How did I, a fake bodyguard, become a terrestrial immortal?

The alley was deathly silent.

Lu Yang looked at the empty ground, then at Captain Qin holding a horizontal sword, and couldn't quite process what was happening.

No.

Where is Fang Xuan?

That huge Fang Xuan was just standing here a moment ago.

How did he and his clothes evaporate together after being stabbed by Captain Qin?

Is the procedure for the death of martial arts masters nowadays so devoid of basic principles?

"Captain Qin..."

Lu Yang slowly turned his head: "You killed my doctor?"

With a flick of his wrist, Captain Qin slowly sheathed his gleaming sword.

Clang!

The crisp sound of the sword being sheathed finally brought Lu Yang back to his senses.

Lu Yang's face darkened, and he stepped forward to block the carriage.

"Fang Xuan is the only one who can save Yao'er."

You'd better give me an explanation today.

The profound aura within Lu Yang's body slowly emerged.

The black tortoise pattern on his back was faintly visible, and even the bluestone slab under his feet made a slight thud.

Several officers from the Zhenwu Division were on high alert, gripping their sword hilts at the same time.

Captain Qin raised his hand to stop the crowd.

"I didn't kill Fang Xuan."

Lu Yang was taken aback: "Not Fang Xuan?"

Captain Qin glanced at the black smoke that had not yet completely dissipated on the ground.

"To be precise, that thing wasn't human at all."

Inside the carriage, Bai Yixin carried Bai Miyao out.

Her face was pale, her gaze fixed on the spot where Fang Xuan had disappeared: "If he wasn't human, then what was he?"

"insanity."

Captain Qin slowly uttered a single word.

"Life-Changing Gu".

Lu Yang's eyelids twitched.

Another Gu worm?

So, I'm destined to be at odds with bugs for the rest of my life?

First, there was the Ice Silkworm Mother Worm inside Han Youwei's body, and now another Metamorphosis Gu that can transform into a human has emerged.

At this rate of development, in a few more chapters, will Ultraman even have to come out and fight monsters?

Captain Qin continued, "The Metamorphosis Gu is an extremely rare evil Gu. It feeds on the blood, flesh, and life force of living people, and once it matures, it can transform into the appearance of that person."

"His appearance, voice, and even his aura are extremely similar to the real person."

"It can even steal a portion of the original owner's memories."

Lu Yang couldn't help but ask, "You mean, that Fang Xuan just now was just a worm in disguise?"

Captain Qin said, "That's one way to understand it."

Lu Yang subconsciously rubbed his arms.

The thought of spending the last few days with a person who was actually an insect gave him goosebumps.

This thing is much scarier than painted skin.

At least, Painted Skin is just a human skin.

The Life-Stealing Gu can even steal memories.

No wonder the fake Fang Xuan not only knew them, but also understood the medical skills of Wanhua Valley, and even knew about the Green Lotus Dao Seed in Bai Miyao's body.

"But he was clearly helping us before."

Bai Yixin's voice trembled slightly: "If he's a fake, why are you helping us?"

Captain Qin glanced at her.

"Because it needs your belief in it."

"A good hunter doesn't pounce on his prey right away."

"It will heal its prey's wounds, cover its prey's scent, and even actively point out a so-called path to survival for its prey."

"Once the prey is completely off guard, it will lead it into the real trap."

Bai Yixin's face turned even paler.

Lu Yang couldn't help but recall Fang Xuan's various behaviors over the past two days.

Since he woke up, Fang Xuan has indeed been acting strangely.

Not only did they proactively tell them that Bai Miyao had the Green Lotus Dao Seed within her, but they also used a secret method to help Bai Miyao avoid the Soul-Illuminating Lamp.

No sooner had the Zhenwu Division left than he urged everyone to leave Hanlin City immediately.

Even when Lu Yang suspected his motives, Fang Xuan did not offer much explanation.

Bai Miyao's life was used to shut down all of Lu Yang's problems.

It now seems that Fang Xuan did not suddenly have a change of heart.

Instead, they planned to pack up the group of people, along with the carriage and provisions, and take them away.

Train services.

It's so thoughtful it's almost frightening.

A sudden wave of fear washed over Lu Yang.

If Commandant Qin hadn't stopped them in time, he probably would have foolishly followed the fake Fang Xuan to the Valley of Ten Thousand Flowers.

At that point, forget about saving Bai Miyao.

Whether all those people in the car would survive to see the gates of the Valley of a Thousand Flowers was questionable.

"etc."

