Chen Jin said: "If a thick iron nail can be made that can be driven into the cracks in the rock, when the first soldier climbs to a certain height, he will first drive the thick iron nail into the crack in the rock, and then tie it with a rope.
On his own body, the other end was tied to a thick iron nail driven into a crack in the rock.
For safety reasons, a few more thick iron nails could be driven in while he tied another bundle of rope to a thick iron nail driven into the crack in the rock.
After the iron nail is hit, lower the rope, and the soldiers below can You can climb up through this rope, and when you reach the same position as him, you will give him a bundle of ropes.
After receiving the new rope, he continues to climb up.
When he reaches another height, he continues to hammer nails into the rock cracks and It turns out that the rope is tied to the newly made iron nail, and the people below can use this rope to climb up.
It is like a relay race.
Each climbing soldier must carry a bundle of rope until Pass the rope to the first soldier to climb."
"This requires three requirements: first, the first soldier to climb must have extremely high climbing ability, be flexible and react quickly; second, the rope must be strong enough; third, ordinary iron nails cannot be driven in In the cracks of the rock, it will bend when hammered, and the iron nails we need must have extremely strong drilling capabilities."
"This is indeed an excellent method."
Zhang Bi's face lit up when he heard this.
He thought for a while and said, "Since ordinary iron nails are not tough enough, then we will ask the blacksmiths in the siege camp to make steel nails for us. " Chen Jin added: "General, my subordinates have gone to see that cliff.
Only the lower half of the cliff has no slope.
The upper half still has a relatively sloping slope.
As long as we climb to the upper half safely, the remaining The second half of the cliff is much easier, and there is nothing on the cliff in the second half.
The subordinates found that there was something on the cliff.
Thirteen trees of different thicknesses grow, approximately between thirty-five and forty feet, and are arranged horizontally.
The first soldier to climb can be tied with a crossbow as long as he climbs to a certain distance.
The rope of the iron hook shoots up and the hook hooks the tree trunk, then it is not very difficult to climb this cliff."
"There is no perfect road, hahaha."
Zhang Ben was overjoyed and said, "Look, look, as long as we are willing to observe and use our brains, we can think of a way to pass on the order and prepare a climbing set for all the soldiers."
In addition to weapons, each person should not wear armor, as it is too heavy and is not conducive to climbing.
In addition, everyone needs to prepare a repeating crossbow and dagger.
One quiver, five quivers, and a bundle of ropes.
From now on, I need the correct height figures from the river to the top of the cliff.
I will find them immediately for my general to calculate and select the thirteen with the strongest climbing ability among the entire army.
They will be our first people to climb the cliff.
Send people to the siege camp and tell them that we need thick steel nails made of steel, and the steel nails must have buckles.”
After an afternoon of discussion, the Huya Army finally had a mature tactical idea for sneaking into Jinding Pass.
After dark, Zhang Bi immediately came to the Chinese army's tent to report to Zhao Ziliang after dinner.
At this time, Zhao Ziliang was folding his arms and looking at the map.
This was a map of all of Tubo.
Of course, his vision would not be limited by a small Golden Summit Pass.
But for now, breaking through the Jinding Pass is the prerequisite for the next step of the strategy.
Due to the vast territory of Tubo and the sparse population and towns, the Tubo people live relatively scattered in various places.
Even Luoxue City in Tubo now only has tens of thousands of people, and other densely populated areas are only the size of a small town at most.
This has advantages and disadvantages compared with the Western Qin Army.
The advantage is that it is more difficult for the Tubo people to gather a large army to fight against the Western Qin Army.
The disadvantage is that the Western Qin Army needs to spend more energy and manpower to rule the various places they occupy due to the sparse population.
Too difficult to manage.
However, for now, the Tibetan people living in the two places along the Yalu River are the most densely populated.
This river is the mother river for the Tibetan people, and most of the Tibetan people were born from this river.
Therefore, fighting along both sides of the Yarru River is currently the fastest way to eliminate the Tibetan military power.
"Your Majesty, General Zhang Ben, the commander of the Tiger Tooth Army, is asking for an audience outside the tent."
A small colonel walked into the tent and reported with fists in his hands.

"Let him in," Zhao Ziliang said, looking at the map.
"yes" Zhang Bi walked in and saluted with clasped fists: "The humble minister pays homage to the king."
Zhao Ziliang touched his chin and thought, turned around, walked behind the desk, sat down, looked at Zhang Bi and asked: "Without courtesy, Zhang Bi, why are you here to see me like this?"
Zhang Bi said: "Your Majesty, I have gathered my generals to discuss it for a day.
We believe that the only way to get to Jinding Pass is to sneak in from both sides.
It is basically impossible from the front.
Detouring from other places is time-consuming and difficult.
Cover your whereabouts.
If the Tubo people discover your whereabouts, sneak in secretly.
It would not work.
Sneaking in from the cliff on the left and from the mountain stream on the right are both very difficult, but it is not insurmountable.
