"You can go for revenge, I'll go down and see what treasures there are?" Tang Yin nodded, he couldn't come back empty-handed in the middle of the night.

If it is really as Zheng Haifeng said, under the sinkhole is the ruins of a sect, or the treasure place where the sect once hid, there may be a big harvest.

"Okay!" Zheng Haifeng nodded.

Flew directly into the sky, and then volleyed to the sky above the sinkhole, he could have passed through it extremely quickly, even if the people around the sinkhole found it, they didn't have time to stop it.

But he landed slowly, so that everyone could see clearly.

"You, how can you fly?" Some of the people around the sinkhole knew Zheng Haifeng, and some of them were brought by Zheng Haifeng's betrayed companions.

Seeing Zheng Haifeng falling slowly and levitating above the sinkhole, their minds couldn't turn around.

People in the supernatural realm, as long as they have a little common sense, know that flying is the exclusive domain of grandmaster-level powerhouses, and it is also one of the most significant signs.

If you don't reach the grandmaster level, no matter how good your body is, you can only make the time in the air longer, and it is impossible to fly at all, unless you use something outside your body.

And now Zheng Haifeng is dressed in tattered clothes, and he doesn't even have a weapon in addition, he is now suspended in the air, and it is easy to judge that he is relying on his own ability.

"Why do you think I can fly?" Zheng Haifeng smiled.

Before going down the sinkhole, he was very weak.

In the face of the alliance of the major forces, he didn't even dare to say anything to refute, otherwise he wouldn't even have a chance to go down the sinkhole.

Now, at last, his chance to get revenge has come.

"It seems that it has been suppressed for too long, and I need to vent it!" Tang Yin has been secretly seeing Zheng Haifeng's performance and smiling.

Zheng Haifeng is so swaggering, he should have suffered too much anger before, but now that he has the ability, of course he has to take a breath of evil anger in his heart.

"You are limited to leave within three minutes, otherwise don't blame me for being rude!" Zheng Haifeng said as he waved his hand.

Rumble!

A palm technique that falls from the sky.

On the ground not far from the sinkhole, a slap mark larger than a person appeared, sinking deep into the hard ground.

Of course, it's not a divine palm, it's just a use of energy.

Stepping into the grandmaster level, as the realm improves, the supernatural powerhouse uses energy more freely, and it is not necessary to require specific skills.

Just like Zheng Haifeng's attack just now, it was just a casual attack with energy out of the body, and it was an ordinary attack with no amplification.

The person in charge of guarding the sinkhole saw the slap prints on the ground, which were bigger than people, and fell into the hard ground, smashing several stones into pieces.

If you shoot them, I'm afraid you won't even have time to scream, and you will be slapped into a meatloaf.

Walk!

If there is a coward, turn around and leave immediately.

The rest of them wanted to hold on for a while, but when they saw that some people had already started to leave, and then looked at the palm prints of the people on the ground, they all turned around and left.

In the blink of an eye, there was no one around the sinkhole.

"Why didn't you kill them?" Tang Yin also appeared.

"They didn't participate in attacking me, there's no need to kill them!" Zheng Haifeng shook his head, although he had a lot of anger in his heart, he didn't lose his mind.

The people around the sinkhole, even if they were hostile to him, did not participate in the attack on him, just run away.

Of course, if someone is disobedient, he will not be polite.

There was no one around the sinkhole, and of course no one was going to stop the two from going down, and the two soon came to the bottom of the sinkhole, entering the dark underground cavern.

"Are there traces of the formation?" In the process of descending to the bottom of the sinkhole, Tang Yin found some traces of the formation.

It's just that the age is too long, at least tens or hundreds of years, and many traces have been worn out by time, so it can only be judged that there are formations, but more things are no longer exquisite.

After discovering the formation, Tang Yin speculated that the sinkhole was not simple.

"Maybe it's not a naturally formed sinkhole......" Tang Yin quickly came to the conclusion that the sinkhole did not originate from nature.

This place is likely to have undergone geological changes dozens of hundreds of years ago, but there are artificially arranged formations deep underground.

Because of the change of geology, the structure of the formation is changed, which in turn causes the formation to explode and form a sinkhole.

After the explosion, most of the traces disappeared with the explosion, and only a few remnants of the formation traces were discovered by Tang Yin.

"If there is a big explosion in the formation, I'm afraid most of the things have been destroyed!" Tang Yin thought regretfully as he entered the underground cave.

From the remaining traces, the sugar can also be judged to be a large formation, and the destructive power of the explosion is not trivial.

"Zheng Haifeng, do you dare to come back to die?" When the two were walking all the way forward, a group of people suddenly came up to them.

"I didn't kill all of you traitors, I'm unwilling!" As soon as he saw the person taking the lead opposite, Zheng Haifeng's eyes were on fire.

Hearing Zheng Haifeng's words, Tang Yin knew who the person opposite was, it must be Zheng Haifeng's companion, who agreed to come on an expedition together, but betrayed Zheng Haifeng.

Speaking of which, Tang Yin wants to thank them, if they hadn't betrayed Zheng Haifeng, Zheng Haifeng would not have been in danger and dying, like Tang Yin begging for help.

It was they who gave Tang Yin a powerful general, but Tang Yin would not save them, and they had to pay the price for their betrayal.

