As the so-called busy, since moving the experimental equipment back from the cave, Luo Lan seems to be fascinated, and whenever he has time, he will hold the experimental records and look through them. This experiment record contains a wide range of potions, including many potions that can be made by ordinary mages in addition to the necromancer's unique magic potions.

Luo Lan couldn't put it down, and in just a few months, his understanding of magic potions went from knowing nothing to being a beginner. Magical potions are profound and profound, and through the combination and ratio of different drugs, they can create potions with extraordinary effects, which is very useful to Luo Lan.

Although the role of the evolution system is irreplaceable, with the improvement of Luo Lan's physical fitness, the primary and intermediate evolution factors have no effect on his physique, and if he wants to continue to break through, he needs to find advanced evolution factors.

The system has not been upgraded for a long time, and searching for advanced evolution factors requires physical contact, which is too difficult, which greatly restricts the speed of Luo Lan's physique growth. However, the appearance of this experimental record opened a window for Luo Lan in the dark.

"I can use some common medicines to refine potions containing advanced evolution factors." Luo Lan's eyes were filled with ecstasy as if he had discovered a treasure.

It was too difficult for Luo Lan to create a potion formula, but it was much less difficult to configure according to the formula, and there were many potions in this experiment record that were effective for improving the strength of the body, and Luo Lan also found a reagent called dragon's blood potion in the cave.

"It's a pity that there is only one dragon's blood potion, but I don't know if the effect is really as magical as described." Luo Lan shook the crystal test tube in his hand, and a golden oily liquid emitted a silky fragrance like an orchid and musk.

"Regardless of the effect, this appearance alone is coveted." After preparing for such a long time, Luo Lan couldn't wait to try the effect of the potion.

Squinting the corners of his mouth and smiling slightly, Luo Lan no longer had any hesitation, raised his hand, and swallowed a ball of golden liquid into his abdomen.

The reagent turned into a clear stream in the mouth, rolling down the throat, like tasting the most mellow wine, quenching thirst and leaving a fragrant mouth.

However, Luo Lan's cautious expression did not relax in the slightest.

According to the records, this was just the last calm before the storm, and the dragon blood potion was mixed with all the blood and demon core of a ninth-level dragon demonic beast, and then refined with some other rare heavenly and earthly treasures, which naturally retained the unique fury of dragon blood.

Sure enough—

At the moment when the reagent reached the stomach, there was a sudden change, and the original coolness turned into a scorching heat, burning Luo Lan's stomach like a ball of magma.

"It hurts, it hurts!"

Even though he was already on guard, Luo Lan still underestimated the intensity of the pain, and he curled up on the ground like a boiled prawn, his whole body was red, and the slightest heat was rising.

"The fury of dragon blood is really not something that ordinary people can bear, no wonder there are no results in many experiments, this pain alone can torture people to collapse." Luo Lan struggled to reach into his arms while experiencing the feeling of being in pain.

Soon, a small grass from the blue was held in Luo Lan's hand, if Lin Lei was here, he would definitely be able to recognize at a glance that the blue grass in Luo Lan's hand was the blue grass he was looking for.

"Luckily, I was prepared!"

Luo Lan smiled and swallowed the Blue Heart Grass in his mouth, and suddenly the juice of the Blue Star Grass turned into a ball of cool gas flowing through Luo Lan's body, protecting his heart and blood vessels, and reducing the burning sensation of dragon blood.

Luo Lan had been preparing for several months but had been hesitant to swallow the dragon's blood potion, and it was not until yesterday that he finally found a blue heart grass that he made up his mind.

Even with the relieving effect of the blue heart grass, this pain is still unbearable for ordinary people, but fortunately, Luo Lan's physique is far beyond ordinary people, coupled with strong mental power, he persevered for an hour, and he did not faint.

An hour later, the pain receded like a tide, Luo Lan's muscles and bones made all kinds of strange sounds, and powerful qi and blood flowed in his body.

