Ye Yu, who was overjoyed, then twisted the stone ring three times to the left and then two times to the right according to the logo of the parchment roll.

However, just as Ye Yu had just finished twisting the stone ring, he heard a violent sound at the foot of the nearby mountain.

Click!

At the same time as there was a sound at the base of the mountain, the sand on the ground shook and trembled violently.

Then a strange scene happened, and I saw that the pile of sand that had just risen suddenly caved down, and the sand continued to sink in like flowing water, until all the sand on the nearby ground collapsed into it.

Regarding this anomaly like the mouth of a demon, Ye Yu calmly came to the front to take a look.

"It's ......"

"Is this a whirlpool of quicksand?"

"Or......"

Speculation is speculation after all, but Ye Yu stared at the huge pit that he had fallen into, and then said in a deep voice: "Lone wolf, you follow me in to find out!" ”

"Yes!"

As soon as he finished speaking, without the slightest hesitation, he directly picked up the mud and sand and entered the oblique pit......

Not long after entering the pit, Ye Yu and the lone wolf returned to the surface safely.

"Brother Ye, are you okay?"

When Ye Yu returned to the ground, Wu Qingyin couldn't help but throw herself into her arms, full of worry beyond ⊙words.

Seeing this, Wu Yuechan was secretly jealous, and immediately raised the topic, pretending to change and ask: "Your Highness, here is ......?"

"Fang has already investigated, this is the entrance to the Red City Castle, and the phenomenon of the collapse of the sediment is because the stone door that is buried underground is opened, and the sediment will be automatically introduced into it!"

Hearing this news, everyone was pleasantly surprised!

"Yuechan, you immediately dispatch people to dig up this entrance, there is not only plenty of space in it, but also a water source that our army urgently needs!"

"Water, that's great!"

When you hear the word 'water', it's far more precious than gold.

When Wu Yuechan passed the news to the army, all the Song troops began to cheer. And the soldiers who were selected to dig the entrance were even more desperate to dig hard.

The strength of the crowd is great, even if it is two meters of deep sand, it is not a problem in front of everyone, and in less than half an hour, the original collapse has opened up a wide passage.

The sediment deposits at a depth of two meters conceal the huge cave that was originally carved out of the mountain wall.

At first, Ye Yu felt that this bald stone mountain located in the stone forest was inconspicuous, but when he entered along the entrance, he realized that there was something inside this bald stone mountain.

Ye Yu can now assert that this mountain must have been a majestic mountain back then, otherwise it would not have opened up a mountainside passage that was enough to accommodate a thousand people in this mountain.

And this passage leads directly to the underground castle not far away, which is the long-rumored Red City Castle.

Perhaps it is the geographical environment, or the castle built of red mud and sand is too strong, or the magic of nature, so that this castle, which has been covered by wind and sand for many years, still maintains its original appearance under the yellow sand.

At the same time, after preliminary estimates, the Hongcheng Castle and the winding passages along the way can form a temporary living space, which can roughly hide 10,000 people.

Of course, these are not the most important, but the most important thing is that in the Red Dust Castle, there is a sweet and cool water source.

The desert has covered the buildings and the landscape, but the water source in the former Hongcheng Castle is still preserved in the form of an underground undercurrent.

In fact, there is a water source under the sand in every part of the desert, and the difference is the thickness of this water source and the surface.

Some of them are a few feet thick, and there are traces of water, so a few weeds in the desert will grow. And some of them go down ten meters and there is no sign of water sources, so it is destined that there will be no life on the surface.

Although the water source in the Red City Castle is also blocked by sand and soil, in this situation with a goal, it is no longer a big problem to get water.

The problem of water was solved, but the ensuing problem of food and grass once again became a major problem for the army.

In the night wind, Ye Yu sat on a bluestone in the stone forest and asked Xin Qiji beside him, "How long can the soldiers in the army carry food?" ”

"The last general has returned the food to the generals and lieutenant generals, and then distributed the food uniformly, but it is ......"

"Say!"

"Three-Day ......"

Listening to the words without confidence, Ye Yu shook his head helplessly and said, "Jiaxuan, do you know that you are untruthful, and you have also violated military discipline?" ”

“……”

"Can it last for a day, or even start running out of food?"

"The last general is ashamed that he failed to do a good job in logistics deployment, so that the army has now run out of rations, and if there is no more backup food and grass supply, I am afraid that it will ...... I'm afraid ......"

Xin Qiji knelt on one knee in shame, not daring to look up at Ye Yu.

"This matter has nothing to do with you, you don't have to blame yourself, this king is the commander of this army, and his responsibility should also be borne by this king!"

"Your Highness......"

Ye Yu waved his hand to show that there was no need to say more, and then said to himself: "Counting the time, it should be almost now, and now this king hopes that the Jin Liao army can come here!" ”

At this moment, I suddenly heard a report from Tanmalay, saying that the Jinliao coalition army was encircling and advancing here layer by layer, and now it is not a hundred miles away from here.

Hearing this, Xin Qiji's expression was solemn and uneasy.

On the other hand, Ye Yu was excited, and sneered: "It's really timely, this king is worried that you won't be able to arrive in time!" ”

It was night, and Xiao Hei spread his wings under the moon, and flew directly over the entire desert, flying in the direction where it was supposed to go......

Jiangnan, Lin'an!

At the beginning of Ye Yubing's two-way northern expedition to Western Xia, the people of the entire Jiangnan government and the opposition were always paying attention to the movements.

When they learned that Ye Yu led an army of only 60,000 and easily conquered 36 cities in a row in just over a month, such miraculous achievements were directly praised by the literati in Jiangnan.

This can be said to be Ye Yu's third most brilliant record since he took charge of the military power.

Whether it was the annihilation of 200,000 Western Xia soldiers or the return of Western Liao to the border, these were just bitter achievements in self-defense.

And the thirty-six cities of the enemy country are very different from the previous nature, because this is a great contribution to the expansion of territory!

For a time, Ye Yu's status in the hearts of the Song people continued to rise, and this height has far surpassed the crown prince of the current dynasty, and even surpassed the emperor Zhao Yan of the current dynasty.

This made Zhao Kai, the crown prince who lived in the East Palace, very uneasy, but fame is not something that can be accumulated overnight.

He knew that every time Ye Yu made a military exploit, it was equivalent to taking a step closer to him, and maybe in the end he would have no way to retreat.

And just when he was hesitant and helpless, he suddenly came to the border pass Jinliao coalition army military situation.

After seeing the military emergency report, which briefly described Ye Yu's experience of being trapped in the Northern Desert by 200,000 coalition troops, Zhao Kai stood in front of the window with a complicated expression, and the long silence was exchanged for a final sigh.

Because in the face of this situation, he didn't know whether he was happy or worried......
