After Chu Yu caught the poison, the people of Baili once again witnessed the strangeness of their young lady.

I saw Chu Yu walking cautiously, letting the ghost fire float in the direction of her movement.

After a while, a series of ghost fires followed behind Chu Yu like a string of pearls.

As far as Chu Yu walked, they floated as far as they wanted, which was very interesting.

Chu Yu saw that it was almost over, opened the lid of the glass bottle, and harvested one ghost fireball at a time.

The ghost fire did not resist either, and let it be put in the bottle.

Fortunately, the people of Baili had refined enough glass bottles for Chu Yu at the beginning, otherwise they would really not be able to fill so many ghost fires today.

Although, nearly 100 bottles of glass bottles with blue light are placed on the ground, just like fireflies, which is very dreamy and wonderful.

However, as soon as they got closer, they could feel the yin qi that they collectively emitted, which made the Baili people shudder.

"Miss, what are you doing with all this fire?" asked Baili Ling Tian.

The fire was very strange, and it was blue, and the temperature was comparable to ice, which had never been seen before.

To others, ghost fire may be an ordinary chemical phenomenon in nature, but for her, it is indeed a rare treasure.

"Refining a new type of poison pill!" Chu Yu replied generously.

Ever since he saw the ghost fire, a bold idea had been circling in Chu Yu's mind.

In her previous life, she had seen a record in a wild book that if she used ghost fire to refine poison, the poison would bring its own yin qi.

As long as it is poisonous, there must be a solution, but once the yin qi enters the body, it can no longer be eradicated, and it will remain in the body forever.

Yin Qi is not fatal, but too much Yin Qi will cause Yang Qi to weaken, and no matter how strong a person is, he will gradually become weak and eventually die of exhaustion.

In his previous life, it had long been a legal society, not to mention mass graves, and even patches of graveyards were rarely seen, so Chu Yu had never had the opportunity to see ghost fires.

If I am lucky enough to see her tonight, she will definitely not let it go.

After collecting all the ghost fires, Chu Yu was already tired and out of breath.

"Miss, these glass bottles are guarded by us, you better go first to the tree cave to rest", Baili Ling Tian looked up, there was still an hour before dawn, Chu Yu had not slept for nearly a night, and hurriedly urged her to rest.

"The work is not finished yet, I have to hurry up and refine the poison."

Ordinary fire cannot be burned without oxygen.

The ghostfire left the gray mist that permeated the place, and it wouldn't be long before it would disappear.

Therefore, the glass bottle can only temporarily prevent the ghost fire from drifting around, but it cannot be stored for a long time.

She'd have to hurry up and use them up before they're gone.

After speaking, he took out an ordinary medicine refining tripod and experimented with the poison collected in Qianlong Mountain last time.

The reason why Chu Yu never used the Innocent Ding to refine poison was because he was afraid that over time, the toxins would slowly penetrate into the Ding, which would bring trouble to the refining of medicine in the future.

Moreover, Liu Yun, the former owner of the Wuxie Ding, I don't know if he is still alive, he uses it to refine poison at will, which is disrespectful to his predecessors.

This time, Chu Yu did not refine complex poisons, and chose the most basic practice.

Fortunately, she adopted a conservative plan, otherwise this little ghost fire would not have lasted until the end of the poison refining.

During the entire poison refining process, I saw Chu Yu quickly pour the ghost fire in the glass bottle into the Ding furnace, and every time he just poured it in, the ghost fire looked like it was dying.

Whether it is an open flame or a ghost fire, once the fire in the Ding furnace is extinguished, the refining of poison will definitely be terminated, and this time it will be considered a failure.

Therefore, from beginning to end, Chu Yu had no intention of taking into account the situation of refining toxins and Cheng Dan above.

As a result, in the end, Chu Yu could refine the basic poison pill with his eyes closed, but this time he actually only refined four of them, and they were all lower-grade pills, and the others became black scum.
