There are more than 22,000 soldiers in the defenders of Tongguan, including 3,000 cavalry, which is the elite strength of the defenders.

On weekdays, the Tongguan garrison is not more than 10,000 at most, but after the Turkic cavalry invaded the border, the imperial court sent a garrison in Tongguan, and Liu Zhao, the Marquis of Dingguo, also led the army to be stationed here.

At this time, a vanguard army of King Huai, without food and grass to feed, drove straight into Tongguan less than three hundred miles. This should be the Huai King to cooperate with the Min County Lord to persuade the Southern Yuan General Mu He to surrender an action, once Mu and surrender, the Huai King will garrison Tongguan, close to the capital of the Great Shun Dynasty Chang'an City.

Liu Yue didn't know much about the situation of this vanguard army, but he could guess that it should be all cavalry, and it was the elite of the Huai army, and the number should be more than 2,000 cavalry. As for why this vanguard army was able to break through the county town of the imperial court in the Central Plains and drive straight in, Liu Yu also estimated that it was related to the inaction of the local defenders.

The Huai army was so fierce that even the imperial army had to avoid its edge, and the local army could only defend and defend without the imperial order.

"From Tongguan to the southeast, to the front line, there are still sixteen county towns under the control of the imperial court, and these sixteen county towns are connected into a line, which is our first line of defense." Liu Yu pointed to the military map.

Beside Liu Yu, there were not many people, except for Xu Xuanzhu and Su Yan, only Qu Zhu was left.

Now the backbone around Liu Yu is either staying in Chang'an City to take care of the rear affairs, or he is quelling the rebellion in the southern part of Guanzhong, and there are too few people available to him. This military meeting was simple in form, but it was very important.

"Master. Can you make it clear? Su Yan was a little anxious. Because he looked at the military map, the main force of the Huai army was very close to Tongguan. And that's not even counting the mysterious vanguard army.

"Why don't you understand?" Liu Yu looked at Su Yan and asked.

"The first line of defense is these sixteen cities, but what about the second line of defense?"

"Tongguan." Liu Yu pointed to where they were.

"Also...... Is there a third line of defense? Su Yan asked again.

Liu Yu thought for a while and said, "The third way, I'm afraid it's the city wall of Chang'an City." ”

Su Yan made a difficulty, he first looked at the "first line of defense", the sixteen cities seemed to be scattered in a vast area, not in line at all, and it was probably difficult to connect them together, even if he didn't know much about military affairs. It can also be roughly understood that if the Huai army storms one place, it will inevitably take a few days to conquer a city, and it will soon eat away at this first line of defense.

And the third line of defense, Chang'an City, is his old nest, and if Chang'an City is besieged, he also feels that he can't survive. He watched it for a long time, and finally felt that the most important thing was the Tongguan they were currently in.

It is dangerous, easy to defend and difficult to attack, and it is a key pass that must be passed in the customs. It seems that there is certainty in holding Tongguan.

But Su Yan compared the size of Guanzhong and the world again, and he lost his confidence when he landed. If the Huai army really hits under Tongguan. At that time, eighty percent of the territory in the world was occupied by the Huai army, so he, the king, could only be regarded as empty.

"Master. Huai Jun ...... How many soldiers and horses are there? Su Yan mustered up the courage to ask again.

In the past, the estimate of the number of Huai troops was roughly 50,000 in the official and 200,000 in the people, but the news was not too accurate. Su Yan knows best how many soldiers he has, and if he is full of battles, he can come in handy with Tongguan, that is, more than 20,000 soldiers and horses.

Liu Yu said: "It's roughly between 150,000 and 170,000. ”

Su Yan raised his left and right hands, pinched his fingers and calculated for a long time without calculating the difference in strength between the two sides, or he didn't understand what it meant at all.

"What about us?" Su Yan's gaze became eager.

Liu Yu pointed to the first line of defense of the sixteen cities combined: "Here, there are local defenders, and there are about 30,000 soldiers in total, and there are ...... here" Liu Yu pointed to Tongguan, "20,000." ”

After the last, Liu Yu pointed to Guanzhong and said: "The last line of defense is 20,000 soldiers. Combined, it was 70,000 soldiers and horses. ”

Su Yan was originally full of sadness, but when he heard that there were 70,000, it was beyond his imagination, and he said happily: "Seventy thousand, a lot, a lot, 70,000 beats 170,000, there are still some hits." ”

Liu Yu sighed, it seemed that Su Yan still didn't understand the situation of his lonely family, and now he had to face not only the King of Huai, but also other vassal kings who had ambitions for the imperial court. Although they look like they are separated, they will still be united in the face of the great good. With the addition of the soldiers of the other vassal kings, the number of rebels will be more than 300,000.

Liu Yu said: "The comparison of forces is not compared to the head. If it is said that whoever has more heads can win, then there are tens of millions of strong men under the rule of the imperial court, and there are no more than one million strong men in Huaidi, and the court will win nine times out of ten. But the fact is that most of the elite soldiers in the imperial army are in the north, and there are about 200,000 soldiers and horses in this vein, which can be said to be the elite of the entire Dashun Dynasty. Although the strength of the Huai army is not as good as that of the border army, it is also above the strength of the local defenders, so it ...... Our certainty is still very low. ”

"Can we bring the border troops back?" Su Yan asked expectantly.

Liu Yu sighed, since the new emperor ascended the throne, the Marquis of Dingguo, as the nominal commander of the border army, has not made any other expressions except for asking the court for food and fighting against the Turks. Several times he was asked to lead the army to return, but he was also refused in the name of border military urgency. On the surface, Dingguohou is thinking about his family and country, but in fact, Dingguohou looks down on his son at all, and he also looks down on the new emperor who is closely related to his unpopular son.

"No, we're on our own." Liu Yu dispelled Su Yan's unrealistic thoughts.

Su Yan also sighed, and then asked, "Then master, how sure are we?" ”

"Shicheng, you are the lord of the world, although we are now passive, but the final victory belongs to us."

Su Yan's most trusted person was Liu Yu, and when he heard this, he finally relieved his sadness and said, "Then master, I listen to you for everything." Now what should we do first? ”

"Send a document first, and ask for a contradictory text."

Su Yan was in trouble again, he obviously didn't know how to write any essays.

Liu Yu smiled: "Don't look at me, I won't either." Call the old man, he was born in the Ministry of Rites, and he is good at doing this. ”

Yuan Bolang was still resting, and the bumps on the road also made his body unbearable, and he was woken up after sleeping for two hours, and then he was very unhappy to come to see the new emperor.

"Writing an essay?" When Yuan Bolang heard the new emperor's will, he glanced at Liu Yu first, "Your Majesty, I'm afraid it's not appropriate, and the court must come up with a suitable reason for rebellion, otherwise it will be burdened, and it will make the vassal kings disagree and join forces." ”

Liu Yu said: "Then Yuan Xiang might as well write a copy of the rebel king, and the text does not say who is the rebel king, and then send an edict to the vassal kings, so that they can assist the court to participate in the righteous act." Oh, there is no shortage on King Huai's side. ”

Yuan Bolang's most worrying thing is facing Liu Yu, this young man seems to be discussing with others everywhere, but in fact, he is the most authoritarian, not big but calculating.

"The kid surnamed Liu, since you are confident, you wrote it yourself, why do you ask the old man to do it? If you don't write well, you can't entertain the old man again? (To be continued......)
