After the banquet, Cheng Yu returned to the room again. Now that he is a guest of the City Lord's Mansion, it is a matter of course that he lives here.

It's just that he wants to know why this Aoki City won't be breached by Rucheng, but he also knows very well that if he goes to Qinghai again, not only will Qinghai be suspicious of him, but he will definitely not tell him the real reason.

Therefore, if Cheng Yu really wants to know the reason, I am afraid that he can only rely on himself to investigate.

But now that he is a guest anyway, in this city lord's mansion, except for a few places, there is really no place he can't go.

But what disappointed him was that although the City Lord's Mansion was large, it was not easy to find the answer he wanted.

Cheng Yu wanted to go outside the city to see the battle situation, but he couldn't hear the shouts and killings outside at this time, so he found a subordinate in the city lord's mansion to inquire, only to know that Rucheng had withdrawn.

In the next few days, Cheng Yu always made various inquiries, hoping to find the reason why Aoki City would not be breached. At the same time, he also found out that there are still many masters who go out of the city every night.

For a few days, the city would be attacked every six hours, and although each attack would not last long, it would make Aoki Castle miserable.

Especially the people of the City Lord's Mansion kept losing money in these siege battles. Fortunately, Elder Qin also knew about the situation in Qinghai, so he still sent Long Ying's people to help them defend the city.

Cheng Yu also watched the siege of Rucheng several times when he returned to the East Gate Tower, and he did find something very wrong.

The strength of the people sent by Yucheng to attack the city was not weak, and every time they attacked the city, they were not only superior in numbers, but also superior in strength.

From Cheng Yu's point of view, if Rucheng really wants to attack Aoki City, then with the strength of Rucheng, it should be completely possible to attack Aoki City.

However, this is also in response to Qinghai's words, Aoki City will not break.

"Could it be that the siege of Rucheng is fake?" Cheng Yu suddenly had an incredible thought in his heart, but when he saw that Rucheng was besieging the city, the soldiers on both sides had also died a lot, but he was a little suspicious.

"No, there must be something strange about it. Even if Rucheng didn't really want to attack the city, it was impossible for Qinghai to know that it was. However, judging from the current situation, Qinghai seems to know that Rucheng is not really going to attack the city.

Could it be that both of them already knew all this? What is going on?" Cheng Yu became more and more puzzled the more he thought about it.

Yucheng is the jurisdiction of the Xiaowai Dynasty, and Aoki Castle is the jurisdiction of the Dragonhawk Wai Dynasty, so it stands to reason that these two cities should also be enemies.

But now they seem to have agreed to pretend to go to war, what is the purpose of this?

"Could it be ......" Cheng Yu suddenly had a flash of inspiration, as if he had thought of something.

"If this is really just a discussion between the Dragon Eagle Outer Dynasty and the Xiao Foreign Dynasty for a long time, then all this becomes reasonable. But why did they pretend to go to war?" Cheng Yu thought of a possibility, that is, there seemed to be some kind of agreement between the Longying Foreign Dynasty and the Xiaowai Foreign Dynasty.

"Pretend to go to war..... Secretly but colluded together...... This is...... Alliance?" Cheng Yu kept muttering in his heart, constantly analyzing what secrets were hidden under these unusual appearances.

In the end, he thought of a result, that is, the Dragon Eagle Outer Dynasty and the Xiao Overseas Dynasty had already secretly formed an alliance.

"If that's the case, it's going to be a problem. He originally wanted to let the two foreign dynasties fight between them, but now that they are secretly allied, so the possibility of him wanting them to fight is not high. Cheng Yu thought with some disappointment.

"No, now there are masters in this Aoki City who quietly leave the city every day, if they really form an alliance, then there must be other purposes? Could it be that they want to find out Bai Li?" Cheng Yu suddenly remembered the masters who went out from Aoki City every night.

After all, in his opinion, the main reason why Rucheng and Aoki City will fight is the Blue Heart City Incident and the Luoshui City Incident that he asked Bai Li to create.

So they are forming an alliance now, perhaps to find out if they are separated from them.

Thinking of this, Cheng Yu hurriedly used a special method to sense Bai Li's location, but fortunately, Bai Li was hiding quite hidden, and it should be impossible for them to find Bai Li.

Moreover, as far as the masters he saw, even if he really found Bai Li, it would be impossible to stop Bai Li. Because those masters who went out of the city were only monks who were above the distraction period.

Although such a monk is a master to many people, to Cheng Yu and Bai Li, he is really nothing. How many such people come in vain, they can kill as many as they want.

So thinking of this, Cheng Yu also felt a lot more at ease.

"Huh? It doesn't seem right! If they want to find Bai Li and them secretly, then there is no need for them to pretend to go to war? Could it be that there are other secrets between the Longying Foreign Dynasty and the Xiaowai Dynasty?" Cheng Yu thought about it, and suddenly thought of something unreasonable, and suddenly felt puzzled again.

"No, it seems that I can't stay in Aoki City for the time being, I have to follow those people who go out of the city to see where they are going!" Cheng Yu thought about it for a long time, and felt that it seemed that he couldn't investigate anything if he stayed in Aoki City any longer.

If they had formed an alliance with the Xiaohai Dynasty a long time ago, then they would indeed not be able to fight this battle. Then it doesn't make much sense for him to stay in this Aoki Castle.

So, Cheng Yu casually found a reason, said to Qinghai and left Aoki City.

Although Qinghai didn't want Cheng Yu to leave, he had also said before that he would not interfere with Cheng Yu's freedom. And Cheng Yu also said that he just had something to do, and he would come back when the time came, so he felt a little better.

In order not to attract the attention of others, Cheng Yu walked out of the city from the north gate in broad daylight. Because those people were out of the northern castle of Aoki Castle, he could only hide outside the north gate.

waited until late at night when Cheng Yu saw some people quietly coming out of the north gate, Cheng Yu smiled faintly, and sure enough, he didn't let him wait in vain.

So, Cheng Yu quietly followed these people. Originally, Cheng Yu had been following these people, but after following for a few days, Cheng Yu became a little impatient.

This cultivation realm is so big, if it takes several months for these people to go to the place they want to go, then wouldn't it be a waste of time.

Anyway, there is Yao Na's curved mirror, and wherever there are flowers and trees, no one can escape from the palm of his hand. So, when they left a city again and came to a barren mountain and wilderness, Cheng Yu directly chose to take action.

Rather than keep following them like this, it's better to just arrest these people and ask them for clarification.
