It is undeniable that the loss of Luoyu Pass made Dong Zhuo very passive, but everyone knows very well about the passage of Fu Luo Road, Liu Zhang's hundreds of thousands of troops cannot be crossed quickly, and now there is still time for Dong Zhuo to transfer troops and generals, and arrange the defense line around Wugong, as long as Wugong is held, Liu Zhang's army can still be blocked in a corner. The most important thing is that it is necessary to immediately send reinforcements to Wugong and the entire Qinling defense line, because Li Ru judged that Liu Zhang saw that the Luoyu Pass was conquered, Dong Zhuo would inevitably redeploy his troops to guard against Wugong, and it was likely that he would ignore the defense of Meridian, Bao Xian, and Chen Cangdao, Liu Zhang could not let go of this opportunity, and it was very likely that he would send troops to break through one of the meridians, Bao Xian, and Chen Cangdao.

Dong Zhuo regained his composure after losing his temper, and he was convinced of Li Ru's judgment, but Chang'an had no troops to send to defeat, so he had no choice but to transfer 10,000 troops from Hangu Pass, and Ziwu and Baoxian each transferred 5,000 troops to go to the martial arts to assist in defense. In order to facilitate the command, Dong Zhuo ordered the Zhendong general Zhang Ji to fight the Weishui defense line, all the soldiers and horses are subject to its control, if there is disobedience, Zhang Ji has the right to cut first and then play (originally it should be Yang Feng, but Yang Feng's prestige is insufficient, and all the generals under his command are against his yang and yin, Li Ru is worried that Yang Feng will be difficult to control the overall situation, after all, Li Le's overstepping report incident occurred not long ago, so he said to Dong Zhuo that Zhang Ji, the general of Xiliangsu who is as famous as Li Dao and Guo Yan, will take the position of Yang Feng's deputy to the Weishui war, and Yang Feng is still in the name of commander-in-chief, However, he was ordered to sit in Yixian, and was actually deprived of the right to command. These forces were not enough to stop Liu Zhang's hundreds of thousands of troops, and if he wanted to drive Liu Zhang back to Hanzhong, Dong Zhuo had to rely on the 150,000 troops in the hands of Li Dao and Guo Yan in the northwest. As early as after learning that Liu Zhang had the intention of the Northern Expedition, Dong Zhuo gave strict orders to Li Dao and Guo Yan, telling them to end the Northwest War as soon as possible and transfer the main force back to the north of the Qinling Mountains. Now that the Luoyu Pass has fallen, Dong Zhuo has issued three orders in a day, strictly ordering the two to solve the remnants of Ma Teng and Han Sui within half a month.

Half a month ago, Li Dao and Guo Yan received Dong Zhuo's order to end the battle against Ma Teng and Han Sui as soon as possible, and the two also knew that once Liu Zhang stepped into the pass, the end of the Xiliang Army would come. The Ma clan has been operating in Guzang for decades, and their prestige is extremely heavy, and after retreating to Guzang, Ma Teng called on the people in the city to participate in the defense, and the response was like a cloud. The environment of Wuwei is harsh, the people are fierce, these people go to the city to defend, and their combat effectiveness is not weak ordinary soldiers. Ma Teng knew that it was a matter of life and death, and called on everyone to fight against the water, Ma Teng was even willing to take risks, personally landed in the city, killed several enemies, and greatly boosted his morale, plus Ma Teng's son Ma Chao, the general Pang De, and Han Sui's son-in-law Yan Xing, etc., were all tiger and wolf generals, and repelled Li Dao and Guo Yan several times, killing and wounding more than 20,000 people Li Dao and Guo Yan, of course, Ma Teng and Han Sui also paid almost the same price.

Li Dao and Guo Yan, who fought hard to no avail, received three orders from Dong Zhuo in succession on this day, ordering them to end the battle of Wuwei within half a month and return to the division to defend the Qinling defense line. Dong Zhuo is definitely not a threat, because there are three execution orders along with the order, one partial general, and two lieutenants were beheaded by Dong Zhuo's order because of their negative combat, and their heads were shown to the whole army to set an example. Li Dao and Guo Yan did not dare to slack off, and hurriedly raised their accounts to summon generals to discuss strategies to break the enemy. Li Dao, Guo Yan and others are worthy of being battle-hardened people, and they are well versed in the art of war and strategy, and under Dong Zhuo's strict order to "postpone the killing", they quickly came up with a clever plan: discord! Everyone gathered firewood and the flame was high, and everyone said a word to me, and soon perfected this divisive plan.

Ma Teng and Han Sui are full of contradictions, and Han Sui has even more hatred for Ma Teng to kill his wife, because the interests of the two have to be temporarily combined together, in fact, the fear and vigilance between the two have not diminished for a day, which gives him Li Dao and Guo Yan excellent conditions for their plans. As a result, Li Dao and Guo Yan stopped the attack on the west gate and south gate garrisoned by Han Sui's army, focusing on attacking the north gate and east gate garrisoned by Ma Teng, and at the same time let the inner Ying who was placed in the city spread rumors, saying that Han Sui had a plan to get rid of Ma Teng and gather the strength of the two armies to compromise with Dong Zhuo, once Han Sui annexed Ma Teng's department, the number of troops would reach tens of thousands, even if he surrendered, Dong Zhuo had to be appeased, because Liu Zhang in Yizhou was aggressive, Dong Zhuo did not have much time, energy and troops to waste in the northwest.

