Song Wen sat cross-legged, adjusted his breathing, and only after a moment did he place the pill in his mouth.
Once the pill entered his stomach, it was just like before, transforming into streams of heat that flowed throughout his body.
The spiritual power within his meridians began to surge wildly, swiftly spreading through his limbs and bones before finally returning to his dantian.
At the same time, the blood and qi within his body began to drain sharply, as though the pill's effect was to transform his blood and qi into spiritual energy.
The mysterious energy that had appeared before emerged once more, rapidly replenishing the blood and qi he had consumed.
Song Wen had always wanted to uncover the mysteries of his physical body, so from the very beginning, he had devoted part of his attention to observing the changes in his body.
This time, he finally noticed the source of that mysterious power.
It actually came from deep within the bones throughout his body—the essence blood stored within his bones was being released.
Could it be that the essence blood I devoured after killing those people was absorbed and digested by my body, becoming my own essence blood and hidden within me?
Essence blood is the essence of a person's life. It concerns one's health and lifespan. I wonder whether this essence blood can extend one's life.
Perhaps because Song Wen had devoured the essence blood of five people, the essence blood energy that emerged this time was far greater than before.
This kept Song Wen's blood and qi in a constant state of balance, without any obvious signs of weakness.
This made Extreme Yin, who stood nearby, exceptionally excited. After years of attempts, he had finally glimpsed the dawn of success.
Song Wen, who was refining the pill's medicinal power, was not nearly as optimistic as Extreme Yin.
Damn it, what's going on? Why is this pill's medicinal power more than twice as strong as last time? Just how did Extreme Yin refine these pills? Their effects are so unstable.
Good thing I devoured the essence blood of Gou Hang and the other two. Otherwise, I might not have been able to endure it.
As Song Wen silently refined the medicinal power, he cursed inwardly.
The stronger the pill's medicinal power, the more blood and qi it consumed, which meant the more spiritual power it converted for Song Wen.
Without realizing it, Song Wen's cultivation suddenly soared. He directly broke through Qi Refining Level One and reached Qi Refining Second Layer.
"Success!"
Extreme Yin was beside himself with excitement. His eyes widened as he muttered in a low voice.
Even his hands trembled with excitement. He wanted to immediately try swallowing a pill himself and break through the cultivation bottleneck that had trapped him for years.
However, Extreme Yin ultimately suppressed the urge. To be safe, he decided to wait until Song Wen had completely refined the medicinal power and observe the situation before making a decision.
Half an hour later, Song Wen had completely refined the pill's medicinal power, and his cultivation stabilized at Qi Refining Second Layer.
Song Wen's eyes gleamed with excitement, carrying both the relief of surviving a calamity and the joy of breaking through in cultivation and gaining greater strength.
"Master, there's no problem with the pill. My cultivation has also broken through."
Extreme Yin nodded and grasped Song Wen's wrist, using spiritual power to inspect Song Wen's body.
In his perception, there was nothing wrong with Song Wen's body, and his cultivation had genuinely reached Qi Refining Second Layer.
All of this showed that he had successfully refined the Blood Qi Pill—a Blood Qi Pill capable of helping people break through their bottlenecks.
"Good!" Extreme Yin said with a smile. "This is truly wonderful."
"Song Wen, go down and rest. Your master is going into seclusion to break through. Everything in the courtyard will be your responsibility. At the same time, you must guard me and forbid anyone from going up to the second floor."
Song Wen hesitated for a moment, then said expectantly, "Master, may this disciple receive the antidote to the Seven-Day Heartbreak Pill first?"
A flicker of killing intent passed through Extreme Yin's eyes, but he quickly concealed it.
"After your master emerges from seclusion, I will give you the true antidote to the Seven-Day Heartbreak Pill."
Song Wen clasped his hands joyfully. "Thank you, Master. This disciple will certainly guard you well and will not allow anyone to disturb your breakthrough."
With that, Song Wen turned and went down from the second floor, standing motionlessly outside the wooden building.
Extreme Yin rose and glanced at Song Wen below, a cold smile curling at the corner of his lips.
"Once I break through to the Qi Refining Middle Stage, you will be useless."
Extreme Yin shut the door and began meditating to regulate his breathing. He was in no hurry to take the pill. He wanted to adjust his essence, qi, and spirit to their absolute best state before taking it, so that his chances of successfully breaking through would be greater.
Extreme Yin spent several hours before bringing his essence, qi, and spirit to their peak. By then, it was already deep into the night.
In his perception, Song Wen was still dutifully guarding below, not having taken a single step away. During that time, Aunt Chen had come twice to deliver food, but Song Wen had turned her away both times.
"What a foolish yet dutiful person. It almost makes your master feel guilty about killing you."
Extreme Yin no longer paid attention to anything else. Opening his mouth, he swallowed a Blood Qi Pill.
The violent medicinal power erupted in his stomach in an instant, transforming into streams of searing heat that rapidly rushed into his meridians.
At the same time, vast streams of spiritual power came into being from nothing, appearing within his meridians.
Extreme Yin hurriedly circulated his cultivation technique, attempting to refine all that spiritual power and use it to help him break through his bottleneck.
"What is going on?"
Suddenly, Extreme Yin discovered that something was wrong.
He sensed that the medicinal power was rapidly consuming his blood and qi.
"How is this possible? Song Wen clearly did not consume any blood and qi when he took the pill."
Extreme Yin could not understand the reason, but the arrow was already on the string; everything was beyond his control now.
He could only grit his teeth and continue refining the pill, hoping to exhaust its medicinal power before his blood and qi were completely depleted.
He no longer held any hope of breaking through to Qi Refining Fourth Layer. As long as he could stay alive, that would be enough.
As the medicinal power was digested, his blood and qi deficit grew increasingly severe. As his blood and qi supply became insufficient, his body rapidly weakened.
At this moment, he felt the pain and terror of those people he had once used to test his medicine.
