After the arrangement was completed, Gao Yue, under the command of the guards of the Collision Lang Army, carried the battle flag of Advocate and Pixiu, and advanced to Tianzhong Mountain, which was only three miles north of Runan City, to wait for the situation in the city.

Tianzhong Mountain, the bottom of the mountain is a stone, and above it is a soil forest, and there is a Jing River flowing out in it, which is poured into the moat under the north embankment of Runan City.

When Gao Yue's banner appeared on the Tianzhong Mountain, all the Cai soldiers in the city were shaken, and Wu Shaoyang, surrounded by a group of generals, also ascended to the sub-city in the northeast corner of the city, and almost faced Gao Yue.

However, due to the distance of several miles, there is no possibility that the two will talk before the battle.

On the other hand, on both sides of the Jing River between Tianshan Mountain and the north and south embankments of Rubei, the battle between the outpost troops of the official army and Cai Bing was extremely fierce.

Gao Yue can overlook that there are about 1,000 Cai soldiers on the opposite side, building a wooden barricade on the north embankment of the north of the city, and then constructing two wooden bars in the front and back of the goose and duck lake in the east, and surround the double earthen embankment and wooden fence as protection, and shoot bows and crossbows from the inside, which is as urgent as rain.

And a hundred steps away from the opposite side, the two generals of their own Dingwu army are also very brave, pushing all kinds of vehicles in front, digging earth is also surrounded by long walls, small flags are shaking, the white smoke of the guns is dotted, the sound of guns resounded for several miles, under the cover of gunsmoke, Gao Yue saw several teams of lightly armed bombardiers, holding shields woven with bamboo and reeds, approached the embankment in the north of the city, and kept throwing iron bombs up, but the embankment was too high, four feet long, and the iron bombs could not be thrown into the camp of Cai thieves at all. Halfway up his waist, he kept rolling down, and bursts of flames and smoke rose in Gao Yue's eyes.

Soon after, the Dingwu army's infiltration attack on the embankment north of the city failed: the bombardiers dragged their wounded and dead companions out of the smoke and retreated behind their own earthen embankment.

However, the north embankment and the Huaixi camp are still majestic.

Cai Fengyuan and Guo Zaizhen came to the top of Tianshan Mountain, and Gao Yue pointed to Runan City and asked them what the deployment of the siege was, and what difficulties there were.

The two frankly said that this Runan is also called the Hanging Gourd City, and the terrain is too easy to defend and difficult to attack: there are moats and lakes on all sides of the city foundation, and there are embankments and earthen ramparts outside, and then there are rivers such as Rushui outside, and the whole city is higher than the rivers and lakes on all sides, which means that it is difficult for our foot soldiers to cross over, and it is also very difficult for siege equipment to hit the city wall from the bottom up.

Therefore, the temporary deployment is to concentrate on the elite of the Dingwu Army and the Yining Army, and then cooperate with the strategy of Yu Di's army stationed in the Lianshui Department, preparing to first capture the west city of Runan, and then the east city, and finally capture the sub-city and capture Wu Shaoyang.

Gao Yue bowed his head, and also sighed and said:

"Since the terrain of the Hanging Fortress is higher than the rivers on all sides, the tactics of building a weir and attacking the water are not feasible at all."

"Not feasible." Cai Fengyuan and Guo Zaizhen also echoed Gao Yue.

So Gao Yue continued to carefully observe the surroundings of Runan City for a long time, and it was not until evening that he descended from Tianzhong Mountain.

Back behind the tent, military intelligence from all walks of life also converged.

It's all frustrated news.

Yu Di was stationed in Yichun and commanded his army to launch an attack on the west of Runan City, but was blocked at the Duanji River: similarly, Cai's soldiers also built a fence in the high ground on the other side of the river, and Yu Di's soldiers and horses were blocked by a dense number of arrows when they waded into the water, and they were quite killed and wounded, and they retreated in defeat.

If the mouth of the Duanji River is not obtained, Yu Di will not be able to connect with the battle lines of the Dingwu and Yining armies, and it will naturally be impossible to talk about the capture of Runan Xicheng.

