The Tang army finally had a fierce collision with the Goguryeo army, especially under the leadership of Xue Li, the vanguard army of the Tang Dynasty pierced Goguryeo's heart like a sharp sword.

Although the vanguard led by Xue Li also encountered a lot of resistance and fought several major battles with the Goguryeo army, they all relied on thermal weapons such as gunpowder shells to achieve victory.

There is also a classic battle, when Xue Li led 5,000 Tang troops to prepare to attack a grain field of the Goguryeo army, but when they captured the grain storage site, they were surrounded by Goguryeo's army of nearly 30,000 people, and the so-called grain storage land was just a trap.

Xue Li led the Tang army to fight and retreat with the Goguryeo army, and at the same time sent people to the back to use gunpowder shells to arrange a formation similar to the mine array, and when they led the Goguryeo army to the mine array, the Goguryeo army was blown up and cried for his father.

The Goguryeo army suffered heavy losses after entering the minefield, and when they finally withdrew from the minefield, the Tang army, which had rested at this time, immediately launched a counter-charge against them.

The Goguryeo army suffered heavy losses in this battle, and Xue Li's vanguard army killed nearly 20,000 Goguryeo soldiers at the cost of more than 1,000 casualties, which greatly damaged the Goguryeo army.

And this battle also made Xue Li's vanguard army powerful Goguryeo, and since then the Goguryeo army no longer dared to face the edge of Xue Li's vanguard army, and the Tang army's conquest of Goguryeo went very smoothly.

And when Xue Li's vanguard army entered the territory of Goguryeo for more than 200 miles, most of the Tang army rushed to the border between the two countries, and at this time, the Goguryeo army was almost killed by Xue Li's vanguard army, and there was still the courage to fight against the Tang Dynasty's army.

However, the Tang side went very smoothly, but the Silla side was not so smooth, under the joint attack of Goguryeo and Baekje, the capital of Silla has been besieged, if it were not for Xue Li's vanguard army, all the way to the hinterland of Goguryeo, forcing the Goguryeo army to send troops back to help, it is difficult to say how long Silla can last.

However, no matter what happened on the Silla side, as long as everything went well on the Tang army's side, then the war would end in the victory of the Tang army.

Soon after, the Tang army and the Goguryeo army also fought the first Armageddon.

More than 50,000 Tang troops fought against 70,000 Goguryeo troops, and in the end, the Tang army defeated the Goguryeo army.

Although the overall combat effectiveness of the Tang army was stronger than that of the Goguryeo army, the superiority of various weapons and the application of thermal weapons were the key to the victory of the Tang army.

In World War I, the Tang lost less than 10,000 people, while the Goguryeo army lost 70%.

This battle also made the Goguryeo people soberly aware of the gap between themselves and the Tang Dynasty, even the army they had built up for many years of forbearance seemed so vulnerable in front of the Tang army.

Since Xue Li led a vanguard army of 6,000 people into Goguryeo, until now, the Goguryeo army has lost more than 70,000 or 80,000 casualties, but the losses of the Tang army are extremely small.

Now, the Tang army is pressing, and the Goguryeo side, except for the remaining defeated army of 30,000 people, is just a few stragglers, and they can't resist the attack of the Tang army at all.

It can be said that it is losing and retreating.

The only Goguryeo army that still had some combat effectiveness was now besieging the Silla capital with Baekje, an elite Goguryeo army of 50,000 men.

If you want to resist the Tang army, you must draw that army back, and once that army is sent back, then Baekje's army alone will not be able to capture the Silla capital, and may even be counterattacked by the Silla army.

But compared to taking Silla, the capital of Goguryeo is obviously more important, not to mention, the vanguard army of the Tang Army of Xue Li has now been killed, and I am afraid that it will be able to kill their capital in a few days.

In view of the prestige of that vanguard army, I am afraid that it is impossible to defeat them without a regular army of 20,000 or 30,000, and now most of the Goguryeo army is in front to resist the main force of the Tang army, and the regular army left in the national capital is no more than 10,000 people.

They can only hold on, hold on and wait for help, but where are their reinforcements?

The only way to get the elite army that attacked Silla was to come back to their aid, and that was their only lifeline.

Only when the elite army comes back can they solve their current urgent needs and relieve the current siege of the national capital, and only by relieving the siege of the national capital can they free up their hands to support the main force on the front line, so that they will not be immediately defeated by the Tang army.

In the face of such a war situation, the king of Goguryeo could not have imagined how the hundreds of thousands of Goguryeo troops could be so vulnerable in the face of the 60,000 Tang Army's Eastern Expeditionary Army.

Unlike the sorrowful Goguryeo people, the Tang army continued to send good news, and the people of the Tang Dynasty were jubilant, especially when the good news came to Chang'an one after another, Chang'an City was even more jubilant.

If Goguryeo can be subdued, then all the surrounding countries that are slightly stronger will be defeated by Datang, and Datang will naturally become today's hegemon.

In many cases, if the country wants to achieve tranquility, it must adopt the means of war, subdue others, and whoever sees you will have to tremble a few times, so that naturally they will not be bullied by others.

Moreover, not long after the founding of the People's Republic of China, Datang has already subdued the surrounding countries, so for many years to come, Datang will not have to worry about being harassed by them.

According to the current development of Datang, it is now the beginning of a prosperous era, as long as they can maintain their current attitude, then Datang will only get stronger and stronger, and the lives of the people will get better and better.

Everything will get better and better.

Whether it is the people, the minister, or Li Er, they are all very happy to think of such a result.

Zhang Yi only occasionally inquired about the battle ahead during this time, basically, the news he knew, as long as the people in the market inquired a little, they would also know.

He didn't pay much attention, if it weren't for the fact that he recommended Xue Li, and now he had to see how his record was, Zhang Yi wouldn't have paid attention to these things at all.

Now he travels all day long, accompanied by beautiful women, and all the operations in Zhangjiazhuang have been running normally, and he doesn't need to care about anything at all.

On such a day, he is chic and free, like an idle cloud and a wild crane, how comfortable, and he still wants to take care of those worldly things.