Previously, Han Sui had proposed to surrender to Dong Zhuo several times, but it was only shelved because of Ma Teng's strong opposition, and there were rumors that since Han Sui left the base camp Jincheng and fled to Wuwei, because he lost the foundation of his rule, the military salary, grain and grass all relied on Ma Teng to help, and Ma Teng often used the excuse of insufficient food and salary to deduct Han Sui's part, which also caused Ma Teng's army to eat and drink spicy food, but Han Suijun often had no stomach. And Ma Teng, in order to prevent Han Sui from taking the lead, completely cut off Han Sui's military supply, and Han Sui's army can be said to be one less than one. Ma Teng knew these situations, and he also knew that Han Sui had a deep grudge against him, so the rumors were together, and he was immediately convinced, and at this time, a young general of Ma Tengjun who was bought by Dong Zhuojun reported to Han Sui that Dong Zhuo's offensive was fierce, and Ma Teng couldn't parry, so he asked Han Sui to send troops to support. Although Han Sui had the heart to surrender to Dong Zhuo, he only shelved it because he did not reach a consensus with Ma Teng, and now the two armies are still friends looking for food in the same bowl, plus Li Dao and Guo Yan have not attacked his defense area in the past few days, his strength is particularly strong, so he sent 3,000 people to support Ma Teng. However, the passage of this support army through the rumored city of Guzang is undoubtedly something that is easy to reminisce. Soon, Han Sui's reinforcements were rumored to be Han Sui's desire to cooperate with Li Dao and Guo Yan to eliminate Ma Teng with one blow. Ma Chao, whose mother died tragically in the hands of Han Sui, couldn't bear it anymore, and left angrily, personally leading two thousand elite horsemen to meet Han Sui. The two armies met in the city, and Ma Chao, who was full of anger, was bent on avenging his mother and killing the master Han Sui, a capricious villain in his eyes, and did not give Han Sui a chance to explain at all, and the command post department rushed up. Han Sui is not a person who likes to endure humiliation and burden, seeing that Ma Chao attacked for no reason, he explained two sentences at first, but the battlefield shouts shook the sky, and his explanation could not reach Ma Chao's ears at all (even if he heard it, Ma Chao might not necessarily believe it), Han Sui saw that Ma Chao, a junior boy, was so rude, did not listen to the advice, and also commanded the troops to kill him. A civil war broke out in the city of Guzang. Han Sui's son-in-law heard that Han Sui was attacked by Ma Chao, and immediately raised troops to rescue Han Sui, on the other hand, Ma Teng was worried that Ma Chao was missing, and also commanded soldiers and horses to meet Ma Chao, the scale of the civil war escalated rapidly with the arrival of Ma Teng and Yan Xing, and the war instantly implicated the entire city, and many innocent people unfortunately died under the knives of both sides. After Li Dao and Guo Yan sat back and watched Ma Teng and Han Sui fight for most of the day, they ordered to attack Guzang from all sides. After most of the civil war, Ma Teng and Han Sui suffered heavy losses, and they couldn't withstand the attack of Dong Zhuojun's army at all, not to mention that almost all the troops defending the city participated in the civil war, and the city's defense was greatly reduced, and they couldn't stop the onslaught of 100,000 elites of Li Dao and Guo Yan at all. In less than an hour, Guzang City was broken, and Dong Zhuojun swarmed in. Han Sui had been killed by Ma Chao and Pang De before, and Han Sui's son-in-law Yan Xing also killed Ma Teng's second son Ma Xiu. Ma Teng, Ma Chao and his son saw that they couldn't do anything, so they gathered 6,000 people from the tragic department and broke through from the north gate. On the way, Ma Teng left to cover Ma Chao, led his troops to break off, fought to the last man, and finally fell under Li Wei's arrows, and Ma Teng died with his third son Ma Tie. Ma Chao fought Gu Zang under the desperate protection of Pang De and Ma Dai, and led less than 3,000 remnants to run away in a hurry.

Li Dao and Guo Yan followed the decision already made by Cong Dong Zhuo, and set up a banquet to ambush Yan Xing and other horses, and Han surrendered generals, so that they could get their troops. Then Duan Xuan was the Taishou of Wuwei, commanding 10,000 infantry and 5,000 cavalry to guard Wuwei to guard against Ma Chao's attack. Li Dao and Guo Yan led 110,000 troops to aid the Qinling defense line.

Almost when Li Dao and Guo Yan received Dong Zhuo's order to capture Wuwei within a time limit, Liu Zhang learned that the Luoyu Pass had changed hands overnight, and he couldn't help but be overjoyed, and immediately ordered the commander of the Fourth Division to attack the capital department, the commander of the fifth division Hou Chengbu, the first division of the Huwei Division, the commander of the Fifth Independent Infantry Brigade Yang Renbu, the commander of the Sixth Brigade Wu Banbu, the commander of the First Cavalry Division Hua Xiongbu, the division directly under the Fourth Army Corps, and 30,000 soldiers and civilians who crossed the Qinling Mountains by themselves, and he himself also led a group of strategists to advance with the army.

After thirteen days of arduous trekking, Liu Zhang finally walked out of the more than 400 miles of Fu Luo Road, in order to show his determination to live and die with the soldiers, and share weal and woe, he did not rest at the Luoyu Pass, leaving Zhang Zhongjing Gao apprentice Qin Ye in the pass to take care of Xi Zhicai, who fell ill due to the long journey, he went to the south bank of Weishui without stopping.

After settling the soldiers and horses, Liu Zhang immediately summoned the generals to discuss the military situation.
