His Royal Highness the Crown Prince: "If there is any way to crack it, Shikang, you can quickly tell me and listen to it." ”

Lu Shikang took another sip of tea and said, "We can make a plan and make the other party think that we have not seen through their conspiracy." ”

As he spoke, he put the teacup on the table and continued: "After talking with the old man that day, I walked around the lake with the Tangbao cavalry, and found that there were no fish in the other streams except for the stream next to the old man's mountain residence, so we can have the troops stationed at the foot of Lishan, but the water can only be drawn from the streams on other mountains, not from the lake below the mountain, after all, the water flows down, and the water above the other streams will not be polluted by the horse manure where the old man lives. ”

His Royal Highness the Crown Prince nodded and said, "This is indeed a solution. So, what about the other dangers of that route? ”

There are dangers everywhere, so I only mentioned one place, and as for whether to go to Hanshan from that route, it depends on the other three dangers.

Lu Shikang said: "The second danger is the Zhushan Mountain, which is about fifty miles east of Lishan. ”

His Royal Highness the Crown Prince took a sip of tea and said, "What's the danger here?" ”

Lu Shikang said: "Although the mountain is not a high mountain, there is no steep and dangerous slope, most of the mountains are relatively gentle, but there is a section of the mountain road is a loose rocky place, many slopes are full of gravel. Most of these gravels are formed by the deep age of the rocks, the wind and rain or the decomposition of the tree roots, and the residents around the mountain came up with a soil method to surround the loose gravel with a huge hemp rope net in order not to be hit by the gravel when passing by this section of the road. The hemp rope goes down to the foot of the mountain and goes up to the halfway point of the mountain. Further up, due to the slower slope of the summit, the gravel generally only falls to the upper end of the hemp rope net, and is stopped by the hemp rope net, so there is no hemp rope net above.

If the enemy sends a few dead men to ambush on the hillside and cut the upper end of the hemp rope net while our army is passing by, the loose gravel that has been surrounded for many years will immediately roll down the hillside, and our side will surely suffer heavy losses, and if we are unlucky, we may even be completely annihilated. After all, there's no path to go around here. ”

"How long is that hillside?" His Royal Highness the Crown Prince asked.

"Two miles away."

His Royal Highness the Crown Prince frowned and said, "So, even if our side sent people to patrol there earlier, so that the enemy soldiers could not get close to that section of the road, wouldn't it be possible?" ”

Lu Shikang said: "There are so many mountains in the area of Huanshan that we can't know which mountain range the enemy enters the slopes here, and we can't miss any enemy soldier, as long as we miss one, he can easily cut the hemp rope, so that our side suffers heavy losses." ”

"So, what do you mean?" His Royal Highness the Crown Prince looked at Lu Shikang, "You can only take the other two routes?" ”

"You don't have to go the other two routes. It's just that we need to be prepared to climb the mountain on this part of the road, and there is no danger when we walk up the mountain. The enemy would have thought that we would go down the hill and lay in ambush on the hillside, but they would not have imagined that we would have a smooth path down the hill and would take the hillside full of thorns and jungles. However, this makes the journey two to three times longer. ”

"It's okay to delay a lot of time, safety is the number one priority." His Royal Highness the Crown Prince said.

"Of course, we can also assume that the enemy did not notice this journey, nor did he think of this method, which caused us heavy losses, and passed through this section of the road quickly. It's just a bit risky. ”

His Royal Highness the Crown Prince said: "On the march to war, we must assume that the enemy sees all the dangers we may face, and we cannot assume that they are ignorant of our dangers. Only by being cautious can we make a 10,000-year-old ship. ”

Lu Shikang said: "What His Royal Highness the Crown Prince said is very true, the other side suffered heavy losses in the last battle, and now that he has retreated to Hanshan, he must have already investigated all our possible marching routes and set up many obstacles on the road. ”

"So, where is the next danger?"

