When the Qin army and the Huns were fighting at the border pass, something happened in the palace of King Zhao in Hebei: it turned out that King Wuchen of Zhao was giving the general Li Liang a beautiful wine and beauty, so that he could enjoy the wealth of life. Li Liang was originally a womanizer, and when he saw that King Zhao rewarded him a lot, he spent all day drinking and drinking, so he was uncomfortable. But one day, the more his subordinates Xue Yue and Zhang Qiang thought about it, the more wrong they became, so they came to see Li Liang. Li Liang saw that he was a favorite general under his command, so he happily treated him with good wine and meat, and then drank happily and talked about everything.

After a few rounds of drinking, Xue Yue and Zhang Qiang said to Li Liang: "General, now the world is full of heroes, and everyone is vying to make meritorious contributions, but why do you only want to be rich and expensive in front of you?" Li Liang asked strangely: "I pacified Hengshan County, King Zhao named me the imperial history, and then gave me fine wine and food, beautiful concubines, this day is simply comfortable to die, how can you say that you are rich and noble?" Xue Yue disagreed, and said: "General, you just got an imperial history, and you are just an idle position, why aren't you a little rich and noble?" When Li Liang heard this, he asked what kind of wealth and nobility are considered to be rich. Xue Yue said in a very spirited tone: "If you enter, you will enjoy the respect of ten thousand times, if you go out, you will control the people of ten thousand people, if you are profitable, you will make ten thousand people humble, and after the name is shown for eternity, such a prominent person can be regarded as rich and noble!" When Li Liang heard this, he lowered his head and drank in embarrassment. Xue Yue continued: "I heard that King Zhao is jealous of his talents, and he hates his subordinates the most. Li Liang was puzzled, so he asked how to say this. Xue Yue said: "In the past, the king sent Han Guang to attack Yan Land, and after Han Guang seized the land, he established himself as the King of Yan. And your merits are comparable to those of King Yan, but there is a world of difference between you and him! Think about it, King Zhao only asked you to make an imperial history, isn't this a suspicious general? When Li Liang heard this, he suddenly realized, and he overturned the case and said angrily: "This is indeed the case!" Who will compete with me in the land of Yan and Zhao! Xue and Zhang were shocked, and hurriedly knelt down and said, "We are talking nonsense after drinking, please forgive the general?" Li Liang laughed and walked over to help the two of them up, saying, "It's not that you two say it, I'm still in the dark." Tomorrow I will go to the king to ask for a soldier and horse, and I will re-conquer the field and make another contribution! How can a husband mess with girls all day long? Xue and Zhang were overjoyed and said: "If the general can regain control of the army, I am willing to serve the dogs and horses!" Li Liang laughed comfortably.

The next day, Li Liang really entered the palace to meet King Zhao. When King Zhao saw Li Liang coming, he asked, "What is Qinglai's business?" Li Liang replied: "King, now all the heroes and heroes of the world have raised troops against Qin, I heard that the Qin State sent a man named Zhang Han to lead the army out of the pass, and the Chu army was defeated and retreated. I once heard of Zhang Han, he is just a general in Lishan, who is in charge of the military affairs of Daling, and he is unknown! Please give me a soldier and horse, and I will kill Zhang Han, raise my prestige for the world, and expand the territory for Zhao! King Zhao suddenly remembered Kui Che's words, so he prevaricated a few words, and did not agree to Li Liang's request. Li Liang insisted on asking for help. King Zhao had no choice, so he said frankly: "Lone originally wanted to reuse Qing, but Qing is the general of Qin, even if Lone trusts it, how can he block other people's mouths?" As soon as Li Liang heard this, he must have said something bad about others, so he took off the golden crown, hit his head on the ground, and blood came out of his forehead, and then said resolutely and sincerely: "Since I surrendered to the king, I have often been grateful for your kindness, even if my liver and brain are ruined, I can't repay you one ten-thousandth of it!" Why should the king be suspicious of his ministers? Although the minister is a general of the Qin State, the Qin law is very strict, you know this. The minister has already descended to the Zhao State, and there is no way out for a long time, how dare he have two hearts? Would the king please observe the sincerity of his ministers? Now I just ask the king to give the minister a soldier and horse, and the minister will work hard to serve the king, although he will die without regrets? ”

King Zhao was moved by Li Liang's words, so he got up and walked down the steps, helped Li Liang up, and said, "Gu has long known that Qing is a loyal and righteous person. Now there is an opportunity to make contributions, you must seize the opportunity and don't let down Lonely! Li Liang said excitedly: "Please command the king, the minister will not give up!" King Zhao said: "Qing captured Hengshan County before, do you know that there is a well pass in the west of Hengshan County?" Li Liang said that he knew. King Zhao said: "This pass is the throat of Hebei Sichuan into the mountains of Hedong, recently Tanma report, I heard that Qin is going to send Wang Li out of the pass to attack our country. Qing Ke led 30,000 elite soldiers, immediately rushed to Hengshan, called all the soldiers and horses of Hengshan, and then captured Jingcheng Pass. Don't wait for Wang Li to leave the pass, you go into the pass first, and because the Huns often commit border crimes, it is impossible for Wang Li to go out of the pass easily without taking care of the Huns. If Zhao can get the Hedong Prefectures, then Zhao's territory will expand several times, and Qing's merits will exceed all the generals, this is a good opportunity to make contributions, I hope Qing must grasp it! Li Liang was overjoyed and thanked him repeatedly. King Zhao gave the general seal to Li Liang. Li Liang happily accepted the task and bid farewell to King Zhao. Li Liang went out of the palace gate, afraid that King Zhao would regret it, so he immediately ordered the elite soldiers, took Xue Yue, Zhang Qiang and other ordinary old generals, and quickly left Handan City and galloped to the north.

