On the grassland, the other records of the Tang Dynasty have not yet arrived, only Shi Liji, the governor of the capital of the state who was stationed in the state and sent troops at the first time, led tens of thousands of soldiers and horses into the grassland. Yi Nan's son, led the army to attack the Turkic tribes, the Hui tribe's Dadu was defeated in the first battle with the military god Li Ji, and ran for his life, Li Ji pursued at the tail, chased Dadu and did not have a chance to run back to Xue Yantuo, just wandering around the grassland, Yi Nan Khan got his son's help, and hurriedly sent an envoy to Li Ji's military account to negotiate peace.

Not to mention that Li Ji doesn't have the right to talk about peace, even if he does, he won't talk about it, and there are few people who like to talk about peace when he is a general.

Then just when Xue Yantuo's envoy didn't leave, and Yi Nan sent another envoy to the Tang Emperor to sue for peace, the Tang Emperor's order was passed to the front of the army.

It is not an armistice, but an order to launch a national war, Li Ji is the commander-in-chief of several armies, and he is also the general manager who can mobilize the most troops and horses under his jurisdiction.

This frightened the envoys of Xue Yantuo who stayed in Li Ji's army to the point that they were all dead, and they didn't pester Li Ji to negotiate peace, and hurriedly left to report back to Yinan Khan.

Li Ji didn't let the envoys be detained, anyway, this kind of thing like the national war is not something that can be done with a surprise attack, so there is no need to do anything to block the news.

And just when many generals of the Tang Dynasty received orders and rushed to the grassland to reorganize their troops, the battlefield of Goguryeo Baekje was also in full swing.

"Damn, this Anshi City really belongs to the king's eight shells, it's harder than stones." Cheng Chumo rode on his horse and watched a hundred steps away shouting to kill the siege of the city and fight the defenders, and scolded angrily.

After he and Su Dingfang converged, they easily captured Huaiyuan City, and then the two had a disagreement, and they quarreled over whether to attack Anshi City first or Liaodong City first.

Cheng Chumo is to attack Anshi City according to Wu Yuanqing's deployment, as for Liaodong City or something, it is Su Dingfang's task, and his task is to work together to defeat Anshi City, and rush to Daxing City The ultimate goal is Pyongyang.

However, Su Dingfang thought that Liaodong City should be attacked first, because Liaodong City was the first city of Goguryeo on the Liaoshui line, and the Sui Dynasty's first conquest of Goguryeo was precisely because it could not capture Liaodong City for a long time that it had a later fiasco.

Therefore, in his opinion, taking Liaodong City first is the first priority, and Anshi City is a little behind Liaodong City, if you don't take Liaodong City, you will attack Anshi City, you are likely to suffer from the enemy on your back, and you will be cut off by the defenders of Liaodong City.

The two of them have their own reasons and both stick to their own opinions. And Wu Yuanqing, the presidential marshal, is not there, the two are at the same level, and no one is convinced of the other.

In the end, seeing that a stalemate would leave too much time for the Goguryeo people to set up, Cheng Chumo retreated.

First, Wu Yuanqing asked the two of them to join forces to attack Anshi City, if Su Dingfang did not cooperate, according to Wu Yuanqing's meaning, it would not be easy to take Anshi City. Again, after all, Su Dingfang has been leading the troops for a long time, and he has much more experience and combat exploits than Cheng Chumo.

When he and Wu Yuanqing were still the leaders of the grain transportation team, Su Dingfang was already the deputy commander of the Eastern Turks who followed Wei Chigong to attack the Eastern Turks, and the most important battle when attacking the Eastern Turks was also led by Su Dingfang to lead the cavalry to raid.

Let's not talk about this, when they were still little dolls, Su Dingfang was the general of the warlord of the late Sui Dynasty who could stand side by side with Wei Chigong and Cheng Yanjin.

The qualifications were there, and Cheng Chumo felt that listening to Su Dingfang was not very unacceptable.