"The next dangerous place is the flat road when we are about to reach Shanglu City, which belongs to the town of Hawthorn, a stone town, and I have observed that there is no open space without trees within a radius of fifty or sixty miles for us to set up camp, that is to say, we will inevitably need to camp in the woods."

"It's always risky to set up camp in the woods."

"Yes. If the enemy sets fire to us overnight, we will surely suffer heavy losses. ”

His Royal Highness the Crown Prince said: "Well, when their forces are weak, they will inevitably think of arson. So, what do you recommend? ”

Lu Shikang said: "At the place where we set up camp, dig a fire ditch about two zhang wide, and send people to guard the ravine day and night, so that the enemy cannot get close to the woods where we stay overnight and set fire." ”

"Dig a two-foot fire ditch? It's quite a project. His Royal Highness the Crown Prince said.

More than 100,000 people are encamped, and the range of woods where they sleep at night must be not small, so the circle of fire ditches dug must also be large.

"This is the only way to ensure that you get to the other side's barracks without any mistakes." Lu Shikang said.

"Brother Wei just sighed, don't he has no intention, since the fire ditch must be dug, then only the labor division will move the people. Fortunately, there are more than 100,000 soldiers on our side, and many of them work quickly. His Royal Highness the Crown Prince said.

"There is one last danger, which is a large river that is about to approach the Cold Mountain, this river is called the Xiao River, and it is located twenty miles west of the Cold Mountain." Lu Shikang said.

"What's the danger of this river?" His Royal Highness the Crown Prince asked.

"This river is the only way to the cold mountain, the river is a hundred zhang wide, the river stretches for hundreds of miles, but there are very few bridges on the river, if you want to bypass this river, you need to travel almost sixty miles."

"At that time, when the Tangbao cavalry first reported to me, they used to say that there was a bridge on this side that could lead to that side."

"If the other side destroys the bridge while we are crossing, then we will be in danger of falling into the river, and because of the rapidity of the river, many people may be swept away by the current. Even if many of the soldiers knew how to swim to the other side of the river, but it was the month of November, and many of them might be suffering from typhoid fever because their clothes were soaked in such a season, and because the enemy occupied an easy and difficult place to attack, we would not be easily attacked by them, so that a large number of soldiers at close range of the enemy were afflicted with typhoid fever, giving the enemy the opportunity to defeat us easily. ”

His Royal Highness the Crown Prince said: "Just as we defeated them a few days ago when they were suffering from typhoid fever. ”

Lu Shikang said: "Yes." ”

"So, is there a way to crack this?" His Royal Highness the Crown Prince asked.

"Yes." Lu Shikang said.

"What's the solution, detour?"

"There is no need to detour, I have seen it for my brother, there are many bamboo ...... on this side of the river"

His Royal Highness the Crown Prince didn't wait for Lu Shikang to finish speaking, and said with a smile: "Then we can cut down the bamboo and build a bamboo bridge in the river." ”

Lu Shikang said with a smile: "His Royal Highness the Crown Prince and Brother Wei want to go together. ”

His Royal Highness the Crown Prince said: "I didn't expect you to make so many discoveries in this industry. If we do not re-explore the road, we will inevitably face a crisis. Therefore, the previous Tangbao cavalry was suspected of dereliction of duty......"

Lu Shikang hurriedly said: "It's not that they are derelict in their duties, they just don't assume that the enemy will set up obstacles on the road, so along the way it is more to see if the terrain can be set up in camp, and for the younger brother to assume that the enemy will set up obstacles on the road, so along the way it is more to see where the enemy is easy to set up obstacles." If the enemy does not set up obstacles, it may be useless for my brother to investigate. ”

"For the sake of brotherhood, we must assume that the enemy also sees the danger we face, so as to avoid falling into his trap. Only by being careful every step can you reach Hanshan smoothly. If we turn a blind eye to the dangers we may face, what is the difference between walking blindly? ”
