In the evening, outside the city of San Luis Potosí in central Mexico. Liberal President Juárez panted for breath.

Three days earlier, he had been in Mexico City planning to send troops against the invasion of western Mexico with an army of 20,000. The American envoy had promised him that he would be willing to help their liberals, of course, at the cost of ceding the Lower California peninsula to the United States, and he did not agree to this in person. Moreover, according to information from the east, the Spanish troops that landed had conquered several small towns, but they had been entangled by the liberal troops in the eastern state of Tamaulipas; The French army attacking Puebla City has also been blocked by the Puebla defenders led by General Zaragoza, although the situation is not good, but there is no trend of further deterioration, with his entry into Mexico City, in order to defend the capital, he deployed tens of thousands of troops in Mexico City, and let his close general Porfirio Díaz be in charge of the defense of Mexico City. As for the troops of the eastern countries that had already been inquired about from the west, he no longer had the panic he had when he first heard the news.

At the beginning, I thought it was the armies of European countries, and it was really Mexico's end. But when he learned that it was the original Qing country in the East that sold tea and silk, he was much more relieved. Although he doesn't understand how these Qing people got here, but the Qing army suffered a crushing defeat in the war with the British army more than ten years ago, he knew that this was a backward army, although the weapons of his Mexican army were not very good, but after the Mexican War of Independence and the American War, coupled with the civil war in the past few years, today's Mexican army is definitely not comparable to those backward eastern armies. Not to mention defending the city in their own way! Even if the army is only more than 10,000, there is no fear, there are so many civilians in Mexico City, a little organization can allow them to go to the city to defend. The only pity is that the liberals have just occupied Mexico City, but it doesn't matter, they have already sent the liberal army in the center to gather reinforcements, and when the 20,000 Qing troops arrive in Mexico City, the reinforcements should have arrived early. The fatal threat was also the French forces besieging the city of Puebla in the southeast.

Unexpectedly, that night, the Qing army seemed to fall from the sky and attacked Chapultepec Castle in the west of Mexico City, occupying Chapultepec Hill and Chapultepec Castle, which overlooked Mexico City.

Early the next morning, the Qing army was unusually ferocious and directly erected artillery to bombard the western city wall from a long distance, and in less than a morning, 12 of the 20 cannons arranged on the western city wall were dumb fired, and although the remaining 8 cannons were not destroyed, the gunners who opened the artillery were also frightened and hid in a panic, and it was difficult to organize an effective counterattack. Under the fierce attack of the dense and fearless Qing army, Mexico City, which had been somewhat damaged and had not been repaired, was captured.

Juarez ordered his confidant Díaz to organize nearly 10,000 Mexican troops in the city to resist to the death and conduct street battles, but unexpectedly, those Qing troops took out some terrifying demonic weapons, such as Congreve rocket artillery, but they were much more powerful than rocket artillery, almost setting fire to half of the western block of Mexico City, and countless soldiers and civilians resisting in the west of Mexico City were killed and wounded.

Juárez saw that the situation was not good, and at this time, the American minister in Mexico City also came to him and persuaded him to move the capital and lead the army to retreat to northern Mexico, so that it would be easier to obtain the support of the American government, so he led the liberal government and 2,000 cronies to retreat north. Not long after leaving the north gate of Mexico City, he was shocked by the news that his cronies, Mexico City defender Dias, had given up resistance and surrendered to the enemy. Mexico City is occupied!

Horrified in his heart, he hurriedly fled north, until he reached the outside of San Luis Potosi, which was hundreds of kilometers away, and then stopped to breathe a sigh of relief. At this moment, he didn't have time to hate Diaz, a close confidant who betrayed him, and just wanted to run to the safer northern states and counties of Mexico as soon as possible, and then organize patriotic Mexican soldiers and civilians to resist foreign enemies.

After two days of travel, Juárez finally led his troops to Monterrey, the capital of Nuevo León in northeastern Mexico, which is not far from the U.S. border and the second largest city in Mexico, Juárez announced the establishment of a new Mexican government, and positioned Monterrey as the capital of Mexico.

At the same time, Ferdinand Maximilian Joseph von Habsburg-Lorraine, the envoy of the French Emperor and Archduke of Austria, together with General Lorenz, commander of the French Expeditionary Force, and Archbishop Garza, the head of the Mexican Catholic Church, announced that the French army had entered Mexico to help Mexico develop its industry and recover its debts, to help the Mexican people return to the embrace of Catholicism, and to prepare to unify the whole of Mexico within three months. As soon as the news spread, although it had not yet reached Europe and other places, the United States, Central America and other countries, as well as European ambassadors to the United States, were already shaken.

And at this time, in Mexico City, it is a different situation!

General Lorenz, the commander of the French Expeditionary Force, looked at the western neighborhood of Mexico City that was charred into ruins with a pale face, and his heart was already churning up and down, shocked!

Before that, he already knew that the Allied forces from the east had conquered Mexico City. Although he was surprised, he thought that there were more than 20,000 people in the expeditionary force of the Chinese Empire, and he received the news that the defender of Mexico City, Dias, had surrendered, so he did not pay much attention to it. But when he arrived outside Mexico City from Puebla City, Archbishop Garza and other Mexican conservatives who came to greet him told him that Díaz and the liberal army had surrendered after the other side had broken through Mexico City and had been defeated and cornered.

When he saw the appearance of the west of the city that was conquered by the Chinese Imperial Expeditionary Force, he realized that even if he led 7,000 French troops to defend Mexico City, it would be the result of being captured, and even his 7,000 French troops were only afraid of heavy losses. He could tell from the scorched black earth that this was not a simple burning of the city, but like the capture of the fortress outside Puebla, the Orientals had used their diabolical weapons to completely burn down the entire western neighborhood of Mexico City.

Thinking of this, he couldn't help but tighten his neck, feeling a chill in his back! Originally, he wanted to use these Orientals to help siege the city, and after the final defeat of the Mexican liberal government army, he would reduce his interests depending on the situation, and not let the other side control all the seven states in northern Mexico, but now it seems that he can only abide by the agreement.

A month later, with the advance of the French, Spanish, and Mexican conservative armies, the Mexican liberal forces were defeated, and the conservatives were so powerful in the southern and northern countryside of Mexico that the liberal forces were defeated, and eventually, the liberal government with Juárez as president could only control the states of Nuevo León, Coahuila, and northern Tamaulipas around Monterrey, and even the capital of Tamaulipas, Ciudad Victoria, was captured by the French. With the exception of these three states, all of Mexico has been occupied and controlled by the coalition led by the French army.

At this time, a news came out that shocked the Western world: the representatives of the coalition announced in Mexico City the establishment of the Mexican Empire, with the French envoy and Austrian Archduke Maximilian as the first emperor of the new Mexican Empire. At the same time, representatives of France, Spain, the Chinese Empire, and the newly formed Mexican Empire signed the Four-Power Treaty of Mexico City in Mexico City. For a moment, the whole world was shocked!
