In the cave, Xu Chen threw out his hand in anger.

Deep underground, the white-haired man exclaimed, "Damn! Your turtle shell has collapsed!"

At the same time, the green-haired man opened his mouth and spurted out a mouthful of blood, and the green on his face became lighter and lighter.

The white-haired man's expression changed drastically, and he asked with concern, "What's wrong with you?"

"Can't die!" the green-haired man raised his head, the green on his face became lighter and lighter, and gradually, even his facial features became blurred.

"Are you okay?" the word "king" on the white-haired man's forehead became a little distorted.

"I can't bear this injury now......"

"Do we let such a powerful person in?" Looking at the huge cave on the stone wall formation, which was rapidly collapsing, the white-haired man looked dazed, and then exclaimed after a while: "No! How can there be people who can do this in these years?"

"No, it's not human......! It's a toxin!" the green-haired man's blurred face was extremely shocked, and his hands quickly pinched.

Seeing this, the white-haired man hurriedly asked, "You want to remove the ruins?"

"How can I withdraw?

With remnants of blood hanging from the corners of his mouth, the green-haired man quickly struck a spell towards a certain part of the stone wall, and then the light on the stone wall began to change, and the dazzling light combined into a difficult and difficult pattern.

"Do you want revenge?" The white-haired man said with obvious anger, and his brother, who had been with him for nearly 10,000 years, was hit hard by this, so he naturally wanted to be angry.

The green-haired man shook his head slowly, but there was a hint of joy in his voice that he hadn't seen for a long time: "Revenge? No! There is something more valuable than revenge!"

"We've been waiting for a lot of years...... Hopefully!"

In the dark cave, Xu Chen, who had thrown his hand and thunder, was driving the locomotive to escape from the collapsing ground.

"Look, there's a hole there!" Yang Ziyun behind him suddenly shouted.

Xu Chen smiled to himself and said, "Look, there is a way out!"

With that, he set up a locomotive and rushed into the hole.

Deep underground, the white-haired man suddenly said, "You're going to lure them over?"

The green-haired man chuckled, "Are you going to let them run?"

The white-haired man pondered for a moment and asked very seriously, "How sure is it?"

"It's very big!" said the green-haired man with a determined expression, "You forgot? I was injured in the same way back then!"

The white-haired man nodded and said, "In this way, it is worth opening the formation." ”

"Get ready!" said the green-haired man.

A trace of doubt flashed in the white-haired man's eyes, and he smiled: "It's just two hairy children!"

The green-haired man shook his head slowly, and said very seriously: "Ordinary hairy children can't do this!"

"Alright then!" the white-haired man agreed, his expression still relaxed.

Xu Chen ran all the way along the tunnel in the cave, and the joy of finding a way out at the beginning had disappeared, and he turned his head and said solemnly: "Fill up the bullets!"

Feeling Xu Chen's solemnity, Yang Ziyun quickly put her hands and asked, "Something?"

Xu Chen nodded and said, "The road has been going down, maybe we are going to see the big guy!"

"Good!" it didn't take long for Yang to finish filling the ammunition.

The tunnel is getting steeper and steeper, Xu Chen has released the accelerator, but the speed of the locomotive is still getting faster.

"Quick, activate the runes on your armor!" Xu Chen said loudly.

Yang Ziyun immediately exported the aura in her body, and the black armor on her body immediately burst into lightning.

This is the customized armor that Xu Chen handed over to Yang Ziyun on the way to chase just now, and it is precisely because of the protection of this armor that he can repeatedly defend against the siege of many monks' flying swords.

At this moment, the situation was urgent, and after Xu Chen reminded him, he quickly slapped on the armor on his chest, and the rune was activated.

Yang Ziyun is a monk, and his armor is just a satisfying magic weapon, but Xu Chen is different, after all, it is just a foreign object.

The tunnel almost became a straight line, Xu Chen quickly slapped on the control board at the front of the locomotive, the mechanism and the runes were touched, and the huge locomotive quickly became smaller.

Xu Chen was about to grab the locomotive that had turned into a small iron box, but unexpectedly, a gust of wind came out of thin air, and the small iron box flew downward.

"It's coming!"

Xu Chen was startled, shouted, didn't care about the locomotive, grabbed the pistol with both hands, and was ready to go!

There were two soft sounds, and the two people with flashes on their clothes and armor landed lightly.

As soon as his footsteps were steady, ignoring the dust scattered around him, Xu Chen shot quickly, followed by Yang Ziyun.

After a few gunshots, the dust began to clear.

As far as you can see, you will see the crystalline stone walls that are round all around.

"This ...... This is the spiritual vein!" "Cultivators always remember it, and although they have never seen the real thing, it is not difficult to judge it.

"The little girl reacts quite quickly, but her knowledge is still a little worse!"

With a chuckle, Xu Chen quickly turned around and shot again at the place where the sound came from.

"Hehe, why are you more anxious than me, this kid? Without saying a word, you attacked without a head?" The white-haired man played with a few bullets in his hand and smiled playfully.

Xu Chen raised his eyes at this time, but saw that on a round stone altar, two people really looked at the two of them with interest.

