"Did this once not be the sea?" This is the thought that came to mind after seeing this spectacular water city.
Surrounding the water city, there is a trench surrounding the city, but this trench feels a bit like a moat on land.
Searching along the city wall, he soon found a city gate. Looking at the huge and heavy city gate, Cheng Yu became more and more convinced that this was originally a land seat.
But Cheng Yu didn't think about it carefully.
Because of the city wall restrictions, Cheng Yu thought that entering the city would not be that simple. But the strange thing is that this city is full of prohibitions, but there is no prohibition blocking this city gate. This is really strange.
But that's fine, otherwise he would have to find a way to get into the city.
The soaring treasure light in the city has been there for a long time, and he doesn't know how long it will last. Otherwise, the city is so big, even if he enters, he won't be able to find the treasure place!
Although Cheng Yu was not blocked by a ban at the city gate, there was still a water ban, so after Cheng Yu entered the city, no water could enter.
At this time, Cheng Yu looked up and saw sea water flowing above the city, but it did not enter the city at all.
Viewed from this angle, this place is not only magnificent, but also very beautiful.
But Cheng Yu has no interest in paying attention to this at this time!
Instead, keep staring at the treasure light and rush forward!
He doesn't know when those powerful people will appear here, but before that, he'd better take away all the treasures!
However, when Cheng Yu found the place of treasure light, he was stunned.
The precious light turned out to be directly inspired by the square of the water city, but at this time he could see clearly that the white light appeared not just in this place.
There are five rays of light coming from five different directions, and each of these rays of light shines on the five places where the crystals are placed on the square.
And these five crystals once again emitted white light in the middle direction, and finally these five white lights converged into the huge sky-high treasure light.
"Is this a formation?" Cheng Yu looked at all this strangeness and didn't understand what it meant.
But based on his understanding of the formation and after observing the situation at the scene, this seemed to be a strange formation.
But Cheng Yu didn't know what this formation was used for.
"I have to go there and take a look!" Looking at the white light coming from five different directions, Cheng Yu did not dare to enter the formation rashly, for fear that something terrible would happen!
So Cheng Yu flew towards one of the places where the white light was coming from. He wanted to check first what the white light was coming from.
Cheng Yu traced the source and found that the white light was emitted from a tall tower-shaped building.
Cheng Yu has been feeling strange since he entered this water city, because he didn't find a human being here, or even any other creature.
But there are so many ferocious beasts outside this water city, which is really a strange thing.
However, at this time, Cheng Yu was standing under the tower, watching the white light from above shooting out from the top floor. Without any politeness, he directly pushed open the door of the tower and walked inside.
Entering the tower, it was very empty. Except for the spiraling stairs, Cheng Yu didn't find any extra items.
Cheng Yu slowly walked up the stairs with endless doubts. Although it seemed that there was no one here, it did not mean that there was no danger here.
It is an eternal truth to be careful in sailing the boat for thousands of years.
When they reached the second floor, there was nothing here, so Cheng Yu continued to the third floor, then the fourth floor... the fifth floor, the sixth floor, and finally Cheng Yu entered the ninth floor.
If Cheng Yu's estimate was correct, the white light should have come from the ninth floor.
And this ninth floor is different from the eight floors below. There is a wooden door here.
Facing this wooden door, Cheng Yu raised his hand but did not dare to push the door open, fearing that he would be in danger if he pushed the door.
However, Cheng Yu is not such a timid person. He needs those immortal bone warriors to help him take the lead in everything. Cheng Yu only hesitated slightly, but then pushed the door open.
Creak!
With a gentle push, the door opened directly, but at this moment, a powerful heat wave rushed out from inside.
Cheng Yu's expression changed and he quickly dodged.
The heat wave that hit the wall of the building dissipated directly without a trace!
At this time, Cheng Yu looked inside the room and saw a huge fire crystal placed inside. However, what surprised Cheng Yu was that although the fire crystal continued to radiate heat, it was not like an ordinary fire crystal. The Fire Spirit Crystal was wrapped in flames like that.
However, there are many white pure spirit crystals surrounding this huge fire spirit crystal.
"Strange, why do I feel like this fire spirit crystal seems to be absorbing energy?" Cheng Yu did not get close to the huge fire spirit crystal, but walked around the surrounding spirit crystals, especially when the white light was emitted. I wanted to stay and observe somewhere, but found that the white light actually had energy moving around.
He had always thought that the white light was coming from here, but now it seemed that the white light was coming from the square.
"What does this mean? Why did the people who lived here build such a strange thing?" Cheng Yu looked at the light rising into the sky through the place where the white light came in, and then looked at the other side of the square. The four towers also had white light shining into them, and they were extremely confused.
"This Fire Spirit Crystal is indeed absorbing energy. It seems that these pure Spirit Crystals outside are assisting the Fire Spirit Crystal in absorbing energy!" Cheng Yu looked at the Spirit Crystals surrounding the Fire Spirit Crystal and said.
"Could this be a spirit gathering array?" Cheng Yu thought for a while and asked.
The spirit gathering formation is a very common formation in the world of cultivation.
However, although the spirit gathering arrays are very common, the spirit gathering arrays arranged in different places are different.
Therefore, there are many types of spirit gathering arrays in this world. Any formation that can gather the power of spiritual energy can be called a spirit gathering array.
Although Cheng Yu has seen many spirit gathering arrays, this is the first time he has seen such a spirit gathering array.
Different spirit gathering arrays have different effects on gathering spiritual energy. Cheng Yu has not personally tried this spirit gathering array and does not know how effective it is.
But what Cheng Yu is confused about is, since those people set up a spirit gathering array here to help the fire spirit crystal absorb energy, what was their purpose?
"It seems that I have to look at other towers to find out the answer!" Cheng Yu didn't seem to see anything except a lot of doubts here, so he could only look elsewhere!
