The Grand Master was tired, didn’t he sleep well last night?”

On the carriage driving smoothly, Emperor Shin-Emperor saw Chen Xu's slightly blue eyes and absent-minded look, and couldn't help but ask with concern.

"Your Majesty forgives your crime, you are anxious in spring. I did not sleep well last night!"

Chen Xu quickly explained that in fact, he was still continuing his thoughts in his heart at this time.

Although the ten young masters accompanied him, including Hu Hai, they were obviously completely different from the record of the last tour of the First Emperor in history.

In other words, this tour has become completely different from history since the beginning.

Then it seems that your own planning and plans need to be changed, otherwise you will not be able to keep up with the changes in history.

"Well, now it's getting summer, and it's really sleepy and dry. I've been sleeping very lightly in recent days. I woke up after hearing the wind and rain, and then I've been unable to fall asleep again!"

The First Emperor had no idea that Chen Xu was still in a sloppy position at this time, and nodded with a stern heart. Of course, he didn't know the heroic achievements of Chen Taishi Chen in the Qin Dynasty last night and thought that Chen Xu had really not slept well like him.

Faced with chatting with the emperor, Chen Xu could only temporarily put away his confusing thoughts and decided to make some preparations on the way. When he arrived at Wuzhong, he gave a smile and bowed, "Your Majesty is not worried. This is a common symptom in spring. You can drink some decoctions to relieve fire and calm the spirit. You can also do some exercise on weekdays. You can also meditate and breathe before going to bed to practice the Taoist mental method left by me last time. Perhaps it will have some effect!"

"The Grand Master is right. There are so many things happening recently. I have indeed not been meditating and practicing well for some days. It seems that I still have to persevere... Hey, what is the digging of such a deep trench near Chang'an Palace?"

The carriage and horses drove to the near Chang'an Palace. The First Emperor looked at a huge trench of centipedes that was digging outside the car window and asked in surprise.

"Your Majesty, this is called a sewer!" Chen Xu pushed open the window and said with a smile.

"What's the use of the sewer?" Emperor Shi was as humble and studious as ever.

"The sewer is a pipe that discharges sewage and rainwater. It has similar functions to the drainage ditch in Xianyang City, but it has a greater effect. It can gather rainwater, sewage, manure, etc. inside the entire city into this big ditch..."

"Xianyang is now too large, with various sewages increasing, and drainage facilities are gradually aging, and many places are even blocked by sludge, causing water accumulation and even soaking in many places in the city every time it rainstorms, causing inconvenience in traffic, and it is also easy to breed mosquitoes and rats. In fact, Xianyang is now overwhelmed, which is also the reason why I asked His Majesty to move the capital."

"The construction minister of the Xindu City, the Academy of Sciences, the Ministry of Works and other offices have conducted many arguments and consultations, and decided to dig a large enough culvert underground first, build a huge sewage pipe network with bricks and stone cement, and connect the whole city together with trenches and cement pipes. Then build various houses and palace facilities on it. After the construction is completed, water inlet and drainage pipes will be laid and installed according to unified standards. With these infrastructures, whether it is the court office or the people's home, you can install sanitary ware equipment such as tap water and squat toilets, and there is no need to arrange for people to pick up manure and transport it every day..."

"Well. This planning is indeed convenient. But if every household needs to access tap water, wouldn't it be necessary to build countless water towers? The imperial palace office is still good, and ordinary families may not be able to afford it!" The First Emperor understood and added many doubts.

"Haha, Your Majesty has no worries. This time I plan to plan to build a huge reservoir in the upper reaches of the Ba River, and then use water pipes to introduce water into the new city, so that every household can get tap water. Of course, because the construction price is expensive, it will take some money to install the civilian home at that time!"

"It is not difficult to build a reservoir in the upper reaches of the Ba River, but isn't it easier to use ditches? How do you need to use water pipes?"

"There are two benefits of using water pipes. One is to ensure the water quality is clean, and the other is that the sealed water pipes can ensure sufficient water pressure and put the tap water onto a building with several stories high..."

"Can the water pipes still send water to a high place?" Emperor Shi interrupted Chen Xu in surprise.

"Indeed, this is a common physical phenomenon. Students from the Academy of Water Pressure Principles and the School of Engineering are very clear. A few years ago, I conducted a hemisphere test in Cuju Square. Your Majesty should have heard that not only water, but also air that seems empty also has huge pressure. Once the pressure inside and outside the object is different, a pressure loss phenomenon will occur. With this pressure loss principle, we can send tap water to a high building..."

After Chen Xu's explanation, the First Emperor heard it as if he was falling into clouds. Chen Xu could only stop the popularization of physical science and said with a smile: "Your Majesty, the entire tap water project is very complicated and has strict requirements. The premise is to ensure that the water level of the reservoir is high enough, at least dozens of feet higher than the Xindu City. Secondly, the water supply pipeline network must be strictly sealed and not leaking. Although it has not been solved yet, I think it can be laid out in advance. Although the sewer seems to be huge and has no effect at the moment, it will inevitably see its benefits in the future. The future of tap water is inevitable, and it is also very necessary to plan ahead now!"

