Outside the wall, Xiao Qianhan stood still, with neither the next move nor the plan to leave.

This wall, or this stone room, from the outside, it looks like two situations are possible, the area is not big or small!

It is enough to take out a room inside, and if there are too many bricks left, such a stone lump can be built!

After a while, she began to mobilize the source power and hit the wall with a hard elbow!

"Hey!" Xiao Qianhan took a painful breath.

This wall is too hard, too strong! This time I didn't do anything to the wall, my arm hurts enough!

Of course, she is not stupid enough to use her body to break through the stone wall. What she has to do is to detect whether the stone wall is empty or solid!

To say that this detection method is also quite advanced, it is called sonar detection!

In layman's terms, it is to use the echo obtained by hitting the wall to judge the situation inside. Because the walls are too thick, source power is required.

But it was too painful to hit, and if you hit it all over the place, you'd have to fall apart.

"Bang!" A sledgehammer was released from the spiritualizer, and it hit the wall hard. If it wasn't for fear of fainting Feng Lie's spirit, she wouldn't mind using the Feng Lie sword.

As for the anti-shock power, just let the sledgehammer dissipate and then condense it, and you won't be affected by a tiny bit.

Next, the sound of the crash was incessant, but it never leaked out under the restraint of her soundproofing.

It has been more than an hour after she knocked it all over with a sledgehammer.

The effect is also very obvious. There is indeed a space in this stone wall, but this space is pitifully small and can only accommodate an adult sitting, not even lying down.

As for whether there was anyone in that space, she couldn't be sure.

But a space of this size, in such a place, surrounded by a pile of such sturdy stones, gives the impression that someone has been sealed away!

It is also because of this idea that she did not continue to do it.

After confirming that there is space inside, as long as she wants to, it is not impossible to break these stones, it just takes some effort.

But if the person sealed inside was released because of her...

Now the situation in Beiwuzhou is too chaotic, if the people inside are stubborn with the enemy and deal with the invaders together, it will be fine.

Of course, it is not known whether there is anyone inside, so she intends to use her power to try to see if there is anyone in the pile of rocks!

Passing the source power through the stone wall and entering it, although the loss is very large, is not an option.

He pressed his hand on the gap in the stone wall, mobilized the source force to slowly transport it in, and ingested a Sixiang Pill!

With her current total source power, I am afraid that it is not enough to support the loss! Because the stone wall is too thick!

The source power is like a snail crawling in the stone wall, and every time it moves, it will suffer a lot of loss!

According to estimates, the four elephant pills should be enough to support the vacancy of insufficient source energy in her body, but just when the source energy in her body was about to be exhausted, the source energy that penetrated the stone wall still did not reach that space!

The speed is slow and the losses on the road are beyond estimates!

Just when she was about to take a few more pills, suddenly the source force in the wall seemed to have encountered some obstacle, and it was all bounced back in an instant, with no resistance!

All the source energy returned to Xiao Qianhan's body, but even so, she was still hit by the force of the rebound, and the whole person fell into the soil behind her for a distance of more than ten meters!

That power is too strong! Strong enough to even look up!

The formidable power of that power should be equivalent to the attack of the Void Rotation Realm, stronger than Ji Hongyan's full-strength strike!

And this power gave her the feeling that it was a random blow, the kind that didn't care at all! If you use it with all your strength, the power is unimaginable!

Is there such a strong person in Beiwuzhou? And it was hidden under the imperial mausoleum, but she had never heard of Yun Jingchen, Yun Mojin and others mentioned it, not a word!

Who is this person? Why are you hiding here?

After she protected herself with all her strength, she came out of the soil and stood in front of the wall again.

After a while, the stone wall was as deadly as ever, without any movement, as if the blow just now didn't exist.

Xiao Qianhan frowned, and after waiting for a while to see that there was still no movement, he took another Four Elephant Pill to infiltrate the source power into the stone wall!

Just like last time, when her source power was about to be exhausted, that power reappeared, and she was buried again by the soil when she was prepared, but it was not as deep as the last time.

He cautiously returned to the stone wall, and after waiting for a while, a dead silence returned.

After going back and forth for many times, Xiao Qianhan couldn't wait any longer. When he came back, he started to deliver the source power again. The result was the same. The shallowest time, she was buried five meters!

From the beginning to the end, there was no sound coming from it, and there was no second attack except to bounce the source power back!

This made her even more interested!

Obviously it was something like a formation ban, and it was defensive, not a real person!

However, to be able to arrange such a powerful thing, I am afraid that my strength is boundless!

This also shows one thing, that is, what is hidden in that small space is very important!

Standing there and thinking for a while, she placed a teleportation array under her feet and planned to leave.

She was indeed able to break through the stone wall, but it took too long!

She also planned to take a look at what was hidden inside, but the news from the Su family's secret realm made her give up this plan.

"Qianhan, that person wants to talk to you alone, we won't say anything if we ask." Long Yu communicated with Xiao Qianhan inside.

"Don't say anything?" Xiao Qianhan was not surprised. If the other party is a soft head, he will not be able to withstand the torture of the fifth prince early in the morning.

"We were tortured and questioned. He didn't say anything except his name. He kept saying that he would only say it when he saw you!" Long Yu was very helpless. It was the first time he had met such a tough guy, and he was still a targeted guy!

If it wasn't for the fact that this person's cultivation was not Xiao Qianhan's opponent, he would not tell Xiao Qianhan about it.

"What's his name?" Xiao Qianhan asked.

"He said his name was Ah Han." Long Yu replied.

It was this name that made Xiao Qianhan decide to leave immediately!

Ah Han, it's time to find her again! Could it be Qi Wenhan?

She didn't enter the Su Family Secret Realm to take a look first, but directly set up the teleportation array!

But just as she started to set up the teleportation formation, suddenly there was movement inside the stone wall!

This time it was no longer elastic, but a voice, a somewhat familiar voice.

"Break the stone wall and I can tell you anything you want to know!"

Xiao Qianhan's movements suddenly stopped, he raised his head and looked at the stone wall in disbelief, trying to penetrate into the stone wall!

That voice turned out to be very similar to the mysterious woman in the secret room of the agency!
