In June 1259 AD, outside Diaoyu City, there was a lot of war.

The vanguard of the Mongolian army is struggling to climb towards the wall of the Diaoyu City, which stands on a steep mountain wall, under the scorching sun above the head, and the boulders, logs, and arrows rolling down from the city have become all The nightmare of the besieger, whenever a shadow falls from the top of the wall, the wall

The sounds of broken bones and screams sounded over and over again amidst the blood splattered and the shouts of the siege.

Xia Pingan turned into Wang Jian, wearing armor, standing majestically on the tower outside the Diaoyu City, looking into the distance, looking at the barracks of the Mongolian army outside the city and the "Wang" character that appeared and disappeared in the barracks of the Mongolian army on the other side. Daqi's face was calm and unwavering, as if he was looking at a frozen landscape painting.

The lieutenant general Zhang Jue who followed Xia Ping'an and the generals and sergeants guarding the city did not panic when they saw the commander was so calm, and fought bravely.

Ever since Wang Jian beheaded the Jin national treasure sent by the Mongolian army to persuade him to surrender, everyone knew that Diaoyu City and the Mongolian army were immortal. The commander is not afraid of death, and even put his son in the city to fight against the enemy with everyone. Why are the rest of the people in Diaoyu City afraid of being killed?

Xia Ping'an was on the city wall, but his thoughts had already passed through the field of vision of his eyes and flew far away. Because for the soldiers and civilians who are sticking to Diaoyu City at this moment, they may not realize how much impact this upcoming war test will have on the entire world. None of the defenders and soldiers in the city thought what kind of miracles and brilliance they would create in the world's military history with their persistence and bravery at this moment!

At this moment, the entire Eurasian continent, wherever Mongolia's iron hooves go, the sharpness of God's whip is shaking the entire eastern and western worlds.

The army led by Kublai Khan had destroyed the Dali Kingdom in Yunnan, and the Southern Song Dynasty was besieged on all sides.

At this time, Hulagu had already occupied Persia, Syria, Palestine and other West Asian countries, and pointed his sword at the Mamluk dynasty in Egypt.

Like an eight-clawed monster entrenched in the Eurasian continent, the mighty Central Mongolian Empire attacked everywhere, displaying barbaric pride. The entire Confucian civilization, Christian civilization and Christian civilization were trembling and in danger.

At the end of last year, the powerful Central Mongolian Empire tried its best to assemble three armies to destroy the Southern Song Dynasty. The first route was led by Kublai Khan, the younger brother of the Great Khan Mengge, and attacked from north to south to EZ; the second group of troops set out from Yunnan. , passed through Guangxi and entered the Southern Song Dynasty to reconcile with Kublai Khan; the third route was led by Meng Ge Khan himself, and Meng Ge Da Khan set out from Ningxia, preparing to enter the Southern Song Dynasty via Sichuan, and finally the army of the three routes gathered in one place and went straight to the capital Lin'an .

The progress of the other two armies was relatively smooth. At this moment, Kublai Khan was about to approach Lin'an City.

The 100,000 Mongolian West Road Army led by Mengge Dahan, all the way like a broken bamboo, attacked the city and seized the land. After breaking through the Jianmen, they swept across Langzhou, Pengzhou, Qingju City, Longzhou, Yazhou, and all the western and central Sichuan regions. When the Mongolian army came to Diaoyu City, it was like a surging wave hitting a black steel reef, and had to stop

It has been five years since Xia Pingan became Wang Jian in this world. When he first entered Jiezhu, it was in 1254 AD. Because of his meritorious service in the war against Mongolia, Wang Jian was promoted by the Southern Song Dynasty to be the governor of Xingyuan Prefecture and to know Hezhou. Fishing city defense.

When Xia Pingan took office, he mobilized more than hundreds of thousands of soldiers and civilians from the five counties under his jurisdiction in accordance with Wang Jian's strategies and methods in history, and began to build a three-dimensional defense system in Diaoyu City.

The Diaoyu City was not built from the beginning of Wang Jian. As early as the third year of Chunyou (1243), Yu Jie, the minister of the Ministry of War, the governor of Sichuan and the prefect of Chongqing, adopted the suggestion of the brothers Ran Jin and Ran Pu, and followed the "combination of the city and the fortress, The strategic defense thought of "combining military administration and administration" built the Diaoyu Mountain city, moved the administrative offices of Hezhou and Shizhao County into the city, stationed troops to accumulate food, recruited talented people, and thus laid the foundation of Diaoyu City and opened it up. The prelude to the 36-year defense of Diaoyu City.