Lu Yang suddenly realized: "How did you know he was a fake?"

Since the Life-Transforming Gu can mimic a person's appearance, voice, and aura, even those who had spent several days with Fang Xuan couldn't detect anything unusual.

How did Captain Qin discover it?

Moreover, judging from that slash just now, he was clearly prepared.

"Because of the Four Gates of Hanlin City's Life-Illuminating Formation."

Captain Qin looked up and glanced at the end of the alley.

"Hanlin City is located in the northern border of Dali. A hundred years ago, it was attacked by demons. Since then, a four-gate fate-illuminating array has been set up underground in the city."

"Everyone who enters or leaves through the city gate will leave a trace of their life force within the formation."

"The formation does not monitor the people on a daily basis, nor can it determine who is good and who is evil. It has only one function."

"Distinguish whether what enters the city is human or demon."

Lu Yang understood.

This thing is like the security check system in Coldfall City.

On ordinary days, it doesn't matter who you are or what you're doing in the city.

As long as it's alive, that's fine.

Although the fake Fang Xuan could mimic appearance and aura, it was essentially a Gu worm without normal life fire.

"Just the day before yesterday, the Illumination Array showed an unusual movement."

Captain Qin said, "The Fate Master in the city who is in charge of guarding the array plates discovered that Fang Xuan's life essence suddenly split in two."

"One side is bright, the other is dark."

"In the lineage of the Fate Masters, this phenomenon is called 'One Fate, Two Shadows'."

"Everyone only has one life."

"The simultaneous appearance of two life energies can only mean that one of them is fake."

Lu Yang frowned and said, "Then why didn't you just go find Fang Xuan directly? Why did you have to check all of us again?"

"Because we can't be sure who the fake one is."

Qin Xiaowei took out a black needle as thin as a cow's hair from his sleeve.

"This is called the Fate-Asking Needle; it's a technique left behind by that Fate Master."

"The Soul-Illuminating Lamp that I brought to the City Lord's Mansion that day was just to deceive people."

"The real instrument used to detect the Life-Transforming Gu is the Life-Asking Needle hidden under the lamp base."

Lu Yang recalled the order of the tests at that time.

The first person to be examined was Fang Xuan!

He found it strange at the time.

After all, Fang Xuan was not a guest at the inn that night, and was the least likely to be related to the Qinglian Sect.

But now it seems that Commandant Qin was after Fang Xuan from the very beginning.

"When the Fate-Asking Needle comes into contact with the Fate-Transforming Gu, it will turn from silver to black."

Captain Qin looked at the black needle in his hand.

"So at that time, I already knew he was a fake."

"Then why didn't you take action on the spot?"

Lu Yang was even more puzzled.

Instead of immediately chopping down the fake one, they pretended nothing had happened and turned to leave the city lord's mansion.

Are you playing Werewolf here?

"The Life-Transforming Gu is extremely vigilant."

Captain Qin said in a deep voice, "Once it realizes its identity has been exposed, it will immediately abandon its Gu body and parasitize the living person closest to it."

"There were many people at the city lord's mansion at the time, and Miss Han had just recovered."

"If we act rashly, the Life-Transforming Gu may parasitize other people."

Lu Yang's expression changed slightly.

At that time, the people closest to Fang Xuan, besides himself, were Bai Yixin and Bai Miyao.

What if that Gu worm suddenly burrows into Bai Miyao's body...?

The little girl was already born with congenital deficiencies, and now she has an additional Green Lotus Dao Seed in her body.

At that time, all three forces will gather together.

There's no need to gather a mahjong table; we can start fighting right inside Bai Miyao's body.

Lu Yang glanced at the sword in Qin Xiaowei's hand.

"Then how dare you lay a hand on me just now?"

"Because of you."

Qin Xiaowei looked at Lu Yang.

Lu Yang was taken aback for a moment, then pointed to himself: "Me?"

"The Fate Master once said that although the Life-Transforming Gu is strange, it is afraid of suppression techniques."

Captain Qin's gaze fell on the faint Xuanwu patterns on Lu Yang's body.

"When you stepped out of the carriage, your vital energy filled the entire alley."

"If the Metamorphosis Gu abandons its Gu body at this moment, it will only be suppressed and killed by your Qi and blood."

Lu Yang finally understood why Captain Qin was so happy to see him.

After all that fuss, it turns out that all I have to do is stand to the side and the insects have nowhere to escape.

What's this called?

The highest level of mastery?

To subdue the enemy without a fight?
