Night.

Outside the pass, there was silence.

On the tower of Yumen Pass, the lights were bright, and the soldiers in charge of the rotation raised their vigilance to the highest level, and kept looking outside, for fear that the people from the Western Regions outside the city would come to attack at this time.

However, the lights above do not illuminate the darkness below.

Dozens of masters of the Taiping Dao quietly approached in the darkness and came to the bottom of the city tower, and the soldiers on duty above could not see the movement in the darkness below at all.

The offensive and defensive battles have been going on for so long, and the people of the Western Regions have never tried to attack at night, so their vigilance at night will be relatively relaxed, although the vigilance is still very high, but no one would have thought that the enemy has come to the pass.

The masters of Taiping Dao lurked below, they took out one, similar to the Luoyang shovel, and carefully dug a hole below, at this time, the wind outside the pass, blowing towards the Yumen Pass, the wind whistling, blowing the fire on the city tower swaying, able to cover the movement below.

This is also the reason why Zhang Min is ready to do it tonight.

He was sure that the wind would blow tonight, and the sound of the wind in the dark would drown out a lot of sounds.

The Luoyang shovel dug into the compacted soil of the city wall, and the movement brought by it was not very large.

After a short time, they dug out small holes that went deep into the city wall of the pass.

"That's it!"

A master of Taiping Dao said in a low voice.

The rest of the people hurriedly started to stuff all those explosives into the hole, only on the outside, leaving a long enough lead, this operation is called directional blasting, as long as it is used properly, it is not a problem to blow up the city tower of Yumen Pass.

"Ignition, withdrawal!"

Another master whispered.

The fuse was quickly ignited.

They turned and ran, fleeing back to the camp in the Western Regions.

Meanwhile.

The soldiers on duty on the city tower suddenly saw that there seemed to be a fire below, they quickly looked down, only to see a line of fire, which was spreading towards the city tower, and was about to burn out, although it was in the dark, but according to their cognition, they could still see at a glance that it was the light of the explosive fuse burning.

"Not good, the enemy is coming!"

"Beat the drums of war!"

A soldier shouted.

The other soldiers also looked out, their faces changed greatly, they did not think that explosives could blow up the pass, the first thing to do was not to escape, but to sound the war drum to warn.

However, before the drum was beaten, a terrifying explosion appeared under the tower, and the entire city wall shook, cracks appeared, and the impact of the explosion penetrated the layers of masonry and extended to the soldiers above.

Rumble......

The city tower of Yumen Pass was bombed and collapsed, and the soldiers on it were either blown away, or with the collapse, they fell from side to side and were crushed under the masonry and mud.

The ground is also shaking.

The sound of the explosion, which appeared in the darkness of the night, woke everyone in the camp behind the pass.

Zhao Yun and Ma Chao hurriedly walked out to take a look, and just saw the scene of the collapse of the city tower, their faces suddenly changed greatly, and a feeling of uneasiness came to them, those people from the Western Regions really had tricks, they actually had explosives, or explosives that were not weak.

"Cavalry mount and wait for orders!"

"All the infantry are out of the camp!"

"Roll out the artillery, and the whole army is ready to fight!"

Zhao Yun reacted the fastest, shouting in a roaring voice.

All the soldiers who were frightened by the explosion came to their senses at this time and all mobilized, Ma Chao and they hurriedly prepared all kinds of artillery, aiming the muzzles at the completely collapsed city tower, Tian Yu had already led the Xuanjia spirit cavalry out of the formation, ready to rush to the enemy at any time.

Outside the customs.

Thorge and Gui Sumi, they didn't rest.

The entire army of the Western Regions Alliance Army has not rested at this time, just waiting for Zhang Min to say that it can break through the Yumen Pass tonight.

Seeing the city tower of Yumen Pass, which was so easily blown up and collapsed, they suddenly became excited, and the soldiers of the Western Regions, who had been tackling the key problems for so long, saw the light in front of their eyes, and their fighting spirit was agitated, and with an order, they all rushed to Yumen Pass.

After fighting for so long, I finally broke the level.

As long as they enter it, they think that they can occupy the rich land of the Han Dynasty and live a rich life.

"Kill!"

Those soldiers from the Western Regions let out a burst of shouting and killing, and rushed to the front.

When Zhang Min saw this, he couldn't help but sigh: "This kind of explosives, as well as directional blasting, is really powerful!" ”

Watching Suo Ge and them lead the troops to kill Yumen Pass, Zhang Min's task was completed, he didn't stay, he took the people around him, turned around and left here, and then even if Gui Xu Mi and others occupied Dunhuang, they wouldn't be able to hold it for long.

As long as Yang Zhao arrives, the Western Regions Alliance will undoubtedly be defeated, and they will still be driven out.

They are too peaceful, as long as they can withdraw in time.

The Western Regions Coalition Army quickly slaughtered Xiangyumen Pass.

The collapsed pass is in ruins.

They cut through the ruins and fought their way into it like wolves and tigers.

"Hit!"

Artillery and other things, as soon as they were prepared, the enemy came, and Ma Chao hurriedly ordered people to do it.

Artillery and mortars were fired out at the same time.

The sound of an explosion, echoing in the night sky.

But the people of the Western Regions did not seem to be afraid of death, even if they saw that their companions in front of them were killed, they still rushed in regardless of the fire, braving the artillery fire.

"Meng Qi, there are no more shells."

Pound came over and said anxiously: "Our shells can only attack one more round." ”

"What?"

Ma is in a hurry.

Not so long ago, they were running out of shells.

It took a fight during the day, and it consumed a lot, and now the remaining support will not last long and will soon be used up.

"Finish the last round of shells and hold back the enemy's charge."

"The infantry retreats first, and the cavalry breaks behind."

"How?"

Tian Yu said.

Ma Chao could only agree: "Okay, call me!" ”

Rumble......

After the shells were fired, the infantry packed up their things and retreated directly to Dunhuang.

The gap between the forces of the two sides is too large, the enemy's forces are too many, this charge, there will be at least 100,000 enemies surging in as the vanguard, they do not retreat, it will be difficult to fight, basically there is no possibility of winning.

The bombs suppressed the enemy for a moment, and the infantry quickly retreated.

"Kill!"

Zhao Yun shouted.

The hoplites rushed out first.

More than 10,000 hoplite cavalry, divided into ten squads, followed back and forth, charged at the soldiers of the Western Regions who were walking in the front, divided the battlefield, charged and killed a large number of enemies, and then retreated to open the distance.

The Xuanjia Elite Cavalry followed the hoplite cavalry and rushed forward to shoot a round.

Bullets and arrows fly towards the enemy.

Immediately knocked down a piece.

The light and heavy cavalry fought alternately, intercepting and killing the soldiers of the Western Regions in front, so that the front army of the Western Regions Alliance did not dare to move forward.

However, at this time, the soldiers of the Western Regions, under the command of the generals, changed their offensive strategy, and used strong bows and crossbows to resist the cavalry, while countless soldiers raised their shields and poured out forward, wanting to outflank the cavalry from all directions.

They wanted to encircle, trap the cavalry in it, and then drag the cavalry down.

"Retreat!"

Zhao Yun saw through the enemy's thoughts, and first killed a bloody path and helped the Xuanjia Elite Cavalry to kill out.

After the Xuanjia elite cavalry left the enemy's interception, Tian Yu ordered to shoot at a distance to the rear to cover the heavy cavalry to kill, and the cooperation of the two sides was tacit.
