After receiving the news of the loss of Yangping Pass, Zhang Lu was stunned, originally thinking that Yang Bai would go to guard Yangping Pass, even if he was defeated, it should not be a big problem to resist for three or five months, but he never thought that Yang Bai would not even hold it for three or five days. Yangping Pass is the only natural danger in Hanzhong, Yangping Pass is lost, there is almost no danger in Hanzhong, and there are not many soldiers and horses in Zhang Lu's hands to mobilize.

Zhang Lu can be regarded as an out-and-out god stick, dressed in the cloak of Taoism, coercing the people to demagogue, but he is smarter than Zhang Jiao in that he is not openly an enemy in the court, taking advantage of the opportunity of his mother is Liu Yan's concubine, serving as the governor of Yi Sima, and developing his own power in Hanzhong, because believers enter the Tao and need to pay five buckets of rice, so Zhang Lu's Taoism is also called five buckets of rice. Zhang Lu has always disobeyed Liu Yanyang and cultivated party henchmen, and later turned against Liu Zhang, seized Hanzhong, and became strictly self-reliant.

Liu Zhang couldn't help him, and Cao Cao dealt with him flawlessly, so Zhang Lu was very free in Hanzhong for some years, and the frog at the bottom of the well felt that the sky was so big, because what it saw was that piece of sky, Zhang Lu had nothing to do in Hanzhong for many years, and he thought that this one-third of an acre of land in Hanzhong was his world, and no one else could touch it. Liu Ze marched into Yizhou, he also mistakenly thought that he had a chance to get a piece of the pie, and wanted to take the opportunity to take the Jiameng Pass, but the result was that he didn't eat the mutton and provoked a body, and the Jiameng Pass was not taken down, but he was burned, not only lost his younger brother Zhang Wei and 50,000 troops, but also the Jing soldiers committed the territory, and even the Yangping Pass was lost, and Zhang Lu couldn't help but regret it.

Lord Bo Yanpu said: "Yangping Pass is lost. Nan Zheng has few soldiers, and he can't stop the Jing army from attacking, why don't the lord follow Liu Cong of Jingzhou and Liu Zhang of Yizhou, for the sake of hundreds of thousands of people in Hanzhong, sacrifice Hanzhong and surrender, Liu Zesu takes benevolence and righteousness as his heart. The lord is also a high-ranking official. ”

Zhang Lu hesitated, to be honest, Zhang Lu couldn't see the situation in front of Hanzhong, but when he thought of surrendering the city, his heart was like a knife, so he hesitated again and again.

Strategist Yang Song said: "Although Hanzhong can't hold it, why should it surrender to Liu Ze?" Under Fang today, the most powerful person is Cao Cao, the king of Wei, who coerced the Son of Heaven to order the princes. The lord is Cao Cheng's personal grant of Zhenyi Zhonglang Hanning Taishou, this is not the king's land under the whole world, the guest of the land is not the king's minister, the king of Wei represents the righteousness of the court, the lord surrenders to the king of Wei, it cannot be regarded as a surrender, as long as the king of Wei enters Hanzhong, why not be afraid of Liu Ze's attack. The lord's wealth and nobility are also indispensable. ”

Cao Cao didn't have time to pay attention to Hanzhong. I don't think that I don't care about Hanzhong, after Cao Cao broke Yuan Shao in the fifth year of Jian'an, he added Zhang Lu as the general of Hanning Taishou Zhenyi Zhonglang, and Yang Song, as a messenger sent by Zhang Lu, went to Xudu to contact Cao Cao, and received a lot of bribes from Cao Cao. On the issue of descending Liu or Cao, Yang Song is naturally still inclined to Cao Cao.

Yan Pu disagreed, and said: "Cao Cao is a national thief, and he has been usurping the Han Dynasty for a long time, if the lord surrenders to this person." If he is an official under his account, he will inevitably bear the name of a rebel in the future. Liu Jing, the king of Jing, is sincere and righteous, and he is a righteous teacher, why does the lord give up the pearl and seek the dark land? ”

Zhang Lu pondered undecided, in fact, he didn't care about being a rebel, the key is that since he wants to surrender, he has to find a long-term meal ticket, and now the two strongest candidates in the world are Cao Cao and Liu Ze, who can annex who will eventually dominate the world, Zhang Lu has no bottom in his heart, no matter who surrenders, Zhang Lu didn't think about surrendering twice. For example, if you surrender to Liu Ze, and in turn Liu Ze is destroyed by Cao Cao, you can't surrender again. Since Zhang Lu has to make a choice, Zhang Lu must definitely make a wise choice.

Zhang Lu didn't say anything, but Yang Song couldn't hold his breath and sneered: "Lord Yan Bo is so impatient to surrender to Liu Ze, could it be that Lord Yan Bo took Liu Ze's benefits, so he is here to encourage the lord?" Yang Song hit a rake, and the spearhead was pointed at Yan Pu.

