The Nantes Volunteer Army had not yet recovered from the shock, and the two armies of the Sero government army had already arrived at their destination. The Nantes Volunteers had already suffered heavy casualties in the explosion in the city, more than 70,000 people were unknown in their lives, and the rest of the troops were desperately trying to rescue the wounded, and there were not many alert troops at all, and when the Sero government army launched a surprise attack on them, the Nantes Volunteers were completely unable to organize an effective defense, and after several hours of fierce fighting, they were forced to retreat with heavy losses.

Although the Sero government army barely held the city of Toledo in the rear, the supply of the whole city was destroyed, and the Madrid defenders who lacked supplies had no choice but to rely on the support of the Sardinia mercenaries to fight, but the materials of the Sardinia mercenaries were not too rich, and the ammunition and food of the Sero defenders began to be increasingly scarce, and the lack of ammunition supply caused their combat effectiveness to decline sharply.

Seeing this, Franco was ruthless, and he ordered the rebels to launch a massive attack at any cost in order to consume the opponent's small ammunition. Under the high-intensity attack of the rebels, the Sero government army reluctantly retreated step by step and was soon squeezed out of the city of Madrid. The defeated government forces lost the city's barriers, and were even more unable to confront the rebels, and they had to move eastward under the leadership of Carlos I.

Carlos I retreated east to fight the Sardinian mercenaries, and the two sides joined forces to defend the southern part of the Sero Kingdom, and he attempted to rely on the naval support of the Grand Duchy of Sardinia to hold the eastern part of the Sero Kingdom, waiting for the allies to send new reinforcements. However, when he received the news of the fall of Madrid, the Sardinia mercenaries immediately withdrew from their positions.

Seeing that the general trend was gone, the Sardinia mercenaries did not hesitate to evacuate in a hurry, without even giving any news to the friendly forces. The Sardinian army marched directly towards the port of Cartagena, trying to use the port facilities there to retreat back to the country, but they decided to leave it alone.

Carlos I was dismayed by the retreat of the Sardinian mercenaries who chose to retreat without informing their allies, and on the way his troops were confronted by the rebels who were following south due to the retreat of the Sardinian mercenaries, and the troops belonging to the rebel 40th Army launched a fierce attack on the advancing Sero government forces. The already demoralized government troops thought they were frightened, and after the surprise attack, they did not carefully reconnoiter how many attacking troops there were, and the army broke up directly.

With less than 10,000 remaining soldiers, Carlos I fled day and night, and finally arrived at the port of Cartagena before the Sardinian mercenaries could leave. The Sardinia mercenaries did not want to ignore their allies, and they brought them with their spare transport ships.

The departure of Carlos I marked the end of the Bourbon dynasty of the Cerro kingdom and the complete defeat of the allies in this game. Soon Franco changed the state system of the Kingdom of Sero, established the Republic of Sero, and formed the National Assembly. In fact, Franco was the president himself, and the parliament was composed entirely of his cronies, and he completely monopolized the power in the country, turning the so-called republic into his dictatorship.

After coming to power, Franco pursued a policy of repression at home, brutally persecuting and cracking down on those who remained loyal to the Bourbons. He vigorously promoted fascism at home, purged dissidents, and consolidated his regime. In order to gain the support of the Boston Empire, Franco soon announced that the Republic of Cerro had joined the Axis bloc, along with the Grand Duchy of Rees, where the regime was also overthrown, the entire family of the Grand Duke of Rees was killed, and the newly formed government officials were replaced by Franco's cronies.

Just after the formation of the new governments, the Allied bloc announced that it did not recognize the legitimacy of the two governments, claiming to retaliate against them. Fang Ruijun then announced that the Chinese Empire did not recognize the newly established rebel governments of the two countries, and called on the Axis powers not to admit the two countries and to severely punish those who slaughtered government officials.

Even if the Allies and NATO are all opposed, the Boston Empire will not spit out the fat in its mouth, and there is no international organization in the world that unites most countries to regulate international affairs within the world realm, so other countries are helpless to ignore the Boston Empire.

Doing nothing is not Fang Ruijun's style, he directly summoned the ambassador of the Yaman Empire, announced that he was willing to sell a batch of Golden Eagle 4 fighters to him at a low price, in addition to transferring the technology of some tanks and aircraft at a low price, Ambassador Yaman was happy from the sky this time, and he also vaguely knew why Fang Ruijun wanted to help so much, and he was secretly happy about this.

In addition, Fang Ruijun agreed to Carlos I's application for political asylum, and at the same time recruited many people loyal to the dynasty for him, organized these exiles abroad, and helped Carlos I form the government-in-exile of the Kingdom of Sero in the Chinese Empire, and confronted Franco. This series of actions of the Chinese Empire frightened the Boston Empire, and they thought that Fang Ruijun was going to unite with the Allies to jointly deal with the Axis bloc.

