What remained unknown to Lin Xiao was that they stayed submissively silent because of his overwhelming expertise. Even if he had exacerbated their sufferings for times, they wouldn't have dared make a sound.

For their part, it had been an absolute honor for them to be granted the chance to test the containment of poison in the pellets at the risk of their own life. It would have disappointed Lin Xiao if they had let him down.

Both constantly writhed on the ground. In a short while, their revealed skin darkened the symptom of intoxication became increasingly obvious. Till then, Lin Xiao finally took out the antidote pellets and put them into their mouths.

It seemed that Lin Xiao enjoyed tormenting them. On the contrary, he had to make out whether the containment of poison was sufficiently high.

The results measured up to his expectation.

After taking the antidotes, they soon calmed down and the black tinge on their skin vanished right away.

Apparently, the antidotes started working.

Done with the experiment, Lin Xiao had achieved his goal. He apologized to the two assistants earnestly, "I'm dreadfully sorry about making you two suffer."

Wu Gui and Wang Di, who had been lying on the ground, rose all of a sudden and made a simultaneous response, "No, we didn't feel that way. Please continue to offer tasks of this kind to us in the future."

Lin Xiao felt tempted to get to the bottom of the reason why they were willing to make such cruel sacrifices. However, he caught himself on seeing their steadfast looks as if they would have committed suicide if he had rejected them. He only uttered, "Um, okay."

Something weird suddenly rang a bell and sent chills down Lin Xiao's spine. He thought to himself, shivering, "I didn't expect they are masochists."

After clearing his head, Lin Xiao asked, "How far are you with the practice of the Fire Control Mudras?"

On hearing this, both lowered their heads, feeling extremely embarrassed.

As being said, one of them boasted the Absolute-Yang-type physique, and the other Taoist-Fire both were perfectly suited for alchemy. Compounded with the incentive of Lin Xiao's unrivaled expertise, they have made insurmountable achievements.

Take Wang Di as an example, though he had never been exposed to the Fire Control Mudras, he had made a marvelous command of combinations of mudras.

Compared to The Fire Devil Hand allocated to Wang Di, Wu Gui's The Doctrines of Limbo was superior. Though he hadn't managed to learn the mudras combinations to the utmost extent, he had mastered thousands of variations.

Their progress was indeed commendable. However, compared to Lin Xiao, it was not much to be particular about.

Seeing them staying reticent, Lin Xiao didn't go further with his inquiry. As he knew that they were sufficiently competent for the refinement of the antidote pellets.

"I'd have to further verify the effects of the poisoned Most Refined Royal Pellets. Hence I'd like to ask you o help me with the antidote production,"Lin Xiao said.

Hardly had he finished his request, Wu Gui and Wang Di raised their heads, beaming with surprise.