In the north of the city, the triangle lake and the Shijia Lake, Shence, Shenwei and Xuanwu troops also fought with Cai soldiers today: three hundred Cai soldiers rode mules, suddenly opened the gate and killed, attacked the army of the official army to transport grain, took away many husbands, Liu Chang and Wang Pei led the cavalry to kill, the two sides fought a melee, and then Cai soldiers retreated along the middle of the two lakes, Liu Chang bravely chased in, because the terrain was too narrow, other Cai soldiers cut off the way back by small boats, and also lost some soldiers and horses, and the two sides each boycotted and returned to the camp.

As for the south of the city, Cai Bing also relied on the camps and embankments of Nanhu, Chaitan, and West Lake to repel many attacks by the official army.

In the east of the city, Cai Bing simply dug up Hongchipi, allowing the water to overflow for dozens of miles, and everywhere he passed turned into swamps and mud: Xu Sibu from this side, that is, the independent mule battalion of Dingwu, was blocked by the water, and could only sigh with admiration.

Under the candlelight, Gao Yue looked at the topographical map of Runan City, thinking about the battle on all sides, and constantly deducing the siege plan in his heart.

In the end, he didn't make any substantial progress, so he took a long breath and summoned a few heralds, "Since the eastern part of the city is completely submerged by Hongchipi, then let Xu Si, Su Pu, and Li Yu, the troops and horses, go around to the south of the city and join Yan Zhen's Wuchang army and Li Xian and Zhou Ziping's troops. ”

The next day, Du Huangshang came and told him the news with a heavy face:

Many ministers thought that since Wu Shaocheng was dead, and Huaixi was willing to hand over Shenzhou and Guangzhou, it would be equivalent to complete surrender, and the court would have to leave a way for the other party to regain themselves, and the treasury was now spending military expenses, and the war was over, so why force it to complete the battle?

"Ridiculous!" Gao Yue was furious.

"There are even people in the DPRK and China"

"It doesn't hurt to be obedient."

"Someone in Yushitai was impeached, saying that if you continue to fight Yisong, I am afraid that you will repeat the mistakes of Zhuge Ke back then."

"Who?"

"Serve the Emperor Smuzan."

Gao Yue snorted coldly and asked the emperor what he said.

"The Holy Lord has a firm attitude, saying that even if he dumps all the big Yingqionglin immediately, he will support us to go on the conquest, but the Holy Lord also said that the deadline is May, and if Runan City cannot be captured in May, then it will be passive." Du Huangshang said.

This time the emperor was very firm, after all, there was a radish of "Feng Zen Taishan" urging this man to never give up.

But the emperor's limit is also in April and May, and there are only three months left to be full.

If I really fall short in Runan City, my expedition will not be perfect at all, and I am afraid that my right to speak after returning to the dynasty will also be attacked.

Du Huangshang stepped forward at this moment, looked at the map on the table, and suggested: Why don't we also build a five-zhang high earth mountain, and then transport the big bronze cannon to attack the city, and shoot the city wall of Runan from Yuanping?

"In this way, even if we are lucky enough to shoot down a section of the city wall, but the infantry is still blocked by the high embankment and lake, and the equipment can't be accompanied, then Wu Shaoyang asks the defenders to repair it at any time, and we still can't open the gap and occupy the city." Gao Yue said that Du Huangsheng's plan had been considered before, but it was not feasible.

Du Huangshang asked what should be done.

Gao Yue said Zunsu, the current situation requires you and me to calm down, and when Yi Shen and Wang Yi's flyships come, the battle situation may take a turn.

Du Huangshang nodded in agreement.

As a result, the next night, a group of heralds entered the tent in a rage and told Gao Yue a terrifying news:

"Ji Gong, Liu Yihuai, the soldier and horse envoy of the Xuanwu Army, suddenly pulled out the camp and retreated at dusk, leaving a big gap in the formation in the northeast of Runan City!"

"Bastard! Is this an official soldier of the imperial court, or a thief like Cai Thief? Gao Yue slapped the case, and his chest was full of anger.
