Yang Li immediately called a meeting of everyone, and found that there was an unexpected person in the reinforcements of the Gray Wood Clan, it was the son of the old village chief Zhang, named Zhang Shukui, this young man had a white face and no beard, and he was seven points similar to his biological father.

Lao Zhang died, drank a few glasses of wine at a banquet, and when he came back, he was bleeding and couldn't speak, and when Zhang Shukui arrived, he was already dead.

Lao Zhang's younger brother Bai Er successfully ascended the throne, and his subordinates are all hunters of the Gray Wood Clan, and they have enough deterrent power.

Zhang Shukui felt that his father's death was unusual, and there was a lot of strangeness in it, but before he could find evidence, he was detained by Bai Er on the charge of treason, which strengthened his guess that Bai Er must be usurping power.

Fortunately, Lao Zhang has governed the clan for many years and is quite popular, and more than 20 clansmen loyal to the former leader came to the rescue that night and secretly released Zhang Shukui.

But everyone summed up that there were men and women in their own people, and it was almost impossible to take back the position of the leader, so they decided to leave the Ash Wood tribe and go west along the Luo River, seeking the assistance of the Yang Da leader in the river bay.

After walking a few miles, he met Yulia and a few others.

Although Mao Mei really wanted to kill the gray wood settlement, slaughter Bai Er, and leave Yang Jiao to be the queen, but thinking that the battle situation of her concubine in the north of the Luo River was unknown, she still decided to take this group of people to the Lieshan clan to support.

The next situation was when the archers of the Greywood Clan appeared on the flanks of the battlefield and helped Yang Jiao defeat the vanguard of the Black Blood Clan.

"There's still this one?" Yang Jiao slapped his forehead, "Why didn't you say it earlier?" ”

"Seeing that you have won the battle, I am happy to celebrate, and I don't want to ruin your interest." Yulia replied.

Who cares about the interest at this time!

Since the important personnel were present, Yang Jiao immediately held a meeting.

At the meeting, everyone spoke enthusiastically, and the summary was nothing more than to kill the Gray Wood Clan first, destroy the usurper Bai'er, let the leader of Xiao Zhang take the throne, and then gather all the forces of the three tribes to fight against the army of the Black Blood Clan here in the Lieshan Clan.

"Xue Pijiang, do you think so too?" Yang Li looked at the expressions of everyone, although the fighting spirit was high, but compared to before, he always felt that he lacked some confidence, after all, the army of more than 1,000 people was an extremely large group in the barbarian era, and the total number of people was actually about 1500-2000 people.

The young man scratched his head, he observed for a while on the contour map spread out by Yang Jiao, pointed to the soldiers who were cheering and celebrating outside, and said, "They are all excellent hunters, why don't we disperse and intercept the Black Blood Clan alliance in the wasteland." ”

Guerrilla?

This was indeed a solution, but Yang Li rejected the proposal.

Now the Hewan tribe is on the rise, and all production revolves around economic development.

The enemy's strength is ten times that of their own, and they can force their way into the village and completely destroy the economy of the settlement, regardless of harassment.

This year's bumper harvest of grain is stored in the barn, these are the capital for Yang Jiao to expand his territory and reproduce the population next year.

If you lose your base area, even if you fight guerrilla warfare for a few months and force back the coalition forces of the black blood tribes, what will everyone face next?

Facing the bitter winter of the Central Plains, a cold snap from Siberia will sweep through the land with winds and snow and ice, and the inhabitants who have lost most of their food will either starve to death or freeze to death.

Yang Li explained this truth to everyone, and everyone could understand it.

"Brother Yang, you said that this fight is not a fight, and it is not a fight if you don't fight, but I am really anxious!" Lieshan Candle scratched his ears and cheeks, depressed and abnormal, he really couldn't think of any other way, so he simply said angrily, "You guys run, run as far as possible, anyway, I'm going to stay here and live and die with the clan!" ”

"No, you have to withdraw." Yang Li made a decision that no one expected.

"Don't think!" Lie Shan Candle straightened his neck and refused.

Yang Li looked around at everyone and found that everyone couldn't understand their good intentions, so he reminded him slightly: "Look at the wooden fence of the mountain settlement, is it difficult to resist the siege of the army?" ”

Everyone said yes in unison.

"Look at our most elite warriors, are they hoplites armed with tomahawks and round shields?"

Everyone said yes in unison.

"So you still don't understand?" Yang Li saw that Yulia had already shown a look of sudden realization, so he was glad to sympathize.

"So we told everyone to pick up their shields, give up their defenses, and go to fight?" Yulia asked.

Poof, there's no big picture.

Yang Li's decision was very simple, taking advantage of the fact that the main force of the black blood tribe had not arrived, he moved all the more than 100 people of the Lieshan tribe, brought tools and food, gave up or destroyed the utensils that did not leave, and everyone crossed the river to the south.

On the side of the Gray Wood Clan, he only sent an envoy to discuss and ask Bai Er what his attitude was, and he could now pull out a maximum of twenty ordinary warriors in his hands, which would have little impact on the entire battle situation.

Moreover, the trading towns of ancient times were far less prosperous and powerful than those of later generations, and once a war broke out and the trade routes were cut off, they would be instantly beaten back to their original shapes and survive.

This is one of the reasons why Yang Jiao is now moving the commercial function of the riverbend to the gray wood tribe.

