The kobold Pabukar with a hoe and thousands of his men was desperately digging tunnels.

As a second-order hero-level kobold, the hoe in his hand danced fast, and in a minute, he was able to dig a tunnel one meter deep and two meters high in the ground.

With his help, a steady stream of dirt was carried to the ground in baskets by the kobolds.

on the ground.

The kobolds were not idle, and they piled up the soil one by one on top of the two-meter-high Quadrangular Hill Pack, increasing the height of the Quadrangular Hill Pack.

From time to time, you can also see some kobolds digging up the tunnel, digging through the four-sided hill bag, and digging out hidden holes in the four-sided hill bag.

And these holes are the firing ports where they can shoot with a steel crossbow.

In order to ensure solidity and stability, each quadrangular hill bag is two meters high, covering an area of four square meters, with four sides on the front and back and left and right plus the top surface, and its overall area is more than 16 square meters.

Compared with ordinary planting and breeding, the original four square meters can only be planted with four square meters of grass, but four square meters can be planted with sixteen square meters of grass.

Space is used with a staggering four times as much efficiency.

In addition to this, the evaporation rate of water is directly proportional to the contact area of sunlight and the contact area of wind, and the smaller the contact area, the slower the evaporation rate.

The hill pack also has an extremely strong water storage effect, which can provide the most abundant water source for farming.

Like small mountains lying on the ground, they will concentrate the water that was originally spread on the flat surface like a mountain, so that they can meet and store together, reducing the contact area with wind and sunlight. (Water flows downward)

As a result, the evaporation rate of water is slower.

Abundant water sources, one plot of land can be used as four plots, or even six or seven plots of land, plus the characteristics of cultivating high-yield pasture.

The rules of farming are in line with almost all flat terrains, so that the arid grasslands, Gobi and deserts can be slowly turned into grain production bases.

That's not all the good things about the rules of the mountains and rivers.

The rules of the Principle of Mountains and Rivers are also a powerful defense system.

The four-sided hill bags that stand on the ground are more than one meter high, or even two or three meters high, and if the army dodges inside, it is basically immune to long-range attacks from the outside.

They can also shoot bows and arrows from inside the 40 hills.

If the other party wants to kill in, because of the barrier of the hill bag of the Sirangtai platform, there is no way to line up and walk.

Only after the Quadrangular Hill Bag has been cleared can this line be formed.

But that cleaning time, it takes very, very long, and the casualties are very large.

After all, it is impossible for the defenders inside the Quadrangular Hill to watch them clear their defenses, and they will inevitably harass them.

In addition, the forces that own the Quadrangular Hill Pack usually dig some tunnels and shooting holes.

It's completely impregnable.

It is not easy to get in with a gun, because in the irregular Quadrangular Mountain Pack, when both sides see each other, they can hide behind the Quadrangular Hill Pack and be immune to ranged attacks.

And when the two sides can see each other face to face, the distance between the two sides is generally only one or two meters, and the distance at this point may not be able to carry a knife with a gun.

The heaviest thing was that there was no way for the guns in the rear to provide large-scale support, because they could only march through the narrow passage between the narrow Quadrangular Hill Pack and the Quadrangular Hill Pack.

It is difficult to support each other, and there can only be a fierce melee in the narrowest passages.

The enemy also had to guard against a sneak attack by the defenders inside the tunnel.

Strong farming ability, strong defense and counterattack ability.

The rules of the Principle of Mountains and Rivers once made countless war geniuses in the Jingya world at a loss, and without using their extraordinary abilities to launch a flood, they could only use their flesh and blood to clean up the enemies inside step by step.

Usually they lose 2,000 of their own and 800 of their enemies.

Pabukar, the kobold, after a busy day, sat on a two-meter-high quadrangular hill and watched the sun slowly set over the high mountains in the distance.

Pointing to his newborn son, he pointed to the sun in the sky and said, "Your Majesty has said that he will lead us to occupy endless territories until all the territories that the sun can shine on." ”

"Your Majesty's goal is our goal, to look at the sun on the horizon, to see all the earth and sea that the sun can shine on."

