There are four types of crystals. The higher the grade of the crystal, the better its quality. However, top-grade crystals are extremely rare. Therefore, most spiritual cultivators only know about some low-grade crystals but are unaware of the differences between them. Super experts, on the other hand, are very clear about the crystal grade classifications. After all, these are not things that ordinary people can easily possess. Qiu Ling'er's knowledge of these things stems from the four major forces she joined while in the Crimson Blaze Plains...

She couldn't help but think of Tie Yulinglong, that ruthless woman, and the thought sent chills down Qiu Ling'er's spine.

Coming to her senses, Qiu Ling'er took out a mid-grade crystal and prepared to absorb it.

However, to her surprise, as soon as she put the crystal in her mouth, a sharp pain instantly spread from the tip of her tongue throughout her body, causing her great pain.

Clenching her teeth and enduring the pain, Qiu Ling'er continued to swallow a mid-grade crystal. However, this time, she finally could not bear the torment and let out a scream that echoed through the sky.

Qiu Ling'er clutched her chest in pain and collapsed onto the bed.

Shortly after, a trickle of bright red liquid dripped from the corner of his mouth...

What's going on? Could this be poison? Qiu Ling'er wondered to herself.

Thinking of this, Qiu Ling'er quickly checked her internal condition.

Just as I expected...

I was indeed poisoned, and quite severely so.

Fortunately, it was just a Soul-Devouring Powder. This poison only prevents the poisoned person from using spiritual power, and there is no danger to their life.

"Good heavens, so this is where I was waiting."

Qiu Ling'er said angrily.

She knew she had been tricked by Qiu Feng.

"That damned old bastard, how dare he scheme against me! Since you poisoned me, don't blame me for retaliating."

As Qiu Ling'er thought about it, the resentment in her heart dissipated considerably.

She was initially shocked to see the high-grade crystal, but she didn't expect that the crystal would be poisoned. She was caught off guard and fell victim to the poison.

However, Qiu Feng never expected that Qiu Ling'er would be able to cure the poison.

Actually, we have to thank those chases on the Crimson Blaze Plains. It was those chases that led Qiu Ling'er to start researching poisons; otherwise, she would have really been in trouble today...
