In the face of the Ming army's tactics of digging the city wall, Andre really had no way at all, not that this tactic was clever, mainly because the grenades of the Ming army were too powerful.

If you want to stop people from digging the city wall, you have to be able to get close to the city wall, and when he sends people close to the city wall, it is a black pressure grenade, and when he sends people close to the city wall, he presses a grenade, and the soldiers who come down the first floor in two rounds are almost all injured, which is how to stop him.

The artillery can't hit at all, the musket may be able to hit it if you think of a way, the problem is that the soldiers of the Ming army must be hiding under the siege vehicle to dig the city wall, the siege vehicle that cannonball can't hit, what's the use of shooting a few shots, it's a waste of bullets.

That's all there is to the weapons and equipment of the Tsarist Russian Army, and Andrei has thought of all the methods he can think of, but it is useless

He really had nothing to do, so he could only wait in fear, and when night fell, it would be impossible for the Ming army to fight at night!

It is true that the Ming army will not fight at night, firstly because there is plenty of time, and secondly, to prevent sneak attacks.

The second day of the offensive and defensive battle of the eighteenth fortress slowly ended in this strange atmosphere, the Ming army did not launch any other attacks, but sent 10,000 people to dig the city wall every two hours, and the Tsarist Russia did not have any special action, just a few cannons indiscriminately when the Ming army changed shifts, and it was simply impossible for the moving siege vehicle to hit a target at the same time with several consecutive cannons, and they wanted to tell the Ming army more in this way: We will not give in!

In the evening, the Ming army finally collected the troops and went back to the camp to rest, and Andre had the courage to let him and a team of guards down the city wall with a frame to see the progress of the Ming army digging for a day.

Good guys, the first layer of the city wall has been dug out by the Ming army more than a dozen huge holes, which are one person high and three or four meters deep!

What to do? Tsarist Russia did not have cement at this time, and the city wall could not be repaired well in a day or two, so he could only organize people to take turns to hang down the city wall, pile back the excavated soil and stones, and block it indiscriminately.

The results of 30,000 people digging in turn for nearly six hours can be imagined, Andrei commanded the 3,000 soldiers who were not injured to work for a night, and only filled half of the big holes that were dug out, which were not filled at all, and the soil and stones were not pressed very tightly.

Early the next morning, at midnight, the Ming army came up in high spirits again, and Andre could only endure sleepiness, dragging his tired body, and continued to watch, or wait for the Ming army to dig the city wall.

Fortunately, the Ming army did not intend to change tactics, they still focused on digging holes in the city wall, and there was no sign of taking the opportunity to rush up, the only thing that is a little strange is that the Ming army seems to have been digging deep, and not digging up, the first layer of the city wall is also ten meters high, they dig like this, it is impossible to dig the city wall at all, Andre is very puzzled by their behavior, do they want to dig directly under the wall of the second layer of fortresses?

The next day passed in this strange atmosphere, and the Ming army did not play any moths from beginning to end, but the personnel were replaced and more diligent, from the original two hours to change shifts, to one hour to change shifts.

For this situation, Andrei can only guess boringly, maybe they are tired of digging.

In the evening, the Ming army collected his troops again and returned to the camp, and Andrei once again asked him to hang him off the city wall to see the situation.

This time the Ming army actually moved all the excavated earth and stones, and the city wall was empty, leaving more than a dozen huge holes there, as if a group of demons opened their mouths in the dark night, and were laughing at him there!

Their equipment is not as neat as that of the Ming army, who has nothing to prepare so many hoes, even if there are so many hoes, how many earth and rocks can three thousand people dig up in one night to fill the huge holes.

Andre gritted his teeth, simply, go to sleep, it just so happened that he didn't rest last night, the Ming army will dig if he likes to dig, anyway, it will take at least ten days to dig under the second-story city wall, it's still early, let's see it then.

Sun Chuanting naturally couldn't be bored and let people dig under the city wall on the second floor of the fortress, how much time would it take, like that, a month would not be enough to capture a fortress.

He had already made arrangements, but Andre didn't expect it, on the morning of the third day, at that time, the Ming army set up a position again to dig the city wall, but this time, the soldiers under the siege vehicle not only brought a pickaxe and shovel, but also brought the explosives used in the construction of the railway by the Ming Dynasty, the largest kind, the explosives with a thick thigh!

At noon on the third day, at noon, just as Andre was about to order a man-made meal, there was a loud bang, the cave mountain shook, and the entire No. 18 fortress shook a few times.

"Oops, it's dynamite." , Andrei ran back to the top of the tower in one breath, took out the binoculars and went down, bought cakes, the first floor of the fortress near the city wall is like a dog gnawing, there are gaps everywhere, and the Ming army is desperately cleaning up the gravel at the gaps!

This is a big trouble, if they are allowed to clean up the rubble, the siege vehicles covered with iron plates can not be pushed up from the gap, and in this way, the second and third floors will also be easily broken by them.

He hurriedly ordered: "Quick, order the soldiers on the second and third floors to aim and shoot to stop them from cleaning up." “

At this moment, the Ming artillery array remembered the terrible roar again, and the scattered bullets covered the second and third floors of the fortress like a dark cloud, and more than half of the Ming soldiers raised their rifles in the gap below, and shot at the outcropping Russian soldiers, and the Russian soldiers on the second and third floors were immediately pressed back.

With such a rapid response and such precise cooperation, the performance of the Ming army is simply a model of infantry and artillery coordinated combat, how can this fight with others!

Andrei could only reluctantly order: "Quick, order all the soldiers on the first floor to withdraw to the second floor, and the others pay attention to concealment." “

There were only two or three hundred uninjured soldiers left on the first floor, and the injured had already moved to the second and third floors, and before the Ming army could rush up, they ran up to the second floor, and the first floor was empty.

The Ming soldiers quickly cleaned up the gravel at the gap with the cooperation of artillery fire, and the siege vehicles were pushed up to the first floor platform one by one, and tens of thousands of Ming soldiers pushed the siege vehicles to search everywhere on the first floor, and after making sure that there was no danger, they pushed the siege vehicles to the second layer of the city wall.

Although it was not certain that there was no one on the side of the second-story city wall, before approaching the city wall, the Ming army first threw a wave of grenades, and then pushed the roof of the siege vehicle to the city wall, digging through, just like the first-floor offensive and defensive battle.

Andrei still has nothing to do, he doesn't dare to send soldiers close to the edge of the city wall to throw boulders, pour fire oil, that is purely to send food to the Ming army, although the Ming army's tactics of digging the city wall are not very clever, but under the existing circumstances, he just can't stop it.

He could only pray that Golovin would seize the opportunity and sneak attack, otherwise, sooner or later, this fortress would be dug up by the Ming army!
