Even if Jiang Tianxia ultimately didn't reveal the location of the Treasury Pavilion, it made no difference to Zhang Yang; with the Treasure Rat Wuying present, finding it was never an issue. The most crucial thing, the matter Zhang Yang most wanted to know, had already received its answer.

A descendant of the Medical Saint Zhang family… A cold glint flashed in Zhang Yang’s eyes. He had always suspected that the remnants of the Huyan family were responsible for poisoning Mi Xue, but he never imagined it would be someone claiming to be from the Medical Saint Zhang family.

Could the Medical Saint Zhang family have another lineage? Zhang Yang gave a self-deprecating laugh; that was utterly impossible.

Thinking carefully, if there was any connection to the Medical Saint Zhang family and someone who held a grudge against him, it could only be that Zhang family member from the Huatuo Residence who once tried to harm him and seize the Zhang family’s secret formulas. Although Zhang Yang hadn't met the young man surnamed Zhang—who failed in his scheme only to be imprisoned in the underground water dungeon by the Jiang family—he could already guess his identity.

This person was likely a survivor from the Huatuo Residence Zhang family. Jiang Tianxia was dead, and Jiang Zhiguo had been poisoned to death by Lightning’s toxic mist.

The two most powerful experts of the Jiang family had both perished outside the villa doors. The remaining Jiang family members who fled inside would certainly be no match for Yan Liangfei, aided by Lightning and Wuying.

Considering the unfortunate encounter of brothers Jiang Anshou and Jiang Anhhu with Zhang Yang right outside their mansion gate, the Jiang family was now facing the certainty of complete annihilation. Zhang Yang stood up, preparing to enter the villa.

Whether that young man was indeed a survivor from the Huatuo Residence Zhang family would become clear once he reached the underground water dungeon and saw him. “Ding-dong!” Just as Zhang Yang stepped onto the villa grounds and prepared to enter the main door, that familiar system notification chimed in his ears once more.

He hadn't expected the Divine Hand System to suddenly appear in his mind at this moment. “Congratulations to the Host, for completing the mission to save the Yan family.

The mission reward is effective immediately, directly raising Yan Liangfei’s loyalty to the Host to 70 points.” So, wiping out the Jiang family completed the mission to save the Yan family. This meant Yan Liangfei had already killed all the Jiang family remnants inside the villa and exacted his great revenge.

Now, Zhang Yang was no longer in a hurry to enter immediately. He brought up the system interface and reopened the mission log.

The mission to save the Yan family was now listed under the completed section. With a thought from Zhang Yang, Yan Liangfei’s profile reappeared before him beneath the saved mission, “Saving the Yan Family.” Seeing this, Zhang Yang was astonished again.

After Yan Liangfei’s name, it was noted that his internal energy had reached the late stage of the second layer of Inner Strength. Zhang Yang was acutely aware that before Yan Liangfei entered the villa, he was still that rash young man at the early stage of the second layer of Inner Strength.

Although later, fueled by his resentment and the obsession for revenge, his internal energy had vaguely approached the middle stage of the second layer during his fight with Jiang Tianxia, he hadn't truly achieved the strength of the middle stage. In essence, after his great revenge was complete, Yan Liangfei’s strength broke through consecutively, jumping straight to the late stage of the second layer of Inner Strength!

Breaking through multiple times in nearly an instant, this rate of advancement surpassed even Zhang Yang’s, causing him to click his tongue in amazement. Regardless of what happened inside the villa, Zhang Yang couldn't help but exclaim that anyone possessing one of the Five Great Cultivation Physiques was truly a genius in cultivation, especially the First-Line Golden Pupil Body, which was constrained by a congenital lifespan limit—that was truly astonishing!

He couldn't even imagine what heights Yan Liangfei's cultivation achievements might reach in the future if he weren't shackled by that congenital lifespan. However, since Yan Liangfei’s loyalty to Zhang Yang had risen to 70 points, Zhang Yang could fully consider taking him as a disciple and allowing him to join the Medical Martial Sect.

Then, the higher his future achievements, the more renowned the Medical Martial Sect would become in the cultivation world. Drip, drip… The sound of dripping water coincided with slow footsteps emerging from within the villa door.

Zhang Yang withdrew from the virtual screen of the Divine Hand System and peered inside the villa. A figure covered entirely in blood appeared at the entrance.

Not only the clothes but also the face and hands looked as if they had just endured a torrential downpour of blood. Coupled with those crimson eyes, the sight was quite frightening.

“Yan Liangfei?” Zhang Yang called out softly, frowning slightly. Yan Liangfei’s current state seemed rather bizarre.

Swish, swish! Two afterimages shot out from beside the blood-drenched Yan Liangfei in the blink of an eye.

They were the little ones, Lightning and Wuying. Upon seeing Zhang Yang, they didn’t leave to return to his side but instead stayed on either side of Yan Liangfei, staring at him with intense vigilance.

“Hoo… hoo…” The blood-soaked Yan Liangfei’s crimson eyes lit up when he saw Zhang Yang. He raised both hands, forming claws with his fingers, adopting a bloodthirsty posture as if ready to kill.

Only after clearly seeing it was Zhang Yang did he open his mouth, his Adam's apple bobbing up and down several times, seemingly wanting to say something but failing to utter a single word. Then, Yan Liangfei walked to a spot a few paces away from Zhang Yang and immediately knelt down on both knees.

