Another five days passed, June 24, south of the city of Luoyang.

Li Su only took Zhao Yun and a dozen other horses, and got two carriages, first incognito and pretended to be a business traveler to secretly inquire about the news. All of them wore additional robes over their armor, and none of their weapons were in their hands.

Dian Wei and the 500 guards were still at the Nanyang boundary outside Yique Pass, pretending that Li Su was sick and couldn't walk, and stayed for the time being.

"Is this the Bi Gui Yuan that the first emperor asked hundreds of officials to pay for four years of 'palace repair money' before it was fully built? It's really magnificent, and providence makes people. Less than two years after it was completely repaired, the first emperor died, alas, the people and money were lost. ”

It was the first time for Zhao Yun and the others to arrive in Luoyang from Yique in the south, so they couldn't help but blame when they passed by Bi Guiyuan. He is frugal by nature, and he can't get used to Liu Bei's wanton distribution of spoils after entering Sichuan in history, so he dares to complain about what Emperor Ling did.

Li Su lifted the curtain and reminded in a low voice: "Zilong said cautiously, we can't reveal our identities in Jin, we must be careful everywhere." ”

Zhao Yun hurriedly apologized: "It was me who was careless." ”

The group slowly crossed Luoshui and entered the city from the Kaiyang Gate in the south of the city, because there was no festival, the officers and soldiers guarding the city were naturally tortured strictly, and after reading the talisman and asked:

"Yizhou people? What are you doing in Luoyang? Didn't you say that the rice thief made a mess and the road to Shu was impassable? ”

Of course, the identities of those soldiers on the talisman are true, they were issued by Liu Bei's Taishou, so there is no flaw in their origins.

Zhao Yun replied according to the rehearsed words: "It is a merchant in Shu, I heard that Zhang Lu was destroyed, and I want to come to Shu Dao to isolate it for several years, and the price of Luoyang tea will definitely be expensive, and I will sell wild tea in Shushan so far." ”

The eyes of the soldiers defending the city lit up: "Is it Shushan tea that is transported?" The tax is not light, come on, carefully check the amount and pay the tax in full! ”

Zhao Yun forgot about this, after all, he had been following the army before, who dared to collect taxes, and he was suddenly a little annoyed.

But Li Su pulled him in the car window, and Zhao Yun immediately calmed down and paid some money to cover up.

Anyway, there are not many goods, and most of the follow-up tributes are still in the Dian Wei army, and the amount that Li Su brought this time was to privately contact his own people to give gifts.

The gatekeeper received the tax in full, was overjoyed, and no longer strictly checked the identities of the guests in the car, and directly let them go.

……

After entering the city, Zhao Yunfu went to the window of the car and asked softly: "Zhonglang, or go to Cai Yushi's house first as planned?" If it is still early today, will it reveal our identity? ”

Li Su: "Of course, when the time comes, you will take my token and report it in person, which is very secretive." ”

Zhao Yun: "Huh"

The "Cai Yushi" they talked about was of course Cai Yong, and they also arrived in Nanyang, and initially inquired about the current changes in the DPRK, especially the focus on Cai Yong's movements, knowing that Cai Yong was finally conquered by the imperial court for the second time at the beginning of this year, about March.

This time it is a separate expedition, not a "fifteen Hongru wholesale expedition" like last year, so there is no problem of "after Zheng Xuan and Chen Ji refused to conquer, Cai Yong's separate recruitment is too faceless".

As a result, Cai Yong finally re-entered the court a month and a half before the death of Emperor Ling and was appointed as the imperial historian - to say an aside, although because of the butterfly effect, Cai Yong's requisition as an official was half a year ahead of schedule, but the starting official position has not changed.

This is not a coincidence or historical inertia, but the unspoken rule of the officialdom of the Han Dynasty is that for officials who have been deposed from the opposition, they are once again recruited and recalled to the court, and the official positions granted at the beginning are about the same as when they left the office.

Cai Yong was a 600-stone speaker when he was dismissed twelve years ago, and now he is naturally a 600-stone servant of the imperial history, nothing more than a subordinate official under the former Shi Luxun system, and the latter is a subordinate official under the Shaofu system. (Guangluxun and Shaofu are both Jiuqing)

But people like Cai Yong, after all, have accumulated a lot of knowledge and prestige in the past 12 years in the field, and in this life, he has co-authored "Refutation of Disasters and Differences" and "Treatise on the Blessing of the Palace" with Li Su, so after doing the history of serving the emperor, he will definitely be promoted quickly to catch up with the qualifications accumulated in the past 12 years.