After much consideration, Cheng Chumo agreed to work with Su Dingfang to take Liaodong City first, and then attack Anshi City.

Then they attacked for five days, and in their opinion, Liaodong City, which should be a strong city, had been breached, and when they took the city, the two were still a little confused.

It was too easy to take, and it wasn't as difficult as the two of them thought.

When the two of them divided part of their forces to garrison Liaodong City, and then led their troops to attack Anshi City and launched an attack on the city, the two finally understood why Wu Yuanqing let the two of them take Anshi City first.

Because in terms of the solidity of the city wall, Anshi Fortress is stronger than Liaodong Fortress, the capital of Goguryeo in Liaodong.

The key thing is that because they captured Liaodong City, most of the defenders of Liaodong City were withdrawn to Anshi City, and after receiving the news of the Tang army's attack, the reinforcements transferred from Daxing City behind Anshi City had also arrived at Anshi City during their attack on Liaodong City.

In a city that is stronger and more majestic than Liaodong City, tens of thousands of defenders of the three cities are also gathered.

It's not a little bit hard.

Why did Wu Yuanqing attack Anshi City first in the first place, because he was afraid of this situation. Because they did not send a lot of troops this time, Cheng Chumo and Su Dingfang only had more than 40,000 soldiers and horses on the two routes, and more than 10,000 people led by Wei Chi Baolin attacked Pyongyang City from the water.

Twenty thousand is the sailor led by Wu Yuanqing, so don't look at the nearly eighty thousand, but after dispersing, there are not many.

Cheng Chumo, Su Dingfang's 40,000 soldiers and horses can take any single city, but if he faces a strong city, he also faces a defender far more than a city should have, it will be very troublesome.

Like Anshi City, if it weren't for the fact that the enemy was unprepared at the beginning and did not have a large number of reinforcements to defend the city and take it quickly, there would have been the situation that Cheng Chumo and they are encountering now.

They took Liaodong City first, but so what, most of the people in Liaodong City, the defenders all retreated to Anshi City, and the reinforcements from Daxing City in the rear also arrived.

It made it several times more difficult for them to attack the city at once.

If they hadn't attacked Liaodong City first, but first took Anshi City while the Goguryeo people couldn't take precautions, then Anshi City would have been a bone stuck between Liaodong City and Daxing City by the Tang Army.

It made Goguryeo extremely uncomfortable, unable to swallow and vomit.

When the time comes, if the Tang army attacks Liaodong City, or any city of Daxing City, the Goguryeo army in the other city will not be able to smoothly implement reinforcements.

Because Anshi City is a hurdle that they can't bypass, with the city to hold on, the Tang army can defend the city with a small number of troops, block the reinforcements of one side, and send a large number of troops to attack the other city.

When Wu Yuanqing made the plan, he thought it through. Mainly because he knew that when Li Shimin personally conquered Goguryeo in the original time and space, he was blocked in Anshi City.

And the Liaodong City, which blocked Emperor Yang of the Sui Dynasty, did not cause any obstruction to the Tang army at all. The reason is that Emperor Yang of Sui did not take Liaodong City that year, not because the Sui army was not good at fighting power, but because Emperor Yang of Sui gave orders indiscriminately, which led to the fact that Liaodong City was able to be captured many times, but because he had to report to him and other orders, he delayed the fighter.

Li Shimin naturally did not have this problem when he attacked Goguryeo, so it was easy to take Liaodong City.

And the 100,000 Tang Dynasty soldiers who could easily defeat Liaodong City were blocked outside Anshi City for more than two months, which shows that Anshi City is far more difficult to conquer than Liaodong City.

Wu Yuanqing's plan is very good, and if he wants to quickly take Anshi City with lightning speed, the other cities will be much easier to fight. But the plan couldn't catch up with the change, Su Dingfang and Cheng Chumo temporarily changed the target of the attack, which caused the defenders of Anshi City to double and the difficulty of conquering it greatly increased.

All the plans were in vain, and I had to attack hard.
