As the deadline drew nearer, the air on the border of the Pharyngeal tribe suddenly became tense, and the grass and trees seemed to be full of vigilance, ready to hear the footsteps from afar, and war was inevitable.

The number of meetings held by Pink became more frequent, but most of them were short meetings, and after arranging specific matters, the meeting was immediately dismissed, and officials from all walks of life were in a hurry to arrange it, and they did not dare to slack off in the slightest. The pikes, triplines, slings, and taps take the time to do their final workouts, and the defenders put the finishing touches on the pit, including covering, camouflaging, placing markers, and more.

Peony and I are also busy at various construction sites and training grounds all day long, guiding and correcting the work in various places.

Of course, we have a more important job, and that is to command the entire campaign. Pink was awarded the Commander-in-Chief of the Peony Anti-Multi Operation, and I was awarded the title of Chief of the General Staff and Deputy Commander-in-Chief of the Operations, and he did not confer military posts himself, and the three of us formed the Three Dragons Regiment, as the highest decision-making and command center, to lead the war of all the land.

For the invasion of the multinational force, we call it the Anti-Multinational War, and the side of the multinational force calls it the Weizu War, which means to maintain the ancestral system, because the ancestors are the ancestors of everyone, and they mean that the swallowing tribe has violated the ancestral system, which is disrespectful to the ancestors, and we as the descendants of our ancestors are of course obliged to defend it, so that they can whitewash the unjust war as a just war.

We secretly sent some spies to infiltrate the Hum tribe, and some went directly into the multinational force, and they passed the latest news back at any time, of course. It is impossible for them to run back immediately to report the news, because they are far away, and it is very easy to expose their identities if they leave in this way, and at the same time, the fighter plane is fleeting, and it is very undesirable to delay the information because of sending it.

They use codes to deliver messages, and only we know the content of the code, but the Multinational Force side does not know anything about it, as early as a year ago. When the Hum Tribe had just announced the sanction of the Pharynge Tribe. Pink has set up a secret intelligence organization, and the members of the intelligence group are relatively secretive, mainly for their own safety, as well as the security of intelligence. Of all the members of the firing group, only Dice knew it in his heart. The training of these members is all individual. There is no face-to-face contact with other BFIPU members. In this way, even if a member of BFIPU is caught, no other companions will be confessed. Therefore, the intelligence members sent to the outer tribe are all working alone, cooperating from a distance, and when one sends a message, those who stay nearby will send the information again, so that the information will gradually come back.

We also debated many times about what to use to convey information, and at first we were prepared to use symbols on objects to convey information, such as drawing symbols on trees or placing branches in a regular manner, but this view was quickly disproved. It is not very easy to select a few trees to mark in the huge forest, and the difference between the trees is not large, so it is a difficult task to find these marks, especially in an unfamiliar area, and it is even more difficult for the members of the BFIPU to achieve the transfer of information.

I told them the story of Jindan and their use of voice to transmit messages, and they felt that using voice to transmit information can be transmitted very far, and will not be unable to work because of darkness or other reasons, and can effectively expand the distance between the transmitters, improve efficiency, and avoid mistakes.

After discussion, we decided to use the sound of insects as a signal, and in order to better distinguish them, we chose three kinds of singing insects, which are cicadas, crickets, and gnats. The cicada calls indicate that the enemy is approaching us, the crickets call indicate that the enemy is resting in place, and the cicada calls indicate that the enemy is moving away from us. In general, we also use the length, speed and rhythm of the guò to express richer content, which is left to the dice to deal with.

In order to avoid us being disturbed by the insects in nature, the signals sent by the intelligence members are a little different from the natural insects, of course, this is only a very small number of red-haired dinosaurs can be heard, other red-haired dinosaurs are indistinguishable, thinking that it is the insects of nature calling. So you don't have to worry about the wrong information.

One day, Dice received information that the multinational force had been mobilized, and all 8,000 troops were dispatched, forming a four-way column to move forward, the team was dozens of miles long, mighty, and everywhere it passed, the smoke and dust were billowing, and where the footsteps were stepping, it was difficult to see living creatures, even if it was hard wood, it was trampled beyond recognition.

We decided to respond according to the first set of combat plans.

Arrangements have been made for the movement of the masses in the border areas, and the pikes, slings, triplines, and taps have been put in place and ready to be dispatched and commanded.

BFIPU is constantly sending back information indicating the location and orientation of the multinational force, and based on this information, we can roughly determine the general direction of the enemy's possible invasion of us in order to facilitate defense and attack, and of course, we have other ways to get them into our intended defensive locations.

Only by entering the defensive area we have set up can we strike at the enemy more effectively and achieve better results.

The Hum tribe is the northern neighbor of the Pharyngeal Tribe, and the border is a tall arbor forest that is more than ten kilometers wide and hundreds of kilometers long, and this area is a public area, which can be entered casually, but cannot be inhabited for a long time. In the world of red-haired dinosaurs, the border line is generally like this, relatively wide, to avoid disputes between the two sides over border issues, and there are often few fruit trees in the border area, so that there is very little red-haired activity, so that the relative silence between the tribes can be maintained and undisturbed.

The border line is a large area in which members of two tribes can move freely, but they cannot cross this area to each other's territory, which is a cross-border, which will lead to disputes between tribes, and the two sides will have to negotiate or other ways to resolve the dispute, and sometimes it may exacerbate the conflict and lead to war.

The edge of the border line is marked, so that you can ensure that everyone does not cross the line, the initial sign is that the tribal leader pees on the tree, and the other party smells the leader's urine and knows that this is his tribe, and can not go any further. But this method has a big drawback, because the border line is too long, and the leader has to walk in such a circle for many days, and he has to bring a lot of water, and he has to drink water constantly to pee. Because the urine is formed too quickly, the smell of urine is often insufficient, and it can be smelled very well, and after a rain, the previous efforts are even more wasted.

So, we thought of another way to mark the area of the boundary line, and what is the best way to do it? (To be continued......)