The huge stone altar is divided into black and white, separated by an arc in the middle, with a white spot in the black and a black spot in the white.

The two sat cross-legged on black and white dots.

"Taiji Diagram!" Xu Chen was slightly startled.

Suddenly, the white-haired man sitting cross-legged at the white fish eye on the side of the black yin-yang fish showed a shiny look in his eyes and said in surprise: "Do you know this formation?"

Xu Chen was stunned, and quickly wiped away the shock in his eyes, squinted at the two of them, and pointed the pistols in both hands at the two of them.

Seeing that Xu Chen was reluctant to answer, the white-haired man had no choice but to change the topic and asked with a smile: "There is obviously another such thing in the weapon in your hand, why didn't you use it all just now?"

Xu Chen still didn't answer, but there was a trace of doubt in his eyes.

The white-haired man smiled slightly and explained, "Phantom squid, if you don't think about it, you really don't remember this thing!"

As he spoke, he turned his head to look at the green-haired man next to him and asked, "You are mixed in the water, do you have such a little brother under your command?"

The green-haired man said very seriously: "I'm not a rag collector!"

Xu Chen ignored the double reeds of the two and spoke for the first time: "This is your territory, so naturally I can't hide it from you!"

The reason why I opened my mouth was just to confirm one thing.

However, the two on the other side have already lived for tens of millions of years, so how can this kind of trick work.

The two sides began to be silent, and Yang Ziyun suddenly asked, "Senior, I don't know where the younger generation's knowledge is shallow?"

The white-haired man laughed and said proudly, "This is not a spiritual vein! This is the best spiritual vein!"

Yang Ziyun's eyes widened immediately, and she exclaimed, "Impossible! How can there be a top-grade spiritual vein now!"

The white-haired man smiled but did not speak.

Xu Chen sneered: "What's so incomprehensible about this? These two guys have lived long enough!"

The white-haired man laughed and asked, "How's it going?"

"That's right! The reaction is very fast, and it's decisive enough!" The green-haired man on the side nodded with a smile, and his vague face recovered a little at this moment.

"How is this possible? How can a person live so long?"

Yang Ziyun has read the classics of the cultivation realm, not to mention the current era, even if it was 10,000 years ago, the people who could live for 10,000 years were only old monsters above the merger period, but when the world changed greatly, the masters of this realm had already left.

The hand holding the gun was still steady, and in the face of Yang Ziyun's suspicion, Xu Chen replied lightly: "Have you heard me use the word 'people' to describe them?"

Yang Ziyun instantly understood, and then looked at the two "people" on the stone altar curiously.

The white-haired man smiled at Xu Chen and said, "I have to say, your words are very accurate!"

"Can you put down your weapon?" I think we can have a good talk!" said the green-haired man suddenly.

Xu Chen replied seriously: "This is my habit!"

"Enough caution!" the green-haired man bowed slightly, and then smiled: "Habit is a good habit, but it doesn't work, so it's not necessary, right?"

Xu Chen shook his head firmly and said: "Habits are always useless, but as long as they are useful once, they can save their lives, and I won't gamble with my life!"

The green-haired man smiled noncommittally, and then said, "We want to ask you for a favor!"

Xu Chen frowned slightly and replied, "Can I refuse?"

The green-haired man smiled and said unhappily: "I have seen a lot of young people like you, who are overconfident, and do not want to trust anyone except themselves, and always feel that there is nothing in the world that they can't do!"

"I'm not your junior, you don't have to educate me!" Xu Chen's eyes were still calm, without joy or sorrow.

Seeing this, the green-haired man was more satisfied: "It's okay, at least it's not light." ”

"I've brought you here for one thing!" the green-haired man didn't mean to continue inquiring, and said directly, "Help us take two things out!"

As he spoke, the two people on the stone altar pinched each other, and two stone pillars immediately rose on the ground in front of the stone altar, and above each of them were placed two eggs the size of a grinding plate, one green and one white.

"Of course, I won't let you run in vain!" said the green-haired man as he pointed towards the stone wall, and a burst of light changed on the stone wall, followed by a brocade bag.

The green-haired man then pointed towards the brocade bag, and there was a loud noise, and the ground was full of spirit stones.

"I don't know if you came in for any other purpose, but that should be enough!"

"It's only a thousand yuan?" Yang Ziyun quickly glanced at it and frowned.

The white-haired man was annoyed and reprimanded: "Female baby, see it clearly, these are all high-grade spirit stones!"

Yang Ziyun was shocked when she heard this, and hurriedly lowered her head to look at it carefully, and found that the pile of spirit stones on the ground was indeed crystal clear than the medium-grade spirit stones, and the size was also one size smaller, exactly the same as the few pieces that she was lucky enough to see in Gaoqiu!

Immediately, Yang Ziyun turned her gaze to Xu Chen, and seeing that Xu Chen was still unmoved, she said again: "Why do the two seniors want us to do it? This little thing is not difficult for the two seniors, right?"

The two of them shook their heads with a wry smile and said, "We can't leave this formation, and we can't even stand up!"

When Yang Ziyun heard this, the two of them had turned their coiled legs into stones, which were connected to the stone altar below!
