Time is of the essence.

Mickey Leader knew very well what it meant for the Ming army to cross the canyon quickly. Without hesitation, she personally led ten warriors of her own clan to lead the way for the chasing troops led by Luo Shiyin and Luo Shangzhi, so that they could safely climb the protruding boulder located on the cliff from a secret path.

Standing on the boulder and looking at the opposite cliff, about ten meters away, on the opposite cliff, a boulder that also protrudes stands impressively. The two protruding boulders were like two big hands stretched out to each other by two giants standing proudly, but as soon as these two big hands stretched out their sleeves, they did not continue to stretch forward, and they continued to be reserved for a hundred, a thousand years, or even longer.

Led by Mickey's leader, the Aborigines at the scene held a brief prayer service.

At the end of the ceremony, Mickey turned and walked to the cliff behind him, pressing his right hand against a less obvious pit in the cliff.

With a loud rumbling sound, a heavy stone slab slowly moved away, revealing a cave on top of the cliff.

The ten Native warriors who accompanied him walked into the cave at the signal of Mickey's leader.

After a while, the warriors lifted out of the cave a long bamboo ladder more than ten meters long and more than one meter wide, and a rectangular wooden frame with two wooden wheels, which were installed in the middle of the wooden frame, and the outer edge of the wooden wheel happened to be on the same plane as the four square logs on the wooden frame. On each side of the wooden wheel, there is a wooden crank. On the crossbar at the front of the wooden frame, a tall square shelf resembling a gantry crane is attached, and a pulley is hung in the middle of the beam at the highest part of the shelf.

The indigenous warriors first placed the wooden ladder near the edge of the boulder, and after confirming that it was correct, they placed the long ladder in the middle of the wooden frame, so that the long ladder was pressed against the top of the two wooden wheels.

Another warrior threaded a long hemp rope through a pulley above the gantry crane and tied one end of the hemp rope firmly to the front of the ladder.

When everything was ready, the four indigenous brothers shook the handle of the wooden wheel vigorously. As the wooden wheel turns, the long ladder pressing on it slowly stretches towards the boulder of the opposite cliff.

In order to prevent the ladder from falling into the canyon, another indigenous warrior is responsible for holding the hemp rope with both hands, and using force at the right time, through the pulling effect of the hemp rope, the front end of the ladder is always controlled in the horizontal direction.

On the opposite side of the boulder, there is a groove that has been hand-hewn out of the sky, just wide enough to fit a long ladder.

In the same way, there is the same groove on the boulder where everyone is standing, and the long ladder is placed firmly in the two grooves.

After the ladder was placed, the ten indigenous warriors returned to the cave and removed a dozen planks with locks from the cave and arranged them on the ladder in turn. The width of the plank is equal to the width between the two inner edges of the ladder, and it sits firmly on the ladder so that it does not sway from side to side. In addition to this thoughtful design, there is a wooden latch underneath each plank that locks the beam of the ladder below.

In less than two quarters of an hour, a wooden bridge that was perfectly conceived, designed, and manufactured was built between two cliffs.

Obviously, all this, including the caves on the cliffs, is the result of the wisdom of the indigenous brothers.

After the wooden bridge was built, one of the indigenous brothers carried a bundle of twine as thick as a fist from the cave and, with the help of another companion, carried it diagonally over his shoulder.

The crowd dodged a way. When the native, who was carrying a hemp rope, came to the wooden bridge, he first stretched out one foot to test the stability of the wooden bridge. After confirming that there is no problem, he immediately stretches out his arms to maintain his balance, and then moves his legs and deftly steps onto the wooden bridge.

Under the gaze of everyone, in less than a minute, the indigenous brothers with hemp ropes on their backs were already standing firmly on the boulder on the cliff opposite.

Having steadied himself, the native brother mischievously grimaced at the nervous crowd across from him, and then removed the hemp rope that was leaning on his body and placed it on the boulder. Seeing him, he adjusted his position and looked up at the top of the cliff.

At this time, Luo Shiyin and others discovered that at the top of the cliff nearly ten meters away from the boulder, a vigorous ancient pine tree was stretching diagonally upwards in the direction of the canyon.

After confirming the relative position of Honka and his body, the indigenous brothers on the opposite side untied the bundle of hemp rope on the ground with both hands, and then, holding the hemp rope with both hands, threw the end of the hemp rope tied to the stone to Honka at the top of the cliff.

The stones, with hemp ropes, made a beautiful arc in the air, through the trunks of the ancient pines, and fell downward.

The native brother kept loosening the hemp rope in his hand. Pulled by the weight of the stones, the other end of the hemp rope slowly fell close to the boulder.

The native brother raised his hand and pulled down the hemp rope tied to the stone, took out the stone, and joined the two hemp ropes side by side to form a dead knot.

"Alright, Yingzi. Your friends can safely cross to the opposite side and climb the rope to the top of the cliff. At the top of this cliff there is a south-facing trail down the mountain. Seeing that his subordinates had arranged everything, Mickey said to Jin Yingzi. 168

"Mickey Chief, thank you for your help!" Kim Young-ja said gratefully.

