Behind the mountain, in the narrow area on the edge of the cliff, the soldiers and craftsmen of the Tang Army, who were busy tightening the ropes and fixing the ropes, did not even notice the brute soldiers climbing from the middle of the rock wall below. Instead, some people saw someone on the North Shore waving and waving flags desperately, but they couldn't understand what they meant. The shouts of the soldiers on the other side were drowned out by the sound of the rushing water, and it was difficult to hear what they were shouting again.

The tragedy soon followed. The brute soldiers who arrived at the rock wall on both sides of the rope diagonally unloaded the bamboo tubes they were carrying behind their backs, stood on their toes in the protruding square inches, and their bodies were like four-clawed snakes clinging to the cliff wall, and they skillfully and quickly connected the folded bamboo tubes to a long blow pipe.

"Boom!" The sound of blowgun firing is hollow and faint, and it is impossible to detect it in an environment full of noisy sounds.

The soldiers and craftsmen of the Tang Army above the cliff were all in full swing with their armor off, and suddenly, dozens of people felt as if they had been bitten by mosquitoes, emitting a slight stinging pain. Some are necks, some are arms, some are chests, and some are thighs. They let out a soft 'oops' almost at the same time, but then there was no response, and their bodies fell to the ground stiffly, falling from the cliff face like a piece of log. Some fell straight down, bouncing off the taut ropes a few times, and then falling straight down to the rocks on the river beach below.

"Boom!" The blowing of arrows continued, and before they could understand what was going on, the Tang soldiers who were looking around in the same way fell dozens of them again like dumplings. The remaining 100 people realized that they had been attacked by an unknown attack, so they let out a cry and looked for a place to hide.

"Ada, come with me, climb up and cut the rope." In the middle of the cliff, a thin black-clothed brute soldier held a withered vine with a snow-white slender hand, and a pair of bright phoenix eyes were exposed above the black scarf covering his face, and turned around and gave orders to the group of barbarians beside him.

"Princess Aluo, don't take any risks, with us, how can you let Princess Aluo do it." A thin brute beside him whistled, took out a dagger and bit it in his mouth, and climbed up the rock wall as swiftly as an ape. Behind him, a dozen brutes climbed up with their hands and feet as if they were walking on the ground.

From the middle of the cliff to the top of the cliff only three or four feet away, they soon climbed to the bottom of the more than a hundred straight ropes along the cliff wall, climbed on the rock wall with one hand, and began to cut the rope with a dagger in the other. The Tang soldiers who were hiding above the rock wall and building a rope bridge finally saw the situation clearly, and they all got up and shouted loudly, carrying blades and spears and rushing to the edge to slash and stab the barbarians.

In the middle of the cliff, Princess Aluo bent her bow and arrows and shot at a Tang soldier who was on the probe above, hitting the throat of the Tang soldier, and the soldier fell down the cliff. The surrounding barbarians either used bows and arrows or blow arrows to shoot at the Tang army above, and dozens of Tang soldiers fell, and the rest had to shrink back and hide. Some soldiers had already quickly climbed up the steep mountain to the north to report to Song Jiangong, who was being attracted by the barbarian soldiers on the top of the mountain, who were being attracted by feints from three sides.

With a "buzz", the first rope was cut off, twisted and bounced like a long snake to the surface of the river, and a splash was struck on the surface of the river, and it hung like a dying snake on the opposite cliff and in the river.

Immediately after, there was a loud buzz, and one after another the ropes that had exhausted energy and strength to hold the taut ropes were cut off, and one after another the taut ropes twisted and shook and bounced towards the opposite bank, drawing traces on the surface of the water. Forty or fifty of the hundreds of ropes were cut in a moment. The nimble brute cut one and then quickly moved on to the other, vowing to cut all the ropes.

On the cliff on the north bank, from the moment he saw the figures of the barbarians on the opposite side moving horizontally along the cliff, Wang Yuan knew that they were coming towards the rope bridge. But across the river dozens of zhang wide, it is indeed beyond the reach of the whip. When the signal and flag could not make the Tang soldiers on the other side understand that there was danger below, Wang Yuan hurriedly burst into foul language, not knowing how to hinder the other party's sneak attack. Li Mi was also so anxious that he almost vomited blood, and complained again and again that Song Jiangong should have left manpower on the river beach to monitor the cliffs on both sides to prevent the brute soldiers.

Wang Yuan hurriedly paced back and forth, and Gongsun Lan frowned and said, "Otherwise, I will step on the rope and rush over to kill someone." ”

Wang Yuan waved his hand and said: "Absolutely not, I believe you can step on the rope to pass, but you are the only one who has the ability." And when you are close to the opposite shore, you must be the target of the opponent's poisonous arrows, and it is not easy to dodge the attack of poisonous arrows on the rope, and once you are shot one, you will be helpless. I'd rather have all the ropes cut off by them than let you go on an adventure. ”

Gongsun Lan frowned and said, "Can't you watch them cut off all the ropes?" In that case, it would be a waste of all the work that had been made. If you can't build the ropeway as soon as possible, but are delayed, then more than 10,000 soldiers and horses will have to be annihilated? ”

Wang Yuan stared at the small black dots on the opposite cliff, they had already begun to attack the Tang soldiers above the cliff who were unaware, and the corpses of the Tang army fell off the cliff one by one, making Wang Yuan extremely anxious.

