Xiao Ding looked at the eager eyes of the generals, cleared his throat, and said unhurriedly: "Today before the battle, I carefully observed the terrain of Luoshui Pass. Luoshui Pass was built right on the mountain pass of Jianyu Ridge, and the mountain pass was firmly blocked. With the Hu army guarding, it is difficult for our army to fly through this pass even if it has wings. ”

Speaking of this, Xiao Ding paused, glanced at everyone, and continued: "Although the Luoshui Pass Wall is high and dangerous, easy to defend and difficult to attack, it also has its geographical flaws. I think everyone has also seen it, Luoshui Pass is east and west, its north and south sides are the cliffs of Jianyu Ridge, the city is stuck under the cliffs on both sides, if we climb to the top of the cliffs on both sides, condescendingly, put arrows into the city, or throw some rolling wood and stones, etc., the Hu army in the Guannei will inevitably be in chaos, and our army will take the opportunity to tackle the key problems, and it will definitely be able to break through the pass in one fell swoop! ”

"Tian Dutong, it's easy for you to say, do you know that the cliff of Jianyu Ridge is extremely steep, and now the mountain is covered with snow, where do you say that you can climb it if you climb it?" Rothmao retorted loudly and relentlessly.

Gao Wanjun and Huang Wenlong also thought of the question that Luo Simao thought of, and they also locked their eyes on Xiao Ding's face, waiting for his answer.

"I've thought about it, but I don't think it's a problem, it's obviously much easier to climb a mountain than to tackle it. When I was observing the terrain of Luoshuiguan today, I also took a closer look, and I saw that the cliff on the side of the Luoshui River was relatively gentle, and we could choose to climb the mountain from there, and choose a few people with strong bodies to climb up first, and then put down the rope, and the people below could pull the rope up the mountain. Xiao Ding explained slowly.

"If you can really climb to the top of the cliff, it will be a clever plan!" Huang Wenlong nodded and said.

"Then that's it, Ding Dutong, you go to the camp tonight to select five hundred soldiers who are good at mountain climbing, lead them to climb the Jianyu Ridge first, and then lower the rope, and we will send people up to support later." Gao Wanjun instructed Xiao Ding, and it was obvious that she also agreed with Xiao Ding's plan.

That night, Xiao Ding selected 500 soldiers from the camp who were sturdy and good at climbing, brought necessary tools and items such as ropes, and quietly left the camp and came to the bottom of the Jianyuling cliff.

The Jianyu Mountains run north-south, stretching for thousands of miles. The cliffs are high, the cliffs are steep, and the mountains are covered with snow, making it difficult to climb them.

Luoshui Pass is just blocked at the gap of Jianyu Ridge, and the north and south sides of Guancheng are mountain cliffs, which are much higher than Guancheng.

Xiao Ding led people to stand in front of the mountain, and with the help of the moonlight and snowlight, he carefully observed the cliffs on the north and south sides of Luoshui Pass, and found that the cliffs on the side of the Luoshui River would be slightly gentler in some places, and it seemed that it was relatively easy to climb. The cliff on the south side of Luoshui Pass is much more dangerous, and it is estimated that it will take more effort to climb it, and it will also be more dangerous.

The source of the Luoshui River comes from the mountain stream on the Jianyu Ridge, because of the large flow, there is no ice in winter.

Xiao Ding led 500 soldiers to the relatively gentle position of the cliff not far from the Luoshui River, checked the shape of the mountain, and found that even if it was relatively gentle here, it was not easy to climb up.

Among the 500 soldiers, some of them volunteered to try to climb first, but unfortunately several of them, after many attempts, they did not climb far, and they all stumbled and slipped down.

Seeing this, Xiao Ding was worried that the soldiers would be damaged, so he hurriedly stopped the soldiers from trying again. I thought to myself, I still have to go into battle myself.

Xiao Ding knew that after all, he had practiced the "Melting Heart Technique", and after reaching the first layer, not only did his strength and speed increase significantly, but his sense of sight and hearing was also beyond ordinary people, and he even felt that his memory was also getting stronger. Moreover, when he went to Luoxia Mountain before, he had also climbed the cliff with his bare hands, and he was confident that he was more experienced than these soldiers in climbing the cliff.

