"The extract on the black man's spider venom claw-" He silently recalled the extraction process, then reached out from the table, took a test tube, and held a shiny silver surgical forceps in the other hand, and carefully clamped the two poisonous claws of the spotted spider, although it was invaded by external forces, its hideous long legs full of fluff, and it kicked weakly, but it still couldn't break free from the clamps of the surgical forceps.

Lin Meng put the test tube under one of the spider's claws very steadily, pressed it hard, and suddenly a stream of black liquid like ink slowly flowed into the test tube along the wall of the test tube, the smell was extremely fishy, he frowned slightly, and then a breeze appeared in the room, and the fishy smell was rolled straight out.

After repeating this a few times, the venom of one of the 'Black Man Spider's claws flowed into the test tube, he picked up the test tube and shook it, only to fill a small half, and then concocted it in the same way, he put the test tube on the other venom claw of the 'Black Man Spider', the gurgling black liquor was slowly flowing into the test tube, and not long after, the venom of the two claws had been taken out, and the liquid in the test tube in his hand was almost full.

He casually placed it on a shelf, and then picked up a black plant that looked like a crooked snake, and it seemed that the branches and leaves of the plant were fat and well-watered, and he held it. Viper grass's rhizome, Lin Meng's hand flashed with gold, and he cut it open, and suddenly a blue-green liquid accompanied by a strange fragrance came out of the wound, and was dripped into a beaker that had already been prepared by Lin Meng, and the plant shook like crazy in his hand, making a terrible scream, like a living thing, and the picture was extremely weird.

After dealing with the 'Viper Grass', Lin Meng spent most of the day processing the 'Snake Resentment Flower' and some other materials, looking at the stone platform full of many beakers and test tubes, all of which contained various materials, including a liquid that was bubbling black gas, a solution that was constantly rotating, and a powder that emitted a disgusting and foul smell......

After dealing with these things, he stood up and relaxed, recalling the steps of the configuration in his mind, and then he took out a 'magic return potion' and took it, quickly replenishing the mana consumed in his body, and then he casually took off the test tube containing the venom of the 'Black Man Spider' and placed it on a test tube clamp to fix it.

The blue mang flashed in his hand, and suddenly a refreshing coolness gushed out in his hand, he flicked his fingers, and the blue mang immediately shot towards the test tube, wrapping the test tube at once, the temperature in the test tube dropped sharply, and the wall of the tube began to freeze, and the venom originally contained in the test tube, under the low temperature of rapid freezing, actually began to shrink slowly, turning into a thick jelly-like blue substance, seeing this, Lin Meng's eyes froze, staring at it tightly, until he felt that it was almost, and immediately picked up a pinch of red powder next to him and carefully sprinkled it in the test tube。

Suddenly, the sound of 'Zizizi' sounded, and I saw that the blue substance in the test tube, as soon as it was stained with red powder, began to disappear at a speed visible to the naked eye, turning into repeated light smoke, and finally after a while, only one-third of the light blue solution remained, Lin Meng put him aside, and then began to move again.

Two days later, with the cooperation of Lin Meng and the earth, all the experimental materials in the room were turned into the contents of the beaker in his hand, and then he saw that he was holding a beaker in his hand, constantly shaking, containing half a cup of gray liquid, and some turbid things could also be seen floating in it, and the liquid at this time continued to exude a strange smell that he could not describe, not a foul smell nor a good smell, but a bit like the musk he had smelled before.

At this time, he stretched out his five fingers and grabbed the ice cube that had been placed until now, and he took it into his hand, staring at the ice cube, his eyes flashed, there was a drop of bright scarlet blood inside, which was frozen inside, but it was Christina's own blood.

The two most critical things in the configuration of this 'snake potion' are the 'snake resentment flower' and the blood of powerful snakes, because she has the bloodlines of extremely powerful creatures such as 'Snake Bloodline' in her body, so the blood of this powerful snake, she directly provides her own bloodline.

Staring at it, Lin Meng couldn't help laughing at himself, in order to get Christina's blood, when the two of them fled for their lives, he took advantage of her serious injuries and coma, and quietly collected a lot, he used his five fingers hard, clicked, and crushed the ice cubes, and then the red droplets inside dripped into the beaker with a ding dong.

Suddenly, the liquid surface, which was originally quite calm, was immediately like cold water poured into boiling oil, crackling, and a violent sound erupted, the whole liquid was in the beaker without wind and waves, and it rotated extremely quickly, bursts of black smoke, from the mouth of the beaker, gathered more and more, and lasted for a long time, and finally converged into a small black snake covered with colorful tattoos, I don't know if it was because of the addition of Christina's blood, Lin Meng looked at the little snake and felt that it was very similar to the dark snake that Christina turned into last time.

With a wave of his big hand, a breeze blew, and suddenly the black mist snake at the mouth of the bottle let out an unwilling hiss, and then slowly dissipated, and at this time, the liquid in the beaker had turned into a pitch black, ink-like thing.

"This is the 'Snake Elixir'?" he looked at the beaker in his hand, his eyes froze, and he shook the liquid in the cup, perhaps it had already reacted, and at this moment the black potion was no different from the usual potion, quietly contained in the beaker, and then he filled it in a potion bottle.

......

A week later, Lin Meng stood in a huge room in the 'Tower of the Underworld', he squinted and looked at the huge magic circle in the middle of the room, not so much a room, but a square This is more appropriate, a huge space, comparable to the Victory Square of the Red Castle, surrounded by thick pillars inscribed with dense runes, in a certain order, the magic circle in the middle of the square also came from time to time There were faint fluctuations.

He wore a night cloak to completely cover himself, and next to him stood Christina, too, dressed in a black cloak, who didn't want anyone else to notice her presence.

At this time, many wizards had already come to the square one after another, except for a few who were not surprised, the other wizards were all dressed like him, covered in black robes, and did not leak any breath all over their bodies.

After a while, few other wizards had come in from the square, and the rest of the wizards were in groups of three or five, perhaps companions who had been agreed with in advance, and there were also those solitary wizards who found a place to stay by themselves and not talk to the people around them.
