The black dragon flew rapidly in the darkness. It was flying normally at first, but when it passed over a valley, it suddenly seemed to be attacked, and it fell from the sky.
Ning Beichen and the others on the black dragon's back also felt something was wrong. Ning Beichen immediately took out his bronze ancient sword, forming a funnel-shaped sword energy around them, protecting Liu Yilin and the others within it.
With a loud bang!
The black dragon crashed into a mountain peak, smashing a huge pit into the mountain.
"Old Hei, are you alright?"
Ning Beichen quickly asked it.
However, the black dragon only responded with pained sounds, unable to even speak.
Ning Beichen and the others quickly checked. They were shocked by what they saw.
A wound about five meters long was on the black dragon's abdomen, looking like it was cut by a weapon, such as a sword.
But they hadn't seen an enemy before, and even the black dragon had no warning.
"Everyone, be careful."
Ning Beichen instructed them to stand back to back, not to separate, and to take the antidote.
Then, he examined the black dragon's wound while paying attention to his surroundings. However, the surroundings were filled with poisonous mist, and it was also dark, so Ning Beichen couldn't see clearly. But he was sure that something had attacked the black dragon just now.
After all, illusions could be deceiving, but the wound was real.
"Old Hei, are you feeling any better?"
Ning Beichen had applied medicine to the black dragon, but it wasn't very effective and couldn't heal the wound, so Ning Beichen couldn't help but worry.
Although the black dragon's overall strength was not as good as his, in terms of individual strength and experience, the black dragon was not inferior to him.
However, if even the black dragon couldn't detect the enemy, it meant the enemy was extraordinary. Therefore, Ning Beichen not only worried about the black dragon but also about Liu Yilin and the others.
After all, their strength was far inferior to the black dragon's.
"Master... Master, I... I feel a sense of death, it's... it's invading my... my heart..."
The black dragon replied intermittently, showing that its condition was very bad.
And the most crucial thing was that Ning Beichen couldn't focus all his attention on helping it now, because the safety of Liu Yilin and the others was much more important to Ning Beichen than the black dragon.
At this moment, Ning Beichen suddenly had a fleeting premonition. His hair stood on end, and without thinking, he thrust his sword towards Haitang's direction.
Haitang was startled and froze on the spot. Even Liu Yilin and the others thought Ning Beichen was going to kill Haitang and cried out to stop him.
"Beichen, no, she's Haitang!"
"Ning Beichen, stop quickly..."
But their voices were not as fast as Ning Beichen's sword.
Before their voices had even fallen, Ning Beichen's sword was already in front of Haitang.
Just as Haitang was about to be struck by Ning Beichen's sword, a scream came from Ning Beichen's sword. Then, Ning Beichen's sword was dripping blood. However, what was strange was that Ning Beichen's sword had not hit Haitang.
But this was not the strangest part. The strangest thing was that Ning Beichen's sword was clearly empty, yet it was dripping blood, and there was that scream just now. It was obvious that Ning Beichen's sword had hit something.
At this time, the terrified women realized that Ning Beichen was not trying to kill Haitang, but was dealing with something bizarre.
"I'm sorry, Haitang. I suddenly had a premonition that something was approaching you, and the situation was urgent, so I didn't have time to warn you."
Ning Beichen held his sword and observed for a while. After not finding the thing again, he explained to Haitang.
"It's okay, I know you wouldn't kill me."
Haitang replied.
In fact, she was not scared because she thought Ning Beichen wanted to kill her, but rather it was a natural human instinct.
"How could I bear to kill you? I would rather kill myself than hurt you. Even if one day you fall into evil, I, Ning Beichen, will fall into evil with you. I will never make a move against you."
Ning Beichen said with a resolute voice.
Although there were no sweet words, Ning Beichen's words were the best promise and love confession to them, moving them to tears.
However, this was not a good time for public displays of affection. Although Ning Beichen had injured that thing based on his feeling, it hadn't died and could appear at any time.
And how many were there?
How strong were they?
These were all unknown factors.
At least the black dragon had been injured, which showed that these things were not weak, and might even be much stronger than them.
Ning Beichen was not being modest, because this was Xidu World, a paradise for cultivators.
Moreover, the black dragon was injured, and its condition was not optimistic. If their aircraft were here, Ning Beichen would have already left this cursed place.
But now, the most important thing was to ensure their own safety first, and then to save the black dragon. Dealing with those things could wait.
"Beichen, could these invisible things be in stealth mode?"
At this moment, the women had also calmed down and started to speculate.
"No, if they were in stealth, they wouldn't be able to escape my eyes, and I didn't sense any power other than ours."
Ning Beichen thought for a moment and said.
"Not stealth, then what exactly are they?"
Everyone began to ponder, because they all knew that if this matter was not resolved, they would be in a very passive situation, and Ning Beichen would not be able to save the black dragon with peace of mind.
"Dimensions. It's dimensional superposition. There exists another dimension in this world."
Just then, Liu Yilin spoke.
Hearing Liu Yilin's words, Ning Beichen's eyes lit up, because her guess had a high degree of credibility. If it was a superposition of another dimension, or creatures from another dimension, then they would naturally not be able to see their traces in this dimension, which would give them the illusion of being invisible.
"Yilin's guess is very likely. I will now set up a dimensional array. If it is as Yilin said, then within the dimensional array, those things will have nowhere to hide."
Ning Beichen said while starting to set up the dimensional array.
Speaking of which, this dimensional array was inspired by Ning Beichen from the Celestial Path. Otherwise, he really wouldn't have come up with any good solutions, and could only have taken everyone to forcibly evacuate this place.
Setting up a dimensional array was not easy, nor was it an ordinary array technique. Ning Beichen needed to enter the Zhou Tian Road to set it up, which gave Liu Yilin and the others a very strange feeling.
In front of them, Ning Beichen was only a shadow, with no physical form. Even if they reached out to touch him, their hands would pass through Ning Beichen's body without being able to touch him.
