After Mlazi left, Merlin immediately set about modifying the spell to defend against the witch circle, although she had checked the entire witch circle, but she was still worried that the other party would leave some hidden gaps in the witch circle, so she arranged a guard puppet outside the valley and around the valley - this kind of alchemy puppet can not only be vigilant, but also has a strange appearance, especially since there is a witch circle near them, and the energy fluctuations emitted by them are almost negligible.

After arranging all of this securely, Merlin began to prepare her cultivation place...... There is no need to dig a hole, and there are three wooden houses in the valley, which are a little rudimentary, but they are enough for use. The energy particles in the valley were even richer than those in the rubic cubes, and the meditation was still in the valley, and she took out some furniture from the manor and placed them in the wooden house.

Victoria and their abilities are not only able to recover in the White Ghost, but the environment inside is also very beneficial to improving their strength, there are no accidents, Merlin is not ready to summon them, and the Sky Vision Phantom Snake, Night Falcon and Three-Eyed Hades have all been released by her, the valley is empty, with them, the vigilance is more rigorous.

If nothing else, the rest of the time should be relatively stable, but she still has things to do...... Merlin's hand flicked on the dimensional ring, and a box came out, and the lid of the box was opened, and inside were three test tubes containing silver potions.

This was found in the treasure trove of the Valley of Mysteries Academy...... In fact, in the treasure trove of the Valley of Mystery Academy, the largest amount of magic stones, magic crystals and some relatively scarce materials were collected, and many of the embalming witch arrays in the treasure house were destroyed due to the failure of time, and even some of the remaining witch weapons were also damaged. As for why there are so few, Merlin can also guess...... After the accident in the Valley of Mystery Academy, I am afraid that all the items that could be taken out to deal with the enemy have been distributed, and the rest are some items that cannot be converted into combat power in time.

However, there is something special about these three potions...... In the entire treasure house, there are only these three finished elixirs, and their value is naturally self-evident, but it's a pity that she doesn't know them.

This is not a strange thing, although she is proficient in potion refining, she is not specialized in potions...... Moreover, many of the formulas and related materials of the ancient potion school have been lost, so it is not surprising that she does not recognize the decrepit people.

After opening the test tube, Merlin probed her spiritual power into the potion swamp and immediately felt that it was full of surging life energy...... Although she sensed that this potion had great benefits for the human body, Merlin had no intention of trying it. On the one hand, it was impossible for her to rashly try a potion that she didn't know, and on the other hand, there were only three of these potions, and it was not worth it to waste one just to test its medicinal properties.

What should I do, and I don't have any information in my hand to verify, do I really want to take it...... But it's not realistic to have Merlin take a potion that doesn't know what to do.

Thinking of this, Mei Lin had a flash of inspiration in her mind, and secretly laughed that she was really confused, how could she forget that there was an ancient book among the trophies.

So Mei Lin hurriedly took out the ancient book from the dimensional ring...... As you can tell from the title of the book, this is a book about medicine.

After about a quarter of an hour, Merlin looked up, her face full of joy.

Life Extension Elixir!

Although Merlin had also thought that this potion was extraordinary, she had never expected it to be so precious.

It can actually increase the lifespan!

It's a bit against the sky.

Generally speaking, the lifespan of a wizard is very long. However, for a wizard, time is always not enough, and many wizards are stuck on a bottleneck and cannot get through, helplessly waiting for life to pass day by day. For them to give birth, every day of life is a possibility.

In the practice of wizards, every day is a race against time, which is incomparably precious.

The value of life extension agents...... It can well be imagined.

Merlin took a breath, this time, she really picked up the treasure.

Now that she understands the efficacy of the potion, Mei Lin is not busy swallowing it, she is still young and tight, and she doesn't need this thing for the time being.

In that ancient book, an almost complete potion inheritance was recorded, in addition to some ancient potion recipes, there was also a complete life-extending potion formula...... The most important thing is that in the previous sweeping operation, Mei Lin had taken the medicine garden of the Valley of Mystery Academy, which contained the main materials for refining life-extending potions, and although the other materials were still missing, it was not difficult to collect. In time, Merlin will be able to reproduce the life-prolonging potion. And the most valuable place for these three life-prolonging elixirs is the auction.

Merlin is sure that as long as this thing is auctioned, it will definitely sell for a sky-high price, and I am afraid that even sixth- and seventh-level wizards will spend a lot of money to bid for it.

But the more this happens, the more Merlin doesn't dare to make a move easily, because her own strength is too weak. Once the life-prolonging potion comes out, I'm afraid she will have to flee.

The experience during this period of time made Merlin realize a problem, that is, her combat methods seemed to be a little too little. Fortunately, this time, I got a batch of ancient witchcraft templates in the treasure house of the Valley of Mysteries Academy, and there are also some special potions in that ancient book, so I can take this opportunity to study them.

Before she can do that, though, she has some preparations.

After instructing the three pets, Merlin entered the rubik alchemy laboratory, she instructed Augustus to pay attention to the movement outside, she brought a grinding wheel to the front, and then took out a stone with a special bone,

The one with a dark color is a jackstone. This stone can store mana, and as long as it is attached to the skin, it can be absorbed through mental mobilization.

The second is a dark blue polyp. This stone can shield the psychic force from probing.

Merlin is going to cut and polish these stones to make two bracelets.

......

On a mountain path about a hundred miles from the castle of Carnzo, a cavalry force of twelve men was moving forward at a brisk pace. The leader is a middle-aged knight, and alongside him is a wizard apprentice. Behind him were ten samurai, all of them burly, strong and capable.

"Captain, it's just an abandoned mine, is it necessary to look into it?" asked a samurai.

They are the patrols of the Carenzo family, mainly responsible for patrolling the area around the castle and the family property, on the one hand, to avoid the involvement of spies, and on the other hand, there are many unsafe elements in the mountain, and their patrol is responsible for finding these unstable factors and solving them.

"If it's just an abandoned mine, you don't need to look at it. But if there are man-eating monsters in the mines, that's a different story. Captain Sylvie said with a gloomy face.
