A large amount of waste energy and nutrients, as humans discharge day after day, enter the sewer and then enrich in the soil.

People all know that below the second floor of the sewer is a paradise for various huge creatures, which is very dangerous, but no one has ever thought about how these terrifying and dangerous huge creatures appeared.

In the sewage hole on the fourth floor, the turbulent water flow and the overly humid environment have turned this place into a paradise for slimes. Thirty years of calm environment without anyone disturbing them have made their bodies bigger and stronger.

However, no matter how strong the slime is, it is just a slime. It has no wisdom, no mind, simple division and straightforwardness. It is inherited from bloodline, which inhibits reproduction and ensures the safety of the population, so that their populations are huge but not bloated, just outside the door formed by the insect thinking - although that door is already close.

One day, the tranquility of the fourth level was broken.

Huge alchemy equipment was erected on the third floor, and a large amount of surplus, untreated magic energy spread everywhere frantically. The slimes on the fourth floor finally gained a new life.

The original size became larger, and the originally poor, limited resources that were not enough to support more populations coexist suddenly seemed endless!

Breeding, breeding! Missing this opportunity, I don’t know when I will wait for the next time!

So, when the total number of ethnic groups increased explosively, a red slime was quietly born.

It turns out that magic energy can be created.

It turns out that those upright creatures with ugly four claws are fragile and edible.

It turns out that we can get everything we need by expanding!

This is not enough, it must be bigger, more, and stronger!

Becoming bigger, more and more, stronger!

The slime grew bigger and bigger until it filled the entire fourth layer. The nutrient-rich sewage poured from the third layer became its daily delicacy.

It doesn't need to move, just open your mouth and wait.

In just over ten days, its spine merged with the dome of the fourth floor, its lower abdomen merged with the floor, the opening at the front end of the digestive tract and the step between the third and fourth floors, and its excretion pipe became the outlet connecting the sea hole.

Sewage enters from the front end of the digestive tube and pours out from the drain tube.

Magic energy, magic energy is not enough! More magic energy!

The blood vessels grow rapidly like roots hidden in the soil, extending rapidly, drilling through the permeability layer of seventeen meters, spreading across every corner between the third and fourth layers. One of them unexpectedly touched the shallow buried return line.

It has become stronger, it is the king of the sewer and a god! And at this moment, the scum that dares to offend it appears.

Destroy them! This is my territory!

At this time, the scum is also calculating it.

Team 1643 has escaped from the initial shock.

Dark asked first, "George, do you have any plans?"

"It's very simple. Slime is afraid of salt. There is endless salt around me!"

"Fill it with sea water? Smart!"

Reus said: "But what if this guy goes crazy and attacks the third floor like crazy?"

The psychic rattles and spit out another piece of paper.

George said: "Look, now it has stuffed the entire fourth layer, which is a slightly lower basin structure. I have heavy excavators on hand and there are twelve units behind it. I start from a distance from the sewage outlet and dig a 'u'-shaped pipe that wraps the entire basin. When you are ready, I will dig the pipe, start from its head with sea water, and squeeze it into the sea!"

Riley said anxiously: "But! The vibration caused by heavy machinery is too great! Once it is discovered..."

"I have several shock wave generators here, put it near the sea cave, and try to make my digging action look like the vibration caused by a deep earthquake. It dares not go into the water, and my only risk is the excavation process."

"But that's also very dangerous!"

"The most dangerous thing is you, as the flower hat says, once it goes crazy, you must insist on keeping it firmly before the sea water surges!"

Reus said: "Can we retreat to the ground and defend?"

Dark and Isabella spoke in unison: "Absolutely not!"

"For, why?"

Isabella pointed to the huge sewage pipes around her and said, "Because these pipes are thick enough and flowing fast enough, the Slime cannot go upstream from the pipes; our defense line is just completely stuck in their land march routes. Once they reach the second floor, they have 10,000 ways to penetrate the surface!"

Dark added: "As long as there is a slime with wisdom slipping up, human history will be rewritten... No, humanity may have no history!"

"Squad 1643, the mission goal has changed! Stay there for humans!"

Dark asked loudly, “How long will we stay?”

"Two hours! Up to two hours! Notify Hamilton's guards immediately that the real war has begun!"

When Dark informed Stilwell and Morson about the news, unexpectedly, the two of them were not depressed, but rather high.

Stilwell laughed: "A slime as big as a tunnel? No matter how big it is, it is just a slime! You dark walkers may not know that for us, if we can kill an epic creature, it will definitely be the supreme glory! It is worth it!"

Mosen nodded and said, "Your offensive plan is very good. Next, we need to re-arrange the defense, and the original plan must be cancelled. What Egnathun desires most now is to break through our defense line and expand its power to the surface. Therefore, if it cannot conquer for a long time, it may find a way to bypass us."

"If it is so big, if it is drilling around, we cannot defend it. Why don't we give it some hope and strangle it to death when it goes all out!"

Isabella's eyes lit up: "Good idea! Let go of a road that seems to lead to the second level, but in fact it will never reach it, and let it bleed! "

Stilwell said: "The danger of doing this is that it will definitely hit the frontal assault if it backfired..."

"We only need to drag for two hours to set up blocking fronts in layers. I heard that bugs can drill into the ground, so the interval between the fronts should not be too long, so as not to be divided and surrounded by it."

"So, two hours later, there is sea water everywhere here, how can we escape?"

Isabella said: "There is an upward maintenance channel in the northwest corner, and we go up in batches."

"The last question, how do we declare war on that guy?"

Isabella smiled and said, "Our people are ready. With just one order, they will immediately make it crazy. So, two, when they are ready, tell me - is there any code for action?"

The two looked at each other and Stilwell said, "Since the specific plan was formulated by both of us, then let us leave the code name to you!"

"Well, then I'm not polite. I announce that the 'watering' operation has begun!"

Ten minutes later, Dark held a sharp double-edged battle axe in both hands and stood in front of the thick blood vessel disguised as a magic energy return line with a smirk.

The blood vessel twitched tightly!

Isabella's order came from the earplugs: "Do it!"

With a light crack, the blood vessel was chopped into two pieces by Dake with an axe!

The disguise is exposed and the decisive battle begins!
Chapter completed!
