Zhang Heng turned around and saw Dugu Sheng holding a strange hat in his hand.

Yes, it should be a hat, but its shape is not flattering, like an upside-down watermelon rind.

Since it is a watermelon rind, the color is naturally green.

"I caught such a thing?" Dugu Sheng was a little devastated, he was also similar to Zhang Heng, he had a lot of choices, but in the end, he chose this thing according to the inspiration in his heart.

When I scooped it up, it turned out to be a green hat, which made his angry nose smoke.

What a great opportunity this is, how many treasures did he pass by, and finally chose such a thing, how could Dugu Sheng not be angry?

"Green hat, green hat!" Dugu Sheng gritted his teeth, almost throwing this thing back.

But in the end, he was still a little reluctant, after all, this was the treasure he finally chosen.

But his mood is really not beautiful.

"Let me see. Zhang Heng took the "watermelon skin", and his mind was swept away, but his face was moved.

"Idiot, you've got a big bargain!"

"What's that?" Dugusheng opened his mouth wide.

"The material of this thing is a blue sky stone ......" Zhang Heng took a deep breath, and his eyes showed a little essence.

In his opinion, the opportunity that Dugusheng got was far better than him.

"What is the Blue Sky Stone?" Dugu Sheng shook his head, he hadn't heard of it at all.

"The Blue Sky Stone is an extremely rare genius earth treasure, growing at the edge of each star, its conditions are extremely harsh, tens of thousands of years to breed, maybe a fist-sized piece, and the Blue Sky Stone you get, like the size of a human head, is simply rare in the world...... Moreover, the person who got this thing was obviously knowledgeable, and he hollowed out the middle of the blue sky stone and turned it into a hat, making it a priceless treasure!" Zhang Heng said.

"Priceless treasure, that's it?" Dugu Sheng looked like you don't fool me, he said in disbelief: "What's the value of this thing?"

"The Blue Sky Stone cannot be used for refining. Zhang Heng shook his head.

"His role is to practice special laws!"

"Law?" Dugusheng grasped the point.

Zhang Heng is talking about the law, not the law.

"The law is just a manifestation of the law, and the law is something that only immortals can master, the Qingkong stone itself is not tough, nor does it have any refining value, but it itself is accompanied by the power of time, anyone who practices the law of time, wearing this thing, will progress rapidly, it is possible to master the law of time in advance!" Zhang Heng looked at Dugu Sheng, threw the watermelon skin back to him, and said, "Didn't you get a magical power for an instant?" According to the convention, that time supernatural power, if you want to succeed in cultivation, there is no time for you, but with the assistance of the Blue Sky Stone, you can make a lot of money in a day, and you will make a lot of money!"

Dugu Sheng was a little dry by Zhang Heng's words, he stared at the "watermelon skin", his eyes blinked, maybe he finally believed that this thing was a treasure, his eyes were a little bright, after all, no matter how he didn't pay attention, he also knew what the law of time represented, this is one of the strongest laws.

"But why is it green......" Dugusheng wailed depressedly.

Just thinking about it, when he was cultivating by himself or fighting with others, he felt a little collapsed with a green hat.

The man wears a cuckold on his head, and even a thick-skinned guy like him is a little hesitant.

"Because the color of the blue sky stone itself is green, you don't want to use dyes or anything to change its own color, because this will destroy the original material of the blue sky stone...... Zhang Heng comforted: "You should think about it, when you have great powers, what kind of scenery it will be?

In his previous life, such a large piece of blue sky stone, even Zhang Heng, who was an immortal venerable, would have a trace of wanting to collect it.

One can imagine how valuable it is.

When Dugu Sheng heard this, he also figured it out, gritted his teeth and said.

"Green is green, if you want to live a decent life, you have to bring some green on your head!"

He put the watermelon peel on the door of his head and said in surprise.

"I really seem to feel a mysterious aura, is that the power of time?"

Zhang Heng nodded and put the Qingsuo Sword into the dantian.

