The capture of the advance base means that the rat clan has gained an overwhelming strategic advantage over the snake demon.

In the days that followed, the Rat sent out a large number of scouts to scout every crevice in the rock within a radius of miles, looking for insect tides and snake demon nests based on wet traces, faded insect shells, and gnawed away glow-in-the-dark plant roots.

Thousands of insects and snakes crawled, it was impossible not to leave clues, and soon, the scope of the snake demon's lair was constantly reduced, and the traffic arteries leading from the snake demon's lair to the insect nest were also cut off.

The national division also sent engineering rat soldiers similar to "pangolins" to dig all the way, opening up more than a dozen thoroughfares from the rear to the front line, so that materials and troops could be continuously transported.

Finally, on the fourth day after seizing the advance base, they found the habitat of the underground snakes in Lingshan City.

This was originally the largest landfill in the "Old Spirit Mountain".

The garbage discarded by countless human beings has long been buried deep in the ground, turning into a treasure trove of snakes, insects, rats and ants.

Moreover, after the revival of the aura, countless highly evolved demons and monsters were born, and the ghosts and ghosts were born.

As far as the eye can see, the rocks are crisp gray-white, covered with holes, like hornet's nests.

In the depths of the cave, there is a strange purple fire flickering from time to time, which is the light flame that is stirred up after decades of fermentation of underground garbage, releasing a large number of flammable and explosive gases.

On the rugged ground, there is a layer of slimy and foul-smelling humus, which is extremely deep and thick, and when the rat people step into it, half of their bodies are often submerged, even if they struggle to jump out, their limbs will be glued and they can't move.

On the contrary, the snake tribe, with its smooth scales and special crawling posture, can move flexibly on these slimy humus, as if walking on the ground.

And the lithe beetles and arthropods, such as spiders and centipedes, can also dance on the humus, dancing to the melody of death.

The snake demon has long known that the rat civilization is coming to the city.

Countless snake heads and colorful poisonous insects all poked their heads out of the crevices of the beehive-like rocks, staring at the army with mysterious expressions.

However, when the rats tried to crawl through the slimy humus to catch them, they quickly burrowed deep into the crevasses and disappeared.

The national teacher simply ignored these small groups of harassment and scouts, and ordered the large army to deploy, and directly destroyed the snake demon's lair in a devastating manner.

Or a three-plank axe - first of all, the deeply brainwashed "berserkers", bundled grenades and all kinds of flammable and explosive materials, rushed to the deepest part of the enemy's "position", and blew themselves and everything that stood in their way to pieces.

Shotguns, automatic rifles, and fireworks and firecrackers of all kinds rained down on the heads of the insects and snakes in an almost profligate manner, completely drowning the enemy with the most brilliant flames of destruction.

Then, it is the muddy rats, the rat tribes of the vassal tribes, and the slave soldiers of the Fang Kingdom itself to form a "cannon fodder army", forming an overwhelming rat tide, rushing forward with a momentum like a bamboo, devouring everything, to destroy those insects and snakes that have been blown up to the ground and burned out of the body, even if they can't destroy the opponent, at least they can use their own lives to dull the opponent's minions and consume the opponent's energy.

In the end, it was the regular army of the Long Fang Kingdom, including the Cat Eaters, Golden Tails, and the warriors of the "Four Families", who gathered into a neat phalanx and crushed all the way with a dignified attitude.

In the past few days of contact, such a "three-plate axe" was originally invincible.

But in the lair of the snake demon, he encountered great trouble.

The main thing is that around this battlefield, there is garbage piled up for decades, and there is extremely dangerous biogas everywhere.

I don't know whether the rock formation here is just on top of the fault, or if it has been infected by the aura, the internal structure has changed, and it has become shattered at the touch of a button, which is very easy to trigger a chain reaction and collapse completely.

As a result, the explosion of a rat grenade or a small firecracker in the depths of the battlefield is very likely to detonate the methane gas or ignite the flammable material that has accumulated for decades and is about to ferment.

