Yu Tianxiao and Lan Xing'er continued to fly forward over this valley, and at the same time, they used the detector to detect the surrounding energy fluctuations at all times.

Soon, brush! Brush! The two of them landed again at the mouth of a large cave. Since there were caves of all sizes here, and they had previously found a Blood Spirit Stone in the cave where the Blood Rock Emperor was hiding, and if there was a first one, there would definitely be a second and a third, so they still regarded these caves as the main search ground.

I saw that the big cave in front of me was bigger than the big cave where the Blood Rock Emperor was hiding before, the entrance of this cave was more than 800 meters high, and the width of the cave was more than 500 meters, which can be said to be definitely a super big cave.

Looking at this huge cave, Yu Tianxiao and Lan Xing'er couldn't help but feel a tremor in their hearts, such a huge cave, I believe that there must be a lot of secrets hidden in it, of course, with those secrets comes many dangers.

However, as the saying goes, if you don't enter the tiger's den, you can get the tiger! Often the most dangerous places are the places where there are great treasures. Although they came to complete the assessment task this time, as long as they could find all ten Blood Spirit Stones, then they could immediately return to Blue Star and then go on to complete the next task, but in the process of completing this set task, if they could find some treasures and then get their hands on them, it would be a beautiful thing, so why not?

Thinking of this, Yu Tianxiao couldn't help but feel certain in his heart, and then whispered to Lan Xing'er beside him: "Let's go, let's go into the cave and take a look, I hope we can get some other treasures in addition to the blood spirit stone." ”

"Hmm!" Lan Xing'er nodded immediately when she heard this.

Immediately, whoosh! Sou! The two of them quickly turned into two streamers of light and flew towards the huge cave.

The cave where the Blood Rock Emperor was hiding before was not only large, but also very tortuous, but now this big cave was extending in a straight line, like a huge straight line tunnel, so Yu Tianxiao and Lan Xing'er couldn't help but speed up quickly. So the further you go, the faster you fly, and when you fly to a depth of more than 100 kilometers, the speed of the two people has reached the fastest.

Although the speed of the flight was very fast, they were always staring at the screen of the detector in their hands, and they were extremely careful in their hearts, observing every movement here, but when they flew a distance of about 200 kilometers, they could not detect the slightest energy fluctuation.

However, this big cave is bottomless. At a glance, it is estimated that there are more than a thousand kilometers, so Yu Tianxiao and Lan Xing'er did not make any stops, but continued to fly forward quickly. In this way, the two continued to fly forward for more than 100 kilometers, and at this moment, they were more than 300 kilometers away from the entrance, which can be said to have reached an extremely deep depth.

Just when they wanted to continue flying, suddenly. They couldn't help but be surprised to find that there was a division of power in the cave, and there was a division cave on each side of the main cave. Among them, the right side of the cave is more than 400 meters high and more than 200 meters wide. The entrance of the cave on the left side is more than 500 meters high and 300 meters wide.

Looking at the two huge caves on both sides, Yu Tianxiao and Lan Xing'er couldn't help but hesitate immediately, because at this moment. They don't know which cave to go into. At this time, Yu Tianxiao couldn't help but ask Lan Xing'er softly, "Which cave do you say we should go into?" ”

After listening to Yu Tianxiao's question, Lan Xing'er thought about it first. Then he couldn't help but say, "I think it's better to continue walking this main cave." ”

"That's good! This time, I will do as you say, I hope you have made the right choice! Listening to Lan Xing'er's words, Yu Tianxiao couldn't help but smile.

In fact, when the two of them were on a mission together, in most cases, Yu Tianxiao made the decision, and Lan Xing'er just acted according to orders. However, there are also some cases where Yu Tianxiao gives the right to choose and decides to Lan Xing'er and lets Lan Xing'er make the decision.

Yu Tianxiao is not a machismo, the reason why he is in charge most of the time is because he is much stronger than Lan Xing'er, and secondly, because Lan Xing'er is more attached to him and trusts him, so he always takes the initiative to hand over the decision-making power to him and let him exercise it.

In this way, after the two of them made a decision, they continued to fly along the main cave inside.

However, just as they flew to a depth of more than 500 kilometers, another sub-cave could not help but appear around the main cave, and it was a full eight sub-caves. I saw that these eight sub-caves were about the same size, and they were all half the size of the main cave. Seeing that so many caves appeared at once, the two of them not only hesitated, but also exclaimed: it seemed that they had walked into a huge labyrinth this time.

Not only that, but what made them feel even more strange was that until now, the two of them had entered half the depth of this big cave, but they didn't notice a trace of energy fluctuations, could it be that there was nothing in this cave at all? In this way, the two of them looked at these big caves and couldn't help but be suspicious for a while.

Just when the two of them were at a loss for which way to go, wondering why there was no trace of energy fluctuation in these big caves, suddenly, the detector in Yu Tianxiao's hand couldn't help but start sending out bursts of alarms. Hearing the alarm, Yu Tianxiao immediately set his eyes on the detector screen, and this look couldn't help but startle Yu Tianxiao.

I saw that there were eight points of light on the screen that were constantly flying towards them, and what was very strange was that the location of those eight points of light was the eight sub-caves around the main cave, and there was exactly one point of light in each cave.

As those eight points of light flew closer and closer, Yu Tianxiao couldn't help but immediately find that those eight points of light turned out to be eight figures, judging by the energy fluctuations displayed by the detector, everyone's energy fluctuations were very strong. Seeing this, Yu Tianxiao couldn't help but immediately shouted to Lan Xing'er: "Xing'er, retreat quickly, someone is killing us!" There are eight of them, and all of them are very strong! ”

"Yes!" Lan Xing'er was shocked at first when she heard Yu Tianxiao's words, and then immediately responded.

As soon as the words fell, whoosh! Sou! Yu Tianxiao and Lan Xing'er quickly turned around, and then turned into two streamers and flew wildly towards the original road.

Bian Feiyu Tianxiao couldn't help but smile at Lan Xing'er: "It seems that your choice is not good?" ”

"How did I know it would happen!" Lan Xing'er said with some disappointment.

"It doesn't matter, our detectors are earlier than them, they are still some distance away from us, run away, I hope you don't be caught up by them, otherwise it will be another fierce battle." Yu Tianxiao couldn't help but sigh.

In this way, the two of them couldn't help but fly towards the direction of the cave entrance at high speed.

However, just as the two of them flew away, whoosh! Sou! Sou! Sou! Sou! Sou! Sou! Sou! Sou! In the blink of an eye, the figures of Badao, tall or short, burly or thin, handsome or ugly, immediately appeared in the main cave.

After all the eight figures gathered together, one of the tallest men with a relatively handsome face said, "Brothers! I just sensed that two people had entered this cave as well. ”

"I feel it too!"

"Me too!"

"That's right, I sensed it too, so I rushed back immediately!"

……

They all said the same.

"Based on my detections, they may have fled back along the main cave!" The tall burly man said.

"Then we, whether to chase or not!" Another of them asked.

"Of course chase! Maybe they'll have a lot of treasure on them, so let's go now! A little later, they'll probably be gone! The tall, burly man said. And then swish! The first one turned into a streamer and chased in the direction where Yu Tianxiao and Lan Xing'er fled.

Immediately after, whoosh! Whoosh! Several others immediately followed, and they all chased away as fast as they could, heading towards the entrance of the main cave. (To be continued......)
