In the following time, Yu Tianxiao continued to search for crystal flint with Lan Xing'er through the method of soul induction. Soon, they didn't need to spend much effort, nor did they have to fight fiercely with some powerful Blue Star Beasts, but they only spent six days searching for them, and they successfully found the five crystal flints again.

These five, plus the previous four, the two of them have found a total of nine crystal flints so far, which means that they only need to find three more crystal flints, so this third-layer promotion tower can be regarded as a successful pass.

On this day, they came to the foot of a large mountain. I saw that the mountain in front of me could reach straight into the sky, and the diameter could be said to be nearly 10,000 meters. The whole mountain is verdant, rocky, and steep, and you can hear the roar of beasts coming from the mountain from time to time.

At this moment, Yu Tianxiao and Lan Xing'er, who were standing at the foot of the mountain, were like two ants or even two grains of dust compared to the mountain.

Looking at the topless mountain in front of him, Yu Tianxiao couldn't help but whisper to Lan Xing'er beside him: "I can clearly feel that the crystal flint is on this mountain. ”

"I can feel it, too." Lan Xing'er also nodded and replied.

"This mountain is so tall and too big, it seems that it is impossible to walk up it!" Yu Tianxiao whispered again.

"What then?" Lan Xing'er couldn't help asking.

"Of course it's flying, I'll fly up with you on my back." Yu Tianxiao replied immediately.

"Fly! Can your injuries work? After hearing Yu Tianxiao's words, Lan Xing'er suddenly asked in surprise. Because she knew very well in her heart that after the battle with the giant scale beast, Yu Tianxiao was seriously injured, and although she had recovered a lot after these days, she still had not recovered.

"It's okay, my injuries are almost healed, maybe this time we will gather twelve crystal flints and break through this third-layer promotion tower, so we must fight!" Yu Tianxiao couldn't help but grit his teeth and said.

"Hmm!" Hearing Yu Tianxiao's words, Lan Xing'er immediately nodded heavily, that's right, there are still two days before the assessment deadline arrives, so they have no choice but to fight hard.

"Okay, Xing'er, don't think about it anymore, come up quickly!" Saying that, Yu Tianxiao squatted down.

"Hmm!" Lan Xing'er didn't hesitate, and immediately lay on Yu Tianxiao's back, and then hugged Yu Tianxiao's neck tightly.

When Lan Xing'er lay on Yu Tianxiao's back, he saw Yu Tianxiao swish, and his two toes touched at the same time, like an extremely flexible monkey, he immediately rose into the air, and then swirled in mid-air, and flew away looking for the source of soul induction.

Soon, they flew into a cave halfway up the mountain, but this cave was completely different from the cave where the fiery red giant was before, and the cave where the fiery red giant was located was a solitary cave with no branches at all;

But this cave is a hole in a hole, a hole in a hole, a big hole with a small hole, a small hole hidden in a big hole, and the holes are connected, just like a labyrinth.

After entering the main cave, Yu Tianxiao and Lan Xing'er still didn't find the shadow of the crystal flint, but the feeling of soul summoning was much greater, so the two of them did not stop, but continued to fly in the direction of the soul summoning sense.

They passed through cave after cave. Just as they flew into the sixth cave, suddenly, they heard a beast roar that shook the heavens and the earth. Syllable! After hearing the huge beast roar, Yu Tianxiao couldn't help but immediately brake sharply, and then stopped and fell to the ground in an instant, and at this time, Lan Xing'er also quickly jumped off Yu Tianxiao's back.

At this moment, they couldn't help but feel that the sense of soul summoning had been strong to the extreme, and it was obvious that the crystal flint was not far ahead.

Although I already know where the crystal flint is, it is not so easy to get it. I saw that just ten meters away from Yu Tianxiao and Lan Xing'er, there was a head more than twelve or thirteen meters high, almost covering the entire cave, with a golden horn on his head, and that golden horn was like a golden scimitar, shining with golden light from time to time. The skin of his body was as rough and hard as a rock, and his hooves were as thick as four pillars of heaven.

The only difference is that the horns of the rhinoceros are not golden, but the horns of this giant beast are golden, and the size of this giant beast is much larger than that of the rhinoceros.

"What a big one-horned spirit beast!"

"And it's a high-level beast general!"

When Yu Tianxiao and Lan Xing'er saw this giant beast, they immediately recognized the type, name and level of the giant beast.

The one-horned demon spirit beast is a relatively rare monster on the blue star, its attack is very strong, and its defense ability is also relatively strong, it is definitely a relatively difficult blue star beast.

The only weakness of this one-horned demon spirit beast is that it has very poor flexibility, basically similar to the old scalper on the earth, and even more stupid than the old scalper, so there is no other way to deal with it except to fight to the death. Only by pestering it, annoying it, making it hot-headed, and having a reduced sense of prevention, can it have the possibility of winning.

Looking at the high-level beast-level one-horned demon spirit beast in front of them, Yu Tianxiao and Lan Xing'er couldn't help but tremble and numb in their hearts! After a while, Yu Tianxiao couldn't help but say helplessly to Lan Xing'er: "Compared to that giant scale beast, this one-horned demon spirit beast is definitely inferior, it seems that this time we are really more than lucky." ”

"Yes! We've got another formidable enemy! I don't know if I'll be able to get the flint this time. Lan Xing'er also muttered.

"Fight! We only have two days left, so time doesn't allow us to look for other crystal flints, even if there is enough time, then who dares to guarantee that we will not encounter a Blue Star Beast that is more powerful than this one-horned demon spirit beast when we go to other places, if we encounter something more powerful and powerful than this one-horned demon spirit beast, then we will really cry and can't find a tune! Yu Tianxiao said to Lan Xing'er while looking at the one-horned demon spirit beast in front of him.

"Then what are we going to do with this one-horned spirit beast?" Encountering such a powerful Blue Star Beast Lan Xing'er is almost completely useless, not only this time, the first few times it was almost Yu Tianxiao as the main force, and Lan Xing'er was assisting on the side, so at this moment, Lan Xing'er couldn't help but feel completely overwhelmed, and could only listen to Yu Tianxiao, and Yu Tianxiao asked her to do whatever she did.

"The biggest weakness of this one-horned demon spirit beast is that it is stupid, short-tempered, and impatient, so the best way to deal with it is to stalk it, first annoy it, then lure it, tease it, lure it out of the cave, and then you take the opportunity to seize the crystal flint." Yu Tianxiao couldn't help but slowly said to Lan Xing'er.

"Good! I listen to you! Lan Xing'er did not hesitate, nodded heavily and said.

"But don't worry, I won't let you get hurt again this time, stay for a while and wait for me to lure this one-horned demon spirit beast away before you get on it!" Yu Tianxiao couldn't help but instruct.

"Hmmm! I know! Lan Xing'er nodded.

"Alright, let's get moving!" Speaking of this, Yu Tianxiao first paused, and then shouted violently: "Evil beast, send it to death!" ”

As soon as the words fell, I saw Yu Tianxiao make a noise first! Cast dozens of doppelgangers, and then swish! Sou! Sou! Sou! Sou! Sou! Dozens of clones rushed towards the huge one-horned demon spirit beast like a rain of lightning.
