"So, the problem for our army at present is how to capture Rongmi City?" Yang Zhong stood on the top of the hill and looked at Rong Micheng not far away, and asked.

Jiang Xiaoyu analyzed: "As long as our army enters the valley, it will be discovered by enemy sentries, and climbing up from here to the top of the valley is not only uncovered, completely exposed to the enemy's sword, but also the steepness of this mountain is already quite difficult to climb with bare hands, let alone defense. ”

"According to what you say, our army can't take Rongmi City?" Compared with his father, Yang Zhong still lacked some calm climate, and at this moment, he was already frowning slightly, and he was a little dissatisfied.

Geng Yan persuaded: "General Yang, what Commander Jiang said is the truth, this geographical advantage has been occupied by the Donghu people, but we have people and now, the difference is the time." ”

"Oh? So there's a plan? Yang Zhong looked at Geng Yan with hope, and the latter had to explain: "The last general has not come up with a good siege plan for the time being, and the last general suggests that our army should be repaired in situ first, and as for the siege, we have to think about it in the long run." Hearing this, the passion that emerged in his eyes disappeared instantly, and Yang Zhong waved his hand, "It's up to you, let the army rest in place first!" ”

"So how are we going to take the city? If it is a direct charge, it is undoubtedly a target. Si Heng was a little melancholy in the face of the geographical advantage occupied by the Donghu people.

The sides of the canyon are unusually steep, naturally forming a barrier to Rongmi City, and there is no other way to go except the valley. An Haoran set the "main tone" for the offensive strategy.

"If this is the case, even if there is a shield and armor, it will not be able to withstand the rounds of shooting of the Donghu people, and our army marching all the way from the valley is simply giving the enemy a practice of target shooting!" Ling Feiyan said anxiously, but Si Heng was very proud because the other party agreed with his point of view and repeated it at the same time.

"Not necessarily!" Xuan Shaoning endured the inquiring eyes of several people, and finally said his inner thoughts, "Since that mountain peak is the source of the stream, and since An Duwei said that the lake has a huge amount of water, then you might as well let the lake water break away from the path of our army's advance!" ”

On the way back from Yang Zhong, Geng Yan accidentally saw a few people pointing at Rong Micheng in the distance, several of whom were regarded as his right-hand men, so he planned to join in to listen to the opinions of his subordinates, and as soon as he walked in, he heard Xuan Shaoning's idea, and immediately shouted "Okay".

"Commander Geng!"

"Captain Xuan, you just said that it is feasible to divert water to irrigate the city!" Geng Yan was worried that he couldn't think of the idea of attacking the city. "But the source of the water you are talking about is the mountain in the distance, so there are two problems, one is whether the water source is abundant and whether it can have the desired effect; Second, it is also unknown whether the mountain peak can be dug out of the gap to divert water. ”

"Whether or not these two questions can be solved is useless to discuss here, and it will be clear if you go to that mountain peak to find out." Shi Gong Zhengyuan proposed.

"Well, that's a way to do it, I'll join!" Si Heng expressed his support, but Xuan Shaoning looked at Geng Yan and was unable to express his position. Geng Yan saw Xuan Shaoning's concerns, and said: "The task of the scout is to find out the situation of the road ahead for the army, this time a few of you will serve as a scout, find out the situation and come back alive, General Yang will explain it myself." ”

With Geng Yan's approval, several people immediately eliminated their worries and turned around and began to prepare. Although Rouge begged bitterly, Xuan Shaoning still did not agree to her to go with her, but asked Xie Yi to help take care of it, and when he walked out of the camp with his teachers Gong Zhengyuan, Ling Feiyan and Si Heng, he saw An Haoran standing in front of him from a distance, and without waiting for a few people to inquire, he took the initiative to say: "I can't find anyone in this military camp who is more familiar with the terrain than me, if it weren't for my explanation, you wouldn't know that such a mountaintop lake exists, so I have to lead the way!" ”

Thirty miles southeast from the camp where the Great Liang army was stationed arrived at the mountain that had been cut off, the peak was not high, the mountain was not steep, and it was not too difficult for a few people to climb up, the only thing that bothered a few people was that the rocks under their feet were very fragile, and they often broke into a pile of earth and stones when they stepped on it, and the situation became more obvious the higher they went.

After several hours of climbing finally reached the top of the mountain, sure enough, as An Haoran said, the mountain pass is an endless blue lake, whether it is at the foot of the mountain or in the direction of the barracks, everyone will think that this is just a hill that is not high and not wide either, until standing on the top of the mountain to understand how much misunderstanding exists in the perspective of people, the blue lake in front of you is sparkling in the breeze, reflecting the ancient trees and wild flowers around, this beautiful scenery can wash people's hearts.

"If it weren't for the fact that the lake water is poisonous, I would really want to jump into the lake and have a good frolic at this moment!" Si Heng didn't care about other people's opinions in the face of a different scenery, and blurted out the thoughts in his heart, but no one would squeeze him, because this was the common idea of everyone. The deep, clear water of the lake has a kind of magic that wears down people's fighting spirit, looking at yourself in the reflection, it is inevitable to derive a kind of escapist thought, no longer trapped in the world's flies and dogs, choose a beloved to settle here, and live a leisurely life.

