Zhu Di cut off Song Zhong and Yu Yao to occupy the important land of Youyan, and surrounded Longmen, Shanggu, Yunzhong, and Kaiping City, and sure enough, everyone was afraid and looked forward to the wind. For a time, the land of clouds was only ten months, and most of them had already been stationed in the Yan army.

Zhu Lu, the king of the valley, guarded the Xuanfu adjacent to Beiping, and heard that Zhu Di raised troops to raise troops and rejuvenate the army, and was timid in his heart. He knew that his fourth brother was so powerful that he didn't dare to be an enemy, so he abandoned the fiefdom of the Baili Land and the domain, and only led thousands of guards named the Qin Dynasty to flee to Beijing.

In this way, the northern Xinjiang changed and the Ming court was shaken, and Zhu Yunwen originally thought that the governor Song Zhong had collected all the soldiers and horses in Yandi, and Zhu Di was lonely and decided to arrest him. I never thought that after a few battles, the official army was defeated and the main general would die, which made Zhu Yunwen shocked and angry, and on the one hand he told the Taimiao to depose Zhu Di as a concubine, and on the other hand, he convened the civil and military courtiers to discuss countermeasures.

At that time, most of the founding fathers of the Ming Dynasty had been cooked by Zhu Yuanzhang's rabbit and dog. The courtiers discussed for a long time and felt that they would fight against the Yan army, and they had to be in command of Geng Bingwen, the Marquis of Changxing. Zhu Yunwen immediately issued an order to appoint Geng Bingwen as the general of the conquest, and transferred 300,000 elite soldiers from Gyeonggi and various state capitals to the Northern Expedition to Yandi.

Geng Bingwen found out that Zhu Di claimed to be in Fengtianjing, and he was under the command of the old commander of the Yan Division, and recruited the Zhou and Wu rebels to fight against the imperial court for his own use.

Therefore, the army was divided into four routes, with General Zuo Yangsong as the vanguard and the first to enter Xiongxian County, and the governors Xu Kai and Pan Zhong were stationed in Hejian and Mozhou, and the main force of the Chinese army moved to Zhending. For a time, hundreds of thousands of officers and soldiers marched towards the northern frontier with banners all over the field.

The spies sent the news to Beiping, and Liu Shaoyang and other Wuxingmen Zhou Wu old departments heard that Geng Bingwen was in command of the Northern Expedition, and remembered that the two Huai were shocked and hated all undercurrent, and they were gearing up to seek revenge.

Zhu Di gathered the crowd to raise countermeasures, and Zhang Yu wanted to make a preamble: "More than 10,000 men and horses of Yang Song, the vanguard of Geng Bingwen's army, have been stationed in Xiongxian County, and it is only 200 miles away from Beiping City. The last general asked for battle to lead 10,000 troops to break it first, if he can't take Xiongxian and come to see him!"

Liu Shaoyang remembered that Geng Bingwen had led his troops to suppress and slaughter countless of his former brothers in the Five Elements Gate. For a while, he was filled with indignation, and blurted out: "The kid and that Geng Bingwen have an old blood debt to calculate, and it only takes 3,000 men and horses to seize the Xiongxian County, and it will definitely be able to destroy the Southern Army and defeat that Geng Bingwen's majesty!"

Zhang Yu once regarded Liu Shaoyang and others as reckless and disdainful, and then saw with his own eyes that Liu Shaoyang's scheming and martial arts are rare in the world, and all the people in the Five Elements Sect are heroic, so he dispelled the idea of contempt. But at this moment, when I heard Liu Shaoyang say that only 3,000 soldiers and horses were needed to kill the vanguard of the Southern Army, I still didn't believe it in my heart, and I couldn't help but say: "There are more than 10,000 soldiers in the high wall of Naxiong County, and General Liu's words are too big!"

Zhu Di also felt that it was too risky to only lead 3,000 soldiers, so he couldn't help but contemplate and persuade: "3,000 men and horses are too few, and the virtuous brother must not be rash!"

Liu Shaoyang saw that everyone was wrong, and immediately said: "This time the battle is not a big boy, but now that August 15 is approaching, the southern army is far away and has won many troops, so it will definitely be negligent in its defense." I first marched to Sanglou with 3,000 men and horses to hide and hide, and waited until the Mid-Autumn Festival moonlit night to take Boxiong County by surprise. Besides, this time I have asked the craftsmen to make several high-tower chariots, and at that time, the ballistas will be fired from above the castle, which should be even more helpful!"

When everyone heard him say that they wanted to build a tall tower car, they wanted to take a look, and Liu Shaoyang immediately introduced everyone into the manufacturing workshop in the headquarters camp. Everyone was full of anticipation, but they only saw some wooden pillars and wedges piled up on the ground, different sizes, wrapped in leather. Even the axles of the same size were not installed, and they couldn't help but shake their heads secretly.

Liu Shaoyang smiled indifferently and didn't care, and ordered more than a dozen craftsmen to be summoned to load the tower car. When everyone looked at it, they saw that these more than ten people each took the machine and the reciprocating buckle, and it only took a quarter of an hour of effort to build a tall wooden building with a height of three zhang and a length of five zhang.

Zhu Di was amazed and looked closely, only to see that the wooden building was covered with thick leather iron sheets to shield the enemy, and there were several pairs of wooden wheels embedded below to move. There is a wooden ladder to transport people and things, and it is really a siege tower car that is very clever and ingenious
