A cavalryman galloped to the front of Tumen Pass, stretched his bow and arrows, and shot an arrow letter to the city, and a soldier picked up the arrow letter and handed it to Li Wanquan.

This letter was not written by Guo Song, but by the general Yang Meng, demanding that Li Wanquan surrender within half an hour, otherwise the army would raze Tumen Pass.

With Li Wanquan's current situation and identity, it is not Guo Song's turn to write a letter to him to persuade him to surrender.

Li Wanquan is accurately said to be Zhu Tao's general, he was still a homeless orphan, he was adopted by Zhu Tao's father Zhu Huaiqi, and after growing up, he practiced a good martial arts and became Zhu Huaiqi's personal army leader.

After Zhu Huaiqi's death, he was successively reused by Zhu Jun and Zhu Tao's brothers, and it can be said that the Zhu family not only had the grace of nurturing him, but also the grace of knowing him.

After being silent for a long time, he shook his head and said: "The three generations of the Zhu family have treated me well, if I surrender, what face do I have to go to the lord?" ”

He brushed a few times, tore the letter of persuasion to shreds, and shouted: "As long as I am here, don't think of stepping over the hurdle!" ”

Time passed little by little, and the agreed time passed, and the defenders of Tumen Pass still had no intention of surrendering.

Yang Meng was furious and shouted: "Trebuchet prepare!" ”

The huge trebuchet was thrust forward by more than a hundred soldiers, and two hundred soldiers with large shields in their hands guarded the soldiers of the cart.

Li Wanquan has always served as a soldier and horse envoy in Hengzhou, did not follow Zhu Tao into Hedong to fight, has never seen the power of iron fire thunder, and no one has seen it with his soldiers, only occasionally heard of the name iron fire thunder, it is a very powerful weapon of the Jin army, but how powerful? None of them have any concept.

"Archer launch!" Li Wanquan gave an order, and more than a thousand soldiers fired arrows in unison, shooting intensively at the approaching trebuchet.

Li Wanquan was not worried about the enemy army in the west, which was condescending and the roads were narrow, and the mountain roads could be blocked with rolling wood and stones.

The main reason is that the east side is more dangerous, but the eastern half-mountain road near the pass is also relatively narrow, and it is impossible to launch a large-scale attack, and it may not be useful to have a large number of troops.

The dense arrows were blocked by the Jin soldiers with shields, and the trebuchet continued to move forward, only about sixty steps away from Guancheng.

The soldiers fixed the trebuchet, dozens of soldiers began to pull the throwing rod, several soldiers put a large iron fire mine weighing two hundred catties into the throwing pocket, Guo Song just promulgated the rules for the use of iron fire thunder, clearly stipulated, can only be used in the attack and defense of the city pass and water warfare, Tumen Pass is just allowed.

Arrows rained down on the city, and a firearms battalion commander lit the rope with a fire breaker, and when it reached the red line, the brigade commander shouted, "Fire!" ”

The soldier cut the drawstring and said, 'Bang! With a loud bang, the rod was thrown, and a huge black iron can flew towards the pass with green smoke, and the soldiers on the pass shouted, squatted down one after another, and the iron fire and thunder shot into the pass.

At the same time, all the Jin soldiers lay on the ground at the same time, tightly blocking their ears, and for a moment, they only heard an earth-shattering explosion, the earth was shaking, and this strong explosion made the hearts of the Jin soldiers seem to stop beating, only to feel the sand and flesh in the sky falling.

After a while, the soldiers slowly raised their heads, and the scene in front of them made them stunned, half of the Tumen Pass had disappeared, and the other half of the wall had also collapsed, revealing the fragmented buildings inside, which were full of mutilated corpses, and there was not a single living soldier in sight.

This large iron fire thunder can be called the most lethal iron fire mine, directly killed more than 1,000 people, seriously injured more than 300 people, and almost shattered the internal organs, can not be treated, 1,800 people in the pass, less than 100 soldiers survived, they hid in the room to survive, but these 100 people are also all deaf, hearing has been permanently damaged.

Without Tumen Pass, Liu Guanghui led 15,000 troops from Jingcheng to kill, and quickly joined the main force, so that the army led by Guo Song personally reached 50,000 people........

In Xindu County, Yao Jin's 30,000 troops still stood still, and after they set up a large camp twenty miles south of Xindu County, they never moved again, and there was no sign of an attack on Xindu County, and there was no plan to send troops to a decisive battle against Zhu Tao's army.

After nearly ten days of confrontation, Zhu Tao began to feel that something was not quite right.

His feeling that something was wrong came from Jing Cheng, and Zhu Tao also learned the news that the general Lu Jinsuo had fled back to Youzhou, and Zhao Zhou was lost, and the northern part of Zhao Zhou was close to Jing Cheng, so during this time, Zhu Tao had been waiting for news from Jing Cheng.

