There are generally three routes from Hedong Road back to Guanzhong, one route is Longmen River Jindu, followed by Pujindu in the south, if these two roads can not be taken, then you can only take the third road, first cross the Yellow River to the south bank, and then take Tongguan from the south bank to enter Guanzhong.

On the south bank of the Yellow River is Hongnong County, at this time when the Wagang army besieged Luoyang tightly, Hongnong County was also tense at the same time, Hongnong Taishou Yang Gongren recruited tens of thousands of soldiers to be tightly deployed to prevent the Wagang army from dividing troops to attack Hongnong County to the west.

Although Yang Gongren also wanted to lead the army to support Luoyang, he knew that his troops were weak, and he was afraid that not only could not save Luoyang, but would set himself on fire, and Luoyang stayed behind Wang Shichong to lead the troops to resist the Wagang army for nearly two months, Luoyang still held on, on the contrary, the offensive of the Wagang army was gradually weakening, and the time for the Wagang army to retreat was not far away, which made Yang Gongren's heart that had been tense for two months finally relaxed slightly...... Get down.

Yang Gongren is the eldest son of Yang Xiong, the king of Guan, about 40 years old, although he was born in the royal family, but he is honest and generous, capable and loves the people like a son, and has won the popularity of the people in Hongnong County.

In the evening of that day, Yang Gongren was sitting in the study reading a book, and a housekeeper came to report, and there were guests visiting outside the door, who came from Chang'an.

Yang Gongren was stunned, he took the post and looked at it, the post was very vaguely written, "The Prime Minister's envoy visited" Of course, the Prime Minister meant Li Yuan' This cannot be questioned, but what is Li Yuan looking for himself?

Yang Gongren and Li Yuan have an excellent personal relationship, and often exchange letters, but since Li Yuan's uprising in Taiyuan, Yang Gongren has never been in contact with Li Yuan, he is a royal family, and Li Yuan is a rebel, it is difficult for them to have the former friendship.

Yang Gongren pondered for a moment and said, "Please wait for him in the guest room!" ”

He had also heard a little about Li Yuan and Yang Yuanqing's fight for Hedong, but he didn't know the details, after all, it was Hedong, across the Yellow River from him, and all his attention was on Luoyang, so he had no time to look north about Hedong.

Yang Gongren walked to the guest room full of doubts, and as soon as he entered the door, he was stunned, and the person sitting in the room turned out to be Li Jiancheng, the son of Li Yuan.

Li Jiancheng and Yang Gongren are the same generation, the two are very familiar, Li Jiancheng bowed his hand: "Unexpected visit, I hope Brother Gongren will not be surprised." ”

Yang Gongren wondered in his heart, as Li Jiancheng's son, he must have come to visit Lu in person, there must be something important, does Li Yuan want to seek Hongnong County?

Yang Gongren returned the salute quietly and smiled: "It turned out to be a visit from Jiancheng, which is unexpected!" Have a seat! ”

The two sat down, Yang Gongren ordered someone to serve tea again, Li Jiancheng was anxious, but at this time, it was useless to be anxious, he had to restrain his inner worries, and reluctantly smiled: "I heard that the situation in Luoyang is tense, I don't know if the Wagang army has invaded Hongnong County?" ”

Li Jiancheng's concern made Yang Gongren feel very weird, and to some extent, Li Jiancheng was also his enemy, Yang Gongren smiled, "It's okay!" The Wagang army is attacking Luoyang with all its might, and there should be no sign of attacking Hongnong for the time being, and Hongnong County seems to have no major problems at present. ”

Li Jiancheng groaned and said, "Then what are Gong Renhuang's plans in the future?" ”

"Intended?.