Yan Pu's face was swollen and red, he didn't expect Yang Song to be unscrupulous and slander himself, and said angrily: "Yang Song, you deceive people too much, when did I take Liu Ze's bribe?" Now that the Jing army is pressing, I am only saying this for the sake of hundreds of thousands of people in Hanzhong, you actually ...... How unreasonable! ”

Yang Song smiled and said: "Whether you take the benefit or not, only God knows, but don't forget, the second general Zhang Wei died in the hands of Liu Ze, Yang Ren, Yang Bai, Yang Ang, and seventy or eighty thousand Hanzhong soldiers, who were killed?" This blood debt has not been paid, but Lord Yan Bo has built a yì lord and Liu Ze, who is not in the same sky, shook hands and made peace, what are your intentions? ”

Yan Pu said angrily: "Lord Mingjian, if you have the slightest heart in your humble position, you will be sent by heaven!" ”

Zhang Lu didn't mean to blame Yan Pu, anyway, now it's a matter of choosing one of the two, there seems to be no third way to go, emotionally speaking, he is more willing to take refuge in Cao Cao, after all, his relationship with Cao Cao has always been good, and he has also heard of Liu Ze's iron-fisted methods, after surrendering Liu Ze, there is no good fruit to eat Zhang Lu has no score in his heart. But the real problem in front of us is that it is difficult to quench the thirst of the near water, after Liu Ze captured Yangping Pass, it was not far from Nanzheng, and Cao Cao was far away from thousands of mountains and rivers, I am afraid that before Cao Cao's reinforcements arrived, Liu Ze's army had already attacked the city of Nanzheng.

Regarding Zhang Lu's question, Yang Song was calm. "Don't worry, the lord has arrived in Chang'an, and Han Sui Ma Chao fought in Guanzhong, and between Hanzhong, it is just a Qinling Mountains, the lord can send someone to Chang'an immediately at this moment, hand over the letter of surrender, and say that the Han Dynasty is in shape, and Cao Gong will definitely send elite soldiers to help. As for the lord's concern that Liu Ze will march from Yangping Pass to Nanzheng, the lord can also rest assured that there is still a critical place in the west of Nanzheng, that is, Dingjun Mountain, and he is willing to lead a team of soldiers and horses to Dingjun Mountain to block Liu Ze, and when Cao Gong's reinforcements come, they will join forces inside and outside, and Liu Ze will be broken. ”

Zhang Lu nodded in agreement, immediately repaired a letter, and sent a messenger to Chang'an to meet Cao Cao, stating that he was willing to return to Cao Cao from now on, and at the same time explaining that Hanzhong was in danger, and asked Cao Cao to send reinforcements immediately to ensure that Hanzhong was not lost.

After sending the envoy to Chang'an, Zhang Lu allocated half of the men and horses to Yang Song from the remaining more than 30,000 defenders in Nanzheng, and ordered Changqi to be the vanguard of the front and rushed to Dingjun Mountain to block Liu Ze.

After the end of the battle of Xuzhou in the tenth year of Jian'an, Cao Cao got five counties of Xuzhou in addition to Guangling County, which can be described as brilliant results, and the only thing that made Cao Cao sad was that Guo Jia died in Xiapi City, which made Cao Cao sleep. Since seeing the power of the red-coated cannon, Cao Cao was very interested in the artillery and was determined to imitate the same weapon, Cao Cao immediately summoned the top craftsmen in China, including the master craftsman Zheng Hun, and asked them to work together to develop an artillery of the same power in the shortest possible time.

Zheng Hun and the others were at a loss, although they gathered the best craftsmen in the world, they knew nothing about artillery, and they could not master this technology at all by watching from a distance, let alone imitate it. Zheng Hun proposed to Cao Cao that as long as he could obtain a physical object, even if it was a defective product, he could also make a cannon from a gourd.

Cao Cao was dumbfounded this time, knowing that Liu Ze regarded these artillery pieces as treasures, and had no chance to snatch them back, and these cannons were extremely heavy, even if there was no one to guard against them, it was almost impossible to steal one.

Liu Ze took the initiative to give up Xuzhou and handed it over to Sun Quan, Cao Cao was not polite at this time, he was still afraid of artillery when he beat Liu Ze, but he was not so careful to fight Sun Quan, and after several months of strong attack, Cao Cao finally took Xuzhou, and at the same time he also got an unexpected joy and found the remains of an artillery piece from the firearms battalion evacuated by the Jing army.

This artillery was damaged by the Jing Army's explosion in use, and because the loss was too great and there was no value in repair, it was abandoned by the artillery after the battalion and used as a pile of scrap metal. Zheng Hun was like a treasure, and swore that he would definitely be able to imitate the exact same artillery. (To be continued......)
