Finding the source is something that is both simple and complex.

Thousands of years have passed, and no one knows what happened back then.

"Even emperors are not thorough in everything and have many doubts. This person who slaughtered an entire city seems to be a big shot, but we don't know what he was doing at the time."

Han Yunluo was also in a dilemma.

"Yes, unless we can go back in time, we simply can't do it."

Han Yunluo and Jiang Si lay on the sofa, looking up at the ceiling.

Qi Yan and She Zhang were quite shocked to see the two of them dressed like that as soon as they entered the room.

Jiang Si was somewhat unconventional, but Han Yunluo, being from a prestigious family, always maintained a proper posture and rarely acted this way.

"What's wrong with you?" She Zhang asked.

She Zhang has been in a good mood lately.

After becoming familiar with the Dream God, he not only gave him some cultivation techniques, but also imparted to him a great demon's cultivation experience.

Shezhang today may not be a great demon, but it is incomparable to what it used to be.

Similarly, Qi Yan's fire is now so pure that burning one or two demons wouldn't be a problem.

"I was thinking about time travel," Jiang Si replied.

Qi Yan poured cold water on the idea: "How is that possible? You need the Time Wheel."

Jiang Si rolled her eyes. "I know I'm grateful, you don't need to remind me."

The Time-Space Wheel is in the sky. Even if it weren't, the Upper Realm probably wouldn't lend it to him.

Sometimes, even God can be quite selfish.

It is said that mortals are like ants, and who would care about the life and death of ants?

Qi Yan has a flat mouth.

Han Yunluo comforted him, "We're just a little upset."

She Zhang asked, "Why do we suddenly need this Time Wheel?"

Jiang Si told them everything in detail.

Qi Yan said, "Even if Bihaitian escaped, he might not necessarily come to the human world."

If they're not in this world, how can they find them?

“That’s right,” She Zhang chimed in. “Judging from this man, he slaughtered the people of one city but not others. That means he was fair in his actions and didn’t harm others.”

"This usually means they have a deep-seated hatred for the people of that city. What's so strange about killing an entire city?" Qi Yan, after all, wasn't human and was somewhat indifferent to human life and death. "If that's really the case, his enemies have already reincarnated hundreds of times. How could he possibly find them?"

"He's not an idiot, is he going to do something wrong and get arrested again?"

Qi Yan and She Zhang, being demons, thought about it from a demon's perspective.

Jiang Si was almost convinced.

"You've all got me all confused," Jiang Si said. She was a human being and thought things through. For her, revenge wasn't just about this life; she wouldn't let it go in the next either.

What's wrong with suffering the consequences of mistakes made in this life in the next?

"If he really wanted some peace and quiet, why did he have to run away?" Jiang Si never thought so highly of people. She didn't fight unprepared battles, nor did she want to just drift along.

Han Yunluo said, "No matter how selfish we are, we have to find him first."

Whether he will commit further evil is another matter, but we can't leave a time bomb in the human world.

Given his methods, if he harbored evil intentions, with today's technology, he could easily slaughter not only a city, but an entire country.

They would never allow such a thing to happen.

Thinking about it, it's still so difficult.

Jiang Si and Han Yunluo both leaned back and lay down on the sofa again.

She Zhang and Qi Yan made the same gesture.

They are not very compassionate towards humans, but Jiang Si and Han Yunluo are the most important people to them, so they can't just stay out of it.

“It’s really impossible to go back in time to investigate,” She Zhang said slowly.

"I wish I could take a look," Qi Yan sighed.

She Zhang suddenly stood up, looking intently at Qi Yan.

Qi Yan: "W-what's wrong?" Completely bewildered by this sudden question, Qi Yan asked, "Did I say something wrong?"

“No, you’re not wrong, you’re absolutely right,” She Zhang said.

"Traveling back in time is definitely impossible, but it's not impossible for us to see what happened in the past."

Han Yunluo and Jiang Si both looked at She Zhang, their expressions suggesting that he should speak first.

After thinking for a moment, She Zhang said cautiously, "The Dream God comes from the past and lives by relying on people's dreams. So he must have entered the dream of someone in that time and space. In this way, we might be able to see things that happened in the past."

Jiang Si and Han Yunluo remained frozen in place for a long time.

Jiang Si patted She Zhang on the shoulder: "Not bad, I haven't spoiled you for nothing."

She Zhang yelled, "Can Jiang Si control her strength? If she weren't a demon, her hand would have been broken."

“And you,” Jiang Si looked at Qi Yan, her hand still in mid-air before Qi Yan quickly rolled away.

His small frame couldn't withstand a slap from Jiang Si.

Jiang Si immediately asked She Zhang to ask the Dream God for help.

The God of Dreams is quite righteous.

After hearing Jiang Si's words, he fell into a brief silence. "You mean Bihaitian?"

"You know him?" Jiang Si was overjoyed.

If you know them, things will be much easier; they must know what happened back then.

“Of course I know him, I’ve even been in his dreams.” The Dream God looked a little embarrassed. “But if you want to untie the knot, you have to untie the knot yourself. It’s better to give up as soon as possible.”

"Why?" Jiang Si asked.

"It was wrong of him to massacre a city back then, but the people of that city were not innocent. From Bihaitian's point of view, they even deserved to die."

Bihaitian was quite powerful back then. He not only killed all the people in the city, but also changed their fates, causing them to be reborn as animals for ten lifetimes.

The methods were extremely cruel.

The God of Dreams is a god with strong principles.

He was born with the ability to enter the dreams of all the gods, Buddhas, and sentient beings in the human realm, treating them all equally without showing favoritism to anyone.

Therefore, he would not blindly sympathize with ordinary people who had no power over their land.

The Dream God sighed, "To avoid bias, let you see for yourselves."

The Dream God can both enter dreams and create dreams.

It would be a piece of cake to weave a dream for Jiang Si and Han Yunluo.

When Jiang Si and Han Yunluo opened their eyes again, they were greeted by a scene from thousands of years ago, with countless people passing by them.

The people all looked hurried and ran in one direction.

They are dreamers, destined to be mere observers.

Jiang Si and Han Yunluo exchanged a glance and then ran over.

That was an execution ground.

On the execution ground stood a middle-aged man in tattered clothes, his eyes bloodshot, glaring at the crowd below with a deep-seated hatred in them.

He glanced at them one by one, as if trying to imprint them in his mind once more, so that he could take revenge in the future.

As noon approached, the executioner, dressed in his official robes, arrived at the execution ground.

“Bihaitian, you have colluded with evil spirits and deserve to die. You are sentenced to beheading.”

Bihaitian chuckled, his laughter chillingly eerie. "If I die today, I will drag you all into hell, where you will never have a good end in any future life."