Thump! This kneel struck the villa floorboards with such force that it gouged out two shallow depressions, the cracks spreading like a spider’s web.

Zhang Yang’s gaze sharpened. He casually retrieved two silver needles from his canvas bag, held one in each hand, spread his arms, swooped forward, and plunged the two silver needles into Yan Liangfei’s left and right temples in the first instant!

Lightning and Wuying, the two little ones, understood exactly what Zhang Yang was doing. They stood guard on either side, effectively protecting Zhang Yang’s process.

Seeing Yan Liangfei in this state, Zhang Yang inwardly sighed repeatedly. The thing he had worried about most had indeed happened to Yan Liangfei.

This appearance was precisely the manifestation of his internal energy running rampant and uncontrollably after qi deviation. Previously, Zhang Yang had been right beside Yan Liangfei, so although Yan Liangfei showed signs of qi deviation, Zhang Yang had suppressed it.

He had hoped that after eliminating the Jiang family and settling the Yan family’s great grievance, the heart demon would dissipate, preventing the qi deviation. But in the end, things had gone awry.

After inserting the two silver needles into Yan Liangfei’s temples, Zhang Yang poured his own Great Perfection level internal energy entirely into Yan Liangfei’s body, forcefully suppressing the chaotic internal energy within him and calming it down. Only then did he breathe a sigh of relief!

Zhang Yang released Yan Liangfei, who remained kneeling on the ground like a wooden puppet, devoid of sensation. Sealing the vital acupuncture point of the temples with silver needles and then using internal energy to soothe the turbulent inner strength could only temporarily suppress Yan Liangfei’s internal energy from backlashing.

This was not a long-term solution. If too much time passed, Yan Liangfei would still suffer damage, which would inevitably lead to irreparable regrets in his future cultivation.

There were many ways to ensure Yan Liangfei's future cultivation was completely unaffected by this qi deviation, but this required numerous spiritual herbs, which Zhang Yang hadn't brought with him on this outing. Furthermore, Zhang Yang needed to constantly control the internal energy within Yan Liangfei’s body to prevent it from rebelling again, meaning he couldn't leave Yan Liangfei’s side for too long.

Even with the speed of a spirit beast like Swift Wind, the round trip from the northern suburbs to Changjing would take nearly an hour at the fastest. By the time that much time passed, even if spiritual herbs were brought back, it would be useless.

“Chirp chirp chirp!” Seeing that Zhang Yang had controlled Yan Liangfei, before Zhang Yang could ask, Lightning chirped preemptively from the side, relaying everything that had happened after they entered the villa with Yan Liangfei. “Squeak squeak squeak!” Wuying naturally didn't lag behind and also chirped, and the two little ones, taking turns, narrated everything that transpired inside the villa.

It turned out that the Jiang family members who had fled into the villa also knew that entering the building was tantamount to a dead end. None of them possessed the strength of the third layer of Inner Strength, meaning they couldn't possibly break through the villa's solid walls to escape.

These Jiang family members, once inside the villa, became like ants on a hot pan, spinning around in distress. There was no exit; no matter where they hid, they would eventually be found and ultimately meet their demise.

It was precisely at this moment that Wuying and Lightning rushed into the villa alongside Yan Liangfei. The Jiang family members saw that only Yan Liangfei had entered, and the terrifyingly powerful young man had not followed.

Hope, faint though it was, sparked in their eyes. Yan Liangfei was, after all, only a cultivator at the early stage of the second layer of Inner Strength, while among the Jiang family members, there were quite a few experts at the late stage of the second layer of Inner Strength.

If they could subdue Yan Liangfei, perhaps they could bargain with the young man outside, securing a path to survival. Since the Jiang family members couldn't escape anyway, they decided to risk it all.

A cornered dog will jump over the wall; they banded together, preparing to fight Yan Liangfei to the death. In doing so, they overlooked the two little creatures, Lightning and Wuying—though it was also understandable, as their cultivation was too low for them to even detect the presence of Lightning and Wuying.

After rushing into the villa, Yan Liangfei spotted the fleeing Jiang family members. Ignoring everyone else, he charged toward anyone he saw without regard for his own life.

This perfectly played into the Jiang family’s trap. Although the villa originally belonged to the Wang family in the northern suburbs, the Jiang family, after acquiring it, hadn't bothered to extensively renovate it.

However, they had still laid down quite a few poison arrays within the villa, just in case. Now, these arrays served their purpose.

However, what the Jiang family hadn't anticipated was that when they lured Yan Liangfei into those poison arrays, none of the arrays activated; they all seemed to have malfunctioned. With Swift Wind and Wuying guarding Yan Liangfei, the Jiang family’s petty tricks were naturally useless!

Having no other choice, the Jiang family could only engage Yan Liangfei head-on. Nine of them immediately rushed out to surround and attack Yan Liangfei.

Lightning and Wuying finally revealed themselves at this point; the two little ones each tangled with four opponents, leaving only one for Yan Liangfei to deal with. Unexpectedly, this single Jiang family member left unguarded by Wuying and Lightning—the one Yan Liangfei had to face—led to the accident and ultimate qi deviation.
