Fang Yuan arranged for Qin Zhan and Jing Jie to receive all the brocade guards, who were responsible for filling the gunpowder with the firecracker, as well as tying up the haystack that could resist the golden bow and arrows.

Fang Yuan, who returned to the room, locked himself in the room and prepared for a night battle.

The method of night vision, Fang Yuan has seen in various blockbusters and TV series, is to use infrared night vision devices.

During World War II, infrared night vision devices were used in the battlefield of the U.S. military's attack on the Japanese islands. The Japanese troops hid in shelters and tunnels without light, and fought around with the American troops. The U.S. military invested a large number of infrared night vision devices into the battlefield, and it was easy to kill the stubborn Japanese troops in the tunnel one by one.

Fang Yuan typed 'night vision device' in the search box, and when he looked at the price, the professional night vision device was at least two or three thousand yuan each, and the cottage one was about two or three hundred.

The battlefield is the place of life and death, and one mistake is one, or even several lives, and you must not use copycats that are unreliable in terms of imaging technology, resolution, and even distance.

If twenty brocade guards take turns firing a salvo in a three-stage strike, the night vision devices can be used in turns, and there is no need to buy twenty, ten night vision devices are enough.

But choose a professional night vision device, plus the shipping cost is 30,000 yuan a piece. The total price of ten night vision devices also reached a staggering 300,000 yuan, which is 3,000 taels when converted into silver.

Fang Yuan went out this time to be a public expatriate, and he only brought some broken silver with him, and now he was shy in his pocket, not to mention three thousand taels of silver, even three hundred taels or thirty taels of silver could not be taken out, how to find this huge amount of silver?

He paced back and forth in the room, his eyes finally fell on the several large boxes that Tian Hongyu carried, and his eyes lit up suddenly, isn't this ready-made gold?

These gold were used by Tian Hongyu to buy beautiful women in Jiangnan, in addition to Tian Hongyu's private collection of family property, there was also part of the imperial silver in the palace. The private use of Tian Hongyu, and even the gold and silver in the treasury of the palace will definitely cause the dissatisfaction of the national father-in-law, and even Emperor Chongzhen, and there is a possibility of killing the head.

But now is a critical juncture, the matter is out of power, Fang Yuan's plan is to borrow Tian Hongyu 3,000 taels of silver first, and then defeat the Golden Tartar, recapture the money looted by the Tartars, and then fill the vacancy.

Fang Yuan had this adventurous idea, coupled with his boldness by nature, he immediately took out the embroidered spring knife, and without saying a word, he cut off the hemp rope that bound the box with a swing of the knife, and opened a box, which was really densely packed with gold ingots, which was the same as the previous estimate, and what Tian Hongyu brought to Jiangnan this time was all gold.

Three thousand taels of silver, that is, three hundred taels of gold, Fang Yuan took out three hundred taels of large gold ingots, put them on the table, closed the wooden box, tied the hemp rope to restore the original state.

He put ten night vision devices into the shopping cart, and the system's default ordinary express delivery time is half a day to a day. After the arrival of the night vision device, Fang Yuan had to study the use of the method first, and also trained the use of these brocade guards, the time was too hasty, the situation was urgent, and the express delivery of the system could not gamble on efficiency, so he took a safe way and chose [Expedited Express].

"Doot toot!"

The system displays, "Expedited express, additional shipping fee of one hundred taels of silver, and the express delivery will arrive within three hours." ”

Fang Yuan looked at his watch, it is PM9:23 now, three hours later, that is, around 1:00 AM tomorrow, after receiving the goods, first familiarize yourself with the use of night vision devices, and then you can sleep beautifully, and there is a whole day to train the use of Jinyiwei night vision devices, in terms of time, it should be enough.

Although the expedited express delivery charges a sky-high price of 100 taels of silver, it can only be slaughtered by the system.

Fang Yuan chose [Expedited Express] and [Gold Payment], and the system took away his gold and recovered more than 100 taels of silver.

It is worthy of expedited express, the delivery efficiency of the system is really fast, within ten minutes after payment, the system has been shipped, and at AM1:00, the purchased night vision device will arrive.

Fang Yuan disassembled a night vision device, installed the battery given by the merchant according to the manual, and turned on the power switch.

Because although you can't see outdoors, it is not a lightless environment in the strict sense, but a low-light environment. In a low-light environment, infrared night vision devices can be completely invisible in the dark without using infrared lights as auxiliary light sources, without the dazzling red dots in previous TV dramas.

