He glanced at the Rouran army besieging the city, and then at the Ouchi guards behind him.

Zhao Rui suddenly had an idea in his mind.

There were a total of fifty people accompanying him, all of whom were elite soldiers selected from a million.

"The border towns are in crisis. We are all working for the emperor. We must not just watch the city fall into the hands of others!"

These imperial guards can be regarded as Murong Bing's personal soldiers and are loyal to her.

"Father-in-law, what do you want us to do?"

Zhao Rui nodded with satisfaction, and then pointed to the Populus euphratica forest not far away.

"Where you are, hang some tree branches on the horse's tail from the car, and then circle around on the sand behind the enemy. In short, make the noise as loud as possible."

These people also knew some art of war and immediately understood what Zhao Rui meant.

The accompanying captain of the guard left two people here to protect Zhao Rui, and led the remaining people straight to Populus euphratica forest.

Zhao Rui was now sure that these guards must have received secret orders from Murong Bing before they came, otherwise they would not still be looking at him at this time.

Not long after, dust began to rise behind the Rouran phalanx, and rapid drumming and shouting could be heard at the same time.

"Your Majesty has an order. Anyone who kills General Rouran will be rewarded with a reward of one thousand taels. Anyone who kills Rouran Chanyu will be rewarded with a reward of 10,000 taels and be granted the title of Marquis of ten thousand households!"

Even Zhao Rui could hear the earth-shattering shouts clearly.

It didn't take long for Rouran's military formation to fall into chaos.

With such a huge amount of sand suddenly appearing in the rear, tens of thousands of elite soldiers must have cut off their retreat.

Coupled with the powerful shouts of killing, the morale of the Rouran army was suddenly disturbed. Even the accompanying Huns cavalry were frightened out of their wits.

They had been ambushed by Shan Tianxiong a few days ago and lost 80,000 elite soldiers.

For a time, the battlefield became chaotic. In desperation, General Rouran could only order a retreat.

Zhao Rui breathed a sigh of relief and entered the border city through the side door with the two inner guards around him.

Shan Tianxiong was sitting in the lobby dragging his weak body, pointing at the map with his violently trembling palms, and issuing instructions intermittently.

His face was already livid, and black blood continued to seep from the bandaged area on his chest.

"General, the enemy has withdrawn!"

The sudden report made Shan Tianxiong's eyes widen.

He knew the situation in this city best. As long as the opponent attacked fiercely for an hour, he could break the city. Why did he withdraw his troops for no reason?

Just when he was confused, Zhao Rui quickly walked in with two imperial guards.

"Well, old general!"

Seeing Zhao Rui, Shan Tianxiong breathed a sigh of relief.

Hey! He had seen Zhao Rui's military talents when he was in Murong Bing's chamber.

Thinking about it, Zhao Rui must have used some method to repel the enemy.

"Father-in-law, you are finally here!"

As soon as he said these words, Shan Tianxiong's body went limp.

After suffering such serious injuries, being poisoned, and holding on to hold on to command on the battlefield, it's pretty good that he can hold on until now.

Zhao Rui hurriedly stepped forward to grab Shan Tianxiong's pulse and found that his physical condition was in a mess.

The poison in it should be a neurotoxin, which has spread all over the body at this moment. If it is not treated in time, I am afraid that I will die of shock.
