When Cao Cao laid siege to Xuzhou, Tao Qian, the governor of Xuzhou, invited Liu, Guan and Zhang to relieve the siege, deploring Cao Cao's evil deeds of holding the son of heaven hostage to his vassals and treating him as a guest of honor, sincerely inviting Liu Bei to preside over the government of Xuzhou to show his heartfelt loyalty to the Han Dynasty. Liu Bei expressed his gratitude, but he could never accept this request and stayed in Xiaopei for a while. Liu Bei reluctantly agreed to the request. Subsequently, Tao Qian died of illness and his son was young, and Liu Bei took charge of Xuzhou.

After Li Jue and Guo Si took control of Emperor Xian due to disagreement, Yang Feng and Dong Cheng escaped from Chang'an and arrived at Luoyang. Yang Biao, the lieutenant, advised Cao Cao that he had a strong army and could be summoned to the court to assist the royal family, so he sent an envoy to summon Cao Cao to the court. When Cao Cao heard that Emperor Xian had arrived in Luoyang, he was preparing to go to protect the Emperor to gain the public's expectation, when the messenger of the Son of Heaven arrived, Cao Cao was very happy and led his army to the court. When Cao Cao followed the Emperor, Li Jue Guo Si came after him and killed him.

Yuan Shu leads an army to attack Xuzhou. Yuan Shu writes to Lu Bu promising to send 200,000 drachms of rice to induce him to attack Xiapi, and Yuan Shu thus defeats Liu Bei and captures Xuzhou, including Guangling. In order to seize Xuzhou, Yuan Shu incited Hao Meng, a general of Lu Bu's army, to mutiny, but in time, Gao Shun, a general of Lu Bu, put down Hao Meng's rebellion. For this reason, Yuan Shu, fearing that Lu Bu would endanger himself, asked Lu Bu's daughter for his son's hand in marriage, which Lu Bu agreed to, and after relieving his worries, Yuan Shu once again pointed his sword at Liu Bei.

Cao Cao conquers Wancheng, Zhang Xiu is defeated and surrenders; Cao Cao mistakenly listens to his nephew An Min's encouragement and takes Zhang's aunt Zou's mother captive. Zhang Xiu is furious, but fearing the courage of Deng Wei, he uses Jia's plan and sends Hu Che to steal Deng's two halberds and attack Cao's camp at night. Zhang Xiu stabbed Zou's mother to death.

Lu Bu, trapped in Xiapi City, resisted Cao's attack on the White Gate Tower from morning until noon, exhausted, when the enemy army retreated a little, Bu rested on a chair in front of the enemy building and passed out without realizing it. The two generals under him, Song Xian and Wei Xu, took advantage of his drowsiness to drive away his guards and captured Lu Bu alive.

Cao Cao is a powerful man who is holding the emperor's son hostage, but Liu Bei is a weak man who has to plant vegetables in the back garden of his house to prevent Cao Cao from plotting against him. Guan Yunzhang and Zhang Fei are in the dark, saying that Liu Bei does not pay attention to the world's major events, but learns from the villain.

The situation was that Cao Cao attacked Xuzhou, Liu Bei's army was defeated, and Liu Bei didn't care about his wife and fled. Cao Cao's general Zhang Liao, who was a good friend of Guan Yu, went to persuade him to surrender, and Guan Yu agreed to do these three things with Cao Cao. Cao Cao promised that Guan Yu would surrender; otherwise, he would rather die than surrender.

Guan Yu and Liu Bei are separated in Xiapi, and Guan Yu is trapped in Cao's camp. Liu Bei goes to Yuan Shao, Guan Yu learns of Liu Bei's whereabouts, and single-handedly protects his sister-in-law for a thousand miles to find his brother. In the five levels, he was stopped by Kong Xiu, Han Fu, Meng Tan, Bian Xi, Wang Zhi and Qin Qi; Guan Yu was forced to go through five levels and cut down six generals. Finally, in the ancient city, the brothers, the ruler and the couple met.

