Chapter 556: The Underground Path

"Hahaha, cool!"

On the wall of Ningcheng, Qin Shan clapped his hands and laughed. Read М

Under the threat of the hot air balloon, there was a lot of chaos in the North City camp.

This was exactly what he expected.

After staring for a while, he went down the wall and prepared to go back to rest.

When passing by the gap in the wall, the soldiers were following his orders to set up more barricades within 200 meters of the gap.

The battle last night made him feel that there was no need to repair the gap.

The Beidi soldiers rushed in from the narrow gap and became targets for the musketeers.

If there were no rifled guns like before, they could only let the heavy infantry go forward and fight with the Beidi soldiers with swords.

In this way, facing the numerical advantage of the Beidi, Ningcheng was really in danger.

"But the ammunition we carry this time can't last long, General Mo, you must arrive in time." Qin Shan suddenly sighed again.

Just as he was about to leave, he remembered something and asked the general beside him: "How many people were killed or injured in Beidi this time?"

"General, there are more than 16,800 people." The general replied.

Beidi launched an attack from the four walls, and a lot of troops were deployed at one time.

So the casualties caused by their one-night battle exceeded those of Yanguan.

"What about us?"

"Two thousand and eight casualties." The general said again.

Qin Shan couldn't help but sigh.

This is a casualty ratio of nearly eight to one.

If it fell on the other armies of Dasong, they would almost be crazy with joy.

But for him, this is the normal casualty of the Wangfu's personal army.

"Try your best to treat the wounded." Qin Shan explained.

The proportion of wounded soldiers among these two thousand people is even greater.

If they can survive, the comparison of casualties between the two sides will be higher.

This time to Ningcheng, there are also medical officers accompanying them, and they brought a lot of Wangfu secret medicine.

This will save the lives of the soldiers.

After instructing these, Qin Shan went back to rest.

He ordered the soldiers to take turns to rest and prepare for the night battle.

Night fell.

The Beidi launched another attack, just like last night.

This time, the Beidi brought out the gunpowder barrels again, and three gaps were blown out of the Ningcheng city wall.

However, due to their experience, Qin Shan and Guan Tong quickly dispatched soldiers to the gaps and set up barricades.

For them, the walls of Ningcheng, like the chariots of the chariot camp, played the role of hindering the Beidi cavalry.

Even if the wall collapsed, it was like a high mound.

The cavalry could not charge straight in from outside the city.

As for the Beidi infantry, they were not afraid at all.

Under the dense formation of rifled soldiers, as many Beidi soldiers rushed in, they died.

What's more, the gap was very narrow, and the number of Beidi soldiers who rushed in at a time was limited.

At the gap, they had a complete advantage in manpower compared to the Beidi. After all, it was impossible for the Beidi to rush into the gap with thousands of people at once.

It was good enough to rush in hundreds at a time.

"Go ahead, blow up all the walls of Ningcheng if you can." Qin Shan sneered.

After observing, he found that the casualties of the soldiers on the wall were greater than those at the gap.

But he had to defend the wall.

After all, if the Beidi soldiers occupied the wall, their attack would change from point to line, and they could enter Ningcheng from anywhere, which would make it difficult to defend.

After five days of fighting, both sides were exhausted.

The royal army was exhausted because of the disparity in strength and could only deal with it.

The Beidi soldiers attacked at night and did not sleep well during the day.

On the sixth day, after counting the casualties, Mule Hongzhen's face was ashen.

In the battles of the past few days, they had lost 20% of their troops.

"Tiemuta, let the 50,000 troops of Jincheng come to support immediately."

Originally, he was worried that the Yanwang troops would take the opportunity to attack Jincheng.

So he left 50,000 people to deal with emergencies to prevent Jincheng from being lost.

But after so much time, Jincheng is safe and sound.

He thought, maybe he was redundant.

At present, both his troops and those under Gultu and others were very tired.

He needed this energetic army to launch a fatal attack on the Yan Wang troops in Ningcheng.

"Yes, father Khan." Temuta raised his eyebrows.

After so many days of stalemate, it was finally time to launch a surprise attack on the Yan Wang troops in Ningcheng.

Mule Hongzhen gave the order, then left the tent and looked at a location 300 meters away from Ningcheng.

There was an artillery fortification built with sandbags at that location.

This fortification had long been destroyed by the Yan Wang artillery in Ningcheng.

There was still a lot of straw inside.

But he knew that there was a hidden world under this damaged fortification.

Taking advantage of the night attack, he took the opportunity to send soldiers to dig tunnels under the fortifications and transport the excavated new soil to the camp to hide.

During the day, straw was used to cover the hole.

And in order to cover up this secret operation, he deliberately did not send soldiers in this direction.

Therefore, during night battles, the King of Yan rarely threw explosive shells at this location.

Even if he did, the sandbags would cover the soldiers digging the soil.

As the tunnels got deeper and farther, he was even less worried.

The soldiers of the King of Yan could not find the soldiers hiding in the tunnels.

"We can dig into Ningcheng in one day." Mulehong really narrowed his eyes.

The gaps in the city wall that were blown up in the past few days made him very disappointed.

Many Beidi soldiers died, but they could never break through these gaps.

And through the tunnels, a large number of soldiers could enter Ningcheng at night and kill the soldiers of the King of Yan by surprise.

"I also used this method when we were digging at Yanguan, but unfortunately when we dug to the base of the city wall, we hit the new wall of Yanguan. I don't know what the damn King of Yan was thinking. The new wall buried underground was so deep that our tunnel failed." Gurtu said.

When he encountered the new city wall, his soldiers tried to chisel the new city wall and continue digging into Yanguan.

But he didn't know why he was discovered by the soldiers of Yanguan.

The soldiers of Yanguan kept bombarding the ground with artillery.

His soldiers fled back in fear.

Zhao Xu would have laughed if he heard what Gurtu said.

In modern times, building construction technology is very mature.

When he built the outer wall of Yanguan, he also gave Zou Rong a lot of guidance.

Because the outer wall of Yanguan is very tall and made of concrete.

He deliberately asked Zou Rong to dig a five-meter-deep foundation. After all, if the foundation is dug, the city wall will easily collapse.

As for being discovered by the soldiers of Yanguan, it is also normal.

Concrete has good sound conduction performance.

If you are renovating in the same building, as long as you smash the concrete, the whole building can hear it.

The Beidi soldiers chiseled the base of the wall, and the Yanguan soldiers could not fail to notice it.

"Humph, Yanguan is Yanguan, Ningcheng is Ningcheng, the city walls here are incomparable." Mule Hongzhen gritted his teeth and turned back to the tent.

At noon the next day, many cavalry came from the north.

Mule Hongzhen immediately asked these soldiers to take a rest.

The next morning, the soldiers in the tunnel came to report.

The length of the tunnel was already 380 steps.

Nodding, Mule Hongzhen prepared to let the soldiers who came to fight in Ningcheng through the tunnel at night.

Just when he was proud, suddenly a cavalry came from the south, knelt on one knee in front of him and said, "Khan, it's bad, a Yan Wang soldier appeared on the south side."
