Reason told Lin Feng that Black Flag Pass was facing the possibility of missing at any time, and it must be rescued immediately. In particular, Liu Xuanyuan mentioned in the blood book that the Rong people had the siege equipment of the Song State, which caused immeasurable trouble to the front-line soldiers. At this time, Lin Feng realized that there was a special unit in this era.

He remembered that when he was in school, there was an article describing the dialogue between Gong Losing and Zi Mozi, and the two sides defended and attacked, and they were all siege equipment. Later, when I was in the military school, I came into contact with an anime that depicted the mechanism of the Mo family and the public loser, which was even more unpredictable and so powerful that it was difficult for manpower to resist.

At present, Lin Feng doesn't know if the mechanical troops of the Song Kingdom, as well as the offensive and defensive equipment, are as powerful as the mechanism skills of the Mo family and the public loser in the anime.

However, Liu Chengfeng mentioned in the blood book that the siege equipment of the Rong people, the ladder car and the siege vehicle are more than 30 meters high, and the trebuchet throwing distance is more than 1,000 meters. Thinking of how powerful the mechanical troops of the Song Kingdom were, Lin Feng felt a chill in his heart.

Fortunately, there is no conflict with the Song State at present, and there is time to consider a solution. However, the Rong people attacked fiercely for four consecutive days, and the soldiers defending the Black Flag Pass suffered heavy losses, and Liu Xuanyuan mentioned in the blood book that the Rong people might adopt a wheel battle and attack the Black Flag Pass again. If they can't get rescue in time, the whole army of Black Flag Pass will be dragged to death by the other party and fall into death.

The only thing that made Lin Feng happy was that not long after Liu Xuanyuan sent the blood letter, Bai Yisheng also sent a messenger to send a battle report, which described in the letter that Bai Yisheng, Huan Bangchang, Zhang Yu, and Zhao Jun led the troops to annihilate the tribes and troops that provided food and grass for the Rong army, causing the tribes close to the Black Flag Pass to begin to retreat, and the Rong people's military rations could not be effectively replenished, and they might step up the attack on the Black Flag Pass, and the four of them would choose a suitable time to ambush.

After being happy, Lin Feng was unhappy again, the advantage of the light cavalry was that there was no trace, there was no shadow, and there was a long-distance attack. Bai Yisheng and the four of them still didn't have much experience in leading troops, so they didn't take the initiative to attack the Rong camp, but chose to ambush. This can cause harm to the Rong people, but it cannot solve the crisis of Black Flag Pass.

"Xianggong, is it a front-line military newspaper?" The queen was sitting in the carriage, and when she heard a messenger coming up outside, she opened the curtains, and saw that Lin Feng had read the military newspaper, her face was sad, as if she had something on her mind, and couldn't help but ask.

Along the way, there was a messenger who reported the battle situation at Black Flag Pass, and Lin Feng did not realize it as much as now, he was a little angry, anxious, and cold, the queen was a careful woman, even if Lin Feng didn't say it, how could he not see the weight of the military report.

Lin Feng barely squeezed out a smile, smiled very ugly, and shook his head: "Xue'er, it's okay, I'll take care of it!" ”

The war is cruel, since he can't stop the queen from walking with her, Lin Feng can only let the queen be affected by the battle array as much as possible.

"Zhao Hongru, immediately lead the heavy infantry, and 40,000 dragoon guards, non-stop rush to the Black Flag Pass, even if the war horse is tired to death, it must arrive at the Black Flag Pass at the right time." Leaving the queen's sight, Lin Feng suddenly became cold, and threw the blood book and military report to Zhao Hongru, after Zhao Hongru understood the current situation of the Black Flag Pass, Lin Feng said sharply: "The terrain of the Black Flag Pass is strange, there are five or six miles of mountain roads, which are not suitable for cavalry impact, after arriving at the Black Flag Pass, you cooperate with Huangpu Xuan, organize a death squad, take the heavy infantry out of the pass, and defend the mountain pass and the surrounding mountains, and absolutely cannot let the Rong people's siege equipment get close to the Black Flag Pass." ”

"Yes!" Zhao Hongru learned that the Black Flag was about the war, and he did not dare to delay, so he immediately transferred his troops and left. At the same time, Lin Feng summoned a messenger and sent a message to Bai Yisheng and the four people.

