Rosen then spent a few hours flipping through the books here, comparing the Chaos Calamities of all the ages.

He found that the most serious disaster of chaos should be 1,200 years ago, if it is replaced by surface time, it should be 40 years ago, most of the Forgotten City was cleaned by black monsters, and the population here has also plummeted to one-tenth, if it were not for the black monsters breaking through to the fifth layer, causing many explorers to enter here unexpectedly, then it is very likely that the inhabitants of the Forgotten City would be completely wiped out.

But Rosen also found that most of the harm of the Chaos Scourge is related to scale.

The more harmful Chaos Scourge is actually that there are more black monsters coming out of the black mud, and the less harmful ones are fewer black monsters coming out, but the strength of the black monsters seems to have not changed over the years.

But it's normal to think about it, even if it was 1,200 years ago, the actual time was only forty years, and for the chaos monsters, it was only a blink of an eye, and it was difficult to change anything in intensity.

The history of the Forgotten City dates back more than 9,000 years, and although there are sacrifices every year, there are still occasional chaos disasters, which is one of the reasons why the population here is still small despite so many years of development.

The huge pressure of survival wears down the will of human beings, as long as they contribute a few insignificant lives, they can spend the next year in peace, and as a leader, they will naturally choose such a "peaceful" way.

Rosen also knows that the reason why he thinks that the people here are not enterprising is because he stands in the perspective of a bystander, if it is placed on the person concerned, the strength is not enough to fight against the black mud, no matter how he resists, it will lead to disaster, so for the sake of most of the clansmen, choosing to compromise is also a last resort, and such an idea does exist.

But Lawson wasn't going to stop like Sauron.

He flipped through the tomes, not only to learn about the history of the place, but also to assess the danger of the Chaos Calamity, so as to deduce the strength of that sludge.

If Rosen is not mistaken, the black mud should not be a citizen of chaos, but some kind of high-level chaos creation, as for the black monster, it is derived from the black mud.

As for why the black mud couldn't cause damage to the building, Rosen didn't know, but it wasn't something he needed to care about.

With most of the information out of the way, Rosen was ready to get started.

However, when he took Fina and Irandall to the vicinity of the central square of the city, where Black Mud was located, he found that Sauron was already standing there with several people.

"The demons on the ground are raging, and we have to go to the seventh layer to deal with the demon tide on the ground, which is the lives of hundreds of thousands of people. ”

Edlandall said, she could see that Sauron didn't want them to enter the black mud, but she was afraid of Rosen's strength, so she used this roundabout method.

"But if you enter the seventh layer, we who live in this city will be destroyed. ”

Sauron said calmly.

"And that sacrificing our people to fulfill the people of the earth is a nobler act?"

Alandel was speechless for a moment, Sauron's question was very real, sacrificing a few to save the majority is the choice of the ruler in most cases, but it is by no means the best choice, she looked at Rosen with some uneasiness, but this bone frame has no waves in her heart.

"Wait, Mr. Sauron, I think there's something wrong with your perception. ”

Lawson said, gently drawing the Wolf Knight's greatsword.

"Why do you think that after we enter the seventh layer, the black mud will still wreak havoc and cause calamity?"

"Y-What do you mean?"

Sauron's eyes widened in disbelief as he looked Rosen up and down.

"Impossible, in these thousands of years, no one has ever been able to successfully challenge the people of Chaos, you can't succeed. ”

"Get out of the way. ”

Rosen raised his sword and said to Sauron.

"You're going to kill us all!"

Sauron and the people around him tried to resist, but Rosen's powerful aura made them freeze in place, unable to move, as if someone was holding a sharp knife against their back.

Sauron broke out in a cold sweat, the armored knight in front of him was like a legendary evil spirit, exuding an extremely ominous aura, and he even had the illusion that the other party was emitting raging flames.

Step by step, they gradually got out of the way, no one dared to resist, even if it was the bronze Sauron, they could feel that Rosen's strength was not simply stronger or faster in strength, but some kind of power beyond the law, a barrier that he could not overcome in his life.

"Look closely, you people have been in awe of the black mud for tens of thousands of years, what the hell is it. ”

Rosen took a step forward, and the remaining ten yards of distance instantly turned to zero, and he appeared in the sky above the black mud, suspended in the air as if he were stepping on solid ground, and on the ancient sword in his hand, a pale blue flame ignited.

The Forgotten City, which had been a little dim under the light of fluorescent plants and torches, suddenly became bright.

At this moment, all the people here stopped what they were doing and turned their eyes to the long sword in Lawson's hand in the center of the city.

The pale blue flames, bright and dazzling, were like the sun that had only appeared in legends.

And the black mud seemed to sense something, and the originally calm surface began to ripple.

"It's coming, it's angry, we're all going to die!"

Sauron took a few steps back, looking in horror at the black mud that was gradually boiling, and the people around him were also trembling, almost falling to their knees, it was hard to imagine that this was the appearance of a bronze rank powerhouse.

He saw that Irandall and Fina were standing still, and tried to pull them apart.

"Run, there will be countless black monsters in a while, do you want to be torn to pieces!"

The next moment, countless black monsters were spit out of the black mud, these monsters did not have a unified appearance, multi-legged insects, winged birds, running beasts, and even humanoid creatures, they were all covered with black sludge, and were rushing around, looking for the breath of creatures.

But Elandall didn't look at Sauron, and she only whispered in the face of the black mud that was gradually emerging from monsters.

"I'm not going to go because I believe in him. ”

Between the words, Rosen's sword had been slashed.

With a sword, the light was dazzling, in stark contrast to the filthy black mud, and the blade of the sword fell straight down into the black mud, stirring up boundless waves.
