The 20,000 Tang troops were divided into three parts, and three sharp knives were inserted straight into the Goguryeo king's body, just a few centimeters away from his heart.

It seems that as long as the Tang army exerts a little force, it will pierce the heart and give Goguryeo a fatal blow!

Before this, Goguryeo's attitude towards the Tang Dynasty had always been unfriendly, perhaps because it had never fought with the Tang army, perhaps because it was too far away from Chang'an, and there was no so-called awe for Li Shimin, or perhaps it was from the Central Plains to attack Goguryeo again and again without success, so Goguryeo went down to the people and peddlers, and up to the princes and ministers all mistakenly thought that the Tang people were not Erer.

Everyone carries a head on one shoulder, and there is nothing to be afraid of.

However, after the Tang army showed their perverted combat effectiveness some time ago, Goguryeo gradually put away their conceit and still faced their opponents.

After careful study, I found that this behemoth, which is more than I don't know how many times the land area is, is also ...... in strength I don't know how many times more than I know.

If there is a real fight, he should burn incense and worship the Buddha if he is not destroyed, let alone maintain the current land.

No, as soon as the Tang army moved, the king of Goguryeo was frightened and convened his ministers to discuss how to deal with the Tang army.

After discussing for a day and a night, there was not necessarily a good way, which was nothing more than to stop the fighting between the south and Silla, gather troops, and mainly deploy troops in the north to resist the main force of the Tang army.

At a time like this, it is definitely not the time to be arrogant, and what should be restrained must be restrained.

So there was almost no opposition, and the first order was to stop the battle with Silla in the south, withdraw half of the army from the south, transfer it back to the north, make fortifications, and be ready to respond to the attack of the Don army at any time.

As for the Silla lands occupied in the south .... There were only three small cities in total, and Goguryeo chose to give up directly, and all the troops withdrew from Silla's territory.

Compared with these three small cities, their own land was more important, and the Goguryeo monarchs and ministers still recognized this very clearly, so they very simply and decisively gave up the cities occupied in Silla.

After the Goguryeo army retreated, the Silla army, which reacted, immediately pursued the victory, and regained the lost territory all the way unimpeded, just as they pursued to the original border between the two countries and planned to get closer, but they were subjected to a desperate counterattack by the Goguryeo army, and an earth-shattering battle broke out.

In this border offensive and defensive battle, Goguryeo and Silla invested a total of 30,000 soldiers and horses, fought for three days and three nights, and more than ten large and small battles broke out.

Although the number of people is not large, the battle is very fierce, I don't know how many soldiers fell, but I remember that after the war, I looked at the corpses everywhere.

The battle was inconclusive, and both sides ended in an armistice because of heavy losses.

In the casualty statistics after the war, there were 30,000 troops, and the total number of soldiers who fought in the end was less than 8,000, and the rest were either dead or seriously injured, which shows the tragedy of this battle.

In any case, after this tragic battle, Silla in the south would no longer offend the north, and Goguryeo also redeployed its forces, and there was an eerie period of calm on its side.

But calm on the surface does not mean calm in private.

The Goguryeo monarchs and ministers constantly sought a solution to the matter, and they sent wave after wave of envoys to the camp of the Tang army in an attempt to negotiate.

It is a pity that none of the high-ranking generals of the Tang Army did not see the Goguryeo envoys, and the illusion of negotiation ... Burst.

But Goguryeo did not give up and couldn't get the generals of the Tang army, so in another way, they sent envoys thousands of miles away to Tang, bringing light tribute and peace letters, intending to persuade Li Shimin to let Li Shimin withdraw from the army.

On the other hand, Silla also stepped up its efforts to send envoys, on the one hand, they stepped up their contact with the Tang Dynasty, constantly courted Li Shimin, and bowed down to Chen Chen, on the other hand, they also continued to find ways to transport some materials to the Tang army, intending to establish a good relationship with the Tang army.

Even Belle, who had planned to watch a good show, couldn't sit still, followed the example of the two countries, and sent envoys to show goodwill to the Tang king.

Originally, the situation of the three kingdoms on the Korean Peninsula was extremely unbalanced because of the Tang Dynasty's sideways, and the current situation is not to fight whose soldiers are strong, nor whose grain and grass reserves are sufficient, but to fight who has a good relationship with the Tang Dynasty.

Whoever Datang helps, who takes the initiative, so everyone focuses on Chang'an, which is thousands of miles away.

What about Chang'an? Chang'an has been very busy recently, and the envoys from Silla and other places are still on the way, but they have to coordinate the entire battle situation.

Grain has already begun to be requisitioned, and some necessary military supplies have begun to be sent to the north.

Even the artillery began to move slowly to the north, and it was clear that Li Shimin was absolutely unwilling to scare and scare Goguryeo, and sooner or later the war would really start, it was nothing more than a matter of time.

Of course, out of fear of the power of cannons and thunderbolts, and fearing that such items would be intercepted halfway, Li Shimin also took precautions, and the cannons were transported to the north, but the shells and thunderbolts were not delivered, and they would not be taken out of the warehouse until the real war started.

Strategic materials were constantly sent to the north to prepare, and the ministers were very busy, and even Chen Fei, who had always been stealing chickens and dogs, was also arranged to work on the "front line".

What to work for? Farming!

Yes, that's right, Chen Fei, a person who has never touched a hoe much, is now standing on a fertile field and teaching a group of old farmers the knowledge of farming.

The new species urgently needs to be promoted, and Li Shimin also sees the benefits of the new species and is eager to promote it to the whole country, so that the people can have a full stomach.

So Chen Fei was taken out, and it was rare that he did not lock him up in the strange workshop to make a thunderbolt fire, but asked him to explain to these old farmers how to plant new species before the day of spring sowing was coming.

It doesn't matter if you don't talk about it, Chen Fei can't stop talking about it, he not only explained how to plant new species, but even popularized how to increase crop yields to farmers.

For example, artificial pollination, such as hybrid rice.

Although the theories involved were very profound, Chen Fei explained the principles to them in a very vulgar and superficial way.

"The grain is the same as the big guy making a baby and giving birth to a child, there must be a step, everyone understands, I won't go into details, and these crops, everyone knows, they are dead things, they can't be moved, so what to do? It's the bees that do it for them. Bees will have pollen on their bodies, and pollen transfer can be understood as... Well, you just know, don't be evil, and don't laugh! It's a very sacred thing. In short, if there are fewer bees and no pollinator, then it is up to us to help the crops ........"

"What!" The peasants cheered, followed by laughter.

"Yes!" Chen Fei smiled with relief. Well, the comprehension ability is very good, they are all manufacturable materials!
