Merlin didn't rush to find the treasure, because he knew from Bai Li Tou Red that the biggest treasure of the Seven Star Palace was the secret room hidden deep underground.

Hidden in the secret room is a mysterious elixir that can quickly grow ordinary animals into terrifying monsters.

Hidden is the research results of Empress Wu Qing resurrecting the dead.

Hides the Hades Banner that can control zombies!

These secrets were too shocking for Merlin to be discovered by others, so he waited for everyone to disperse, and then walked around alone, and finally walked into a half-collapsed attic.

Searching for a treasure in a completely unfamiliar place is tantamount to looking for a needle in a haystack for those who don't know the way, but for Merlin, who has already explored the layout and route of the Seven Star Palace, it can be described as a familiar road, and there is no difficulty.

There was a secret passage in this attic, and according to the guidance of Bai Li and Hong, Merlin quickly found the entrance and walked in.

The Seven Star Palace is magnificent, the shortest hall is also seven or eight meters high, and the highest is two or three hundred meters, in this magnificent palace group, there is no difference between putting three or four hundred people in it and entering the realm of no one.

Mo Lin walked all the way along the secret passage, walked for about ten minutes, and suddenly opened up in front of him, and a large hall of tens of thousands of square meters appeared in his sight.

The main hall is resplendent with gold, the walls and the five dragon pillars that support the main hall are inlaid with gold and jade, and the turquoise blue light emitted by the ground shines all around, and at a glance, it is like a fairyland.

"It's a medium-grade soul stone!"

When he saw the blue stone under his feet, Mo Lin almost exclaimed, this tens of thousands of square meters of ground was actually paved with medium-grade soul stones!

In the middle of the main hall, there was a large pile of gold and silver ornaments, and according to the description of Bai Li and Hong, this was its original residence in the Seven Star Palace.

After approaching, Merlin found that the composition of these gold mountains was the same as the rockery in the cave, all of which looked dazzling but were actually worthless gold and silver jewelry.

This palace has gone deep into the ground, Merlin guessed that it was at least a kilometer or so from the ground, through the back door of the main hall, there was a wide and straight passage, when Merlin walked to the end of the passage, in front of him was a square twice as large as the main hall where Bai Li Transparent Red lived, and in the middle of the square, there were three inconspicuous stone houses sitting side by side.

"This should be the secret room that Bai Li Li Li Red is talking about. ”

The three stone houses are exactly the same, three meters high, no doors and no windows, about four meters in length and width, and ten meters apart, compared with the tall palace outside, it looks a little out of place, but Mo Lin has heard that the space inside is huge, and it is not as shabby as it seems from the outside.

Merlin opened the ring and took out a plate-sized black shard from it, drawing several runes in the middle of the four walls of the stone house on the far left.

This fragment was not a mortal thing, but a piece of dragon scales that was white and red.

As the runes were carved, the surroundings of the stone house suddenly lit up, and a radiant circle appeared on the ground in front of them.

Merlin stood on top of the magic circle, put the dragon scales in his hand in the middle of the circle of light, his hand just left the dragon scales, the magic circle under his feet suddenly emitted a bright white light, when the line of sight returned to normal, he was already standing in a room with dozens of shelves large and small.

At this point, Merlin's heart finally became excited, according to what Bai Li said through the red, Lei Huo's second evolution occurred only after stealing the pill here.

The space of the secret room is huge, and many of the shelves inside have fallen to the ground, colorful medicine bottles are rolling all over the ground, and there are patches of dark red blood spots on the smooth ground, which should be left when the white and red were gnawed.

Merlin carefully examined the vials on the shelf.

The vials were of various sizes, some contained granular pills, some contained finely crushed powders, and some contained unknown solutions.

The label on the side of the bottle details the names of these pills, the herbs needed to refine them, and the provenance.

Most of the names of the herbs Mo Lin had never even heard of, but the few elixirs he had seen in the books were all priceless treasures, and any one of them could be sold at auction for hundreds of thousands or even millions, and those who had not heard of it must not be cheap.

Of course, these mentioned herbs were all refined into pills, and to Merlin's dismay, he looked at three shelves in a row, but he couldn't find any explanation of the use of the pills.

There was no explanation of the efficacy of the pills, although he knew that these pills were precious and Mo Lin did not dare to take them rashly, just when he was struggling with whether to find a smaller pill to try, a blue-red medicine bottle came into his sight.

"Top-grade Wuji Dan?"

Seeing the name on the medicine bottle, the corners of Merlin's mouth twitched violently, and his eyes widened suddenly.

Wuji Dan Merlin has heard of it.

It was seen in a book about "Detailed Notes on Elixirs" brought out by the underground palace.

Later, Wang Ba also mentioned it to Merlin a few times.

The source that led to this topic was that Merlin felt that the cultivation of the barbarian warriors of the Sword God Legion was too slow, and he fantasized that one day he could let Xiaobao refine a magic medicine that could instantly increase his cultivation level, and at that time Wang Ba mentioned Wuji Dan.

"Wuji Dan, a fifth-level elixir, is only a line away from the holy medicine, and after taking it, you can instantly condense the soul ring and improve the level of the martial artist. ”

This is the explanation of Wu Ji Dan in the book.

It's just that, compared to the Chongmai Pill, the value of the Martial Pole Pill cannot be measured by soul stones at all, looking at the entire Black Dragon Empire, there are only three alchemists who can refine the Martial Pole Pill, and the annual output is only thirty pills.

These Martial Pole Pills will not flow into the auction at all, and they have been booked by the major wealthy nobles long before they are refined.

Especially the old pharmacist in the Medicine King Hall who could refine the mid-grade Wuji Pill, it is said that the pills that he would refine in the next twenty years have all been booked, and all the medicine money has been sent to the Medicine King Palace.

Huge profits!

Idols.

At that time, when he heard this, Mo Lin's envious saliva was about to flow out, and he secretly decided that sooner or later, one day he would go to the Medicine King Hall to see what this old pharmacist looked like, if he could let him point out Xiaobao and cultivate a senior pharmacist who could refine Wuji Dan, would he still need to work hard to make money from mining in the future?

Wuji Dan also has good and bad quality.

According to what Wang Ba said, the probability of improving the level of the low-grade Wuji Dan after taking it is about 40%, and the success rate of the middle-grade Wuji Dan is about 70%, as for the high-grade Wuji Dan that can increase the chance of promotion 100% and will not have any sequelae if you take it all the time, looking at the entire Black Dragon Empire, there is only one pharmacist who can be refined for thousands of years, and he is the first emperor of the Tianchi family - the Moon God.
