Just as Ning Beichen was about to give up on this fellow, he saw Abu swaggering back on its own, which made Ning Beichen’s titanium alloy dog eyes pop out.
"Abu, you can come back by yourself?"
Ning Beichen stared at it intently and asked.
"Of course, Master, it's not difficult."
The black flood dragon acted nonchalantly, which immediately infuriated Ning Beichen.
"Not difficult? If it's not difficult, why didn't you come back? Do you know how hard it was for me to find you?"
Ning Beichen cursed at the black flood dragon.
"Master, well, I was asleep."
Abu looked embarrassed, which further enraged Ning Beichen.
This guy actually had such an ability. It was no wonder he had been pacing like an ant on a hot pan, racking his brain for a solution to get them back.
And this black flood dragon actually told him it wasn't difficult. Wasn't this going to drive Ning Beichen mad?
"How did you get back?"
Ning Beichen could only suppress his anger and ask.
"Uh, this… we flood dragons have the ability to traverse space."
The black flood dragon said proudly.
After hearing this old geezer's words, Ning Beichen's blood pressure soared to the ceiling, and he wished he could stomp it flat.
"I'm not angry, I can't be angry. This old geezer is a flood dragon, completely inhuman. I can't ask too much of it."
Ning Beichen pacified himself inwardly.
Since everyone was found and safe, that was the greatest fortune.
"By the way, Master, when I was coming back, I saw something sparkling and I brought it back casually. See if it's what you're looking for."
At this moment, the black flood dragon took out a huge, sparkling, round crystal.
Ning Beichen's heart pounded, and he quickly took the round crystal to examine it.
He soon felt a tremendous amount of energy contained within the crystal. He immediately took the crystal to the slot in the flying vehicle and inserted it.
Two tendrils extended from the flying vehicle's slot and landed on the crystal. The crystal instantly glowed brightly, and the flying vehicle began to vibrate.
Ning Beichen's face showed immense surprise.
However, the flying vehicle only vibrated for a moment before stopping, and then there was no further movement.
Ning Beichen, as the owner of the flying vehicle, could check its status. The crystal could indeed replenish energy for the flying vehicle, but the amount was too small to activate it.
The main reason was that the flying vehicle had used up all its energy the last time it escaped from the Heavenly Venerable's pursuit, leaving no residual energy.
Even with this crystal, the flying vehicle could only recover a tiny bit of its vitality, not enough to wake up Ning Xiaoling.
"Abu, where did you find this kind of crystal? Are there any more?"
Ning Beichen immediately asked the black flood dragon anxiously.
"Well… there might be. I didn't pay too much attention, because I sensed some danger there and didn't dare to get too close."
The black flood dragon replied.
Ning Beichen knew the black flood dragon's strength well. If even it felt danger, then the danger must be significant.
But no matter how dangerous it was, Ning Beichen had to go find the crystals; otherwise, they would never be able to leave this place.
"Abu, can you still find that place?"
Ning Beichen asked.
"Yes, it's easy for us flood dragons."
The black flood dragon said proudly.
"That's great. Take me there. The flying vehicle needs more crystals to replenish its energy; one is not enough."
Ning Beichen said.
"Ning Beichen, count me in."
Chen Xingyun stepped forward and said.
"Ning Beichen, I'll go help too."
Luo Yingying also walked to his side and said.
"No, Master, Yingying, you can't all go with me. We need strong people to stay here in case something happens. How about this, Yingying, you stay here, and Master will go with me to find the crystals."
Ning Beichen thought about it and was still unwilling to let his women take risks.
"It's decided."
Before Luo Yingying could speak, Ning Beichen made the decision himself. Luo Yingying had no choice but to comply.
As for the black flood dragon Abu, frankly, neither Ning Beichen nor Chen Xingyun asked for its opinion.
Soon, Ning Beichen and Chen Xingyun sat on the black flood dragon Abu. Abu easily traversed the dimensional space with them, making Ning Beichen grit his teeth.
He had worked so hard to find a way to enter the dimensional space, yet this guy was sound asleep inside, causing him to worry endlessly.
The black flood dragon shuttled rapidly through the dimensional space, and soon it brought Ning Beichen and the others to the place where it had found the crystal.
The place looked like a black well in an abyss, and the crystal was inside that black well. However, the black flood dragon sensed a danger that could threaten it, so it didn't dare to get close.
But Ning Beichen and Chen Xingyun were fearless. Although Ning Beichen's cultivation didn't seem high, his true strength could rival a Venerable, and Chen Xingyun was at the peak of the Venerable realm.
"Black flood dragon, you wait for us here."
Ning Beichen and Chen Xingyun both left the black flood dragon and flew into the abyssal black well.
"Master, what exactly is this place?"
After Ning Beichen entered, he found that it looked like a large circular mine, with pitch darkness all around, and eerie, terrifying sounds occasionally echoing.
"Beichen, back off!"
At this moment, Chen Xingyun shouted, drawing his sword with both hands and slashing forward!
A sharp sword light seemed to cleave through the darkness, and Ning Beichen witnessed the power of a peak Venerable. This sword strike was definitely something he couldn't block.
With a swish!
The sword light plunged into the darkness, as if nothing had happened.
"Master, what is it?"
Ning Beichen asked.
"I don't know. I just felt something peeking at you ahead. Be careful."
Chen Xingyun said.
"Understood. Master, you be careful too."
Ning Beichen nodded and cautiously moved forward.
Before long, Ning Beichen also felt a sense of crisis on his right. Without thinking, he also slashed his sword.
"Master, there's blood on the ground. I should have injured it just now."
Ning Beichen went to the spot where he attacked, squatted down, and found a pool of blood on the ground, then said to Chen Xingyun.
"I don't know what it is. I feel this place is very strange; I've never encountered such a situation."
Chen Xingyun said.
"Master, I think this thing is somewhat similar to something I encountered before. I call such things 'ominous'."
Ning Beichen looked at the bloodstain on the ground, analyzed it for a moment, and then looked up at his master.
