The three-way crossing is an important pass in Ansai, as its name suggests, it is a three-way junction, to the east to Yanchuan, to the northwest is Anding, and to the south is Ansai. Because the terrain is dangerous, easy to defend and difficult to attack, in the past, the officers and soldiers built a fire road pier at the key point, and there were twenty or thirty sergeants stationed there all the year round, until the rear of Jiajing gradually slackened. The rammed earth walls of the past are still well preserved, and many merchants use them as temporary shelters and resting places. After some cleaning and arrangement, this place is now the location of the Chinese army of the Ansai camp.

Luo Rucai has been here for two days, and he has not been idle during this time, according to the method discussed with Wu Wei before leaving, he has already set up a blocking position, and set up several obstacles on the way to the thieves.

The first barrier is thistle, which is simple and effective, and works well against the cavalry that restricts the thieves. This thing is the common equipment of the Ming Dynasty army to defend against the Mongols, mostly made of pig iron, does not need too high technology, looks similar to the thorn ling, there are four acute angles, scattered casually, there must be an acute angle vertically upward, now there are many cavalry among the thieves, and the thistle terrestris is just right. It's just that in these years, ordinary armies will never use thistle terrestris on a large scale like Wu Wei, this is the rhythm of defending with men and horses. Fortunately, Ansai's iron-smelting industry has begun to take shape, and the largest iron-smelting factory is run by Wu Wei, with sufficient manpower and advanced assembly line operations, and Wu Wei's order for 100,000 tribulus terrestris was completed in less than half a month!

The second barrier is barbed wire, which was widely used in World War I, it is not ordinary barbed wire, but a barbed twisted iron cable with thick iron wire, and if you don't pay attention to the palm of your hand, you will be cut with blood. It's also very easy to use, just roll it up in a circle and place it on the enemy's offensive line. Although it is simple, it is not easy to deal with, and if you are not careful, you will be cut, and if your clothes are caught in the spikes, you will often get tighter and tighter, and become a live target for the enemy. In modern warfare, barbed wire can be cut with sapper pliers, blown up with explosives, or even crushed with tanks, and there are many tight methods, but at the end of the Ming Dynasty, there was almost no solution! Wu Wei was also inspired by Spielberg's blockbuster "War Horse", and he was deeply impressed by the scene of the horse being entangled in barbed wire. Wu Wei chose a seller with the highest praise rate on Taobao, purchased a large number of anti-theft barbed wire, and the seller was also very considerate, and included a few pairs of cut-proof canvas gloves, otherwise Luo Rucai may have to spend more time deploying it.

Let's start with it first, and I'll make it up tomorrow morning, so please forgive me.