After discussion, the ministers decided to divide the Huya Army into two parts for the sake of safety.
Climb from the cliff; climb all the way down the mountain stream on the right."
Zhao Ziliang nodded and said: "I'll take a look at the cliff facing the river on the left.
It's really difficult to climb.
If you fall down accidentally or after exhaustion, you may lose your body and bones.
It's very dangerous.
Extremely high.
How do you overcome the difficulties of too steep a slope and too high a climbing distance?”
Zhang Bi immediately walked to the map and pointed his finger at the plan on one side of the cliff, and said: "Your Majesty, please see, we first find a dozen soldiers with the strongest climbing ability.
They will stop every ten feet, and then A large hole was made in the cliff, and special steel nails were used to push it against the cliff.
These first batch of soldiers carried hammers, a large number of special steel nails and two bundles of A ten-foot-long tough rope.
After driving in the first steel nail, they tied one end of the rope to the steel nail and the other end to themselves.
In this way, even if he slipped and fell on the next climb, You won’t fall to death unless the steel nails are not firmly nailed.
Three steel nails are driven in every time to ensure that they are strong enough and that they will not be pulled loose and fall.”
"The remaining bundle of ropes is also hung on one of the steel nails.
Throw it down so that the soldiers below can tie it to themselves and protect them when they climb.
When the first batch of soldiers ran out of ropes They must stop and rest while the soldiers below climb up to deliver them ropes, two bundles at a time.
Therefore, before each soldier starts climbing, They had to carry Liang Kun's rope in front of them, so that the ropes could be passed upwards one by one.
After receiving the new ropes, the first batch of climbing soldiers tied one end to a steel nail and the other end to themselves before continuing to climb up.
This is the same as before.
The relay is average, and another advantage of this is that everyone can stop and rest in the middle, and reinforce the steel nails at each place."
"Your Majesty, please see, there are thirteen big trees growing on the cross section of the lower half of the cliff at a distance of thirty-five to forty feet.
These big trees can grow on the cliff and are blown and suppressed by wind and snow all year round.
They are all so thick, their root systems must be very deep, so it They should be strong enough.
As long as the first batch of soldiers climb to a distance of ten feet from them, they can use crossbow arrows to tie ropes and shoot them up to wrap around the tree trunks.
This is good for climbing.
Tie the ropes to the tree trunks.
At the base, the soldiers can pull the rope to climb."
"In addition, Your Majesty, look at the upper half of this cliff.
It has some slopes.
Although its slope will not be less than 70 degrees, there should still be 80 degrees.
As long as there is a slope, our soldiers are climbing It’s much easier to climb.”
Zhao Ziliang smiled after listening to Zhang Bi's explanation and said: "The method you thought of is good.
It can not only protect the safety of the soldiers to the greatest extent, but also allow them to rest and accumulate strength during the climb.

But this is The steel nails must be able to be driven into the rock, at least they must be able to be driven into the cracks in the rock.”
Zhang Bi said: "Yes, so I asked the king to order the logistics department to allocate a special steel block to make this kind of steel nail.
In addition, all the buckles on the climbing equipment used by the soldiers should be replaced with this special steel block."
Made of high-quality buckles, this is the only way to ensure safety.”
Zhao Ziliang agreed: "Okay, you go to Zheng San and say that I agreed."
"Thank you, Your Majesty" Zhao Ziliang asked again: "Then how to climb down the mountain stream on the right?
I heard that the mountain stream is covered with moss, and there are thorns, thorns and shrubs everywhere.
There is no road at all, and some places are even at an inverted angle. , the height reaches more than ten feet, which is not good for climbing.”
Zhang Bi said: "Your Majesty, we have thought about this problem.
We decided to send advance team members to open a way.
Your Majesty gave us six days.
Wei Chen thought that this time should be enough for us to send people to open a way from the mountain stream.
Although the top is covered with moss, thorns and thorns, there are trees everywhere.
You can use these trees and ropes to climb.
As long as you have a strong point, you can climb.
The only thing worth worrying about is that you need to cut down trees when opening the road, which may cause movement.
However, we will ask the advance team to try to avoid too many trees.
In dense areas, only cut down some thorns and spikes to reduce the sound."
Zhao Ziliang thought for a while and agreed: "Okay, I will order to strengthen the frontal offensive, attract the attention of the Tibetan army to the front, and create conditions and opportunities for you to sneak in."
Zhang Bi saluted and said, "Thank you so much, Your Majesty."
Zhao Ziliang asked: "Do you have any other requirements?"
"Your Majesty, I have no other demands.
Marching and fighting is the duty of our soldiers.
No matter how dangerous it is, we must go."
Zhao Ziliang thought for a while and shouted outside: "Come here, send a message to Zheng San and ask him to send a batch of meat and wine to the Huya Army."
After shouting, he said to Zhang Bi: "Let the soldiers eat and drink enough and recharge their batteries in the past few days.
When you feel that everything is ready, you can start on your own.
You don't have to wait for the deadline to pass before taking action."
"Yes, Your Majesty":
