Watching Song Nianzi leave, Duan Tianyu turned around and looked at the river. It is unknown where this river flows down, but it is certain that the spirit stones are in the river, and there are many of them! In this isolated place, what makes Duan Tianyu most curious is this river, which gives people a sense of mystery and makes people fall into it......

Duan Tianyu looked at the river with his divine sense again, but he still couldn't see the bottom of the river! He had already tried several times when he first came in, but he didn't succeed! It seemed that he had to go to the river to have a look.

Duan Tianyu took off his boots and walked barefoot into the river. The river was flowing soothingly, calm and gentle! If it weren't for the spirit stone, Duan Tianyu would really want to take a good bath here......

In the river, a few fish did not scatter because of Duan Tianyu's intrusion, they circled around Duan Tianyu a few times, and then swam leisurely!

Duan Tianyu continued to dive, but after diving for a long time, he couldn't see the bottom of the river, and more importantly, he couldn't see it with his divine sense, and it was like night below. After a few more minutes of diving, it was still the same. I had no choice but to swim forward.

There was nothing in the river except for the occasional sight of three or five fish. It wasn't until he vaguely saw a vague object that Duan Tianyu sped up his speed.

It turned out to be a boulder. It's just that the head is exposed here, and the lower part of the boulder blends with the darkness at the bottom of the river, so you can't see it at all. Duan Tianyu repeatedly circled around the boulder a few times, watching carefully, but he didn't find anything abnormal!

It had already been half an hour, and Duan Tianyu's current cultivation was not enough to stay in the river for a long time without going to ventilate! Diving up to the river, his divine sense found that his current position was more than 1,000 meters away from the place where he had just descended the river. And Ma Hongming and they have also begun to cultivate. After stopping on the river for less than 1 minute and finding that there was no special situation, Duan Tianyu dived down again......

Continuing to move forward, soon Duan Tianyu saw another boulder, almost the same as the one he had just seen! However, Duan Tianyu still carefully observed it before leaving here.

Intermittently, on the way to the journey, Duan Tianyu found several more boulders. Without exception, it's all the same as the previous one. I don't know how long I have been moving forward again, but there is nothing else except the boulder of the same shape, and there is no end in sight and the bottom of the river......

After observing a boulder again, Duan Tianyu stopped advancing. He surfaced and found himself in the middle of where he had first come up for air and where he had just come down from the river. That is, he entered a Stonehenge and kept circling around these boulders without advancing at all......

Duan Tianyu floated on the surface of the water and thought for a moment before diving into the water again. He came to the boulder below and looked at it again, then walked forward. Continue to see the boulders you pass by. Finally, he found something strange in front of a boulder!

At first glance, this boulder looks almost identical to any other boulder, with the only difference being the angle at which the boulder stands. Those boulders are all standing upright at 90°, and this boulder stands at an angle of about 85°, so you can't see it at all if you don't look closely. And it's in the middle of the river, which is even more imperceptible!

Using this boulder as a starting point, Duan Tianyu began to explore again. Continuing on, I passed one boulder after another, and finally returned to this boulder.

This should be a formation, a high-level formation made of 9 boulders. It traps the people who enter the formation, and no matter how you go inside, you can't get out, and the only way is to surface.

Where was the eye of this Stonehenge formation, with Duan Tianyu's current cultivation, it was indeed unknown! However, this did not prevent him from continuing to explore this formation in depth.

Just now, he noticed that there was a flash of light just below the boulder. Although it was only a flash, it was still captured by Duan Tianyu. He kept staring at the place where the light had just appeared, and sure enough, the light continued to flicker.

The corners of Duan Tianyu's lips raised slightly, and he came to the boulder, leaning against it, and slowly began to fall down......

Slowly entering the darkness, it was like falling into an ink tank. Duan Tianyu leaned out of his divine sense again, his body was close to the boulder, and his hands were also holding on to the boulder, sinking carefully little by little......

The further down you go, the deeper the intensity of the aura. At this time, the divine consciousness can also sweep to the vicinity of about 3 meters, but there is nothing but darkness......

Finally, Duan Tianyu stopped falling and stepped on the bottom of the river with both feet. Suddenly, a violent breath rose from the soles of his feet and spread throughout his body. At this moment, Duan Tianyu was like being in a sea of aura, extremely comfortable and happy, and he couldn't wait to sit on it immediately and start cultivating!

