Hearing long Tianci's order, the dungeon army immediately took action. The three named troops responded quickly. Under the command of the commander, the three troops quickly integrated into one, and then formed a shield and armor array to block the canyon mouth. At the same time, long Tianci began to retreat with his remaining soldiers.

Although the enemy was also startled by the suddenly collapsed city wall, the reaction was still rapid. Under the order of Hua Yulang, all the soldiers of the Imperial Army rushed to the canyon mouth. It seemed that they were going to rush into the canyon from the valley mouth at one breath!

In the valley mouth, the two armies clashed head-on again. Although long Tianci left only three teams of 10000 people, 30000 people are enough to completely seal the valley mouth with the width of the valley mouth. Even if there are hundreds of thousands of troops opposite, it is impossible to directly break through the garrison of the valley mouth and rush into the valley!

The battle was more tragic than the previous city defense battle. The soldiers in the dungeon guarded the canyon mouth with the determination to die. The enemy also attacked desperately with the consciousness of breaking the boat. The soldiers on both sides seemed crazy. The atmosphere of killing in the battlefield was like pressing a huge stone.

Although the number of the imperial army is dozens of times more than the dungeon army guarding the canyon mouth, due to the limitation of terrain, only 8000 people can directly conflict with the dungeon army at one time. If the soldiers behind want to rush up, they can only wait for the soldiers in front to die. The two sides have fought a pure war of consumption, The dungeon army will not let go if it is not dead and clean, while the imperial army is purely employing people. Under this desperate fighting method, the casualties of both sides are very heavy!

On the other hand, long Tianci took advantage of the 30000 death squads in gukou to block gukou. During this time, he organized ground troops to quickly push into the dungeon along the military path. Originally, long Tianci wanted to meet the three troops blocking gukou after other troops withdrew into the dungeon, However, when all the other troops withdrew underground, long Tianci found that more than 30000 soldiers blocking the canyon mouth had been killed and injured more than half. The enemy rushed forward madly relying on the number advantage. It seems that 30000 soldiers at the canyon mouth are about to be overwhelmed!

Although they are reluctant to give up, they must be aware of the choice. Sometimes they must give up for the sake of the overall situation, and the current situation needs long Tianci to make the final choice!

Staring at the mouth of the canyon where flesh and blood become a river, the eyes of long Tianci gradually turn red. It's really hard to see his soldiers fall in a pool of blood with his own eyes. It can even be said that it's unbearable. However, the more this time, long Tianci has to be patient. After all, he is not only carrying the lives of these soldiers, What's more, Mo shook the lives of father and daughter in heaven and millions of people in Earth City!

Long Tianci clenched his fists and bit his lips. Maybe he was too hard. Long Tianci's lower lips were bitten by himself, and the blood trickled slowly along his chin, but long Tianci seemed to feel no pain at all!

Just as long Tianci's eyes were red and staring at the soldiers still struggling at the canyon in the distance, Cao Youyi suddenly rushed back, grabbed long Tianci and shouted, "what are you doing? The army has been pulled in, and the military road will be sealed soon. We will start the last resort. Come in!"

Hearing Cao Youyi's words, long Tianci reacted from the Leng God. After another look at the fierce battle at gukou, he gritted his teeth and turned with Cao Youyi into the deep part of the military path. At the same time, the entrance of the military path was sealed by a huge stone gate weighing 10000 kg. This stone gate is Cao Youyi's so-called last resort. It is called broken dragon stone. This stone is natural, It is three meters high, ten meters wide, at least one meter and five meters thick, and weighs almost 20000 kilograms. When processing this stone, an iron bolt with tension spring was specially embedded in the stone slot. As long as the stone is put down, the iron bolt will completely fix the stone. No matter what means you have, it is impossible to open the stone door from the outside!

Hearing the roar of the broken dragon stone falling behind them, the dungeon soldiers in gukou desperately blocked the enemy realized that all the troops had evacuated safely, and the hanging hearts of these bloody soldiers fell down. They were all people without father, mother, wife and children, and most of them were orphans. Cao Youyi took them in to eat and drink for them, In fact, they know very well that the purpose of Cao Youyi's taking them in is to hope that these carefree people can become death squads at the critical moment. It is common to say that their responsibility is to protect the dungeon and their comrades in arms with their lives. Their only belief is to complete their tasks. Therefore, after all the troops safely withdraw into the dungeon, these soldiers are relieved.

The left and right are also dead. As the saying goes, killing one is enough to kill two and earn one. These soldiers who were originally cannon fodder have no scruples at this moment. There is only one idea in their hearts, that is, to strive for more people before they die.

In this state of mind with the determination to die, the remaining thousands of people no longer simply defend gukou, but rush towards the enemy like crazy. Although each of them is covered with blood, they can't see any fear of death on their faces. Not only are they not afraid, these guys are still smiling. Their smile is very ferocious, With their bloody image, they look like evil spirits climbing out of the depths of hell!

Unfortunately, no matter how vicious ghosts and gods are, they can't make a difference in the face of hundreds of thousands of troops. After rushing into the enemy group, the only few thousand soldiers just set off a small wave in the enemy army, and then they were completely swallowed up by the crowd.

Hua Yulang, who had been pressing the army, saw that he had finally broken through the city wall and entered the canyon. His face showed a satisfied expression. It seemed that his strategy was correct. Under the great pressure of losing food and grass supplies, the soldiers gave full play to the ultra-high combat effectiveness they had never had before. It was with this combat effectiveness that they could succeed, Now that the enemy's defense line has been broken through, the rest is to break through the so-called dungeon and capture the culprit Mo Zhentian and his daughter. Then everything will be over!

On top of every act and every move, the old eunuch who started to shake the sky was in fact very familiar with them. Even the design of this land town was controlled by them. If they wanted to break through the valley, they could break through the city, which was almost a pediatrician. The battle was almost over.

Unfortunately, Hua Yulang was completely wrong. The traitor had long been found out, and Mo Zhentian and others had mastered many things about the imperial army from the old guy's mouth. Some entrances and secret roads of the former dungeon have become deadly traps or traps after this period of transformation, Hua Yulang asked the army to enter the dungeon according to their own dungeon entrance. After entering the dungeon, the soldiers who went down went in or out. According to the scream from those entrances, all the people who went down should be dead!

Realizing that the situation was wrong, Hua Yulang dared not let the army enter the dungeon casually, so he temporarily let the army stationed in the open space not far from gukou and went back to ask the crown prince for advice.

The prince was excited because Hua Yulang successfully broke through the canyon defense. According to his idea, if the canyon was broken, the war was actually over. Who knows that Hua Yulang came and told him that the dungeon could not enter at all, which made the prince furious and gave a dead order. There is no need to open the entrance of the dungeon before dawn today.
