little contact with blasting training, or there was none, many Huns played, but did not really learn blasting. Therefore, the task of the sappers remained to blast. For the construction of fortifications, they do not need.

"Okay. Maybe you're right. I agree to do so, but you have to be safe, you are the only sergeant in the whole regiment. I don't want to see casualties. Captain Shirakawa finally agreed.

"Thank you, sir." Meng Du said happily. He immediately summoned his men, a squad of fifteen engineers, who reinforced their superiority in firepower, and then approached their target during the intervals of continuous bombardment by the Qin artillery.

"Whoosh." After the bombardment of a shell. The artillery positions of the Qin army temporarily stopped firing, and the light artillery used steel, which is relatively cheap, but it is a special kind, and there have been several accidents on the battlefield in Liaodong, and the artillery lock will explode after continuing to fire for a period of time. The artillerymen were wounded by this. Despite this problem, such artillery was still equipped with a large number of Hun cavalry units, because they could not do without artillery support. In such a situation, the artilleryman came up with a trick to stop firing for a while, and then wait until the barrel cooled down and fire again. And such intermittent firing had the unintended advantage of being that after the bombardment, the enemy always wanted to return to his position quickly, but soon the artillery fire came again, and after several times, the enemy generally waited for a while.

"Alright. Do you know what we do? Meng Du asked.

"Got it, sir." Jin Da, the leader of the engineer squad, nodded and said. He was holding a blaster made of hollowed-out bamboo, as it would speed up the speed at which they could reload the explosives, which they could quickly detonate by stuffing them directly into the hole.

"Alright. Work. Meng Du waved his arms, and then the five of them quickly stepped forward, and the first thing they looked for was the hole made by the cannonball. Then they took out some small explosives in the shape of a cylinder. Stuffed, lit.

"Boom." A dull explosion was heard. The entrance to the cave has widened a lot. Immediately after that, they carried out a second blasting.

"Boom." Explosions were heard.

"How?" Meng Du asked loudly.

"One more blast will do." Squad leader Jin shouted loudly.

"Whoosh." That's when it happened. Artillery is again in full swing.

"Looks like we're going to have to stop." Jin San shouted again. Explosions began to be heard. The walls of the Dawan people were almost unable to withstand the artillery attack.