"It's a pity that the distance between the two cliffs is nearly a hundred feet, too far for the crossbow arrows to reach, otherwise they would have been shot and killed." Li Mi stomped his feet.

Wang Yuan's eyes lit up, and he shouted: "Hurry up and push those two Fuyuan ballista carts, hurry!" ”

Li Mi was shocked and said, "Fuyuan crossbow car? When are we going to have this thing? ”

Wang Yuan waved his hand and said, "Go back and explain, go and drag it over." ”

The Fuyuan crossbow is a kind of bed crossbow, as the name suggests, because it can be extremely long, with a range of up to 300 paces, according to the current unit of length measurement, it is a long-distance bed crossbow with a range of more than 400 meters. Because of the need for strong bowstrings and bow body materials, the cost is extremely expensive. In addition, because of the long-range effect, although the arrows were made of pure iron, they were very thin and long, and the lethality was insufficient, so this kind of bow and crossbow was abolished for a long time.

This time, in order to crusade against the turnaround battle of Nanzhaoguo, Wang Yuan found two of these things in the treasury of the military department before leaving Beijing, and specially told Yang Guozhong to transport them with the weapons and materials. When they were resting in Wangzhou, these two Fuyuan crossbows arrived in Wangzhou after thousands of mountains and rivers. Wang Yuan originally wanted to study this weapon and give it some appropriate modifications so that it could play a greater role, so he didn't take it too seriously, and finally remembered these two things at this moment.

The two Fuyuan crossbows were quickly transported to the cliff, and by this time, the barbarians on the opposite side had already cut nearly half of the bridge cables. Thankfully, these ropes were not easy to break, as thick as a child's arm, and were made of hundreds of thin ropes twisted into twisted shapes, which were both tough and dense, and the brutes had to cut them with daggers for a while to break one of them. Otherwise, with such a delay, I am afraid it will be too late.

"Open the strings, load the crossbow arrows." Wang Yuan shouted.

A dozen soldiers began to shake the winch behind them, slowly pulling away the bowstring, which was as thick as a thumb and made of unknown material. The entire Fuyuan crossbow made of red sandalwood creaked, and the entire skeleton seemed to be unable to withstand the pull of the bowstring. The patent leather on it began to crack and fall. Wang Yuan's heartstrings were also tight, this thing was too old, as if it could fall apart at any time.

Finally, the bowstring reached its end and became stuck in the spring. Wang Yuan blew the dust in the arrow trough, put a heavy iron arrow rusty two feet long in the arrow trough, bent down, and with the assistance of several soldiers, aimed the Fu Yuan crossbow at a few small black spots on the opposite cliff wall. It is impossible to aim specifically at a person at such a distance.

Wang Yuan held his breath, grabbed the trigger on the side with his hand, roared, and forcefully pulled the trigger, the bowstring made a low and reckless 'vain' sound, the heavy bed crossbow seemed to jump a little, and the iron arrow flew straight out with a sharp whistle that broke through the air, instantly turning into a small black dot.

The iron arrow flew nearly a hundred feet to the opposite cliff and struck a jagged boulder above the three brutes. I heard a loud 'boom', rubble flew and smoke billowed out. The rock wall was shot with iron arrows, and countless stones cracked. The stones as big as a bucket and as small as a fist rolled down, and the three brutes below were suddenly hit by the falling stones, and they fell several feet high on the cliff wall and fell on the rocks of the river beach below.

The people on the north shore rejoiced, and although this thing was mediocre, it was obviously effective to hit the rock wall and attack the enemy soldiers with rocks.

"Hahaha, General Li, you can launch the other one, aim at the cliff wall above the rope, and shoot the rock wall will work." Wang Yuan laughed and ordered the soldiers to twist the bowstring again. Li Mi also ordered a group of soldiers to set up another Fuyuan crossbow and start shooting at the opposite rock wall.

"Boom, boom!" Several arrows were fired at the rock wall above the rope, and suddenly smoke and dust billowed on the opposite rock wall as if there had been an avalanche. In the smoke and dust, dozens of barbarians were smashed off the rock wall by the rocks, fell to the river beach and died, only one or two lucky ones were agile and moved several feet to escape from the range of the falling rocks.

"Shoot at the man in black on the right, the man is pointing fingers from beginning to end, it must be the leader of the barbarians."

Wang Yuan laughed and moved the bed crossbow with everyone, adjusted the angle, aimed the arrow at the black-clothed man who was pointing fingers, pulled the trigger, and the iron arrow roared out.
