The fierce battle in Luoyang involved the nerves of all parties, and they were paying close attention, and at the same time, envoys were sent to secretly contact each other, faintly forming an alliance.

Jinyang City.

Li Yuan was worried, because the development momentum of Dahua was too fast, since occupying the Guanlong area, with the danger of Hangu Pass, it completely became the posture of the Qin State back then, opening up the connection between the Guannai and the Western Regions, and reopening the Hexi Corridor and the Silk Road, making the situation in the Guannei stable and economic development far more than these princes in the Central Plains.

Li Tang currently only has three counties, including Taiyuan, even if he captures Yanmen County and takes root here, but the population is sparse and the economy is weak, it is not easy to develop, let alone unify the princes.

He has a sense of powerlessness that is declining and the rivers are declining.

"Luo Cheng, the situation of the Li family has come to this point, and you have harmed people a lot!" Li Yuan now has a deep hatred for Luo Cheng, originally the Li family had already occupied Chang'an City, as long as it developed, the Tang Kingdom would be able to become powerful, and it would not be a problem to sweep the princes of the Central Plains in the future, but at this moment, the hope became slim.

Li Jiancheng proposed in the palace of the imperial book: "Father, we can't watch Luoyang give it to Dahua like this, once the eastern capital is lost, how many nobles and relics of the Great Sui there, talents, etc., will be attributed to Dahua, that is the core of the world, take this as a strategic point, spread around, the next target is Dou Jiande, and then we are in the northwest of Jinyang, when the time comes, north of the Yellow River, there will be no princes who can exist safely." ”

Li Yuan nodded and said, "Why don't I understand this truth?" But as soon as our military strength is insufficient, we still need more than 100,000 people, we need to contend with Liu Wuzhou, and we also have to guard against the Dahua garrison in the land of Luochuan, which is suddenly inserted into the land east of the river, and it is too late to defend, how can we have extra troops to travel a long way to rescue Luoyang? Moreover, the route is far away, and the supply of grain and grass is also a problem, as long as Dahua sends men and horses to cut off the grain route of our army on the way, the Tang army on the front line will be defeated without a fight! ”

"One more point, that is, the soldiers of our army, composed of the Guanzhong Army and the people of Fendi, who is willing to leave their hometown, go to Luoyang to participate in the war, and fight with hundreds of thousands of elite troops in Dahua, isn't that equivalent to a moth to the fire, it is conceivable that when the army is disheartened, go to 50,000 people, I am afraid that it will be wiped out before it reaches the outside of Luoyang City."

"What then?"

Pei Lin said at this time: "His Royal Highness the Prince, don't worry, the minister and His Majesty discussed it yesterday, and it is imperative to deal with the prestige of the Turks, reconcile the dispute between Liu Wuzhou and our Tang State, temporarily stop the war, take Yanmen Pass as the boundary, do not negotiate with each other, and form an anti-China alliance!" The three parties each sent some soldiers, or materials, war horses, etc., to provide Dou Jiande's Xia State, prompting the Xia army to move south, only Dou Jiande's current strength has two or three hundred thousand, and the land of Hebei, the closest to Luoyang, as long as the Yellow River is crossed, take Xingyang, and use this as a springboard, you can break through the Tiger Prison Pass, approach Luoyang, and then make Dahua unable to attack wholeheartedly, and was forced to fight head-on with Dou Jiande's army outside Luoyang! ”

"At that time, the Chu State and the Liang State in the south will also send troops, and our Tang State will pass through Mengjindu and Fenglingdu from Hedong, disturb Dahua's grain route, and cut off its military source channel, which will make Dahua's front army suffer from the enemy and be forced to withdraw to Hangu Pass, forming a situation where the princes join forces to resist China!"

Li Jiancheng nodded slightly, but he still had concerns: "But Dou Jiande is also a hero, how can he take the lead in sending the main army to fight Dahua?" Without enough interests and drives, Xia Guo will not send troops easily. ”

Li Yuan said: "Yes, Xia Guo also has its concerns, because behind him, is Luo Yi's Zhuojun garrison, and there are currently close to 200,000 troops, Luo Yi, Xue Shixiong, and Mai Tiecane are all former Great Sui generals, once they attack the rear of Xia from behind, it will also endanger the foundation and capital of Xia State, because of this, Dou Jiande is in a dilemma, he is most worried about the loss of Luoyang, because Wang Shichong is dead, the next target is him Dou Jiande, this is a clear thing!" ”

"Therefore, we must eliminate the concerns of Xia Guo in this regard, and hope to invite Shibi Khan to lead the army into the area of Yanshan, intimidate the garrison of Zhuo County, so that Luo Yi will not dare to act rashly, and in addition, send people to send a letter to the Goguryeo people in Liaodong, continue to harass Liaodong County, drag the Liaodong garrison, and cannot pull out to the south. In this way, Dou Jiande dared to lead the army south, confront Dahua in advance, and fight to the death! ”

Only then did Li Jiancheng understand the key, nodded and said: "With this arrangement, Xia Guo has no worries, and he may really be able to lead the army to take it and rescue Luoyang." ”

Li Yuan stroked his beard, his eyes flashed, and analyzed: "Yes, although Wang Shichong is a villain, he has no ambitions, he only wants to hold the eastern capital and continue to be his soil emperor, for other princes, there is no competitiveness, and he is the first target of Dahua's attack, so the princes of all parties hope that Wang Shichong, a villain, will always be alive, and Zheng Guo will always exist, so he can stop Dahua's footsteps!" ”

Li Jiancheng suddenly said: "Erchen understands, the current importance of Zheng Guo is equivalent to the Warring States Period, the existence of Korea is the first obstacle to prevent Qin from going east, as long as it is intact, there will be no future to annex the Six Kingdoms!" ”

"Exactly!" Li Yuan nodded, the current situation is the same as the pattern of the Warring States Period, and the same is true of the Chu-Han Dispute period.

Occupy Guanzhong, with a geographical advantage, only it attacks others, and it is difficult for others to attack it!

Then you can develop steadily in the rich land of Guannai, and the speed will be superior to that of the Central Plains, because the Central Plains is a flat river, lacking the natural danger of mountains and rivers, and the princes attack each other, and they have not been able to be satisfied with production, which is lagging behind people.

Pei Lin arched his hand and said: "Your Majesty, without further ado, this matter should be grasped quickly, and the minister will arrange envoys to contact the Turks, Liu Wuzhou, Dou Jiande, Xiao Liang, and Chu State!" ”

Li Yuan arranged: "Well, the Turkic side is particularly important, Pei Qing, you will personally send the Turkic envoy." ”