When Prime Minister Zhang Er heard about this, he immediately rushed to the palace and said to King Zhao: "King, Li Liang is fierce by nature, violent and unplanned, how can he give the right to the army again?" Besides, he is a general, if he turns against him, it will be difficult for the king to control him, who made the idea for the king? This man should be killed! King Zhao straightened his face and said: "It's Lonely, no one speaks for him, Lone only knows that there is no suspicion in employing people, and no suspicion is needed." Don't say any more! Zhang Er saw that King Zhao had made up his mind, so he continued: "The king reuses fierce and unrighteous people, I am afraid that it will cause endless disasters!" King Zhao said: "Li Liang is a loyal and brave man, why is there a disaster?" Please don't be suspicious of others, please do your job well! Zhang Er saw that he was bored, so he had to retreat. When he came to the Prime Minister's Mansion, he sighed to the people around him and said, "If the king doesn't listen to his advice, I'm afraid our good days will come to an end!" ”

Li Liang led 30,000 Zhao troops to Hengshan County, and then called all the soldiers and horses here, there were tens of thousands of people. Li Liang led them to the front of Jingcheng Pass, preparing to attack the pass. Jingcheng Pass, to pass the name, that is, Jingchengkou, also known as Tumen Pass, one of the famous Taihang Eight Gates. This is an important pass for Taihang Mountain to enter the North China Plain, and Jingcheng is a pass in Taihang Mountain, so the terrain here is very dangerous, it is really easy to defend and difficult to attack. From 229 to 228 BC, the Qin general Wang Jian broke through the Zhao army from this pass, thus capturing Handan City and destroying the Zhao State in one fell swoop. Now Li Liang has formed a formation at the foot of the mountain, preparing to take Xiongguan, so he sent the vanguard to attack Xue Yue and Zhang Qiang.

Qin's Guan Du Lieutenant's name was Du Yu, who was in the prime of life and was a loyal and brave general, and when he saw the Zhao army coming to seize the pass, he came to the Guan to oversee the attack. Because the road to this pass was very narrow, the Zhao army attacked for three days in a row, but did not reach the pass. Seeing this, Li Liang was very angry, so he personally went to battle. After he led the Zhao army to rush to the pass, he loudly insulted Du Yu and challenged him vigorously. Du Yu knew that Li Liang was originally a general of the Qin State, and now he had surrendered to the military ministers, so he came to the gate angrily and scolded Li Liangdao: "You were originally a general of the Qin State, but now you have surrendered to the thief, you are really a dog who shouts your mother when you see milk!" What other face to challenge? Is it really a lackey of the anti-thief? Li Liang was so angry that he didn't say anything, just screamed out and died. Du Yu is about to fight. Deputy Commander Song Yan persuaded: "General don't worry, although Li Liang is an unrighteous person, he is also known as the 'Hebei Tiger', and because he has just won and his morale is booming, it is better for us to stick to it, and we have already reported to the imperial court, and soon Wang Li will come to reinforcements." At that time, if you go out of the customs and fight, you will definitely be able to break Li Liang. Du Yu said: "It's far away from the north, when will the reinforcements arrive?" Traitors are in the realm, and the battle is imminent, so there is no room for fighting? I'll go out and fight that bastard first, and if I die in battle, you'll just hold on and wait for help, right? So he mounted his horse with his spear and rushed down the gate.

Du Yu came to the front of the pass, stood up, raised his whip and pointed at Li Liang and scolded: "Li Liang, as a member of the Qin State, why did you betray the country?" Li Liang smiled and said: "The second is a bastard, and he can't govern the country, the Qin State will be finished sooner or later, how can my dignified husband serve a bastard?" Now I just want to enter the pass, take his bird position, I will be the emperor, and then make you a general, what do you think? Du Yu said angrily: "Betraying the Lord for glory, shameless guy, you are really daydreaming." I'll cut off your dog's head first! "Let's shoot the horse to kill Li Liang. Li Liang greeted him very contemptuously.

The two fought for forty or fifty rounds in front of the pass, and Du Yu couldn't parry, so he made a false move, turned around and left. Li Liang chased after him, and saw that Du Yu was about to enter the customs, so he ruthlessly took out his halberd, which was not biased or oblique, and just stabbed Du Yu in the back, and Du Yu fell from his horse and died on the spot. When Zhao Jun saw that General Qin was dead, he shouted and came to rush the pass. Song Yan hurriedly ordered the door to be closed. Li Liang turned back to Zhao Jun and shouted: "Whoever breaks through the pass first will be rewarded with 1,000 taels of gold, and the head of a thousand households will be sealed, and those who retreat will be killed!" When Zhao Jun heard the order, he took the lead and rushed to close the door. Song Yan hurriedly ordered the wood and cannon stones to be thrown down together, and he also shot arrows violently. Seeing this, Li Liang had no choice but to withdraw the sergeant again. Song Yan then snatched Du Yu's body to the pass, then held on, and then sent a fast horse to report to Wang Li.
