"Let's take a look first!"

Liu Haoyu did not boast about Haikou, just in case he was slapped in the face.

In fact, when he first sensed this invisible barrier, he sensed that something was unusual.

In this era of the earth, there used to be cultivators, but in this era, because of the withering of the spiritual energy of heaven and earth, it has gradually declined.

However, Liu Haoyu felt that the invisible barrier in front of him was not a product of this era on earth at all.

Liu Haoyu groped with his hands on the invisible barrier, giving people the feeling of touching air.

At the same time, his mouth was also muttering to himself: "It's strange, how do I feel that this method seems to be left over from previous eras, a little familiar, which era is it from......"

Liu Haoyu, who is caught in reminiscence, has a bit of a brain pain, the time is too long, at least hundreds of millions of years ago, and now some things are very vague in retrospect.

Qiu Zhenghao, who was standing next to him, couldn't hear it very clearly, scratched his head and asked curiously, "Senior, what did you just say?"

"It's nothing, it has nothing to do with you!" Liu Haoyu replied indifferently.

I don't want to say more about this matter, there are some things that no one else understands except him.

For example, human beings on the earth today are not the first intelligent life on the earth.

In the billions of years he lived, the earth experienced at least six eras of intelligent life for some mysterious reason.

And that's just billions of years before he was born, and how many eras did the earth go through before he was born?

In short, Liu Haoyu knows in his heart that compared to other planets, the earth is a relatively special existence.

"Hey, it seems that the soft solution is not good!" After carefully inspecting it, Liu Haoyu sighed faintly.

This invisible barrier was part of a huge formation, and according to his observations, there were many places in it that were laid out in a way that was a little incomprehensible.

However, if it is forcibly broken, it will also be a big challenge.

This invisible barrier and all the formations in this place are a whole, interlocking, if you want to break through this invisible barrier, it is equivalent to breaking all the formations here.

It's not as simple as one plus one equals two.

After thinking about it carefully, Liu Haoyu turned his head and said to Qiu Zhenghao: "You go back first! ”

"Ah......" Qiu Zhenghao showed a look of disappointment, and asked unrelentingly: "Senior, can't I really watch from the sidelines?"

The reason why he came over was actually to see Liu Haoyu's methods.

The goal has not been achieved yet, and if this is going back, wouldn't it be equivalent to running for nothing?

What's more, the oxygen cylinder he brought with him when he came has also been used up, and in the absence of internal strength and oxygen, I am afraid that he will suffocate to death in the water before anyone can go out.

When he strayed into this place many years ago, his kung fu was still there, and his cultivation was not weak at that time, and he had mastered the turtle breath gong, which gave him the opportunity to go out.

Moreover, he almost hung up that time, and he was lucky in the end......

Seeing Qiu Zhenghao's very reluctant look, the corners of Liu Haoyu's mouth twitched, and he couldn't help but playfully say: "Are you sure you really want to risk your life to watch the excitement on the sidelines?"

Qiu Zhenghao replied in a weak tone: "Senior, if I can, I want to stay......"

Liu Haoyu smiled and said lightly: "Whatever you want, since you want to choose to stay, then if you are accidentally implicated, you can't blame anyone!"

"Senior, I understand! I'll be careful myself, I'll just stand behind and watch from afar. ”

As he spoke, Qiu Zhenghao hurriedly retreated some distance, between Liu Haoyu and the waterhole outside the cave.

According to his thoughts, if there was really danger in waiting, such as the cave collapsing or something, this position should be enough time for him to run back to the side of the water tank.

At that time, as long as you fall into the water, it shouldn't be a big problem!

"Forget it, I'll give you something. Liu Haoyu shook his head helplessly, shook his hand, and suddenly a small emerald green object came out of his hand and flew towards Qiu Zhenghao.

Qiu Zhenghao's eyes were quick, and he hurriedly took it.

After he glanced at it a few times, he couldn't help but show a puzzled look: "...... is this?"

Liu Haoyu didn't bother to explain, and said directly: "Don't care so much, just put it on your body and put it on your body!"

"Oh!"

Qiu Zhenghao nodded honestly, and then carefully stuffed the emerald green pendant into his inner pocket and put it close to his body.

After explaining Qiu Zhenghao's here, Liu Haoyu turned around and looked at the invisible enchantment in front of him.

After taking a deep breath, his fingers flickered, and a small silver flying sword appeared out of thin air, hovering in front of him.

This sword has been following Liu Haoyu for hundreds of millions of years, he is not an ordinary flying sword, but a fairy sword, which he named Qinghong Sword.

At the beginning, the Qinghong Sword was just a relatively good growth-type spiritual weapon, and after Liu Haoyu's continuous cultivation and further study, it finally evolved to the level of a low-grade immortal weapon.

I don't know how many resources have been wasted, and the total value can be worth several immortal weapons.

"This ......"

Qiu Zhenghao, who was not far behind him, had his pupils shrank suddenly, and his whole person was stunned.

"This ...... Is this the legendary flying sword? So ...... he is?"

Qiu Zhenghao's eyes froze on Liu Haoyu's back, and his breathing gradually became short.

He suddenly thought of a possibility, which belonged to the legendary existence.

Immortal cultivator!

After realizing this, Qiu Zhenghao suddenly understood in his heart.

No wonder!

His methods seem to be so powerful, and some of them are even far beyond the level of the grandmaster powerhouse, if it is an immortal cultivator, then everything can be explained.

"Terrible! I didn't expect that there really existed an immortal cultivator on the earth today, no wonder his appearance hasn't changed for decades......"

Qiu Zhenghao sighed in his heart, and he suddenly thought that since Liu Haoyu, an immortal cultivator, had appeared on the earth, there must be more other immortal cultivators.

At this moment, he had a feeling that the earth had become stranger, not quite the same as he imagined, and he didn't know what kind of shocking secrets were hidden behind it!

Just when Qiu Zhenghao was thinking nonsense, Liu Haoyu was already planning to make a move after making all the preparations.

I saw that his face was extremely cautious, and the flying sword suspended in front of him became the size of a normal long sword after a while.

He reached out and grasped the hilt of the sword.

Liu Haoyu took a deep breath, instilled all the true yuan power in his body, and slashed at the invisible enchantment in front of him......