Unless the Jin army stops at Zhaozhou, there will be news from Jingcheng anyway, but will the Jin army stop at Zhaozhou?

Zhu Tao's second uneasiness came from Guo Song, of course he knew that Guo Song had arrived in Hebei, but the banner of the Jin army commander in Xindu County was still the word 'Yao', indicating that Guo Song did not come to Xindu, could it be that he was still in Zhaozhou?

Zhu Tao felt unlikely, Guo Song started by commanding troops to fight, he came to Hebei to personally lead troops to fight, how could he sit in Zhaozhou? It's better to sit in Chang'an.

After figuring it out like this, Zhu Tao became more and more scared, where would Guo Song be now? After ruling out all other possibilities, Guo Song could only go to one place, and that was Zhaozhou.

At this time, a soldier reported, "Lord Wang, Mr. Bochang is back." ”

Zhu Tao was overjoyed, and hurriedly said: "Quickly invite him to my big tent!" ”

Mr. Bochang is called Li Bochang, his ancestral home is Yingzhou, Liaodong, his father is a businessman, called Li Da, perennial in Khitan and Yan and other places to buy ginseng, and later married a wife of the Bohai State, then settled in the Bohai State, Li Da's wife gave birth to two sons, named Li Bochang and Li Zhongchang, Li Da made a fortune because of the sale of ginseng, invested a lot of money in the education of his son, and sent the eldest son Li Bochang to study in Youzhou.

After the death of his father, the family property was divided into two, and Li Zhongchang inherited his father's business and still settled in Bohai Kingdom, but the eldest son Li Bochang did not want to go back, he got a large sum of money, and traveled around the Tang Dynasty.

In the second year of Jianzhong, Li Bochang participated in the imperial examination in Chang'an, was admitted to the Ming Classics, and worked as a county official in Lantian County for a year.

Li Bochang's shrewdness, ability and resourcefulness gradually won Zhu Tao's attention, especially Li Bochang's fluent Khitan language, several times for Zhu Tao to envoy the Khitan, for Zhu Tao to get the support of the Khitan war horse made great contributions, and gradually became Zhu Tao's adviser.

Li Bochang is forty years old, and he has followed Zhu Tao for ten years, and he also married Princess Zhu Tao's cousin Zhang, and Zhu Tao has a little kinship.

"Mr. Bochang, you came back too soon."

Zhu Tao welcomed Li Bochang into the big tent, and said impatiently: "The situation is a little bad!" ”

"It's really not good. The prince should return to Youzhou immediately. ”

Zhu Tao was stunned, "Why did Mr. say that?" ”

Li Bochang said unhurriedly: "Does the prince still remember what I persuaded the prince at the beginning of the year?" ”

Zhu Tao couldn't remember it a little, and asked for a while, "I don't know what Mr. is referring to?" ”

"It's Guo Song, why didn't he directly kill Li Wujun last year?"

Zhu Tao suddenly remembered that at the beginning of the year, Li Bochang told himself that Guo Song had defeated Li Wujun last year, and he could completely destroy him with one breath and seize Li Wujun's territory in Wuzhou, but Guo Song retreated to Zhaozhou.

Li Bochang meant that Guo Song specially left Li Wujun as a bait to lure his army south, but he did not accept his analysis at that time, and still insisted that Guo Song withdrew his troops because of insufficient combat preparations.

This recognition is extremely important, it is related to whether or not he can start the north-south attack that his brother has planned for a long time, and more importantly, Guo Song has already seized Zhaozhou, and he is also going to get involved in Hebei, leaving them little time, so Zhu Tao is eager to promote the strategy of unifying Hebei, so he ignores Li Bochang's reminder.

Judging from the current situation, it is really a bit like what Li Bo often said, Guo Song left Li Wujun as bait.

But he felt that something was wrong, he and his eldest brother had planned to unify Hebei for many years, regardless of whether Guo Song destroyed Li Wujun or not, this battle between the north and the south was imperative, and Guo Song left Li Wujun not to attack last year, isn't it a bit redundant?

Zhu Tao forgot one thing, Guo Song didn't know the strategy between him and Zhu Zhu, and he had recently discovered that Zhu Zhu's army had moved and transferred the ship to the north, so Guo Song faintly guessed a few points.

"Bo Chang, there's no point in saying this now!" Zhu Tao heard him mention the old things again, and his heart was slightly unhappy.

"Nope! This matter is the key to the whole situation, it depends on whether the prince can accept my point of view? ”

"Alright! Even if it's bait, so what? ”

"Lord Wang, if Xindu County is a bait, then Guo Song's target is probably not just Li Wujun."

Zhu Tao jumped up, grabbed Li Bochang's wrist and said urgently: "You shouldn't say that Guo Song led the army to attack Youzhou, right?" ”

"I just said that the situation is serious, but that's what I mean!"

At this moment, a soldier outside the tent said loudly: "Lord Wang, there is urgent news in Yizhou!" ”
