In the courtyard of Qin Clan Chief Qin Lin at Qin Clan Manor, everyone waited anxiously.

The poison Qin Lin was poisoned with was a slow-acting poison. Qin Hongbing added only a very small amount to the pill each time. During cultivation, the poison circulated throughout the body's meridians and bones with the flow of true qi. Once the poison took hold and invaded the heart meridian, there was no antidote.

When Danqing told Qin Lin about the poison he had been poisoned, Qin Xin had no intention of letting the culprits off the hook, which led to the bloody scene that followed.

"Fortunately, the toxins had not yet invaded my heart meridian, and I have forcibly expelled them. However, I will never be able to use my true qi again, and my blood and qi will be completely burned away. I will only have three years left to live, unless I find some pills that can extend my lifespan."

Old Mo put Qin Lin's hand back under the covers, speaking thoughtfully, seemingly longing for the elixir that could extend lifespan.

The lowest grade of pills that can increase lifespan is grade seven. They are hard to find even in the Central Plains, let alone the Eastern Wilderness.

"Boy, I'm going back to the Martial Arts Hall to rest first. Come find me when you're done."

Old Mo did not urge Qin Xin, but turned and left first. He knew his own condition very well, and even somewhat doubted that Qin Xin could help him get rid of his hidden ailment.

While Elder Mo was treating Qin Lin, Qin Xin accidentally saw Elder Mo's arm. Black lines, like branding marks, were constantly devouring the blood and energy in his body.

"Um."

Qin Xin nodded gently, then came to Qin Lin's bedside. Looking at Qin Lin, whose hair was even whiter and whose face was full of wrinkles, he felt a pang of pain in his heart. After all, he had grown up by Qin Lin's side, and it would be impossible for him not to have feelings for him.

Qin Lin remained unconscious for a long time. Qin Qianfan took Tie Niu and others to sort out some family affairs. Qin Xue's cultivation level became unstable due to excessive use of her true energy. Only after being scolded by Qin Qianfan did she return to her room to heal her injuries. As for Hua Jin and Mao Ruijin, they stayed in the guest rooms in Qin Lin's courtyard.

Qin Xin stayed by Qin Lin's side, and after taking the Qi-restoring pill, he sat cross-legged on the ground to cultivate.

It wasn't until the morning light of the next day fell on his face that Qin Xin's eyes twitched slightly. His two eyes, one blue and one red, suddenly opened, a golden glint flashing in his pupils before returning to normal in an instant.

Qin Xin was quite exhausted from this battle, but his third main meridian was showing signs of loosening.

The surrounding spiritual energy suddenly converged on Qin Xin, and under the absorption of the Black Stick Martial Spirit, it was continuously transformed into true energy and poured into the dantian of the Wood and Fire Martial Spirit. When it reached the critical point, Qin Xin hurriedly turned his true energy to break through the third main meridian. Under the cleansing of the powerful true energy, the main meridian was instantly opened, and he stepped into the third level of the Innate Realm.

Qin Xin opened his eyes and slowly exhaled a breath of turbid air, then sensed the changes in the martial spirit and the spiritual consciousness in his Niwan Palace.

After killing Qin Yangxu and the others, the fragments of the martial spirit were all swallowed by the Spirit Devouring Stone. Part of the energy transformed into spiritual consciousness during the operation of the Supreme Divine Evolution Technique, while the other part was absorbed by the Black Stick Martial Spirit.

Qin Xin's Black Stick Martial Spirit is currently only three stars. To break through to four stars, he would need even more energy, but Qin Xin is not in a hurry.

Looking at Qin Lin lying on the bed, whose breathing was steady and whose face had regained some color, Qin Xin breathed a slight sigh of relief, but was still somewhat worried, especially since Qin Lin only had three years left to live.

He got up and left the room, switched shifts with Qin Qianfan, and then returned to his own courtyard.

After washing up and exchanging a few words with Zi Ling, he hurriedly headed to the clan's martial arts hall.