Although it may not have the speed of the rocket in Dong Zhuo's hand in another life, it will not be too bad to think about.

A quarter of an hour later, they found the front of Cai's house. It was also at this moment that Li Su vaguely realized that it seemed that the news that they heard about "Cai Yong was conscripted as a servant of the imperial history" when they were in Nanyang had indeed expired.

Cai Yong's appearance in this court is like a city, how can he not be a servant of the imperial history, he must have been promoted again in the last two or three months, and outsiders don't know.

Zhao Yun took the token and a gift money given by Li Su, and asked the servants of the Cai Mansion to go in and pass it on, and some of the guests at the door were very dissatisfied with this uninvited guest who tried to cut in line, but after a while, the change in things surprised them.

Cai Yong personally ran to the door, opened the curtain and whispered a few words to Li Su, and then helped Li Su out of the car with his own hands, and also covered Li Su and the other guests in line to prevent them from seeing Li Su's appearance.

Because the weather was hot, Li Su also happened to cover his face with a folding fan, so he was even more unaware -

He invented the folding fan last autumn, but it didn't spread for a long time because it was cold. But half a year after the invention, catching up with the heat in the early summer of this year, the nobles of Luoyang found that the folding fan was a pretending artifact, and gradually began to buy it.

The wealthy businessmen led by the Zhen family also began to sell and imitate. Because it just appeared, the price is a bit abnormally high, and a random folding fan can be sold for thousands of dollars. Now there are at least thousands of folding fans in Luoyang City, and you can't recognize Li Su when you look at the fans.

After turning into the second gate of Cai's mansion, Cai Yong asked eagerly:

"Didn't the virtuous son-in-law follow General Zhenxi to pacify Zhang Lu and investigate the inside story of the case of Shu Dao severance? Why did you suddenly come to Beijing in secret? Could it be that Zhang Lu has been reconciled? If so, why not report to Your Majesty and the General first? ”

Li Su also gave Cai Yong a simple salute out of etiquette, explaining: "I'm ashamed to say that earlier this month, I was still running around in the Qinling Mountains to quell the rebellion and pursue Zhang Luyu's sins, and I only left the Qinling Mountains and went to Xiangyang ten days ago, and I learned that Your Majesty had ...... more than two months ago

I brought the Zhenxi General Xugong Recital Sheet, or written to the first emperor, I was afraid that it would be a bit undesirable to hand it over directly, so I left the servant outside the Yique Pass, and first went into the city to inquire about the news, and saw if there was anything that should be disposed of in advance. ”

Cai Yong nodded, introduced Li Su into the inner hall, and then retreated, leaving no outsiders in the house, just went to his daughter's boudoir and called Cai Yan out to meet Li Su and catch up.

Li Su also took out some fried tea and put it on the desk, which was regarded as the original meeting gift.

These teas are all wild teas sold by merchants in Shu, not planted. Li Su had already concocted it when he got it, just like matcha, so he couldn't revive the tea leaves into fried tea.

But he can finally improve the tea drinking process, no longer add salt and peppercorns, and only drink pure bitter green brewed matcha.

In order to teach the new way of drinking tea in the capital, Li Su didn't have to be polite to Cai Yong, he opened it in front of him after giving the gift, and then brewed three cups and one cup per person.

Cai Yan rushed out like a deer when he heard the news, and when he saw Li Su making tea, he was a little timid and embarrassed, and he recovered a little and walked over slowly: "Senior brother, don't come unharmed, it's hard all the way." ”

The engagement is still a secret, and Cai Yan is used to continuing to call his senior brother no problem.

Li Su said a few gentle words to her to show comfort, and then Cai Yan obediently sat aside and drank tea, not disturbing the adults to talk about business for the time being.

Cai Yong had the opportunity to speak, and told Li Su some precautions on "how to explain that the title on the memoir was written to the first emperor", and then asked about the results of Zhang Lu's crusade and whether there was any evidence related to Liu Yan's instructions.