"Kill, if you want to blame yourself, you have already killed just now, why do you want to come back?" The person who betrayed Zheng Haifeng had a hideous face, and he waved his hand and killed.

"You take revenge slowly! I'll go to the front to have a look first......" Seeing them coming up the mountain, Tang Yin smiled and turned into another fork in the hole.

The strength of the people who came up was not strong, and the highest one was only a nine-star, and it was not the opponent of the grandmaster-level Zheng Haifeng at all.

Yes!

As soon as Tang Yin turned into another cave, he heard a miserable scream, of course it was not Zheng Haifeng's, it was sent by his companion who had betrayed him when Zheng Haifeng took revenge.

Hey?

As he walked, Tang Yin suddenly found a group of people in front of him, crackling and fighting more fiercely, and on the other side of the crowd, there was a cave that was obviously artificially dug out.

The door to the cave has been opened, and it can be seen that there are many old shelves inside, and some of the things placed on the shelves.

Clearly, these people were fighting over the items inside.

"Stop, I want the contents inside, you can get out!" Tang Yin swaggered out, he was not afraid of revealing his identity.

When he came down from the sinkhole just now, he had already changed into another person, and it was impossible to find his true identity according to his current appearance.

After Tang Yin shouted, he came to everyone.

"Who are you?" asked Tang Yin, a man in his forties.

Get lost!

Tang Yin didn't answer him at all, and waved his hand like a fly, looking like he didn't use any force at all.

The man who questioned Tang Yin and stopped Tang Yin on his way was like being hit by a big truck, and the whole person flew out until he reached the stone wall more than ten meters away.

With a loud bang, the man was rigidly embedded into the stone wall, and the whole person seemed to be asleep without saying a word.

Everyone was shocked!

Because the man was a nine-star peak, he was almost at the grandmaster level in one step, but he was killed by Tang Yin lightly.

"Zong, Grandmaster?" someone said in a trembling voice.

"Even if you have a little knowledge, I want the things inside, do you have any opinions?" Tang Yin smiled and nodded, and then the whole person slowly floated up, jumped to a place more than one person high, and looked at the people in front of him in the air.

Everyone no longer doubted, because flying was the patent of a grandmaster-level powerhouse, and Tang Yin was suspended in front of them in the air, just to tell them that Tang Yin was a grandmaster.

Although there were thirty or forty of them, and all of them were relatively strong supernatural powerhouses, they were facing a grandmaster.

If they can attack Tang Yin at the same time, maybe Tang Yin will be injured by them, and maybe even killed.

The problem is that in actual battles, even if many people beat one person, in fact, only a limited number of people can attack Tang Yin at the same time.

And other people who were relatively behind, or those who were blocked by their companions, had no way to attack Tang Yin at all.

Run!

Realizing that he was facing a grandmaster-level powerhouse, and then looking at the man who didn't know his life and death embedded in the stone wall not far away, he turned around and ran away a little timidly.

They have no courage in the face of an invincible enemy.

In the blink of an eye, the person in front of him ran away.

Tang Yin came to Shimen step by step!

It was discovered that the stone door was not opened by these people, but was originally broken, and it was broken a long time ago.

When I entered, I found rows of shelves with different books, some made of special paper, some made of special animal skins, and even some jade slips.

Made of special paper, it has long been rotten.

Made of special hides, a small part of which is not corrupted.

The jade slip was relatively well preserved, but unfortunately there were only five pieces in total, which were put away by Tang Yin as soon as possible.

He even put away the entire shelf, including the damaged books.

He wanted to go back and try it and see if the corrupted books could be preserved before they turned to ashes.

Because of those corrupt books, the paper still maintains the state of the book because there is no external force, but it cannot be touched, and it will immediately turn into pieces when touched.

"This should be a library pavilion!" Tang Yin judged after emptying.

Eventually, he stepped out and went on to explore something else.

Soon he found another warehouse, which contained a lot of weapons, but Tang Yin came a little late, most of them had already been moved, and some of the remaining ones were of inferior quality or rotten, which were being picked and picked by the remaining people.

"Put it all down!" Tang Yin stepped in.

"Get out, whoever takes it is whoever!" A person who was holding two relatively intact weapons, as soon as he heard Tang Yin's words, he looked at Tang Yin's people again, and scolded him very unceremoniously.

Rumble!

The person who reprimanded Tang Yin couldn't even finish a sentence, so Tang Yin flicked his sleeves and sent him to the stone wall more than ten meters away.

"If anyone doesn't put down his weapon, he is a role model!" Tang Yin looked at the others, and his fierce momentum exuded.

"I don't know which family you belong to, but we had an agreement before we came down, and now this batch of weapons already belongs to us......" Seeing that Tang Yin was about to rob, a person with an obvious high status stood up and reprimanded.

Tang Yin understood, what he meant was that there were certain rules for the distribution of the spoils of several big forces in Tiankeng.

According to the rules, the weapons in front of them belong to them.

He didn't know Tang Yin, but he regarded Tang Yin as a member of a certain force and accused Tang Yin of violating the rules.

"Either let it go or die, you choose one, right?" Tang Yin smiled coldly, he was an outsider, why should he follow the rules?
