Although most of the pills have passed their expiration date, Xia Fei and the others still searched very carefully—maybe some of them have a relatively long shelf life, and they can survive from tens of thousands of years ago to the present?

However, the reality is often harsh!

More than a dozen rows of cabinets were searched, but they didn't find a single bottle of pill that could still be used.

Zhao Poison Hand, Qian Poison Miasma and Li Poison Lie sat down on the ground in despair, and sighed: "Sure enough, it was in vain!"

Xia Fei didn't give up! For him, these pills that would be casually displayed on the cabinet were definitely not rare varieties, and they were probably the pills consumed on weekdays.

And the elixir that can really enhance potential, be reborn, and improve the realm can never be placed on the medicine cabinet casually.

There should also be a secret compartment or mechanism like a safe.

So, he said to Zhao Poison's hand: "Put some small poisonous insects out, and let them find out if there are secret passages, dark rooms, secret grids and the like in this medicine hall......"

Hearing this, Zhao's eyes lit up, and he immediately released a group of winged poisonous ants from their magic weapons, and then urged these poisonous ants to drill around.

Unexpectedly, they were really found. A few poisonous ants soon spotted a hidden compartment in a corner under the cabinet.

Qian Poison Miasma happily opened the dark grid and took a look, and his face turned black again in an instant!

"Damn!

It turned out that what was stored in the secret compartment was not the pill, but the jade pill recipe with the names of various pills, as well as the ingredients of the pills and the method of refining.

For their brothers, this thing is almost like chicken ribs, unless it is taken to the auction market to auction after going out, it is of no use at all, and if it is auctioned, it may not be sold, after all, it is a Danfang tens of thousands of years ago, after these tens of thousands of years of improvement, these ancient recipes may not be able to be refined by alchemists - not to mention anything else, just after these tens of thousands of years, I don't know how many kinds of spirit grass have been extinct!

However, Xia Fei was very interested in these things, when he was in the Nether Realm, he had refined the "Nine Turns Fire Kwai Pill", and now that he has obtained these pills, he can just study them, and maybe he can use them when refining the pill in the future.

So he was given the key space.

At this moment, suddenly a strange fragrance emanated from some corner. Everyone's attention was immediately captivated.

Suddenly, a few small poisonous ants flew over, leading Xia Fei and Zhao Poison to a rough and damp stone wall, on which traces of the mural could be faintly seen, but after tens of thousands of years, the mural also weathered and fell off a lot, and it looked a little mottled, coupled with the moss cover, it was almost impossible to see what the previous mural depicted!

If it weren't for the little ants that brought them in, most of them wouldn't have noticed.

The strange smell that everyone smelled just now emanated from this stone wall!

Xia Fei noticed that there was a place where the moss was peeling off on the stone wall, and it seemed to be a palm-sized place that had sunken down. He pressed it, and he heard a sound of the machine turning, crunching, very penetrating.

Soon a long and narrow corridor appeared in the stone wall, and the strange fragrance came surging, filling the entire medicine hall.

"I really found it!" Zhao Poison Hand, they couldn't believe that this was true, they could emit such a strong fragrance, and the elixir in it was definitely extraordinary.

Everyone rushed in, along the narrow road, and finally came to a place that made everyone jaw-dropping—this was not a place where cherished elixirs were stored, but a medicinal field planted with all kinds of exotic flowers and plants.

It really responds to the old saying: how great is hope, how great is disappointment!

I thought it was a mountain and a river with no way out, and the willows and flowers were bright and another village, but I didn't expect it to be another village!

Looking at the twitching expressions on everyone's faces, Xia Fei became happy, he took out the jade pill just now, and looked at it silently, sure enough, most of the medicinal materials on this pill can be found in the medicine field.

And the most commendable thing is that these medicinal materials are all old medicinal materials that are more than 10,000 years old, such as 10,000-year-old immortal mushroom, 10,000-year-old jade fruit, 10,000-year-old purple ginseng, 10,000-year-old herb, and 10,000-year-old ice flower......

Any one of them can be sold for a sky-high price!

Therefore, Xia Fei couldn't help laughing, and immediately summoned the thirteen salted fish Taibao, and was about to ask them to help harvest the medicinal materials together, but the golden-maned male lion said: "This can't be done! If these medicinal materials are pulled out and piled together like this, it is easy to lose their medicinal power, and there will be a mixture of medicinal power between different medicinal materials, and then a pile of 10,000-year-old elixir will become a pair of waste firewood, which can only be dried and burned on fire......"

Being reminded by it like this, Xia Fei patted his head and knew that he was too anxious!

So he hurriedly returned to the medicine hall to find jade bottles, jade boxes, jade altars and other jade objects, and the elixir of ten thousand years was stored in a jade container in order to effectively preserve the medicinal properties.

After finding all the containers, he pulled out the various 10,000-year-old elixirs one by one and stored them in the key space.

Seeing that they couldn't help much, Zhao Poison and the three brothers simply returned to the medicine hall, released the poisonous insects, and then refined the Hundred Poison Pill.

Spiders, centipedes, poisonous snakes, toads, poisonous ants...... Soon the entire medicine hall was occupied.

Qian Poison Miasma thought about it, and threw out a crimson pill from the storage bag, and with a "boom", it exploded into red powder in mid-air and sprinkled all corners of the medicine hall.

After those snakes, insects, rats and ants were contaminated with the red powder, they immediately went berserk and desperately tore at other poisonous insects that could be seen in front of them......

The toxins in the bodies of the bitten poisonous insects flowed out quickly, converging towards the most central position of the medicine hall.

About half an hour later, the medicine hall was full of broken poisonous insect corpses, and the center of the medicine hall gathered and condensed into a colorful poison ball, the size of a basin, floating in the air, and the poison ball gathered all kinds of toxins.

Eventually, beneath this ball of poison, only nine of the most powerful poisonous insects remained.

The poisonous insects no longer bit each other, they occupied different positions, staring at the poisonous ball in mid-air.

At this time, Zhao Poison Hand, Qian Poison Miasma and Li Poison Lie glanced at each other, slammed their chests, and spurted out a mouthful of blood.

This mouthful of blood contained most of the life essence in their bodies, and all of it was sprayed on the poison ball in midair.

The originally colorful poison ball instantly swelled and turned blood-red, and the venom inside seemed to be soaked and turned red.

At the same time, with Li Poison's roar, the last nine poisonous insects occupying different directions burst open in an instant, and the essence of life and venom all converged on the poison ball that was soaked in red.

"Click!"

The poison ball began to collapse from the outside in, as if it had been compressed by a huge and incomparable force, and its body was pressed smaller and smaller—in the end, only a fist-sized crystal remained, faintly blooming outward, and after a dozen breaths, the light was completely restrained, and its appearance became unpretentious.

At this time, although Zhao Poison looked very weak, he smiled with great satisfaction: "Hundred Poison Pill, I have finally practiced!" (To be continued.) )
