Because there are a lot of monsters here and their strength is also very strong, and Yu Tianxiao and Lan Xing'er entered this cave for the first time, and they didn't know anything about the situation inside, so they didn't choose to fly, but walked into it little by little.

This time, they still carried the detector, and the accuracy of the detector was not only increased, but the detection range was also increased from 10 kilometers to 20 kilometers in the previous section. With a detector, you can predict the dangers that may occur in advance, so that they can prepare in advance to avoid the possibility of being attacked by monsters and getting injured for no reason.

Although they were walking, the two of them were still moving fast, and they traveled several kilometers in ten minutes. As the two of them continue to go deeper, the light inside becomes darker and darker, but with the super eyesight of the two of them, they still see every detail, not to mention that they still have a detector in their hands, so they are absolutely not afraid of any emergencies.

Just when the two of them had traveled about thirty or forty kilometers, suddenly, they couldn't help but hear a cry from the depths of the cave! Wow! Wow weird scream! The screams came and went, very harsh, and terrifying, and people couldn't help but have a creepy feeling when they heard it.

After hearing this cry, Yu Tianxiao and Lan Xing'er couldn't help but immediately set their eyes on the detector screen. However, when they looked at the detector screen, they couldn't help but be shocked to find that there was nothing on the screen.

Seeing this, Yu Tianxiao couldn't help but whisper to Lan Xing'er: "It seems that the location of the monster that made the cry is not within the range of the detector. ”

"What kind of monster, screaming from such a distance, we can all hear it?" Lan Xing'er couldn't help but immediately asked.

"I don't know, I've never heard such a cry before." Yu Tianxiao shook his head and said.

"I'm sure that a monster that can make such a loud cry will definitely not be an ordinary monster." Lan Xing'er couldn't help but guess.

"I think that's the same, okay! Let's stop speculating here. Let's continue to move forward, when we get to the place, it's all clear! Yu Tianxiao couldn't help but say.

"Hmm!" Lan Xing'er nodded, and then didn't say anything more.

So, while holding weapons in their hands and ready for battle at any time, the two continued to move forward.

I saw that as the two of them continued to move forward, the terrifying and piercing screams couldn't help but get louder and louder, five kilometers. Ten kilometers, fifteen kilometers, twenty kilometers ......, just when the two of them had traveled more than thirty kilometers further, the two finally found that there was a projection on the detector screen, but because the distance was too far, they couldn't see what it was at all, and they could only see a fiery red shadow moving non-stop. In this way, the two did not think much more, but continued to move forward cautiously.

One kilometer, two kilometers. Three kilometers ...... Five kilometers, when the two of them traveled to a distance of eight kilometers, they finally saw the object displayed on the detector screen.

It turned out that it was two huge fiery red monsters mating, and both monsters exuded a powerful aura of energy. According to speculation, the most important horse must be a king-level monster, and it may even be a king-level monster. And that's not all. One of the monsters also has a spherical energy emitter on its body.

After seeing the spherical energy emitter, Yu Tianxiao couldn't help but immediately exclaimed, "Vulcan Bead!" It turns out that they have Vulcan Orbs on them! ”

"Shall we go now, then?" Lan Xing'er couldn't help but ask softly.

"Why are you so unreasonable, people are doing good things, you can't wait for others to finish doing good things before you go?" Yu Tianxiao looked at Lan Xing'er and couldn't help but smile evilly.

"Nasty!" Hearing Yu Tianxiao's words, Lan Xing'er's face couldn't help but turn red to the base of her neck all of a sudden, and then she just said these two words.

"Hahaha, alright, let's wait here for a while, and then we'll go over when they're done, and let them have one last pleasure." Yu Tianxiao couldn't help but say.

"It's the first time I've encountered this." Lan Xing'er muttered softly.

"Who said no, if it weren't for the Fire God Bead, I would have left here immediately, and I would definitely not provoke them." Yu Tianxiao couldn't help but say softly.

"Then can we stop snatching their Vulcan Beads, anyway, this place is big, and there is more than just this one." Lan Xing'er immediately said.

"Don't rob them! That's not going to work, you don't want to be a woman at this time! Have you forgotten that the first law of survival in the universe is that the weak eat the strong, not to mention that they are beasts, and we are humans, and the two sides are not in the same camp at all. Again, the Vulcan Bead is a very rare treasure, think about it, if the Vulcan Bead is not rare, why did the Martial Arts Hall only let us get only twelve pieces per person within the three-month period? If we let them go when we see them mating this time, will we also let them go the next time we encounter two monsters mating? And what about the next time, and the next time, and the next time? You must know that there are countless monsters here, and you can see them mating in pairs anytime and anywhere, if the Vulcan Bead is still on these companion monsters, then won't we look for the Vulcan Bead? ”

Speaking of this, Yu Tianxiao couldn't help but pause, and then continued: "Because we have detectors in our hands, we will detect them in advance, and if we don't have detectors in our hands, then we will only find them when we get close." That way, when they notice us for the first time, they will stop mating at once, and then attack us with the most violent. At that moment, if our strength is stronger than theirs, but if our strength is weaker than theirs, then one million percent of us will become their mouths and stomachs! The road of the strong is extremely bumpy, we must be clear-minded, point to our heart, the good is good, the evil is evil, whoever stays will stay, the killing will kill, and the capture will be taken! There must be no indecision, otherwise we may fall at any time and lose our lives! Do you understand what I mean? ”

"I understand!" After listening to Yu Tianxiao's statement, Lan Xing'er nodded and replied softly. In fact, she understands these big truths, but when she really faces them, she can't bear it, after all, whether it is a man or a beast, a man or a woman, or a male or a female, everyone is a couple, a couple.

But then again, Tianxiao was right, if the two of them didn't have a detector, but directly encountered those two monsters mating, then those two monsters would definitely kill them quickly. It was precisely because of this thought that she finally replied that race to race, human and monster, may always be enemies who kill each other.

"Alright, let's wait a little longer, and we'll kill them as soon as they're done." Yu Tianxiao said again.

"Hmm!" Lan Xing'er just nodded and didn't say anything more.

In this way, the two sat on the ground together, snuggled up to each other and sat there, and as for the detector, Yu Tianxiao put it into the space ring.

Half an hour later, brush! Yu Tianxiao couldn't help but take out the detector again, and then immediately looked at the screen of the detector, this look, Yu Tianxiao couldn't help but be startled immediately, only to see that he quickly shouted to Lan Xing'er beside him: "Hurry up, get ready for battle, those two monsters are rushing towards us, judging by the breath, they may all be beast emperor level!" ”

"What, it's all Beast Emperor level?" Hearing this, Lan Xing'er also screamed, and then stood up with a brush, holding the Demon Blue Sword, ready to meet the battle anytime and anywhere, Yu Tianxiao was also holding the Star Slashing Sword and was ready for battle.

"They've been killed, ready to fight!" As soon as the voice fell, brush! Yu Tianxiao quickly put away the detector.

However, at the moment when Yu Tianxiao put away the detector, wow! Wow! With two piercing and strange screams resounding throughout the cave, boom! Rumble! I saw that in an instant, two huge and incomparably fiery red figures couldn't help but rush towards the two of them like lightning. (To be continued......)