This sword is a magic weapon for him, and when he uses Vientiane Gong to restore the spirit of the weapon in the future, it will be a magic weapon of the complete body, and it will become one of his powerful hole cards.

"Is there still a fourth layer? The goddess asked us to find the Golden Pill of the Crossing Tribulation, where are we going to find it?" Dugu Sheng asked.

Zhang Heng also frowned slightly, this third layer, there is no obvious ladder.

"This fourth layer should be the true essence of the secret vault, there may not be many things in it, but they are all treasures of the same grade as the Golden Pill of the Crossing Tribulation, so there must be a special law before you can enter the fourth layer. ”

Dugu Sheng was stunned and said.

"Aren't we blind, then?"

Zhang Heng shook his head and said.

"Not necessarily. ”

With a wave of his hand, hundreds of storage rings flew out of the sky.

These storage rings are all Penglai disciples and elders that he killed all the way before.

Before he had time to take a closer look, he swept away these storage rings in his spare time, which was a trophy and a windfall.

There are many people who do this like him, and the guys of Boss Wu also do the same, they have been working as coolies for a long time, and they are going to be poor and crazy, but now they are making a lot of money.

"There should be Penglai's practice in this. ”

Zhang Heng's divine thoughts were divided into wisps and entered these storage rings.

He searched for the jade slips in the ring, found thousands of exercises, eliminated the big road goods, useless things, and finally, found thirty-seven Penglai exercises.

Dugu Sheng looked at the thirty-seven exercises floating in front of him, and said at a loss.

"Do you want to practice all these exercises?"

No one can be sure which exercise can trigger the fourth layer of prohibition, and perhaps none of these thirty-seven exercises are suitable.

"That's exactly what it means. Zhang Heng closed his eyes.

He had already begun to practice the exercises of the first jade slip seed.

"I'll go, you're not crazy, are you? You just practice here, how long will it take?" Dugu Sheng felt that Zhang Heng was completely useless in doing this, a practice, only to understand that the time required to integrate and then achieve success in cultivation would take a year and a half, to say the least.

And here, there are thirty-seven exercises, no matter how Zhang Heng defies the sky, he has to practice for more than ten years, right?

But no matter what he said, Zhang Heng had already begun to practice.

That is, after dozens of breathing exercises, Zhang Heng opened his eyes.

"Not true. ”

He tossed the jade slip aside and looked at the second.

"You've cultivated?"

Dugu Sheng was shocked and hurriedly picked up the first jade slip.

This exercise is called "Purple Qi Comes from the East", and when the cultivation is completed, there is purple intent flashing in the eyes.

And now, there is a faint purple light in Zhang Heng's eyes, which is a sign of Dacheng.

Dugu Sheng was completely stunned, and it took a long time before he spewed out a dirty word.

"Grass!"

He almost forgot that Zhang Heng was not an ordinary person at all, this guy was a freak and a demon.

In fact, these exercises may indeed be Penglai's secret, but for Zhang Heng, the grade is obviously a little insufficient.

These things that are not even immortal skills, what is the difficulty?

Dignified Eternal Immortal Venerable, what haven't you ever seen? This kind of exercise, you can already understand it at a glance, does it take any effort?

In less than a quarter of an hour, Zhang Heng had already cultivated almost ten exercises.

Dugu Sheng on the side is already numb.

Just when Zhang Heng was practicing to the twenty-third exercise, his eyes suddenly released a fine light and said.

"That's it...... Little Ruyi Heart Sutra!"

Zhang Heng pinched the seal with both hands, and a blue and purple jade Ruyi slowly floated out in the clouds.

This is the natal jade Ruyi condensed by the small Ruyi Heart Sutra, which has the power of a flying sword, which is quite powerful.

At the moment when this jade Ruyi appeared, the third layer of this secret vault suddenly shook, and a vast power enveloped Zhang Heng and directly brought him to a new world.

By the time he opened his eyes, he was already in an antique pavilion.

There are shelves everywhere, and on the shelves, there are treasures on display.

And facing Zhang Heng is the Tribulation Jindan!
