The villains are redeemed, and the heroines cry and beg for forgiveness.

"That's all? No other instructions? Really?" Gu Ran asked, looking into Xue Xiling's eyes.

Xue Xiling originally wanted to say "no" directly, but under the pressure of Gu Ran's piercing gaze, she still thought about it seriously for a while.

"No...that's all, that's really all Dad said," Xue Xiling said weakly.

After careful consideration, she realized that she really had nothing more to say.

Seeing that he could get no more information, Gu Ran walked to a spot not far from the giant triangular pyramid building.

If you ask him to find something he's familiar with for comparison, it would be the pyramids.

This thing is like a cyber pyramid, with the shape of a pyramid and the technology of cyberpunk.

"As long as I get close, the gate to the ruins opens automatically. Is this ruin my home? Is it like coming home, so it opens the door for me automatically?" Gu Ran couldn't help but chuckle to himself.

To Gu Ran's surprise, the cyber pyramid actually reacted as he approached.

"The gates are open! The gates are open!"

A mechanical electronic voice came through.

The voice startled Gu Ran, and her heart surged with emotion.

The voice was so familiar; it was the same mechanical electronic voice from the Merfolk ruins.

Could it be that the two ruins were built by the same person or organization?

Gu Ran couldn't help but make some unfounded connections.

Or is it just a coincidence that all mechanical and electronic sounds in the world are the same?

However, no matter how he thought about it, Gu Ran still felt that the first guess was more reliable, because he had heard other similar mechanical electronic sounds before, which were quite different from this one.

"Welcome back!"

As a voice rang out, as if they had been transported to another world, Gu Ran and the others suddenly found that their surroundings had undergone a complete transformation.

The original wilderness has disappeared, replaced by a city.

This city...

Why does it look so familiar?

"Azure Dragon City? We're back in Azure Dragon City?" a voice exclaimed in surprise.

The others, alerted by the voice, also discovered that the city not far away was actually Canglong City.

Gu Ran had observed Canglong City from afar, and there was a phantom image of a blue dragon that left a deep impression on him. And now, that phantom image of a blue dragon had reappeared. It circled above Canglong City for a while, seemingly letting out a deafening roar, and then flew into Canglong City, seemingly merging with it.

This really is Azure Dragon City!?

Gu Ran was also stunned.

They actually went back?

"What's going on? Are we not going to explore the ruins anymore? Why are we back in Azure Dragon City?" someone asked, puzzled.

"How would I know what happened? You'll have to ask Team Leader Leng for the details."

Everyone turned their attention to Gu Ran.

Gu Ran checked his belongings and found nothing missing; the hard parts were still hard, and the soft parts were still soft.

"Let's go! No matter what, let's go to the Azure Dragon City we saw first." Gu Ran took the lead and headed towards the Azure Dragon City.

He has just ruled out the possibility that someone else cast an illusion on them, so they may really have gone back.

Although they didn't know why the ruins teleported them back, it was still a good thing that they were able to return safely, even if they didn't gain anything.

Oh, no, the ruins teleported them to a place not far from Azure Dragon City, which, in the spirit of scientific research, is itself a gain.

“Hey, look, how come the housing in those slums in front of Canglong City has changed so much? Did the ruling center of the inner city allocate funds to renovate this area? But why go to so much trouble to renovate it?” A researcher pointed curiously at the slums of Canglong City.

Gu Ran saw it too, and his expression became extremely solemn.

"Let's quicken our pace," Gu Ran instructed, turning his head.

The team's speed immediately increased significantly, and twenty minutes later, they arrived at the outskirts of the slums of Canglong City.

"The buildings here look like they're from hundreds of years ago," one researcher remarked, puzzled.

"Can you specify which era?" Gu Ran immediately turned to look at him.

The researcher was startled by Gu Ran's serious expression. After thinking for a moment, he said, "It should be a building from four hundred to three hundred years ago. At that time, the city defense cannons had not yet been invented, and even Star Stone Technology was just starting out."

"Therefore, the buildings in these slums were built like fortresses, mainly to better defend against the attack of the beast tide. However, if you look closely, you can see some Star Stone technology products such as wires on these buildings, which means that Star Stone technology should have started at this time. The most suitable period is from four hundred years ago to three hundred years ago."

Gu Ran's face darkened slightly.

This period of time... refers to the era of the infamous, yet largely unknown, tyrant of Canglong City.

Did they travel back in time?

But time should be linear and irreversible.

