Qian Mu now knew what to do.
But there is a problem. They have tried this method before.
"General Liu, we've tried this method before. It works fine at first, but it falls off after a few months, and it's even cost several lives."
"People crossing the chasm thought the cable was secure, but when they exerted force, it broke free and they fell off the cliff."
"If it's used this time, it's completely sufficient. But if it's used long-term, it won't be a permanent solution."
Liu Feng laughed.
This is not difficult. He is Liu Feng. Can this little problem stop him?
"It's simple. I have my own way."
Qian Mu's pupils shrank, and he asked hurriedly, "Is what General Liu said true? Is there really a way?"
Liu Feng laughed and said, it’s just a rope, what’s so difficult about it.
Liu Feng has walked back and forth on the chasm several times.
The rock of this section of the cliff where the natural barrier is located is soft in texture. If iron nails were driven into the rock wall, they would surely fall off in no time due to the horse-drawn people pulling them back and forth.
The solution is also very simple. How the new era solves these problems is to add expansion screws.
Although current technology cannot produce expansion screws, it is possible to add some wood chips inside.
In the new era, rural areas have encountered these problems during the construction of houses, and it is common to use wood chips as expansion screws.
And wood chips have another advantage. Wood has good flexibility and elasticity. As long as you stuff wood into the small hole in advance and then hammer in the iron nails, the service life will naturally be extended.
There is also the issue of widening, which is also simple. Just set a fire at the location that needs to be widened, and then pour water on it, and the problem will naturally be solved.
It was just a small guardrail, but it was very important for Qian Mu who was trapped in Zadasan Pass.
Why did the imperial court trust Qian Mu so much? It was because of the special terrain of Dasan Pass.
If Qian Mu wanted to rebel, he had to attack through Qingzhou.
But Qingzhou is an important grain-producing area, and heavy troops are stationed in almost every city. How can he rebel?
The road from Youzhou to Yanzhou was blocked by natural barriers, making it impossible to march on a large scale, and transporting food and supplies was even more impossible.
It is impossible to even allow the army to enter Youzhou normally.
Liu Feng naturally saw this key point.
Since this is the case, it wouldn't hurt to give Qian Mu a little benefit for such a small matter.
After all, if salt fields or mineral veins are discovered in the mountains around Dasan Pass in the future, they will need to rely on this natural barrier for transportation.
Of course, if these two most important strategic materials are really discovered in the future, Liu Feng will consider carving out a cliff-hanging road on the mountain wall of more than ten kilometers to allow horse-drawn carriages to pass.
If you calculate the straight-line distance, Dasan Pass is not very far from Tianyong City, but it is blocked by these continuous mountains.
What is even more difficult to pass is that whether it is Longshou Mountain or the mountains surrounding Youzhou City, they are all folded mountain ranges with many cliffs. The only way for people to walk is the natural passage today.
If a cliff-hanging road is built on the rock wall based on the current passage, everything will be solved.
But these are all plans for the future. Now, let’s not waste this time.
Let’s solve the problem of the safety rope first.
Of course, to make a safety rope, the traditional rope used in the past will not work. If Liu Feng wants to make it, he must make a steel cable so that it can be used for a longer time.
"Don't worry, General. Leave the construction of the safety rope to me."
"Well, General Liu, you are so quick to speak. If you can really solve this problem, Qian Mu will be very grateful."
Qian Mu raised his glass with a smile.
He secretly muttered in his heart that it was worth marrying off this niece. Before she even got married, she had solved a big worry that had been bothering him for so many years.
It doesn't take much effort to make iron nails, they are available inside Dasan Pass.
Moreover, Qian Mu had tried it before, so there were quite a few small holes left where iron nails were hammered in.
Now we just need to prepare the other materials.
So early the next morning, Liu Feng wrote down what was needed and gave it to Qian Mu to purchase.
In the past, these matters would have been handled by An Shirong, but this guy faced Liu Feng's aggressiveness in the study and had no choice but to cut off one of his arms.
I am still bedridden and have no way of participating in the big events at home.
Qian Mu had no choice but to transfer two of his other advisers to Liu Feng.
After receiving the order, the two men went out with a few guards.
At this moment, Liu Feng was already waiting on one side of the chasm.
Liu Feng climbed up the natural ravine. All traces of the siege of the Black Tortoise Armor had been cleared away, and not even a single corpse was left.
It is said that these bandits are well-developed and have very strict command. Their military secrets are tight. If they were ordinary bandits, they would definitely take away the Xuanwu Armor equipment.
But these bandits didn't, they didn't take anything, which was strange.
It seemed as if their only purpose from the beginning of the ambush was to kill people.
Liu Feng listened to the discussions of several advisers under Qian Mu, and was still somewhat dissatisfied with Linghu Zheng.
It's a pity that Linghu Zheng was careless in doing things and didn't make them foolproof. This flaw was too big.
Is he waiting for me to clean up his mess?
"These bandits may have concerns. Think about it, this place is only more than an hour's journey from Dasan Pass. Perhaps the bandits were worried about being discovered by Dasan Pass, so they left in a hurry without taking anything."
Liu Feng began to talk nonsense seriously.
These counselors all knew one thing: Liu Feng was the nephew-in-law of their general and was extremely popular.
What’s even more terrifying is that one of the arms of An Shirong, the general’s top strategist, was removed.
They were both afraid of and admired Liu Feng, so at this time, whatever Liu Feng said was the truth, and there was no need to refute it. Even if Liu Feng called a deer a horse, they would think that the deer was a horse.
The safety rope was installed very quickly. With the help of more than 300 soldiers, it was all installed in just one afternoon.
After Liu Feng installed it, he went up to try it out. It was very stable and strong. Now it can be used for three to five years without any problems.
At that time, someone will be sent to conduct regular inspections and repair any problems, so that the service life can be extended.
If current technology had not reached the required level, Liu Feng could have made it even more sturdy.
If it were made into steel nails for rock climbing and hammered in, the effect would be many times better than it is now.
But then again, if Liu Feng really succeeds in doing it, others will think it is not a product of this era. If the technology is leaked, it will only cause more trouble.
After the cableway was completely completed, several of Qian Mu's advisers praised Liu Feng to the skies, almost kneeling on the ground to lick his praises.
After listening to the reports from several advisers, Qian Mu felt even more grateful to Liu Feng. He immediately ordered a celebration banquet and insisted on having him and Liu Feng drunk.
Several counselors who worked with Liu Feng were rewarded with 100 taels of silver each.