Although the Axis powers had grown rapidly during the period of their existence, the Boston Empire knew very well that although they surpassed the Allies in strength, they still could not compete with NATO. Now the Axis bloc is trying its best to compress the living space of the Allies, which has made the other side have a sense of crisis, and if NATO takes the opportunity of this coup d'état to completely unite with the Allies to deal with itself, I believe that the Axis will not be able to support it for long, so the Boston Empire hurriedly sent a special envoy to Beijing to explain, hoping to calm the anger of the Chinese Empire.

The Yaman Empire, the core of the Allies, did not fail to see the benefits of relying on NATO against the Axis powers, but Wilhelm II also knew very well that if he chose to defect to NATO, the Axis bloc would soon be destroyed. However, after the demise of the Axis bloc, the Allied bloc lost its usefulness, and in the face of a powerful NATO, the Allied bloc will soon be eliminated, so he decided to keep a certain distance from the NATO alliance, so as not to misunderstand the Axis powers, and at the same time hoped that both sides would not be provoked, so that both of them would be pinched to the death, and the Allied bloc would be able to find space to survive in the cracks.

Just a few days after the Chinese Empire issued a statement in support of Carlos I's formation of a government-in-exile, the Boston envoy met with Fang Ruijun, and after friendly talks, the Boston Empire hoped to calm the turmoil at the expense of opening up part of its domestic market.

In fact, Fang Ruijun would never forget the loss of the Chinese Empire in the Western Continent because of such a small profit, but in his plan, it was necessary to strengthen the strength of the Axis powers in the Western Continent, so that they could form enough pressure on the Allies to force the two sides to go to war, so as to break the current three-legged balance of power in the world.

Therefore, after communicating with the Congress, the Congress authorized the Cabinet to be fully responsible for external affairs, and Fang Ruijun could provide suggestions for it, and these decisions did not need to be approved by the Congress, which was also a new decision made by the two houses of the Congress after seeing the ability of Fang Ruijun and the cabinet to control.

Because many of these things need to be kept secret in advance, if everything needs to be approved by the Congress, it will inevitably leak out under the mixed mouth, which will cause unnecessary losses to the country, which is also an exploration made by the political elites of the Chinese Empire to improve this system after Fang Xiaoyu built the structure of the constitutional monarchy.

In any case, the fall of Russia marked the end of the Cossack Civil War, and the change of hands between Sero and Reese gave the Axis powers a significant advantage on the Western Continent. The mutual containment of the alliance of the three major countries has suddenly calmed down the pattern of the world, but under the calm, the entire world is already an undercurrent, and all countries know very well that a new world war will come soon, and they can only step up their own armament construction in addition to being vigilant against the actions of neighboring countries.

The undercurrent surging in the world realm made Fang Ruijun also vigilant, but Fang Xiaoyu, who had abdicated to make way for Xian, didn't care about it, at this time he was leading a group of concubines to carry out city construction on the return star, and he was accompanied by more than 10 million residents of China Island.

With Fang Xiaoyu's ultra-long-distance teleportation function, all kinds of building materials and materials can be continuously transported to the return star through Xiaofeng's ability, and Fang Xiaoyu led tens of millions of islanders to start a new planet development.

The place where the advance party landed was located on a large grassland with an area of more than a million square kilometers, crossed by five large rivers with abundant water, and the terrain was quite suitable for the initial development of the immigrants.

Fang Xiaoyu named the entire region of the Regression Star after the name of the earth, so this steppe was named the Mongolian steppe by Fang Xiaoyu. Near the landing site was a large river, which Fang Xiaoyu named the Tule River, and the islanders built a new city.

The new city was named Tianjin City, which is the name of Fang Xiaoyu's hometown, and will be used as a base for the development of the return star to support all development activities in the future. Tianjin City is very large, the urban area alone covers an area of 5,000 square kilometers, and the whole city is completely in accordance with the modern urban design, which also draws on many construction experiences of China City and Beijing City.

In order to power the city, the team built a solar power plant outside the city, although the solar power generation is inefficient and can barely supply tens of millions of people for a limited time, but this is only a temporary measure, in the upper reaches of the Thule River, dozens of kilometers away from the city of Tianjin, a dam is being built, where a large hydropower station will be built to power the city and the city that may be built in the nearby area.

Fang Xiaoyu was very careful about the development of the new planet, he wanted to build the Return Star into his first base towards the universe. Nowadays, the technology is very advanced, and there is no need to repeat those high-energy-consuming and high-polluting industrial construction, so the construction of the China Foundation here will follow the principles of clean environmental protection and minimizing ecological damage.
