Li Yan sent Liu Bei and a group of dejected generals away, and returned to the villa with the movie projectionist. Pen ~ fun ~ pavilion www.biquge.info

Yang Yong calculated the income of each group of people according to the computer summary, and sent the corresponding rice to each group, which was distributed by itself.

Liu Bei saw a bit of a lot of things today, which could not be digested for a while and a half, and he did not make a decision on whether to withdraw the army.

However, in order to ensure the normal construction of the construction site and the development direction of Wei Minsheng, it is necessary to lay out Yiling County as soon as possible in order to absorb more human resources from the Central Plains.

However, the gang of robbers in Longdong Bay is a big security risk, seriously hindering the flow of people between the mountain villa and Yiling.

Wei Minsheng decided to take the initiative to completely remove this hidden danger.

As long as Wei Minsheng personally goes out and takes advantage of his real-world material support, it can completely have a deterrent effect.

I heard that there are many forks in the dragon cave, and if you go wrong, it will not only take time, but the most feared thing is to walk into a dead end, and be blocked and beaten by robbers who are familiar with the situation, so you will be very passive.

If it's much simpler in the real world, you can use a variety of small trackers to find the bandits' lair without you knowing.

But there is no GPS signal in this world, and other positioning and tracking methods are either huge or not easy to get.

In the end, Wei Minsheng still saw the mobile phone and came up with a way to use the Wi-Fi signal of the wireless router to determine the movement direction of the tracked item.

Originally, Wei Minsheng wanted to use a directional receiving antenna and a computer to determine the strength and direction of the signal, but after the experiment, it was found that in some specific environments, due to the diffraction of the signal, the directional antenna may measure the signal in multiple directions is similar, and the significance of tracking is lost if the direction cannot be determined.

In the end, I came up with a stupid solution, each of the three people held a mobile phone, kept a certain distance from each other, and judged the direction according to the strength of the Wi-Fi signal on the three people's mobile phones.

So, Wei Minsheng went back and bought a few cheapest smartphones and a wireless router with a strong Wi-Fi signal.

I also bought a 28Ah battery, and connected three 1A diodes in series to step down the voltage to use as a power supply for the router.

According to the power consumption of the router a few watts, this battery can be used for more than three days after being fully charged, which is enough to complete the tracking task.

As for the size and weight of the problem, it is easy to solve, after connecting the router and the power supply, put it in a wooden box.

In order to prevent the connection from being affected during the moving process, the battery was fixed with wooden strips, and the router was glued to the bottom of the box with transparent glue, and a partition was made on it, on which some decorative "jewelry" bought from the market was placed as a camouflage.

Like plastic pearls, glass gems, gold-plated ingots and other worthless things were installed, and seeing that the weight was not enough, they sifted and washed the broken tempered glass slag that others did not want on the side of the road, and installed a thick layer.

In order to eliminate the bandits in Longdong Bay this time, Wei Minsheng also made a lot of preparations, such as tear gas, gas canisters, gas masks and other things, and even prepared several large pockets of dried sea peppers that were not in good condition manually selected in the kitchen.

In order to avoid being discovered by others that those materials disappeared inexplicably, Wei Minsheng specially found a warehouse to place these things, and welded all the windows and doors of this warehouse, leaving only an anti-theft door for himself to enter and exit.

Due to the large space of the warehouse and the miscellaneous things of his own, Wei Minsheng also divided the warehouse into several areas such as tools, food, materials, weapons and so on according to the way of computer partitioning, and each area was further divided with containers, just like creating folders, to ensure that he could quickly find what he needed, and completely turned this warehouse into his own private storage space, and put everything he thought might be useful into it.

After preparing all this, Wei Minsheng found Li Yan and others, told him his plan, and asked Li Yan to find a unit with nearly 100 people disguised as rich merchants and servants from Shu Kingdom, with wooden boxes and other belongings, holding the weapons that Li Yan's subordinates used to use in Zigui, as if they were going to Yiling County to do business.

Dispatching nearly 100 people to protect property was also considered, as it was easy to make people suspicious if there were fewer people, and if they were robbed by other small bandits that might exist, the meaning of this operation would be lost.

A large number of people can reflect the importance of escorting property, but it can't be too much, otherwise it will be bad to scare Long Xiaotian so much that he doesn't dare to come.

According to what I learned before, this Long Xiaotian had more than 300 subordinates, and a team of less than 100 people could still eat.

The task given to them by Wei Minsheng is: once they encounter a large group of robbers, they can simply resist a few times, and then no matter what they bring, they will put it down and run, and the task of being robbed by the robbers will be completed.

Yang Xingbang and others, who have now become Li Yan's subordinates, originally came from Yiling, and they also encountered that gang of robbers on the way, so they naturally became the best candidates to lead the way.

Yang Xing led the way in front, and the people with the unit escorted the "jewelry" box and other belongings containing the router, lined up in a long snake formation, and walked slowly in the direction of Yiling.

Wei Minsheng took Wang Wushun, Wang Wenqing, Zhou Jincai and others to follow from afar, and taught them how to check the strength of the signal on the way, and numbered each mobile phone.

In order to judge the direction faster, Wei Minsheng took a mobile phone and walked behind, Wang Wenqing and Zhou Jincai walked in front, and each of them also brought a walkie-talkie with a headset.

The way of communication is to report a number by the mobile phone number plus the number of signal grids through the walkie-talkie, for example, Wang Wenqing's mobile phone is No. 1, if the Wi-Fi signal on the mobile phone is gone, it will be reported "10", if the signal is full, it will be reported "14".

Wei Minsheng took the No. 3 mobile phone, and according to the signal situation of the other two mobile phones, combined with the signal strength of his mobile phone, he could quickly judge the direction and approximate distance of the router.

In this world where there are no tall buildings to obstruct you, the Wi-Fi signal coverage is still relatively large.

At this time, the road is not as accessible as in the real world, but there are more people walking, and it naturally becomes a road. Those things that open roads in the mountains and build bridges in the water are not something that ordinary people can do.

Although the road is more than one meter wide, the places up and down the hill are relatively steep, so those modern off-road vehicles can't be counted on, and Wei Minsheng can't bear to walk dozens of miles on foot, so he found two villagers to make a slide pole and carry it behind.

The Yang Xingbang in front has not yet sent a signal through the walkie-talkie, so Wei Minsheng and others follow far behind, and the weeds and trees on both sides of the mountain road can well hide the figure of themselves and others, and in the absence of any fork in the road, as long as the mobile phone can search for the signal, it will not be lost.
