The branches of the sacred tree, lamp oil, animal bone powder, and the blood of monsters are the basic elements that make up the holy oil, and on the basis of these materials, alchemists are constantly adding new ingredients to refine more powerful exorcisms.

Farro generously provided his alchemy laboratory, and he admired Anling's ambition, because usually an apprentice-level alchemist could handle two materials, these four materials look simple, but the proportions must be accurate, otherwise they will only generate worthless garbage.

An Ling saw that the alchemy in her sub-class panel was lit up, and in this game, there is no one-click refining option, and the player must make it in a professional scene according to the prescribed materials.

In order to facilitate his students' understanding of animal bone powder and monster blood, Farro took out the popular science books on pharmacy such as "Research on Beast Bone Powder" and "Investigation Report on Monster Blood" in the library.

An Ling first soaked the branches of the sacred tree into the vessel, and then turned the book.

According to the process of making the holy oil, the branches of the sacred tree need to be soaked in the lamp oil for five hours before the next step of production begins.

Seeing that the situation had stabilized, Gu Yun returned to Emilian's potions shop.

Along the way, I met a lot of players, and more than 20 players added a unique scenery to the holy capital, and their biggest feature is that they can be recognized at a glance.

In particular, there are many people who have become monks and bald heads in order to increase critical hits or change jobs and hide professions.

The potions shop is still as overcrowded as ever, in this world full of monsters, injuries and illnesses are commonplace, and Emilian seems to have no concern for her patients, almost all the drugs are concocted by the schoolboy alone, and only when there is an incurable disease does she need to consult Emilian a few words.

Gu Yun suspected that Emilian's purpose in finding this junior apprentice was probably to make herself more relaxed.

"You're here."

Hearing footsteps, Emilian continued her research without raising her head.

The blood samples taken earlier were divided into three and placed in different petri dishes, and Gu Yun noticed that two of the petri dishes had been studied and labeled as they should be.

"I've heard that you've visited Farro."

Among the injured people outside the door, there were many guards from the inner city, and Gu Yun's bald head was very good, and they had been chattering outside the door about all the topics about the bald head and Gu Yun.

"What are the results of the study?"

Gu Yun cut straight to the point, he didn't have much time to stay here, once An Ling mastered the method of making holy oil, he would directly bring the holy oil to visit Su Wen.

Giving the blood to Emilian for research is actually not much different from the existence of shapeshifters, and what he wants to know is the reason why the Protoss call them demons.

The elder said that the Protoss and the Demon Race are just titles, and they have no substantive meaning, and the essence of what it shows is that they have stood on the opposite side of the Protoss since they were born.

And when he ascended to the dome of the sacred tree and entered the kingdom of God in the mouths of believers, he could not get a definite answer to this question, because the relationship between the two had been determined much earlier, more than a thousand years ago, and in fact, the gods of that era did not know the reason for such a definition.

"It's amazing, your blood is much more useful than I thought."

Emilian spoke, "I used the first blood sample on the monster, and the test subject who drank the blood disintegrated and died in less than a dozen seconds, and your blood is equivalent to deadly poison to some, if not most, monsters. ”

The premise of all her research is based on the tacit assumption that Gu Yun is from the south.

Emilian has never had the opportunity to come into contact with real Southlanders, but both the Misty Mountains Hermit Society and the Inner City Library have a lot of books about the Southland.

The navigators brought back a lot of news from the south, and in the logbook, they described the southerners as a wild tribe, just like the humans of primitive societies, who did not establish a kingdom, did not have a strict and systematic system, but only a union between tribes.

There are no witchers in the south, and they have no faith, and they have survived through the long battle against monsters through their own instincts.

This actually reveals a lot of implicit news - for example, the people of the Southland must rely on other forces to fight the monsters without the help of the Divine Tree and the Divine Creation Spell.

Her potions had never been able to explain the essence of spells and the Divine Tree, this power was above knowledge and could not be solved by existing wisdom, and Gu Yun's blood had the same point.

"Do you usually use your own blood to fight monsters?"

"No, not all people's blood has this effect."

The elders had said that only his blood was special, but never told him what made it special.

"Well, that's normal."

Emilian nodded, if all the southerners only needed a little blood to destroy the monsters, then the monsters of that continent would probably have been extinct long ago, "On this basis, I have conducted further research. ”

Potions is a fundamental theory, and her research does not stop at appearances, but also the reason why these blood samples can cause the death of monsters.

"I fused a second blood sample with a few samples of the virus, and as I expected, your blood killed the virus very quickly, which means that if used correctly, your blood can be a miracle for treating incurable diseases."

"I know that the elders used to use my blood to treat some people's ailments."

"The point is the reason - why can your blood save people even if it can kill monsters? Based on the above two experiments, I suspect that your blood is not actually killing the monster itself, but the creation of the gods, which explains both reasons and validates my previous thoughts. ”

Emilian had always been skeptical of theology, especially the claim that God created the world.

But one thing she was sure of now was that whether humans were created by gods or not, the monsters entrenched outside the city must have been made by gods.

He seems to have created danger and given them the means to fight it in exchange for the trust of believers.

This is perhaps the essence of spells studied by all schools of learning.

And Gu Yun, who has the power to eliminate these creations, must naturally stand on the opposite side of him.

"So in your doctrine, where did these monsters come from?"

Listening to Emilian's words, Gu Yun suddenly became a little curious.

"It's another god called 'Calamity', and in the collection of the Kiriyama Hermit Society, 'Calamity' was exiled by the people forever because of the natural calamity."
