In a month, Yelu Zongzhen ordered the army to besiege Gubeikou for a whole month, and the 80,000 troops attacked in turn, not even resting at night, and not only from the front, Yelu Zongzhen even attacked from the mountains on both sides, wanting to directly attack the rear of the Song army after laying down a section of the Great Wall.

But it's a pity that the terrain of Gubeikou is too dangerous, and it is impossible to launch a large army in the mountains on both sides, so the little army of the Yelu Sect is of no use at all, but has lost a lot of manpower.

In the face of this situation, Yelu Zong really tried his best, and even thought of digging dark passages, water attacks and other methods, but it was useless, Xi Guan was like a stubborn nail, nailing them to Gubeikou, not to mention recapturing the sixteen states of Yanyun, and he couldn't even move forward half a step.

"Woo woo~" With a dull sound of horns, the Liao army attacking Xiguan also slowly retreated, like the ebb tide of the waves, but after the sea water receded, what was left behind was not sand, but corpses and blood in a place.

Soon there were Liao troops coming to the battlefield with white flags, they did not surrender, but to carry the wounded Liao army back, and the Song army did not attack them on their side, not that the Song army was merciful, but that the Song army knew that instead of letting these wounded Liao soldiers die on the battlefield, it was better to let them be rescued, so that they could also consume the Liao army's grain, grass and medicine, and the materials in the Liao army were already very scarce, so these wounded soldiers were a big burden for the Liao army.

Of course, Yelu Zongzhen knew the plans of the Song army, but he couldn't let these wounded soldiers go, because the Song army had made it clear that he had promised to let them treat the wounded soldiers, if he let those wounded soldiers wait to die on the battlefield, it would only make the morale of the army on his side lose heart, not to mention driving these soldiers to die for him, in the face of this kind of conspiracy, Yelu Zongzhen could only pinch his nose and swallow this cup of bitter wine.

Looking at the Liao army that retreated like a tide, Di Qing also wiped the blood on his face, just now there were several Liao troops killed in the city, one of which was in the area of the city wall that Di Qing was responsible for defending, but they were quickly killed.

Originally, with Di Qing's current identity, he no longer needed to go into battle to kill the enemy in person, but he liked the feeling of blood boiling when killing the enemy, especially when the enemy's blood sprayed on him, every time Di Qing felt a tremor in his soul, it seemed that this was the life that a man wanted.

"Brother Di, why did you go into battle in person again?" At this moment, I saw Cao Tong walking over with a human head, and when he saw Di Qing's bloody appearance, he couldn't help but laugh, the area he was responsible for defending was just next to Di Qing.

"If you can still use a knife while you are young, of course you have to kill a few more, and you also know that muskets are becoming more and more popular, and I am afraid that there will be few opportunities for hand-to-hand combat on the battlefield in the future." Speaking of this, Di Qing looked at the human head in Cao Yan's hand, and immediately smiled again, "What, kill a big fish?" ”

"Hehe, a little general, it is estimated that he can exchange a lot of military merits." Cao Tong raised the head in his hand at this time, although the Liao State claimed to inherit the Tang system, but after all, it is a nomadic people, and the military system is also very extensive, for example, the position is very general, and the generals at all levels are called small generals, generals, generals, generals, etc., but even if it is a small general, it is also a high-level in the Liao army, and Cao Tong can kill a small general, which is indeed a great achievement.

"Luckily, your men have meat to eat again today!" Di Qing also smiled when he heard this, killing a Liao general of this level will not only be recorded as a military merit, but also an additional reward, of course, there is nothing else on the battlefield, it is nothing more than a reward for some delicious food to reward the soldiers.

Cao Tong also laughed when he heard this, and then handed over the head in his hand to his subordinates to report his merits, and then pulled Di Qing to the side and asked: "Brother Di, Yelu Zong has really been attacking for a month, and the Liao army outside the city has suffered heavy casualties, if I were him, I'm afraid I would have withdrawn a long time ago, but now looking at his appearance, he has no intention of retreating at all, this guy doesn't really want to fight us to the end, right?" ”

"Hehe, I have also analyzed Yeluzong's real character, this guy is the kind of person who doesn't hit Nanshan and doesn't look back, the reason why he sent troops at the beginning was that he thought that our Great Song Dynasty was muddy, but now he has hit a head of blood, but if he retreats, he will definitely lose face, so now he can only hold on."

When he said this, he saw Di Qing pause for a moment and then said: "But I don't think Yelu Zongzhen will last long, not to mention that the weather is getting colder and colder, it may snow at any time, and the supplies of the Liao army must have bottomed out, if you don't go back, I'm afraid these 80,000 Liao troops will starve." ”

"If the Liao army retreats, wouldn't it be a great opportunity, will General Liu send troops to chase and kill?" Cao Yan's eyes lit up when he heard Di Qing's words, and he immediately asked again.

"Definitely, didn't you see that General Guo didn't appear in the city during this time, if my guess is correct, General Guo has probably left here and quietly lurked outside the city from other places, ready to attack the Liao army at any time!" Di Qing looked left and right at this time, and then lowered his voice and said again.

"Great, if General Guo can intercept a part of the Liao army, we can also take advantage of the situation from the city, and then we will have another opportunity to make great contributions!" Cao Yan's eyes also lit up when he heard this.

Looking at Cao Yan's longing look, Di Qing suddenly felt a little strange, and said half jokingly and half seriously: "You kid don't need to work so hard, your sister is now the queen, and you are also the uncle of our Great Song Dynasty, this military merit is simply dispensable for you." ”

"A manly man, of course, you have to rely on your own strength!" Cao Tong immediately glanced at Di Qing and said, but when he spoke, he sighed secretly in his heart, because he had received a letter written by his sister, and he also knew that although his sister was a queen, she was not favored in the palace, so his identity as an uncle would not only not help him, but might also affect his career, so he had to work harder than others.

Of course, Di Qing didn't know about the affairs in the palace, although he also had correspondence with Li Zhang, but these secrets in the palace Li Zhang would definitely not talk nonsense, not to mention that this was also related to the major matter of the emperor's discord, and it was very serious, so except for a few people, other people didn't know that Empress Cao was snubbed.

"Woo woo woo~" At this moment, I suddenly heard a passionate horn sound outside the city again, and then I saw another Liao army coming, which made Di Qing and Cao Tong also scolded secretly, it seems that the Liao army is planning to fight at night, which made the two of them immediately jump up and rush to their respective city walls to wait.
