Seeing that the barbarians were about to rush to the city wall, Hu Bugui involuntarily clenched the big knife on his waist.

"Two professors?" he turned his head to look in the direction of Professor Luo and the others.

And so on. Professor Luo spat out a word expressionlessly, but his eyes were fixed on the huge golden phoenix in the night sky.

This is......?

Hu Bugui squinted slightly, and also looked up.

With the movement of this commander, the soldiers of the empire also looked up.

At this moment, in the huge Qingzhou City, no one noticed the slow approach of the barbarians below......

Soon, the barbarians below also noticed the anomaly above the city walls.

At first, the crowd didn't notice. Until, the masked general who rushed to the front suddenly screamed, turned around sharply regardless of it, rode the war horse under him, and suddenly rushed into the distance.

What's going on?

Before everyone could react, they saw that the phoenix in the sky suddenly opened its mouth......

The next moment, a huge wave of white fire suddenly fell from the sky!

The white flames, menacing, were terrifying to the extreme, engulfing everything on the ground in an instant!

And all the barbarians who were stained with the flames barely had time to scream, they turned into ashes and disappeared into the world!

This scene, in the eyes of everyone on the city wall, was tragic and silent!

Even an old general like Hu Bugui, who was accustomed to seeing life and death, couldn't help but purse his lips and swallow his saliva......

In the distance, the barbarian people who had not yet been swept by the flames watched this scene that was terrifying to the extreme, but they seemed to be stupid, and everyone just opened their eyes wide and knelt on the ground.

It wasn't until a moment later that someone screamed.

The terrible and frightened screams woke everyone up.

Countless barbarians scrambled to get up from the ground, and all of them had terrified expressions on their faces, and fled as if they were desperate.

Soon, there was no one under Qingzhou City, only the white flames in the sky.

On the city wall, everyone was stunned, and even more, a hint of happiness flashed in their eyes for the rest of their lives.

In the distance, the barbarians who had fled in all directions occasionally glanced back, and they screamed in more and more horror.

At this moment, the huge phoenix in the night flapped its wings again......

This time, countless people fell to their knees.

Even Hu Bugui is no exception.

Tianwei is so!

The people who had just witnessed all this knelt down with great reverence against the white flames under the city walls.

Under the cover of night, the huge golden fire phoenix suddenly let out a long roar.

So, in the midst of everyone's stunned, the white flames on the ground suddenly flew back into the sky under the sweep of the night wind......

This scene made everyone extremely fascinated and shocked!

Then, the phoenix suddenly lowered its head and glanced at everyone coldly, and slowly closed its eyes.

The white light in the night gradually disappeared.

The figure of the huge golden fire phoenix gradually melted into nothingness.

After half a ring......

The night breeze blew, and the night was dark and silent, and it seemed that everything had returned to calm.

Except for ...... The look of shock in the eyes of the world and the palpitations in the hearts that have been difficult to calm for a long time!

......

The news of Feng Lin's human world and the barbarians' withdrawal spread throughout the continent at the fastest speed!

No one knows where that phoenix came from or where it went!

However, the news that it once appeared was enough to make the whole world crazy.

More and more cultivators frantically flocked to the northern frontier, bent on chasing the traces of the divine beasts......

What no one knew was that a girl in white left Qingzhou City leisurely on a small donkey at this time.

Along with the girl, there was also Professor Luo from Qingyi College.

Under the continuous green hills, when passing by the stream and lake, the girl turned over and got off the donkey, sat on a boulder beside the stream very leisurely, and looked up into the distance.

Behind her, Professor Luo frowned slightly.

"Susu, don't think too much. He said, looking up at the girl's line of sight.

Is that...... The direction of the capital!

An Lingsu sighed.

She didn't want to think too much about it, she just ...... I don't want to.

"Teacher," An Lingsu said, "You say, why did the emperor dare to let the iron cavalry full of people enter the pass? Isn't he worried that the iron cavalry of the barbarians will go all the way south and attack his capital after cleaning up the government soldiers in the hands of those great families?"

This point, An Lingsu has never figured it out.

Could it be that just to weaken the power of those big families, the emperor can even press down the dragon chair under him as a bet?

Isn't he afraid that the barbarians will even serve him as an emperor?

Professor Luo sighed.

"Su Su, what the emperor dares to do, he naturally has his reliance. He said expressionlessly, "Yun Clan, as a royal family...... Ben is one of the oldest surnames on the continent. ...... year Empress Zhang Huang also once said that the Yun clan still has a big secret in that imperial city......"

"What's the secret?" An Lingsu asked, looking back.

Now, Father An and Aunt An are in that capital, and if she wants to save the second elder, she has to think more.

After all, as far as she knew now, His Majesty the Emperor who sat on the dragon chair really didn't look like a good person!

"I don't know. Professor Luo shook his head and said slowly, "Over the years, the academy has also been thinking about this issue. Lao Chen and the others had analyzed that the secret in the imperial city was probably related to the power of the Yun clan's bloodline, or it was related to the former ......"

What was ever?

Professor Luo said this, as if he remembered something, and suddenly swallowed the words that followed.

An Lingsu frowned slightly.

The Yun clan has the power of the bloodline, she once heard Yun Ji say.

It's just that Yun Zhang, who was still Zhu Yuncheng at that time, just said that the men of their Yun clan seemed to have more strength than others, and when they practiced, they would produce strong power......

As for the rest, Yun Ji really didn't elaborate.

Of course, An Lingsu at that time was just a little curious, and this was Yun Ji's privacy, so she was not embarrassed to ask more.

But for now......

The girl's brow furrowed more and more.

After a moment's effort, Professor Luo also came back to his senses.

"Okay, Su Su, that secret in the capital should have been known back then. And...... Several of us old things also suspected that it was because we knew that secret that we would leave that imperial city at a young age. He said. "So, when you enter the capital in the future, you should be able to know that secret. ”

After all, she's so similar to Gentle!

An Lingsu nodded slightly, temporarily suppressed the matter from the bottom of his heart, and turned to ask about another matter.

"Teacher, the time agreed with Professor Zhang and them is almost up, right? I don't know how Zhang Ping and the others are doing?"