"That's where you're going."

The little kobold looked at the slowly descending sun in the sky and nodded inexplicably.

However, there is one sentence he understands, the earth and the sea that the sun can shine on are His Majesty's territory, and he will use the knife in his hand to snatch it for His Majesty.

As for how many kobolds will die in this process, and how many intelligent beings will die, he doesn't know, and he doesn't need to know.

……

In the middle of the mountains.

Riding the unicorn elf king's long sword, he swung forward and said in a loud voice, "Speed up and move forward." ”

"Strive to arrive in the Black Dragon Basin this evening, and fight to the death with the Black Dragon Monarch tomorrow."

The mighty, exquisitely clad elven legion of elves sped up their speed the moment they heard the elven king's order.

In the high mountains, they could already see the large Black Dragon Basin in the distance at this time.

The dense quadrangular hill bag is really not too conspicuous.

At the speed at which they were traveling, they would be there by evening.

Night falls, and the cold moonlight illuminates the land.

Countless elven armies have encamped in the mountains near the Black Dragon Basin.

The sky-high flames covered the sky and almost completely covered the mountains and rivers to the west of the Black Dragon Basin.

An army of 300,000 elven elite forwards was pouring out of the mountains and rivers behind.

The fire is getting brighter and brighter.

Countless dark creatures in the Black Dragon Basin, looking at the flames rising into the sky in the distance, they couldn't help but clench their weapons one by one, full of bloodthirsty killing intent!

It's just that every time they come back to reality.

The male dark creature looked at his skin and bones that had not yet been raised, and the female dark creature looked at her already big belly, and one by one she held back the battle intent in her heart.

With their steel crossbows and arrows on their backs, they climbed into the tunnels in the quadrangular hill bag, and one by one they lay in ambush in front of the shooting holes in the countless quadrangular hill bags, ready to sneak attack at all times.

It's not that they don't want to fight the elves head-on.

Fight the various dark creatures of their seven clans, even if they are small cubs, then there is nothing to be afraid of.

Isn't it just a white knife in and a red knife out?

Who's afraid of whom?

It's just that they are now weaker and weaker one by one.

The males are squeezed dry, and they are all skinny and bones, and their strength is not even the usual one, and they fight with knives head-on, that is, they give away heads.

】

The morale is high, and sometimes you can't eat it as a meal, and you have to be cowardly when it's time to coax.

Not to mention the females, all of them are pregnant women, and the pregnant women are willing to go out and fight for knives, and none of Ace and all the transcendents and male dark creatures agree.

They haven't died yet, how can they let pregnant women go to the battlefield to fight for knives?

If this news is allowed to spread, he Ace will not be the master of the world, will he be ashamed?

The elves and the creatures of darkness looked at each other from across a mountain.

The creatures of darkness look at the light of fire, and they know that every piece of fire is a mass of elves, their enemies.

And the elves looked at the countless pitch-black quadrangular hills in the Black Dragon Basin.

They have also encountered the four-sided hill bag, and every time they have touched their heads, they need to pay a very big price to win the war.

Not far from their territory, on the edge of the mountain, there is a grassland of more than 100,000 square kilometers, in which hundreds of grassland elf tribes live, with a population of more than 10 million.

Relying on the small hill of the Silengtai platform, the hundreds of grassland elf tribes lived quite nourishingly, and from time to time they rushed out of the grassland to rob the surrounding forces, and they were also one of the targets of the attack.

The difficulty of the quadrangular hill bag, they are quite clear.

But now, they have no choice.

They are now taking advantage of the weakest time in the Black Dragon Realm to enter each other's territory.

Losing this opportunity, once the other party relaxes, they will definitely lose.

The aggressiveness of the Black Dragon Monarch, as well as their brutal and murderous character, once they are defeated, death is almost doomed.

Even elven children are not exempt from death.

For the sake of the continuation of the race, in this battle, either the other party dies or they die.

Among the splendid castle halls.

Ace Manor sat on his golden throne, the scarlet dragon's eye was shining, and the boiling murderous aura surrounded him, making all the dark legends and dark scholars who faced him bow their heads deeply.