Duan Tianyu stepped on a spirit stone mountain. He walked a few meters forward, and the range of his divine sense was full of spirit stones! Without thinking about it, he took out a new storage ring from the storage ring and began to collect the spirit stones!

When he got the Void Stone, Duan Tianyu refined a total of 10 storage rings, used one for himself, gave one to Song Nianzi, and left 8 pieces. In a short time, Duan Tianyu had already filled the spirit stone of a storage ring.

A storage ring is about hundreds of cubic meters, and a spirit stone is the size of a glass ball, so the spirit stones contained in this ring are more than tens of thousands! But even if it is filled with two rings, the spirit stones here have not decreased......

Duan Tianyu took out the second ring and walked forward while collecting the spirit stone. He gradually felt that the aura in front of him was even richer than here! Could it be that there were high-grade spirit stones in front of him?

Duan Tianyu sped up his pace. Sure enough, a blue-gray pile of spirit stones appeared in Duan Tianyu's divine sense. The pile of spirit stones in front of it was obviously much less than the spirit stones under Duan Tianyu's feet, but the aura it emitted was much richer, and it deserved to be a medium-grade spirit stone!

Spirit stones are divided into four grades: lower, middle, upper, and superb. The spirit stone is the common currency in the cultivation world, and the exchange ratio is 1 top grade is equal to 1000 upper grade, 1 upper grade is equal to 1000 medium grade, and 1 medium grade is equal to 1000 lower grade. I didn't expect there to be so many medium-grade spirit stones here, this is really an unexpected gain!

Duan Tianyu jumped off the Spirit Stone Mountain and came to the Spirit Stone Pile. He didn't rush to collect the spirit stone, but stood here and swept around again with his divine sense. It wasn't all dark, especially in front of it, there seemed to be a building. However, the divine consciousness was blocked and could not be extended any further......

Duan Tianyu squatted down and thought while collecting the spirit stones: It seems that the scattered spirit stones outside have all been scattered from here. But I don't know why there are so many spirit stones here? Is it a naturally formed spirit stone mine, or who left it? What is going on with this profound formation? What is the suspected building in front of him? These are unknown!

This formation, Duan Tianyu can enter it, and there is a lot of luck. In this formation, he was almost blind. Fortunately, the current position is the bottom of the formation, and the power of the forbidden is much smaller, allowing him to grope out the general situation nearby!

He looked up again at something vague in front of him, like a door, like a window. It is half-open and half-closed, swinging from side to side, making it difficult to see what's inside, and attracting people to push it open and go inside to find out!

Duan Tianyu stood up, put away the ring that had already contained half of the spirit stone, and walked forward slowly. After taking a few steps, Duan Tianyu took out the Tianshu Sword and held it in his hand, the suspected building in front of him was mysterious and weird, and he had to be on guard!

It was really a window, and Duan Tianyu's hand holding the sword tightened a little tighter. The hand holding the sword was behind him, and the other hand reached forward to open the window. As soon as he was about to touch the window, he felt a strange force coming towards him, and he was bounced away before he could defend himself......

Duan Tianyu was ejected by a mysterious force for more than 10 meters before stopping! At this time, he was half-squatting on the ground, looking ahead in surprise!

What was going on? Where did that strange power come from? He didn't know what to do, he got up, and walked to the window again. When he was about to touch the window, he was still bounced back......

Because of his preparation, this time Duan Tianyu just turned around in mid-air and stood upright on the ground. He just stared ahead, motionless, not knowing what he was thinking......

A few minutes later, Duan Tianyu moved. He does not move forward, but laterally. It was just a window, and now he wanted to see where the door to this building was?

Sure enough, after a while, he turned to the front and saw the gate of the building. Duan Tianyu looked up at the stone gate, he didn't expect this building to be so grand and tall!

This door is more than 10 meters high, and standing at its feet, you feel so small, like a giant, standing in front of you, giving people a heavy sense of oppression!

Two monsters are carved on the two door leaves. On the left is a sphin-faced, six-hoofed monogonal monster, and on the right is a monster with a snake's head and a chicken's tail, one leg and two wings. These two lifelike monsters gaze at those who come here with a condescending and menacing gaze, making it intimidating for anyone trying to enter the building!

Duan Tianyu didn't know what the monsters on the door were called! No, looking at their appearance, they should be very powerful! Take out the crystal ball and record these two monsters and this strange building into it, waiting to be investigated!

The role of the crystal ball in the spiritual world is equivalent to that of today's camera and video equipment. Images and events can be recorded......