"It's all a family, don't be so polite. However, Yingzi, these climbers are all the work of men. I think it's hard for your body to climb the cliff on the other side. You might as well stay with me for a few more days, so that I can treat you well. Mickey Leader said.

"Yes, Miss Yingzi, this time we are going to march in a hurry to catch up with the enemy, you might as well stay here for a few days, and when the mission is completed, we will pick you up and go to Pyongyang together." Luo Shiyin said.

"Yes, Yingzi. This march is no joke. Listen to the adults and stay and catch up with Mickey Chief. Ye Ruliu said.

"That'...... All right. Sister, I listen to you. Be sure to pick me up then! Jin Yingzi glanced at the cliff opposite and knew that it would be difficult for him to climb up, so he had to agree to stay.

After thanking the leader of Mickey one by one, Luo Shiyin, Luo Shangzhi and Abbot Xiu Neng, they led the troops to cross the narrow wooden bridge, climb the cliff with ropes, and smoothly descend to the bottom of the mountain.

In a dense forest at the bottom of the valley below, Luo Shiyin and Luo Shangzhi ordered the team to stop resting.

At this time, it is almost dusk, and the team members who have been tired all day must stop to replenish food and regain their strength.

Taking advantage of this short rest time, Luo Shiyin, Luo Shangzhi and Xiu Neng decided through consultation: after the team rested for half an hour, they immediately set off overnight to rush to Sanhe Cave; Hunneng sent three disciples with his handwritten letter to Dulong Peak to ask for help from the Huang brothers.

The origin of the place name Sanhedong is actually very simple, the tributaries of the three Longchuan rivers cross the mountains and cross the mountains to flow into the Longchuan River after confluence in this place, so it is called Sanhedong.

The Sanhedong section is located in the low-lying valley area, the tributaries of the three Longchuan rivers meander down from the high mountains in the east, north and west directions respectively, and in the river valley surrounded by the three mountains, they converge into a river with a width of nearly 10 meters, and the rushing river water flows down more than 30 meters to the south, bypassing a huge sedimentary rock, and injecting into the rolling Longchuan River.

The only stone bridge sits on the upper right of the sedimentary rock.

When Luo Shiyin, Luo Shangzhi and Abbot Xiuneng led their troops to the stone bridge in Sanhedong, it was already noon three days later.

Standing on the huge sedimentary rock and looking down to the right, the turbulent Longchuan River flows through the area, and the surface of the river suddenly narrows. The rushing water was suddenly squeezed by the rocks on both sides of the river, and it became more and more turbulent.

The stone bridge is located at the narrowest part of the river, it is a single-arch stone bridge with a small arc, due to disrepair, the two rows of railings on the bridge deck have been incomplete, making the entire bridge deck about 10 meters long look a little dilapidated.

"It seems that Captain Konishi's team should not have crossed the bridge yet." Luo Shiyin stood on the rock, looked at the stone bridge not far in front of him and said.

"Yes, probably not. According to the cunning and insidiousness of the Japanese, if they knew that there were pursuers after they crossed, they would definitely destroy the bridge. Judging by this, we are still ahead of them. Hunneng said.

"Great, we'll ambush them here." Luo Shangzhi said with some excitement.

"Let me see, just tear down the bridge. Wouldn't that be a hundred, and completely cut off the retreat of the old boy of Konishi Yuki. Shi Tianji had a whim.

"Lao Shi, don't forget, we are here to destroy the enemy. If you tear down the bridge, won't Yukinaga Konishi turn elsewhere? Once his more than 4,000 retainers hid in the mountains and started a guerrilla attack with us, it is really hard to say whether they can be completely wiped out! Shi Lang disagreed with Shi Tianji's suggestion to demolish the bridge.

"Yes, what Shi Lang said makes sense. This time, we will try to eliminate Yukinaga's forces in this small area. If we let them run into the mountains to fight guerrilla warfare with us, first, it will be difficult to clear out; The second is that if their reinforcements arrive, they may take the opportunity to run away. Luo Shiyin said.

"Yes, your analysis makes sense. I just looked at the nearby terrain, and on the opposite side of the bridge is a low date forest, and to the south of the date forest is a steep mountain.

"You see, my lord, this steep mountain area has blocked off the entire road to the south, and only a winding path in front of it leads to the top of the mountain.

"We might as well ambush a group of ambush soldiers on the mountain opposite the bridge, let Konishi Yukinaga's troops cross the bridge, and on the south side of the bridge, make full use of the steep mountain terrain to block or even destroy them." Luo Shangzhi said to Luo Shiyin.

"Yes, Lord Luo. We ambushed a part of our forces on the steep hills, believing that with this dangerous place, it would be difficult for Konishi's troops to pass.

"At the same time, in order to prevent Konishi Yukinaga's troops from retreating north and escaping into the mountains, we will also take out some of our troops and ambush them in the mountains and forests on the mountain peak on the north side of the stone bridge. Once Konishi Yukinaga retreated and fled north after a long attack on the mountains on the south side of the stone bridge. The part of the ambush force can also stop them with all their might. Luo Shiyin said.

"Yes, our troops are divided into two routes, and the north and south are flanked. I will definitely throw this old boy into the Longchuan River to feed the fish. Luo Shangzhi said.
