As soon as Dou Kang finished speaking, Qin Hui, who had been on many missions to Hebei, added: "According to detailed reports in Hebei, after Yang Gao wiped out Yuan Chu's army, he reworked tens of thousands of prisoners and sent them to Ye County. , built forts and dug deep trenches. They also sent generals Wang Zhongsi, Fu Youde, rebel generals Guo Zhiyun and Pei Xingyan to lead their troops south, intending to attack Qin Qiong's troops in Qingzhou and destroy the troops of Zhu Yuanzhang's son Zhu Di who were stationed along the Yellow River."
Li Shimin heard this and immediately asked: "What are the movements of Yang Gao's main army?"
Although he was Li Jiancheng's confidant, Qin Hui still answered Li Shimin respectfully in the main hall: "Back to His Majesty the King of Qin, it was reported that after Yang Gao defeated Yuan Chu's army, he did not take advantage of the situation to pursue Zhu Yuanzhang who fled west, but went all the way north to recover Arriving at Hejian Qinghe and other places, the Sui army's general Gao Chong Yue Yun led five thousand fine cavalry to march day and night. Judging by the days, they have probably entered the territory of Youzhou now."
"It seems that the situation in Youzhou is already very tense, and Yang Gao can actually give up the good opportunity to pursue Zhu Yuanzhang and let him threaten his rear." Li Jiancheng said slowly.
Li Shimin said calmly: "After Temujin put down the rebellion of Yelu Abaoji, he personally led an army of 100,000 people to march westward to Youzhou to join forces with his son Tuolei. Together with the Jurchen army defeated by Wanyan Agu, the entire territory of Youzhou There are more than 300,000 foreign troops and horses. Luo Yi and Zhang Xun alone may not be able to do what they want.
As early as the last years of Daye, Youzhou had cut off contact with Jiangdu due to the rampant bandits in Hebei. Although Luo Yi was still under the banner of the Sui Army, he was actually an independent party. Temujin and Wanyan Aguda invaded Youzhou for several years. The people of Youzhou suffered from war and were already deeply disappointed with Luo Yi. If Yang Gao abandons Zhu Yuanzhang at this time and saves Youzhou first, he will definitely win the hearts and minds of the people in Youzhou and truly capture Youzhou. "
"In this case, my father, I think this is a once-in-a-lifetime opportunity for us in the Tang Dynasty."
Li Jiancheng's face was filled with joy and he said loudly: "Temujin has been in the desert for many years. He has millions of armors and countless warriors under his command. He also has the help of the Jurchen Wanyan Aguda. If we, Datang and Zhu Yuanzhang are added to it, the four families will be able to join forces. Annihilate all the hundreds of thousands of Sui troops in Youzhou."
"Your Majesty, what His Royal Highness the Crown Prince said is absolutely true."
Qin Hui immediately echoed: "Wei Chen believes that at this time, we should immediately assemble the Twelve Guards Army in Guanzhong, join General Chai Rong and Zhu Yuanzhang from Bingzhou, and march westward to Youzhou. Together with Temujin and Wanyan Aguda, they will annihilate them all. Yang Gao’s army of hundreds of thousands."
"Yang Gao'er's tyranny is unpopular, and the gentry in Hebei will definitely not be convinced."
Pei Ji, the prime minister who belonged to Li Jiancheng's faction, also came out and said: "Your Majesty can send people to Hebei to contact the major noble families, and they can come forward to stir up civil strife in Hebei and cut off Yang Gao's retreat."
"Your Majesty, this is truly a once-in-a-lifetime opportunity. Please give your Majesty the order immediately."
At this time, not only several prime ministers of Li Jiancheng's faction, but also Dou Kang, who was loyal to Li Shimin, also agreed.
Just when Li Yuan was about to issue an order, Li Shimin objected loudly: "Father, you can't do it. If you follow your elder brother's idea, our Tang Dynasty will be in danger!"
Li Jiancheng's face suddenly turned livid when he heard this, and he immediately yelled: "Second brother, what do you mean?"