"The Grand Tutor is far-sighted. If you plan things first, there will be less trouble later. I am looking forward to the grand occasion of tap water in every household in the city..." Emperor Shi's first emperor looked at the construction site outside with hope and sighed.

"As long as the Qin Dynasty is stable, life will only get better and better in the future. I am now organizing the Academy of Sciences to develop a new steam engine, powered by coal stone and water. If it is successfully developed, it can create a steam locomotive with infinite strength, hundreds of feet long and thousands of people can ride at a time. If Your Majesty goes on a patrol again, you won't have to ride a carriage..."

"What? There is such a magical vehicle?" Emperor Shin-Emperor was so surprised that he almost bit off his tongue.

"Yes, the principle of the steam engine is not complicated. After several years of research, the Academy of Sciences has achieved some results. However, if it really needs to be put into application, the court still needs to invest huge manpower and material resources. This kind of car needs to run along fixed rails, and both vehicles and tracks have huge investments!" Chen Xu explained with a smile.

"The Grand Tutor does not need to worry. Last time, Fan offered me steel and cement and other factories and mines, there was no shortage of building materials. Although manpower was short, it was only a temporary worry. My mausoleum was about to be completed, and more than 200,000 prisoners were available. As long as the Grand Tutor could make this steam locomotive, I will definitely support the construction of new railway tracks. I really don't know what style this steam locomotive is. Every time I chat with the Grand Tutor, I always feel that the world is wide and novel, and I know it as shallow as a frog in the well..."

The First Emperor leaned on the back of the chair with excitement and sighed.

"Why should Your Majesty be tainted by yourself? You have specialized in your skills. Your Majesty is the king of a country, and you can control all the people in the world. Making tools is the business of craftsmen. Why should Your Majesty know that controlling people is the best and controlling things is the best? What's more, the three volumes of heavenly books are all extremely magical. I was young and ignorant at that time, and I didn't remember much. There were many magical things that flew to the sky and escape to the earth. I was afraid that I would not be able to do it in this life!" Chen Xu also sighed and sighed.

I only regretted that I had little time to use the books, but unfortunately, most of the basic physics, chemistry, and mathematics knowledge in high school have been returned to the physical education teacher.

"The manpower is always exhausted. It is already an opportunity for the Grand Master to obtain three volumes of heavenly books. Now I can make so many incredible things that make me and ordinary people just marvel and worship. How can I belittle myself? In the future, the Great Qin Dynasty will have ships, giant boats, steam locomotives on land, and bicycles, which are exquisite and convenient. Such an unprecedented prosperous era has never been seen in China. If it weren't for the Grand Master, I would probably not have imagined these whimsical things in this life. On this tour, I can't wait to see the magnificent river ports and harbor docks, and to see the giant ships that sail far away from the sea as if walking on the plains!"

"As Your Majesty wished, you will definitely be able to see the grand occasion this time!" Chen Xu bowed and smiled.

...

The First Emperor left the capital and toured his territory for the sixth time.

And the southeast coast is no longer the scene when Chen Xu visited the smooth road plan last year.

Last September, Gongsun Beiyan, who gave up Yingzhou, and a group of supporters led more than ten new and old sea boats of all sizes to prepare food and drink for two years, and thousands of people rode the wind and waves across the ocean.

In October, I passed by Panyu Harbour, Guangdong County, and stayed for a short day to replenish freshwater. After continuing to sail, I quickly arrived at the Leizhou Peninsula and saw Hainan Island not far from the sea.

They thought that was what Chen Xu called Australia, but they excitedly rushed to the dock and found out that this was just a territory of the Yue people, and a group of Nanyue people who claimed to be Li people lived.

Because Hainan Island is less than fifty miles away from the mainland, islanders who are good at boating still come and go from time to time with the Yue tribes on the mainland. It takes only half a day to row across the strait. Although it is not particularly convenient, it is not a wild place isolated from the world.

What made Gongsun Beiyan and others most depressed was that the people here also told them that just over 20 days ago, two luxury ships had also been here, and exchanged many dried fruits and dried fruits with ceramic glass daggers and other items, which made a large number of Li people gathered on this simple dock closest to the mainland, and they made a large bag of dried mangoes and dried longans here every day to look forward to making a fortune.

Those two ships must be Qinghe Hou.

Because they met in Langya just twenty days ago.

Some people who accompanied him persuaded Gongsun Beiyan to occupy Hainan Island to develop.

This island is not only big, but also warm all year round as spring. All kinds of flowers, fruits and food utensils are extremely rich. As long as you manage it for a few years, it will inevitably become a very prosperous island. Moreover, it is very close to Daqin and convenient to get around.

However, these suggestions were quickly rejected by Gongsun Beiyan and ordered the fleet to continue sailing across the Qiongzhou Strait to sail towards the South China Sea.

It’s not that she doesn’t want to stay, but that she doesn’t dare.

The reason why they dare not be that this place is too close to the Qin Dynasty. If they founded the country here, they would be surrounded by the Qin Haizhi fleet in less than a month and would be bombarded into pieces.
