Ignoring the gap in the enemy's firepower, the Japanese soldiers quickly rushed across the beach and launched an attack on the fortifications on the hill, regardless of their own heavy casualties, and then the second group of San Martin soldiers on board also began to board the ship to attack, strongly supporting the actions of the Japanese troops.

Although the Japanese soldiers were attacking from the back and the terrain was very unfavorable, they were numerous, and with the help of the superior firepower of the Chinese Empire, the progress was quite smooth. After a targeted purge by the Second Artillery Corps and naval guns, the Japanese soldiers and the subsequent soldiers of the St. Martin Empire captured the Marokee fortress in five hours at the cost of more than 26,000 casualties. Subsequently, a large number of follow-up troops of the St. Martin Empire and the Chinese Empire landed one after another and began to attack and advance into the inland areas.

After receiving the news that the Imperial Chinese Army had landed in the south, the governments of the Entente countries were shocked, and the Kingdom of Sero immediately joined forces with the Grand Duchy of Rees to carry out another national mobilization, and reluctantly formed an army of 800,000 people with the intention of defending to the death and consuming the strength of the Chinese Empire, but the Imperial Chinese Army did not give them this opportunity at all.

Under the cover of the Grizzly 1 tank, the Wehrmacht units did not fight with the other side at all, but directly cut through the opponent's defense line like a quick knife, dividing and encircling the opposing troops and cutting off their logistical supplies.

In just ten days, the combined forces of the Kingdom of Sero and the Grand Duchy of Rees collapsed, and only less than 200,000 troops withdrew to Madrid, the capital of the Kingdom of Sero, intending to fight a city street battle with the Chinese Empire, striving to give the other side enough casualties to make the Chinese Imperial army retreat.

For the abacus of the Sero Kingdom, Su Zhizhen would not follow, and he didn't want to fight in the streets at all. For a prosperous metropolis in the western continent like Madrid, if it was attacked by countries in the western continent, he would have some scruples, but he didn't come to fight.

Therefore, the Imperial Chinese Army directly mounted various types of artillery on the edge of the city. In the early hours of 1 December, the F-FDTL rocket artillery units launched the first attack, and a dense stream of rockets with long tail flames streaked across the sky, waking up the sleeping residents of Madrid.

One after another explosions rang out, turning the center of Madrid into a sea of fire, and then the various types of artillery belonging to the Imperial Chinese Army and the Imperial Army of San Martin began to roar together, and even the Second Artillery Corps came to join in the fun. Dense shells rained down on the city, leveling everything above the ground, and hundreds of thousands of Cerro defenders were caught off guard and suffered heavy losses.

Su Zhizhen did not have the slightest concern for civilians or monuments, nor did he have any idea of saving ammunition, he just wanted to play the momentum and majesty of the Imperial Chinese Army here, and tell everyone who dared to resist that as long as they wanted to resist, they must be prepared to pay a sufficient price.

The shelling lasted for three hours, and if it weren't for the fact that Madrid was not too far from the sea, and the Chinese Empire could get a steady supply of ammunition from the sea, I am afraid that this shelling would have exhausted the entire army's ammunition stock.

After the shelling, the Japanese army sent three corps of troops into the city to search, at this time the city of Madrid has become a ruin, the number of surviving defenders is much smaller, the Japanese soldiers are not afraid of death at all, they rampant in the city, and the Madrid defenders have fought a war of attrition.

Su Zhizhen didn't care about the consumption of the Japanese soldiers, and then he sent the remaining Japanese soldiers into the city, and in this cruel urban strangulation battle, the Japanese soldiers killed more than 100,000 soldiers. In the end, the 30,000 Sero defenders, who were defeated by the fierce Japanese soldiers, raised their hands and surrendered.

The weather in December was already very cold, even in the territory of the Kingdom of Sailuo, which was relatively close to the south, and even if the Imperial Army had made adequate preparations for the winter battle, Su Zhizhen did not have any intention of delaying the progress of the war.

Now it's all about speed, to eliminate the Kingdom of Sero and the Grand Duchy of Rees before the Entente reacts, as long as the army advances to the Pyrenees on the border with southern Cyprus, it can build a strong defensive line to block the Entente army that may come back, where it is easier to build fortifications and completely block the entire peninsula region with fewer troops.

With the army's artillery long-range fire, shells and rockets fell as if they didn't need money, directly destroying the entrenchment of any Sero resistance, and a large number of Sero cities were directly destroyed, and under the frenzied attack of the fierce Japanese soldiers that followed, the Sero people quickly became timid, they had never seen such a decisive way of attacking.

Su Zhizhen's intentions are obvious, the Imperial Army will carry out fire support, how fierce and fierce the firepower will be, and he will not care about the shells at all, once there is a chance to engage the enemy in close combat and let the servant army go up, the lives of the soldiers of the Imperial Army will be much more precious than the servant army.

Under such a fierce artillery fire and the desperate assault of the servant army, especially the Japanese soldiers, with the rapid advance of the chariot troops, the Imperial Army reached the Pyrenees Mountains within ten days, and soon began to build defenses, and at the same time, the eight armies of the Imperial Army and the remaining Japanese soldiers went east, and the fourteen armies of the three armies including St. Martin went west, quickly occupying the entire territory of the Kingdom of Sero and the Grand Duchy of Rees.

The landing operation of the Imperial Chinese Army was so sudden that the Entente was somewhat caught by surprise. Originally, they thought that the Yaman Empire and other traditional powers in the Western Continent would not allow the Chinese Empire to interfere in the affairs of the Western Continent alone, at least not let them send their land forces to independently attack the Western Continent from one direction, but they did not expect that the governments of the Allied countries, which had been overwhelmed by the war expenses, would be so resolute that in order to end the war as soon as possible, they actually agreed to open up a new battlefield for the other side.

The advance speed of the Imperial Chinese Army was too fast, and most of the Allied troops gathered on the border battlefield between Nantes and Yaman had no time to react, and the Chinese Empire had already advanced to the border of Nantes Sero, so they had no choice but to put together their troops and gather at the northern foot of the Pyrenees, carefully guarding against the surprise attack of the Imperial Chinese Army.

The reason why the Chinese Empire sent its army into the Western Continent to fight was mainly due to political considerations, and now that it has obtained enough results, it is natural that it will no longer consume its own combat power in vain, and the two sides will coexist peacefully in the Pyrenees.

The only thing that upset the Entente was that with the surrender of the Kingdom of Cerro and the Grand Duchy of Rees, nearly half a million troops from both countries fighting on the front line demanded to return home. The Saar Empire and the Nantes Empire were not so easy to talk to, they directly pulled down their faces, seized the command of the armies of the two countries, and drove them to continue fighting.