Fang Yuan blew out the oil lamp in the room, and then opened the wooden door and window of the room, it was already pitch black outside the door, and he couldn't see his fingers.

Fang Yuan held up the newly purchased infrared fluoroscopy and looked into the darkness through the sight, and the scene in the courtyard was unobstructed.

The gates, stone tables, wooden fences, and beams in the inn, the branches and leaves of the big trees in the distance, and even the eyebrows of a few night owls parked on the trunks of the trees are clearly visible.

Fang Yuan held the night vision device and walked around the post station in the dark night without bumping into anything.

He was playful, came to Qin Zhan's room, and knocked on the door.

"Who!"

The room resounded with Qin Zhan's impatient voice after being woken up and sleeping.

Fang Yuan didn't bother to answer him, and knocked on the door again.

Qin Zhan got up angrily from the bed, lit the candle, opened the wooden door, and looked out of the door, but there was no one in sight.

Fang Yuan, who was hiding on the side of the door, knocked out the candle in his hand with the back of the embroidered spring knife, and as soon as the fire was extinguished, the surroundings fell into darkness.

Qin Zhan thought that he had encountered a sneak attack, so he was so frightened that he hurriedly hid in the room, and he didn't even have time to close the wooden door.

"Bang!"

Qin Zhan, who had just taken a few steps back, noticed that someone had knocked on the back of his head, and he could accurately hit the back of his head in the darkness of not seeing things, people would never be able to do it, this was not a sneak attack, but, a ghost!

Qin Zhan's terrifying thought in his life was suddenly shocked and lost his three souls and seven spirits, but he couldn't see a little light in the dark night, so he could only rummage through the candlesticks.

"Bang!"

His wrist on the table was knocked again, and he quickly withdrew his hand in pain, and with the layout of the room in his memory, he groped his way to the bed, and was about to go to bed, when he was hit in the ankle again, and he was unsteady on his feet, and fell on the bed.

"Uncle Ghost! Spare your life! We had no grudges in the past, and we have no grudges today, why did you find me? ”

Qin Zhan had already decided that it was a ghost, and he was so frightened that he begged for mercy on the bed.

"Hahaha!"

Fang Yuan couldn't help but laugh when he saw his cowardice in the dark night.

Qin Zhan heard that it was Fang Yuan's voice, but when he raised his eyes, he still didn't see a single figure, and hurriedly asked, "Is it the leader?" ”

Fang Yuan made enough fuss, and fully proved that night vision devices can play a huge role in night battles, so he lit the candles on the table, and the room was lit again.

Qin Zhan saw that it was indeed Fang Yuan, and he was still holding a long box in his hand that he had never seen before, and looked at him dumbfounded, "Boss, can you see me in the night?" ”

Fang Yuan raised the infrared night vision device in his hand and said with a smile, "With this, you can see it clearly." ”

Qin Zhan was surprised to take his infrared night vision device and asked for advice on how to use it.

Fang Yuan taught him how to use it hand in hand, Qin Zhan studied for half an hour, and finally learned it, turned off the light again to test, and sure enough, through the lens of the sight, he could see Fang Yuan not far away clearly in the dark night.

Qin Zhan was really taken aback at this time, and stroked the night vision device in his hand, as if he was stroking a rare treasure, "Boss, where did this treasure come from?" ”

Fang Yuan still found the old excuse, "Franco. ”

Qin Zhan was skeptical, and asked in amazement, "I've seen a lot of Francois people on weekdays, but I've never seen them so powerful?!" ”

Fang Yuan was questioned by him again and again, and it was really difficult to deal with it, so he deliberately put on his face, did not answer his words, and handed him the night vision device to familiarize himself with and practice his hands.

This is the benefit of being a leader, Fang Yuan's words Qin Zhan must answer, and Qin Zhan is no matter how suspicious he is, Fang Yuan can also choose not to answer.

Qin Zhan had such a treasure thing, and immediately put his previous suspicions behind, and happily held the infrared night vision device, as if it were a treasure.

Fang Yuan, who returned to the room again, couldn't help but be overjoyed, and cheered to himself, "It really works!" ”

With this kind of high-tech gadget, coupled with the sudden sneak attack of the fire gun in the dark night, as long as the Houjin Tartar enters the post station to rest, it will definitely be defeated!
