After nightfall, Qin Cheng flew ten miles away from the cultivators.

To be on guard, the range should naturally not be too close. With the strength of the Tribulation Realm monster, if you let go of the speed, you can quickly pass through several miles of land, and it will not be able to serve as a guard.

After looking around, Qin Cheng shook his head slightly.

The best place to guard is from a high place, overlooking all directions.

But this place is too flat.

Although there are occasional sand dunes in the desert, they are not high enough overall, so you cannot see too far.

Unless it's flying.

However, using a flying boat will definitely emit spiritual energy fluctuations, while a monk's levitation will continue to consume spiritual energy.

After finding no suitable place, Qin Cheng thought for a while and pointed.

A wisp of mysterious aura flowed out, and in the void in front of Qin Cheng, the spiritual energy of heaven and earth gathered under induction, gradually condensing into a huge rock.

Boom!

The rock fell to the ground, kicking up a burst of gravel and forming a huge rock ten meters square.

This is the rock gathering technique!

In Xingzun's memory, this technique can condense rocks as a means of bombardment. Rocks all over the sky are like meteorites falling from the sky. The scene is indeed spectacular.

However, the Rock Gathering Technique is different from the Heavenly Thunder Technique. The power of thunder can only be used for attack. However, according to Qin Cheng's observation, the stones condensed by the Rock Gathering Technique can exist for a long time, and like normal stones, they can be used in many places.

Come in handy.

The Rock Gathering Technique is only the last of the Thirty-Six Mysterious Techniques. It doesn't move much, and Qin Cheng doesn't intend to use it for attacks. The spiritual energy consumption is not high, and it can be used casually.

Boom!

As the mysterious method continued to operate, rocks condensed in front of Qin Cheng, and then stacked up. Each piece was about ten meters long, and gradually became smaller.

When these rocks are accumulated layer by layer, they form a towering stone tower that looks rough but is strong and sturdy.

Qin Cheng himself didn't expect that when he used the rock gathering technique for the first time, he actually made a high platform.

Upon hearing the sound, many monks also flew up.

Everyone was a little surprised when they saw the huge rock tower suddenly appearing in the desert from a few miles away.

Unexpectedly, Qin Cheng built a stone tower in this desert in an instant.

Moreover, these stones have no spiritual energy fluctuations at all, indicating that they were forcibly condensed by Qin Cheng with the power of their origin.

"This is the power of earth-origin rules."

The ancestor of the Chen family and others were moved, and then they were deep in thought.

Qin Cheng's method is quite clever. When he takes charge of the night watch, will he also make some arrangements to increase the intensity of the alert and at the same time avoid being disturbed by the monsters below the desert?

Satisfied with the effect of the stone tower, Qin Cheng jumped up and flew directly onto the high platform of dozens of feet.

Feeling good, Qin Cheng also arranged two stone towers in the other two directions for the two elders and the iron-eating beast to observe.

Although this stone tower is a little out of place in the yellow sand desert, after the rock gathering technique is condensed, these stones have no spiritual energy at all, just like a stone mountain. Even if there are monsters passing by, they will not be alerted.

Liu Fengqi couldn't help but laugh when he saw Qin Cheng, Li Li and others sitting cross-legged comfortably.

This thing Qin Cheng can condense, but he doesn't have this ability.

The condensed spiritual rock was reversed, but it was a completely different thing at that time. It was impossible to maintain the spiritual energy and control the shape of the spiritual rock all the time.

Seeing that the four people around him were a little jealous, Liu Fengqi looked even more depressed.

"What are you looking at? You have to cheer me up for a while and fly to me in mid-air to be on guard. I will change shifts every two hours. No one will be spared if I dare to neglect you." Liu Fengqi glared.

Without this stone tower, Liu Fengqi and others could only fly dozens of feet in the air, facing the biting wind and sand, while spending their spiritual energy to observe hard.

Compared with Li Li, Wang Ru and others sitting cross-legged with nourishment, this is far behind.

This made them feel that if they had followed Qin Cheng shamelessly, the vigil would have been more comfortable.

As for Qin Cheng, because of the distraction, he went directly into the medicine refining space.

At this time, I finally had time to take out the scroll I had obtained before and take a look.

Qin Cheng had obtained a total of two residual picture scrolls before.

One is to get it yourself, and the word "Qingfeng" is hidden in the residual picture.

The other one is from Xiong Qingyu, written with the word "sea of ​​clouds".

This residual image of Qin Cheng was originally given to Xiong Qingyu, but later the two of them left the city smoothly. According to the agreement, there was one statue for each person, so Xiong Qingyu returned the residual image.

And what will be in the scroll given by the Star Lord?

After taking apart the scroll, a picture of mountains appeared in front of Qin Cheng.

Sure enough, it was the painting scroll.

However, like the previously obtained residual image, this image is also missing, with only about half of its content.

After careful inspection, Qin Cheng caught the word "Guanshan" in a building that looked like a pavilion deep in the vast mountains.

"Breeze, sea of ​​clouds, view of mountains?"

I have to say that the names of the residual pictures left by Xing Zun are quite artistic.

Shaking his head in disappointment, Qin Cheng put away the remaining pictures.

You don't need to look closely to know that it is not something that can be fused with the previous two.

But, how many remaining pictures are there in total?

And what exactly are these things used for?

Before the fusion, Qin Cheng couldn't figure it out for the time being.

After observing the remaining pictures, Qin Cheng gathered his thoughts and began to practice with his eyes closed.

With the magic weapon of the medicine refining space, there is no need to worry about energy loss.

Let alone one night, even if he stayed awake for ten days and ten nights, there would be no problem for him.

The night passed quickly.

During this period, a few monster beasts without eyes wandered into this area. They didn't know whether they were lost or lost.

Qin Cheng took a few minor actions and solved these hidden dangers.

In the early morning of the next day, after practicing all night, the practitioners were in full condition and continued to set off.

During this period, Yang Gong and Taoist Huangmu made a special observation of Qincheng.

Qin Cheng was in high spirits, and it didn't look like he had been guarding the surrounding area all night.

As for Li Li and Wang Ru, they were in good condition after resting for half the night. Xiong Daxiong Er was directly pulled into the orb space by Qin Cheng to catch up on his sleep.

As for Liu Fengqi and others, it's a bit sad.

Everyone's energy was slack and their breath was exhausted.

Liu Fengqi yawned profusely, and the two weaker monks even had two dark circles on their eyes. Judging from their color, they were about to catch up with the iron-eating beasts.

"What a ghost. Did this kid get a chicken blood injection?"

After observing several people in Qincheng, Liu Fengqi and others secretly murmured.

Although they spent half the night apart, neither one was trustworthy to the other, so they didn't dare to practice with peace of mind, which was like staying up all night.

As for the other monks, they are also guessing whether it is actually not as tiring to be on guard as they thought.

Otherwise, why would Qin Cheng and the two elders look so good?

The journey is boring, no matter how beautiful the scenery is, you will get tired of it, and in the yellow sand desert, the scenery is almost unchanged.
