Counterattack System appeared when I'm already At The Mahayana Realm

While Jiang Li knew about poison making in theory, he rarely practiced it, so while he could teach Yu Feng, his knowledge wouldn’t produce the most significant effect.

If the potency of the poison isn’t maximized, it won’t kill at the Foundation Establishment Stage.

“So the Human Emperor wants me to teach this kid how to make poison?” Huang Chengdan, the sect master of the Elixir Sect, was surprised by Jiang Li’s request.

Even though the Elixir Sect used to specialize in poison, it was now reformed. You can’t just order people around. We’ve already rebranded to the Elixir Sect.

“You could find our Medicine Refining Peak.” Bai Hongtu volunteered.

“The herbs you use at the Alchemy Peak are too expensive to afford. It would be better to seek help from the Elixir Sect.”

Seemingly overjoyed that Jiang Li ranked the Elixir Sect above the Alchemy Peak, Huang Chengdan, clearly proud, boasted, “I am the best at making poison… I mean, what kind of poison do you want to make, Human Emperor?”

Jiang Li glanced at Huang Chengdan and introduced him, “This is Sect Master Huang from the Elixir Sect, a cultivator at the Body Integration Realm.”

Yu Feng was surprised. Everyone introduced to him was a cultivator at the Body Integration Realm.

“Greetings, Elder Huang.”

“I want to refine the Body-Dissolving Soul Ointment. These are the raw ingredients.” Jiang Li showcased the prepared poisons, herbs, and black cat blood.

“This is simple; first, we need a medicine furnace.” Sect Master Huang felt the process should be straightforward.

“We don’t have a medicine furnace; let’s make do with the stove.” Jiang Li led Yu Feng to a family’s stove.

There were no medicine furnaces in the town because no one practiced alchemy or poison making.

Huang Chengdan felt like his status had dropped significantly: “…The stove will do.”

Understanding Yu Feng’s novice status and limited resources, Huang Chengdan opted for the most conservative and time-consuming method of medicine refining.

“First, heat the ingredients in a water bath, crush the materials, and put them in while you’re stirring…”

As expected of Huang Chengdan, the most down-to-earth Sect Master of the Elixir Sect, who taught a method of medicine refining that was simple to grasp. Yu Feng learned quickly.

While refining, Yu Feng studied. The theory of medicine refining Huang Chengdan taught him was something he had never touched before.

How could one not listen attentively when a cultivator at the Body Integration Realm was lecturing?

Yu Feng added firewood and worked with the bellows as the crackling sound of burning wood and the whoosh of the bellows filled the kitchen, eventually producing a glimmering translucent gel-like liquid before everyone’s eyes.

“It looks pretty good, but I can’t be sure of its toxicity. Do you want to give it a try?” Bai Hongtu suggested to Yu Feng.

Jiang Li produced the Nine-Turns Immortal Pill: “I’ll let you have a taste when I get back.”

Bai Hongtu quickly shut his mouth.

Jiang Li rolled his eyes and ended the Remote Communication Talisman’s transmission.

“Madam, I’ll have another meat bun.” Yu Feng returned to the bun shop and bought another bun.

“Young man, this is the second time you’ve come here, right? How do you like my buns?”

“They’re great. This is the first time I’ve tasted a bun this good. Are you hiring?”

“We do need more hands now. Come inside and have a chat.” The elderly bun shop owner welcomed Yu Feng warmly and led him into the shop.

Yu Feng felt the world spin around him, and he collapsed onto the ground, unconscious.

When Yu Feng woke up, he found his hands and feet tied up, lying on a kitchen board like a pig ready for slaughter.

A basin containing cut-up raw meat sat nearby. The smell of freshly butchered meat filled the air. Yu Feng guessed it wasn’t from a cow or a pig…

Yu Feng had been to this place several times in his past life. It was all too familiar.

Of all his deaths in his previous life, dying in this place was the worst.

“Have you found any trace of your three junior brothers yet?”

Yu Feng heard the elderly woman talking to someone—the same human trafficker who had killed him and harvested his organs!

“To answer Sect Master, they once mentioned to us that they were going to a small mountain village. I will go and investigate.”

“As the eldest disciple, I trust you can handle this. Don’t rush. Join me in butchering this young fellow first.”

“Understood.”

The elderly woman who sold meat buns was the Sect Leader of the Blood Sea Sect, at the first level of the Foundation Establishment Stage. The trafficker was the Elder Disciple of the Blood Sea Sect, at the ninth level of Qi Cultivation, who ran a street food stall.

“How many people have you killed?” Yu Feng suddenly asked.

Seeing Yu Feng had woken up, the old woman wasn’t surprised and replied, smirking coldly: “Would you keep track of how many buns you’ve eaten?”

“Sect Master, why bother talking to him? Just kill him.” The human trafficker was impatient, wielding his knife, heading toward Yu Feng.

“Do you actually think I’d be so easy to kill?” Yu Feng blew at his hands and feet, and the bindings snapped as though cut by a knife.

“We underestimated you! I hadn’t expected you to be a third-level Qi Cultivator!”

The old woman was shocked. How did a third-level Qi Cultivator hide his stage from her, someone at the Foundation Establishment Stage?

Of course, the old woman didn’t know that the method Yu Feng used to hide his stage was taught to him by Jiang Li. As long as he didn’t use his mana, he could pass as an ordinary person.

“So what if he’s at the third level of Qi Cultivation?” the human trafficker scoffed. Could a third-level Qi Cultivator turn the tide under their noses?

“Why do you think I let you capture me?”

“This kid’s up to something!” Upon realizing this, the old woman quickly launched a spell, but found she couldn’t summon any strength. The spell was only a tenth of its usual might, and Jiang Li’s voice sounded next to Yu Feng’s ear, telling him to dodge it.

“What did you do!” The human trafficker wanted to cast a spell too, but suddenly felt like all his bones were gone, and collapsed on the floor, unable to gather any strength.

The old woman and the human trafficker lay on the floor, their limbs twisted in unnatural angles, looking like boneless octopuses. They were staring at the ceiling, unable to even move their heads.

The Body-Dissolving Soul Ointment was colorless and odorless. It easily evaporated in the smell of blood. At first, nothing would seem amiss. The effect would only take place once someone started using mana. The poison would then dissolve the victim’s bones.

The kitchen was a relatively closed environment, which made the Body-Dissolving Soul Ointment even more potent.

Even a cultivator at the Foundation Establishment Stage couldn’t escape its effect. Without bones, he was just like a lump of flesh.

Yu Feng had taken the antidote beforehand, which is why he was unharmed.

“Friend, let’s talk this out. I’m the Sect Leader of the Blood Sea Sect. Whatever you want, I can give you…” The old woman pleaded.

“Yeah, yeah, it’s all a misunderstanding. We have no grudges, why make things difficult…” The human trafficker was desperate as well.

“No grudges? Didn’t your three junior brothers die by my hand? Isn’t that a grudge?”

“So it was you!” The old woman and the human trafficker widened their eyes in surprise. They hadn’t expected Yu Feng to have such a relationship with the Blood Sea Sect.

Like two worms cut in half, they writhed on the ground helplessly, their bones gone, unable to gather any strength.

“Have you ever thought about how the people who died under your knives must have felt?”

“Please, show mercy…”

Yu Feng said no more. In the manner that they would have killed their victims, Yu Feng bound their mouths and alternately, viciously ripped out the human trafficker’s organs and butchered the old woman into pieces.

As they stopped struggling and their life force diminished, Yu Feng felt a sense of relief, as though he had finally avenged a deep-seated grudge.
