When the attack and defense of Jiading City was in full swing, the Thunderbolt army did not move. This is not that Ouyang Xuan wants the Meng army and the Jiading army to fight and lose both, and then clean up the mess by himself, but is waiting for the opportunity. To be precise, it is waiting for the arrival of the Mongolian army in Chengdu. Only by crippling the Mongolian army and navy again can we solve the worries of going south to reinforce Jiading. Last year, Peng Shanshui Zhanle Quan'an led the naval army to defeat the Mongolian army, which greatly damaged its vitality. After that, although Liu Heima built a lot of ships and trained and recruited many sailors, his strength was far less than before, and he did not dare to go south. After all, the Mongolian army also knows that their own navy is not only small and inexperienced, but it is just a fish belly in front of the Thunderbolt army.

The reason why the Mongolian army dared to go south again this time was because of a letter written by Niu Lin to Liu Heima. In the letter, Niu Xuan said that he besieged Jiading in three ways and would succeed in one fell swoop, but the Meizhou Navy was helpless against the Jiading Navy and was quite restrained in the war. In the letter, he assured Liu Heima that his fears of the Thunderbolt army had now been resolved—that Pengshan City had secretly surrendered to him. After the surrender of Pengshan City, the Mongol army could not only block the river with the artillery in the city, but also obtained the surrendered naval gunboats, which could completely prevent the Thunderbolt army from attacking from upstream. The Mongolian navy went south to Jiading and together with the Meizhou navy, it will be able to defeat the Jiading navy. Without the support of the navy, Jiading City will be taken quickly.

Liu Heima is not stupid, he knows that Peng Shancheng's secret surrender is not reliable, you know, in the past two years, he has also recruited the Thunderbolt Army and its generals many times, but it has no effect and even folded a lot of spies sent. Throughout the rise of the Thunderbolt Army, those who have surrendered have been small shrimps such as Chang Yuan of Jiangyuan City, and no middle and senior officers have ever surrendered. It's just that at the moment when the two khans are fighting, it is extremely important to maintain a neutral New Zealand, if the navy is dispatched to help it, not only can it win him to join Kublai Khan, who he supports, but also get a share of the battle of Jiading, this risk is worth taking. In general, there were many Song troops who surrendered, but there were only a very small number of people who repeatedly surrendered and surrendered by deception.

Niu Lin naturally knew that the surrender of Pengshan City was not as sworn by Liu Daer as he claimed. The Mongol army has always looked down on the new annexed army, in addition to the reason for its low combat effectiveness, but also because these armies have no faith at all and often betray impermanence, so he did not fully believe in Liu Da'er's words. It's just that now is the time for the water army, so you have to take the risk and give it a try. If Pengshan City really surrenders, not only Jiading will be determined in the near future, but it can even wipe out the Thunderbolt army in one fell swoop. As for the water army to take risks? That is Liu Heima's water army, the so-called "dead friends do not die poor road". Liu Heima suffered better losses, which was equivalent to Kublai Khan's strength was also weakened. Niu Lu is neutral on the surface, but he supports Ali Buge in his heart.

"Things gather by like, people by groups", Liu Daer can become Yu Xing's confidant and govern Meizhou, and he is also an official oilman. Although Zhou Jianshen wrote a letter of surrender with blood seals and a roster of participating officers and soldiers, and even sent over the strength of Pengshan City, the situation of the warships and the deployment map, Liu Daer was still not at ease. Before going south to Jiading, he sent several henchmen to inspect the situation, and these henchmen saw that the banners of the Meizhou Army and the Mongolian Army were raised in Pengshan City, and that an official document accusing Ouyang Xuan and the Thunderbolt Army was posted at the entrance of the county ya, and they even went to the gunboats on the dock to inspect the spot, and they were already eight or nine points convinced.

