Wang Jian’s wedding will be a half-month rest period as usual, and during this period, Heishui’s daily routine is handed over to Zhang Liao.

Zhang Liao was previously responsible for the "Impermanence Department" among the four ministries of Hei Water, which is a hands-on department, but he still has enough understanding of the entire operation system of Hei Water. It is still no problem to temporarily replace Wang Jian to focus on this stake.

The task of inquiring about the "Nine Life Returning to the Yuan Dynasty" issued by the commander's yamen was handed over to Zhang Liao, so that he could reach the information channels in the yamen of Wudian City, and collect relevant information as much as possible while ensuring his own safety.

Now that September is coming, not only has Fengri City reached a point of extreme heat, but Wudicheng City on the east has also entered the hottest season of the year, which is extremely hot.

In the past, this kind of weather was relied on the cultivation of heat resistance, or the chilled soup, or the palm-leaf fan shaking in the hands of slaves. But this year, the emergence of the air conditioner gave people in the city another way to resist the heat.

It is exaggerated to say that every household has an air conditioner, but as long as you can get a countertop in Wudicheng, there are air conditioners placed in it.

Compared with the effect of air conditioners, the consumption of mere spirit stones is nothing to the people in Wudie City, and they don’t care about silver and money. Therefore, the price of air conditioners in Wudie City has always been high. The best sellers are the most expensive types of gold and jade shells, while ordinary wooden air conditioners are sold in average.

The sales of air conditioners give Hei Water a great opportunity to penetrate. Using the installation and debugging of air conditioners as an excuse, you can easily enter some places that are generally difficult to approach, such as the garrisons of major forces, the mansions of people in the city, etc.

This invisibly put a layer of cover on these black water spies who used air conditioners as a cover. The recognition of all forces in the city was even higher, and it was not easy to arouse habitual suspicion.

At the same time, with the reputation of air conditioners and the replacement of land transportation, Hengshima Maxing and Gemei Air Conditioners quickly gained a reputation in the Wudicheng City.

In fact, it is not just a waste of the city. Similar situations are being staged in various places in the Jingjiu Dynasty. Ordinary people basically have no idea about air conditioners. They are expensive and cannot afford them at all. They think that the cost-effectiveness is too low. The main force in purchasing air conditioners are the nobles and merchants in the beautiful walls.

The situation is so optimistic that Hei Shui people will naturally not be idle. According to the requirements made by Shen Hao at the beginning, Hei Shui has been studying magic tools that can be used as eavesdropping or surveillance.

The functions of this kind of magic weapon are not complicated, and there are even many array molds that can meet monitoring and monitoring in the formation circle. You only need to get them regularly, but there is no teleportation function like Qianli notes.

But there is one premise that the plan is progressing slowly, and it can even be said to be stuck. There is only one reason, that is, the concealment cannot be perfectly solved.

As long as the formation is running, there will be magic fluctuations. The only difference is that it is "obvious" or "subtle". However, no matter in any situation, this thing is not easy to be put out and put into use. Because once an accident occurs, it will be a devastating blow to the current great situation of Gemei Air Conditioner.

However, things are moving forward bit by bit, and different usage environments have different requirements for the concealment of this formation.

For example, a magic array recently created by Hei Shui can maintain its function intact and have relatively high concealment. Unless the cultivation level reaches the later realm of the God-Clustering Realm, it is impossible to sense the subtle magic fluctuations in this formation.

It sounds like a waste, but in fact it is suitable for some places where there are few monks who appear or no monks at the back level of the God-Clustering Realm or above. For example, those merchants who are rich but have no status and rarely have powerful monks can use it.

Of course, it will not be used on a large scale. Hei Shui is currently mainly based on testing magic arrays, which are in the stage of using and modifying them while using. The merchants selected are also the kind that can be killed at any time. Once there is a mistake, they can seal the leak at any time.

These situations were sorted out by Wang Jian before Xiu Mu. Now that September has entered, it has been more than half a month since the small-scale trial, so this stage was reported to Shen Hao by Zhang Liang, who was temporarily in charge of Hei Shui.

“How is the effect?”

Zhang Liao was still the same as before, looking a little dull, but his temperament was much calmer than before, and even felt a little more fierce. It should have been developed by the more actions he had taken care of in the Impermanence Division.

"Sir, I've tried for more than half a month now. There are many problems with monitoring magic arrays. The main reason is that the image will be blurred due to the influence of light. There will be losses after extraction, and the effect is still a lot away from your requirements.

The monitoring has been very stable. As long as the words within four meters of the formation can be clearly collected, it is not enough to maintain a spirit stone for about ten days."

"What about long-distance communication? Is there a breakthrough in this regard?" Shen Hao refused to comment. What Zhang Liao said was just a simple basic function, and it is still far from his requirements. It is extremely difficult to use now. In addition to the concealment of the core problem, it is also a difficult problem to not be directly transmitted from a distance, otherwise the timeliness of this thing will be greatly reduced. You should know that once the intelligence loses its timeliness, it is basically equivalent to being useless.

"Long-distance transmission is still an old problem. Once long-distance transmission is turned on, the formation's mana fluctuations will greatly increase and its concealment will drop sharply."

"Let Feilong find some more ways to dig some formation masters, as well as weapon refiners."

"Weapon Refiner?"

"Well. Since the formation is stuck and difficult to achieve, try to find a breakthrough in refining weapons. If you continue, you must hurry up and not slacken at all."

Zhang Liao should have bowed and stepped back later. Although he was only a temporary agent, he did not dare to be careless at all. He hurriedly prepared to go back and contact Feilong. Now that the stall of Gemei Air Conditioner has been spread out, Feilong has withdrawn from the air conditioner business and has been honestly continuing to be his black market brother, but he has more and more contact with Heishui.

As soon as Zhang Liao left, Wang Yiming knocked in again and handed over a copper strip, saying that it was the Jingxi Punishment envoy who returned.

Shen Hao opened it and nodded with a smile. The previous "Draft Action Plan for the Commander of the Jingxi Heiqi Camp" was approved, and Jiang Cheng also added some expectations to this approval document, hoping that Shen Hao could achieve a brilliant achievement by the end of this year. At the same time, he also gave the support for the expansion of the organization and talismans and magical instruments that Shen Hao applied for.

In general, Jiang Cheng's support for Shen Hao is still as firm as ever.
