Emperor Dezong had Li assume the command of Jingyuan Circuit as well as Binning Circuit and moved his command to Jingyuan's capital Yuan Prefecture (原州). The Jingyuan soldiers feared Li's reputed harshness, particularly given his execution of the five Binning officers in 779.

, Ma believed that they should wait and rest their soldiers before attacking, but Li Huaiguang advocated an immediate attack, and did so. He initially had successes against Zhu, but Wang took the opportunity to charge against his troops, cutting them off from each other, and eventually the imperial forces were routed. They were forced to lift their siege of Weibo's capital Wei Prefecture (魏州), but held their position in stalemate against the rebel forces. Emperor Dezong gave Li Huaiguang the honorary chancellor designation of Tong Zhongshu Menxia Pingzhangshi (同中書門下平章事). Subsequently, in light of their victory, the rebel leaders all declared themselves princes independent from Tang.

, JIngyuan soldiers, then at Chang'an to be ready for deployment against the rebels in the east, mutinied when they were angry they did not get rewards. Emperor Dezong was forced to flee to Fengtian (奉天, in modern Xianyang), while the Jingyuan soldiers supported Zhu Ci as their leader, and Zhu Ci soon declared himself emperor of a new state of Qin. Upon the news arriving in the imperial camp at Wei Prefecture, Ma, Li Baozhen, and Li Qiu (李艽) withdrew to their own circuits, while Li Huaiguang, under the suggestion of his logistics officer Cui Zong (崔縱), decided to march as quickly as he could toward Chang'an to save Emperor Dezong. By the time that Li Huaiguang arrived in Chang'an's vicinity, Fengtian was under intense siege by Qin troops under Zhu Ci. Li Huaiguang sent his officer Zhang Shao (張韶) to Fengtian to inform Emperor Dezong of his impending arrival, and then attacked Qin forces at Liquan (醴泉, in modern Xianyang) and defeated them. When Zhu Ci heard the news, he, in fear, lifted the siege on Fengtian and withdrew back to Chang'an. It was believed at the time that Li Huaiguang arrived right on time and that, if he were even three days late, Fengtian would have fallen. After the victory, Emperor Dezong gave Li Huaiguang the title of Zhongshu Ling (中書令) — the head of the legislative bureau of government (中書省, Zhongshu Sheng) and a post considered one for a chancellor.

Meanwhile, though, it had become common knowledge that Li Huaiguang despised several officials that Emperor Dezong trusted — the chancellor Lu Qi

 and other ministers Zhao Zan (趙贊) and Bai Zhizhen (白志貞) — and that he would recommend to Emperor Dezong that those officials be removed. When Lu heard this, he believed that he had to prevent a meeting between Emperor Dezong and Li Huaiguang at all costs, and therefore suggested to Emperor Dezong order Li Huaiguang to attack Chang'an at once. Emperor Dezong agreed, and ordered Li Huaiguang to rendezvous with Li Sheng

, Li Jianhui (李建徽), and Yang Huiyuan (楊惠元) to attack Chang'an. Li Huaiguang, angry that he was not even able to meet the emperor, began to resent Emperor Dezong. He stopped his army's movement and submitted petitions accusing Lu and the others of crimes and further accusing them of being responsible for the Jingyuan mutiny. Emperor Dezong was forced to demote and exile Lu, Bai, and Zhao. Li Huaiguang also submitted a petition accusing Zhai Wenxiu of crimes, and Emperor Dezong executed Zhai in response. Only after these events occurred did Li Huaiguang rendezvous with Li Sheng, Li Jianhui, and Yang, in spring 784

. Meanwhile, when Emperor Dezong sought aid from Tufan, Tufan's chancellor Shang Jiezan (尚結贊) refused to launch forces unless he could get an explicit cosigning of the aid request by Li Huaiguang, citing Tufan's own laws about how it would only launch troops in aid if the supreme commander of the state seeking aid also agreed with the aid request. Li Huaiguang was vehemently against seeking Tufan aid, however, citing how Tufan troops would surely pillage the region and also seek excessive rewards, and he refused to cosign the aid request, and Shang refused to launch aid troops. Emperor Dezong's trusted advisor Lu Zhi

, believing Li Huaiguang to be on the verge of rebellion and fearing that Li Huaiguang would take over the troops under Li Sheng, Li Jianhui, and Yang, urged that those three armies be separated from Li Huaiguang's army and take up position elsewhere; Emperor Dezong repositioned Li Sheng, but believing that relocating Li Jianhui and Yang as well would bring further resentment from Li Huaiguang, did not move them.

