Slowly twisting the lock cylinder, a crisp sound of "click" sounded continuously, as if there were several rusty pinions turning and rubbing, and Li Hao shuddered when he heard it.

The sound was undoubtedly indicative of one thing—the small copper lock contained a number of small but delicate mechanisms, if anyone really tried to break it violently...... God knows what will happen!

Anyone who underestimates the ancient Chinese tricks will end up paying a terrible price for their ignorance!

The key was finally opened, only to hear a crisp "click", and the lock on the box was finally opened.

Taking a deep breath, Lin Hao carefully opened the lid of the box, and the nerves in his whole body were tense to the extreme, for fear that some hidden arrows would suddenly shoot out of the box, and Lin Youquan on the side also quietly moved a few steps to the side, for fear that he would suffer from the pond fish.

In a decadent groan of "squeak, squeak", the lid of the entire box was finally lifted completely, and in the end, there was no hidden arrow or anything like that.

Li Hao breathed a long sigh of relief, and quickly set his eyes on the inside of the box, and when he saw him, he was stunned on the spot, and the whole person was stupid.

Lying in this mysterious box, there is only one jade pendant!

The size of a one-dollar coin, embossed with a vivid pattern of yin and yang fish, the jade is white and flawless, as if it was made of cream condensation, and from the perspective of jade alone, this is definitely a priceless piece of jade, however...... Why is it a piece of jade?

After being stunned for a long time, Li Hao suddenly picked up the box and began to rummage carefully, knocking and touching it, wanting to see if there was any hidden mezzanine in this box, and what other treasures were hidden in it.

However, after rummaging for a long time, he was stunned and didn't find any other mezzanine dark grids, and there was indeed only this jade pendant in the whole box!

Li Hao finally looked at Zhang Zhongxiao again, "Are you sure...... No one else has opened this box before me?"

As soon as he heard this, Zhang Zhongxiao's face immediately sank, "Master Li, what do you mean by this? You don't suspect me of being a prisoner and stealing, right? I'm already a person who is half buried in the soil, why are I still greedy for these things outside my body? I dare to swear to the sky with the lives of the whole family, absolutely no one has ever opened this box!"

"I didn't mean that...... Alas, forget it, just let me fart. Li Hao sighed a little depressedly, "This is strange, how can it be a piece of jade?"

Lin Youquan, who was on the side, couldn't help but come up and ask, "Senior brother, why can't it be a piece of jade?"

Li Hao shook his head and said: "Do you remember, I told you last time, our family has not grown an inch of grass for twenty years, and even my parents have not aged and declined, nine times out of ten, the things in this box are making trouble, and Zhang Lao's current physical condition also proves my previous conjecture, the treasure in this box will devour the surrounding aura essence, which will lead to the decay and aging of nearby lives...... Is this a piece of jade pendant that can do it?"

"Also, the night I first found the box, I noticed that it often quivered, as if something was struggling inside. Li Hao frowned and said, "I always suspected that there was some strange living creature hidden inside, otherwise it would not have trembled with the box, but now it is only a jade pendant inside...... Could it be that Yu Pei will tremble by herself?"

Lin Youquan was also dumbfounded by rhetorical questioning, indeed, the jade pendant is dressed like a god in Huaxia, what kind of metaphysics such as nourishing qi and cultivating people is grabbed, but I have never heard of any jade that can directly absorb the essence of life, let alone any jade that will tremble on its own.

If there is, it's also in horror and movies!

This is indeed a bit unreasonable, if it weren't for the 100% trust in Zhang Zhongxiao, a friend of life and death, even he would be a little suspicious that Old Man Zhang was secretly dropping the baby!

After being silent for a long time, Li Hao closed the box and said: "Forget it, let me observe it for two days to know, no matter what, I still have to thank Zhang Lao, if it weren't for you, maybe I wouldn't be able to open this box for the rest of my life." ”

Zhang Zhongxiao smiled a little reluctantly, "Thank you, you don't have to, as long as Master Li doesn't suspect me of stealing from me." ”

Li Hao's face turned red, turned around and grabbed the pen on the desk, brushed and wrote down a prescription, "Lao Lin, let someone go and grab the medicine tomorrow and bring it back to me, don't forget." ”

Lin Youquan took the prescription and glanced at it, frowned and asked, "What is this...... A prescription for Lao Zhang?"

