D-level nightmares, homophonic words can also be called top-level nightmares, if the A-level nightmare is the ultimate embodiment of the nightmare in the limited rules, then the D-level nightmare is the highest embodiment of the degree of freedom, basically it can be said that there is no upper limit of strength restrictions, the nightmare time is also extremely long, from a few days to a few weeks, and even in years and months, there is no limit to the region, and there is no obvious [touch] existence, it can be said that this is the real world.

As a result, the Dream Interpreter's goal here has also changed to a certain extent, and it is often no longer just to kill the Nightmare or kill a certain creature, or to escape from a certain place, or to help someone wake up, but the solution to the D-Class Nightmare has completely changed from an individual to a group, such as killing a group of creatures, or fleeing with a group of people, or even affecting the victory or defeat of a war.

Therefore, it is very rare to complete a D-level nightmare, and it is difficult to complete it even if the strength is not enough, even if the intelligence is superior, it is not a joke that 99% below the deacon level and about 90% above the deacon level are death, but the dream power increase obtained by completing it once is also very great.

Even if you want to be promoted to the Nightmare Rank, you must go through a Nightmare of Rank D and win.

In general, this is a martial arts arena for the strong to show their abilities, but for the weak, it is a hellish existence.

The above is the definition of a D-class nightmare in the textbook.

While thinking about these contents, Su Qin ran quickly, her current running speed is definitely at the superhero level, maybe not as exaggerated as a superhero like Flash, but it is still no problem to run within 5 seconds of 100 meters, and this speed can be maintained continuously, but with the current dream power value, even if she is in a D-level nightmare, I am afraid that she can support it for about half an hour with all her strength, and if it is slower, it can last longer.

Now the two of them have been running in silence for nearly fifty minutes, in such silence, Su Qin was able to experience the wonder of D-level nightmares, the dream power that could only recover from sleep in the past is completely different here, after Zuo Dao's mention, Su Qin, who ran the dream power line during the run, could even feel that there was some kind of energy in the air that entered the body with his breath, and finally turned into his own dream power, which was almost the same as the fighting energy internal force mana in fantasy novels.

If he stayed here long enough, Su Qin was completely confident that he could increase his dream power value to the current extreme, but even so, after running at Sadao's speed for 50 minutes in a row, Su Qin was still a little tired.

As for Sadao's indifferent appearance, there is no need to mention it, anyway, he has long been used to it......

The two of them were not just walking in a straight line along the way, Zuo Dao took three or four turns, and once Su Qin glanced at it with a spiritual probe, and there was a huge version of a centipede-like creature lying on his stomach, so this is probably the reason why he is running like a dog now, and this sewer does not seem to be a safe place.

The breathing has begun to feel hot, and the body is getting more and more accustomed to this state of running at extreme speed, a faint instinct self-regulates the body, but the recovery has completely failed to keep up with the consumption, and if you run for another ten minutes, you must rest, and you have to lose your strength in fifteen minutes.

Run, keep going.

Just like calculating Su Qin's physical fitness, Zuo Daokan stopped at fourteen minutes, and Su Qin at this time didn't care about his image, so he directly held on to the wall next to him and gasped, and he felt much more tired when he stopped after running at extreme speed, and the whole person was about to collapse.

"Come up, I'll carry you"

Without waiting for Su Qin to take two more breaths, Zuo Dao squatted in front of Su Qin in such a flat tone, unlike the imprint of the word 'Jing' that Su Qin could not inspire, the dark red Ouroboros behind Zuo Dao was still as vivid as the real thing, and each tiny snake had a perfect three-dimensional luster.

"There's still a little more to run, and you need to get out of this place quickly"

Squatting there, Zuo Dao added with his back to Su Qin.

"Hmm...... Hmmm"

After hesitating, Su Qin tried his best to suppress his chaotic breathing, and then carefully lay on Zuo Dao's back.

There is no distinctive smell, no warm warmth, he really feels like a machine.

"You don't have to suppress your breathing, it's not good for recovery"

"Got it......"

Sado first ran at a normal speed, and then in the next few seconds, the black jacket that Su Qin was wearing grew strangely like a living plant, and then wrapped her body inside in Su Qin's surprised gaze, and from the outside, it looked like a large black ball had grown on Sadao's back.

"It's good to look at the outside world with mental detection, I'm going to start speeding up"

After saying this, Sadao began to speed up explosively!

In Su Qin's hurriedly opened spiritual detection, almost everything around him turned into phantoms!

Hehe, what's there to see about the outside world...... My head is dizzy when I look at it, and I'm going to vomit if I look at it for a while......

After discovering that his nervous reflexes couldn't keep up with Sadao's running speed at all, Su Qin decisively ended his mental detection, and was simply wrapped in the line of running his dream power with all his heart, and quickly recovered himself.

Having said that, Sadao's ability is really convenient, I don't know if this product can build a high-rise building here on flat ground if it is needed?

After about ten more minutes, Su Qin began to excavate Zuodao's speed and slowed down, so he turned on the spiritual detection again, and the scene that caught his eye was......

"I'll ...... Flying......"

That's right, the position of the two of them is in the air now!!

Judging from the unclear vision of the surrounding area by the spirit detection, this is a super-large sewage treatment plant at all, and at this moment, the direction where the two of them are located is above the well where the sewage collects!

Sado just left the drain in a gliding position and rushed straight towards the opposite wall!

"Can really fly......"

Su Qin was completely stunned, could it be that Zuo Dao's ability was to fly? Or can you fly directly when you get here???

"See Clearly"

In this case, Zuo Dao actually had time to reply to Su Qin, but this sentence sounded directly in his mind.

"See clearly? Ay? It's ......"

Su Qin carefully contracted the spirit bundle and put it all around Zuo Dao, and suddenly realized that this guy Zuo Dao was really not flying, nor was he gliding, this thing was running!

That's right, there are several stones floating in the air at Sado's feet and in front of him, and because Sado is fast enough, he is already in a relatively stationary state with these stones, so he is simply running on the stones in the air!

Even that's too strong, isn't it...... Light power floating on the water is not so fierce...... And before he reached the air, he didn't feel any signs of slowing down in Sado, which means that some of the rocks were knocked out by the way he was running, so even if the stones were scattered in the air, this kind of reaction speed would be no problem even if the stones were scattered in the air.

In just a few seconds of Su Qin's emotion, Zuo Dao had already stepped on the last big stone, jumped directly to the opposite wall, and then stepped directly on the vertical wall with his foot in front of Su Qin's refreshed three views, and then the whole person jumped straight up!

It was a vertical wall, but at the foot of Sado, it seemed that the frictional gravity or something had lost its effect, so he stepped on the wall steadily, jumped up, stepped on the wall, jumped......

Well...... A little airsick......
