Liu Che took a deep breath and opened the document. While reading it, he was thinking about how to deal with Liu Tan when he came back.
Today, Liu Ju happened to be discussing state affairs with him. Seeing that Liu Che's aura kept changing, sometimes smiling and sometimes looking angry but not so angry, Liu Ju felt a little itchy - what on earth had his brother done?
After a while, Liu Che suddenly laughed and said, "Using copper as a mirror can correct one's attire, using people as a mirror can help one understand gains and losses, and using history as a mirror can help one understand the rise and fall of a country. Ju'er, what do you think of these words?"
Liu Ju didn't respond immediately after hearing this. Instead, he pondered over it, and finally said with great admiration, "To be able to say such thought-provoking words, this person must be a genius of the time. What new talent has your Majesty discovered?"
Liu Che laughed and said, "That's what Tan'er said."
Liu Ju: ?????
Liu Ju's expression was blank for a moment. He really couldn't connect the three sentences with his younger brother who was always trying new food.
Liu Che simply handed the information to Liu Chuan and said, "Take a look first."
Liu Ju stood up, took it with both hands and began to read it impatiently. At the same time, he was a little puzzled. According to the time, his brother should have started his journey back. Could it be that something happened on the way that made his father look both satisfied and dissatisfied?
However, as Liu Ju watched, he knew why Liu Che's expression was so strange. To be honest, Liu Che's expression had only changed slightly before. If Liu Ju did not know him very well, most people might not be able to see the ups and downs of his mood.
Liu Ju's ability to control his emotions was clearly not up to par, so his expression became extremely distorted. Even after reading Liu Tan's last three sentences, he couldn't help but look up and say, "Fifth brother...Fifth brother, are you going to fight back?"
Liu Che said coldly: "That's not the case. I can't imagine why he suddenly wants to build a city."
Liu Ju gasped: "Why didn't I know he was so angry before?"
Liu Che glanced at him and said, "You still don't understand him."
However, Liu Che saw through Liu Tan's true nature at first sight: he was round on the outside but square on the inside. He always said that Liu Tan was like Wei Qing in this respect.
Otherwise, Wei Qing's personality was a bit dull, which was basically different from Liu Tan's temperament. How could Liu Che think that he was similar to Wei Qing?
When Wei Qing returned to Chang'an, he was quiet and silent as if he was an ordinary person, but when he arrived on the battlefield, he was an invincible god of war. The difference between them was huge.
Liu Ju didn't think too much about it, but said worriedly, "He's really reckless. The conditions in the Western Regions are difficult and only suitable for raids. He himself knows that the supply line is a problem, and he still wants to build a city. How can they let him build a city comfortably? Father, quickly order my fifth brother to return."
Liu Che said without comment: "No rush."
He was not anxious, but Liu Ju was a little anxious: "Father, my fifth brother is young and does not know the immensity of heaven and earth. War is not a joke."
Liu Che chuckled. "Do you really think that little bastard wasn't prepared? If he was acting on impulse, he wouldn't have wanted to build a city. And didn't you see the place he chose? Not only can it target the Jie Kingdom, it can even monitor the Cheshi Kingdom. And it's right next to a river valley. With the terrain being convenient, even if they were attacked, they could use the river valley to quickly escape and wait for reinforcements. This isn't something you can do on impulse."
Liu Ju was stunned for a moment after hearing this. He lowered his head to look at the map, and suddenly he realized something: "Huh? Why does this map look different from the previous ones?"
Liu Che sighed, "That's something he's just come up with. He claims to have established a new way of drawing maps. It does make the images much clearer, but I wonder what that new sand table he's created actually looks like."
Liu Ju's expression became distorted again: "Is he really just going to see the bride off?"
Liu Che sneered and said, of course not. He was still on the way to send his bride off, instigating Danyang to attack Wusun!
This is because Liu Che saw that Danyang and Liu Tan had a good relationship, and that dealing with Wusun would not harm the Han Dynasty, so he did not intervene. Otherwise, he would have ordered Liu Tan to return immediately.
Liu Ju looked up at Liu Che and said, "Father, is there any expert around my fifth brother?"
Liu Che opened his mouth and asked, "Huo Guang, Jiang Chong, Li Buyan, Wei Buyi, which of these do you think is it?"
As for Li Guangli, Liu Che no longer wanted to mention him. How could he not know that Li Guangli was drunk by Liu Tan on the first day he arrived there?
He took another sip the next morning, and when he woke up he had a splitting headache. He went to the doctor to get some medicine, but the more he took it, the worse the headache got. In the end, he could only rest exhausted in the tent. This person was basically useless.
Liu Che was not without anger at Liu Tan's treatment of Li Guangli. After all, he was the one who sent him there. But when he thought about how Liu Tan had easily treated Li Guangli like this, he felt a little ashamed and wanted to let this guy fend for himself.
As soon as the names of these people were announced, Liu Ju fell silent. As for Huo Guang... let's not talk about him. If he had the ability, he would not have gone to the Western Regions only now. Not to mention Jiang Chong, he was just a villain.
Although Li Buyan and Wei Buyi were both born into military families, one was simple-minded and the other was taciturn, and neither of them seemed to have the talent.
So... this was really Liu Tan's decision?
