He touched the little witch's head, patted her gently, and said, "I'm here! If you feel tired outside in the future, come to me. I will be your relative from now on. You should know that although you are a powerful Spirit Emperor, I have always regarded you as my sister. Shouldn't you call me brother?"

The little witch immediately gave Gu Yuan a cold look and even wanted to use her spiritual energy to teach Gu Yuan a lesson.

Seeing Gu Yuan, she said, "You, a mere spirit master, still want to be my brother? That's impossible! If you really want to be my brother, work hard to improve your strength. When your strength surpasses mine one day, you can be my brother.

However, it is not so easy to surpass me. After all, as your cultivation level is increasing, mine is also increasing. So if you want to catch up with me, you will have to wait for a while.

But I will always wait for you. I will give you ten years. I wonder if you can catch up with me."

Gu Yuan looked at the little witch and laughed, then said, "Ten years? You actually think it will take me ten years to become a Spirit Emperor? You really underestimate me!"

The little witch raised an eyebrow, then looked at him in surprise and asked, "Do you think you can reach the realm of Spirit Emperor within ten years?"

Gu Yuan sneered, then looked at the little witch seriously and said, "I'm telling you, you really underestimated me. Don't even mention ten years. I can promise you five years. Within five years, I will be where you are now and become the Spirit King. Do you believe it?"

Seeing that Gu Yuan didn't seem to be joking at all, the little witch stared at him and asked, "Where do you get your confidence from? Your cultivation talent isn't even the strongest. Why do you think you can achieve Spirit Emperor status within five years?"

Gu Yuan smiled and replied, "I can't tell you that, but I can tell you this: trust me! Within five years, or even less than five years, I will be able to become a Spiritual Emperor. You can just watch and see. Don't ask me how I did it. You just need to see the results and see if I can achieve this goal within five years! I hope you won't be too surprised by then. Just be mentally prepared."

Seeing that Gu Yuan didn't look like he was joking at all, the little witch said, "Okay, didn't you say five years? If you can become a Spirit Emperor within five years, I don't need you to reach the level of a Level Five Spirit Emperor like I am now. You just need to become a Spirit Emperor within five years and enter the Spirit Emperor realm. Then I can promise you one thing. As long as it doesn't go against my wishes, I can agree to it."

Gu Yuan stared at the little witch and asked, "Are you serious?"

The little witch pointed to the sky and said, "Heaven is my witness."

This time, Gu Yuan was completely excited. Heaven was his witness. This was an oath made under Heaven, and no one could break it. If anyone broke it, they would be punished by Heaven. This was enough to show that the little witch was really serious.

Gu Yuan clapped his hands and said with a smile, "Okay! Five years from now, remember what you said now. When the time comes, don't refuse any request I make, or you will be punished."

"Okay, I'll wait for you. I'll give you five years and see how you become the Spirit King."

Along the way, the two of them had nothing to do and made this bet.

None of them knew what the outcome of this bet would be, but Gu Yuan had enough confidence in his heart. He felt that he could become the Soul King within five years. In other words, he would need to advance one realm a year. This seemed impossible to the little witch. After all, he was already at the Soul King realm, so it would be very difficult for him to advance to the next realm.

But Gu Yuan can be said to be a newborn calf that is not afraid of a tiger. He has enough confidence in himself. If he can't even become a Spirit Emperor, then how can he be worthy of the help the system has given him?

So this is also the source of Gu Yuan’s confidence. The system is his greatest reliance. If there is no system, he would never be able to say such words.

But with the existence of this heaven-defying plug-in system, Gu Yuan felt that everything was possible. The key was whether he was willing to work hard. As long as he worked hard, becoming a Spirit Emperor was not a dream at all.

Along the way, the little witch and Gu Yuan played and fought, and while they were rushing on the road looking for someone, they did not forget to appreciate the beautiful scenery along the way.

All in all, it was quite enjoyable for the two of them. After all, it would be rather boring to just work and look for people in this strange place, so the two of them could be said to be doing quite well, combining work and rest.

Along the way, the place we want to go now is Datucheng.

Datu City is also a very large city, and it is even more prosperous than Dashui City. What is more interesting is that they can see not only Dashui City and Datu City on the map, but also Damu City, Dajin City, Dahuo City and other cities.

They couldn't help but look at the map carefully and found that the five cities on it occupied the five directions of east, west, south, north and center.

The Fire City is located in the center of the city in four directions, and no one knows what its layout is.

However, in the opinion of the little witch, this should be a formation.

But what surprised her more was who on earth could actually arrange five super-large cities as a formation.

However, this thing is obviously not a secret. The little witch and Gu Yuan learned about this place from a book they bought casually in the bookstore.

It is said that there were evil demons in this place in the past, so the major forces in the Central Region led various forces to suppress the evil demons, and then used these five cities to suppress the evil demons underground.

But this is just a legend, and they don't know what the real situation is.

Gu Yuan and the little witch were not very interested in this. What they were interested in was how to find the person they wanted to find, and then reach the center of the Central Region to see what the situation was like there. This was their idea.

After a few days of travel, they arrived at Datu City and then settled down in Datu City. The purpose of their coming to Datu City was very obvious, which was to find Han Ji and see if there were any forces around that could help them find Han Ji's whereabouts for free. If it really doesn't work, then they need to keep moving forward. After all, they can't always stay in one place. Their time is also very precious and they can't just waste it like this. If it really doesn't work, they can only find another way again.

"Well, this city is actually no different from Dashui City. It's just a little bigger and has more people."

The little witch was a little disappointed, as she had thought it would be special.