Or is this some kind of illusion?

Gu Ran blended into her surroundings, quietly absorbing the atmosphere.

However, the result of my experience was that this was a normal world, not some kind of illusion or trick.

"Look, that's a horde of ferocious beasts!"

Suddenly someone pointed to the distant wilderness and shouted in panic.

In the far distance, a vast darkness descended, encompassing countless ferocious beasts.

If they were in the inner city, they certainly wouldn't be so panicked, but they weren't in the inner city at the moment, and the Azure Dragon City in front of them was very strange, completely different from the Azure Dragon City they knew.

140. Another battle to defend Azure Dragon City against a beast tide! (4k)

No one expected to encounter a horde of ferocious beasts at this time. Now they were truly caught between a rock and a hard place, unable to advance or retreat.

If they retreated into Canglong City to avoid the beast tide, the situation inside the city was unclear, and they still had great doubts about this Canglong City that was both familiar and unfamiliar. If they did not retreat into Canglong City, they would have to face the beast tide that was about to arrive.

Moreover, judging from the situation, this beast tide covers a very wide area, and even if they want to retreat in the original direction, they still cannot escape the beast tide.

Although they had all practiced martial arts to some extent, it only helped them improve their physical fitness. At most, they could kill a dozen or so ordinary ferocious beasts with firearms. Once they ran out of bullets, it would be their time to die.

Everyone couldn't help but turn their attention to Gu Ran.

"We'll retreat into Canglong City, but not too deep. Let's find a place to hide and observe the situation first," Gu Ran said calmly.

Since the true state of this world is still unclear, Gu Ran chose a compromise.

Upon hearing Gu Ran's words, everyone quickly ran towards the slums.

“It seems there are residents here too! Look, they’re all hiding inside their houses watching us.”

Indeed, many pairs of eyes could be seen peering into these fortified buildings, and human figures could be faintly seen in the distance. However, they were all silent and made no attempt to help or attack Gu Ran and his companions who were running through the streets.

"Everything here looks like it's from hundreds of years ago. Could we have really traveled back to Azure Dragon City from hundreds of years ago?"

Along the way, everything they saw was quite different from the Azure Dragon City they knew.

The Azure Dragon City they knew was now a place where martial arts flourished, even in the slums. When faced with a horde of ferocious beasts, everyone except the elderly, women, and children would actively fight the beasts to earn military merits.

Because they can rely on their own strength and that of their legion to resist the beast tide, they will even take the initiative to attack. Therefore, the buildings in the slums are just ordinary buildings. Only in the back part of the slums are some fortified buildings built for the elderly, weak, women and children to hide.

Now, the slums of Canglong City are practically lined with fortresses. Behind every one or two ordinary houses is an armed fortress with parapets, arrow slits, and some devices of unknown purpose.

"Okay, let's stop!"

When they arrived at the Dragon Blood River, Gu Ran called out to everyone to stop.

Since there was no road ahead, they would have to swim across if they wanted to cross the river.

"A detachable and reassembleable pontoon bridge... and it's already been packed away." Gu Ran looked at the pile of pontoon bridge materials placed to the side on the other side, with some soldiers guarding it.

When Gu Ran and his strange group arrived, all the soldiers turned to look at them with a hint of wariness in their eyes.

"Such a reaction is really realistic. Is there any illusion that can achieve this right now?"

After thinking it over, Gu Ran temporarily ruled out the possibility of encountering an illusion.

Suddenly, Gu Ran felt the triangular crystal cone in his pocket start to stir, and he really wanted to fly towards the Dragon Blood River.

Gu Ran's expression changed slightly.

The last time it acted strangely by the Dragon Blood River was because the triangular crystal cone wanted to absorb something from the Dragon Blood River, but it should have finished absorbing it by then, so why is it thirsty again now?

Could it be that this river, the river in front of him, still contains that thing that the triangular crystal cone longs for?

If that's really the case, doesn't that mean the river is actually real?

Have we really traveled back more than 300 years?

But time is linear and irreversible...

Throughout human history, no one has ever been able to control the power to reverse time. Countless people have been fascinated by this topic, but let alone the power to reverse time, there are very few powers that are even remotely related to time, let alone the power to alter space and time like this.

"Could it be that the power of this ruin is so great?" Gu Ran couldn't help but wonder.

Although records show that humans have never possessed any power to reverse time, it is possible that such a power does exist, but has not yet been recorded by humans.

Furthermore, the records concerning this tyrant are vague and incomplete...
