But the hilltop must be transformed, otherwise it will be bare and without cover. Firstly, it will be threatened by enemy arrows. Secondly, the enemy will definitely besiege the place. By then, just the scorching sun in the sky will be enough for Qin Feng to drink. A pot of it.
Moreover, the terrain is steep, but it is not an insurmountable chasm. On the contrary, it is possible to go up the mountain from all sides, and it is a certainty that it will be besieged on all sides.
Qin Feng took a deep breath and said resolutely: "Cut the mountain and transform it!"
"Turn this mountain into a desperate situation on three sides, defend it from the enemy on one side, and build fortifications on the mountain to fight a protracted war with the enemy!"
Ning Hu was stunned when he heard the word "Mountain Cutting and Transformation", and it took him a long time to come back to his senses.
"Brother Qin, did I hear you right? Chopping the mountain? We don't even have the tools, how can we chop the mountain? And... this is definitely a big project. It can't be completed in less than ten days and a half, and the enemy will never do it." We will be given so much time to prepare, and we estimate that the enemy troops will surround Qingyu Mountain in two days at the latest and one day at the earliest."
Ning Hu's doubts are not without reason.
But who said you can’t cut mountains without tools? Who said that to cut a mountain, you need to dig it out bit by bit?
In this huge stone mountain, any stone weighs tens of thousands or even hundreds of thousands of kilograms. If it is excavated by manpower, it will take years and months of the monkey?
Qin Feng didn't know how to explain it to Ning Hu, so he simply didn't explain it and asked Ning Hu to go to the camp to call a few guards to get Bu Hu and the captured Bu Ge.
Qin Feng held a bu Ge and glanced back and forth on the top of the mountain, and finally chose a huge rock on the west side.
This big stone is itself part of the mountain. Two-thirds of it is submerged in the mountain, and only one-third is left protruding, just enough for people to climb by hand.
As long as this boulder is still there, the enemy troops who come up from the west can use it as a springboard to easily climb to the top of the mountain.
Under the confused gaze of Ning Hu and the guards, Qin Feng raised his gun and began to dig into the stone.
The appearance of this Bu Ge is like a pickaxe, but it is not as strong as a pickaxe. After all, its main function is to break armor.
With a clanking sound, Qin Feng dug a hole in the stone as big as a tiger's mouth without spending much effort at all, and then asked the guard to stuff the handle of the rifle into the hole. Then he followed the same pattern and dug a row of nine holes in the boulder along a line.
A handle was inserted into each hole.
Then he found a bunch of small wooden sticks, sharpened one end of the stick, and inserted it through the gap between the handle and the hole. If that doesn't work, use rocks and forcefully smash small wooden sticks in.
When the first pothole could no longer hold any sticks, Qin Feng turned to the second pothole and continued to repeat the behavior of the first pothole.
After filling eight holes in a row, Qin Feng came to the ninth hole and inserted a wooden stick. Seeing that there was still a gap in the hole, he found a slightly thicker wooden stick, inserted the tip into the gap, and lifted it. He picked up a stone and hit the other end of the stick hard.
Click!
The boulder suddenly made a clear and terrifying sound.
Ning Hu, who was standing next to him in confusion, his expression changed from confusion to shock, and finally to ecstasy, pointing at the huge gap with nine holes in the stone, extremely excited.
"Cracked! It actually cracked!"
The other guards present were also surprised. They didn't expect Qin Feng to be able to pry open a huge boulder weighing tens of thousands of kilograms with the help of a small wooden stick!
To everyone, this scene is like a miracle!
Qin Feng didn't hesitate at all. He raised the stone and smashed it against the wooden stick again. As the wooden stick went deep into the hole, it expanded the hole a little bit, but just this little bit became a crushing force. The last straw for the camel.
As the saying goes, a thousand-mile embankment was destroyed by an ant nest. The seemingly indestructible boulder completely cracked along the nine holes and split into two.
Half of the boulder that had been pried away slid down the mountain and hit the rock wall below, making deafening noises.
The guards on the mountainside were unaware of the situation and ran up one after another, looking confused.
"Ning Qianhu, what just happened?"
"It's thundering?"
"Oh, what a big dust!"
The guards who ran up all had blank faces, but the guards present were dumbfounded. It took a while before everyone came back to their senses.
Ning Hu swallowed his saliva and stammered: "Just now...Brother Qin just broke open the huge stone weighing tens of thousands of kilograms."
As soon as this statement came out, there was a moment of silence, followed by an uproar.
The guards who caught up had expressions of disbelief.
"What? Pry open that huge rock weighing tens of thousands of kilograms? How is this possible? Mr. Qin doesn't even have a decent digging tool in his hand!"
"The loud noise just now was indeed caused by the falling boulder. But how long has Mr. Qin been here? How could it be possible to pry it open? Even if you beat it with a pickaxe for a long time, you probably won't be able to pry it open, right?"
The guards who witnessed the entire passage still couldn't believe their eyes and replied indifferently.
"Young master... he only used a buge and a stick to pry the stone apart."
The guards who didn't know the truth were shocked.
When he learned that Qin Feng's tool to pry open the boulder was actually a small wooden stick that could be seen everywhere, he was even more shocked that his scalp was numb.
If there is anyone who disdains this feat, it is naturally Qin Feng himself.
Under the hot and astonished gazes of everyone, Qin Feng threw the stone aside casually, with his hands behind his back and a look of calmness on his face.
"The principle of this small wooden stick is actually very simple. It is commonly known as the 'exploding wedge'. The strength of a wooden stick is insignificant, but the nine explosive wedge holes can force the stone to explode. The stronger the stone, the more powerful it is." On the contrary, the fewer oblique holes are needed, and the looser the texture of the stone, the more oblique holes it will have. To put it bluntly, it relies on the rigidity of the stone itself to allow the stone to burst itself."
The wedge-exploding technology itself is an ancient technology, but it has not yet been mastered in this era. As far as Qin Feng knows, the quarrying methods of this era were to dig out small stones directly, and to burn them first and then pour cold water on them if they were large stones, using the method of thermal expansion and contraction.
However, for the guards who were exposed to the explosive wedge technology for the first time, this scene was still too shocking.
Ning Hu stared at Qin Feng blankly, and couldn't help but sigh: "Brother Qin, what is going on in your head? From the military to the merchants, you are proficient in everything. Now you can even dig huge rocks with the help of a god. This Is there anything in the world that you can’t do?”
The Jin Yiwei on the side silently recorded the wedge-exploding technique in a small notebook, and sighed in a low voice: "This is not a question of whether he can do it, but... Mr. Qin can always do some feats that are different from ordinary people. If he hadn't seen it with his own eyes, who would have done it?" Can you imagine that stone can be cut like this? It’s incredible..."
