When Cai Hejian led the large army to slowly approach the North Gate Fortress, the gate of the fortress had slowly risen at this time, and Cai Hejian saw this and ordered someone to step forward and order the defenders on the fortress: "Elder Hejian has an order, and he ordered Er to report the information in the mining area as soon as possible." ”

Li Xian poked his head out of the hole in the wall in a panic, and said loudly with an eager face: "My lord, you are finally here!" Now there is a big chaos in the mining area, the thieves of Heishi Village have already invaded the mining area, and Commander Cai Lin has already led people to rush to support. He told the villain before leaving, and as soon as the adults arrived, he immediately notified the adults to rush to help!"

Cai Yi and Cai Lin are both commanders, and they are very good on weekdays, and when they heard that Cai Lin needed support, they immediately asked Cai He and Jian for instructions: "My lord, do you want to let the lowly lead someone to see the situation first?"

Cai Hejian glanced at the fortress with the gate open, and under the light of the blood moon, only the dim torches set off the fortress surprisingly gloomy, which made him a little more worried.

He thought about it, then nodded and told Cai Yi: "Well, you go! Be careful on the way, and if there is anything wrong, retreat first!"

"Humble duty understands!"

Cai Yi turned around and took the hundred most elite scouts under his command, riding the beast and running towards the dark doorway.

The torches in the doorway were dim, and the surroundings were extremely dark, which made the cavalry who had just passed through the doorway have a great impact on their visual distance, so that they could not detect the anomaly in the darkness in the distance.

Although his eyes were affected to a certain extent, Cai Yi, who had been tense, suddenly noticed some abnormalities. On the empty field behind the gate of the fortress, although there are no obvious traces of battle, for a general who has been fighting all year round and is accustomed to seeing blood, the thick smell of blood in the air cannot be concealed.

Cai Yi stopped his mount abruptly, then turned the beast's head and rushed towards the doorway.

"Retreat! There is an ambush!"

Cai Yi's scouts were all very elite soldiers, and when they heard Cai Yi's shout, they immediately turned the beast's head and followed Cai Yi to the direction of the door.

"Close the door!"

The moment Cai Yi turned the beast's head, Yan Qiu immediately gave the order to close the gate. With the rapid rotation of the winch, the heavy gate descended rapidly, and Cai Yi rushed out of the gate with more than a dozen guards the moment before the gate closed.

But the other scouts under his command were not so lucky, and the heavy gate completely blocked their retreat.

These scouts were veterans of many battles, and they were very experienced in facing the enemy, and the moment they saw the gate closed, they did not attack the gate, but immediately turned the beast's head and rushed all the way to the previous direction at full speed, trying to make a way out of the mine.

However, their calculations were doomed to fail, and the road ahead was also a dead end, and the passage to the mining area had long been blocked by dense wooden walls. When they rushed to the front of the wooden wall, they were greeted by a group of soldiers armed with strong crossbows, and when they saw the dense array of crossbow arrows aimed at them all around, they knew that this was the end.

"Put!" "Put!" "Put!"

Three orders to attack in a row, three waves of arrows rained down on them at once, and although they tried their best to dodge, it all seemed so futile. When the three waves of arrows passed, the more than eighty elite scouts were all filled with arrows and fell to the ground.

Cai Yi escaped from the door with more than a dozen of his men, he galloped all the way, ran towards Cai Hejian's army, and shouted before he got close: "My lord, there is an ambush!"

The moment Cai Hejian saw the gate of the fortress closed, he immediately realized that something was wrong, and he immediately stood up and looked at the rapidly descending gate, hoping that Cai Yi could bring the scout troops back safely.

But it backfired, and when he saw that Cai Yi had only brought back a dozen scouts, he slowly sat down again, because he knew that it was useless to regret it now.

"What the hell is going on?" Cai Hejian asked Cai Yi with a grim face.

"There was a large-scale battle behind the fortress, and the strong smell of blood could be smelled far away, and there must be spies on this fortress!" Cai Yi said anxiously, looking back from time to time, obviously very worried about his subordinates being locked in the door.

"My lord, let's think of a way! There are more than eighty scouts locked in the door!" Cai Yi was very anxious, and he asked Cai Hejian with a concerned expression.

Cai Hejian closed his eyes, took a deep breath, and then slowly opened his eyes and stared in the direction of the city tower and said, "I'm afraid it's too late!"

"What?" Cai Yi looked stunned.

At this moment, three clear voices suddenly came from the city, "Release!" "Release!" and "Release!"

Cai Yi asked in disbelief with a trembling mouth, "Dead?。。。 Are they all dead?"

Cai Hejian set his sights on the fortress tower at this time, and the opponent on the city tower had not yet appeared, so he lost eighty percent of the elite scouts, which made him ignite a raging fighting spirit.

It had been a long time since he had encountered an opponent who dared to challenge the authority of the Cai family, and no matter who this opponent was, he would have to pay a terrible price for it today, otherwise it would be difficult to eliminate the hatred in his heart.

"Pass on my military order, the whole army will be deployed, and prepare to attack! I want these people in the fortress to know what kind of fate will happen to those who dare to challenge our Cai Clan's authority!" Cai Hejian's eyes were full of fierceness, and he ordered coldly.

