Once I enter the pass, great Confucian scholars will surely debate the classics for me.

In the crematorium and mortuary, Ren Wuji, wearing a mask, gloves, and an apron, was professionally stitching up the body of the previous head, chatting casually as he did so.

"What a pity. If you had just two more days, you could have made it through two years."

"But if you're too curious and see things you shouldn't, don't blame me."

"Yes, I know that family members should not be harmed. Your family will not be targeted. This matter ends here."

"You can go in peace."

After Ren Wuji finished sewing up the head of the previous headman, he reached out and pressed a hidden button under the sewing table. The mechanism slowly turned, and the sewing table moved to one side, revealing a staircase leading underground.

Ren Wuji carried the corpse into the underground sewage channel, and the sewing table slowly closed to cover the entrance.

In the underground sewage passage, Ren Wuji patted the storage bag at his waist, took out a human skin lantern, and carried the corpse of the previous person in charge to the far left. He soon arrived at a hidden research room.

The research room was brightly lit, with corpse oil lamps hanging on the walls. Corpses were placed in petri dishes, and Ma Dalang was engrossed in conducting human research. Ren Wuji placed a corpse into a new petri dish.

"The human body is truly a wonderful treasure trove; no matter how much I explore it, it always brings me new surprises."

Wearing a clean medical gown and a single-lens magnifying glass, Ma Dalang said, "I always thought that vital energy was produced by the brain, but after careful research, I discovered that human vital energy is actually produced by the intestines."

"Wonderful, wonderful, absolutely wonderful..." Ma Dalang became so engrossed in his research that he appeared completely delirious.

Ma Dalang's original name was Ma Chunqiu. He was the most outstanding genius in the path of corpses in the history of the Sword Tower. He cultivated the path of corpses to its peak and no one in the entire history of the Sword Tower could surpass his achievements in the path of corpses.

But Ma Dalang was not satisfied with this. From some point onwards, he became obsessed with human body research and studying its mysteries, which resulted in the deaths of tens of thousands of people in the Sword Tower.

When the First Lady discovered this, she was furious and confronted Ma Dalang.

Ma Dalang, too, was stubborn and inflexible, constantly proclaiming, "A little sacrifice is worthwhile for achieving a greater goal."

At that time, Ma Dalang refused to admit his mistake, which infuriated the First Lady. Even if she wanted to protect him, there was no way to do so.

Moreover, this matter caused a huge uproar, becoming widely known, causing public resentment and widespread panic. More importantly, all parties involved in the Sword Tower suffered losses of varying degrees, setting a very bad precedent.

If everyone did what Ma Dalang did, in less than a year, no, at most a month, or even three to five days, mortals would be driven to extinction by cultivators. This is something that those in power absolutely cannot tolerate.

To save her child's life, the First Lady made a behind-the-scenes deal with the First Family, compromising where necessary and sacrificing considerable benefits to save Ma Dalang's life, but the outcome was not pleasant.

At this very moment, a new world fell into the five defilements and evils.

The Python-Sparrow royal family has issued a call to arms, mobilizing the imperial legions to conquer the new world.

So the First Lady took the opportunity to send Ma Dalang to fight in the 'border area'.

A border region, as the name suggests, is a place where the world meets.

The world of five turbidities and evils is the place where the world ends.

Clear air rises and turbid air descends.

If we compare each world imbued with pure energy to a floating bubble.

That world of five turbidities and evils is a murky sea of ​​suffering.

Bubbles float on the sea of ​​suffering, but they always end up falling into it for various reasons.

Whether it is the madness of Heaven, the suffering of living beings, the depletion of pure energy, or the excess of evil desires, the world will slowly degenerate and one day fall into the five turbid evil world, to be swallowed up by evil.

The pure world that has been devoured will fiercely resist the invasion of the turbid and evil world.

The dangers of the border region are self-evident, but Ma Dalang still returned alive with countless merits and earned the title of Heavenly Corpse Demon Lord.

From then on, Ma Dalang's personality changed drastically. His battlefield experience at the border became an indelible nightmare for him. Cultivators from the Pure Qi World and the Five Turbid World engaged in a bloody tug-of-war back and forth at the 'border'.

The 'borderland' didn't give Ma Dalang any time to grow slowly, because someone died every second. All Ma Dalang could do was use every available force to frantically increase his strength; he had no other choice.

In the end, he transformed himself into the inhuman, ghostly creature he is today.

Ma Dalang's battlefield experience at the border made him realize the fragility of life, which made him more determined to engage in human research and pursue the path to immortality.

However, Ma Dalang learned his lesson and outwardly repented, but secretly continued to conduct human research.

The place with the most human bodies in the entire Sword Tower City is the crematorium.

These experimental supplies can be messed with however they want without attracting anyone's attention.

Ma Dalang had already extended his reach here and turned this place into a secret research base.

The previous person in charge was too curious. He followed Ren Wuji here and saw things and people he shouldn't have seen, which led to his death.

Ren Wuji stood to the side, bowing slightly: "Young Master, Zhou Qingfeng has been up there for several days. It seems he is practicing some kind of secret technique and needs to stay at the cremation site temporarily."

Upon hearing the name Zhou Qingfeng, Ma Dalang's manic expression slowly returned to normal: "Keep an eye on him and don't let my fourth brother get hurt. He is my most treasured and invaluable person."

"He cannot be harmed in the slightest until I have figured out how to subdue him."

"And if he needs anything, you should help him out, okay?"

That's right, besides his research, Ma Dalang was obsessed with how to poach talent from others.

Low cultivation level and low realm are not problems at all.

The most important thing is Zhou Qingfeng's extraordinary wisdom. His achievement of annihilating a thousand people with only a hundred men is truly remarkable. This shows the bigger picture from a small example, and the more knowledgeable a person is, the more they understand how terrifying it is.

Ma Dalang believed that with Zhou Qingfeng's assistance, and by taking the manpower and resources he currently possessed, he could expand and strengthen his business wherever he went, creating new glories.

"Understood." Ren Wuji bowed respectfully with a blank expression. Then, his ears twitched as he heard someone calling his name from above. He said, "Young Master, I'm going up. Someone is calling me."

Ma Dalang lowered his head and continued his human body research: "Go."

Ren Wuji turned around, carrying the human skin lantern, and returned to the mortuary along the passage. He straightened his clothes, put away the lantern, calmly opened the door, and stared at the crematorium worker outside with dead fish eyes.

"What is it? Didn't I tell you not to disturb me while I'm working?"

"Master Ren, the Fourth Young Master is leaving, but he said he wants to see you before he leaves."

"Hmm." Ren Wuji's pale face showed no emotion. He simply left the morgue under the guidance of the crematorium worker and then went to meet Zhou Qingfeng.

Soon, Ren Wuji arrived at the front yard of the crematorium: "Fourth Young Master, I was busy with official business and was delayed for a while. Please forgive me."

Zhou Qingfeng stood to the side with a faint smile: "It's nothing. Now that this matter is settled, I was about to leave directly, but before I left, I suddenly remembered a small matter. I would like to ask Manager Ren for a small favor."

"I wonder what kind of help the Fourth Young Master needs from me? Please feel free to ask, and I will do my best without hesitation."

Zhou Qingfeng spread out 10 Death Pearls in his palm: "This place is full of death energy. I would like to trouble you, Manager Ren, to put these 10 Death Pearls in a safe place to prevent the magic artifact from being lost. I will come to pick them up in person after some time."
