The alchemy hall was filled with the smell of elixirs.
In the alchemy hall, there are some alchemists who are constantly controlling the flames of the alchemy furnace and are refining alchemy.
This place has not been quiet for a long time. Since the war started, the Alchemy Hall has been producing a large amount of elixirs every day to supply the defenders.
Many of the people sitting in the alchemy hall are not alchemists certified by the Alchemy Alliance. Some only know how to refine a few specific types of elixirs, and their levels are even more uneven.
There is still a high failure rate when making alchemy here.
What's more, refining alchemy every day requires a lot of mental energy. Many alchemists often stay here for dozens of days, and their eyes are already red and bloodshot.
"They finally used this trick."
Lu Yu's consciousness looked at the poisonous mist floating in the distance and sighed.
When the two armies are fighting, only in the most dire circumstances will the tactic of poison attack be used.
Because this will be a very bad start. Once poison attacks are used, both sides will do whatever it takes, and more people will die in the end.
Evil cultivators have no such concerns at all. They act to achieve their goals and can use various means.
"From today onwards, I will be refining alchemy in seclusion. No one is allowed in." Lu Yu turned around and went to the alchemy room.
Because of Lu Yu's order, no one dared to disturb him again.
In the empty alchemy room, only Lu Yu sat alone.
"The poison of the Inferi is also mixed with more than a dozen other poisons. I'm afraid this is just the first change. They are not only planning to use the poison to knock on the city door, they are also preparing to control the Inferi."
There was a dark green aura floating in Lu Yu's palm.
This breath is extremely violent, constantly impacting the surrounding area. However, there seems to be an invisible wall surrounding it, making it impossible to escape.
Lu Yu carefully analyzed the properties of the elixir, thought for a moment, and did not make the elixir rashly.
This was not the outside world. Lu Yu knew that all the examiners, including the prince, were looking at him.
In Lu Yu's mind, he still remembered that there were more than a dozen pills that could break this poison.
However, Lu Yu could not use those pill recipes to refine it.
Most of these poison-busting prescriptions were created by him in his previous life, or were treasured prescriptions in the palace.
There are many knowledgeable Hanlin and Confucian scholars among the examiners. They will definitely recognize what kind of elixir Lu Yu is refining.
By then, someone will definitely investigate how Lu Yu obtained these pill recipes, and there will be more trouble waiting for him.
If it can be said that the calligraphy and painting methods that Lu Yu used before can be covered up by his identity as a disciple of Literary Sage, then the alchemy incident may not be explained by this reason.
However, this is not impossible.
Lu Yu looked at the poison in his hand, and his mind began to think quickly. Countless possibilities for alchemy were constantly being formed and overturned in Lu Yu's mind.
No one knew what Lu Yu was thinking about.
Even they probably couldn't imagine what Lu Yu was thinking now.
He wants to create a prescription!
A prescription that can eliminate this evil poison attack once and for all!
High in the sky, all the examiners looked at Lu Yu with bated breath.
From their perspective, the outside of Lingzhou City has been completely shrouded in a thick poisonous mist. Wherever it passed, all life was plundered, and all living things were poisoned to death!
This has reached the final moment of life and death.
