Mythical Qin: I, Gao Yao, will never be a eunuch!

As the camp gate was successfully broken open, the black-armored soldiers who had been waiting in full battle array rushed in like a tidal wave and rushed directly into the camp of the imperial army. Among them, Ying Bu led the way, riding a tall and mighty black warhorse, holding a giant spear, looking as majestic as a god of war. Wherever he went, the enemies fell to the ground one after another, and no one could stop his advance.

The hastily organized defense line of the imperial army was simply vulnerable to the fierce attack of Ying Bu and the Black Armor Army. In an instant, this supposedly indestructible defense line collapsed, the soldiers fled in all directions, and the scene was in chaos.

The key reason for such a one-sided situation is that cavalry has a natural restraining advantage over infantry. When those fierce cavalry rushed into the camp, facing the soldiers whose formations had long been in disarray, they showed unparalleled lethality. This scene is like a hungry tiger suddenly breaking into an unsuspecting flock of sheep, killing them wantonly, which is very frightening.

For a moment, shouts of killing rose and fell, resounding through the sky. The roar of "Kill! Kill!" resounded throughout the battlefield, interweaving with the "puff, puff, puff..." sounds made when weapons collided, forming a thrilling symphony of death.

At this time, the mysterious Yi Xiaochuan had already killed several black-armored soldiers on his warhorse. When he looked up again, he saw that the entire camp was almost full of black-armored soldiers charging and killing. The imperial army did not even have a chance to rebuild its defense line.

"Quick, immediately send someone to notify the vanguard to quickly return to support and withdraw from the camp. Let the shield soldiers take over and don't let the enemy rush out of the camp. Quick!"

At this moment, the mysterious Yi Xiaochuan hesitated for a moment, but soon began to issue orders without hesitation. He had experienced situations like this, or even more severe and severe situations, countless times in his thousands of years of life. Therefore, facing the chaotic situation before him, the mysterious Yi Xiaochuan did not feel panic at all, but was unusually calm and composed.

He made a prompt decision, quickly adjusted the battle plan, and decisively ordered his soldiers to stop fighting with the Southern Border Army in the camp. At this moment, the entire camp was in a state of extreme chaos. If measures were not taken in time, the consequences would be disastrous. Therefore, the mysterious Yi Xiaochuan knew that the most urgent task at the moment was to withdraw all the soldiers from the camp as soon as possible in order to reorganize the army.

It is not easy to achieve this goal smoothly. After all, the enemy is coming with great momentum. If you retreat directly, you will inevitably be pursued and encircled by the enemy. After careful consideration, the mysterious Yi Xiaochuan made a difficult but wise decision-abandon some soldiers. These selected soldiers will bravely stay and serve as cannon fodder to delay the advance of the Southern Border Army, buying enough time for the large army to build a solid line of defense. Although this means that they may face great danger or even sacrifice their lives, only in this way can the battle situation be stabilized at the fastest speed and ensure the smooth implementation of the overall strategic deployment.

After receiving the precise and decisive command and order from the mysterious Yi Xiaochuan, the well-trained and well-equipped imperial army instantly exploded with amazing fighting power like a ignited gunpowder barrel. They abandoned all the heavy baggage without hesitation and rushed in the same direction like a surging torrent.

At the same time, some shield soldiers were quickly dispatched to form a solid defense line, trying to stop the aggressive and unstoppable charging black armored army. However, everyone knew that facing such a powerful enemy, these shield soldiers were just like an egg hitting a stone, and the so-called "stopping" was more of a tragic sacrifice.

After all, under the indestructible cavalry of the Black Armored Army, both the ordinary infantry and the shield-bearing soldiers seemed so fragile and powerless. But even so, these shield soldiers still stood firm and used their flesh and blood to delay the Black Armored Army's advance as much as possible, buying precious time for their main force to break through.

The mysterious Yi Xiaochuan, on the other hand, led the way, leaping on his horse and whipping his whip, and rushed directly outside the camp. Sitting firmly on the horseback, waving the command flag in his hand, he kept issuing various instructions. Following his command, a large number of soldiers quickly took action, drawing their bows and arrows, aiming at the black-armored army in the camp. At this time, the accuracy of the shooting was no longer important. The only goal was to let the arrows pour down like raindrops, causing certain interference and casualties to the enemy. For a moment, only the sound of bowstrings resounded through the sky, and dense arrows cut through the sky, shooting towards the black-armored army camp with a sharp sound of wind.

Just when the mysterious Yi Xiaochuan had just led his soldiers to gain a foothold and successfully organized a fierce round of archery attacks, suddenly, a deafening shout of killing came from the other end of the road.

Then, a large group of aggressive southern troops came like a tide. They were all wearing shining helmets and armor, holding sharp blades, and rushed towards the imperial army with murderous intent.

The scene in front of him once again shocked the mysterious Yi Xiaochuan! He originally thought that this was just a surprise attack by the Black Armor Army. Looking around, the number of enemy troops seemed to be only more than 5,000 people. However, they had 30,000 people! Although they were a little flustered at the beginning because of the sudden incident, as long as they could quickly reorganize the army and fight, they should still have time to make an effective counterattack. Of course, losses are inevitable, but it is not a complete defeat.

But who would have thought that things were far from that simple. At this moment, even the infantry of the Southern Border Army appeared on the battlefield. A rough estimate of their number was at least more than 10,000! Seeing this, Yi Xiaochuan realized in his heart that there was no chance of winning this battle. Not to mention defensive counterattacks, even holding on and waiting for the central army to come back for assistance was a foolish dream.

More urgently, Yi Xiaochuan had a crucial problem to solve: how to retreat safely? Should he retreat towards Heilongkou and join the main force? Or should he just break camp and flee?

If they retreated directly, it would be equivalent to abandoning the army in Black Dragon Mouth. If the Southern Border Army occupied the exit of Black Dragon Mouth at that time, with the advantage of terrain, it would be almost difficult for the tens of thousands of troops in Black Dragon Mouth to break out.
