When Ruan Yanluo made the zuò smoke ball, he estimated the time and size of its burning, and it did not burn for a long time. Because if the smoke ball is too large or burns for too long, the sulfur dioxide in the air cannot be dispersed by the wind, and if the wind direction changes, the people in the valley will also suffer.

About the time I touched the tea, the smoke gradually dissipated, and all that remained of the smoke ball was a black mass that could not be seen in shape.

There was a hoarse and dry shouting outside, because of the edema of the respiratory tract, those people couldn't even scream, and with enough strength, they could only make the sound of Hehe.

The prince of Rongguo was escorted by a group of personal soldiers and ran away, avoiding the range of smoke, he looked at the open space in front of the valley gate, and he wanted to cry without tears.

He brought out an army of 30,000 people, but except for these people who ran away with him, there were some people who were quick and quick-witted, and almost all of them were shrouded in smoke.

Those people are lying on the ground now, some of them are motionless, and the rest are rolling and howling, and even if they are alive, they are not far from death.

Those dead people with hideous expressions, or those who are about to die, constitute a terrible hell on earth.

The prince of Rongguo gathered the people and counted them, and found that there were less than 10,000 people who could stand.

His nearly 20,000 men and horses were inexplicably stacked in front of a small valley gate.

At this time, Ruan Yanluo watched the smoke dissipate, there was no danger, and Yan Ming also recruited people back.

Although the sulfur smoke solved most of the Rong soldiers, after all, the other side still had 10,000 people, twice as many as them, and the city wall was already crumbling, if the prince of Rong was desperate to fight to the death, it would not be so easy to solve.

"Listen to the people in the city!" The crown prince pointed at the city tower and shouted in his throat: "If this prince doesn't raze this place to the ground today, and doesn't chop you all into meat paste, he will be in vain for His Royal Highness the eldest prince of my Rong country!" ”

After roaring, he waved his hand and roared again: "Siege!" ”

At this time, after the dawn of time, the direction of the wind had changed, and it was no longer possible for Ruan Yanluo to use the terrible thing just now against them, and the prince's siege was fearless and hoarse.

And the soldiers of Rong State had just seen so many comrades fall in front of them, and they had already been aroused by the grief and indignation in their hearts.

Fighting is fighting, but no such despicable means are used.

Therefore, as soon as the prince gave the order, everyone rushed to the city wall with red eyes and desperate eyes.

"Defend the city!" Seeing this, Yan Qing immediately shouted.

This time the defense of the city will not be easy, and it will be even more difficult than the previous ones.

Because now the soldiers of Rongguo are mourning soldiers, and the mourning soldiers have a momentum that is not afraid of death, and they have used up all the materials to defend the city, and now all they have is the knife in their hands, only hand-to-hand combat!

There were no rolling stones and wood, no oil and not even much of a reserve of bows and arrows, and the Rong people attacked along the ladder with little effort.

But firstly, the area of the city wall of Chang'an Valley is small, and secondly, the cloud ladder of the Rong Kingdom has been destroyed a lot after a few charges, and there are not a few left, and the Changfeng army can guard a gap with nearly one or two hundred people, and for a while, I am not afraid that they will attack the city.

But in the same way, the Rong people's fierce fighting style of not fearing death, as well as their numerical advantage, also dragged the Changfeng army firmly on the city wall, and half of them didn't want to be idle.

At this moment, the sky suddenly lit up with a dazzling light of arrows, Ruan Yanluo hurriedly looked along the place where the arrows sounded, and saw that it was the prince who sent it, and the method of launching it was obviously a certain way for them to transmit the signal.

"Who is he signaling? Could it be that the maze outside is not sealed, and there are still people who can come in? Or is there something else? ”

Ruan Yanluo frowned, and he didn't know if he was talking to himself, or if he was talking to Nangong Ling next to him.

Nangong Ling also narrowed his eyes slightly, although the prince of Rongguo looked a little reckless, but when he was fighting, his methods were very accurate, and he was not a brainless.

If there was no answerer, he would not have been able to convulsive and shoot arrows into the sky.

"Yan Yue!" Ruan Yanluo shouted.

"In!" Yan Yue was not far away, he heard Ruan Yanluo's shout and agreed loudly, he saw the scene outside, if he was still dissatisfied with Ruan Yanluo before, then after this scene, he was also completely convinced.

If it weren't for Ruan Yanluo's presence today, Changfeng Army would probably have been removed from the world.

"Are you sure you've changed the structure of the maze?"

"Sure! No one is guaranteed to come in from the outside! ”

"Yan Qing!" Ruan Yanluo shouted again.

"In!"

"Are you sure there is only one exit from Chang'an Valley, and there is no other exit?"

The secret road is not counted, the secret road is the same as the mountain gap that Ruan Yanluo walked on, it is naturally formed by the geological movement inside the mountain, and there are forks in it, Shen Hongyan also inadvertently walked to the city of Fengzhou back then, and then forcibly drew a picture with his memory against the sky.

When she discovered this place, she was already in the late stage of the world's conquest, and she also vaguely felt the emperor's suspicion. She kept this road, originally thinking that if the emperor really wanted to attack her and Master Ruan, she and Master Ruan could enter Chang'an Valley from this road unconsciously.

After all, Fengzhou City and Chang'an Valley are quite a long distance, and there is still a Yunya Pass in between, no one could have imagined that there would be such a road.

This road is in the territory of Tianyao, and the purpose of the prince of Rongguo's trip is to know how it goes, so even if he really has someone to answer, it can't be this road.

"My subordinates are sure that there is only one way in Chang'an Valley!" While Ruan Yanluo was thinking, Yan Qing also shouted loudly over there: "This place is surrounded by mountains on three sides, and the back is above the snow line, all of them are ice cliffs, it is impossible for anyone to come in from other places." ”

Yan Qing said that Ruan Yanluo knew that she had also gone to see it in person, and it was impossible for someone to ...... from somewhere else

Wait, what did Yan Qing say just now?

Ice cliffs?

A series of fragmentary images suddenly flashed through Ruan Yanluo's mind.

When she and Nangong Ling went to the back of the valley just now, they saw an eagle, and the eagle was very shy and hid when they saw them.

The cliff behind the valley is only a few dozen feet from the ground, and people with good kung fu can jump directly from it.

There are also small pieces of iron that look strange and strange with spikes stitched together in all directions.

Ruan Yanluo suddenly broke out in a cold sweat on his forehead, and he was terrified.

It's not that Chang'an Valley has no way to get in, it's just that no one dares to use that method.

The people of Rong are crazy, in order to attack Tianyao, they can even think of this method, do they want to die?

"Come on two hundreds, follow me!" Ruan Yanluo shouted.

"I'll go with you." Nangong Ling landed beside Ruan Yanluo without hesitation.