The wooden fort that Yang Jiao had begun to build before was about to come in handy in the next war, abandoning the fragile mountain settlements north of the Luo River and directly concentrating all the elites together for defense.

An army of more than 1,000 people came from afar, and the amount of food consumed in a day was an astronomical amount.

As long as Yang Jiao can hold on for half a month, the army of the black blood clan will be self-defeating.

So they have only one option, and that is to siege the city.

So where is the confidence of Yang Li's defense?

First of all, the entire terrain of the river bay land, surrounded by the Luo River to the north, formed a natural barrier, and even if the enemy army was able to cross the river, there was no space to camp on the plain between the river and the wooden fort.

"If they are determined to camp on the alluvial plains—look here," Yang Jiao's finger poked at the location of some wheat ear patterns on the map, "Well, now this farmland is my own camp, and the wooden fort is about seventy meters from the river bank, which is exactly within the killing range of the bow and arrow." ”

Xue Pijiang's eyes lit up: "Yes, if they dare to settle here, I promise to drive them back into the river with a longbow and feather arrows!" ”

Therefore, the black-blooded army can only choose to cross the river from other places, and then go around to the south to attack the wooden fort.

To the south is the main gate of the wooden fort, which is also the most complex and strong place in the entire city defense system.

Yang Li abandoned the bridgehead that was commonly used in the Middle Ages - in fact he had no intention of digging a moat for the time being, but instead leveled the ground fifteen paces away from the city gate and the city wall.

In this way, there is an interesting phenomenon in front of the wooden fort, nearly twenty meters away from the city wall, there seems to be a low slope, Yulia once questioned this structure, saying that this is not an enemy, originally our bow and arrow javelin can shoot the enemy farther away, now it is good, the enemy twenty steps away can use this dirt slope to cover themselves.

Yang Li said that this is not the case, you can play the role of a sieger and try to use the slope to cover yourself.

Yulia tried it and found that it didn't work.

How does this work, before approaching the city wall, the besiegers will walk through a gentle slope, and the extension of this gentle slope is the head of the city wall.

In other words, the slope is parallel to the trajectory of the wall downwards, so the besiegers cannot cover themselves with the help of a gentle slope.

And the firepower at the head of the wall can still output troops on gentle slopes.

Then Yulia is strange again, if the gentle slope is restored to flat ground, wouldn't it be more convenient to output firepower at the head of the city?

Yang Li said, don't assume that the head of the city is a female warrior like you like Valkyrie, or Huya and Xue Pijiang or something, you have to assume that the head of the city is all peasant soldiers who have dropped their hoes and just entered the battle to fight, and they use their strength to beat their mother's womb, and throw javelins to twenty meters at most, you look at the structure under the city wall?

Yulia looked down again, and suddenly she was terrified.

The gentle slope approached a distance of twenty paces, and then suddenly descended at a steep angle, returning to its original level level.

What does this mean?

All attackers who approached the walls of the city were to be confined to a distance of twenty paces below the city, huddled in the trench between the dirt slope and the city wall, like beasts in a trap, at the mercy of the fire of the city!

In other words, even the most ordinary farmer at the head of the wall can deal effective projectile damage to enemy troops huddled together below and on steep slopes.

Whether it's a javelin or a bow and arrow, under this ingenious terrain structure, almost a shot will never miss.

This is the power of engineering, Yang Li not only brought the city wall that can be walked and exported to the Central Plains in advance, but also integrated the combination of gently sloping moats containing the principles of ballistics into the city defense system of Mubao.

The Wooden Fort is no longer just a fortification, but a thorny, aggressive tool of slaughter.

The two towers are still under construction around the clock, protruding from the wooden walls, and it is expected that each tower will be able to arrange ten archers, which will be enough to form a three-dimensional fire strike at the dead corners of the city.

Yang Li's current residence, which is the main fort building of the wooden fort, can arrange twenty projection soldiers above it.

The outer walls of the main fort are scattered with firing holes and small protruding arrow forts, which are all output points to ensure the defender's lethality after the start of the battle.

During the Northern and Southern Dynasties, as well as North China during the Northern Song Dynasty, there were once Wu forts, which played a role in protecting the territory of a powerful party, and also provided a place for private soldiers and generals to train and survive.

Not to mention the castles that dotted medieval Europe.

Similar structures can withstand enemy forces several times their size, and are impregnable unless they run out of food or mutiny from within.

The castle designed by Yang Li has no aesthetic at all, one stone and one wood, all the functions are to ensure that the defense is sufficient under the premise of giving full play to the maximum firepower output of the castle for the purpose.

With all the people and the warriors returned, one hundred and thirty-one people from the Lieshan tribe, women and children, all carrying parcels and carrying their only possessions, and moved into the river.

The mountain settlements north of the Luo River were completely abandoned, and Yang Jiao concentrated all his forces in the river bay.

To be precise, the wooden fort of Riverlands, a fortress beyond its time, capable of temporarily accommodating hundreds of people, and its walls made of thick logs and clay could accommodate more than a hundred warriors at once.

The wooden castle was filled with the sound of sharpening blades and making shields.

Supplies from the settlement were transported to the castle in waves.

Three days later, Yang Jiao climbed to the top of the city and finally saw the scene north of the Luohe River.

An army of thousands of people came across the river in the dark, swimming, or making canoes, like ants.
