In the next few days, the two sides called each other for battle, but Hei Batian did not come out, and Ban Chao had nothing to do, and the two sides had been holding each other for more than a month.

Hei Batian summoned Douti, Jin Tu, and Fanjia to discuss: "King Shache came to report that Kunlun Xiao led the Han army and the Khotanese army to attack Shache, so the Shache soldiers could not come to help for a while. Kudelu and King Qiuzi led an army of 20,000 to attack Gumo but did not take it, to repel Banchao's army only rely on the Kangju army, I am ready to go to Kangju in person, send a generous gift, and persuade the king of Kangju to lead a large army to help. The king led General Jin Tu and General Fanjia to defend the city, Artush Chi was strong, Banchao's army was only a few thousand, neither dared to divide the troops to besiege the city, and did not dare to attack, as long as the king could not hold out, the Han army would be tired for a long time, and I led the Kangju army to arrive, and the two sides would attack and destroy Banchao. Everyone thought so, and Hei Batian packed up a lot of money and led dozens of horsemen to open the west gate.

However, it was said that the Black Detian general Hu Delu led his troops to station at the border of Qiuci and received the order of Hei Batian, that is, he led 5,000 troops to meet the King of Qiuci. Bai Mi, the king of Qiuzi, ordered his younger brother Bai Tu to lead Wuli Hu and Wuli Xiong to lead an army of 15,000 people to join Kudelu, who was commanded by Kudelu. This Hudlu is a black overlord general, with infinite power and a lot of military aircraft. The previous time he and Zuo Xianwang were defeated by Ban Chao in the car division, and they were not convinced. This time, the black tyrant Tiance opposed Shache and the king of Shule, bought Kangju, and then joined the Qiuzi army to attack Shule and clear the Han army in the Western Regions. Then unite the armies of various countries to defeat Khotan and Shanshan, and reoccupy the Western Regions to remove the threat of the black overlord's flank. Hei Batian was convinced of this strategy, and in order to deal with Hei Batian, he specially ordered Hu Delu to lead 5,000 elite soldiers to garrison the border of Qiuzi, and ordered Hu Delu to accept Hei Batian's moderation.

Kudelu received an order to join the Qiuzi army and besiege the city of Gumo Wang. Seeing that the enemy army was strong, Huangfu Wuji, the king of Gumo, took advantage of the enemy's unstable foothold and led 3,000 elite soldiers to break through the encirclement at night and go straight to Bachu City. Suddenly, the law soldiers occupied the Gumo King City without blood, and they were overjoyed, and they sent fast horses to Artush to report: Capture the Gumo King City in a war, and soon march into Bachu City to eliminate Huangfu Wuji, so as to attack Banchao together; On the one hand, a banquet was held to entertain the generals.

Hu Delu said: "As soon as the army arrives at Huangfu Wuji and flees without a fight, please Lord Bai Tu lead 5,000 troops to garrison the royal city, and I will lead 15,000 troops to besiege Bachu City." Bai Tu said: "I will hold this city, the general can rest assured." I heard that Bachu City is easy to defend and difficult to attack, and the defender Liu Rui is both wise and brave, and the general should not be careless. Hu Delu said: "I have fought with him in the chariot division, although he is good at fighting, but the remnants of the United Emperor Fu Wuji are only 3,000 people, and our army is five times that of him, this time he will not escape." Hu Delu's subordinate Yongyan said: "I'm afraid he ran away overnight." The crowd laughed.

Liu Rui was patrolling the city, and when he saw Huangfu Wuji leading his army in the middle of the night, he hurriedly opened the city to greet him. Huangfu Wuji said: "Bai Tu, the younger brother of the king of Qiuzi, and the general of the black tyrant, Hu Delu, led an army of 20,000 to surround the royal city, and I took advantage of his unstable foothold to rush out of the encirclement overnight to meet the general." Liu Rui said: "It's good to rush out, Bachu City is now full of soldiers and food, and there is no problem in guarding him for half a year." Kudelu easily captured the royal city, and tomorrow he will definitely come to besiege the city of Bachu, and we will hold him back, so that he will not be able to reinforce Kashgar. Huangfu Wuji nodded.

In the afternoon of the next day, Khudelu led the army to the city of Bachu. Wan Yan said domineeringly: "General, in order to prevent the enemy from escaping, we will besiege this city overnight." Hu Delu said: "Our army is tired after a day of running, Liu Rui is a general under Ban Chao, he must know the strategy, if I divide the army to surround me on all sides overnight, and concentrate his forces to attack my side, our army will be defeated." Ten miles away from the city today, and tomorrow the city will be besieged and attacked from all sides. Wan Yan said domineeringly: "The general is thoughtful and does not admire." ”

Liu Rui saw that Suddenly Delu did not come to besiege the city, and he camped ten miles away from the city, so he said to Huangfu Wuji: "This Sudden Law is quite aware of military aircraft, and he will come to besiege the city tomorrow when he is ten miles away from the city." Suddenly, I knew that I would attack him if I had few soldiers, and I would not be in a hurry to attack him tonight. Huangfu Wuji nodded and said: "Because of the lack of water in the royal city, it is not easy to hold on to it, and I will abandon it, and tonight's heavy damage to the enemy army will also make the enemy dare not underestimate my Gumo soldiers." Liu Rui said: "Please Liang Guoxiang defend the city, we each lead a thousand men and horses, you attack the enemy camp from the front, you have to make a big fanfare, set fire to the enemy, I led a thousand fine cavalry around the back of the camp, after seeing the fire, kill from behind, and hit the enemy hard, but the enemy is numerous, can not go deep, can not fight, and withdraw in time while the enemy has not slowed down." After attacking the enemy, I went around to the south gate and entered the city. The two of them had decided to go their separate ways to prepare.

Liu Rui led the army out of the city for half an hour, and Huangfu Wuji also led the army out of the city. Approaching the enemy tent, found by the sentry, Huangfu Wuji ordered the army to beat the drum and shout, Huangfu Wuji held the mountain axe, rushed into the enemy camp first, and hacked the sentry to death with the axe, the army saw that the king was brave, and the morale was greatly boosted, and rushed into the enemy camp to take advantage of the situation to set fire, and the enemy camp was in chaos.

Hu Delu had just fallen asleep and heard the Han soldiers robbing the camp, hurriedly got up and put on his horse, stood in the middle of the camp with a spear in his hand, and ordered the troops to resist on the spot, not allowed to run around, a few chaotic soldiers shouted that the enemy army robbed the camp and ran by, and was stabbed several people by Hu Delu with a gun, and the rest of the people did not dare to run around when they saw this, and turned back to resist. Suddenly, Lu summoned Wan Yan Ba and Wan Yan Shou and said: "You two quickly attack from both sides, the enemy army is bluffing, the number is small, surround them and destroy them." The second general ordered to leave.