"Yes, my lord!" Cai Yi finally recovered from the sudden blow, he turned to his subordinates and said, "Immediately start a formation, prepare to attack, and avenge your brothers!"

"Yes!"

Cai Hejian's team immediately spread out to both sides, and as the number of people increased, the open space in front of the fortress was instantly occupied, and the others had to expand into the surrounding grass.

"Oops!"

The screams suddenly disrupted the formation of the troops, causing a lot of confusion among the troops.

Cai Yan frowned, and scolded these chaotic soldiers: "Bastard, dare to disturb the formation, and immediately drag them out to serve in military law!"

"My lord, it's wronged! It's a hidden weapon in this bush, and we didn't mean it!" a soldier with a wounded leg showed Cai Huo the "riding thorn" pulled out of the sole of his foot, and begged for mercy.

Cai Yan reached out and took the "riding thorn" that was still stained with blood, and looked at it carefully, and he found that this was a hidden weapon that he had never seen before.

He immediately brought the strange hidden weapon in his hand to Cai Hejian, and said to Cai Hejian: "My lord, the enemy has laid a strange hidden weapon in the grass, and many soldiers have caught the way. Look, my lord, this is that kind of secret weapon!"

Cai Hejian stretched out his hand to take the hidden weapon, and then looked at it carefully, his eyes were unconsciously attracted by the sharp nails on the "riding thorn". Such a sharp nail, inadvertently stepping on it, will indeed bring great harm to people, but if it is a riding beast in a high-speed gallop inadvertently stepped on, then the consequences may be more serious.

Thinking of this, Cai Hejian basically figured out the role of this hidden weapon, and he immediately ordered the soldiers to carefully search the grass first, and sure enough, a large number of "riding thorns" were found in the grass.

Seeing that the "riding thorn" he arranged was discovered by Cai Hejian's troops, Li Xian was a little depressed, and he said to Yan Qiu curtly: "Boss, it's all because I didn't do it well, and I couldn't let the "riding thorn" exert its due power. ”

Yan Qiu glanced at him, and then said with a smile: "It's nothing!" "Riding Thorn" is just an appetizer, and being found will not affect the overall situation, and the next thing is the real show. ”

At this time, Cai Hejian's troops had already launched an offensive formation, looking at the fortress in front of him that the family had spent many years of hard work building, Cai Hejian's face became colder and colder, and he immediately issued the mission of attacking: "Start attacking immediately and take the fortress back!"

"Yes!"

Cai Yi and Cai Yan immediately led their subordinates and launched the first wave of offensive towards the North Gate Fortress.

The soldiers held their shields and rushed towards the fortress wall, and some of them carried a number of long ladders, which were used to climb the wall, and when they rushed to the bottom of the wall, they only had to lean the ladder against the wall, and the soldiers behind them could go up the ladder and attack the fortress.

In the face of the Cai soldiers rushing quickly, many soldiers in the city were so nervous that cold sweat broke out in their palms, and they held the crossbow arrows in their hands tightly, ready to shoot at the enemy at any time.

However, seeing that the enemy was approaching the city wall, and the order to attack was delayed, Yan Qiu was not issued, and Da Niu asked Yan Qiu very anxiously: "Boss, the enemy is about to attack at his feet, why don't you give the order to attack?"

"Listen to my orders, wait until the enemy is close before fighting, be sure to destroy more of the opponent's troops, people won't let us have too many opportunities like this!"

"Oh! Got it, Boss!"

When most of Cai's soldiers rushed to the bottom of the wall and were erecting ladders to climb up the wall, Yan Qiu finally spoke: "Attack!"

"Buzz!" "Buzz!" "Buzz!"

Thirty bed crossbows fired at the same time, and ninety giant arrows with a huge whistling sound pierced the crowded crowd fiercely, striking layers of blood waves in the crowd.

"Boom!" "Boom!"

The dense rain of arrows poured wave after wave towards the defensive pit opened by the bed crossbow, once again striking layers of blood waves, making the entire offensive formation have a large number of wounds.

Although they faced a huge number of casualties, they could not stop the attack of the Cai soldiers, and one by one, they climbed towards the fortress wall, believing that as long as they could climb the wall, then they would achieve the final victory.

"Boiling oil waiting!"

With Yan Qiu's order, the oil pot, which was already boiling endlessly, poured towards the Cai soldiers who were climbing upwards one by one. The boiling hot oil made many soldiers scream and roll downward, and the overflowing boiling oil also burned the soldiers who were waiting to climb under the city.

"Logs, rolling stones waiting!"

Yan Qiu's terrifying voice sounded again, and huge logs and huge boulders continued to fall from the city walls, smashing down many long ladders along with the soldiers who were climbing on them. The logs and boulders were so powerful that they smashed many of the long ladders and rendered them unusable.

"Rockets waiting!"

As the evil voice of Yan Qiu sounded again, one after another burning arrows, like meteor showers in the night sky, shot densely towards the city. As soon as the rockets came into contact with the logs and boiling oil, they immediately ignited a raging fire, turning the city into a sea of fire in an instant.

Cai's soldiers hurriedly retreated from the city in a hurry amid the constant screams, and seeing their subordinates so defeated, Cai and Jian were immediately furious.
