This ancient palace complex has a total of 101 floors, of which only the first floor is a huge basilica and supported by countless giant columns. From the second floor to the one hundred and first floor, each floor has one room after another, some rooms are large, some rooms are small, for example, the room where Yu Tianxiao got the life of the little golden ball was very large, and some small rooms were only a few dozen square meters. Depending on the size, these rooms are used for different purposes.

After searching all the rooms on the 77th floor, Yu Tianxiao and the others quickly entered the 78th floor, then the 79th floor, the 80......th floor, and continued to search upwards layer by layer.

However, even after they searched all the places from the 77th to the 87th floor, the 10th floor, they couldn't find any more treasures or anything special.

This time everyone was disappointed again, this palace building is really completely irregular, maybe something will appear somewhere, after the discovery of the small golden ball life on the 77th floor, everyone thought that the higher they go, the more surprises will appear, but the current result is not the same thing at all.

However, if one treasure can be found, it is possible to find a second treasure, so Yu Tianxiao and the others did not give up searching, but continued to search upstairs.

Just as they entered the 99th floor, suddenly, the detector's light came on and an alarm sounded. Seeing this, Yu Tianxiao couldn't help but be immediately startled, and then shouted with surprise on his face: "Finally, there is a new discovery, just 200 meters ahead, let's go over and have a look!" ”

Immediately, all the students followed Yu Tianxiao and walked in the direction indicated by the detector.

200 meters away, in a few moments.

When Yu Tianxiao led a group of people to the location of that item, in an instant, everyone was shocked!

I saw that above the end of this incomparably wide corridor, there was a transparent ball of light with a diameter of about six meters. While the transparent ball of light was suspended in mid-air, it continued to emit dazzling light in all directions.

"Bi Yuanjing!" When Yu Tianxiao saw the transparent ball of light, he couldn't help but immediately exclaim.

"What is this?"

"I don't know!"

"Looks like it's definitely not an ordinary treasure!"

……

Suddenly, after seeing the transparent crystal ball, some students began to exclaim and discuss.

Obviously, Yu Tianxiao's light call just now, the other students didn't hear it at all, for the energy crystal ball in front of him, Yu Tianxiao naturally knows everything about it, because when he was studying in the one-star school district, Pi Piduo often used his spare time to instill some knowledge in the universe to him, so for the understanding of the universe, Yu Tianxiao is a hundred times stronger than these native two-star students.

Biyuan crystal is a powerful energy crystal in the universe, it can appear in any form, it can be solid, it can be liquid, and it can even be vaporized. As long as it is flesh and blood life, it can provide energy for itself through it, and there will be no side effects, so it is a treasure that all flesh and blood life in the universe compete for.

Biyuan Crystal, as an energy crystal, can exist anywhere, that is, maybe you will find it somewhere in the universe. Those places can be underground caves, caves, caves, or some special cosmic secret realms, etc.

However, like this Biyuan Crystal actually appeared in the sea, Yu Tianxiao heard of it for the first time, and it was also the first time he had seen it! And still appear in this ancient palace building, which is even more incredible! If I didn't guess wrong, this Biyuan Crystal must have been brought here by someone, but now the people who brought it here don't know where to go!

Yu Tianxiao was secretly thinking to himself, suddenly, only to hear, there was a loud bang, and then he saw a room on the right side of the Biyuan Crystal Levitation, the door exploded violently, and in an instant, the metal fragments couldn't help but fly around! Then, with a whoosh, a monster came out of it.

I saw that this was a sea blue star beast with a height of more than ten meters and a body length of thirty or forty meters. This sea blue star beast has thick limbs, a long tail, a huge head and a huge mouth, and those two giant eyes are like two small planets, and its body is covered with hard scale armor.

At first glance, this sea blue star beast is an enlarged version of a crocodile, and even a bit like a pangolin.

When this monster rushed out of the big room, Yu Tianxiao and Lan Xing'er and their group couldn't help but be startled, and they all reflexively retreated far back before they stopped, and then formed a confrontation with the monster.

