Standing in this huge square, Song Wei felt her insignificance.

There are three squares as big as football fields, surrounded by smooth arc stone walls. There are countless holes like honeycombs distributed on the stone walls. Each hole corresponds to a corridor, and above them is a chaotic zenith, with the light on it like stars.

In such an environment, anyone will feel like a dream.

Soon Song Wei discovered that the ground of this huge square was as smooth as a mirror, and there was no gap in the entire ground, as if it was a whole. The ground was made of something, but it actually had a warm jade texture.

If it was such a big piece of jade, it would be too terrifying.

Song Wei couldn't imagine where on earth could produce such a large piece of jade?

Compared with Song Wei, Xia Rufei's focus is different.

He has always been highly vigilant because the faint sense of crisis in his heart has not dissipated.

As soon as we arrived at the square, Xia Rufei first noticed a stone platform in the center of the square.

It was visually estimated that the circular stone platform was located in the center of the square, with stone steps in four directions, southeast, west and northeast. There were eight stone pillars standing on the stone platform, which looked like a boxing ring from afar.

"Song Wei, let's go over and take a look!" Xia Ruofei said.

After saying that, Xia Rufei took Song Wei's hand very naturally and walked towards the stone platform.

Song Wei seemed to be used to such intimate contact, and did not feel unnatural, but instead became closer to Xia Rufei.

The two walked towards the stone platform step by step. Xia Rufei always released his mental power and used his true energy to form an invisible protective cover outside the two of them, and he did not dare to relax for a moment.

He could sense that the aura in this square was very disordered, and he was not sure if there would be any mechanism along the way when he walked from here to Shitai. He could only maintain the highest alert and respond to changes in the same way.

However, the accident that Xia Rufei was worried about did not happen. The two of them walked safely in the empty square and soon arrived at the bottom of the stone platform.

Only after getting closer can I see clearly that the diameter of this stone platform is about ten meters, the material is the same as the ground of the square. It looks extremely warm under the zenith halo.

Xia Rufei could sense the scorching heat of the jade leaves, but he did not find the invisible toxin that had ever caused Song Wei to be infected.

So he said, "Song Wei, take off the gas mask!"

Song Wei trusted Xia Ruofei very much. Although she was still scared of that terrible toxin, she quickly took off her gas mask.

Xia Rufei naturally took off the gas mask and stuffed it into his bag together. He was indeed a little stuffy when he was wearing the gas mask.

"Let's go up and take a look!" Xia Ruofei said.

Song Wei nodded and took Xia Rufei's arm nervously. The two of them stepped on the steps side by side.

Xia Rufei was careful when he landed, but no changes occurred, and the two stood firmly on the steps.

They looked at each other and continued to climb up the stairs.

Soon they arrived on the stone platform. When they walked closer, Xia Rufei saw that the eight stone pillars surrounding the stone platform were carved with lifelike reliefs. The four corners of Xia Rufei could tell that they were the Azure Dragon, the White Tiger, the Vermillion Bird, and the Black Tortoise. As for the other four directions, they also portrayed strange beasts, but Xia Rufei did not study much about this and could not tell what it was.

In the middle of the stone platform, there is something similar to an altar, with nine golden dragons cast on it. These nine golden dragons hold a stone plate like stars holding the moon, and a black stone is placed on the stone plate.

A trace of glimmer appeared in Xia Rufei's eyes.

Boundary stone!

After a lot of trouble, I finally saw the boundary stone. No wonder I sensed that the jade leaves had reached a scorching point. It turned out that the boundary stone was here.

Song Wei seemed to sense Xia Rufei's emotions. She turned to look at Xia Rufei and asked, "Is that what you are looking for?"

Xia Ruofei nodded and said, "Yes! This trip is for it!"

After saying that, Xia Rufei stepped forward to take down the boundary stone.

But after just one step, Xia Rufei stopped and realized something seemed to be wrong.

He analyzed the existence of boundary stones in this ancient tomb through the breath of toxins in Song Wei's body.

But their judgment at that time was that this world stone should have been infected by something cold and cold. However, the world stone in front of them did not have any yin and cold breath, and Xia Rufei's mental power did not detect any of the existence of toxins.

Xia Rufei's mind was spinning quickly, and he thought of many possibilities, such as the existence of other realm stones in this underground palace.

But in the end he decided to take away the boundary stone first. No matter what, there is a boundary stone in front of him. Could it be that he will not be charged yet? As for whether there are other boundary stones, or where the cold things are, we can further explore later.

Xia Ruofei thought of this and said to Song Wei: "Song Wei, stand here and wait for me, I'll go over and take down the stone."

Song Wei subconsciously said: "I'll be with you..."

