Dress up as a queen and start the game with a card drawing system

"All enemies who pass through this wall of light will appear in this jade tablet."

Qi Yun took out a handful of jade tokens, controlled them with her mental power, and flew them in front of the generals.

Everyone quickly took it with both hands.

"Activate with mental power."

The generals followed the instructions and poured their mental power into the jade tablet, and saw the mini map of the six states that Dayu had already wiped out.

On this map, there are eighty-one white light spots, which are exactly where Qi Yun buried eighty-one boundary monuments.

There is a yellow dot near the white dot that represents the boundary monument next to Qi Yun. Surrounding the yellow dot is a circle of blue dots, and outside is a bunch of neatly arranged green dots.

They were all experts in marching and fighting, and everyone understood its principles at a glance.

The white dot is the location of the boundary monument, the yellow dot is Qi Yun, the blue dot is the generals with the jade tablets in their hands, and the green dots are the Dayu soldiers outside.

There are also the people in Yingchuan in the rear, who are also densely populated with green dots on the map.

Qi Yun explained: "If there is an enemy invasion, it will be displayed as a red dot on it."

Hua Mulan said excitedly: "It's amazing! With this formation, we can know the movements of our enemy and our army very well!"

There is a saying in the art of war: Know yourself and the enemy, and you will be victorious in every battle.

Being able to grasp the enemy's movements in your hands is already invincible!

Unless there is someone among the enemies who is powerful enough to kill countless people in one blow, they will not be afraid of them no matter how many come!

"Not only that, these eighty-one boundary monuments also have special effects. With the boundary monument as the center, there is a shelter within a radius of 100 meters."

"As long as Dayu's soldiers and civilians are free to enter and leave the shelter to avoid temporary dangers, zombie monsters and attacks from foreign objects cannot enter this area."

It's a bit like the protective circle that Sun Wukong drew for Tang Monk.

She scattered the boundary monuments on the official roads of the five states, and stationed people at each place.

If you encounter a large number of corpse monsters, people who are active outside can immediately run to the safe area near the boundary monument to temporarily hide and wait for help.

In the current defense map of Dayu, the core area in the center is Yingchuan City, the edge of Yingchuan is the four major states, and then Shangjing.

Originally, Hengyang and Xianzhou had flat terrain, rich water and soil, and rich products. They were the two most valuable pieces of land for Dayu and should not be abandoned under any circumstances.

However, now that they all have mutated rice, they have enough food.

As for other crops, the output of Qi Yun's Xianfu and Liuxian's Beiling is enough for Dayu's population of less than 10 million, so planting conditions are not necessary considerations.

There are currently no people living in the Five States. Only some cities with important geographical locations or with mineral deposits nearby have rebuilt city walls, stationed troops to garrison them, and sent people to mine the minerals.

Once a zombie monster crosses the border, the number and marching route of the zombie monster can be seen immediately on the jade plate.

The generals of each city can directly lead people to encircle and suppress them.

The land of the five states is the reserved combat buffer zone to ensure that the hinterland of Yingchuan will not be disturbed by any attack.

[Just in case you think it’s abstract, I just made a random map and put it in a paragraph]

Yingnan City and Yingchuan City can accommodate the current population of Dayu, so there is no need to worry about not being able to accommodate even one Yingchuan Prefecture.

When the population increases in the future, Qi Yun will have more capable soldiers, who can meet the requirements for the defense of more areas. It will not be too late to slowly expand the residence of Dayu's people outwards.

In addition, Qi Yun also had people transplant and plant a large number of trees in areas outside the five states.

These woods can not only be regarded as a line of defense, but also allow Yunzhongjun's tribe to live and reproduce, and at the same time monitor the movements of the zombie monsters outside the formation.

Some more capable warriors or mercenaries can also venture outside the boundary monument to hunt zombie monsters.

Today, the largest group of zombie monsters on the mainland is the second level, followed by the third level and the first level.

At the fourth level, the number of zombie monsters began to decrease precipitously.

When Qi Yun began to clean up the corpse monsters in Dayu, the members of the corpse monster research institute specially established under her continued to analyze and collect statistics on the corpse monsters.

According to incomplete statistics, there are about 1 million level 3- zombie monsters in the territory of Dayu, but there are only hundreds of thousands of level zombies, and even less than tens of thousands of level zombies.

Now that there are enough test specimens, the research team has analyzed some detailed information about the corpse monsters.

The fourth level is a threshold for zombie monsters. After the fourth level, sanity begins to be born.

Just like a human cultivator going from refining Qi to building a foundation, this is a qualitative change to a quantitative improvement, and many zombie monsters will be stuck at this level for a long time.

In addition, the zombie monsters are not a seemingly harmonious group. There is also opposition and competition among the zombie monsters that have given birth to wisdom.

Every group of corpse monsters they encountered listened to their leader because there seemed to be a strange mechanism in the souls of the corpse monsters.

That is, as long as they are within a certain range, low-level zombie monsters will definitely not be able to resist the orders of high-level zombie monsters.

For example, if a fifth-level zombie monster is within the control range of a sixth-level zombie monster, then even if the sixth-level zombie monster asks it to commit suicide, it can only do so. It is so overbearing.

Qi Yun calls this situation hierarchical suppression.

And those zombie monsters that have developed intelligence obviously understand that there is hierarchical suppression among them.

No one wants to become a vassal of other high-level zombie monsters, and have their life and death controlled by others.

Therefore, these fourth- and fifth-level zombie monsters usually take their vassal zombie groups to deliberately avoid places with higher-level zombie monsters.

In the same way, in the vassal zombie group under each zombie leader, if anyone is about to break through to the same level as the leader, then he will be eaten by the leader without hesitation.

Therefore, those zombie monsters who have just reached the fourth level and find that they are already vassals will subconsciously suppress their own realm and maintain themselves at a lower level than the leader.

This was discovered through statistics of data collected from various armies during half a year's settlement.

Because when everyone leads the battle against these small groups of zombie monsters, this phenomenon often occurs——

When the leader of the army kills the leader of the zombie swarm with his own powerful combat power, many first-level zombie monsters in the zombie swarm will break through in spurts!

For example, after the leader of a zombie group led by a fifth-level zombie monster is killed, many fourth-level zombie monsters in this corpse group will quickly break through to fifth level!

This unexpected situation often catches the generals by surprise.

After all, in human cognition, if you can first take the enemy general's head in a battle, the enemy's morale will be greatly weakened, and then they will be defeated naturally.

They had never seen this kind of scene where the enemy's leader died, the morale of the entire enemy army soared, and they collectively broke through.

Cheng Hu's Black Tiger Army suffered a big loss because of this incident.

When he led his troops to clear out the group, he encountered a group of corpses led by a fifth-level zombie monster. He ordered snipers in the army to shoot the leader of the corpse monster to cheer up, and then ordered a charge.

Unexpectedly, as soon as the two armies fought, the soldiers of the Black Tiger Army's forward battalion were almost maimed by the zombie monsters that broke through collectively!

Fortunately, he called for help in time. Wu Qingfeng and Zhao Yun who were nearby saw the signal, flew over quickly, and worked together to rescue the Black Tiger Army.

Otherwise, all the Black Tiger Army might be killed!

Even so, the Black Tiger Army also lost more than a thousand people in that battle.

This was the most damaging incident in this Qing campaign.

Later, Qi Yun announced to the entire army that when facing the zombies, everyone should save the leader for last kill, so that the casualties in the battle with the zombies did not continue to increase.
