Hua Yulang knew why the crown prince was so anxious. The army was indeed inspired by the loss of grain and grass supplies, but the premise of all this was that the soldiers were not hungry. You should know that it was very uncomfortable to be hungry, especially after fighting for nearly one night, the sun would rise in a few hours, The last meal of the army was yesterday morning.

If the dungeons can be conquered before the morning, the food hoarded by the enemies in the dungeons can solve the problem. However, if they can't be conquered, once it's dawn, the soldiers will lose their desire to fight because of fatigue and hunger. At that time, it will be really over, so not only Taizi is worried, but also Hua Yulang is very worried.

After receiving the order, Hua Yulang took several powerful generals, Dijia sect and two sect leaders of Changsheng sect to check the ground in the canyon to see if a channel could be dug up, but the people were depressed. It seems that the ground of the whole canyon has been specially reinforced and there is a layer of solid stone slab on the surface, Under the stone slab is a rammed earth layer made of special mixture mixed with loess paper. I don't know what formula people in the underground city use to make this rammed earth. The whole soil layer is harder than the stone slab on the surface. Hua Yulang asked people to dig it with a shovel. The result is like digging an iron block. If you want to dig through here, don't think about it for ten days and a half months!

But where do they have ten days and a half months? The prince's death order is to attack the dungeon before dawn at the latest. Now the night is over half, and there are less than four hours left from dawn. It's a dream to dig a channel into the dungeon in just four hours!

It is impossible to dig through the soil layer. Hua Yulang can only think of other ways. He has asked people to try to see if they can break the dragon stone. He also tested whether they can dig obliquely from outside the canyon, but in the end, it has never been successful. The design of the whole Dungeon seems to be specially strengthened to prevent invasion, No matter from any angle, any position, trying any method is useless!

Looking at the fish belly gradually exposed in the sky, Hua Yulang is going crazy. These rebels hide underground like turtles. They can't get in. The momentum of the army has begun to weaken. What should he do to let the army enter the dungeon?

Just when Hua Yulang was frowning, a soldier suddenly told Hua Yulang that he had found very soft soil under some stone slabs in the middle of the canyon. It was very easy to dig. The engineers had dug about 10 meters underground and even felt the change of the soil layer. It was estimated that it would be dug up soon!

Hua Yulang was overjoyed to hear the news. At the same time, he suddenly remembered that the people of Xiangcheng who had caught him before told him that there had been an earthquake in the canyon some time ago, and there were many cracks on the ground. A lot of black smoke came out from the cracks, resulting in the withering of thousands of acres of saliva grass overnight. Let alone what those black smoke were, The cracks on the ground must lead to the underground, that is to say, engineers should dig into those temporarily filled cracks. As long as these cracks can lead to the underground, everything will be solved!

In order to verify his guess, Hua Yulang rushed to the scene, and when he arrived, the soil layer had been excavated. Several huge cracks more than ten meters long and two or three meters wide appeared in front of him. The bottom layer of these cracks was filled with wood and covered with soil. It was really difficult to identify after paving stone slabs, If the soldiers hadn't inadvertently found out here, the army would be really helpless!

After the soldiers removed the board, Hua Yulang leaned over and looked below. There should be a huge space under the crack, because he could feel the air blowing out from the crack, and a pungent smell came out with the air.

Hua Yulang took a torch from the soldiers around him, and then directly threw it down the ground seam. The torch fell into a free fall and fell a deep distance. When the torch fell to the bottom, the light on the torch had become a small bright spot.

Judging from the falling speed of the torch and the distance from the visual flame, these cracks should be about 70 meters from the bottom. It's hard to judge how big the space below is, but it's definitely not small.

To be on the safe side, Hua Yulang decided to take several experts down to check. If there is really no danger below, he will let the army down.

After the decision was made, Hua Yulang tied a rope with a length of 100 meters to a big tree not far from the crack, and then took the lead in sliding down the rope. Ten soldiers and five magic star level masters of dijiamen followed him!

As he kept falling down the rope, Hua Yulang felt that the pungent and slightly fishy smell in the air was getting stronger and stronger. He was dizzy when he smelled it. It seemed that this smell would have an impact on the human body. Aware of these, Hua Yulang shouted to the people who followed him down, reminding them to keep their breath as much as possible, and then went down the rope to the bottom!

The down-to-earth feeling made Hua Yulang exhale. Then Hua Yulang picked up the burning torch on the ground and shone around.

The area of this hole is not small. At least it is impossible to see how big it is by the brightness of the torch. In the light of the fire, Hua Yulang saw that there are many wooden barrels around. These wooden barrels are densely placed on the ground. Most of them are sealed, as if they are preserving something. Out of curiosity, Hua Yulang came to one of the wooden barrels, He raised the torch and studied the barrel carefully, but there was no sign and handwriting on the barrel. It was impossible to know what it contained!

He raised his hand and pushed the bucket. Hua Yulang heard a sound of water shaking in the bucket. Then Hua Yulang frowned and said to himself, "what's in it? Water? Is this the warehouse where the rebels store water?"

Just when Hua Yulang was full of doubts about these barrels, the dozen people who followed him came together, and one of the soldiers said: "Military division, we have checked around here. It seems to be a storage warehouse. There is a hole leading to the outside, and the outside is the enemy's Dungeon. At this time, the dungeon is chaotic and no one pays attention to it. I think we can let the army in here and launch a surprise attack when they don't pay attention!"

When he heard the soldiers' words, Hua Yulang nodded, and then stopped paying attention to these barrels. After he wanted to come and capture the dungeon, he could investigate in detail what was here. Now the situation is so tense, how can he delay here?

On the other hand, long Tianci, Cao Youyi and Ge ye, three marshals, stood condescending on a cliff, and Hua Yulang holding a torch was tens of meters below. They stared at him for a long time. Ge Ye suddenly opened his mouth to Cao Youyi and said, "brother Cao, the enemy has fallen into the trap. When shall we start?"

"Don't worry, wait until the enemy comes in. This is our last resort. We must defeat the enemy at one stroke, otherwise we have no way back. Don't worry. Everything is within the calculation of God. These guys can't run!" Cao Youyi smiled unfathomably, then turned his head and looked at the Dragon Tianci around him. At this time, the Dragon Tianci was staring at Hua Yulang. His eyes were very strange.
