The official road outside the Imperial Capital may be the best official road built in the entire Han Empire, even if the rain is pouring in the sky, there is not much water on the official road outside the Imperial City, and there is no mud, and the rain falling from the sky washes the road surface on the official road cleanly, and the rainwater on the road naturally flows into the ditches on both sides of the official road......

When Yan Liqiang went to the Forbidden City in his last life, he heard the tour guide of the Forbidden City say that many places in the Forbidden City are paved on the ground, and they are not slate but bricks fired by the brick kiln, commonly known as gold bricks, for the exclusive use of the Imperial Palace.

Under the washing and washing of the torrential rain, the bricks on the road revealed their original blue-gray appearance, which has a unique ancient meaning.

Yan Liqiang, who was wearing a poncho and holding an umbrella, walked on this official road, only a pair of boots on his feet were slightly stained with a little rain, stepping on this blue-gray ancient road, Yan Liqiang's mood had a different kind of ease of stepping on the rain, and he didn't feel half nervous about what he was about to do, even if what he did would bring him ruin after being exposed.

Looking at the road under his feet, Yan Liqiang was amazed by the skills of the craftsmen of the Han Empire, but the scene of firing this kind of road bricks came to mind, firing such a road brick more than two feet long and more than a foot thick is not an easy thing, I remember that the tour guide of the Forbidden City said that in order to burn out such a large floor tile, the temperature of the brick kiln that burns this kind of floor tile must be very high, so as to ensure that the middle of the burned floor tiles is not black and brittle, and the whole body must be the same color, every gold brick in the Forbidden City has the name of the fired brick kiln and the name of the craftsman in charge, any gold brick has a problem, it can be traced, and the head must be cut off, so no one dares to be carelessAt the same temperature, if the floor tiles are not fired, the clay and limestone are put into such a brick kiln to burn, and the burned is cement.

This is still modern cement, while the so-called ancient Roman cement is simpler, only need to have enough volcanic ash, and then burn the raw lime, plus water, sand and stone, the most primitive concrete is constantly produced.

In ancient China, the kiln firing technique was separated from the firing of cement by only a layer of window paper.

Similarly, the Han Empire does not seem to have a convenient and quick building material like cement.

Roman cement created the Roman Empire, and I don't know what kind of Han Empire can be created by making cement in this era.

Yan Liqiang's thoughts were flying, and his gods flew out of the sky......

"Woo ......" A carriage ran over from the rain and fog, and when it passed by Yan Liqiang, it stopped suddenly, and the coachman wearing a hat and a cloak shouted to Yan Liqiang, "Little brother, it's raining heavily on this road, if you don't dislike it, I'll give you a ......."

"Thank you uncle, I like to take a walk, and I'm going to the West Gate, it's not far, I'll be there soon!"

"Hahaha, that's okay, little brother, you can walk slowly if you have good foot strength, but the thunder has been heavy in the past two days, but don't hide from the rain under the trees, last year there were several trees next to this official road that were hit by thunder!" The coachman laughed, and reminded Yan Liqiang, then shook the reins, and drove the car into the rain.

This is already the third enthusiastic person Yan Liqiang met along the way who saw him walking in the rain and wanted to pick him up for a while.

Yan Liqiang didn't get into the car, but his heart had already been warmed by the small kindness of these few strangers in a row.

Looking at the carriage that disappeared in the rain, the belief and determination in Yan Liqiang's heart became more and more hard as iron at this moment - when the natural disaster came a few years later, he must let these thousands of people leave the imperial capital and escape, and he must also live until that time, all those who stand in the way of his goal will kill and never be merciless......

......

When Yan Liqiang came to the west gate of the Imperial Capital City, because the time was close to evening, the sky was darker, and the rain in the sky was unexpectedly much lighter.

Yan Liqiang still entered the imperial capital from Xihua Gate, and just entered the city, just walking less than fifty meters away, Yan Liqiang felt that he was being targeted.

