The fierce battle in Luoyang involved the nerves of all parties and was paying close attention. At the same time, envoys were sent to secretly contact each other, forming a vague alliance.

Jinyang City.

Li Yuan was worried because Dahua's development momentum was too fast. Since occupying the Guanlong area, relying on the danger of Hangu Pass, it has completely become the Qin State's position at that time. It has opened up the connection between the pass and the Western Regions, and reopened the Hexi Corridor and the Silk Road, making the situation within the pass and the economic development far exceed that of the princes of the Central Plains.

Li Tang currently only had three counties including Taiyuan. Even if they captured Yanmen County and took root here, they had a sparse population and weak economy. It would be easier to develop, let alone unify the princes.

He felt powerlessness as he was falling and rivers were falling.

"Luo Cheng, the situation of the Li family has come to this point, and you are a great harm to others!" Li Yuan now has a deep hatred for Luo Cheng. Originally, the Li family had occupied Chang'an City. As long as it continued to develop, the Tang Kingdom could become powerful. It would be no problem to sweep the princes of the Central Plains in the future. But at this moment, hope became slim.

Li Jiancheng proposed in the Imperial Book Hall: "Father, we can't watch Luoyang give it to Dahua like this. Once the Dongdu is lost, many nobles, the remnants of the Great Sui Dynasty, talents, etc. will all return to Dahua. It is the core of the world. Taking this as a strategic point, it spreads around. The next target is Dou Jiande, and then we are northwest Jinyang. At that time, there will be no princes who can exist safely north of the Yellow River."

Li Yuan nodded and said, "I don't understand this principle? But at first, our military strength is insufficient, and we still need more than 100,000 people. We need to compete with Liu Wuzhou and guard against the Dahua garrison in Luochuan. It suddenly penetrated into the Hedong area. It was too late to defend. How could there be extra troops to rescue Luoyang? Moreover, the route is far away, and food supply is also a problem. As long as Dahua sends people to cut off our rations on the way, the Tang army on the front line will collapse without fighting!"

"There is another point, that is, our soldiers are composed of Guanzhong Army and Fendi people. Who would want to leave their hometowns and go to Luoyang to participate in the war and fight with hundreds of thousands of elite troops in Dahua? Isn't that the moths hit the fire? It can be imagined that by the time the morale of the army is dispersed and 50,000 people will probably be destroyed before the Luoyang city."

"What should I do?"

Pei Ji said at this time: "Your Highness, Your Majesty, I have discussed it with Your Majesty yesterday. The top priority is to deal with the dispute between Liu Wuzhou and our Tang Kingdom with the help of the prestige of the Turks, and temporarily stop the military and warriors, and use Yanmen Pass as the boundary to form an anti-China alliance! Some soldiers, or materials, war horses, etc. of the three parties provide Dou Jiande's Xia Kingdom, prompting the Xia army to move south in a large scale. Only Dou Jiande currently has 200,000 to 300,000 troops, and the land in Hebei is closest to Luoyang. As long as you cross the Yellow River and take Xingyang, using this as a springboard, you can open up Hulao Pass and approach Luoyang, and then make Dahua unable to attack with all his heart, and be forced to fight against Dou Jiande's army head-on!"

"At that time, the Chu and Liang states in the south will also send troops. Our Tang state traveled from Hedong to Mengjin Ferry and Fengling Ferry to numb Dahua's grain channels and cut off its source of troops. It will cause the army in front of Dahua to be attacked from both sides and be forced to withdraw back to Hangu Pass, forming a situation where the princes unite to resist China!"

Li Jiancheng nodded slightly, but still had concerns: "But Dou Jiande is also a hero. How could he be the first to send the main army to war with Dahua? Without enough interests and drive, the Xia Kingdom would not send troops easily."

Li Yuan said: "Yes, Xia State also has its concerns, because behind him is Luo Yi's Zhuo County garrison, and currently has nearly 200,000 troops. Luo Yi, Xue Shixiong, and Mai Tiebang are all former generals of the Sui Dynasty. Once they attack the rear of Xia State from behind, they will endanger the foundation and capital of Xia State. Because of this, Dou Jiande was in a dilemma. He was most worried about the loss of Luoyang because Wang Shichong was dead, and his next target was Dou Jiande. This is obvious!"

"Therefore, we must eliminate the concerns of the Xia State in this regard. We hope to invite Shibi Khan to lead the army into the Yanshan area and intimidate the garrison of Zhuo County, so that Luo Yi dared not act rashly. In addition, he sent people to send letters to the people of Goguryeo, Liaodong, and continued to disturb Liaodong County, and delayed the garrison of Liaodong, so that he could not pull out the south. In this way, Dou Jiande dared to lead the army south, confront Dahua in advance, and decide his life and death!"

Only then did Li Jiancheng understand the key and nodded and said, "In this arrangement, Xia State has no worries. Maybe he can really lead the army to save Luoyang."

Li Yuan stroked his beard, his eyes flashed brightly, and analyzed: "Yes, although Wang Shichong was a villain, he had no ambitions and only wanted to defend Dongdu and continue to be his local emperor. For other princes, he had no competitiveness, and he was the target of Dahua's attack. Therefore, all princes hoped that Wang Shichong, a villain, would be alive and that Zheng State would always exist, so that Dahua could block Dahua's footsteps!"

Li Jiancheng suddenly said: "My son understands that the current importance of Zheng State is equivalent to the Warring States Period. The existence of South Korea was the first obstacle to the Qin State's outbreak from the east. As long as it is intact, there will be no subsequent annexation of the six countries!"

"That's true!" Li Yuan nodded. The current situation was exactly the same as the pattern of the Warring States Period, and the same was true during the Chu-Han dispute.

If you occupy Guanzhong, you have a geographical advantage, only it will attack others, and it will be difficult for others to attack them!

Then, the steadily developed on the rich land within the pass will have an advantage in speed than the Central Plains, because the Central Plains are flat and lack the natural danger of mountains and rivers. The princes attack each other and have never been able to settle for production, which is behind others.

Pei Ji bowed and said, "Your Majesty, it's not time to go back. This matter should be taken seriously. I will arrange an envoy to contact the Turks, Liu Wuzhou, Dou Jiande, Xiao Liang, and Chu!"

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