There is almost no vegetation on the mountain ridge pass where the city is located, in stark contrast to the lush greenery of the valley and surrounding peaks. This is clearly not a natural occurrence, but can be done. The hillside leading to the pass was manually cleared of all the turf, dirt, and trees.

The lights inside and outside the more than a dozen beacon castles shone on the sound of the large stone slopes, reflecting a faint halo, smooth like a mirror. The slope is so steep that there are no steps, and the whole thing is a bare stone slide.

Wang Yuan and Gongsun Lan didn't dare to get too close, because there were figures shaking around the several beacons in the middle of the stone slope, which were the sentry agents of the Tubo people. No matter what angle you want to touch from below, you will inevitably be found. The location of those stone forts is also extremely tricky, and there must be crossbowmen stationed in them, and if they are discovered, they will inevitably suffer from the baptism of bows and crossbows.

The two of them hid behind a bush at the bottom of the slope and carefully observed the pattern, Wang Yuan didn't say a word, his brows furrowed tightly.

"Erlang, the location of Motuo City is really precipitous, and this city is not easy to attack." Gongsun Lan whispered in Wang Yuan's ear.

Wang Yuan nodded and said, "Of course, otherwise, why is this valley so flat and comfortable, but the Tubo people don't build a city in the valley?" That is because the terrain of Shanliang Pass is steep, and the pass used as a defense is the best choice. Therefore, no matter how beautiful the scenery in the valley is, they will not build a city in the valley. ”

Gongsun Lan nodded and said: "This hillside is as smooth as a mirror, it is difficult to climb in ordinary times, and it is probably even more difficult for the army to attack the city." ”

Wang Yuan said: "It's not just more difficult, it's just difficult to plug in the wings." This rocky slope is obviously man-made, and it is deliberately steep and smooth, so that we cannot attack it. I dare to say that this must have been done in the past ten days, and the Tubo people have spent a lot of effort to deal with us, and they must have filled in the steps on the original hillside and removed all the earth, rocks, grass and trees. ”

Gongsun Lan said softly: "Do you have a way to deal with it?" ”

Wang Yuan slowly shook his head and said, "Not for the time being." Siege engines are absolutely impossible. The blockade of several beacons on the hillside was enough to inflict too many casualties on my army. Moreover, the location of these beacons is also very tricky, just hundreds of steps down the slope, and under the cover of the mountain rocks, they are shaped like dark castles. Whether it is a Shenwei cannon or a Fuyuan crossbow, it can't be fired on a stone slope, and the distance is not enough to fire it when it is fired at the bottom of the slope but the line of sight is blocked, so this is a ** annoyance. ”

Gongsun Lan said softly: "What I said is that the scale of these dozen beacons is not small, each of them is like a stone castle, and there must be a lot of crossbowmen in it. It only takes a few hundred crossbowmen to block the entire slope. These are just the first ones in front of you, and there are probably a few guards behind you. By the time the army rushed to the foot of the city of Metuo on the mountain beam, thousands of people had already been shot. ”

Wang Yuan shook his head and said, "You can't attack hard, otherwise you will be defeated." What if you pay a huge price to reach the city of Metuo? If the siege equipment can't go up, it still has to be attacked with human lives. This is not the siege method I was hoping for. ”

Gongsun Lan comforted softly: "Don't be in a hurry first, and then see if there is a way up the mountain that can avoid this slope." On second thought, there may be a way. ”

Wang Yuan nodded, and after the two of them hid in the bushes and trees, they looked towards the north side of the uphill entrance. However, they were soon disappointed, and on the north side of the rocky slope was a steep and straight mountain wall, black as if a great barrier was erected in front of them, and further north, walking along the edge of the valley for a while, they found that the cliffs were all high, and there was no way up at all. Wang Yuan and Gongsun Lan can certainly climb up with all their might, but what is the use of that? It is not good for siege.

The two turned around and walked towards the south side, the same cliff was towering, after walking out of the land of Lixu, but listening to the faint sound of flowing water like thunder, the two walked dozens of steps to the south, and found that there was no road ahead, and a black hole canyon lay in front of them.

Even though it was dark, you could still see the outline of the Grand Canyon by starlight in the dark night. It came from the west, and at the valley where the two men stood, it turned to the south, like a thunderbolt between heaven and earth, splitting the earth into a great crack, and dividing the high valley into two halves. The scenery on the opposite shore is blurred, and the two cliffs of the canyon are at least a few miles away. Below the canyon, an unknown cold wind rushed from the bottom to the top, blowing the clothes of the two people standing on the edge of the cliff fluttering.

Wang Yuan and Gongsun Lan were surprised to stand on the edge of the cliff and were silent, the magic of nature was enough to make people jaw-dropping, standing next to such a big canyon, people seemed so small and powerless.