Lin Feng's biggest reliance at present is Yu Linwei, and most of Yu Linwei are cavalry, but the 20,000 elite ironclad cavalry are nested in the Black Flag Pass, and they can't give full play to their advantages at all, which makes him very annoyed. Bai Yisheng and four people led 40,000 light cavalry to annihilate the Rong tribe's grain transportation team, which was indeed good, but he did not directly attack the Rong cavalry to relieve the pressure on the Black Flag Pass, Lin Feng was very dissatisfied.

The cavalry should move, out of nowhere, constantly attacking, harassing the Rong battalion, and choosing the right time to attack, this is what Lin Feng asked Bai Yisheng and the four of them in his letter.

After Zhao Hongru led the troops away, Lin Feng led 10,000 dragoons to drive the ploughing cattle and inferior horses, and also accelerated the speed.

The Black Flag Pass was closed, and the battle started again in the afternoon, and taking the Black Flag Pass was a matter of life and death for the tribe, and Yelutelle was not allowed to do his best. At the beginning, he took out the tribe's old bottom, and there were far more siege equipment than Yelu Iron Stone, which was being transported to the Black Flag Pass Mountain Road in a steady stream.

The soldiers, who had only rested for two hours, got up again, cheered up, and waited to meet the enemy when the Rong people came. Fortunately, the young people in the Guannai, who took out weapons from home, also poured onto the city wall, accompanied the soldiers to resist the enemy together, and there were many people in this wave, about 5,000 people.

"General, the power of the opponent's siege equipment is too powerful, and it is not a way to defend the Black Flag Pass! Moreover, the Black Flag Pass is too late to be repaired, and I am afraid that it will block the attack of the Rong people, and the last general is willing to lead the ironclad cavalry to rush out of the pass and block the opponent's siege equipment from approaching. Looking at the siege equipment that appeared at the mouth of the mountain road, thinking of the previous battle, the threat of the siege equipment to the Black Flag Pass, and then looking at the half of the ruined city wall, Feng Shihu took the initiative to ask for battle.

"No, the mountain road is too narrow, and the cavalry does not have any advantage, otherwise, the Rong people will not use siege equipment to attack the city." Liu Xuanyuan refused Feng Shihu without hesitation, but ordered to Huangpu Xuan beside him: "General Huangpu, immediately let the crossbowmen bring fire, oil, and all the young people who spontaneously defended the city, and take advantage of the fact that the Rong people have not yet launched an attack, go to various mountains, block the Rong siege equipment from approaching the Black Flag Pass, tonight, even if the mountains are burned, the Rong people cannot be allowed to step into the mountain road half a step." ”

In the previous battle, Liu Xuanyuan and others won a miserable victory, recaptured the various hills that were lost before, and the front end of the battle line was transferred to the mountain pass, and the only remaining 5,000 tiger and leopard battalions at this moment were guarding the various hills.

"Yes!" Huang Pu Xuan arched his hand, and then said to the crossbowmen and the young men who joined the army: "Brothers, bring fire and oil, divide into two groups, and quickly go to the mountains outside the pass to resist the enemy." ”

After Huangpu Xuan left, Liu Xuanyuan took a deep breath, coughed violently continuously, turned to Feng Shihu and Hou Mingfeng and said: "It's all up to us to defend the city, if General Huangpu can't stop the Rong people with fire, you abandon the pass and go south, use the advantage of the ironclad cavalry, and ambush the Rong cavalry near the Black Flag Pass and the Wolf Pass, I will organize the remnants of the army, hold on until the last moment, and live and die with the Black Flag Pass." ”

"General, are you going to give up General Huangpu and more than 20,000 people outside?" Feng Shihu asked anxiously. He and Huangpu Xuan knew each other when they followed the emperor to fight outside the Saiwai, and after several months of training in Cangyan Mountain, the relationship between the two became more and more intimate. Hearing that Liu Xuanyuan asked the two of them to abandon the city and flee after the defeat of Huangpu Xuan, he couldn't believe it.

