These nobles are strange, behind the three-zhang high city wall, why are they densely packed with trebuchets? There are five soldiers standing next to each trebuchet, one officer-like guy in command, two in operation and adjusting the trebuchet, and two in the back burning charcoal. And no one cares? Besides, you are defending the city and not besieging it, what are you doing with so many trebuchets? Throwing stones is not as lethal to cavalry as bows and arrows!

Look at the city wall again, they are even more strange, when they entered the city, they didn't pay attention, only felt that the city wall of the small city here is high, and now they found that these city walls are not made of stone, they are all green bricks, and the gaps in the green bricks are not glutinous rice sticky, it is a gray thing, it is said to be called cement. Moreover, the city gate and the drawbridge over the moat outside the city gate are made of iron, not yet bronze, all pure iron! How much does this cost?

Happy Horse Slope is the weirdest.

The horse slope of the city wall, which is a must for the city wall of every city, is a huge slope, which is also used for war horses and the city wall and the transportation of thunder stones and rolling logs. The city of Mayi has done a more thorough job in this regard, the outer side of the city wall is steep and straight, and the inner side is full of slopes, stretching out as long as ten zhang before reaching the ground, and the slope is not large. How much land is wasted in the city? How much work is this? How did Lu Chen repair such a complete new city wall in just half a year? If they knew that Lu Chen had been repaired within two months of the cement and brick factories starting production, their eyes would have fallen to the ground.

When they arrived in the city, their legs were weak, and everyone wondered, why are there so few crossbows and arrows in the bed? The female wall is mostly occupied by some large iron pipes with black holes. What is this? Also, so many soldiers were under the walls. On the contrary, it looks empty, is it because he is afraid of the cavalry of the Xianbei cavalry? Don't dare to go to town?

Fortunately, at this time, the Xianbei Plundering Array had just passed, and there were no arrows flying around, so the nobles of the family hurriedly entered the city tower, and then felt a lot more relieved. Because this castle tower is also three zhang high, it is made of blue brick and cement, which is very different from ordinary wooden castle towers, and there are holes the size of bowls on all sides, so you can see the outside. Of course, they didn't know that this was designed by Lu Chen in imitation of the bunker of later generations. The main castle tower is the largest. On other city walls, there is a miniature version of the small city tower every thirty zhang, which is mainly used to store materials and ordnance, as well as the rescue of wounded soldiers.

It is expected that the bow and arrow of the Xianbei people are not so accurate. Shoot straight into the hole. Inside the cement house. There is also a huge coal stove. Stop warming. Especially seeing that Lu Chen's intention was to show force, rather than taking them hostage, the family was a little calmer.

Through the hole in the front of the castle tower. The families saw a large field of Xianbei cavalry outside the city, their leather armor glowing with a dark red glow in the setting sun. Many people's teeth are chattering, and many people have seen war, but few people have seen so many cavalry. Moreover, everyone knows that even the most elite Xiliang Iron Cavalry of the Han Dynasty is inferior to the Xianbei Cavalry, which is full of soldiers, so they will naturally feel afraid.

Xu is Xianbei scouts found that a large group of nobles in Chinese costumes were kicking the city, and a group of cavalry, about five or six hundred, galloped out of the Xianbei iron cavalry, and began to plunder the city again.

"In an hour, the war will end. Everyone, hurry up and watch, there will be no such shop after this village. I have a dozen or so clairvoyances here, which can pull the scene from miles away in front of you, and you can take it and look at it carefully, there are not many of them, please take turns to use them. ”

Lu Chen, who had not spoken, spoke at this time, holding some wooden sticks in his hands. The rod was more than a foot long, hollow, and was inlaid with round crystal pieces at both ends, and was tied by a narrow belt.

Clairvoyance? What's that? Something from myths and legends? The families were puzzled, apparently not believing that they could pull a scene miles away in front of them, and that there was no such thing in the world.

Lu Chen handed the three to Lu Bu, Zhang Yang, and Chen Gong, and gave another to the curious old man Pang Degong, and hung one himself. Seeing Sima Yi's curiosity again, Lu Chen smiled indifferently and gave him the rest and asked him to distribute it.

Sima Yi is a smart person, although Lu Chen has not paid attention to him since he came to Yanmen, and occasionally makes jokes, but he knows that Lu Chen, who is extremely gentle or hypocritical to others, treats him like this, obviously to put him in a correct position, that is to say, Lu Chen knew that he wanted to come to Yanmen to do things, and he agreed. Therefore, Sima Yi was not polite, he detained one first, and gave the rest to the people nearby.

"Wow! It's scared to death, that Xianbei man's head is bigger than a millstone! The guy jumped back in fright, stepping on the person behind him.

"It's amazing! You can really see the scene miles away! Another one was amazed.

"Look at the Xianbei people with arrows, ah......" This thing was so frightened that he squatted on the ground with his head in his hands, and he saw the Xianbei people shoot arrows with their "eyelids lowered", which frightened the little heart.

"Artifact! Artifact! This thing should only be in the sky, ah, the arrow is coming...... "An old man blew his hair and hit his head against the wall, even so, he carefully protected his clairvoyance, for fear that he would not be able to pay for it.

The other guys who got clairvoyance first were similar, startled and not to mention, and they were very timid.

Lu Chen despises these turtles! He also called himself a nobleman! I've never seen the world. He also took the telescope and looked out of the observation hole, not to mention, these glass pieces that were originally used as test objects, although there were many impurities and a thick green color, but after grinding, they could barely be used. At least, it's no problem to fool these big families and the princes of the Central Plains into placing orders. The key problem is that these telescopes are all hand-ground and hand-made, not a uniform system, and even magnification is far from the same. Fortunately, others don't pay much attention to this issue. Lu Chen didn't mind, in short, this thing was difficult to make, it required the most exquisite craftsmen and techniques, and he didn't plan to sell more! The more expensive, the better! Lao Tzu's play is that things are scarce and expensive, looking at the posture of those dirt buns, this thing can't be cheap.

The Xianbei people really rode well, galloping along the root of the city wall, and the knights did not control the reins, but relied on their legs to control the direction of the horse's belly. There are no stirrups, these guys are clamped tightly enough! Lu Chen muttered in his heart, and saw the Xianbei people start shooting arrows. Shooting targets in the city under the city, the Xianbei people use projectiles, which are easy to shoot people, but the bows and arrows thrown are soft bows, and the strength is not enough, as long as they don't penetrate the eyes and heads, at best, they will hurt people, and it is difficult to kill.

The capital guards in the city, that is, Zhang Gu's Hanoi soldiers, are not ambiguous, holding wooden shields against them, they are not afraid, and they are still shooting downward, but the archery skills of these guys are obviously inferior to Xianbei people, which is almost equivalent to wasting arrows. However, it doesn't matter, anyway, the Xianbei people are about the same, come and go, everyone picks up the arrows, and the ordnance is not a loss, and the fight is quite lively, which is good.

"Yikes! Look at the woods behind the cavalry! Xianbei people are building ladders! ”

Suddenly, a guy raised his glasses and howled, which alarmed everyone, and everyone looked behind them. People who don't have binoculars can't see clearly, and they are even more anxious to urge the people in front to hurry up and read them to the people behind. There were also people who advised Lu Bu to hurry up and send out cavalry to attack and disturb, and not to ask the Xianbei people to build ladders and trebuchets. (To be continued......)