Liu Ju hesitated and said, "Could it be that... my fifth brother has such talent?"
Liu Che suddenly sighed: "Let him go, I want to see what tricks he can come up with."
Liu Ju looked at Liu Che and understood why Liu Che sighed, because even if Liu Tan had such ability, this would probably be his only chance, and there would probably not be anything that would require him to go on a diplomatic mission to the Western Regions next time.
It is impossible for the princes to lead the troops. The princes of the Liu family... are more restless than each other. Now Liu Che doesn't even dare to let the princes handle the affairs of the vassal states. He directly appoints the prime minister. The princes are basically in a sidelined state. How can he be allowed to lead the troops?
Thinking of this, Liu Ju suddenly felt a little depressed. He even thought that it would be great if he could keep Liu Tan in Chang'an. If he wanted to go out, he could let him go, and he could also give him the taxes from the fiefdom. In this way, it would be okay for him to lead the troops. After all, he had no foundation and when he came back, he would be under his nose. What was there to be suspicious about?
But Liu Ju didn't say it in the end, he just nodded silently.
Both the father and the son were silent, but they probably didn't realize that Liu Tan just randomly pointed out a place and didn't even think that Liu Tan knew nothing about the terrain.
As for why the embroidered-robed envoy didn't report it... it was because Liu Tan secretly warned him not to write down the dialogue containing the two lines of poetry: "Dare to teach the sun and the moon to change the new sky"!
Liu Tan really didn't know who the Embroidered Robe Messenger was, but he only needed to order that no one who heard it should say anything careless. Anyone who said anything careless would have their tongue cut off and be sent to be a mute slave!
The embroidered messenger thought about it and felt that there seemed to be something wrong with these two lines of poetry. In fact, they should have reported them originally, but for some reason they deleted this paragraph. Anyway, even if they deleted it, it would not make the causal changes before and after appear too prominent.
After wiping it off, the embroidered envoy thought that this was to save his own life. If the higher-ups felt that Liu Tan was restless and wanted to deal with him, the Fifth Prince would definitely not be in any big trouble, at most he would be kicked out to his fiefdom, but he, the embroidered envoy who had been following the Fifth Prince, was unsure what would happen to him.
Or... let's not talk about it. It's still not too late to send it up when there really is such a sign.
So a beautiful misunderstanding was formed.
Liu Tan didn't know that Liu Che and Liu Ju both had hopes for him and hoped that he wouldn't be so outstanding. At this time, he was designing the launching direction for the new city.
To be honest, the sewage projects of this era are actually quite backward.
Of course, it depends on the place. The sewage in Weiyang Palace is very high-end, but once you leave the imperial city, the sewage in other places in Chang'an City is not very good. This also leads to the fact that the glamorous Chang'an City actually has a dirty side. The richer the area, the cleaner and tidier it is. In the slums, even if the smell is not stinking, it is unbearable.
In fact, this is also one of the reasons why Chang'an was no longer the only capital in the middle and late Tang Dynasty. The city lacked sewage facilities and there were villages around it. Domestic sewage polluted the groundwater, which exceeded the carrying capacity of the natural environment over time, so the water quality began to deteriorate.
The high-ranking officials and nobles were naturally the first to discover it, so they moved to Luoyang, while the common people naturally remained in Chang'an.
Oh, this is what Liu Tan heard from others.
Nowadays, all sewage from Chang'an City is discharged into the Wei River. It is unlikely for such a large city to change, and Liu Tan does not have the courage, so he can only make some arrangements in the new city, at least to ensure that there will be no problems with the eating, drinking, defecating and urinating of nearly a thousand people.
You have to know that the water resources in the Western Regions are much more precious than those in Chang'an. If there is pollution, we won't even know where to move.
However, Liu Tan was not a civil engineering or water conservancy major, so he didn't know much about sewage discharge design. The only thing he knew was that he still remembered the historical materials he had read in the past, which contained sewage discharge diagrams of various dynasties. It was actually not difficult to copy them.
The only difficulty is that most of the schematic diagrams show sewage being discharged into the river, and looking at the locations of all the named capital cities of the flower-growing countries, there is basically a river around them.
Liu Tan: Here... there is an empty river valley!
Where should sewage be discharged to avoid polluting water sources?
He thought about it for a long time, and finally felt that it would be better to build a biogas digester, which could not only solve the pollution problem, but also provide another source of energy. Otherwise, in this Gobi Desert, firewood is a precious commodity. If there is no resource for heating when it gets cold, it will not be something that can be resisted by righteousness alone.
The setting of the biogas digester must also follow the principle of proximity. If it is in the Central Plains, it must be closer to the farmland, but here... there is no farmland, so as long as it is in the surrounding area, it will be fine.
However, due to the special nature of biogas, it is difficult to transport, so it is simply set up five miles southeast of the city.
After determining the location of the biogas tank, Liu Tan asked people to dig a pit first. The pit of the biogas tank does not need to be very large. In order to achieve high utilization rate, the biogas tank should follow the three principles of being round, small and shallow.
After sending people out, Liu Tan began to design the direction of the city's water supply and the planning of the city's buildings.
After racking his brains for a long time, he was just halfway through drawing when Jiang Chong hurried over and said excitedly, "Your Highness, there's a gold mine!"
Liu Tan: ????