"There may be danger there!" Xia Ruofei said, "I'm afraid I won't be able to distract myself from protecting you... Just a few steps away, you can stand here and wait for me for two minutes..."

Song Wei thought for a while and said, "Okay then! Be careful..."

After all, she didn't want Xia Rufei to be distracted, and she also understood that this trip was basically a burden to Xia Rufei.

Xia Rufei nodded, let go of Song Wei's tenderness, and walked towards the altar in the center of the stone platform.

He always maintained a high alert, and his mental power was induced to the extreme, almost covering the entire stone platform. Once there was any disturbance, he could react immediately.

From his location to the center of the stone platform, it is only about five meters, seven or eight steps away.

One step, two steps, three steps...

Xia Ruofei tightened the strings in his heart, and Song Wei only clenched her fists and looked at Xia Ruofei's back with a nervous look on her face.

Finally, Xia Rufei arrived at the front of the altar safely.

Now the boundary stone is in front of Xia Rufei, and as long as he reaches out his hand, he can easily get it.

Xia Rufei carefully used his mental power to repeatedly investigate the altar, but did not find any danger, nor did he see any trace of the formation.

He finally made up his mind, took a deep breath, and reached out to grab the boundary stone.

Everything seemed calm, but Xia Rufei suddenly gave birth to a warning sign. Just when his hand was a few centimeters away from the boundary stone, he stopped forcibly.

However, an invisible vortex seemed to appear on the boundary stone. As soon as Xia Rufei's mental power came into contact with the vortex, it immediately disappeared, as if it had been swallowed by a black hole.

Immediately afterwards, Xia Rufei felt as if a breeze was blowing by, and he felt that his body was completely scanned from the inside out. This feeling was very uncomfortable.

Before Xia Rufei could react, the entire stone platform suddenly trembled violently.

Xia Rufei's face changed drastically. He gave up the boundary stone without hesitation and turned around and ran towards Song Wei.

However, the vibration amplitude of the stone platform suddenly increased, and Xia Rufei fell to the ground by the earthquake.

Immediately afterwards, all eight stone pillars began to collapse, and shocking cracks appeared on the smooth and jade-like ground. The cracks were pitch black and exuded a terrifying aura.

Xia Rufei had only had time to look at Song Wei, who was also sitting on the ground from the corner of his eyes, and then the entire stone platform began to collapse inward, and he was sucked in by the ever-expanding crack.

Xia Ruofei was anxious at this moment, but Song Wei had no cultivation at all. She was very dangerous under such circumstances.

However, he could not do anything now, his body fell down uncontrollably, with only the whistling sound of wind in his ears.

The only thing Xia Rufei can do is release his true energy to protect his whole body.

As for mental power, he had already tried it. Just like the realm stone just now, as long as his mental power penetrated his body, it would be swallowed silently and could not detect the surrounding situation at all.

Xia Rufei kept falling in the darkness where he could not see his fingers. After a while, he finally landed on the ground.

The moment he came into contact with the ground, Xia Rufei reacted instinctively and removed part of the momentum towards a rolling move.

However, even though he reacted quickly and his body-protecting true energy also played a protective role, he still felt his internal organs tremble violently, as if all had been moved. He even felt sweet in his throat and almost spurted out a mouthful of blood.

Xia Rufei knew that he was injured and might be seriously injured.

But he didn't care about himself at all, and struggled to sit up and shouted, "Song Wei! Song Wei!"

His voice kept echoing in the darkness, but what was replying to him was silence.

Xia Rufei unwillingly released his mental power again. Just like before, his mental power cannot be used here at all. As long as it penetrates out of his body, it will be swallowed up without leaving any trace.

Xia Rufei gritted his teeth, stood up with both hands and struggled. Then he thought to himself, and took out a zipp lighter from the space of the Lingtu, and sniffed and started to fire.

Since mental power cannot be used here, I can only search with my naked eyes.

Xia Rufei judged that if Song Wei fell like him, he would probably be unconscious now. After all, Song Wei did not have the true energy to protect her body, nor had she received such training to lift off the force from falling from high altitude.

With the trembling yellow flames of Zipp, Xia Rufei groped forward in this dark space, trying to find Song Wei.

However, he found nothing. It seemed that there was no darkness here, and the whole space was as quiet as death.

What Xia Rufei never expected was that Song Wei was still standing safely on the stone platform at this moment, and she had not experienced the scene of the collapse of the mountains and the earth just now.

However, Song Wei was also panicked and helpless at this time, because she paused when she saw Xia Rufei reaching her hand towards the black stone, and then her whole body disappeared out of thin air without warning.

This was completely beyond her perception, and most importantly, now in this huge and silent underground square, she is alone...
