Yu Ling thought about it, what the patriarch said also made sense, Datang had to arrive by ship thousands of miles away, and the logistics must be provided by Silla and Baekje.

And Datang is not Silla Baekje, their soldiers must be more demanding, how long can Silla Baekje provide Datang with supplies?

You must know that 10,000 elite soldiers, if the quality of food is good, at least tens of thousands of people need to plant land to be able to afford it.

Now the war between Silla and Baekje has consumed a lot of food, and most importantly, feeding the soldiers is more than just providing food.

The transportation of military materials requires a large number of civilians to carry out conscription, so that there is enough manpower and time to transport materials.

And the time of conscription can't be too long, but if the war drags on, then when Silla and Baekje are dragged down, the Tang Dynasty will naturally have to withdraw its troops.

"No problem, we can drag it, but Datang obviously can't afford to drag it, Silla and Baekje can't find so many people who are forced to do it, if they force it, then Silla and Baekje will collapse, and after the collapse, Datang still needs to withdraw its troops." Yu Ling said very simply.

"Yes, this is the best strategy, although I don't know what Yuangai Suwen found out about giving up this position, but Yuangai Suwen's military talent is there, since he gave up, then we can't be too careful." The Yu clan leader nodded with satisfaction.

"Yes, Patriarch, I remember." Yu Ling nodded seriously.

"It's good that you know, I know you want to prove yourself, you want to prove that you are no worse than Yuangai Suwen, but remember one thing, the more eager you are to prove something, the more you can't be in a hurry."

"Whoever achieves great things, the more cautious and anxious you are, those who are eager for quick success will undoubtedly fail, sometimes you don't care what the people next to you say, you just set your strategy to implement it." The patriarch of the Yu clan looked at him again and said seriously.

"Yes." Yu Ling nodded seriously.

"It's good if you understand, remember one thing, if you fail now, you can understand your own situation, but as long as you are not in a hurry, as long as you confront Datang, you will at least be invincible." The patriarch of the Yu clan told him from a different angle.

He is really afraid of being impulsive, because once he is impulsive, it may have very bad consequences, but as long as he is not impulsive, he will not lose.

Now that it has fallen into the stratagons of Yuangai Suwen, this is the best way.

That is, Li Ke doesn't know their tactics, if Li Ke knows, he has to say a word.

Isn't this the tactic of a certain interstellar player more than a thousand years later: as long as I don't want to win, I won't lose, flow?

But it doesn't matter, because I think so too, do you say it's a coincidence?

The result of the meeting between the two pit flow players is to see who can win more advantages.

But I'm waiting for the CD, waiting for the skills to take effect, what are you waiting for?

After receiving the position, Yu Ling quickly went to the border area, and after arriving at the border, Yu Ling began to command the army to carry out a tentative attack while deploying the army's defense.

In fact, several of the cities that Goguryeo now occupies are also Silla and Baekje, but these cities are small county towns and are not strategic points.

After releasing the scouts, it took about two days for Yu Ling to know the latest situation, Silla and Baekje almost ceded the three cities on the border, and then took the initiative to retreat.

Then a new line of defense was formed in the back, and in the most prominent city, it was the army of the Tang Dynasty that was stationed, and in addition, the two cities on the left and right sides were also garrisoned by the army of the Tang Dynasty.

After Yu Ling updated the latest frontline map, he fell silent, and these three cities just happened to be stuck in the most important strategic points of the entire defense line.

If these three cities are not uprooted, the cities on both sides will be useless even if they are captured.

Because they don't dare to go deeper, the terrain on both sides is too easy to cut off, and once cut off, it is to catch turtles in the urn.

Thinking of what his patriarch said, Yu Ling probably understood the reason, in this situation, as long as he occupied these cities that Silla and Baekje were ready to give up, and then stood still and confronted the Tang Dynasty.

That's good for him to be invincible.

Because he has a rhetoric anyway, and it's not fruitless, is it? Counting the three cities that the other party has recently given up, Goguryeo has already occupied six small cities, which can be regarded as quite a gain.

"Order, the whole army advances, and first take the three cities that the other party has abandoned." Yu Ling didn't say a word and directly issued a military order.

"Also, don't advance too fast, triple the number of scouts, and investigate everything around." Yu Ling added.

Anyway, he wasn't in a hurry.

"Yes!"

At the same time as Yu Ling's side was advancing, Li Daozong's side naturally received information about the movement of the Goguryeo border army, and his side was immediately alert, especially asking Silla to inform the people in the area of the three county towns that were about to be abandoned to prepare to evacuate.

As for whether they want to evacuate or not, it's up to them.

After all, Li Daozong is only here to "maintain regional stability" and not to "interfere in the internal affairs of other countries."

Although the Tang Dynasty has the right to interfere in the internal affairs of other countries, because the queen of Silla was canonized by Li Shimin.

But he was ordered not to interfere, so he just informed.

Whether the people can withdraw or not, that's their own business.

Silla was informed that when Yu Ling steadily advanced to the three cities, the people of the three cities had already been prepared, and the defenders retreated directly without much resistance.

The above are ready to give up, there is no point in resisting, this is also the meaning of Li Daozong.

Because their task is not to defeat or destroy the enemy completely, it is useless to resist the senseless consumption of the enemy's living forces.

Although they are all soldiers of Silla, they are also people and soldiers, and the point is that it may be the people of Datang in the future, and there is no need to consume their lives meaninglessly.

For the common people, the wealthy, nobles, officials, and soldiers of the three cities retreated.

The former was afraid of being killed by Goguryeo, while the latter had to retreat because of the military order.

As for the common people, the three counties together had nearly 100,000 people, and about 70,000 people retreated back to Goguryeo.

Of the 70,000 people, about 30,000 went to the deeper territory of Silla and went to relatives and the like, and the remaining 40,000 people were basically concentrated in the vicinity of the three cities controlled by the Tang Dynasty.

Among them, Li Daozong gathered more than 20,000 people here.

"Can our city hold the extra 20,000 men?" Li Daozong looked at Park Shinzong, an official in this county seat, and asked.

"If you go back to the general, it's no problem to accommodate them, there are enough places in the city to build temporary shacks, anyway, it's summer, and you don't have to be afraid of the cold."

"In addition, there are a lot of abandoned houses, which can also be requisitioned temporarily."
