Silvery and viscous juice surged in the graphite crucible, and in the basement of the church, Ma Wei, who was covered with a veil, closed the lid of the pot and stretched out his hand to Geylan beside him.

"Hearttail grass."

Jaylan hurriedly handed over a dark green, finger-long, curly plant with many young shoots and golden cores.

It grows only at high latitudes, adapts to cold climatic conditions, and can survive even in snow-covered winters, does not rely on sunlight, but hides deep underground, and only emerges from the ground during the budding period.

Because the shoots are golden, many people mistakenly think that the bud core is the most precious part of the hearttail, but in fact, the most useful part of the hearttail grass is the inconspicuous rhizome, and the bud core is highly poisonous.

Ma Wei, who was wearing leather gloves, carefully plucked the golden shoots on the hearttail grass and threw them into the glass jar on the side for preservation, although the bud core of the hearttail grass was poisonous, but it could also be used to make potions, which was also valuable.

Picking off all the golden shoots, the hearttail grass became bare, Ma Wei picked up the knife and peeled off the green skin, revealing the white rhizome inside, and in the middle of the rhizome, there was a golden line.

The potion formula is very strict, and the dosage of the ingredients is clearly defined, for example, in the formula of high-grade potion mercury blood, you need 1 pint of high-purity mercury, 1 ounce of peeled rhizome of hearttail grass, half an ounce of white aphid resin, and one obsidian stone.

The quality and size of the Obsidian can affect the final product of the blood of mercury, and if it is the Obsidian left behind after the death of the Bone Giant, it can make the gods temporarily lose their power, and they will be paralyzed to the ground as if they had been drugged, making it difficult to move.

The Bone Giant was turned into powder by the Black Sun, and there were no Obsidian Stones left, and the Obsidian Stones collected by Jaylan were all from the Death Knight, an immortal created by the Bone Giant, whose strength and status were almost the same as those of the three generations of the Blood Clan, and the quality could only be said to be decent.

The mercury blood made from the Death Knight's Obsidian has extremely powerful lethality against the second-generation bloodline, which can make the second-generation bloodline such as Jaylan and Louise completely lose the ability to resist and be slaughtered by others.

Even the first generation of blood like Edward will be affected by the blood of mercury, and the specific degree of influence depends on the quality of the blood of mercury, the higher the quality, the greater the impact.

Weighing the grams, Ma Wei followed the steps on the "Potion Recipes", opened the lid of the pot, first threw the 1-ounce peeled rhizome of the hearttail into the mercury, then picked up the glass pestle, and began to stir the viscous mercury clockwise.

The white rhizome gradually disappeared in the mercury, and the golden lines in the rhizome gradually merged with the mercury, and the silver-white surface seemed to flow with golden light.

Seeing that the peeled rhizomes of the hearttail grass were all fused with the mercury that had been dried inside, Ma Wei stopped stirring, carefully twisted the glass test tube on the shelf next to the table, pinched the rubber ring, and dripped fourteen drops of dark blue resin into the pot.

Syllable!

As soon as the resin and mercury came into contact, there was a slight explosion sound, as if resisting the fusion with the mercury, rolling on the surface, like water droplets on a hot pan, refusing to blend in.

This is a normal phenomenon, Ma Wei quickly closed the lid of the pot, listened to the crackling sound in the crucible, walked out of the underground dark room, took off the mask and took a deep breath.

Mercury is poisonous, he has been in the confined space for too long, his brain is groggy, and there are already signs of poisoning, Jaylan and Edward are fine, they are not affected by mercury, but Mavi must come out to breathe.

】

Jaylan originally planned to make the blood of mercury by himself, but Ma Wei felt that this opportunity was rare and wanted to experience the feeling of making potions with his own hands, so he made Jaylan his deputy.

There's always a good thing to know, Ma Wei thinks.

After a few minutes of fresh air and a little more conscious in his drowsy brain, Mavi put on his mask again and returned to the basement darkroom.

The crackling sound in the graphite crucible has stopped, and when the lid is lifted, the dark blue white aphid resin has merged with mercury, and the four colors of silver, gold, blue, and gray are perfectly blended.

Then comes the final step.

Ma Wei sprinkled the finely ground soul obsidian into the pot, slowly poured the powder with one hand, and stirred quickly with a glass pestle in the other, so that the powder completely dissolved into the mercury, and in the process, the thick smoke rose from the pot, obviously not heated, but still heated rapidly.

Ma Wei held his breath, avoiding the rising white mist, and kept stirring, the mercury in the pot seemed to evaporate, and the water level dropped at a speed visible to the naked eye, when a whole Obsidian powder was poured in....

The liquid, which was originally mixed with the four colors, had become red, viscous like some kind of glue, and it was difficult to stir.

Seeing the silvery mercury turn crimson, Mavi's eyes lit up, and he pulled out the glass pestle and asked Geylan to bring the beaker, so that the made potion would naturally fall into the beaker along the glass pestle.

The most dangerous thing is the mercury vapor emitted by the evaporation of mercury, which is highly poisonous, and it will be tricked if you are not careful, and the difficulty of making it is not high, even a novice like Ma Wei can easily complete it.

"It's... This is the blood of mercury? Geylan held the beaker in both hands, as if he was afraid of falling and shattering, and looked at the viscous red liquid in the cup, and said in a trembling voice.

"According to the introduction in the "Potion Recipe Encyclopedia", it should be right." Ma Wei covered the pot, took Jaylan out of the basement dark room, closed the door and said, "In terms of dosage, there is no specific standard given above." ”

The "Encyclopedia of Potions Recipes" only writes the formula, but does not say the detailed dosage, only the sentence 'use according to the actual situation'.

According to the actual situation....

What is the actual situation?

The next generation of bloods?

But the problem is that Ma Wei doesn't know how much mercury blood can work on the next generation of blood!

If it is to kill Louise, then the more the dosage, the better, but Ma Wei wants to use the blood of mercury to treat the blood clan, this kind of behavior is probably not expected by the recorder and the creator.

"It's okay!"

Jaylan gritted his teeth and said, "I'll test the medicine for Louise!" ”

Without waiting for Ma Wei to dissuade him, Jaylan drank the red liquid from the beaker, and he swallowed 1 ear, that is, 148 milliliters of mercury blood.

Smack!

The glass beaker shattered against the solid stone floor, and Jaylan's body fell to the ground, his hands clutching his throat, his eyes wide open, his face pale, as if he couldn't breathe, and struggled in pain.

When Edward saw this scene, he frowned slightly, and wanted to come to the rescue, but was stopped by Ma Wei.

"We're going to record the complete symptoms of the next generation of blood after taking 1 and ear mercury blood." Ma Wei said in a deep voice, "Don't let Jaylan's efforts go to waste. ”
