The mountains stretch out, and the forts are large and small, standing against the mountains. These forts are all in the dangerous terrain and are built by stones. They are extremely sturdy and have ingenious locations. It is difficult for outsiders to use artillery to aim directly at these forts that look like small towns.

The so-called foreigners in the mountains refer to the Zhou army, while the guards of the large and small fortresses were Goguryeo soldiers. They wanted to attack the invading Zhou army in this area called "Wangchuan".

More than ten years ago, in the first war between the two countries, Goguryeo suffered a great loss. The once-sturdy mountain city could not last long in front of the new long-range weapons (artillery) of the Zhou army.

So over the past ten years, Goguryeo summed up the experience and lessons, and built a large number of easy-to-defense and difficult-to-attacks in the mountains northeast of the country. Once the Zhou army invaded again, they would rely on these areas to offset the offensive advantages of the Zhou army and make the war long-term.

The fortress group in the Wangchuan area is a defensive system carefully constructed by Goguryeo. It is located in the mountainous area in the eastern upper reaches of the Sashui River. It is difficult to walk by just entering the Wangchuan area from the riverside.

When we arrived at the edge of Wangchuan, there were not many large flat land camping. If tens of thousands of troops came in, we could only ship the long snake formation in the narrow mountains and rivers, and we could not exert our military advantage at all.

Even if you attack the Wangchuan area, the mountains are high and dense, and there are steep slopes everywhere. If you are not careful, you will get lost and forget which one you came in. This is also the origin of the Wangchuan name.

The ready Goguryeo army guarded the Wangchuan area, waiting for the Zhou army to crash into death, but after the Zhou army arrived at the upper reaches of the Sashui River, they delayed attacking the Wangchuan area.

The other party was only stationed in the marginal areas, and the Goguryeo soldiers were on high alert, but they did not see the other party take further measures.

In the early morning, in a simple beacon tower on a mountain peak, the Goguryeo defenders were gnawing dry food. While gnawing, they looked south to see if there was any movement at the mountain pass. Once the Zhou army attacked, they would light the beacon smoke and beat drums to warn them.

The peak of this beacon tower is very steep and difficult to get up and down, so it is a hard job to stay on the mountain. Food and water have to be transported slowly by people.

There are trees on the top of the mountain, which are not tall but very dense. The soldiers set up a simple beacon tower on the top of the mountain, then pulled ropes among the trees and set up tents to take shelter from the rain, and live.

If you want to leave, you will naturally come to the cliffs on the edge of the mountain, tie a rope around your waist, squat on the wooden platform, and "convenient" to the outside.

Because it is very hard to keep watch on the mountain, the soldiers took turns to go up the mountain to squat. As the deadline is approaching, a new group of people are about to come up, and the sentries are looking forward to it.

The rising sun rose, and the thick fog in the mountains gradually dissipated. The mountain where the sentries were located was hundreds of steps south, a lonely peak that looked like a pillar appeared. The lonely peak was slightly higher than the peak where the beacon tower was located, and it was steep on all sides, and only monkeys could climb up.

So even though the coach had considered setting up a whistle on it, he finally gave up.

The sentries looked at the familiar lonely peak and suddenly felt something was wrong: birds flying in the mountains, not falling on the lonely peak.

There are small woods on the lonely peak, and there were many birds inhabiting each other in the past, why have they been...

But I saw the fire flashing on the lonely peak, and at the same time, there was a thunder sound.

"Boom, boom, boom!"

An explosion occurred on the hill where the sentrymen were located. The Goguryeo soldiers caught off guard were surrounded by fire and thick smoke. The beacon towers and fragments were broken, and the remaining limbs of the plants and trees flew randomly.

Not long after, there was another flash of fire on the lonely peak, mixed with thunder, causing the mountain where the sentry was located to be covered by explosions again.

In just a moment, the sentry suffered heavy casualties, and this emergencies also caused the defenders of Shanxia Fortress to boil.

Many people looked up and saw another flash of fire on the lonely peak. Then the flames rose into the air, pulling long smoke, drawing arcs in the air, landing on the beacon tower on the top of their mountain.

The specially made rocket, dragging long ropes, crossed hundreds of steps, landed on the top of the mountain where the beacon tower was "cleaned" by artillery fire. The bullet hit the ground and rolled downwards. The hooks popped up on it quickly caught branches, trunks, and cracks of rocks.

As the rope at the end tightens, the hook on the bullet body tightens to any object that can be hooked.

Long ropes connected the two peaks, and the ropes were relatively higher than the other end of the lonely peak. After a while, each rope suddenly stretched out, and a huge sack slid along the rope after a moment.

These are some large sacks hanging on pulleys, with heavy objects at the bottom, which make them slide from high to low, and finally hit the hill where the beacon tower is located, making a muffled "bang bang".

It seems that although the sack is big, it is filled with many fluffy objects. Several large sacks slide over each long rope and gather at the end.

The sentries who were lucky enough to die were about to step forward, but they saw someone slid over the other end of the rope.

These people were dressed in black, had hideous blue patterns on their faces, and were tied with thin ropes on their waists. One end of the rope was a pulley hanging on a long rope. They crashed into this side at an extremely fast speed, but they hit the soft sack without any serious damage.

It turned out that these sacks were used for buffering, and the person who slid along the rope was undoubtedly Zhou Bing.

The sentries wanted to step forward and cut the rope off, but the Zhou soldiers who came over the zipline used "Six Singzis" to solve the problem one by one. They quickly climbed the top of the mountain, untied the safety belt around their waists, and used the tools they carried with them to strengthen the "anchor point" of the rope.

After a while, someone set out from the lonely peak and reached the top of the mountain with ziplines. In a short while, there were dozens of people.

The speed of his movements was beyond the expectations of Goguryeo. Many soldiers who climbed to the beacon towers on the hill did not even reach the middle of the mountain.

Zhou Bing, who came with the help of ziplines, quickly completely controlled the top of the mountain and began to set up defenses, attacking the Goguryeo soldiers who were climbing the mountain below from a high place. After a while, dismantled artillery parts arrived from the cableway.

Several light cannons were then set up on the top of the mountain, and Zhou Bing operated these cannons to shoot the Goguryeo Fortress in the valley from a high place.

This kind of attack that fell from the sky was simply unable to defend against the Goguryeo side.

The forts they built came along the mountain road, and no one expected that when the enemy really came, they would actually take the "heavenly road".

No one would have thought that the Zhou army would have incredible means to build a cableway between two steep peaks, and then use it to transport soldiers, weapons, occupy high places, and wantonly attack the fortresses in the valley.

In the middle of the Fortress in the core area of ​​the Fortress, a group of Goguryeo generals were anxious to mobilize their troops to do their best to block the upcoming attack of the Zhou army at the mountain pass, but the mountain that had been controlled would be a fatal wound.

This wound cannot heal and will also "destroy" the surrounding area, causing the entire Wangchuan area to be lost.

On a lookout building, several Goguryeo generals stood, each using a thousand-mile mirror to look at the peaks that were constantly flashing with fire, and then watching the explosions in the valley. Listening to the tide-like sound of horns at the pass, his face was bloodless, and he murmured:
Chapter completed!