Yang Gongren glanced at Li Jiancheng vigilantly and asked, "Jiancheng, are you here to convince me to surrender to Chang'an?" ”

Li Jiancheng shook his head, "I don't have this intention, and my father won't force Brother Gongren, if Brother Gongren is willing to return to Chang'an, of course we welcome it, but I really didn't mean to persuade him to surrender this time." ”

Yang Gongren's heart became more and more strange, and he asked with a smile: "Since you are not here to persuade me, what are you doing?" Do you want your son to come forward in person, aren't you afraid that I will arrest you and send you to Jiangdu? ”

Li Jiancheng also laughed, "I came in person to express my father's sincerity, if Gongren wants to send me to Jiangdu, it can only mean that my father is looking at the wrong person." ”

Of course, Yang Gongren would not send Li Jiancheng to Jiangdu, but he was still very vigilant about Li Jiancheng's arrival, Li Jiancheng's arrival must have a deep intention, and he still asked vigilantly: "Then you just say it!" What is the purpose of you coming to me? ”

Li Jiancheng took out a letter and handed it to Yang Gongren, "This is a handwritten letter from my father to you, you will understand after reading it." ”

Yang Gongren hurriedly read the letter after reading it, and then understood Li Jiancheng's intention, "It turns out that you want to borrow the Tao!" ”

Li Jiancheng nodded, and said with a long sigh: "Shimin is no match for Yang Wuqing in Hedong, and even the back road has been cut off, and now the situation is critical, he can only cross the river to Hongnong County first, and then return to Guanzhong from Hongnong County. ”

"But ......"

Yang Gongren's face showed embarrassment, "If it is the people of the world who lead a hundred people to cross the border, maybe I can hide it, but this is tens of thousands of people crossing the border, and I need to organize a boat, how can you let me explain to the saint?" ”

Li Jiancheng was so anxious that he couldn't hold back any longer, so he said: "Father said, if you really feel embarrassed, then we don't want you to come forward, as long as you close the city gate, all the things that collect ships will be done by us, after taking the people and the army back to Hongnong County, we will return to Guanzhong immediately, and we will not commit any offense to Hongnong County, I don't know what Brother Gongren thinks of this plan?" ”

Yang Gongren couldn't say a word for a long time, Li Jiancheng's meaning was very clear, let him help organize the ships, if he didn't want to, then they would do it themselves, and the army in Guanzhong would take over the Yellow River Nankai, how could this work?

"This ...... Let me think about it. Yang Gongren was very embarrassed, Li Yuan must come, and there was no room for him to refuse.

Yang Gongren pondered for a long time, he was afraid that Li Yuan's army would not leave after entering the country, and it was easy to invite the gods to send the gods, which he knew very well in his heart, rather than their army coming in, it was better to send a favor himself.

He finally nodded, "For the sake of the old friendship, I will help you once this time, I will organize boats to take the people across the river, if the saint is angry, I will bear it." ”

Li Jiancheng was overjoyed, stood up and gave a deep salute, "The situation is urgent, please Brother Gongren deal with it as soon as possible." ”

"Tomorrow morning, I will go to organize the boats, I wonder where the people are going to cross the river?"

"Crossing the river between Hebei County and Shaanxi County."

These six times the army retreated south, Li Shimin completely obeyed Qu Tutong's plan, they steadily retreated south, and on the other hand, they continued to send cavalry to Fenglingjin to collect ships, and put on a posture of preparing to cross the river from Fenglingjin, and their army did retreat in the direction of Fenglingjin.

Because Li Shimin's army did not retreat south in a hurry, the army was neat and orderly, Yang Yuanqing did not rush to chase and kill, but led the army to follow them all the way south, and always followed Li Shimin's army forty miles away Yang Yuanqing's tactics are also very clear, he will not fight against Li Shimin's army, but wait for the fighters that appear when Li Shimin's army crosses the river, and when any army crosses the river, there will be a moment when the defense is weak, and that is when he attacks on a large scale.

In the south of Hedong County is Zhongtiao Mountain, there are two counties in the narrow strip of more than 200 miles south of Zhongtiao Mountain, one is called Ruicheng County, one is Hebei County, Fenglingjin Ferry is in the southwest of Ruicheng County, and Hebei County is in the east of Ruicheng County.

