It's not just Tie Ruonan who is puzzled, but even Seventh Sister and Tie Niu are also puzzled.

After all, the time it takes to build Black Rock City is not overnight, and the effort is absolutely unimaginable.

So they glanced at each other and followed Qin Tianyu towards the location of the city wall.

Their appearance also attracted the attention of the people of Blackstone City.

After all, Qin Tianyu is the strongest person in the human race, and his appearance and behavior have attracted the attention of countless people.

Just like those superstars in previous lives, people more or less know what they look like.

Therefore, during Qin Tianyu's walking, many people silently watched, watching Qin Tianyu walk onto the steel wall.

"Lord Dragon Summoner, what are you going to do? It looks like something big is happening. ”

"Could it be that the beast tide is coming again?" Someone worried.

"It's impossible, the last time the beast tide suffered heavy casualties, if you want to recover, it's impossible to have a few years, and they don't dare to come."

"Yes, the Dragon Summoner is here, and they have only one result, and that is to seek death."

"What are you going to do, sir? It's weird. ”

"I know, I know, I have relatives who work in the government, and they've been busy with housing in the city lately, and the number of people has skyrocketed, probably because of that."

"It's... It seems difficult. ”

"What's more difficult? It's simply an unimaginably big project, and the teleportation array of the Demon Tower has been flickering, and people are constantly pouring into Black Rock City, and now the city is full of people. ”

The people who ate melons were talking one by one, curious about Qin Tianyu, but also feeling a headache for the increasing number of people.

It's a pity that they can't do anything about it, after all, the amount of work to build Black Rock City will be very, very unimaginable.

So they have nothing else to do but talk.

While these people were talking, Qin Tianyu had already come to the highest part of the city wall, and he looked at the desolate outside the city and smiled slightly.

Then he took out the steel treasure from the soul space, and threw it into the sky.

The next second.

"Boom!"

The terrifying city of steel suddenly bloomed in the sky, like a city in the sky, falling from the sky.

With a terrifying force like a black cloud crushing the city, it fell with a bang.

"Boom!"

The trembling of the earth's wrestling, and the loud sound that shook the sky echoed throughout Black Rock City, echoing in all directions.

When the entire human race in the city heard this tremor, they all came out of their homes and looked out in horror.

Watching the two steel cities link together, it has become two areas, the inner city and the outer city, and it is very perfectly linked together, weird and mysterious.

"Problem solved." Qin Tianyu glanced at the fused steel secret treasure, he clapped his hands, and walked towards the City Lord's Mansion with a smile.

The outer city, which had just appeared, was three times larger than the inner city.

Such a scale is enough to solve the problem of the number of people in Blackstone City.

As for the remaining housing allocation, it can be handed over to Tie Ruonan.

This woman is still very powerful, with the capital of a strong woman, plus the physique of a professional.

She worked for more than ten days without sleeping, and there was no problem at all.

So Qin Tianyu directly sat up and shook his hands at the shopkeeper.

******

The people around looked at Qin Tianyu, who was gradually leaving, and stood on the spot one by one as petrified.

They looked at the newly added steel outer city, and their eyes widened one by one when they thought of the big problem that Qin Tianyu had solved with a wave of his hand.

"Too... It's amazing, I didn't expect such a big problem to be solved by the Dragon Summoner in an instant. ”

"yes, I can't imagine it, it's really unpredictable."

"Sure enough, it's right to come to Black Rock City, only the city where the dragon summoner is located is the safest."

The surrounding crowd looked at the departing Qin Tianyu with awe and adoration, and they made up their minds in their hearts that they wanted to live here forever.

On the city wall in the distance, a little Lori-like little girl quietly looked at the departing Qin Tianyu, with a smile on her cute little face.

"It's really amazing, I will repay you for the favor, my Tong Tong never owes a favor, the next step is to take the position of the town guard general, become the number 1 there, and protect Black Rock City for you."

Little Lori smiled and muttered, a hint of determination flashing in her pure eyes.

********

Castle Lord's Mansion.

Qin Tianyu quietly listened to the seventh sister's story, and the surprise in his heart became stronger and stronger.

"Are you saying that the reason why the cataclysm happened in this world is because the demons broke the spatial rift and the demonic energy swept the entire world?" Qin Tianyu said in surprise.

"Yes, and the destruction of the Holy Clan was also because of the Demon Clan, and the enemy who invaded the Demon Tower at that time was the Demon Clan." The seventh sister said solemnly.

"How do you know that?" Qin Tianyu was puzzled, his eyes full of suspicion.

"Because I'm a demon!" The seventh sister said amazingly.

"Huh?"

Qin Tianyu stood up and stared straight at the seventh sister.

But he didn't take the next step, and the person who could honestly admit to him that he was a demon and tell everything he knew couldn't be so bad that no matter how bad he was.

"The demons live in the abyss, and there are countless races living in the abyss, including us abyssal humans, but we are still demons." The seventh sister said quietly.

"Why are you telling me this, aren't you afraid of being known and spurned by all people?" Qin Tianyu said.

"I'm afraid, but I still have to say that the demons always want to invade this world, and then seize the demon tower, and even destroy all the humans, for example, my task was to clean up all the saints." Seventh Sister said.

"Go on." Qin Tianyu said.

"After the destruction of the Holy Clansmen, there were still survivors, and I and another female demon clan were sent to Black Rock City to clean up the Holy Clansmen, but then I gave up." Seventh Sister said.

"There are actually Saints in Black Rock City?" Qin Tianyu said.

"That's right, it's your younger brothers and sisters Qin Feng and Qin Yue." Seventh Sister said.

"What?!"

This time Qin Tianyu was completely surprised, he didn't expect that the two little guys he adopted back then would have such an identity.

"Qin Yue was very beautiful and cute when she was a child, and her pure eyes made me unbearable to do it no matter what, and even if the female demon wanted to do it, I stopped it."

"Then I fell out with her, and in the end I killed her, but I was also seriously injured and unconscious, and then I was rescued by the Happy Mansion."

"However, Qin Yue, as a member of the Holy Clan, is still very dangerous, in this world, the Demon Clan hates the Holy Clan the most, so he often sends people to find the Holy Clan."

"Two years ago, there were two demons in Black Rock City, and I was going to stop them, but they died suddenly, which is very bizarre."

The seventh sister kept talking, telling everything she knew and what she doubted.

"Mysterious death?"

Qin Tianyu's sword frowned, he didn't expect that the place where he lived was so dangerous, and there were even demon people secretly peeping behind him.

"You and I tell me more about the situation of the demons, since the demons are from the abyss, is the abyss the kind of terrifying zone with infinite layers?" Qin Tianyu said suddenly.

"Huh? How do you know, my lord? ”

The seventh sister looked at Qin Tianyu in surprise, with a deep incredulity in her eyes.