Li Huaiguang, indeed, was then in secret communication with Zhu Ci and considering rebellion. Zhu promised Li Huaiguang that he would be willing to divide the realm into two, with both serving as emperors, and would be willing to honor Li Huaiguang like an older brother. Meanwhile, Li Sheng, believing Li Huaiguang to be ready to rebel, requested that precautions be made and that the road to the Hanzhong

) regions be clear, in case of a Li Huaiguang rebellion. Emperor Dezong hesitated, and instead announced that he would go to Xianyang (咸陽, in modern Xianyang) to monitor the advancement of troops. Li Huaiguang, believing that the announcement was against him, further prepared for rebellion. Emperor Dezong, meanwhile, tried to calm Li Huaiguang by sending the official Li Bian (李卞) to award him with the title of Taiwei (太尉, one of the Three Excellencies
Three Excellencies

) and an iron certificate (鐵劵, Tiejuan), which promised that he would never be executed. Li Huaiguang, believing that these were actually signs of distrust, threw the iron certificate onto the ground and stated:
When Li Bian returned to Fengtian and informed Emperor Dezong of these events, the officials at court began to prepare to evaluate Fengtian if necessary. Soon thereafter, Li Huaiguang made a surprise attack on Li Jianhui and Yang; Li Jianhui barely escaped with his life, while Yang was killed. Li Huaiguang thereafter made a declaration:
On March 21, 784, with Li Huaiguang's declaration and posture of readiness to attack Fengtian, Emperor Dezong fled to Liang Prefecture (梁州, in modern Hanzhong).

As rebel against Emperor Dezong

Li Huaiguang sent his officers Meng Bao (孟保), Hui Jingshou (惠靜壽), and Sun Fuda (孫福達) to chase after Emperor Dezong, but the three, not wanting to track down the emperor, intentionally slowed down, allowing Emperor Dezong to flee. Meanwhile, Li Sheng took a defensive posture and also wrote Li Huaiguang letters trying to persuade him to return to the imperial cause; while Li Huaiguang did not do so, he was sufficiently embarrassed and concerned that his soldiers would turn against him in an attack against Li Sheng that he did not attack Li Sheng. Meanwhile, a number of his subordinates, including Han Yougui (韓遊瓌), turned against him, weakening his army. As a result, Zhu Ci stopped treating him as an equal and instead was sending him edicts. His subordinate Li Jinglüe (李景略) tried to persuade him to attack Zhu Ci and resubmit to Tang, but under the suggestion of Yan Yan (閻晏), he decided to instead withdraw from the Chang'an region to Hezhong.

After Li Huaiguang's departure for Hezhong, Emperor Dezong issued an edict declaring his guilt, but also recounting his accomplishments and offering him the title of senior advisor to Emperor Dezong's son, Li Song

 the Crown Prince, but otherwise stripping him of his posts. The edict further offered Li Huaiguang's Shuofang army the option of deciding their next commander. The edict appeared to draw no reaction from Li Huaiguang.

In fall 784, after Li Sheng had destroyed Zhu's regime (which Zhu had renamed Han) and recaptured Chang'an, allowing Emperor Dezong to return to Chang'an, the imperial eunuch messenger Yin Yuanzhen (尹元貞) was able to persuade Li Huaiguang to resubmit to Emperor Dezong. He sent his son Li Wei to Chang'an to beg Emperor Dezong's forgiveness. Emperor Dezong thereafter sent the official Kong Chaofu (孔巢父) to Hezhong to accept his resubmission. When Kong arrived, Li Huaiguang changed into civilian clothing to show meekness and remorse, but Kong did not tell him to change back into official uniform. When Kong further asked the soldiers, "Who can succeed the Taiwei in commanding this army?" the soldiers were incensed, and they rushed and killed Kong and the eunuch Dan Shouying (啖守盈), with no intercession from Li Huaiguang, and Li Huaiguang thereafter again took a posture against the imperial troops. Emperor Dezong sent Hun Zhen and Luo Yuanguang (駱元光) against Li Huaiguang, but they were stopped by Li Huaiguang's officer Xu Tingguang (徐庭光) at Changchun Palace (長春宮, in modern Weinan) and unable to advance. Meanwhile, though, Ma Sui was attacking Li Huaiguang's territory from the north and east and seizing Li Huaiguang's territory piece by piece.

 and Li Yong, under arrest for associating with Lü. Meanwhile, Ma rendezvoused with Hun at Changchun Palace and put it under siege. By this point, the Shuofang soldiers were largely ready to turn against Li Huaiguang, and when Yan Yan tried to lead them against Han Yougui's Binning army — which was branched off the Shuofang army, and whose soldiers therefore mostly had family relationships with the Shuofang soldiers — the Shuofang soldiers refused to fight against Binning soldiers. Li Huaiguang declared to the soldiers that he was ready to resubmit to Tang and offer tributes to Emperor Dezong, but thereafter did nothing for another month.