Under the golden throne, seven dark legends and twenty-three dark scholars stood silently.

At this time, the castle hall was quiet, and the sound of needles falling to the ground could be heard.

Four hourglass hours have passed.

In the middle of the moon, half of the night has passed.

The gate of the castle was slowly opened under the gaze of five hundred dark nobles outside.

A dark nobleman who came running on a horse from the outside world dismounted as fast as he could, came to the center of the castle hall and knelt down on one knee and said, "Your Majesty, according to my investigation, there are only 300,000 elven legions in our eastern mountains now. ”

"It's the vanguard of the elves."

"They still have an army of 900,000 behind them, and they are coming in a steady stream."

"It's expected to be all there tomorrow by noon."

With that, the dark nobles exited the castle hall with a wave of Ace's hand.

The five-meter-high gate was re-closed.

The kobold scholar stepped forward and said, "Your Majesty, now the army of the elves has come to the city. ”

"As long as we stick to the principle of mountains and rivers, the four-sided platform and small hill package defense system brought by the farming rules."

"We're going to be able to defend it."

"The soldiers have dug endless tunnels, and dense shooting holes are all over every corner of the Black Dragon Basin."

"Under the steel crossbow shot, even if our warriors are a group of old, weak, sick and disabled, they can still firmly resist the attack of the elves."

"The only thing to guard against is their transcendent raid."

"However, our number of transcendents is not less than theirs, and the number of low-level transcendents below the legendary level is even greater than that of the elves."

"The legend is just one less than the other party."

"The elves simply can't break through our defenses."

Kobold scholars are quite confident.

Fighting in formation, the group of old, weak, sick and disabled under their command could not defeat the 1.2 million elven army on the opposite side, even if they doubled.

But if you defend in the defense system of the Quadrangular Hill Pack, it is absolutely no problem to exchange one for one.

They had three million dark soldiers, a million dark cubs who could pick up knives, and a million dark cubs who could pick up knives in another four or five months.

One for one, they are definitely making a lot of money, and they can exchange that group of elites for death.

Ace was relieved to see that the kobold scholar was so confident.

With a group of squeezed soft-footed shrimp, a bunch of pregnant women, and a group of underage cubs, a total of four million old, weak, sick and disabled troops, a total of 1.2 million elite elven soldiers who looked at death as if they were home.

That's a great way to think of him.

He could hardly find any way to win except for Kaihang.

Fortunately, the rules of farming are themselves open-ended.

Strong farming ability, strong defense ability, even if a group of old, weak, sick and disabled people are guarding, it is still an iron wall.

Not to mention, he also shaped the industrial system, and the super blood supply brought by the powerful industrial system allowed him to forge a large number of long-range weapon steel crossbows in a very short period of time.

The steel crossbow is comparable to a rifle at short and medium range.

In short, the advantage is mine.

Survive two months and see how he slaughters those elves.

The world master of his dignified crystal world, who had just come to the earth to establish his own black dragon kingdom, was seized by a group of weak elves and forced to abandon ninety percent of his territory.

Those who were also beaten by the other party could only dare not go out to fight in the field in the small hill of the Sirangtai and were passively beaten.

He could guarantee that if his sister Elena knew what was going on with him, she would laugh and roll around the ground dozens of times and laugh at him madly.

Seeing that His Majesty the Black Dragon Sovereign's face had become much better.

The Bat University scholar stepped forward and suggested, "Your Majesty, on the other side of the mountain, there are a large number of tribes of wild dark races. ”

"I suggest we contact them and get them to be under your dragon's wing."

"I believe that as long as they know that there is an opportunity to take refuge under your dragon wing, they will definitely come with the army desperately."

"There are a lot of them, they should add up to a million troops, three legends."

"As soon as they arrive, they will fight with us in two months, and the elves will definitely be defeated."

Bat University scholars are dripping blood in their hearts.

Then all he meows is military feats, but now in order to make up for their mistakes, they can only let them take refuge.

Suddenly there was a million less military merits, and he was distressed.