These henchmen relayed Liu Da'er's request: hand over the Great Seal of Pengshan County, take hostages to the Mongolian army, and send officials from Meizhou to take over the city. Zhou Jianshen was furious at this request, claiming that the Great Seal could be handed over, but the hostages and the matter taken over by Meizhou would never be agreed. One is that he has no relatives, and the other is that the Mongolian army has promised him to be the commander of Pengshan County, how can he go back on his word? and cross-examined whether Meizhou had been taken over by the Mongolian army and whether it had taken hostages, so that Liu Daer's henchmen were speechless, so they had to return to Meizhou and report to him truthfully.

Liu Daer knew that he was at a loss, and several henchmen received a lot of Zhou Jianshen's property, and they also spoke to Zhou Jianshen, and immediately believed that Zhou Jianshen not only surrendered with his infantry battalion, but also encouraged the naval army and the officials in the city to surrender together. Now his worry is how to settle these surrendered Thunderbolt Army officials, you must know that he has already promised the positions of Meizhou counties to his generals, and even Zhou Jianshen's Pengshan County Commander position has been secretly promised to his henchmen. His wishful thinking was that after controlling Pengshan City, he seized Zhou Jianshen's military power and transferred him to an idle position, which not only sought benefits for his henchmen but also solved hidden dangers, and also obtained an elite army, which can be described as killing three birds with one stone.

Thinking that he was about to become the lord of Jiading, Liu Da'er was happy in his heart. At that time, he will have two (fu) states and eleven counties, plus the thunderbolt weapons obtained from the Pengshan City army, he can compete with the Thunderbolt army in the north, and he can seize the land of Xuzhou in the south, not only Cao Zhizhou will also rely on his own snort, even Niu Ling will also think highly of himself, if he accepts the treasure of beauty from the Mongolian Great Khan, maybe he can also become a hereditary Han army marquis like Wang Dechen, and the children and grandchildren of the family can also enjoy the glory and wealth.

Liu Da'er's wishful thinking crackled, but he didn't know that Cao Zhizhou was not a good type. Although he discussed with Liu Da'er that the Meizhou army would take over Jiading after the capture of Jiading, he knew how the Mongolian army would tolerate Liu Da'er's sitting on the throne, and would inevitably take measures to limit his power in the future, which was why he dared to promise the Yibo tribe and the Qingqiang tribe to settle in Jiading Meizhou, because the Mongolian army was absolutely happy to see other forces to check and balance Liu Da'er. What's more, the Thunderbolt army will not be willing to let Jiading Meizhou fall into the Mongolian army, and the two sides will inevitably fight endlessly. This is his deliberate weakness and concession in front of Liu Daer and Niu Ling, which is really a plan by the director to drive away the wolf. When both sides are defeated, it is the time when the Yazhou army reaps the benefits.

All sides of the Mongol army attacking Jiading are calculating their own interests, and the Thunderbolt army is also calculating how to achieve the greatest result at the lowest cost. The Mongolian army has not been able to shrink before, and the waterway leading to Chengdu in Pengshan City is not wide, and the Mongolian army has arranged a lot of fortifications on both sides of the river, and the risk of attacking is too great, the best way is to lure it out, and Pengshan City is the bait. In order to make the fraudulent surrender more realistic, the General Staff took great pains to coordinate the fraudulent surrender operation. The letters sent to Liu Daer and the roster of officers and soldiers are all real, and the blood marks on them are also real - dog blood, for which the staff department also killed a dog. The big seal of Pengshan County that Zhou Jianshen promised to give is also true, but the Thunderbolt Army doesn't need this thing at all.

The Pengshan City troops, warships, and defense maps sent to the Mongolian army are half-truths and half-truths, after all, these things are in full view, and they can't deceive people by completely fake. As for the official document posted at the entrance of the county government attacking Ouyang Xuan and the Perak Army, it was written by Cao Zhizhou, which was a letter he had written to a high-ranking official in the DPRK and China, but it was intercepted by the Perak Army halfway, and the General Staff Department used it with slight modifications. Before using this letter, Huang Dagen specially asked Ouyang Xuan's opinion, to which he replied: "Regardless of the means, only talk about the result." To him, being scolded is just a trivial matter, as long as it can achieve the goal of beating the enemy.