The former unleashes a devastating shockwave that indiscriminately kills all creatures within the blast radius.

The latter creates a flaming wall of fire, dividing the battlefield into small and fragmented squares, making it impossible for either side to assemble troops, let alone command effectively.

When you're unlucky, the shotgun can even trigger an avalanche-like chain reaction, and the large rock wall and the garbage on it roll down like a mudslide, and no matter whether the rats, snakes, or insects are buried inside, there is no hope of escape.

Not to mention the slimy humus itself, it has brought great trouble to the rat clan, making them seem to be tied up to fight the enemy, even if they have a thousand catties of strength, they can't exert fifty percent.

This is the worst battleground.

But the decisive battle has already broken out, and there is absolutely no reason to give up halfway.

The national teacher could only stare at the scarlet eyes, held one festival after another, and sent one overseer team after another, half coercing, half tempting to order the leaders of the vassal tribes to press all their strength, along with themselves.

"The gods are watching us!"

The national teacher roared hoarsely, "The gods are everywhere, watching each of our performances, when our flesh and blood are turned to dust in this dark and rancid hell, our heroic spirits will see an incomparably brilliant rainbow bridge, and cross the rainbow bridge to heaven under the blue sky and white clouds!" ”

"Boom!"

As if to confirm its words, an earth-shattering biogas explosion broke out on the front line again, raging flames rose into the sky, and countless torn corpses of the rat clan were turned into powder in the flames.

"Kill!"

Before the flames were extinguished, the remaining rat cannon fodder stepped on the burnt humus and rushed to the depths of the snake demon's lair.

In this barbaric war against madness, it was the madness with a firmer belief that won a temporary victory.

After leaving the corpses everywhere, the insects and snakes disappeared from the beehive-like crevices without a trace, and the surrounding area became dead silence again.

The rats cheered and took the opportunity to occupy a large part of the battlefield.

At this time, the consumption of cannon fodder by the rat clan itself is also very serious - rats are originally the inexhaustible, cheapest thing in the underground world, but how to quickly and massively transport cannon fodder to the front line is also a problem that tests the commander's ability.

The old cannon fodder was almost dead and wounded, and the new cannon fodder didn't have time to accept the "brainwashing" and be transported to the front line for a while, but the national teacher was unwilling to leave a respite for the snake demon, so he could only order the elite regular army of the Long Fang Kingdom to continue to advance.

The further you go, the narrower the crevices, the rougher the road, the deeper the humus beneath your feet, and the stronger the stench of garbage.

There is no need for Chu Ge and Bai Ye's "smart heads" at all, even the cat eaters and Golden Tail realize that they seem to have fallen into a dilemma.

Although the snake demons voluntarily withdrew from the battlefield and handed over the precious garbage dump, in such a short period of time, they were unable to effectively use the resources in the landfill, and instead had to disperse a large number of troops and fall into this unfamiliar foreign land.

And the further they went, the more they fell into the rhythm of the snake demon, and were even led by the nose into a trap without knowing anything.

"It can't go on like this."

On behalf of the Cat Eater, Chu Ge found Bai Ye and said, "Our team is too scattered, and we don't know where the main force of the Snake Demon and itself are hiding, if the Snake Demon has a way to detonate the methane gas in the entire landfill, our entire army will be wiped out!" ”

Although Chu Ge and Bai Ye were both suspicious of the National Teacher's motives, they were also very clear that any suspicions could not be verified until the Snake Demon was defeated.

The national teacher can use the Rat army as a pawn, but Chu Ge and Bai Ye, who are in it, have to think about the life and death of themselves and their "compatriots".

They, including generals such as Golden Tail, who also had a keen sense of smell, stopped one after another, unwilling to move on.

But they had already stepped into the trap of the snake demon, and hundreds of spikes suddenly emerged from the depths of the sticky and foul-smelling humus, piercing the internal organs of hundreds of rat clans at once, and in the terrible scream, it was announced that the snake demon's most fierce counterattack had come!