On this night, Li Shimin's army arrived in Ruicheng County, and Yang Yuanqing's army also arrived forty miles north of Ruicheng County and temporarily stationed down without a tent The army rested on the ground, and in the middle of the team, a marching tent was set up, and in the tent, Yang Yuanqing and several generals were discussing the military situation in front of the map.

"I don't know if you feel this way, I don't think Li Shimin is necessarily going to Lingjin." Yang Yuanqing glanced at everyone.

Qin Qiong looked at the map, his brows tightened, he didn't quite agree with Yang Yuanqing's strange feeling, so he said: "But we got the information of the scout, Li Shimin's forward has already collected hundreds of ferries in Fenglingjin, if he doesn't go from here, where will he go?" What about ferries? They should not have much rations. ”

Yang Yuanqing glanced at Li Jing again, "Li Sima, what do you think?" ”

Li Jing groaned and said: "I just think that the other party's retreat to the south this time is very orderly, not in a hurry, not in a hurry, well-organized, without loopholes, it can be said that there is no ...... can be attacked, this is completely different from when Li Shimin went north, Li Shimin was like a spear when he went north, sharp and enterprising, and this time the retreat was like an old monk sitting still, not leaking, I think this is only done by very experienced people, you might as well boldly speculate that this time the southern retreat is presided over by Qu Tutong. ”

Yang Yuanqing nodded, "I feel this way, I sent cavalry to harass and attack the camp at night twice, but they all returned in vain, maybe it was Qu Tutong who was presiding over the southern retreat." ”

Li Jing said again: "If it is really Qu Tutong, then his habit will surprise at the last moment, and it will be unexpected, and he will probably not cross the river in Fenglingjin." ”

Li Jing pointed to Hebei County with a wooden pole, "Do you find anything special about this Wu County?" ”

Everyone's eyes looked at Hebei County together, and Yang Yuanqing blurted out, "This is a pass!" ”

Everyone saw that there were mountains all around, and there was a canyon about several miles wide in the middle of the mountain beam, and Hebei County was built in this canyon, and through the county seat was the river beach ferry.

Li Jing knocked on Hebei County with a wooden pole, "Hold Hebei County, we will not be able to get close to the ferry, I dare to conclude that Qu Tutong will definitely cross the river from Hebei County, as for the ferry, it should be that the other side of the river has been prepared." ”

Yang Yuanqing watched silently for a moment, he knew that he was confused by the illusion that Qu Tutong had deployed in Fenglingdu.

At this moment, a soldier shouted at the door, "The forward spies report urgently, the enemy army has left Ruicheng County and marched eastward." ”

Everyone was taken aback, and sure enough, they didn't go to Fenglingjin, they rushed out of the tent, but Yang Yuanqing shouted: "Don't mess up, all stop!" ”

Everyone stopped, and Yang Yuanqing asked, "How did you march?" ”

"Report to the Chief, the spies said that the enemy army is moving very slowly, and they are marching in formation."

Yang Yuanqing looked at the pass in Hebei County in a daze, and sighed for a while, "As the saying goes, it is up to people to make things happen, and success is in heaven, God arranged this pass, and it is destined for Li Shimin's army to escape." ”

Su Dingfang said on the side: "Governor, I am willing to lead the cavalry to bypass the enemy army and occupy Hebei County first." ”

Yang Yuanqing shook his head, "We only thought of Hebei County now, but Qu Tutong thought of it in Linfen County, he should have already been deployed, and there was no need to go again." ”

In late August of the twelfth year of the Great Cause, Li Shimin led 90,000 troops to cross the Yellow River from the ferry port of Hebei County and fled south, and Qu Tutong personally led 10,000 troops to hold Hebei County, blocking the 60,000 pursuers of the Fengzhou Army from the pass.

Three days later, Qu Tutong was attacked by the Fengzhou army when he led the rest of the army to cross the river, 10,000 troops who crossed the river were killed and wounded and surrendered more than 7,000 people, Qu Tutong only led more than 2,000 people to cross the river to escape, so far, a battle of Hedong that lasted for more than two months finally came to an end.