"You can also use it to strengthen the foundation and cultivate energy. Li Hao smiled: "As long as you take this regularly and quantitatively, it is conservatively estimated that you can live for at least ten more years." ”

"Ten...... Ten years?!"

Lin Youquan and Zhang Zhongxiao screamed in unison, so shocked that they couldn't roll their eyes.

What kind of medicine is this, which can prolong people's life for ten years?

I'm afraid that the legendary elixir is nothing more than that, right?!

Zhang Zhongxiao was so excited that he almost didn't kneel down and kowtow to Li Hao, let alone ten years, he was already satisfied even if he could live for another half a year, how did he know that Li Hao would take out such a miracle medicine?

This trip to Yanjing is worth it!

When he came out of the study, it was almost dawn, and Li Hao didn't bother to rush back to the Su family's villa, so Lin Youquan directly arranged a room for him to live in.

As soon as he entered the room, Li Hao immediately took out the strange jade pendant again, looked at it carefully, trying to see any secrets from it, but no matter how he looked at it, he had no clue, it was clearly just an ordinary jade pendant, and he couldn't see anything strange at all except for his extraordinary appearance!

"What the hell, how could it be such a thing?" Li Hao scratched his head the more he looked at it, he was originally looking forward to what earth-shattering peerless treasure it would be, and even imagined that it would be a treasure left by his predecessors in cultivation, but it turned out to be just such a ......

Thinking of this, Li Hao's head suddenly flashed, "Wait a minute, the treasure left by the cultivator......? Cultivator...... Artifact?!"

When he looked down at the jade pendant in his hand again, Li Hao's eyes suddenly lit up!

The jade pendant itself is not mysterious, except for those so-called metaphysics such as qi nourishment and self-cultivation, the rest are basically used as decorative items, but jade has an extremely important meaning in the world of cultivation - jade is the most common material for cultivators to make magic weapons!

If this jade pendant in his hand is really a magic weapon left by his predecessors in Xiuzhen...... Then everything can be explained—why can it absorb the aura of heaven and earth, the essence of the sun and the moon, causing the surrounding plants and trees to not grow, why can it vibrate inexplicably as a dead thing?

Because it's a magic weapon!

It is a treasure created by cultivators!

"There must be a secret in this jade pendant. The more Li Hao thought about it, the more determined he became, "The jade pendant that can make the cultivation mad demon Emperor Jiajing regard it as a treasure will definitely not be an ordinary product, there must be some secret hidden in this jade pendant, but I haven't discovered it yet!"

Gritting his teeth, he began to observe carefully again, he saw every corner and every detail of the entire jade pendant carefully and clearly, and only hated that there was no microscope or anything like that around him that could be used to assist in observation.

But after looking at it for a long time, he still found nothing, so angry that he scratched his head, "Damn, what secrets are hidden in this jade pendant? Why can't you see any signs of abnormality?!"

And just when he was so angry that he was about to go crazy, the unexpected joy came unexpectedly - when he inadvertently aimed the jade pendant at the bright moon outside the window, the whole jade pendant suddenly changed!

It's like diesel meets an open flame, and this jade pendant shines instantly as soon as it is stained with moonlight!

The white and greasy jade instantly seems to have turned into an incandescent lamp, transmitting a dazzling white light, and the surface of the jade pendant also faintly flows with a layer of brilliant fluorescence, which sets off the entire jade pendant like a piece of crystal, which is beautiful and amazing!

Enduring the dazzling white light, Li Hao was taken aback on the spot when he tried his best to look towards the center of the jade pendant!

In the middle of the yin and yang fish pattern, a precise pattern slowly emerged, and the lines were so dense that it was dazzling and couldn't see clearly, but the next moment, the bright moonlight turned into a projector, directly mapping the entire pattern to the floor!
