After obtaining the Twelve-Rank Lotus Great Array, Yan Yu and the three of them followed the route on the map and headed towards the next vague location.

After walking through the winding road, another stone gate blocked their way.

"Let me do this!" Master Cao rolled up his sleeves and prepared to perform.

I saw that he unlocked the seal of his left hand, tied up his horse steps, and sank into the dantian, and then shouted loudly, and slammed his force!

Burst......

The cute little face of the evil king couldn't help but roll his eyes, covered his nose and said, "Lao Cao, are you a 10,000-year-old fart, why is it so stinky?" When the Buddha comes, he can burp you with a fart! ”

"Ahem, I held it for several days when I was locked in the bottle, and I didn't dare to release it because I wanted to, for fear of stinking myself to death," Master Cao said embarrassedly, "Strange, why can't I open this door?" ”

When Yan Yu pushed open the stone door of the Twelve Rank Lotus Array just now, he didn't use much strength, it was just an ordinary stone door.

Yan Yu looked at it with the eye of heaven and said, "There are still many prohibitions in the will, and there are also the same prohibitions on the door I pushed open just now, but it is just that it has become invalid because of its age. ”

"And this door?"

"Although there is a ban on this door, it is already fragile."

Yan Yu stepped forward and put his hands on the stone gate, with the help of Tianyan, he could easily find the place where the prohibition was weak, and inject a little true yuan, and the prohibition would instantly become invalid.

"That's it." Yan Yu said.

Master Cao tried again, and sure enough, he easily pushed open the stone door.

Behind this stone door, there were many more things stored.

The first thing that catches your eye is a huge bronze tripod.

This bronze tripod is three meters high, it needs to be surrounded by four people, it is not as boxy as Simu Wuding, but it is round and smooth, nine directions, carved with nine flying dragons, each dragon's mouth, there is a crystal clear dragon ball.

"The shape is a bit like the ground motion instrument invented by Zhang Heng?" Yan Yu observed it for a while, and then denied it, "The history of the fourth-layer site can be traced back to three or four thousand years ago, and Zhang Heng was a figure more than two thousand years ago...... This is certainly not a geomometer. ”

"Nonsense, didn't you see the word 'medicine' written on the ding? This thing is an alchemy furnace! The Evil King said disdainfully.

Yan Yu coughed dryly twice, and said unconvinced: "What kind of medicine is this?" How can I recognize the ancient Shu script? ”

Although he was not convinced, Yan Yu was convinced of the evil king, this guy had a mysterious background, not only knew a lot of things in ancient times, but also knew a lot about immortals, and even knew the ancient Shu script.

Yan Yu originally thought that the Evil King should be a strong man in the underworld, but now it seems that this guy is probably from another era.

The evil king walked around the alchemy furnace and deduced, "This thing should be the legendary Nine Dragons Xuanyang Ding!" ”

"How do you even know the name?" Master Cao wondered.

The evil king smiled: "I was just guessing before, but now this king dares to be sure that in this fourth-layer ruins, all the things buried in the ancient Shu sect are the ancient Shu sect, the previous heart-haunting seven love mirrors, the twelve-grade lotus array, and the Nine Dragons Xuanyang Ding in front of him, all of which are the treasures of the ancient Shu sect!" ”

"Evil King, do you know a lot about the Ancient Shu Sect?" Yan Yu asked.

"It's an understanding," the evil king said indifferently, "After all, this king can be regarded as having some unusual relationship with the Gu Shu sect...... It's a pity that thousands of years have passed, even if the era is prosperous, there is a possibility of decline, not to mention the sect of the ancient Shu sect. ”

From the tone of the evil king, Yan Yu seemed to be able to imagine how beautiful the Ancient Shu Sect was back then, but now, the Ancient Shu Sect was just a dusty ruin.

"Boy, if you have the opportunity in the future, this king will teach you alchemy!" The Evil King's Way.

"You still know how to do alchemy?" Yan Yu raised his eyebrows and asked, "How do you collect it?" ”

"Nonsense, blood!"

Yan Yu stepped forward, forced out a drop of blood from his fingers, and dripped it on the Nine Dragons Xuanyang Ding, and the Nine Dragons Xuanyang Ding really reacted.

The huge alchemy furnace floated up in the air, and after spinning in mid-air for a few weeks, it turned into a stream of light and rushed into Yan Yu's body.

"That's it?" Yan Yu hurriedly checked his body and sensed that the Nine Dragons Xuanyang Ding had indeed been taken into his body.

"The Nine Dragons Xuanyang Ding can be easily subdued by you, I think there is no successor to the Ancient Shu Sect," the evil king sighed, "In this ruins, I'm afraid there are still many treasures, fortunately, we came in time, otherwise we will be able to get it by the Guigu Sect, and I am afraid that no one will be able to stop your mother's footsteps in the future." ”

Not to mention the power of this Nine Dragons Xuanyang Ding, just the twelve-rank lotus array is very awesome.

"There's a lot of stuff around here." Master Cao walked around curiously, looking around.

Yan Yu touched his chin and analyzed: "The Nine Dragons Xuanyang Ding is here, this may be the alchemy room of the Ancient Shu Sect in the past, and the shelves next to it are all alchemy medicinal materials from thousands of years ago?!" ”

Most of the medicinal materials that can be used for alchemy are not ordinary medicinal materials, but they have not experienced thousands of years of devastation, and when Yan Yu and the others pushed open the stone gate, most of the medicinal materials had already turned into flying ashes.

A small number of the remaining medicinal herbs also decayed at a rate visible to the naked eye.

"I'm afraid there's nothing left left."

When Master Cao regretted it, he suddenly caught a glimpse of a bamboo slip in the corner beside him.

Maybe there is something in the bamboo slips?

Master Cao didn't say a word, and grabbed the bamboo slip, but as soon as his fingers touched the bamboo slip, he felt a thunderous pain, and then he was dizzy, his body was numb, and he fell straight to the ground.

"Lao Cao?!"

Yan Yu's face changed, and he hurriedly stepped forward to support him: "Are you okay?" ”

Master Cao twitched a few times, and the white of his eyes finally recovered, he covered his head and said, "Master, I'm ...... I was electrocuted? ”

"It looks like it." Yan Yu said.

Master Cao hurriedly let go of the bamboo slip in his hand: "This, how can this thing have electricity?" ”

Yan Yu picked up the bamboo slip in confusion, but it was not shocked, and after unfolding it, there was no text engraved in it.

The evil king smiled: "Lao Cao, this bamboo slip is not ordinary, think about it seriously, is there something more in your mind?" ”

Master Cao was stunned for a moment, and then said in a daze: "It seems to be ...... It seems like something more, let me brush it again......"

The Evil King picked up a rotting herb on the ground and asked, "What is this?" ”

"Chill grass?" Master Cao blurted out.

"Lao Cao, do you recognize the medicinal materials of the ancient period?" Yan Yu was surprised.

Master Cao frowned, and suddenly a flash of inspiration: "it...... It's a bamboo slip...... The bamboo slips stuffed this knowledge into my head, and I was able to not only identify herbs, but also know how to grow, cultivate, and even ...... Know how to make alchemy! ”