Li Shimin snorted coldly and said, "I just stated a fact!"
"you..."
Li Jiancheng wanted to say something more, but was interrupted by Li Yuan with a wave of his hand: "Erlang, why do you say that sending troops to Youzhou at this time will be detrimental to the Tang Dynasty?"
"Temujin and Wanyan Aguda are both foreigners. Since ancient times, the invasion of northern nomads has brought a heavy burden to the people of the world. If we send troops to Youzhou at this time, we will make it clear that we stand on the same line as Temujin and Wanyan Aguda. This is one of the things that would disappoint us."
Li Shimin took a breath and continued: "Second, even if we send troops to join forces with Temujin, Zhu Yuanzhang and others to defeat the Sui army and seize Youzhou and Hebei. But what should we do next? We in the Tang Dynasty will send troops and food. Can’t we give up the territory we conquered to Temujin and Zhu Yuanzhang?”
"But now that we have formed allies with Zhu Yuanzhang and Temujin, can't we sit down and talk after defeating the Sui army and divide our respective territories?" Li Jiancheng couldn't help but say.
Li Shimin sneered disdainfully, "Brother, throughout the ages, the most unreliable people in the world are the so-called allies. If we really defeat the Sui army, Temujin and the others will join forces to deal with us without hesitation."
"Erlang is right."
Li Yuan nodded and said: "Once the Sui army defeats Hebei, our Tang Dynasty will become Temujin's biggest threat. According to this person's character, he will not hesitate to turn against us and start a war."
"Father, Holy Ming!"
Li Shimin cupped his hands and continued: "Temujin, Zhu Yuanzhang, and Wanyan Aguda are all heroes with the world in mind. Although they are now united with us because of the power of the Sui army, they will never surrender to the Tang Dynasty. So. , why don’t we use Yang Gao’s help to weaken these potential enemies?
In addition, even if we can destroy Yang Gao's hundreds of thousands of troops in Youzhou, Yang Gao still has hundreds of thousands of troops in the Central Plains and Bashu. But our main army of the Tang Dynasty is very likely to fall into disputes with Temujin and others after that. Guanzhong is empty. Will Yang Gao have the desire to attack Guanzhong? "
Li Yuan couldn't help but nod his head in approval: "What Erlang said is reasonable, what Erlang said is absolutely true!"
"Father, I think Youzhou is now a big quagmire. Once you get in, it will be difficult to get out. Therefore, we can lobby the Hebei nobles to come forward to disrupt Yang Gao's rear, as Mr. Pei said, or we can give Zhu Yuanzhang Others will provide some food and grass support, but we must not send the main force to Youzhou!"
Li Yuan was obviously convinced by Li Shimin and immediately asked: "In Erlang's opinion, what should Datang do next?"
"Bashu!"
Li Shimin said eloquently: "I believe that the main force of our army should be sent to Bashu next, and we will try our best to regain the lost territory of Bashu."
"I thought the second brother had any clever tricks up his sleeve?"
Li Jiancheng finally seized an opportunity to counterattack Li Shimin, and said with a sneer: "Bashu has many dangerous roads, and it has been a place that is easy to defend and difficult to attack since ancient times. What is the ability of Li Jing who is in charge of Bashu? I think about it when he was in Mayi County many years ago , Second brother has already seen it. If we throw the main force of the Tang Dynasty into Youzhou, we will be deeply involved in the quagmire of war, but south of Bashu, haha, second brother, aren't you afraid of wasting money and food in the end?"
"Bashu is easy to defend but difficult to attack, and Li Jing is indeed a famous general in the world."
Li Shimin said solemnly: "But I planted a surprise force in a place where Li Jing didn't expect it. I will definitely kill Li Jing by surprise!"
"Oh? What kind of surprise troops did Erlang prepare?" Li Yuan was stunned when he heard this, and asked immediately.
Li Shimin smiled slightly and said, "Father, have you ever heard of Tubo?"
