Chuanzhuang is a business.

Engraving communication wafers is rented to outsiders. Some large counties have this kind of business, but the price is extremely expensive.

The sky-high price of two thousand two thousand and a quarter of an hour can directly dissuade most people from thinking about it.

Generally, they are used when some big businessmen pass on important business information, or when aristocratic families pass on important information.

The shopkeeper of Vientiane City Communications Store is a master, a master of the fourth level of integration.

Seeing two low-ranking sixth-grade people coming in, the shopkeeper didn't show any sign of neglect.

Because as long as you walk into this communication village, it means that the other party has something like a communication source crystal in his home.

After handing over the banknote, the shopkeeper led the two of them into a secret room, bowed and left silently.

After Xu Xinyao briefly checked the surrounding soundproof formations, she walked to the huge crystal in the middle of the secret room and began to carefully check the communication formations.

Because most of the news spread through the communication bank is confidential, and there are benefits to be gained from it.

Therefore, it has happened more than once in the past that a communication village took advantage of the fact that most people did not understand the formation patterns, and manipulated the formations of the communication crystals, thereby eavesdropping on customers' secrets and selling information.

Although this kind of thing was started by Lou Ji's old aunt, Xu Yuan and Xu Xinyao still had to guard against it.

Looking at Xu Xinyao's general inspection, Xu Yuan suddenly asked curiously:

"Xinyao, how much does it usually cost to activate this kind of communication crystal?"

"If you don't use it continuously, you won't need money."

"Ah?"

Xu Xinyao used Yuan Qi to inspect it carefully and replied softly: "This kind of source crystal usually comes with its own spiritual array. When not in use, you can accumulate the heaven and earth Yuan Qi little by little in the spirit storage pool, um. Probably underground.

A place about twenty meters away."

Xu Yuan smiled and said: "One-time investment, huge profits."

Xu Xinyao shook her head:

"The materials for this formation are very expensive. Not counting the remuneration of the formation master, it costs nearly 200,000 taels of silver."

Xu Yuan smacked his lips: "The imperial court is really rich, with so many counties and counties having one person."

Converted into the currency of the previous life, it cost 300 million yuan to build a landline. Although the development direction was completely different, the productivity of the Great Yan Dynasty was still high.

Xu Xinyao smiled softly:

"Third brother, it was all built bit by bit, and there are no counties with many communication crystals. Except for border towns that need to report military information, some other small counties rely on official roads to report to the county town."

After all,

Xu Xinyao slowly straightened up and whispered:

"There is no problem with this communication source crystal. I have already contacted my father's Tianxun Yuanjing."

Probably because he was dealing with government affairs or something like that, Xu Yinhe did not answer the call immediately.

Xu Yuan leaned against the wall and chatted casually with Xu Xinyao:

"Xin Yao, if you charge for a large formation like Wanxiang Zongjian, what is the general reward?"

Xu Xinyao sat on the ground, leaned against the wall, glanced at her third brother, pondered for a moment, and said:

"Probably between 200,000 to 300,000 taels."

"." The corners of Xu Yuan's eyes twitched.

Xu Xinyao said with downcast eyes:

"Third brother, you don't have to be so surprised. The main reason is that large arrays are valuable."

Got it, technical products, and city-scale technical products.

Thinking about it, Xu Yuan's eyes looking at Xu Xinyao became a little painful.

Three hundred thousand taels

Four points and five small goals were given away as soon as he was told. Aren’t these four sisters more capable of spending money than he is?

When I go to Wanxiang Sect, I have to collect this debt together.

After making up his mind, Xu Yuan sighed: "Did you give them the formation diagram?"

Xu Xinyao shook her head: "Of course not. That kind of array is priceless. I am responsible for the core array."

Xu Yuan was slightly silent and asked in a low voice:

"By the way, how long will it take for the Gewu Institute to develop the Xunyuan Crystal that day?"

He really wants to get that thing. With that thing, he can shake people at any time.

Xu Xinyao whispered: "That kind of thing is very difficult. It cannot be powered or activated. Only high-level cultivations above the second level can use it."

Xu Yuan glanced at the Sumeru Ring on her finger:

"Can't you use this Sumeru Ring to provide energy?"

Xu Xinyao shook her head.

"Why?" Xu Yuan asked.

Xu Xinyao felt a little depressed because of the mention of Shengshan County, but she still hugged her legs and replied in a low voice:

"Once the Xumijie's suspended stone and the Tianxun Yuanjing's white radiant crystal communicate with each other, they will generate Qi, the grain pattern will also melt, and the nanocrystal attached to the suspended stone will also explode."

"."Xu Yuan.

Imperial Capital,

Outside the gate of Wuchenghou Mansion, the black dragon carriage representing the prime minister of the dynasty once again drove out of the thick red gate.

Compared with the last time, there is one more man in Tsing Yi in this spacious carriage.

Two young and old men with similar faces sat opposite each other, and the carriage was filled with an elegant and light smoke-free fragrance.

Xu Yinhe looked at the eldest son in front of him, shook his head and said:

"My father has already said that even if you come to propose marriage in person, Marquis Wu Cheng will not allow you to get married. In about a day, the fact that you failed to propose marriage will spread throughout the imperial capital."

Xu Changge's face was stern, and his emotions could not be seen clearly in his narrow eyes. He just said:

"There is a high probability that marriage will not be easy for a long time."

Xu Yinhe said:

"It's an expedient measure, and even if it lasts forever, it won't necessarily be suppressed."

Xu Changge raised his eyebrows when he heard this. There was no displeasure in his eyes, but curiosity:

"Father, can you elaborate a little bit more?"

Xu Yinhe said very directly:

"I asked him to deal with the affairs of Wanxiang Sect, and there is also Xinyao by his side."

"What happened to Wanxiang Sect in Shengshan County?"

Xu Changge frowned slightly: "With only 40,000 black scale troops, will Changtian and Xinyao be in danger?"

After Xu Changan died, Xu Changge could only step in and start taking over some affairs. When what happened was passed on to Xu Yinhe, a copy would be sent to him at the same time.

Xu Yinhe's eyes were a little complicated, but eventually turned into a smile:

"You, the eldest brother, protect them too much. Xinyao is protected too well. Changtianqian is too indulgent. They will always grow up."

Xu Changge was silent for a moment, exhaled, and slightly raised the corners of his lips:

"Is Changtian now able to take charge of his own business?"

Xu Yinhe did not answer directly, if he has any suggestions:

"I asked Lou Ji to tell Yi Tian to send two painting skins to Changtian and Xinyao."

Xu Changge's eyes paused:

"It's really good to conceal your identity."

"Hmm."

Xu Yinhe nodded, glanced sideways at the crowd on the roadside that had become quiet, and continued:

"I also arranged for someone to appear in Anxi County pretending to be Chang Tian."

Hearing this,

Xu Changge was quiet for a long time, then his pupils suddenly shrank, and his dull expression turned a little excited:

"Father, what do you mean?"

Xu Yinhe turned his eyes:

"Yes, I'm going to train Chang Tian."

A little late
