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

The square, the size of three football fields, was surrounded by smooth, arcing stone walls with countless beehive-like holes, each corresponding to a corridor, and above them was a chaotic zenith with a bright light like stars.

In such an environment, anyone will have a feeling of being in a dream.

Soon Song Wei found that the ground of this huge square was as smooth as a mirror, and there were no gaps in the entire ground, as if it was a whole, and the ground did not know what material it was made of, but there was a warm jade texture.

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

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

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

He has always maintained a high degree of vigilance, because the faint sense of crisis in his heart has not dissipated.

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

The circular stone platform is located in the center of the square, with stone steps in the southeast, northwest, and northwest directions, and eight stone pillars standing on the stone platform, which looks like a boxing ring from a distance.

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

After speaking, Xia Ruofei naturally took Song Wei's hand and walked towards the stone platform.

Song Wei seemed to be used to this kind of intimate contact, and she didn't feel unnatural, but leaned on Xia Ruofei to get closer.

The two walked towards the stone platform step by step, Xia Ruofei always released his spiritual power, and used his true qi to form an invisible protective shield outside the two of them, and he didn't dare to relax for a moment.

He could sense that the aura in this square was very disordered, and he wasn't sure if there would be any mechanism along the way from here to the stone platform, so he could only maintain the highest vigilance to respond to all changes.

However, the accident that Xia Ruofei was worried about did not happen, and the two of them went all the way safely in the empty square, and soon came to the bottom of the stone platform.

When I got closer, I could see clearly that the diameter of this stone platform was about ten meters, and the material was the same as the ground of the square.

Xia Ruofei could feel the burning of the sensing jade leaf, but he didn't find the invisible toxin that had caused Song Wei to be hit.

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

Song Wei trusted Xia Ruofei very much, and although she was apprehensive about the terrible toxin, she quickly took off her gas mask.

Xia Ruofei naturally took off the gas mask and stuffed it into his bag together, he was indeed a little depressed when he had been wearing a gas mask.

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

Song Wei nodded, grabbed Xia Ruofei's arm a little nervously, and the two stepped on the steps side by side.

Xia Ruofei was cautious when he landed, but there was no abnormality, and the two stood firmly on the steps.

They glanced at each other and continued their way up the stairs.

Soon they came to the stone platform, and when they got closer, Xia Ruofei saw that the eight stone pillars around the stone platform were depicted with lifelike reliefs, and the directions of the four corners Xia Ruofei could see that they were Qinglong, White Tiger, Vermilion Bird, and Xuanwu, and the other four directions were also depicted by foreign beasts, but Xia Ruofei didn't study much about this and couldn't tell what it was.

In the middle of the stone platform, there is an altar-like thing, on which are cast nine golden dragons, which hold a stone plate like the stars holding the moon, and on the stone plate is placed a black stone.

Xia Ruofei's eyes showed a hint of brilliance.

Boundary Stones!

This trip took a lot of trouble, and now that I finally saw the boundary stone, it is no wonder that the induction jade leaf has reached the point of scorching, and it turns out that the boundary stone is here.

Song Wei also seemed to sense Xia Ruofei's emotions, she turned her head to look at Xia Ruofei and asked, "Is that what you're looking for?"

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

After speaking, Xia Ruofei stepped forward to take down the boundary stone.

However, after only taking a step, Xia Ruofei stopped, and he realized that something seemed to be wrong.

Through the breath of the toxin in Song Wei's body, he and Xia Qing analyzed the existence of boundary stones in this ancient tomb.

However, their judgment at that time was that this boundary stone should have been infected by a cold thing, but the boundary stone in front of them did not have the slightest cold aura, and Xia Ruofei's spiritual power did not detect the existence of any trace of toxin.

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

However, in the end, he still decided to take the boundary stone first, anyway, there is already a boundary stone in front of him, can't he still collect it? As for whether there are other boundary stones, or where the cold thing is, it can be further explored later.

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

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

"There may be danger over there!" Xia Ruofei said, "I'm afraid I won't be able to be distracted to protect you then...... Just a few steps away, you can just stand here and wait for me for two minutes......"

