"Is there anyone up ahead?" Caterina asked, leaning on Sun Xiyun's shoulder. [Ran^Text^Library] []

"I don't know, but I vaguely hear a noise ahead, probably the guy we're looking for." Sun Xiyun nodded and said.

Then he said, "I'll let you down first, you wait here, I'll go over and have a look." ”

With that, Sun Xiyun walked to a corner at the bottom of the cave, put Caterina down, and let her rest against the wall for a while, and this is a corner, so she can hide herself a little, so that it will not be so dangerous.

"I'll go with you, I'm actually ...... Actually, it's okay already. After Caterina herself got off Sun Xiyun, she couldn't help but say.

"Huh? It's okay? Sun Xiyun pretended to be surprised and asked, in fact, she already knew that Caterina was pretending, and she had already been treated by Sun Xiyun, so she would definitely be fine, but the two of them had their own thoughts in their hearts.

Now that Caterina has spoken out, it would be good for Sun Xiyun to cooperate with her.

"Well, of course it's okay, you've been carrying me for so long, and you've rested for so long, so the injury on your foot has long been healed." Caterina nodded.

"Hmm...... Try to see if you can go. "Sun Xiyun cooperates with Katarina, do you have to do a full set of plays?

"It's really okay." Caterina said as she ran around Sun Xiyun a few times.

"Hmm...... That's right, okay, then you follow me, don't get too far, don't get too close. Sun Xiyun nodded and said to Katarina.

……

With Katerina, he quietly walked towards the front, there should be a turn in front of him, and he didn't know what was going on in front of him for the time being.

The two of them pressed against the wall and quietly touched it.

The people inside didn't know what they were doing, and they didn't seem to notice that the two had approached them.

Sun Xiyun touched the corner, secretly stretched out his head to glance inside, and immediately retracted his head.

He saw that it was a large hall like a large square, the space was quite large, and there seemed to be a lot of people in it, not to mention a dozen or so, and they were all wearing white robes, and a group of people were gathered together, I don't know if they were tinkering with something.

"What's going on inside?" Caterina put her lips to Sun Xiyun's ear and asked quietly.

"I don't know, there's a group of people inside, gathered around and don't know what they're tinkering with." Sun Xiyun also said with the appearance of Katarina, but when he was so close to her, he asked about the fragrance coming from her, and Sun Xiyun couldn't help but feel a little.

Immediately shook his head, put aside the cluttered thoughts in his mind, this is not the time to play hooligan, a little careless, it may be fatal.

"So what do we do now?" Caterina didn't seem to notice Sun Xiyun's strange appearance, but asked.

"Uh...... I don't know very well, but when I look at it, I don't know if there are any guards inside. Sun Xiyun thought for a while and said.

"Okay."

Saying that, Sun Xiyun quietly poked his head over again, this time he didn't dodge it directly, but looked at it carefully and secretly for a long time, and he found that there didn't seem to be guards here, in fact, after all, at such a long distance, and hiding so deep underground, no one would generally find out.

Therefore, it may be the person Sun Xiyun is looking for, plus the giant python is basically enough to guard here.

However, what made Sun Xiyun curious was that the person didn't know that the giant python had been injured by himself, as usual, he should have been waiting for him to come over, seeing that he was still busy here and was defenseless, what was going on.

Sun Xiyun was going to turn around and ask Caterina to rush in together, but now that these people have not reacted, it is the best time to be hungry, and these people are wearing white robes and are obviously some scientific researchers.

It's just that Sun Xiyun was just about to go out when he suddenly heard a voice.

"Are you ready? Is there a good place to start? ”

It was a man's voice, and the voice sounded a little dull, in short, a little weird.

Just when Sun Xiyun was strange, a man walked over from the direction blocked by the crowd, a man with a silver mask, only the upper half of his face was exposed, and the lower half was blocked.

And the figure of this person, Sun Xiyun recognized, was the man found in the surveillance before, that is to say, this is the person who killed Sun Xiyun's brother and rescued the Zhu family's father and son.

Sun Xiyun couldn't help frowning, but now was not the time to act rashly, he added a spell to block the aura to himself and Katarina, isolating the aura from the environment here.

In fact, it's a little late now, but there is an inexplicable strange power in this cave, because he has been interfering with Sun Xiyun, so he has always kept his body on alert, which is tantamount to hiding half of himself.

Generally, as long as you don't deliberately investigate, you won't find Sun Xiyun's existence, not to mention that if you want to detect Sun Xiyun's existence, you still need a certain amount of strength.

This man's strength, judging from the calculation and analysis of the superbrain, is definitely not enough.

I just don't know if he hid his strength.

……

After hiding the aura of himself and Katarina, Sun Xiyun continued to see what they were studying.

The man was still discussing something with a group of people in white coats, and he didn't notice the situation on his side, and he couldn't help but breathe a sigh of relief.

……

"Forget it, let's do it first, it just so happens that I have these two experimental questions, let's do an experiment with them first, and if it doesn't work, you won't get any results if you argue like this for a long time." The man suddenly interrupted the group of people in white coats who were arguing.

"This ......"

The group of people in white coats looked at each other, you look at me, I look at you, and finally they all nodded and said, "Okay." ”

"Okay, go and get those two people out." The masked man casually pointed to the two young men in white coats.

"Yes, sir." The two men said respectfully.

It is estimated that the person in this white coat has relatively shallow qualifications, and his status may not be very high, so he can see it at a glance.

After a while, two people were brought out, and these two people were from time to time, that is, the father and son of the Zhu family, and now their hands were tied and pushed out by the two young people.

"You two, you're almost rested, and you've almost done what I promised you, can you agree to my request?" The masked man looked at the father and son of the Zhu family, and said with a smile on his clothes.

The father and son of the Zhu family glanced at each other, and couldn't help but nod helplessly, the two of them had already seen the man's power, and they didn't resist at all, so it was better to agree.

"Ok, smart, hurry up and prepare." The masked man glanced at a few white coats standing next to him and said.

"Yes, sir."

Sun Xiyun stared at the masked man silently, really not knowing what experiment they were doing.

However, he didn't say anything, just wait and see.
