Even if this wall is dodged by itself, it will divide the interior space in two. It's okay to jump out, at least you can walk back to the fork in the road, but if you jump in, you have to face the unknown road inside, who knows if this road will be the same dead end as the right road just now?

It's a pity that Rollo didn't have time to congratulate himself on his cleverness, and he fell into distress. She looked at the ground under her feet and frowned.

She can't let go of her feet, and if she does, the wall above will fall down. Luckily, the traps here are old-fashioned, not the kind of traps that will drop when touched.

Rollo thought about his height and weight, calculated in his mind the pressure of stepping on the dirt with one foot, and after a while, he came up with a value.

Thankfully, Rollo wasn't more fortunate than ever, but she was pretty good at physics. It's also because the recent exercise has developed the potential of her body, and even her mind.

Having calculated an approximate value, Rollo began to think about finding something to replace his weight. She glanced around, and around her was a wall of dirt that was empty.

Rollo looked down at the land, deep in thought.

Suddenly, she saw the dirt on which her feet were stepping, and a thought flashed through her mind.

Although she wasn't sure if it would work, she still had to give it a try, and if it failed, she would go back. Luo Luo would rather not take this path and lose the opportunity to hunt for treasures, rather than face the unknown ahead, especially if she doesn't even know where the retreat is.

Little by little, Rollo bent down, trying to keep his balance. The strength of stepping on the feet does not increase or decrease.

Crouching down smoothly, she began to scrape the dirt from the ground.

Although the mud is solid to step on, there is actually a lot of scattered dirt and dust left on the road.

Rollo opened his mouth and blew hard, blowing up a cloud of dust.

Immediately after, she took out the vajra talisman that had no effect after using it before, rolled it up and gently scraped it on the ground. After scraping one place, she continued to blow vigorously in other places, and then continued to scrape.

After about half an hour, Rollo finally stopped. She didn't dare to rub her eyes with her hands, because her hands were already covered with dust and could only blink desperately there. In a few moments, tears flowed from her eyes.

After shedding tears. Her eyes were much more comfortable.

At this time, when he looked down again, a square bluestone brick appeared in front of Luo Luo.

And her right foot just stepped on the center of this stone brick. It just so happens that there is also a circle in the center of this stone brick.

If it weren't for the fact that there was a problem with the step this time. Rollo wouldn't have realized that what she was treading under her feet wasn't mud. It's stony.

The stone bricks she stepped on. It's just one of many bricks.

Seeing this stone brick, Rollo's heart became even more confused about the surrounding environment. What was it that made this place so covered in mud that it was impossible to see what it was?

Rollo shook his head. Putting this question in the depths of her heart, she has more important things to do at this time.

Rollo gathered all the dirt he had swept up and piled it up next to him little by little. Although the dirt looks very light, in fact, it is a lot of weight to collect them all.

And since he knew that what he was stepping on was nothing more than bluestone bricks covered in dirt, Rollo also hit the idea of bricks elsewhere. There's not enough dirt in this place, and that's okay, there's dirt in other places.

In a short time, a large pile of dirt was collected by Rollo.

Rollo's body bent, allowing his hand to hold down the circle in the middle. Then let your right foot lift little by little. For every point her foot lifted, her hand followed with a force.

With Rollo's current body position, it would be difficult for her to retreat in time if there was a slight mistake that caused the wall to fall from above. So Rollo couldn't help but sweat a few more drops on his forehead, and he was a little nervous in his heart.

When he finally lifted his whole foot from the circle, Rollo's hand pressed heavily against the circle with the force exerted by his foot on the stone brick.

Seeing that there was no change in his surroundings, Rollo exhaled slightly. She didn't look up at the sunken spot above her head, for she was afraid that changing her position would upset her balance.

Then came the more crucial moment, when Rollo had to fill the center of the circle with dirt.

The bluestone brick is large, and its central circle is also large. I walked so many steps before and didn't win the lottery, and the reason why I won the lottery this time is not only because this place may be special, but also because I stepped on the center of the inner circle of the stone bricks.

According to the method described in the book, Rollo swept the surrounding dirt into the center of the circle with one hand.

When the dirt had reached a certain level, and Rollo thought that it was almost enough, she decided to let go of her fingers pressed on the center of the circle.

Of course, when she lets go of her hand, Luo Luo will also adjust her posture first, so as not to accidentally fall down the wall and she will not be able to retreat because of her posture.

Everything was ready, Rollo exhaled softly, and then let go! The moment she let go, she immediately jumped out!

"Click!" The top of the concave moved down, and a small piece of dust fell from above, but finally came to a steady stop on it, and did not fall.

Luo Luo couldn't help but smile when she saw this scene, fortunately, this mechanism was relatively simple, so she was able to crack it according to the method in the book.

Rollo took out a tissue from the small cloth bag, wiped the sweat from his forehead, and decided to move on.

She didn't know that the ground was covered with a layer of dirt, so she didn't deliberately look at the ground with her discerning eyes. It's just that now that Rollo knows, then she won't make the same mistake in the same place again.

Rollo closed his eyes, and the next moment - his eyes opened!

This time, Luo Luo used the ability to go deeper, her insight had evolved once as early as the last time she was besieged by ghosts, and the evolved wisdom needed spiritual power in her body to use.

In order to save spiritual power, Luo Luo has been opening his ordinary eyes.

Fortunately, in the past few days, she has already had a certain amount of spiritual power in her body through the cultivation of Dream Return, and the spiritual power required by the evolved Insight is not very much, and the spiritual power in the body is not much, but it is enough to support the evolved Insight for a long time. (To be continued.) )