Song Wei thought for a while and said, "Okay then, you pay attention to safety......

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

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

He always maintained a high level of vigilance, and his mental power was urged to the extreme, almost enveloping the entire stone platform, and if there was any disturbance, he could react immediately.

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

One-step, two-step, three-step......

Xia Ruofei tightened the strings in her heart, and Song Wei only clenched her fists and looked at Xia Ruofei's back nervously.

Finally, Xia Ruofei came to the front of the altar safe and sound.

Now that boundary stone was in front of Xia Ruofei, as long as he stretched out his hand, he could easily get it.

Xia Ruofei carefully used his spiritual power to repeatedly inspect this altar, but he did not find any danger, nor did he see a trace of the formation.

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

Everything seemed to be calm, but Xia Ruofei suddenly had a hint of alarm, and when his hand was still a few centimeters away from the boundary stone, he stopped abruptly.

However, an invisible vortex seemed to appear on the boundary stone, and as soon as Xia Ruofei's spiritual power came into contact with this vortex, it immediately dissipated, as if it had been swallowed by a black hole.

Immediately afterwards, Xia Ruofei felt as if there was a breeze blowing, and he felt as if his body had been thoroughly scanned by something from the inside out, which was very uncomfortable.

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

Xia Ruofei's face changed drastically, he gave up this boundary stone without hesitation, and directly turned around and ran in the direction of Song Wei.

However, the amplitude of the shaking of the stone platform suddenly increased, and Xia Ruofei was so shocked that he fell to the ground.

Immediately after, the eight stone pillars began to collapse, and shocking cracks appeared in the smooth jade-like ground, which was dark and filled with a terrifying aura.

Xia Ruofei only had time to glance at Song Wei, who was also sitting on the ground, out of the corner of his eye, and then the entire stone platform began to collapse inward, and he was suddenly sucked in by the continuously expanding cracks.

Xia Ruofei was anxious at the moment, Song Wei didn't have the slightest cultivation, she was very dangerous in such a situation.

However, he couldn't do anything now, his body fell uncontrollably, and all he could hear was the whirring sound of the wind.

The only thing Xia Ruofei could do was to release his true qi to protect his whole body.

As for the spiritual power, he had already tried it, just like the boundary stone just now, as long as his spiritual power came out of his body, it would immediately be swallowed silently, and he would not be able to investigate the surrounding situation at all.

Xia Ruofei kept falling in the darkness where he couldn't see his fingers, and he didn't know how long it took, and finally fell to the ground.

The moment he made contact with the ground, Xia Ruofei reacted instinctively, and unloaded part of the momentum with a tumbling action forward.

However, Rao is quick response, coupled with the protective true qi also played a protective role, he still felt a violent shock in his internal organs, as if all of them were displaced, and he even had a sweet throat, and a mouthful of blood almost spurted out.

Xia Ruofei knew that he was injured, and he might not be lightly injured.

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

His voice echoed in the darkness, but all that was answered was silence.

Xia Ruofei unleashed his spiritual power again, just like just now, spiritual power could not be used here at all, as long as it was out of the body, it would be devoured without a trace.

Xia Ruofei gritted his teeth, stood up with both hands on the ground, and then with a thought, he took out a Zippo lighter from the Lingtu space and ignited it with a snort.

Since spiritual power can't be used here, it can only be found with the naked eye.

Xia Ruofei judged that if Song Wei fell like him, it was very likely that she would be in a coma now, after all, Song Wei did not have the true qi to protect her body, and she had not received this kind of unloading training for falling from a high altitude.

With the fluttering yellow light of the Zippo, Xia Ruofei groped his way through this dark space, trying to find Song Wei.

However, he found nothing, and the whole space seemed to be silent except for darkness and darkness.

What Xia Ruofei never expected was that at this moment, Song Wei was still standing on the stone platform unharmed, and she had not experienced the scene of the landslide just now.

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

This was completely beyond her realization, and most importantly, she was now alone in this huge and dead underground square......