Liu Bei was defeated by Cao Cao in Xuzhou, and was separated from Guan Yu, Zhang Fei and Zhao Yun, so he joined Yuan Shao. At the same time, Guan Yu and Cao Cao about three things, what to protect Liu Bei's family, what to surrender Han not Cao, mainly the last one, know Liu Bei to go, immediately after the flash. You do not say, Cao Cao really agreed.

Yuan Shao, with hundreds of thousands of troops, occupied the states and counties north of the Yellow River, such as You, Ji, Qing, and He, and was in a favorable position to attack and retreat to defend. Cao Cao occupied the states and counties south of the Yellow River, such as Gun, Yu and Xu, and received Emperor Xian of Han in Xuchang to "hold the Son of Heaven and make the vassals". However, Cao Cao only had tens of thousands of troops and was located in a geographic location that was easy to attack and difficult to defend, and his rear was not consolidated, as Liu Biao in Jingzhou, Sun Ce in Jiangdong and Zhang Xiu in Nanyang were still enemies of Cao Cao. Therefore, the overall combat situation was favorable to Yuan but not to Cao.

When the reinforced Yuan cavalry approached Wu Chao, the left and right reported to Cao Cao to divide their troops to resist, Cao Cao was furious and said, "Tell me again only when the enemy soldiers have reached my back!" So the soldiers all fought to the death and defeated the defenders of Wu Chao and captured Yuan general Chun Yu Qiong. The two generals, Zhang He Semi and Gao Lan, who were attacking Cao's camp, heard that Chun Yu Qiong had been defeated and that Yuan Shao was suspicious of them, so they surrendered to Cao Cao at the front of the battle. Yuan Shao and his son Yuan Tan fled to the north of the river with only 800 horses.

Liu Bei heard that Zhuge Liang is very talented, with gifts to Longzhong Wolong Gang to ask him to assist. This day it happens that Zhuge Liang is not in, can only be disappointed and return. Soon after, Liu Bei, Guan Yu and Zhang Fei went to ask Zhuge Liang for the second time in a heavy snowstorm. But Zhuge Liang was out for a leisurely trip again. After some time, Liu Bei ate vegetarian for three days and was ready to ask Zhuge Liang again. Guan Yu said that Zhuge Liang might have a false name and might not have the real talent, so he did not need to go. But Zhang Fei advocated that he should go alone to call, and if he did not come, he should be tied with a rope. Liu Bei reprimanded Zhang Fei and visited Zhuge Liang for the third time with both of them.

Liu Bei did not dare to disturb him and stood until Zhuge Liang himself woke up before sitting down to talk with each other. When Zhuge Liang saw that Liu Bei had the will to work for his country and sincerely asked for his help, he came out to fully help Liu Bei establish the Shu Han Dynasty.

In the battle of Chang Ban Po, Zhao Yun is responsible for protecting Gan, Mi and A Dou, but due to the chaos of war, Zhao Yun gets separated from them, so he leads 30-40 followers to go back and look for them, but after looking around, he fails to find them but kills Chun Yu and saves Mi Zhu and Gan. Zhao Yun sent them to Chang Ban Bridge and was almost misunderstood by Zhang Fei as betraying Liu Bei, thanks to the explanation of Jane Yong to clarify the fact. Zhao Yun then entrusted Mrs. Gan to Zhang Fei and turned back to look for Ah Dou, but at that time he was alone, without an attendant.

Liu Bei is defeated by Cao Cao and escapes with the people. In this battle, Liu Bei loses his heavily supplied army, his two daughters are captured by Cao Chun, Liu Bei gains time to escape due to Zhang Fei breaking the bridge by water, while Lady Gan and Liu Chan are spared under the protection of Zhao Yun. After the battle, Liu Bei gave up his plan to transfer to Jiangling and went to Jiangxia to join Liu Qi, the eldest son of Liu Biao.