Staring at him was a man dressed in gray, in his thirties, with an ordinary face, which he had not seen before.

That person was hiding from the rain on the side of the street at the gate of Xihua just now, his eyes scanned the faces of the people entering the city, as soon as Yan Liqiang entered the city, that person's eyes turned around Yan Liqiang's face twice, and then mixed next to several carriages and horses entering the city, and followed Yan Liqiang quietly.

The first time Yan Liqiang was stared at here in Xihuamen was because of Fang Beidou, and this time the person who stared at him obviously had nothing to do with Fang Beidou.

However, Yan Liqiang was not surprised, because this was already in his expectation, and even confirmed his guess, his current news in Luyuan is not a secret, and those who are interested only need to check it to know, and if you come to the imperial capital from Luyuan, Xihuamen is the closest, so as long as you put a person on the side of Xihuamen, waiting for the rabbit, if he wants to come out of Luyuan to the imperial capital, he will be targeted as soon as he enters the city gate.

The purpose of staring at people is to grasp the whereabouts and news of that person, this is a prelude to dealing with a person, as for who is going to deal with himself, Yan Liqiang thinks about it with his knees, and now in the entire imperial capital, there are people who can have a holiday with such an inconspicuous "little person" as him, and they like to use despicable means, isn't it Xu Lang's people......

It seems that the decision to strike first was the right one.

Yan Liqiang didn't look back, he was still walking with an umbrella, and he didn't deliberately want to ask the person who was staring behind him, but the smile on his face was inexplicably a little colder.

......

When I came to the outside of the sky, the rain in the sky stopped, and a long string of lanterns had already been hung up outside the restaurant, and the gorgeous carriages and horses stopped outside the restaurant.

Yan Liqiang arrived half an hour earlier than the scheduled time, which was considered polite, and Lu Peien, who contacted the dinner, came earlier, and a steward beside Lu Peien was already waiting at the door of the restaurant.

As soon as Yan Liqiang walked over, the steward of the Lu family immediately lit up his eyes, and hurriedly greeted him, "...... Gongzi Yan"

"Well, is Brother Lu here?" Yan Liqiang said as he handed the umbrella and poncho in his hand to the two maids in the restaurant.

"The sixth master is already in the room, if I tell Yan Gongzi to come, I will take Yan Gongzi up......"

"Okay, let's go......"

When entering the restaurant, Yan Liqiang saw the man in Tsing Yi staring at him out of the corner of his eye, standing on the street more than 30 meters away from the restaurant, staring at him and entering the restaurant......

After Yan Liqiang completely entered the Outer Heavens, the man in Tsing Yi walked towards the Outer Heaven Restaurant, but as soon as he wanted to enter, he was stopped by several greetings standing at the door of the restaurant.

"May I ask the guest officer to book the room in our outer world?" The greeting of the outer heaven had a professional and polite smile on his face, but the critical and sharp gaze looked at the man in Tsing Yi from head to toe in an instant, and his eyes unconsciously revealed a trace of disgust.

"I have a friend who just went in, and I'm going in to find someone......," said the man in Tsing Yi.

"I'm sorry, we are all guests who have booked a room in advance, if the guest officer has a friend inside, the guest officer tells me the room where your friend is, I will take the guest officer in, if the guest officer you don't know where your friend is, then please ask the guest officer to wait outside the door......"

"I have something urgent, can I be accommodating...... Tsing Yi man smiled all over his face, nodded his head.

"Then tell me your friend's name, approximate appearance and age, and what clothes he is wearing, and I'll go in and ask for you!"

The man in Tsing Yi suddenly opened his mouth and stammered, "This ...... This ......"

The man in Tsing Yi wanted to say something, but the greeter gave him a look, and the two restaurant guards next to him, who were strong and not easy to mess with at first glance, had already walked over, staring at him with burning eyes, and one of them clenched his fists so much.

In the end, the people in Tsing Yi had no choice but to leave, but they didn't go far, but waited on the side of the road dozens of meters away from the gate of Tianwai Tianmen......
