As the former chief General of Yangcheng in Xi'an, we can say that he knew the situation of Yangcheng in Xi'an like the palm of his hand. After leaving the Chinese Army's tent, Tang Shi immediately took Gao Lan and went back to camp together.

"Old Tang, is there any good way? We have set up a military order in front of the general. If we can't attack tomorrow, we will lose face and lose our hair. " Gao Lan didn't care about anything else. When there were no other generals around, he took the Tang style and asked repeatedly.

"don't worry, generals. If we don't dare to say anything about other cities, this xi'anyang was built by us, and all the things are printed here." Tang style one face solemnly said, said, also pointed to own head with the finger.

Looking at the Tang style, Gao Lan was a little relieved. Although he had been to Xi'an for several times, it was definitely not worth mentioning compared with the Tang style. Now seeing the Tang style's promise, he finally settled down.

After looking around, he motioned to their soldiers to pull the distance apart. Gao Lan asked carefully, "come on, what's the best way? If you don't say it, I always feel that there's no bottom. "

"Hehe, the general may not know!" Tang Shi laughed and said: "when we first arrived in Xi'an Yang City, although we soon captured the city, we strengthened the city defense in order to prevent the troops from fighting back. However, because we were in a hurry, there was a section of the city wall in the southwest corner of Xi'an Yang City, which was not solid. We just strengthened the old city wall."

Speaking of this, after a pause, he added: "later, although Xi'an Yang was reinforced again, that section of the city wall was not demolished and rebuilt, but was wrapped with another layer of wall bricks, because the length of that section of the city wall was not too long. If someone else came to attack the city, it might be difficult to find this flaw, but for the future, it could be said that it was a hand to catch It's a matter of time

Gao Lan was overjoyed, patted Tang style on the shoulder and said, "OK, great. If that's the case, you'll be the first one in this battle."

"Don't worry, general. Since we are colleagues now, we should take care of each other. However, if we want to capture the city one day tomorrow, we need to prepare a large number of catapults, so... " Tang style road;

"don't worry, the craftsmen of the Tang army are first-class in the whole world. Today's catapult has been made and can be disassembled at any time. Now it only needs the craftsmen of the barracks to install it. Go to the rear camp, and you can talk about the situation of the city wall, and how many catapults and stone bombs do you need?"

……

Gao Lan and FA Zheng's actions soon spread to Tian Yu and FA Zheng. They looked at each other with a smile and did not speak. Instead, they put their eyes into the intelligence before their respective cases. The cases in front of them were already filled with domestic intelligence from Fushi, which was specially ordered by Huangfu Chaobo to be sent from Fushi.

……

On the top of Xi'an City, Zhao general Zeng Sheng led more than 100 bodyguards to stand on the top of the city. Looking to the West several miles away, what he saw was a tent ten miles away, where the Tang army had camped. Looking at the continuous barracks, the general couldn't help taking a breath.

He was originally a captain of the Zhao army. Although he was not the most capable in Zhang Liao's army, his victory was in being calm. So this time, he was selected by Zhang Liao from the army and appointed as the garrison general of Xi'an city. Of course, his official position was also promoted to two levels, from the original one thousand captains to Zhonglang generals.

Like him, there are more than ten generals in each city. According to Zhang Liao's arrangement, the least of them are 3000 soldiers and the most of them are 5000 or 6000. For example, there are 6000 troops in Yangcheng of Xi'an, which has become the largest number among Shuofang and Wuyuan counties, next only to Guangmu City guarded by Zhang Liao himself and the army stationed by Song Xian in Fuyang It's a city.

Zeng Sheng knows that at the beginning, general Zhang Liao once said that he didn't need to lead a dead battle by himself. He only needed to stick to it for about half a year. At the beginning, everyone thought that it would be OK to keep it for half a year. Now when he saw the army outside the city, Zeng Sheng knew that he took it for granted.

Although his heart was full of ups and downs, he was an old soldier after all. Zeng Sheng's face did not show half of his timidity. Looking at the Tang army camp outside the city, he opened his mouth and said to the nearby soldiers: "pass the orders, double the patrol tonight, and all the soldiers are ready to fight."

"Yes, general!" With a promise, the soldier turned and went to the other gates.

……

In the back camp of the Tang army camp, the lights were bright and did not go out all night. With the help of thousands of people, hundreds of craftsmen assembled the catapults overnight. At twilight, 50 medium-sized catapults were finally assembled according to the requirements of the Tang Dynasty. After the Tang army used the Korean food, 30000 troops left the camp and rushed towards the direction of Xi'an Yang.

Three hundred paces away from the western wall of Yangcheng in Xi'an, Gao Lan directed ten thousand troops to the north and south of the city, and the main attack in the West was given to five thousand troops led by the Tang style. As for the 15000 troops under Xu Huang's command, they were escorted around the catapults to ensure their safety.Under the command of the Tang Dynasty, fifty catapults came to the southwest of the city wall, stopped 200 steps away from the city wall, and formed three rows from 200 steps to 250 steps, ready to attack the city wall more than 200 steps away. The attack distance of medium-sized catapults is just 200-250 steps, and the Tang style arrangement allows these catapults to cover the whole city wall within the attack range.

When the catapult was in place, the north and South armies also sent the signal that the troops had been in place. When Tang Shi looked up at Tian Yu, who was in the middle of the army, he saw a red flag waving towards the city wall, which was a signal to attack the city.

Seeing this, Tang Shi immediately looked at the commander of the catapult beside him and ordered: "pass the order down, and the catapult will aim at the southwest corner of the city wall and test fire 50 steps North!"

"No!" After hearing this, the young general quickly took orders, turned around and ordered the taxi driver to operate the catapult: "aim at the city wall for test firing!"

"Launch!"

"Whoosh..."

"Boom..."

A stone bullet flew out in the direction that it had been aimed at, and soon fell in the direction of the city wall. Unfortunately, this stone bullet did not hit the city wall, but fell a few steps in front of the city wall. Immediately, the taxi driver who was in charge of observing the falling point of the stone bullet sent the news. After careful comparison, the primary school ordered the cable of the catapult to be adjusted, and then the second round of test firing was carried out.

So back and forth, until the fifth round, the first stone bullet accurately fell on the city wall, splashed countless stones on the head of the city, and injured several Zhao soldiers who were responsible for the observation. For a moment, the city wall rang out a tragic cry for help.

When Tang Shi saw this, he cheered for a moment. Tang Shi even yelled: "go on, go on, all the catapults will attack, and they will smash the catapults to the position just now. In the first round, get ready to attack, wait for the catapult to stop attacking, and then follow the general to attack! "