I said....... What are we here for! Shi Gong Zhengyuan was the first to regain his sober consciousness and reminded.

"yes...... Yes, we're here to survey this lake! Xuan Shaoning closed his eyes, shook his head vigorously, and tried to shake off the beautiful scenery that had been reflected in his mind. Along the way, I found that the rocks of this mountain are very brittle, and they can be broken into earth and stones with a light foot", after speaking, in order to confirm his inference, he once again found a huge stone by his side and placed it at his feet, and then raised his foot and stepped on it fiercely, with the flying of earth and stones, the stones instantly became slag.

"Wow!" Si Heng also tried it, and the result was the same as Xuan Shaoning's, and he still said with some disbelief: "Where is this mountain made of stones, it is a mound of earth at all, I can't believe that there is a lake in the middle of a pile of soil!" ”

"Captain Xuan, what are you going to do?" An Haoran asked.

"Since this rock is so brittle, let's dig a gap in the lake, and let the lake water rush to the city of Rongmi in the canyon." Although Xuan Shaoning hesitated, he still said his thoughts.

"That's a good idea, I agree!" Si Heng took the lead in standing on Xuan Shaoning's side.

"It's true that the rock is fragile, but if we want to dig a hole, a hole big enough for the lake to rush down, I am afraid that this thing will not be done for a while, if the movement is too big, it will inevitably not be discovered by the Donghu people, and then they are very likely to guess our intentions." Ling Scarlet Yan spoke of an obvious reality.

"That's right, if you mobilize a large army to dig up, you can't guarantee that you won't be discovered; If it's just a small number of hands, we can't afford to spend that time. An Haoran was helpless for a while.

"You can't have it both ways, but it depends on the situation!" Shi Gong Zhengyuan successfully attracted the attention of several people, "The location, the people are all here, and what is lacking now is the time!" ”

Xuan Shaoning suddenly thought of something, and his inspiration flashed but it was as difficult to catch as a meteor, "Are you talking about the weather?" ”

"That's right! Look at the barbed clouds in the distance, slowly gathering and covering the distant peaks, the sunlight can only be transmitted through the gaps between the clouds, and there will be heavy rain in 12 hours. ”

A few people stood on tiptoe and looked in the farther direction of the Red Ghost Valley, and sure enough, as Shi Gong Zhengyuan said, the gray clouds gradually began to gather, and the light transmitted from the period was full of colorful colors, like colorful feather arrows shot from the sky, which looked very magnificent in the evening.

"I remember, Senior Brother Helian once taught us!" Ling Feiyan said with some excitement, Xuan Shaoning also slowly remembered that when he was teaching Kanyuxue, Helian Ping said that he could judge the weather in the next few days by distinguishing the shape of the clouds and the angle of sunlight projection, but he didn't expect that at this moment, Shi Gong Zhengyuan would actually apply what he had learned.

"This ...... Accurately? Si Heng was still a little unconvinced.

"Isn't it 12 hours, it will be verified soon, now what we have to do is to go back to the camp to persuade General Yang and the commanders, let them agree with our plan, and send troops before the heavy rain falls!"

"Oh? Diverting water from the lake to flood the city? As soon as Yang Zhong heard An Haoran and the others' detailed description of this plan, he immediately began to calculate in his heart, he also judged the terrain of the Red Ghost Valley very clearly, it has been three days since the army reached the hills, and the reason why he did not move was that he could not find a suitable opportunity to attack the city, once the rash dispatch of troops caused the vigilance of the Donghu people, then it would be more difficult to attack next; However, if it is delayed repeatedly, the direction of the entire war will be unfavorable to the Liang, and then Emperor Liang will blame him, and it will be difficult for him to explain, and the reputation of the Yang family must not be folded in his own hands. In this show, Yang Zhong has already agreed with this plan in his heart.

"But what you said about the heavy rain sounds a bit mysterious!" Jiang Xiaoyu said: "I also think that diversion and irrigation of the city is the best siege strategy to reduce the loss of personnel, but if you want to rely on heavy rain to hide the traces of our army on the one hand, and increase the power of the lake with the help of rain on the other hand, this is completely dependent on the sky!" ”

"What Commander Jiang said is true! When he was studying at Aoyama Academy, he learned how to judge the weather based on clouds and sunlight, and it was not arbitrary. "Shi Gong Zhengyuan moved out of Qingshan Academy, and I want you to recognize your prediction of the weather for the sake of the academy.

Worried that General Yang would not trust Shi Gong Zhengyuan, Xuan Shaoning said: "The last general and Zhengyuan were originally classmates, and the last general also studied Kanyuxue, and the last general also agreed with the judgment of Shi Gong Lieutenant. Ling Scarlet Yan also stood on Xuan Shaoning's side at this moment, and Si Heng basically followed Ling Scarlet Yan.

"General, our army has been standing still for three days, I don't care about waiting for one more day, Captain Gong mentioned that it will not be 12 hours, at most tomorrow evening, the last general will believe it once!" An Haoran didn't want to see the two sides hesitate anymore, so he made a suggestion.

"That's right, just follow Captain Andu's plan, Captain Gong, and order you to lead your subordinates to dig a gap around the lake!"

"The last general obeys!"
