In the room, Ling Yu sat quietly on the bed, his eyes closed, and a stream of spiritual power visible to the naked eye quickly gathered around him, and when it came into contact with his body, it would be strangely devoured, and later, a vortex of spiritual power was formed.

After Ling Yu was controlled by the sword spirit, his temperament became a little irritable, but at the same time, he also had some benefits, that is, the speed of devouring the spiritual power between heaven and earth.

According to the past, after he devoured the spiritual power, he had to carefully remove the impurities in it, but now, he didn't care about this step at all, and the speed would naturally be much faster.

Actually, this function should have been possessed after he devoured the Nether Blade, but at that time, the Sword Spirit did not recognize him, so he did not obtain this ability until now.

After an hour, the spiritual power around him faded a lot, and he remembered the mysterious black hole in his heart, so he stopped cultivating, his closed eyes slowly opened, and he followed out of bed.

There was no one else in the room except Ling Yu, and Mr. Long did not shy away from suspicion, he flashed out directly, and said lightly: "Boy, this black hole may not be as simple as you think, are you really going to go down?"

Ling Yu didn't expect him to give such an evaluation, so he couldn't help but be stunned for a moment, but then he laughed and said, "This was my home, and with what I know about my father, he will definitely not put anything harmful here." ”

"Hmm. Mr. Long nodded, "This is also true, but it is better to be careful, I always feel that there is something extremely dangerous down there." ”

"Extremely dangerous stuff?"

Ling Yu stood at the edge of the black hole, opened his head and looked inside, and at the same time, he separated a spiritual force and probed towards the black hole, but after a while, he did not encounter any obstacles, nor did he perceive anything that could be called dangerous.

"I don't know how deep this hole is, let's go down and have a look first, it doesn't seem to be useful to probe like this. In the end, Ling Yu withdrew his spiritual power and set his eyes on Mr. Long.

Mr. Long pondered for a moment, then nodded, and said, "My so-called danger is actually just my feelings, if I miss something because of this, it will be worth the loss." ”

"Something?" Ling Yu's eyes revealed a frenzy, "It can't be that my father left the garden......, right?"

Before his dream was finished, Mr. Long had already swept into the ring quickly, and said urgently, "Someone is coming." ”

The man's footsteps were loud, and Ling Yu didn't need him to remind him. Then, with a bang, the door was pushed open, and Xiao Min's handsome face appeared at the door.

"It's good that you haven't gone down yet. Xiao Min breathed a sigh of relief and said, "Who were you talking to just now?"

"I didn't ...... No one. Ling Yu avoided his gaze and said, "I was speculating about what was down there, and I unconsciously started talking to myself. ”

It was reasonable for him to say this, so Xiao Min didn't say anything more, and the two of them prepared again, and went down into the black hole.

The two of them walked in a somewhat dark black hole, both unconsciously tightened the clothes on their bodies, and after walking for a while, Ling Yu stopped and said, "Xiao Min, why don't you go up and wait for me, the cold here comes from the depths of the crypt, I don't know what kind of impact it will have on the body......

Xiao Min didn't wait for him to finish speaking, his face sank, but he didn't speak, and walked down the stairs directly. Ling Yu glanced at him, and in the end, he could only shake his head helplessly and hurriedly followed.

Walking down the stairs, after only a cup of tea, the cave was so dark that he couldn't see anything, Xiao Min took out an arm-thick candle from his arms, but after looking for a long time, he didn't find a fire fold on his body.

Ling Yu smiled, stretched out his right hand and snapped his fingers above the candle, and then there was a pop, and the candle was magically lit.

The light of the candle was slightly faint, and after walking for a while, the stairs were already at the end. At this moment, Ling Yu noticed that in the depths of the dim crypt, a bright light suddenly appeared.

The two of them paused, then glanced at each other, and then mobilized the fighting spirit in their bodies at the same time, they are not careless people, although their strength is not weak, but in this kind of place where they don't know the details, they will only be more cautious than usual.

When everything was ready, the two of them took another step, but before they had taken a few steps, they had just turned a corner when they stopped again, for they found that the low crypt in front of them had become a huge cavern.

The area of this cave is extremely huge, at least about a hundred zhang, and it is much more spacious than the Demon King Mansion above.

Xiao Min took a breath and said, "Is this cave man-made or natural?

Ling Yu looked at the night pearls inlaid on the top of the cave, shimmering like stars, and said lightly: "Nature alone can't produce so many night pearls. ”

"That's right. Xiao Min replied with a solemn expression, but then said, "But there are too many night pearls here, even in the palace, it is impossible to have so many here, how can there be here?"

"Ignorant boy!" Mr. Long snorted coldly in Ling Yu's heart, "This is a fisheye stone, it has no value at all, this is what the fish-eyed bastard is talking about! I can't even recognize it in the royal family, if it's a businessman, I will definitely lose so much that I won't have any pants left!"

"Then how does it glow?" Ling Yu said.

"There must be a secret passage to the outside world in this cavern," said Mr. Long unhurriedly, "and the reason why they shine is because there is a passage that refracts sunlight." ”

Ling Yu suddenly came to his senses, but he didn't bother to explain to Xiao Min, and he didn't want to say anything when he saw the fascination on his face.

Ling Yu looked around, and finally locked his gaze in the center of the cave, and Xiao Min on the side noticed that his pupils unconsciously shrank.

He followed Ling Yu's gaze and saw a deep pit of about ten zhang, which was like a fountain, but it was not spraying water, but a black substance like a thick fog.

Ling Yu felt that the reason why there was cold air in this place was all because of the substances that spewed out of this deep pit.

For the rest, there's nothing special here.

"Boy, you're in luck!"

Mr. Long's voice sounded again, but this time it was with obvious joy.

"Luck?"

Ling Yu didn't understand what he meant.

"Not bad. Your physique is much stronger than that of ordinary Dou Ling powerhouses, but you are not the strongest, and if you encounter a demon beast of the same strength, you will suffer. And this crypt cold is just right to temper your body. ”

It was rare for Mr. Long not to lose his temper and patiently explained.

"So what are you waiting for, let's start now. ”

Ling Yu didn't wait to finish speaking, he couldn't wait to walk over.

"Wait! I need to prepare something!"

Mr. Long gave him a big roll of the eyes, and then said angrily.