Li Su was about to say this, but he picked up the boat: "We checked some human and documentary evidence. Many captives said that Liu Yan couldn't wait to punish dissidents in Yizhou since the end of last year.

He killed Qianwei County Shou Ren Qi without authorization, and the former Ba County Taishou was killed by the local thief Gan Ning, and it was reported to the court that Gan Ning committed his own crimes, but later we captured Gan Ning, and found that there was also Liu Yan's connivance in this.

In addition, a number of captured rebellious officials testified and formed confessions, saying that Liu Yan had built the Tianzi Luan Yu in Shu County at the end of last year and used six chariots of gold root cars.

We also seized some letters between Zhang Lu and Liu Yan, which contained more contradictory words, and captured Zhang Lu's own brother Zhang Wei alive. ”

Cai Yong was stunned: "Let me teach Liu Jingsheng how to distinguish the authenticity of the handwriting of documentary evidence?" What do you mean? ”

Li Su: "I have a lot of letters from Zhang Lu and Liu Yan here, some of which are related to the reverse case, and some of them are purely common, with no evidentiary significance.

However, when Zong Zheng ascertains the facts of the case, he must distinguish the authenticity of the handwriting of the documentary evidence. Taishan can teach Zongzheng when he doesn't know how to distinguish them: first copy a few copies of the contents of Zhang Lu's homely letters in other people's handwriting, and then show these copies to Zhang Wei together.

Let Zhang Wei recognize which ones are Zhang Lu's handwriting, or Liu Yan's handwriting, and promise that if Zhang Wei can recognize it, he will spare him to die, or let him die a happy death without having to abandon the city - Zhang Wei was captured when our army broke through Yangping Pass, and later isolated from the outside world, he still does not know whether his brother is dead, and can only speculate that Zhang Lu must have been roughly pacified when I sent him to Beijing. ”

This idea of "criminal investigation and cross-examination", Li Su taught at the Public Security University in later generations, of course, it was easy to come by, don't look at the fact that he taught a negotiation expert course, he was exposed to it in the same university, and he basically understood the common sense of criminal investigation.

But Cai Yong listened and was amazed at the prospective son-in-law's thoughtful thinking in solving the case, and even had a slight bad premonition.

He waved his daughter to step back first, and then asked Li Su: "Those letters...... Can you show me? ”

Li Su originally asked him, of course he showed it.

In this world, the imitation of copying handwriting is the most similar, the first is Zhong Xuan, and the second is Cai Yong - Cai Yong's calligraphy is actually better than Zhong Yong, but because he is good at writing, he does not need to imitate others, so the imitation skills are slightly inferior, and it is completely based on the basic skills of calligraphy.

And Zhong Yong's imitation is good because he has been copying Cai Yong's body for more than ten years.

After Cai Yong took Li Su's letters, he flipped through them a little quickly, and soon a little cold sweat fell: "Virtuous son-in-law...... IMHO, these rebellious beliefs really seem to be true when you look at the content, but ...... Their handwriting, like the letters that write homely contents, is inherently plausible! ”

Li Su smiled and lowered his voice to the lowest: "Then bother Taishan to copy it again, you can ensure that the Cai family will be rich forever, the world will be peaceful faster, and the people will be grateful to you." ”

Going to Zhong Xuan to fake, although the craftsmanship is better, but Zhong Xuan's friendship with Li Su has not reached this level, and Li Su has to worry about whether Zhong Xuan betrays him.

PS: I thought about it...... There is too much foreshadowing in the first two chapters today, and there are too many background explanations, so I will add another update.

In addition to the conditions for adding more than I said last time, I thought about it again and again, or add another article, and in the future, if you encounter the following situations, it is also possible to add one more free of charge on the same day:

First of all, when you encounter a side plot, the protagonist can't appear for two days in a row. In order to get through these plots as soon as possible, the three watches will be added to the regular state of that day.

Secondly, if you encounter a large section of war fighting scenes and battle scenes that do not have the opportunity for the protagonist to perform more than two chapters, one update will be automatically added on the same day.

Finally, even today, there is a lot of background of the times and farming materials that have to be paved, and a change is also added.

That's it. We don't treat readers who chase more every day. Make sure that you always have to advance the main line and the main character's plot every day.