However, the ideal is plump, and the reality is skinny. When Xiao Ding climbed by himself, he was also not much stronger than the other soldiers, and when he climbed about three zhang high, his feet suddenly slipped, and his body immediately slid down the cliff.

The height of more than three zhang is equivalent to more than ten meters high in later generations, and if you slip to the ground, even if you can't die, you have to fall and be seriously injured.

At the critical moment, Xiao Ding quickly pulled out the dagger on his waist and quickly inserted it into the stone crack of the cliff wall, and his body was instantly hung in the air. This dagger was obtained by Xiao Ding when he went to Luoxia Mountain, and it was very sharp.

Stopping the slippery Xiao Ding, he held the handle of the dagger in his right hand and groped beside him with his left hand, trying to find a starting point.

Fortunately, this is the path that everyone has climbed several times just now, and several protruding rocks that can be landed are not far from Xiaoding's side. After several efforts, Xiao Ding's feet finally stepped on the landing point. At this time, the hearts of the soldiers fell slightly.

Everyone shouted together: "General Tian, come down first!" "They were all worried that Xiao Ding would have an accident.

Xiao Ding saw the difficulty of rock climbing, and he didn't want to continue to climb up the risk, so he cautiously climbed down the cliff.

Returning to the bottom of the cliff safely, Xiao Ding frowned, looked at the cliff carefully again, and his head turned rapidly, thinking about how to climb the cliff.

"If only I could fly up!" A soldier muttered to the side.

Yes, if you can fly up, it will be much easier, but how can you fly up? Xiao Ding pondered secretly.

If it was in the later life, it would not be difficult to fly to the top of this mountain cliff, but now it is ancient times, and there is no such advanced equipment and technology as in later generations.

Thinking of the future generations, Xiao Ding's eyes suddenly lit up, and he remembered that when he was in the army, he usually practiced the launchers and flying tiger claws used when climbing high-rise buildings. Although there are no launchers and flying tiger claws in this era, he has a crossbow in his army!

Thinking of this, Xiao Ding suddenly brightened. Hurriedly sent people to the camp to push a few crossbow carts over. The soldiers also seemed to understand Xiao Ding's intentions, and happily ran back to the camp.

It didn't take long for the soldiers to bring in more than a dozen crossbow carts. This crossbow cart is a large crossbow arrow improved on the basis of the Xiaoding Lianzhu crossbow, which can fire a spear that is very long, and the power is huge.

Xiao Ding ordered the soldiers to tie ropes to several spears, and then used the dozen or so crossbow carts to fire spears at the cliff wall above.

Sure enough, after more than a dozen spears were fired, several of them were shot into the cracks in the stone wall and stuck, and a few of them were stuck on the rocks although they did not hit the cracks. The soldiers tugged at the ropes that were being hung on, and felt that they were hanging very firmly, and some of them were eager to climb up.

Seeing that this method was feasible, Xiao Ding took the rope and led several soldiers to take the lead in pulling the rope and climbing towards the top of the cliff.

This time, thanks to the rope assistance, the climb went a lot smoother.

The mountain cliff can have a height of more than 30 zhang in total. The Lianzhu crossbow that was launched did not shoot directly to the highest part of the cliff, so when Xiao Ding pulled the rope to climb to the end, he was still a few feet away from the top of the mountain. Xiao Ding took out the beaded crossbow he had brought with him, tied the rope he had brought with him to the crossbow arrow, and then launched it towards the top of the mountain.

Although the crossbow carried with him is not as powerful as the repeater car below, it is only a few feet away and can still be fired.

After shooting several times in a row, the crossbow arrow finally got stuck between the rocks at the top of the mountain, Xiao Ding pulled the rope, and when he saw that it was firm, he continued to climb towards the top of the mountain.

However, he didn't dare to push too hard, and although his crossbow bolts were made of iron, he was also worried that the crossbow arrows would not be able to bear his weight.

With the help of ropes, Xiao Ding quickly climbed to the top of the mountain.

Standing on the top of the mountain, looking down condescendingly, he felt more and more that the plan he had in mind could be implemented.