Cao Cao is the only one who knows that it will be difficult to annex these two forces at once. So, Cao Cao sent someone with his letter to East Wu, wanting to join hands with Sun Quan to destroy Liu Bei.

Upon receiving Cao Cao's challenge letter, Zhou Yu, the governor of Eastern Wu, destroys the book and beheads the envoy to show his determination to resist. This triggers some fighting between Cao Cao and Eastern Wu at the mouth of the Three Rivers. Zhou Yu has won the battle, but he still manages to be cautious, conducts research and spies on Cao's camp overnight.

Zhou Yu deliberately proposes to make 100,000 arrows in ten days. The wise Zhuge Liang recognizes at once that it is a harmful scheme, but calmly says "it only takes three days". Later, with the help of a foggy day, Zhuge Liang takes advantage of Cao Cao's suspicious nature and transfers several straw boats to lure the enemy, finally borrowing 100,000 arrows and achieving a miraculous success.

Sun and Liu joined forces to resist Cao, in order to succeed, Huang Gai accepted Zhou Yu's bitter plan, deliberately said in front of Zhou Yu to surrender Cao, Zhou Yu then beat Huang Gai a hundred big boards, did not expect to beat 50 boards, Huang Gai because of his old age, immediately fainted, at that time and some people such as Lu Su pleaded for mercy, so they helped him down.

In the Battle of Red Cliff, Sun Quan and Liu Bei are fighting against Cao Cao's 800,000-strong army, and there is a huge difference between the two armies. Zhou Yu and Zhuge Liang decide to use a fire plan against Cao Cao. After Huang Gai's bitter meat plan and Pang Tong's chain of plans, they prepared to implement a fire attack to defeat Cao Cao's army, but it was the middle of winter and there was no southeast wind, so the fire plan could not be implemented. Zhuge Liang said that he could borrow the east wind to help the fire plan succeed. So on the night of the general attack, Zhuge Liang succeeded in borrowing the east wind at the altar and the fire attack was effective, defeating Cao's army.

Sun Quan orders Zhou Yu to be the main general and Cheng Pu to be his deputy, leading 30,000 elite naval troops, together with Liu Bei's army stationed at Fan Kou, a total of about 50,000 men to move westward along the Yangtze River to meet Cao's army. Sun and Liu allied forces confronted Cao's army at Chibi. Cao Cao linked his warships together as one, so that he could practice his navy and wait for an opportunity to attack. Zhou Yu adopts the fire attack plan proposed by his general Huang Gai and has him send a letter to Cao Cao to fraudulently surrender.

After Zhou Yu defeats Cao Cao at the Battle of Red Cliff, he reorganizes his troops and prepares to take the Southern County. Sun Qian comes to congratulate him on Liu Bei's order. Zhou Yu learns that Liu Bei is preparing to take the South County, so he negotiates with Liu Bei under the pretext of thanking him.

In the name of letting Liu Bei and Sun Shangxiang get married, Zhou Yu tricked Liu Bei into coming to Eastern Wu and taking him hostage so that he could take back Jingzhou. As a result, he fell for Zhuge Liang's brilliant plan and not only did he not get Jingzhou back, but he made Liu Bei marry Sun and return to Jingzhou safely.

After Liu Bei crossed the river, Mrs. Wu hosted a banquet to meet Liu Bei at the Ganlu Temple, but Sun Quan and Jia Hua interfered with him.

When Zhou Yu attacked Nan County, he was struck by a poisoned arrow. When Zhuge Liang takes advantage of the chaos and uses a plan to take Nan County, Jingzhou and Xiangyang first, Zhou Yu suffers a recurrence of his arrow wound. When he fell ill, Zhou Yu tried to take Jingzhou, but Zhuge Liang was able to see through it. He died in a fit of resentment, saying, "If you are born with Yu, why should you be born with Liang? When Zhuge Liang learns of Zhou Yu's death, he decides to go and offer his condolences.