"Black-Armored Demon Scale Beast! And it's also a king! Oh, my God! How did we run into a king-level Blue Star Beast again, it's really terrible! Suddenly, in the crowd, a female student looked at the monster and couldn't help but exclaim loudly.

That's right, this is the famous black-armored demonic scale beast in the Blue Star Sea. The Black-Armored Demon Scale Beast is a Blue Star Beast with particularly strong attack power, and it is as famous as the Thief Emperor Beast that Yu Tianxiao killed earlier. Not only can it survive in the water, but it can also survive on land, and it can even fly, so it is definitely the king of the Blue Star Beasts.

I saw that after this black-armored demonic scale beast saw Yu Tianxiao and his party, it couldn't help but immediately say angrily: "Human, why do you want to come to me, is it to snatch my Biyuan Crystal?" ”

What, this is its territory, didn't the thief emperor beast that was killed by himself and Xing'er say that this is its territory? Thinking of this, Yu Tianxiao immediately understood that it must have been this black-armored demon-scaled beast that had already inhabited here, and the thief emperor beast had just come and hadn't discovered it.

Again, this palace building is so huge, it is impossible for only one Blue Star Beast to live here, so it is not surprising that there are multiple Blue Star Beasts here. Now, in addition to this black-armored demon-scaled beast, there may be other blue-star beasts here.

Although they had searched most of the area here, there were still two floors above that they hadn't found, and maybe those Blue Star Beasts were hiding on it. Thinking of this, Yu Tianxiao immediately turned around and said to all the students: "Everyone should be careful, maybe there will be other Blue Star Beasts here." ”

"Yes, Captain!" All the trainees immediately responded.

It's a bit sad that the detector they carry is not the most advanced, it's just an ordinary detector. This kind of detector not only has a small detection range, but also the detection function is not very strong, and it is impossible to detect a Blue Star Beast above the king level at all.

Because when the Blue Star Beast reached the king level or above, it could have the ability to shield itself, and when they felt the detection signal, they could immediately shield it, so when Yu Tianxiao and the others detected Biyuan Crystal before, they did not detect this black-armored demonic scale beast.

"What, that Biyuan Jing was brought here by you?" Hearing what the black-armored demonic scale beast said before, Yu Tianxiao couldn't help but immediately ask at this time.

"That's right, I got it from a dangerous place, and I almost lost my life for it!" The black-armored demon-scaled beast spoke.

"So that's the case, I said how could Biyuanjing appear in this sea." Yu Tianxiao said again.

"Now that you know it's mine, why don't you leave quickly!" As he said this, the black-armored demon-scaled beast no longer spoke, but suddenly opened its huge mouth and roared.

In an instant, when the black-armored demon-scaled beast roared out such a voice, boom! Airplanes! Suddenly, the strong sound shock wave slammed into Yu Tianxiao and all of them.

"Ahh My ears! ”

"My ears hurt too!"

"What is this?"

……

Suddenly, some of the students with poor resistance couldn't help but scream all at once, because the sound shockwave emitted by the black-armored demon-scaled beast was too strong! It also appeared too suddenly! None of us was defenseless, and they didn't have time to defend at all, so they were all hit, and Lan Xing'er was also hit, and my ears were deaf all of a sudden!

At this moment, among the 49 people in the group, Yu Tianxiao didn't get much hit, because his resistance ability was the strongest among all of them, and it was not ordinarily strong, so he withstood the sonic attack of the black-armored demon-scaled beast this time, but he also felt a faint tingling pain in his ears, but it was not obvious.

"Everybody cover your ears, or find a way to plug your ears!" At this time, Yu Tianxiao couldn't help but order loudly.

After hearing Yu Tianxiao's order, everyone immediately began to try their best to block their ears.

"Hahaha!" Seeing Yu Tianxiao and their group looking embarrassed for a while, the black-armored demon-scaled beast couldn't help but burst out laughing.

"Demon Scale Beast, you dare to carry out a sneak attack, see if I don't kill you!" I saw that as soon as Yu Tianxiao's words fell, he swished, held the Star Slashing Sword, turned into a streamer, and killed the black-armored demonic scale beast alone.