"Yes, General Liu, the strength of the crossbow soldiers is not weak, and the emperor is very important." Hou Mingfeng also hurriedly stopped it, and even moved out of the emperor's name.

Liu Xuanyuan's face was pale, without any bloodshots, he had experienced life and death battles in a row, and he had seen too many brothers fall in front of him, and his feelings were numb. "No matter how powerful the crossbowmen are, they can't beat the ironclad cavalry, in the tiger and leopard camp, although there are no ironclad cavalry, I also know that the cost of training the ironclad cavalry is ten times that of the archers, the emperor has no money, I can't wipe out his family in one battle. There are 20,000 ironclad cavalry, and the emperor still has to rely on, even if the country is destroyed, he can make a comeback, but the tiger and leopard battalion and crossbow soldiers outside, and more than 5,000 young warriors, may not be able to help the emperor. ”

Liu Xuan is far from alarmist, let alone deliberately delaying the fighter, he has no personal feelings in his heart, and in the blood letter sent to the emperor at noon, he has already expressed his thoughts.

To say that he deliberately gave up the 20,000 people outside is absolutely impossible. The tiger and leopard battalion in the Black Flag Pass, after he came to the Black Flag Pass, he trained it single-handedly, from the beginning of June to block the Zuo Xian Wang Department Godo, he recruited two years ago, half of the soldiers he recruited two years ago, half of them died, and in the past six months, he recruited 30,000 new troops, several days of fierce fighting, 40,000 tiger and leopard battalion soldiers only 5,000 remained, every time a brother fell, he felt as if there was a knife stirring in his heart. When the battle came to this, he also had a bag. But for the sake of the bigger picture, he had to give up the Haw Par Battalion, the brothers who got along with him day and night.

Otherwise, the left wing of the Rong army almost destroyed the city wall of the Black Flag Pass, under the impact of the 100,000 troops on the right wing of the Rong people, and the onslaught of various siege equipment, the Black Flag Pass simply blocked the opponent's attack, and the catapult launched three or five waves of attacks, which could completely destroy the city wall of the Black Flag Pass.

Once the Rong people break through the pass, will they continue to defend to the death, in the street battles in the pass, the ironclad cavalry cannot give full play to their advantages, how can they block the 100,000, or even the endless Rong cavalry behind.

He felt more uncomfortable than anything else at giving up his brother in life and death, and reason told him that he had to do this, or he would face the tragic destruction of all his army, including the elite ironclad cavalry.

Last night's fierce battle, I have seen too many bloody killings, Huangpu Xuan is at the forefront, responsible for resisting the Rong people into the mountain road, this will also be calm, without the slightest fear of panic.

After more than 20,000 soldiers occupied the various hills, everything was quickly arranged, and Huang Puxuan did not let the soldiers attack immediately, but let the soldiers guarding the mountain pass take the initiative to let the Rong siege equipment in. His eyes were condensed, and he stood behind a boulder, staring at the Rong people slowly advancing, with a weird smile on the corner of his mouth.

The cold wind on the mountain was fierce, the wind poured into the valley, the wind in the valley was fierce, the wind was crying and howling, and the soldiers on both sides carried out their respective tasks with strong winds on their heads, braving the severe cold.

At this time, Huang Puxuan looked up at the gray sky, the black clouds were rolling, the sky was dim, and with the roar of the wind, as if a group of demons and monsters were haunting, slowly rising from the northern sky, wanting to devour the entire earth.

"It's going to change!" Huang Puxuan raised his hand, touched the sparse stubble, and muttered.