Luo Lan stared at the system screen, and the system could more intuitively show the changes brought to him by the dragon's blood potion.

Luo Lan: Terran Constitution: 7 Soul: 6 Agility: 8 Fighting Spirit: 8 Mana: 6 Evolution: 1264/10000 Status: Health. System Status: Intermediate Function: Can detect and absorb matter containing evolutionary factors within 10 meters of the subject.

"Shhhh

"It's crazy that it's so much more!"

Looking at the results of the system, Luo Lan immediately gasped, and a dragon blood elixir increased the evolution value by more than a thousand.

"If there are nine more reagents, wouldn't it be possible to directly advance to the eighth level, this ...... The effect is simply unbelievable. Luo Lan's eyes shone brightly, as bright as two searchlights in the dark night.

"However, this matter must be kept secret, especially not to let the Bright Sect get it."

Lin Lei and the Holy See of Bright Light are destined to break up, no matter from the perspective of personal relations or the general trend, Luo Lan will stand on Lin Lei's side without dispute.

Compared to the unavoidable purple jade cold chalcedony, the dragon blood elixir is simply too cheap, if the Holy See is allowed to obtain the refining method of the potion, this strength may increase geometrically.

In fact, Luo Lan was a little worried, there were many materials required for such a dragon blood elixir, each of which was worth millions of gold coins, coupled with the extremely low success rate of magic elixir refining, the price of a dragon blood elixir might not be cheaper than the purple jade cold chalcedony.

The dragon's blood potion completely stimulated Luo Lan's enthusiasm for studying magic potions, and from then on, he was even more obsessed with it.

Spring goes to autumn, after several cold and heat.

In the nameless canyon, the trees are lush and leafy, the scorching sun shines through the gaps between the leaves, and the wildflowers on the ground move to meet the dappled light and shadow. The golden retriever flutters happily among the wildflowers, chasing butterflies frolicking among the flowers.

Not far away, the velociraptor king Sangkun lay in the shade, his eyes looking in the direction of the cave from time to time.

In the cave, Luo Lan was carefully pouring a ball of green solution from the crystal test tube in his hand into the crystal cup next to him.

It was like water dripping into hot oil, and suddenly there was a sizzling sound, and a fist of light blue smoke was produced on the liquid surface.

"It's almost done!"

Luo Lan's eyes were full of joy, the long-prepared blue elixir was about to succeed, and he quickly reached out to put the lid on the crystal cup.

Tingting's curling blue smoke met the barrier of the lid, and immediately diffused in the gap between the cups, and the color became darker and darker.

Luo Lan's eyes stared at the cup without blinking, and his heart hung in his throat.

It took more than three years, Luo Lan read through the experimental record hundreds of times, starting with the most basic potion production, and finally entered the magic potion production room.

Although the Azure Elixir is the simplest among all the physique-enhancing elixirs, it is the most difficult magic potion that Luo Lan has configured so far, and it has failed dozens of times in a row before, and this time it is finally close to success.

"This time it must be successful!" Luo Lan yelled in his heart.

I saw that the originally increasing light blue smoke seemed to have broken through a certain street point in an instant, and suddenly condensed into several droplets of azure blue water, condensing on the lid.

"The blue potion is done!"

Luo Lan's heart suddenly bloomed, as long as he collected those few drops of azure liquid beads, he was done.

Just when Luo Lan was about to collect the liquid beads, suddenly-

There was an earth-shattering tremor outside the cave, and the liquid that had been attached to the lid shook violently.

"Don't!"

Before Luo Lan could react, he all fell into the solution.

Failed, failed in the simplest step, months of hard work were ruined. The anger in Luo Lan's heart can be imagined, like a volcanic eruption, roaring out loudly.

"Sankun, how did you guard the cave?"

"Young Master, it's a ninth-level demonic beast silver dragon, and a group of silver dragons are rushing in the direction of the canyon!" Sankun hurriedly transmitted, with infinite panic in his words.