Although Qin Xin already knew how to solve the hidden ailment on Elder Mo's body as instructed by Dan Qing, he was still somewhat uneasy in the face of a Yuanfu Realm expert because he was a novice.

And so, Qin Xin muttered to Danqing in his mind as he walked toward the Martial Arts Hall, and before he knew it, he had arrived at the gate of the Martial Arts Hall.

"Come in!"

Mo Lao's aged voice came from inside the hall.

Qin Xin took a deep breath and stepped into the gate of the Martial Arts Hall.

Qin Xin noticed that the black patterns on Old Mo's body had begun to spread towards his neck, and the blood and qi in his body were being continuously devoured. A faint aura of death emanated from the top of his head.

"Please sit down."

Old Mo gestured for him to sit down, then opened his eyes and scrutinized Qin Xin.

"Senior Mo's hidden ailment must be caused by the cultivation technique he practiced."

Qin Xin spoke up after Danqing's prompting.

“Naturally, this hidden ailment will continue to grow stronger as my cultivation level increases, and it is now impossible to suppress it.”

Old Mo spoke without any reservations.

"There is a way, but it might involve considerable suffering," Qin Xin said calmly.

"There really is a solution."

Old Mo was overjoyed and momentarily lost his composure. He had never imagined that this little fellow at the third level of the Innate Realm would actually have a way to help him.

"Use fire to drive away disease!"

The moment Qin Xin uttered those four words, Old Mo's expression suddenly paused, as if he were sizing something up.

Using fire to expel disease, as the name suggests, involves using flames to burn away the black patterns in Old Mo's body, much like refining elixirs. However, this is extremely dangerous, as the flames need to enter the meridians. If the person controlling the fire has malicious intentions, it could damage the meridians or even endanger his life.

"Are you an alchemist?"

Old Mo asked in confusion, as he was familiar with this method, but only extremely powerful alchemists could do it.

"Yes, if you can trust me, senior, I will do my best."

Qin Xin didn't offer much explanation. He could be considered a first-grade alchemist now, but he was absolutely certain that the person controlling the fire-based speed boost was not him, but Dan Qing.

Old Mo thought for a moment, then sighed softly, as if he had come to terms with it.

“In that case, we’ll do as you say. I’m already half-dead, what do I have to fear?”

A long-lost smile appeared on Old Mo's face. Perhaps it was because the hidden ailments caused by his cultivation over the years had brought him too much pain. Now that there was a solution, he was able to relax. Or perhaps he didn't want to put pressure on Qin Xin.

After seeing that Elder Mo agreed, Qin Xin flicked his fingers and his true energy transformed into a blazing pale yellow flame, and then asked Danqing to help him control the true fire.

Sensing the sudden change in Qin Xin's aura, Elder Mo frowned slightly, but didn't think too much about it. He lightly traced a wound on his arm with his fingers.

Seeing this, Qin Xin pressed his fingers on Mo Lao's wound, and the golden life fire, against his will, mixed with Qin Xin's pale yellow true fire and entered Mo Lao's meridians.

The immense pain made Old Mo gasp; the pain from using fire to expel the disease was dozens of times greater than that from scraping the bone to remove poison.

After the flames entered the meridians, under Danqing's subtle control, they directly rushed towards the location of the black patterns.

Under the intense heat, the black patterns began to loosen, and a wisp of black smoke even emerged from Old Mo's body.

Upon noticing the change, Old Mo's face lit up with joy, knowing that the method was indeed effective. Even though the pain in his meridians was so intense it made him faint, he gritted his teeth and persevered.

A quarter of an hour later, Qin Xin suddenly withdrew the flames and let out a long sigh of relief.

"Continue."

Old Mo was somewhat excited. With the disappearance of the black patterns, he could feel that the deathly aura emanating from his body had lessened.

"I'm only at the third level of the Innate Realm, how could I possibly last this long?" Qin Xin said helplessly.

"Haha, let's rest first, no rush."

Old Mo's face showed a long-lost smile, just like that of an old child.