"There's no way, how can this be good? There was no way up except for the rocky slope. Gongsun Lan frowned.

Wang Yuan sighed and turned his head to look around, squinting his eyes and trying to distinguish the surrounding scenery, and then he suddenly walked towards the mountain peak and the canyon, and suddenly disappeared.

Gongsun Lan Shangzi looked down the canyon, turned around and disappeared Wang Yuan, he was shocked, and called out anxiously in a low voice: "Erlang, where have you been?" ”

"I'm here." Wang Yuan's voice came from the mountain wall on the west side, accompanied by the sound of Si Xi Suo stirring the grass and trees.

Gongsun Lan hurriedly followed the sound, but saw Wang Yuan standing in a waist-deep pile of bushes and grass, which turned out to be between the edge of the canyon and the cliff.

"I wonder why there are so many plants and trees growing here, there is really a small ledge here. Cousin, be careful, the ledge is only as wide as one foot, but it is not very stable. Don't move, I'll go and see if there is a slope up the hill in front of this ledge. Wang Yuan spoke in a low voice as he walked deeper along the ledge.

Gongsun Lan would let him go on an adventure alone, so he hurriedly followed him into the ledge. As soon as I stood up, I felt that this place was cramped, the small ledge only allowed two feet to stand, one side was a high mountain cliff, and on the other side was a deep valley with a bottomless cold wind, even Gongsun Lan felt very uncomfortable.

"Erlang, don't take any chances, it's too dangerous here." Gongsun Lan shouted.

Wang Yuan smiled: "With my cousin's protection, what is the danger?" ”

Gongsun Lan said angrily: "Falling into the canyon is not a joke. ”

Wang Yuan laughed and said, "If I fall, what will happen to you, cousin?" ”

Gongsun Lan sighed, was silent for a moment, and said, "It's a big deal to jump down with you." ”

Wang Yuan's laughter came from the darkness ahead: "Is my cousin going to be martyred?" That's not necessary. If I fall, you will live your life as you should. Martyrdom is stupid. ”

Wang Yuan's laughter continued, and suddenly there was a sigh, Gongsun Lan was startled, and moved dozens of steps to Wang Yuan's side, but saw that Wang Yuan's body was shaking, and he seemed to have an unstable footing. Gongsun Lan grabbed Wang Yuan's arm with his hand, clasped the gap in the cliff with the other hand, stabilized Wang Yuan's body with force, and said in a low voice: "Don't laugh, concentrate, calm your feet, and move steadily sideways towards the cliff, otherwise the bow and arrow behind you will occupy the space." And he cut the grass and trees with his hands, so that he would not stumble. ”

Wang Yuan smiled and said, "Is the master here to teach the apprentice again?" ”

ridiculed in his mouth, but he didn't dare to be vague in his actions, acting in accordance with the tips of Gongsun Lanjiao, and steadily and steadily moving forward along the narrow stone beam. The stone beams are about 100 steps long, and then they return to the cliff and become part of the canyon cliff. Wang Yuan stood at the end of the end, clasping the crack in the cliff with both hands, leaning back and looking forward, and suddenly he found that the slope of the cliff not far away seemed to have slowed down a lot, and it was not as straight as it was in front of him.

"Cousin, there is a road ahead, but I am afraid it will be difficult to reach. See, there's a protruding rock, just a dozen paces away. Behind the rock, there seemed to be a slope leading to the top of the mountain. ”

Gongsun Lan frowned and said, "So what? Are you going to climb up the mountain from here with your army? I'm afraid that if I don't have to fight, tens of thousands of people will fall to death. ”

Wang Yuan smiled: "It's all here, why don't you go and take a look." If you can reach the top of the mountain, you can at least take a condescending look at the situation of the city on the mountain beam. ”

Gongsun Lan sighed and said, "It's up to you." But how? Your hook seems to have no focus. ”

Wang Yuan said: "You don't need to shoot the hook, I'll pull you and throw you over." When you pass, throw the rope and come and pick me up. ”

Gongsun Lan had no choice but to accompany Wang Yuan to mess around. But seeing that Wang Yuan was clasping the crack on the cliff with one hand, and the other hand reached over to hold Gongsun Lan's small hand, after the two of them were ready at the same time, Wang Yuan used his hand hard, exhaled and made a sound, and waved Gongsun Lan's body hard. Gongsun Lan flew over a distance of more than a dozen like a light swallow, turned in the air, and landed lightly on the boulder in front of him.

Wang Yuan applauded, Gongsun Lan took off the rope behind his back, made a rope ring and threw it over, impartially putting it on Wang Yuan's body. Wang Yuan sang in a low voice: "Girl of the horse, you are mighty and majestic......"

Before he could finish singing a single lyric, he felt a strong force coming from the other end of the rope, and his body flew up like a cloud, and when he landed, he was already on the rock.
